    After practical changes were approved to the initial conceptual design of the cryogenic system for MSU FRIB and an agreement was made with JLab in 2012 to lead the design effort of the cryogenic plant, many activities are in place leading toward a cool-down of the linacs prior to 2018. This is mostly due to using similar equipment used at CHLII for the 12 GeV upgrade at JLab and an aggressive schedule maintained by the MSU Conventional Facilities department. Reported here is an updated status of the cryogenic plant, including the equipment procurement status, plant layout, facility equipment and project schedule.

    Married individuals often have higher body weights than unmarried individuals, but it is unclear how marital roles affect body weight-related perceptions, desires, and behaviors. This study analyzed cross-sectional data for 4,089 adult men and 3,989 adult women using multinomial logistic regression to examine associations between marital status, perceived body weight, desired body weight, and weight management approach. Controlling for demographics and current weight, married or cohabiting women and divorced or separated women more often perceived themselves as overweight and desired to weigh less than women who had never married. Marital status was unrelated to men's weight perception and desired weight change. Marital status was also generally unrelated to weight management approach, except that divorced or separated women were more likely to have intentionally lost weight within the past year compared to never married women. Additionally, never married men were more likely to be attempting to prevent weight gain than married or cohabiting men and widowed men. Overall, married and formerly married women more often perceived themselves as overweight and desired a lower weight. Men's marital status was generally unassociated with weight-related perceptions, desires, and behaviors. Women's but not men's marital roles appear to influence their perceived and desired weight, suggesting that weight management interventions should be sensitive to both marital status and gender differences. © 2013 Elsevier Ltd.

    Objective Radiation fears following Japan's 2011 Fukushima nuclear disaster affected levels of physical activity in local children. We assessed the postdisaster versus predisaster weight status in school children and evaluated to what extent school restrictions on outdoor activities that were intended to reduce radiation exposure risk affected child weight. Participants We considered children aged 13–15 years from 4 of the 5 secondary schools in Soma City (n=1030, 99.1% of all children in the city), located in 35–50 km from the Fukushima nuclear plant, postdisaster (2012 and 2015) and predisaster (2010). Methods Weight status, in terms of body mass index (BMI), percentage of overweight (POW) and incidence of obesity and underweight (defined as a POW ≥20% and ≤−20%, respectively) were examined and compared predisaster and postdisaster using regression models. We also constructed models to assess the impact of school restrictions on outdoor activity on weight status. Results After adjustment for covariates, a slight decrease in mean BMI and POW was detected in females in 2012 (−0.37, 95% CI −0.68 to −0.06; and −1.97, 95% CI −3.57 to −0.36, respectively). For male children, obesity incidence increased in 2012 (OR for obesity: 1.45, 95% CI 1.02 to 2.08). Compared with predisaster weight status, no significant weight change was identified in 2015 in either males or females. School restrictions on outdoor activities were not significantly associated with weight status. Conclusions 4 years following the disaster, weight status has recovered to the predisaster levels for males and females; however, a slight decrease in weight in females and a slight increase in risk of obesity were observed in males 1 year following the disaster. Our findings could be used to guide actions taken during the early phase of a radiological disaster to manage the postdisaster health risks in adolescent children. PMID:27683520

    To assess the agreement between self-perceived weight status and BMI status, calculated from self-reported height and weight, in nurses and to evaluate the relationship between weight status misperceptions and personal body weight, demographics and health status. Cross-sectional questionnaire survey. A large university in London, UK. Four hundred and fifty-six student nurses and 588 qualified nurses attending university were surveyed; 355 student nurses and 409 qualified nurses completed questionnaires representing a response rate of 78 % and 70 %, respectively. The respondents were mainly female (90·0 %), 66·5 % were white and their mean age was 31 years. Sixty-eight per cent of qualified nurses and 77 % of student nurses correctly perceived their weight status. In logistic regression, (mixed) black ethnicity (OR = 2·53, 95 % CI 1·01, 6·32), overweight by BMI (OR = 3·10, 95 % CI 1·31, 7·33) and ≥3 family histories of obesity co-morbidities (OR = 2·51, 95 % CI 1·04, 6·08) were significantly associated with misperceptions in the sample of student nurses, whereas overweight by BMI (OR = 5·32, 95 % CI 2·66, 10·67) was the only significant variable in the sample of qualified nurses. A substantial proportion of nurses misclassified their weight status. Nurses' misperception of weight status was related to their own BMI status, ethnic background and obesity-related family histories. Being aware of this may help nurses not only promote their own healthy weight, but also fulfil their public health role to practise weight management successfully with both patients and the public. While limitations of the sample mean that the study findings cannot be generalized, they do provide grounds for future larger-scale research.

    Full Text Available OBJECTIVES: Diabetes mellitus type 2 (DM 2 patients' self-perception of their weight status is very critical in diabetes care. We sought to investigate perception of weight status in a sample of 200 DM 2 patients attending an outpatient clinic at a Teaching Hospital and compared it with their BMI-measured weight status, with a focus on underestimation of their weight status. Factors associated with underestimation of weight status in this sample were also explored. METHODS: Using a cross-sectional design, anthropometric and clinical variables were assessed using appropriate tools. Questionnaires were used to collect socio-demographic data and self-perception of weight status. Self-perceived weight status was compared to BMI-measured weight status by cross-tabulation, Kappa statistics of agreement and χ2 for trend analysis. Both univariate and multiple logistic regression analysis were conducted to identify factors associated with underestimation of weight status. RESULTS: The prevalence of general overweight/obesity and abdominal obesity was 32.0% (n = 64 and 58.0% (n = 116 respectively. Generally, 58.0% (n = 116 of the participants had a distorted weight perceived weight status in which 77.6% (n = 90 underestimated their weight status. Factors associated with underestimation of weight status were being overweight/obese (AOR = 22.9, 95% CI = 8.30-63.07, p<0.001, not married (AOR = 3.7, 95% CI = 1.50-9.17, p = 0.005 and never tried to lose weight (AOR = 6.9, 95% CI = 2.35-19.97, p<0.001. Participants aged over 40 years and those being hyperglycaemic were not significantly associated to underestimation of weight status. CONCLUSION: We found a substantial discordance between BMI-measured and self-perceived weight status. Factors that were associated with underestimation of weight status were being; overweight/obese, not married and never tried to lose weight. Diabetes patients should be provided with

    The aim of this study was to examine the prevalence of parental misperception of child weight status, and identify socioeconomic, anthropometric, behavioral and dietary factors associated with underestimation. Cross-sectional study. Data was collected in 14 Brazilian private schools. Parents of children aged 2-8 years (n=976) completed a self-reported questionnaire assessing their perception of their child's weight status, and sociodemographic, anthropometric, behavioral and dietary information. To measure the agreement between parental perception about child weight status and actual child weight status, the Kappa coefficient was estimated, and to investigate associations between parental underestimation and independent variables, chi-squared tests were performed, followed by multiple logistic regression, considering p≤0.05 for statistical significance. Overall, 48.05% of the parents incorrectly classified their child's weight. Specifically, 45.08% underestimated their child's weight status, with just 3% of parents overestimating. Children with higher body mass index (OR=2.03; p<0.001) and boys (OR=1.70; p<0.001) were more likely to have their weight status underestimated by parents. Since awareness of weight problems is essential for prevention and treatment, clinical practitioners should help parents at high risk of misperception to correctly evaluate their child's weight status.

To identify and characterize individuals holding misperceptions around their weight status, it may be informative for clinicians to assess self-reported body mass index (BMI classification (ie, underweight, normal, overweight, obese in addition to clinical weight measurement. Methods: Self-reported weight classification data from the 2007 Current Visit Information – Child and Adolescent Survey collected at Mayo Clinic in Rochester, MN, were compared with measured clinical height and weight for 2,993 adolescents. Results: While, overall, 74.2% of adolescents accurately reported their weight status, females, younger adolescents, and proxy (vs self reporters were more accurate. Controlling for demographic and behavioral characteristics, the higher an individual's BMI percentile, the less likely there was agreement between self-report and measured BMI percentile. Those with high BMI who misperceive their weight status were less likely than accurate perceivers to attempt weight loss. Conclusion: Adolescents’ and proxies’ misperception of weight status increases with BMI percentile. Obtaining an adolescent's self-perceived weight status in addition to measured height and weight offers clinicians valuable baseline information to discuss motivation for weight

    Adolescence is characterized by rapid physical growth and sexual maturation. These changes may alter parents' beliefs about their adolescent's weight status. This study aimed to examine the changes between early and mid-adolescence in: (a) the accuracy of maternal perception regarding her adolescent's weight status, (b) the degree of maternal concern about her adolescent's weight status, and (c) the predictors of maternal misclassification of adolescent overweight as average weight. A secondary analysis of the longitudinal Nepean Study data was conducted. Participants were Australian, free-living 13-year-olds in 2002-2003 (n=347) followed up at age 15 years (n=279) and their mothers. Participants' body mass index (BMI) status (overweight, normal, or underweight) was calculated from measured height and weight. Maternal perceptions and concerns about adolescent's weight status were determined by items adapted from the Child Feeding Questionnaire. Sex-adjusted binary logistic regression models assessed potential predictors of maternal misclassification of adolescent overweight. Data were available on 224 adolescent-mother dyads. Approximately one fourth of mothers misclassified their adolescent's weight status, but this varied across groups (age 13 years [%]; age 15 years [%], respectively) underweight (75%; 70%), overweight (54%; 59%), and normal weight (12%; 9%). The endpoint data show that between 13 and 15 years of age, maternal concern regarding their adolescent's weight decreased in all weight-status groups. Predictors of maternal misclassification of adolescent overweight were adolescent BMI z score, recent weight-management practices, weight history, sex, and maternal concern regarding her adolescent's weight. These results reinforce the need for strategies in primary care that are implemented throughout adolescence to improve maternal awareness of childhood overweight.

    The prevalence of overweight and obesity among adolescents is rising rapidly in many countries, including Malaysia. This article aims to present the associations between body mass index-based body weight status, body weight perception, and weight control practices among adolescents in Malaysia. The Malaysia School Based Nutrition Survey 2012, which included a body weight perception questionnaire and anthropometric measurements, was conducted on a representative sample of 40 011 students from Standard 4 until Form 5, with a 90.5% response rate. Comparing actual and perceived body weight status, the findings show that 13.8% of adolescents underestimated their weight, 35.0% overestimated, and 51.2% correctly judged their own weight. Significantly more normal weight girls felt they were overweight, whereas significantly more overweight boys perceived themselves as underweight. The overall appropriateness of weight control practices to body weight was 72.6%. Adolescents attempting to lose or gain weight need to have better understanding toward desirable behavioral changes.

    In plant factories, plants are usually cultivated in nutrient solution under a controllable environment. Plant quality and growth are closely monitored and precisely controlled. For plant growth evaluation, plant weight is an important and commonly used indicator. Traditional plant weight measurements are destructive and laborious. In order to measure and record the plant weight during plant growth, an automated measurement system was designed and developed herein. The weight measurement system comprises a weight measurement device and an imaging system. The weight measurement device consists of a top disk, a bottom disk, a plant holder and a load cell. The load cell with a resolution of 0.1 g converts the plant weight on the plant holder disk to an analog electrical signal for a precise measurement. The top disk and bottom disk are designed to be durable for different plant sizes, so plant weight can be measured continuously throughout the whole growth period, without hindering plant growth. The results show that plant weights measured by the weight measurement device are highly correlated with the weights estimated by the stereo-vision imaging system; hence, plant weight can be measured by either method. The weight growth of selected vegetables growing in the National Taiwan University plant factory were monitored and measured using our automated plant growth weight measurement system. The experimental results demonstrate the functionality, stability and durability of this system. The information gathered by this weight system can be valuable and beneficial for hydroponic plants monitoring research and agricultural research applications. PMID:27066040

    Adolescence represents a pivotal stage in the development of positive or negative body image. Many influences exist during the teen years including transitions (eg, puberty) that affect one's body shape, weight status, and appearance. Weight status exists along a spectrum between being obese (ie, where one's body weight is in the 95th percentile for age and gender) to being underweight. Salient influences on body image include the media, which can target adolescents, and peers who help shape beliefs about the perceived body ideal. Internalization of and pressures to conform to these socially prescribed body ideals help to explain associations between weight status and body image. The concepts of fat talk and weight-related bullying during adolescence greatly contribute to an overemphasis on body weight and appearance as well as the development of negative body perceptions and dissatisfaction surrounding specific body parts. This article provides an overview of the significance of adolescent development in shaping body image, the relationship between body image and adolescent weight status, and the consequences of having a negative body image during adolescence (ie, disordered eating, eating disorders, and dysfunctional exercise). Practical implications for promoting a healthy weight status and positive body image among adolescents will be discussed.

    This study described the nutritional status of 228 pregnant women and the influence of this on birth weight. This is a retrospective study, developed in a health center in the municipality of São Paulo, with data obtained from medical records. Linear regression analysis was carried out. An association was verified between the initial and final nutritional status (ppregnancy underweight was higher compared those who started overweight/obese (p=0.005). Weight gain was insufficient for 43.4% of the pregnant women with adequate initial weight and for 36.4% of all the pregnant women studied. However, 37.1% of those who began the pregnancy overweight/obese finished with excessive weight gain, a condition that ultimately affected almost a quarter of the pregnant women. Anemia and low birth weight were uncommon, however, in the linear regression analysis, birth weight was associated with weight gain (pnutritional care before and during pregnancy to promote maternal-infant health.

    The purpose of this study was to examine the relation of weight status, dieting status and several associated variables to the criteria for everyday food choice used by adolescents. Study participants were 411 students between the ages of 11 and 18, drawn from 15 schools. The adolescents rated 20 food in terms of nine food attributes (how tasty or healthful specific foods were, whether the foods were eaten by friends, and so forth). Within-person correlation coefficients were then calculated between these ratings and actual food choices as measured by a food frequency scale. The relation of weight and dieting status, as predictors of each of these correlational indices of the importance of potential food choice criteria, was then analysed using hierarchical multiple regression. In similar fashion, the relation was examined between weight and dieting status and: evaluations of food attributes (choice criteria); dietary quality; calorie, sugar and fat intake; body image; and physical activity. For a majority of food choice criteria and other variables, there was an apparent influence of weight as an independent variable. However, when dieting status was analysed simultaneously with weight, similar and stronger effects were now seen for dieting status and the effects of weight disappeared. Although some of the differences as a function of dieting status resembled differences shown previously in relation to dietary restraint, it is noteworthy that the simpler dieting variable yielded these associations. Overall, a "psychology of dieting" seems more relevant than "psychology of being fat versus being thin". This psychology appears to involve cognitive self-regulation processes. It is thus crucial that intervention programs and research studies take into account both the dieting status and the weight status of participants.

    The literature on colorectal cancer (CRC screening is contradictory regarding the impact of weight status on CRC screening. This study was intended to determine if CRC screening rates among 2005 National Health Interview Survey (NHIS respondent racial/ethnic and gender subgroups were influenced by weight status. Methods. Univariable and multivariable logistic regression analyses were performed to determine if CRC screening use differed significantly among obese, overweight, and normal-weight individuals in race/ethnic and gender subgroups. Results. Multivariable analyses showed that CRC screening rates did not differ significantly for individuals within these subgroups who were obese or overweight as compared to their normal-weight peers. Conclusion. Weight status does not contribute to disparities in CRC screening in race/ethnicity and gender subgroups.

A survey was undertaken of 1951 mothers living in Chengdu and Wuhan, China and 89 Chinese mothers living in Perth, Australia. All participants were mothers with children aged 2-4 years. The children's weight and height were measured and their weight status were classified using the International Obesity Task Force 2012 revised international child body mass index cut-offs. The prevalence of overweight or obese in children was 16.7% in China and 8% in Australia. The overall percentages of correct maternal perception of the child's weight were 35% in underweight children, 69.2% in normal weight children but only 10.8% in overweight/ obese children. Among the overweight/obese children, only 14% in Australia and 10.8% in China were classified as overweight/obese by their mothers. Within the group of underweight children, normal weight mothers (p=0.004) and mothers with older age children (p=0.015) were more likely to correctly classify children's weight status. A higher percentage of overweight/obese mothers (p=0.002) and mothers who over-estimated her own weight status (pobese children, compared to their counterparts. There was a high prevalence of incorrect maternal perception of preschool children's weight status in Chinese mothers, especially those with overweight/obese children. To address the obesity epidemic in children, future health promotion programs should put improved efforts to educate parents about obesity and its health consequences in order to reduce misperceptions.

    Full Text Available Aim: In Korea, obesity is more prevalent among men and lower socioeconomic groups. To explain this obesity disparity, we compared weight perception and weight control behavior across gender and socioeconomic status (SES. Methods: We analyzed data from 16,260 participants aged 20 years or older in a nationally representative cross-sectional survey. SES indicators included education and income levels. Weight under-perception was defined when participants considered themselves lighter than their measured BMI status. Either no active or inappropriate weight control (i.e., trying to gain weight in obese individuals was considered to be unhealthy patterns. Multivariate prevalence ratios were calculated using log-binomial regressions. Results: Men had a higher prevalence of weight under-perception (24.5 vs. 11.9% and unhealthy patterns of weight control behavior (57 vs. 40% than women. Low education level was associated with weight under-perception (ptrend = 0.022 in men, ptrend trend trend = 0.047 in men, ptrend Conclusion: Weight perception and weight control behavior significantly varied by gender and SES. Public actions should be directed toward improving perception and behavior of high-risk populations.

    A plant health sensing system was developed for determining nitrogen status in plants. The system consists of a multi-spectral optical sensor and a data-acquisition and processing unit. The optical sensor"s light source provides modulated panchromatic illumination of a plant canopy with light-emitting diodes, and the sensor measures spectral reflectance through optical filters that partition the energy into blue, green, red, and near-infrared wavebands. Spectral reflectance of plants is detected in situ, at the four wavebands, in real time. The data-acquisition and processing unit is based on a single board computer that collects data from the multi-spectral sensor and spatial information from a global positioning system receiver. Spectral reflectance at the selected wavebands is analyzed, with algorithms developed during preliminary work, to determine nitrogen status in plants. The plant health sensing system has been tested primarily in the laboratory and field so far, and promising results have been obtained. This article describes the development, theory of operation, and test results of the plant health sensing system.

    Adolescents' self-control weight behaviors were assessed (N = 1961; 12-17 years old; 2007-2008) in the Balearic Islands, Spain. The study analyzed the relationships between body weight status, body image, and self-weight concern, and actual attempts to lose weight by restrained eating and/or increased exercising. In terms of regulatory focus theory (RFT), we considered that efforts to lose or to maintain weight (successful or failed) would be motivated either by a "promotion focus" (to show an attractive body), or a "prevention focus" (to avoid social rejection of fatness), or both. Results showed that 41% of overweight boys and 25% of obese boys stated that they had never made any attempt to lose weight, and 13 and 4% in females. Around half of overweight boys and around a quarter of obese boys stated that they were "Not at all" concerned about weight gain, and girls' percentages decreased to 13 and 11%, respectively. By contrast, 57% of normal weight girls monitored their weight and stated that they had tried to become slim at least once. Weight self-regulation in females attempted to combine diet and exercise, while boys relied almost exclusively on exercise. Apparent lack of consciousness of body weight status among overweight boys, and more important, subsequent absence of behaviors to reduce their weight clearly challenges efforts to prevent obesity. We argue that several causes may be involved in this outcome, including unconscious, emotional (self-defense), and cognitive (dissonance) mechanisms driven by perceived social stigmatization of obesity. The active participation of social values of male and female body image (strong vs. pretty), and the existence of social habituation to overweight are suggested. A better knowledge of psychosocial mechanisms underlying adolescent weight self-control may improve obesity epidemics.

    To analyze the relationship between self-concept, aerobic capacity and weight status in schoolchildren. Relational descriptive design in which was assessed the weight status and aerobic capacity of 256 schoolchildren among 8-11 years. Aerobic capacity (low vs high) and the body mass index (normal-weight vs overweight-obesity) were categorized using standard criteria. The self-concept was assessed through the Piers Harris self-concept scale for children. Schoolchildren with normal-weight and high fitness level showed better levels of conductual self-concept (P=.030), physical (P<.001), lack of anxiety (P=.048), and global self-concept (P=.002). The schoolchildren with normal-weight show higher levels of conductual self-concpt (P=.016), intellectual (P=.050), physical (P<.001), life satisfaction (P=.036), and global self-concept (P=.001). The schoolchildren with a higher fitness level showed better conductual self-concept (P=.024), physical (P=.004), lack of anxiety (P=.011), social (P=.024), and global (P=.003). The results of the study strengthen the importance to transmit to the educative community the knowledge of the relationship between the variables analyzed aiming to improve the schoolchildren self-concept.

    Postpartal weight loss, nutritional intake, and immune status were examined in 65 women. Although 80% of the women lost weight and were not overweight by the 4th postpartal month, the majority had diets that were inadequate in fat content (> or = 30% of calories from fat) or protein content ( or = 2,200 calories). Differences in some immune cell subsets were noted between women with high-fat and normal-fat diets. Women with high-fat diets had lower percentages of specific immune cell subsets than women with normal-fat diets. Protein intake was not related to immune cell phenotypes.

    Pediatric overweight is currently reaching epidemic proportions but little information exists on differences in weight related behaviors between urban and rural children. To assess health behaviors and weight status among urban and rural school-age children. Fifth-grade children at two urban and two rural schools were invited to participate in an assessment study of their health behaviors and weight status. A total of 138 children (mean age = 10 years; % female = 54.6) chose to participate. Children in rural and urban areas consumed equivalent calories per day and calories from fat, but rural children ate more junk food and urban children were more likely to skip breakfast. Urban children engaged in more metabolic equivalent tasks and had slightly higher total sedentary activity than rural children. The BMI percentile was equivalent across rural and urban children but rural children were more often overweight and urban children were more often at risk for overweight. Although some variables were equivalent across urban and rural children, results indicate some key health behavior differences between groups. Results should be interpreted with caution as the sample size was small and there were demographic differences between urban and rural samples.

    Full Text Available The objective of this study is to examine the association between impulsivity and weight status in a large sample of the adult general population in France, and the influence of gender on this relationship. A total of 11,929 men and 39,114 women participating in the NutriNet-Santé cohort were selected in this cross-sectional analysis. The Barratt Impulsiveness Scale (BIS-11 was used to assess impulsivity. Weight and height were self-reported. The association between impulsivity and BMI was estimated using logistic regressions adjusted for socio-demographic and lifestyle factors. Individuals with high impulsivity levels (BIS-11 total score >71 were more likely to be obese (Odds Ratio (OR = 1.80, 95% Confidence Interval (CI: 1.39, 2.33 in men; OR = 1.30, 95% CI: 1.15, 1.48 in women compared to individuals in the average range of impulsivity. The strongest associations between impulsivity and obesity were observed in men, where highly impulsive participants were more likely to be class III obese (BMI > 40 kg/m2 (OR = 3.57, 95% CI: 1.86, 6.85. This large sample analysis supports the existence of a relationship between impulsivity and weight status and the importance of psychological factors in the prevention of obesity.

The early research on this topic produced mixed findings. About one-half of the early studies showed that obese men overestimated their body size, with the remaining half providing accurate estimates. Later, improvements in research technology and methodology provided a clearer indication of the role of weight status in body image perception. Research in our laboratory has also produced diverse findings, including that obese subjects sometimes overestimate their body size. However, when examining our findings across several studies, obese subjects had about the same level of accuracy in estimating their body size as normal-weight subjects. Studies in our laboratory also permitted the separation of sensory and nonsensory factors in body image perception. In all but one instance, no differences were found overall between the ability of obese and normal-weight subjects to detect overall changes in body size. Importantly, however, obese subjects are better at detecting changes in their body size when the image is distorted to be too thin as compared to too wide. Both obese and normal-weight men require about a 3%–7% change in the width of their body size in order to detect the change reliably. Correlations between a range of body mass index values and body size estimation accuracy indicated no relationship between these variables. Numerous studies in other laboratories asked men to place their body size into discrete categorizes, ranging from thin to obese. Researchers found that overweight and obese men underestimate their weight status, and that men are less accurate in their categorizations than

    The pathogenesis of hypertension begins in youth. An estimated 4% of US adolescents have diagnosed hypertension and 17% have elevated blood pressures, predisposing them to hypertension and cardiovascular disease (CVD) later in life. There is limited research on the clustering of CVD risk factors such as tobacco exposure and weight status that may be associated with high blood pressure in adolescents. The aim of this exploratory study was to determine the relationships between total smoke exposure (TSE; cigarette smoking and secondhand smoke), waist circumference, and blood pressure in a sample of rural adolescents, ages 15-18. A convenience sample of 148 adolescents ages 15-18 was recruited from two rural high schools (88 female and 60 male, all Caucasian). Adolescents were assessed for tobacco exposure (self-report, salivary cotinine), weight status (body mass index, waist circumference), and blood pressure. Self-report measures of tobacco exposure included the Uptake Continuum and Peer and Family Smoking measure. Age, gender, waist circumference and salivary cotinine contributed to 35% of the variance in systolic blood pressure and 18% in diastolic blood pressure. One-fourth (25%) of adolescent males and 11% of adolescent females had elevated systolic blood pressures. Approximately one-fifth of the sample (22%) had elevated salivary cotinine levels indicative of tobacco use and secondhand smoke exposure. TSE and waist circumference were predictors of elevated blood pressure in adolescents. Public health measures need to address clusters of risk factors including blood pressure, tobacco exposure, and weight status among adolescents in order to reduce CVD.

    The purpose of this study was to (1) examine the association between weight status and men's positive mental health, defined as the presence of symptoms of emotional, psychological, and social well-being, and (2) evaluate the moderating effect of marital status. A total of 645 men aged between 19 and 71 years self-reported their height and weight and answered a questionnaire measuring their emotional, psychological, and social well-being. Analysis of variance revealed that mean levels of emotional, psychological, and social well-being did not significantly differ according to men's weight status. Moderation analyses indicated that, for men in a relationship (married or living common-law), there were no significant associations between overweight, obesity, and the three components of positive mental health. However, for single men, overweight was marginally associated with higher emotional well-being, while obesity was associated with lower psychological well-being and marginally associated with lower social well-being. Results of the present study suggest that health professionals and researchers should take the characteristics (such as marital status) of men with obesity and overweight into account when working with them. Mental health researchers may need to examine men in each weight category separately (e.g. obesity vs. overweight), since the association with positive mental health can differ from one category to another.

  8. Does parenting affect children's eating and weight status?

    2008-03-01

    Full Text Available Abstract Background Worldwide, the prevalence of obesity among children has increased dramatically. Although the etiology of childhood obesity is multifactorial, to date, most preventive interventions have focused on school-aged children in school settings and have met with limited success. In this review, we focus on another set of influences that impact the development of children's eating and weight status: parenting and feeding styles and practices. Our review has two aims: (1 to assess the extent to which current evidence supports the hypothesis that parenting, via its effects on children's eating, is causally implicated in childhood obesity; and (2 to identify a set of promising strategies that target aspects of parenting, which can be further evaluated as possible components in childhood obesity prevention. Methods A literature review was conducted between October 2006 and January 2007. Studies published before January 2007 that assessed the association between some combination of parenting, child eating and child weight variables were included. Results A total of 66 articles met the inclusion criteria. The preponderance of these studies focused on the association between parenting and child eating. Although there was substantial experimental evidence for the influence of parenting practices, such as pressure, restriction, modeling and availability, on child eating, the majority of the evidence for the association between parenting and child weight, or the mediation of this association by child eating, was cross-sectional. Conclusion To date, there is substantial causal evidence that parenting affects child eating and there is much correlational evidence that child eating and weight influence parenting. There are few studies, however, that have used appropriate meditational designs to provide causal evidence for the indirect effect of parenting on weight status via effects on child eating. A new approach is suggested for evaluating the

    This study examined associations of accessibility, availability, price, and quality of food choices and neighborhood urban design with weight status and utilitarian walking. To account for self-selection bias, data on adult residents of a middle-to-high-income neighborhood were used. Participants kept a 2-day activity/travel diary and self-reported socio-demographics, height, and weight. Geographic Information Systems data were used to objectively quantify walking-related aspects of urban design, and number of and distance to food outlets within respondents' 1km residential buffers. Food outlets were audited for availability, price, and quality of healthful food choices. Number of convenience stores and in-store healthful food choices were positively related to walking for errands which, in turn, was predictive of lower risk of being overweight/obese. Negative associations with overweight/obesity unexplained by walking were found for number of grocery stores and healthful food choices in sit-down restaurants. Aspects of urban form and food environment were associated with walking for eating purposes which, however, was not predictive of overweight/obesity. Access to diverse destinations, food outlets and healthful food choices may promote pedestrian activity and contribute to better weight regulation. Accessibility and availability of healthful food choices may lower the risk of overweight/obesity by providing opportunities for healthier dietary patterns.

    Full Text Available Abstract Background Excessive gestational weight gain promotes poor maternal and child health outcomes. Weight misperception is associated with weight gain in non-pregnant women, but no data exist during pregnancy. The purpose of this study was to examine the association of misperceived pre-pregnancy body weight status with excessive gestational weight gain. Methods At study enrollment, participants in Project Viva reported weight, height, and perceived body weight status by questionnaire. Our study sample comprised 1537 women who had either normal or overweight/obese pre-pregnancy BMI. We created 2 categories of pre-pregnancy body weight status misperception: normal weight women who identified themselves as overweight ('overassessors' and overweight/obese women who identified themselves as average or underweight ('underassessors'. Women who correctly perceived their body weight status were classified as either normal weight or overweight/obese accurate assessors. We performed multivariable logistic regression to determine the odds of excessive gestational weight gain according to 1990 Institute of Medicine guidelines. Results Of the 1029 women with normal pre-pregnancy BMI, 898 (87% accurately perceived and 131 (13% overassessed their weight status. 508 women were overweight/obese, of whom 438 (86% accurately perceived and 70 (14% underassessed their pre-pregnancy weight status.

    Over the past three decades there has been a surge in the prevalence of overweight and obesity worldwide in both adults and children. To date few studies have examined obesity in India and most have only looked at prevalence estimates. While studies in Western countries have identified parent weight status as a predictor of child weight status, there have been no studies examining this association in India. This study examined the relationship between parent weight status and child weight status using an internationally representative growth reference for children and Asian-specific action points for adults.Overall, this study found 29.6% of children and 77.7% of parents in a sample of private schools in Delhi, India were overweight/obese. Parent weight status was found to be associated with child weight status after controlling for child grade and sex. However, while maternal weight status was associated with child weight status (odds ratio=1.51, 95% confidence interval: 1.04-2.20), paternal weight status was not (odds ratio=1.10, 95% confidence interval: 0.81-1.48). The association was greatest between mothers and sons (odds ratio=2.13, 95% confidence interval: 1.39-3.27).These results provide initial evidence that parent weight status is associated with child weight status in Delhi, India. Future research should continue to explore the relationship between parent, particularly maternal, and child weight status to better understand the nature of the relationship and the differences between male and female children. Interventions to address child overweight and obesity in India should include parents as direct targets. © The Author(s) 2016.

    Obesity is associated with decreased compliance with cancer screening, but with an increased risk for cancer development. However, the relationship between weight status and compliance with stomach cancer screening has not been not studied as yet. We examined men and women aged between 40 and 80 years from the 4th Korea National Health and Nutrition Examination Survey from 2007 to 2009. BMI was classified into ≤18.4 kg/m (underweight), 18.5-22.9 kg/m (normal), 23-24.9 kg/m (overweight), 25.0-29.9 kg/m (moderate obesity), and ≥30.0 kg/m (severe obesity). Screening compliance was defined as undergoing stomach cancer screening every 2 years with either gastroscopy or upper gastrointestinal series. The overall screening rates of stomach cancer were 43.2 (0.9)% for men and 43.4 (0.8)% for women. After adjustment for covariates, the screening rates were higher in overweight men (adjusted odds ratio, 1.19; 95% confidence interval, 0.98-1.44), with a marginal significance, and significantly lower in women with severe obesity (adjusted odds ratio, 0.55; 95% confidence interval, 0.40-0.76). The difference was mainly driven by the lower acceptance of gastroscopy rather than upper gastrointestinal series. In conclusion, obesity is associated with lower compliance with stomach cancer screening in Korean women. Therefore, new strategies need to be developed to improve the cancer screening compliance in obese women.

    Full Text Available Abstract Background Recent studies have shown that body image perception is an important factor in weight control and may be influenced by culture and ethnicity. The aim of the present study was to assess the relationship between immigrant status of the mother and weight status and body image perception of the child. Methods In total, 2706 schoolchildren (1405 boys and 1301 girls aged 8–9 years and their mothers participated in a cross-sectional survey in Emilia-Romagna region (northern Italy. Weight and height of the children were measured and Body Mass Index (BMI was calculated. Actual and ideal body image perception by the children and by the mothers with respect to their children was evaluated according to Collins’ body image silhouettes. Results The BMI values were significantly lower in children of immigrants than in children of Italian mothers (F:17.27 vs 17.99 kg/m2; M:17.77 vs 18.13 kg/m2. The prevalence of overweight/obesity was lower, and the prevalence of underweight higher, in children of immigrant mothers than in those of Italian mothers (overweight- F:21.3 vs 29.1%; M. 28.3 vs 31.4%; underweight- F:5.16 vs 3.84%; M:6.63 vs 2.82%. The children's body image perception was consistent with the differing pattern of nutritional status. In the comparison between actual and ideal figures, the Feel-Ideal Difference Index (FID scores resulted different between the subsample with foreign-born mother in comparison to the native one (significantly lower in daughters of immigrants (FID- F: 0.31 vs 0.57; M: 0.35 vs 0.32. There were significant differences in the choice of the ideal figure of the child between immigrant mothers and Italian mothers (FID- F: -0.05 vs 0.19; M: -0.35 vs −0.03: the ideal figure values were higher in the immigrant mothers of male children and lower in the Italian mothers of female children. Conclusion Our results suggest that cultural and behavioral factors linked to ethnicity play an important role in the

    The effect of diet quality on weight change, relative to other body weight determinants, is insufficiently understood. Furthermore, research on long-term weight change in U.S. adults is limited. We evaluated prospectively patterns and predictors of weight change in Framingham Offspring/Spouse (FOS) women and men (n = 1515) aged > or =30 y with BMI > or = 18.5 kg/m2 and without cardiovascular disease, diabetes, and cancer at baseline over a 16-y period. Diet quality was assessed using the validated Framingham Nutritional Risk Score. In women, older age (P < 0.0001) and physical activity (P < 0.05) were associated with lower weight gain. Diet quality interacted with former smoking status (P-interaction = 0.02); former smokers with lower diet quality gained an additional 5.2 kg compared with those with higher diet quality (multivariable-adjusted P-trend = 0.06). Among men, older age (P < 0.0001) and current smoking (P < 0.01) were associated with lower weight gain, and weight fluctuation (P < 0.01) and former smoking status (P < 0.0001) were associated with greater weight gain. Age was the strongest predictor of weight change in both women (partial R(2) = 11%) and men (partial R(2) = 8.6%). Normal- and overweight women gained more than obese women (P < 0.05) and younger adults gained more weight than older adults (P < 0.0001). Patterns and predictors of weight change differ by sex. Age in both sexes and physical activity among women as well as weight fluctuation and smoking status in men were stronger predictors of weight change than diet quality among FOS adults. Women who stopped smoking over follow-up and had poor diet quality gained the most weight. Preventive interventions need to be sex-specific and consider lifestyle factors.

    It is still debated whether alien plants benefit from being mycorrhizal, or if engaging in the symbiosis constrains their establishment and spread in new regions. We analyzed the association between mycorrhizal status of alien plant species in Germany and their invasion success. We compared whether the representation of species with different mycorrhizal status (obligate, facultative, or non-mycorrhizal) differed at several stages of the invasion process. We used generalized linear models to explain the occupied geographical range of alien plants, incorporating interactions of mycorrhizal status with plant traits related to morphology, reproduction, and life-history. Non-naturalized aliens did not differ from naturalized aliens in the relative frequency of different mycorrhizal status categories. Mycorrhizal status significantly explained the occupied range of alien plants; with facultative mycorrhizal species inhabiting a larger range than non-mycorrhizal aliens and obligate mycorrhizal plant species taking an intermediate position. Aliens with storage organs, shoot metamorphoses, or specialized structures promoting vegetative dispersal occupied a larger range when being facultative mycorrhizal. We conclude that being mycorrhizal is important for the persistence of aliens in Germany and constitutes an advantage compared to being non-mycorrhizal. Being facultative mycorrhizal seems to be especially advantageous for successful spread, as the flexibility of this mycorrhizal status may enable plants to use a broader set of ecological strategies.

    Full Text Available Background: To examine macronutrient and micronutrient intake of adolescent girls of Tehran, capital of Iran to discover any malnutrition in relation to weight status and dieting.Methods: A cross-sectional study was conducted. Four hundred 11- to 17-year-old students were selected by multistage clus­ter sampling from secondary and high schools of Tehran. The information about dietary intakes was taken by food fre­quency questionnaire and 24-hour recall form. The students' body mass indices (BMIs were measured and were classified ac­cording to National Center for Health Statistics /Center for Disease Control and Prevention (2000 growth charts. Partici­pants were also questioned about body image and dieting. Results: 6.7% of adolescent girls were classified as being obese, 14.6% overweight, 75.4% normal and 3.2% underweight. Stu­dents 11-13 year old, had mean intakes lower than estimated average requirement (EAR for folic acid, vitamin E, cal­cium, magnesium, phosphorus, potassium and sodium, and 14-18 year old students had mean intakes lower than EAR for nia­cin, pyridoxine, folic acid, pantothenic acid, vitamin E, calcium, magnesium, phosphorus, potassium, sodium and zinc. Obese and overweight adolescents had less carbohydrate, thiamin, niacin, iron and selenium intake. The participants, who were dieting, used significantly less amounts of proteins, carbohydrates, thiamin, niacin, iron, selenium, sodium and zinc.Conclusion: Knowing the harmful consequences of nutrient deficiency especially in adolescents, nutrition education must be emphasized in schools to promote nutritional literacy.

    Plant protoplasts ("naked" cells) provide a unique single cell system to underpin several aspects of modern biotechnology. Major advances in genomics, proteomics, and metabolomics have stimulated renewed interest in these osmotically fragile wall-less cells. Reliable procedures are available to isolate and culture protoplasts from a range of plants, including both monocotyledonous and dicotyledonous crops. Several parameters, particularly the source tissue, culture medium, and environmental factors, influence the ability of protoplasts and protoplast-derived cells to express their totipotency and to develop into fertile plants. Importantly, novel approaches to maximise the efficiency of protoplast-to-plant systems include techniques already well established for animal and microbial cells, such as electrostimulation and exposure of protoplasts to surfactants and respiratory gas carriers, especially perfluorochemicals and hemoglobin. However, despite at least four decades of concerted effort and technology transfer between laboratories worldwide, many species still remain recalcitrant in culture. Nevertheless, isolated protoplasts are unique to a range of experimental procedures. In the context of plant genetic manipulation, somatic hybridisation by protoplast fusion enables nuclear and cytoplasmic genomes to be combined, fully or partially, at the interspecific and intergeneric levels to circumvent naturally occurring sexual incompatibility barriers. Uptake of isolated DNA into protoplasts provides the basis for transient and stable nuclear transformation, and also organelle transformation to generate transplastomic plants. Isolated protoplasts are also exploited in numerous miscellaneous studies involving membrane function, cell structure, synthesis of pharmaceutical products, and toxicological assessments. This review focuses upon the most recent developments in protoplast-based technologies.

    The prevalence of weight disorders among school-aged children is an increasing phenomenon and it is of great importance to identify the characteristics of individuals at risk of gaining or retaining weight. This study aimed to examine the prevalence of weight disorders and their tracking over a 3-year period in a sample of Italian children. Body mass, body height and selected skinfold thicknesses were assessed in 355 children at the age of 7 and 10 years. Tracking of body mass index (BMI), inverted BMI (iBMI) and skinfold-based body fat were analyzed and the relationships between changes in BMI and body fat were examined. Children presenting with overweight or obesity at 7 years old showed a trend toward lower weight categories at 10 years old. Conversely, a trend to become overweight was observed among normal weight boys, and a trend to become underweight was observed among normal weight girls. BMI, iBMI and body fat showed good levels of tracking, with high correlations between measurements performed at 7 and 10 years of age. Furthermore, BMI and iBMI changes were correlated to body fatness changes. The present study shows the importance of carefully following children's development over time because weight disorders may appear even in previously normal weight children.

    Full Text Available Plants have developed a wide-range of adaptations to overcome nutrient limitation, including changes to the quantity and composition of carbon-containing compounds released by roots. Root-associated bacteria are largely influenced by these compounds which can be perceived as signals or substrates. Here, we evaluate the effect of root exudates collected from maize plants grown under nitrogen (N, phosphate (P, iron (Fe and potassium (K deficiencies on the transcriptome of the plant growth promoting rhizobacterium (PGPR Bacillus amyloliquefaciens FZB42. The largest shifts in gene expression patterns were observed in cells exposed to exudates from N-, followed by P-deficient plants. Exudates from N-deprived maize triggered a general stress response in FZB42 in the exponential growth phase, which was evidenced by the suppression of numerous genes involved in protein synthesis. Exudates from P-deficient plants induced bacterial genes involved in chemotaxis and motility whilst exudates released by Fe and K deficient plants did not cause dramatic changes in the bacterial transcriptome during exponential growth phase. Global transcriptional changes in bacteria elicited by nutrient deficient maize exudates were significantly correlated with concentrations of the amino acids aspartate, valine and glutamate in root exudates suggesting that transcriptional profiling of FZB42 associated with metabolomics of N, P, Fe and K-deficient maize root exudates is a powerful approach to better understand plant-microbe interactions under conditions of nutritional stress.

    Recognising overweight and obesity is critical to prompting action, and consequently preventing and treating obesity. The present study examined the association between parental perceptions of child weight status and child's diet. Participants were members of the Gateshead Millennium Study. Parental perception of their child's weight status was assessed using a questionnaire and compared against International Obesity Task Force cut-offs for childhood overweight and obesity when the children were aged 6-8 years old. Diet was assessed at age 6-8years old using the FAST (Food Assessment in Schools Tool) food diary method. The association between parental perception and dietary patterns as defined by Principal Components Analysis, was assessed using multivariate regression after adjustment for child's gender, child's weight status, maternal body mass index (BMI), maternal education and deprivation status. Of the 361 parents who provided complete data on confounders and on their perception of their child's weight status, 63 (17%) parents perceived their child as being of 'normal' weight or 'overweight' when they were actually 'overweight' or 'obese', respectively. After adjustment for confounders, parents who misperceived their child's weight had children with a lower 'healthy' dietary pattern score compared to children whose parents correctly perceived their weight (β = -0.88; 95% CI: -1.7, -0.1; P-value = 0.028). This association was found despite higher consumption of reduced sugar carbonated drinks amongst children whose parents incorrectly perceived their weight status compared to children whose parents perceived their weight correctly (52.4% vs. 33.6%; P-value = 0.005). In conclusion, children whose parents did not correctly perceive their weight status scored lower on the 'healthy' dietary pattern. Further research is required to define parents' diets based on their perception status and to examine if a child's or parent's diet mediates the association between

    Full Text Available Post-genomics era has witnessed the development of cutting-edge technologies that have offered cost-efficient and high-throughput ways for molecular characterization of the function of a cell or organism. Large-scale metabolite profiling assays have allowed researchers to access the global data sets of metabolites and the corresponding metabolic pathways in an unprecedented way. Recent efforts in metabolomics have been directed to improve the quality along with a major focus on yield related traits. Importantly, an integration of metabolomics with other approaches such as quantitative genetics, transcriptomics and genetic modification has established its immense relevance to plant improvement. An effective combination of these modern approaches guides researchers to pinpoint the functional gene(s and the characterization of massive metabolites, in order to prioritize the candidate genes for downstream analyses and ultimately, offering trait specific markers to improve commercially important traits. This in turn will improve the ability of a plant breeder by allowing him to make more informed decisions. Given this, the present review captures the significant leads gained in the past decade in the field of plant metabolomics accompanied by a brief discussion on the current contribution and the future scope of metabolomics to accelerate plant improvement.

    We have a limited understanding of the objectively determined physical activity levels by weight control status (i.e., trying to lose weight, trying to maintain weight, and neither trying to lose or maintain weight) among U.S. adults with diabetes. Therefore, this study assessed the association between physical activity and weight control status among U.S. adults with diabetes. Cross-sectional survey. The 2003-2006 National Health and Nutrition Examination Survey (NHANES) was used, which is representative of the U.S. population. Subjects were 733 adults (≥20 years) with diabetes. Participants wore an accelerometer to assess physical activity, and questionnaires were used to assess weight control status and covariates. Multivariate negative binomial regressions were used. After adjustments, and compared to those not trying to lose or maintain their weight, women trying to lose weight engaged in 74% more physical activity (rate ratio = 1.74; 95% confidence interval [CI]: 1.14 to 2.65). Although findings were not significant for men, men were more likely than women to meet physical activity recommendations. Diabetic women trying to lose weight engaged in more physical activity than did their female counterparts not trying to lose or maintain their weight. Although men were more active than women, no differences in activity estimates occurred across weight control status for men.

    Recent research indicates that chewing behavior may influence energy intake and energy expenditure. However, little is known about the relationship between chewing behavior and body weight status. In the present study, 64 fully dentate normal-weight or overweight/obese adults were asked to consume five portions of a test food and the number of chewing cycles, chewing duration before swallowing and chewing rate were measured. Adjusting for age and gender, normal-weight participants used a higher number of chewing cycles (p = 0.003) and a longer chewing duration (p weight status in fully dentate healthy adults.

    The aim of this study was to evaluate the ability of parents to estimate the weight status of preschool children attending the Instituto Mexicano del Seguro Social (IMSS) day-care centers using three different tools. A total of 100 parent-child pairs attending to all the existing IMSS day-care centers in Ensenada (n = 9) completed a questionnaire on the perception of children's weight status using verbal description, sketches, and pictures. Chi squared test and univariate logistic regression was applied to assess the difference in perception between the tools used, the factors associated with the weight status perception and to identify predictors of parental underestimation of their child's weight. The sample size was estimated for a significance level of 0.05 with statistical power of 80%. No significant differences were found in the perception of weight status using different tools. The parents' underestimation of the child's weight status ranged from 51 to 59%, this percentage jumps to 79 to 84% in overweight children and 82 to 91% in obese children. Being a young mother and having a daughter increased the risk of underestimation. Higher odds of underestimation were found in > 2BMI z-score. The high underestimation found in this study shows that the ability of parents in signaling an alert to prevent childhood obesity might be highly reduced and preventive health programs should include increasing the weight status perception.

    Pumped storage plants (PSP) enable the storage of energy with rated capacities of order of GW at a single site. Reservoirs allow charging and discharging times of at least hours, sometimes days or even up to several weeks. Short ramp-up times permit the participation in the secondary reserve market as a standing reserve. For bulk energy storage, PSP reach the lowest, specific costs. In the EU27 countries, Norway and Switzerland, a total of 44 GW of pumped storage capacity is installed. The utilisation of PSP strongly correlates with the amount of conventional generation capacity, rather than with topographical options. (orig.)

    Full Text Available Background. Socioeconomic status and birth weight are prominent factors for future growing of children. Also Studies show that this criterion is associated with reduced cognitive outcomes, school achievement, and adult work capacity. So in this paper we determined the effects of some socio-economic statuses and birth weight on physical growth of children in Mashhad, Iran. Method and materials. This is a cross sectional study that determined effect of socio-economic status and birth weight on weight, heighting and BMI of school age children. Healthy six years old children who were screened before enter, to school were eligible for participating in our study between 6 June 2006 and 31 July. Weight and standing height were documented at birth and measured at 6 years old. Then, their BMI were calculated in childhood period. Data were analyzed by using SPSS software. Result. Results show that some socio-economic variables and birth weight is associated with and, perhaps, influence the variation of growth in the children. The variables which show the most consistent and significant association were birth weight, sex, economic status and education of parents. Conclusion. In this paper, we found that birth weight, economic status and education parents of neonates have directly significant effect on growth childhood period. We recommended that paying attention to these criteria for improving growth of children in our society should be considered by authorities.

    Full Text Available BACKGROUND: Parental obesity is a predominant risk factor for childhood obesity. Family factors including socio-economic status (SES play a role in determining parent weight. It is essential to unpick how shared family factors impact on child weight. This study aims to investigate the association between measured parent weight status, familial socio-economic factors and the risk of childhood obesity at age 9. METHODOLOGY/PRINCIPAL FINDINGS: Cross sectional analysis of the first wave (2008 of the Growing Up in Ireland (GUI study. GUI is a nationally representative study of 9-year-old children (N = 8,568. Schools were selected from the national total (response rate 82% and age eligible children (response rate 57% were invited to participate.

    Parental obesity is a predominant risk factor for childhood obesity. Family factors including socio-economic status (SES) play a role in determining parent weight. It is essential to unpick how shared family factors impact on child weight. This study aims to investigate the association between measured parent weight status, familial socio-economic factors and the risk of childhood obesity at age 9. Cross sectional analysis of the first wave (2008) of the Growing Up in Ireland (GUI) study. GUI is a nationally representative study of 9-year-old children (N = 8,568). Schools were selected from the national total (response rate 82%) and age eligible children (response rate 57%) were invited to participate. Children and their parents had height and weight measurements taken using standard methods. Data were reweighted to account for the sampling design. Childhood overweight and obesity prevalence were calculated using International Obesity Taskforce definitions. Multinomial logistic regression examined the association between parent weight status, indicators of SES and child weight. Overall, 25% of children were either overweight (19.3%) or obese (6.6%). Parental obesity was a significant predictor of child obesity.

    Maternal nutritional status of pre pregnancy and gestational weight gain affects the preterm birth. The association between maternal nutritional status of pre pregnancy and preterm birth appears to be complex and varied by studies from different countries, thus this association between the gestational weight gain and preterm birth is more consolidated. The study aims to determine any association between the pre pregnancy maternal nutritional status, gestational weight gain and the preterm birth rate in the Albanian context. In case control study, we analyzed women who have delivered in obstetric institutions in Tirana during the year 2012. Body mass index and gestational weight gain of 150 women who had a preterm delivery were compared with those of 150 matched control women who had a normal delivery regarding the gestation age. The self-reported pre pregnancy weight, height, gestational weight gain, age, education and parity are collected through a structured questioner. The body mass index and gestational weight gain are categorized based on the Institute of Medicine recommendation. The multiple logistic regression is used to measure the association between the nutritional status of pre pregnancy and gestational weight gain and the preterm birth rate. The women which have a underweight status or obese of pre pregnancy are more likely to have a preterm birth compared to the women of a normal pre-pregnancy nutritional status (respectively OR =2.7 and 4.3 pnutritional status and gestational weight gain affects the risk for preterm birth. Pre-pregnancy and gestation nutritional assessments should be part of routine prenatal visits.

    The Healthy Communities Study is one of the largest studies to assess the relationship between characteristics of community programs and policies to prevent childhood obesity and obesity-related outcomes. The purpose of this paper is to describe the protocol that was developed for collecting the anthropometric data for the study and the procedures for analyzing the data. Data were collected from 2013 to 2015 and analyses will be completed by mid-2016. During in-home visits, Healthy Communities Study staff collected height, weight, and waist circumference measurements from child participants and height and weight measurements from adult participants. The protocol for obtaining these measurements was adapted from the protocol used by the National Health and Nutrition Examination Survey, with modifications to accommodate assessments conducted in homes rather than in a Mobile Examination Center. In addition to anthropometric data from in-home visits, the Healthy Communities Study collected retrospective height and weight measurements from the medical records of child participants. These data were used to calculate trajectories of BMI and BMI z-scores. The study implemented procedures for ensuring the accuracy of the in-home measurements and abstracted medical data. These procedures included automatically checking the ranges on entered data, reviewing data for end-digit patterns, and abstracting selected medical records using two independent abstractors to assess agreement. The collection of longitudinal height and weight measures will allow researchers to address several pressing questions related to how characteristics of community programs and policies are associated with obesity-related outcomes among children.

    The influence of arbuscular mycorrhizal (AM) fungus Glomus mosseae on characteristics of the growth, water status, chlorophyll concentration, gas exchange, and chlorophyll fluorescence of maize plants under salt stress was studied in the greenhouse. Maize plants were grown in sand and soil mixture with five NaCl levels (0, 0.5, 1.0, 1.5, and 2.0 g/kg dry substrate) for 55 days, following 15 days of non-saline pretreatment. Under salt stress, mycorrhizal maize plants had higher dry weight of shoot and root, higher relative chlorophyll content, better water status (decreased water saturation deficit, increased water use efficiency, and relative water content), higher gas exchange capacity (increased photosynthetic rate, stomatal conductance and transpiration rate, and decreased intercellular CO(2) concentration), higher non-photochemistry efficiency [increased non-photochemical quenching values (NPQ)], and higher photochemistry efficiency [increased the maximum quantum yield in the dark-adapted state (Fv/Fm), the maximum quantum yield in the light-adapted sate (Fv'/Fm'), the actual quantum yield in the light-adapted steady state (phiPSII) and the photochemical quenching values (qP)], compared with non-mycorrhizal maize plants. In addition, AM symbiosis could trigger the regulation of the energy biturcation between photochemical and non-photochemical events reflected in the deexcitation rate constants (kN, kN', kP, and kP'). All the results show that G. mosseae alleviates the deleterious effect of salt stress on plant growth, through improving plant water status, chlorophyll concentration, and photosynthetic capacity, while the influence of AM symbiosis on photosynthetic capacity of maize plants can be indirectly affected by soil salinity and mycorrhizae-mediated enhancement of water status, but not by the mycorrhizae-mediated enhancement of chlorophyll concentration and plant biomass.

    Full Text Available Abstract Background The underlying mechanisms of overweight and obesity in adolescents are still not fully understood. The aim of this study was to investigate modifiable and non-modifiable correlates of weight status among 1103 Norwegian 11-year-old adolescents in the HEalth in Adolescents (HEIA study, including demographic factors such as gender and parental education, and behavioral factors such as intake of sugar-sweetened beverages, snacks and breakfast consumption, watching TV and playing computer games, physical activity and sedentary time. Methods Weight and height were measured objectively, body mass index (BMI was calculated and International Obesity Task Force cut-offs were used to define weight status. Physical activity and sedentary time were measured by accelerometers. Other behavioral correlates and pubertal status were self-reported by questionnaires. Parental education was reported by the parents on the consent form for their child. Associations were investigated using logistic regressions. Results There were gender differences in behavioral correlates of weight status but not for weight status itself. Adolescents with parents in the highest education category had a 46% reduced odds of being overweight compared to adolescents with parents in the lowest education category. Adolescents with parents with medium education had 42% lower odds of being overweight than adolescents with parents with the lowest education category. Level of parental education, breakfast consumption and moderate to vigorous physical activity were positively associated with being normal weight, and time watching TV was positively associated with being overweight for the total sample. Gender differences were detected; boys had a doubled risk of being overweight for every additional hour of watching TV per week, while for girls there was no association. Conclusions The present study showed a social gradient in weight status in 11-year-olds. Both breakfast

    Purpose Nearly 70% of adult Americans are overweight or obese, but the associations between physical activity, diet quality, and weight status have not been examined in a representative sample of U.S. adults. The purpose of this study was to examine the associations among moderate-to-vigorous physical activity (MVPA), diet quality, and weight status within and across age groups in U.S. adults. Methods Participants included 2,587 men and 2,412 women ages 20 to ≥70 years from the National Health and Nutrition Examination Survey (NHANES) 2003–2004 and 2005–2006. Physical activity was measured by accelerometry. Diet quality was assessed with overall Healthy Eating Index-2005 scores. Measures of weight status, BMI and waist circumference, were assessed using standard NHANES protocols. Results Across age groups, MVPA was lower in the older age groups for both men and women while diet quality was higher (P<.001). BMI and waist circumference were also higher in the older age groups (P<0.05). Within age groups, MVPA was inversely associated with BMI and waist circumference for men and women in nearly every age group (P<0.05). Diet quality was inversely associated with the weight status variables only in men ages 30–39, 40–49 (BMI only), and 50–59 years, and women ages 50–59 years (P<0.05). Conclusions We observed clear age-related trends for measures of weight status, physical activity, and diet quality in U.S. men and women. MVPA was very consistently related to weight status in both genders. The relationship between diet quality and weight status was less consistent. These findings provide support for public health efforts to prevent obesity by promoting increased physical activity in adult Americans. PMID:25058328

    Objective Recognising overweight and obesity is critical to prompting action, and consequently preventing and treating obesity. The present study examined the association between parental perceptions of child weight status and child’s diet. Methods Participants were members of the Gateshead Millennium Study. Parental perception of their child’s weight status was assessed using a questionnaire and compared against International Obesity Task Force cut-offs for childhood overweight and obesity when the children were aged 6–8 years old. Diet was assessed at age 6-8years old using the FAST (Food Assessment in Schools Tool) food diary method. The association between parental perception and dietary patterns as defined by Principal Components Analysis, was assessed using multivariate regression after adjustment for child’s gender, child’s weight status, maternal body mass index (BMI), maternal education and deprivation status. Results Of the 361 parents who provided complete data on confounders and on their perception of their child’s weight status, 63 (17%) parents perceived their child as being of ‘normal’ weight or ‘overweight’ when they were actually ‘overweight’ or ‘obese’, respectively. After adjustment for confounders, parents who misperceived their child’s weight had children with a lower ‘healthy’ dietary pattern score compared to children whose parents correctly perceived their weight (β = -0.88; 95% CI: -1.7, -0.1; P-value = 0.028). This association was found despite higher consumption of reduced sugar carbonated drinks amongst children whose parents incorrectly perceived their weight status compared to children whose parents perceived their weight correctly (52.4% vs. 33.6%; P-value = 0.005). Conclusions In conclusion, children whose parents did not correctly perceive their weight status scored lower on the ‘healthy’ dietary pattern. Further research is required to define parents’ diets based on their perception status

    The current study aimed to determine gender differences in nutritional habits, eating behaviour, weight status, body image and weight control practices during early and late adolescence. 677 Viennese pupils (253 boys and 424 girls) between the ages 10 and 18 years (x = 14.1 yrs; +/- 2.2) were enrolled in the study. Weight status was determined by means of body mass index percentiles. To assess eating behavior, food preferences, body image and weight control practices, a 48 item questionnaire was developed. Significant gender differences in weight status were observable during late adolescence only. Girls are significantly less satisfied with their body weight. Furthermore, girls practice dieting and weight control to avoid any weight gain more frequently than boys. Gender differences in eating behavior intensified from early to late adolescence. From early to late adolescence, meal size decreased among girls, while it remains stabile or increased among boys. Boys eat generally more than girls. Furthermore, boys preferred meat and fast food while girls consumed fruits, vegetables and healthy food significantly more frequently. These gender differences are explained by gender specific energetic demands and culture typical beauty ideals.

    Konjac glucomannan (KGM) is a natural polysaccharide of β(1-4)-D-glucomannopyranosyl backbone of D-mannose and D-glucose derived from the tuber of Amorphophallus konjac C. Koch. KGM has been reported to have a wide range of activities including wound healing. In this study we examined KGM extracts prepared from five plant species, (Amorphophallus konjac Koch, Amorphophallus oncophyllus, Amorphophallus prainii, Amorphophallus paeoniifolius and Amorphophallus elegans) for their effects on cultured human keratinocytes and fibroblasts. Extracts from A. konjac Koch, A. oncophyllus and A. prainii (but not from A. paeoniifolius or A. elegans) stimulated fibroblast proliferation both in the absence and presence of serum. However, these materials inhibited keratinocyte proliferation. The fibroblast stimulatory activity was associated with high molecular weight fractions of KGM and was lost following ethanol extraction or enzyme digestion with β-mannanase. It was also reduced by the addition of concanavalin A but not mannose suggesting that these heteropolysaccharides are acting on lectins but not via receptors specific to mannose. The most dramatic effect of KGM was seen in its ability to support fibroblasts for 3weeks under conditions of deliberate media starvation. This effect did not extend to supporting keratinocytes under conditions of media starvation but KGM did significantly help support adipose derived stem cells under media starvation conditions.

    Fast food restaurants have become widespread in both developed and developing countries due to nutritional and economic transitions. The frequency of fast food intake is relatively high among adolescents; however, fast food consumption is positively associated with total energy intake and obesity in adolescents. This study aimed to examine the perception of Jordanian adolescents towards fast foods relative to gender and obesity. A cross-sectional survey was conducted on 400 boys and 395 girls, aged 15-18 years. The adolescents completed a validated questionnaire to measure the perception of adolescents towards fast foods during the year 2013-2014. Weight and height were measured. Numbers who were non-overweight, overweight, and obese were calculated for each age and sex using the International Obesity Task Force (IOTF) standard. The majority of participants perceived foods which are eaten as sandwiches as fast foods. A significant difference between boy and girl adolescents was reported regarding perception of French fries ( p fast foods. Girls were significantly more enthusiastic than boys to consider cuscusi plate ( p foods ( p foods ( p foods ( p foods ( p fast foods. The difference between obese and non-obese regarding the perception of fast foods was only significant among boy participants. Western or non-Arab foods, food prepared fast and eaten fast in self-service outlets, and food rich in calories were significantly perceived as fast food by Jordanian adolescents ( p perception of foods as fast foods or non-fast foods was significantly different between both genders as well as in obese and non-obese male Jordanian adolescents.

    Parental feeding style, as measured by the Child Feeding Questionnaire (CFQ), may be an important influence on child feeding behaviour and weight status in early to mid childhood, but more evidence on parental feeding style is required from samples outside the USA. We aimed to use the CFQ in a sample of 117 Scottish children (boys n 53, girls n 64 mean age 4.6 (SD 0.5) years) to: characterise gender differences and changes over time (in forty of the 117 children studied over 2 years); test associations between parental feeding style, free-living energy intake (measured over 3 days using the multiple pass 24-h recall), and weight status (BMI SD score). No dimensions of parental feeding style changed significantly over 2 years in the longitudinal study (P>0.05 in all cases). No aspects of parental feeding style as measured by the CFQ differed significantly between the sexes (P>0.05 in all cases). Parental perceptions of child weight status were generally significantly positively correlated with child weight status as measured by the BMI SD score. In this sample and setting, measures of parental control over child feeding were generally not associated with child energy intake or weight status.

    Patients with gastrointestinal cancers are susceptible to nutritional deterioration which may be compounded by radiotherapy treatment toxicities. This study aimed to determine whether nutritional status at radiotherapy commencement or changes in nutritional status throughout radiotherapy were associated with treatment toxicity and outcomes in gastrointestinal cancer patients. Seventy-three gastrointestinal cancer patients receiving curative radiotherapy underwent medical record audits assessing body weight, radiotherapy toxicity, unplanned treatment breaks or hospital admissions and completion of prescribed treatment/s. Nutritional status was assessed in a subset of patients (n = 11) using the Patient-Generated Subjective Global Assessment tool. Seventy-five percent of patients lost weight throughout radiotherapy. Weight loss was significantly greater in patients experiencing unplanned radiotherapy breaks (-3.1% vs -1.6%, p nutritional status during radiotherapy (as measured by weight loss) may be associated with poorer short-term treatment outcomes in gastrointestinal cancer patients. Patient numbers were too small to definitively determine the effect of nutritional status at radiotherapy commencement or changes in nutritional status throughout radiotherapy (defined by PG-SGA) on treatment outcomes. Further research is required to investigate this in larger, longer-term studies. Copyright © 2010. Published by Elsevier Ltd.

    Drought is a major constraint for rice production in the rainfed lowlands in China. Silicon (Si) has been verified to play an important role in enhancing plant resistance to environmental stress. Two near-isogenic lines of rice (Oryza sativa L.), w-14 (drought susceptible) and w-20 (drought resistant), were selected to study the effects of exogenous Si application on the physiological traits and nutritional status of rice under drought stress. In wet conditions, Si supply had no effects on growth and physiological parameters of rice plants. Drought stress was found to reduce dry weight, root traits, water potential, photosynthetic parameters, basal quantum yield (F(v)/F(0)), and maximum quantum efficiency of PSII photochemistry (F(v)/F(m)) in rice plants, while Si application significantly increased photosynthetic rate (Pr), transpiration rate (Tr), F(v)/F(0), and F(v)/F(m) of rice plants under drought stress. In addition, water stress increased K, Na, Ca, Mg, Fe content of rice plants, but Si treatment significantly reduced these nutrient level. These results suggested that silicon application was useful to increase drought resistance of rice through the enhancement of photochemical efficiency and adjustment of the mineral nutrient absorption in rice plants.

It is unclear whether similar misperception exists in Asian populations. This study aimed to evaluate the ability of Singaporean mothers to accurately describe their three-year-old child's weight status verbally and visually.At three years post-delivery, weight and height of the children were measured. Body mass index (BMI was calculated and converted into actual weight status using International Obesity Task Force criteria. The mothers were blinded to their child's measurements and asked to verbally and visually describe what they perceived was their child's actual weight status. Agreement between actual and described weight status was assessed using Cohen's Kappa statistic (κ.Of 1237 recruited participants, 66.4% (n = 821 with complete data on mothers' verbal and visual perceptions and children's anthropometric measurements were analysed. Nearly thirty percent of the mothers were unable to describe their child's weight status accurately. In verbal description, 17.9% under-estimated and 11.8% over-estimated their child's weight status. In visual description, 10.4% under-estimated and 19.6% over-estimated their child's weight status. Many mothers of underweight children over-estimated (verbal 51.6%; visual 88.8%, and many mothers of overweight and obese children under-estimated (verbal 82.6%; visual 73.9%, their child's weight status. In contrast, significantly fewer mothers of normal-weight children were inaccurate (verbal 16.8%; visual 8.8%. Birth order (p<0.001, maternal (p = 0.004 and child's weight status (p<0.001 were associated with consistently inaccurate verbal and visual descriptions.Singaporean mothers, especially those of underweight and overweight children, may not be able to perceive their young child's weight status accurately.

    Full Text Available Introduction: Infants with low birth weights are provided with hospital nutrition support to enhance their survivability and body weights. However, different hospitals have different nutrition support formulas. Therefore, the effectiveness of these nutrition support formulas should be investigated. Objective: To assess the effect of hospital nutrition support on growth velocity and nutritional status of low birth weight infants at Al-Noor hospital, Saudi Arabia. Methods: A cross-sectional study was conducted between October, 2010 and December, 2012. Three hundred newborns were recruited from Al-Noor Hospital in Makkah city, Saudi Arabia. Infants were selected according to their birth weights and were divided equally into three groups; (i Low Birth Weight (LBW infants (15012500 g birth weight, (ii Very Low Birth Weight (VLBW infants (1001-1500 g birth weight and (iii Extremely Low Birth Weight (ELBW infants ( 0.05 were observed among groups. Serum calcium, phosphorus and potassium levels at discharge were higher (p < 0.05 than that at birth for ELBW and VLBW groups; while sodium level decreased in ELBW group to be within normal ranges. Albumin level was improved (p < 0.05 in ELBW group. Conclusion: Health care management for low birth weight infants in Al-Noor Hospital was not sufficient to achieve normal growth rate for low birth weight infants, while biochemical indicators were remarkably improved in all groups.

    Full Text Available Objectives. To examine if distinct characteristics are associated with parental misclassification of underweight (UW, normal weight (NW, and overweight or obese (OWOB children and the implications of misclassification on the parental evaluation of the child's lifestyle habits. Methods. Cross-sectional analysis (2004 sample of the Quebec Longitudinal Study of Child Development (1998–2010 (n=1,125. Results. 16%, 55%, and 77% of NW, UW and OWOB children were perceived inaccurately, respectively. Misperception was significantly higher in nonimmigrant parents of UW children, in highly educated parents of NW children and in NW and OWOB children with lower BMI percentiles. Erroneous body weight status identification impedes the evaluation of eating habits of all children as well as physical activity and fitness levels of UW and OWOB children. Conclusion. Parental misclassification of the child's body weight status and lifestyle habits constitutes an unfavorable context for healthy body weight management.

    Childhood obesity prevention practice guidelines recommend that parents encourage the intake of certain types of foods and discourage the intake of others. It is unknown if parents of children of different weight statuses encourage or discourage their child's intake differently based on food type. The objective of this study was to determine the association of child weight status with maternal encouragement and discouragement of for four different types of food. A total of 222 mother-child dyads were video-taped during the standardized, sequential presentation of four foods to both participants: cupcakes (familiar dessert), green beans (familiar vegetable), halva (unfamiliar dessert) and artichoke (unfamiliar vegetable). Mother's encouragements and discouragements of child intake were reliably coded for each food type. Poisson regression models were used to test the independent association of child weight status (normal weight, overweight and obese) with encouragement and discouragement for each food type. Mothers of an obese, vs. normal or overweight child, had lower rates of encouragement for a familiar dessert (p = 0.02), and a higher rates of discouragements for a familiar dessert (p = 0.001), a familiar vegetable (p = 0.01), and an unfamiliar vegetable (p = 0.001). There were no differences in encouragements or discouragements between mothers of an overweight, vs. obese child, for any of the 4 food types. Mothers of obese children may alter their feeding behavior differentially based on food type. Future work should examine how interventions promoting maternal encouragement or discouragement of different food types impact child weight status.

    The aim of this study was to examine whether child-caregivers', both parents and kindergarten teachers, health parameters (age, weight status, habitual physical activity score) are significantly associated with the risk of overweight in young children. We assessed the individual body mass index standard deviation score in a regional cross-sectional health study and matched a representative sample of 434 kindergartners aged 3 to 6-years with their caregivers' weight and habitual physical activity status. Furthermore, we identified factors associated with the general ability of child-caregivers to identify overweight in children, and the awareness to classify a child within the correct weight category. Our study confirmed most of the known associations between parental anthropometrics and psychosocial factors with childhood overweight and obesity. A significantly higher proportion of boys tended to be overweight or obese (p = 0.027) and parents were more likely to misclassified boys overweight as normal weight (OR: 1.86; 95% CI 1.21-2.86). Adjusted for confounders, logistic regression analysis revealed that kindergarten teachers' weight status (OR: 1.97; 95%-CI: 1.01-3.83) and habitual physical activity scores (OR: 2.32; 95%-CI: 1.10-4.92) were associated with children's weight status. Kindergarten teachers' weight and habitual physical activity score seem to be new independent risk factors for overweight in kindergartners 3 to 6-years of age. Our results suggest that the psychosocial, non-genetic association of non-parental child-caregivers on children's weight is relatively high and that the association of non-parental child-caregivers warrants further investigation.

    Introduction Pain reports are greater with increasing weight status, and exercise can reduce pain perception. It is unknown however, whether exercise can relieve pain in adolescents of varying weight status. The purpose of this study was to determine if adolescents across weight status report pain relief following high intensity aerobic exercise (exercise-induced hypoalgesia [EIH]). Methods 62 adolescents (15.1±1.8 years, 29 males) participated in three sessions: 1) Pressure pain thresholds (PPTs) before and after quiet rest, clinical pain (McGill Pain Questionnaire), and physical activity levels (self-report and ActiSleep Plus Monitors) were measured; 2) PPTs were measured with a computerized algometer at the 4th finger nailbed, middle deltoid muscle, and quadriceps muscle before and after maximal oxygen uptake test (VO2 max Bruce Treadmill Protocol); and 3) Body composition was measured with Dual-energy X-ray absorptiometry. Results All adolescents met criteria for VO2 max. Based on body mass index z-score, adolescents were categorized as normal weight (n=33) or overweight/obese (n=29). PPTs increased following exercise (EIH) and were unchanged with quiet rest (trial × session: p=0.02). EIH was similar across the 3 sites and between normal weight and overweight/obese adolescents. Physical activity and clinical pain were not correlated with EIH. Overweight/obese adolescents had similar absolute VO2 max (L·min-1) but lower relative VO2 max (ml·kg-1·min-1) compared with normal weight adolescents. When adolescents were categorized using FitnessGram standards as unfit (n=15) and fit (n=46), the EIH response was similar between fitness levels. Conclusion This study is the first to establish that adolescents experience EIH in both overweight and normal weight youth. EIH after high intensity aerobic exercise was robust in adolescents regardless of weight status and not influenced by physical fitness. PMID:25856681

    Full Text Available Abstract Background Adolescent weight status is a cumulative effect of health and nutritional problems. Adolescent weight problems often go unnoticed as weight assessment is not considered a priority in adolescents. Objectives To determine the weight status of adolescents using BMI and to identify the contributing factors to adolescent weight problems. Methods In April 2010, 960 adolescents aged 10–19 years in secondary schools in Port Harcourt were selected for the study using a stratified multi-staged sampling method. Structured questionnaires were filled by the investigators while weight and height were measured. BMI was calculated using the formula weight/height2 (kg/m2. Results The prevalence of underweight, overweight, obesity and stunting were 6.4%, 6.3%, 1.8% and 5.4% respectively. Factors which were commoner in overweight adolescents were high socioeconomic class, higher maternal education, spending > 3 hours a day watching television and frequent ingestion of snacks. Conclusion There is a need for periodic weight assessment of adolescents and health education to promote healthy eating habits and regular physical exercise as part of the School Health Programme.

    This study sought to assess differences in attraction to physical activity, perceived physical competence and parental socialization influences across gender, body mass index and socioeconomic status in Portuguese children. Cross-sectional study. 683 children, aged 8-10 years, from elementary schools were participants. Attraction to physical activity, perceived physical competence, parental socialization influences and socioeconomic status were assessed via standardized questionnaires. The prevalence of overweight and obesity was calculated using body mass index, based on the international cut-off points. MANOVA and ANOVA models were conducted. Boys reported greater enjoyment of games and sports participation than did girls. Boys and normal-weight children perceived themselves as being more successful and physically competent than did girls and obese children. Normal-weight girls enjoyed participation in vigorous physical activity more than did overweight and obese girls. Obese children felt less accepted by their peers in games and sports than did normal-weight and overweight children. High and medium socioeconomic status children perceived physical activity participation as of greater importance than did low-socioeconomic status children. High-socioeconomic status girls reported greater liking of the exertional aspects of physical activity compared to low socioeconomic status girls. High socioeconomic status children were more likely to perceive their parents as positive role models and perceived that they had greater enjoyment of physical activity than did lower socioeconomic status children. These results suggest that physical activity promotion interventions should focus on girls, obese children and lower socioeconomic status children as these individuals tend to have lower levels of attraction to physical activity, lower perceived physical competence and less parent physical activity support, which puts them at greater risk of being physically inactive

This retrospective studyaims to determine the relationship between maternal nutritional status (pre-pregnancy body mass index (BMI and weight gain during pregnancy and infant’s birth weight among vegetarians in Jakarta. The total sample of 85 children aged 1 month to 5 years was selected purposively. Results showed that the mean of pre-pregnancy BMI of vegetarian mothers is 20.2 kg/m2 (±2.2 kg/m2, pregnancy weight gain is 15.5 kg (±6.4 kg and infant’s birth weight is 3212 gs (±417.7 gs. Pre-pregnancy BMI and pregnancy weight gain were significantly associated with infant’s birth weight of vegetarians. There is no relationship between pre-pregnancy BMI and pregnancy weight gain. Multivariate analysis found that pre-pregnancy BMI, protein, vitamin B12, iron, and Zn intakes and sex has relationship with infant’s birthweight. It is recommended that vegetarian mothers should get information about the importance of pre-pregnancy nutrition, optimal pregnancy weight gain, and maintaining adequate intake of protein, vitamin B12, iron, and Zn during pregnancy

    The prevalence of overweight and obesity among children is on the rise worldwide. Prior studies find that parents' child-feeding practices are associated with child weight status and the efficacy of specific parental child-feeding practices can be moderated by parenting styles. In the current longitudinal study, we examined the associations between child-feeding practices and weight status changes over 1 year among a sample of school-aged children in Taiwan. In autumn 2008, a child-feeding questionnaire and parenting-style questionnaire were administered to parents of the second and fourth graders in an elementary school in Taiwan. The weight and height of the students were measured by a trained school nurse in 2008 and again in 2009. An elementary school in central Taiwan. A total of 465 parent-child pairs were included in the analysis. Using a gender- and age-adjusted BMI classification scheme issued by the Taiwan Department of Health, 29·2 % of the students were considered overweight at the 2009 measurement. Controlling for 2008 weight status revealed moderating effects of parenting style on the relationship between child-feeding practices and child weight status. Both authoritative and authoritarian mothers might monitor their children's dietary intake; however, the effectiveness of this practice was better, in terms of weight status control, among the authoritative mothers. Findings suggest that parenting styles have a moderating effect on specific parental child-feeding practices. Parenting styles and parent's feeding practices could be an important focus for future public health interventions addressing the rising childhood obesity epidemic.

    Full Text Available Abstract Background Childhood obesity is a continuing problem in the UK and South Asian children represent a group that are particularly vulnerable to its health consequences. The relationship between body dissatisfaction and obesity is well documented in older children and adults, but is less clear in young children, particularly South Asians. A better understanding of this relationship in young South Asian children will inform the design and delivery of obesity intervention programmes. The aim of this study is to describe body image size perception and dissatisfaction, and their relationship to weight status in primary school aged UK South Asian children. Methods Objective measures of height and weight were undertaken on 574 predominantly South Asian children aged 5-7 (296 boys and 278 girls. BMI z-scores, and weight status (underweight, healthy weight, overweight or obese were calculated based on the UK 1990 BMI reference charts. Figure rating scales were used to assess perceived body image size (asking children to identify their perceived body size and dissatisfaction (difference between perceived current and ideal body size. The relationship between these and weight status were examined using multivariate analyses. Results Perceived body image size was positively associated with weight status (partial regression coefficient for overweight/obese vs. non-overweight/obese was 0.63 (95% CI 0.26-0.99 and for BMI z-score was 0.21 (95% CI 0.10-0.31, adjusted for sex, age and ethnicity. Body dissatisfaction was also associated with weight status, with overweight and obese children more likely to select thinner ideal body size than healthy weight children (adjusted partial regression coefficient for overweight/obese vs. non-overweight/obese was 1.47 (95% CI 0.99-1.96 and for BMI z-score was 0.54 (95% CI 0.40-0.67. Conclusions Awareness of body image size and increasing body dissatisfaction with higher weight status is established at a young age in

    Allergic disease is multifactorial in origin. Because iron nutrition affects immune responses and maternal pregnancy weight gain impairs fetal iron delivery while increasing fetal demands for growth, the study examined maternal pregnancy weight gain, newborn iron status and an index of atopic disease, infant eosinophilia. Within a larger prospective study of healthy newborns at risk for developing iron deficiency anemia, umbilical cord iron indicators were compared to infant eosinophil counts. Infants who developed eosinophilia exhibited higher cord reticulocyte-enriched zinc protoporphyrin/heme ratio, Peosinophilia was 90%. High maternal pregnancy weight gain predicted infant eosinophil counts, Peosinophilia, Peosinophilia.

    Full Text Available Abstract Background Associations between hours worked per week and Body Mass Index (BMI, food intake, physical activity, and perceptions of eating healthy at work were examined in a sample of transit workers. Methods Survey data were collected from 1086 transit workers. Participants reported hours worked per week, food choices, leisure-time physical activity and perceptions of the work environment with regard to healthy eating. Height and weight were measured for each participant. Multivariate linear and logistic regressions were conducted to examine associations between work hours and behavioral variables. Associations were examined in the full sample and stratified by gender. Results Transit workers working in the highest work hour categories had higher BMI and poorer dietary habits, with results differing by gender. Working 50 or more hours per week was associated with higher BMI among men but not women. Additionally, working 50 or more hours per week was significantly associated with higher frequency of accessing cold beverage, cold food, and snack vending machines among men. Working 40 or more hours per week was associated with higher frequency of accessing cold food vending machines among women. Reported frequency of fruit and vegetable intake was highest among women working 50 or more hours per week. Intake of sweets, sugar sweetened beverages, and fast food did not vary with work hours in men or women. Physical activity and perception of ease of eating healthy at work were not associated with work hours in men or women. Conclusions Long work hours were associated with more frequent use of garage vending machines and higher BMI in transit workers, with associations found primarily among men. Long work hours may increase dependence upon food availability at the worksite, which highlights the importance of availability of healthy food choices.

    Full Text Available Psychological disorders in people with extreme weight (low weight or obesity should be taken into consideration by health professionals in order to practice an effective treatment to these patients. This study evaluates the association between body mass index (BMI and psychological distress in 563 inhabitants of Málaga (South of Spain. Participants were classified in four categories of BMI: Underweight (BMI <18.5 Kg/m2, Normal weight (BMI 18.5–24.99 Kg/m2, Overweight (BMI 25.0–29.99 Kg/m2 and Obesity (BMI >30 Kg/m2. Psychological distress was measured with the Spanish version of the Derogatis’ Symptoms Checklist Revised (SCL-90-R. We observed a symmetric U-shaped relationship between weight status and psychological distress in all SCL-90-R dimensions (p for quadratic trend <0.001 for both men and women. Participants with extreme weight showed the worst psychological status, and participants with normal weight exhibited the best. We found no statistically significant differences between underweight and obese participants in 9 of the 10 SCL-90-R dimensions analyzed among men, and in 8 of the 10 dimensions among women. Underweight and obese participants showed no gender differences in psychological distress levels. Psychological treatment of Mediterranean people with extreme weight, should consider underweight and obese patients at the same level of psychological distress.

    OBJECTIVE: To analyze maternal conceptions about excess weight in infancy and the nutritional status of their preschool-aged children. METHODS: A mixed, exploratory study was performed using semi-structured interviews. Two study groups were defined: a group of 16 mothers of children with excess weight and a group of 15 mothers of eutrophic children. The interviews were submitted to content analysis using CHIC software (Classification Hiérarchique Implicative et Cohésitive®). RESULTS: The mothers of children with excess weight tended to conceive thin children as malnourished, while those of normal weight children emphasized the influence of family and genetics as determinants of a child’s nutritional status. Although there was a certain consensus among the mothers that an unhealthy diet contributes to the risk of a child developing excess weight, the concept of genetics as a determinant of a child’s nutritional status was also present in the dialogue from the mothers of both groups. This result indicates a lack of clarity regarding the influence of eating behavior and family lifestyle on weight gain and the formation of a child’s eating habits. Both groups indicated that the mother has a decisive role in the eating habits of her child; however, the mothers of children with excess weight did not seem to take ownership of this concept when addressing the care of their own children. CONCLUSION: Differences in conceptions, including taking ownership of care, may contribute to the development of excess weight in preschool-aged children. PMID:27652830

    Full Text Available Background and aims. The aim of the study is to evaluate fluid intake during adolescence and correlate it with weight status. Material and methods. We assessed fluid intake using a validated questionnaire in a group of 106 adolescent students (22 boys - 20.8%, aged 15-19 years. Weight status was evaluated with the BMI-for-age values,using growth normograms. Results. There were no statistically significant differences in the frequency of water intake between sexes (p>0.05. Water intake at least 3 times a day was declared by 72.16% of normal weight students and in 66% of overweight and obese, the difference being statistically significant (p=0.003. Boys consumed larger amounts of water (p=0.042 than girls. Intake of 100% natural fruit juice was significantly higher in boys compared to girls (p=0.002. A significantly higher percentage of normal weight adolescents consumed≤500 mL/day non-carbonated (p=0.004 and carbonated (p<0.001 sugar-sweetened beverages compared to the overweight or obese, who consumed ≥500 mL/day. Conclusions. The quantitative and qualitative assessment of fluid intake among adolescents is a mandatory step in the assessment of calorie and nutritional intake. Promoting low-calorie fluid intake in this age group, along with the principles of healthy eating, could contribute to achieving an optimal weight status.

    Full Text Available BACKGROUND: Few studies have examined parent-child resemblance in body weight status using nationally representative data for the US. DESIGN: We analyzed Body Mass Index (BMI, weight status, and related correlates for 4,846 boys, 4,725 girls, and their parents based on US nationally representative data from the 2006 and 2007 Medical Expenditure Panel Survey (MEPS. Pearson partial correlation coefficients, percent agreement, weighted kappa coefficients, and binary and multinomial logistic regression were used to examine parent-child resemblance, adjusted for complex sampling design. RESULTS: Pearson partial correlation coefficients between parent and child's BMI measures were 0.15 for father-son pairs, 0.17 for father-daughter pairs, 0.20 for mother-son pairs, and 0.23 for mother-daughter pairs. The weighted kappa coefficients between BMI quintiles of parent and child ranged from -0.02 to 0.25. Odds ratio analyses found children were 2.1 (95% confidence interval (CI: 1.6, 2.8 times more likely to be obese if only their father was obese, 1.9 (95% CI: 1.5, 2.4 times more likely if only their mother was obese, and 3.2 (95% CI: 2.5, 4.2 times more likely if both parents were obese. CONCLUSIONS: Parent-child resemblance in BMI appears weak and may vary across parent-child dyad types in the US population. However, parental obesity status is associated with children's obesity status. Use of different measures of parent-child resemblance in body weight status can lead to different conclusions.

    The Earned Value Management System (EVMS) method integrates three critical elements of project management scope, cost and time management. It requires the periodic monitoring of actual expenditures and physical scope accomplishments and allows calculation of cost and schedule variances along with performance indices. It allows for casting of project cost and schedule at completion and highlights the possible need for corrective action. It is anticipated that there will be intense competition in the nuclear industry as the cost and time for nuclear power plant construction. In order to attain competitive advantages, utilizing advanced project control systems by integrating cost and time management is of great concern for practitioners. This paper is to review the status of EVMS and its effective implementation to nuclear power plant construction.

    Objective: To analyze the status of postpartum weight retention and its associated factors among Chinese lactating women in 2013. Methods: This study was based on the databank of Chinese National Nutrition and Health Surveillance in 2013. Using the multi-stage stratified cluster sampling method, we enrolled 12 514 women, at 0-24 months postpartum, from 55 sites in 30 provinces of China (excluding the Tibet Autonomous Region). Questionnaires were used to collect data on basic characteristics, physical activity, lifestyle, food intake, pre-pregnancy weight, weight before delivery, disease history during pregnancy, delivery date, delivery mode, parity and breastfeeding information. Current body weight and height of each subject were measured. Postpartum weight retention in each subject was calculated as the difference between pre-pregnancy and current weights. High postpartum weight retention was defined as ≥5 kg. Survey sample weights were calculated according to the sampling design and number of children under 2 years old from 2010 population census data of China. Associated factors of high postpartum weight retention were identified by multiple logistic regression analysis. Results: A total of 9 972 women were included in this study. P50 (P25-P75) of weight retention for participants was 3.6 (0.2-7.3) kg and high weight retention accounted for 41.5% of the subjects (4 134/9 972). The weighted means (SE) of weight retention was 3.5 (0.1) kg, and it was at 0 to <3, 3 to <6, 6 to <9, 9 to <12, 12 to <18 and 18 to <24 months postpartum were 5.3 (0.2), 4.5 (0.2), 3.8 (0.2), 3.1 (0.2), 2.8 (0.2) and 3.0 (0.2) kg, respectively. The weighted proportion of high postpartum weight retention was 37.4% (95%CI: 36.0%-38.9%). Compared with women aged under 25 years old, the odds ratio of high postpartum weight retention was 1.31 for women over 30 years old. Compared with women at 18 to <24 months postpartum, the odds ratio of high postpartum weight retention was 2.67, 1.61 and

    Full Text Available Abstract Background Few studies have examined the association between weight perception and socioeconomic status (SES in sub-Saharan Africa, and none made this association based on education, occupation and income simultaneously. Methods Based on a population-based survey (n = 1255 in the Seychelles, weight and height were measured and self-perception of one's own body weight, education, occupation, and income were assessed by a questionnaire. Individuals were considered to have appropriate weight perception when their self-perceived weight matched their actual body weight. Results The prevalence of overweight and obesity was 35% and 28%, respectively. Multivariate analysis among overweight/obese persons showed that appropriate weight perception was directly associated with actual weight, education, occupation and income, and that it was more frequent among women than among men. In a model using all three SES indicators together, only education (OR = 2.5; 95% CI: 1.3-4.8 and occupation (OR = 2.3; 95% CI: 1.2-4.5 were independently associated with appropriate perception of being overweight. The OR reached 6.9 [95% CI: 3.4-14.1] when comparing the highest vs. lowest categories of SES based on a score including all SES indicators and 6.1 [95% CI: 3.0-12.1] for a score based on education and occupation. Conclusions Appropriately perceiving one's weight as too high was associated with different SES indicators, female sex and being actually overweight. These findings suggest means and targets for clinical and population-based interventions for weight control. Further studies should examine whether these differences in weight perception underlie differences in cognitive skills, healthy weight norms, or body size ideals.

    OBJECTIVE. To investigate the effects of weight status, food type and exposure to food and non-food advertisements on children's preference for branded and non-branded foods. DESIGN. A within-subjects, counterbalanced design with control (toy advertisement) and experimental (food advertisement) conditions. Subjects. A total of 37 school students (age: 11-13 years; weight status: 24 lean, 10 overweight, 3 obese). Measurements. Advertisement recall list, two food preference measures; the Leeds Food Preference Measure (LFPM), the Adapted Food Preference Measure (AFPM) and a food choice measure; the Leeds Forced-choice Test (LFCT). RESULTS. Normal weight children selected more branded and non-branded food items after exposure to food advertisements than in the control (toy advertisement) condition. Obese and overweight children showed a greater preference for branded foods than normal weight children per se, and also in this group only, there was a significant correlation between food advertisement recall and the total number of food items chosen in the experimental (food advertisement) condition. CONCLUSION. Exposure to food advertisements increased the preference for branded food items in the normal weight children. This suggests that television food advertisement exposure can produce the same 'obesigenic' food preference response found in overweight and obese children in their normal weight counterparts.

    AIM: We investigated the relationship between taste sensitivity, nutritional status and metabolic syndrome and possible implications on weight loss dietary program. METHODS: Sensitivity for bitter, sweet, salty and sour tastes was assessed by the three-Alternative-Forced-Choice method in 41 overweight (OW), 52 obese (OB) patients and 56 normal-weight matched controls. OW and OB were assessed also for body composition (by impedence), resting energy expenditure (by indirect calorimetry) and presence of metabolic syndrome (MetS) and were prescribed a weight loss diet. Compliance to the weight loss dietary program was defined as adherence to control visits and weight loss ≥ 5% in 3 mo. RESULTS: Sex and age-adjusted multiple regression models revealed a significant association between body mass index (BMI) and both sour taste (P nutritional (OW and OB) or metabolic status (MetS+ and MetS-). CONCLUSION: There is no cause-effect relationship between overweight and metabolic derangements. Taste thresholds assessment is not useful in predicting the outcome of a diet-induced weight loss program. PMID:25317249

    Full Text Available Background: Weight is one of the most important parameters in assessing nutritional status. However, weight can be difficult to measure in elderly people who are unable to stand. Chumlea et al. created two equations to estimate weight in non-ambulatory patients using readily available body measurements. Objective: The aim of the study is to analyze the usefulness of Chumlea's equations in assessing nutritional status of elderly hospitalized patients. Methods: We measured weight, height, arm and calf circumference, subscapular skinfold and knee height of 82 hospitalized elderly patients, all of whom were able to stand. Estimated weight (EW was obtained by Chumlea's equations. Body mass index (BMI and Mini Nutritional Assessment test (MNA were calculated using actual weight and EW. Bland-Altmann analysis and intraclass correlation coefficient (ICC between real and estimated parameters were assessed. Results: We found a statistically significant ICC between actual weight and EW (r = 0.926, real BMI and estimated BMI (r = 0.910 and real MNA and estimated MNA (r = 0.982 (P < 0.001. Chumlea's equations, however, underestimated weight: 54.05 (DS 11.88 vs 61.46 (DS 13.08; BMI: 22.30 (DS 4.61 vs 25.36 (DS 5.17 and MNA: 22.73 (DS 4.43 vs 23.30 (DS 4.33 (P<0.001. In spite of this underestimation, estimated MNA detected 100% of patients malnourished and 96% of those at risk of malnutrition. Conclusions: Results obtained by Chumlea's equations showed a good ICC with actual body weight and real BMI and MNA, but values were underestimated. These equations can be useful to detect undernourished hospitalized elderly patients.

    The availability of many genomic resources such as genome sequences, functional genomics resources including microarrays and RNA-seq, sufficient numbers of molecular markers, express sequence tags (ESTs) and high-density genetic maps is causing a rapid acceleration of genetics and genomic research of many fruit plants. This is leading to an increase in our knowledge of the genes that are linked to many horticultural and agronomically important traits. Recently, some progress has also been made on the identification and functional analysis of miRNAs in some fruit plants. This is one of the most active research fields in plant sciences. The last decade has witnessed development of genomic resources in many fruit plants such as apple, banana, citrus, grapes, papaya, pears, strawberry etc.; however, many of them are still not being exploited. Furthermore, owing to lack of resources, infrastructure and research facilities in many lesser-developed countries, development of genomic resources in many underutilized or less-studied fruit crops, which grow in these countries, is limited. Thus, research emphasis should be given to those fruit crops for which genomic resources are relatively scarce. The development of genomic databases of these less-studied fruit crops will enable biotechnologists to identify target genes that underlie key horticultural and agronomical traits. This review presents an overview of the current status of the development of genomic resources in fruit plants with the main emphasis being on genome sequencing, EST resources, functional genomics resources including microarray and RNA-seq, identification of quantitative trait loci and construction of genetic maps as well as efforts made on the identification and functional analysis of miRNAs in fruit plants.

    Research regarding the association between food insecurity and weight status among youth has produced mixed results. However, few studies on this topic have utilized data that includes survey responses from children themselves regarding their experience with food insecurity. This study was undertaken to examine the association between food insecurity and weight status among youth, as well as the potential mediation by psychosocial factors. A survey of 5th-7th grade students was administered to gather information on food insecurity, social and psychological resources, and health. The primary analysis includes OLS (Ordinary Least Squares) regression conducted using SPSS software and Sobel's test for mediation. Results suggest a positive association between food insecurity and weight status even when controlling for key demographic variables. In addition, we find that this association is mediated by psychosocial factors-namely, perceived social status and depression. Insights from this work highlight the need to consider non-nutritional pathways through which food insecurity impacts health as well the need to continue surveying youth directly when examining their experiences with food insecurity.

    Full Text Available Few studies are focused on the antioxidant status and its changes in anorexia nervosa (AN. Based on the hypothesis that renutrition improves that status, the aim was to determine the plasma antioxidant status and the antioxidant enzymes activity at the beginning of a personalized nutritional program (T0 and after recovering normal body mass index (BMI (T1. The relationship between changes in BMI and biochemical parameters was determined. Nutritional intake, body composition, anthropometric, hematological and biochemical parameters were studied in 25 women with AN (19.20 ± 6.07 years. Plasma antioxidant capacity and antioxidant enzymes activity were measured. Mean time to recover normal weight was 4.1 ± 2.44 months. Energy, macronutrients and micronutrients intake improved. Catalase activity was significantly modified after dietary intake improvement and weight recovery (T0 = 25.04 ± 1.97 vs. T1 = 35.54 ± 2.60μmol/min/mL; p < 0.01. Total antioxidant capacity increased significantly after gaining weight (T0 = 1033.03 ± 34.38 vs. T1 = 1504.61 ± 99.73 μmol/L; p < 0.01. Superoxide dismutase activity decreased (p < 0.05 and glutathione peroxidase did not change. Our results support an association between nutrition improvement and weight gain in patients with AN, followed by an enhancement of antioxidant capacity and catalase antioxidant system.

    Full Text Available Depressive symptoms in adolescence have been a subject of considerable controversy in terms of their nature, severity and identification. The aim of the study was to investigate the possible association between weight status and depressive symptoms among 18 year-old Greek adolescents. A cross-sectional study design was used. The study population consisted of 200 students of the University of Athens who fulfilled the following criteria: age 18 years, absence of clinical depression, no history of hospitalization in a mental institution, no history of alcohol abuse. Weight status was assessed by Body Mass Index (BMI (kg/m2 and calculated from weight and height measurements. Severity of depressive symptoms was assessed by Centre for Epidemiologic Studies-Depression Scale (CES-D. In univariate analysis, CES-D score was significantly associated with adolescents’ gender and BMI. The multivariate analysis showed that CES-D score was negatively related to BMI even after controlling the confounding effect of gender (P=0.018, B=-0.378. Depressive symptoms are related to weight status of adolescents.

    To determine lipid profiles in early childhood and evaluate their association with weight status at 4 years of age. Additionally, we evaluated whether the risk of overweight or having an altered lipid profile was associated with parental weight status. Five hundred eighty two mothers and their 4-year-old children from 2 Spanish population-based cohorts were studied. Weight status in children at 4 years of age was classified as overweight or obese using the International Obesity Task Force criteria. Plasma total cholesterol, triglycerides, high-density lipoprotein cholesterol, and low-density lipoprotein cholesterol were determined in children and lipid ratios were calculated. A proatherogenic lipid profile was defined as having the 3 lipid ratios in the third tertile. A total of 12.9% of children were overweight and 6.4% were obese. Weight status at 4 years of age was related to maternal prepregnancy body mass index, paternal body mass index, gestational diabetes, and birth weight, but not with other sociodemographic characteristics of the mother. We found no association with gestational age, sex of the child, or breastfeeding. The risk of overweight/obesity was increased 4.17-fold if mothers were overweight/obese (95% CI 1.76-9.88) and 5.1-fold (95% CI 2.50-10.40) if both parents were overweight/obese. There were 133 children (22.8%) with a proatherogenic lipid profile. The risk of a proatherogenic lipid profile was increased 2.44-fold (95% CI 1.54-3.86) if they were overweight/obese at 4 years of age and 2-fold if the father was overweight/obese (95% CI 1.22-3.35). Four-year-old overweight/obese children have higher lipid risk profiles. Offspring of overweight/obese parents have an increased risk for obesity and a proatherogenic lipid profile.

    Full Text Available Abstract Background Childhood obesity is a substantial public health problem. The extent to which health state preferences (utilities are related to a child's weight status has not been reported. The aims of this study were (1 to use a generic health state classification system to measure health related quality of life and calculate health utilities in a convenience sample of children and adolescents and (2 to determine the extent to which these measures are associated with weight status and body mass index (BMI. Methods We enrolled 76 children 5-18 years of age from a primary care clinic and an obesity clinic in Boston MA. We administered the Health Utilities Index (HUI and used the HUI Mark 3 single- and multi-attribute utility functions to calculate health utilities. We determined BMI percentile and weight status based on CDC references. We examined single-attribute and overall utilities in relation to weight status and BMI. Results Mean (range age was 10.8 (5-18 years. Mean (SD BMI percentile was 76 (26; 55% of children were overweight or obese. The mean (SD overall utility was 0.79 (0.17 in the entire sample. For healthy-weight children, the mean overall utility was higher than for overweight or obese children (0.81 vs. 0.78, but the difference was not statistically significant (difference 0.04, 95% CI -0.04, 0.11. Conclusions Our results provide a quantitative estimate of the health utility associated with overweight and obesity in children, and will be helpful to researchers performing cost effectiveness analyses of interventions to prevent and/or treat childhood obesity.

  12. Body weight decreases induced by estradiol in female rhesus monkeys are dependent upon social status

    2010-01-01

    Gonadal steroids regulate appetite and thus body weight. In addition, continuous exposure to stressors negatively influences appetite through circuits likely distinct from those of gonadal steroids. The occurrence of adverse metabolic consequences due to chronic exposure to psychosocial stressors is twice as frequent in women as men, implicating a role for ovarian hormones, estradiol (E2) and progesterone (P4), in modulating stress-induced changes in appetite. Using social subordination in female macaques as a model of social stress, the current study tested the hypothesis that subordinate females would lose more weight during E2 treatment and gain less weight during P4 administration than dominant females. Because polymorphisms in the gene encoding the serotonin transporter (5HTT; SCL6A4) are known to alter responsivity to stress, we hypothesized that weight loss during E2 administration would be greatest in females with the short variant (s-variant) allele of 5HTT. Dominant females were significantly heavier than subordinate animals throughout the study, a result consistent with previous accounts of food intake when animals are fed a low-fat, high-fiber diet. Females with the s-variant 5HTT genotype weighed significantly less than l/l animals. Dominant animals lost significantly more weight than subordinate animals during E2 treatment. Administration of P4 blocked the weight-reducing effects of E2 in all females, regardless of social status. These data provide evidence that social subordination modulates the influence of ovarian steroid hormones on body weight in female rhesus monkeys independent of 5HTT genotype. Given the prosocial effects of these steroids, future studies are necessary to determine whether status differences in E2-induced weight loss are due to diminished food intake and or increases in energy expenditure and how the change in energy availability during E2 treatments relates to a female’s motivation to interact with conspecifics.

    Transient imaging abnormalities, including changes on diffusion-weighted imaging (DWI), may be seen in focal status epilepticus. The changes on DWI provide an insight into the pathophysiology. We report a 53-year-old man with focal motor status epilepticus involving the left hand, arm and face with focal slowing on EEG. The apparent diffusion coefficients (ADC) were higher in the affected hemisphere than on the other side. At 10 days and 6 weeks after the end of the seizures, we saw normal ADCs and atrophy of the affected hemisphere. We conclude that the MRI findings indicate both cytotoxic and vasogenic oedema during seizure activity and subsequent loss of brain parenchyma. (orig.)

    Birth weight is considered as the most important indicator of growth and intrauterine development as well as the nutritional status of the newborn. Several reports have demonstrated the influence of both biological and social variables on low birth weight, among which being discussed is the influence of the mothers work activities. Two hundred and thirty-two newborns were studied at the Regional Hospital "20 de Noviembre" of the Institute de Seguridad y Servicios Sociales para los Trabajadores del Estado (ISSSTE) and selected based on inclusion and exclusion criteria which homogenized the sample and allowed to associate the work status of the mother with the low birth weight of the child. The somatometric data of the newborns was obtained from official registrars from the Perinatology Ward and directly from the mothers who were interviewed. The results did not significant statistical differences in the weight of the newborns of those mothers who do work than in those who don't. It was concluded that for this sample, the favorable socioeconomic fund established by a double family income apparently compensates any disadvantages which the work activity could have on the newborns' weight.

    Full Text Available Introduction & Objective: Recent studies have presented evidence that periodontal disease in pregnant women may be a determining factor for newborn’s low birth weight. The present investigation was carried out to verify whether there is an association between maternal periodontal disease and low birth weight of newborns.Materials and Methods: This was a case-control study on 330 women, containing 110 mothers having live newborns with weight 2500 g (control group. The existence of an association between periodontal disease and newborn’s low birth weight was evaluated by means of analytic statistics that considered other risk factors for low weight. The two groups were compared with regard to urinary infection, preeclampsia, premature rupture of membrane, placenta previa, primiparous, smoking, age, height, socioeconomic status and periodontal disease.Results: There were no statistically significant differences between the case and control groups for any of the covariables (P>0.05, but there was significant differences for principal independent variable (periodontal disease P<0.05.Conclusion: Results indicated a positive association between periodontal disease and newborn’s low birth weight. Thus periodontal disease is a possible risk factor for low birth weight.

    We sought to determine whether change in weight status between adolescence and young adulthood was associated with the risk of developing hypertension among adolescents and whether sex and racial/ethnic group differences existed in the National Longitudinal Study of Adolescent Health. The sample was restricted to participants who self-identified as black, Hispanic, or white non-Hispanic (n=8543). Height and weight were measured in adolescence (mean 16 years) and again in adulthood (mean 29 years). We categorized the weight of participants into 4 groups: stayed normal weight; gained weight (normal weight in adolescence and obese in adulthood); lost weight (overweight/obese in adolescence nonobese in adulthood); and chronically overweight/obese. Hypertension was defined as measured systolic blood pressure of at least 140 mm Hg or diastolic blood pressure of at least 90 mm Hg measured in adulthood or use of antihypertensive medications. A higher risk of hypertension was noted for all sex and racial/ethnic groups who became obese in adulthood. Furthermore, those who were chronically overweight/obese were at higher risk of hypertension for all groups, with odds ratios ranging from 2.7 in Hispanic men to 6.5 in Hispanic women. Except for black men, those who lost weight during follow-up had no significant increased risk compared with those who maintained normal weight. Overall, there was an increased risk of hypertension for those who gained weight in adulthood and among those who remained obese from adolescence to young adulthood. These data give further evidence for prevention strategies that begin earlier in life to reduce or delay the onset of chronic disease in young adults.

    Good nutrition, a balanced diet and regular physical activity are foundations of good health. Research has found that dietary patterns change dramatically following the arrival of students in a foreign country. However, nutritional status of Iranian students studying oversea has never been investigated. The objective of this study was to determine factors associated with body weight status of Iranian postgraduate students in Universiti of Putra Malaysia (UPM). A cross-sectional study was conducted to determine the body weight status of 210 Iranian postgraduate students aged between 22 and 55 years in University of Putra Malaysia. The associations between body weight status and socio demographics factors and also lifestyle factors (smoking and physical activity) were assessed. Anthropometric factors (height, weight, BMI and waist and hip circumferences) were measured. Chi-square, Spearman Rho and Pearson tests were used for data analysis. From a total of 210 postgraduate students 110 were females, and 100 males. No significant correlation was observed between smoking and BMI (P = 0.4). However, statistically significant correlations were observed between gender (P = 0.007), physical activity (P = 0.02), using protein (P = 0.005), carbohydrate (P = 0.002), fat (P = 0.001), fiber (P = 0.003), vitamin C (P = 0.04), calcium (P = 0.005), waist circumference (P = 0.02), hip circumference (P = 0.001), Waist to Hip Ratio (P = 0.002), and BMI. The nutritional behavior of university students was poor. Therefore, it is essential to encourage young people, including university students to enrich their diets with milk, beans, fruit, and vegetables to decrease the risks of nutrition related disorders.

    Several expected correlations among followed internal plant traits were confirmed using the dataset of 492 herbaceous species from the temporal zone of Central Europe. Average diaspore weight (seed mass), reproductive capacity of population (number of produced diaspores), species height, and ability of lateral spread were the plant traits considered. The evident correlations were confirmed among all investigated traits: (i) The reproductive capacity of population negatively correlated with diaspore weight, plant height, and vegetative propagation. The diaspore weight and their number are closely correlated and co-adapted. (ii) Bigger plant species produce bigger diaspores. These trends are obvious at the inter- and intra-family levels. (iii) Larger plant species showed higher ability to vegetative propagation.

    Full Text Available Childhood obesity and asthma are on the rise in the U.S. Clinical and epidemiological data suggest a link between the two, in which overweight and obese children are at higher risk for asthma. Prevention of childhood obesity is preferred over treatment, however, in order to be receptive to messages, parents must perceive that their child is overweight. Many parents do not accurately assess their child’s weight status. Herein, the relation between parental perceptions of child weight status, observed body mass index (BMI percentiles, and a measure of child feeding practices were explored in the context of asthma, food allergy, or both. Out of the children with asthma or food allergy that were classified as overweight/obese by BMI percentiles, 93% were not perceived as overweight/obese by the parent. Mean scores for concern about child weight were higher in children with both asthma and food allergy than either condition alone, yet there were no significant differences among the groups in terms of pressure to eat and restrictive feeding practices. In summary, parents of children with asthma or food allergy were less likely to recognize their child’s overweight/obese status and their feeding practices did not differ from those without asthma and food allergy.

    To examine, using an Ecological Systems Theoretical framework, relationships between weight status and child, parent and community characteristics and risk factors among preschool children. Cross-sectional data was collected from 140 children and their parents from 11 randomly selected preschools. Outcome variables included: motor development; perceived competence; objectively measured physical activity; time spent in active and quiet play; location and number of televisions; parental rules around physical activity and time spent watching television; availability of sport and physical activity programs; and parks and open spaces and access to footpaths. Overweight children spent more time in quiet play and watching television and less time in active play and physical activity. Perceived competence and motor development were similar for both overweight and non-overweight children. Associations between weight status and several parent and community characteristics were not evident, except for access to footpaths. Overweight children had greater access to footpaths compared with non-overweight children (p=0.046). The results reported here showed little difference between overweight and non-overweight children in relation to a variety of child, parent and community variables. However, for some characteristics, differences in older children have been reported. Longitudinal studies are required to confirm when these characteristics begin to differ, what effects these differences have on behaviour and weight-status, and therefore when targeted treatment should be provided during a child's development.

    Diet quality may be influenced by social determinants and weight status. This has not been studied in Puerto Rico; therefore, our cross-sectional study examined whether diet quality, assessed by the Healthy Eating Index-2005 (HEI-2005), differs by social determinants (sex, school type, and region) and weight status in children in Puerto Rico. As part of an island-wide study to evaluate oral health in 1,550 children aged 12 years, dietary intake was assessed in a representative subset (n=796) using a 24-hour diet recall. Diet quality was evaluated from the diet recall results using the HEI-2005. Overall mean HEI-2005 score was 40.9, out of a total maximum score of 100. Girls had significantly higher scores for whole fruit, total vegetables, whole grains, and sodium but lower scores for total grains and milk compared with boys (Pdiet quality were associated with the social determinants studied and with weight status in our sample. Overall diet quality needs improvement in Puerto Rican children so that it is better aligned with dietary recommendations.

    Full Text Available Objective. To explore the associations between sitting time in various domains and mental health for workers and nonworkers and the role of weight status. Design. Cross-sectional analyses were performed for 1064 respondents (47% men, mean age 59 years from the Doetinchem Cohort Study 2008-2009. Sedentary behavior was measured by self-reported time spent sitting during transport, leisure time, and at work. Mental health was assessed by the Mental Health Inventory (MHI-5. BMI was calculated based on measured body height and weight. Results. Neither sitting time during transport nor at work was associated with mental health. In the working population, sitting during leisure time, and particularly TV viewing, was associated with poorer mental health. BMI was an effect modifier in this association with significant positive associations for healthy-weight non-workers and obese workers. Conclusion. Both BMI and working status were effect modifiers in the relation between TV viewing and mental health. More longitudinal research is needed to confirm the results and to gain insight into the causality and the underlying mechanisms for the complex relationships among sedentary behaviors, BMI, working status, and mental health.

    Full Text Available Introduction: Eating style is one of the prominent factors that determine energy intake. One of the influencing factors that determine parental feeding style is parental perception of the weight status of the child. Aim: The aim of this study is to evaluate the relationship between maternal visual perception of their children's weight status and their feeding style. Method: A cross-sectional survey was completed with only mother's of 380 preschool children with age of 5 to 7 (6.14 years. Visual perception scores were measured with a sketch and maternal feeding style was measured with validated "Parental Feeding Style Questionnaire". Results: The parental feeding dimensions "emotional feeding" and "encouragement to eat" subscale scores were low in overweight children according to visual perception classification. "Emotional feeding" and "permissive control" subscale scores were statistically different in children classified as correctly perceived and incorrectly low perceived group due to maternal misperception. Conclusion: Various feeding styles were related to maternal visual perception. The best approach to preventing obesity and underweight may be to focus on achieving correct parental perception of the weight status of their children, thus improving parental skills and leading them to implement proper feeding styles.

    To examine neighbourhood food environments, adolescent nutrition and weight status. Cross-sectional, observational study. Minneapolis/St. Paul metropolitan region, Minnesota, USA. A total of 349 adolescents were recruited to the study. Participants completed 24 h dietary recalls and had their weight and height measured. They also reported demographic information and other diet-related behaviours. Geographic Information Systems were used to examine the availability and proximity of food outlets, particularly those captured within the 800, 1600 and/or 3000 m network buffers around participants' homes and schools. Adjusting for gender, age and socio-economic status, adolescents' sugar-sweetened beverage intake was associated with residential proximity to restaurants (including fast food), convenience stores, grocery stores and other retail facilities within the 800 and/or 1600 m residential buffers (P ≤ 0·01). BMI Z-score and percentage body fat were positively associated with the presence of a convenience store within a 1600 m buffer. Other individual-level factors, such as energy, fruit and vegetable intake, as well as convenience store and fast food purchasing, were not significantly associated with features of the residential neighbourhood food environment in adjusted models. In addition, school neighbourhood environments yielded few associations with adolescent outcomes. Many factors are likely to have an important role in influencing adolescent dietary intake and weight status. Interventions aimed at increasing neighbourhood access to healthy foods, as well as other approaches, are needed.

    The purpose of this study was to describe the relationship among variables which are associated with life-style modification, knowledge of diabetes, social support, health practices, and body mass index, to examine their effect on health status, and to test the effectiveness of a community based life-style modification program for weight control. Adults (n = 66) with non-insulin-dependent diabetes mellitus participated in either a treatment or control group. The treatment consisted of 5 weekly 90-min sessions on modifying eating and exercise patterns. All participants completed a personal resource questionnaire (PRQ), health practices survey (HPS), and diabetes health status questionnaire (DHS) at intake, 5 weeks, and 4 months. Knowledge of diabetes was assessed only at intake. Knowledge of diabetes, social support, and health practices explained 27% of the variance in health status, but health practices explained the largest (18%) proportion of the variance and was the only study variable significantly affected by the life-style modification program.

    The effect of diet quality on weight change, relative to other body weight determinants, is insufficiently understood. Furthermore, research on long-term weight change in U.S. adults is limited. We evaluated prospectively patterns and predictors of weight change in Framingham Offspring/Spouse (FOS) women and men (n = 1515) aged ≥30 y with BMI ≥ 18.5 kg/m2 and without cardiovascular disease, diabetes, and cancer at baseline over a 16-y period. Diet quality was assessed using the validated Framingham Nutritional Risk Score. In women, older age (P < 0.0001) and physical activity (P < 0.05) were associated with lower weight gain. Diet quality interacted with former smoking status (P-interaction = 0.02); former smokers with lower diet quality gained an additional 5.2 kg compared with those with higher diet quality (multivariable-adjusted P-trend = 0.06). Among men, older age (P < 0.0001) and current smoking (P < 0.01) were associated with lower weight gain, and weight fluctuation (P < 0.01) and former smoking status (P < 0.0001) were associated with greater weight gain. Age was the strongest predictor of weight change in both women (partial R2 = 11%) and men (partial R2 = 8.6%). Normal- and overweight women gained more than obese women (P < 0.05) and younger adults gained more weight than older adults (P < 0.0001). Patterns and predictors of weight change differ by sex. Age in both sexes and physical activity among women as well as weight fluctuation and smoking status in men were stronger predictors of weight change than diet quality among FOS adults. Women who stopped smoking over follow-up and had poor diet quality gained the most weight. Preventive interventions need to be sex-specific and consider lifestyle factors. PMID:20484553

Height, weight, waist circumference, blood pressure and random glucose levels were measured. Twenty percent of the sample had normal weight (body mass index (BMI, kg/m2 25 to 140/90 mmHg: 50.3%, and were inactive (48.7% with a high waist circumference (> 82 cm: 57.4%. Educators' nutrition and physical activity knowledge was poor. Sixty-nine percent of educators incorrectly believed that eating starchy foods causes weight gain and only 15% knew that one should eat five or more fruit and/or vegetables per day. Aspects of poor nutritional knowledge, misconceptions regarding actual body weight status, and challenges in changing health behaviours, emerged as issues which need to be addressed among educators. Educators' high risk for developing chronic non-communicable diseases (NCDs may impact on educator absenteeism and subsequently on school functioning. The aspects of poor nutrition and physical activity knowledge along with educators' high risk for NCD development may be particularly significant not merely in relation to their personal health but also the learners they teach.

Objective: To assess the effect of maternal nutritional status during pregnancy on the birth weight of the baby among tea tribe women in Dibrugarh district. Study Design: Field-based cohort study. Setting: Five tea estates in Dibrugarh District, Assam. Period of Study: One year (April 1998 to April 1999. Participants: A cohort of non-pregnant currently married tea garden women of reproductive age group (15-44 years from similar socio-economic background. Materials and Methods: Oral questionnaire for age, family structure, obstetric history, annual income, and period of gestation. Anthropometric measurements of weight and height were recorded using bathroom scales and the anthropometric rod. Measurements of weight were repeated during the first, second, and third trimesters of pregnancy. Birth weight of the baby was recorded at delivery, irrespective of the period of gestation and mode of delivery. Statistical Analysis: Correlation co-efficient, standard deviation, and regression analysis. Results and Conclusions: Of all, 88% mothers had pre-pregnant weight of < 45 kg, and 61% babies had birth weight < 2500 gm. Subjects with better pre-pregnant weight had corresponding favorable total weight gain, resulting in better birth weight of the babies. Pre-pregnant weight had direct positive linear relationship with the birth weight. There is a need to improve the nutritional status of the adolescent girl in order to build up her pre-pregnant weight for a favorable birth weight.

    Parental obesity is highly predictive of child obesity, and preterm infants are at greater risk of obesity, but little is known about obese and non-obese mothers' responsiveness to preterm infant cues during feeding. The relationship between maternal weight status and response to preterm infant behavioral cues during feeding at 6-weeks corrected age was examined. This secondary analysis used data from a randomized clinical trial. Maternal weight was coded during a play session. Mother-infant interaction during feeding was coded using the Nursing Child Assessment Satellite Training Feeding Scale (NCAST). We used multivariate linear regressions to examine NCAST scores and multivariate logistic regressions for the two individual items, satiation cues and termination of feeding. Of the 139 mothers, 56 (40.3%) were obese, two underweight women were excluded. Obese mothers did not differ from overweight/normal weight mothers for overall NCAST scores, but they had higher scores on response to infant's distress subscale (mean = 10.2 vs. 9.6, p = 0.01). The proportion of infants who exhibited satiation cues did not differ by maternal weight. Obese mothers were more likely than overweight/normal weight mothers to terminate the feeding when the infant showed satiation cues (82.1% vs. 66.3%, p = 0.04, adjusted OR = 2.31, 95% CI = 0.97, 5.48). Limitations include lack of BMI measures and small sample size. Additional research is needed about maternal weight status and whether it influences responsiveness to preterm infant satiation cues. Results highlight the need for educating all mothers of preterm infants regarding preterm infant cues. NCT02041923 . Feeding and Transition to Home for Preterms at Social Risk (H-HOPE).

    Two fields are reserved for the application of rocket power plants. The first field is determined by the fact that the rocket power plant is the only type of power plant that can produce thrust without dependence upon environment. For this field,the rocket is therefore the only possible power plant and the limit of what may be done is determined by the status of the technical development of these power plants at the given moment. The second field is that in which the rocket power plant proves itself the most suitable as a high-power drive in free competition with other types of power plants. The exposition will be devoted to the demarcation of this field and its division among the various types of rocket power plants.

    Although the positive association between pre-pregnancy overweight and obesity with excessive gestational weight gain is well known, it is not clear how pre-pregnancy weight status is associated with gestational weight gain through maternal diet during pregnancy. This study aimed to examine the relationship between pre-pregnancy weight status and diet quality and maternal nutritional biomarkers during pregnancy. Our study included 795 U.S. pregnant women from the National Health and Nutrition Examination Survey, 2003-2012. Pre-pregnancy body mass index (BMI) was calculated based on self-reported pre-pregnancy weight and height. The cutoff points of pregnancy was assessed by the Healthy Eating Index (HEI)-2010 based on a 24-h recall. Multivariable logistic regressions were used to estimate the odds ratios (OR) and 95% confidence intervals (CI). For all pregnant women included in this study, the mean HEI-2010 (±standard error of the mean (SEM)) was 50.7 (±0.9). Women with obese pre-pregnancy BMI demonstrated significantly lower HEI-2010 compared to those with underweight and normal pre-pregnancy BMI, respectively. In an unadjusted model, women with pre-pregnancy obesity BMI had increased odds for being in the lowest tertile of HEI-2010 (33.4 ± 0.5) compared to those with underweight pre-pregnancy BMI (OR 5.0; 95% CI 2.2-11.4). The inverse association between pre-pregnancy overweight and obesity status and diet quality during pregnancy persisted even after we controlled for physical activity levels (adjusted OR (AOR) 3.8; 95% CI 1.2-11.7, AOR 5.4; 95% CI 2.0-14.5, respectively). Serum folate concentration (ng/mL) was significantly higher in underweight women compared to overweight women (23.4 ± 1.7 vs. 17.0 ± 0.8, p pregnancy weight status and diet quality and maternal nutritional biomarkers during pregnancy.

    Full Text Available Abstract Background Health professionals have an important role to play in the management of obesity, but may be unsure how to raise weight issues with patients. The societal stigma associated with excess weight means that weight status terms may be misunderstood, cause offence and risk upsetting patient-professional relationships. This study investigated the views of people who were overweight or obese on the acceptability of weight status terms and their potential to motivate weight loss when used by health professionals. Methods A qualitative study comprising 34 semi-structured interviews with men and women in their mid-to-late 30s and 50s who were overweight or obese and had recently been informed of their weight status. Thematic framework analysis was conducted to allow the systematic comparison of views by age, gender and apparent motivation to lose weight. Results Although many people favoured 'Overweight' to describe their weight status, there were doubts about its effectiveness to motivate weight loss. Terms including 'BMI' ('Body Mass Index' or referring to the unhealthy nature of their weight were generally considered acceptable and motivational, although a number of men questioned the validity of BMI as an indicator of excess weight. Participants, particularly women, felt that health professionals should avoid using 'Fat'. Whilst response to 'Obese' was largely negative, people recognised that it could be appropriate in a health consultation. Some younger people, particularly those who appeared motivated to lose weight, felt 'Obese' could encourage weight loss, but it was also clear the term could provoke negative emotions if used insensitively. Conclusions Although most people who are overweight or obese accept that it is appropriate for health professionals to discuss weight issues with patients, there is great variation in response to the terms commonly used to describe excess weight. There is no one-size-fits-all approach to

    Weight gain and concerns about weight can influence a smoker's ability to successfully quit, and young adults are a subgroup of smokers who are particularly concerned about the impact of quitting on their body weight. This study explored the associations between body mass index (BMI), weight perceptions, and smoking status among young adults. The sample consisted of 4,027 young adults between the ages of 18 and 29 who participated in a randomized control trial of the National Cancer Institute's SmokefreeTXT program. Multivariable logistic regression models were used to examine the association between weight related variables and smoking status. Obese participants had a 0.72 lower odds (95% CI: 0.62, 0.85) of reporting smoking at the end of the program than participants of normal weight, and this difference persisted over time. Weight perceptions were also associated with smoking status. Those who perceived themselves to be slightly underweight/underweight were more likely to report smoking than those who reported being just about the right weight (OR: 1.53, 95% CI: 1.20, 1.95), and those who strongly disagreed that smoking cigarettes helps people keep their weight down were less likely to report smoking at the end of treatment than those who neither agreed nor disagreed with this statement (OR: 0.69, 95% CI: 0.54, 0.87). Weight related factors assessed at baseline predicted smoking status at the end of treatment and through long term follow up. Smoking cessation programs that tailor content to addresses the specific needs of weight concerned smokers may enhance effectiveness. This study explores the association between weight related factors and smoking status among young adults, a priority population for smoking cessation efforts. This study demonstrates that both actual weight and weight perceptions (e.g., perception of body weight, perception of associations between smoking and weight) are associated with smoking outcomes, and thus need to be a considered in the

    Family rules may be influential in helping children to modify their dietary and sedentary behaviors, which are important modifiable risk factors for childhood obesity. However, data examining family rules in relation to children's health behaviors and weight status are limited. This cross-sectional study examined differences in family rules by demographic characteristics of students enrolled in the HEROES (Healthy, Energetic, Ready, Outstanding, Enthusiastic Schools) Initiative, a school-based childhood obesity prevention program. It also investigated the relationship between eating and screen time family rules and six eating and screen time behaviors: fast food consumption; soft drink consumption; fruit and vegetable intake; television viewing; computer use; and video game use, in addition to the association between family rules and children's weight status. Measures included self-reported behavioral data and anthropometric data from students in fourth to eighth grade at 16 schools (N=2819) in a tri-state area of the United States in spring 2012. Approximately one-third of students had each of the family rules examined. Whereas the profile of students who had specific rules varied, in general, younger, female, white, and low socioeconomic status students were more likely to have rules than their counterparts. Family rules were associated with healthier outcomes for each of the six behaviors examined (p<0.001), even after controlling for demographics (p<0.001). However, family rules were not associated with children's weight status. This study demonstrates that family rules are an underutilized strategy to promote healthier eating habits and reduce children's screen time hours and may serve as an intermediary mechanism to curb childhood obesity.

    Growing body of literature has reported that weight status estimation pattern, including accurate-, under-, and overestimation, was associated with weight related behaviors and weight change among adolescents and young adults. However, there have been a few studies investigating the potential role of school contexts in shaping adolescents' weight status estimation pattern among Korea adolescents. The aim of the present study was to investigate the association between weight status misperception patterns and factors at individual-, family-, and school-level, simultaneously, and whether there was significant between schools variation in the distribution of each weight status misperception pattern, underestimation and overestimation respectively, among Korean adolescents aged 12-18 years. Data from the Eighth Korea Youth Risk Behavior Web-based Survey (KYRBS), 2012, a nationally representative online survey of 72,228 students (boys = 37,229, girls = 34,999) from a total of 797 middle and high schools were used. Sex stratified multilevel random intercept multinomial logistic models where adolescents (level 1) were nested within schools (level 2) were performed. At the school level, attending a school with higher average BMI (kg/m2) was positively associated with weight status underestimation, and inversely associated with weight status overestimation among boys and girls. Single-sex schooling was positively associated with weight status underestimation among girls. At the family level, higher household income (high/middle versus low) was inversely associated with both weight status under- and overestimation among boys and girls. Higher maternal education (equal to or more than college graduate versus equal to or less than high school graduate) was positively associated with weight status overestimation among boys, and living with both parents (compared to not living with both parents) was inversely associated with weight status underestimation among girls.

    Full Text Available Abstract Background In a longitudinal population-based study of the relationship between body mass index (BMI in early adulthood and marital status at 40 years of age, obese men were half as likely to be married compared with men of normal weight. Significant associations between obesity and marital status among men in a longitudinal setting are novel findings. Methods The study cohort comprised Swedish men born from 1951 to 1961. Height and weight at age 18 was gathered from the Military Service Conscription Register and information on marital status at 40 years of age was obtained from population registers by record-linkage using the unique personal identification number. The odds ratio (OR for being married was calculated by polytomous logistic regression analysis adjusting for birth year, intellectual performance, education, country of birth, residential area, socioeconomic position in childhood and adulthood, parental education and muscle strength. Results Our study included 486 599 Swedish men. Young men who were obese (BMI≥30.0 at 18 years of age had an OR of 0.49 (95% CI: 0.46–0.52 for being married at 40 years of age compared to normal weight men (BMI: 18.5–24.9. Underweight men (BMI≤18.5 had an OR of 0.84 (0.82–0.86 and overweight men (BMI: 25.0–29.9 had an OR of 0.83 (0.80–0.85 for being married at 40 years of age. Conclusion Underweight, overweight and obese men were less likely to be married than their normal weight counterparts. Obese men had the lowest likelihood of being married. Stigmatization and discrimination may partly explain these findings, but further research is needed before firm conclusions can be drawn.

    Full Text Available Background. Prior studies suggest that weight satisfaction may preclude changes in behavior that lead to healthier weight among individuals who are overweight or obese. Objective. To gain a better understanding of complex relationships between weight satisfaction, weight-related health behaviors, and health outcomes. Design. Cross-sectional analysis of data from the Aerobics Center Longitudinal Study (ACLS. Participants. Large mixed-gender cohort of primarily white, middle-to-upper socioeconomic status (SES adults with baseline examination between 1987 and 2002 (n=19,003. Main Outcome Variables. Weight satisfaction, weight-related health behaviors, chronic health conditions, and clinical health indicators. Statistical Analyses Performed. Chi-square test, t-tests, and linear and multivariate logistic regression. Results. Compared to men, women were more likely to be dieting (32% women; 18% men and had higher weight dissatisfaction. Men and women with greater weight dissatisfaction reported more dieting, yo-yo dieting, and snacking and consuming fewer meals, being less active, and having to eat either more or less than desired to maintain weight regardless of weight status. Those who were overweight or obese and dissatisfied with their weight had the poorest health. Conclusion. Greater satisfaction with one’s weight was associated with positive health behaviors and health outcomes in both men and women and across weight status groups.

    To determine the amount of time children play outdoors and examine associations with weekday, weekend and after-school physical activity (PA), sedentary behavior (SB), and weight-status (normal-weight, overweight/obese). Data were extracted from Project BEAT (Toronto, 2010-2011; www.beat.utoronto.ca). Children's (n=856; mean age=11±0.6years) PA and SB were measured using accelerometry. Outdoor play (OP) was assessed via parental report and collapsed into three categories (2h/day) and differences in anthropometric and PA characteristics were assessed. 55.1%, 37.2%, and 7.7% of children played outdoors for 2h/day, respectively, on weekdays. OP was higher on weekends and in boys. OP was associated with SB, light PA and MVPA at all time-points, whereby children attaining activity profiles. Boys playing outdoors for overweight/obese and had lower PA levels than normal weight boys. However, overweight/obese boys who spent >2h/day playing outdoors had PA profiles similar to normal weight counterparts. Encouraging children to spend more time outdoors may be an effective strategy for increasing PA, reducing SB, and preventing excess weight gain (particularly boys' play).

    Serum concentrations of osteocalcin (OC) decrease and those of C-terminal telopeptide of type 1 collagen (CTX) increase during weight loss in adolescent girls with eating disorders (ED). The impact of weight loss on bone metabolism markers is greatest in premenarcheal girls. Adolescents with ED stand a risk of not reaching optimal peak bone mass and develop osteoporosis. Previous investigations are contradictory as to how markers of bone formation and resorption change during weight loss and nutritional rehabilitation. Serum OC and CTX were measured at assessment of 461 adolescent girls with ED and during treatment of 55 girls with anorexia nervosa. Bone metabolism was related to weight, weight change and growth rate. At assessment, OC concentrations were positively correlated with growth rate and inversely with age and (rate of) weight loss. Growth rate was the only predictor of CTX concentrations in premenarcheal girls. In postmenarcheal girls, CTX concentrations were inversely correlated with age and rate of weight loss. During weight gain, there was an increase of OC concentrations. CTX concentrations decreased at the onset of weight gain and increased when near normal weight was reached. Bone formation markers decrease and resorption markers increase during weight loss. The effects are independent of menstrual status but the impact on bone formation markers is greater in young, premenarcheal girls. Markers are normalised during weight gain but it is conceivable that repeated and/or prolonged weight loss in adolescents reduces peak bone mass.

    To examine cross-sectional and longitudinal associations between behavioral problems and weight status, considering body mass index (BMI) z-scores and overweight status, in a community sample of preschoolers. The Strengths and Difficulties Questionnaire and the Diagnostic Interview for Children and Adolescents were administered to 611 parents. Adjusted general linear models and binary logistic regressions were used. Children who were overweight and had a higher BMI were at increased risk of peer problems and attention-deficit/hyperactivity disorder (ADHD) symptoms. Prospective analyses showed that a higher BMI at the age of 3 years was predictive of peer problems at ages 4 and 5 years and hyperactivity and ADHD symptoms at the age of 4 years. This is the first study using a diagnostic-based instrument that shows a relationship between weight status and ADHD symptoms in preschoolers. Overweight children might benefit from screening for behavioral disorders and peer relationship problems. © The Author 2014.

    Full Text Available Although the positive association between pre-pregnancy overweight and obesity with excessive gestational weight gain is well known, it is not clear how pre-pregnancy weight status is associated with gestational weight gain through maternal diet during pregnancy. This study aimed to examine the relationship between pre-pregnancy weight status and diet quality and maternal nutritional biomarkers during pregnancy. Our study included 795 U.S. pregnant women from the National Health and Nutrition Examination Survey, 2003–2012. Pre-pregnancy body mass index (BMI was calculated based on self-reported pre-pregnancy weight and height. The cutoff points of <18.5 (underweight, 18.5–24.9 (normal, 25.0–29.9 (overweight, and 30 kg/m2 (obese were used to categorize pregnant women’s weight status. Diet quality during pregnancy was assessed by the Healthy Eating Index (HEI-2010 based on a 24-h recall. Multivariable logistic regressions were used to estimate the odds ratios (OR and 95% confidence intervals (CI. For all pregnant women included in this study, the mean HEI-2010 (±standard error of the mean (SEM was 50.7 (±0.9. Women with obese pre-pregnancy BMI demonstrated significantly lower HEI-2010 compared to those with underweight and normal pre-pregnancy BMI, respectively. In an unadjusted model, women with pre-pregnancy obesity BMI had increased odds for being in the lowest tertile of HEI-2010 (33.4 ± 0.5 compared to those with underweight pre-pregnancy BMI (OR 5.0; 95% CI 2.2–11.4. The inverse association between pre-pregnancy overweight and obesity status and diet quality during pregnancy persisted even after we controlled for physical activity levels (adjusted OR (AOR 3.8; 95% CI 1.2–11.7, AOR 5.4; 95% CI 2.0–14.5, respectively.

    AIM: We investigated the relationship between taste sensitivity, nutritional status and metabolic syndrome and possible implications on weight loss dietary program. METHODS: Sensitivity for bitter, sweet, salty and sour tastes was assessed by the three-Alternative-Forced-Choice method in 41 overweight(OW), 52 obese(OB) patients and 56 normal-weight matched controls. OW and OB were assessed also for body composition(by impedence), resting energy expenditure(by indirect calorimetry) and presence of metabolic syndrome(MetS) and were prescribed a weight loss diet. Compliance to the weight loss dietary program was defined as adherence to control visits and weight loss ≥ 5% in 3 mo. RESULTS: Sex and age-adjusted multiple regression models revealed a significant association between body mass index(BMI) and both sour taste(P < 0.05) and global taste acuity score(GTAS)(P < 0.05), with lower sensitivity with increasing BMI. This trend in sensitivity for sour taste was also confirmed by the model refitted on the OW/OB group while the association with GTAS was marginally significant(P = 0.06). MetS+ subjects presented higher thresholds for salty taste when compared to MetS- patients while no significant difference was detected for the other tastes and GTAS. As assessed by multiple regression model, the association between salty taste and MetS appeared to be independent of sex, age and BMI. Patients continuing the program(n = 37) did not show any difference in baseline taste sensitivity when compared to drop-outs(n = 29). Similarly, no significant difference was detected between patients reporting and not reporting a weight loss ≥ 5% of the initial body weight. No significant dif-ference in taste sensitivity was detected even after dividing patients on the basis of nutritional(OW and OB) or metabolic status(MetS+ and MetS-). CONCLUSION: There is no cause-effect relationship between overweight and metabolic derangements. Taste thresholds assessment is not useful in

    The purpose of this study was to examine the conceptual gap between self-perceived weight and body mass index (BMI), and to assess the knowledge gap between perceived importance of following dietary guidelines and health literacy levels. Adults (n = 131) eligible for the Supplemental Nutrition Assistance Program (SNAP) were interviewed at eleven SNAP regional offices in Maryland. Based on BMI calculated from self-reported height and weight, 65.6% of participants were overweight or obese while 40.5% perceived that they were overweight or obese. In sub-group analysis categorized by BMI, only 20.0% in the overweight and 20.0% in the obese group correctly perceived themselves as being overweight or obese. Following dietary guidelines was perceived as important by a majority of participants, but only 43.5% had adequate health literacy. Conceptual and knowledge gaps between self-perception and objective health status existed in the low-income SNAP-eligible sample. Future studies need to address these gaps because misperceived weight status and insufficient health literacy are critical barriers to inducing behavioral change.

    Several environmental factors contribute to increased food consumption and play a role in the prevalence of obesity, like portion size, accessibility and relative price of high caloric foods, food commercials, and sales promotions. However, not everyone seems equally sensitive to these environmental cues and both obesity and impulsivity appears to play a role. In this study, food purchases in an internet supermarket are tested in 118 participants, with or without sales promotions for snack foods. Both weight status and response inhibition, an index of impulsivity, are measured. Participants with less inhibitory control purchased in total more calories from the internet supermarket then participants with more inhibitory control. In addition, sales promotion, weight status, and inhibitory control appeared to interact in their effect on snack food purchases: participants with less inhibitory control and overweight bought more calories of snacks in the sales promotions condition, but not in the control condition. For the other participants, with normal weight and/or high inhibitory control, sales promotions had no effect on their purchases of calories of snacks. It seems that especially the combination of low inhibitory control and overweight makes participants vulnerable for environmental cues. Copyright © 2013 The Obesity Society.

    A recent study has suggested that overweight and obese people are more likely to consult a range of physicians (doctor shopping). The consistency of this finding with multiple measures of doctor shopping and controls for socioeconomic circumstances was interrogated. Ninety-nine thousand four hundred seven Australians aged 45 and over who had sought primary healthcare at least five times within 6 months of a survey (2006-2008). (i) The count of different physicians consulted; a binary indicator of (ii) >= three different physicians; (iii) >= five different physicians; and iv) a measure that took into account multiple consultations with the same physician were investigated. Weight status was measured using Body Mass Index (BMI) based on self-reported height and weight. Controls included socioeconomic circumstances, demographics, health, and neighborhood factors. In comparison to people with "normal" BMI, the likelihood of doctor shopping was lower among overweight (Incidence Rate Ratio: 0.97, 95%CI: 0.96, 0.98) and obese people (0.95: 0.93, 0.96). This negative correlation between doctor shopping behavior and weight status was consistent after full adjustment and across different outcome measures. In contrast with recent evidence from the US, overweight and obese Australians are less prone to doctor shopping behavior than their peers with "normal" BMI. Copyright © 2013 The Obesity Society.

    Full Text Available Small scale distribution of insect root herbivores may promote plant species diversity by creating patches of different herbivore pressure. However, determinants of small scale distribution of insect root herbivores, and impact of land use intensity on their small scale distribution are largely unknown. We sampled insect root herbivores and measured vegetation parameters and soil water content along transects in grasslands of different management intensity in three regions in Germany. We calculated community-weighted mean plant traits to test whether the functional plant community composition determines the small scale distribution of insect root herbivores. To analyze spatial patterns in plant species and trait composition and insect root herbivore abundance we computed Mantel correlograms. Insect root herbivores mainly comprised click beetle (Coleoptera, Elateridae larvae (43% in the investigated grasslands. Total insect root herbivore numbers were positively related to community-weighted mean traits indicating high plant growth rates and biomass (specific leaf area, reproductive- and vegetative plant height, and negatively related to plant traits indicating poor tissue quality (leaf C/N ratio. Generalist Elaterid larvae, when analyzed independently, were also positively related to high plant growth rates and furthermore to root dry mass, but were not related to tissue quality. Insect root herbivore numbers were not related to plant cover, plant species richness and soil water content. Plant species composition and to a lesser extent plant trait composition displayed spatial autocorrelation, which was not influenced by land use intensity. Insect root herbivore abundance was not spatially autocorrelated. We conclude that in semi-natural grasslands with a high share of generalist insect root herbivores, insect root herbivores affiliate with large, fast growing plants, presumably because of availability of high quantities of food.

    2012-04-01

    Full Text Available Public concern about childhood obesity and associated health problems calls for the identification of modifiable factors that could halt this epidemic. Parental perceptions of their children’s weight status could be associated to how parents influence children’s eating patterns. We aimed to identify the perceptions Puerto Rican parents have of their children’s weight and children’s own perceptions of weight status as compared to real weight. A cross sectional survey was performed in a representative sample of 1st–6th grade students. Only half of the children correctly identified their weight, and only 62.4% of the parents correctly classified their children’s weight. Most obese/overweight children did not perceive themselves as such. Almost half of obese/overweight children were identified by the parents as normal weight while over half of the underweight children were perceived by their parents at normal weight. More girls than boys perceived themselves as obese/overweight and more parents of girls than of boys perceived them as such. Higher-educated parents were better at recognizing overweight/obesity among their children compared to less-educated parents. This study suggests an influence of parents’ SES characteristics on their perceptions of children’s weight status as well as on children’s own perceptions of their weight status.

    Full Text Available Using a nationally representative sample of 142 783 middle school (13–15 years old and high school (16–18 years old students in South Korea, this study examined whether (1 overweight and obesity are more likely to be associated with lower self-reported school performance; (2 overweight and obese students are more likely to enrol in a vocational high school as opposed to a general high school; (3 the association between obesity and poorer self-reported school performance is mediated through body image stress and health status. We found that excess weight was negatively associated with self-reported school performance among middle and general high school students, and that obese students had a higher probability of being enrolled in a vocational over a general high school. We did not find strong evidence on the mediating role of body image stress and health status.

    Full Text Available Low birth weight (LBW infant is susceptible to health problems since the infant born, during in the hospital and continue after discharge. The purpose of this study was to identify the influence of family empowerment on the health status of LBW infant. Action research using qualitative and quantitative method was used in this study. Qualitative approach was used to identify the experience of mothers of LBW infants as a data based for intervention development, and quantitative approach was used to evaluate the influence of family empowerment program on the health status of LBW infants. There were 7 participants, 20 mothers and their infants in the intervention group and 27 in the control group involved in this study. The study showed that family empowerment was effective in improving the immunization status and follow- up care attendance, reducing the frequency of acute care visits, increasing mothers' knowledge and skill in providing care. In conclusion, mothers need information on providing a proper care for LBW, and family empowerment can significantly improve maternal knowledge and health status of LBW infants.

    Science.gov (United States)

    Tan, Cin Cin; Chow, Chong Man

    2014-10-01

    This study examined whether engagement in fat talk would moderate the association between weight status (body mass index) and depression between female friends. Individuals' body mass index was significantly related to their own (actor effect) and friend's (partner effect) depression. For low-fat-talk friends, higher actor's body mass index was associated with higher actor's depression, but not for high-fat-talk friends. For high-fat-talk friends, higher actor's body mass index was associated with higher partner's depression, but not for low-fat-talk friends. Theoretical and practical implications are discussed.

    Single-serving packages (SSPs) may assist people in reducing consumption. Because overweight/obese individuals and individuals practicing dietary restraint may be more responsive to external food cues regarding an amount of food to consume, we examined whether weight and restraint status influence the relationship between package size and consumption. It was hypothesized that SSPs would reduce intake in overweight/obese individuals and individuals practicing dietary restraint compared with standard packages (STPs). Using a 2×2×2 (unrestrained/restrained×normal weight/overweight×SSP/STP) between-subjects design, 64 participants (aged 23.7±3.3 years; 81.3% white; 46.9% female), from June to October 2011, were randomly assigned to receive 20 oz pretzels packaged in SSPs or STPs, and were instructed to eat the pretzels ad libitum for 4 days. Each condition in the design contained eight participants. Total grams consumed was determined by subtracting postconsumption from preconsumption weight of packages provided. Using an analysis of variance for total grams of pretzels consumed, there was a significant interaction (P=0.01) between package size and weight status. Overweight/obese participants in the SSP condition ate fewer grams of pretzels than overweight/obese participants in the STP condition (107.0±101.9 g vs 204.4±144.9; Pobese individuals, fewer pretzels were consumed when packaged in SSPs compared with STPs. Thus, replacing STPs with SSPs may assist with reducing consumption in some overweight/obese individuals. Copyright © 2014 Academy of Nutrition and Dietetics. Published by Elsevier Inc.

    The purpose of the study was to test the hypothesis that socioeconomic status (SES) moderates the association between parental weight and changes in BMI from childhood to early adolescence. Participants included 428 twin children from 100 families with obese parents ("obese families") and 114 sociodemographically matched families with normal-weight parents ("lean families") who were assessed in their homes (age = 4.4). Follow-up study was conducted 7 years later (age = 11.2) on 346 children (81%). Complete data were available for 333 children. Family SES was indexed with maternal education. Children's weights and heights were measured to calculate BMI s.d. scores based on 1990 British norms. Overweight was defined as >91st BMI centile. In children with obese parents, BMI s.d. scores increased from 0.51 at age 4 to 1.06 at age 11. In children with lean parents, BMI s.d. scores decreased from 0.11 to 0.05. Prevalence of overweight remained stable from age 4 to 11 in children with lean parents (8% to 9%), but it more than doubled in children with obese parents (17% to 45%). There was a significant interaction between parental weight and family SES (P status from age 4 to 11; however, in children with obese parents, the increase in adiposity was significantly greater in lower SES families. These results suggest that parental leanness confers significant protection against development of overweight in children regardless of family SES, while parental obesity is an adverse prognostic sign, especially in lower SES families.

    Full Text Available Aim: To investigate differences in attitude toward physical activity in normal-weight, overweight, and obese adolescents. Materials and Methods: We conducted a cross-sectional survey carried out in 2009/2010. It concerned randomly selected schoolchildren of colleges of Sousse in seventh and ninth grade. The sample was composed of 4003 schoolchildren. A questionnaire was used to evaluate habits and perception of physical activity, and we took anthropometric measurements of height and weight. Results: Among schoolchildren who performed a recommended level of physical activity, there was no significant difference in perceptions according to weight status. However, among those who did not practice physical activity, obese participants had significantly less positive perception. Overweight and obesity significantly increase the risk of negative perception of physical activity practice among participants who do not do the recommended level of physical activity. However, this association becomes non significant among those who practice recommended level of physical activity. The same findings were observed after adjustment by age and sex. Conclusion: Negative attitudes among inactive children may favor the development of a vicious circle perpetuating physical inactivity among normal-weight and overweight children.

    Full Text Available Objective. To investigate the association of weight status with physical fitness among Chinese children. Methods. A total of 6929 children aged 6–12 years were selected from 15 primary schools of 5 provincial capital cities in eastern China. The height and fasting body weight were measured. The age-, sex-specific BMI WHO criteria was used to define underweight, overweight and obesity. Physical fitness parameters including standing broad jump, 50 m sprint, and 50 m∗8 shuttle run were tested. Results. The prevalence of underweight, overweight, and obesity was 3.1%, 14.9%, and 7.8%, respectively. Boys performed better than girls, and the older children performed better than their younger counterparts for all physical fitness tests. No significant difference in all three physical fitness tests were found between children with underweight and with normal weight, and they both performed better than their counterparts with overweight and obese in all three physical fitness tests. The likelihood of achieving good performance was much lower among overweight and obese children in comparison with their counterparts with normal weight (OR=0.13–0.54. Conclusions. An inverse association of obesity with cardiorespiratory fitness, muscle explosive strength, and speed was identified among Chinese children.

    Over the past 40 years, tourism-based economic development has transformed social and economic conditions in the Yucatan Peninsula, Mexico. We address how these changes have influenced anthropometric indicators of growth and nutritional status in Yalcoba, a Mayan farming community involved in the circular migration of labor in the tourist economy. Data are presented on stature and weight for children measured in 1938 in the Yucatan Peninsula and from 1987 to 1998 in the Mayan community of Yalcoba. In addition, stature, weight and BMI are presented for adults in Yalcoba based on clinic records. Childhood stature varied little between 1938 and 1987. Between 1987 and 1998 average male child statures increased by 2.6cm and female child statures increased by 2.7cm. Yet, 65% of children were short for their ages. Between 1987 and 1998, average child weight increased by 1.8kg. Child BMIs were similar to US reference values and 13% were considered to be above average for weight. Forty percent of adult males and 64% of females were overweight or obese. The anthropometric data from Yalcoba suggest a pattern of stunted children growing into overweight adults. This pattern is found elsewhere in the Yucatan and in much of the developing world where populations have experienced a nutrition transition toward western diets and reduced physical activity levels. 2010 Elsevier B.V.

    The purpose of this study was to assess weight status, dietary habits, physical activity, dietary beliefs, and nutrition knowledge among a sample of students from Central Michigan University. A cross-sectional survey was conducted among a sample of undergraduate students in Fall 2011 and Spring 2012 at Central Michigan University. Participating students completed an online questionnaire that included questions related to their eating habits, physical activity and lifestyle, dietary beliefs, and nutritional knowledge. Weight, height, and waist circumference were measured. Percentage body fat and visceral fat score were determined using a Tanita body composition analyser (SC-331S). Outcomes of this study indicated that 78% of female students were within the healthy weight range compared to 52% of male students. Visceral body fat and waist circumference scores were higher in males than in females. Most students showed 'satisfactory' dietary habits. Almost half of the students reported drinking two glasses of milk and consuming two cups of fruits and vegetables daily. Physical activity and lifestyle score indicated that most of the students were not physically active. Only 7% of students reported having a very active lifestyle, and 4% had quite good nutritional knowledge. The majority of students, particularly females, were within the healthy body weight range. Students' dietary habits were satisfactory. However, physical activity, students' knowledge of healthy and unhealthy diet habits, and nutritional knowledge needed improvement. Developing gender-specific programmes for promoting healthy lifestyle behaviours among students is recommended. © Royal Society for Public Health 2015.

    A large cohort of children was divided into two groups based on their parents' weight status. The high risk group had one or two overweight parent(s) (n = 92, 4.4 +/- 0.5 years), while the low risk group had no parent overweight (n = 95, 4.5 +/- 0.5 years). Weight of the two groups was similar at the start of the study but the high risk group gained marginally more weight over a one year period (P = 0.05). Although total energy intake was similar, the high risk group was consuming a larger percentage of energy from fat (P = 0.0004) and a smaller percentage from carbohydrate (P = 0.0002). Observed physical activity as similar for most levels but marginally higher for the stationary level and marginally lower in total activity in the high risk group. These results suggest a pattern that may lead to increased weight gain in a high risk group as they grow older.

    Full Text Available Abstract Background Body weight dissatisfaction is an important factor in preventing weight gain and promoting weight loss or maintenance. This study focuses on differences in the rates of body weight dissatisfaction among obese, preobese and normal weight women and men by socioeconomic status within a general adult population in Germany. Methods Data were analyzed from 4186 adults aged 25 to 74 who participated in a cross-sectional, representative population-based health survey (KORA S4, 1999–2001, Augsburg region/Germany. Body mass was measured anthropometrically and indexed following international standards. Among the 2123 women participating in the survey, 40.3% had a normal weight, 34.9% were preobese, and 24.8% were obese (compared to 25.9%, 51.4% and 22.6% among men, respectively. Body weight dissatisfaction, educational level, household income and occupational status were assessed by computer-aided personal interviewing. An index for socioeconomic status was calculated and categorized into quintiles. Multiple logistic regressions were performed to test for differences in the odds of body weight dissatisfaction across socioeconomic strata in normal weight, preobese and obese groups. Body mass index, age, family status, place of residence and health behaviors were adjusted for. Results Overall, being dissatisfied with one’s body weight was more prevalent in women (48.3% than in men (33.2%. In the normal weight group, no significant differences in the odds of being dissatisfied were found across socioeconomic groups among women or men. Among preobese men, compared to the lowest socioeconomic stratum, increased odds of being dissatisfied with one’s body weight were associated with the highest socioeconomic index group (OR = 2.3, 95% CI: 1.4–3.8, middle and high educational level (OR = 1.6, 95% CI: 1.1–2.3, and OR = 1.9, 95% CI: 1.3–3.7, high income (OR = 1.8, 95% CI: 1.2–2.7, and middle and high occupational

    The objective of this study was to examine the degree to which 2 measures of weight criticism, the Weight Criticism During Physical Activity (WCA) scale and the Perceptions of Teasing Scale (POTS), represent distinct constructs and in what circumstances each is most appropriately used. A community sample of 307 fourth and fifth graders completed these measures, as well as measures of health-related quality of life, physical activity engagement, and attitudes toward physical activity. Body mass index was also calculated. Results of confirmatory factor analysis indicated that the WCA scale and the POTS represented correlated but distinct constructs and related differently to measures of physical activity and weight status. Findings suggested that the WCA scale may be representing criticism regarding athletic competency, not criticism of weight status as described in the literature. The POTS subscales appear to be accurately described and used in the literature.

    Obesity is a risk factor for postmenopausal breast cancer incidence and premenopausal and postmenopausal breast cancer mortality, which may be explained by several metabolic and hormonal factors (sex hormones, insulin resistance, and inflammation) that are biologically related. Differential effects of dietary composition on weight loss and these metabolic factors may occur in insulin-sensitive vs. insulin-resistant obese women. To examine the effect of diet composition on weight loss and metabolic, hormonal and inflammatory factors in overweight/obese women stratified by insulin resistance status in a 1-year weight loss intervention. Nondiabetic women who were overweight/obese (n=245) were randomly assigned to a lower fat (20% energy), higher carbohydrate (65% energy) diet; a lower carbohydrate (45% energy), higher fat (35% energy) diet; or a walnut-rich (18% energy), higher fat (35% energy), lower carbohydrate (45% energy) diet. All groups lost weight at follow-up (Pdiet×time×insulin resistance status interaction was not statistically significant in the model for overall weight loss, although insulin sensitive women at 12months lost more weight in the lower fat vs. lower carbohydrate group (7.5kg vs. 4.3kg, P=0.06), and in the walnut-rich vs. lower carbohydrate group (8.1kg vs. 4.3kg, P=0.04). Sex hormone binding globulin increased within each group except in the lower carbohydrate group at 12months (Pdiet composition on weight loss depending on insulin resistance status. Prescribing walnuts is associated with weight loss comparable to a standard lower fat diet in a behavioral weight loss intervention.

    The US Department of Energy (DOE) is responsible for the disposition of transuranic (TRU) waste generated through national defense-related activities. Approximately 53,700 m{sup 2} of these wastes have been generated and are currently stored at government defense installations across the country. The Waste Isolation Pilot Plant (WIPP), located in southeastern New Mexico, has been sited and constructed to meet the criteria established by the scientific and regulatory community for the safe, long-term disposal of TRU and TRU-mixed wastes. This Compliance Status Report (CSR) provides an assessment of the progress of the WIPP Program toward compliance with long-term disposal regulations, set forth in Title 40 CFR 191 (EPA, 1993a), Subparts B and C, and Title 40 CFR {section}268.6 (EPA, 1993b), in order to focus on-going and future experimental and engineering activities. The CSR attempts to identify issues associated with the performance of the WIPP as a long-term repository and to focus on the resolution of these issues. This report will serve as a tool to focus project resources on the areas necessary to ensure complete, accurate, and timely submittal of the compliance application. This document is not intended to constitute a statement of compliance or a demonstration of compliance.

    Research has shown that parental feeding styles may influence children's food consumption, energy intake, and ultimately, weight status. We examine this relationship, among recent immigrants to the US. Given that immigrant parents and children are at greater risk for becoming overweight/obese with increased time in the US, identification of risk factors for weight gain is critical. Baseline data was collected on 383 mother-child dyads enrolled in Live Well, a community-based, participatory, randomized controlled lifestyle intervention to prevent weight gain in recent immigrant mothers. Socio-demographic information together with heights and weights were collected for both mother and child. Acculturation, behavioral data, and responses to the Caregiver's Feeding Styles Questionnaire (CFSQ) were also obtained from the mother. The children's average age was 6.2 ± 2.7 years, 58% male. Mothers had been in the country for an average of 6.0 ± 3.3 years, and are Brazilian (36%), Haitian (34%) and Latino (30%). Seventy-two percent of the mothers were overweight/obese, while 43% of the children were overweight/obese. Fifteen percent of mothers reported their feeding style as being high demanding/high responsive; 32% as being high demanding/low responsive; 34% as being low demanding/high responsive and 18% as being low demanding/low responsive. In bivariate analyses, feeding styles significantly differed by child BMIz-score, ethnic group, and mother's perceived stress. In multiple linear regression, a low demanding/high responsive feeding style was found to be positively associated (ß = 0.56) with a higher child weight as compared to high demanding/high responsive, controlling for known covariates (p = 0.01). Most mothers report having a low demanding/high responsive feeding style, which is associated with higher child weight status in this diverse immigrant population.

    Conflicting findings on associations between food and physical activity (PA) environments and children's weight status demand attention in order to inform effective interventions. We assess relationships between the food and PA environments in inner-city neighborhoods and children's weight status and address sources of conflicting results of prior research. Weight status of children ages 3-18 was assessed using parent-measured heights and weights. Data were collected from 702 children living in four low-income cities in New Jersey between 2009 and 2010. Proximity of a child's residence to a variety of food and PA outlets was measured in multiple ways using geo-coded data. Multivariate analyses assessed the association between measures of proximity and weight status. Significant associations were observed between children's weight status and proximity to convenience stores in the 1/4 mile radius (OR = 1.9) and with presence of a large park in the 1/2 mile radius (OR = 0.41). No associations were observed for other types of food and PA outlets. Specific aspects of the food and PA environments are predictors of overweight and obese status among children, but the relationships and their detection are dependent upon aspects of the geospatial landscape of each community.

    Full Text Available Abstract Background Breastfeeding has been shown consistently in observational studies to be protective of overweight and obesity in later life. This study aimed to investigate the association between breastfeeding duration and weight status in a national sample of Australian children and adolescents. Methods A secondary analysis of the 2007 Australian National Children's Nutrition and Physical Activity Survey data involving 2066, males and females aged 9 to 16 years from all Australian states and territories. The effect of breastfeeding duration on weight status was estimated using multivariate logistic regression analysis. Results Compared to those who were never breastfed, children breastfed for ≥6 months were significantly less likely to be overweight (adjusted odds ratio: 0.64, 95%CI: 0.45, 0.91 or obese (adjusted odds ratio: 0.51, 95%CI: 0.29, 0.90 in later childhood, after adjustment for maternal characteristics (age, education and ethnicity and children's age, gender, mean energy intake, level of moderate and vigorous physical activity, screen time and sleep duration. Conclusions Breastfeeding for 6 or more months appears to be protective against later overweight and obesity in this population of Australian children. The beneficial short-term health outcomes of breastfeeding for the infant are well recognised and this study provides further observational evidence of a potential long-term health outcome and additional justification for the continued support and promotion of breastfeeding to six months and beyond.

    To investigate precursors to gender-related obesity disparities by examining multiple family-level stress indices. Analyses was based on adolescents born between 1975 and 1991 to women from the 1979 National Longitudinal Study of Youth data set (N=4762). Three types of family-level stressors were captured from birth to age 15: family disruption and conflict, financial strain, and maternal risky health behaviors, along with a total cumulative risk index. Body mass index was constructed on reference criteria for children outlined by the Centers for Disease Control. Multivariate logistic regressions were conducted for the three types of family stressors and for the total cumulative index. The accumulation of family disruption and conflict and financial stress was positively related to female adolescents being overweight/obese. Childhood exposure to maternal risky health behaviors was positively associated with higher weight status for male adolescents. Total cumulative stress was related to overweight/obesity for females, but not males. Different family-level stress indices are associated with the weight status of female and male adolescents. Combining types of family-level stress into one cumulative index appears to mask these differences. Copyright © 2015 Elsevier Inc. All rights reserved.

    Full Text Available Background: State-issued identification cards are a promising data source for neighborhood-level obesity estimates. Methods: We used information from three million Oregon state-issued identification cards to compute age-adjusted estimates of average adult body mass index (BMI for each census tract in the state. We used multivariate linear regression to identify associations between weight status and population characteristics, food access, commuting behavior, and geography. Results: Together, home values, education, race, ethnicity, car commuting, and rural-urban commuting area (RUCA explained 86% of the variation in BMI among tracts. BMI was lower in areas with higher home values and greater educational attainment, and higher in areas with more workers commuting by car. Discussion: Our findings are consistent with other research on socioeconomic disparities in obesity. This demonstrates state-issued identification cards are a promising data source for BMI surveillance and may offer new insight into the association between weight status and economic and environmental factors. Public health agencies should explore options for developing their own obesity estimates from identification card data.

    To identify the association between pre-gestational nutritional status, maternal weight gain, and prenatal care with low birth weight (LBW) and prematurity outcomes in infants of adolescent mothers. Cross-sectional study with 542 pairs of adolescent mothers and their children attending a public maternity hospital in Rio de Janeiro. Data were collected from medical records. To determine the association between independent variables and the outcomes studied, odds ratio (OR) and a 95% confidence interval (CI) were estimated With respect to pre-pregnancy nutritional status of adolescents, 87% had normal weight, 1% were underweight, 10% were overweight, and 2% obese. Inadequate total gestational weight gain (72%) exceeded adequacy (28%). Birth weight was favored with greater gestational weight gain, and reduced with late onset of prenatal care. The comparison between the low birth weight and normal birth weight groups revealed significant differences between variable means: interval between the past pregnancy and current pregnancy (p = 0.022), pre-gestational weight (p = 0.018); pre-gestational body mass index (p prenatal visits. Birth weight was associated with inter-gestational interval, pre-pregnancy weight and body mass index before pregnancy. The minimum frequency of six prenatal care visits was a protective factor against LBW and prematurity.

    Individuals who are overweight or obese report body image concerns and lower self-esteem. However, little is known about the mechanisms underpinning these associations. The objective of this study was to test body-related shame and guilt as mediators in the association between weight status and self-esteem. Young adult participants (n = 790) completed assessments of self-esteem and body-related guilt and shame, and weight status indicators were measured by trained technicians. Findings from multiple mediation analyses suggest that body-related shame mediates the relationship between weight status and self-esteem. If replicated in longitudinal studies, these findings suggest that reducing body-related emotions may have important implications for improving self-esteem in clinical weight management.

    Full Text Available Abstract Objectives This study seeks to determine whether perception of weight status among the overweight has changed with the increasing overweight/obesity prevalence. Methods The perception of weight status was compared between overweight participants (BMI between 25.0–29.9 kg/m2 from NHANES III (1988–1994 and overweight participants from NHANES 1999–2004. Perception of weight status was assessed by asking participants to classify their weight as about the right weight, underweight or overweight. Comparisons were made across age groups, genders, race/ethnicities and various income levels. Results Fewer overweight people during the NHANES 1999–2004 survey perceived themselves as overweight when compared to overweight people during the NHANES III survey. The change in distortion between the survey periods was greatest among persons with lower income, males and African-Americans. Conclusion The increase in overweight/obesity between the survey years (NHANES III and NHANES 1999–2004 has been accompanied with fewer overweight people perceiving themselves as overweight.

    Full Text Available Aim of the study : We evaluated the effect of melatonin supplementation on the nutritional status of postmenopausal women. Material and methods: The study included 56 women (51-65 years and 25 healthy women (27-36 years. The emotional state was assessed using Hamilton Depression Rating Scale (HAM-D, the quality of sleep using Insomnia Severity Index (ISI. Body mass index (BMI and waist-hip ratio (WHR were also calculated. The patients were divided into 3 groups: group I (control – 25 women with normal body weight, group II – 26 postmenopausal women with normal body weight, group III – 30 postmenopausal women with high body weight. In women from group II and III, routine laboratory tests, levels of thyroid-stimulating hormone (TSH, 17-estradiol, prolactin, follicle-stimulating hormone (FSH and the concentration of 6-hydroxymelatonin sulphate (6-HMS in day/night urine fractions were determined. On the day of the examination, women remained on a liquid diet (1800 kcal. Next, a balanced diet of 1500 kcal and 5 mg of melatonin administration were recommended. The follow-up examinations were performed after 4, 8, 12, 16, 20 and 24 weeks. Results : The patients from groups II and III showed similar mild levels of anxiety and depression and a significant degree of sleep disorders. In group III, lower urinary 6-HMS excretion was observed at night. In both groups a negative correlation was found between urinary 6-HMS excretion and the degree of sleep disorders. After 24 weeks, a statistically significant improvement of quality of sleep was obtained. A negative correlation was detected between urinary 6-HMS excretion and BMI. Conclusion : Melatonin supplementation contributed to body weight reduction.

    Purpose This paper examines the relationship between family functioning (e.g. communication, closeness, problem solving, behavioral control) and adolescent weight status and relevant eating and physical activity behaviors. Methods Data are from EAT 2010 (Eating and Activity in Teens), a population-based study that assessed eating and activity among socioeconomically and racially/ethnically diverse youth (n = 2,793). Adolescents (46.8% boys, 53.2% girls) completed anthropometric assessments and surveys at school in 2009–2010. Multiple linear regression was used to test the relationship between family functioning and adolescent weight, dietary intake, family meal patterns, and physical activity. Additional regression models were fit to test for interactions by race/ethnicity. Results For adolescent girls, higher family functioning was associated with lower body mass index z-score and percent overweight, less sedentary behavior, higher intake of fruits and vegetables, and more frequent family meals and breakfast consumption. For adolescent boys, higher family functioning was associated with more physical activity, less sedentary behavior, less fast food consumption, and more frequent family meals and breakfast consumption. There was one significant interaction by race/ethnicity for family meals; the association between higher family functioning and more frequent family meals was stronger for non-white boys compared to white boys. Overall, strengths of associations tended to be small with effect sizes ranging from - 0.07 to 0.31 for statistically significant associations. Conclusions Findings suggest that family functioning may be protective for adolescent weight and weight-related health behaviors across all race/ethnicities, although assumptions regarding family functioning in the homes of overweight children should be avoided given small effect sizes.

    Purpose This study tested whether participation in organized physical activity (active vs. inactive) or weight status (normal weight vs. overweight or obese) independently relate to hildren’s cognition, using a matched-pairs design. Design and Methods Normal weight, active children (8–11 yrs, 5th–75th percentile BMI) were recruited from extracurricular physical activity programs while normal weight inactive (5th–75th percentile BMI) and overweight inactive children (BMI ≥85th percentile) were recruited from local Augusta, Georgia area schools. Measures included the Cognitive Assessment System, anthropometrics, and parent- and self-report of physical activity. Paired t-tests compared cognition scores between matched groups of normal weight active vs. normal weight inactive (N=24 pairs), normal weight inactive vs. overweight inactive (N=21 pairs), and normal weight active vs. overweight inactive children (N=16 pairs). Children in each comparison were matched for race, gender, age, and socioeconomic status. Results Normal weight active children had higher Planning (M±SD=109±11 vs. 100±11, p=.011) and Attention scores (108±11 vs. 100±11, p=013) than overweight inactive children. Normal weight inactive children had higher Attention scores than overweight inactive children (105±13 vs. 93±12, p=008). When compared to normal weight inactive children, normal weight active children had higher Planning (113±10 vs. 102±13, p=008) and marginally higher Attention scores (111±11 vs. 104±12, p=06). Conclusion Findings suggest independent associations of children’s weight status with selective attention, and physical activity with higher-order processes of executive function. PMID:26252198

    Objective The aim of this study was to investigate the prevalence of overweight/obesity among parents of children entering childhood obesity treatment and to evaluate changes in the parents’ weight statuses during their child’s treatment. Methods The study included parents of 1,125 children and adolescents aged 3–22 years, who were enrolled in a multidisciplinary childhood obesity treatment program. At baseline, weight and height of the parents were obtained by self-reported information and parental body mass index (BMI) was calculated. Weight and height of the children were measured in the clinic and BMI standard deviation scores were calculated. Furthermore, anthropometric data from parents of 664 children were obtained by telephone interview after a mean of 2.5 years of treatment (ranging 16 days to 7 years), and changes in parental BMI were analyzed. Results Data on changes in BMI were available in 606 mothers and 479 fathers. At baseline, the median BMI of the mothers was 28.1 kg/m2 (range: 16.9–66.6), and the median BMI of the fathers was 28.9 kg/m2 (range: 17.2–48.1). Seventy percent of the mothers and 80% of the fathers were overweight or obese at the time of their child’s treatment initiation. Both the mothers and fathers lost weight during their child’s treatment with a mean decrease in BMI in the mothers of 0.5 (95% CI: 0.2–0.8, p = 0.0006) and in the fathers of 0.4 (95% CI: 0.2–0.6, p = 0.0007). Of the overweight/obese parents, 60% of the mothers and 58% of the fathers lost weight during their child’s treatment. Conclusion There is a high prevalence of overweight/obesity among parents of children entering childhood obesity treatment. Family-based childhood obesity treatment with a focus on the child has a positive effect on parental BMI with both mothers and fathers losing weight.

    The obesity epidemic in the United States continues to increase. Because obesity tends to track over time, the increase in overweight among young children is of significant concern. A number of eating patterns have been associated with overweight among preschool-aged children. Recently, 100% fruit juice and sweetened fruit drinks have received considerable attention as potential sources of high-energy beverages that could be related to the prevalence of obesity among young children. Our aim was to evaluate the beverage intake among preschool children who participated in the National Health and Nutrition Examination Survey 1999-2002 and investigate associations between types and amounts of beverages consumed and weight status in preschool-aged children. We performed a secondary analysis of the data from the National Health and Nutrition Examination Survey 1999-2002, which is a continuous, cross-sectional survey of a nationally representative sample of the noninstitutionalized population of the United States. It included the collection of parent reported demographic descriptors, a 24-hour dietary recall, a measure of physical activity, and a standardized physical examination. The 24-hour dietary recall was obtained in person by a trained interviewer and reflected the foods and beverages that were consumed by the participant the previous day. The National Health and Nutrition Examination Survey food groups were classified on the basis of the US Department of Agriculture's Food and Nutrient Database for Dietary Studies. We reviewed the main food descriptors used and classified all beverages listed. One hundred percent fruit juice was classified as only beverages that contained 100% fruit juice, without sweetener. Fruit drinks included any sweetened fruit juice, fruit-flavored drink (natural or artificial), or drink that contained fruit juice in part. Milk included any type of cow milk and then was subcategorized by percentage of milk fat. Any sweetened soft drink

    This study assessed the disparity in nutritional status of adolescents between public and private schools in urban Gambia. This is a school-based cross-sectional study in six private and six public upper basic schools in urban Gambia. This study recruited 491 students from public and 469 students from private schools (13-15 years of age). The prevalence of stunting (WHO height-for-age Z school students and 4.5 % for private schools. After adjustment for children's sex, age, and family socioeconomic status, the differences in prevalence of stunting and underweight were significant between public and private schools. Private school students are more likely to be overweight/obese (WHO BMI-for-age Z > +1SD) (OR = 2.85, 95 % CI 1.55-5.22), but less likely to be thin (BMI-for-age Z school students. Children from lower income families had lower odds for overweight/obese than normal weight, compared to those from higher income families (OR = 0.34 [0.15-0.76]). Public and private schools in urban regions of the Gambia may face different nutritional challenges due to differences in school environment and resources.

Although there is hope of stemming the epidemic in childhood, no descriptions of children's dietary and physical activity (PA patterns are available for planning purposes. We describe the food and activity preferences and adult encouragement of active and sedentary behaviors for children 9–11 years in relation to weight status and the cultural context. Design. We used data from a pilot study preceding a large-scale ongoing study on the local drivers of the obesity epidemic among preadolescent children. PA, sedentary activity, and dietary intakes were assessed from recalls. Weight and height were measured. Setting. Barbados. Subjects. Sixty-two (62, 9–11-year-old school children. Results. Sugar-sweetened beverages provided 21% of energy consumed. Energy intake significantly explained BMI. Parents selected significantly more of children’s sedentary activities and encouraged mostly homework and chores (59%. Children’s self-selected school-based activity was significantly related to BMI. Conclusions. Childhood obesity prevention recommendations and research should focus on culture-specific practices that promote acquired taste for excess sugar and parent-child interactions regarding PA. Child influenced by school-based activity intervention may an important area for preventive intervention research.

    To investigate pathological findings in the susceptibility weighted imaging (SWI) of patients experiencing convulsive (CSE) or non-convulsive status epilepticus (NCSE) with focal hyperperfusion in the acute setting. Twelve patients (six with NCSE confirmed by electroencephalogram (EEG) and six patients with CSE with seizure event clinically diagnosed) underwent MRI in this acute setting (mean time between onset of symptoms and MRI was 3 h 8 min), including SWI, dynamic susceptibility contrast MR imaging (DSC) and diffusion-weighted imaging (DWI). MRI sequences were retrospectively evaluated and compared with EEG findings (10/12 patients), and clinical symptoms. Twelve out of 12 (100 %) patients showed a focal parenchymal area with pseudo-narrowed cortical veins on SWI, associated with focal hyperperfused areas (increased cerebral blood flow (CBF) and mean transit time (MTT) shortening), and cortical DWI restriction in 6/12 patients (50 %). Additionally, these areas were associated with ictal or postical EEG patterns in 8/10 patients (80 %). Most frequent acute clinical findings were aphasia and/or hemiparesis in eight patients, and all of them showed pseudo-narrowed veins in those parenchymal areas responsible for these symptoms. In this study series with CSE and NCSE patients, SWI showed focally pseudo-narrowed cortical veins in hyperperfused and ictal parenchymal areas. Therefore, SWI might have the potential to identify an ictal region in CSE/NCSE. (orig.)

    Full Text Available Behavioral and personality characteristics are factors that may jointly regulate body weight. This study explored the relationship between body mass index (BMI and self-reported behavioral and personality measures. These measures included eating behavior (based on the Three-Factor Eating Questionnaire- TFEQ (Stunkard and Messick, 1985, sensitivity to reward and punishment (based on the BIS/BAS Scales (Carver and White, 1994 and self-reported impulsivity (based on the Barratt Impulsiveness Scale-11 (Patton et al., 1995. We found an inverted U-shaped relationship between restrained eating and BMI. This relationship was moderated by the level of disinhibited eating. Independent of eating behavior, BIS and BAS responsiveness were associated with BMI in a gender-specific manner with negative relationships for men and positive relationships for women. Together, eating behavior and BIS/BAS responsiveness accounted for a substantial proportion of BMI variance (men: ~25%, women: ~32%. A direct relationship between self-reported impulsivity and BMI was not observed. In summary, our results demonstrate a system of linear and non-linear relationships between the investigated factors and BMI. Moreover, body weight status was not only associated with eating behavior (cognitive restraint and disinhibition, but also with personality factors not inherently related to an eating context (BIS/BAS. Importantly, these relationships differ between men and women.

We found an inverted U-shaped relationship between restrained eating and BMI. This relationship was moderated by the level of disinhibited eating. Independent of eating behavior, BIS and BAS responsiveness were associated with BMI in a gender-specific manner with negative relationships for men and positive relationships for women. Together, eating behavior and BIS/BAS responsiveness accounted for a substantial proportion of BMI variance (men: ∼25%, women: ∼32%). A direct relationship between self-reported impulsivity and BMI was not observed. In summary, our results demonstrate a system of linear and non-linear relationships between the investigated factors and BMI. Moreover, body weight status was not only associated with eating behavior (cognitive restraint and disinhibition), but also with personality factors not inherently related to an eating context (BIS/BAS).

The main purpose of this study was to evaluate the impact of nutrition claims and individual factors on perceived appetite sensations. According to a three (“healthy” versus “diet” (i.e., satiating versus “hedonic” by two (restrained or not restrained by two (normal-weight or overweight/obese by two (men versus women factorial design, 164 males and 188 females aged 18–65 were invited to taste an oatmeal-raisin snack in a blinded and ad libitum context. Visual analog scales (150 mm were used to evaluate appetite sensations before and over 1 h after consumption period. BMI and Restraint Scale were used to categorize participants according to their weight and restraint status. No main condition effect was observed for any of the four appetite sensations. However, subgroups analysis revealed significant differences among specific subgroups. A main effect of sex was also observed for all appetite sensations with men reporting higher levels of desire to eat, hunger and prospective food consumption, and lower levels of fullness than women. These findings highlight the importance of considering individual characteristics in interaction when studying appetite sensations.

    Many filamentous fungi from the genus Trichoderma are well known for their anti-microbial properties. Certain genes from Trichoderma spp. have been identified and transferred to plants for improving biotic and abiotic stress tolerance, as well for applications in bioremediation. Several Trichoderma genomes have been sequenced and many are in the pipeline, facilitating high throughput gene analysis and increasing the availability of candidate transgenes. This, coupled with improved plant transformation systems, is expected to usher in a new era in plant biotechnology where several genes from these antagonistic fungi can be transferred into plants to achieve enhanced stress tolerance, bioremediation activity, herbicide tolerance, and reduction of phytotoxins. In this review, we illustrate the major achievements made by transforming plants with Trichoderma genes as well as their possible mode of action. Moreover, examples of efficient application of genetically modified plants as biofactories to produce active Trichoderma enzymes are indicated.

    Full Text Available Emerging evidence from recent neuroimaging studies suggests specific food related behaviours contribute to the development of obesity. The aim of this review was to report the neural responses to visual food cues, as assessed by functional magnetic resonance imaging (fMRI, in humans of differing weight status. Published studies to 2014 were retrieved and included if they: used visual food cues, studied humans >18 years old, reported weight status, and included fMRI outcomes. Sixty studies were identified that investigated the neural responses of healthy weight participants (n=26, healthy weight compared to obese participants (n=17, and weight loss interventions (n=12. High calorie food images were used in the majority of studies (n=36, however, image selection justification was only provided in 19 studies. Obese individuals had increased activation of reward-related brain areas including the insula and orbitofrontal cortex in response to visual food cues compared to healthy weight individuals, and this was particularly evident in response to energy dense cues. Additionally, obese individuals were more responsive to food images when satiated. Meta-analysis of changes in neural activation post- weight loss revealed small areas of convergence of activation across studies in brain areas related to emotion, memory and learning such as the cingulate gyrus, lentiform nucleus and precuneus.Differential activation patterns to visual food cues were observed between obese, healthy weight and weight loss populations. Future studies require standardisation of dietetic variables and fMRI outcomes to enable more direct comparisons between studies.

    Consumption of 100% fruit juice remains controversial for its potential adverse impact on weight and displacement of essential foods in the diets of children. A systematic review of the literature published from 1995-2013 was conducted using the PubMed database to evaluate associations between intake of 100% fruit juice and weight/adiposity and nutrient intake/adequacy among children of 1 to 18 years of age. Weight status outcome measures included body mass index (BMI), BMI z-score, ponderal index, obesity, weight gain, adiposity measures, and body composition. Nutrient outcome measures included intake and adequacy of shortfall nutrients. Data extraction and analysis was conducted according to the Academy of Nutrition and Dietetics Evidence Analysis Process. Twenty-two studies on weight status provided evidence that did not support an association between 100% fruit juice consumption and weight/adiposity in children after controlling for energy intake. Limited evidence from eight studies suggests that children consuming 100% fruit juice have higher intake and adequacy of dietary fiber, vitamin C, magnesium, and potassium. Differences in methodology and study designs preclude causal determination of 100% fruit juice as sole influencer of weight status or nutrient intake/adequacy of shortfall nutrients. In context of a healthy dietary pattern, evidence suggests that consumption of 100% fruit juice may provide beneficial nutrients without contributing to pediatric obesity.

    Nitrogen (N) plays a key role in the plant life cycle. It is the main plant mineral nutrient needed for chlorophyll production and other plant cell components (proteins, nucleic acids, amino acids). Crop yield is affected by plant N status. Thus, the optimization of nitrogen fertilization has become the object of intense research due to its environmental and economic impact. This article focuses on reviewing current methods and techniques used to determine plant N status. Kjeldahl digestion and Dumas combustion have been used as reference methods for N determination in plants, but they are destructive and time consuming. By using spectroradiometers, reflectometers, imagery from satellite sensors and digital cameras, optical properties have been measured to estimate N in plants, such as crop canopy reflectance, leaf transmittance, chlorophyll and polyphenol fluorescence. High correlation has been found between optical parameters and plant N status, and those techniques are not destructive. However, some drawbacks include chlorophyll saturation, atmospheric and soil interference, and the high cost of instruments. Electrical properties of plant tissue have been used to estimate quality in fruits, and water content in plants, as well as nutrient deficiency, which suggests that they have potential for use in plant N determination.

The results showed that the plant density significantly influenced the number of flowers per plant and flower weight. The largest number of flowers per plant was recorded in the plant density B (13.2 and the lowest (9.87 in the plant density C. The lowest flower weight was recorded in the plant density C (1.31 g and was statistically lower than the flower weight in the plant densities A (1.42 g and B (1.38 g. The plant density significantly influenced the number of flowers on side branches, being the highest in the plant density B. The diameter of the marigold flower was not significantly influenced by the plant density. During the experiment, a total of 13 harvests were achieved. The greatest number of flowers per plant was harvested in the eighth, ninth and tenth harvest, while the largest flower weight was measured in the fifth and twelfth harvest. On the average, the number of flowers per plant / harvest was 11.63 and the weight of flowers was 1.38 g. Diameter of marigold flowers ranged from 2.89 cm to 3.59 cm in the thirteenth and the third harvest, respectively. The number of flowers on side branches per plant / harvest was 11.61.

    In India, indigenous remedies have been used in treatment of sexual dysfunction since the time of Charaka and Sushruta. Plants have been always an exemplary source of drugs and many of the currently available drugs have been derived directly or indirectly from them. An aphrodisiac is defined as an agent that arouses sexual desire. Erectile dysfunction or sexual dysfunction (ED or SD) or male impotence is defined as the inability of a man to achieve and maintain an erection sufficient for mutually satisfactory intercourse with his partner. Sexual health and function are important determinants of quality of life. To overcome the problem of male sexual (or) erectile dysfunction, various Indian natural aphrodisiac plants potentials were preferred. The ethnobotanical information reports that about 200 plants possess aphrodisiac potential. Out of several Indian medicinal plants, 33 plants were reviewed. In this review, studies on Indian medicinal plants were reviewed and their possible therapeutic applications were discussed. This review discusses about aphrodisiac potential of Indian medicinal plants, its botanical name, common name, family, extract, models used, part used and references, which are helpful for researchers to develop new herbal aphrodisiac formulations. In the recent years, interest in drugs of plant origin has been progressively increased.

    Full Text Available Abstract Background Socioeconomically disadvantaged mothers are at high risk of obesity, yet the aetiology of obesity in this group remains poorly understood. The aim of this study was to examine the perceived personal, social and physical environmental factors associated with resilience to obesity among mothers from socioeconomically disadvantaged neighbourhoods. Methods Survey data were provided by a cohort of 1840 women aged 18-46 years with dependent children (aged 0-18 years from 40 urban and 40 rural socioeconomically disadvantaged neighbourhoods across Victoria, Australia. Mothers responded to a number of questions relating to personal, social and environmental influences on their physical activity and eating habits. Mothers' weight status was classified as healthy weight (BMI: 18.5-24.99, overweight (BMI: 25-29.99 or obese (BMI: 30+. Results Mothers' weight status was bivariably associated with factors from all three domains (personal, social and physical environmental. In a multivariable model, mothers' perceived ability to make time for healthy eating (OR = 1.34 and physical activity (OR = 1.11 despite family commitments, and the frequency with which families ate healthy low-fat foods with mothers (OR = 1.28 remained significantly positively associated with healthy weight status. The frequency with which families encouraged eating healthy low-fat foods remained negatively associated (OR = 0.81 with weight status; ie greater encouragement was associated with less healthy weight status. Conclusions Drawing on the characteristics of mothers resilient to obesity might assist in developing intervention strategies to help other mothers in socioeconomically disadvantaged neighbourhoods to manage their weight. Such strategies might focus on planning for and prioritising time for healthy eating and physical activity behaviours, and including family members in and encouraging family mealtimes.

    Asthma is a common disease that is rising in prevalence worldwide with the highest prevalence in industrialized countries. Asthma affect about 300 million people worldwide and it has been estimated that a further 100 million will be affected by 2025. Since the ancient times, plants have been exemplary sources of medicine. Current asthma therapy lack satisfactory success due to adverse effect, hence patients are seeking complementary and alternative medicine to treat their asthma. Ayurveda and other Indian literature mention the use of plants in various human ailments. India has about 45 000 plant species and among them several thousand are claimed to possess medicinal properties. Researches conducted in the last few decades on the plants mentioned in ancient literature or used traditionally for asthma have shown antiasthmatic, antihistaminic and antiallergic activity. This review reveals that some plants and their extract have antiasthmatic, antihistaminic, anticholinergic and antiallergic activity.

    There is scarce information on the relative importance of socio-economic factors in determining the adolescent anthropometric measurements. The objective of this study was to examine the effects of economic status, education level, and food consumption on the height and weight of community adolescents in Nepal. The study was done in the communities of the Kathmandu Valley area in Nepal. All together 426 unmarried adolescent girls aged 14-19 y were selected. The adolescents were interviewed regarding socioeconomic background (education, occupation and property possessions) and frequency of foods consumption. Height and weight were determined and BMI was calculated. Z-scores of height-for-age and weight-for-age were calculated based on the WHO/NCHS standard to avoid bias by age. The adolescents participating in the survey were categorized into three groups using the various indicators of economic status: Low Economic Status (LES) group, Middle Economic Status (MES) group and High Economic Status (HES) group. The Z-scores of height and weight were significantly lower in the LES group than in the MES and HES groups (peducation level even under the condition of controlling economic level (peducation levels (chi2=22.4, df=6, peducation level was interpreted to be due to the outcome of the higher frequency of milk consumption. This study indicated that education was a more important factor affecting the height of the adolescents via improved food habits even under adverse economic conditions.

    Objective This study examined weight status as a moderator of the relationship between motivation (controlled, autonomous, regulatory), emotional social support (parents, peers) and moderate-to-vigorous physical activity (MVPA) in underserved adolescents (ethnic minority, low-income). Methods Participants from the Active by Choice Today Trial (n = 1,416; 54% girls, 73% African American, 52% overweight/obese) completed baseline measures, including height and weight, psychosocial surveys, and 7-day accelerometry estimates. Weight status was defined by body mass index z-score (zBMI). Results Weight status moderated the effects of controlled, autonomous, and regulatory motivation on MVPA, such that these variables were more strongly associated with MVPA in adolescents with lower versus higher zBMI scores. Conclusions A better understanding of why motivation is not related to MVPA in underserved youth with a higher weight status is needed. Future pediatric obesity treatment in underserved youth may need to move beyond motivation into environmental factors associated with long-term behavior change. PMID:23378172

    The terroir analysis, aiming to achieve a better use of environmental features with respect to plant requirement and wine production, needs to be strongly rooted on hydropedology. In fact, the relations between wine quality and soil moisture regime during the cropping season is well established. The ZOViSA Project (Viticultural zoning at farm scale) tests a new physically oriented approach to terroir analysis based on the relations between the soil-plant water status and wine quality. The project is conducted in southern Italy in the farm Quintodecimo of Mirabella Eclano (AV) located in the Campania region, devoted to quality Aglianico red wine production (DOC). The soil spatial distribution of study area (about 3 ha) was recognized by classical soil survey and geophysics scan by EM38DD; then the soil-plant water status was monitored for three years in two experimental plots from two different soils (Cambisol and Calcisol). Daily climate variables (temperature, solar radiation, rainfall, wind), daily soil water variables (through TDR probes and tensiometers), crop development (biometric and physiological parameters), and grape must and wine quality were monitored. The agro-hydrological model SWAP was calibrated and applied in the two experimental plots to estimate soil-plant water status in different crop phenological stages. The effects of crop water status on crop response and wine quality was evaluated in two different pedo-systems, comparing the crop water stress index with both: crop physiological measurements (leaf gas exchange, leaf water potential, chlorophyll content, LAI measurement), grape bunches measurements (berry weight, sugar content, titratable acidity, etc.) and wine quality (aromatic response). Finally a "spatial application" of the model was carried out and different terroirs defined.

    The objective of this cohort study was to explore relationships among the home food environment (HFE), child/parent characteristics, diet quality, and measured weight status among 699 child-parent pairs from King County, WA, and San Diego County, CA. HFE variables included parenting style/feeding practices, food rules, frequency of eating out, home food availability, and parents' perceptions of food costs. Child dietary intake was measured by 3-day recall and diet quality indicators included fruits and vegetables, sweet/savory snacks, high-calorie beverages, and Dietary Approaches to Stop Hypertension (DASH) score. Individual linear regression models were run in which child BMI z score and child diet quality indicators were dependent variables and HFE variables and child/parent characteristics were independent variables of interest. Fruit and vegetable consumption was associated with parental encouragement/modeling (β=.68, P<0.001) and unhealthful food availability (-0.27, P<0.05); DASH score with food availability (healthful: 1.3, P<0.01; unhealthful: -2.25, P<0.001), food rules (0.45, P<0.01), and permissive feeding style (-1.04, P<0.05); high-calorie beverages with permissive feeding style (0.14, P<0.01) and unhealthful food availability (0.21, P<0.001); and sweet/savory snacks with healthful food availability (0.26, P<0.05; unexpectedly positive). Children's BMI z score was positively associated with parent's use of food restriction (0.21, P<0.001), permissive feeding style (0.16, P<0.05), and concern for healthy food costs (0.10, P<0.01), but negatively with verbal encouragement/modeling (-0.17, P<0.05), and pressure to eat (-0.34, P<0.001). Various HFE factors associated with parenting around eating and food availability are related to child diet quality and weight status. These factors should be considered when designing interventions for improving child health.

    To study the association of weight status with food insecurity (FI) and socio-economic status (SES) in Azeri and Kurd ethnic groups living in Urmia city, North-Western Iran. In this cross-sectional study, 723 participants (427 women and 296 men) aged 20-64 years old, from two ethnic groups (445 Azeri and 278 Kurd), were selected through a combination of cluster, random and systematic sampling methods. Demographic and socio-economic characteristics were assessed by a valid questionnaire, and household food security status was analyzed using an adapted household food insecurity access scale through face-to-face interviews at homes. General and central obesities were measured and evaluated using standard methods. Based on the findings, moderate-to-severe FI, as well as low SES, was more dominant in Kurds, compared to Azeris. After adjusting for confounders, being female (OR = 4.33, CI 95%: 2.35-7.97) and moderate-to-severe FI (OR = 2.00, CI 95%: 1.01-3.97) in Azeris and being female (OR = 5.39, CI 95%: 2.28-12.23) and higher total cost of household/capita (OR = 1.005, CI 95%: 1.002-1.009) in Kurds were related to higher odds of general obesity while low (OR = 0.41, CI 95%: 0.18-0.91) and moderate (OR = 0.13, CI 95%: 0.02-0.60) education levels were linked to lower chance of general obesity. Furthermore, the chance of central obesity was lower in Azeris with high educational levels (OR = 0.64, CI 95%: 0.21-0.94), females (OR = 0.72, CI 95%: 0.34-0.86), home owners (OR = 0.56, CI 95%: 0.31-0.91) and females Kurds (OR = 0.60, CI 95%: 0.37-0.97) with moderate-to-severe FI and higher total income per capita. In contrast, the chance of central obesity increased in Kurds with increased age (OR = 1.06, CI 95%: 1.02-1.10) and total cost of household per capita (OR = 1.004, CI 95%: 1.000-1.008). These findings show that the association between moderate-to-severe FI and risk of general/central obesity varies in Azeris, compared to

    Obesity and fitness have been associated with older adults' physical independence. We aimed to investigate the independent and combined associations of physical fitness and adiposity, assessed by body mass index (BMI) and waist circumference (WC) with the projected ability for physical independence. A total of 3496 non-institutionalized older adults aged 65 and older (1167 male) were included in the analysis. BMI and WC were assessed and categorized according to established criteria. Physical fitness was evaluated with the Senior Fitness Test and individual test results were expressed as Z-scores. Projected ability for physical independence was assessed with the 12-item composite physical function scale. Logistic regression was used to estimate the odds ratio (OR) for being physically dependent. A total of 30.1 % of participants were classified as at risk for losing physical independence at age 90 years. Combined fitness and fatness analysis demonstrated that unfit older adults had increased odds ratio for being physically dependent in all BMI categories (normal: OR = 9.5, 95 %CI = 6.5-13.8; overweight: OR = 6.0, 95 %CI = 4.3-8.3; obese: OR = 6.7, 95 %CI = 4.6-10.0) and all WC categories (normal: OR = 10.4, 95%CI = 6.5-16.8; middle: OR = 6.2, 95 %CI = 4.1-9.3; upper: OR = 7.0, 95 %CI = 4.8-10.0) compared to fit participants that were of normal weight and fit participants with normal WC, respectively. No increased odds ratio was observed for fit participants that had increased BMI or WC. In conclusion, projected physical independence may be enhanced by a normal weight, a normal WC, or an increased physical fitness. Adiposity measures were not associated with physical independence, whereas fitness is independently related to physical independence. Independent of their weight and WC status, unfit older adults are at increased risk for losing physical independence.

    Although pre-pregnancy weight status and early pregnancy lipid profile are known to influence blood pressure course during pregnancy, little is known about how these two factors interact. The association between pre-pregnancy weight status and blood pressure course during pregnancy was assessed in the prospective ABCD study and the role (independent/mediating/moderating) of early pregnancy lipid profile in this association was determined. We included 2500 normal weight (lipids [median (IQR): 13 (12-14) weeks of gestation] and blood pressure during pregnancy [mean (SD) = 10 (2.3)]. Lipids (triglycerides, total cholesterol, apolipoprotein A1, apolipoprotein B and free fatty acids) were divided into tertiles. Multilevel piecewise linear spline models were used to describe the course of systolic and diastolic blood pressure (SBP/DBP) in four time periods during gestation for overweight and normal weight women. Both SBP (5.3 mmHg) and DBP (3.9 mmHg) were higher in overweight compared to normal weight women and this difference remained the same over all four time periods. The difference in SBP and DBP was not mediated or moderated by the lipid profile. Lipid profile had an independent positive effect on both SBP (range 1.3-2.2 mmHg) and DBP (0.8-1.1 mmHg), but did not change blood pressure course. Both pre-pregnancy weight status and early pregnancy lipid profile independently increase blood pressure during pregnancy. Improving pre-pregnancy weight status and early pregnancy lipid profile might result in a healthier blood pressure course during pregnancy.

    To describe the association between weight status and sexual practices among 18- to 19-year-old women. We analyzed a population-based longitudinal study of 18- to 19-year-old women residing in a Michigan county at cohort inception. Weekly journal surveys measured sexual practices, including contraceptive behaviors. Outcomes included proportion of weeks with a partner, proportion of weeks with sexual intercourse, number of partners, average length of relationships, proportion of weeks with contraception use, and proportion of weeks where contraception was used consistently. We examined 26,545 journal surveys from 900 women over the first study year. Ordinary least squares regression models for each outcome examined differences by weight status, controlling for sociodemographic characteristics. The mean proportion of weeks in which adolescents reported sexual intercourse was 52%; there was no difference by weight status. Among weeks in which adolescents reported sexual activity, obese adolescents had a lower proportion of weeks where any contraception was used compared with normal weight adolescents (84% vs 91%, P = .011). Among weeks in which adolescents reported sexual activity and contraceptive use, obese adolescents had a lower proportion of weeks with consistent contraceptive use (68% vs 78%, P = .016) and oral contraceptive pill use (27% vs 45%, P = .001) compared with normal weight adolescents. All other relationships by weight status were not statistically significant. In this longitudinal study, obese adolescent women were less likely to use contraception, and less likely to use it consistently when compared with normal weight peers. Findings suggest obesity may be an important factor associated with adolescent women's sexual behavior. Copyright © 2015 The Authors. Published by Elsevier Inc. All rights reserved.

    Adolescents in modern societies spend about 3 h per day in front of small recreational screens. The present study aims at investigating the relationships between screen time and different indicators of overweight. In addition, associations with the self-concept of physical attractiveness and perceived weight status will be examined. In a total sample of 1228 students (47.5% girls) aged 12-17 years (M = 13.74, SD = 0.68) cross-sectional associations were determined by conducting multiple linear regression analyses. Screen time showed a significant positive dose-response relationship with body mass index percentile, waist circumference, body fat, waist-to-height-ratio, and a negative association with self-concept of physical attractiveness independent of age, gender and moderate to vigorous physical activity. Thus, screen time seems to be associated with adolescent overweight, abdominal obesity, and body dissatisfaction. Reducing adolescents' screen time could be a promising approach for primary prevention of obesity and for the promotion of a positive physical self-concept.

    Diffusion-weighted magnetic resonance imaging (DWI) is used to detect changes in the distribution of water molecules in regions affected by various pathologies. Like other conditions, ictal epileptic activity, such as status epilepticus (SE), can cause regional vasogenic/cytotoxic edema that reflects hemodynamic and metabolic changes. This study describes the electroclinical and neuroimaging findings in 10 patients with partial SE whose DWI evaluation disclosed periictal changes related to sustained epileptic activity. In this retrospective study we selected 10 patients with partial SE of different etiologies (six acute symptomatic SE; four with previous epilepsy and concomitant precipitating factors) who underwent video-EEG (electroencephalography) monitoring and a DWI study during the periictal phase. We analyzed ictal electroclinical features and DWI changes in the acute phase and during the follow-up period. DWI images revealed significant signal alterations in different brain regions depending on the location of ictal activity. DWI changes were highly concordant with the electroclinical findings in all 10 patients. As the SE resolved and the clinical conditions improved, DWI follow-up showed that the signal alterations gradually disappeared, thereby documenting their close relationship with ictal activity. This study confirms the usefulness of DWI imaging in clinical practice for a more accurate definition of the hemodynamic/metabolic changes occurring during sustained epileptic activity.

    The Expanded Disability Status Scale (EDSS) is the most widely employed ordinal disability scale in multiple sclerosis (MS). However, how far apart the individual EDSS levels are along the disability spectrum has not been formally quantified. The objective of this paper is to generate refined disability weights (DWs) for each of the ordinal EDSS levels. We performed the person trade-off (PTO) procedure to derive DWs of five representative EDSS categories (2, 4, 6, 7 and 9), and DWs of the remaining EDSS categories were assigned by linear interpolation. The modified Delphi process was used to achieve consensus among raters. DWs were 0.021 for EDSS 2, 0.199 for EDSS 4, 0.313 for EDSS 6, 0.617 for EDSS 7, and 0.926 for EDSS 9. Panel members achieved a high degree of consensus for each DW, as indicated by low coefficients of variation. Our DWs confirmed that EDSS is an ordinal scale with highly variable intervals. The availability of DW for each EDSS level allows direct comparison of each MS outcome state with other health states and provides a foundation for the estimation of the disability-adjusted life-years lost of individual patients. © The Author(s) 2013.

    Full Text Available Purpose. To identify whether non-overweight students were different from their overweight or obese peers with respect to diet, suboptimal meal behaviours, and physical activity using a self-administered web-based survey. Methods. 4097 adolescents living in Alberta, Canada completed Web-SPAN (Web Survey of Physical Activity and Nutrition. Students were classified as overweight or obese, and differences were described in terms of nutrient intakes, physical activity, and meal behaviours. Results. Non-overweight students consumed significantly more carbohydrate and fibre, and significantly less fat and high calorie beverages, and had a higher frequency of consuming breakfast and snacks compared to overweight or obese students. Both non-overweight and overweight students were significantly more active than obese students. Conclusions. This research supports the need to target suboptimal behaviours such as high calorie beverage consumption, fat intake, breakfast skipping, and physical inactivity. School nutrition policies and mandatory physical education for all students may help to improve weight status in adolescents.

    The present study examined whether the cross-sectional association between body dissatisfaction and low self-esteem varies across gender, age, body weight status, race/ethnicity, and socioeconomic status (SES). We also examined the association longitudinally. A school-based survey of eating, weight, and related attitudes was conducted with a diverse sample of adolescents aged 11-18 years (N = 4,746). Height and weight were measured in the schools at Time 1. Participants were resurveyed through mails 5 years later (Time, 2; N = 2,516). The relationship between body dissatisfaction and self-esteem was strong and significant in both boys and girls (all p values body dissatisfaction and self-esteem was strong, but did vary across weight status, race/ethnicity, and SES (all p values = .0001-.03). The relationship was nonsignificant in underweight girls (p = .36), and weaker but still significant among black, Asian, and low SES group girls (all p values body dissatisfaction and self-esteem are strongly related among nearly all groups of adolescents. This suggests the importance of addressing body image concerns with adolescents of all backgrounds and ages.

    Melatonin (N-acetyl-5-methoxytryptamine) is a ubiquitous molecule with pleiotropic actions in different organisms. It performs many important functions in human, animals, and plants; these range from regulating circadian rhythms in animals to controlling senescence in plants. In this review, we summarize the available information regarding the presence of melatonin in different plant species, along with highlighting its biosynthesis and mechanisms of action. We also collected the available information on the effects of melatonin application on commercially important crops to improve their growth and development. Additionally, we have identified many new aspects where melatonin may have possible roles in plants, for example, its function in improving the storage life and quality of fruits and vegetables, its role in vascular reconnection during the grafting process and nutrient uptake from roots by modifying root architecture. Another potentially important aspect is the production of melatonin-rich food crops (cereals, fruits, and vegetables) through combination of conventional and modern breeding approaches, to increase plant resistance against biotic and abiotic stress, leading to improved crop yields, and the nutraceutical value of produce to solve food security issues.

    Full Text Available Maintaining plant diversity on tropical islands is a priority for biodiversity conservation. Hainan Island, located in the northern tropics, is the second largest island in China with high plant diversity. Several updated plant lists of local flora have been published after decades of field investigations. In this paper, we investigated the plant diversity on Hainan Island by conducting extensive field surveys and a literature review. Results indicated that, as of December 2015, there were 6,036 vascular plants recorded on Hainan Island with voucher specimens or practical materials. Among these species, 1,220 species were revised as synonymously, 4,579 species were wild (including 483 endemic and 512 rare and endangered species, 163 were naturalized species (including 57 invasive species and 1,294 species were cultivated species. Since the publication of Flora Hainanica in 1964–1977, a large proportion of newly recorded species were mainly wild or introduced species, and accounted for 35.9% and 75.9% of their corresponding totals, respectively.

    AP and VP were measured in cucumbers under water sufficiency and water stress. The results indicated that, the AP would be evoked by electrical impulse, for water-stressed cucumber, its amplitude could reached more than 40 mV which was obviously greater than that (about 10-20 mV) of plant under well-watered,and no VP came out. Along with the intensity of light increased, the VP appeared going-up trend, and accompanied by evidently spiking electrical signal, for plant under water stress, the VP increased more clearly, but the change of spiking amplitude of AP (about 3 mY) was rather smaller than that (8-10 mY) of plant under well-watered.

    Physical functioning and psychological resilience in adulthood is shaped during adolescence. Self-reported health-related quality of life (HRQoL) assessments during this life phase are important first-hand accounts of their well-being. This study aimed, firstly, to identify differences in HRQoL according to gender, ethnicity, socio-economic status and weight status; and secondly, to examine associations between weight status and HRQoL among an urban sample of multi-ethnic adolescents in Kuala Lumpur, Malaysia. A cross-sectional study involving 652 adolescents (aged 13 years) was conducted in Kuala Lumpur. Weight and height were measured. Body mass index z-scores were categorized according to the International Obesity Task Force criteria. HRQoL was assessed using the Malay version of the Pediatric Quality of Life Inventory 4.0 Generic Core Scales. Univariate analyses of differences in HRQoL according to gender, ethnicity (Malays, Chinese and Indians), maternal education level and weight status were performed. Complex samples general linear model was used to examine the associations between HRQoL and weight status, adjusted for confounders. Female adolescents reported significantly lower emotional functioning scores (mean, 95% confidence interval: 59.25, 57.33-61.17). When the three main ethnic groups were studied, Malay adolescents scored significantly lower emotional functioning scores (59.00, 57.13-60.87) compared with their Chinese peers. Adolescents with tertiary-educated mothers reported lower emotional functioning scores (57.45, 53.85-61.06) compared with those with primary-educated mothers. Obese adolescents reported poorer HRQoL scores with significantly impaired physical and social functioning after controlling for confounders. These findings detected disparities in HRQoL among the adolescents when gender, ethnicity, maternal education level and weight status were considered. Further studies should address these health inequalities by implementing gender

    Dietary intake, vitamin status and oxidative stress were evaluated in 17 elite male boxers. Ten of them frequently reduced body weight rapidly before competitions (Weight Loss Group) and 7 did not practice rapid weight loss (Control Group). Food record checklists, blood samples for determination of vitamin status and plasma glutathione levels were obtained during a week of weight maintenance, a pre-competition week and a post-competition week. The average dietary intakes in both groups were 33 ± 8 kcal·kg(-1), 3.7 ± 1.1 g·kg(-1) carbohydrates, 1.5 ± 0.4 g·kg(-1) protein, 1.2 ± 0.4 g·kg(-1) fat and 2.2 ± 1.0 L water per day (excluding pre-competition week in Weight Loss Group). Energy (18 ± 7 kcal·kg(-1)), carbohydrate (2.2 ± 0.8 g·kg(-1)), protein (0.8 ± 0.4 g·kg(-1)), fat (0.6 ± 0.3 g·kg(-1)) and water (1.6 ± 0.6 L) consumption (P-values <0.001) and intakes of most vitamins (P-values < 0.05) were significantly reduced during the pre-competition week in the Weight Loss Group. In both groups, the intakes of vitamins A, E and folate were below recommended values throughout the three periods; however, blood vitamin and plasma glutathione levels did not change significantly. Our findings indicate a low-caloric and low-carbohydrate diet in elite boxers, regardless of participating in rapid weight loss or not. Apparently, the pre-competitional malnutitrition in the Weight Loss Group did not induce alterations in the vitamin and glutathione status.

    Increasing demand for energy production with low impact on the environment and minimised fuel consumption can be met with high efficient coal fired power plants with advanced steam parameters. An important key to this improvement is the development of high temperature materials with optimised mechanical strength. Based on the results of more than ten years of development a coal fired power plant with an efficiency above 50 % can now be realised. Future developments focus on materials which enable an efficiency of 52-55 %. (orig.) 25 refs.

    Obesity rates among school-age children remain high. Access to energy-dense foods at home, in schools, in stores, and restaurants around homes and schools is of concern. Research on the relationship between food environment around schools and students' weight status is inconclusive. This study examines the association between weight status of middle and high school students and proximity to a comprehensive set of food outlets around schools. Deidentified nurse-measured heights and weights data were obtained for 12,954 middle and high school students attending 33 public schools in four low-income communities in New Jersey. Geocoded locations of supermarkets, convenience stores, small grocery stores, and limited-service restaurants were obtained from commercial sources. Random-effect regression models with robust standard errors were developed to adjust for unequal variances across schools and clustering of students within schools. Proximity to small grocery stores that offered some healthy options (e.g., five fruits, five vegetables, and low-fat/skim milk) and supermarkets was associated with healthier student weight status. Having a small grocery store within 0.25 mile of school and an additional such store within that radius was associated with a lower BMI z-score (pstores, that offer healthy food options and supermarkets around middle and high schools is a potential strategy for improving weight outcomes among students.

    Compared measures of physical activity and dietary habits used in the Health Is Power (HIP) study, and described the associations of physical activity and dietary habits among African American and Hispanic or Latino women, adjusted for weight status. Cross-sectional baseline data were compared for community dwelling, healthy African American (N = 262) and Hispanic or Latina women (N = 148) who participated in HIP. Physical activity was measured using the International Physical Activity Questionnaire (IPAQ) long form, the Check And Line Questionnaire (CALQ) log and accelerometry. Dietary habits were measured using NCI 24-h recall screeners, vegetable and fruit (VF) logs and the NCI Diet History Questionnaire (DHQ). Differences in physical activity and dietary habits were assessed using simultaneous 2 (ethnicity) × 3 (weight status) ANCOVAs adjusted for age and socioeconomic status. Women (M age = 44.4 ± 10.9 years) were obese (M = 34.0 ± 9.7 kg/m2), did not meet physical activity guidelines as measured by accelerometry (M = 19.4 ± 19.1 min MVPA/day) and ate few VF (M = 2.8 ± 2.7 servings/day). DHQ variables differed by weight status. IPAQ was associated with CALQ, and CALQ with accelerometry (P < .05). IPAQ was not associated with accelerometry. Regardless of ethnicity, normal weight women did more physical activity, reported more VF consumption, and consumed more fat calories than overweight and obese women (Ps < .05). African American women did more MVPA than Hispanic or Latino women (P < .001). Relationships between behaviors and weight status suggest accelerometry and DHQ are preferable, regardless of ethnicity; and studies may capture different domains of physical activity and dietary habits depending on measure used.

    Obesity is associated with lower concentrations of serum 25-hydroxyvitamin D; however, uncertainty exists as to the direction of causation. To date, meta-analyses of randomized controlled vitamin D-supplementation trials have shown no effect of raising circulating vitamin D on body weight, although several weight-loss-intervention trials have reported an increase in circulating vitamin D after weight reduction. We undertook a systematic review and meta-analysis of randomized and nonrandomized controlled trials to determine whether weight loss compared with weight maintenance leads to an increase in serum 25-hydroxyvitamin D. A systematic search for controlled weight-loss-intervention studies published up to 31 March 2016 was performed. Studies that included participants of any age with changes in adiposity and serum 25-hydroxyvitamin D as primary or secondary outcomes were considered eligible. We identified 4 randomized controlled trials (n = 2554) and 11 nonrandomized controlled trials (n = 917) for inclusion in the meta-analysis. Random assignment to weight loss compared with weight maintenance resulted in a greater increase in serum 25-hydroxyvitamin D with a mean difference of 3.11 nmol/L (95% CI: 1.38, 4.84 nmol/L) between groups, whereas a mean difference of 4.85 nmol/L (95% CI: 2.59, 7.12 nmol/L) was observed in nonrandomized trials. No evidence for a dose-response effect of weight loss on the change in serum 25-hydroxyvitamin D was shown overall. Our results indicate that vitamin D status may be marginally improved with weight loss in comparison with weight maintenance under similar conditions of supplemental vitamin D intake. Although additional studies in unsupplemented individuals are needed to confirm these findings, our results support the view that the association between obesity and lower serum 25-hydroxyvitamin D may be due to reversed causation with increased adiposity leading to suboptimal concentrations of circulating vitamin D. This trial was

    The efficiency of the photoautotrophic element as part of bio-engineering life-support systems is determined substantially by lighting regime. The artificial light regime optimization complexity results from the wide range of plant physiological functions controlled by light: trophic, informative, biosynthetical, etc. An average photosynthetic photon flux density (PPFD), light spectral composition and pulsed light effects on the crop growth and plant physiological status were studied in the multivariate experiment, including 16 independent experiments in 3 replicates. Chinese cabbage plants (Brassica chinensis L.), cultivar Vesnianka, were grown during 24 days in a climatic chamber under white and red light-emitting diodes (LEDs): photoperiod 24 h, PPFD from 260 to 500 µM/(m ^{2}*s), red light share in the spectrum varying from 33% to 73%, pulsed (pulse period from 30 to 501 µs) and non-pulsed lighting. The regressions of plant photosynthetic and biochemical indexes as well as the crop specific productivity in response to the selected parameters of lighting regime were calculated. Developed models of crop net photosynthesis and dark respiration revealed the most intense gas exchange area corresponding to PPFD level 450 - 500 µM/(m ^{2}*s) with red light share in the spectrum about 60% and the pulse length 30 µs with a pulse period from 300 to 400 µs. Shoot dry weight increased monotonically in response to the increasing PPFD and changed depending on the pulse period under stabilized PPFD level. An increase in ascorbic acid content in the shoot biomass was revealed when increasing red light share in spectrum from 33% to 73%. The lighting regime optimization criterion (Q) was designed for the vitamin space greenhouse as the maximum of a crop yield square on its ascorbic acid concentration, divided by the light energy consumption. The regression model of optimization criterion was constructed based on the experimental data. The analysis of the model made it

Evidence for the relationship between dietary intake and body weight among Malaysian children is limited, with the impact of energy intake misreporting rarely being considered. This paper describes the dietary intakes of urban Malay children in comparison to national recommendations and by weight status. This cross-sectional Family Diet Study (n = 236 was conducted in five national primary schools in Malaysia (August 2013–October 2014. Data on socio-demographics, anthropometrics, 24-h dietary recalls, and food habits were collected from Malay families, consisting of a child aged 8 to 12 years and their main caregiver(s. Multivariable analyses were used to assess dietary intake-body weight relationships. The plausibility of energy intake was determined using the Black and Cole method. Approximately three in 10 Malay children were found to be overweight or obese. The majority reported dietary intakes less than national recommendations. Children with obesity had the lowest energy intakes relative to body weight (kcal/kg compared to children in other weight categories (F = 36.21, p < 0.001. A positive moderate correlation between energy intake and weight status was identified (r = 0.53, p < 0.001 after excluding energy intake mis-reporters (n = 95, highlighting the need for the validation of dietary assessment in obesity-related dietary research in Malaysia.

    Emerging evidence from recent neuroimaging studies suggests that specific food-related behaviors contribute to the development of obesity. The aim of this review was to report the neural responses to visual food cues, as assessed by functional magnetic resonance imaging (fMRI), in humans of differing weight status. Published studies to 2014 were retrieved and included if they used visual food cues, studied humans >18 years old, reported weight status, and included fMRI outcomes. Sixty studies were identified that investigated the neural responses of healthy weight participants (n = 26), healthy weight compared to obese participants (n = 17), and weight-loss interventions (n = 12). High-calorie food images were used in the majority of studies (n = 36), however, image selection justification was only provided in 19 studies. Obese individuals had increased activation of reward-related brain areas including the insula and orbitofrontal cortex in response to visual food cues compared to healthy weight individuals, and this was particularly evident in response to energy dense cues. Additionally, obese individuals were more responsive to food images when satiated. Meta-analysis of changes in neural activation post-weight loss revealed small areas of convergence across studies in brain areas related to emotion, memory, and learning, including the cingulate gyrus, lentiform nucleus, and precuneus. Differential activation patterns to visual food cues were observed between obese, healthy weight, and weight-loss populations. Future studies require standardization of nutrition variables and fMRI outcomes to enable more direct comparisons between studies. PMID:25988110

    To evaluate the awareness and knowledge about weight status and its management. A 1 d cross-sectional survey. Basic anthropometric assessments (weight, height, BMI and waist circumference) and a self-administered questionnaire were considered. Nineteen Clinical Nutrition or Endocrinology and Metabolic Disorders Units or Dietetics Services in the Italian region of Lombardy. All adults attending the 'Obesity Day' initiative. A total of 914 participants (605 female and 309 male) were recruited. Although most of the participants (83·5 %) considered obesity to be a disease, 38·5 % were likely to misperceive their weight status. In particular, 38·8 % of normal-weight adults believed themselves to be overweight, whereas 71·1 % and 37·5 % of classes I and II/III obese adults classified themselves as being overweight and mildly obese, respectively. However, most of the overweight (90·2 %), mildly (96·8 %) and moderately/severely obese adults (99·1 %) recognized the need to lose weight. In all, 37·8 % of the sample underestimated the role of physical activity in weight management. Interestingly, only 17·2 % of dieters (previous or current) declared being advised by their doctor to lose weight. Multivariate models revealed that higher age, low education and higher BMI were important determinants of poor weight control and management. In addition, previous dieting appeared not to provide better knowledge, whereas the role of physical activity was recognized mainly by those practising it. The present study suggests that in Italy knowledge about weight management should be improved not only in the general population but also among health-care professionals. To confirm this finding, there is now the rationale for a nationally representative survey. New educational programmes can be designed on the basis of the information collected.

    Objective The relative importance of loss of control and overeating in the relationship between binge eating and eating-related and general psychopathology has been debated in the literature. This study assessed the prevalence and correlates of overeating with and without loss of control within a diverse, population-based sample of adolescents. Method A highly diverse (81.1% non-White) sample of adolescents (n=2,793) from EAT-2010 (Eating and Activity in Teens) completed self-report questionnaires assessing eating-related psychopathology, substance use, non-suicidal self-injury, depressive symptoms, and self-esteem. Results Overeating without loss of control was reported by 6.9% of girls and 5.0% of boys, while 9.6% of girls and 6.3% of boys reported overeating with loss of control (binge eating). Overall, overeating (with or without loss of control) was positively associated with unhealthy or extreme weight control behaviors, dieting, non-suicidal self-injury, lower body satisfaction and self-esteem, and higher depressive symptoms relative to no overeating. Among girls, binge eating was associated with unhealthy or extreme weight control behaviors, lower self-esteem, and higher depressive symptoms relative to overeating without loss of control, while in boys, binge eating was associated with greater cigarette usage, lower body satisfaction, and greater depressive symptoms than overeating without loss of control (although cigarette usage was comparable in boys reporting binge eating and no overeating). Discussion Any overeating, with or without loss of control, was associated with multiple adverse correlates among adolescents. Loss of control was uniquely associated with multiple health indicators, further highlighting its importance as a marker of severity of overeating. PMID:26368333

    It is unclear whether Supplemental Nutrition Assistance Program (SNAP) or National School Lunch Program (NSLP) participation modifies the relationship between food insecurity and obesity in children. Data were included for 4,719 children aged 9-17 years who participated in the National Health and Nutrition Survey between 2003-2004 and 2011-2012. Linear regression was used to examine the relationship between household food security (full, marginal, low, and very low) and BMI percentile. Adjusted models were also stratified by SNAP and NSLP participation. There was no significant overall relationship between household food security and BMI percentile. In SNAP non-participants, there was no apparent overall relationship between BMI percentile and household food security. However, BMI percentile in children from households with low food security was significantly higher than that of children from fully food-secure households (risk difference [RD]=5.95, 95% CI=1.11, 10.80). Among SNAP participants, there was no significant relationship between household food security and BMI percentile. By NSLP participation category, there was a non-significant trend toward increasing BMI percentile with decreasing household food security in those reporting two or fewer (RD=1.75, 95% CI= -0.79, 4.29) and two to three (RD=1.07; 95% CI= -1.74, 3.89) lunches/week. There was no apparent relationship between household food security and BMI percentile in those reporting four or more lunches/week. Although the overall relationship between household food security and weight status in school-aged children was not statistically significant, there was some evidence that the relationship may differ by SNAP or NSLP participation, suggesting the need for more research.

    Full Text Available Seed circulation among farmers, which is embedded in composite social networks, is a key process in the dynamics of seed systems that shape crop diversity. We analyzed the daily circulation of biological objects, i.e., cultivated plants (31 species, 284 landraces, within a community of first-generation migrants (16 households, 30 persons living on the island of Vanua Lava in the South Pacific archipelago nation of Vanuatu. By combining participant observation, ethnobiological inventories, and social network analysis, we investigated how farmer social status and plant biocultural value affect plant circulation. Plant biocultural value was estimated by referring to their local classification according to uses, cultivation practices, growing environments, and biological properties. An aggregate plant circulation network (577 events and three subnetworks (i.e., for starchy, side dish, or snack food categories sharing the same 30 nodes were analyzed using exponential random graph models. Evidence that farmer social status influences the patterns of plant circulation was found through the distribution of structural parameters of the network, including: dyadic reciprocity; in-degree, out-degree, and their correlation; triadic cycling; and transitivity. At the scale of the aggregate network, direct or indirect reciprocity was not observed. Instead, a high out-degree (i.e., being a more frequent giver and a negative correlation between in-degree and out-degree both confer prestige and reinforce hierarchy. These results suggest that some of the social dynamics of the Melanesian-type Big Man political system may persist, even though the system itself no longer exists in traditional form. Moreover, based on our comparative analysis of the three subnetworks, farmer social status appears to influence greatly the circulation of plants with high biocultural value while having little influence on plants with low biocultural value.

    The effect of wood ash, sawdust, ground cocoa husk, spent grain and rice bran upon root development, ash content, pod yield and nutrient status and soil fertility for okra (Abelmoschus esculentum L NHAe 47 variety) was studied. The five organic fertilizer treatments were compared to chemical fertilizer (400kg/ha/crop NPK 15-15-15) and unfertilized controls in four field experiments replicated four times in a randomized complete block design. The results showed that the application of 6tha(-1) of plant residues increased (Ppod N, P, K, Ca, Mg and ash; root length; and pod yield of okra in all four experiments relative to the control treatment. For instance, spent grain treatment increased the okra pod yield by 99%, 33%, 50%, 49%, 65% and 67% compared to control, NPK, wood ash, cocoa husk, rice bran and sawdust treatments respectively. In the stepwise regression, out of the total R(2) value of 0.83 for the soil nutrients to the pod yield of okra; soil N accounted for 50% of the soil fertility improvement and yield of okra. Spent grain, wood ash and cocoa husk were the most effective in improving okra pod weight, pod nutrients, ash content, root length and soil fertility whereas the rice bran and sawdust were the least effective. This was because the spent grain, wood ash and cocoa husk had lower C/N ratio and higher nutrient composition than rice bran and sawdust, thus, the former enhanced an increase in pod nutrients, composition for better human dietary intake, increased the root length, pod weight of okra and improved soil fertility and plant nutrition crop. The significance of the increases in okra mineral nutrition concentration by plant residues is that consumers will consume more of these minerals in their meals and monetarily spend less for purchasing vitamins and mineral supplement drugs to meet health requirements. In addition, the increase in plant nutrition and soil fertility would help to reduce the high cost of buying synthetic inorganic fertilizers and

    The chemical composition of plant leaves often reflects environmental contamination. The authors analyzed images of plant leaves to investigate the regional radioactivity ecology resulting from the 2011 accident at the Fukushima No. 1 nuclear power plant, Japan. The present study is not an evaluation of the macro radiation dose per weight, which has been performed previously, but rather an image analysis of the radioactive dose per leaf, allowing the capture of various gradual changes in radioactive contamination as a function of elapsed time. In addition, the leaf analysis method has potential applications in the decontamination of food plants or other materials.

    Prevention of body dissatisfaction development is critical for minimizing adverse effects of poor body esteem on eating behaviors, self-esteem, and overall health. Research has examined body esteem and its correlates largely in pre-adolescents and adolescents; however, important questions remain about factors influencing body esteem of younger children. The main purpose of this study was to test moderation by children's gender and weight status of the relation of maternal controlling feeding practices to 1st graders' body esteem. The Body Esteem Scale (BES) and anthropometric measurements were completed during one-on-one child interviews at school. Mothers completed the Child Feeding Questionnaire (restriction, monitoring, concern, self-assessed maternal weight). A total of 410 mother/child dyads (202 girls) participated. Percent of children classified as overweight (BMI-for-age ≥85th) was: girls - 29%; boys - 27%. Gender moderated the relation between restriction and body esteem (β = -.140, p = .05), with maternal restriction predicting body esteem in girls but not boys. The hypothesized three-way interaction among gender, child weight status, and monitoring was confirmed. Monitoring was significantly inversely related to body esteem only for overweight/obese girls (b = -1.630). The moderating influence of gender or gender and weight status on the link between maternal feeding practices and body esteem suggests the importance of body esteem interventions for girls as early as first grade.

    This study sought to examine the association between the parent-reported appetite of a child and the child's weight status after 2 years. The design was a 2-year prospective study. A total of 531 Korean children aged 11 to 12 years were followed up for change in weight status (persistent overweight, persistent nonoverweight, recently overweight, recently nonoverweight) between 2001 and 2003 after the measurement of their appetite (low, moderate, and high) using a questionnaire administered to their parents in 2001. Weight status of each child was determined based on the criteria of body mass index (BMI) recommended by the International Obesity Task Force reference. The statistical analyses performed were multiple logistic regression analysis with adjustment for parental factors (parents' weight and height, education level, and income) and the child's characteristics (baseline BMI, physical activity, and television viewing). Main outcome measures were child's mean BMI and weight status, and the proportions of overweight children at the baseline and at the end of the follow-up were greater among those children whose parents reported that they had high appetites (Pchildren with a low appetite, the odds ratio for overweight at the end of follow-up was 3.7 (95% confidence interval 1.2 to 11.7) in children with a high appetite. Subgroup analysis of overweight children at baseline showed that the risk of being persistently overweight over the 2-year follow-up was 5.5 times (95% confidence interval 1.1 to 27.5) higher in children with a high appetite than in those with a low appetite. There was a strong association between the parent-reported appetite of a child and being overweight after 2 years. Identifying children with higher appetites and targeting them for lifestyle modification may provide an effective way of reducing the incidence of childhood overweight.

    Purpose The present study examined whether the cross-sectional association between body dissatisfaction and low self-esteem varies across gender, age, body weight status, race/ethnicity, and SES. We also examined the association longitudinally. Methods A school-based survey of eating, weight, and related attitudes was conducted with a diverse sample of adolescents aged 11–18 years (N = 4,746). Height and weight were measured in the schools at Time 1. Participants was resurveyed by mail five years later (Time 2, N = 2,516). Results The body dissatisfaction/self-esteem association was strong and significant in both boys and girls (p’sself-esteem relationship was strong, but did vary across weight status, race/ethnicity, and SES (p’s .0001–.03). The relationship was non-significant in underweight girls (p=.36), and weaker but still significant among black, Asian, and low SES girls (all p’s adolescents grew older. Conclusions Findings indicate that body dissatisfaction and self-esteem are strongly related among nearly all groups of adolescents. This suggests the importance of addressing body image concerns with adolescents of all backgrounds and ages. PMID:20708569

    Full Text Available OBJECTIVE: To assess the prevalence of low body weight/thinness, overweight and obesity in a representative sample of children and adolescents from a Brazilian region with low economic development. METHODS: A total of 982 girls and 986 boys, aged seven to 17 years old and assisted by Segundo Tempo Program, from Montes Claros, Minas Gerais, Brazil, were included in the study. Low body weight/thinness, overweight and obesity were defined based on body mass cut-off indexes recommended by the International Obesity Task Force. The prevalence of the nutritional status according to sex and age was compared by chi-square test. RESULTS: In girls, the frequency of low body weight/thinness, overweight and obesity was 4.1, 18.4 and 3.8%, respectively; in boys, these percentages were 6.3, 13.2 and 2.9%, respectively. The low body weight/thinness for girls raised from 2.7% (7-10 years old to 5.5% (15-17 years old; the body weight excess (overweight and obesity decreased from 30.1 to 16.2% for the same age groups. In boys, the corresponding trends were from 3.2 to 9.4% for low body weight/thinness, and from 23.4 to 9.2%, for body weight excess. CONCLUSIONS: The data indicate that, even in a region with low economic status, the body weight excess was the main problem associated with nutritional health. The high overweight and obesity prevalence rates indicate the need of public policies for promoting healthy feeding behaviors and physical activity.

    Metal exposure is known to induce the production and secretion of substances, such as aliphatic low molecular weight organic acids (ALMWOAs), into the rhizosphere by plant roots. Knowledge on this matter is extensive for soil plants but still considerably scarce regarding marsh plants roots adapted to high salinity media. Phragmites australis and Halimione portulacoides, two marsh plants commonly distributed in European estuarine salt marshes, were used to assess the response of roots of both species, in terms of ALMWOAs exudation, to Cu, Ni and Cd exposure (isolated and in mixture since in natural environment, they are exposed to mixture of metals). As previous studies were carried out in unrealistic and synthetic media, here a more natural medium was selected. Therefore, in vitro experiments were carried out, with specimens of both marsh plants, and in freshwater contaminated with two different Cu, Ni and Cd concentrations (individual metal and in mixture). Both marsh plants were capable of liberating ALMWOAs into the surrounding medium. Oxalic, citric and maleic acids were found in P. australis root exudate solutions and oxalic and maleic acids in H. portulacoides root exudate solutions. ALMWOA liberation by both plants was plant species and metal-dependent. For instance, Cu affected the exudation of oxalic acid by H. portulacoides and of oxalic and citric acids by P. australis roots. In contrast, Ni and Cd did not stimulate any specific response. Regarding the combination of all metals, H. portulacoides showed a similar response to that observed for Cu individually. However, in the P. australis case, at high metal concentration mixture, a synergetic effect led to the increase of oxalic acid levels in root exudate solution and to a decrease of citric acid liberation. A correlation between ALMWOAs exudation and metal accumulation could not be established. P. australis and H. portulacoides are considered suitable metal phytoremediators of estuarine impacted areas

    Full Text Available Knee osteoarthritis (OA is a leading cause of functional disability among American adults. Obesity is a strong independent risk factor for OA. While research emphasizes the role of obesity in the OA-physical function relationship, the extent to which weight status impacts salient physical, health, and pain measures in older, knee OA patients is not well delineated. The primary aim of this study was to assess differences in mobility performance (stair climb and 400-meter walk, mobility-related self-efficacy, pain symptoms (WOMAC, and measures of accelerometer-determined physical activity (PA as a function of weight status. Analysis of covariance was conducted to examine differences on the dependent variables. Obese class III patients were outperformed by their counterparts on nearly every measure of mobility, mobility-related self-efficacy, and the assessment of pain symptoms. These outcomes did not differ among other weight comparisons. Normal weight subjects outperformed classes I, II, and III counterparts on most measures of PA (engagement in moderate or greater PA and total weekly steps. Additionally, overweight participants outperformed obese class II participants and obese class I participants outperformed obese classes II and III participants on total weekly steps. Collectively, these findings underscore the meaningful differences observed in relevant OA outcomes as a function of increasing levels of body weight.

    To determine the effect of infant feeding practices on postpartum weight change among HIV-infected and -uninfected women in South Africa. In a non-randomised intervention cohort study of antiretroviral therapy-naïve women in South Africa, infants were classified as exclusive (EBF), mixed (MF) or non-breastfed (NBF) at each visit. We analysed infant feeding cumulatively from birth to 5 months using 24-hour feeding history (collected weekly for each of the preceding 7 days). Using generalised estimating equation mixed models, allowing for repeated measures, we compared postpartum weight change (kg) from the first maternal postpartum weight within the first 6 weeks (baseline weight) to each subsequent visit through 24 months among 2340 HIV-infected and -uninfected women with live births and at least two postpartum weight measurements. HIV-infected (-0.2 kg CI: -1.7 to 1.3 kg; P = 0.81) and -uninfected women (-0.5 kg; 95% CI: -2.1 to 1.2 kg; P = 0.58) had marginal non-significant weight loss from baseline to 24 months postpartum. Adjusting for HIV status, socio-demographic, pregnancy-related and infant factors, 5-month feeding modality was not significantly associated with postpartum weight change: weight change by 24 months postpartum, compared to the change in the reference EBF group, was 0.03 kg in NBF (95% CI: -2.5 to +2.5 kg; P = 0.90) and 0.1 kg in MF (95% CI: -3.0 to +3.2 kg; P = 0.78). HIV-infected and -uninfected women experienced similar weight loss over 24 months. Weight change postpartum was not associated with 5-month breastfeeding modality among HIV-infected and -uninfected women. © 2014 John Wiley & Sons Ltd.

    The objective of the TVA Aquatic Plant Management Program is to support in an environmentally and economically responsible manner, the balanced multiple uses of the water resource of the Tennessee Valley. This is accomplished by following an integrated approach to prevent introduction and spread of noxious species, documenting occurrence and spread of existing species, and suppressing or eliminating problems in designated high use areas. It is not the TVA objective, nor is it biologically feasible and prudent to eliminate all aquatic vegetation. Aerial photography, helicopter reconnaissance, and field surveys are used to assess distributions and abundance of various aquatic macrophytes. Water level fluctuations are supplemented by herbicide applications to control undesirable vegetation. Investigations are conducted to evaluate water level fluctuation schemes, as well as biological, mechanical, and alternative chemical control techniques which offer potential for more environmentally compatible and cost-effective management operations.

    To examine cross-sectional and longitudinal associations between weight status and measures of risk and protective factors in youth. Participants included 3010 students (72.1% white, 27.9% nonwhite), with a baseline mean age of 12.7 years from the Teens Eating for Energy and Nutrition at School (TEENS) study. Surveys were administered in grades 7 and 8. Cross-sectional and longitudinal mixed-effects regression analyses were conducted to determine the association between body mass index z-score percentiles (BMI) and risk and protective factors (including substance use, depression, fighting, optimism, and spirituality). Only depression was associated with BMI at the beginning of grade 7. However, by the end of grade 8, binge drinking, alcohol, tobacco, and other drug (ATOD) use, fighting, and depression were all cross-sectionally associated with BMI. Longitudinally, BMI in grade 7 did not predict risk and protective factors in grade 8. However, ATOD use, fighting, depression, and optimism in grade 7 predicted BMI in grade 8. This study suggests there is a notable co-occurrence of unhealthy factors (including weight status, ATOD use, depression) which appears to develop during the critical transition period through early adolescence. Specifically, earlier ATOD use, depression, increased fighting, and decreased optimism may lead to unhealthy increases in weight status, whereas early indicators of increased weight status do not appear to predict increases in these factors. This work yields important insights into the causal mechanisms underlying adolescent behavior patterning and the progression with which these unhealthy risk factor profiles are adopted during this critical age.

    Depression may be a risk factor for overweight status, but mechanisms involved in this relationship are unclear. This study explored behavioral factors involved in the relationship between adolescent depression symptoms and adult overweight status. A population-based cohort of female participants in Project EAT (n=1035) was followed over 10 years and reported on psychological functioning, weight status and eating and activity patterns in early/middle adolescence (1999=Time 1; T1), middle adolescence/early young adulthood (2004=Time 2; T2) and early/middle young adulthood (2009=Time 3; T3). Structural equation models were fit which included T1 depression scores predicting overweight status at T3, with T2 fruit and vegetable consumption, moderate-to-vigorous physical activity and binge eating examined as mediators. There were small but significant effects of T1 depression scores predicting an increased likelihood of T3 overweight status (standardized estimate=0.038; P=0.007), and of T2 binge eating mediating the relation between T1 depression and T3 overweight status (standardized indirect effect estimate=0.036; P=0.009). Binge eating may be one pathway to overweight among depressed females, suggesting that recognition and treatment of eating pathology in individuals with depression may help prevent overweight. Examination of other behavioral (and non-behavioral) factors explaining the relationship between depression and overweight is warranted.

    According to the International Classification of Functioning, Disability and Health model endorsed by the World Health Organization, participation in everyday activities is integral to normal child development. However, little is known about the influence of motor ability and weight status on physical activity participation in children with developmental coordination disorder (DCD). This study aimed to (1) compare motor performance, weight status and pattern of out-of-school activity participation between children with DCD and those without; and (2) identify whether motor ability and weight status were determinants of participation patterns among children with DCD. We enrolled 81 children with DCD (boys, n = 63; girls, n = 18; mean age, 8.07 ± 1.5 years) and 67 typically developing children (boys, n = 48; girls, n = 19; mean age, 8.25 ± 1.6 years). Participation patterns (diversity, intensity, companionship, location, and enjoyment) were evaluated with the Children Assessment of Participation and Enjoyment. Motor ability was evaluated with the Movement Assessment Battery for Children, second edition (MABC-2). Other factors that may influence participation such as age, gender, and body weight were also recorded. Analysis of variance was used to compare outcome variables of the two groups, and significant determinants of activity participation were identified by multiple regression analysis. Children with DCD participated in fewer activities (i.e., limited participation diversity) and participated less frequently (i.e., limited participation intensity) than their typically developing peers; however, companionship, location of participation, and enjoyment level did not differ between the two groups. Children in the DCD group demonstrated significantly worse motor ability as assessed by the MABC-2. Further, a greater proportion of children in the DCD group were in the overweight/obese category compared with their typically developing peers. After accounting for the

    This study assesses differences in adiposity, aerobic fitness, and lifestyle characteristics in preschoolers according to their weight status and sports club (SC) participation. As part of the Ballabeina study, 600 randomly selected preschoolers (mean age 5.1 ± 0.6 years; 50.2% girls) were analyzed. Body composition was measured by bioelectrical impedance, aerobic fitness by the 20-meter shuttle run test, and physical activity by accelerometers. Eating habits, media use, and SC participation were assessed by questionnaires. Overweight children (Swiss national percentiles) and children not participating in SC had both lower aerobic fitness and higher % body fat compared to their respective counterparts (all p ≤ 0.028). In addition, children not participating in SC were less physically active, had more media use, and ate less healthy compared to children participating in SC (all p ≤ 0.023). Controlling for parental sociocultural determinants attenuated differences in % body fat, in physical activity, and in eating habits. Aerobic fitness differs both according to weight status and SC participation in preschoolers. Furthermore, in view of the many differences in lifestyle behaviors, SC participation at this age could represent a more discriminatory indicator of healthy lifestyle characteristics than weight status.

    Little is known about how screen-based sedentary behavior at home and in preschool influences children's health and activity patterns. The current study examined the individual and cumulative influence of TV viewing at home and in preschool on children's physical activity (PA) and weight status. Children (n = 339) attending 16 preschools in South Carolina were grouped into high and low TV groups based on parent report of children's TV viewing at home and director report of TV use/rules in preschool. T-tests and mixed model ANOVAs examined differences in weight status and PA (min/hr) by high and low TV groups. Results revealed that children who were classified as High TV both at home and in pre- school had significantly lower levels of moderate-to-vigorous PA compared with their Low TV counterparts (8.3 (0.3) min/hr vs. 7.6 (0.2) min/hr, p TV groups at home or in preschool when examined individually. These findings demonstrate the importance of total environmental TV exposure on preschooler's PA. Longitudinal and observational research to assess preschoolers' cumulative screen-based sedentary behavior and its relationship with PA and weight status is needed.

    Over the last decades, a decline in motor skills and in physical activity and an increase in obesity has been observed in children. However, there is a lack of data in young children. We tested if differences in motor skills and in physical activity according to weight or gender were already present in 2- to 4-year-old children. Fifty-eight child care centers in the French part of Switzerland were randomly selected for the Youp'là bouge study. Motor skills were assessed by an obstacle course including 5 motor skills, derived from the Zurich Neuromotor Assessment test. Physical activity was measured with accelerometers (GT1M, Actigraph, Florida, USA) using age-adapted cut-offs. Weight status was assessed using the International Obesity Task Force criteria (healthy weight vs overweight) for body mass index (BMI). Of the 529 children (49% girls, 3.4 ± 0.6 years, BMI 16.2 ± 1.2 kg/m2), 13% were overweight. There were no significant weight status-related differences in the single skills of the obstacle course, but there was a trend (p = 0.059) for a lower performance of overweight children in the overall motor skills score. No significant weight status-related differences in child care-based physical activity were observed. No gender-related differences were found in the overall motor skills score, but boys performed better than girls in 2 of the 5 motor skills (p ≤ 0.04). Total physical activity as well as time spent in moderate-vigorous and in vigorous activity during child care were 12-25% higher and sedentary activity 5% lower in boys compared to girls (all p children, child care-based physical activity was higher in boys compared to girls. These results are important to consider when establishing physical activity recommendations or targeting health promotion interventions in young children.

    Medicinal plants have been used world-wide for thousands of years and are widely recognized as having high healing but minor toxic side effects. The scarcity and increasing demand for medicinal plants and their products have promoted the development of artificial cultivation of medicinal plants. Currently, one of the prominent issues in medicinal cultivation systems is the unstable quality of the products. Arbuscular mycorrhiza (AM) affects secondary metabolism and the production of active ingredients of medicinal plants and thus influence the quality of herbal medicines. In this review, we have assembled, analyzed, and summarized the effects of AM symbioses on secondary metabolites of medicinal plants. We conclude that symbiosis of AM is conducive to favorable characteristics of medicinal plants, by improving the production and accumulation of important active ingredients of medicinal plants such as terpenes, phenols, and alkaloids, optimizing the composition of different active ingredients in medicinal plants and ultimately improving the quality of herbal materials. We are convinced that the AM symbiosis will benefit the cultivation of medicinal plants and improve the total yield and quality of herbal materials. Through this review, we hope to draw attention to the status and prospects of, and arouse more interest in, the research field of medicinal plants and mycorrhiza.

    Cultural practices can affect the quality of pineapple fruits and its variation. The objectives of this study were to investigate (a) effects of weight class and type of planting material on fruit quality, heterogeneity in quality and proportion and yield of fruits meeting European export standards, and (b) the improvement in quality, proportion and yield of fruits meeting export standards when flowering was induced at optimum time. Experiments were conducted in Benin with cvs Sugarloaf (a Perola type) and Smooth Cayenne. In cv. Sugarloaf, experimental factors were weight class of planting material (light, mixed, heavy) and time of flowering induction (farmers', optimum) (Experiment 1). In cv. Smooth Cayenne an additional experimental factor was the type of planting material (hapas, ground suckers, a mixture of the two) (Experiment 2). Fruits from heavy planting material had higher infructescence and fruit weights, longer infructescences, shorter crowns, and smaller crown: infructescence length than fruits from light planting material. The type of planting material in Experiment 2 did not significantly affect fruit quality except crown length: fruits from hapas had shorter crowns than those from ground suckers. Crops from heavy planting material had a higher proportion and yield of fruits meeting export standards than those from other weight classes in Experiment 1 only; also the type of planting material in Experiment 2 did not affect these variates. Heterogeneity in fruit quality was usually not reduced by selecting only light or heavy planting material instead of mixing weights; incidentally the coefficient of variation was significantly reduced in fruits from heavy slips only. Heterogeneity was also not reduced by not mixing hapas and ground suckers. Flowering induction at optimum time increased the proportion and yield of fruits meeting export standards in fruits from light and mixed slip weights and in those from the mixture of heavy hapas plus ground suckers.

    OBJECTIVE: The aim of this study was to examine the influence of weight-bearing (WB) status after hip fracture surgery on 1-yr functional outcome. DESIGN: This was a prospective cohort study, carried out in a public acute hospital trauma service. The 194 patients (36 men and 158 women), with a mean...... (SD) age of 81.4 (6.1) yrs, were admitted with a hip fracture within 2009 and were followed for 1 yr thereafter. The influence of postoperative WB status on the 1-yr functional outcome was assessed using the Functional Independence Measure (18-126 points), adjusting for other known factors by multiple...... linear regression. RESULTS: Seventy-five patients (39%) were not allowed WB for a period of 2-4 wks after surgery. Improved functional outcomes were associated positively with prefracture functional level and having a trochanteric fracture during the first year after fracture (P ≤ 0.01). Non-WB status...

  16. Special-Status Plant Species Surveys and Vegetation Mapping at Lawrence Livermore National Laboratory

    Preston, R E

    2006-10-03

    This report presents the results of Jones & Stokes special-status plant surveys and vegetation mapping for the University of California, Lawrence Livermore National Laboratory (LLNL). Special-status plant surveys were conducted at Site 300 in April to May 1997 and in March to April 2002. Eight special-status plants were identified at Site 300: large-flowered fiddleneck, big tarplant, diamond-petaled poppy, round-leaved filaree, gypsum-loving larkspur, California androsace, stinkbells, and hogwallow starfish. Maps identifying the locations of these species, a discussion of the occurrence of these species at Site 300, and a checklist of the flora of Site 300 are presented. A reconnaissance survey of the LLNL Livermore Site was conducted in June 2002. This survey concluded that no special-status plants occur at the Livermore Site. Vegetation mapping was conducted in 2001 at Site 300 to update a previous vegetation study done in 1986. The purpose of the vegetation mapping was to update and to delineate more precisely the boundaries between vegetation types and to map vegetation types that previously were not mapped. The vegetation map is presented with a discussion of the vegetation classification used.

    Full Text Available In a case control study the effects of literacy, socio-economic status and the fertility behavior of mothers were fully investigated in two groups. Out of 13123 babies born in 17 hospitals during almost 8 months in 1988-1989 in Tehran 730 had a low birth weight (less than 2500 gr. As a control group, 1460 births were randomly selected from normal weight births. Some basic findings are as follows: 1Mothers who become pregnant in either age group of “less than 20” or “35 and over” will eventually have a higher chance of delivering a low birth weight baby, and as a result, such babies will gave a higher probability mortality in the first week and first month of their lives. 2 Age at marriage is positively correlated with the level of education. 3 The number of children born alive is negatively correlated with the level of education of mothers. 4 The socio-economic status of the family has a significant impact upon child spacing, and that will affect the probability of having a low birth weight newborn, and finally, will increase the mortality rate of babies.

    Mobility disability (MD) and obesity are conditions which have been associated with weaker labour market attachment. This study investigates whether the combined burden of MD and obesity increase the risk of disability pension compared with having only one of these conditions (the reference group). A nationwide cohort study, based on national surveys made between 1996 and 2011, was conducted including 50,015 individuals aged 19-64 years who were followed-up in a large database in terms of attainment of disability pension until 31 December 2012 (at the latest). Proportional hazards regression models were used to analyse the risk of all-cause and diagnosis-specific disability pension with six exposure groups, established by mobility and weight status (BMI) obtained through self-reports. A total of 2296 participants had received disability pension after a mean follow-up period of 7.2 years (SD 4.6). People with MD, regardless of weight, had 4-8 times higher risk of disability pension (for any reason) compared with the reference group (individuals with normal weight and no MD). No evidence of a double burden of MD and obesity with disability pension was observed in this study. MD seemed to contribute more to the risk of disability pension than weight status. In a long-term perspective, society and also people at risk of these disabling conditions would benefit from reallocation of resources from disability pensions to health-promoting and preventive policies, not least targeting MD.

    The history of the Red List of Japanese vascular plants is briefly reviewed for editing and research. Especially on the results of recent monitoring, the present status of information and conservation activities on the endangered plants in Japan is discussed and the dynamics of the Japanese flora are taken up, in relation to basic research on plant biodiversity on the Japanese Archipelago. The figures of endangered plants are not very variable during the past quarter of a century, but we can surmise that the conservation of threatened species in Japan has been promoted to some extent. Based on the results of such a study, proposals are made to contribute to the sustainable use of plant biodiversity on the Japanese Archipelago under a global conspectus.

    Nitrogen plays a key role in crop yields. Hence, farmers may apply excessive N fertilizers to crop fields, inducing environmental pollution. Crop N monitoring methods have been developed to improve N fertilizer management, most of them based on leaf or canopy optical-property measurements. However, sensitivity to environmental interference remains an important drawback. Electrical impedance has been applied to determine the physiological and nutritional status of plant tissue, but no studies related to plant-N contents are reported. The objective of this article is to analyze how the electrical impedance response of plants is affected by their N status. Four sets of lettuce (Lactuca sativa L.) with a different N-source concentrations per set were used. Total nitrogen and electrical impedance spectra (in a 1 to 100 kHz frequency range) were measured five times per set, three times every other day. Minimum phase angles of impedance spectra were detected and analyzed, together with the frequency value in which they occurred, and their magnitude at that frequency. High and positive correlation was observed between plant N content and frequency values at minimum phase angle with no significant variations detected between days of measurement. These results suggest that electrical impedance can be sensitive to plant N status.

    A novel approach to support the inspection of greenhouse crops is based on the measurement of volatile organic compounds emitted by unhealthy plants. This approach has attracted some serious interest over the last decade. In pursuit of this interest, we performed several experiments at the laboratory-scale to pinpoint marker volatiles that can be used to indicate certain health problems. In addition to these laboratory experiments, pilot and model studies were performed in order to verify the validity of these marker volatiles under real-world conditions. This paper provides an overview of results and gives an outlook on the use of plant volatiles for plant health monitoring.

    Full Text Available Abstract Background Over the last decades, a decline in motor skills and in physical activity and an increase in obesity has been observed in children. However, there is a lack of data in young children. We tested if differences in motor skills and in physical activity according to weight or gender were already present in 2- to 4-year-old children. Methods Fifty-eight child care centers in the French part of Switzerland were randomly selected for the Youp'là bouge study. Motor skills were assessed by an obstacle course including 5 motor skills, derived from the Zurich Neuromotor Assessment test. Physical activity was measured with accelerometers (GT1M, Actigraph, Florida, USA using age-adapted cut-offs. Weight status was assessed using the International Obesity Task Force criteria (healthy weight vs overweight for body mass index (BMI. Results Of the 529 children (49% girls, 3.4 ± 0.6 years, BMI 16.2 ± 1.2 kg/m2, 13% were overweight. There were no significant weight status-related differences in the single skills of the obstacle course, but there was a trend (p = 0.059 for a lower performance of overweight children in the overall motor skills score. No significant weight status-related differences in child care-based physical activity were observed. No gender-related differences were found in the overall motor skills score, but boys performed better than girls in 2 of the 5 motor skills (p ≤ 0.04. Total physical activity as well as time spent in moderate-vigorous and in vigorous activity during child care were 12-25% higher and sedentary activity 5% lower in boys compared to girls (all p Conclusions At this early age, there were no significant weight status- or gender-related differences in global motor skills. However, in accordance to data in older children, child care-based physical activity was higher in boys compared to girls. These results are important to consider when establishing physical activity recommendations or targeting

    To analyze the influence of maternal nutritional status, weight gain and energy consumption on fetal growth in high-risk pregnancies. A prospective study from August 2009 to August 2010 with the following inclusion criteria: puerperae up to the 5th postpartum day; high-risk singleton pregnancies (characterized by medical or obstetrical complications during pregnancy); live fetus at labor onset; delivery at the institution; maternal weight measured on the day of delivery, and presence of medical and/or obstetrical complications characterizing pregnancy as high-risk. Nutritional status was assessed by pregestational body mass index and body mass index in late pregnancy, and the patients were classified as: underweight, adequate, overweight and obese. A food frequency questionnaire was applied to evaluate energy consumption. We investigated maternal weight gain, delivery data and perinatal outcomes, as well as fetal growth based on the occurrence of small for gestational age and large for gestational age neonates. We included 374 women who were divided into three study groups according to newborn birth weight: adequate for gestational age (270 cases, 72.2%), small for gestational age (91 cases, 24.3%), and large for gestational age (13 cases, 3.5%). Univaried analysis showed that women with small for gestational age neonates had a significantly lower mean pregestational body mass index (23.5 kg/m², ppregnancy (27.7 kg/m², ppregnancy (25.3%, ppregnancy (34.3 kg/m², ppregnancy (53.8%, ppregnancy (OR=0.9; CI95% 0.8-0.9, ppregnancy (OR=3.6; 95%CI 1.1-11.7, p=0.04). The maternal nutritional status at the end of pregnancy in high-risk pregnancies is independently associated with fetal growth, the body mass index during late pregnancy is a protective factor against small for gestational age neonates, and maternal obesity is a risk factor for large for gestational age neonates.

  12. Increases in body weight and nutritional status of transplanted Alaskan caribou

    2000-04-01

    Full Text Available Body weight and natality rate in ungulates can be useful indices to nutririon, bur they may also be influenced by genetic and climatic factors. Because caribou {Rangifer tarandus granti are distributed as discrete populations of metapopulations (i.e., herds that are usually reproductively isolated from each other for unknown periods, it is difficult to separate the influence of genetics and nutrition on body weight, especially where historical data are lacking. To help elucidate the influence of nutrition on potential variation in body weight and natality of caribou in Alaska, we reviewed data for body weight and natality in 5 populations which resulted from Transplants to previously ungrazed ranges, or to areas where reindeer and caribou had been absent for many decades. In 2 of 5 populations body weight increased significantly, and likely increased in the other 3 populations, but data were insufficient. Natality rate increased in all 5 populations, proportion of fecund yearlings was high and 3 of the 5 newly established herds increased at about the maximum biological potential for the species (lambda=1.35. In the Adak transplant, a lactating yearling was documented. These 5 transplanted populations provide additional evidence that body weight and natality rate in Alaskan caribou are sensitive to changes in population density and relatively short-term (i.e., 10 years increases in grazing pressure independenr of climate and genetics.

    Bacterial artificial chromosome (BAC) libraries are extremely valuable large-insert DNA libraries for physical mapping, positional cloning, comparative genomic analysis, complete genome sequencing, and evolutionary studies. Due to their stability and relative simplicity BAC libraries are most preferred over other approaches for cloning large genomic DNA fragments for large-insert libraries. Isolation of intact high molecular weight (HMW) DNA is a critical step underlying the success of large-insert genomic DNA library construction. It requires the isolation of purified nuclei, embedding them into LMP agarose plugs, restriction digestion of the plugs, and quite often size selection using PFGE and electro-elution of insert DNA. The construction of BAC libraries is complex and challenging for most molecular laboratories. To facilitate the construction of BAC libraries, we present a step-by-step protocol for isolation of HMW DNA and construction of plant BAC libraries.

    Secondary copper smelters, which primarily utilize the waste materials that contain organic impurities, and the zinc recovery plant, which handles mostly fly ash and slag from the iron and steel industry, are major emission sources of polychlorinated dibenzo-p-dioxins and polychlorinated dibenzofurans (PCDD/Fs) in Taiwan. In this study, we compared the levels of erythrocyte glutathione (GSH), erythrocyte superoxide dismutase (SOD) and plasma malondialdehyde (MDA) in workers at a secondary copper smelting plant and a zinc recovery plant who may have been exposed to PCDD/Fs. Though the PCDD/F levels were higher in workers of zinc recovery plant than those of secondary copper smelting plant, no significant difference was found for serum PCDD/F levels between the two kinds of plants. We observed a significant difference in plasma MDA levels between workers at the zinc recovery plant (2.54 microM) and those at the copper smelting plant (1.79 microM). There was and a significant positive correlation between plasma MDA levels and the PCDD/Fs levels. In addition, we observed that the MDA levels were not affected by smoking and exercise status. Therefore, the data suggest that the MDA levels of the metal recovery workers are influenced by their PCDD/F exposure. The erythrocyte SOD activity in workers from the zinc recovery plant was marginally higher than that from the secondary copper plant (196 vs. 146 units/ml, pworkers of the zinc recovery plant than in workers of the secondary copper smelting plant in Taiwan.

  15. Function of Succinoglycan Polysaccharide in Sinorhizobium meliloti Host Plant Invasion Depends on Succinylation, Not Molecular Weight

    Directory of Open Access Journals (Sweden)

    Hajeewaka C. Mendis

    2016-06-01

    Full Text Available The acidic polysaccharide succinoglycan produced by the rhizobial symbiont Sinorhizobium meliloti 1021 is required for this bacterium to invade the host plant Medicago truncatula and establish a nitrogen-fixing symbiosis. S. meliloti mutants that cannot make succinoglycan cannot initiate invasion structures called infection threads in plant root hairs. S. meliloti exoH mutants that cannot succinylate succinoglycan are also unable to form infection threads, despite the fact that they make large quantities of succinoglycan. Succinoglycan produced by exoH mutants is refractory to cleavage by the glycanases encoded by exoK and exsH, and thus succinoglycan produced by exoH mutants is made only in the high-molecular-weight (HMW form. One interpretation of the symbiotic defect of exoH mutants is that the low-molecular-weight (LMW form of succinoglycan is required for infection thread formation. However, our data demonstrate that production of the HMW form of succinoglycan by S. meliloti 1021 is sufficient for invasion of the host M. truncatula and that the LMW form is not required. Here, we show that S. meliloti strains deficient in the exoK- and exsH-encoded glycanases invade M. truncatula and form a productive symbiosis, although they do this with somewhat less efficiency than the wild type. We have also characterized the polysaccharides produced by these double glycanase mutants and determined that they consist of only HMW succinoglycan and no detectable LMW succinoglycan. This demonstrates that LMW succinoglycan is not required for host invasion. These results suggest succinoglycan function is not dependent upon the presence of a small, readily diffusible form.

    Peroxiredoxins are ubiquitous thioredoxin-dependent peroxidases presumed to display, upon environmental constraints, a chaperone function resulting from a redox-dependent conformational switch. In this work, using biochemical and genetic approaches, we aimed to unravel the factors regulating the redox status and the conformation of the plastidial 2-Cys peroxiredoxin (2-Cys PRX) in plants. In Arabidopsis, we show that in optimal growth conditions, the overoxidation level mainly depends on the availability of thioredoxin-related electron donors, but not on sulfiredoxin, the enzyme reducing the 2-Cys PRX overoxidized form. We also observed that upon various physiological temperature, osmotic and light stress conditions, the overoxidation level and oligomerization status of 2-Cys PRX can moderately vary depending on the constraint type. Further, no major change was noticed regarding protein conformation in water-stressed Arabidopsis, barley and potato plants, whereas species-dependent up- and down-variations in overoxidation were observed. In contrast, both 2-Cys PRX overoxidation and oligomerization were strongly induced during a severe oxidative stress generated by methyl viologen. From these data, revealing that the oligomerization status of plant 2-Cys PRX does not exhibit important variation and is not tightly linked to the protein redox status upon physiologically relevant environmental constraints, the possible in planta functions of 2-Cys PRX are discussed.

    Pregestational weight status and maternal smoking during pregnancy are significantly associated with fetal and childhood growth. However, few studies have examined associations between childhood growth and combinations of these factors using multilevel analysis. This study aimed to describe differences in childhood growth trajectories according to these combinations, using data from a prospective cohort study in Japan. The study participants were 1,973 women and their singletons, who were born between April 1, 1991 and March 31, 2003. Children were categorized according to whether they were born to normal-weight, nonsmoking mothers (NN); normal-weight, smoking mothers (NS); underweight, nonsmoking mothers (UN); underweight, smoking mothers (US); overweight, nonsmoking mothers (ON); or overweight, smoking mothers (OS). Birth weight and anthropometric data were collected from 1,965 children at birth (99.6%), 1,655 aged 3 (83.9%), 1,527 aged 5 (77.4%), 1,497 aged 7-8 (75.9%), and 1,501 aged 9-10 (76.1%). Multilevel analysis examining both individual and age as different level variables according to sex was used to describe the trajectories of body mass index z scores for statistical analyses. Although children of the OS group were the leanest at birth, their body mass indices had increased rapidly by 3 years of age. Moreover, body mass index was also likely to increase in boys in the NS and ON groups. A different trend was observed in girls. Body mass index decreased from 5 years of age in girls in the US group. There were no remarkable differences in body mass index trajectories between children in the other groups. In conclusion, childhood growth trajectories differed according to combinations of pregestational weight status and maternal smoking during pregnancy. Further, there were sex-related differences in the associations between childhood growth and factor combinations.

    Full Text Available Abstract Background Child growth is internationally recognized as an important indicator of nutritional status and health in populations. This study was aimed to compare age- and gender-specific height, weight and BMI percentiles and nutritional status relative to the international growth references among Pakistani school-aged children. Methods A population-based study was conducted with a multistage cluster sample of 1860 children aged five to twelve years in Lahore, Pakistan. Smoothed height, weight and BMI percentile curves were obtained and comparison was made with the World Health Organization 2007 (WHO and United States' Centers for Disease Control and Prevention 2000 (USCDC references. Over- and under-nutrition were defined according to the WHO and USCDC references, and the International Obesity Task Force (IOTF cut-offs. Simple descriptive statistics were used and statistical significance was considered at P Results Height, weight and BMI percentiles increased with age among both boys and girls, and both had approximately the same height and a lower weight and BMI as compared to the WHO and USCDC references. Mean differences from zero for height-, weight- and BMI-for-age z score values relative to the WHO and USCDC references were significant (P Conclusion Pakistani school-aged children significantly differed from the WHO and USCDC references. However, z score means relative to the WHO reference were closer to zero and the present study as compared to the USCDC reference. Overweight and obesity were significantly higher while underweight and thinness/wasting were significantly lower relative to the WHO reference as compared to the USCDC reference and the IOTF cut-offs. New growth charts for Pakistani children based on a nationally representative sample should be developed. Nevertheless, shifting to use of the 2007 WHO child growth reference might have important implications for child health programs and primary care pediatric clinics.

We assessed the effects of polymer hydrogel amendment on the water holding capacity of a green roof substrate, as well as on water status and growth of Salvia officinalis. Plants were grown in green roof experimental modules containing 8 cm or 12 cm deep substrate (control) or substrate mixed with hydrogel at two different concentrations: 0.3 or 0.6%. Hydrogel significantly increased the substrate's water content at saturation, as well as water available to vegetation. Plants grown in 8 cm deep substrate mixed with 0.6% of hydrogel showed the best performance in terms of water status and membrane integrity under drought stress, associated to the lowest above-ground biomass. Our results provide experimental evidence that polymer hydrogel amendments enhance water supply to vegetation at the establishment phase of a green roof. In particular, the water status of plants is most effectively improved when reduced substrate depths are used to limit the biomass accumulation during early growth stages. A significant loss of water holding capacity of substrate-hydrogel blends was observed after 5 months from establishment of the experimental modules. We suggest that cross-optimization of physical-chemical characteristics of hydrogels and green roof substrates is needed to improve long term effectiveness of polymer-hydrogel blends.

    Environmental changes have facilitated the rapid increase in childhood obesity. One such change is increased presence of food marketing which promotes intake of high-fat, energy-dense foods. This study tested the hypotheses that overweight (OW) children are more sensitive to the intake-enhancing effects of food branding than non-OW children, and that the relationship between weight status and intake of branded foods is mediated by level of food brand awareness. Forty-three non-OW (n = 23) and OW (n = 20) children from diverse ethnic backgrounds participated in four dinnertime visits to test their intake of meals where food brands were present ("branded") or absent ("unbranded"). Food brand awareness was assessed by testing children's abilities to match food brand logos with correct foods and name specific brands from recall. Weight and height were measured on the first visit to determine BMI z-score and weight status. OW children consumed significantly more energy per meal than non-OW. Child age and brand awareness were positively associated. OW children consumed an additional 40 kcal in branded vs. unbranded meals whereas non-OW children consumed 45 kcal less in branded meals. Overweight children showed greater responsiveness to food branding, and they may be at risk in environments that are highly inundated with messages about food.

    To explore the relationship between essential fatty acids (FA) and weight changes in adolescent girls with eating disorders (ED). Blood samples were obtained from 220 girls with ED and 39 healthy controls. The girls with ED were 15.3 ± 1.5 years of age and weighed 49.8 ± 8.7 kg (BMI 18.3 ± 2.8 kg/m(2)) after a weight loss of 6.8 ± 6.4 kg. FA were analysed in plasma phospholipids (PPL) and erythrocyte membranes (ERY). The proportions of saturated and monounsaturated FA were increased during weight loss, while linoleic acid (18:2ω6) was decreased. The proportions of eicosapentanoic acid (EPA) (20:5ω3) and docosahexanoic acid (DHA) (22:6ω3) in PPL and ERY did not differ from controls. The activity of stearoyl-CoA-desaturase was increased as evidenced by an increased product/precursor ratio and correlated with the rate of weight loss. The activities of delta-6-desaturase and delta-5-desaturase did not differ from controls. The rate of weight loss was inversely correlated with delta-6-desaturase and directly correlated with delta-5-desaturase. The FA profile indicates low-fat intake, fat mobilization from stores and an increased conversion of essential FA at the delta-5-desaturase step during weight loss in adolescent girls with ED. Normal levels of EPA and DHA were maintained. © 2011 The Author(s)/Acta Paediatrica © 2011 Foundation Acta Paediatrica.

    Root exudate composition and quantity vary in relation to plant nutritional status, but the impact of the differences on rhizosphere microbial communities is not known. To examine this question, we performed an experiment with barley (Hordeum vulgare) plants under iron-limiting and iron-sufficient growth conditions. Plants were grown in an iron-limiting soil in root box microcosms. One-half of the plants were treated with foliar iron every day to inhibit phytosiderophore production and to alter root exudate composition. After 30 days, the bacterial communities associated with different root zones, including the primary root tips, nonelongating secondary root tips, sites of lateral root emergence, and older roots distal from the tip, were characterized by using 16S ribosomal DNA (rDNA) fingerprints generated by PCR-denaturing gradient gel electrophoresis (DGGE). Our results showed that the microbial communities associated with the different root locations produced many common 16S rDNA bands but that the communities could be distinguished by using correspondence analysis. Approximately 40% of the variation between communities could be attributed to plant iron nutritional status. A sequence analysis of clones generated from a single 16S rDNA band obtained at all of the root locations revealed that there were taxonomically different species in the same band, suggesting that the resolving power of DGGE for characterization of community structure at the species level is limited. Our results suggest that the bacterial communities in the rhizosphere are substantially different in different root zones and that a rhizosphere community may be altered by changes in root exudate composition caused by changes in plant iron nutritional status.

    Fast-food restaurants (FFR) are prevalent. Binge eating is common among overweight and obese women. For women prone to binge eating, neighbourhood FFR availability (i.e. the neighbourhood around one's home) may promote poor diet and overweight/obesity. The present study tested the effects of binge eating and neighbourhood FFR availability on diet (fat and total energy intake) and BMI among African American and Hispanic/Latino women. All measures represent baseline data from the Health is Power randomized clinical trial. The numbers of FFR in participants' neighbourhoods were counted and dichotomized (0 or ≥1 neighbourhood FFR). Participants completed measures of binge eating status and diet. Weight and height were measured and BMI calculated. 2 (binge eating status) × 2 (neighbourhood FFR availability) ANCOVA tested effects on diet and BMI while controlling for demographics. Houston and Austin, TX, USA. African American and Hispanic/Latino women aged 25-60 years. Of the total sample (n 162), 48 % had 1-15 neighbourhood FFR and 29 % were binge eaters. There was an interaction effect on BMI (P = 0·05). Binge eaters with ≥1 neighbourhood FFR had higher BMI than non-binge eaters or binge eaters with no neighbourhood FFR. There were no significant interactions or neighbourhood FFR main effects on total energy or fat intake (P > 0·05). A main effect of binge eating showed that binge eaters consumed more total energy (P = 0·005) and fat (P = 0·005) than non-binge eaters. Binge eaters represented a substantial proportion of this predominantly overweight and obese sample of African American and Hispanic/Latino women. The association between neighbourhood FFR availability and weight status is complicated by binge eating status, which is related to diet.

    Physical fitness performance is an important health correlate yet is often unrelated to sedentary behaviour in early adolescence. In this study, we examined the association of sedentary behaviour (i.e. screen time) with weight-related health markers and blood pressure, after controlling for cardiorespiratory fitness performance. American middle school students (N = 153, 56% females) aged 11-15 years (mean 12.6 years, s = 0.5) completed assessments of cardiorespiratory fitness performance, screen time, weight status (BMI percentile, waist-to-height ratio), and blood pressure. Multivariate analysis of covariance, controlling for cardiorespiratory fitness performance, found those who met the daily recommendation of 2 h or less of screen time (n = 36, 23.5%) had significantly lower BMI (p fitness and sedentary behaviours to maximize early adolescent health because these behaviours are likely to have unique and independent effects on youth health markers.

    women who have experienced miscarriage may be at increased risk for elevated depressive and anxiety symptoms in subsequent pregnancies. Exercise may be a useful strategy for coping with these symptoms. Little is known about how miscarriage influences prenatal exercise behavior. The study purpose was to examine the influences of miscarriage history and prepregnancy weight status on pregnant women's psychological health, exercise motivation, and behavior using the Theory of Planned Behavior. Pregnant women (N=203; 41 with prior miscarriage; 72 overweight/obese; BMI > 25.0) in the northeast United States. Women prospectively reported their depressive/anxiety symptoms and exercise motivation/behavior in the 1st, 2nd, and 3rd trimesters via mailed surveys. Group differences in depressive/anxiety symptoms, exercise behavior, and its motivational determinants were examined using Chi Square analyses and Univariate and Multivariate Analyses of Covariance. Women with a history of miscarriage had higher 1st and 2nd trimester depressive/anxiety symptoms and lower 1st trimester attitudes about exercise and 1st and 2nd trimester perceived behavior control than women without a history of miscarriage. Overweight/obese women had higher 1st and 2nd trimester pregnancy depressive/anxiety symptoms, engaged in less prepregnancy exercise, and had lower levels of exercise intention, attitude, and perceived behavior control throughout pregnancy than normal weight women. Women with a history of miscarriage and overweight/obese women have poorer psychological health and lower motivation to exercise during pregnancy than women without a history of miscarriage and normal weight women. Interventions and healthcare provider communications aimed at promoting perinatal exercise behavior and psychological health should take into account pre-pregnancy weight status and pregnancy history to identify strategies to help women, particularly overweight/obese women with a history of miscarriage, to

    To explore associations between overweight status and the frequency of family dinners (FFD) for adolescents and how those associations differ across race and ethnicity. A sample of 5014 respondents between 12 and 15 years of age from the 1997 wave of the National Longitudinal Survey of Youth 1997 (NLSY97) was used. BMI was calculated using self-reported height and weight; 13.3% of respondents qualified as overweight, 16.4% qualified as at-risk-of-overweight, and 1.9% qualified as underweight. The remainder were normal weight. FFD was defined as the number of times respondents had dinner with their families in a typical week in the past year. Multinomial logistic regression models were estimated separately for non-Hispanic whites vs. blacks and Hispanics for odds of belonging to the other weight categories compared with normal weight. A supplementary longitudinal analysis estimated the odds of change in overweight status between 1997 and 2000. In 1997, the FFD distribution was as follows: 0, 8.3%; 1 or 2, 7.3%; 3 or 4, 13.4%; 5 or 6, 28.1%; 7, 42%. For whites, higher FFD was associated with reduced odds of being overweight in 1997, reduced odds of becoming overweight, and increased odds of ceasing to be overweight by 2000. No such associations were found for blacks and Hispanics. Reasons for racial and ethnic differences in the relationship between FFD and overweight may include differences in the types and portions of food consumed at family meals. More research is needed to verify this.

    Full Text Available Although prior studies have suggested that overweight and obesity in childhood are associated with poorer functional movement performance, no study appears to have examined this issue in a pediatric population. The relations between BMI, ambulatory physical activity and functional movement screen (FMS performance were compared in 58, 10-11-year-old children. Total FMS score was significantly, negatively correlated with BMI (=.0001 and positively related to PA (=.029. Normal weight children scored significantly better for total FMS score compared to children classified as overweight/obese (=.0001. Mean ± S.D. of FMS scores were 15.5±2.2 and 10.6±2.1 in normal weight and overweight/obese children, respectively. BMI and PA were also significant predictors of functional movement (=.0001, Adjusted 2=.602 with BMI and PA predicting 52.9% and 7.3% of the variance in total FMS score, respectively. The results of this study highlight that ambulatory physical activity and weight status are significant predictors of functional movement in British children. Scientists and practitioners therefore need to consider interventions which develop functional movement skills alongside physical activity and weight management strategies in children in order to reduce the risks of orthopaedic abnormality arising from suboptimal movement patterns in later life.

    Body satisfaction is important for the prevention of disordered eating and body image disturbances. Yet, little is known about body esteem and what influences it among younger children. The purpose of this study was to evaluate body esteem and the relationships between body esteem, weight, gender, and physical activity in elementary school children. A total of 214 third graders in a U.S. Midwestern state participated in this correlational study. The Body Mass Index-for-age, the Body Esteem Scale (BES), BE-Weight, BE-Appearance, and a Physical Activity Checklist were used to examine the relationships between the variables using bivariate correlations and analysis of variance. While children's body esteem did not differ by physical activity, important interactions were identified between weight status and gender in global body esteem and BE-Appearance. It is critical to examine attitudes about weight and appearance and the relationship between body esteem and self-esteem further among middle childhood-aged children.

    Mining sites shelter a characteristic biodiversity with large potential for the phytoremediation of metal contaminated soils. Endophytic plant growth-promoting bacteria were isolated from two metal-(hyper)accumulator plant species growing in a metal contaminated mine soil. After characterizing their plant growth-promoting traits, consortia of putative endophytes were used to carry out an endophyte-assisted phytoextraction experiment using Noccaea caerulescens and Rumex acetosa (singly and in combination) under controlled conditions. We evaluated the influence of endophyte-inoculated plants on soil physicochemical and microbial properties, as well as plant physiological parameters and metal concentrations. Data interpretation through the grouping of soil properties within a set of ecosystem services was also carried out. When grown together, we observed a 41 and 16% increase in the growth of N. caerulescens and R. acetosa plants, respectively, as well as higher values of Zn phytoextraction and soil microbial biomass and functional diversity. Inoculation of the consortia of putative endophytes did not lead to higher values of plant metal uptake, but it improved the plants' physiological status, by increasing the content of chlorophylls and carotenoids by up to 28 and 36%, respectively, indicating a reduction in the stress level of plants. Endophyte-inoculation also stimulated soil microbial communities: higher values of acid phosphatase activity (related to the phosphate solubilising traits of the endophytes), bacterial and fungal abundance, and structural diversity. The positive effects of plant growth and endophyte inoculation on soil properties were reflected in an enhancement of some ecosystem services (biodiversity, nutrient cycling, water flow regulation, water purification and contamination control).

    To investigate the nutritional status of North African (NA) immigrant women in Italy, analysing their body size, adiposity and body image perception in comparison to Italian natives and NA residents. The study utilized a cross-sectional design. Anthropometric traits were directly measured and a few indices were computed as proxy measures of nutritional status and adiposity. Body image perception was assessed using silhouette drawings. ANCOVA, adjusted for age, was used to compare anthropometric traits among different groups of women and the χ 2 test to analyse differences in the prevalence of nutritional status. Italy and North Africa (Tunisia, Morocco). A sample of 433 women aged 18-60 years old: NA immigrants (n 105); Italians (n 100); Tunisians (n 104); Moroccans (n 124). Overweight/obesity prevalence was very high in immigrants (79·8 %). Immigrants had the highest BMI value, the greatest hip circumference and mid upper-arm circumference. Their triceps skinfold thickness was significantly higher than that of Italians, but lower than that of NA residents. NA immigrant women in Italy showed a higher incidence of overweight compared with Italians and NA residents. All groups showed a preference for a thinner body in comparison to their actual bodies and the immigrants are the most dissatisfied. Immigrants remain a high-risk group for obesity. Assessment of their body composition and health risk profile should be improved by using specific anthropometric measures that are easy to collect even in the case of large migration flows.

    Tomato seedlings were grown under seven kinds of fluorescent lamps, including two that are commercially available, and five experimental lamps. Detailed descriptions and spectral emission curves for these lamps are presented.The 78/22 lamp, which emitted most of its energy above 500 mμ, more than ten percent above 700 mμ, and had a sharp peak output at 660 mμ, generally produced superior fresh and dry weight yields. This effect may be due primarily to the high peak of energy emitted at approximately 660 mμ, combined with a considerable emission in the far-red, which in turn may be related to the red ↔ far-red reversibility phenomeon.The Com I lamp, which lacked the sharp peak output at 660 mμ and emitted more energy in the blue than the 78/22 lamp, was generally second only to the latter in promoting plant growth. A high moisture content was found in plants under this lamp in some experiments.The IRIII lamp had the sharp peak output at 660 mμ but greater output in the blue than the 78/22 lamp. The 282 lamp output was similar to the 78/22 but lacked the high peak. Both of these lamps generally gave improved results over those produced by commercial Gro-Lux, Warm-white, and FLAT lamps. This was attributed to the greater percentage of red and far-red energy emission by the former two lamps. The yields with the FLAT lamp were consistently lowest of all. This has been attributed to the high percentage of emitted energy in the blue and green portions of the spectrum.Both length of the test period (13 days versus 26 days) and light intensity (550 μw/cm(2) versus 1100 μw/cm(2)) may be important factors in determining which composition of spectral energy emission produces the greatest yields. Under low intensity and short test period the Com I light produced highest fresh- and dry-weight yields, but under high intensity and longer growth period the 78/22 lamp gave greatest yields. This effect may be due to inhibition of leaf expansion by red light in the early

    To investigate associations between eating frequency and energy intake, energy density, diet quality and body weight status in adults from the USA, combined data from the 2009-2010 and 2011-2012 National Health and Nutrition Examination Survey (NHANES) were used in this study. The first 24-h dietary recall data from eligible participants (4017 men and 3774 women) were used to calculate eating frequency, as well as energy intake, energy density and the Healthy Eating Index 2010 (HEI-2010), as a measure of diet quality. BMI and waist circumference were obtained from the NHANES body measures data. Adjusting for confounding socio-demographic characteristics and lifestyle factors, a higher eating frequency was significantly associated with higher energy intake in both men and women (both Penergy density in both men and women, regardless of whether beverage or water intake was included in the calculation of energy density (all Pwell as waist circumference in both men (P=0·032) and women (P=0·010).

    Background Length of residence in the United States (US), changes in dietary and physical activity behaviors, and economic and social barriers contribute to high childhood obesity rates among children from immigrant families in the US. Brazilians comprise a fast-growing immigrant population group in the US, yet little research has focused on health issues affecting Brazilian children in immigrant families. Understanding sociocultural and environmental influences on parents' beliefs and practices related to child feeding and weight status is essential to altering obesity trends in this group. Methods Qualitative study consisting of five focus groups with a convenience sample of 29 Brazilian immigrant mothers. Results Analyses revealed that the sociocultural and environment transitions faced by Brazilian immigrant mothers' influence their beliefs and practices related to child feeding and weight status. Additionally, acculturation emerged as a factor affecting mothers' feeding practices and their children's eating habits, with mothers preferring Brazilian food environments and that their children preferring American food environments. Mothers viewed themselves as being responsible for promoting and maintaining their children's healthy eating and feeding behaviors, but changes in their social and cultural environments due to immigration and the pressures and demands of raising a family in a new country make this difficult. Conclusions Health promotion interventions to improve healthful eating and feeding practices of Brazilian children in immigrant families must account for social and cultural changes and daily life demands due to immigration as well as potential variation in the levels of acculturation between mothers and their children.

Although most characterized species of the fungal genus Colletotrichum are destructive pathogens, we show here that C. tofieldiae (Ct) is an endemic endophyte in natural Arabidopsis thaliana populations in central Spain. Colonization by Ct initiates in roots but can also spread systemically into shoots. Ct transfers the macronutrient phosphorus to shoots, promotes plant growth, and increases fertility only under phosphorus-deficient conditions, a nutrient status that might have facilitated the transition from pathogenic to beneficial lifestyles. The host’s phosphate starvation response (PSR) system controls Ct root colonization and is needed for plant growth promotion (PGP). PGP also requires PEN2-dependent indole glucosinolate metabolism, a component of innate immune responses, indicating a functional link between innate immunity and the PSR system during beneficial interactions with Ct.

    WHO has released prescriptive child growth standards for, among others, BMI-for-age (BMI-FA), mid-upper arm circumference-for-age, and weight velocity. The ability of these indices to predict child mortality remains understudied, although growth velocity prognostic value underlies current growth monitoring programs. The study aims were first to assess, in children under 2, the independent and combined ability of these indices and of stunting to predict all-cause mortality within 3 mo, and second, the comparative abilities of weight-for-length (WFL) and BMI-FA to predict short-term (<3 mo) mortality. We used anthropometry and survival data from 2402 children aged between 0 and 24 mo in a rural area of the Democratic Republic of Congo with high malnutrition and mortality rates and limited nutritional rehabilitation. Analyses used Cox proportional hazard models and receiver operating characteristic curves. Univariate analysis and age-adjusted analysis showed predictive ability of all indices. Multivariate analysis without age adjustment showed that only very low weight velocity [HR = 3.82 (95%CI = 1.91, 7.63); P < 0.001] was independently predictive. With age adjustment, very low weight velocity [HR = 3.61 (95%CI = 1.80, 7.25); P < 0.001] was again solely retained as an independent predictor. There was no evidence for a difference in predictive ability between WFL and BMI-FA. This paper shows the value of attained BMI-FA, a marker of wasting status, and recent weight velocity, a marker of the wasting process, in predicting child death using the WHO child growth standards. WFL and BMI-FA appear equivalent as predictors.

    Optimal macronutrient distribution of weight loss diets has not been established. The distribution of energy from carbohydrate and fat has been observed to promote differential plasma lipid responses in previous weight loss studies, and insulin resistance status may interact with diet composition and affect weight loss and lipid responses. Overweight and obese women (n=245) were enrolled in a 1-year behavioral weight loss intervention and randomly assigned to 1 of 3 study groups: a lower fat (20% energy), higher carbohydrate (65% energy) diet; a lower carbohydrate (45% energy), higher fat (35% energy) diet; or a walnut-rich, higher fat (35% energy), lower carbohydrate (45% energy) diet. Blood samples and data available from 213 women at baseline and at 6 months were the focus of this analysis. Triglycerides, total cholesterol, and high- and low-density lipoprotein cholesterol were quantified and compared between and within groups. Triglycerides decreased in all study arms at 6 months (Pdiet increased high-density lipoprotein cholesterol more than either the lower fat or lower carbohydrate diet (Pdiet also reduced low-density lipoprotein cholesterol in insulin-sensitive women, whereas the lower fat diet reduced both total cholesterol and high-density lipoprotein cholesterol in insulin-sensitive women (Pdiet groups, although insulin-sensitive women lost more weight with a lower fat, higher carbohydrate diet versus a higher fat, lower carbohydrate diet. The walnut-rich, higher fat diet resulted in the most favorable changes in lipid levels. URL: http://www.clinicaltrials.gov. Unique identifier: NCT01424007. © 2016 The Authors.

    Introduction Few studies have examined concordance/discordance between caregivers to identify whether caregivers see familial and parental factors in the home environment similarly or differently and whether the agreement or disagreement is related to adolescent obesity risk. Answers to these questions are important and may inform whether family-based childhood obesity interventions need to target both parents. Objective The main objective of the study is to examine whether and how parental concordance/discordance on factors in the home environment (e.g., importance of family meals, parent feeding practices, encouraging child physical activity, limit setting on child screen time) are associated with adolescent health behaviors and weight status. Design Data from two linked population-based studies were used in cross-sectional analyses. Linear regression models examined associations between parental concordance/discordance on home environment factors and adolescents’ health behaviors and weight status. Participant/Settings Racially/ethnically and socioeconomically diverse adolescents (n=1,052; 54% girls; mean age = 14.3 years) and their parents (n=2,104; 52% female; mean age = 41.0 years) from Minneapolis and St. Paul, Minnesota participated in the study. Anthropometric assessments and surveys were completed at school by adolescents and surveys were completed at home by parents. Results Parental concordance on home environment factors was high for some factors (e.g., 68% concordance on not pressuring adolescent to eat) and low for other factors (e.g., 2% concordance on parent engaging in physically activity with child 4+ hours/week). Parental concordance on positive home environment factors (e.g., frequency of family meals) was associated with more adolescent healthful eating patterns and hours of physical activity (p < 0.05), but not consistently. When parents were discordant, adolescents had higher consumption of fast food and more unhealthy weight control

    Research has shown that adolescents who frequently share evening meals with their families experience more positive health outcomes, including diets of higher nutritional quality. However, little is known about families eating together at breakfast. This study examined sociodemographic differences in family meal frequencies in a population-based adolescent sample. In addition, this study examined associations of family breakfast meal frequency with dietary quality and weight status. Cross-sectional data from EAT 2010 (Eating and Activity in Teens) included anthropometric assessments and classroom-administered surveys completed in 2009-2010. Participants included 2,793 middle and high school students (53.2% girls, mean age=14.4 years) from Minneapolis/St Paul, MN, public schools. Usual dietary intake was self-reported on a food frequency questionnaire. Height and weight were measured. Regression models adjusted for sociodemographic characteristics, family dinner frequency, family functioning, and family cohesion were used to examine associations of family breakfast frequency with dietary quality and weight status. On average, adolescents reported having family breakfast meals 1.5 times (standard deviation=2.1) and family dinner meals 4.1 times (standard deviation=2.6) in the past week. There were racial/ethnic differences in family breakfast frequency, with the highest frequencies reported by adolescents of black, Hispanic, Native American, and mixed race/ethnicity. Family breakfast frequency was also positively associated with male sex, younger age, and living in a two-parent household. Family breakfast frequency was associated with several markers of better diet quality (such as higher intake of fruit, whole grains, and fiber) and lower risk for overweight/obesity. For example, adolescents who reported seven family breakfasts in the past week consumed an average of 0.37 additional daily fruit servings compared with adolescents who never had a family breakfast meal

    Terminal drought is a major constraint to chickpea productivity. Two component traits responsible for reduction in yield under drought stress include reduction in seeds size and root length/root density. QTL-seq approach, therefore, was used to identify candidate genomic regions for 100-seed weight (100SDW) and total dry root weight to total plant dry weight ratio (RTR) under rainfed conditions. Genomewide SNP profiling of extreme phenotypic bulks from the ICC 4958 × ICC 1882 population identified two significant genomic regions, one on CaLG01 (1.08 Mb) and another on CaLG04 (2.7 Mb) linkage groups for 100SDW. Similarly, one significant genomic region on CaLG04 (1.10 Mb) was identified for RTR. Comprehensive analysis revealed four and five putative candidate genes associated with 100SDW and RTR, respectively. Subsequently, two genes (Ca_04364 and Ca_04607) for 100SDW and one gene (Ca_04586) for RTR were validated using CAPS/dCAPS markers. Identified candidate genomic regions and genes may be useful for molecular breeding for chickpea improvement. © 2016 The Authors.

    Full Text Available Objectives The purposes of this study were to assess the prevalence of underweight, overweight, and obesity and to evaluate the nutritional habits, and related factors among the Students of Jazan University. Methods This cross-sectional study was carried out during the academic year 2014/2015 in Jazan University, Gizan, South West Saudi Arabia. A total of 436 students 19–25 y of age were examined. The questionnaires, including items on eating habits, lifestyle, and socio-demographic characteristics, were completed by the students. Data on weight, height were also collected.  The data were analyzed using descriptive statistics and chi-square test. Differences were considered statistically significant at P. value  < 0.05. Results The mean weight for males and females were 67.84 and 54.79 kg respectively, with significant differences between males and females (P. value <0.05. The mean BMI for all study participants was reported as 23.31 (kg/m², also with significant difference between the males and females groups. About 45% of the students were of normal weight; the rate of obesity and underweight among students was very high (33.6% and 21.1% respectively, and their dietary habits were unhealthy. Regularity of meals was found only among (16.5% and 20.4% males and females respectively. 83.3% of males and 95.1% of females reported eating snacks during the day. Conclusion The results of this study suggest that the prevalence of overweight and obesity were very high among the studied students. The study showed the need for health education programs on nutritional education in universities in order to increase awareness of students towards healthy eating and lifestyle.   Keywords Body mass index, Cross-sectional study, underweight, overweight, Jazan

    Nonalcoholic fatty liver disease (NAFLD) is a benign condition that can progress to more severe liver damage in a process mediated, in part, by disturbances in redox balance. Additionally, some argue that it is set to become the main cause of end-stage liver disease in the near future. Here, we investigated whether a diet-induced weight loss is able to reverse hepatic lipid accumulation and to reduce oxidative stress in liver from C57BL/6 mice fed a high-fat (HF) diet. Male C57BL/6 mice were divided into four groups: SC (standard chow, 10% energy from fat, 16 wk); HF (high fat diet, 50% energy from fat, 16 wk); SC-HF (SC 8 wk followed by HF 8 wk); and HF-SC (HF 8 wk followed by SC 8 wk). The HF diet during 8 (SC-HF) and 16 weeks (HF) downregulated mRNA levels and protein expression of Nrf2 and endogenous antioxidant enzymes (superoxide dismutase, catalase, glutathione peroxidase and glutathione reductase) in the liver, caused liver steatosis, affected liver function markers, increased intra-abdominal and subcutaneous adipose tissue, and induced glucose intolerance and hypercholesterolemia compared to controls (SC). Diet-induced weight loss significantly reduced the intrahepatic lipid accumulation, improved glucose tolerance, and restored both gene and protein expression of the antioxidant enzymes. Our findings suggest that a dietary intervention aimed to induce weight loss may exert protective effects in NAFLD as it can reduce hepatic oxidative stress and intrahepatic lipid accumulation, which can hinder the progression of this condition to more severe states.

    Both the obesity rate and pocket money are rising among children in China. This study examined family correlates of children's pocket money, associations of pocket money with eating behaviors and weight status, and how the associations may be modified by schools' unhealthy food restrictions in urban China. Data were collected in 2015 from 1648 students in 16 primary and middle schools in four mega-cities in China (4 schools/city): Beijing, Shanghai, Nanjing, and Xi'an. Cluster robust negative binomial regression models were fit to assess family correlates of pocket money, associations of pocket money with child eating behaviors and weight outcomes, and possible modifying effects of schools' unhealthy food restrictions. Sixty-nine percent of students received pocket money weekly. Students received more pocket money if mothers frequently ate out of home (IRR=2.28 [1.76, 2.94]) and/or family rarely had dinner together (IRR=1.42, 95%=[1.01, 1.99]). Students got less pocket money if parents were concerned about child's future health due to unhealthy eating (IRR=0.56 [0.32,0.98]). Students with more pocket money more frequently consumed (by 25-89%) sugary beverages, snacks, fast food, or at street food stalls, and were 45-90% more likely to be overweight/obese. Associations of pocket money with unhealthy eating and overweight/obesity were weaker in schools with unhealthy food restrictions. Pocket money is a risk factor for unhealthy eating and obesity in urban China. School policies may buffer pocket money's negative influence on students' eating and weight status. Copyright © 2017.

    The double burden of malnutrition, defined by the coexistence of undernutrition and overweight, is well documented in low- and middle-income countries. However, the mechanisms by which employment may be related to maternal and child weight status in low- and middle-income countries are not well understood. We conducted in-depth interviews among 20 mothers who participated in Project MIEL, a contemporary trial which evaluated the effects of an integrated micronutrient supplement and parenting intervention in rural Guatemala. We utilized semi-structured interviews to explore the pathways by which maternal employment might influence bodyweight. Interviews were structured to explore the factors that mothers considered when deciding whether or not to participate in the labor force and how mothers perceived the influence of employment on determinants of their own bodyweight and that of their children. Themes were used to develop a conceptual framework. Mothers described four pathways through which employment could lead to changes in weight status: changes in food purchasing; improved household well-being; changes in time allocation; and psychological effects. Mothers described purchasing increased quantities and more varied types of food, as well as the purchase of energy-dense foods. Less time to devote to food preparation resulted in mothers preparing quicker meals and relying on substitute childcare. Mothers also expressed feelings of worry and neglect in relation to being employed, and perceived that these feelings would affect weight. A better understanding of these mechanisms is important for developing policies and programs to support women in the workplace and also reducing maternal and child overweight in Guatemala. © 2017 John Wiley & Sons Ltd.

    Pastures often experience a pulse of phosphorus (P) when fertilized. We examined the role of arbuscular mycorrhizal fungi (AMF) in the uptake of P from a pulse. Five legumes (Kennedia prostrata, Cullen australasicum, Bituminaria bituminosa, Medicago sativa and Trifolium subterraneum) were grown in a moderate P, sterilized field soil, either with (+AMF) or without (-AMF) addition of unsterilized field soil. After 9-10 weeks, half the pots received 15 mg P kg(-1) of soil. One week later, we measured: shoot and root dry weights; percentage of root length colonized by AMF; plant P, nitrogen and manganese (Mn) concentrations; and rhizosphere carboxylates, pH and plant-available P. The P pulse raised root P concentration by a similar amount in uncolonized and colonized plants, but shoot P concentration increased by 143% in uncolonized plants and 53% in colonized plants. Inoculation with AMF decreased the amount of rhizosphere carboxylates by 52%, raised rhizosphere pH by ∼0.2-0.7 pH units and lowered shoot Mn concentration by 38%. We conclude that AMF are not simply a means for plants to enhance P uptake when P is limiting, but also act to maintain shoot P within narrow boundaries and can affect nutrient uptake through their influence on rhizosphere chemistry. © 2013 John Wiley & Sons Ltd.

    Full Text Available The conservation of plants has not generated the sense of urgency—or the funding—that drives the conservation of animals, although plants are far more important for us. There are an estimated 500,000 species of land plants (angiosperms, gymnosperms, ferns, lycophytes, and bryophytes, with diversity strongly concentrated in the humid tropics. Many species are still unknown to science. Perhaps a third of all land plants are at risk of extinction, including many that are undescribed, or are described but otherwise data deficient. There have been few known global extinctions so far, but many additional species have not been recorded recently and may be extinct. Although only a minority of plant species have a specific human use, many more play important roles in natural ecosystems and the services they provide, and rare species are more likely to have unusual traits that could be useful in the future. The major threats to plant diversity include habitat loss, fragmentation, and degradation, overexploitation, invasive species, pollution, and anthropogenic climate change. Conservation of plant diversity is a massive task if viewed globally, but the combination of a well-designed and well-managed protected area system and ex situ gap-filling and back-up should work anywhere. The most urgent needs are for the completion of the global botanical inventory and an assessment of the conservation status of the 94% of plant species not yet evaluated, so that both in and ex situ conservation can be targeted efficiently. Globally, the biggest conservation gap is in the hyperdiverse lowland tropics and this is where attention needs to be focused.

    A glasshouse experiment was conducted to study the effect of different type of compost and fertilizers on the growth of tomato (Lycopersicon esculentum). The experiment consisted of sixteen treatments. Compost of Empty fruit bunch (EFB) and cow dung is mixed in the ratio of 3:2:1 (soil: compost: sand) and put into 25.4 mm2 polyethylene bag. Organic fertilizer of 10 ml were added twice a week, while inorganic fertilizer was applied at the rate of 3 g per polyethylene bag of soil three weeks after sowing. Treatment without fertilizer application was established as a control. The treatments were laid in a split-split plot design with three replications. Plant growth was assessed using accumulating plant height, fresh weight and dry weight. The application of organic plus inorganic fertilizer had significant effects on plant height. The application of organic fertilizer combination with cow dung gave significant difference to plant mass (fresh and dry). The data obtained from these treatments were significantly higher than the data obtained from the control (without fertilizer). In conclusion, the type of compost did not gave significant difference towards plant height while it only gave significant difference towards plant mass.

    Young overweight women are at risk of iron and zinc deficiency. This study assessed iron, zinc and inflammatory status during a 12-month weight loss trial in young women (18-25 y; BMI >=27.5 kg/m2) randomised to a higher-protein (HP: 32% protein; 12.2 mg/day iron; 11.7 mg/day zinc) or lower-protein (LP: 20%; 9.9 mg/day; 7.6 mg/day respectively) diet with contrasting haem iron and zinc content. In completers (HP: n=21; LP: n=15), HP participants showed higher median ferritin (52.0 vs 39.0 μg/L; p=0.021) and lower median soluble transferrin receptor-ferritin index (sTfR-F; 0.89 vs 1.05; p=0.024) although concentrations remained within normal range for both diets. Median C-reactive protein (CRP; HP: 3.54; LP: 4.63 mg/L) and hepcidin (HP: 5.70; LP: 8.25 ng/mL) were not elevated at baseline, and no longitudinal between-diet differences were observed for zinc and CRP. Compared to those with =10% weight showed lower median sTfR-F (0.76 vs 1.03; p=0.019) at six months. Impact of >=10% weight loss on iron was more apparent in LP participants who exhibited greater mean serum iron (20.0 vs 13.5 μmol/L; p=0.002), transferrin saturation (29.8% vs 19.4%; p=0.001) and lower sTfR (1.24 vs 1.92 mg/L; p=0.034) at 12 months. Results show normal iron and zinc status can be maintained during 12 months of energy restriction. In the absence of elevated baseline inflammation and hepcidin, a more favourable iron profile in those with >=10% weight loss may reflect stronger compliance or the potential influence of iron regulatory mechanisms unrelated to inflammatory hepcidin reduction.

    Full Text Available Abstract: Objective: Diabetes Mellitus is a group of common metabolic disorders that share the phenotype of hyperglycemia. Type 2 diabetes mellitus is a familial disease with a lifetime risk of 40% if one parent has Type 2 diabetes23 . Overweight is the second risk factor for type 2 diabetes mellitus and as many as 80% of patients with Type 2 Diabetes are Obese. Till now, very few studies have shown early outcome of genetic transmission on cardiac autonomic activity among healthy offsprings with parental type 2 diabetes mellitus. Thus, the aim of this study was to examine the impact of parental Type 2 diabetes on autonomic nervous system and to determine whether autonomic neuropathy is present and its association with glycemic status, weight and height. Method: The cross-sectional study of Height, Weight, Glycemic status and Cardiovascular Autonomic Functions was carried out in 30 healthy offsprings of Type 2 Diabetic Parents (Study group and 30 healthy offsprings of Nondiabetic Parents (Control group in the age range of 18 - 21 years randomly selected among 1st MBBS students. Statistical Analysis is done by and lsquo;Z' test. Results: There is insignificant decrease in parasympathetic functions and insignificant increase in Fasting and Postload Blood Glucose in Study Group compared to Control Group. There significant increase in weight, and height of subjects of Study Group compared to Control. Conclusion:Our observations indicate that subclinical autonomic dysfunction may develop without the presence of long-term hyperglycemia in family members of type 2 diabetic subjects; Thus, it is not simply a complication of the hyperglycemia in these patients. An explanation could be that it is possible to inherit susceptibility genes for autonomic neuropathy, and that these genes could be expressed before or maybe even without the subjects developing diabetes. Insulin resistance is a function of fat mass and because increasing body weight in the

    Objectives To examine the relationship between maternal stress, work status, concern about child weight, and the use of restrictive feeding practices among mothers of preschool children. Methods 285 mothers of 2-to-5-year-old children completed an on-line survey. Questions included demographics, items from the Depression Anxiety Stress Scale, and the Child Feeding Questionnaire. Linear regression and ANOVA examined the relationship between maternal stress, work hours, concern about child weight, and the use of restrictive practices for one 2-to-5-year-old child living within the home. Results Mothers were 32.6 ± 5.2 years of age and spent 39.7 ± 12.0 h/week at work. Seventy-one percent worked full time. Children were 3.4 ± 1.0 years of age and 51% male. Stress (3.41 ± 0.77, p ≤ 0.001) and concern about child weight (3.41 ± 0.77, p ≤ 0.00) were associated with the use of restrictive feeding practices. Mothers with severe/extremely severe stress used restriction more than mothers with normal stress, respectively (3.63 ± 0.80, 3.30 ± 0.81, p = 0.03). No difference was found among mothers with mild/moderate stress (3.50 ± 0.63, p = 0.06). There was no association between work hours (p = 0.50) or work status (p = 0.91) and the use of restrictive feeding practices. Conclusions Maternal stress and concern about child weight were associated with the use of restrictive feeding practices. Considering the current rates of childhood obesity in the United States, understanding factors that influence a child's food environment is advantageous and can help improve maternal and child health.

    The objective was to examine longitudinal 4-year-relationships between neighbourhood social environment and children’s body mass index-standard deviation score (BMI-SDS) taking into account the built environment. Furthermore, we have analysed the influence of potential interactions between the social environment and family/social data on children’s BMI-SDS. Between 2006–2008 and 2010–2012, anthropometric measurements were conducted among 485 children (age at baseline: 6.1 (5.8–6.4)). Socio-demographic characteristics and perception of residential environment were reported by parents. Geographic Information Systems were used to examine street length, number of food outlets and distance to the nearest playground and park/green space within an 800 m Euclidian buffer of each participant address point. Additional data on neighbourhood characteristics (e.g., traffic density, walkability, crime rates) were obtained from the State Capital of Kiel, Germany. In a multivariate model, walkability, street type, socioeconomic status of the district and perceived frequency of passing trucks/busses were associated with BMI-SDS over 4 years, but only neighbourhood SES had an effect on change in BMI-SDS. However, familial/social factors rather than neighbourhood environment (especially social environment) had an impact on children’s BMI-SDS over 4 years. Thus, social inequalities in childhood overweight are only partially explained by social neighbourhood environment. PMID:24132135

    Full Text Available There is a dearth of research on the long-term efficacy and safety of treatments for adolescent obesity. This narrative review examined several approaches to treatment, focusing on long-term effectiveness data in adolescents, as well as relevant findings from studies of adults. The available research suggests that lifestyle modification has promise in obese adolescents, although it is not clear that any particular dietary or physical activity approach is more effective than another. Meal replacements are quite effective in adults and deserve further research in adolescents. Extending the length of treatment to teach weight loss maintenance skills is likely to improve long-term outcomes in adolescents, and delivering treatment via the Internet or telephone is a novel way of doing so. Treatment that combines lifestyle modification with the medication orlistat generally appears to be safe but only marginally superior to lifestyle modification alone. More research is needed on the management of adolescent obesity, which has been overlooked when compared with research on the treatment of obesity in children and adults.

    Breakfast has been labeled the most important meal of the day, but are there data to support this claim? We summarized the results of 47 studies examining the association of breakfast consumption with nutritional adequacy (nine studies), body weight (16 studies), and academic performance (22 studies) in children and adolescents. Breakfast skipping is highly prevalent in the United States and Europe (10% to 30%), depending on age group, population, and definition. Although the quality of breakfast was variable within and between studies, children who reported eating breakfast on a consistent basis tended to have superior nutritional profiles than their breakfast-skipping peers. Breakfast eaters generally consumed more daily calories yet were less likely to be overweight, although not all studies associated breakfast skipping with overweight. Evidence suggests that breakfast consumption may improve cognitive function related to memory, test grades, and school attendance. Breakfast as part of a healthful diet and lifestyle can positively impact children's health and well-being. Parents should be encouraged to provide breakfast for their children or explore the availability of a school breakfast program. We advocate consumption of a healthful breakfast on a daily basis consisting of a variety of foods, especially high-fiber and nutrient-rich whole grains, fruits, and dairy products.

    This aim was to examine differences on lumbar lordosis and thoracic kyphosis in standing position by gender, age and weight status in healthy subjects using a noninvasive method. A total of 297 women (36.6 ± 7.3 years) and 362 men (39.8 ± 7.5 years) participated in this study. Participants were categorized according to the international BMI (kg/m2) cut-off points. Age was stratified by ten years increments starting from 20 y. Men showed smaller lumbar lordosis (17.3 ± 9.3) and larger thoracic kyphosis (42.8 ± 8.8°) than women (29.6 ± 11.3 and 40.4 ± 9.5° respectively; both p curvature. The results of this study suggest that gender could be the only determinant factor of lumbar lordosis in healthy people.

    To examine associations between various measures of the food environment and BMI percentile among youth. Cross-sectional, observational. Pitt County, eastern North Carolina. We extracted the electronic medical records for youth receiving well child check-ups from January 2007 to June 2008. We obtained addresses for food venues from two secondary sources and ground-truthing. A geographic information systems database was constructed by geocoding home addresses of 744 youth and food venues. We quantified participants' accessibility to food venues by calculating 'coverage', number of food venues in buffers of 0·25, 0·5, 1 and 5 miles (0·4, 0·8, 1·6 and 8·0 km) and by calculating 'proximity' or distance to the closest food venue. We examined associations between BMI percentile and food venue accessibility using correlation and regression analyses. There were negative associations between BMI percentile and coverage of farmers' markets/produce markets in 0·25 and 0·5 mile Euclidean and 0·25, 0·5 and 1 mile road network buffers. There were positive associations between BMI percentile and coverage of fast-food and pizza places in the 0·25 mile Euclidean and network buffers. In multivariate analyses adjusted for race, insurance status and rural/urban residence, proximity (network distance) to convenience stores was negatively associated with BMI percentile and proximity to farmers' markets was positively associated with BMI percentile. Accessibility to various types of food venues is associated with BMI percentile in eastern North Carolina youth. Future longitudinal work should examine correlations between accessibility to and use of traditional and non-traditional food venues.

    University students are potentially important targets for the promotion of healthy lifestyles as this may reduce the risks of lifestyle-related disorders later in life. This cross-sectional study examined differences in eating behaviours, dietary intake, weight status, and body composition between male and female university students. A total of 584 students (59.4% females and 40.6% males) aged 20.6 +/- 1.4 years from four Malaysian universities in the Klang Valley participated in this study. Participants completed the Eating Behaviours Questionnaire and two-day 24-hour dietary recall. Body weight, height, waist circumference and percentage of body fat were measured. About 14.3% of males and 22.4% of females were underweight, while 14.0% of males and 12.3% of females were overweight and obese. A majority of the participants (73.8% males and 74.6% females) skipped at least one meal daily in the past seven days. Breakfast was the most frequently skipped meal. Both males and females frequently snacked during morning tea time. Fruits and biscuits were the most frequently consumed snack items. More than half of the participants did not meet the Malaysian Recommended Nutrient Intake (RNI) for energy, vitamin C, thiamine, riboflavin, niacin, iron (females only), and calcium. Significantly more males than females achieved the RNI levels for energy, protein and iron intakes. This study highlights the presence of unhealthy eating behaviours, inadequate nutrient intake, and a high prevalence of underweight among university students. Energy and nutrient intakes differed between the sexes. Therefore, promoting healthy eating among young adults is crucial to achieve a healthy nutritional status.

    Full Text Available BACKGROUND: Current data on the prevalence of overweight and energy-balance behaviors among European children is necessary to inform overweight prevention interventions. METHODOLOGY/PRINCIPAL FINDINGS: A school-based survey among 10-12 year old children was conducted in seven European countries using a standardized protocol. Weight, height, and waist circumference were measured; Engagement in physical activity, sedentary and dietary behaviors, and sleep duration were self-reported. Descriptive analyses were conducted, looking at differences according to country, gender, and parental education. 7234 children (52%girls; 11.6 ± 0.7 years participated. 25.8% and 5.4% of boys, and 21.8% and 4.1% of girls were overweight (including obese and obese (according to International Obesity Task Force criteria, respectively. Higher prevalence of overweight/obesity was observed in Greece, Hungary, Slovenia and Spain than in Belgium, Netherlands and Norway. Large differences between countries were found in intakes of sugar-sweetened beverages, breakfast, active transport, TV and computer time. More favorable overweight status and behavior patterns were found in girls than boys and in children of higher educated parents than in children of lower educated parents. CONCLUSIONS/SIGNIFICANCE: High levels and striking differences in overweight status and potential risk behaviors were found among schoolchildren across Europe.

    Differences in the direction and degree to which invasive alien and native plants are influenced by mycorrhizal associations could indicate a general mechanism of plant invasion, but whether or not such differences exist is unclear. Here, we tested whether mycorrhizal responsiveness varies by plant invasive status while controlling for phylogenetic relatedness among plants with two large grassland datasets. Mycorrhizal responsiveness was measured for 68 taxa from the Northern Plains, and data for 95 taxa from the Central Plains were included. Nineteen percent of taxa from the Northern Plains had greater total biomass with mycorrhizas while 61% of taxa from the Central Plains responded positively. For the Northern Plains taxa, measurable effects often depended on the response variable (i.e., total biomass, shoot biomass, and root mass ratio) suggesting varied resource allocation strategies when roots are colonized by arbuscular mycorrhizal fungi. In both datasets, invasive status was nonrandomly distributed on the phylogeny. Invasive taxa were mainly from two clades, that is, Poaceae and Asteraceae families. In contrast, mycorrhizal responsiveness was randomly distributed over the phylogeny for taxa from the Northern Plains, but nonrandomly distributed for taxa from the Central Plains. After controlling for phylogenetic similarity, we found no evidence that invasive taxa responded differently to mycorrhizas than other taxa. Although it is possible that mycorrhizal responsiveness contributes to invasiveness in particular species, we find no evidence that invasiveness in general is associated with the degree of mycorrhizal responsiveness. However, mycorrhizal responsiveness among species grown under common conditions was highly variable, and more work is needed to determine the causes of this variation.

    Childhood obesity is a multifactorial disease, in which unhealthy dietary patterns and sedentary lifestyles play a decisive role. The aim of this study was to assess the weight status, dietary habits and physical activity in Castile-La Mancha children. A cross-sectional study was conducted on 3061 children 6-12 years-old who were participating in the programme, "Alimenta su salud". Anthropometric measurements, food consumption frequency, dietary habits and physical activity were assessed by a questionnaire, including gender, age and geographical influences. The prevalence of subjects with excess weight-for-height was 24.0% and obesity was 14.3%, with geographical differences. Girls more often have mid-morning snacks, consume more supplements, and reported to be less active than boys. Special diets and sports activities were lower in children aged 6-9 years as compared to the 10-12 years old group. The intake of vegetables and fruit is low, while there is overconsumption of sausages, pastries, salted snacks, sweets and fast food, with some differences by age group. One out of four children is overweight or obese in this population. Children do not meet recommendations for fruit and vegetables and there is a high consumption of foods associated with obesity risk. Physical inactivity was more prevalent during the weekends, and among girls. Copyright © 2010 Asociación Española de Pediatría. Published by Elsevier Espana. All rights reserved.

    Background: Body-related teasing is known to be linked to body dissatisfaction and dieting behavior in adolescents. However, little is known about it in non-Western countries. This study aims to examine the prevalence of body-related teasing among Japanese adolescents and its connection to weight status, body image, and dieting behavior to consider implications for public health. Methods: The design of this study is a cross-sectional study. An anonymous self-administrated survey was conducted with 1172 junior high school students in Higashi-Osaka City in Osaka Prefecture in Japan. The sampling method was non-random design. The survey items included self-reported height and weight, history and source of teasing, body image perception, and dieting behavior. A chi-square test and logistic regression analysis were used to examine the associations. Results: A history of teasing was reported by 16.4% of boys and 32.5% of girls (P Body-related teasing has a significant association with body image and dieting behavior in Japanese adolescents. A school-based education should be provided to reduce body-related teasing.

    Purpose Previous research on the influence of the food environment on weight status has often used impersonal measures of the food environment defined for residential neighborhoods, which ignore whether people actually use the food outlets near their residence. To assess whether supermarkets are relevant contexts for interventions, the present study explored between-residential neighborhood and between-supermarket variations in body mass index (BMI) and waist circumference (WC), and investigated associations between brands and characteristics of supermarkets and BMI or WC, after adjustment for individual and residential neighborhood characteristics. Methods Participants in the RECORD Cohort Study (Paris Region, France, 2007–2008) were surveyed on the supermarket (brand and exact location) where they conducted their food shopping. Overall, 7 131 participants shopped in 1 097 different supermarkets. Cross-classified multilevel linear models were estimated for BMI and WC. Results Just 11.4% of participants shopped for food primarily within their residential neighborhood. After accounting for participants' residential neighborhood, people shopping in the same supermarket had a more comparable BMI and WC than participants shopping in different supermarkets. After adjustment for individual and residential neighborhood characteristics, participants shopping in specific supermarket brands, in hard discount supermarkets (especially if they had a low education), and in supermarkets whose catchment area comprised low educated residents had a higher BMI/WC. Conclusion A public health strategy to reduce excess weight may be to intervene on specific supermarkets to change food purchasing behavior, as supermarkets are where dietary preferences are materialized into definite purchased foods.

    Full Text Available The objective of forest management in the tropics, in recent decades, has shifted from timber production to biodiversity conservation and maintenance of life support system. However, past forestry practices have greatly influenced the structure of plant communities, preponderance of foreign invasive species, populations of high value medicinal plants as well as other non-wood forest products. We assessed the abundance and distribution of medicinal plants in managed and undisturbed forests of Dehradun Forest Division (DFD, Uttarakhand (India. A total of 80 transects (each 1 km long were laid in various categories of forest types in DFD. This paper deals with distribution, availability and regeneration status of five commercially important species viz., Justicia adhatoda, Aegle marmelos, Phyllanthus emblica, Terminalia bellirica and Terminalia chebula, across different forest types. The study reveals that open canopy forest patches, Lantana infested patches and Acacia catechu-Dalbergia sissoo (Khair -Shisam woodlands in the eastern part of the DFD have excellent potential for the production and sustainable harvest of Justicia adhatoda. Areas those are less suitable for timber production viz., open hill forests, have greater potential for conservation and development of Aegle marmelos, Phyllanthus emblica and Terminalia bellirica. For the production and management of high value medicinal plants in the DFD these ecological considerations need to be kept in mind.

    Full Text Available Antioxidants are substances that slow down the oxidation of organic compounds that protect the body from the negative effects of free radicals antioxidant connected with free radical and puts up a barrier to the corrosive effects of the electron. Enzyme protective system of the body converts cell oxidant into the water and oxygen.The body has its own system of struggle with excessive amounts of free radicals, but it has weakened under the impact of the polluted environment, direct sunlight and needs support. Scientists found that many plants contain substances flavonoids - a large group of polyphenolic compounds structure, which bind free radicals.This article presents a review of research performed in the Russian state endowment of the University of Immanuel Kant, the influence of chemical contaminated areas in the antioxidant status of the plants.Thus the study of the influence of factors on the formation of antioxidants plants is a fragment of a large-scale work on the study of natural antioxidants, which not only protect living organisms but also determine the quality of plant foods, feeds, and ultimately the quality of life and its duration. The solution of the problems of modern society - environmental, health, demography is impossible without change of attitude to food.

    Experiments were conducted to study the arbuscular mycorrhizal (AM) status and its role in P-uptake through assay of root phosphatases activities in four varieties of male Carica papaya L. viz. CO-1, CO-2, Honey Dew and Washington during flowering stages. In the present study, mean total root colonization of AM fungi recorded peak increase in flowering stage-II while mean root phosphatase (acid and alkaline) activities recorded peak increase in flowering stage-I. Unlike root colonization and root phosphatase activities, spore density did not exhibit any definite patterns and recorded a narrow range of fluctuation during different flowering stages of male C. papaya. The study brought out the fact that root colonization and spore density of AM fungi along with root phosphatase activities varied significantly within the four varieties of male C. papaya plants during each flowering stage. The study also recorded consistently higher acid root phosphatase activity than alkaline root phosphatase activity under P-deficient, acidic soil conditions during all flowering stages of male C. papaya plants. Studies revealed that the root colonization of AM fungi influenced root phosphatase activities (acid and alkaline) positively and significantly during all flowering stages of male C. papaya plants. A total of twelve species of AM fungi belonging to five genera viz. Acaulospora, Dentiscutata, Gigaspora, Glomus, and Racocetra were recovered from the rhizosphere of male C. papaya plants.

    2016-03-01

    Full Text Available Hypoxic and anoxic conditions result in the energy crisis that leads to cell damage. Since mitochondria are the primary organelles for energy production, the support of these organelles in a functional state is an important task during oxygen deprivation. Plant mitochondria adapted the strategy to survive under hypoxia by keeping electron transport operative even without oxygen via the use of nitrite as a terminal electrons acceptor. The process of nitrite reduction to nitric oxide (NO in the mitochondrial electron transport chain recycles NADH and leads to a limited rate of ATP production. The produced ATP alongside with the ATP generated by fermentation supports the processes of transcription and translation required for hypoxic survival and recovery of plants. Non-symbiotic hemoglobins (called phytoglobins in plants scavenge NO and thus contribute to regeneration of NAD+ and nitrate required for the operation of anaerobic energy metabolism. This overall operation represents an important strategy of biochemical adaptation that results in the improvement of energy status and thereby in protection of plants in the conditions of hypoxic stress.

    Background Mixed findings have been reported on the association between Western fast-food restaurants and body weight status. Results vary across study contexts and are sensitive to the samples, measures and methods used. Most studies have failed to examine the temporally dynamic associations between community exposure to fast-food restaurants and weight changes. Methods Bayesian hierarchical regressions are used to model changes in body mass index, waist-to-height ratio (WHtR) and waist-to-hip ratio (WHpR) as a function of changes in Western fast-food restaurants in 216 communities for more than 9000 Chinese adults followed up multiple times between 2000 and 2009. Results Number of Western fast-food restaurants is positively associated with subsequent increases in WHtR and WHpR among rural population. More fast-food restaurants are positively associated with a future increase in WHpR for urban women. Increased availability of fast food between two waves is related to increased WHtR for urban men over the same period. A past increase in number of fast-food restaurants is associated with subsequent increases in WHtR and WHpR for rural population. Conclusions The associations between community exposure to Western fast food and weight changes are temporally dynamic rather than static. Improved measures of exposure to community environment are needed to achieve more precise estimates and better understanding of these relationships. In light of the findings in this study and China’s rapid economic growth, further investigation and increased public health monitoring is warranted since Western fast food is likely to be more accessible and affordable in the near future.

    Meal planning could be a potential tool to offset time scarcity and therefore encourage home meal preparation, which has been linked with an improved diet quality. However, to date, meal planning has received little attention in the scientific literature. The aim of our cross-sectional study was to investigate the association between meal planning and diet quality, including adherence to nutritional guidelines and food variety, as well as weight status. Meal planning, i.e. planning ahead the foods that will be eaten for the next few days, was assessed in 40,554 participants of the web-based observational NutriNet-Santé study. Dietary measurements included intakes of energy, nutrients, food groups, and adherence to the French nutritional guidelines (mPNNS-GS) estimated through repeated 24-h dietary records. A food variety score was also calculated using Food Frequency Questionnaire. Weight and height were self-reported. Association between meal planning and dietary intakes were assessed using ANCOVAs, while associations with quartiles of mPNNS-GS scores, quartiles of food variety score and weight status categories (overweight, obesity) were evaluated using logistic regression models. A total of 57% of the participants declared to plan meals at least occasionally. Meal planners were more likely to have a higher mPNNS-GS (OR quartile 4 vs. 1 = 1.13, 95% CI: [1.07-1.20]), higher overall food variety (OR quartile 4 vs. 1 = 1.25, 95% CI: [1.18-1.32]). In women, meal planning was associated with lower odds of being overweight (OR = 0.92 [0.87-0.98]) and obese (OR = 0.79 [0.73-0.86]). In men, the association was significant for obesity only (OR = 0.81 [0.69-0.94]). Meal planning was associated with a healthier diet and less obesity. Although no causality can be inferred from the reported associations, these data suggest that meal planning could potentially be relevant for obesity prevention.

    Full Text Available Abstract Background Heavy alcohol consumption during adolescence has many known harmful health and social consequences and is strongly associated with numerous health risk behaviours. The consequences of heavy alcohol use during adolescence on nutritional status, specifically growth and weight status are largely unknown at this time. Methods Substance use, anthropometric indices of growth and weight, dietary energy intake and physical activity in heavy drinking adolescents (meeting DSM-IV criteria for alcohol use disorders and matched light/non-drinking control adolescents were assessed. Results Lifetime alcohol dose, measured in standard drinks of alcohol, was orders of magnitude higher in adolescents with alcohol use disorders (AUDs compared to controls. The AUDs group was selected to represent relatively 'pure' AUDs, with minimal other drug use and no psychiatric diagnoses. The growth and weight status of adolescents with AUDs were generally comparable to that of controls, and is in line with the growth and weight status of the South African adolescent population. A greater proportion of overweight/obese females was found in both groups, with this percentage tending to be greater, although not significantly so, in the AUDs group. Adolescent females with AUDs had increased odds of being overweight/obese compared to controls, after adjustment for smoking, physical activity and energy intake. Conclusion Anthropometric indices of growth and weight status of participants in the Control and AUD groups were generally comparable. Female adolescents with AUDs may have an increased risk of being overweight/obese compared to adolescent females without AUDs. The presence of an AUD in our adolescent sample was associated with higher energy intake. Longitudinal studies are needed to elucidate the effects of heavy alcohol use on energy balance, growth and weight status in adolescents as they age. Nonetheless, the current study contributes to our

    In current debates on emerging technologies for plant breeding in Europe, much attention has been given to the regulatory status of these techniques and their public acceptance. At present, both genetically modified plants with cisgenic approaches-using genes from crossable species-as well as transgenic approaches-using genes from different species-fall under GMO regulation in the EU and both are mandatorily labelled as GMOs. Researchers involved in the early development of cisgenic GM plants convey the message that the potential use and acceptance of cisgenic approaches will be seriously hindered if GMO regulations are not adjusted. Although the similar treatment and labelling of transgenic and cisgenic plants may be a legitimate concern for the marketability of a cisgenic GM plant, there are concerns around their commercialization that reach beyond the current focus on (de)regulation. In this paper, we will use the development of the cisgenic GM potato that aims to overcome 'late blight'-the most devastating potato disease worldwide-as a case to argue that it is important to recognize, reflect and respond to broader concerns than the dominant focus on the regulatory 'burden' and consumer acceptance. Based on insights we gained from discussing this case with diverse stakeholders within the agricultural sector and potato production in Norway during a series of workshops, we elaborate on additional issues such as the (technical) solution offered; different understandings of the late blight problem; the durability of the potato plant resistance; and patenting and ownership. Hence, this paper contributes to empirical knowledge on stakeholder perspectives on emerging plant breeding technologies, underscoring the importance to broaden the scope of the debate on the opportunities and challenges of agricultural biotechnologies, such as cisgenic GM plants. The paper offers policy-relevant input to ongoing efforts to broaden the scope of risk assessments of agricultural

    This work aimed to evaluate, in vitro, the capability of roots of two salt marsh plants to release low molecular weight organic acids (LMWOAs) and to ascertain whether Cu contamination would stimulate or not organic acids exudation. The sea rush Juncus maritimus and the sea-club rush Scirpus maritimus, both from the lower Douro river estuary (NW Portugal), were used. Plants were collected seasonally, four times a year in 2004, during low tide. After sampling, plant roots were washed for removal of adherent particles and immersed for 2 h in a solution that matched salinity (3) and pH (7.5) of the pore water from the same location to obtain plant exudates. In one of the seasons, similar experiments were carried out but spiking the solution with different amounts of Cu in order to embrace the range between 0 and 1600 nM. In the final solutions as well as in sediment pore water LMWOAs were determined by high performance liquid chromatography. Plants were able to release, in a short period of time, relatively high amounts of LMWOAs (oxalate, citrate, malate, malonate, and succinate). In the sediment pore water oxalate, succinate and acetate were also detected. Therefore, plant roots probably contributed to the presence of some of these organic compounds in pore water. Exudation differed between the plant species and also showed some seasonally variation, particularly for S. maritimus. The release of oxalate by J. maritimus increased with Cu increase in the media. However, exudation of the other LMWOAs did not seem to be stimulated by Cu contamination in the media. This fact is compatible with the existence of alternative internal mechanisms for Cu detoxification, as denoted by the fact that in media contaminated with Cu both plant species accumulated relatively high amounts (29-83%) of the initially dissolved Cu. This study expands our knowledge on the contribution of globally dominant salt marsh plants to the release of LMWOAs into the environment.

    The nutrient status of forest soils in the Mexico City Air Basin was evaluated by observing plant growth responses to fertilization with N, P or both nutrients combined. P deficiency was the most frequent condition for soil from two high pollution sites and N deficiency was greatest at a low N deposition site. Concentrations of Pb and Ni, and to a lesser extent Zn and Co, were higher at the high pollution sites. However, positive plant growth responses to P and sometimes to N, and results of wheat root elongation bioassays, suggest that heavy metal concentrations were not directly phytotoxic. Further studies are needed to determine if heavy metal toxicity to mycorrhizal symbionts of eucalyptus (Eucalyptus camaldulensis Dehnh.) from high pollution sites may explain the P deficiency and stunted growth. P deficiency is expected to limit the capacity for biotic N retention in N saturated forested watersheds in the Basin of Mexico dominated by Andisols. - Plant response to N deposition may be limited by P limitation in forests growing on Andisol soils in the Basin of Mexico.

    The effect of addition of the nitric oxide donor S-nitrosoglutathione (GSNO) on the Zn nutritional status was evaluated in hydroponically-cultured wheat plants (Triticum aestivum cv. Chinese Spring). Addition of GSNO in Zn-deprived plants did not modify biomass accumulation but accelerated leaf senescence in a mode concomitant with accelerated decrease of Zn allocation to shoots. In well-supplied plants, Zn concentration in both roots and shoots declined due to long term exposure to GSNO. A further evaluation of net Zn uptake rate (ZnNUR) during the recovery of long-term Zn-deprivation unveiled that enhanced Zn-accumulation was partially blocked when GSNO was present in the uptake medium. This effect on uptake was mainly associated with a change of Zn translocation to shoots. Our results suggest a role for GSNO in the modulation of Zn uptake and in root-to-shoot translocation during the transition from deficient to sufficient levels of Zn-supply.

    Limited research shows an inconclusive association between soda intake and asthma, potentially attributable to certain preservatives in sodas. This cross-sectional study examined the association between regular (nondiet)-soda intake and current asthma among a nationally representative sample of high school students. Analysis was based on the 2009 national Youth Risk Behavior Survey and included 15,960 students (grades 9 through 12) with data for both regular-soda intake and current asthma status. The outcome measure was current asthma (ie, told by doctor/nurse that they had asthma and still have asthma). The main exposure variable was regular-soda intake (ie, drank a can/bottle/glass of soda during the 7 days before the survey). Multivariable logistic regression was used to estimate the adjusted odds ratios for regular-soda intake with current asthma after controlling for age, sex, race/ethnicity, weight status, and current cigarette use. Overall, 10.8% of students had current asthma. In addition, 9.7% of students who did not drink regular soda had current asthma, and 14.7% of students who drank regular soda three or more times per day had current asthma. Compared with those who did not drink regular soda, odds of having current asthma were higher among students who drank regular soda two times per day (adjusted odds ratio=1.28; 95% CI 1.02 to 1.62) and three or more times per day (adjusted odds ratio=1.64; 95% CI 1.25 to 2.16). The association between high regular-soda intake and current asthma suggests efforts to reduce regular-soda intake among youth might have benefits beyond improving diet quality. However, this association needs additional research, such as a longitudinal examination.

    Full Text Available ObjectiveFood cues are omnipresent in the daily environment and may influence eating behavior even non-consciously. An increased reactivity to food cues, such as food odors, has been shown to be correlated with obesity in children. The objective of this study is to investigate whether the non-conscious influence of food odors on children’s food choices varies by their weight status.MethodsSeventy-four children, of whom 29 were obese, took part in this study. The children performed a food choice intention task presented as a computer game in which 30 pairs of food images (a fatty-sweet food picture vs. a fruit picture successively appeared on the screen. The children had to choose the item “they most wanted to eat at the present moment” for each pair. While performing this task, the children wore a headset in which the microphone foam was odorized with a fruity odor, a fatty-sweet odor or no odor. They performed the intention task three times, one time for each olfactory condition. The odors were non-attentively perceived, i.e., none of the children were aware of the odorization of the microphone foams. The modeled probability is the probability to choose a fruit.ResultsIn children with obesity, the fruity odor increased the likelihood of a fruit to be chosen compared to the no-odor condition [OR (95% CL = 1.42 (1.13–1.78, P = 0.0028], while the fatty-sweet odor had no effect on food choice [OR (95% CL = 1.07 (0.85–1.36, P = 0.55]. In children without obesity, both the fruity and the fatty-sweet odors decreased the likelihood to choose a fruit compared to the no-odor condition [OR (95% CL = 0.76 (0.64–0.90, P = 0.0015, for the fruity odor and OR (95% CL = 0.79 (0.66–0.93, P = 0.0062, for the fatty-sweet odor].ConclusionThe different patterns of results obtained in both groups of children suggest differences in the mental representations activated by non-attentively perceived olfactory cues based on

    Silicon (Si) is a nonessential, beneficial micronutrient for plants. It increases the plant stress tolerance in relation to its accumulation capacity. In this work, root Si transporter genes were characterized in 17 different plants and inferred for their Si-accumulation status. A total of 62 Si transporter genes (31 Lsi1 and 31 Lsi2) were identified in studied plants. Lsi1s were 261-324 residues protein with a MIP family domain whereas Lsi2s were 472-547 residues with a citrate transporter family domain. Lsi1s possessed characteristic sequence features that can be employed as benchmark in prediction of Si-accumulation status/capacity of the plants. Silicic acid selectivity in Lsi1s was associated with two highly conserved NPA (Asn-Pro-Ala) motifs and a Gly-Ser-Gly-Arg (GSGR) ar/R filter. Two NPA regions were present in all Lsi1 members but some Ala substituted with Ser or Val. GSGR filter was only available in the proposed high and moderate Si accumulators. In phylogeny, Lsi1s formed three clusters as low, moderate and high Si accumulators based on tree topology and availability of GSGR filter. Low-accumulators contained filters WIGR, AIGR, FAAR, WVAR and AVAR, high-accumulators only with GSGR filter, and moderate-accumulators mostly with GSGR but some with A/CSGR filters. A positive correlation was also available between sequence homology and Si-accumulation status of the tested plants. Thus, availability of GSGR selectivity filter and sequence homology degree could be used as signatures in prediction of Si-accumulation status in experimentally uncharacterized plants. Moreover, interaction partner and expression profile analyses implicated the involvement of Si transporters in plant stress tolerance.

    Full Text Available PURPOSE: Previous research on the influence of the food environment on weight status has often used impersonal measures of the food environment defined for residential neighborhoods, which ignore whether people actually use the food outlets near their residence. To assess whether supermarkets are relevant contexts for interventions, the present study explored between-residential neighborhood and between-supermarket variations in body mass index (BMI and waist circumference (WC, and investigated associations between brands and characteristics of supermarkets and BMI or WC, after adjustment for individual and residential neighborhood characteristics. METHODS: Participants in the RECORD Cohort Study (Paris Region, France, 2007-2008 were surveyed on the supermarket (brand and exact location where they conducted their food shopping. Overall, 7 131 participants shopped in 1 097 different supermarkets. Cross-classified multilevel linear models were estimated for BMI and WC. RESULTS: Just 11.4% of participants shopped for food primarily within their residential neighborhood. After accounting for participants' residential neighborhood, people shopping in the same supermarket had a more comparable BMI and WC than participants shopping in different supermarkets. After adjustment for individual and residential neighborhood characteristics, participants shopping in specific supermarket brands, in hard discount supermarkets (especially if they had a low education, and in supermarkets whose catchment area comprised low educated residents had a higher BMI/WC. CONCLUSION: A public health strategy to reduce excess weight may be to intervene on specific supermarkets to change food purchasing behavior, as supermarkets are where dietary preferences are materialized into definite purchased foods.

    The extreme summer drought and heat waves that occurred in South-Europe in 2003 and 2012 have led to the loss of more than 50% of winery production in the Classic Karst (NE Italy). The irrigation of vineyards in this area is not appropriately developed and, when used, it does not consider the actual water status and needs of plants, posing risks of inappropriate or useless usage of large water volumes. The predicted future increase in frequency and severity of extreme climate events poses at serious risk the local agriculture based on wine business. We monitored seasonal trends of pre-dawn (Ψpd) and minimum (Ψmin) leaf water potential, and stomatal conductance (gL) of 'Malvasia' grapevine in one mature (MV, both in 2015 and 2016) and one young vineyard (YV, in 2016). Moreover, we extracted xylem sap form plant stems and soil water from samples collected in nearby caves, by cryo-vacuum distillation. We also collected precipitation and irrigation water in different months. Oxygen isotope composition (δ18O) of atmospheric, plant, soil and irrigation water was analyzed to get information about rooting depth. In 2015, at the peak of summer aridity, two irrigation treatments were applied according to traditional management practices. The treatments were performed in a sub-area of the MV, followed by physiological analysis and yield measurements at grape harvest. In 2016, the soil water potential (Ψsoil) at 50 cm depth was also monitored throughout the season. Under harsh environmental conditions the apparently deep root system ensured relatively favorable plant water status in both MV and YV and during both growing seasons. The Ψsoil at 50 cm depth gradually decreased as drought progressed, reaching a minimum value of about -1.7 MPa, far more negative than Ψpd recorded in plants (about -0.5 MPa). In July, significant stomatal closure was observed, but Ψmin never surpassed the critical threshold of -1.3 MPa, indicating that irrigation was not needed. The xylem sap

    Qilian Mountains are the water source region for the low arid reaches of HeiHe river basin (Gansu province, NW China). Due to overstocking and overgrazing during the last decades adverse ecological ef¬fects, in particular on soil properties and hydrological cycle, are to be expected in growing land areas. Vegetation cover is very important to prevent erosion process and to sustain stable subsurface runoff and ground water flow. The aim of this research is to identify plant communities, detecting grazing-induced and spatially differentiated changes in vegetation patterns, and to evaluate status of pasture land degradation.The study area is located in the spring/autumn pasture area of South Qilian Mountains between 2600-3600 m a.s.l., covering five main vegetation types: spruce forest, alpine shrubland, shrubby grassland, mountain grassland, degraded mountain grassland. In order to analyze gradual changes in vegetation patterns along altitudinal and grazing gradients and to classify related plant communities, quantitative and qualitative relevé data were collected (coverage, species composition, abundance of unpalatable plants, plant functional types, etc.). Vegetation was classified using hierarchical cluster analyses. Indirect Detrended Correspondence Analysis (DCA) was used to analyze variation in relationships between vegetation, environmental factors, and grazing impact. According to DCA results, distribution of the plant communities was strongly affected by altitude and exposition. Grassland floristic gradients showed greater dependence on grazing impact, which correlated contrarily with soil organic content, soil moisture and pH. Highest numbers of species richness and alpha diversity were detected in alpine shrubland vegetation type. Comparing the monitoring data for the recent nine years, a trend of deterioration, species successions and shift in dominant species becomes obvious. Species indicating degrading site environmental conditions were identified

The main feature of psychological status of liquidators with AH was hypochondriac, depressive and anxious disorders. Controlled AHT made it possible to reach improvement in psychological status, i.e. growth of optimism and activity of patients, more often, than standard treatment in out-patient clinics. Increase in number of patients with pronounced anxious changes was observed in CG. Effi-ciency of AHT in liquidators with AH is connected with severity of depressive disturbances: in subgroups with inefficient treatment patients had the highest level of depression. In liquidators with AH, possessing neurotic disturbances, spirapril was efficient both as monotherapy, and in combina-tion with diuretic hydrochlorothiazide and beta-blocker atenolol. Conclusion. Controlled AHT in liquidators with AH has advantages over standard treatment in out-patient clinic and results in more frequent target BP level

    Birth order has been associated with childhood obesity. The objective of this cross-sectional study was to examine maternal feeding and child eating behaviors as underlying processes for increased weight status of only children and youngest siblings. Participants included 274 low-income 4-8 year old children and their mothers. The dyads completed a videotaped laboratory mealtime observation. Mothers completed the Caregiver's Feeding Styles Questionnaire and the Children's Eating Behavior Questionnaire. Child weight and height were measured using standardized procedures. Path analysis was used to examine associations of birth order, maternal feeding behavior, child eating behavior, and child overweight/obese status. The association between only child status and greater likelihood of overweight/obesity was fully mediated by higher maternal Verbal Discouragement to eat and lower maternal Praise (all p values < 0.05). The association between youngest sibling status and greater likelihood of overweight/obesity was partially mediated by lower maternal Praise and lower child Food Fussiness (all p values < 0.05). Results provide support for our hypothesis that maternal control and support and child food acceptance are underlying pathways for the association between birth order and weight status. Future findings can help inform family-based programs by guiding family counseling and tailoring of recommendations for family mealtime interactions.

    Several special status plant species occur or potentially occur at the Naval Petroleum Reserves in California (NPRC). Special status species are defined as those species that are either federally listed as endangered or threatened, or candidate taxa. Candidate species are classified as Category 1 or Category 2. Category 1 taxa are those species for which there is sufficient evidence to support listing, while Category 2 taxa are those species for which listing may possibly be appropriate, but for which sufficient data are lacking to warrant immediate listing. Determining the presence and distribution of these species on NPRC is necessary so that appropriate conservation or protection measures can be implemented. In the spring of 1988, a survey of Naval Petroleum Reserve No. 1 (NPR-1) was conducted to determine the occurrence of Hoover`s wooly-star (Eriastrum hooveri), Kern Mallow (Eremalche kemensis), San Joaquin wooly-threads (Lembertia congdonii), and California jewelflower (Caulanthus califonicus), all listed by the US Fish and Wildlife Service (FWS) as Category 2 species at that time. Of the four species, only Hoover`s wooly-star was found. It was concluded that Kern mallow and San Joaquin wooly-threads could potentially be found on NPR-1, but habitat for California jewelflower did not occur on NPR-1 and its occurrence was unlikely. As part of an ongoing effort to document the presence or absence of sensitive plant species on NPRC, surveys for species other than Hoover`s wooly-star were conducted in the spring of 1993. Abundant spring rains in 1993 created favorable growing conditions for annual forbs. Surveys in 1993 focused on potential habitat of several endangered and candidate species. The results of those surveys are presented in this report.

    Since the 1991 outage, the Doel Unit 4 nuclear power plant is known to be affected by circumferential outside diameter intergranular stress corrosion cracking at the hot leg tube expansion transition. Extensive non destructive examination inspections have shown the number of tubes affected by this problem as well as the size of the cracks to have been increasing for the three cycles up to 1993. As a result of the high percentage of tubes found non acceptable for continued service after the 1993 in-service inspection, about 1,700 mechanical sleeves were installed in the steam generators. During the 1994 outage, all the tubes sleeved during the 1993 outage were considered as potentially cracked to some extent at the upper hydraulic transition and were therefore not acceptable for continued service. They were subsequently repaired by laser welding. Furthermore all the tubes not sleeved during the 1993 outage were considered as not acceptable for continued service and were repaired by installing laser welded sleeves. During the 1995 outage, some unexpected degradation phenomena were evidenced in the sleeved tubes. This paper summarizes the status of the circumferential ODSCC experienced in the SG tubes of the Doel 4 plant as well as the other connected degradation phenomena.

    The main aim of study was to develop the environmental quality standards (EQSMP) for selected heavy metals: Pb, Cd, Hg and Ni bioaccumulated in the tissues of marine macrophytobenthic plants: Chara baltica, Cladophora spp., Coccotylus truncatus, Furcellaria lumbricalis, Polysiphonia fucoides, Stuckenia pectinata and Zanichellia palustris, collected in designated areas of the southern Baltic Sea in period 2008-2015. The calculated concentration ratios (CR), which attained very high values: 10(4)Lkg(-1) for lead, 10(3)Lkg(-1) for nickel and mercury and even 10(5)Lkg(-1) for cadmium formed the basis for the determination of EQSMP values. The EQSMP values were: 26mgkg(-1)d.w. for Pb, 33mgkg(-1)d.w. for Cd, 32mgkg(-1)d.w. for Ni and 0.4mgkg(-1)d.w. for Hg. The application of macrophytobenthic plants as bioindicators in marine environment status assessment of certain areas of the Baltic Sea is also described in the paper. Copyright © 2017 Elsevier Ltd.

    A survey was made of the arbuscular mycorrhizal (AM) status of five dominant wild plants Tamarix chinensis, Phragmites communis, Suaeda glauca, Aeluropus littoralis var. sinensis and Cirsium setosum in saline-alkaline soils of the Yellow River Delta that show low plant diversity. All of the species were colonized and showed typical AM structures (arbuscules, vesicles). The colonization percentage ranged from 0.2% to 9.5%, where C. setosum was the highest. The species richness of AMF at the different sites ranged from 2.00 to 2.40 per 50 ml soil, with an average of 2.16. Species diversity ranged from 1.99 to 2.22 per 50 ml soil, with an average of 2.13. Spore density ranged from 3 to 30 per 50 ml soil, with an average of 12. Glomus was the dominant genus, with a frequency and relative abundance of 88.1% and 68.4%, respectively. G. caledonium, with a frequency and relative abundance of 15.0% and 4.6%, respectively, was the dominant species. Differences were also observed in the distribution of AMF in different soil layers. Although there were still AM fungal spores in the layer 40 cm below the surface, most spores were found at a depth of 0-40 cm.

  8. VERTICAL LEAF SPECTRAL VARIATION AS AN INDICATOR OF NITROGEN NUTRITION STATUS IN RICE PLANTS

    2001-01-01

    A field experiment was conducted to study the response of individual leaf spectral reflectance to five levels of nitrogen fertilizer treatments in rice(Oriza sativa L.) plants. Sampling was combined through a rice canopy at upper, medium and low levels for biomass, nitrogen and water content measurements with spectral signals from the leaves. The vertical gradients of leaf biomass ,nitrogen and water contents were associated with the nitrogen availability during tillering, panicle formation, initial heading and heading. Rice plants treated with the lowest rate of N could be characterized with the lowest value of gradient in leaf biomass and leaf water content and the highest value of gradient in leaf N concentration. A spectral gradient of single reflectance(R),ratio(RVI) and normalized difference(ND) of two individual reflectances was defined as this yielded a better relationship between the spectral data and leaf nitrogen concentration. The results suggested the spectral gradients may be used as an improved diagnostic tool for nitrogen status.

    The effect of humic acids (HAs) and their iron complexes (Fe-HAs) on the input of the main mineral elements into wheat seedlings, as well as on the efficiency of photosynthesis and the lipid profile of plants, under iron deficiency has been studied. The input of iron from Fe-HA complexes and its predominant accumulation in roots are demonstrated. It is found that HAs increase the efficiency of photosynthesis due to enhanced electron transport in photosystem II. It is shown that the application of HAs and Fe-HAs is accompanied by an enhanced input of Zn into plants, which could increase the antioxidant status of plants under iron deficiency conditions. In addition, a pronounced increase in the content of lipids in plants is revealed, which is indicative of the effect of HAs on plant metabolism. The obtained results suggest that the positive effect of Fe-HAs and HAs on plants under iron deficiency conditions is due to a combination of factors, among which the effect of HAs on the antioxidant status of plants and the plant lipid metabolism predominates.

    Full Text Available Ten corn hybrids were grown on two soil types of Drava Valley in Slatina area (alluvial soil and pseudogley during two growing seasons (1998 and 1999. The ear-leaf at the beginning of silking stage was taken for chemical analysis. Micronutrient concentrations in corn leave samples were measured by ICP-AES after their microwave digestion using concentrated HNO3+H2O2. Mobile fraction of these elements in soils was also determined by ICP-AES after their extraction by ammonium acetate-EDTA. In both year of the testing, corn yields on acid soil were about 25% lower in comparison with alluvial soil. Mean concentrations of tested elements in corn leaves found in our investigations (mg kg-1 were 30.4 (Zn, 129.4 (Mn and 190.0 (Fe, respectively. In general, significant influences of growing season, soil type and genotype on Zn, Mn and Fe status in corn were found. For example, in the first year of testing higher Zn and Mn were found, as well as lower Fe concentrations in comparison with the second year. Corn growing on alluvial soil occurred due to lower Zn and Mn as well as higher Fe concentrations in plants compared to growing on pseudogley. However, these findings are not in coincidence with status of mobile fractions of Zn and Mn in the experimental plots. We presume that pH value near to neutral on alluvial soil could be responsible factor because low availability of Zn and Mn for plants occured under these conditions. An important role of heredity factors on Zn, Mn and Fe status in corn was found in our study because differences among the hybrids (mean values for two growing seasons and two soil types under identical environmental conditions were in ranges (mg kg-1 from 26.8 to 36.0 (Zn, from 98.6 to 150.4 (Mn and from 168.2 to 222.4 (Fe, respectively. It is very indicative that the first-ranged hybrid concerning grain yield (OsSK458exp: 12.34 t ha-1 is in the group characterizing low concentrations of Zn, Mn and Fe in leaves.

    The research effort is a part of the Light Water Reactor Sustainability (LWRS) Program. LWRS is a research and development program sponsored by the Department of Energy, performed in close collaboration with industry to provide the technical foundations for licensing and managing the long-term, safe and economical operation of current nuclear power plants. The LWRS Program serves to help the US nuclear industry adopt new technologies and engineering solutions that facilitate the continued safe operation of the plants and extension of the current operating licenses. The Outage Control Center (OCC) Pilot Project was directed at carrying out the applied research for development and pilot of technology designed to enhance safe outage and maintenance operations, improve human performance and reliability, increase overall operational efficiency, and improve plant status control. Plant outage management is a high priority concern for the nuclear industry from cost and safety perspectives. Unfortunately, many of the underlying technologies supporting outage control are the same as those used in the 1980’s. They depend heavily upon large teams of staff, multiple work and coordination locations, and manual administrative actions that require large amounts of paper. Previous work in human reliability analysis suggests that many repetitive tasks, including paper work tasks, may have a failure rate of 1.0E-3 or higher (Gertman, 1996). With between 10,000 and 45,000 subtasks being performed during an outage (Gomes, 1996), the opportunity for human error of some consequence is a realistic concern. Although a number of factors exist that can make these errors recoverable, reducing and effectively coordinating the sheer number of tasks to be performed, particularly those that are error prone, has the potential to enhance outage efficiency and safety. Additionally, outage management requires precise coordination of work groups that do not always share similar objectives. Outage

    At WWER-1000 NPPs, as well as at PWR NPPs, there is a problem of determining the correct weighted mean coolant temperature in the primary circuit hot legs based on the measuring channels information. The problem is caused by the coolant temperature stratification. The technical documentation for engineering support and maintenance of I and C systems does not provide any regulatory guidelines to consider this effect. Therefore, it is very important to represent a new methodology for determining the weighted mean coolant temperature in the primary circuit hot legs of the WWER-1000 reactor plants. The given paper presents the basic preconditions and approaches applied during the methodology development. They were worked out on the basis of the executed numerical and experimental research taking into account the analysis of the extensive material obtained by the authors from full-scale tests during the commissioning of WWER-1000 power units, as well as operational data obtained from several power units with different fuel loadings.

    Wetland indicator status (WIS) describes the habitat affinity of plant species and is used in wetland delineations and resource inventories. Understanding how species-level functional traits vary across WIS categories may improve designations, elucidate mechanisms of adaptation, and explain habitat optima and niche. We investigated differences in species-level traits of riparian flora across WIS categories, extending their application to indicate hydrologic habitat. We measured or compiled data on specific leaf area (SLA), stem specific gravity (SSG), seed mass, and mature height of 110 plant species that occur along the Colorado River in Grand Canyon, Arizona. Additionally, we measured leaf δ13C, δ15N, % carbon, % nitrogen, and C/N ratio of 56 species with C3 photosynthesis. We asked the following: (i) How do species-level traits vary over WIS categories? (ii) Does the pattern differ between herbaceous and woody species? (iii) How well do multivariate traits define WIS categories? (iv) Which traits are correlated? The largest trait differences among WIS categories for herbaceous species occurred for SSG, seed mass, % leaf carbon and height, and for woody species occurred for height, SSG, and δ13C. SSG increased and height decreased with habitat aridity for both woody and herbaceous species. The δ13C and hence water use efficiency of woody species increased with habitat aridity. Water use efficiency of herbaceous species increased with habitat aridity via greater occurrence of C4 grasses. Multivariate trait assemblages differed among WIS categories. Over all species, SLA was correlated with height, δ13C, % leaf N, and C/N; height was correlated with SSG and % leaf C; SSG was correlated with % leaf C. Adaptations of both herbaceous and woody riparian species to wet, frequently inundated habitats include low-density stem tissue. Adaptations to drier habitats in the riparian zone include short, high-density cavitation-resistant stem tissue, and high water use

    Full Text Available Leaf analysis is a tool for effective fertilizer recommendations in fruit trees. To achieve this goal, suitable leaf sampling method is a very important step. This study aimed to investigate leaf age, leaflet from different compound leaf positions and number of trees to be sampled as a representative sample for plant nutrient status of Longkong (Aglaia dookkoo Griff. tree. The middle pair of leaflets from the 1st, 2nd, 3rd, and 4th compound leaves from growing twigs at the lower canopy of Longkong trees were separately sampled and the following nutrients were determined: nitrogen (N, phosphorus (P, potassium (K, calcium (Ca and magnesium (Mg. The effect of soil fertility management and leaf age collected from twigs flushed at flowering and post harvest stages on nutrient concentration was investigated. Results showed that concentrations of plant nutrients in leaflets collected from different compound leaf positions were not significantly different. The leaf nutrient concentration depended on soil fertility management, higher fertilizer input resulting in higher leaf nutrient concentration. As leaf age increased, concentrations of N, P and K tended to decrease. In contrast, concentrations of Ca and Mg increased with leaf age. However, concentrations of most nutrients showed minimum variation with leaf aged 3-6 months. It is, thus, suggested that the middle pair leaflet of the 2nd compound leaf position aged 3-6 months of the lower twig should be sampled at post harvest stage from 25-35 trees to be used as a composite sample for plant nutrient analysis.

    Globally, low birth weight (LBW) remains a leading cause of neonatal and infant mortality and poses significant challenges toward the progress of achieving infant mortality-related goals. Experience from developed countries shows that two major causes of LBW (premature delivery and intrauterine growth restriction) can be averted to a great extent by adequate utilization of maternal health-care services, during pregnancy. In this study, we attempt to measure the prevalence of LBW in Zimbabwe and explore the association between adequate utilization of prenatal care (PNC) services and LBW in Zimbabwe. We also explore other possible associations with LBW. This study was based on nationally representative, cross-sectional data from Multiple Indicator Cluster Survey round 5, conducted in 2014. Participants included 3,221 mothers from both rural and urban areas. The participants were selected regardless of their current pregnancy status. Sample characteristics were presented using descriptive statistics. Association between utilization status of ANC and LBW was measured by chi-square (bivariate) test and logistic regression methods. Prevalence of LBW was 12.8%. There was 11% reduction in the odds of having LBW babies for participants from urban area when compared with rural area (AOR = 0.897; 95% CI = 0.707-1.138). When compared to women with higher education, those having primary/below primary and secondary level qualification had higher odds of experiencing LBW babies by 73 and 56%, respectively. Participants who had less than four PNC/ANC visits had 34% higher odds (AOR = 1.340; 95% CI = 1.065-1.685) than those with at least four visits, and those who had given birth more than once, had 38% lower odds (AOR = 0.620; 95% CI = 0.493-0.780) of giving birth to LBW babies when compared to those who had given birth only once. The findings of this study have programmatic and policy implications for low-resource nations and suggest that promoting access

    Nativity status/length of stay in the US has been found to be associated with obesity. However, little work has examined the role of nativity status/length of stay in excessive gestational weight gain (EGWG) in adolescents. This study utilized New York City Department of Health and Mental Hygiene birth certificate data in a cross-sectional analysis of 15,715 singleton births to primiparous teen mothers (12-19 years) between 2008 and 2010. Nativity and length of stay in the United States (US) were obtained from birth certificates. EGWG was calculated using weight at delivery and pre-pregnancy weight. Prevalence ratios were calculated through generalized estimating equations to assess the strength of the association between nativity status/length of US residence and EGWG. For US-born teens, 43 % gained more weight than recommended as compared to 32 % for foreign-born teens who have lived in the US for less than 5 years (FB teens (adjusted prevalence ratios (APR) (CI) 1.26 [1.18,1.34]), FB 10+ years (APR (CI) 1.17 [1.07,1.28]), and FB 5-10 years (APR (CI) 1.11 [1.01,1.21]) were more likely to have gained weight excessively as compared to FB teens and FB teens that have been in the US longer than 5 years are more likely to gain weight excessively during pregnancy as compared to teens with fewer than 5 years in the US. These results identify a critical period when adolescents are in frequent contact with health care providers and can receive counseling regarding healthy weight gain.

    Research is needed to confirm that public health recommendations for home/family food environments are equally relevant for diverse populations. This study examined ethnic/racial differences in the home/family environments of adolescents and associations with dietary intake and weight status. The sample included 2374 ethnically/racially diverse adolescents and their parents enrolled in coordinated studies, EAT 2010 (Eating and Activity in Teens) and Project F-EAT (Families and Eating and Activity in Teens), in the Minneapolis/St. Paul metropolitan area. Adolescents and parents completed surveys and adolescents completed anthropometric measurements in 2009-2010. Nearly all home/family environment variables (n=7 of 8 examined) were found to vary significantly across the ethnic/racial groups. Several of the home/family food environment variables were significantly associated with one or more adolescent outcome in expected directions. For example, parental modeling of healthy food choices was inversely associated with BMI z-score (p=0.03) and positively associated with fruit/vegetable consumption (pethnic/racial groups; however; eight relationships were found to differ by ethnicity/race. For example, parental encouragement for healthy eating was associated with lower intake of sugar-sweetened beverages only among youth representing the White, African American, Asian, and mixed/other ethnic/racial groups and was unrelated to intake among East African, Hispanic, and Native American youth. Food and nutrition professionals along with other providers of health programs and services for adolescents should encourage ethnically/racially diverse parents to follow existing recommendations to promote healthy eating such as modeling nutrient-dense food choices, but also recognize the need for cultural sensitivity in providing such guidance.

    The long-term interaction between elevated CO{sub 2} and soil water deficit was analysed in N{sub 2}-fixing alfalfa plants in order to assess the possible drought tolerance effect of CO{sub 2}. Elevated CO{sub 2} could delay the onset of drought stress by decreasing transpiration rates, but this effect was avoided by subjecting plants to the same soil water content. Nodulated alfalfa plants subjected to ambient (400 {mu}mol mol{sup -1}) or elevated (700 {mu}mol mol{sup -1}) CO{sub 2} were either well watered or partially watered by restricting water to obtain 30% of the water content at field capacity (approximately 0.55 g water cm{sup -3}). The negative effects of soil water deficit on plant growth were counterbalanced by elevated CO{sub 2}. In droughted plants, elevated CO{sub 2} stimulated carbon fixation and, as a result, biomass production was even greater than in well-watered plants grown in ambient CO{sub 2}. Below-ground production was preferentially stimulated by elevated CO{sub 2} in droughted plants, increasing nodule biomass production and the availability of photosynthates to the nodules. As a result, total nitrogen content in droughted plants was higher than in well-watered plants grown in ambient CO{sub 2}. The beneficial effect of elevated CO{sub 2} was not correlated with a better plant water status. It is concluded that elevated CO{sub 2} enhances growth of droughted plants by stimulating carbon fixation, preferentially increasing the availability of photosynthates to below-ground production (roots and nodules) without improving water status. This means that elevated CO{sub 2} enhances the ability to produce more biomass in N{sub 2}-fixing alfalfa under given soil water stress, improving drought tolerance. (au)

    To describe sleep duration and sleep characteristics, and to examine the associations between sleep duration and characteristics and body weight status, diet quality, and physical activity levels among grade 5 children in Nova Scotia. A provincially representative sample of 5,560 grade 5 children and their parents in Nova Scotia was surveyed. Parents were asked to report their child's bedtime and wake-up time, and to indicate how often their child snored or felt sleepy during the day. Dietary intake and physical activity were selfreported by children using the Harvard Youth/Adolescent Food Frequency Questionnaire and the Physical Activity Questionnaire for Children respectively. Body weight status was determined using measured heights and weights. Linear and logistic random effects models with children nested within schools were used to test for associations. Approximately half of the surveyed parents reported that their children were not getting adequate sleep at night. Longer sleep duration was statistically significantly associated with decreased risk for overweight and obesity independent of other sleep characteristics (OR = 0.82, 95% CI: 0.73, 0.91). Longer sleep duration was also associated with better diet quality and higher levels of physical activity. These findings indicate a need for health promotion strategies to encourage adequate sleep and to promote healthy sleep environments among children. Given the links among sleep, body weight status and lifestyle behaviours, these messages should be included in public health interventions aimed at preventing obesity and promoting health among children.

High serum γ-carboxylated OC reflects a high, and high uncarboxylated OC (ucOC) reflects a low vitamin K status. A revolutionary hypothesis is that ucOC acts as a hormone improving glucose handling and reducing fat mass. The objective was to test the logical extrapolation of the ucOC hormone hypothesis to humans that elevated ucOC is associated with higher body weight, BMI and fat mass. In a cross-sectional analysis, the associations of vitamin K status with circulating adiponectin and body composition were investigated in 244 postmenopausal women (study I). The effects of vitamin K treatment on adiponectin, body weight and BMI were investigated in archived samples from forty-two young men and women who received varying doses of menaquinone-7 during 12 weeks (study II) and from a cohort of 164 postmenopausal women who participated in a 3-year placebo-controlled trial on 45 mg menaquinone-4 (MK-4) (study III). No association was found between vitamin K status and circulating adiponectin before or after vitamin K supplementation. A higher carboxylation of OC was significantly correlated with lower body weight, BMI and fat mass of the trunk. Women taking MK-4 maintained their baseline body weight and BMI, whereas women taking placebo showed significant increases in both indices. These findings demonstrate that a high vitamin K status of bone has no effect on circulating adiponectin in healthy people and long-term vitamin K supplementation does not increase weight in healthy postmenopausal women.

    To test for differential weight loss response to low-fat (LF) vs. low-carbohydrate (LC) diets by insulin resistance status with emphasis on overall quality of both diets. Sixty-one adults, BMI 28-40 kg/m(2) , were randomized in a 2 × 2 design to LF or LC by insulin resistance status in this pilot study. Primary outcome was 6-month weight change. Participants were characterized as more insulin resistant (IR) or more insulin sensitive (IS) by median split of baseline insulin-area-under-the-curve from an oral glucose tolerance test. Intervention consisted of 14 one-hour class-based educational sessions. Baseline % carbohydrate:% fat:% protein was 44:38:18. At 6 months, the LF group reported 57:21:22 and the LC group reported 22:53:25 (IR and IS combined). Six-month weight loss (kg) was 7.4 ± 6.0 (LF-IR), 10.4 ± 7.8 (LF-IS), 9.6 ± 6.6 (LC-IR), and 8.6 ± 5.6 (LC-IS). No significant main effects were detected for weight loss by diet group or IR status; there was no significant diet × IR interaction. Significant differences in several secondary outcomes were observed. Substantial weight loss was achieved overall, but a significant diet × IR status interaction was not observed. Opportunity to detect differential response may have been limited by the focus on high diet quality for both diet groups and sample size. © 2015 The Obesity Society.

    Small scale distribution of insect root herbivores may promote plant species diversity by creating patches of different herbivore pressure. However, determinants of small scale distribution of insect root herbivores, and impact of land use intensity on their small scale distribution are largely unknown. We sampled insect root herbivores and measured vegetation parameters and soil water content along transects in grasslands of different management intensity in three regions in Germany. We calc...

    Suboptimal weight loss (SWL) and weight regain (WR) after gastric bypass surgery (GB) remains poorly understood. This study aims to compare GB patients experiencing SWL or significant WR (SigWR) with successful controls, regarding postoperative food intake, eating behavior, physical activity (PA), and psychometrics. Forty-nine patients with >1 year post-surgery were classified as either experiencing SWL (excess body weight loss, EWL, weight regain ≥15%, n = 38), with respective control groups. Energy intake (EI) was measured with a Food Frequency Questionnaire, eating behavior using the Dutch Eating Behavior Questionnaire and the Three-Factor Eating Questionnaire, and PA using both SenseWear Armbands and the International Physical Activity Questionnaire. Eating disorders, depression, and quality of life (QoL) were measured using the Eating Disorder Examination Questionnaire, Beck Depression Inventory II, and Impact of Weight on Quality of Life, respectively. EI, macronutrient distribution, and meal frequency were similar among groups. However, disinhibited eating behavior score was h
