    This two-volume set focuses on the interface between physiologic mechanisms and diagnostic human engineering. Today numerous biomedical sensors are commonplace in clinical practice. The registered biosignals reflect mostly vital physiologic phenomena. In order to adequately apply biomedical sensors and reasonably interpret the corresponding biosignals, a proper understanding of the involved physiologic phenomena, their influence on the registered biosignals, and the technology behind the sensors is necessary. The first volume is devoted to the interface between physiologic mechanisms and arising biosignals, whereas the second volume is focussed on the interface between biosignals and biomedical sensors. The physiologic mechanisms behind the biosignals are described from the basic cellular level up to their advanced mutual coordination level during sleep. The arising biosignals are discussed within the scope of vital physiologic phenomena to foster their understanding and comprehensive analysis.

    Full Text Available Multiple psychosocial problems and many chronic diseases of adulthood can be influenced by adolescent nutritional problems. In Korea, adolescent obesity and obesity related health risks have been increased and insufficient intakes of nutrients, such as calcium, iron and potassium, and distorted thinking about obesity are also common. However there are no comprehensive countermeasure because of the excessive burden of studies and the lack of community interest. And the nutrition guidelines that is suitable for Korean adolescent leaves something to be desired, and the pediatrician’s concern is lacking yet. In the Korean dietary reference intakes 2010 that was revised according to the 2007 Korean National Growth Chart and 2007 Korean National Health and Nutrition Examination Survey, the range for adolescents is changed to the age 12-18 and dietary reference intakes of some nutrients mainly with vitamin D is changed. Recently several researches, about how school nutrition policies and media effect on eating habits and the weight concerns, and influences of public nutrition policies and fast food commercials have been actively studied to improve adolescent nutritive conditions. In this review, I summarize the dietary reference intakes for Korean adolescents that were revised in 2010, and current studies about the adolescent nutrition.

Methods: Observational, cross-sectional and descriptive study conducted from August to September 2010 at a gym in Fortaleza-CE. A questionnaire comprising identification, anthropometric, dietary and supplementary data was applied to the adolescents. Data was analyzed using the Avanutri software, which assessed the adolescents’ nutritional status and the macronutrients and micronutrients caloric intake. Results: The sample consisted of 33 students, of which 66.7% (n=22 were male and 33.3% (n=11 female. It is noteworthy that the majority of boys (60.6%; n=20 and of girls (27.3%; n=9 presented adequate Body Mass Index (BMI. As for the caloric intake, insufficient consumption predominated (39.4%; n=13 among boys. Regarding macronutrients, insufficient consumption of carbohydrates predominated in both sexes. The protein intake was adequate in most of the group and the predominant fat intake was excessive. On the micronutrients, there was great inadequacy, especially the intake of calcium, vitamins A, B2 and B6, zinc, magnesium and copper. Vitamin E, niacin and pyridoxine were being consumed in amounts potentially harmful. Conclusion: Although the majority of adolescents have shown normal nutritional status, the analyzed questionnaires showed a large inadequacy, which is liable, in the long term, to affect health. doi:http://dx.doi.org/10.5020/18061230.2013.p489

Nevertheless, recent applications of modeling have been instrumental in answering important nutritional questions from the cellular up to the physiological levels. Capturing the complexity of today's important nutritional research questions poses a challenge for modeling to become truly integrative in the consideration and interpretation of experimental data at widely differing scales of space and time. In this review, we discuss a selection of available modeling approaches and applications relevant for nutrition. We then put these models into perspective by categorizing them according to their space and time domain. Through this categorization process, we identified a dearth of models that consider processes occurring between the microscopic and macroscopic scale. We propose a “middle-out” strategy to develop the required full-scale, multilevel computational models. Exhaustive and accurate phenotyping, the use of the virtual patient concept, and the development of biomarkers from “-omics” signatures are identified as key elements of a successful systems biology modeling approach in nutrition research—one that integrates physiological mechanisms and data at multiple space and time scales.

    Full Text Available OBJECTIVE: To perform a sistematiy review of the literature about the nutritional impact of inflammatory bowel diseases in children and adolescents.DATA SOURCES: A systematic review was performed using PubMed/MEDLINE, LILACS and SciELO databases, with inclusion of articles in Portuguese and in English with original data, that analyzed nutritional aspects of inflammatory bowel diseases in children and adolescents. The initial search used the terms "inflammatory bowel diseases" and "children" or "adolescents" and "nutritional evaluation" or "nutrition deficiency". The selection of studies was initially performed by reading the titles and abstracts. Review studies and those withouth data for pediatric patients were excluded. Subsequently, the full reading of the articles considered relevant was performed.RESULTS: 237 studies were identified, and 12 of them were selected according to the inclusion criteria. None of them was performed in South America. During the analysis of the studies, it was observed that nutritional characteristics of patients with inflammatory bowel disease may be altered; the main reports were related to malnutrition, growth stunting, delayed puberty and vitamin D deficiency.CONCLUSION: There are nutritional consequences of inflammatory bowel diseases in children and adolescents, mainly growth stunting, slower pubertal development, underweight and vitamin deficiencies. Nutritional impairments were more significant in patients with Crohn's disease; overweight and obesity were more common in patients with ulcerative rectocolitis. A detailed nutritional assessment should be performed periodically in children and adolescents with inflammatory bowel disease.

  15. Safeguarding nutritional status of adolescent mothers

    International Nuclear Information System (INIS)

    The Baby-Friendly Hospital Initiative (BFHI) has been introduced in Mexico in order to increase breast feeding. The Mexican health care system may be contributing negatively to the nutritional status of adolescent mothers and their infants due to the reduction of baby formulas which were previously supplied as a benefit. The aim of this study is to evaluate breast-milk production, the quantity and quality of protein and changes in body composition in adolescent and adult mothers in order to design the right ways to help mother and infants fulfill their requirements or obtain support to apply to the BFHI program. We propose to measure breast-milk intake and total body water by deuterium kinetics using infrared spectroscopy. Protein concentration and composition will be measured by electrophoresis. Adolescent and adult mothers who are breast-feeding exclusively and living in two different urban regions, northwest and central Mexico, will be dosed with deuterium oxide; saliva and breast milk samples will be taken. Currently, both of the working groups are standardized. A sublimation system for separation of water and D2O of the saliva samples under reduced pressure was designed and it has a 100% of D2O recovery. The setting up of conditions for D2O determination using infrared spectroscopy was achieved and calibration curves of absorbance of sequentially diluted D2O were obtained with an r=0.9948. Total body water was measured in 12 women after 1, 3, 6, 9 and 14 days of the D2O dose. Zero-time values obtained by extrapolation were similar to those directly obtained after 4 h equilibrium. In addition, 50 women (under inclusion criteria) have signed consent letters to participate and part of the study is currently underway. For 1998, we intend to have 40 women and their infants with both dosing periods analyzed, as well as the analysis of breast milk composition. (author)

    2015-07-01

    Full Text Available In modern science, along with the “classic” and “non-classical” approach to solving fundamental and applied problems, there is an actively developing “postnonclassical” research paradigm. This renovation of general scientific methodology has been accompanied by the emergence of new experimental technologies and new scientific research directions based on them. “Social psychophysiology” is one such direction. It is formed within the frame of postnonclassical methodology at the intersection of neuroscience and psychology. This work is devoted to the analytical review of the methods, achievements and prospects of contemporary social neuroscience and social psychophysiology studying brain structures that are specifically related to the implementation of social forms of behavior and intercultural communication. Physiological studies of brain activity during social interaction processes, which are simulated using virtual reality environments, are analyzed, and the physiological approach to the study of the brain mechanisms associated with social perception, social cognition and social behavior is used. Along with the analysis of psychophysiological studies of the mechanisms of social perception and social cognition, we discuss the theories of “Brain Reading” and “Theory of Mind” and the underlying data concerning “Gnostic neurons recognition of persons and recognition of emotional facial expressions”, “mirror neurons”, “emotional resonance” and “cognitive resonance”. Particular emphasis is placed on the discussion of a fundamentally new trend in the study of the relationship between the brain and culture (i.e., “cultural neuroscience”. Related to this connection, the following topics are raised: physiological mechanisms protecting the “individual distance” in communication between members of a personified community, psychophysiological approaches to the study of cross-cultural differences, physiological

    Adolescents' body image (BI) may not match their nutritional status. This study selected representative sample of healthy adolescents aged between 12 and 18 from public and private schools. Anthropometric measures were performed in order to calculate the body mass index (BMI) percentile. The silhouette scale proposed by Childress was used to evaluate BI, making it possible to assess BI satisfaction and BI distortion. The sample was composed of 1168 adolescents with a mean age of 14.7 years; 52.9% were female, 50.9% were fair-skinned, 62.4% had consumed or still consume alcohol and 67% attended public school. Male adolescents presented more overweight and obesity (28.4%) (pbody weight and 82.5% of those underweight wished to gain body weight. BI distortion was identified, since 35% of the adolescents who were underweight did not regard themselves thin, 39.1% of the overweight individuals and 62.1% of the obese did not see themselves in their adequate classifications. Adolescents with overweight/obesity were those who presented higher dissatisfaction with BI, mainly the females. Male individuals presented a greater wish of gaining weight. BI distortion was present in adolescents of all classes of BMI percentile. PMID:25064308

Changes in dietary habits may induce different types of nutritional disorders and are likely to track into adulthood. The aim of this review is to describe the key findings related to nutritional status in European adolescents participating in the HELENA (Healthy Lifestyle in Europe by Nutrition in Adolescence) study. We performed a cross-sectional study in 3528 (1845 females) adolescents aged 12.5–17.5 y. Birth weight was negatively associated with abdominal fat mass in adolescents and serum leptin concentrations (in female adolescents), providing additional evidence for a programming effect of birth weight on energy homeostasis control. Breakfast consumption was associated with lower body fat content and healthier cardiovascular profile. Adolescents eat half of the recommended amount of fruit and vegetables and less than two-thirds of the recommended amount of milk and milk products but consume more meat and meat products, fats, and sweets than recommended. For beverage consumption, sugar-sweetened beverages, sweetened milk, low-fat milk, and fruit juice provided the highest amount of energy. Although the intakes of saturated fatty acids (FAs) and salt were high, the intake of polyunsaturated FAs was low. Adolescents spent, on average, 9 h/d of their waking time (66–71% and 70–73% of the registered time in boys and girls, respectively) in sedentary activities. Factors associated with adolescents’ sedentary behavior included the following: 1) age; 2) media availability in the bedroom; 3) sleeping time; 4) breakfast consumption; and 5) season. Sedentary time was also associated with cardiovascular risk factors and bone mineral content. In European adolescents, deficient concentrations were identified for plasma folate (15%), vitamin D (15%), pyridoxal 5′-phosphate (5%), β-carotene (25%), and vitamin E (5%). Scientists and public

    This study aimed to examine school principals' perceptions of the school environment in Hong Kong as a context for the dissemination of food knowledge and inculcation of healthy eating habits. A questionnaire survey was administered in secondary schools in Hong Kong to survey Principals' views of students' food choices, operation of the school tuck shop, and promotion of healthy eating at school. Questionnaires were disseminated to all the secondary schools offering Home Economics (300 out of 466), and 188 schools responded, making up a response rate of 63%. Collected data were analyzed using SPSS. Most of the schools (82%) claimed to have a food policy to monitor the operation of the school canteen, and about half (52%) asserted there were insufficient resources to promote healthy eating at school. Principals (88%) generally considered it not acceptable for the school tuck shop to sell junk food; however, 45% thought that banning junk food at school would not help students develop good eating habits. Only 4% of the principals believed nutrition education influenced eating habits; whereas the majority (94%) felt that even with acquisition of food knowledge, students may not be able to put theory into practice. Cooking skills were considered important but principals (92%) considered transmission of cooking skills the responsibility of the students' families. Most of the principals (94%) believed that school-family collaboration is important in promoting healthy eating. Further efforts should be made to enhance the effectiveness of school food policies and to construct healthy school environments in secondary schools. PMID:21393115

    Malnutrition, either by insufficient supply of some nutrients or by overfeeding has a profound effect on the health of an organism. Therefore, optimal nutrition is mandatory on Earth (1 g), in microgravity and also when applying artificial gravity to the human system. Immobilization like in microgravity or bed rest also has a profound effect on different physiological systems, like body fluid regulation, the cardiovascular, the musculoskeletal, the immunological system and others. Up to now there is no countermeasure available which is effective to counteract cardiovascular deconditioning (rf. Chapter 5) together with maintenance of the musculoskeletal system in a rather short period of time. Gravity seems therefore to be one of the main stimuli to keep these systems and application of certain duration of artificial gravity per day by centrifugation has often been proposed as a very potential countermeasure against the weakening of the physiological systems. Up to now, neither optimal intensity nor optimal length of application of artificial gravity has been studied sufficiently to recommend a certain, effective and efficient protocol. However, as shown in chapter 5 on cardiovascular system, in chapter 6 on the neuromuscular system and chapter 7 (bone and connective system) artificial gravity has a very high potential to counteract any degradation caused by immobilization. But, nutrient supply -which ideally should match the actual needs- will interact with these changes and therefore has also to be taken into account. It is well known that astronauts beside the Skylab missions- were and are still not optimally nourished during their stay in space (Bourland et al. 2000;Heer et al. 1995;Heer et al. 2000b;Smith et al. 1997;Smith & Lane 1999;Smith et al. 2001;Smith et al. 2005). It has also been described anecdotally that astronauts have lower appetites. One possible explanation could be altered taste and smell sensations during space flight, although in some early

    Browning phenomena are ubiquitous in plant cell cultures that severely hamper scientific research and widespread application of plant cell cultures. Up to now, this problem still has not been well controlled due to the unclear browning mechanisms in plant cell cultures. In this paper, the mechanisms were investigated using two typical materials with severe browning phenomena, Taxus chinensis and Glycyrrhiza inflata cells. Our results illustrated that the browning is attributed to a physiological enzymatic reaction, and phenolic biosynthesis regulated by sugar plays a decisive role in the browning. Furthermore, to confirm the specific compounds which participate in the enzymatic browning reaction, transcriptional profile and metabolites of T. chinensis cells, and UV scanning and high-performance liquid chromatography-mass spectrometry (HPLC-MS) profile of the browning compounds extracted from the brown-turned medium were analyzed, flavonoids derived from phenylpropanoid pathway were found to be the main compounds, and myricetin and quercetin were deduced to be the main substrates of the browning reaction. Inhibition of flavonoid biosynthesis can prevent the browning occurrence, and the browning is effectively controlled via blocking flavonoid biosynthesis by gibberellic acid (GA3 ) as an inhibitor, which further confirms that flavonoids mainly contribute to the browning. On the basis above, a model elucidating enzymatic browning mechanisms in plant cell cultures was put forward, and effective control approaches were presented. PMID:26333689

    During 1990-1993, 83,000 ethnic Nepalese fled from Bhutan to refugee camps in southeast Nepal after new citizenship policies were enacted by the Bhutanese government. Although annual nutrition surveys of children aged refugees arrived in 1990. After withdrawal of a fortified cereal from their rations, the number of reported cases of angular stomatitis (AS) (i.e., thinning and/or fissuring at the angles of the mouth, a sign of possible vitamin deficiency) increased six-fold during December 1998-March 1999 (from 5.5 to 35.6 cases per 1000 refugees) (Santa Tamang, MD, Save the Children Fund, United Kingdom, personal communication, 1999). The highest rates of AS were found among children and adolescents. In October 1999, CDC was invited by the World Food Programme and the United Nations High Commissioner for Refugees to assess the health status of adolescent refugees. This report summarizes the investigation, which indicated a high prevalence of low body mass index (BMI), anemia, low vitamin A status, and signs of micronutrient deficiencies among adolescent refugees.

    ObjectiveTo study the nutrition habits among Chinese-Korean children and adolescents in Yanbian Autonomous Prefecture, Jilin, China. MethodsData were obtained from the Chinese National Survey on Students’ Constitution and Health in 1995, 2000, 2005, and 2010 for Chinese-Korean children and adolescents aged 7-18 years.The number of the subjects included was 4789, 4704, 5875, and 5315, respectively. ResultsThe rate of the occurrence of stunting showed a declining trend from 1995 to 2010 (for boys:urban, 6.3%; rural, 12.7% in 1995 and 3.5% for both in 2010. For girls: urban, 7.8%; rural, 13.4% in 1995 and 4.2% and 5.5%, respectively, in 2010). Although the ratio of wasting did not show significant differences between the urban and rural children and adolescents in 1995, 2000, 2005, and 2010 respectively, the ratio of occurrence of overweight or obesity increased (for boys: urban, 7.3% and 1.3%in 1995, 17.6% and 12.9% in 2010; rural, 7.0% and 1.3% in 1995, 14.6% and 12.8% in 2010, respectively. For girls: urban, 8.1% and 1.0% in 1995, 17.3% and 8.6% in 2010; rural 5.7% and 0.7% in 1995, 16.4%and 7.4% in 2010, respectively). ConclusionThe ratio of malnutrition in children and adolescents in Chinese-Korean areas declined from 1995 to 2010, and the distinction in malnutrition between the urban and rural areas was negligible in 2010. Further, the ratio of overweight and obesity increased over this period.

    The objective of this research was to assess adherence to the Healthy Eating Index-2010 of mothers and their adolescents (11-14 years old) and to examine the role of the home environment as a mediator of maternal nutrition knowledge and adolescent diet quality. It is hypothesized that mothers with greater knowledge impact the diet quality of their adolescents by creation of healthier home environments. A sample of 206 mother-adolescent dyads separately completed the Multidimensional Home Environment Scale, a Food Frequency Questionnaire, and a Nutrition Knowledge Scale. Body mass index-for-age percentiles were derived from weight and height measurements obtained by researcher; diet quality was estimated via the Healthy Eating Index (HEI)-2010. Percent of maximum score on nutrition knowledge for both mothers and adolescents were poor, with lowest scores on recommendations of healthy eating and physical activity (48% and 19%, respectively). A model of maternal nutrition knowledge (independent variable) and adolescent diet quality (dependent variable) indicated that greater knowledge was associated with higher scores on total fruit (p = 0.02), whole grains (p = 0.05), seafood and plant proteins (p = 0.01), and overall diet quality (p variables were all significant mediators of nutrition knowledge on diet quality. These results emphasize the importance of maternal nutrition knowledge and the mediating effect of the home environment on the diet quality of adolescents. PMID:27170447

    The current study examined mean level and change in extraversion and neuroticism across adolescence in relation to physiological stress reactivity to social evaluation. Adolescents (n=327) from the Dutch general population reported on personality measures at five annual assessments. At age 17 years, adolescents participated in a psychosocial stress procedure characterized by social evaluation during which cortisol, heart rate, pre-ejection period (PEP) and heart rate variability were assessed. Dual latent growth curve models were fitted in which the intercepts (mean level) and slopes (change) of personality across adolescence predicted the intercepts (baseline) and slopes (reactivity) of the physiological stress measures. Most comparisons revealed no relation between personality and stress reactivity. Adolescents with higher mean level scores on extraversion did show lower cortisol reactivity. Adolescents with higher mean level neuroticism scores showed higher PEP reactivity. Our findings lend partial support for a relation between personality and physiological stress reactivity.

    Few gastrointestinal functions decline to an important extent as a result of old age alone and there is little clinical evidence that significant malnutrition occurs in any normal elderly person as a result of the aging process itself. Nevertheless, decreased gastrointestinal reserve makes older people highly sensitive to minor insults and decompensation can rapidly occur. Drugs appreciably affect taste sensation, which is already blunted and psychological as well as physical disability can have a major impact on appetite. Malabsorption can be caused by gastric hypochlorhydria with small bowel bacterial overgrowth and while gastrointestinal dysmotility can be caused by subclinical hypothyroidism, it can improve in response to physical exercise. Evidence is now mounting that thorough investigation of gastrointestinal disturbances in elderly patients coupled with intensive nutritional support can make a very real impact on their outcome. Gastroenterologists should therefore seek out and actively treat gastrointestinal disorders in the elderly and not just ascribe them to old age. PMID:8675079

    Background Anorexia nervosa (AN) is prevalent in adolescents and is associated with decreased bone mineral accrual at a time critical for optimizing bone mass. Low bone mineral density (BMD) in AN is a consequence of nutritional and hormonal alterations, including hypogonadism and low estradiol levels. Effective therapeutic strategies to improve BMD in adolescents with AN have not been identified. Specifically, high estrogen doses given as an oral contraceptive do not improve BMD. The impact of physiological estrogen doses that mimic puberty on BMD has not been examined. Subjects and Methods We enrolled 110 girls with AN and 40 normal-weight controls (C) 12–18y of similar maturity. Subjects were studied for 18 months. Mature AN [bone age (BA) ≥15 y; n=96] were randomized to transdermal 100mcg 17β-estradiol (with cyclic progesterone) or placebo for 18m. Immature AN (BA <15y; n=14) were randomized to incremental low dose oral ethinyl-estradiol (3.75mcg daily from 0–6m, 7.5mcg from 6–12m, 11.25mcg from 12–18m) to mimic pubertal estrogen increases, or placebo for the 18m duration. Results All BMD measures assessed by dual energy x-ray absorptiometry (DXA) were lower in AN than C. At baseline, AN randomized to estrogen (AN E+) did not differ from those randomized to placebo (AN E−) for age, maturity, height, BMI, amenorrhea duration and BMD parameters. Spine and hip BMD Z-scores increased over time in the AN E+ compared with AN E− group, even after controlling for baseline age and weight. Conclusion Physiological estradiol replacement increases spine and hip BMD in girls with AN. PMID:21698665

    Space flight provides a model for the study of healthy individuals undergoing unique stresses. This review focuses on how physiological adaptations to weightlessness may affect nutrient and food requirements in space. These adaptations include reductions in body water and plasma volume, which affect the renal and cardiovascular systems and thereby fluid and electrolyte requirements. Changes in muscle mass and function may affect requirements for energy, protein and amino acids. Changes in bone mass lead to increased urinary calcium concentrations, which may increase the risk of forming renal stones. Space motion sickness may influence putative changes in gastro-intestinal-hepatic function; neurosensory alterations may affect smell and taste. Some or all of these effects may be ameliorated through the use of specially designed dietary countermeasures.

    Groth, Susan W; Morrison-Beedy, Dianne

    2011-01-01

    Obesity is an expanding epidemic and minority adolescent girls are at high risk. One way to tailor interventions for obesity prevention is to target intention to engage in particular behaviors. Data collected from adolescent girls' intentions and behaviors regarding nutrition, physical activity, and sleep patterns were used to examine nutritional intentions in relation to healthy behaviors. Adolescent girls reported behaviors that increased their risks for obesity. Nutritional intentions were significantly associated with physical activity and sleep. These results suggest that healthy behaviors tend to occur in clusters, possibly extending the theory of planned behavior beyond individual behaviors to groups of related behaviors. Nurses can intervene with high-risk adolescent girls by promoting healthy diets, recommended levels of physical activity, and adequate sleep. PMID:22187861

    Full Text Available ABSTRACT: Bullying is a devastating phenomenon that can affect the adolescent’s self-esteem and mental health. Generally occurs in school environment when the adolescent is more susceptible or vulnerable to verbal or moral aggressions that cause to them anguish and pain, meaning as a status of social exclusion. Most of time, health problems as anorexia, bulimia, depression, anxiety and also the suicide, appears. By the way, nurses are able to prevent injuries to various problems, and also concerns about this traumatic incident in adolescence. The aim of this study was to identify feelings that can be related to” bullying “in adolescent students in 5th to 8th classes. It is a descriptive research by qualitative approach, developed in a religious setting state school. Data was collected by taped interviews and, after transcribed, submitted to thematic analysis. The results showed that feelings related to this phenomena are multiple and varied, being categorized as positive aspects character, negative aspects character and necessary aspects character.

    Our understanding of how food modulates animal phenotypes and mediate trade-offs between life-history traits has benefited greatly from the study of combinations of nutritional and non-nutritional food components, such as plant secondary metabolites. We used a fruit fly pest, Anastrepha ludens, to examine phenotypic variation across larval, pupal and adult stages as a function of larval food with varying nutrient balance and content of chlorogenic acid, a secondary metabolite. Larval insects that fed on carbohydrate-biased diets relative to protein exhibited longer larval and pupal developmental periods, were often heavier as pupae and resisted desiccation and starvation for longer periods in the adult stage than insects fed on highly protein-biased diets. Except for a potential conflict between pupal development time and adult desiccation and starvation resistance, we did not detect physiological trade-offs mediated by the nutritional balance in larval food. Chlorogenic acid affected A. ludens development in a concentration and nutrient-dependent manner. Nutrients and host plant secondary metabolites in the larval diet induced changes in A. ludens phenotype and could influence fruit fly ecological interactions. We provide a unique experimental and modelling approach useful in generating predictive models of life history traits in a variety of organisms. PMID:27406923

    Full Text Available Background/Aim. Proper nutrition and regular physical activity are essential parts of a adolescent's overall health. The aim of this research was to evaluated eating and physical activity behaviours and habits, nutritional and food knowledge, beliefs and self-efficacy related to diet and health of the adolescents of the city of Belgrade, Serbia. Methods. A dietary questionnaire previously constructed and tested in adolescent population from Italy was self-administrated. We evaluated eating habits, physical activity, meaning of healthy and unhealthy dietary habits and food, self-efficacy, barriers affecting food choices, nutritional and food safety, and body mass index (BMI of the adolescents. The sample included 707 adolescents, the mean age of 15,8 ± 2 years enrolled in the first grade at several high schools in Belgrade. Results. Only 27% of the adolescents had satisfactory eating habits; 31% have a very active lifestyle; 7% good nutritional knowledge and 6- 12% satisfactory food safety knowledge and hygiene practices. Conclusion. Significant deviations from recommendations for healthy lifestyle was noted in adolescents’ habits, knowledge and practice. It is therefore necessary to develop and organize programs for promotion of healthy behaviours adapted to the adolescents’ needs. [Projekat Ministarstva nauke Republike Srbije, br. III47015

    Adolescents in Busan area were asked in a survey about their perception and attitudes towards fast food. Most respondents answered that they consume fast food once a month because it is fast, easily accessible and tasty. Although they perceived fast food as unhealthy and less nutritious, they were less aware of its effect on their health and nutritional status. The more knowledgeable respondents were about nutrition and health the less likely they were to choose fast food over other meals. Ho...

    Full Text Available : Adolescence is a time when the body prepares itself for the nutritional demands of pregnancy, lactation and heavy workloads that girls will soon experience. Good nutrition is essential for good health, physical growth and development, body composition and mental development In recent years, the incidence of adolescent pregnancy and childbirth is increasing due to the early onset of puberty, the declining age of menarche and early sexual activity. They need to earn to cope with the future demands of life. Nutritional needs during adolescence are increased because of the increased growth rate and changes in the body composition associated with puberty. The dramatic increase in energy and nutrient requirements coincides with other factors that may affect adolescents’ food choices and nutrient intake and thus nutritional status. National and population based surveys have found that adolescents often fail to meet dietary recommendations for over all nutritional status and for specific nutrient intakes. Nutritional requirements in relation to body size are more during adolescence. In a country like India with varying social customs and common beliefs against females there is a high prevalence of malnutrition amongst girls. Adolescents are tomorrow’s adult population and their health and well-being are crucial. Yet, interest in adolescents’ health is relatively recent and a focus on nutrition is even more recent. Nutrition influences growth and development throughout infancy, childhood and adolescence; it is, however, during the period of adolescence that nutrient needs are the greatest. A questionnaire-based study was undertaken in Jaipur city of Rajasthan with 500 respondents divided equally between government schools and private schools populations. Adolescent girl is subjected to more physical and mental challenges on a day –to-day basis due to ever increasing pressure of modernization. Hence they have to work hard physically as well as

    Full Text Available ABSTRACT Objective: To evaluate changes in food intake after adolescents attended a food and nutrition education program at a non-profit institution. Methods: Fifty-four adolescents aged 16 to 19 years, of low socioeconomic level, enrolled in an non-governmental organization in São Paulo, underwent a nutritional intervention of six months consisting of six meetings with dieticians, as well as strategic communication and relationship actions. Body weight, height, body mass index, questionnaire on knowledge on nutrition and feeding practices, 24-hour recall, and diet quality assessment using the Diet Quality Index associated with the Digital Food Guide were collected at baseline and after the intervention. Dietary pattern improvement was defined as an increase of at least 5 points in Diet Quality Index associated with the Digital Food Guide. Results: Understanding of food labels increased, and the dietary patterns on weekdays and weekends improved by 33 and 37%, respectively. The intake of legumes, milk, dairy products, fruits, and vegetables increased (adequacy components. However, intakes of nuts and whole grains were low, and intake of moderation components was high. Conclusion: The program improved the dietary patterns of adolescents, making it a viable and inexpensive method to prevent disease and improve health and quality of life. In addition, the Diet Quality Index associated with the Digital Food Guide has proven to be a good nutritional tool for assessing changes in food intake and for guiding future counseling and nutritional intervention actions for this population.

    Full Text Available BACKGROUND: Adolescence is the formative period of life when the maximum amount of physical, psychological and behavioral changes takes place and this is a vulnerable period in the human life cycle for the development of nutritional anaemia, which has been constantly neglected by public health programs. The prevalence of anaemia is disproportionately high in developing countries than developed countries. It has mainly been ascribed to poverty, inadequate diet, certain diseases, pregnancy and lactation, and poor access to health services in developing countries Prevalence of anaemia in adolescents in India have been reported in limited studies available from 16.25% to 96.5%. Nutritional anaemia constitutes the most important cause of anaemia in adolescents. It is mainly due to deficiency of Iron, Vitamin B12 and Folate. Megaloblastic Anaemia resulting from deficiency of folate and B12 appears to be increasing over the last two decades. AIMS AND OBJECTIVES: 1.To study the types of nutritional anemia in adolescents (10-18 yrs. attending the hospital and correlate severity of nutritional anemia with serum levels of ferritin, Vit B12 & folate. 2. And also to determine demographic, socio-economic & nutritional factors for nutritional anemia in adolescents. STUDY DESIGN: A cross sectional study was conducted in selected sample of 200 subjects. SETTINGS: The study was conducted in the Department of General Medicine, Azeezia Medical College; during November 2011 to April 2013, as a cross-sectional observational study. MATERIALS AND METHODS: Subjects were selected based on the inclusion criteria set and evaluated with aid of laboratory investigation of blood samples collected from subjects. RESULTS AND CONCLUSION: Present study was undertaken to find out etiology and socio-demographic correlates of nutritional anaemia in adolescents. And it was found out that Folate deficiency was the most common followed by Vitamin B12 deficiency & then irons deficiency

    It is the position of Sports Dietitians Australia (SDA) that adolescent athletes have unique nutritional requirements as a consequence of undertaking daily training and competition in addition to the demands of growth and development. As such, SDA established an expert multidisciplinary panel to undertake an independent review of the relevant scientific evidence and consulted with its professional members to develop sports nutrition recommendations for active and competitive adolescent athletes. The position of SDA is that dietary education and recommendations for these adolescent athletes should reinforce eating for long term health. More specifically, the adolescent athlete should be encouraged to moderate eating patterns to reflect daily exercise demands and provide a regular spread of high quality carbohydrate and protein sources over the day, especially in the period immediately after training. SDA recommends that consideration also be given to the dietary calcium, Vitamin D and iron intake of adolescent athletes due to the elevated risk of deficiency of these nutrients. To maintain optimal hydration, adolescent athletes should have access to fluids that are clean, cool and supplied in sufficient quantities before, during and after participation in sport. Finally, it is the position of SDA that nutrient needs should be met by core foods rather than supplements, as the recommendation of dietary supplements to developing athletes over-emphasizes their ability to manipulate performance in comparison with other training and dietary strategies.

    The present review examines the pig as a model for physiological studies in human subjects related to nutrient sensing, appetite regulation, gut barrier function, intestinal microbiota and nutritional neuroscience. The nutrient-sensing mechanisms regarding acids (sour), carbohydrates (sweet), glutamic acid (umami) and fatty acids are conserved between humans and pigs. In contrast, pigs show limited perception of high-intensity sweeteners and NaCl and sense a wider array of amino acids than humans. Differences on bitter taste may reflect the adaptation to ecosystems. In relation to appetite regulation, plasma concentrations of cholecystokinin and glucagon-like peptide-1 are similar in pigs and humans, while peptide YY in pigs is ten to twenty times higher and ghrelin two to five times lower than in humans. Pigs are an excellent model for human studies for vagal nerve function related to the hormonal regulation of food intake. Similarly, the study of gut barrier functions reveals conserved defence mechanisms between the two species particularly in functional permeability. However, human data are scant for some of the defence systems and nutritional programming. The pig model has been valuable for studying the changes in human microbiota following nutritional interventions. In particular, the use of human flora-associated pigs is a useful model for infants, but the long-term stability of the implanted human microbiota in pigs remains to be investigated. The similarity of the pig and human brain anatomy and development is paradigmatic. Brain explorations and therapies described in pig, when compared with available human data, highlight their value in nutritional neuroscience, particularly regarding functional neuroimaging techniques.

    Full Text Available INTRODUCTION: Brazil has been called a nation in nutrition transitional because of recent increases in the prevalence of obesity and related chronic diseases. With overweight conditions already prevalent among middle-income populations, there exists a need to identify factors that influence nutrition behavior within this group. OBJECTIVE: To address this subject, a research study was implemented among middle-class adolescents attending a large private secondary school in Manaus, Amazonas, Brazil. The study determined the availability and accessibility of snack foods as well as subjects' attitudes and preferences towards, and the influence of family and friends on healthy (high-nutrient density snack choices. METHODS: The 4-stage process included: (a a nutrition expert focus group discussion that reported local nutrition problems in general and factors related to adolescent nutrition, (b an adolescent pilot survey (n=63 that solicited information about snacking preferences and habits as well as resources for nutrition information and snack money; (c a survey of various area food market sources to determine the availability and accessibility of high nutrient density snacks; and (d a follow-up adolescent survey (n=55 that measured snack food preferences and perceptions about their cost and availability. RESULTS: Results included the finding that, although affordable high nutrient density snacks were available, preferences for low nutrient density snacks prevailed. The adolescents were reportedly more likely to be influenced by and obtain nutrition information from family members than friends. CONCLUSION: From study results it is apparent that a focus on food availability will not automatically result in proper nutritional practices among adolescents. This fact and the parental influence detected are evidence of a need to involve adolescents and their parents in nutrition education campaigns to improve adolescent snack food choices.

  18. A peer-based study on adolescence nutritional health: a lesson learned from Iran

    International Nuclear Information System (INIS)

    To study the adolescence opinions among nutritional habits and beliefs. Methods: To conduct a multi disciplinary approach through involving adolescence /youth for finding their mental needs and their suggestion for solving them, we designed a qualitative approach based on grounded theory. For data collection a semi-structured guide questioner designed and 16 focus group discussions were conducted by trained peers with youth aged 10-19 years. Results: According to FGDs results, although majority of participants agreed on the important role of nutrition in health and the effect of nutritional habits on different aspect of health, they used modern and publicized fast foods. On the other hand, most of female and male participants said that different factors influenced the girls and boys diet selection i. e. girls's paid more attention to diet selection and taste and health of foods, whereas boys were careless and gluttony caused more food to be consumed. Conclusion: Adolescents' information (both genders) regarding nutritional problems resulting from improper food habits were not satisfactory. Peer-based health programmes through target groups for capacity building and participation of stake holders will fulfill the objectives. (author)

    2009-01-01

    Physiological theories may be important in the development and maintenance of social phobia in youth. A limited literature base indicates that youth with social phobia experience increases in objective physiological arousal during social-evaluative situations and are more aware of such increases compared to nonanxious youth. Recent research suggests that youth with social phobia also evidence heightened levels of anxiety sensitivity, which may lead to interpretation of physiological arousal as dangerous or distressing, and, as a result, in avoidance of situations which produce increased physiological arousal. The purpose of the current study was to examine interaction among objective physiological arousal, perceived physiological arousal, and anxiety sensitivity among adolescents diagnosed with social phobia. A sample of community adolescents participated in two anxiety-provoking tasks during which objective physiological arousal was monitored, and after which perceived physiological arousal and anxiety sensitivity were evaluated. Results from this study evidenced no differences between social phobic and nonanxious adolescents with regard to objective physiological arousal during either anxiety-provoking tasks. Adolescents with social phobia, however, were more aware of measured increases in physiological arousal, as well as more afraid of the potential social implications of that arousal compared to nonanxious adolescents. Implications for theory and treatment are discussed. PMID:18436426

  6. Nutritional, physiological, physicochemical and sensory stability of gamma irradiated Kimchi (Korean fermented vegetables)

    International Nuclear Information System (INIS)

    Effects of gamma irradiation on nutritional, physiological, physicochemical and sensory properties of the Korean lactic acid fermented vegetable, Kimchi, were investigated. The composition of amino acids and organic acids in Kimchi were not influenced by gamma irradiation less than 10 kGy. Angiotensine converting enzyme inhibitory, xanthin oxidase inhibitory, electron donating and antimicrobial activity of Kimchi extract were stable up to 10 kGy. There were no significant changes in pH and texture at less than 10 kGy. Color values were influenced at 10 kGy of gamma irradiation, and resulted in the increase of L*- and reduction of a*-value. About 90% of panelists identified a sensory difference between non-irradiated and 10 kGy-irradiated sample, and Kimchi irradiated at 10 kGy had lower scores in acceptability than those of the control or irradiated at 2.5 and 5 kGy

    Full Text Available The estimate of world population growth and the extent of malnutrition problems due to lack of food or to deficit of specific micronutrients bring to light the importance of plant nutrition in the context of a sustainable development. Beside these aspects, which force to use fertilizers, the topic of nutrient use efficiency of by plants is far from being solved: recent estimates of world cereals productions indicate that use efficiency of nitrogen fertilizers is not higher than 35%. These values are even smaller for phosphorus fertilizers (estimate of use efficiency between 10 and 30%, worsen by the fact that, with the present technology and on the basis of present knowledge, it is expected that the phosphorus reserves used for fertilizer production will be sufficient for less than 100 years. Efficiency problems have also been recently raised concerning the use of synthetic chelates to alleviate deficiency of micronutrients: these compounds have been shown to be extremely mobile along soil profile and to be only partially utilizable by plants. The low uptake efficiency of nutrients from soil is, in one hand, caused by several intrinsic characteristics of the biogeochemical cycle of nutrients, by the other, seems to be limited by biochemical and physiological aspects of nutrient absorption.

    The objectives of this research were to investigate the morphological, physiological and nutritional characteristics of lettuce plants (Lactuca sativa L. cv. Rome) under hypobaric and hypoxic conditions. Plants were grown under two levels of total pressures (101 and 30 kPa) and three levels of oxygen partial pressures (21, 6 and 2 kPa) for 20 days. Hypoxia (6 or 2 kPa) not only significantly inhibited the growth of lettuce plants by decreasing biomass, leaf area, root/shoot ratio, water content, the contents of minerals and organic compounds (vitamin C, crude protein and crude fat), but also destroyed the ultrastructure of mitochondria and chloroplast. The activities of catalase and total superoxide dismutase, the contents of glutathione and the total antioxidant capacity significantly decreased due to hypoxia. Hypobaria (30 kPa) did not markedly enhance the biomass, but it increased leaf area, root/shoot ratio and relative water content. Hypobaria also decreased the contents of total phenols, malondialdehyde and total carbohydrate and protected the ultrastructure of mitochondria and chloroplast under hypoxia. Furthermore, the activities of catalase and total superoxide dismutase, the contents of minerals and organic compounds markedly increased under hypobaria. This study demonstrates that hypobaria (30 kPa) does not increase the growth of lettuce plants, but it enhances plant's stress resistance and nutritional quality under hypoxia.

  14. Winning the war against ICU-acquired weakness: new innovations in nutrition and exercise physiology.

    Wischmeyer, Paul E; San-Millan, Inigo

    2015-01-01

    Over the last 10 years we have significantly reduced hospital mortality from sepsis and critical illness. However, the evidence reveals that over the same period we have tripled the number of patients being sent to rehabilitation settings. Further, given that as many as half of the deaths in the first year following ICU admission occur post ICU discharge, it is unclear how many of these patients ever returned home. For those who do survive, the latest data indicate that 50-70% of ICU "survivors" will suffer cognitive impairment and 60-80% of "survivors" will suffer functional impairment or ICU-acquired weakness (ICU-AW). These observations demand that we as intensive care providers ask the following questions: "Are we creating survivors ... or are we creating victims?" and "Do we accomplish 'Pyrrhic Victories' in the ICU?" Interventions to address ICU-AW must have a renewed focus on optimal nutrition, anabolic/anticatabolic strategies, and in the future employ the personalized muscle and exercise evaluation techniques utilized by elite athletes to optimize performance. Specifically, strategies must include optimal protein delivery (1.2-2.0 g/kg/day), as an athlete would routinely employ. However, as is clear in elite sports performance, optimal nutrition is fundamental but alone is often not enough. We know burn patients can remain catabolic for 2 years post burn; thus, anticatabolic agents (i.e., beta-blockers) and anabolic agents (i.e., oxandrolone) will probably also be essential. In the near future, evaluation techniques such as assessing lean body mass at the bedside using ultrasound to determine nutritional status and ultrasound-measured muscle glycogen as a marker of muscle injury and recovery could be utilized to help find the transition from the acute phase of critical illness to the recovery phase. Finally, exercise physiology testing that evaluates muscle substrate utilization during exercise can be used to diagnose muscle mitochondrial dysfunction and

    This study investigated whether perceptions of parenting behaviours predict young adolescents' nutritional intake and body fatness. The randomly selected study sample consisted of 106 13-15 years olds from Houston Metropolitan Statistical Area. Parenting style variables were created by cluster analysis and factor analysis. A two-cluster solution for both maternal and paternal parenting style represented authoritative vs. non-authoritative parenting. Two parenting dimension factors derived were maternal/paternal nurturing and control. For adolescents' energy and nutrient intake, greater maternal nurturing appeared to be most beneficial given its association with lower consumption of total kilocalorie and lower saturated fat intake. Paternal nurturing was associated with lower sodium intake, whereas paternal control predicted lower percentage of kilocalories from carbohydrate and percentage Dietary Reference Intake for dietary fibre, and greater percentage of kilocalories from total fat. Maternal authoritative parenting and lower maternal control over their adolescents may have protective effects against having heavier and fatter adolescents given their associations with adolescents' body weight, sub-scapular skinfold, waist circumference, body mass index, and the tendencies of being at risk of overweight and being overweight. None of paternal parenting styles or dimensions appeared to be significantly related to adolescents' body fatness. PMID:18811793

    2013-12-01

    The objectives of this study were to examine the trend in unhealthy food intake by socioeconomic position (SEP) and to determine whether the government's nutritional policies affect socioeconomic disparity in the food intake among adolescents. Data were from the six independent cross-sectional survey data (2006-2011) of Korea Youth Risk Behavior Web-based Survey and included 445,287 subjects aged 12-18 years. The unhealthy food intake was assessed by food frequency intake and SEP was evaluated with the family affluence scale. We observed that unhealthy food intakes decreased through the years, showing the apparent decline when nutritional policies focusing on the restriction of unhealthy foods were implemented, and the trend was all same in the different SEP groups. The pattern of unhealthy food intakes by SEP has changed before and after implementation of the policies. The intakes of carbonated beverages, fast food, and confectioneries were higher in the higher SEP group before implementation of the policies but the difference was not shown after implementation of the policies. The intake of instant noodles was consistently higher in the lower SEP group. The risk of frequent consumption of unhealthy foods was generally more decreased through the years in the higher SEP group than the lower SEP group. In conclusion, this study found the positive effect of nutritional policy on unhealthy food intake among adolescents and the high SEP group appeared to undergo greater desirable changes in dietary behaviors after implementation of nutritional policies than the low SEP group.

    2012-05-01

    This study examined physiological correlates (cortisol and α-amylase [AA]) of peer victimization and aggression in a sample of 228 adolescents (45% male, 55% female; 90% African American; M age = 14 years, SD = 1.6 years) who participated in a longitudinal study of stress, physiology, and adjustment. Adolescents were classified into victimization/aggression groups based on patterns with three waves of data. At Wave 3, youth completed the Social Competence Interview (SCI), and four saliva samples were collected prior to, during, and following the SCI. Repeated-measures analyses of variance with victimization/aggression group as the predictor, and physiological measures as outcomes, controlling for time of day, pubertal status, and medication use revealed significant Group × SCI Phase interactions for salivary AA (sAA), but not for cortisol. The results did not differ by sex. For analyses with physical victimization/aggression, aggressive and nonaggressive victims showed increases in sAA during the SCI, nonvictimized aggressors showed a decrease, and the normative contrast group did not show any change. For analyses with relational victimization/aggression, nonaggressive victims were the only group who demonstrated sAA reactivity. Incorporating physiological measures into peer victimization studies may give researchers and clinicians insight into youth's behavior regulation, and help shape prevention or intervention efforts.

    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.

Thirty obese childrenaged 10 to 16 years, with a body mass index (BMI above the 95th percentile according to theclassification proposed by the Centers for Disease Control and Prevention (CDC, 2000, weredivided into two groups: the first group started learning to swim (GSwim, n = 10 and the secondgroup underwent a deep water running program (GDeep, n = 20. Weight, height, BMI, BMIZ-scores, relative and absolute fat, and relative and absolute lean body mass were evaluated atbaseline and after 12 weeks. The program consisted of 12 meetings for nutritional guidance (oncea week and 36 sessions of exercise (three times per week. MANOVA and Fisher’s exact testwere used for statistical analysis, with the level of significance set at p < 0.05. After 12 weeks,GDeep showed a significant reduction in BMI, BMI Z-scores and relative and absolute fat,and an increase in relative and absolute lean body mass. Significant differences were observedbetween GDeep and GSwim in terms of the reduction in body fat (p = 0.014 and the increasein lean mass (p = 0.006. A program of deep water running together with nutritional guidancemay promote significant changes in the body composition of obese children and adolescents dueto the cyclic characteristic of this physical activity.

Aim of the study: This study was designed to detect the effect of diet therapy (through nutrition education program on lipid profile and blood glucose level in diabetic children. Subjects and Methods: The study was carried on 45 diabetic children aged between 8-15 years old at diabetic nutrition clinic of nutrition institute in Cairo from 2003-2005. Children included in the study were divided into two groups: insulin dependent dyslipidemic group (IDDM (diet control/ group and insulin dependent non dyslipidemic (control group. All were subjected to full dietetic history by the 24 hour recall for 3 days, thorough clinical examination, they were evaluated for plasma lipids, lipoproteins, fasting blood glucose (FBG and glycated hemoglobin (HbA1c levels. The dyslipidemic were measured after three months for the previously measured parameters. The nutrition education process was performed and continued on weekly intervals for three months. Results: There was significant decrease in serum cholesterol and triglyceride levels in the study group after the program, and insignificant increase in serum HDL and decrease in serum LDL. Also, there was insignificant decrease in FBG but there was statistically significant decrease in HbA1 after the program. These changes occurred in parallel with increases in intakes of protein and total calories with adequate carbohydrate and sometimes a reduction in intakes of total fat. Conclusion: Nutrition therapy for children with IDDM is essential to improve measures of glycemic control and lipoprotein mediated risk for dyslipidemia. More innovative approaches to achieve lifestyle changes are required to meet current recommendations which are likely to produce greater beneficial changes than those observed in this study

    2016-06-01

    Full Text Available Abstract Objective: To address the association between food and nutrition insecurity and cardiometabolic risk factors in childhood and adolescence. Data source: Articles were selected from the Medline, Lilacs and SciELO databases with no publication date limit, involving children and adolescents, using the descriptors: food and nutrition security, diabetes mellitus, hypertension, metabolic syndrome, stress and dyslipidemia. The terms were used in Portuguese, English and Spanish. The search was carried out systematically and independently by two reviewers. Data synthesis: Exposure to food insecurity during childhood and adolescence ranged from 3.3% to 82% in the selected publications. Exposure to food insecurity was associated with stress, anxiety, greater chance of hospitalization, nutritional deficiencies, excess weight and inadequate diets with reduced intake of fruits and vegetables and increased consumption of refined carbohydrates and fats. Conclusions: Food and nutrition insecurity was associated with the presence of cardiometabolic risk factors in the assessed publications. Childhood and adolescence constitute a period of life that is vulnerable to food insecurity consequences, making it extremely important to ensure the regular and permanent access to food. Because this is a complex association, some difficulties are found, such as the synergy between risk factors, the assessment of heterogeneous groups and extrapolation of data to other populations, in addition to the influence of environmental factors.

    We evaluate the influence of demographic, socioeconomic, and maternal variables on the nutritional status of adolescents aged 11 years. We conducted a prospective cohort study including 4,452 adolescents born in Pelotas, Southern Brazil, in 1993, accounting for 87.5% of the original cohort. Nutritional status was evaluated based on World Health Organization criteria. Subjects were classified according to nutritional status into thin, normal, overweight and obese. Independent variables analyzed included skin color, socioeconomic status, maternal schooling, and maternal body mass index (BMI). Analyses were stratified by sex, and multivariable regression was performed using the multinomial logistic approach. Overall, 7% of adolescents were classified as thin, 11.6% as overweight, and 11.6% as obese. Among boys, thinness was inversely associated with maternal schooling and maternal BMI. Among girls, thinness was directly associated with maternal BMI. Overweight and obesity were directly associated with socioeconomic status and maternal BMI, the former showing the strongest association with nutritional status among adolescents. PMID:20963286

    Full Text Available The purpose of this study was to analyze the relationships between 100-m front crawl swimming performance and relevant biomechanical, anthropometrical and physiological parameters in male adolescent swimmers. Twenty five male swimmers (mean ± SD: age 15. 2 ± 1.9 years; height 1.76 ± 0.09 m; body mass 63.3 ± 10.9 kg performed an all-out 100-m front crawl swimming test in a 25-m pool. A respiratory snorkel and valve system with low hydrodynamic resistance was used to collect expired air. Oxygen uptake was measured breath-by-breath by a portable metabolic cart. Swimming velocity, stroke rate (SR, stroke length and stroke index (SI were assessed during the test by time video analysis. Blood samples for lactate measurement were taken from the fingertip pre exercise and at the third and fifth minute of recovery to estimate net blood lactate accumulation (?La. The energy cost of swimming was estimated from oxygen uptake and blood lactate energy equivalent values. Basic anthropometry included body height, body mass and arm span. Body composition parameters were measured using dual-energy X-ray absorptiometry (DXA. Results indicate that biomechanical factors (90.3% explained most of 100-m front crawl swimming performance variability in these adolescent male swimmers, followed by anthropometrical (45.8% and physiological (45.2% parameters. SI was the best single predictor of performance, while arm span and ∆La were the best anthropometrical and physiological indicators, respectively. SI and SR alone explained 92.6% of the variance in competitive performance. These results confirm the importance of considering specific stroke technical parameters when predicting success in young swimmers.

    Honey bees are exposed to a variety of environmental factors that impact their health, including nutritional stress, pathogens, and pesticides. In particular, there has been increasing evidence that sublethal exposure to pesticides can cause subtle, yet important effects on honey bee health and behavior. Here, we add to this body of knowledge by presenting data on bee-collected pollen containing sublethal levels of cyhalothrin, a pyrethroid insecticide, which, when fed to young honey bees, resulted in significant changes in lifespan, nutritional physiology,and behavior. For the first time, we show that when young, nest-aged bees are presented with pollen containing field-relevant levels of cyhalothrin, they reduce their consumption of contaminated pollen. This indicates that, at least for some chemicals, young bees are able to detect contamination in pollen and change their behavioral response, even if the contamination levels do not prevent foraging honey bees from collecting the contaminated pollen.

    The development of antisocial behavior in youth has been examined with neurobiological theories that suggest adolescents who are less responsive to their environments are less likely to develop empathy in the absence of extant physiological arousal. However, little attention is paid to these individuals’ social context. Individuals with adverse early experiences can also exhibit attenuated physiological arousal. The current investigation examines whether psychopathic symptoms or life stress e...

    Full Text Available Background: Dietary polyamines have been shown to give a significant contribution to the body pool of polyamines. Knowing the levels of polyamines (putrescine, spermidine, and spermine in different foods and the contribution of daily food choice to polyamine intake is of interest, due to the association of these bioactive amines to health and disease. Objective: To estimate polyamine intake and food contribution to this intake in adolescents compared to a diet fulfilling the Swedish Nutrition Recommendations. Design: A cross-sectional study of dietary intake in adolescents and an ‘ideal diet’ (Swedish nutrition recommendations objectified [SNO] list of foods was used to compute polyamine intake using a database of polyamine contents of foods. For polyamine intake estimation, 7-day weighed food records collected from 93 adolescents were entered into dietetic software (Dietist XP including data on polyamine contents of foods. The content of polyamines in foods recommended according to SNO was entered in the same way. Results: The adolescents’ mean daily polyamine intake was 316±170 µmol/day, while the calculated contribution according to SNO was considerably higher with an average polyamine intake of 541 µmol/day. In both adolescent's intake and SNO, fruits contributed to almost half of the total polyamine intake. The reason why the intake among the adolescents was lower than the one calculated from SNO was mainly due to the low vegetable consumption in the adolescents group. Conclusions: The average daily total polyamine intake was similar to that previously reported in Europe. With an ‘ideal’ diet according to Swedish nutrition recommendations, the intake of this bioactive non-nutrient would be higher than that reported by our adolescents and also higher than that previously reported from Europe.

    Young adolescents were assessed with regard to cognitive, socio-cultural and behavioral components of eating disturbances. An anonymous questionnaire was administered to 5th-8th grade pupils, 280 girls and 251 boys, to assess eating habits, body image, self-confidence, environmental-cultural influences, risk behaviors and socio-economic state. Girls scored consistently higher on all weight-control behaviors. Discontent with own body, and attitudes and behaviors associated with eating disorders, were reported by under-studied populations such as boys and younger girls. Both frequency and severity of weight-control behaviors were associated with "social age." Highly significant differences between scores of 6th and 7th graders indicate that they may be at a time of increased susceptibility. Measuring the influence of the mass media gave inconsistent results. PMID:10883175

    Full Text Available A study was conducted to ascertain the growth and nutritional status of adolescent school girls in rural area. Present study was conducted among adolescent girls studying in 5th to 8th standard (age group of 10 to 14 years of eighteen government approved school in Dantan-II block, Paschim Medinipur district, West Bengal. Physical growths of total of 3611 girls were assessed through anthropometry. Data on weights and heights of girls were collected using standardized techniques. The extent of malnutrition of adolescent girls was evaluated by well-to-do Indian and NCHS median value. The results revealed that the weights and heights of these girls were below those of standard value. As regards weight for age index, only 28.2% subjects were in the normal category and the percentage of subjects suffering from Grade I (25.7%, Grade II (30.4%, Grade III (13.7% and Grade IV (1.9% malnutrition was quite prevalent in present study. With respect to height for age index, 65.2% of the subjects were in the normal category, 32.6% had mild retardation and about 2.2% had poor status. The present study revealed that different grades of malnutrition are widely prevalent among the girls in our study area. All these observations suggest that school going early adolescent girls need better nutrition to combat the problem of under nutrition. Further studies should be made to identify the factors responsible for it.

    Full Text Available The study was carried out to study the nutritional status, develop a product incorporating seaweed and assess its impact on anemic adolescent girls. Five hundred adolescent girls in the age group of 15–18 years were selected from a women's college at Kilakarai, Tamil Nadu, India as the target group to find the prevalence of anemia. Among the 500 subjects 100 with a hemoglobin level of 7–9 g/dL (moderate anemia were selected by purposive sampling technique for supplementation. Seaweed incorporated chocolate was formulated, standardized, tested for consumer acceptability and in vitro iron bioavailability and supplemented to the selected subjects. The result of the study indicates that seaweed chocolate developed obtained the highest score for overall acceptability, 56 mg of iron/100 g and 11.80 mg of bioavailable iron. The results were found to be promising as there was a significant increase in hemoglobin, TIBC, MCH, MCV, serum iron and serum ferritin levels in the selected subjects. Seaweeds are a less consumed natural resource but abundantly available in the coastal areas of India as they are rich source of nutrients and can be used as an effective therapeutic and nutrient adjunct.

    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. PMID:15883552

    The purpose of this study was to design a rewards-based nutrition intervention program to improve knowledge and dietary behaviors of adolescent girls. Our participants consisted of eight girls ages 11 to 13 years. Nutritional knowledge was assessed before and after intervention program through a "Jeopardy" style quiz game and posttest questionnaires. Participants were also interviewed throughout the week about typical dietary behaviors, daily physical activity, and self-esteem. Educational activities took place for 2 to 3 hours each day and included a grocery store scavenger hunt, healthy baking demonstrations, and relay races. Participants received bracelets and charms as rewards for participation in activities. Nutritional knowledge increased for six out of eight participants, although the overall increase was not found to be statistically significant (p = .20). Significant correlations were found between measures including dietary behavior (soda consumption per week and perceived importance of body weight: r = -.827, p = .01), self-esteem (weight and endurance: r = .801, p = .03), and fitness levels (weight and curl-ups completed in 30 seconds: r = -.729, p = .04). This study shows promising evidence that this nutrition education intervention could be effective at increasing nutrition knowledge, thus potentially affecting future dietary behaviors of adolescent girls.

    Iron (Fe)-heme containing fertilizers can effectively prevent Fe deficiency. This paper aims to investigate root physiological responses after a short period of Fe-heme nutrition and Fe deficiency under two pH conditions (with or without HEPES) in the Fe chlorosis-tolerant grapevine rootstock 140 Ruggeri. Organic acids in root exudates, Fe reduction capacity, both roots and root exudates contributions, together with other physiological parameters associated to plant Fe status were evaluated in plants grown in hydroponics. Analyses of root tips by SEM, and Raman and IR spectra of the precipitates of Fe-heme fertilizers were performed. The physiological responses adopted by the tolerant 140 Ruggeri to the application of Fe-heme indicated an increased Fe reduction capacity of the roots. This is the first report showing oxalic, tartaric, malic and ascorbic as major organic acids in Vitis spp. root exudates. Plants reacted to Fe deficiency condition exuding a higher amount of ascorbic acid in the rhizosphere. The presence of HEPES in the medium favoured the malic acid exudation. The lowest concentration of oxalic acid was found in exudates of plants subjected to Fe-heme and could be associated to a higher accumulation in their root tips visualized by SEM analysis.

    Effortful control is thought to foster adaptive action in defensive contexts and may thereby protect individuals against anxious inhibition and focus on their own distress. We examined if effortful control predicted adolescents' perceived arousal, unpleasantness, and control as well as autonomic (heart rate [HR]) and hypothalamic-pituitary-adrenal axis (cortisol) responses during social stress. The data came from a focus sample of the Tracking Adolescents' Individual Lives Survey, a prospective population study of Dutch adolescents (N = 715, 50.9% girls; mean age = 16.11, SD = 0.59), who participated in a laboratory session including a social stress task (public speaking and mental arithmetic). Perceived and physiological stress measures were assessed before, during, and after the social stress task. Effortful control was measured using various questionnaires and informants, as well as by means of a reaction time (RT) task assessing response inhibition. Overall, adolescents with high questionnaire-based effortful control tended to feel more relaxed, pleasant, and in control during the laboratory session than adolescents with lower levels of control and had stronger HR responses to the stress test. Adolescent girls with high inhibitory control as measured by the RT task also had strong HR responses, but inhibitory control was associated with high rather than low perceived arousal. Our results suggest that both questionnaire and RT measures of effortful control predict strong HR responses to challenging situations, but associational patterns diverge with regard to perceived stress measures.

  16. Bone mineral density and nutritional indices in adolescent females with recently diagnosed anorexia

    International Nuclear Information System (INIS)

    Full text: Osteopenia/osteoporosis and fractures have been shown to occur with anorexia nervosa (AN). This study evaluated adolescent females diagnosed with AN less than 12 months previously to determine the presence of any significant bone mass reduction at this early stage of diagnosis and to evaluate the correlation between total body (TB) and lumbar spine (LS) bone mineral densities (BMD) and bone mineral content (BMC), and nutritional indices (body weight, body mass index (BMI), lean mass, fat mass and percentage fat). The subjects were 22 adolescent females aged 12-17 years (mean= 14.3 years) diagnosed with AN less than 12 months earlier (range 2.5-11 months; mean = 6.7 months). They had bone density measurements of the TB and LS using a Lunar DPX-L densitometer. Comparison was made with values of age-matched controls in the Lunar normative database. Although there was a tendency towards low TB and LS bone mass, these changes were not statistically significant. Bivariate analyses showed significant correlation between TB BMD and lean mass (P < 0.001) and weight (P < 0.001) and between TB BMC and lean mass (P < 0.001) and weight (P < 0.01). There was similar significant correlation between LS BMD and lean mass (P < 0.01) and weight (P<0.01), and between LS BMC and lean mass (P < 0.01) and weight (P < 0.01). With stepwise regression analysis, only lean mass remained significantly correlated with TB BMD and BMC and LS BMD and BMC. There was no longer any significant correlation with weight. In this study, the weight percentile was found to be correlated highly with the LS BMD Z-score (P < 0.01). Therefore, during adolescence, the lean mass in particular, but also body weight, are good indicators of bone densities. Adolescent females do not appear to show bone mass reduction in the early stages of diagnosis of anorexia nervosa. This suggests early intervention may preserve bone gain and attainment of normal peak bone mass

  20. Correlations between blood lead levels and some physiological and biochemical parameters of nutritional importance in some Nigerian women

    International Nuclear Information System (INIS)

    Lead is one of the common toxic materials widely occurring in the Nigerian environment. Even with the change to unleaded petrol, other significant sources still remain to be addressed. The deleterious impact of lead on human health, is well documented. The effects range from attention-grabbing mass mortality - as happened in Zamfara State recently, to no less serious but grossly neglected neurocognitive and neurodevelopmental effects, including lowered intelligence quotient scores. All these impacts are most serious in children, especially fetuses who receive their burden from their mothers. Ninety percent of lead in most adults resides in the bones with a half-life measured in decades. Therefore, fetuses and breast-fed children in this generation will remain seriously at risk of exposure to damaging lead levels no matter the efforts to rid our external environment of lead in the years to come. In this work, we have investigated the correlation between Blood Lead Levels (BLL) and up to 35 physiological and biochemical parameters of nutritional importance in 62 women of child-bearing age from lIe-lfe, Nigeria. BLL was determined in venous blood using Inductively- coupled plasma Mass Spectrometry. Our results show that BLL significantly correlates with Packed Cell Volume (PCV), Creatine Clearance, and the ratio of Low-density Lipids to High density Lipids in these women. When the subjects were stratified into different Nutritional Status group based on their Body Mass Index, significant correlation was found between BLL and Age but only in Obese subjects.

    Full Text Available A antropometria tem sido apontada como o parâmetro mais indicado para avaliar o estado nutricional coletivo. A avaliação nutricional coletiva de adolescentes possui uma dinâmica muito peculiar por se tratar de um momento de intensas mudanças fisiológicas e psicossociais, diretamente associadas à dinâmica nutricional deste grupo. O acompanhamento dessa dinâmica e de suas variáveis intervenientes e interativas é, portanto, um tema de discussão extremamente relevante. Esta revisão tem por objetivo apresentar as aplicações de parâmetros antropométricos à avaliação do estado nutricional de adolescentes. Conclui-se que, enquanto não houver metodologia simples de avaliação da composição corporal, para estudos epidemológicos deve-se manter o uso do índice de massa corporal, associado ou não às variáveis de dobra cutânea e perímetros. Apesar das dificuldades e limitações, as evidências apontam para uma fundamental incorporação das informações sobre a maturação sexual à avaliação do estado nutricional coletivo de adolescentes. Além disso, as investigações devem atentar mais aos parâmetros de definição da população que estará sendo estudada, cuidando, para permitir a comparação entre os estudos.Anthropometry is considered the most appropriate tool for assessing the nutritional status of groups of people.

    Full Text Available Sertraline is a clinically effective Selective Serotonin Reuptake Inhibitor known to increase and stabilize serotonin levels. This neurotransmitter plays an important role in adolescent brain development in both rodents and humans, and its dysregulation has been correlated with deficits in behaviour and emotional regulation. Since prenatal stress may disturb serotoninergic homeostasis, the aim of this study was to examine the long-lasting effects of exposure to sertraline throughout adolescence on behavioural and physiological developmental parameters in prenatally stressed Wistar rats. Sertraline was administered (5mg/kg/day p.o. from the age of 1-3 months to half of the progeny, of both sexes, of gestating dams stressed by use of a restraint (PS or not stressed. Our data reveal that long-term sertraline treatment slightly reduced weight gain in both sexes, but reversed the developmental disturbed ‘catch-up’ growth found in PS females.Neither prenatal stress nor Sertraline treatment induced remarkable alterations in behaviour and had no effects on mean startle reflex values. However, a sex-dependent effects of PS was found: in males the PS paradigm slightly increased anxiety-like behaviour in the open field, while in females, it impaired startle habituation. In both cases, sertraline treatment reversed the phenomena. Additionally, the PS animals exhibited a disturbed leukocyte profile in both sexes, which was reversed by sertraline.The present findings are evidence that continuous sertraline administration from adolescence through adulthood is safe in rodents and lessens the impact of prenatal stress in rats.

The data were subjected to comparision for nutritional assessment by using two study tools i.e., conventional BMI and EHPA chart. Statistical analysis: Proportion and Chi square test by using epi info statistical package. Result:   A total of 467 adolescents were examined. By using conventional BMI, 93.79% of adolescents were classified as underweight and 4.06% as normal; however with the help of EHPA chart it was found that 38.97% adolescents were underweight and 58.67% were normal. Conclusion: Existing norms of using conventional BMI for assessing nutritional status of adolescents is inappropriate as far too many normal adolescents fall in undernourished category, whereas EHPA chart prevents such fallacies.

    Digestive enzymatic activity and nutritional responses of Autographa gamma (L.) (Lepidoptera: Noctuidae), an important insect pest of sugar beet, on nine sugar beet cultivars (Peritra, Karolina, Paolita, Lenzier, Tiller, Ardabili, Persia, Rozier, and Dorothea) were studied. The highest proteolytic activity of fourth and fifth instar of A. gamma was in larvae fed on cultivar Persia. The highest amylolytic activity of fourth and fifth instar was observed in larvae fed on cultivars Rozier and Dorothea, respectively. The lowest proteolytic and amylolytic activities in fourth instar were observed on cultivar Tiller; whereas the lowest activities in fifth instar were detected on cultivars Karolina and Tiller, respectively. Larval weight in both larval instars (fourth and fifth) was the heaviest on cultivar Persia and the lightest on cultivar Karolina. Furthermore, weight gain of larvae was the highest on cultivar Persia and the lowest on cultivar Karolina. The results of this study suggest that cultivar Tiller was the most unsuitable host plant for feeding of A. gamma. PMID:27324581

    The Khapra beetle, Trogoderma granarium Everts (Coleoptera: Dermestidae), is known as one of the mostserious pests of grains in many parts of the world. In this study, the effect of nine barley cultivars (‘Bahman’,‘CB-84-10’, ‘Fajr 30’, ‘Makuyi’, ‘Nosrat’, ‘Yousof’, ‘13A1’, ‘18A1’, and ‘19 A1’) and a wheat cultivar (‘MV17’, as a control) was determined on the nutritional indices and digestive enzymatic activity of T. granarium at 33 6 1C,relative humidity of 6565%, and a photoperiod of 14:10 (L:D) h. The highest and lowest values of larval weight gain of sixth instar were detected on wheat (0.757±0.068 mg) and cultivar Bahman (0.342±0.071 mg). Also, T. granarium larvae fed on cultivar Bahman had the lowest value of efficiency of conversion of ingested food(10.90±2.09%) as compared with wheat and other barley cultivars. Also, the highest midgut amylolytic and proteolytic activities of sixth instar were on cultivar Bahman (0.364±0.024 mU/mg and 80.54±1.73 U/mg, respectively)and the lowest activities were on cultivar Nosrat (0.043±0.004 mU/mg and 7.15±0.01 U/mg, respectively).It is concluded that barley cultivar Bahman was the most unsuitable host for feeding of T. granarium.

    Full Text Available Objectives: In this study, we aimed to investigate the long term associations between breastfeeding duration during infancy, diet quality as measured by a diet score at one year of age and cognitive performance during adolescence.Methods: Participants (n= 717 were recruited from the West Australian Pregnancy Cohort (Raine Study, a prospective longitudinal study of 2868 children and their families based in Perth, Western Australia. Breastfeeding duration and an early diet score at age one year were used as the main predictor variables, while a computerized cognitive battery (CogState was used to assess adolescents’ cognitive performance at 17 years. The diet score, which has seven food group components, was based on a 24-hour recall questionnaire completed by the mother at one year of age. A higher diet score represents a better, more nutritious eating pattern. Associations between breastfeeding duration, diet score and cognitive performance were assessed in multivariable regression models.Results: Higher diet scores at one year representing better diet quality were significantly associated with faster reaction times in cognitive performance at 17 years (Detection Task: β= -0.004, 95% CI: -0.008; 0.000, p= 0.036; Identification Task: β= -0.004, 95% CI: -0.008; 0.000, p= 0.027. Breastfeeding duration (≥ 4 months was also significantly associated with a shorter reaction time, but only for males (Detection Task: β= -0.026, 95% CI: -0.046; -0.006, p= 0.010. Conclusion: Nutrition in early childhood may have a long term association with fundamental cognitive processing speed, which is likely to be related to enhanced brain development in the first year of life.

  13. The Role of Adolescent Nutrition and Physical Activity in the Prediction of Verbal Intelligence during Early Adulthood: A Genetically Informed Analysis of Twin Pairs

    Directory of Open Access Journals (Sweden)

    Dylan B. Jackson

    2015-01-01

    Full Text Available A large body of research has revealed that nutrition and physical activity influence brain functioning at various stages of the life course. Nevertheless, very few studies have explored whether diet and exercise influence verbal intelligence as youth transition from adolescence into young adulthood. Even fewer studies have explored the link between these health behaviors and verbal intelligence while accounting for genetic and environmental factors that are shared between siblings. Employing data from the National Longitudinal Study of Adolescent Health, the current study uses a sample of same-sex twin pairs to test whether youth who engage in poorer fitness and nutritional practices are significantly more likely to exhibit reduced verbal intelligence during young adulthood. The results suggests that, independent of the effects of genetic and shared environmental factors, a number of nutritional and exercise factors during adolescence influence verbal intelligence during adulthood. Limitations are noted and suggestions for future research are outlined.

    Biochemically determined nutritional status measurements in low-income countries are often too expensive. Therefore, we hypothesized that some anthropometrical or functional measurements (handgrip) could reflect nutritional status measured by specific biochemical indicators. We did a population-based study from 1 urban area and 2 rural districts in Zambézia Province of Mozambique. The participants (n=386) were non-pregnant adolescent girls between 15 and 18 years of age. 96% had a normal BMI-for-age score. Weight and mid-upper arm circumference (MUAC) were highly correlated (r>0.8) with each other and with total body muscle mass, body mass index (BMI), and with waist circumference, as well as with skinfolds (r>0.6). Upper and total arm lengths were correlated (r>0.7) with height and with each other, and right and left handgrip were correlated only with each other, as were triceps and subscapular skinfolds (r>0.7). Serum albumin correlated negatively with waist circumference (Padolescent girls in low-income countries. When nutrition transition proceeds, waist circumference together with MUAC could form tools for the prediction of worsening of nutritional status. PMID:27440538

  16. Palm oil: biochemical, physiological, nutritional, hematological, and toxicological aspects: a review.

    Edem, D O

    2002-01-01

    The link between dietary fats and cardiovascular diseases has necessitated a growing research interest in palm oil, the second largest consumed vegetable oil in the world. Palm oil, obtained from a tropical plant, Elaeis guineensis contains 50% saturated fatty acids, yet it does not promote atherosclerosis and arterial thrombosis. The saturated fatty acid to unsaturated fatty acid ratio of palm oil is close to unity and it contains a high amount of the antioxidants, beta-carotene, and vitamin E. Although palm oil-based diets induce a higher blood cholesterol level than do corn, soybean, safflower seed, and sunflower oils, the consumption of palm oil causes the endogenous cholesterol level to drop. This phenomenon seems to arise from the presence of the tocotrienols and the peculiar isomeric position of its fatty acids. The benefits of palm oil to health include reduction in risk of arterial thrombosis and atherosclerosis, inhibition of endogenous cholesterol biosynthesis, platelet aggregation, and reduction in blood pressure. Palm oil has been used in the fresh state and/or at various levels of oxidation. Oxidation is a result of processing the oil for various culinary purposes. However, a considerable amount of the commonly used palm oil is in the oxidized state, which poses potential dangers to the biochemical and physiological functions of the body. Unlike fresh palm oil, oxidized palm oil induces an adverse lipid profile, reproductive toxicity and toxicity of the kidney, lung, liver, and heart. This may be as a result of the generation of toxicants brought on by oxidation. In contrast to oxidized palm oil, red or refined palm oil at moderate levels in the diet of experimental animals promotes efficient utilization of nutrients, favorable body weight gains, induction of hepatic drug metabolizing enzymes, adequate hemoglobinization of red cells and improvement of immune function. Howerer, high palm oil levels in the diet induce toxicity to the liver as shown by

    Abstract Objective: To evaluate the correlation between the number of leukocytes and cardiovascular risks associated with birth characteristics, nutritional status and biochemical tests. Methods: Cross-sectional study developed with 475 adolescents, born between 1992 and 2001, in the municipality of Viçosa (MG). Maternal medical records were analyzed in the hospital units, and the following was recorded: birth weight and length, head circumference, chest circumference, Apgar score, gestational age. In adolescents, body mass index, skinfold thickness, body composition, blood count, biochemical tests and clinical variables were also assessed. The statistical analyses was carried out using Statistical Package for Social Sciences (SPSS) version 20.0 and Data Analysis and Statistical Software (STATA) with Kruskal–Wallis, Mann–Whitney, chi-square or Fisher's exact tests and Linear Regression. Significance level was set at α<0.05. The study was approved by the Research Ethics Committee of UFV for studies with human subjects. Results: Weight and birth length, head and chest circumference were higher among boys. In adolescents, the number of leukocytes was higher in individuals with excess weight and body fat and high adiposity index, waist-to-height ratio and waist circumference. Only altered triglycerides showed differences between leukocyte medians. Regardless of the anthropometric variable of the final regression model, the stage of adolescence, number of platelets, eosinophils, monocytes and lymphocytes were associated with the increase in leukocytes. Conclusions: The birth variables were not associated with changes in leukocyte numbers, whereas the anthropometric variables were good indicators for a higher leukocyte count, regardless of the stage of adolescence and gender.

    Introduction The prevalence of paediatric obesity is increasing, and with it, lifestyle-related diseases in children and adolescents. High-intensity interval training (HIIT) has recently been explored as an alternate to traditional moderate-intensity continuous training (MICT) in adults with chronic disease and has been shown to induce a rapid reversal of subclinical disease markers in obese children and adolescents. The primary aim of this study is to compare the effects of HIIT with MICT on myocardial function in obese children and adolescents. Methods and analysis Multicentre randomised controlled trial of 100 obese children and adolescents in the cities of Trondheim (Norway) and Brisbane (Australia). The trial will examine the efficacy of HIIT to improve cardiometabolic outcomes in obese children and adolescents. Participants will be randomised to (1) HIIT and nutrition advice, (2) MICT and nutrition advice or (3) nutrition advice. Participants will partake in supervised exercise training and/or nutrition sessions for 3 months. Measurements for study end points will occur at baseline, 3 months (postintervention) and 12 months (follow-up). The primary end point is myocardial function (peak systolic tissue velocity). Secondary end points include vascular function (flow-mediated dilation assessment), quantity of visceral and subcutaneous adipose tissue, myocardial structure and function, body composition, cardiorespiratory fitness, autonomic function, blood biochemistry, physical activity and nutrition. Lean, healthy children and adolescents will complete measurements for all study end points at one time point for comparative cross-sectional analyses. Ethics and dissemination This randomised controlled trial will generate substantial information regarding the effects of exercise intensity on paediatric obesity, specifically the cardiometabolic health of this at-risk population. It is expected that communication of results will allow for the development of

    Full Text Available Adipose tissue plays a critical role in energy homeostasis and metabolism. There is sparse understanding of the molecular regulation at the protein level of bovine adipose tissues, especially within different fat depots under different nutritional regimes. The objective of this study was to analyze the differences in protein expression between bovine subcutaneous and visceral fat depots in steers fed different diets and to identify the potential regulatory molecular mechanisms of protein expression. Subcutaneous and visceral fat tissues were collected from 16 British-continental steers (15.5 month old fed a high-fat diet (7.1% fat, n=8 or a control diet (2.7% fat, n=8. Protein expression was profiled using label free quantification LC-MS/MS and expression of selected transcripts was evaluated using qRT-PCR. A total of 682 proteins were characterized and quantified with fat depot having more impact on protein expression, altering the level of 51.0% of the detected proteins, whereas diet affected only 5.3%. Functional analysis revealed that energy production and lipid metabolism were among the main functions associated with differentially expressed proteins between fat depots, with visceral fat being more metabolically active than subcutaneous fat as proteins associated with lipid and energy metabolism were upregulated. The expression of several proteins was significantly correlated to subcutaneous fat thickness and adipocyte size, indicating their potential as adiposity markers. A poor correlation (r=0.245 was observed between mRNA and protein levels for 9 genes, indicating that many proteins may be subjected to post-transcriptional regulation. A total of 8 miRNAs were predicted to regulate more than 20% of lipid metabolism proteins differentially expressed between fat depots, suggesting that miRNAs play a role in adipose tissue regulation. Our results show that proteomic changes support the distinct metabolic and physiological characteristics

    Full Text Available Abstract Background Previous research has documented the positive effects of family meals on the dietary quality of adolescents. The objective of the current study is to examine associations between frequency of family meals and body mass index (BMI, other aspects of the home food environment, and related nutrition behaviors. Methods Data were collected during baseline measurements of the Pacific Obesity Prevention In Communities study. In total, 3245 ethnically diverse students completed a questionnaire about their nutrition behaviors and were weighed and measured for height. Results In total, 42% of adolescents ate a family meal on all of the previous five school nights. Frequency of family meals was modestly associated with BMI in bivariate analysis (p = 0.045, but lost significance when demographic characteristics were included in the model. Frequency of family meals was associated with many positive aspects of home food environment and positive nutrition behaviors, including parental support for healthy eating, limits on television use, having fruit available at home, consuming five fruits and vegetables a day, eating breakfast, and bringing lunch from home. Surprisingly, no relationships were observed between frequency of family meals and accessibility and consumption of many high fat/high sugar foods. Conclusion Our findings suggest that the positive effect of family meals may reflect an overall positive home food environment. Families who have meals together have more healthful foods available at home and support their child in eating healthfully. There were no relationships between family meals and high fat/high sugar foods; this suggest that while families may prioritize eating together, messages about limiting the availability and consumption of these snack foods are not getting through.

    Full Text Available INTRODUCTION: HIV-infected children and adolescents treated with highly active antiretroviral therapy (HAART regimens that include a protease inhibitor (PI can show significant improvements in clinical outcomes, nutritional status and quality of life. The study aimed to report nutritional and metabolic alterations for pediatric patients continuously exposed to HAART and for healthy controls for up to 1 year. METHODS: Clinical, anthropometric, lipid profile and food intake data were collected prospectively over approximately 12-months for each patient. RESULTS: Fifty-one individuals were studied, of these, 16 were healthy. After 12 months follow-up, HIV-positive individuals remained below the healthy control group parameters. No change was observed concerning food intake. Triglyceride serum levels were higher in patients using protease inhibitor at the onset of the study [PI groups: 114 (43 - 336, and 136 (63 - 271 versus control group: 54.5 (20 - 162; p = 0.003], but after twelve months follow-up, only the group using protease inhibitor for up to two months presented higher values [140 (73 - 273 versus 67.5 (33 - 117; p = 0.004]. HDL-cholesterol was lower in HIV-positive individuals [HIV-positive groups: 36 (27 - 58 and 36 (23 - 43; control 49.5 (34 - 69; p = 0.004]. CONCLUSIONS: HIV-infected children and adolescents treated with highly active antiretroviral therapy showed compromised nutritional parameters compared to a paired healthy control group. Individuals using protease inhibitor presented worse triglyceride serum levels compared to their healthy counterparts.

    Introduction Low levels of food security are associated with dyslipidemia and chronic disease in adults, particularly in women. There is a gap in knowledge about the relationship between food security among youth and dyslipidemia and chronic disease. We investigated the relationship between food security status and dyslipidemia among low-income adolescents. Methods We analyzed data from adolescents aged 12 to 18 years (N = 1,072) from households with incomes at or below 200% of the federal poverty level from the National Health and Nutrition Examination Survey (NHANES) 2003–2010. We used logistic regression to examine the relationship between household food security status and the odds of having abnormalities with fasting total cholesterol (TC), low-density lipoprotein cholesterol (LDL-C), serum triglycerides (TGs), high-density lipoprotein cholesterol (HDL-C), TG/HDL-C ratio, and apolipoprotein B (Apo B). Models included age, sex, race/ethnicity, smoking status, partnered status in the household, and maternal education, with additional adjustment for adiposity. Results Household food security status was not associated with elevated TC or LDL-C. Adolescents with marginal food security were more likely than food-secure peers to have elevated TGs (odds ratio [OR] = 1.86; 95% confidence interval [CI], 1.14–3.05), TG/HDL-C ratio (OR = 1.74; 95% CI, 1.11–2.82), and Apo B (OR = 1.98; 95% CI, 1.17–3.36). Female adolescents with marginal food security had greater odds than male adolescents of having low HDL-C (OR = 2.69; 95% CI, 1.14–6.37). No elevated odds of dyslipidemia were found for adolescents with low or very low food security. Adjustment for adiposity did not attenuate estimates. Conclusion In this nationally representative sample, low-income adolescents living in households with marginal food security had increased odds of having a pattern consistent with atherogenic dyslipidemia, which represents a cardiometabolic burden above their risk from adiposity

    The importance of physical activity to health is well recognized. Good health habits should begin from a young age. This article aims to explore physical activity among Malaysian school adolescents and factors associated with it. Data from the Malaysian School-Based Nutrition Survey (MSNS), comprising a nationally representative sample of school-going children aged 10 to 17 years, were used. The overall prevalence of physically inactive adolescents was 57.3%. Age in years (adjusted odds ratio = 1.2; 95% confidence interval = 1.16-1.23), gender - females (adjusted odds ratio = 2.9; 95% confidence interval = 2.66-3.10), afternoon school session, breakfast consumption (no breakfast and irregular breakfast), body mass index status (obese and underweight), and body weight perception (underweight perceivers) were significant factors associated with physical inactivity among Malaysian adolescents. Thus, there is evidence that programs to promote physical activity in this group should consider the combination of the aforementioned factors at the household, school, and community levels.

    Full Text Available In this paper, we investigated two questions: (1 can measurements of anthropometric and physiological attributes substitute for expert assessment of adolescent basketball players, and (2 how much does the quantitative assessment of a player vary among experts? The first question is relevant to the potential simplification of the player selection process. The second question pertains directly to the validity of expert quantitative assessment. Our research was based on data from 148 U14 female and male basketball players. For each player, an array of anthropometric and physiological attributes was recorded, including body height, body mass, BMI, and several motor skill tests. Furthermore, each player's current ability and potential ability were quantitatively evaluated by two different experts from a group of seven experts. Analysis of the recorded data showed that the anthropometric and physiological attributes explained between 15% and 40% of the variance in experts’ scores. The primary predictive attributes were speed and agility (for predicting current ability and body height and growth potential (for predicting potential ability. We concluded that these attributes were not sufficiently informative to act as a substitute for expert assessment of the players’ current or potential ability. There is substantial variability in different experts' scores of the same player’s ability. However, the differences between experts are mostly in scale, and the relationships between experts’ scores are monotonic. That is, different experts rank players on ability very similarly, but their scores are not well calibrated.

Materials and Methods : A cross-sectional survey. Setting: Schools in South India and the United Arab Emirates. Participants: A total of 2459 adolescent boys and girls between the ages of 10 and 16 years old. Results and Discussion: Anthropometric measurements from 2459 adolescents between the ages of 10-16 years old, 1200 from India and 1259 from UAE, were collected. The subjects were divided into six age groups with 1-year intervals. Adolescents falling below the age and gender-specific 5 th percentile and 3 rd percentile of the WHO recommended standards were defined as having thinness and stunting accordingly. Regardless of gender, the rate of stunting was higher in Indian adolescents from India (25.5-51% when compared with Indian adolescents in UAE (3.1-21%. Thinness was also more in those in India (42-75.4%. When compared with adolescents living in the UAE (4.5-14.4%. The study was done in two groups having a common ethnicity but living in different socio-economic environments. With the results of this study, we can say that improved economic conditions favor better expression of genetic potential for physical growth.

    The Trier Social Stress Test (TSST) was employed to study response to social evaluative threat in male adolescents with Autism Spectrum Disorder (ASD, n = 21) and typical development (n = 13). Participants wore a mobile electrocardiogram to collect heart rate data. There were significant group effects on respiratory sinus arrhythmia (RSA), a measure of parasympathetic nervous system function, with lower values in ASD (F = 4.97). Bivariate correlations also showed a significant relationship between parent reports of social problems and RSA response to the TSST (r = -0.586). These findings suggest that autonomic dysregulation may contribute to social deficits in adolescents with ASD. PMID:27318810

    Uric acid is associated with cardiovascular disease and cardiovascular disease risk factors in adults, including chronic kidney disease, coronary artery disease, stroke, diabetes mellitus, preeclampsia, and hypertension. We examined the association between uric acid and elevated blood pressure in a large, nationally representative cohort of US adolescents, a population with a relatively low prevalence of cardiovascular disease and cardiovascular disease risk factors. Among 6036 adolescents 12 to 17 years of age examined in the 1999-2006 National Health and Nutrition Examination Survey, the mean age was 14.5 years, 17% were obese (body mass index: ≥95th percentile), and 3.3% had elevated blood pressure. Mean serum uric acid level was 5.0 mg/dL, and 34% had a uric acid level ≥5.5 mg/dL. In analyses adjusted for age, sex, race/ethnicity, and body mass index percentile, the odds ratio of elevated blood pressure, defined as a systolic or diastolic blood pressure ≥95th percentile for age, sex, and height, for each 0.1-mg/dL increase in uric acid level was 1.38 (95% CI: 1.16-1.65). Compared with uric acid level ≥5.5 mg/dL had a 2.03 times higher odds of having elevated blood pressure (95% CI: 1.38-3.00). In conclusion, increasing levels of serum uric acid are associated with elevated blood pressure in healthy US adolescents. Additional prospective studies and clinical trials are needed to determine whether uric acid is merely a marker in a complex metabolic pathway or causal of hypertension and, thus, a potential screening and therapeutic target.

    We investigated whether dietary and urinary Na is associated with adiposity in Korean children and adolescents (10-18 years), a population with a high salt intake. Study subjects were Korean children and adolescents who participated in the cross-sectional nationally representative Korea National Health and Nutrition Examination Survey (2010-2011). This study used measures of dietary (24-h dietary recall) and urinary Na (Na:creatinine ratio) and three methods to determine obesity (BMI, waist circumference (WC) and total body per cent fat (TBPF)). Higher Na intake was significantly associated with obesity, adjusting for the covariates. Subjects in the highest tertile of urinary Na excretion had a significantly higher OR for higher adiposity compared with those in the lowest tertile (multivariate-adjusted OR 3·13 (95% CI 1·81, 5·50) for BMI, 2·15 (95% CI 1·27, 3·66) for WC and 1·92 (95% CI 1·29, 2·86) for TBPF, respectively). Na intake estimated by the 24-h recall method also showed significant association with adiposity (multivariate-adjusted OR 2·79 (95% CI 1·66, 4·68) for BMI and 2·14 (95% CI 1·25, 3·67) for WC, respectively). The significant associations between Na and adiposity remained significant after additionally adjusting for sugar-sweetened beverage (SSB) consumption. Our results revealed a significant positive association between urinary and dietary Na and adiposity in Korean children and adolescents, independent of SSB consumption. PMID:26759221

    The aims of the present position paper by the Committee on Nutrition of the French Society of Paediatrics were to summarize the recently published data on vitamin D in infants, children and adolescents, i.e., on metabolism, physiological effects, and requirements and to make recommendations on supplementation after careful review of the evidence. Scientific evidence indicates that calcium and vitamin D play key roles in bone health. The current evidence, limited to observational studies, however, does not support other benefits for vitamin D. More targeted research should continue, especially interventional studies. In the absence of any underlying risk of vitamin D deficiency, the recommendations are as follows: pregnant women: a single dose of 80,000 to 100,000 IU at the beginning of the 7th month of pregnancy; breastfed infants: 1000 to 1200 IU/day; children less than 18 months of age, receiving milk supplemented with vitamin D: an additional daily dose of 600 to 800 IU; children less than 18 months of age receiving milk not supplemented with vitamin D: daily dose of 1000 to 1200 IU; children from 18 months to 5 years of age: 2 doses of 80,000 to 100,000 IU every winter (November and February). In the presence of an underlying risk of vitamin D deficiency (dark skin; lack of exposure of the skin to ultraviolet B [UVB] radiation from sunshine in summer; skin disease responsible for decreased exposure of the skin to UVB radiation from sunshine in summer; wearing skin-covering clothes in summer; intestinal malabsorption or maldigestion; cholestasis; renal insufficiency; nephrotic syndrome; drugs [rifampicin; antiepileptic treatment: phenobarbital, phenytoin]; obesity; vegan diet), it may be justified to start vitamin D supplementation in winter in children 5 to 10 years of age as well as to maintain supplementation of vitamin D every 3 months all year long in children 1 to 10 years of age and in adolescents. In some pathological conditions, doses of vitamin D can

    Physiological correlates of behavioral and emotional problems, substance use onset and initiation of risky sexual behavior have not been studied in adolescents with prenatal drug exposure. We studied the concordance between baseline respiratory sinus arrhythmia (RSA) at age 3 and baseline cortisol levels at age 11. We hypothesized that children who showed concordance between RSA and cortisol would have lower neurobehavioral disinhibition scores which would in turn predict age of substance use onset and first sexual intercourse. The sample included 860 children aged 16 years participating in the Maternal Lifestyle Study, a multisite longitudinal study of children with prenatal exposure to cocaine and other substances. Structural equation modeling was used to test pathways between prenatal substance exposure, early adversity, baseline RSA, baseline cortisol, neurobehavioral disinhibition, drug use, and sexual behavior outcomes. Concordance was studied by examining separate male and female models in which there were statistically significant interactions between baseline RSA and cortisol. Prenatal substance exposure was operationalized as the number of substances to which the child was exposed. An adversity score was computed based on caregiver postnatal substance use, depression and psychological distress, number of caregiver changes, socioeconomic and poverty status, quality of the home environment, and child history of protective service involvement, abuse and neglect. RSA and cortisol were measured during a baseline period prior to the beginning of a task. Neurobehavioral disinhibition, based on composite scores of behavioral dysregulation and executive dysfunction, substance use and sexual behavior were derived from questionnaires and cognitive tests administered to the child. Findings were sex specific. In females, those with discordance between RSA and cortisol (high RSA and low cortisol or low RSA and high cortisol) had the most executive dysfunction which, in

NEAT Girls is a 12-month multi-component school-based intervention developed in reference to Social Cognitive Theory and includes enhanced school sport sessions, interactive seminars, nutrition workshops, lunch-time physical activity (PA sessions, PA and nutrition handbooks, parent newsletters, pedometers for self-monitoring and text messaging for social support. The following variables were assessed at baseline and will be completed again at 12- and 24-months: adiposity, objectively measured PA, muscular fitness, time spent in sedentary behaviors, dietary intake, PA and nutrition social-cognitive mediators, physical self-perception and global self-esteem. Statistical analyses will follow intention-to-treat principles and hypothesized mediators of PA and nutrition behavior change will be explored. Discussion NEAT Girls is an innovative intervention targeting low-active girls using evidence-based behavior change strategies and nutrition and PA messages and has the potential to prevent unhealthy weight gain and reduce the decline in physical activity and poor dietary habits associated with low socio-economic status. Few studies have reported the long-term effects of school-based obesity prevention programs and the current study has the potential to make an

    Background: Upper arm composition is a reflection of body protein and calorie reserves. However, there is a paucity of data on upper arm composition of children from African countries, including Nigeria. This study aimed to determine the composition of upper arm and nutritional status of school children in Abeokuta, Nigeria and to compare with international reference standards. The sensitivity and specifi city of upper arm muscle area by height (UAMAH) as a nutritional assessment tool was also determined. Methods: Five hundred and seventy children aged 5 to 19 years were selected from seven schools using multistage random sampling. Weight, height, mid-upper arm circumference (MUAC) and triceps skin fold thickness (TSF) were measured. Body mass index, upper arm muscle area (UAMA), upper arm fat area (UAFA), fat percentage and UAMAH were derived. Results: The TSF, UAFA and fat percentage were significantly higher in females than males at each age group. MUAC and UAMA were significantly higher in female children aged 10-14 years, whereas UAMA was significantly higher in male children aged 15-19 years. UAMA and UAFA of the children were lower than those of Americans but similar to those of Zimbabweans, and higher than those of Indians. The sensitivity and specifi city of UAMAH for detecting wasting were 80.8% and 63.9%, respectively, whereas the corresponding values for stunting were 32.2% and 58.2%, respectively. Conclusions: The school children studied have a combination of poor calorie and protein reserve. UAMAH may be a valuable tool for complete evaluation of the nutritional status of school children.

    Background: Studies evaluating the relationship between oral health status and obesity have provided conflicting data. Therefore, there is a great need to investigate and clarify the possible connection in a comprehensive sample. Aims: To assess the relationship of obesity and oral health status among children and adolescents aged 6 to 17 years-old. Study Design: Cross-sectional study. Methods: Data were obtained from 4,534 children and adolescents (2,018 boys and 2,516 girls). Questionnaires were sent home prior to examination; afterwards, anthropometric and dental data were collected from participants. Community Periodontal Index (CPI) and number of decayed, missing, and filled teeth in the permanent dentition (DMFT), and deciduous dentition (dmft) index were used to measure oral health status. Height, body weight, body mass index (BMI), waist circumference (WC), and body fat percentage were analyzed. Results: For DMFT scores, healthy (score=0) girls and boys had significantly higher BMI and WC values than unhealthy (score>1) girls and boys (pobese) at the age of 7 (girls only), 9, 10, and 16 (boys only) years and overall (only girls) (pobesity. Obesity and dental/periodontal diseases are multifactorial diseases that follow similar risk patterns and develop from an interaction between chronic conditions originating early in life. It is important for all health professionals to educate patients at risk about the progression of periodontal and dental diseases and the importance of proper oral hygiene.

    Full Text Available Background and Aim. Trace elements and vitamins play a vital role in human body to perform its function properly. Thalassemic patients are at risk of micronutrient deficiency. This study estimated levels of vitamins A, C, E, B12, folic acid, total homocysteine (tHcy, and methylmalonic acid (MMA along with trace elements, zinc, copper, and selenium in Beta-thalassemia-major patients. Methods. This study included 108 patients with Beta-thalassemia-major and 60 age and sex matched healthy children. Serum levels of vitamin A, E, C, tHcy, and MMA were estimated by high pressure liquid chromatography while serum levels of folic acid and B12 were estimated by thin layer chromatography. Serum zinc, copper, and selenium were determined by atomic absorption spectrometry. Results. There was a significant decrease of vitamins A, C, E, and B12 and trace elements zinc, copper, and selenium in thalassemic patients as compared to controls. tHcy and MMA were significantly elevated in patients. No significant correlations were found between the serum levels of the studied vitamins and trace elements as regards age, frequency of transfusion, duration of transfusion, and serum ferritin. Conclusion. The level of various nutritional biomarkers (vitamins A, C, E, and B12 and trace elements zinc, copper, selenium was reduced in chronically transfused Egyptian thalassemic patient. These patients should have periodic nutritional evaluation and supplementation. Multicenter studies are highly recommended.

    Full Text Available To assess nutritional status of adolescents (10-12 years from non government funded schools (private of Gujarat, India. Teachers & parents of adolescent children were assessed regarding their knowledge, attitude and practices of healthy dietary & lifestyle behaviours. School canteen services were also critically evaluated. Parent’s willingness, to start a nutrition program in the school was also assessed. A cross sectional study was conducted on adolescents (10-12 years from two selected private schools. Anthropometric, biophysical and hemoglobin estimations were done on all children. Lipid and glucose profile was conducted only on over weight (including obese children. Results reveal that canteen offered unhealthy food. Teachers and parents had insufficient knowledge about healthy behaviors. Most (53.5% of the parents agreed to the changes proposed for canteen menus. About 3/4th of the subjects were malnourished (78.9%, with more (53.7% being under weight than over weight and obese (25.2%. Similarly, more than half (55.1% of the subjects were anemic. Central obesity as indicated by WHtR & WC was 21.6% and 9.0% respectively. The burden of sub optimal blood pressure was very high (26.3% among adolescents (Pre hypertension 13.7% and hypertension 12.6%. Hence, malnutrition along with anemia and high blood pressure were significant problems in private schools. Schools being the best setting to approach adolescents and parents, multi disciplinary programs should be part of school policies to prevent and manage triple burden of malnutrition and its adverse consequences among the adolescents from private schools.

    As noted elsewhere in this report, a central goal of the Extended Duration Orbiter Medical Project (EDOMP) was to ensure that cardiovascular and muscle function were adequate to perform an emergency egress after 16 days of spaceflight. The goals of the Regulatory Physiology component of the EDOMP were to identify and subsequently ameliorate those biochemical and nutritional factors that deplete physiological reserves or increase risk for disease, and to facilitate the development of effective muscle, exercise, and cardiovascular countermeasures. The component investigations designed to meet these goals focused on biochemical and physiological aspects of nutrition and metabolism, the risk of renal (kidney) stone formation, gastrointestinal function, and sleep in space. Investigations involved both ground-based protocols to validate proposed methods and flight studies to test those methods. Two hardware tests were also completed.

    Background: Since type-2 diabetes is the most common chronic disease among Iranian female adolescents, we applied theory of planned behavior to examine the effect of training to intention to preventative nutritional behaviors for type-2 diabetes among female adolescents. Methods: In this experimental study 200 (11-14 year old) girls from 8 schools of Tehran city (100 in each intervention and control group) were recruited based on cluster sampling method during two stages. For intervention group, an educational program was designed based on the theory of planned behavior and presented in 6 workshop sessions to prevent type-2 diabetes. The data were collected before and two months after the workshops using a valid and reliable (α=0.72 and r=0.80) authormade questionnaire based on Ajzens TPB questionnaire manual. The data were analyzed using t-test, chi-square test and analysis of covariance. Results: Findings indicate that the two groups were homogeneous regarding the demographic characteristics before education, but the mean score of the theory components (attitudes, subjective norms, perceived behavioral control, and intention) was higher in the control group. Also, results showed all of the theory components significantly increased after the education in the intervention group (p=0.000). Conclusion: Training based on the theory of planned behavior enhances the intention to adherence preventative nutritional behaviors for type-2 diabetes among the studied female adolescents.

Fifth instar larvae reared on Shin Ichinose showed the highest efficiency of conversion of digested food and efficiency of conversion of ingested food (3.82±0.16% and 3.11±0.07%, respectively. Approximate digestibility values of the fourth instar larvae were highest (95.23±0.73% and lowest (91.77±1.45% on Kenmochi and Shin Ichinose, respectively. The fifth instar larvae fed on Kenmochi had the highest consumption index (4.6±0.73 and lowest relative growth rate (0.03±0.10, respectively. Our results showed that the highest protease activity in optimal pH was on Malalii variety (0.97 U/mg and the lowest was on Kenmochi (0.75 U/mg. In addition, the highest amylase activity in optimal pH was on Mahalii (0.17 U/mg and lowest on Kenmochi (0.103 U/mg. Specific proteolytic analysis showed that larvae feeding on Mahalii had the highest activity of trypsin and elastase (2.30 and 2.13 U/mg, respectively. This research showed that plasticity in food utilization and enzyme activity is functionally relevant to host plant cultivars. The results of nutritional indices and activity of digestive enzymes indicated that Kenmochi was an unsuitable host for feeding of Glyphodes pyloalis.

    Full Text Available The study investigated the relationship between body image dissatisfaction, nutritional status, and eating attitudes in adolescents from a small town of the interior of São Paulo State. A total of 278 adolescents (106 boys and 172 girls aged between 15 and 18 years had completed measures of body image dissatisfaction through the Figure Rating Scale and eating attitudes by the Eating Attitudes Test (EAT-26 and had their weight and height measured. Girls related more dissatisfaction and abnormal eating behavior than boys and, in both genders the abnormal eating attitudes tend to increase with increasing dissatisfaction. Moreover, dissatisfaction was higher between those individuals classified as overweight and obesity. These results demonstrated that body image dissatisfaction and inappropriate eating behaviors afflict boys and girls even from small cities in developing countries, highlighting the need to undertake epidemiological studies to early recognition of populations at risk of developing eating disorders.

  10. Physiological Regulation of Gut Peptide Hormone (PYY) Levels by Age, Sex, Hormonal and Nutritional Status in Rats

    International Nuclear Information System (INIS)

    Peptide YY hormone (PYY) was recently appreciated as an important gut hormonal regulator of appetite. PYY is produced by the gut and released into the circulation after food intake and is found to decrease appetite. The main form of PYY, both stored and circulated, is PYY(3-36), the N-terminal truncated form of the full length peptide so, peripheral injections of PYY(3-36) in rats inhibit food intake in experimental animals as well as in lean and obese human subjects. Also, this hormone has been suggested to be an attractive therapeutic option for obesity. PYY levels are influenced by age and the highest hormone level is achieved in early postnatal life (day 30) and is decreased thereafter. PYY levels were also dependent on thyroid hormone status and being decreased in hyperthyroid rats. The PYY levels observed in acute and chronic food restricted rats indicated that, in situations of decreased energy intake, the lower PYY levels could serve to regulate central pathways and facilitate food intake. Contrary, in pregnant rats, PYY levels were enhanced at late gestation. The aim of this study was to assess the influence of age, sex, thyroid status, pregnancy and food restriction on PYY levels in rats. The underling mechanisms through which PYY levels alternated as a result of sex, age, pregnancy, thyroidal and nutritional status were discussed in the light of recent research outcomes

    Full Text Available Abraham Maslow (1908 – 1970 has set up a hierarchy of five levels of basic needs. Of those that are considered to be basic physiological needs hunger, thirst as well as bodily comforts are considered to be the most important. Physiological needs are the strongest needs because if a person were deprived on all needs it is these physiological needs that would take the highest priority. As food is characterized as a basic need, we should have a special view on our daily food and our handling of it. Most people do not act careful with their daily intake of food. In the last decades, the increases of nutrition-associated diseases such as overweight and obesity and on the other hand underweight have been recorded. From a life-span approach, the problem has its offset point in the early age of development, namely in children and adolescents. Malnutrition, overweight and obesity limit children’s personal quality of life in terms of unhappiness with their own body, opposition or even rejection in peer group communication and general difficulties in day-to-day social interaction. A close connection between physical stature and the development of a negative self-concept and a low self-esteem is postulated.

    Full Text Available Asthma during adolescence can induce social, psychological, and behavioral problems. We examined the impact of asthma and other allergic diseases on psychological symptoms and health risk behaviors among South Korean adolescents.In this population-based cross-sectional study, 3192 adolescents (10-18 years of age participating in the 2008-2011 Korean National Health and Nutrition Examination Survey were enrolled. Psychological problems associated with clinically diagnosed asthma, allergic rhinitis, and atopic dermatitis were assessed using questionnaires and surveys. Data was analyzed using logistic regression to determine the association of depression with allergic disease while controlling for age, sex, body mass index, smoking experience, and alcohol use.Asthma and atopic dermatitis were associated with a higher prevalence of depression (17.2% and 13%, respectively. After adjusting for the covariates, asthma patients were approximately two times as likely to have depression as non-allergic participants (odds ratio, 1.81; 95% confidence interval, 1.22-2.68. Psychosocial stress significantly increased in the following order: no allergy, any allergy without asthma, asthma only, and asthma with any allergy (p for linear trend = 0.01. The asthma without other allergies group showed the highest prevalence of cigarette smoking (p = 0.007.In this study, asthma with or without other allergies was significantly related to increases in depression, psychosocial stress, and smoking experience. Thus, care should be taken to adjust treatment to account for the psychological symptoms and health risk behaviors common among asthmatic adolescents.

    2016-01-01

    The purpose of this review is to draw attention to the limited information available on food intake (FI) control in children and adolescents 7-17 y of age, which is essential for developing food policies and guidelines in this population. Although environmental factors have been the overwhelming focus of research on the causative factors of obesity, research focusing on the physiologic control of appetite in children and adolescents is a neglected area of research. To present this message, a review of FI regulation and the role of food and food components in signaling processes are followed by an examination of the role of hormones during puberty in intake regulation. To examine the interaction of environment and physiology on FI regulation, the effects of exercise, television programs, and food advertisements are discussed. In conclusion, although limited, this literature review supports a need for children and adolescents to be a greater focus of research that would lead to sound nutrition policies and actions to reduce chronic disease. A focus on the environment must be balanced with an understanding of physiologic and behavioral changes associated with this age group. PMID:26773031

    Vineyard sandy acid soils from South Brazil have experienced heavy metal contamination due to replacement of copper (Cu)-based by zinc (Zn)-based products to control foliar diseases. Thus, we evaluate physiological and nutritional status of black oat (Avena strigosa Schreb.), a common interrow crop in vineyards from this region. Soil was collected in a natural field from Santana do Livramento, in Rio Grande do Sul, the southernmost state of Brazil. Black oat was cultivated for 30 days in a greenhouse with application of 0, 30, and 60 mg Cu kg(-1) combined with 0, 15, 30, 60, 120, and 180 mg Zn kg(-1). After the trial period, dry matter accumulation of roots and shoots, Cu and Zn contents in roots and shoots, chlorophyll a fluorescence, photosynthetic pigments and catalase (CAT, EC 1.11.1.6) and peroxidase (POD, EC 1.11.1.7) activity were determined. Cu and Zn toxicity was evidenced by the decrease in plant growth of black oat as well as by the decrease of photochemical efficiency associated with the decrease in photosynthetic pigment content, especially with the highest doses of Cu and Zn. Furthermore, the activity of antioxidant enzymes (CAT and POD) was increased in intermediate doses of Zn, indicating the activation of the antioxidant system, but the stress condition in treatments with high levels of Cu and Zn was not reversed.

    Full Text Available Carbon dioxide enrichment and nutritional improvement can increase photosynthesis and growth of different crops. The aim of the present study was to assess interaction effects of CO2 enrichment and fertilizer on physiological characteristics and lemon balm essential oil. Experimental units were composed of CO2 at 380, 700, and 1050 ppm with and without manure and N fertilizer application. A continuous increasing trend of individual plant leaf area, total dry weight accumulation and relative growth ratio were recorded with CO2 enrichment. When CO2 was elevated from 380 to 1050 ppm, the values of height (24.3%, SPAD reading (2.7%, essential oil yield (26.3% and final yield (65.3% were increased, unlike, stomatal conductance (35.2% and essential oil percentage (53% were decreased. The highest and the lowest values (except for oil percentage were obtained under N and no fertilizer application, respectively. Except for SPAD, interaction between CO2 enrichment and each fertilizer on all measured characteristics had a significant effect, so that CO2 effect was intensified by applying each fertilizer. Therefore, it can be concluded that when temperature increase caused by rising CO2 is not considered or there is not a limitation for resources, CO2 enrichment will improve lemon balm biomass and essential oil yield.

    We investigate dietary intake and lifestyle patterns of atopic children and adolescents (N = 539) by obesity level using a national survey of South Korea. Intakes of calcium, iron, and vitamin C in the underweight group were less than those of other groups. The frequency of drinking milk of the overweight group was higher than that of the normal weight group. Majority of the subjects had not applied nutrition labeling in food choices, had no experience of nutrition education, and were vitamin D deficient. In conclusion, most of the atopic subjects had little knowledge of nutrition and were vitamin D deficient. PMID:26595187

  18. Fluctuation phenomena

    International Nuclear Information System (INIS)

    Fluctuation phenomena are the ''tip of the iceberg'' revealing the existence, behind even the most quiescent appearing macroscopic states, of an underlying world of agitated, ever-changing microscopic processes. While the presence of these fluctuations can be ignored in some cases, e.g. if one is satisfied with purely thermostatic description of systems in equilibrium, they are central to the understanding of other phenomena, e.g. the nucleation of a new phase following the quenching of a system into the co-existence region. This volume contains a collection of review articles, written by experts in the field, on the subject of fluctuation phenomena. Some of the articles are of a very general nature discussing the modern mathematical formulation of the problems involved, while other articles deal with specific topics such as kinetics of phase transitions and conductivity in solids.

    Full Text Available Com o objetivo de avaliar o efeito do equilíbrio nutricional sobre a incidência de distúrbios fisiológicos em manga 'Tommy Atkins' cultivada no Vale do São Francisco, realizou-se um ensaio com frutos coletados no estádio de maturação fisiológica, classificados em frutos sem sintomas e com sintomas de distúrbio fisiológico. Os frutos das duas classes foram separados em casca, polpa e caroço, e levados para secagem em estufa a 65 °C. Este material foi submetido a mineralização para a determinação das concentrações de N, K, Ca, Mg e B. Antes da desidratação, uma parte da polpa foi separada para as determinações do teor de sólidos solúveis totais (SST e da acidez total titulável (ATT. Os resultados permitem concluir que, tanto as concentrações elevadas de Ca e Mg, como as baixas relações N/Ca e K/Ca, tanto na polpa quanto na casca, foram eficientes na prevenção de distúrbios fisiológicos nos frutos de mangueira; a concentração de nutrientes obtida na casca pode refletir melhor a condição da fisiopatia do que a concentração dos nutrientes na polpa dos frutos; os valores de SST e a relação SST/ATT determinada nos frutos com sintomas foram muito mais elevados do que nos frutos sem sintomas, devido a uma sobrematuração desordenada dos tecidos da polpa.With the objective of evaluating the effect of the nutritional balance on the incidence of physiological disorders in mango cv. Tommy Atkins, grown in São Francisco River Valley, a trial was carried out with fruits harvested at physiological ripening stage, classified as fruits without and with physiological disorder symptoms. From all of them, skin, flesh and pit were separated and dried in a stove at 65ºC. This material was mineralized in order to determine N, K, Ca, Mg and B contents. Before dehydration, part of the flesh was taken for estimation of the total soluble solids (TSS and total titrable acidity (TTA. The results allow to conclude that: high

    Full Text Available Introduction: Nutrition status prior to pregnancy is of vital importance. Inadequate iron stores bef ore conception is a major cause of iron deficiency.The primary objective of this research was to estimate the prevalence of anaemia and the secondary objective was to assess various epidemiological factors associated with anaemia. Methods: A community based, cross - sectional study was carried among 207 unmarried adolescent girls between 10 to 19 years, residing in urban field practice area of tertiary care hospital in Mumbai for one year. All study participants social demographic profile, diet history was collected. Findings of clinical examination, height and weight was recorded. Blood and stools samples were collected after obtaining verbal consent from their parents. Univariate and binary logistic regression analysis was done using SPSS 11.5 version. Results: The overall prevalence of anaemia was 78.3%. Prevalence of mild, moderate and severe anaemia was 64.2%, 36.2% and 0.6% respectively. Study participants with BMI <18.5 Kg/M 2 had significantly higher prevalence of anaemia. 88.9% had no knowledge regarding anaemia. In logistic regression analysis body mass index, per capita income and intestinal parasites in stool were the variables independently associated with anaemia. Conclusions: The high prevalence of anaemia among adolescent girls indicates need for additional nutritional support, iron folic acid supplementation including prevention and control of worm infestation in urban communities. It would be desirable that action for improvement is initiated right at the adolescent stage, thereby ensuring adequate body stores of iron even before they marry and become pregnant.

    Full Text Available Abstract Background Little research has given consideration to how people's weight control behaviors may moderate the relationships between nutrition and body mass index (BMI in large cross-sectional studies. The objective of the current study is to determine how attempts to lose weight confound the relationships between nutrition behaviors and BMI among a population of predominately overweight adolescents. Methods Data were drawn from the baseline measurements of the Pacific OPIC (Obesity Prevention In Communities. Participants included approximately 3500 high school students in New Zealand. Students in the sample primarily identified as a Pacific Island ethnicity (57% and the mean age for participants was 14.8 years. Participants completed a questionnaire about nutrition and physical activity patterns and were weighed and measured for height. Results In our sample, 57% of students were overweight/obese, with the highest prevalence among Pacific Island students (71%. Approximately 50% of students were currently trying to lose weight, and this was more common among females, Pacific Island students and overweight/obese students. Examination of the nutritional correlates of BMI in the total population found inverse relationships between BMI and consumption of high-fat/high-sugar foods and positive relationships between BMI and eating 5 or more fruits and vegetables a day (all significant after controlling for age, sex, and ethnicity. For example, students who drank the most soft drinks or ate fruit and vegetables infrequently had the lowest mean BMI. Students' attempts to change their weight significantly moderated the relationships between most nutritional behaviors and BMI. In most cases, among students not trying to change their weight, expected relationships were observed; among students trying to lose weight, unexpected or no relationships were observed. Conclusion Our findings suggest that among this population of predominately overweight

    Full Text Available Based on data from the 2010–2011 Korean National Health and Nutrition Examination Survey, we investigated correlations between micronutrients in the diet of family members and the possible risk factors for children and adolescents consuming an inadequate diet. We examined two-generation households with children aged 2–18 years. The quality of the family diet with regard to the following nine nutrients (protein, calcium, phosphorous, iron, vitamin A, vitamin B1, vitamin B2, niacin, and vitamin C was assessed based on the Index of Nutritional Quality. Correlations between quality of diet and selected variables were analyzed using the Statistical Analysis for Genetic Epidemiology software, and those between diet quality and potential risk factors for poor diet in offspring were analyzed using multinomial logistic regression. Overall, calcium was the most commonly under-consumed micronutrient. More than half of sons and daughters showed insufficient vitamin A, vitamin C, and iron intake, and both mothers and fathers showed insufficiency with respect to vitamin A, vitamin B2, and vitamin C. The correlation between a poor diet in parents and that in offspring was 0.17 (p < 0.0001, and this correlation coefficient was higher between mothers and offspring than between fathers and offspring. Additionally, eating breakfast provided a significant protective effect against the risk of poor nutrition in offspring, even after adjusting for covariates. Our results add to evidence indicating that children should be encouraged to eat breakfast to improve the quality of their diet.

    Bacteria (Pseudomonas sp. and Bacillus sp.) and/or the arbuscular mycorrhizal (AM) fungus Rhizophagus intraradices were able to improve growth, physiological and biochemical characteristics of four Sulla carnosa Desf. provenances (Sidi khlif, Thelja, Kalbia and Kerker) from Tunisia under both saline and non-saline conditions. S. carnosa is a salt-tolerant legume plant, native from North Africa. The intrinsic bacterial characteristics evidenced the fitness of these bacteria to support salt stress and to stimulate plant growth. Bacillus sp. produced more indol acetic acid (IAA) than Pseudomonas sp. and showed a great surviving capacity under salt conditions supporting its capacity to improve plant growth under stress conditions. The microorganisms applied also have a different potential to increase the nutritional and related plant growth parameters. It is noticeable that some provenances reached the highest level of growth when inoculated with Bacillus sp. in Sidi khlif or by Bacillus plus AMF in Kalbia, which increased shoot by 318% and root by 774%. In contrast, in Thelja and Kerker the impact of the test microorganisms was mainly evidenced at increasing nutritional and physiological functions. Salinity reduced some growth and physiological variables as stomatal conductance, photosynthetic pigments and photosynthetic efficiency and increased electrolyte leakage. However, the microbial inoculants compensated these detrimental effects in a degree depending on the S. carnosa provenance. These microorganisms also orchestrate antioxidant activities involved in adaptative responses in S. carnosa provenances. The intrinsic ability of inoculants allow us to select the provenance/microorganism combination which maximizes S. carnosa growth, nutrition and physiological/biochemical responses under salt and non-salt conditions. The results obtained support that the target microbial inocula are beneficial for the ecological stability if this Mediterranean legume. PMID:27393918

    Full Text Available INTRODUCTION: Brazil has been called a nation in nutrition transitional because of recent increases in the prevalence of obesity and related chronic diseases. With overweight conditions already prevalent among middle-income populations, there exists a need to identify factors that influence nutrition behavior within this group. OBJECTIVE: To address this subject, a research study was implemented among middle-class adolescents attending a large private secondary school in Manaus, Amazonas, Brazil. The study determined the availability and accessibility of snack foods as well as subjects’ attitudes and preferences towards, and the influence of family and friends on healthy (high-nutrient density snack choices. METHODS: The 4-stage process included: (a a nutrition expert focus group discussion that reported local nutrition problems in general and factors related to adolescent nutrition, (b an adolescent pilot survey (n=63 that solicited information about snacking preferences and habits as well as resources for nutrition information and snack money; (c a survey of various area food market sources to determine the availability and accessibility of high nutrient density snacks; and (d a follow-up adolescent survey (n=55 that measured snack food preferences and perceptions about their cost and availability. RESULTS: Results included the finding that, although affordable high nutrient density snacks were available, preferences for low nutrient density snacks prevailed. The adolescents were reportedly more likely to be influenced by and obtain nutrition information from family members than friends. CONCLUSION: From study results it is apparent that a focus on food availability will not automatically result in proper nutritional practices among adolescents. This fact and the parental influence detected are evidence of a need to involve adolescents and their parents in nutrition education campaigns to improve adolescent snack food choices.INTRODUÇÃO: O

  18. Flow phenomena

    International Nuclear Information System (INIS)

    Few aspects of magnetic resonance (MR) imaging are as potentially confusing as the effect of motion on the MR image. While the MR image is anatomically similar to the image produced by CT, the MR appearance of flowing blood has no correlate in CT. Flowing blood can appear bright or dark, depending on the velocity and direction of flow. To a first approximation, rapidly flowing blood appears dark ('flow void') and slowly flowing blood appears bright. This phenomenon is illustrated. This appearance is markedly influenced by factors related to the imaging sequence and to the MR imager itself. The signal from flowing blood depends on the position of the slice relative to the rest of the multislice imaging volume. It depends on the repetition time TR, the echo-delay time TE, the echo number, and the slice thickness. In fast scanning techniques with short repetition times, gradient echoes, and flip angles less than 90 degrees, flow has a different appearance than on standard 90 degrees/180 degrees spin-echo images. The principles which affect the appearance of flowing blood also affect the appearance of flowing cerebrospinal fluid (CSF). Examples of CSF flow phenomena are given

    Childhood overweight and obesity are major health problems with immediate and long-term consequences of staggering magnitude. Despite this, there are few preventive and therapeutic strategies of proven effectiveness available to public health and clinical practitioners. Accruing such evidence is currently and appropriately a health policy priority, but there is an urgent need to intervene even before comprehensive solutions are fully established. The aim of this Clinical Report on Overweight Children and Adolescents is to present information on current understanding of pathogenesis and treatment of overweight and obesity. We report on the epidemiology, molecular biology and medical conditions associated with overweight; on dietary, exercise, behavioral, pharmacological and surgical treatments; and on the primary prevention of overweight in children and adolescents.

    2016-01-28

    Using data from the National Health and Nutrition Examination Survey (NHANES) 2003-2012, we investigated the prevalence and characteristics of under- and over-reporting of energy intake (EI) among 14 044 US children and adolescents aged 2-19 years. For the assessment of EI, two 24-h dietary recalls were conducted with the use of the US Department of Agriculture Automated Multiple-Pass Method. Under-, plausible and over-reporters of EI were identified using two methods: based on the 95 % confidence limits (1) for agreement between the ratio of EI:BMR and a physical activity level for sedentary lifestyle (1·55) and (2) of the expected ratio of EI:estimated energy requirement (EER) of 1·0. BMR was calculated using Schofield's equations. EER was calculated using equations from the US Dietary Reference Intakes, assuming 'low active' level of physical activity. The risk of being an under- or over-reporter compared with a plausible reporter was analysed using multiple logistic regression. Percentages of under-, plausible and over-reporters were 13·1, 81·5 and 5·4 %, respectively, based on EI:BMR and 18·8, 72·3 and 8·8 %, respectively, based on EI:EER. Under-reporting was associated with older age, non-Hispanic blacks (compared with non-Hispanic whites) and overweight and obesity (compared with normal weight). Over-reporting was associated with younger age, lower family poverty income ratio, normal weight and the first survey cycle. Similar findings were obtained when analysing only the first 24-h recall data from NHANES 1999-2012 (n 22 949). In conclusion, we found that EI misreporting remains prevalent and differential in US children and adolescents. PMID:26525591

    Adolescence is a phase of rapid growth and development during which physical, physiological and behavioural changes occur. They constitute more than 1.2 billion worldwide, and about 21% of Indian population. Morbidity and mortality occurring in this age group is mostly due to preventable causes. Young and growing children have poor knowledge and lack of awareness about physical and psychological changes that occurs during adolescence and the ill health affecting them. Existing Adolescent health programmes focus on rendering services like immunization, health education for sexual and reproductive health, nutritional education and supplementation, anemia control measures and counseling. Adolescent health programmes are fragmentary at present and there is no comprehensive programme addressing all the needs of adolescents. Access and availability of health care services are severely limited. Lack of accurate information, absence of proper guidance, parent's ignorance, lack of skills and insufficient services from health care delivery system are the major barriers. Interventions should focus on providing psychological and mental health services and behaviour change communication towards leading a healthy lifestyle, restricting advertisement related to junk food products, awareness creation about reproductive and sexual health, educating parents to prevent early marriage, teenage pregnancy and to counsel their children on nutrition and reproductive health. Universal coverage of Adolescent friendly clinics is highly recommended. To be cost effective, all health services addressing adolescent should come under single programme. This review is intended to create awareness among the stakeholders about the importance of strengthening adolescent health services in order to meet their felt needs. PMID:25964884

    Recently, public health messaging has included having more family meals and involving young adolescents (YAs) with meal preparation to improve healthful diets and family dinner frequency (FDF). Kinect-Ed, a motivational nutrition education presentation was created to encourage YAs (grades 6-8) to help with meal preparation and ultimately improve FDF. The purpose of this study was to evaluate the Kinect-Ed presentation, with the goals of the presentation being to improve self-efficacy for cooking (SE), food preparation techniques (TECH), food preparation frequency (PREP), family meal attitudes and behaviours, and ultimately increase FDF. A sample of YAs (n = 219) from Southern Ontario, Canada, completed pre- and postpresentation surveys, measuring FDF, PREP, SE, and TECH. Kinect-Ed successfully improved participants' FDF (p < 0.01), PREP (p < 0.01), SE (p < 0.01), and TECH (<0.01). Overall, goals of the presentation were met. Encouraging YAs to help prepare meals and get involved in the kitchen may reduce the time needed from parents to prepare meals, and, in turn, allow more time for frequent family dinners.

    for the dairy producer. In this study we focus on understanding the overall biological phenomena associated with nutritional sub-fertility rather than the underlying multiplicity of physiological interactions (already described in a number of recent studies). These phenomena are important because they...... represent the natural adaptations of the animal for dealing with variations in the nutritional environment. They can also be used to monitor and modulate reproductive performance on-farm. There is an underlying trade-off between two aspects of reproduction: investment in the viability of the current calf....... Both delay further reproductive commitment. The relationship between reproductive performance and; milk production as an index of maternal investment, body fatness as an index of ability to safeguard reproductive investment, and body fat mobilisation as an index of the current nutritional environment...

    2014-11-01

    Dairy cows may suffer events of hypocalcemia and hypomagnesemia, commonly known as milk fever and tetany. Milk fever is characterized by hypocalcemia at parturition as a consequence of a sudden increase in Ca demand and an unavoidable delay in Ca metabolism adaptation. Tetany is due to impaired Mg absorption from the rumen that cannot be compensated by absorptive or excretory adaptation, resulting in a net nutritional shortage of Mg and culminating in hypomagnesemia. Prevention strategies require triggering the activation of Ca gastrointestinal absorption and avoiding factors limiting ruminal Mg absorption. PMID:25245611

  9. Short-lived radionuclides in nutritional physiology. A model study with L-[Me-11C]methionine in the pig

    International Nuclear Information System (INIS)

    1. A 'new' carbon radioisotope, 11C, for use in nutritional studies is presented. It has a 20 min half-life, and decays by positron emission giving annihilation photons of 511 keV energy (Wolf and Redvanly, 1977). Thus repeated studies can be made with short time intervals and the distribution of radioactivity in the experimental animal can be detected externally. 2. 11C was produced with a tandem Van de Graaff accelerator and L-[Me-11C]methionine was synthesized and used in model experiments in the pig. The tracer was administered intravenously through a catheter in the jugular vein of pigs weighing between 40 and 100 kg. In a series of experiments, one pig received a low-methionine diet supplemented with DL-methionine to give three different levels of methionine intake. 3. The radioactivity distribution between liver and muscle was measured as a function of time by external detectors for 2-3h after administration. Blood and exhaled CO2 were sampled and measured for radioactivity. 4. The results indicate that 11C is a useful radionuclide in nutritional studies in intact large domestic animals. (author)

Methods: All the adolescents presenting with various gynaecological problems were evaluated by detailed history taking and thorough clinical examination after taking an informed consent and explaining them our objective. After examination, adolescent girls were given education by means of slide show about menstruation, care during menses, nutritional diet and prevention of anaemia. Results: Majority of adolescents had regular menstrual pattern. Oligomenorrhoea was the most prevalent abnormality of menstrual pattern in these adolescents. 15.58% adolescents had presented with breast problems like mastalgia, lump in breast, etc. Majority of adolescents studied were aware of the physical signs of puberty (77.25% and HIV (74.14%. But very few adolescents were aware of the physiology involved in menstruation. Around half of all the adolescents were seen to follow proper menstrual hygiene. Conclusions: Healthy adolescence, the need of the hour. [Int J Reprod Contracept Obstet Gynecol 2014; 3(4.000: 1010-1014

  12. A study of the physiological changes and the nutritional qualities of irradiated apples and the effect of irradiation on apples stored at room temperature

    International Nuclear Information System (INIS)

    The effects of γ-irradiation on the metabolism and nutritional qualities of Golden Delicious apples and on the lethality of pathogenic fungi have been studied. The storage effect of irradiation on apples at room temperature has been observed. Results showed that the respiratory intensity of irradiated apple at 0.3-0.5 kGy was near or lower than that of unirradiated apple after 15 days irradiation. The amount of ethylene release was obviously inhibited when fruits were irradiated with 0.3-0.7 kGy. The flesh firmness of apples irradiated with 0.3-0.9 kGy was higher than that of unirradiated apple with increased storage time. The negative correlations between the flesh firmness and the activities of pectinesterase (PE), polygalacturonase (PG) were observed when the dosage was lower than 1.5 kGy. The 2.0 kGy irradiation damaged the ultrastructure of cells, induced the softening of apple. When apples were irradiated with 0.7-2.0 kGy, the contents of 4 important volatile components of apple would be decreased. However, this dose had no effects on the pure chemicals. Studies showed that there was no significant effect of irradiation with 0.3-2.0 kGy on the nutritional qualities of apples and this dose range could effectively control the verticillate pathogenic fungi. The result of storage experiment showed that rotting of fruits decreased by 0.3-0.9 kGy irradiation. (author)

    Matani, Ayumu

    Nonlinear electrophysiological synchronization phenomena in the brain, such as event-related (de)synchronization, long distance synchronization, and phase-reset, have received much attention in neuroscience over the last decade. These phenomena contain more electrical than physiological keywords and actually require electrical techniques to capture with electroencephalography (EEG). For instance, epoch filters, which have just recently been proposed, allow us to investigate such phenomena. Moreover, epoch filters are still developing and would hopefully generate a new paradigm in neuroscience from an electrical engineering viewpoint. Consequently, electrical engineers could be interested in EEG once again or from now on.

    A study was conducted to assess the impact of heat and nutritional stress simultaneously on the adaptive capability as indicated by behavioral and physiological responses, plasma heat shock protein 70 (HSP70) level, and peripheral blood mononuclear cells (PBMC) HSP70 gene expression in goats. Twenty-four adult Osmanabadi bucks (average body weight (BW) 16.0 kg) were used in the present study. The bucks were divided into four groups viz., C (n = 6; control), HS (n = 6; heat stress), NS (n = 6; nutritional stress), and CS (n = 6; combined stress). The study was conducted for a period of 45 days. C and HS bucks had ad libitum access to their feed while NS and CS bucks were under restricted feed (30 % intake of C bucks) to induce nutritional stress. The HS and CS bucks were exposed to solar radiation for 6 h a day between 10:00 a.m. and 4:00 p.m. to induce heat stress. The data was analyzed using repeated measures analysis of variance. The standing time differed significantly (P groups (C and HS) and restricted feeding groups (NS and CS). The highest (P group while the lowest in the C and HS groups. The highest (P group. Water intake recorded was significantly (P groups. The highest respiration rate (RR), pulse rate (PR), and rectal temperature (RT) during the afternoon were also recorded in the CS group. Further, skin temperature of the head, flank, and scrotum during the afternoon was also higher (P group. In addition, both plasma HSP70 concentration and PBMC HSP70 messenger RNA (mRNA) transcript expression were also significantly (P group. It can be concluded from this study that when two stressors occur simultaneously, they may have severe impact on adaptive capabilities of Osmanabadi bucks as compared to that would occur individually. Further, the study indicated that lying time, drinking frequency, RR, RT, plasma HSP70, and PBMC HSP70 gene expression may act as ideal biological markers for assessing the impact of CS on adaptive capabilities in bucks.

Con ello se pretende contribuir a mejorar el estado de salud de la población española del nuevo milenio.Background: Adolescence is a decisive period in human life due to the multiple physiological and psychological changes that take place. These changes will condition both nutritional requirements and eating/physical activity behavior. It has been demonstrated that these "adolescence" factors are of significant influence in health status during adult life. Due to its importance and adequate development the project has been granted by the Fondo de Investigación Sanitaria of the Institute of Health Carlos III. Objective: To develop a methodology to evaluate the health and nutritional status of a representative population of Spanish adolescents. Specific attention is paid to three specific health problems: obesity, anorexia nervosa/ bulimia, dislipidemia. Methodology: The following magnitudes will be studied: 1 dietary intake, food habits and nutrition knowledge; 2 daily physical activity and personal approach; 3 physical condition; 4 anthropometry and body composition; 5 hematobiochemical study: plasma lipid phenotypic and metabolic profile, blood cell counts; 6 genotipic profile of cardiovascular risk lipid factors; 7 immune function profile related to nutritional status; 8 psychological profile. Conclusion: This project includes the co-ordinate activity of five Spanish centers of five different cities (Granada, Madrid, Murcia, Santander, Zaragoza. Each center is specialized in a specific area and will be responsible for the corresponding part of the study. From the data obtained, we will elaborate a specific intervention program in order to improve nutrition and neutralize the risk for nutritional related problems in adolescence. By this, we will contribute to improve the health status of the Spanish population in the new millennium.

    Efforts to optimize the diet in terms of prevention and treatment of obesity aim at long-term adaptation and reduction of energy intake according to age and physiological requirements while preserving the nutrient density with consideration of individual food preferences.As the nutritional habits of the average Austrian people are unfavorable for obesity prevention there is a clear need for action. Women are "disadvantaged" in weight control compared to men in terms of physiological conditions-and are confronted with specific needs during life course (e.g. pregnancy), whereas the average man or male adolescents present "unhealthier" behaviors and attitudes and are (still) less interested on nutrition or weight control.To achieve better nutrition a target-group specific, gender-sensitive guidance of the individual is needed, starting with pregnant women, but also habitat-oriented interventions for improved nutrition offers, which have to be sustainably assured through the support of a relevant legal and social framework.

    Nutrition is one of the most important factors affecting pubertal development. Puberty entails a progressive nonlinear process starting from prepubescent to full sexual maturity through the interaction and cooperation of biological, physical, and psychological changes. Consuming an adequate and balanced healthy diet during all phases of growth (infancy, childhood and puberty) appears necessary both for proper growth and normal pubertal development. Girls begin puberty at an earlier age compared to past decades. Excessive eating of many processed, high-fat foods, may be the cause of this phenomenon. Overweight or obese children are more likely to enter puberty early. Some evidence suggests that obesity can accelerate the onset of puberty in girls and may delay the onset of puberty in boys. Moreover, the progression of puberty is affected by nutrition. On the other hand, puberty triggers a growth spurt, which increases nutritional needs including macro and micronutrients. Increased caloric, protein, iron, calcium, zinc and folate needs have to be provided during this critical period of rapid growth. Severe primary or secondary malnutrition also can delay the onset and progression of puberty. The higher incidence of anorexia nervosa and bulimia in adolescents imposes a nutritional risk on pubertal development. Moreover, many environmental endocrine disruptors (EDs) have been identified that can significantly impair the normal course of puberty. This mini-review sums up some important findings in this important complex that link nutrition and pubertal development. PMID:25538876

    Adolescence is a phase of human development which is marked by a high vulnerability due to the ongoing psycho-physiological transformations. The regulation of the self-esteem is especially in danger in youngsters who went into adolescence with a marked burden of conflicts or who lived in families with disturbed intrafamilial dynamics. To be present as a partner and not to find the solutions for the adolescents' conflicts, to accept their questioning of what is established and to recognize their movements of reconciliation are the quite complex demands put on to the world of the adults. Adolescents urge us to a review of our own adolescence, to a balancing of hate and love, openness and rigidity, and to dialectic movements between disintegration and reintegration as well as between the generations. Any help, be it on the physical, the social or the psychic level, should be directed toward a restitution of the intrapsychic, intrafamilial or intergenerational balance; sociocultural factors have also always to be respected. The helpers--especially in a culture with rapid change--are often confronted with their own adolescence, which took place a generation before and mostly under totally different conditions.

    The term health behaviour combines both health-promoting and health-risk components. In this study, the health behaviour of children and adolescents in Thuringia is analysed. The database was a representative subsample of the federal state module Thuringia, which was conducted by the Robert Koch Institute as part of the German Health Interview and Examination Survey for Children and Adolescents (KiGGS) wave 1 (2010-2012; n = 4,096; 3-17 years). Health behaviour was described based on nine indicators: fruit and vegetable consumption, soft drink consumption, breakfast at home, physical activity, sport, swimming ability, alcohol consumption, smoking and water pipe consumption (shisha smoking). Prevalence and mean values with 95 % confidence intervals were reported, and based on logistic or linear regression, the significance of the group differences was examined. The results show that 43.4 % of children and adolescents in Thuringia ate fruits and vegetables daily, 44.5 % consumed soft drinks less than once a week, and 67.9 % had breakfast at home every weekday. In addition, 31.0 % of children and adolescents in Thuringia were physically active at least 60 min a day, 69.8 % did sports for at least 2 h a week, and 81.5 % can swim. Additionally, 15.9 % of adolescents in Thuringia had hazardous alcohol consumption, 14.4 % currently smoked, and 20.0 % smoked a water pipe. Differences existed with regard to gender, age, socio-economic status (SES) of the family and residence (urban/rural). In summary, many of the children and adolescents in Thuringia demonstrate relatively positive health behaviour. However, the results also indicate groups at higher risk of unhealthy behaviour, such as children and adolescents from families with low SES. PMID:27351434

    Complex fission phenomena can be studied in a unified way. Very general reflection asymmetrical equilibrium (saddle-point) nuclear shapes, may be obtained by solving an integro-differential equation without being necessary to specify a certain parametrization. The mass asymmetry in cold fission phenomena can be explained as the result of adding a phenomenological shell correction to the liquid drop model deformation energy. Applications to binary, ternary, and quaternary fission are outlined. Predictions of two alpha accompanied fission are experimentally confirmed.

    Full Text Available Abstract Background The increase in the burden of chronic diseases linked to the nutrition transition and associated dietary and lifestyle changes is of growing concern in south and east Mediterranean countries and adolescents are at the forefront of these changes. This study assessed dietary intake and association with socio-economic factors and health outcomes among adolescents in Tunisia. Methods Cross-sectional survey (year 2005; 1019 subjects 15-19 y. from a clustered random sample. Dietary intake was assessed by a validated semi-quantitative frequency questionnaire (134 items as was physical activity; the Diet Quality Index International measured diet quality; dietary patterns were derived by multiple correspondence analysis from intakes of 43 food groups. Body Mass Index (BMI ≥85th and 95th percentile defined overweight and obesity. Waist Circumference (WC assessed abdominal fat. High blood pressure was systolic (SBP or diastolic blood pressure (DBP ≥90th of the international reference for 15-17 y., and SBP/DBP ≥120/80 mm Hg for 18-19 y. Results Energy intake levels were quite high, especially for females. The macro-nutrient structure was close to recommendations but only 38% had a satisfactory diet quality. A main traditional to modern dietary gradient, linked to urbanisation and increased economic level, featured an increasing consumption of white bread, dairy products, sugars, added fats and fruits and decreasing consumption of oils, grains, legumes and vegetables; regarding nutrients this modern diet score featured a decreasing relationship with total fat and an increase of calcium intake, but with an increase of energy, sugars and saturated fat, while vitamin C, potassium and fibre decreased. Adjusted for age, energy and physical activity, this modern pattern was associated with increased overweight in males (2nd vs. 1st tertile: Prevalence Odds-Ratio (POR = 4.0[1.7-9.3], 3rd vs. 1st: POR = 3.3[1.3-8.7] and a higher WC

    Despite its contribution to nutrient intake and status, consumption of milk and dairy products by children and adolescents in many countries has waned in recent decades, with a substantial proportion of youth failing to meet intake recommendations. Dairy products remain an important dietary source of multiple micronutrients, including calcium, phosphorus, magnesium, zinc, iodine, potassium, vitamin A, vitamin D, vitamin B12 , and riboflavin (vitamin B2 ). In addition, dairy products provide children with energy, high-quality protein, and essential and nonessential fatty acids. A review of evidence was conducted to evaluate associations between milk or dairy product intake and health outcomes in children and adolescents. Results suggest a neutral or inverse association between consumption of milk and dairy products in children and adolescents and indicators of adiposity, incidence of dental caries, and hypertension. Available data indicate that dairy products are important for linear growth and bone health during childhood. Additional research--in particular, controlled intervention trials and long-term prospective cohort studies--is warranted to better understand how dairy intake affects health outcomes in children and adolescents.

    Ion exchange phenomena involve the population of readily exchangeable ions, the subset of adsorbed solutes that balance the intrinsic surface charge and can be readily replaced by major background electrolyte ions (Sposito, 2008). These phenomena have occupied a central place in soil chemistry research since Way (1850) first showed that potassium uptake by soils resulted in the release of an equal quantity of moles of charge of calcium and magnesium. Ion exchange phenomena are now routinely modeled in studies of soil formation (White et al., 2005), soil reclamation (Kopittke et al., 2006), soil fertilitization (Agbenin and Yakubu, 2006), colloidal dispersion/flocculation (Charlet and Tournassat, 2005), the mechanics of argillaceous media (Gajo and Loret, 2007), aquitard pore water chemistry (Tournassat et al., 2008), and groundwater (Timms and Hendry, 2007; McNab et al., 2009) and contaminant hydrology (Chatterjee et al., 2008; van Oploo et al., 2008; Serrano et al., 2009).

    This book contains the lectures of the second course devoted to bioelectro­ chemistry, held within the framework of the International School of Biophysics. In this course another very large field of bioelectrochemistry, i. e. the field of Membrane Phenomena, was considered, which itself consists of several different, but yet related subfields. Here again, it can be easily stated that it is impossible to give a complete and detailed picture of all membrane phenomena of biological interest in a short course of about one and half week. Therefore the same philosophy, as the one of the first course, was followed, to select a series of lectures at postgraduate level, giving a synthesis of several membrane phenomena chosen among the most'important ones. These lectures should show the large variety of membrane-regulated events occurring in living bodies, and serve as sound interdisciplinary basis to start a special­ ized study of biological phenomena, for which the investigation using the dual approach, physico-che...

  14. Understanding the Psycho-Physiological Implications of Interaction With a Virtual Reality-Based System in Adolescents With Autism: A Feasibility Study.

    Science.gov (United States)

    Kuriakose, Selvia; Lahiri, Uttama

    2015-07-01

    Individuals with Autism are characterized by deficits in socialization and communication. In recent years several assistive technologies, e.g., Virtual Reality (VR), have been investigated to address the socialization deficits in these individuals. Presently available VR-based systems address various aspects of social communication in an isolated manner and without monitoring one's affective state such as, anxiety. However, in conventional observation-based therapy, a therapist adjusts the intervention paradigm by monitoring one's anxiety level. But, often these individuals have an inherent inability to explicitly express their anxiety thereby inducing limitations on conventional techniques. Physiological signals being continuously available and not directly impacted by these communication difficulties can be alternatively used as markers of one's anxiety level. In our research we aim at designing a Virtual-reality bAsed Social-communication Task (VAST) system that can address the various aspects of social communication, e.g., social context, subtle social cues, emotional expression, etc., in a cumulative and structured way. In addition, we augment this with a capability to use one's physiological signals as markers of one's anxiety level. In our preliminary feasibility study we investigate the potential of VAST to cause variations in one's performance and anxiety level that can be mapped from one's physiological indices.

    Full Text Available Introduction. The prevalence of chronic diseases in adolescence is constantly increasing, especially in the last two decades. Adolescence is a period of important changes: body growth and development, sexual development, development of cognitive abilities, change in family relations and between peers, formation of personal identity and personal system of values, making decisions on future occupation etc. Chronic diseases in adolescence. Chronic disorders affect all development issues and represent an additional burden for adolescents. The interaction between chronic disorders and various development issues is complex and two-way: the disease may affect development, and development may affect the disease. Developmental, psychosocial and family factors are of great importance in the treatment of adolescents with chronic disorders. Chronic disorders affect all aspects of adolescent life, including relations with peers, school, nutrition, learning, traveling, entertainment, choice of occupation, plans for the future. Physicians should keep in mind that chronic diseases and their treatment represent only one aspect of person's life. Adolescents with chronic diseases have other needs as well, personal priorities, social roles and they expect these needs to be recognized and respected. Adolescent health care should be adjusted to the life style of adolescents.

    A growing body of scientific and epidemiological evidence indicates that diet and health are related: diet may be a risk factor or have potential protective effects. As a consequence, the focus of nutrition research has experienced a shift towards qualitative aspects of diet which could influence chronic disease, longevity, quality of life and physical and cognitive performance, leading to the development of Community Nutrition. The main undertakings in a Community Nutrition Unit are related to the identification, assessment and monitoring of nutrition problems at the community level and to planning, design, implementation and evaluation of nutrition intervention programs. Such programs combine a number of suitable strategies in a whole population approach, a high risk approach or an approach targeted at specific population groups, and are implemented in different settings, such as the work place, schools or community organizations. Community nutrition interventions aim to gradually achieve change in eating patterns towards a healthier profile. Community Nutrition programs require the use of a combination of strategies and a working group of people from different backgrounds. Many factors influence the nutritional status of an individual or a population. In order to gain effective work output, sound understanding of these patterns and a practical surveillance system are required. PMID:17424768

    Krause, Bernardo; Sobrevia, Luis; Casanello, Paola

    2009-10-01

    The hypothesis of 'Developmental Origins of Health and Disease' (DOHaD) relies on the presence of mechanisms sensing and signalling a diversity of stimuli during fetal development. The mechanisms that have been broadly suggested to be involved in these processes are the epigenetic modifications that could 'record' perinatal stimuli. Since the definition of epigenetic and the associated mechanisms are conflictive, in this review epigenetic was defined as 'chromosome-based mechanisms that can change the phenotypic plasticity in a cell or organism'. The most understood epigenetic mechanisms (i.e. DNA methylation, histone post-translational modifications (PTM), ATP-dependent chromatin modifications and non-coding RNAs) and reported evidence for their role in fetal programming were briefly reviewed. The development of the vascular system is strongly influenced by epigenetic mechanisms. For that reason vascular cells are good candidates to be explored regarding epigenetic programming since its proved susceptibility to be imprinted. This has been described in pregnancy diseases such as intra-uterine growth restriction, gestational diabetes and pre-eclampsia, where changes in vascular function are preserved in vitro.

  5. Pregnancy threat to adolescent health.

    Science.gov (United States)

    1995-01-01

    The International Center for Research on Women (ICRW) is investigating factors which affect the nutritional status of adolescent girls in Benin, Cameroon, Ecuador, Guatemala, India, Jamaica, Mexico, Nepal, and the Philippines. The research is funded through the US Agency for International Development's Office of Nutrition. 22.5% of women in Nepal marry before they reach age 14 years, with most marrying before age 18. The research in the country has found pregnancy to be a burden among these young women which threatens their nutritional and health status as well as that of their offspring. Unequal distribution of food in the household and heavy workloads increase the level of risk faced by adolescent females. Postponing pregnancy in adolescents, however, delays the onset of increased nutritional needs in girls who are already likely to be undernourished. Delayed pregnancy also gives girls more time to complete their physical growth and avoids the risk of medical emergencies in childbirth, such as hemorrhage which, if survived, can lead to anemia which is aggravated by nutritional deficiencies. The ICRW has therefore proposed four strategies for postponing first births among female adolescents: encouraging later marriage, providing family planning and reproductive health services specially for adolescents, providing family life education about options for the future, and increasing educational opportunities for girls.

  8. Physiological parameters

    International Nuclear Information System (INIS)

    The physiological characteristics of man depend on the intake, metabolism and excretion of stable elements from food, water, and air. The physiological behavior of natural radionuclides and radionuclides from nuclear weapons testing and from the utilization of nuclear energy is believed to follow the pattern of stable elements. Hence information on the normal physiological processes occurring in the human body plays an important role in the assessment of the radiation dose received by man. Two important physiological parameters needed for internal dose determination are the pulmonary function and the water balance. In the Coordinated Research Programme on the characterization of Asian population, five participants submitted data on these physiological characteristics - China, India, Japan, Philippines and Viet Nam. During the CRP, data on other pertinent characteristics such as physical and dietary were simultaneously being collected. Hence, the information on the physiological characteristics alone, coming from the five participants were not complete and are probably not sufficient to establish standard values for the Reference Asian Man. Nonetheless, the data collected is a valuable contribution to this research programme

    Nutritional assessment focuses on evaluation of animal-specific, diet-specific, feeding management, and environmental factors. Assessment includes evaluation of a patient's medical history, comprehensive diet history, and physical examination including body weight, body condition, and muscle condition. Diagnostic testing may identify comorbidities associated with obesity or concurrent health conditions that need to be considered when developing a nutrition plan. When obesity is diagnosed during the nutritional assessment this finding along with health implications must be clearly communicated to the pet owner. Careful consideration of animal-specific, diet-specific, owner-specific, and environmental factors allows the clinician to develop a specific nutrition plan tailored to the needs of pet and owner.

    This article reviews updates and provides some data related to nutritional and orthomolecular supplementation in oncology patients with an emphasis on lung cancer, a commonly diagnosed tumor with significant nutritional disturbances. Cancer and its treatment play a significant role in nutritional imbalance which likely has negative impact on the patient both in terms of quality and quantity of life. Nutritional supplementation may correct these imbalances with significant clinical benefit both physiologically and psychologically. This review will help assist in providing clinically useful data to assess the cancer patient's nutritional status and to guide nutritional intervention to assist these patients' recovery.

    Optimal nutrition will be critical for crew members who embark on space exploration missions. Nutritional assessment provides an opportunity to ensure that crewmembers begin their missions in optimal nutritional status, to document changes during a mission and, if necessary, to provide intervention to maintain that status throughout the mission, and to assesses changes after landing in order to facilitate the return to their normal status as soon as possible after landing. We report here the findings from our nutritional assessment of astronauts who participated in the International Space Station (ISS) missions, along with flight and ground-based research findings. We also present ongoing and planned nutrition research activities. These studies provide evidence that bone loss, compromised vitamin status, and oxidative damage are the critical nutritional concerns for space travelers. Other nutrient issues exist, including concerns about the stability of nutrients in the food system, which are exposed to longterm storage and radiation during flight. Defining nutrient requirements, and being able to provide and maintain those nutrients on exploration missions, will be critical for maintaining crew member health.

  15. Quantification of natural phenomena

    International Nuclear Information System (INIS)

    The science is like a great spider's web in which unexpected connections appear and therefore it is frequently difficult to already know the consequences of new theories on those existent. The physics is a clear example of this. The Newton mechanics laws describe the physical phenomena observable accurately by means of our organs of the senses or by means of observation teams not very sophisticated. After their formulation at the beginning of the XVIII Century, these laws were recognized in the scientific world as a mathematical model of the nature. Together with the electrodynamics law, developed in the XIX century, and the thermodynamic one constitutes what we call the classic physics. The state of maturity of the classic physics at the end of last century it was such that some scientists believed that the physics was arriving to its end obtaining a complete description of the physical phenomena. The spider's web of the knowledge was supposed finished, or at least very near its termination. It ended up saying, in arrogant form, that if the initial conditions of the universe were known, we could determine the state of the same one in any future moment. Two phenomena related with the light would prove in firm form that mistaken that they were, creating unexpected connections in the great spider's web of the knowledge and knocking down part of her. The thermal radiation of the bodies and the fact that the light spreads to constant speed in the hole, without having an absolute system of reference with regard to which this speed is measured, they constituted the decisive factors in the construction of a new physics. The development of sophisticated of measure teams gave access to more precise information and it opened the microscopic world to the observation and confirmation of existent theories

  16. Phylogeny of Aging and Related Phenoptotic Phenomena.

    Libertini, G

    2015-12-01

    The interpretation of aging as adaptive, i.e. as a phenomenon genetically determined and modulated, and with an evolutionary advantage, implies that aging, as any physiologic mechanism, must have phylogenetic connections with similar phenomena. This review tries to find the phylogenetic connections between vertebrate aging and some related phenomena in other species, especially within those phenomena defined as phenoptotic, i.e. involving the death of one or more individuals for the benefit of other individuals. In particular, the aim of the work is to highlight and analyze similarities and connections, in the mechanisms and in the evolutionary causes, between: (i) proapoptosis in prokaryotes and apoptosis in unicellular eukaryotes; (ii) apoptosis in unicellular and multicellular eukaryotes; (iii) aging in yeast and in vertebrates; and (iv) the critical importance of the DNA subtelomeric segment in unicellular and multicellular eukaryotes. In short, there is strong evidence that vertebrate aging has clear similarities and connections with phenomena present in organisms with simpler organization. These phylogenetic connections are a necessary element for the sustainability of the thesis of aging explained as an adaptive phenomenon, and, on the contrary, are incompatible with the opposite view of aging as being due to the accumulation of random damages of various kinds.

Taking into account the functional dependence $\\varepsilon=\\varepsilon(E,B)$ and $\\mu=\\mu(E,B)$ for the dielectric coefficients, a set of phenomena related to the birefringence of the electromagnetic waves induced by external fields are derived and discussed. Our results contemplate the known cases already reported in the literature: Kerr, Cotton-Mouton, Jones and magnetoelectric effects. Moreover, new effects are presented here as well as the perspectives of its experimental confirmations.

    nutritional management of children and adolescents with cystic fibrosis. DATA SOURCES: MEDLINE (PubMed version and Latin American and Caribbean Center on Health Sciences Information (LILACS, from 1984 to 2009. The combination of the following keywords were applied: cystic fibrosis, nutritional status, child, and adolescent. DATA SYNTHESIS: Cystic fibrosis (CF is a genetic disease, chronic, progressive, and fatal. It is caused by a defect in the transmembrane regulatory protein that regulates the flow of chlorine, sodium and water across the apical membrane of epithelial cells. CF patients are vulnerable to malnutrition resulting from the imbalance between food intake, energy expenditure and loss. New insights into the pathophysiology of the disease have resulted in significant changes in current recommendations for energy and especially lipids intake. There are many interrelated factors that affect the nutritional status of CF patients, such as genetic mutation, pancreatic insufficiency, bowel resection, loss of bile salts and acids, gastroesophageal reflux disease, lung inflammation and infections, diabetes, and emotional conditions. The importance of nutrition in the survival of CF patients is well established, as well as the association between malnutrition and deterioration of lung function. CONCLUSIONS: Nutritional monitoring and dietary counseling are key elements in the management of patients with CF aiming to control the symptoms and the progression of the disease in order to provide better quality of life.

    This project developed and supported a technology base in nonequilibrium phenomena underpinning fundamental issues in condensed matter and materials science, and applied this technology to selected problems. In this way the increasingly sophisticated synthesis and characterization available for classes of complex electronic and structural materials provided a testbed for nonlinear science, while nonlinear and nonequilibrium techniques helped advance our understanding of the scientific principles underlying the control of material microstructure, their evolution, fundamental to macroscopic functionalities. The project focused on overlapping areas of emerging thrusts and programs in the Los Alamos materials community for which nonlinear and nonequilibrium approaches will have decisive roles and where productive teamwork among elements of modeling, simulations, synthesis, characterization and applications could be anticipated--particularly multiscale and nonequilibrium phenomena, and complex matter in and between fields of soft, hard and biomimetic materials. Principal topics were: (i) Complex organic and inorganic electronic materials, including hard, soft and biomimetic materials, self-assembly processes and photophysics; (ii) Microstructure and evolution in multiscale and hierarchical materials, including dynamic fracture and friction, dislocation and large-scale deformation, metastability, and inhomogeneity; and (iii) Equilibrium and nonequilibrium phases and phase transformations, emphasizing competing interactions, frustration, landscapes, glassy and stochastic dynamics, and energy focusing.

    We discuss phenomena associated with "EIT Wave" transients. These phenomena include coronal mass ejections, flares, EUV/SXR dimmings, chromospheric waves, Moreton waves, solar energetic particle events, energetic electron events, and radio signatures. Although the occurrence of many phenomena correlate with the appearance of EIT waves, it is difficult to mfer which associations are causal. The presentation will include a discussion of correlation surveys of these phenomena.

    There has been a long history of interaction between mathematics and physiology. This book looks in detail at a wide selection of mathematical models in physiology, showing how physiological problems can be formulated and studied mathematically, and how such models give rise to interesting and challenging mathematical questions. With its coverage of many recent models it gives an overview of the field, while many older models are also discussed, to put the modern work in context. In this second edition the coverage of basic principles has been expanded to include such topics as stochastic differential equations, Markov models and Gibbs free energy, and the selection of models has also been expanded to include some of the basic models of fluid transport, respiration/perfusion, blood diseases, molecular motors, smooth muscle, neuroendrocine cells, the baroreceptor loop, turboglomerular oscillations, blood clotting and the retina. Owing to this extensive coverage, the second edition is published in two volumes. ...

  10. Physiological breeding.

    Reynolds, Matthew; Langridge, Peter

    2016-06-01

    Physiological breeding crosses parents with different complex but complementary traits to achieve cumulative gene action for yield, while selecting progeny using remote sensing, possibly in combination with genomic selection. Physiological approaches have already demonstrated significant genetic gains in Australia and several developing countries of the International Wheat Improvement Network. The techniques involved (see Graphical Abstract) also provide platforms for research and refinement of breeding methodologies. Recent examples of these include screening genetic resources for novel expression of Calvin cycle enzymes, identification of common genetic bases for heat and drought adaptation, and genetic dissection of trade-offs among yield components. Such information, combined with results from physiological crosses designed to test novel trait combinations, lead to more precise breeding strategies, and feed models of genotype-by-environment interaction to help build new plant types and experimental environments for future climates.

    Full Text Available Introduction: The prevalence of childhood and adolescent obesity is increasing, with negative medical and psychosocial consequences. Aims: This study examines the association between weight status and nutrient intake, sport and leisure habits of middle school students in Bologna (Italy. Methods: Anthropometric data (height, weight of 598 subjects (321 males and 277 females 11-14 years old were collected. Questionnaires on nutrient intake, sport and leisure behaviour were administered. Results: Protein, carbohydrate and total fat intakes of the adolescents were higher than the recommended ranges in all age groups and in both sexes. The proportion of energy from protein and total fat was higher than recommended, but the percentage from carbohydrate was lower. A significant proportion of the adolescents had a cholesterol intake above the Italian RDA and lower than recommended intakes for micronutrients. The prevalence of overweight and obesity is higher in males than in females at all ages (overweight: 35.2 vs 31.6 at 11 yrs.; 27.5 vs 20.2 at 12 yrs.; 18.6 vs 17.8 at 13 yrs.; 18.7 vs 10.9 at 14 yrs.; obesity: 5.5 vs 3.2 at 12 yrs.; 3.9 vs 1.1 at 13 yrs.; 5.3 vs 3.6 at 14 yrs., except in subjects 11 years old (obesity: 7.4 vs 10.5. The overweight and obese adolescents consumed less carbohydrates and less fibre than their normal weight and underweight counterparts. Conclusion: The results of the present study indicate an unbalanced diet of the Bologna adolescents, which could damage their health and quality of life.Introducción: La prevalencia de la obesidad de la infancia y la adolescencia sigue aumentando con sus consecuencias negativas médicas y psicológicas.

  14. Crystallization phenomena in slags

    Orrling, Carl Folke

    2000-09-01

    The crystallization of the mold slag affects both the heat transfer and the lubrication between the mold and the strand in continuous casting of steel. In order for mold slag design to become an engineering science rather than an empirical exercise, a fundamental understanding of the melting and solidification behavior of a slag must be developed. Thus it is necessary to be able to quantify the phenomena that occur under the thermal conditions that are found in the mold of a continuous caster. The double hot thermocouple technique (DHTT) and the Confocal Laser Scanning Microscope used in this study are two novel techniques for investigating melting and solidification phenomena of transparent slags. Results from these techniques are useful in defining the phenomena that occur when the slag film infiltrates between the mold and the shell of the casting. TTT diagrams were obtained for various slags and indicated that the onset of crystallization is a function of cooling rate and slag chemistry. Crystal morphology was found to be dependent upon the experimental temperature and four different morphologies were classified based upon the degree of melt undercooling. Continuous cooling experiments were carried out to develop CCT diagrams and it was found that the amount and appearance of the crystalline fraction greatly depends on the cooling conditions. The DHTT can also be used to mimic the cooling profile encountered by the slag in the mold of a continuous caster. In this differential cooling mode (DCT), it was found that the details of the cooling rate determine the actual response of the slag to a thermal gradient and small changes can lead to significantly different results. Crystal growth rates were measured and found to be in the range between 0.11 mum/s to 11.73 mum/s depending on temperature and slag chemistry. Alumina particles were found to be effective innoculants in oxide melts reducing the incubation time for the onset of crystallization and also extending

    Kreuzer, Hans

    1987-01-01

    This book contains the proceedings of the first Workshop on Interface Phenomena, organized jointly by the surface science groups at Dalhousie University and the University of Maine. It was our intention to concentrate on just three topics related to the kinetics of interface reactions which, in our opinion, were frequently obscured unnecessarily in the literature and whose fundamental nature warranted an extensive discussion to help clarify the issues, very much in the spirit of the Discussions of the Faraday Society. Each session (day) saw two principal speakers expounding the different views; the session chairmen were asked to summarize the ensuing discussions. To understand the complexity of interface reactions, paradigms must be formulated to provide a framework for the interpretation of experimen­ tal data and for the construction of theoretical models. Phenomenological approaches have been based on a small number of rate equations for the concentrations or mole numbers of the various species involved i...

  18. Fast fission phenomena

    International Nuclear Information System (INIS)

    Experimental studies of fast fission phenomena are presented. The paper is divided into three parts. In the first part, problems associated with fast fission processes are examined in terms of interaction potentials and a dynamic model is presented in which highly elastic collisions, the formation of compound nuclei and fast fission appear naturally. In the second part, a description is given of the experimental methods employed, the observations made and the preliminary interpretation of measurements suggesting the occurence of fast fission processes. In the third part, our dynamic model is incorporated in a general theory of the dissipative processes studied. This theory enables fluctuations associated with collective variables to be calculated. It is applied to highly inelastic collisions, to fast fission and to the fission dynamics of compound nuclei (for which a schematic representation is given). It is with these calculations that the main results of the second part can be interpreted

  19. Vacuum arc anode phenomena

    International Nuclear Information System (INIS)

    A brief review of anode phenomena in vacuum arcs is presented. Discussed in succession are: the transition of the arc into the anode spot mode; the temperature of the anode before, during and after the anode spot forms; and anode ions. Characteristically the anode spot has a temperature of the order of the atmospheric boiling point of the anode material and is a copious source of vapor and energetic ions. The dominant mechanism controlling the transition of the vacuum arc into the anode spot mode appears to depend upon the electrode geometry, the electrode material, and the current waveform of the particular vacuum arc being considered. Either magnetic constriction in the gap plasma or gross anode melting can trigger the transition; indeed, a combination of the two is a common cause of anode spot formation

    Full Text Available A deficiência de ferro é o distúrbio nutricional mais comum no mundo e constitui a maior causa de anemia associada às condições onde há erro alimentar, perda crônica de sangue ou quando ocorre o crescimento rápido, como na infância, na gravidez e na adolescência. Esta deficiência acarreta prejuízos no desenvolvimento neuropsicomotor, na capacidade de aprendizagem, no apetite, no crescimento e na resposta do sistema imunológico. Na adolescência, além de com frequência observarmos hábitos alimentares inadequados, estão presentes intensas mudanças fisiológicas e psicossociais que, em associação, podem comprometer o crescimento e aumentar o risco do desenvolvimento de deficiência de ferro e outras carências nutricionais, sobretudo na fase púbere. Desta forma, o diagnóstico de deficiência de ferro entre os adolescentes deve ser lembrado a fim de que medidas possam ser tomadas para diminuir a incidência de anemia, do comprometimento do rendimento escolar e do sistema imunológico, neste período da vida.Iron deficiency is the most common nutritional disorder in the world and is a major cause of anemia associated with situations involving chronic blood loss or rapid growth such as during infancy, pregnancy and adolescence. This deficiency leads to impairment in psychomotor development, learning ability, appetite, growth and immune response. In adolescence, inadequate dietary habits are often observed and intensive physiological and psychological changes are seen that when combined can impair growth and increase the risk of developing iron deficiency or other nutritional disorders, especially during puberty. Thus, the diagnosis of iron deficiency among adolescents should always be considered so that measures can be taken to reduce the incidence of anemia, impairment of the immune system and improve school performance.

  15. Nuclear fuel deformation phenomena

    International Nuclear Information System (INIS)

    Nuclear fuel encounters severe thermomechanical environments. Its mechanical response is profoundly influenced by an underlying heterogeneous microstructure but also inherently dependent on the temperature and stress level histories. The ability to adequately simulate the response of such microstructures, to elucidate the associated macroscopic response in such extreme environments is crucial for predicting both performance and transient fuel mechanical responses. This chapter discusses key physical phenomena and the status of current modelling techniques to evaluate and predict fuel deformations: creep, swelling, cracking and pellet-clad interaction. This chapter only deals with nuclear fuel; deformations of cladding materials are discussed elsewhere. An obvious need for a multi-physics and multi-scale approach to develop a fundamental understanding of properties of complex nuclear fuel materials is presented. The development of such advanced multi-scale mechanistic frameworks should include either an explicit (domain decomposition, homogenisation, etc.) or implicit (scaling laws, hand-shaking,...) linkage between the different time and length scales involved, in order to accurately predict the fuel thermomechanical response for a wide range of operating conditions and fuel types (including Gen-IV and TRU).

  16. Acid Deposition Phenomena

    International Nuclear Information System (INIS)

    Acid deposition, commonly known as acid rain, occurs when emissions from the combustion of fossil fuels and other industrial processes undergo complex chemical reactions in the atmosphere and fall to the earth as wet deposition (rain, snow, cloud, fog) or dry deposition (dry particles, gas). Rain and snow are already naturally acidic, but are only considered problematic when less than a ph of 5.0 The main chemical precursors leading to acidic conditions are atmospheric concentrations of sulfur dioxide (SO2) and nitrogen oxides (NOx). When these two compounds react with water, oxygen, and sunlight in the atmosphere, the result is sulfuric (H2SO4) and nitric acids (HNO3), the primary agents of acid deposition which mainly produced from the combustion of fossil fuel and from petroleum refinery. Airborne chemicals can travel long distances from their sources and can therefore affect ecosystems over broad regional scales and in locations far from the sources of emissions. According to the concern of petroleum ministry with the environment and occupational health, in this paper we will discussed the acid deposition phenomena through the following: Types of acidic deposition and its components in the atmosphere Natural and man-made sources of compounds causing the acidic deposition. Chemical reactions causing the acidic deposition phenomenon in the atmosphere. Factors affecting level of acidic deposition in the atmosphere. Impact of acid deposition. Procedures for acidic deposition control in petroleum industry

    The focus of the Regulatory Physiology discipline of the Space Physiology and Countermeasures Program is twofold. First, to determine and study how microgravity and associated factors of space flight affect the regulatory mechanisms by which humans adapt and achieve homeostasis and thereby regulate their ability to respond to internal and external signals; and, second, to study selected physiological systems that have been demonstrated to be influenced by gravity. The Regulatory Physiology discipline, as defined here, is composed of seven subdisciplines: (1) Circadian Rhythms, (2) Endocrinology, (3) Fluid and Electrolyte Regulation, (4) Hematology, (5) Immunology, (6) Metabolism and Nutrition, and (7) Temperature Regulation. The purpose of this Discipline Science Plan is to provide a conceptual strategy for NASA's Life Sciences Division research and development activities in the area of regulatory physiology. It covers the research areas critical to NASA's programmatic requirements for the Extended-Duration Orbiter, Space Station Freedom, and exploration mission science activities. These science activities include ground-based and flight; basic, applied, and operational; and animal and human research and development. This document summarizes the current status of the program, outlines available knowledge, establishes goals and objectives, identifies science priorities, and defines critical questions in regulatory physiology. It contains a general plan that will be used by both NASA Headquarters Program Offices and the field centers to review and plan basic, applied, and operational intramural and extramural research and development activities in this area.

    Mammals, including humans, can synthesize the vitamin nicotinamide from tryptophan in the liver. The resultant nicotinamide is distributed to non-hepatic tissues. We have studied the effects of changes in tryptophan–nicotinamide metabolism on niacin nutritional status. The liver plays a critical role in nicotinamide supply. Animal studies showed that the tryptophan–nicotinamide pathway is affected by physiological conditions, the presence of disease, nutrients, hormones, and chemicals. Human ...

  3. Food products made with glycomacropeptide, a low-phenylalanine whey protein, provide a new alternative to amino Acid-based medical foods for nutrition management of phenylketonuria.

    2012-08-01

    Phenylketonuria (PKU), an inborn error in phenylalanine metabolism, requires lifelong nutrition management with a low-phenylalanine diet, which includes a phenylalanine-free amino acid-based medical formula to provide the majority of an individual's protein needs. Compliance with this diet is often difficult for older children, adolescents, and adults with PKU. The whey protein glycomacropeptide (GMP) is ideally suited for the PKU diet because it is naturally low in phenylalanine. Nutritionally complete, acceptable medical foods and beverages can be made with GMP to increase the variety of protein sources for the PKU diet. As an intact protein, GMP improves protein use and increases satiety compared with amino acids. Thus, GMP provides a new, more physiologic source of low-phenylalanine dietary protein for people with PKU. PMID:22818728

    Full Text Available Este trabajo se justifica doblemente: como parte de una investigación superior sobre análisis de tipos de personajes hasta el momento marginales en series de ficción televisivas y como contribución a la reflexión de la invasión del adolescente en la pantalla televisiva como reclamo en busca de un sector de audiencias. Su objetivo es mostrar los prototipos de adolescentes que se generan en los productos audiovisuales televisivos que se emiten en la actualidad en España. Para ello se ha diseñado una metodología basada en un doble movimiento: fase de análisis cuantitativo de series y personajes; y fase de análisis cualitativo y deconstructivo de los personajes adolescentes en su proceso identitario. El resultado confirma la existencia de una potente estandarización de actitudes y apariencias con respecto a los modelos propuestos por series americanas por encima de las españolas. La conclusión habla de la generación de prototipos adolescentes contradictorios. This work is doubly justified: as a part of a bigger research project on types of so far marginalized characters in television drama serials; and as a contribution to the teenage invasion of the TV screen as a call to this kind of audience. The aim of this paper is to show prototypes of adolescents created in televised products broadcast today in Spain. The methodology is based on two factors: a quantitative one about serials and characters, and a qualitative analysis of drama serials and teen characters. The result confirms the existence of a powerful standardized appearance and attitude regarding the models proposed by American series over the Spanish ones. The conclusion discusses the generation of contradictory teenage prototypes.

    Full Text Available Questions concerning the fundamental effects of nutrition on gene function are now being elucidated as the human genome project has been completed. Nutritional genomics seeks to expand the use of foods to achieve human genetic potential, while reducing the risk of diseases. As issues such as nutrigenomics (dietary influence on gene function and nutrigenetics (genomic reaction to diet are unraveled, thepotential for personalized nutrition becomes attainable. It has been stated that “genomics is to the 21st century what infectious disease was to the 20th century”. The nucleotide sequence of DNA was once seen as the only mechanism by which genetic information could be transmitted between generations. Phenotypic variation resulted from recombination and, occasionally, genetic mutation. This widely accepted concept is now undergoing modification as evidence builds to support the idea that reversible, heritable changes in gene function - termed “epigenetics”- can occur without a change in the sequence of nuclear DNA (i.e., non-Mendelian inheritance. The word epigenetics is of Greek origin and literallymeans over and above (epi the genome. The terminology“same genome, different epigenome” has been demonstrated in several experiments. As research and understanding advances, dietary advice based on the human genome will become more prevalent and new pharmacological interventions may be developed.

    During adolescence, young people are in a sensitive transition period when they gradually take over the responsibility for their own eating habits, health attitudes and behaviours and create lifelong habits so it is essential that they adopt healthy habits according to dietary recommendations. Knowledge is one of the factors necessary for the changes in dietary habits. The'objective of this study was to gain insight in nutritional knowledge and dietary habits of adolescents. The sample included 117 adolescents aged 17-19 years. Self-administered, anonymous questionnaire, representing modified version of General Nutrition Knowledge Questionnaire was used to assess general characteristics, nutritional knowledge about nutrients, dietary recommendations, sources of nutrients, diet-disease relationship, and dietary habits. Less than one third of adolescents showed satisfactory knowledge, but boys, adolescents from rural environment and overweight adolescents showed significantly lower knowledge unlike others. Meal skipping was present habit, especially for breakfast consumption. Especially high consumption of meat and meat products was noted for boys, while fruit and vegetables for girls. Fad dieting was quite practiced habit, especially in girls and overweight adolescents. Among girls, high consumption of sweets was confirmed, while boys showed high consumption of soft drinks. Television presents the main source of infor- mation about nutrition for adolescents. Collected data shows similarity with other research in Europe and North America that confirm strong influence of globalization and fast spread of unhealthy habits. The results pointed out weak spots in nutritional knowledge and revealed unhealthy eating habits. This information is necessary for the development of new approaches to modulate their knowledge and consequently act on their behaviour. Behavioral changes would include higher number of meals per day, regular breakfast consumption, higher intake of fish

    Full Text Available Abstract Background Adolescents rarely seek psychiatric help; they even hesitate to disclose their feelings to their parents. However; the adolescents especially the females experience depressive symptoms more frequently than general population. Do they experience classic depressive symptoms? Are there symptoms specific to this subpopulation? Aim of the study Through this study, the authors aimed to estimate the prevalence of depressive disorders in Egyptian adolescent female students. They also expected a characteristic profile of symptoms for the adolescent females. However available literature provides no guidance in the description of this profile of symptoms. Methods A number of 602 adolescent females were interviewed, and subjected to General Health Questionnaire (GHQ; Children Depression Inventory (CDI, Structured Clinical Interview for DSM-IV Axis-I Disorders (SCID-I, then Hamilton Rating Scale for Depression (Ham-D. Results were analyzed by the use of SPSS-15. Results The study revealed the prevalence of depression in the sample of the study to be 15.3% (measured by CDI, and 13.3% (measured by SCID-I. Fatigue was the most common presenting depressive symptom (81.3%, in addition to other emotional, cognitive and physiological symptoms. Suicidal ideations were the most common suicidal symptoms in depressed adolescent females (20%, with 2.5% serious suicidal attempts. Conclusions The somatic symptoms were by far the most common presenting symptom for female adolescents suffering from depressive disorders. Depressive phenomena including unexplained fatigue, decreased energy, psychomotor changes, lack of concentration, weight changes and suicidal ideations may be the presenting complaints instead of the classic sad mood.

  3. Wave phenomena in sunspots

    Löhner-Böttcher, Johannes

    2016-03-01

    Context: The dynamic atmosphere of the Sun exhibits a wealth of magnetohydrodynamic (MHD) waves. In the presence of strong magnetic fields, most spectacular and powerful waves evolve in the sunspot atmosphere. Allover the sunspot area, continuously propagating waves generate strong oscillations in spectral intensity and velocity. The most prominent and fascinating phenomena are the 'umbral flashes' and 'running penumbral waves' as seen in the sunspot chromosphere. Their nature and relation have been under intense discussion in the last decades. Aims: Waves are suggested to propagate upward along the magnetic field lines of sunspots. An observational study is performed to prove or disprove the field-guided nature and coupling of the prevalent umbral and penumbral waves. Comprehensive spectroscopic observations at high resolution shall provide new insights into the wave characteristics and distribution across the sunspot atmosphere. Methods: Two prime sunspot observations were carried out with the Dunn Solar Telescope at the National Solar Observatory in New Mexico and with the Vacuum Tower Telescope at the Teide Observatory on Tenerife. The two-dimensional spectroscopic observations were performed with the interferometric spectrometers IBIS and TESOS. Multiple spectral lines are scanned co-temporally to sample the dynamics at the photospheric and chromospheric layers. The time series (1 – 2.5 h) taken at high spatial and temporal resolution are analyzed according to their evolution in spectral intensities and Doppler velocities. A wavelet analysis was used to obtain the wave power and dominating wave periods. A reconstruction of the magnetic field inclination based on sunspot oscillations was developed. Results and conclusions: Sunspot oscillations occur continuously in spectral intensity and velocity. The obtained wave characteristics of umbral flashes and running penumbral waves strongly support the scenario of slow-mode magnetoacoustic wave propagation along

    Young, Eric D.

    The analysis of physiological sound in the peripheral auditory system solves three important problems. First, sound energy impinging on the head must be captured and presented to the transduction apparatus in the ear as a suitable mechanical signal; second, this mechanical signal needs to be transduced into a neural representation that can be used by the brain; third, the resulting neural representation needs to be analyzed by central neurons to extract information useful to the animal. This chapter provides an overview of some aspects of the first two of these processes. The description is entirely focused on the mammalian auditory system, primarily on human hearing and on the hearing of a few commonly used laboratory animals (mainly rodents and carnivores). Useful summaries of non-mammalian hearing are available [1]. Because of the large size of the literature, review papers are referenced wherever possible.

    Few supplement combinations that are marketed to athletes are supported by scientific evidence of their effectiveness. Quite often, under the rigor of scientific investigation, the patented combination fails to provide any greater benefit than a group given the active (generic) ingredient. The focus of this chapter is supplement combinations and dosing strategies that are effective at promoting an acute physiological response that may improve/enhance exercise performance or influence chronic adaptations desired from training. In recent years, there has been a particular focus on two nutritional ergogenic aids—creatine monohydrate and protein/amino acids—in combination with specific nutrients in an effort to augment or add to their already established independent ergogenic effects. These combinations and others are discussed in this chapter.

    This topical volume on Advanced Diffusion Processes and Phenomena addresses diffusion in a wider sense of not only mass diffusion but also heat diffusion in fluids and solids. Both diffusion phenomena play an important role in the characterization of engineering materials and corresponding structures. Understanding these different transport phenomena at many levels, from atomistic to macro, has therefore long attracted the attention of many researchers in materials science and engineering and related disciplines. The present topical volume captures a representative cross-section of some of the

    Acute illness induces major physiological responses, which favor the adaptation of the organism to stress and injury. The metabolic response plays key roles in maintenance of vital functions and promotion of the healing mechanisms. All the components of energy expenditure are modified, particularly the resting metabolism. The regulation of carbohydrate metabolism is also markedly altered. Such patients are characterized by fasting and postprandial hyperglycemia, insulin resistance, and by a stimulation of the hepatic glucose production in fasted and fed states. Lipolysis and increased fat oxidation are typically observed. Ketogenesis processes are inhibited, concurring to alter the adaptation to starvation. Protein turnover is stimulated with a preponderance of the catabolic processes, even during full nutritional support. This induces a state of resistance to feeding, leading to a progressive depletion of the fat free mass. Such progressive tissue catabolism cannot be reversed by hypercaloric nutrition or growth factors. Specific nutrients (aminoacids, micronutrients, PUFA) may offer interesting perspectives in stimulating immunity, improving the antioxidant balance or modulating the inflammatory response.

    Full Text Available Social reality originates from social interaction in a social group. It is consolidated with social consensus. It is transcendent and relatively stable. Social reality is maintained in relatively isolated, balanced social environment. Majority of members in a social group spontaneously reacts to deviations. These are characteristics which many authors contribute to social reality. If social reality is to be understood as a collection of social-psychological phenomena, of which the important factor is structuring of environment, then these phenomena have to have similar characteristics as social reality itself. In this article various definitions of selected phenomena are presented, such as social norms, group values, stereotypes, prejudice, social representations, etc. The article contends that despite of lack of clear definitions, we can find views that connect the aforementioned characteristics to social-psychological phenomena.

    Many natural phenomena can be described by power-laws. A closer look at various experimental data reveals more or less significant deviations from a 1/f spectrum. We exemplify such cases with phenomena offered by molecular biology, cell biophysics, and cognitive psychology. Some of these cases can be described by first order autoregressive (AR) models or by higher order AR models which are short range correlation models. The calculations are checked against astrophysical data which were fitted to a an AR model by a different method. We found that our fitting method of the data give similar results for the astrhophysical data and therefore applied the method for examples mentioned above. Our results show that such phenomena can be described by first or higher order of AR models. Therefore such examples are described by short range correlation properties while they can be easily confounded with long range correlation phenomena.

  7. Geriatric nutrition.

    Markham, R W; Hodgkins, E M

    1989-01-01

    In recent decades, veterinary medicine has become more successful in prolonging the healthy, useful lives of pets. As a result, the practitioner spends a greater part of each practice day caring for the geriatric animal, both healthy and unhealthy. Because of their longevity, older pets are typically regular family members, with owners who seek the finest health care possible for their pets. The practice of geriatric medicine most properly should begin not when the dog or cat reaches some specific "golden" age, but rather when the wiggly, robust puppy or kitten receives its first examination. Like all parts of a sound preventive program, geriatric nutrition best follows from a well-considered juvenile and adult nutrition program. Furthermore, once it becomes senior, the "well" geriatric is as much a candidate for a diet designed especially to accommodate old age changes as is his unhealthy contemporary. In fact, evidence suggests that appropriate dietary management of the healthy, but often subclinical, patient may help postpone the signs of dysfunction and increase quality and length of life. A knowledge of the most significant nutrients and the impact of each on aging systems is now, and will become increasingly more, important to the progressive, skillful veterinarian. PMID:2646815

  13. Nutritional support for acute pancreatitis.

    Pisters, P W; Ranson, J H

    1992-09-01

    The current review has summarized current data relevant to the nutritional support of patients with acute pancreatitis. Selection of the most appropriate form of nutritional support for patients with acute pancreatitis is intimately linked to a thorough understanding of the effects of various forms of enteral and parenteral nutrition on physiologic exocrine secretory mechanisms. Two basic concepts have emerged from the multiple studies that have addressed these issues to date: 1, enteral feeds should have low fat composition and be delivered distal to the ligament of Treitz to minimize exocrine pancreatic secretion and 2, parenteral substrate infusions, alone or in combinations similar to those administered during TPN, do not stimulate exocrine pancreatic secretion. From a practical standpoint, most patients with acute pancreatitis are diagnosed by nonoperative means and will manifest some degree of paralytic ileus during the early phase of the disease. Therefore, jejunal feeds are usually not a therapeutic option early in the course of this disease. On the basis of the clinical studies reviewed herein we propose general guidelines for the nutritional support of patients with acute pancreatitis: 1, most patients with mild uncomplicated pancreatitis (one to two prognostic signs) do not benefit from nutritional support; 2, nutritional support should begin early in the course of patients with moderate to severe disease (as soon as hemodynamic and cardiorespiratory stability permit); 3, initial nutritional support should be through the parenteral route and include fat emulsion in amounts sufficient to prevent essential fatty acid deficiency (no objective data exist to recommend specific amino acid formulations); 4, patients requiring operation for diagnosis or complications of the disease should have a feeding jejunostomy placed at the time of operation for subsequent enteral nutrition using a low fat formula, such as Precision HN (Sandoz, 1.3 percent calories as fat

    In biological phenomena there are indications that within the long pulse-length of the action potential on millisecond scale, there is additional ultrashort perturbation encoding that provides the brain with detailed information about the origin (location) and physiological characteristics. The objective is to identify the mechanism-of-action providing the potential for encoding in biological signal propagation. The actual molecular processes involved in the initiation of the action potential have been identified to be in the femtosecond and pico-second scale. The depolarization process of the cellular membrane itself, leading to the onset of the actionpotential that is transmitted to the brain, however is in the millisecond timeframe. One example of the femtosecond chemical interaction is the photoresponse of bacteriorhodopsin. No clear indication for the spatial encoding has so far been verified. Further research will be required on a cellular signal analysis level to confirm or deny the spatial and physiological encoding in the signal wave-trains of intercellular communications and sensory stimuli. The pathological encoding process for cardiac depolarization is however very pronounced and validated, however this electro-chemical process is in the millisecond amplitude and frequency modulation spectrum

  5. Containment severe accident thermohydraulic phenomena

    International Nuclear Information System (INIS)

    This report describes and discusses the containment accident progression and the important severe accident containment thermohydraulic phenomena. The overall objective of the report is to provide a rather detailed presentation of the present status of phenomenological knowledge, including an account of relevant experimental investigations and to discuss, to some extent, the modelling approach used in the MAAP 3.0 computer code. The MAAP code has been used in Sweden as the main tool in the analysis of severe accidents. The dependence of the containment accident progression and containment phenomena on the initial conditions, which in turn are heavily dependent on the in-vessel accident progression and phenomena as well as associated uncertainties, is emphasized. The report is in three parts dealing with: * Swedish reactor containments, the severe accident mitigation programme in Sweden and containment accident progression in Swedish PWRs and BWRs as predicted by the MAAP 3.0 code. * Key non-energetic ex-vessel phenomena (melt fragmentation in water, melt quenching and coolability, core-concrete interaction and high temperature in containment). * Early containment threats due to energetic events (hydrogen combustion, high pressure melt ejection and direct containment heating, and ex-vessel steam explosions). The report concludes that our understanding of the containment severe accident progression and phenomena has improved very significantly over the parts ten years and, thereby, our ability to assess containment threats, to quantify uncertainties, and to interpret the results of experiments and computer code calculations have also increased.

    1999-01-01

    Full Text Available As first discovered by Choptuik, the black hole threshold in the space of initial data for general relativity shows both surprising structure and surprising simplicity. Universality, power-law scaling of the black hole mass, and scale echoing have given rise to the term 'critical phenomena'. They are explained by the existence of exact solutions which are attractors within the black hole threshold, that is, attractors of codimension one in phase space, and which are typically self-similar. This review gives an introduction to the phenomena, tries to summarize the essential features of what is happening, and then presents extensions and applications of this basic scenario. Critical phenomena are of interest particularly for creating surprising structure from simple equations, and for the light they throw on cosmic censorship and the generic dynamics of general relativity.

    2009-01-01

    Nanoscale physics has become one of the rapidly developing areas of contemporary physics because of its direct relevance to newly emerging area, nanotechnologies. Nanoscale devices and quantum functional materials are usually constructed based on the results of fundamental studies on nanoscale physics. Therefore studying physical phenomena in nanosized systems is of importance for progressive development of nanotechnologies. In this context study of complex phenomena in such systems and using them for controlling purposes is of great practical importance. Namely, such studies are brought together in this book, which contains 27 papers on various aspects of nanoscale physics and nonlinear dynamics.

  14. Exercise Effects on Sleep Physiology

    Full Text Available This mini-review focuses on the effects of exercise on sleep. In its early days, sleep research largely focused on central nervous system (CNS physiology using standardized tabulations of several sleep-specific landmark electroencephalogram (EEG waveforms. Though coarse, this method has enabled the observation and inspection of numerous uninterrupted sleep phenomena. Thus, research on the effects of exercise on sleep began, in the 1960’s, with a focus primarily on sleep EEG (CNS sleep changes. Those early studies found only small effects of exercise on sleep. More recent sleep research has explored not only CNS functioning, but somatic physiology as well. As physical exercise mostly affects somatic functions, endocrine and autonomic nervous system (ANS changes that occur during sleep should be affected by daytime exercise. Since endocrinological, metabolic and autonomic changes can be measured during sleep, it should be possible to assess exercise effects on somatic physiology in addition to CNS sleep quality, building from standard polysomnographic (PSG techniques. Incorporating measures of somatic physiology in the quantitative assessment of sleep could further our understanding of sleep's function as an auto-regulatory, global phenomenon.

In its early days, sleep research largely focused on central nervous system (CNS) physiology using standardized tabulations of several sleep-specific landmark electroencephalogram (EEG) waveforms. Though coarse, this method has enabled the observation and inspection of numerous uninterrupted sleep phenomena. The research on the effects of exercise on sleep began, in the 1960s, with a focus primarily on sleep related EEG changes (CNS sleep). Those early studies found only small effects of exercise on sleep. However, more recent sleep research has explored not only CNS functioning, but somatic physiology as well. Sleep should be affected by daytime exercise, as physical activity alters endocrine, autonomic nervous system (ANS), and somatic functions. Since endocrinological, metabolic, and autonomic changes can be measured during sleep, it should be possible to assess exercise effects on somatic physiology in addition to CNS sleep quality, evaluated by standard polysomnographic (PSG) techniques. Additional measures of somatic physiology have provided enough evidences to conclude that the auto-regulatory, global regulation of sleep is not the exclusive domain of the CNS, but it is heavily influenced by inputs from the rest of the body.

    With improvements in health care, living standards, and socioeconomic status, more adults are living to old age. As the population ages, it is increasingly important to understand the factors that affect the nutritional status and thus the health status of older adults. Many factors contribute to inadequate nutrition, including health status, financial capacities, mobility, exercise, and physiologic needs. This article considered only the potential changes in nutritional needs because of alterations in the gastrointestinal tract owing to aging. One of the most remarkable changes with aging is the frequent development of atrophic gastritis and the inability to secrete gastric acid. This process affects approximately a third of older adults in the United States and only recently was recognized to be due to infection by H. pylori in the majority of cases. The lack of gastric acid in atrophic gastritis may lead to small intestinal bacterial overgrowth and influences the absorption of a variety of micronutrients, including iron, folate, calcium, vitamin K, and vitamin B12. Lactose maldigestion is a frequent condition in older adults and is extremely common worldwide. The intolerance of dairy products leads to avoidance of these foods and likely contributes to the development of osteopenia. Overall, the small intestine and pancreas undergo astonishingly few clinically significant changes with aging. The relative preservation of overall gastrointestinal function with aging is likely due to the large reserve capacity of this multiorgan system. Further research is needed to define the precise nutritional needs for older adults because simple extrapolation of values from younger adults is now recognized to be insufficient. In addition, it is no longer acceptable to define adequate nutriture in terms of amounts of vitamins needed to maintain serum levels of a nutrient. Further RDAs must consider the functional implications of adequate nutrition. Nutrients in the elderly will

  13. Physiology and physiopathology at CT

    International Nuclear Information System (INIS)

    Although CT is essentially a morphological technique, it should theoretically enable investigation of certain physiological and physiopathological phenomena to be made, for example by the study of (i) CT numbers and (ii) the nature and evolution of enhancements. Intravenous injection of iodine contrast agent increases the attenuation coefficients of cerebral parenchyma, which is theoretically due only to the enhancement of the vascular compartment and in direct correlation with the cerebral blood volume (CBV). The authors have measured the attenuation coefficients of the blood and the parenchyma at varying times after contrast injection. Two contrast agents with differing osmolarities were studied. Two scanners were used - an ACTA scanner and an ND 8000. Twenty CTs were performed on five patients after a bolus injection of a solution of 38% iodine: sodium ioxithalamate 25.69 g; methylglucamine oxithalamate 51.3 osmolarity 1800 mosmol/12 ml/kg were injected. Leakage of the iodine contrast agent, however, considerably increases the density coefficient of cerebral parenchyma and rules out any accurate measurement of the CBV. CT study of cerebral physiopathology is also discussed. This is dependent on two techniques - measurement of attenuation coefficients and observation of enhancements - neither of which are shown to give results characteristic of any one physiopathology. The application of CT in physiological and physiopathological cerebral phenomena is currently extremely limited. (Auth.)

    Anorexia and Bulimia nervosa are common psychiatric disorders in adolescent girls. In discrepancy to ICD-10 and DSM-IV we would propose the 10th BMI percentile as weight criterium for anorexia nervosa. Both disorders have a high somatic and psychiatric comorbidity; the most severe complication at long term follow-up is osteoporosis. The most prevalent psychiatric disorders are affective disorders, anxiety and obsessive-compulsive disorder and substance abuse. There is undoubtedly a genetic predisposition and a range of general and personal environmental risk factors. Treatment of adolescent eating disorders mostly requires a multimodal approach which consists of several components, e.g. weight rehabilitation, nutritional counselling, individual and family psychotherapy, and treatment of comorbid psychiatric disorders.

  15. Statistical phenomena in particle beams

    International Nuclear Information System (INIS)

    Particle beams are subject to a variety of apparently distinct statistical phenomena such as intrabeam scattering, stochastic cooling, electron cooling, coherent instabilities, and radiofrequency noise diffusion. In fact, both the physics and mathematical description of these mechanisms are quite similar, with the notion of correlation as a powerful unifying principle. In this presentation we will attempt to provide both a physical and a mathematical basis for understanding the wide range of statistical phenomena that have been discussed. In the course of this study the tools of the trade will be introduced, e.g., the Vlasov and Fokker-Planck equations, noise theory, correlation functions, and beam transfer functions. Although a major concern will be to provide equations for analyzing machine design, the primary goal is to introduce a basic set of physical concepts having a very broad range of applicability

    This textbook provides a thorough presentation of the phenomena related to the transport of mass, momentum and energy.  It lays all the basic physical principles, then for the more advanced readers, it offers an in-depth treatment with advanced mathematical derivations and ends with some useful applications of the models and equations in specific settings. The important idea behind the book is to unify all types of transport phenomena, describing them within a common framework in terms of cause and effect, respectively represented by the driving force and the flux of the transported quantity. The approach and presentation are original in that the book starts with a general description of transport processes, providing the macroscopic balance relations of fluid dynamics and heat and mass transfer, before diving into the mathematical realm of continuum mechanics to derive the microscopic governing equations at the microscopic level. The book is a modular teaching tool and can be used either for an introductory...

  17. Targeting the adolescent male.

    Science.gov (United States)

    Pitt, E

    1986-01-01

    The National Urban League regards too early parenting among adolescents as an issue requiring high level, active attention from all segments of the Black community. Poverty, single parent households and adolescent pregnancies are not exclusively female problems. The role that males play has been missing from too many studies of these phenomena. In light of the fact that most sexual activity is male initiated, and most sexual behavior is male influenced, it becomes clear that there will be no resolution of the problem of teenage pregnancy without directing greater attention to the male. The issue of male responsibility is skirted too often due to parental pride on the part of mothers and fathers when their male children seek sexual relations with female partners. It is viewed as a sign that they are developing sexually within the norm. This is especially true, in many instances, in female headed households where the mother is concerned that she may not be providing her son with an adequate male role model. Sexual activity by female adolescents, however, is generally not condoned. This confusing double standard is further compounded by the disjointed fashion in which American society responds to adolescent sexuality on the whole. Although the home should be the focal point, many parents reluctantly admit an inability to communicate effectively about sex with their pre-adolescent children. Thus, the school, church, community and social agencies have all been enlisted in this task. The National Urban League's initiative in this area is expected to have significant impact on the course of adolescent sexuality and reproductive responsibility.(ABSTRACT TRUNCATED AT 250 WORDS) PMID:3745498

    All three types of malnutrition - underweight, overweight and micronutrient deficiency - are experienced in countries undergoing a nutrition transition, and they can occur in parallel in one community or even one household. To combat this triple burden of malnutrition, a combination of different strategies will be necessary, including a focus on food-based strategies that promote the consumption of a wide range of foods across nutritionally distinct food groups. In addition to a literature review, data from our own nutrition studies in both Tanzania and Kenya are presented in this paper. The literature review revealed an average of 10% of children in urban areas of Kenya and Tanzania with overweight and obesity, which is an alarming trend, and it is suggested that interventions need to start not only at school but also with adolescent girls and pregnant women to target the '1,000-day window'. From own study data, dietary patterns were generated that included a 'purchase' pattern dominated by bought and processed foods, indicating a possible nutrition transition even in the rural areas of both countries. Vegetable and especially fruit consumption was low in both countries. In addition, in Kenya, study participants exceeded the suggested maximum level of sugar consumption per day, which will most likely contribute to increasing levels in overweight and obesity prevalence and other noncommunicable diseases in general. As sugar was mainly consumed in combination with black tea, next to eating habits, changing drinking habits is also an important part of the nutrition transition and needs to receive more attention. A 'healthy eating at school and at home strategy' is suggested, which needs the support of both schools and parents/caregivers. In general, to take countermeasures against the negative trends of nutrition transition, joint efforts from all players in the field - not only those in nutrition, health and medicine, but also those in education and agriculture
