    A strong association between stress in pregnancy and small head circumference in infants at birth was reported in 1994. This important finding has never been replicated. In a follow-up study of 4211 participants with singleton pregnancies, information on life events was collected twice during...... pregnancy and head circumference measured shortly after birth following standard procedures. No association was found between experienced or perceived stress as a result of life events during pregnancy and head circumference in the infants. In conclusion, stress in pregnancy may influence foetal brain...

    Although the body length and weight of an infant are related to head circumference, little research on ASDs has examined these factors. Our study compared the head circumferences of neonates who were later diagnosed with ASD with a control group. Additional comparisons on morphological disproportions at birth included the head circumference-to-height and head circumference-to-weight ratios. We recruited 422 children with ASD and 153 typically developing children. Head circumference, body length and weight at birth were collected and standardized as percentile scores according to gestational age and gender. Our results revealed that genuine macrocephaly was significantly higher in children with other pervasive developmental disorders compared with the control group. This difference was not observed with regard to genuine microcephaly. Relative macrocephaly and relative microcephaly were significantly more frequent in children with autism disorder compared with the control group with regard to body length. The differences in relative macrocephaly and microcephaly, as well as in other parameters, between diagnostic subgroups suggest that the presence of several neurological mechanisms plays a role in the later expression of different phenotypes. An increased head circumference-to-body length ratio in newborns may be a factor to follow that could be related to ASD. ©2013 Foundation Acta Paediatrica. Published by John Wiley & Sons Ltd.

    We aimed to assess the effects of exposure to tobacco smoke, alcohol and illegal drugs during early pregnancy on the head circumference (HC) at birth of otherwise healthy neonates. A follow-up study from the first trimester of pregnancy to birth was carried out in 419 neonates. An environmental reproductive health form was used to record data of substance exposure obtained during the first obstetric visit at the end of the first trimester. A multiple linear regression model was created for this purpose. Alcohol intake during pregnancy and medical ionizing radiation exposure were the most significant predictors of HC. The mothers' alcohol consumption increased with the mothers' and fathers' education level, net family income and fathers' alcohol consumption. In contrast, maternal smoking decreased with increasing mothers' and fathers' education level and net family income. About 13% of the surveyed embryos were exposed to illegal drugs. Mild to moderate alcohol consumption diminishes the at-birth HC of theoretically healthy newborns in a linear form. There was no threshold dose. We perceived a need for increasing the awareness, and for training, of health care professionals and parents, in regard to risks of alcohol consumption and for recommending abstinence of these substances in both parents during pregnancy. It should also be remembered that medical ionizing radiation should be performed only during the first half of the cycle in fertile women. We think that our study has an important social impact as it affords data for implementing policies for promoting "healthy pregnancies".

    Full Text Available Arginine is a constituent of proteins and a precursor for polyamines and nitric oxide, and is essential for placentation, angiogenesis, and growth. Maternal plasma arginine concentrations are found to be lower in pregnancies complicated by fetal growth restriction, and arginine supplementation in later pregnancy is reported to increase birth weight. We measured arginine and the metabolites asymmetric dimethylarginine (ADMA and symmetric dimethylarginine (SDMA in the amniotic fluid obtained in pregnancy weeks 13 to 15 from 363 pregnancies with a documented normal outcome and related the concentrations to birth weight, length, and head circumference. Arginine was higher in the amniotic fluid from female (mean 40.8 (SD 10.6 µmol/L compared to male fetuses (37.4 (SD 11.2 µmol/L, p = 0.003. Despite the gender difference, arginine in the amniotic fluid from gestational weeks 13–15 was the strongest predictor for birth weight, length, and head circumference. ADMA was a strong predictor for birth weight and length, SDMA for birth weight, while Arg/ADMA and Arg/SDMA only predicted head circumference in multiple linear regression models. Due to increased arginine demands, pregnancy is considered a state of relative arginine deficiency. Our findings reflect the importance of a good maternal arginine status in early pregnancy, an observation that should be evaluated in an intervention study.

    In the evaluation of the growth of head circumference (HC), charts depicting normal growth are of paramount importance. Current Finnish HC growth charts are based on data from only 130 children born 1953-1964. As a secular trend in HC growth has been reported, we updated the HC charts using a large sample of contemporary HC data. Mixed cross-sectional HC data of 19,715 healthy subjects aged 0-7 years were collected from primary health care providers. References for HC for age and HC/height ratio for age were fitted using generalized additive models for location, scale, and shape (GAMLSS). Increased HC for age was seen particularly after 2 years of age in both genders compared to the 1953-1964 reference. The SD for HC was remarkably larger in the 1953-1964 reference. The proportion of 1986-2008 reference subjects exceeding the +2 SD limit of the 1953-1964 reference was much bigger than the proportion below -2 SD. Because of the secular change in HC growth, the HC reference has to be renewed periodically. The new Finnish reference for HC for age should be implemented for monitoring HC growth of children in Finland.

    Access to updated and accurate standards for local populations is important for the interpretation of body measurements in neonates and may have an impact on the doctor's recommendations for monitoring early childhood development. to present individual mean values for the most prevalent body measurements (i.e. birth body length (BBL), birth body weight (BBW) and birth head circumference (BHC)) in neonates and compare them to the duration of pregnancy. The measurements (BBL, BBW and BHC) were collected and analyzed from over 27,000 neonates born in a single center. All women with single pregnancies with gestation ranging from 33 to 42 weeks were included in the study. Mean values and statistically significant standard deviation values from population standards of BBL, BBW, and BHC were evaluated for neonates that were born between the 33rd and 42nd week of gestation. Analysis was conducted for the lower limit (10th percentile), average (50th percentile) and upper limit (90th percentile). This was the first time in Polish literature when population standards were presented for three body meas-urements of neonates. With the size of the cohort, these standards can be successfully implemented into routine clinical practice, especially for screening children with body size deficits.

    Full Text Available Introduction: Head circumference (HC measurement is one of the important parameter for diagnosis of neurological, developmental disorders and dysmorphic syndromes. Recognition of different disorders requires an understanding of normal variation for HC size, in particular, in infancy period with most rapid growth of the brain. Because of international and interracial standard chart differences about anthropometric indices, some differences from local to local, generation to generation and changes in ethnic mix of population and socioeconomic factors, periodic revolution of HC size is suggested. The aims of our study were presenting local HC standard for an Iranian infant population and comparison with the American national center of health statistics (NCHS charts accepted by WHO. Methods: 1003 subjects aged from birth to 24 months apparently healthy normal children enrolled randomly in this cross sectional study. HC size were measured and recorded. Tables and graphs were depicted by Excel Microsoft Office 2007. We use two tailed t-student test for statistical analysis. Results: The mean of HC size in boys was larger than girls. The curves were followed a similar pattern to NCHS based on a visual comparison. Overall our subjects in both sexes at birth time had smaller HC size than NCHS. In other ages our children had larger HC size than those of NCHS. Conclusion: Because of international and interracial difference of HC size. We recommend in each area of the world, local anthropometric indices are constructed and used clinically. In addition more extensive and longitudinally design comprehensive studies is suggested.

  10. Mid-arm circumference and mid-arm/head circumference ratio in term newborns

    Directory of Open Access Journals (Sweden)

    Bettina Barbosa Duque Figueira

    Full Text Available CONTEXT: Mid-arm circumference of the newborn is strongly associated with birth weight and is a very good indicator of low and insufficient birth weight. However, there are few Brazilian studies on the relationship between mid-arm and head circumferences and, thus, this does not form part of the routine evaluation for newborns. OBJECTIVES: To establish the mid-arm circumference and mid-arm/head circumference ratio in a population of term newborns. TYPE OF STUDY: Cross-sectional study carried out between June 1997 and August 1999. SETTING: Hospital Maternidade Leonor Mendes de Barros, São Paulo. PARTICIPANTS: Term newborns (66 males and 65 females of appropriate growth for gestational age, whose mothers were healthy, were included in the study. MAIN MEASUREMENTS: Arm circumference, arm circumference/head circumference ratio, birth weight and gestational age were measured within 48 hours of birth. Data were considered significant when p < 0.01. RESULTS: The mean values for the mid-arm circumference were 10.76 cm (standard deviation, SD = 0.68 for females and 10.76 (SD = 0.81 for males. The mean value for the mid-arm/head circumference ratio was 0.31 (SD = 0.02 for both sexes. Mid-arm circumference values were significantly related to birth weight and gestational age, whereas mid-arm/head circumference ratio was related only to birth weight. CONCLUSIONS: Mid-arm circumference and mid-arm/head circumference ratio values were established for the studied population. It was possible to obtain curves for both mid-arm circumference and mid-arm/head circumference ratio in relation to birth weight. However, for mid-arm circumference, it was only possible to obtain curves in relation to gestational age. The use of the regression curves did not seem powerful enough to predict the mid-arm circumference and mid-arm/head circumference ratio in this population of term newborns. There were no gender differences for either of the measurements studied.

    Birth size curves are needed for clinical and epidemiological purposes. We constructed birth weight (BW), length (BL), and head circumference (BHC) references, assessed effects of twinness and parity, and defined cut-off points for small, appropriate, and large for gestational age. Birth register data of all 753,036 infants born in 1996-2008 in Finland were cleaned to create references reflecting optimal intrauterine growth. The final data included 533,666 singletons and 15,033 twins (median gestation weeks (gws) 40.0 and 37.1, respectively, 41.6% primiparous). Sex-specific BW, BL, and BHC references were constructed from 23 to 43 gws separately for singletons and twins born to primiparous or multiparous mothers. GAMLSS method was used for modelling. In singletons from 36 gws onwards, increased BW and BL were observed in comparison to previous reference from 1979-1983. Twins diverged from singletons from 30 gws onwards. At 37.0 gws, mean BW was 400 g lower and mean BL 1.2 cm shorter than in singletons. From 30 gws onwards, birth size was larger in infants of multiparous than primiparous mothers. Population-based birth size references are available for the evaluation of birth size. Accounting for plurality and parity improves the accuracy of birth size evaluation.

    In recent years more and more genetic defects along the GHRH-GH-IGF-I axis have been reported. Mutations of the IGF-I receptor (R) are a rare abnormality of whom only the heterozygote progenies survive. To summarize, from the literature, data on birth length, weight and head circumference of neonates with IGF-I-R mutations, and to correlate the data with that of other types of mutations in the GH/IGF-I axis. Sixty seven neonates from 24 published articles were included and forty seven different mutations of the IGF-I (R) located on chromosome 15 have been identified. Mean (±SD) birth length (BL), available for 26, (10 M, 16F) neonates with a gestational age of 34-41weeks, was 44.2±4cm; one was premature (30cm at 31 weeks). There was a significant correlation between birth length and gestational age (GA) r=0.71 (p>.001). Mean birth weight (BW) of 41 neonates (18M, 23F) was 2388±743gr. Two premature neonates weighed 650gr and 950gr respectively. The BW correlated significantly with gestational age, (males: r=0.68; p=0.007, females: r=0.49; p=0.024). The BMI of 25 neonates ranged from 6 to 13. In 22 records marked microcephaly was ascertained or stated. Nine of 16 mothers were short (133 -148cm), m±SD = 150.5±7.3cm.

    Persistently high rates of cesarean deliveries are cause for concern for physicians, patients, and health systems. Prelabor assessment might be refined by identifying factors that help predict an individual patient's risk of cesarean delivery. Such factors may contribute to patient safety and satisfaction as well as health system planning and resource allocation. In an earlier study, neonatal head circumference was shown to be more strongly associated with delivery mode and other outcome measures than neonatal birthweight. In the present study we aimed to evaluate the association of sonographically measured fetal head circumference measured within 1 week of delivery with delivery mode. This was a multicenter electronic medical record-based study of birth outcomes of primiparous women with term (37-42 weeks) singleton fetuses presenting for ultrasound with fetal biometry within 1 week of delivery. Fetal head circumference and estimated fetal weight were correlated with maternal background, obstetric, and neonatal outcome parameters. Elective cesarean deliveries were excluded. Multinomial regression analysis provided adjusted odds ratios for instrumental delivery and unplanned cesarean delivery when the fetal head circumference was ≥35 cm or estimated fetal weight ≥3900 g, while controlling for possible confounders. In all, 11,500 cases were collected; 906 elective cesarean deliveries were excluded. A fetal head circumference ≥35 cm increased the risk for unplanned cesarean delivery: 174 fetuses with fetal head circumference ≥35 cm (32%) were delivered by cesarean, vs 1712 (17%) when fetal head circumference cesarean delivery by an adjusted odds ratio of 1.75 (95% confidence interval, 1.4-2.18) controlling for gestational age, fetal gender, and epidural anesthesia. The rate of prolonged second stage of labor was significantly increased when either the fetal head circumference was ≥35 cm or the estimated fetal weight ≥3900 g, from 22.7% in the total

    To determine whether large head circumference increases the risk of vacuum extraction failure. This EMR-based study included all attempted vacuum extractions performed in a tertiary center between January 2010 and June 2015. All term singleton live births were eligible. Cases were divided into four groups: head circumference > 90th percentile both with birth weight > 90th percentile and 90th and < 90th percentile. Risk of failed vacuum extraction was compared among these groups. Other neonatal and maternal parameters were also evaluated as potential risk factors. Multinomial multivariable regression provided adjusted odds ratio for vacuum extraction failure while controlling for potential confounders. During the study period 48,007 deliveries met inclusion criteria, of which 3835 had an attempt at vacuum extraction. We identified 215 (5.6%) cases of vacuum extraction failure. The adjusted odds ratios (aOR) for vacuum extraction failure in cases of large fetal head circumference was 2.31 (95% CI, 1.7-3.15, p < 0.001). Primiparity, prolonged second stage and occipito-posterior presentation were also found to be significant risk factors for failed vacuum extraction. In this study we found that large head circumference was associated with vacuum extraction failure rather than high birth weight.

    Full Text Available BackgroundAltered fetal growth is known to be associated with allergic disease. Specifically, increased head circumference at birth has been linked to asthma and elevated IgE. However, few studies have examined a link between early fetal anthropometry and allergic disease. The aim of this study was to examine head circumference at mid-gestation in children diagnosed with allergy.MethodsThis was a retrospective cohort study, comprising pregnancies delivered between 10/2006 and 9/2010 at Nepean Hospital, Australia. Exclusion criteria were illegal drug use, alcohol consumption, gestation <35 weeks and gestational hypertension. Pregnancy data was sourced from the Nepean Obstetric Database. Atopic diseases (asthma, atopic dermatitis and IgE-mediated food allergy were assessed by questionnaire, at age 1-5 years. Infants from pregnancies with completed questionnaires, who also had a mid-gestation ultrasound scan, were included (N=121. Multiple logistic regression techniques were used to model head circumference against the development of allergies.ResultsSmaller head circumference at mid-gestation was associated with an increased odds of allergic disease in children aged 1-5 years. A 1 mm smaller head circumference was associated with a 7% increased chance of allergies being later diagnosed, adjusted for gestation (95% CI: 1%-14%, p=0.036. Head circumference at mid-gestation was also inversely correlated with the presence of multiple atopic disease.ConclusionsSmaller mid-gestational head circumference is associated with early childhood allergic disease, which suggests fetal programming of allergic disease occurs before mid-gestation. This suggests that mediators such as brain-derived neurotropic factor may be dysregulated early in utero in a milieu, which also predisposes to atopic disease.

    To provide head circumference references for school-aged children in western Romania, and compare them with references from other European countries. A total of 2742 children, aged 6-19 years, from Timis county, were examined by medical students, between February 2010-June 2011. Head circumference references were constructed by Cole's LMS method with LMSChartMaker software. The Romanian 3rd, 50th and 97th percentiles for head circumference were compared with recent references from Belgium and Germany. Generally, boys show significantly larger head circumference compared to girls at any age. The head circumference increments between 6 and 19 years are references from Romania to those from Germany and Belgium, we found lower median head circumference in Romanian boys and girls, that could be explained by a taller stature of boys and girls in Germany and Belgium compared to Romania.

    Brain volume progressively decreases with an increase in atrophy, and the brain becomes more susceptible to degenerative brain diseases such as Alzheimer's disease. Metabolic syndrome has also been associated with an increased risk of cognitive decline in the elderly. In this study, we aimed to examine the effects of head circumference and metabolic syndrome on cognitive decline. This study was part of a longitudinal study conducted on Koreans aged 60 years or older. We analyzed a final sample of 596 Korean participants with complete baseline and 2-year follow-up data. The cognitive function of the subjects was assessed using the Korean version of the Mini Mental State Examination (MMSE). Head circumference was measured from the glabella to the occipital protuberance using a measuring tape. Metabolic syndrome was defined according to the NCEP-ATP III standards. Central obesity was assessed on the basis of waist-circumference values, in accordance with the World Health Organization Western Pacific Region report on Asians. We used a longitudinal factorial design in which the MMSE score was the dependent variable, and head circumference and metabolic syndrome were considered as factors. After adjusting the results for age, gender, education, height, weight, baseline MMSE, and number of follow-up years, we observed that smaller head circumference and the presence of metabolic syndrome were independently associated with rapid cognitive decline. All these findings suggest that smaller head circumference and the presence of metabolic syndrome have additive effects on cognitive decline. Copyright 2009 S. Karger AG, Basel.

    2013-04-01

    To determine whether asymmetric macrosomia (disproportionately large body size in comparison to head circumference) could be demonstrated in a population of infants suffering shoulder dystocia during delivery relative to those that did not suffer from shoulder dystocia. A case-control study was conducted as a retrospective chart review over 3 years at a large maternity hospital in an urban setting. Among infants over 4,000 g, those that suffered from shoulder dystocia during delivery had a smaller mean head circumference than infants of a similar size that did not suffer from shoulder dystocia. A statistically significant difference was also present when cases of documented gestational diabetes were excluded. Asymmetric macrosomia is more likely to be present in a population of infants who suffered shoulder dystocia during delivery. This knowledge could be used in designing tools to predict which pregnancies are at highest risk for shoulder dystocia during delivery.

    This study aimed to investigate whether height, weight, head circumference and/or relationships between these factors are associated with gross motor milestone acquisition in children with achondroplasia. Population-based data regarding timing of major gross motor milestones up to 5 years were correlated with height, weight and head circumference at birth and 12 months in 48 children with achondroplasia born in Australia and New Zealand between 2000 and 2009. Although as a group children with achondroplasia showed delayed gross motor skill acquisition, within group differences in height, weight or head circumference did not appear to influence timing of gross motor skills before 5 years. The exception was lie to sit transitioning, which appears likely to occur earlier if the child is taller and heavier at 12 months, and later if the child has significant head-to-body disproportion. This is the first study to investigate the relationship between common musculoskeletal impairments associated with achondroplasia and timing of gross motor achievement. Identification of the musculoskeletal factors that exacerbate delays in transitioning from lying to sitting will assist clinicians to provide more proactive assessment, advice and intervention regarding motor skill acquisition for this population. © 2013 The Authors.

    Full Text Available Context Milk and dairy products consumed by mothers seem to be effective for fetal and neonatal anthropometric measurements, because they contain various nutrients. Objectives The aim of this study was to systematically review the influence of milk and dairy products consumption by mothers on fetal and neonatal head circumferences. Data Sources Systematic searches were conducted in electronic databases including PubMed/MEDLINE, Scopus, ISI, Ovid, Embase, Medlib, Google Scholar, clinical trials and Cochrane central register of clinical trials. Study Selection All studies that assessed the relationship between milk and dairy products consumption in healthy females during pregnancy and fetal and neonatal head circumferences were included in our systematic review. Finally, seven studies were relevant that included five cohort studies, one cross-sectional study and one randomized clinical trial. Data Extraction This systematic review was performed based on the preferred reporting item for systematic reviews and meta-analysis (PRISMA statement recommendation, and for quality assessment, the Newcastle-Ottawa scale (NOS for cohort studies, the adapted NOS for a cross-sectional study and the Jadad quality assessment score for a randomized clinical trial, were used. Results Seven studies that comprised of more than 50000 pregnant females were included in this review. One cohort study, one cross-sectional study and one randomized controlled trial study showed that milk or dairy products consumption by pregnant mothers was not associated with neonatal birth head circumference, while three cohort studies reported that maternal milk or dairy products intake had a positive effect on neonatal birth head circumference. Two cohort studies showed that there was no relationship between maternal milk or dairy products consumption and fetal head circumference while a cross-sectional study reported that there was a positive relationship between milk or dairy products

    The head circumference growth reference charts for children in China are presently based on urban children. However, the references may not apply to rural children because of the differences between urban and rural areas, such as economy, culture, and dietary habits. Our objective was to provide a reliable continuous set of head circumference growth reference charts for male and female children less than 7 years of age in Chinese rural areas. Children in our study were identified by multistage stratified cluster sampling from rural areas of 10 provinces in China. Questionnaire survey and anthropometric measurements were conducted in data collection. Head circumference was measured with a nonelastic tape on a line passing over the glabella and posterior occipital protrusion in children. We compared the fiftieth percentile of our cross-sectional data with the data of Chinese cities, World Health Organization, and the United States. A total of 95,904 children (48,722 boys and 47,182 girls) were included in the study. We present age- and sex-appropriate head circumference growth charts younger than 7 years for Chinese rural areas. The head circumference percentiles of the children in rural China are much smaller than the children in Chinese urban areas, World Health Organization, and the US percentiles after 2 years old. Head circumference percentiles can be applied in growth monitoring, but current head circumference growth references promulgated in urban China may not be suitable for rural areas in China. Providing head circumference growth reference charts for rural Chinese children who are younger than 7 years old is very important. Copyright © 2014 Elsevier Inc. All rights reserved.

    Full Text Available Abstract Objectives: to describe altered intrauterine ultrasound, analyze fetal head circumference (HC growth and neonates' outcomes among presumed cases of congenital Zika syndrome in Brazil. Methods: 30 women were included in the study with suspected history of Zika virus (ZIKV infection during pregnancy and fetal's brain altered on ultrasound diagnosis. Sociodemographic and obstetric characteristics, prenatal altered ultrasounds, HC and other perinatal outcomes have been described. The relation between HC and gestational age was analyzed by using random regression effects based on polynomials fractions. The Z test was calculated to determine an instant variant mean rate of the HC for each gestational age. Results: the mean gestational age of the ultrasound diagnosis was 33.3 + 4.7 weeks and HC at birth was 28.9 + 1.6 cm. The main altered brain ultrasound was microcephaly (96.7%. The analysis of the fetal head circumference showed an estimated increase of the average HC, as to gestational age, it did not occur in a linear form. The instant HC variation rate increased according to gestational age (p<0,001. Conclusions: Fetal's main morphological alteration was microcephaly, observing an increase in the head circumference according to gestational age in a non-linear form and the variation decreased with gestational age.

    Previous studies have shown strong genetic influence to head circumference (HC), but still little is known on the development of genetic etiology of HC in infancy, especially in non-Caucasian populations. Thus, we decided to analyze the genetics of HC growth in Japanese infants. Longitudinal measures of HC were available from birth to 13 months of age in 206 monozygotic and 156 dizygotic complete twin pairs. Genetic modeling for twin data was used. We found only little evidence for sex-specific differences in the genetics of HC and thus analyzed boys and girls together. After 5 months of age the heritability of HC was high, but before that age also a substantial common environmental component was present. Not only strong genetic persistence for HC was found but also a new genetic variation emerged. New environmental variation shared by co-twins affecting HC was found until 3 months of age, and this effect was further transmitted until 1 year of age. HC and its growth are strongly genetically regulated. Largely, the same genetic factors affect the variation of HC at different ages, and new genetic variation emerged during the first year of life. Knowledge on the genetic component in the variation of HC may help to design tools for defining abnormal growth of HC in population-based screenings for related disorders.

    Head circumference in infants has been reported to predict brain size, total grey matter volume (GMV) and neurocognitive development. However, it is unknown whether it has predictive value on regional and subcortical brain volumes. We aimed to explore the relationship between several head circumference measurements since birth and distributions of GMV and subcortical volumes at later childhood. We examined seventy-four, Caucasian, singleton, term-born infants born to mothers randomised to receive fish oil and/or 5-methyltetrahydrofolate or placebo prenatal supplementation. We assessed head circumference at birth and at 4 and 10 years of age and cognitive abilities at 7 years of age. We obtained brain MRI at 10 years of age, on which we performed voxel-based morphometry, cortical surface extraction and subcortical segmentation. Analyses were controlled for sex, age, height, weight, family status, laterality and total intracranial volume. Prenatal supplementation did not affect head circumference at any age, cognitive abilities or total brain volumes. Head circumference at 4 years presented the highest correlation with total GMV, white matter volume and brain surface area, and was also strongly associated with GMV of frontal, temporal and occipital areas, as well as with caudate nucleus, globus pallidus, putamen and thalamus volumes. As relationships between brain volumes in childhood and several outcomes extend into adulthood, we have found that ages between 0 and 4 years as the optimal time for brain growth; postnatal factors might have the most relevant impact on structural maturation of certain cortical areas and subcortical nuclei, independent of prenatal supplementation.

    Objective This study aims to determine if shoulder dystocia is associated with a difference in the fetal abdominal (AC) to head circumference (HC) of 50 mm or more noted on antenatal ultrasound. Study Design A multicenter matched case–control study was performed comparing women who had shoulder dystocia to controls who did not. Women with vaginal births of live born nonanomalous singletons ≥ 36 weeks of gestation with an antenatal ultrasound within 4 weeks of delivery were included. Controls were matched for gestational age, route of delivery, and diabetes status. Results We identified 181 matched pairs. Only 5% of the fetuses had an AC to HC of ≥ 50 mm. The proportion of AC to HC difference of ≥ 50 mm was significantly higher in shoulder dystocia cases (8%) than controls (1%, p = 0.002). With multivariate regression, the three significant factors associated with shoulder dystocia were AC to HC ≥ 50 mm (odds ratio [OR], 7.3; confidence interval [CI], 1.6–33.3; p = 0.010), femur length (OR, 1.1; CI, 1.0–1.2; p = 0.002), and induced labor (OR, 1.8; CI, 1.1–3.1; p = 0.027). Conclusion A prenatal ultrasound finding of a difference in AC to HC of ≥ 50 mm while uncommon is associated with shoulder dystocia. PMID:26495163

    Macrocephaly and brain overgrowth have been associated with autism spectrum disorder. We performed a systematic review and meta-analysis to provide an overall estimate of effect size and statistical significance for both head circumference and total brain volume in autism. Our literature search strategy identified 261 and 391 records, respectively; 27 studies defining percentages of macrocephalic patients and 44 structural brain imaging studies providing total brain volumes for patients and controls were included in our meta-analyses. Head circumference was significantly larger in autistic compared to control individuals, with 822/5225 (15.7%) autistic individuals displaying macrocephaly. Structural brain imaging studies measuring brain volume estimated effect size. The effect size is higher in low functioning autistics compared to high functioning and ASD individuals. Brain overgrowth was recorded in 142/1558 (9.1%) autistic patients. Finally, we found a significant interaction between age and total brain volume, resulting in larger head circumference and brain size during early childhood. Our results provide conclusive effect sizes and prevalence rates for macrocephaly and brain overgrowth in autism, confirm the variation of abnormal brain growth with age, and support the inclusion of this endophenotype in multi-biomarker diagnostic panels for clinical use.

    Background: Synchrony between daily feeding-fasting signals and circadian rhythms has been shown to improve metabolic health in animals and adult humans, but the potential programming effect on fetal growth is unknown. Objective: We examined the associations of the maternal night-fasting interval during pregnancy with offspring birth size and adiposity. Methods: This was a cross-sectional study of mother-offspring dyads within the Growing Up in Singapore Towards healthy Outcomes (GUSTO) cohort. For 384 mothers aged 30.8 ± 4.8 y (mean ± SD), the night-fasting interval at 26-28 wk of gestation was determined from a 3-d food diary based on the average of the fasting duration at night (1900-0659). Offspring birth weight, length, and head circumference were measured and converted to weight-for-gestational age (GA), length-for-GA, and head circumference-for-GA z scores, respectively, by using local customized percentile charts. The percentage of neonatal total body fat (TBF) was derived by using a validated prediction equation. Multivariable general linear models, stratified by child sex, were performed. Results: The mean ± SD maternal night-fasting interval was 9.9 ± 1.3 h. In infant girls, each 1-h increase in the maternal night-fasting interval was associated with a 0.22-SD (95% CI: 0.05-, 0.40-SD; P = 0.013) increase in birth head circumference-for-GA and a 0.84% (95% CI: 0.19%, 1.49%; P = 0.012) increase in TBF at birth, after adjustment for confounders. In infant boys, no associations were observed between the maternal night-fasting interval and birth size or TBF. Conclusions: An increased maternal night-fasting interval in the late second trimester of pregnancy is associated with increased birth head circumference and TBF in girls but not boys. Our findings are in accordance with previous observations that suggest that there are sex-specific responses in fetal brain growth and adiposity, and raise the possibility of the maternal night-fasting interval as an

    A comparison of fetal ultrasonographic biometric parameters of the head (head circumference - HC, biparietal diameter - BPD) in breech presented fetuses. Ultrasound biometry was performed in accordance with the method presented in the reference tables. In all breech presented fetuses, the HC, BPD and FL (femur length) were measured. High-risk and multiple pregnancies were excluded from the study. A total of 111 ultrasonographic biometries were performed between the 31(st) - 38(th) week of gestation. Fetuses in the breech position had a significantly lower BPD compared to HC and FL. The difference between BPD and HC was 16.2 days (95%Cl 14.3-18.1; p = 0.001). Maternal age at delivery was 20 - 36 years (average 28.1; median 28.0). According to our results, fetuses in the breech position have a significantly lower BPD compared to HC or FL. HC and FL parameters correlate with gestational age. In cases of ultrasonographic biometric discrepancy between BPD and FL, the fetal position should be taken into account. Breech-presented fetuses have an elongated head shape and ultrasound biometrics should evaluate its circumference (HC). It is important to responsibly interpret the results so as not to stress the expecting mother with suspicions of fetal pathology.

    In order to prepare growth references for height, weight, and head circumference for Argentine children with Achondroplasia, 228 children (114 boys) aged 0-18 years attending the Growth Clinic at Hospital Garrahan were measured between 1992 and 2009. Centiles were calculated by LMS, a method for summarizing growth data which adjusts for skewness. Curves for centiles are obtained using the formula: [Formula: see text], where Z (α) is the normal equivalent deviate for tail area α; C100α is the weight or height centile corresponding to Z (α), t is age in years, and L(t) is (skewness)(t), M(t) is median, S (t) is coefficient variation and C(100α) (t) indicates the corresponding values of each curve at age t. Boys and girls centiles for height were similar to USA references in infancy and childhood but lower than that references at adolescence. Final height was 1.7 and 5.1 cm below USA achondroplasia references in girls and boys, respectively. Head circumference centiles were, at all ages, lower than USA references in both genders. Countries need national references for clinical growth assessment of their local population. Likewise, specific local growth references for children with some genetic conditions (such us achondroplasia) are valuable tools for detecting additional conditions affecting growth, for estimating final height and for evaluating the impact of growth-promoting treatments. references presented here can also be used in other countries with similar ethnographics characteristics.

    Published Growth studies from Latin America are limited to growth references from Argentina and Venezuela. The aim of this study was to construct reference growth curves for height, weight, body mass index (BMI) and head circumference of Colombian children in a format that is useful for following the growth of the individual child and as a tool for public health. Prospective measurements from 27 209 Colombian children from middle and upper socio-economic level families were processed using the generalised additive models for location, scale and shape (GAMLSS). Descriptive statistics for length and height, weight, BMI and head circumference for age are given as raw and smoothed values. Final height was 172.3 cm for boys and 159.4 cm for girls. Weight at 18 years of age was 64.0 kg for boys and 54 kg for girls. Growth curves are presented in a ± 3 SD format using logarithmic axes. The constructed reference growth curves are a start for following secular trends in Colombia and are also in the presented layout an optimal clinical tool for health care. ©2015 Foundation Acta Paediatrica.

    To assess the variability in asymmetric growth and its association with neurodevelopment in infants with single ventricle (SV). We analyzed weight-for-age z-score minus head circumference-for-age z-score (HCAZ), relative head growth (cm/kg), along with individual growth variables in subjects prospectively enrolled in the Infant Single Ventricle Trial. Associations between growth indices and scores on the Psychomotor Developmental Index (PDI) and Mental Developmental Index (MDI) of the Bayley Scales of Infant Development-II (BSID-II) at 14 months were assessed. Of the 230 subjects enrolled in the Infant Single Ventricle trial, complete growth data and BSID-II scores were available in 168 (73%). Across the cohort, indices of asymmetric growth varied widely at enrollment and before superior cavopulmonary connection (SCPC) surgery. BSID-II scores were not associated with these asymmetry indices. In bivariate analyses, greater pre-SCPC HCAZ correlated with higher MDI (r = 0.21; P = .006) and PDI (r = 0.38; P SCPC with higher PDI (r = 0.15; P = .049). In multivariable modeling, pre-SCPC HCAZ was an independent predictor of PDI (P = .03), but not MDI. In infants with SV, growth asymmetry was not associated with neurodevelopment at 14 months, but pre-SCPC HCAZ was associated with PDI. Asymmetric growth, important in other high-risk infants, is not a brain-sparing adaptation in infants with SV. Clinicaltrials.gov: NCT00113087. Copyright © 2016 Elsevier Inc. All rights reserved.

    To present valid head circumference (HC) percentiles from early infancy to 18 years and to compare them with percentiles currently used in Germany by Prader, as well as to international WHO and CDC references. Nationally representative sample of 17,158 children and adolescents aged 0.25-17.98 years (KiGGS study 2003-2006) with standardized HC measurement. HC references were created using Cole's LMS method. The median growth of HC is largest in the first year of life. Adult HC is reached at age 16 years in girls, while in boys, HC growth continues through age 17 years and adult HC have to be derived from future KiGGS follow-up examinations. KiGGS percentiles are quite similar from early infancy to early school age compared to older Prader references, but higher thereafter (maximum difference of median HC: girls 1.4 cm, boys 0.9 cm). KiGGS percentiles are also higher than WHO and CDC percentiles over most of the compared age range, but differences are less pronounced compared to Prader. The KiGGS HC references presented here for boys and girls aged 4 months through 17 years are more valid than currently used German references. Because of the similarity of KiGGS and the currently used reference by Prader in early infancy, the currently used Prader reference for 0-4 months could complement KiGGS to cover the entire age range from birth to the end of adolescence. © 2011 The Author(s)/Acta Paediatrica © 2011 Foundation Acta Paediatrica.

    The purpose of this study was to investigate the associations between birth weight, chest circumference, and lung function in preschool children from e-waste exposure area. A total of 206 preschool children from Guiyu (an e-waste recycling area) and Haojiang and Xiashan (the reference areas) in China were recruited and required to undergo physical examination, blood tests, and lung function tests during the study period. Birth outcome such as birth weight and birth height were obtained by questionnaire. Children living in the e-waste-exposed area have a lower birth weight, chest circumference, height, and lung function when compare to their peers from the reference areas (all p value <0.05). Both Spearman and partial correlation analyses showed that birth weight and chest circumference were positively correlated with lung function levels including forced vital capacity (FVC) and forced expiratory volume in 1 s (FEV 1 ). After adjustment for the potential confounders in further linear regression analyses, birth weight, and chest circumference were positively associated with lung function levels, respectively. Taken together, birth weight and chest circumference may be good predictors for lung function levels in preschool children.

Cross-sectional factorial design in which Korean version of Mini Mental State Examination (K-MMSE) score was the dependent variable with ApoE4 status as one factor and HC as the other. A longitudinal cohort study of the Korea Health 21 R&D Project Clinical Research Center for Dementia. A total of 1,902 Koreans (599 men and 1303 women) aged over 60 years. Cognitive function was assessed by the K-MMSE. HC and ApoE genotyping were carried out on all subjects. The HC was correlated with the K-MMSE scores (r = 0.22, df = 1,525, p MMSE was observed after adjusting for the age, sex, educational level, height, and weight (F = 2.527, df = 4, 1, 364, p = 0.039). A test of simple main effect according to ApoE status showed that, in the ApoE epsilon 4(-) group, the mean of K-MMSE between HC quintile was not different (F = 0.517, df = 4, 1,148, p = 0.723). But in the ApoE epsilon 4(+) group, the mean of K-MMSE between HC quintile was significantly different. (F = 4.163, df = 4, 211, p = 0.003). All these findings suggest the possibility that the presence of ApoE epsilon 4 affects cognitive function only when the brain reserve is low. In other words, these findings support the structural "brain reserve hypothesis," and the effects are more pronounced in genetically predisposed individuals.

    Previous growth references for Norwegian children were based on measurements from the 1970s and 1980s. New reference data, collected through the Bergen Growth Study and the Medical Birth Registry of Norway, are presented as LMS values. A cross-sectional sample of children aged 0-19 years in stratified randomized design measured in 2003-2006 as a part of the Bergen Growth Study (n = 7291) and birth data of children born in 1999-2003 from the Medical Birth Registry of Norway (n = 12 576) was used to estimate the new references by the means of the LMS method. Measurement reliability was assessed by test-rest studies. New references were constructed for length/height, weight, body mass index (BMI) and head circumference. Length/height and weight for children aged 0-4 years were similar to previous Norwegian references, but mean height increased up to a maximum of 3.4 cm in boys and 2.5 cm in girls during the pubertal years. Mean height was similar to (or slightly higher) in comparison with other recent European references. Reliability of the measurements compared well with published estimates. Because of the observed secular trends in growth, it is advised to use the new references, which have been endorsed by the Norwegian Department of Health.

    The evaluation of tools to accurately identify low birth weight (LBW) and/or premature newborns in resource-limited countries is a research priority. We explored the use of foot length, chest circumference, and mid-upper arm circumference (MUAC) measured within 24 h as diagnostic tools for identifying newborns who are LBW, premature, or both; and compared measurements taken at birth with those taken at five days of age. An observational study was undertaken in Hoa Binh Province General Hospital, Vietnam, in ethnic minority newborns. Birth weight, foot length, chest circumference, and MUAC were measured within 24 h of birth and in a subset of 200, were repeated on day five of life. Gestational age was estimated using the New Ballard Score. Receiver Operating Characteristic curves and optimal cut-points (the point with the highest sensitivity and specificity where the sensitivity was at least 0.8) were calculated, for predicting prematurity, LBW, and both. Measurements within 24 h and at five days of life were compared. 485 newborns were recruited. Chest circumference and MUAC measured within 24 h of birth were found to be highly predictive of LBW (both yielding area under the curve [AUC] of 0.98, 95% confidence interval [CI] 0.96-0.99), and performed marginally better than foot length (AUC 0.94, 95%CI 0.92-0.96). The optimal cut-points for measurements within 24 h of birth were ≤ 7.4 cm for foot length; ≤ 30.4 cm for chest circumference; and ≤ 9.0 cm for MUAC. There was statistical evidence that anthropometric measurements taken within 24 h of birth were higher than measurements on day five (p<0.02 for all anthropometric measurements) but the magnitude of these differences was small (at most 2mm). All measurements taken within 24 h of birth were good predictors of LBW, prematurity and both. Differences in measurements taken within 24 h and on day five were not clinically relevant. Further research will ensure that the application of these measures is reliable

    Full Text Available The evaluation of tools to accurately identify low birth weight (LBW and/or premature newborns in resource-limited countries is a research priority. We explored the use of foot length, chest circumference, and mid-upper arm circumference (MUAC measured within 24 h as diagnostic tools for identifying newborns who are LBW, premature, or both; and compared measurements taken at birth with those taken at five days of age.An observational study was undertaken in Hoa Binh Province General Hospital, Vietnam, in ethnic minority newborns. Birth weight, foot length, chest circumference, and MUAC were measured within 24 h of birth and in a subset of 200, were repeated on day five of life. Gestational age was estimated using the New Ballard Score. Receiver Operating Characteristic curves and optimal cut-points (the point with the highest sensitivity and specificity where the sensitivity was at least 0.8 were calculated, for predicting prematurity, LBW, and both. Measurements within 24 h and at five days of life were compared.485 newborns were recruited. Chest circumference and MUAC measured within 24 h of birth were found to be highly predictive of LBW (both yielding area under the curve [AUC] of 0.98, 95% confidence interval [CI] 0.96-0.99, and performed marginally better than foot length (AUC 0.94, 95%CI 0.92-0.96.

    Full Text Available Low Birth Weight (LBW is one of the major risk factor for death in early life. However, little is known about predictors of LBW in sub-Saharan Africa. Therefore, the aim of this study was to measure the incidence and determinants of LBW in a rural population of Ethiopia.An observational cohort study on pregnant women was conducted from December 2009 to November 2010. During the study period 1295 live birth were registered and the weights of 956 children were measured within 24 hours after birth. Socio-demographic, economic, maternal and organizational factors were considered as a predicators of LBW, defined as birth weight below 2500g. Logistic regression was used to analyze the data, odds ratio (OR and confidence intervals (CI are reported.The incidence of LBW was 28.3%. It is significantly associated with poverty [OR 2.1; 95% CI: 1.42, 3.05], maternal Mid Upper Arm Circumference (MUAC less than 23 cm [OR 1.6; 95% CI: 1.19, 2.19], not attending ANC [OR 1.6; 95% CI: 1.12, 2.28], mother's experience of physical violence during pregnancy [OR 1.7; 95% CI: 1.12, 2.48], and longer time to walk to health facility [OR 1.6; 95% CI: 1.11, 2.40].The incidence of LBW was high in Kersa. Babies born to women who were poor, undernourished, experienced physical violence during pregnancy and who had poor access to health services were more likely to be LBW in this part of the country. In this largely poor community where ANC coverage is low, to reduce the incidence of LBW, it is essential to improve access for maternal health care. The involvement of husbands and the community at large to seek collective action on LBW is essential.

    Appropriate fetal brain growth depends upon the cerebral blood flow (CBF). Different congenital heart defects (CHDs), due to the difference in anatomy and physiology, alter the intrauterine CBF. Thus, variable brain growth is expected in different CHDs that is reflected by variability in the head circumference (HC) at birth. The present study was carried out to compare the HC of babies born with transposition of great arteries (TGA) and hypoplastic left heart syndrome (HLHS) in comparison to normal control. The data on the HC of neonates with TGA and HLHS were extracted from the computer database then compared with the control group. During the period from January 1996 to December 2003, a total of 7396 neonates were admitted, out of which 639 (8.6%) were admitted with the diagnosis of the CHD. After correcting for gestational age and non-availability of HC measurements, 236 infants were excluded. Out of the remaining 403 term appropriate for gestational age (AGA) infants, 46 had TGA while 28 had HLHS. The control group comprised of a total of 74 term AGA infants. The mean HC for the control group was noted to be 34.4 +/- 1.7 centimeters (cms), 33.7 +/- 1.5 cms for TGA while it was 32.9 +/- 1.3 cms for HLHS. The head size at birth for newborn with HLHS was significantly smaller than the TGA (p=0.03) and control group (p=0.001). Similarly, HC of TGA group was significantly smaller than the control group (p=0.02). The newborns with TGA and HLHS are found to have significantly small head size at birth. The clinical significance of this finding with respect to the neurodevelopmental outcome and value of early antenatal intervention to repair these defects remains to be evaluated in further studies.

    Our aim was to investigate the correlations between patterns of head growth and intellectual disability among distinct aetiological presentations of microcephaly. 3,269 head circumference (HC) charts of patients from a tertiary neuropediatric unit were reviewed and 136 microcephalic participants selected. Using the Z-scores of registered HC measurements we defined the variables: HC Minimum, HC Drop and HC Catch-up. We classified patients according to the presence or absence of intellectual disability (IQ below 71) and according to the cause of microcephaly (idiopathic, familial, syndromic, symptomatic and mixed). Using Discriminant Analysis a C-function was defined as C=HC Minimum + HC Drop with a cut-off level of C=-4.32 Z-score. In our sample 95% of patients scoring below this level, severe microcephaly, were classified in the disabled group while the overall concordance was 66%. In the symptomatic-mixed group the concordance between HC function and outcome reached 82% in contrast to only 54% in the idiopathic-syndromic group (P-value=0.0002). We defined a HC growth function which discriminates intellectual disability of microcephalic patients better than isolated HC measurements, especially for those with secondary and mixed aetiologies.

    Emma Pomeroy

    Full Text Available Low birth weight has been consistently associated with adult chronic disease risk. The thrifty phenotype hypothesis assumes that reduced fetal growth impacts some organs more than others. However, it remains unclear how birth weight relates to different body components, such as circumferences, adiposity, body segment lengths and limb proportions. We hypothesized that these components vary in their relationship to birth weight.We analysed the relationship between birth weight and detailed anthropometry in 1270 singleton live-born neonates (668 male from the Mater-University of Queensland Study of Pregnancy (Brisbane, Australia. We tested adjusted anthropometry for correlations with birth weight. We then performed stepwise multiple regression on birth weight of: body lengths, breadths and circumferences; relative limb to neck-rump proportions; or skinfold thicknesses. All analyses were adjusted for sex and gestational age, and used logged data.Circumferences, especially chest, were most strongly related to birth weight, while segment lengths (neck-rump, thigh, upper arm, and especially lower arm and lower leg were relatively weakly related to birth weight, and limb lengths relative to neck-rump length showed no relationship. Skinfolds accounted for 36% of birth weight variance, but adjusting for size (neck-rump, thigh and upper arm lengths, and head circumference, this decreased to 10%. There was no evidence that heavier babies had proportionally thicker skinfolds.Neonatal body measurements vary in their association with birth weight: head and chest circumferences showed the strongest associations while limb segment lengths did not relate strongly to birth weight. After adjusting for body size, subcutaneous fatness accounted for a smaller proportion of birth weight variance than previously reported. While heavier babies had absolutely thicker skinfolds, this was proportional to their size. Relative limb to trunk length was unrelated to birth

    The etiology of elbow flexion contracture in children with brachial plexus birth palsy remains unclear. We hypothesized that the long head of the biceps brachii muscle assists with shoulder stabilization in children with brachial plexus birth palsy and that overactivity of the long head during elbow and shoulder activity is associated with an elbow flexion contracture. Twenty-one patients with brachial plexus birth palsy-associated elbow flexion contracture underwent testing with surface electromyography. Twelve patients underwent repeat testing with fine-wire electromyography. Surface electrodes were placed on the muscle belly, and fine-wire electrodes were inserted bilaterally into the long and short heads of the biceps brachii. Patients were asked to perform four upper extremity tasks: elbow flexion-extension, hand to head, high reach, and overhead ball throw. The mean duration of muscle activity in the affected limb was compared with that in the contralateral, unaffected limb, which was used as a control. Three-dimensional motion analysis, surface dynamometry, and validated function measures were used to evaluate upper extremity kinematics, elbow flexor-extensor muscle imbalance, and function. The mean activity duration of the long head of the biceps brachii muscle was significantly higher in the affected limb as compared with the contralateral, unaffected limb during hand-to-head tasks (p = 0.02) and high-reach tasks (p = 0.03). No significant differences in mean activity duration were observed for the short head of the biceps brachii muscle between the affected and unaffected limbs. Isometric strength of elbow flexion was not significantly higher than that of elbow extension in the affected limb (p = 0.11). Overactivity of the long head of the biceps brachii muscle is associated with and may contribute to the development of elbow flexion contracture in children with brachial plexus birth palsy. Elbow flexion contracture may not be associated with an elbow

    Head circumference (HC) is a simple and practical measure of brain size, development and longitudinal measurements of the HC in childhood are an index of brain growth. To determine the effects of long IGF-I deficiency and treatment on HC in patients with Laron syndrome (LS). 20 untreated adult LS patients, aged 48.4±11.2 years and 13 LS patients treated between ages of 5.6±4 to 11.3±3 years were studied. 15 patients with congenital IGHD treated between age 6.1±4 and 13±4 by hGH served as controls. HC was expressed as standard deviation (SD) and Ht as SDS. HC was measured and plotted on Nellhaus charts. Linear height (Ht) was measured by a Harpenden Stadiometer. The mean HC deficit of the adult untreated LS males was -2.9±0.6 SD compared to a Ht deficit of -7.0±1.7 SDS. The HC of the LS adult females was -3.6±1 SD compared to a Ht SDS of -6.9±1.5 (phGH treatment of cIGHD children increased the HC from -2.0±1.8 to 0.3±1.2 SD and the Ht SDS from -4.8±1.6 to 1.6±1.0.

    Full Text Available BackgroundPreeclampsia is associated with fetal growth restriction and low birth weights. Neurotrophins, which mediate neuronal growth and development, are also increased in the placenta and cord blood in preeclampsia. Hence, the aim of this study was to determine whether fetal head growth is altered in preeclampsia, adjusting for growth restriction and other confounding variables.MethodsThis research included a retrospective cohort study, looking at fetal head circumference at birth, plus a case control study examining fetal head circumference at mid-gestation.The head circumference at birth analysis consisted of 14,607 pregnancies (preeclampsia=382, control=14,225, delivered between 7/2006-6/2012 at Nepean Hospital, Australia. Head circumference at birth, in addition to other maternal and fetal variables, was sourced from the Nepean Obstetric Database.The head circumference at mid-gestation study consisted of 756 pregnancies (preeclampsia=248, control=508, delivered within the same data collection period at Nepean Hospital. Head circumference at mid-gestation was retrieved from an earlier ultrasound scan.Exclusion criteria included >1 fetus, illegal drug use, alcohol consumption, chronic or gestational hypertension.Generalised linear models (GLM were used to analyse fetal head circumference in preeclampsia versus controls, adjusting for confounding variables.ResultsHead circumference increased at a greater rate in preeclampsia versus controls, adjusted for gestation, fetal gender, birth weight and length, smoking, maternal BMI and growth restriction. At mid-gestation, there was no difference in head circumference between preeclampsia and controls.ConclusionsFor the first time, this research has suggested increased fetal head growth in preeclampsia, adjusted for confounders. This finding may be explained by altered fetal exposure to neurotrophins in preeclampsia. The long term neurodevelopmental consequences of preeclampsia remains unclear.

    We used longitudinal data from a birth cohort study, the Fragile Families and Child Wellbeing Study, to investigate the links between Head Start and school readiness in a large and diverse sample of urban children at age 5 (N = 2,803; 18 cities). We found that Head Start attendance was associated with enhanced cognitive ability and social competence and reduced attention problems but not reduced internalizing or externalizing behavior problems. These findings were robust to model specifications (including models with city-fixed effects and propensity-scoring matching). Furthermore, the effects of Head Start varied by the reference group. Head Start was associated with improved cognitive development when compared with parental care or other nonparental care, as well as improved social competence (compared with parental care) and reduced attention problems (compared with other nonparental care). In contrast, compared with attendance at pre-kindergarten or other center-based care, Head Start attendance was not associated with cognitive gains but with improved social competence and reduced attention and externalizing behavior problems (compared with attendance at other center-based care). These associations were not moderated by child gender or race/ethnicity. PMID:21244155

    To compare female and male fetuses in terms of intrauterine ultrasound growth measurements (HC--head circumference, BPD--biparietal diameter, FL--femur lenght) depending on gestational age. A prospective study. Department of Obstetrics and Gynecology, Department of Medical Genetics and Fetal Medicine, Department of Preventive Medicine, University Hospital, Olomouc. All ultrasound biometric measurements were performed according to the methodology published with the reference charts. Risk pregnancies, multiple pregnancies and breech presentations were excluded. Fetal HC, BPD and FL were measured in 427 ultrasound examinations at 16-38 weeks. Male fetuses had significantly larger HC and BPD measurements compared to female fetuses and these differences increased with advancing gestation. In the 16-21 week scans estimated difference was (HC + 3.9 days, 3.0% and BPD + 4.1, 3.2%), during the 21-30 week scans (HC + 6.8 days, 4.3% and BPD + 6.9, 4.4%) and in the 31-38 week scans (HC + 12.3 days, 5.6% and BPD + 12.9, 5.9%) for males. Male fetuses had significantly larger HC compared to FL measurements. In the 16-21 week scans, estimated difference was + 2.1 days (95%CI 1.7-2.6, P BPD) measurements compared to female fetuses. These prenatal sex-related differences are established by as early as 16 weeks of gestation and tend to increase with advancing gestational age. In the case of discrepancy finding between head (HC, BPD) and femur lenght (FL) measurements the fetal gender should be taken into account.

    Full Text Available Perinatal mortality remains one of the factors leading to child mortality, even for crude death as a whole. Therefore, good perinatal care is considered to be useful for reducing this mortality. Low birth weight is one of neonatal morbidity cause; previous studies reported correlation between birth weight to several anthropometric measurements and their predictive value. We aimed to evaluate the correlation between birth length, head, chest, abdominal, calf and mid arm circumferences as well as to foot length to birth weight. A cross sectional study was conducted in Adam Malik Hospital Medan between November 1st 1998 to January 31st 1999. All babies without clear moulage, caput succedaneum or cephal hematoma were studied. Birth weight was measured by TANITA weighing scale within the first 24 hours after delivery. Birth length by somatometer and head, chest, abdominal, calf and mid arm circumferences as well as foot length were measured 3 times by using plastic measuring tape. It was evident a positive correlation of birth weight to all such anthropometric measurements with the highest correlation coefficient for calf circumference (r : 0.92. Calf circumference of 9,8 cm is predictor of low birth weight.

    Maternal nutrition has a programming effect on fetal growth. This cross-sectional study investigated the association between maternal micronutrient, fruit and vegetable intake with birth size. Nutrient and food intake were examined using a validated semi-quantitative food frequency questionnaire. One hundred twenty-one pregnant women at 28 to 38 weeks gestation aged 19-40 years, were recruited from the Universiti Sains Malaysia Hospital, Malaysia. Birth weight, length and head circumference were obtained from the medical records. Data were analyzed using multiple linear regression. Results indicate no significant association between any of the measured micronutrients and birth size. However, 2 of the 6 vegetable subgroups and those consumed fruit during pregnancy had children whose birth size was significantly associated with consumption. An increase of 10 g of leafy vegetables per day was associated with a 1.78 cm increase in head circumference (p = 0.04), and tuber vegetable intake was associated with birth length (beta = 0.21, p = 0.03) and head circumference (beta = 0.21, p = 0.01). Fruit intake was associated with birth weight (beta = 0.19, p = 0.04), birth length (beta = 0.20, p = 0.04) and head circumference (beta = 0.19, p = 0.03). The lack of association between maternal nutrient intake and fetal growth and the significant association between fruit and vegetable intake and birth size suggests the existence of other micronutrients and phytochemicals present in foods that play an important role in birth size. The types of nutrients and their roles in birth size warrant further investigation.

    Small head size has been observed in prenatally anticonvulsant-exposed neonates. In infancy, cognitive impairments were revealed. It is presently unknown whether these impairments are permanent or disappear after puberty. We studied the link between the prenatal influence of anticonvulsants on brain development and cognitive functioning in adulthood: a retrospective study on head size and a follow-up assessing cognitive capacities among adults who had been included in the retrospective study. The retrospective study comprised 172 exposed and 168 control neonates, matched with respect to age, sex and their mothers' age. Prenatally phenobarbital + phenytoin-exposed neonates had a significantly smaller occipitofrontal circumference (OFC) than prenatally phenobarbital-monotherapy-exposed and control neonates (mean difference of 0.7 cm). In the follow-up, no difference in cognitive functioning was found between the exposed and the control groups. Most of the prenatally anticonvulsant-exposed subjects had normal intellectual capacity. However, 12% of the exposed subjects versus 1% of the controls had persistent learning problems. In addition, more of the exposed subjects were mentally retarded. There was no clear relationship between learning problems and small OFC, maternal epilepsy or unfavourable family climate. We conclude that the combination of phenobarbital + phenytoin affects the fetal OFC. The smaller OFC does not seem to be related to cognitive functioning in adulthood, but learning problems and mental retardation proved to be more prevalent among exposed subjects. Phenobarbital and phenytoin may therefore affect cognitive capacity but only in infants who are susceptible to this particular influence of the drugs.

    The objective was to investigate the association of maternal weight, height and body composition with fetal growth. We recruited 425 women at the University Hospital of the West Indies, Jamaica, who had singleton pregnancies, were less than 15 weeks gestation and had no systemic illness. Maternal weight, height and skinfold thicknesses were measured at the first antenatal visit and lean mass was calculated. Sonographic measurements of the fetus were made at 15, 25 and 35 weeks gestation. Weight, crown-heel length and head circumference were measured at birth. Analyses were confined to 360 (85%) women; 65 women did not complete the study. Maternal height was positively associated with femoral length at 25 and 35 weeks gestation and with head circumference at 35 weeks (all P < 0.02). Maternal weight was positively associated with abdominal circumference and femoral length at 25 weeks, and with larger head and abdominal circumference and longer femur at 35 weeks (all P < 0.02). Maternal lean mass had similar associations to maternal weight and they were both positively associated with estimated fetal weight (all P < 0.02). All three maternal measurements were positively associated with birthweight, length and head circumference. Maternal size was associated with fetal size as early as 25 weeks gestation, with height strongly associated with femoral length, and with weight and lean mass strongly associated with abdominal circumference. © 2012 John Wiley & Sons Ltd.

    This study aimed to examine the potential association between maternal PBDEs and birth outcomes, including birth weight (g), length (cm), head circumference (cm) and gestational age (week). 215 mothers were recruited from a prospective birth cohort in rural northern China between September 2010 and February 2012. Serum PBDE congeners were detected and their association with birth outcomes were examined. The median maternal serum concentrations of BDE-28, -47, -99, -100, -153 were 2.27, 2.26, 3.58, 2.13, 4.87 ng/g lipid, respectively. Maternal LgBDE-28 and LgBDE-100 were negatively associated with birth length (β = −0.92, 95% confidence interval (CI): −1.82, −0.02; β = −0.97, 95% CI: −1.83, −0.08). A negative association was found between LgBDE-28 and birth weight among male infants (β = −253.76, 95% CI: −438.16, −69.36). PBDE congeners were not associated with head circumference, or gestational age. Our results contribute to growing evidence suggesting that PBDEs have adverse effects on birth outcomes. - Highlights: • We examined the relations between maternal exposure to PBDEs and birth outcomes. • BDE-28, -47, -99, -100, and -153 were detected in serum from 215 pregnant women. • There was a negative association between BDE-28, -100 and birth length. • BDE-28 showed a negative association with birth weight among male infants. - Negative associations were found between BDE-28, -100 exposure and birth length as well as between BDE-28 exposure and birth weight in male infants.

    This study aimed to evaluate the effects of maternal nutritional supplementation (MNS) in conjunction with a breastfeeding support program on birth outcomes and breastfeeding performance. A total of 228 singleton Vietnamese mothers aged 20-35 years at 26-29 weeks of gestation with pre-pregnancy body mass index (BMI) birth weight (p = .0312), birth weight-for-age (p = .0141) and birth head circumference-for-age (p = .0487), and higher head circumference-for-age z-score (p = .0183) development over the postnatal period, compared with the control. Use of MNS and breastfeeding support improve birth outcomes and exclusive breastfeeding (EBF) rate in Vietnamese mothers. Additionally, it promotes breast milk production among mothers with lower baseline MUAC.

    This cross-sectional study was carried out to capture possible maternal factors affecting newborns' anthropometric measurements. Data were collected from eight public health centres and referral university hospital records in Tabriz and Heriss districts, north-west Iran, for 807 mother-neonate pairs delivering live singleton births and their offspring during the two years up to August 2014. The incidence of low birth weight (LBW) was 5.1%. A close correlation was found between maternal anthropometry and birth order with neonatal anthropometric data. Birth order and maternal height and body mass index (BMI) positively affected neonates' birth size (weight, length and head circumference). The rate of LBW was significantly higher for older (≥35 years), taller (≥170 cm), underweight (BMIbirth neonates. The results indicate that maternal anthropometric indices, age, iron intake and birth order influence the risk of LBW in newborns.

    Corn Soya Blend (CSB) Plus is a fortified dietary supplement used to help Cambodian women meet their nutritional requirements in pregnancy, although little is known about its ability to improve pregnancy outcomes. This study assessed the effect of prenatal CSB Plus supplementation on birth weight and secondary outcomes of low birth weight (birth length and head circumference, preterm birth (birth weight between the CSB Plus and control group (46 g; 95% CI: -31, 123 g; P = 0.24). Significant reductions were observed in preterm birth (OR = 0.33; 95% CI: 0.12, 0.89) and anemia at 36-38 wk (OR = 0.51; 95% CI: 0.34, 0.77). There were no significant differences in low birth weight, small for gestational age, birth length, head circumference, or maternal weight gain. A higher rate of fetal loss was observed in the treatment group (10.2% compared with 3.7%; P birth size but did reduce maternal anemia in late gestation and preterm birth in comparison with women consuming a normal diet. The unexpectedly higher rate of fetal loss in the treatment group is concerning and warrants further investigation.

    Assistance during delivery by a skilled attendant is recommended as a means to reduce child and maternal mortality. Globally, higher levels of maternal education have been associated with better health behaviours at delivery. However, given that heads of households tend to be the decision makers regarding accessing healthcare, some educated mothers may find themselves prevented from accessing healthcare at the point of delivery. We examined the association between head of household education level and health seeking behaviours at delivery across a sample of 392 households. Chi-squared analysis and odds ratios were calculated to measure the strength of the relationship between no, some primary, or some secondary or higher education attained by the head of household and the presence or absence of a skilled birth attendant at that child's birth, and whether the birth took place at a health facility. Heads of household (n = 392) were predominantly male (93.4% [(90.9%, 95.8%), a = 0.05]). We found a significant difference in skilled birth attendance between heads of households with some primary education and heads of household with some secondary education or higher (χ2 (1) = 6.231, p birth attendant (OR = 1.5,[1.1,2.1]). The difference in health centre delivery between heads of household with a primary education and heads of household with a secondary or higher education was also significant (χ2 (1) = 7.519, p rates of health centre deliveries and utilization of services provided by skilled health workers might lie, in part, in increasing overall education levels of heads of households, specifically the education of male heads of households.

    We previously reported an association between prenatal exposure to airborne polycyclic aromatic hydrocarbons (PAH) and lower birth weight, birth length, and head circumference. The main goal of the present analysis was to assess the possible impact of coexposure to PAH-containing barbecued meat consumed during pregnancy on birth outcomes. The birth cohort consisted of 432 pregnant women who gave birth at term (>36 wk of gestation). Only non-smoking women with singleton pregnancies, 18-35 y of age, and who were free from chronic diseases such as diabetes and hypertension, were included in the study. Detailed information on diet over pregnancy was collected through interviews and the measurement of exposure to airborne PAHs was carried out by personal air monitoring during the second trimester of pregnancy. The effect of barbecued meat consumption on birth outcomes (birth weight, length, and head circumference at birth) was adjusted in multiple linear regression models for potential confounding factors such as prenatal exposure to airborne PAHs, child's sex, gestational age, parity, size of mother (maternal prepregnancy weight, weight gain in pregnancy), and prenatal environmental tobacco smoke. The multivariable regression model showed a significant deficit in birth weight associated with barbecued meat consumption in pregnancy (coeff = -106.0 g; 95%CI: -293.3, -35.8). The effect of exposure to airborne PAHs was about the same magnitude order (coeff. = -164.6 g; 95%CI: -172.3, -34.7). Combined effect of both sources of exposure amounted to birth weight deficit of 214.3 g (95%CI: -419.0, -9.6). Regression models performed for birth length and head circumference showed similar trends but the estimated effects were of borderline significance level. As the intake of barbecued meat did not affect the duration of pregnancy, the reduced birth weight could not have been mediated by a shortened gestation period. In conclusion, the study results provided epidemiologic

    To determine the predictive ability of acculturation as an antecedent of stress, biobehavioral risk, corticotropin-releasing hormone levels, and poor birth outcomes in pregnant Hispanic women. A prospective, observational design with data collected at 22-25 weeks of gestation and at birth through medical record review. Public prenatal health clinics in south Texas serving low-income women. Self-identified Hispanic women who had singleton pregnancies, no major medical risk complications, and consented to answer questionnaires as well as a venipuncture and review of their prenatal and birth medical records. Gestational age, Apgar scores, length, weight, percentile size, and head circumference of the infant at birth. Significant differences were seen in infant birth weight, head circumference, and percentile size by acculturation. English acculturation predicted stress, corticotropin-releasing hormone, biobehavioral risk, and decreased gestational age at birth. Investigation must continue to understand the circumstances that give rise to the decline in birth outcomes observed in Hispanics with acculturation to the dominant English culture in the United States.

    The aim of the study was to determine whether nutritional status of pregnant women influences the birth outcome. A prospective study, conducted in Krakow, in 382 non-smoking, no obese pregnant women between the ages of 18 - 35. The course of pregnancy was uncomplicated, finished with natural labor, in biological time limits. The impact of mother's nutritional status before pregnancy and weight gain on newborns weight, length and head circumference was estimated by multivariate linear regression. The infant birth weight depended on mothers nutritional status before pregnancy and was lower in the group of underweight subjects (3381.6 g vs. 3479.9 g, p = 0.022). Women with low increase in body mass during pregnancy delivered newborns with lower anthropometrics parameters. The increase in body weight of one category resulted in statistically significant increase of birth weight by 140.9 g, increase of length by 0.51 cm and in head circumference by 0.27 cm. Increase in body mass during pregnancy is particularly important in the group of women underweight before pregnancy. Change of nutritional habits before and in the course of pregnancy may have beneficial effects for intrauterine fetal development.

    We evaluate the relative importance of birth weight and postnatal growth for cognition and behavioural development in 8389 Chinese children, 4-7 years of age. Method Weight was the only size measure available at birth. Weight, height, head circumference and intelligence quotient (IQ) were measured between 4 and 7 years of age. Z-scores of birth weight and postnatal conditional weight gain to 4-7 years, as well as height and head circumference at 4-7 years of age, were the exposure variables. Z-scores of weight at 4-7 years were regressed on birth weight Z-scores, and the residual was used as the measure of postnatal conditional weight gain. The outcomes were child's IQ, measured by the Chinese Wechsler Young Children Scale of Intelligence, as well as internalizing behavioural problems, externalizing behavioural problems and other behavioural problems, evaluated by the Child Behavior Checklist 4-18. Multivariate regressions were conducted to investigate the relationship of birth weight and postnatal growth variables with the outcomes, separately for preterm children and term children. Both birth weight and postnatal weight gain were associated with IQ among term children; 1 unit increment in Z-score of birth weight (∼450 g) was associated with an increase of 1.60 [Confidence interval (CI): 1.18-2.02; P < 0.001] points in IQ, and 1 unit increment in conditional postnatal weight was associated with an increase of 0.46 (CI: 0.06-0.86; P = 0.02) points in IQ, after adjustment for confounders; similar patterns were observed when Z-scores of postnatal height and head circumference at age 4-7 years were used as alternative measurements of postnatal growth. Effect sizes of relationships with IQ were smaller than 0.1 of a standard deviation in all cases. Neither birth weight nor postnatal growth indicators were associated with behavioural outcomes among term children. In preterm children, neither birth weight nor postnatal growth measures were associated with IQ or

    Although pregnancy concentrations of some phenols have been associated with infant size at birth, there is limited data on the effect of preconception exposure. We aimed to examine paternal and maternal preconception and maternal prenatal urinary phenol concentrations in relation to birth weight and head circumference. We evaluated 346 singletons born to 346 mothers and 184 fathers (184 couples) from a prospective preconception cohort of subfertile couples from the Environment and Reproductive Health (EARTH) Study in Boston, USA. We used multiple urine samples collected before the index pregnancy in both men and women to estimate mean preconception urinary benzophenone-3, triclosan, butylparaben, propylparaben, methylparaben, or ethylparaben concentrations. We also estimated mean maternal prenatal urinary phenol concentrations by averaging trimester-specific urine samples. Birth weight and head circumference were abstracted from delivery records. We estimated the association of natural log-phenol concentrations with birth outcomes using multivariable linear regression models, adjusting for known confounders. In adjusted models, each log-unit increase in paternal preconception benzophenone-3 concentration was associated with a 137 g increase in birth weight (95% CI: 60, 214). Additional adjustment for prenatal benzophenone-3 concentration strengthened this association. None of the maternal preconception phenol concentrations were associated with birth weight. However, maternal prenatal triclosan concentrations were associated with a 38 g decrease in birth weight (95% CI: -76, 0). Few associations were observed between phenols and head circumference except for a decrease of 0.27 cm (95% CI: -54, 0) in relation to maternal preconception methylparaben concentration. Although our findings should be interpreted in light of inherent study limitations, these results suggest potential evidence of associations between some paternal or maternal phenol concentrations and

    Full Text Available Objective: This study was conducted aimed to compare the growth indices in 2 years old children with a history of low birth weight with normal birth weight children.Methods: Current retrospective cohort study on all two-year children with low birth weight and three times the normal weight children covered by health centers of Kahnooj, was conducted in 2015. Cares at birth, 1, 2, 4, 6, 7, 9, 12, 15, 18 and 24 months of age were studied and, child growth indices (weight, height, head circumference, along with some demographic variables were studied. Information were entered SPSS version 20 and the analysis was performed.Results: There were significant differences in children's growth of both groups in all periods of care. Despite the same slope, growth pattern in children showed a significant difference. Young mother, girl sex of baby and preterm birth are predictor factors of low birth weight.Conclusion: Trends and growth patterns of weight, height and head circumference in underweight children have significant difference with normal children and, despite the same slope, these children can not compensate for the backwardness of its growth to the age of two. So you need to plot separate growth curves for these children and, possible preventive measures should be taken to prevent bearing underweight baby.

    This study aimed to: (1) examine the role of multiple measures of prepregnancy nutritional status (weight, height, body composition) on birth outcomes (low birth weight (LBW), small for gestational age (SGA), preterm, birth weight, birth length, infant head circumference and mid-upper arm circumference (MUAC)); (2) assess relative influence of maternal nutritional status before and during (gestational weight gain) pregnancy on birth outcomes. We used prospective data on maternal body size and composition collected from women who participated in a randomized controlled trial evaluating the impact of preconceptional micronutrient supplements (PRECONCEPT) on birth outcomes in Thai Nguyen province, Vietnam (n=1436). Anthropometric measurements were obtained before conception through delivery by trained health workers. The relationship between prepregnancy nutritional status indicators, gestational weight gain (GWG) and birth outcomes were examined using generalized linear models, adjusting for potential confounding factors. Maternal prepregnancy weight (PPW) was the strongest anthropometric indicator predicting infant birth size. A 1 standard deviation (SD) increase in PPW (5.4kg) was associated with a 283g (95%CI: 279-286) increase in birthweight. A similar and independent association was observed with birthweight for an increase of 1 SD in gestational weight gain (4kg) (250g; 95% CI: 245-255). Women with a PPW maternal nutrition both before and during pregnancy. Women with a PPW <43kg or a GWG <8kg are at greatest risk for poor birth outcomes in this setting. Preconception counseling and clinical care to obtain a healthy weight prior to pregnancy along with routine obstetric care on gestational weight gain is critical to improve birth outcomes.

    The aim of the present study is to evaluate the effect of human milk feeding during the first weeks of life in very low birth weight infants on weight gain at discharge, length of hospitalization, postmenstrual age at discharge and nutritional assessment, growth and neurodevelopment at two and five years. Longitudinal study of very-low-birth-weight infants (Care Unit of La Paz University Hospital, from January 1st 2009 to December 31st 2009, followed in the follow-up clinic. Their parents agreed to perform a more exhaustive anthropometric study at five years, classified according to the type of feeding at the time of discharge (exclusive human milk, formula milk or mixed). Initial hospital duration and anthropometry at discharge were evaluated. At two years of age, anthropometric data (weight, height and head circumference) were collected and neurodevelopment was assessed according to the Bayley scale of child development. Data at five years were collected prospectively. Measurements of weight, height and head circumference, waist circumference, hip, relaxed and contracted arm, thigh and middle leg, bicipital, triceps, subscapular, suprailiac and leg skin folds were performed. For patients older than five years, the Kaufman test battery for children was used. The effect of human milk on the variables of interest was investigated using a multivariate analysis correcting for gestational age and weight at birth. One hundred and fifty-two infants born in 2009 were discharged from our unit: exclusive breast milk (59), formula (55) or mixed milk (38). More detailed follow-up was carried out for 61 of them. Human milk during the first admission decreases the initial hospital stay, and is associated with a higher head circumference at two and five years, and a better score in the global and verbal cognitive area at five years. Our results suggest that maternal milk feeding during initial admission should be encouraged because it can improve neurodevelopment at five years

    This study was to investigate whether exposure to cadmium (Cd) during pregnancy is associated with an increased risk of adverse birth outcomes in a sex-dependent manner. Cd concentrations in maternal urine (U-Cd) samples were measured in 237 subjects from Guiyu (e-waste area) and 212 subjects from Haojiang. A significance level of p <0.05 was used for all analyses. The maternal U-Cd levels in Guiyu residents were significantly higher than Haojiang. We found significant inverse associations between U-Cd concentrations and birth anthropometry (birth weight, birth length, Head Circumference and Apgar scores with 1min and 5 mins) in female neonates, but no significant associations were observed in male neonates except Apgar (1min) score after adjustment. The association was more pronounced among female neonates than male neonates, suggesting an association between Cd and adverse birth outcomes may be sex-specific. Copyright © 2017 Elsevier Inc.

When PFOS levels were divided into quartiles, a dose-response relation was observed. However, PFOA, PFNA, and PFUA were not observed to have any convincing impact on birth outcomes.An adverse dose-dependent association was observed between prenatal PFOS exposure and birth outcomes. However, no associations were found for the other examined PFCs.

This cross-sectional study was conducted in 1800 school-going adolescents. Body mass index, waist circumference and neck circumference were measured. Independent samples t-test and Pearson's correlation were used as tests of significance to analyze quantitative data. Positive correlation of neck circumference and waist circumference with body mass index was observed. The neck circumference and waist circumference in overweight/obese adolescents were significantly higher than adolescents with normal body mass index (Padolescent obesity in boys and girls were 30.75 cm, and 29.75 cm, respectively, and waist circumference cut-off value were 70.75 cm for boys and 69.25 cm for girls at fairly good levels of sensitivity and specificity. Neck circumference and waist circumference may be used in clinical practice and epidemiological studies as an index of overweight/ obesity among school-going adolescents.

Calibration for these discrepancies resulted in a lower post-term birth rate, from 3.1-1.4%, when first compared to second trimester dating was used. CONCLUSIONS: Systematic discrepancies were identified when biometric formulas were used to determine duration...

    Compared with other primates, childbirth is remarkably difficult in humans because the head of a human neonate is large relative to the birth-relevant dimensions of the maternal pelvis. It seems puzzling that females have not evolved wider pelvises despite the high maternal mortality and morbidity risk connected to childbirth. Despite this seeming lack of change in average pelvic morphology, we show that humans have evolved a complex link between pelvis shape, stature, and head circumference that was not recognized before. The identified covariance patterns contribute to ameliorate the "obstetric dilemma." Females with a large head, who are likely to give birth to neonates with a large head, possess birth canals that are shaped to better accommodate large-headed neonates. Short females with an increased risk of cephalopelvic mismatch possess a rounder inlet, which is beneficial for obstetrics. We suggest that these covariances have evolved by the strong correlational selection resulting from childbirth. Although males are not subject to obstetric selection, they also show part of these association patterns, indicating a genetic-developmental origin of integration.

    Exposure to 4-tert-octylphenol (tOP) has been linked with adverse health outcomes in animals and humans, while epidemiological studies about associations between prenatal exposure to tOP and fetal growth are extremely limited. We measured urinary tOP concentrations in 1100 pregnant women before their delivery, and examined whether tOP levels were associated with birth outcomes, including weight, length, head circumference and ponderal index at birth. tOP could be detected in all samples, and the median uncorrected and creatinine-corrected tOP concentrations were 0.90 μg/L (range from 0.25 to 20.05 μg/L) and 1.33 μg/g creatinine (range from 0.15 to 42.49 μg/g creatinine), respectively. Maternal urinary log-transformed tOP concentrations were significantly negatively associated with adjusted birth weight [β (g) = −126; 95% confidence interval (CI): −197, −55], birth length [β (cm) = −0.53; 95% CI:−0.93, −0.14], and head circumference [β (cm) = −0.30; 95% CI: −0.54, −0.07], respectively. Additionally, considering sex difference, these significant negative associations were also found among male neonates, while only higher maternal tOP concentrations were associated with a significant decrease in birth weight among female neonates. This study suggested significant negative associations between maternal urinary tOP concentrations and neonatal sizes at birth, and they differed by neonatal sex. Further epidemiological studies are required to more fully elaborate the associations between prenatal tOP exposure and birth outcomes. - Highlights: • We measured 4-tert-octylphenol (tOP) in urine from 1100 Chinese pregnant women. • The associations between maternal tOP levels and birth outcomes were investigated. • Prenatal exposure to tOP in the selected area was widespread at higher levels. • Maternal tOP levels were significantly negatively associated with birth sizes. • The associations between tOP and birth outcomes might

    The aim of our study was to assess associations between smoking behavior before and during pregnancy and selected adverse birth outcomes. This study is based on the Murmansk County Birth Registry (MCBR). Our study includes women who delivered a singleton pregnancy after 37 weeks of gestation (N = 44,486). Smoking information was self-reported and assessed at the first antenatal visit during pregnancy. We adjusted for potential confounders using logistic regression. The highest proportion of infants with low values of birth weight, birth length, head circumference, ponderal index and of the Apgar score at 5 min was observed for women who smoked both before and during pregnancy. We observed a dose-response relationship between the number of cigarettes smoked per day during pregnancy and the odds of the aforementioned adverse birth outcomes; neither were there significant differences in their occurrences among non-smokers and those who smoked before but not during pregnancy. Moreover, smoking reduction during pregnancy relative to its pre-gestation level did not influence the odds of the adverse birth outcomes. Our findings emphasize a continued need for action against tobacco smoking during pregnancy.

  18. Association of organophosphate pesticide exposure and paraoxonase with birth outcome in Mexican-American women.

    Directory of Open Access Journals (Sweden)

    Kim G Harley

    Full Text Available Epidemiologic studies suggest that maternal organophosphorus (OP pesticide exposure is associated with poorer fetal growth, but findings are inconsistent. We explored whether paraoxonase (PON1, a key enzyme involved in detoxification of OPs, could be an effect modifier in this association.The study population included 470 pregnant women enrolled in the CHAMACOS Study, a longitudinal cohort study of mothers and children living in an agricultural region of California. We analyzed urine samples collected from mothers twice during pregnancy for dialkyl phosphate (DAP metabolites of OP pesticides. We analyzed maternal and fetal (cord blood samples for PON1 genotype (PON1(192 and PON1(-108 and enzyme activity (paraoxonase and arylesterase. Infant birth weight, head circumference, and gestational age were obtained from medical records.Infants' PON1 genotype and activity were associated with birth outcome, but mothers' were not. Infants with the susceptible PON1(-108TT genotype had shorter gestational age (β = -0.5 weeks, 95% Confidence Interval (CI: -0.9, 0.0 and smaller head circumference (β = -0.4 cm, 95% CI: -0.7, 0.0 than those with the PON1(-108CC genotype. Infants' arylesterase and paraoxonase activity were positively associated with gestational age. There was some evidence of effect modification with DAPs: maternal DAP concentrations were associated with shorter gestational age only among infants of the susceptible PON1(-108TT genotype (p-value(interaction = 0.09. However, maternal DAP concentrations were associated with larger birth weight (p-value(interaction = 0.06 and head circumference (p-value(interaction<0.01 in infants with non-susceptible genotypes.Infants whose PON1 genotype and enzyme activity levels suggested that they might be more susceptible to the effects of OP pesticide exposure had decreased fetal growth and length of gestation. PON1 may be another factor contributing to preterm or low birth weight birth.

    Many pregnant women take vitamin supplements during pregnancy. The aim of this paper was to clarify the effects of dietary supplementation prior to and/or during pregnancy on child behavior. A prospective birth cohort study from pregnancy to 3 years of age involving 1271 pairs of Japanese pregnant women and their newborns, was carried out. The women completed a self-administered questionnaire during the third trimester of pregnancy. To evaluate deviations in child behavior as an endpoint, each mother completed the Japanese Child Behavior Checklist for ages 2-3 years after 3 years of birth. Participant characteristics were compared between supplement takers and non-takers. Among many kinds of supplements, intake of supplemental vitamin A/β-carotene prior to and/or during pregnancy was associated with hazardous effects on child behavior at 3 years of age (total t-score, P = 0.003; internal t-score, P = 0.027; external t-score, P = 0.013). This association held true even after adjusting for age, number of deliveries, infertility treatment, consumption of fast food, smoking status, maternal and paternal education, maternal and paternal income, gestational age at birth, anthropometry at birth (weight, height, head circumference and body circumference), and the State-Trait Anxiety Inventory at 3 years of age by means of multiple imputation. Intake of supplemental vitamin A prior to and/or during pregnancy may worsen child behavior at 3 years of age. © 2016 Japan Pediatric Society.

    We sought to assess the association between prenatal head growth and child neuropsychological development in the general population. We evaluated 2104 children at the age of 14 months from a population-based birth cohort in Spain. Head circumference (HC) was measured by ultrasound examinations at weeks 12, 20, and 34 of gestation and by a nurse at birth. Head growth was assessed using conditional SD scores between weeks 12-20 and 20-34. Trained psychologists assessed neuropsychological functioning using the Bayley Scales of Infant Development. Head size measurements at birth were transformed into a 3-category variable: microcephalic (psychomotor scores. In particular, no associations were found between HC at birth and mental scores (coefficient, 0.04; 95% confidence interval, -0.02 to 0.09) and between interval head growth (20-34 weeks) and mental scores (0.31; 95% confidence interval, -0.36 to 0.99). Upon stratification by microcephalic, normocephalic, or macrocephalic head size, results were imprecise, although there were some significant associations in the microcephalic and macrocephalic groups. Adjustment by various child and maternal cofactors did not affect results. The minimum sample size required for present study was 883 patients (β=2, α=0.05, power=0.80). Overall prenatal and perinatal HC was not associated with 14-month-old neuropsychological development. Findings suggest HC growth during uterine life among healthy infants may not be an important marker of early-life neurodevelopment but may be marginally useful with specific populations.

    Nutritional deficits are almost universal in Low-Birth Weight babies. Zinc is essential for normal infant growth and its supplementation assists growth probably through insulin-like growth factor-1. This double-blind randomized-controlled trial aimed at evaluating the role of zinc in catch-up growth of low-birth-weight infants and investigating its proposed mediator. The study was conducted in Ain Shams University Maternity Hospital. Two hundred low-birth-weight neonates were simply randomized to either oral zinc therapy or placebo. Anthropometric measurements were recorded at birth, 3, 6, and 12 months; including weight, recumbent length, head, waist, chest, and mid-upper arm circumferences, and triceps and sub-scapular skin fold thickness. We found that initial and 3-months measurements, except weight, were comparable in the 2 groups. All measurements at 6- and 12-months, except sub-scapular skin-fold-thickness, were significantly higher in zinc group than placebo. Catch-up growth, at 12-months, was significant in zinc group and was significantly higher in appropriate-for-gestational-age vs. small-for-gestational-age, in preterm vs. term, and in male vs. female infants. The median 6-months insulin-like growth factor-1 levels were significantly higher in zinc group. We conclude that early start of oral zinc supplementation in low-birth-weight neonates assists catch-up growth, probably through rise of insulin-like growth factor-1.

    We analyzed the impact of birth parameters and parental height on long-term growth outcome in children with chronic kidney disease (CKD) stage 3-5. Linear growth was prospectively investigated in 509 children, with a mean follow-up of 4.1 years. Growth outcome was categorized in (i) poor growth (PG): height standard deviation score (SDS) during follow-up growth hormone (GH) treatment, and (ii) good growth (GG): height SDS ≥ -2.0 and no need for GH. A multivariate binary logistic regression model was constructed for predictors of PG outcome. PG was observed in 55 % of patients. The rate of pre-term and small for gestational age birth was significantly higher in children with PG compared to GG (43.2 vs. 25.6 % and 36.8 vs. 18.9 %; p Children with PG had significantly lower average values for gestational age, birth weight, length, and head circumference, umbilical cord pH, Apgar scores, and parental height than children with GG. Birth length, umbilical cord pH, and parental height were significant independent predictors of PG outcome (sensitivity 72.8 %, specificity 69.3 %). Birth parameters and parental height are independent predictors of growth outcome in children with CKD.

    Increasing evidence suggests an inverse association between cadmium (Cd) and size at birth, potentially greatest among female neonates. We evaluated whether greater maternal body burden of Cd is associated with reduced neonatal anthropometry (birthweight, birth length, head circumference, and ponderal index) and assessed whether these associations differ by infant sex. The analytic sample for the present study (n=396) was derived from a subcohort of 750 women randomly drawn from among all participants (N=4344) in the Omega Study, a prospective pregnancy cohort. Creatinine-corrected Cd in maternal clean-catch spot urine samples (U-Cd) was quantified by inductively coupled plasma mass spectrometry. Continuous log 2 -transformed Cd (log 2 -Cd) and U-Cd tertiles (low<0.29 μg/g creatinine, middle 0.29–0.42 μg/g creatinine, high≥0.43 μg/g creatinine) were used in multivariable linear regression models. Females had reduced birth length with greater U-Cd tertile, whereas males birth length marginally increased [β(95% CI) females: low=reference, middle=−0.59 cm (−1.37, 0.19), high=−0.83 cm (−1.69, 0.02), p-trend=0.08; males: low=reference, middle=0.18 cm (−0.59, 0.95), high=0.78 cm (–0.04, 1.60), p-trend=0.07; p for interaction=0.03]. The log 2 -Cd by infant sex interaction was statistically significant for ponderal index [p=0.003; β(95% CI): female=0.25 kg/m 3 (−0.20, 0.70); male=−0.63 kg/m 3 (−1.01, −0.24)] and birth length [p<0.001; β(95% CI): female=−0.47 cm (−0.74, −0.20), male=0.32 cm (0.00, 0.65)]. Our findings suggest potential sex-specific reversal of Cd’s associations on birth length and contribute to the evidence suggesting Cd impairs fetal growth. - Highlights: • Cadmium levels in the general population potentially adversely affect size at birth. • Maternal urinary cadmium was inversely related to birth length among female infants. • For male infants, maternal cadmium was positively associated with birth length.

    Full Text Available This analysis was conducted to explore the association between 5 birth size measurements (weight, length and head, chest and mid-upper arm [MUAC] circumferences as dependent variables and 10 maternal factors as independent variables using canonical correlation analysis (CCA. CCA considers simultaneously sets of dependent and independent variables and, thus, generates a substantially reduced type 1 error. Data were from women delivering a singleton live birth (n = 14,506 while participating in a double-masked, cluster-randomized, placebo-controlled maternal vitamin A or β-carotene supplementation trial in rural Bangladesh. The first canonical correlation was 0.42 (P<0.001, demonstrating a moderate positive correlation mainly between the 5 birth size measurements and 5 maternal factors (preterm delivery, early pregnancy MUAC, infant sex, age and parity. A significant interaction between infant sex and preterm delivery on birth size was also revealed from the score plot. Thirteen percent of birth size variability was explained by the composite score of the maternal factors (Redundancy, RY/X = 0.131. Given an ability to accommodate numerous relationships and reduce complexities of multiple comparisons, CCA identified the 5 maternal variables able to predict birth size in this rural Bangladesh setting. CCA may offer an efficient, practical and inclusive approach to assessing the association between two sets of variables, addressing the innate complexity of interactions.

    Previous research has suggested that abdominal obesity and mental disorders are associated. This paper was initiated to investigate associations between unfavourable waist circumference (WC) and mental disorders in a representative sample of German adults. 4181 individuals (aged 18-65 years) took part in a physical examination (including measurement of body weight and WC) and a structured psychological interview (M-CIDI) to evaluate mental disorders. An unfavourable WC (males: 26.9%; females: 31.3%) was highly prevalent. However, unfavourable WC and mental disorders were not associated, neither with regard to the prevalence of any mental disorder nor regarding in particular depressive disorders. Moreover, even middle-aged depressive women that have often been assumed to be at high risk of increased visceral fat did not show more unfavourable WCs than their non-depressed, female counterparts. The main limitation is that the co-occurrence of mental disorders and obesity was recorded but not, if obesity was related to the onset of mental problems. From an epidemiologic perspective, it is not possible to prove associations between WC and mental disorders. Patients with unfavourable waist circumferences do not show a higher prevalence of depressive disorders.

    Introduction Identifying newborns who weight 4000 g or more is important because birth of macrosomic fetuses is associated with adverse peripartum outcomes. Ultrasound is widely used for this purpose Our objective was to evaluate the diagnostic value of sonographic measurement of fetal abdominal circumference (AC) over 350 mm for the prediction of fetal macrosomia and shoulder dystocia, to specify factors that could generate errors in its measure. Methods A retrospective clinical trial was conducted at the Department of Obstetrics and Gynecology, Hédi Chaker Hospital, Sfax, Tunisia. The study consisted of comparing two groups of singleton newborns: the first group (n=465) includes macrosomic babies and the second group (n=465) includes the non macrosomic ones. All women underwent sonographic measurements of the fetal abdominal circumference (AC) within 72 hours before delivery. The AC values were correlated to actual fetal birth weight. The cut-off value of AC for predicting of fetal macrosomia was analyzed. Results A cut-off value of abdominal circumference ≥350 mm, in predicting of fetal macrosomia., had a sensitivity, specificity, accuracy, positive predictive value, and negative predictive value: 78.7%, 76.8%, 77%, 92.6%, and 49.2%, respectively. In macrosomic group obesity was significantly more frequent when AC≥350mm. Conclusion The fetal AC measurement was useful in predicting of fetal macrosomia. An AC measurement AC≥350mm could help to suspect shoulder dystocia. PMID:23717725

    The contribution of growth parameters to the cognitive outcome of very low birth weight (VLBW)/very preterm (VP) infants is difficult to disentangle from other preterm-birth related factors. We hypothesized that long-term cognitive and motor outcome of VLBW/VP infants is most strongly associated with growth in head circumference after hospital discharge. Single-centre prospective longitudinal study: anthropometric measures at different time points (birth, discharge, school-age). 136 VLBW/VP infants (Children; Movement Assessment Battery for Children) at school-age (6.7-10.0years, mean=8.2). In hierarchical multiple regression analyses, growth from birth to discharge significantly predicted cognitive outcome (weight: R 2 change =0.063, p=0.014; length: R 2 change =0.078, p=0.007; HC: R 2 change =0.050, p=0.030), as well as weight gain (R 2 change =0.096, p=0.001) and head growth (R 2 change =0.134, pgrowth parameters, especially those from birth to discharge, were significantly influenced by prenatal growth and immaturity related morbidity (R 2 =0.151 to 0.605, all p≤0.001), head growth after discharge was not (R 2 =0.029, p=0.461). Amongst all anthropometric measures, head growth between discharge and school-age is the best independent predictor for cognitive outcome in VLBW/VP infants. Determinants of head growth after discharge need further studies to identify targets for intervention. Copyright © 2016. Published by Elsevier Ireland Ltd.

    Occupational psychosocial stress has been identified as a risk factor for obesity, whereas dietary habits have a key role in weight control. We examined whether dietary habits modify the association between occupational psychosocial factors and waist circumference. Data comprised 31-year-old men (n=2222) and women (n=2053) in the Northern Finland Birth Cohort 1966. Waist circumference was measured and data on occupational psychosocial factors (demands, control and social support) and other characteristics were obtained through questionnaires. Healthy and unhealthy diet indices were constructed according to the current dietary guidelines. Associations were examined using analysis of variance adjusted for body mass index at age 14, basic education level, leisure-time physical activity, alcohol consumption, smoking, stress-related eating behaviour and parity. Among men, high job demands and high job control were associated with greater waist circumferences, and there were interactions between unhealthy diet and job demands (P=0.043) and job control (P=0.036) in relation to waist circumference. The waist of men with high demands or high control and low consumption of unhealthy foods (red/processed meat, hamburgers and pizzas, fried potatoes, sugar-sweetened soft drinks and white bread) was smaller than that of men with high demands or high control and high consumption of such foods. No associations were found among women. A diet based on the current dietary guidelines seems to cancel out the adverse effects of occupational psychosocial factors on waist circumference among young men. Longitudinal studies are needed to assess the risks for obesity-related diseases arising from psychosocial work environments and dietary habits.

    Micronutrient deficiencies may be related to poor fetal growth and short gestation. Few studies have investigated the contribution of maternal vitamin A deficiency to these outcomes. In rural northwestern Bangladesh, we examined the effects of weekly antenatal vitamin A and β-carotene supplementation on birth weight, length, circumferential body measures, and length of gestation. With the use of a cluster-randomized, placebo-controlled trial design, pregnant women were enrolled in the first trimester and began receiving their allocated supplements (vitamin A, β-carotene, or placebo) weekly until 3 mo postpartum. Birth anthropometric measures were made at home. Of 13,709 newborns whose birth weight was measured within 72 h of birth, mean (±SD) weight was 2.44 ± 0.42 kg, the prevalence of low birth weight (LBW) was 54.4%, and that of small-for-gestational age (SGA) was 70.5%. Birth weight, length, and chest, head, and arm circumferences did not differ between supplementation and placebo groups nor did rates of LBW and SGA. Mean gestational age at birth was 38.3 ± 2.9 wk, and 25.6% of births occurred before 37 wk. Neither gestational age nor preterm birth rate differed with vitamin A or β-carotene supplementation. In this rural South Asian population with a high burden of LBW and preterm birth but modest levels of maternal vitamin A deficiency, antenatal vitamin A or β-carotene supplementation did not benefit these birth outcomes. Other nutritional and nonnutritional interventions should be examined to reduce risks of these adverse outcomes in rural South Asia. This trial was registered at clinicaltrials.gov as NCT00198822.

    Introduction: Maternal HIV infection and related co-morbidities may have two outstanding consequences to fetal health: mother-to-child transmission (MTCT) and adverse perinatal outcomes. After Brazilian success in reducing MTCT, the attention must now be diverted to the potentially increased risk for preterm birth (PTB) and intrauterine fetal growth restriction (IUGR). Objective: To determine the prevalence of PTB and IUGR in low income, antiretroviral users, publicly assisted, HIV-infected women and to verify its relation to the HIV infection stage. Patients and Methods: Out of 250 deliveries from HIV-infected mothers that delivered at a tertiary public university hospital in the city of Vitória, state of Espírito Santo, Southeastern Brazil, from November 2001 to May 2012, 74 single pregnancies were selected for study, with ultrasound validated gestational age (GA) and data on birth dimensions: fetal weight (FW), birth length (BL), head and abdominal circumferences (HC, AC). The data were extracted from clinical and pathological records, and the outcomes summarized as proportions of preterm birth (PTB, fetal dimensions than the expected population distribution in this small casuistry of newborn from the HIV-infected, low income, antiretroviral users, and publicly assisted pregnant women. A trend for higher prevalence of PTB, LBW and SGA fetal dimensions was also observed in infants born to mothers with AIDS compared to HIV-infected mothers without AIDS. PMID:25923889

    During midlife years, women are at risk of increasing body weight and waist circumference. We evaluated changes in weight and waist circumference from enrollment to 2 years later and examined the influence of physical activity level on those changes among 232 women aged between 40 and 50. Weight increased significantly for the entire sample. Those who increased their physical activity from enrollment to 2 years later had the smallest increase in weight and had a slight decrease in waist circumference. To maintain ideal weight and waist circumference, midlife women should be encouraged to increase physical activity before and during the menopausal transition.

    We aimed to examine detailed neonatal measurements as predictors of later diabetes in both parents. Babies (n = 617) born to nondiabetic parents in Holdsworth Memorial Hospital, Mysore, India, were measured at birth for weight; crown-to-heel length (CHL), crown-to-rump length (CRL), and leg length; skinfolds (triceps and subscapular); and circumferences (head, abdomen, and mid-upper-arm circumference [MUAC]). Nine and a half years later, glucose tolerance and fasting insulin were measured in their parents (469 mothers and 398 fathers). Sixty-two (15.6%) fathers and 22 (4.7%) mothers had developed diabetes. There were linear inverse associations of the children's birth weight, CHL, CRL, MUAC, and skinfolds with paternal diabetes and insulin resistance (P < 0.05 for all). Offspring birth weight and adiposity (MUAC, abdominal circumference, and skinfolds) showed U-shaped associations with maternal diabetes (P for quadratic association <0.05 for all). These associations persisted after adjusting for the parents' current adiposity and maternal glucose concentrations and adiposity during pregnancy. Newborn adiposity was positively related to maternal insulin resistance; this association was nonsignificant after adjusting for maternal current adiposity. Newborn size is a window into the future health of the parents. Small newborn size (especially soft-tissue body components) predicts an increased risk of later diabetes in both parents, suggesting a genetic or epigenetic link between parents' diabetes risk and reduced fetal growth in their children. The association of higher birth weight and newborn adiposity with later maternal diabetes suggests effects on fetal adiposity of the intrauterine environment in prediabetic mothers.

  1. Maternal prepregnancy waist circumference and BMI in relation to gestational weight gain and breastfeeding behavior

    DEFF Research Database (Denmark)

    Kirkegaard, Helene; Nohr, Ellen A; Rasmussen, Kathleen M

    2015-01-01

    BACKGROUND: Studies suggest that gestational weight gain (GWG) and breastfeeding behavior may influence long-term maternal abdominal fat mass. However, this could be confounded by abdominal fat mass before pregnancy because it is unknown whether abdominal fat mass, independently of body size......, affects GWG and breastfeeding behavior. OBJECTIVE: We investigated how maternal prepregnancy fat distribution, described by waist circumference (WC) and body mass index (BMI), is associated with GWG and breastfeeding behavior. DESIGN: We analyzed 1371 live births to 1024 women after enrollment...... in the Coronary Artery Risk Development in Young Adults study (1985-1996). For each birth, maternal prepregnancy BMI and WC were measured at year 0 (baseline), 2, 5, or 7 examinations. Recalled GWG and breastfeeding behavior were collected at years 7 and 10.

    Studies of the relationship between serum 25-hydroxyvitamin D (25(OH)D) and changes in measures of adiposity have shown inconsistent results, and interaction with genetic predisposition to obesity has rarely been examined. We examined whether 25(OH)D was associated with subsequent annual changes...... in body weight (ΔBW) or waist circumference (ΔWC), and whether the associations were modified by genetic predisposition to a high BMI, WC or waist-hip ratio adjusted for BMI (WHRBMI). The study was based on 10,898 individuals from the Danish Inter99, the 1958 British Birth Cohort and the Northern Finland...... Birth Cohort 1966. We combined 42 adiposity-associated Single Nucleotide Polymorphisms (SNPs) into four scores indicating genetic predisposition to BMI, WC and WHRBMI, or all three traits combined.

    Full Text Available Background: Prenatal and peripartum trauma may be associated with poor maternal–fetal outcomes. However, relatively few data on these associations exist from low-middle income countries, and populations in transition. Objective: We investigated the prevalence and risk factors for maternal trauma and posttraumatic stress disorder (PTSD, and their association with adverse birth outcomes in the Drakenstein Child Health Study, a South African birth cohort study. Methods: Pregnant women were recruited from two clinics in a peri-urban community outside Cape Town. Trauma exposure and PTSD were assessed using diagnostic interviews; validated self-report questionnaires measured other psychosocial characteristics. Gestational age at delivery was calculated and birth outcomes were assessed by trained staff. Multiple logistic regression explored risk factors for trauma and PTSD; associations with birth outcomes were investigated using linear regression. Potential confounders included study site, socioeconomic status (SES, and depression. Results: A total of 544 mother–infant dyads were included. Lifetime trauma was reported in approximately two-thirds of mothers, with about a third exposed to past-year intimate partner violence (IPV. The prevalence of current/lifetime PTSD was 19%. In multiple logistic regression, recent life stressors were significantly associated with lifetime trauma, when controlling for SES, study site, and recent IPV. Childhood trauma and recent stressors were significantly associated with PTSD, controlling for SES and study site. While no association was observed between maternal PTSD and birth outcomes, maternal trauma was significantly associated with a 0.3 unit reduction (95% CI: 0.1; 0.5 in infant head-circumference-for-age z-scores (HCAZ scores at birth in crude analysis, which remained significant when adjusted for study site and recent stressors in a multivariate regression model. Conclusions: In this exploratory study

    Several chemical UV filters/absorbers ('UV filters' hereafter) have endocrine-disrupting properties in vitro and in vivo . Exposure to these chemicals, especially during prenatal development, is of concern. To examine maternal exposure to UV filters, associations with maternal thyroid hormone, with growth factor concentrations as well as to birth outcomes. Prospective study of 183 pregnant women with 2nd trimester serum and urine samples available. Maternal concentrations of the chemical UV filters benzophenone-1 (BP-1) and benzophenone-3 (BP-3) in urine and 4-hydroxy-benzophenone (4-HBP) in serum were measured by liquid chromatography-tandem mass spectrometry (LC-MS/MS). The relationships between 2nd trimester maternal concentrations of the three chemical UV filters and maternal serum concentrations of thyroid hormones and growth factors, as well as birth outcomes (weight, height, and head and abdominal circumferences) were examined. Positive associations between maternal serum concentrations of 4-HBP and triiodothyronine (T 3 ), thyroxine (T 4 ), insulin-like growth factor I (IGF-I) and its binding protein IGFBP3 were observed in mothers carrying male fetuses. Male infants of mothers in the middle 4-HBP exposure group had statistically significantly lower weight and shorter head and abdominal circumferences at birth compared to the low exposure group. Widespread exposure of pregnant women to chemical UV filters and the possible impact on maternal thyroid hormones and growth factors, and on fetal growth, calls for further studies on possible long-term consequences of the exposure to UV filters on fetal development and children's health. © 2018 The authors.

    Work-related risk factors, such as long work hours, and physically demanding work have been suggested to adversely influence pregnancy outcome. The authors aimed to examine associations between various aspects of physically demanding work with fetal growth in different trimesters during pregnancy and the risks of adverse birth outcomes. Associations between physically demanding work and fetal growth were studied in 4680 pregnant women participating in a population-based prospective cohort study from early pregnancy onwards in The Netherlands (2002-2006). Mothers who filled out a questionnaire during mid-pregnancy (response 77% of enrolment) were included if they conducted paid employment and had a spontaneously conceived singleton live born pregnancy. Questions on physical workload were obtained from the Dutch Musculoskeletal Questionnaire and concerned questions on lifting, long periods of standing or walking, night shifts and working hours. Fetal growth characteristics were repeatedly measured by ultrasound and were used in combination with measurements at birth. There were no consistent significant associations between physically demanding work nor working hours in relation to small for gestational age, low birth weight or preterm delivery. Women exposed to long periods of standing had lower growth rates for fetal head circumference (HC), resulting in a reduction of approximately 1 cm (3%) of the average HC at birth. Compared with women working working 25-39 h/week and >40 h/week had lower growth rates for both fetal weight and HC, resulting in a difference of approximately 1 cm in HC at birth and a difference of 148-198 g in birth weight. Long periods of standing and long working hours per week during pregnancy seem to negatively influence intrauterine growth.

    Full Text Available Background: Kangaroo Mother Care (KMC is dened as skin-to-skin contact between a mother and her newborn baby derived from practical similarities to marsupial care giving, proximately exclusive breastfeeding and early discharge from hospital. This concept was proposed as an alternative to conventional methods of care for low birth weight (LBW infants, and in replication to quandaries of earnest overcrowding in Neonatal Intensive Care Units (NICUs. KMC essentially utilizes the mother as a natural incubator Aim and Objectives: The aim was to assess the feasibility, acceptability and the effectiveness of KMC in LBW infants. It avoids agitation routinely experienced in busy ward. Material and Methods: A pilot open-labeled quasi-randomised clinical trial was conducted in Level III NICU of a teaching institution. 60 newborn infants <2500 g, meeting inclusion criteria were alternatively randomised into two groups: Kangaroo Mother Care (KMC and Conventional Methods of Care (CMC. Kangaroo mother care was practiced with minimum total period of eight hours a day intermittently for the intervention group while the controls remained in incubators or cots. Weight, head circumference, length, morbidity episodes, hospital stay, feeding patterns were monitored for all infants till postmenstrual age of 42 weeks in preterm babies or till a weight of 2500 g is achieved in term SGA babies. Results: The pilot study conrmed that trial processes were efcient, the intervention was acceptable (to mothers and nurses and that the outcome measures were appropriate; KMC babies achieved signicantly better growth at the end of the study (For preterm babies, weight, length and head circumference gain were signicantly higher in the KMC group (weight 19.28±2.9g/day, length 0.99±0.56cm/week and head circumference 0.72±0.07 cm/week than in the CMC group (P <0.001.

    Congenital Zika virus infection can cause microcephaly and severe brain abnormalities (1). Congenital Zika syndrome comprises a spectrum of clinical features (2); however, as is the case with most newly recognized teratogens, the earliest documented clinical presentation is expected to be the most severe. Initial descriptions of the effects of in utero Zika virus infection centered prominently on the finding of congenital microcephaly (3). To assess the possibility of clinical presentations that do not include congenital microcephaly, a retrospective assessment of 13 infants from the Brazilian states of Pernambuco and Ceará with normal head size at birth and laboratory evidence of congenital Zika virus infection was conducted. All infants had brain abnormalities on neuroimaging consistent with congenital Zika syndrome, including decreased brain volume, ventriculomegaly, subcortical calcifications, and cortical malformations. The earliest evaluation occurred on the second day of life. Among all infants, head growth was documented to have decelerated as early as 5 months of age, and 11 infants had microcephaly. These findings provide evidence that among infants with prenatal exposure to Zika virus, the absence of microcephaly at birth does not exclude congenital Zika virus infection or the presence of Zika-related brain and other abnormalities. These findings support the recommendation for comprehensive medical and developmental follow-up of infants exposed to Zika virus prenatally. Early neuroimaging might identify brain abnormalities related to congenital Zika infection even among infants with a normal head circumference (4).

    Full Text Available Abstract Background Pregnant women exposed to traffic pollution have an increased risk of negative birth outcomes. We aimed to investigate the size of this risk using a prospective cohort of 970 mothers and newborns in Logan, Queensland. Methods We examined two measures of traffic: distance to nearest road and number of roads around the home. To examine the effect of distance we used the number of roads around the home in radii from 50 to 500 metres. We examined three road types: freeways, highways and main roads. Results There were no associations with distance to road. A greater number of freeways and main roads around the home were associated with a shorter gestation time. There were no negative impacts on birth weight, birth length or head circumference after adjusting for gestation. The negative effects on gestation were largely due to main roads within 400 metres of the home. For every 10 extra main roads within 400 metres of the home, gestation time was reduced by 1.1% (95% CI: -1.7, -0.5; p-value = 0.001. Conclusions Our results add weight to the association between exposure to traffic and reduced gestation time. This effect may be due to the chemical toxins in traffic pollutants, or because of disturbed sleep due to traffic noise.

    Full Text Available Despite increased interest in promoting nutrition during pregnancy, the association between maternal dietary patterns and birth outcomes has been equivocal. We examined maternal dietary patterns during pregnancy as a determinant of offspring’s birth weight-for-length (WLZ, weight-for-age (WAZ, length-for-age (LAZ, and head circumference (HCZ Z-scores in Southern United States (n = 1151. Maternal diet during pregnancy was assessed by seven dietary patterns. Multivariable linear regression models described the association of WLZ, WAZ, LAZ, and HCZ with diet patterns controlling for other maternal and child characteristics. In bivariate analyses, WAZ and HCZ were significantly lower for processed and processed-Southern compared to healthy dietary patterns, whereas LAZ was significantly higher for these patterns. In the multivariate models, mothers who consumed a healthy-processed dietary pattern had children with significantly higher HCZ compared to the ones who consumed a healthy dietary pattern (HCZ β: 0.36; p = 0.019. No other dietary pattern was significantly associated with any of the birth outcomes. Instead, the major outcome determinants were: African American race, pre-pregnancy BMI, and gestational weight gain. These findings justify further investigation about socio-environmental and genetic factors related to race and birth outcomes in this population.

    Shrividya Chellam

    2015-01-01

    Full Text Available Background and Aims: Shoulder arthroscopy requires fluid irrigation, which causes soft-tissue oedema around chest, neck, and arm intraoperatively, leading to postoperative airway complications. We decided to study the incidence of increase in the neck circumference in shoulder arthroscopy and its effects on the airway. Methods: We studied 32 cases of shoulder arthroscopies over a period of 1-year, performed under general anaesthesia with interscalene block. The neck circumference of patients before and after the procedure was measured along with other parameters. The endotracheal tube cuff was deflated at the end of surgery to determine air leak around the tube. The negative leak test suggested airway oedema. Results: Thirty out of 32 patients showed positive air leak test. The average change in neck circumference was 1.17 ± 1.16 cm and all could be extubated uneventfully. Two showed negative leak test with an increase in neck circumference by 4.5 and 6.4 cm and were not extubated. Multiple regression analysis for risk factors showed intraoperative hypertension as a single predictor for an increase in neck circumference. Conclusion: Change in the neck circumference beyond 4 cm may suggest airway compromise and below 4 cm, airway compromise is unlikely even in the presence of extensive soft-tissue oedema around the shoulder, upper arm and chest.

    Analyses of birth parameters worldwide reveal relatively high variability over time, often related to socioeconomic factors. The aim was to determine the existence of inter-generational changes in birth parameters in Kraków (Poland) in recent years and factors responsible. This research analysed data on 7800 newborns (e.g. body length and weight) and their parents in the years 1985-2010. The significance of differences was calculated using ANOVA. To examine the potential effect of environmental factors, MANOVA were used. In the case of birth weight no significant changes were observed. A significant decreasing tendency in birth length from the beginning of the 21st century was shown - this observation is quite rare. Accordingly, BMI increased significantly in the 2000s. A decreasing tendency was observed for head circumference. In the analysed period Poland experienced significant socio-economic changes, which could have partly contributed to the observed changes. Some of the observed trends in birth parameters are recent phenomena and it seems necessary to continue the research to confirm if these changes form a steady trend or are only temporary. Tracking any phenomena related to the development is important for the determination of disruptive factors and the reduction of their adverse effects.

    2008-10-01

    Full Text Available Abstract Background Body volume expands with the positive energy balance associated with the development of adult human obesity and this "growth" is captured by two widely used clinical metrics, waist circumference and body mass index (BMI. Empirical correlations between circumferences, BMI, and related body compartments are frequently reported but fail to provide an important common conceptual foundation that can be related to key clinical observations. A two-phase program was designed to fill this important gap: a geometric model linking body volume with circumferences and BMI was developed and validated in cross-sectional cohorts; and the model was applied to the evaluation of longitudinally monitored subjects during periods of voluntary weight loss. Concepts emerging from the developed model were then used to examine the relations between the evaluated clinical measures and body composition. Methods Two groups of healthy adults (n = 494 and 1499 were included in the cross-sectional model development/testing phase and subjects in two previous weight loss studies were included in the longitudinal model evaluation phase. Five circumferences (arm, waist, hip, thigh, and calf; average of sum, C, height (H, BMI, body volume (V; underwater weighing, and the volumes of major body compartments (whole-body magnetic resonance imaging were measured. Results The evaluation of a humanoid geometric model based a cylinder confirmed that V derived from C and H was highly correlated with measured V [R2 both males and females, 0.97; p 0.5. The scaling of individual circumferences to V/H varied, with waist the highest (V/H~0.6 and calf the lowest (V/H~0.3, indicating that the largest and smallest between-subject "growth" with greater body volume occurs in the abdominal area and lower extremities, respectively. A stepwise linear regression model including all five circumferences2 showed that each contributed independently to V/H. These cross

    Evaluation of the commonly used laboratory and clinical parameters of the newborn shortly after birth. Check thresholds acidemia, and in relation to the method of termination of pregnancy. Retrospective epidemiological study. Department of Obstetrics and Gynecology, University Hospital, Olomouc. Of the 26,869 children born in the years 2000 to 2013 Inclusion criteria (complete clinical and laboratory findings after birth) fulfill 23,471 (87.4%) neonates. Methods for evaluation of newborns included Apgar score calculation and arterial umbilical cord blood pH and lactate analysis. A total of 0.7% (157) of the neonates had severe acidosis pH below 7.00 arterial umbilical cord blood, its prevalence varies annually between 0.1 to 1.1%. Cutoff lactate in relation to pH reserves. Operating cesarean births in particular accounts for more than half of those with worse clinical findings Apgar and pH <7.00, but only 30% supratreshold lactate values. Also worse clinical evaluation after caesarean section is not in accordance with the laboratory findings. Vaginal surgery, especially forceps have a significant share of severe acidosis than cesarean, regardless of their frequency. Risk factor of forceps to pH less 7.00,OR = 9.28 (5.39 -15.77), P = 0.0000000, while caesarean to pH less 7,00 had OR = 1.52 (1.08 to 2.14), P = 0.01408156. The results obtained confirm that acidosis after birth is quite common, although they may not have response on the clinical condition of the newborn after birth. Evaluation of Apgar is little objective for the detection of hypoxia during birth and is influenced by the immaturity of newborn and method of delivery. Lactate levels may contribute to an objective assessment of hypoxia during birth. Values above 6.3 mmol/l can be considered an important indicator of newborn acidosis and birth hypoxia.

    To investigate the association of maternal circulating 25-hydroxyvitamin D3 [25(OH)D3] concentration with pregnancy and birth outcomes. Prospective cohort study. Four geographical areas of Spain, 2003-2008. Of 2382 mother-child pairs participating in the INfancia y Medio Ambiente (INMA) Project. Maternal circulating 25(OH)D3 concentration was measured in pregnancy (mean [SD] 13.5 [2.2] weeks of gestation). We tested associations of maternal 25(OH)D3 concentration with pregnancy and birth outcomes. Gestational diabetes mellitus (GDM), preterm delivery, caesarean section, fetal growth restriction (FGR) and small-for-gestational age (SGA), anthropometric birth outcomes including weight, length and head circumference (HC). Overall, 31.8% and 19.7% of women had vitamin D insufficiency [25(OH)D3 20-29.99 ng/ml] and deficiency [25(OH)D3 < 20 ng/ml], respectively. After adjustment, there was no association between maternal 25(OH)D3 concentration and risk of GDM or preterm delivery. Women with sufficient vitamin D [25(OH)D3 ≥ 30 ng/ml] had a decreased risk of caesarean section by obstructed labour compared with women with vitamin D deficiency [relative risk (RR) = 0.60, 95% CI 0.37, 0.97). Offspring of mothers with higher circulating 25(OH)D3 concentration tended to have smaller HC [coefficient (SE) per doubling concentration of 25(OH)D3, -0.10 (0.05), P = 0.038]. No significant associations were found for other birth outcomes. This study did not find any evidence of an association between vitamin D status in pregnancy and GDM, preterm delivery, FGR, SGA and anthropometric birth outcomes. Results suggest that sufficient circulating vitamin D concentration [25(OH)D3 ≥ 30 ng/ml] in pregnancy may reduce the risk of caesarean section by obstructed labour. © 2014 Royal College of Obstetricians and Gynaecologists.

    Full Text Available The circumference study, as its importance, it is one of the most relevant contents in the Analytical Geometry curriculum. However, the complexity of related concepts to this theme linked to the content fragmentation, it difficulties the students thinking of transforming geometrical problems into equations solution, systems or inequations. Within, in this article we present a partial report of a master research work, of qualitative mode, which aimed to develop and to evaluate an alternative methodology by using musical parody composition to the teaching of Mathematics in trying to contribute to the circumference concepts learning process. For that, we carried out a case study with 36 third year high school students of a public school from the city of Campina Grande, Paraíba. The research work was based and discussed on Brousseau Didactical Situation Theory. It was chosen triangulation technique for the data analyses, collected from interviews, questionnaires and a list of mathematical exercises. We concluded that the parody composition resource allowed the students better understand the concepts of center, ratio, cord and the definition of the general circumference equation, as they were capable to identify the relative positions which a circumference assumes in relation to an equation of a straight line and between two circumferences in the various concepts that differentiated them. Thus, we can state that the musical parody composition as a didactical resource can contribute to the learning of mathematical contents.

    Microsurgical equipment has greatly advanced since the inception of the microscope into the operating room. These advancements have allowed for superior surgical precision and better post-operative results. This study focuses on the use of the Leica HM500 head-mounted microscope for the operating phonosurgeon. The head-mounted microscope has an optical zoom from 2× to 9× and provides a working distance from 300 mm to 700 mm. The headpiece, with its articulated eyepieces, adjusts easily to head shape and circumference, and offers a focus function, which is either automatic or manually controlled. We performed five microlaryngoscopic operations utilizing the head-mounted microscope with successful results. By creating a more ergonomically favorable operating posture, a surgeon may be able to obtain greater precision and success in phonomicrosurgery. Phonomicrosurgery requires the precise manipulation of long-handled cantilevered instruments through the narrow bore of a laryngoscope. The head-mounted microscope shortens the working distance compared with a stand microscope, thereby increasing arm stability, which may improve surgical precision. Also, the head-mounted design permits flexibility in head position, enabling operator comfort, and delaying musculoskeletal fatigue. A head-mounted microscope decreases the working distance and provides better ergonomics in laryngoscopic microsurgery. These advances provide the potential to promote precision in phonomicrosurgery.

    Full Text Available Abstract Background Maternal exposure to air pollution has been related to fetal growth in a number of recent scientific studies. The objective of this study was to assess the association between exposure to air pollution during pregnancy and anthropometric measures at birth in a cohort in Valencia, Spain. Methods Seven hundred and eighty-five pregnant women and their singleton newborns participated in the study. Exposure to ambient nitrogen dioxide (NO2 was estimated by means of land use regression. NO2 spatial estimations were adjusted to correspond to relevant pregnancy periods (whole pregnancy and trimesters for each woman. Outcome variables were birth weight, length, and head circumference (HC, along with being small for gestational age (SGA. The association between exposure to residential outdoor NO2 and outcomes was assessed controlling for potential confounders and examining the shape of the relationship using generalized additive models (GAM. Results For continuous anthropometric measures, GAM indicated a change in slope at NO2 concentrations of around 40 μg/m3. NO2 exposure >40 μg/m3 during the first trimester was associated with a change in birth length of -0.27 cm (95% CI: -0.51 to -0.03 and with a change in birth weight of -40.3 grams (-96.3 to 15.6; the same exposure throughout the whole pregnancy was associated with a change in birth HC of -0.17 cm (-0.34 to -0.003. The shape of the relation was seen to be roughly linear for the risk of being SGA. A 10 μg/m3 increase in NO2 during the second trimester was associated with being SGA-weight, odds ratio (OR: 1.37 (1.01-1.85. For SGA-length the estimate for the same comparison was OR: 1.42 (0.89-2.25. Conclusions Prenatal exposure to traffic-related air pollution may reduce fetal growth. Findings from this study provide further evidence of the need for developing strategies to reduce air pollution in order to prevent risks to fetal health and development.

    Autosomal recessive polycystic kidney disease (ARPKD) is a rare condition with a poor prognosis. We report on a 30-year-old primagravid woman in the 34th) week of gestation who was admitted to our hospital. ARPKD of the foetus had been sonographically suspected since the 26th week of gestation. Ultrasound examination showed big polycystic kidneys on both sides. The non-consanguineous parents wanted a maximum therapy for the infant. Foetal digitalisation because of heart insufficiency and prophylactic lung maturation was started. In the further course, Doppler sonographic values worsened and a Caesarean section was performed in the 34th week of gestation at the demand of the parents and due to the expected problems in case of a vaginal delivery. The weight of the newborn was 3,780 g and the abdominal circumference was 50 cm. The newborn was intubated immediately after birth and artificial ventilation was performed. Extracorporeal membrane oxygenation was not possible due to the bad cardial condition. The boy died 16 h after delivery. The parents refused genetic examination and autopsy of the newborn. ARPKD is a severe disease that may have obstetric relevance, due to the massively increased abdominal circumference. Therefore, termination of pregnancy or preterm induction of labor should be considered in order to avoid Caesarean section. Additionally, early prenatal diagnosis with genetic analysis of PRKD1 in cases of suspected ARPKD can be helpful. Georg Thieme Verlag KG Stuttgart, New York.

    To determine the characteristics of obese children presenting at a tertiary care hospital and the frequency of metabolic syndrome (MS) in them using two paediatric definitions. A total of 262 obese children aged 4-16 years, with BMI greater than 95 percentile were included. Children having obesity due to syndromes, medications causing weight gain, chronic illness and developmental disability were excluded. Blood pressure, waist circumference, fasting triglycerides, HDL, insulin and glucose levels were obtained. Obesity was defined as BMI > 95 percentile for age and gender according to the UK growth reference charts. The prevalence of metabolic syndrome was estimated using to the De Ferrantis and Lambert definitions. The frequency of MS varied between 16% and 52% depending on whether insulin levels were included in the definition. There was a significant positive correlation(r) when the metabolic parameters were correlated with waist circumference and insulin levels, except HDL which was negatively correlated. All the metabolic parameters like waist circumference, triglycerides, high density lipoprotein cholesterol and systolic blood pressure increased considerably across the insulin quartile (p < 0.05). The most noteworthy anthropometric and metabolic abnormality were the waist circumference (46.5%) and insulin levels (58%) respectively. There was a marked difference in the frequency of metabolic syndrome according to the definition used. The waist circumference and hyperinsulinemia are significant correlates of MS in obese children. There is a need for establishing normal insulin ranges according to age, gender and pubertal status. The clinical examination and investigations ought to include waist circumference and insulin levels together as a part of the definition of MS, for early detection and intervention of childhood obesity.

  9. BIRTH WEIGHT : A COMMUNITY PERSPECTIVE

    2003-06-01

    Full Text Available India has a dubious distinction of belonging to the top bracket of countries with a very high under-5 Mortality Rate (U5MR of above 96/1000 live births. The U5MR considered the single most significant basic indicator of health status of a community, is proportional to the Infant Mortality Rate (IMR which in turn is contributed to directly and indirectly by the incidence of low Birth Weight (LB W.About 25 million LB W are born each year consisting 17% of all live births,nearly 95% of them in developing countries. About 26% of newborns are LBW in India, and indeed over 16% in those countries with very high U5MR.Both preterm and small-for-dates almost equally make up this category of vulnerable infants predisposed to asphyxia, feeding problems, anemia and growth failure.Considering the close relationship of birth weight with perinatal and infant morbidity as well as mortality, it is crucial to identify the liigh risk groups of low birth weight babies as early as possible.Unfortunately, in a community where 80% of newborns never get to have their weight measured, this itself is a tall order. In our society, the cry of the newborn is greeted with anxious queries about the sex of the baby and not his well­being and potential for healthy survival. The basic concept of the importance of birth weight is missing even among educated families. Indeed, it is as if the weighing machine has no place in the requirements at childbirth. In the absence of this basic facility, field workers and TBAs must report to other means to identify babies at risk. Mid-arm circumference, thigh circumference, foot length, and skin-fold thickness etc. are measurements that have been correlated satisfactorily with the baby’s weight. Simple tools like coloured strips have been developed and these show promise of applicability in field situation for identification of LB W by TBAs for early referral.

    Boron is a metalloid found at highly varying concentrations in soil and water. Experimental data indicate that boron is a developmental toxicant, but the few human toxicity data available concern mostly male reproduction. To evaluate potential effects of boron exposure through drinking water on pregnancy outcomes. In a mother-child cohort in northern Argentina (n=194), 1-3 samples of serum, whole blood and urine were collected per woman during pregnancy and analyzed for boron and other elements to which exposure occurred, using inductively coupled plasma mass spectrometry. Infant weight, length and head circumference were measured at birth. Drinking water boron ranged 377-10,929μg/L. The serum boron concentrations during pregnancy ranged 0.73-605μg/L (median 133μg/L) and correlated strongly with whole-blood and urinary boron, and, to a lesser extent, with water boron. In multivariable-adjusted linear spline regression analysis (non-linear association), we found that serum boron concentrations above 80μg/L were inversely associated with birth length (B-0.69cm, 95% CI -1.4; -0.024, p=0.043, per 100μg/L increase in serum boron). The impact of boron appeared stronger when we restricted the exposure to the third trimester, when the serum boron concentrations were the highest (0.73-447μg/L). An increase in serum boron of 100μg/L in the third trimester corresponded to 0.9cm shorter and 120g lighter newborns (p=0.001 and 0.021, respectively). Considering that elevated boron concentrations in drinking water are common in many areas of the world, although more screening is warranted, our novel findings warrant additional research on early-life exposure in other populations.

    Full Text Available Background: Growth is one of the most important indices in child health. The best and most effective way to investigate child health is measuring the physical growth indices such as weight, height and head circumference. Among these measures, weight growth is the simplest and the most effective way to determine child growth status. Weight trend at a given age is the result of cumulative growth experience, whereas growth velocity represents what is happening at the time. Methods: This longitudinal study was conducted among 606 children repeatedly measured from birth until 2 years of age. We used linear mixed model to analyze repeated measures and to determine factors affecting the growth trajectory. LOWESS smooth curve was used to draw velocity curves. Results: Gender, child rank, birth status and feeding mode had a significant effect on weight trajectory. Boys had higher weight during the study. Infants with exclusive breast feeding had higher weight than other infants. Boys had higher growth velocity up to age 6 month. Breast fed infants had higher growth velocity up to 6 month, but thereafter the velocity was higher in other infants. Conclusions: Many of the studies have investigated child growth, but most of them used cross-sectional design. In this study, we used longitudinal method to determine effective factors on weight trend in children from birth until 2-year-old. The effects of perinatal factors on further growth should be considered for prevention of growth disorders and their late complications.

    Premature and low birth weight children have a high prevalence of academic difficulties. This study examines a model comprised of cumulative risk factors that allows early identification of these difficulties. This is a secondary analysis of data from a large cohort of premature (mathematics. Potential predictor variables were categorized into 4 domains: sociodemographic, neonatal, maternal mental health and early childhood (ages 3 and 5). Regression analysis was used to create a model to predict reading and mathematics scores. Variables from all domains were significant in the model, predicting low achievement scores in reading (R (2) of 0.49, model p-value mathematics (R (2) of 0.44, model p-value education and income, and Black or Hispanic race (sociodemographic); lower birth weight and male gender (neonatal); lower maternal responsivity (maternal mental health); lower intelligence, visual-motor skill and higher behavioral disturbance scores (early childhood). Lower mathematics scores were predicted by lower maternal education, income and age and Black or Hispanic race (sociodemographic); lower birth weight and higher head circumference (neonatal); lower maternal responsivity (maternal mental health); lower intelligence, visual-motor skill and higher behavioral disturbance scores (early childhood). Sequential early childhood risk factors in premature and LBW children lead to a cumulative risk for academic difficulties and can be used for early identification.

    Adverse postnatal health effects have been associated with compromised fetal growth, which makes it essential to understand its determinants. Significant effects of environmental pollutants on birth outcomes have been observed in our study population, and nutritional status may be an additional factor influencing fetal development and effects of environmental toxins. The objective of the study was to examine the relations between birth outcomes and lipid-soluble plasma micronutrient concentrations and to explore interactions between micronutrients and environmental pollutant exposure in newborns in Krakow, Poland. In this prospective cohort study, retinol, alpha-tocopherol, and carotenoids were measured in maternal and cord blood samples obtained at delivery (251 maternal-newborn pairs), and birth weight, birth length, head circumference (HC), and gestational age were evaluated. Linear regression analysis was used to estimate the effects of micronutrients while covariates were controlled for. Interaction terms assessed whether the effects of polycyclic aromatic hydrocarbons (PAHs), common environmental pollutants, varied by nutrient status. Infants whose mothers had low plasma alpha-tocopherol concentrations (below the median) weighed 92.9 g less and had 0.41-cm smaller HCs than did infants whose mothers had high alpha-tocopherol concentrations. Infants with low plasma retinol (below the median) weighed 125.9 g less and had 0.31-cm smaller HCs. There was no evidence of an interaction between PAHs and micronutrients, although power was limited. Maternal alpha-tocopherol and cord retinol concentrations were significantly and positively associated with BW and HC. These micronutrients may have direct effects or may be markers for other underlying determinants of these pregnancy outcomes.

    Betaine supplementation results in lower body weight and fat mass and higher lean mass in animals and adult humans. However, the relation between maternal betaine status and offspring birth weight and body composition is less known. The aim was to examine the association between maternal betaine status and neonatal birth size and adiposity in an Asian mother-offspring cohort. We included 955 pregnant women whose plasma betaine concentrations were measured at 26-28 wk of gestation. Neonatal anthropometric values were measured at birth, and abdominal adipose tissue compartments were assessed by MRI in a subset of infants (n = 307) in the first 14 d after birth. Multivariate general linear models were used to adjust for gestational age; fetal sex; and maternal age, height, education, ethnicity, prepregnancy body mass index, and plasma folate, vitamin B-12, and choline concentrations. The mean ± SD plasma concentration of betaine was 13.2 ± 2.7 μmol/L (range: 5.3-25.0 μmol/L). After adjustment for covariates, higher maternal plasma betaine was associated with lower birth weight (β: -57.6 g; 95% CI: -109.9, -5.3 g), shorter birth length (β: -0.29 cm per 5-μmol/L increment; 95% CI: -0.55, -0.03 cm), smaller head circumference (-0.20 cm; 95% CI: -0.38, -0.02 cm), smaller midupper arm circumference (-0.16 cm; 95% CI: -0.30, -0.03 cm), lower volumes of abdominal superficial subcutaneous adipose tissue (-4.53 mL; 95% CI: -8.70, -0.36 mL), and a higher risk of small-for-gestational-age birth (OR: 1.57; 95% CI: 1.05, 2.35). Higher maternal betaine status was generally associated with smaller infant birth size and less abdominal fat mass. Further studies are needed to replicate these findings and to understand their biological mechanisms.

    Full Text Available Abstract Background People who originate from the Indian subcontinent (South Asians suffer among the highest rates of type 2 diabetes in the world. Prior evidence suggests that metabolic risk factors develop early in life and are influenced by maternal and paternal behaviors, the intrauterine environment, and genetic factors. The South Asian Birth Cohort Study (START will investigate the environmental and genetic basis of adiposity among 750 South Asian offspring recruited from highly divergent environments, namely, rural and urban India and urban Canada. Methods Detailed information on health behaviors including diet and physical activity, and blood samples for metabolic parameters and DNA are collected from pregnant women of South Asian ancestry who are free of significant chronic disease. They also undergo a provocative test to diagnose impaired glucose tolerance and gestational diabetes. At delivery, cord blood and newborn anthropometric indices (i.e. birth weight, length, head circumference and skin fold thickness are collected. The mother and growing offspring are followed prospectively and information on the growth trajectory, adiposity and health behaviors will be collected annually up to age 3 years. Our aim is to recruit a minimum of 750 mother-infant pairs equally divided between three divergent environments: rural India, urban India, and Canada. Summary The START cohort will increase our understanding of the environmental and genetic determinants of adiposity and related metabolic abnormalities among South Asians living in India and Canada.

    Nutrition has been found to be associated with cognitive impairment, but it has not been established whether these associations are present solely in later life or whether they are present in younger age as well. HC is a good indicator of brain development and the most sensitive anthropometric indicator of prolonged malnutrition during early life. This study examined the interaction between early HC and later (nutrition screening initiative) nutritional factors on the risk of cognitive decline in the elderly. The longitudinal factorial design had the mini-mental state examination (MMSE) score as the dependent variable, with HC as one factor and nutritional risk as another. We studied a sample of 495 not cognitively impaired Korean participants with 2 years follow-up data. After multivariable adjustment, interactive effect between HC and nutritional risk was significantly associated with cognitive decline (F=2.449, p=0.045). Simple main effect analysis showed that compared with highest HC, lowest HC was associated with a cognitive decline.

    To investigate the physical growth and psychomotor development of very low birth weight (VLBW) preterm infants in the first year after birth and related influencing factors. A total of 61 VLBW preterm infants received growth and development monitoring for 12 months. Z score was used to evaluate parameters for physical growth, and Denver Development Screen Test (DDST) was used for development screening. Among the 61 VLBW preterm infants, 27 (44.3%) were small-for-gestational-age (SGA) infants, and 34 (55.7%) were appropriate-for-gestational-age (AGA) infants. During the 1-year follow-up, the median weight-for-age Z-score (WAZ), height-for-age Z-score (HAZ), head circumference-for-age Z-score (HCZ), and weight-for-height Z score (WHZ) were >-1 SD in all age groups. The peaks of body mass index-for-age Z-score (BAZ) and WHZ appeared at 1 month of corrected age. At a corrected age of 40 weeks, the incidence rates of underweight, growth retardation, emaciation, microcephalus, overweight, and obesity were 15%, 16%, 11%, 13%, 20%, and 10%, respectively. Compared with those with a corrected age of 40 weeks, the infants with a corrected age of 6 months or 9-12 months had a significantly reduced incidence rate of overweight (3%) (P<0.05). Up to 1 year after birth, 15 infants (25%) had abnormal developmental quotient (DQ). The SGA group had a significantly higher incidence rate of abnormal DQ than the AGA group (P<0.05). SGA was the independent risk factor for retarded growth in the first year after birth in VLBW preterm infants. VLBW preterm infants experience an obvious growth deviation within 3 months of corrected age. Within the first year after birth, the proportion of infants with abnormal DQ screened by DDST is high.

    Low birthweight increases the risk of infant mortality, morbidity and poor development. Maternal nutrition and stress influence birth size, but their combined effect is not known. We hypothesised that an early-invitation time to start a prenatal food supplementation programme could reduce the negative influence of prenatal maternal stress on birth size, and that effect would differ by infant sex. A cohort of 1041 pregnant women, who had delivered an infant, June 2003-March 2004, was sampled from among 3267 in the randomised controlled trial, Maternal Infant Nutritional Interventions Matlab, conducted in Matlab, Bangladesh. At 8 weeks gestation, women were randomly assigned an invitation to start food supplements (2.5 MJ d(-1) ; 6 days a week) either early (∼9 weeks gestation; early-invitation group) or at usual start time for the governmental programme (∼20 weeks gestation; usual-invitation group). Morning concentration of cortisol was measured from one saliva sample/woman at 28-32 weeks gestation to assess stress. Birth-size measurements for 90% of infants were collected within 4 days of birth. In a general linear model, there was an interaction between invitation time to start the food supplementation programme and cortisol with birthweight, length and head circumference of male infants, but not female infants. Among the usual-invitation group only, male infants whose mothers had higher prenatal cortisol weighed less than those whose mothers had lower prenatal cortisol. Prenatal food supplementation programmes that begin first trimester may support greater birth size of male infants despite high maternal stress where low birthweight is a public health concern. © 2013 John Wiley & Sons Ltd.

    Full Text Available OBJECTIVES: To examine whether the adverse effects of slow prenatal and postnatal growth on cognitive function persist to old age and predict age related cognitive decline. DESIGN AND SETTING: A longitudinal birth cohort study of men born in Helsinki, Finland 1934-44. PARTICIPANTS: Nine-hundred-thirty-one men of the Helsinki Birth Cohort Study, with detailed data on growth from birth to adulthood, aged 20.1 (SD = 1.4 at the first and 67.9 (SD = 2.5 years at the second cognitive testing. MAIN OUTCOME MEASURES: The Finnish Defense Forces Basic Intellectual Ability Test assessed twice over nearly five decades apart. RESULTS: Lower weight, length and head circumference at birth were associated with lower cognitive ability at 67.9 years (1.04-1.55 points lower ability per each standard deviation [SD] unit decrease in body size, 95% Confidence Interval [95%CI]: 0.05 to 2.72 and with cognitive decline after 20.1 years (0.07-0.11 SD decline over time per each SD decrease in body size, 95%CI:0.00 to 0.19. Men who were born larger were more likely to perform better in the cognitive ability test over time (1.22-1.43 increase in odds to remain in the top relative to the lower two thirds in ability over time per each SD increase in body size, 95%CI:1.04 to 1.79 and were more resilient to cognitive decline after 20.1 years (0.69 to 0.76 decrease in odds to decline from than remain in the top third of ability over time per each SD increase in body size, 95%CI:0.49 to 0.99. Slower growth between birth and two years in weight, height and body mass index was associated with lower cognitive ability at 67.9 years, but not with cognitive decline. CONCLUSIONS: Poorer lifetime cognitive ability is predicted by slower growth before and after birth. In predicting resilience to age related cognitive decline, the period before birth seems to be more critical.

    Low birth weight (LBW, third of newborn infants in rural south Asia and compromises child survival, infant growth, educational performance and economic prospects. We aimed to assess the impact on birth weight and weight-for-age Z-score in children aged 0-16 months of a nutrition Participatory Learning and Action behaviour change strategy (PLA) for pregnant women through women's groups, with or without unconditional transfers of food or cash to pregnant women in two districts of southern Nepal. The study is a cluster randomised controlled trial (non-blinded). PLA comprises women's groups that discuss, and form strategies about, nutrition in pregnancy, low birth weight and hygiene. Women receive up to 7 monthly transfers per pregnancy: cash is NPR 750 (~US$7) and food is 10 kg of fortified sweetened wheat-soya Super Cereal per month. The unit of randomisation is a rural village development committee (VDC) cluster (population 4000-9200, mean 6150) in southern Dhanusha or Mahottari districts. 80 VDCs are randomised to four arms using a participatory 'tombola' method. Twenty clusters each receive: PLA; PLA plus food; PLA plus cash; and standard care (control). Participants are (mostly Maithili-speaking) pregnant women identified from 8 weeks' gestation onwards, and their infants (target sample size 8880 birth weights). After pregnancy verification, mothers may be followed up in early and late pregnancy, within 72 h, after 42 days and within 22 months of birth. Outcomes pertain to the individual level. Primary outcomes include birth weight within 72 h of birth and infant weight-for-age Z-score measured cross-sectionally on children born of the study. Secondary outcomes include prevalence of LBW, eating behaviour and weight during pregnancy, maternal and newborn illness, preterm delivery, miscarriage, stillbirth or neonatal mortality, infant Z-scores for length-for-age and weight-for-length, head circumference, and postnatal maternal BMI and mid-upper arm

    To assess the consequences on body composition of increasing birth weight in Indian babies in relation to reported values in Western babies, and to assess the relationship between maternal and neonatal anthropometry and body composition. Prospective observational study. Bangalore City, India. A total of 712 women were recruited at 12.5+/-3.1 weeks of gestation (mean+/-standard deviation, SD) and followed up until delivery; 14.5% were lost to follow-up. Maternal body weight, height, mid upper-arm circumference and skinfold thicknesses were measured at recruitment. Weight and body composition of the baby (skinfold thicknesses, mid upper-arm circumference, derived arm fat index and arm muscle index; AFI and AMI, respectively) were measured at birth in hospital. The mean+/-SD birth weight of all newborns was 2.80+/-0.44 kg. Birth weight was significantly related to the triceps and subscapular skinfold thickness of the baby. In a small number of babies with large birth weight for gestational age, there was a relatively higher normalised AFI relative to AMI than for babies with lower or appropriate birth weight for gestational age. Maternal height and fat-free mass were significantly associated with the baby's length at birth. Skinfold thicknesses in Indian babies were similar to those reported in a Western population with comparable birth weights, and the relationship of AFI to birth weight appeared to be steeper in Indian babies. Thus, measures to increase birth weight in Indian babies should take into account possible adverse consequences on body composition. There were no significant relationships between maternal anthropometry and body composition at birth on multivariate analysis, except for sum of the baby's skinfold thicknesses and maternal fat-free mass (P<0.02).

    Despite the marked decline in Singapore's crude birth rate from 42.7/1000 population to 22.1/1000 population from 1957 to 1970, the government adopted a policy of sterilization by coercion with the passage in 1970 of the Voluntary Sterilisation Act. Although sterilization is supposedly voluntary, various regulations make it extremely difficult for couples who wish to retain their fertility. Couples under 40 years of age with more than 2 children must agree to accept sterilization or their children are assigned to a low priority category in regard to primary school admittance. An individual who wishes to marry a non-Singaporean cannot obtain a marriage application unless one of the parties to the marriage agrees to have a sterilization after the birth of their 2nd child. Singapore, with a population density of almost 4000/square kilometer, needs to be concerned about population growth; however, since the population had for the most part already adopted a 2 child family norm, these coercive policies appear to be blatantly excessive.

    Full Text Available The objective of this study is to determine the growth parameters and nutritional biochemical markers and complications of fortification of human milk by post discharge formula of preterm very low birth weight newborns (VLBW. Fifty preterm infants less than 37 weeks with weight less than 1500 g were enrolled in the study. They received parental nutrition and feeding according to our protocol. When enteral feeding reached 100 cc/kg/day, infants were randomized into two groups: group I, Cases, n=25, where post discharge formula (PDF was used for fortification, group II, Controls, n=25 with no fortification. Infants of both groups were given 50% of required enteral feeding as premature formula. This protocol was used until infants’ weight reached 1800 g. Daily weight, weekly length and head circumference were recorded. Hemoglobin, albumin (Alb, electrolytes, blood urea nitrogen (BUN and clinical complications were documented. Human milk fortification with PDF resulted in better growth with increase in weight 16.8 and 13.78 g/kg/day (P=0.0430, length 0.76 and 0.58 cm/week (P=0.0027, and head circumference of 0.59 and 0.5 cm/week (P=0.0217 in cases and controls respectively. Duration of hospital stay was less in cases (22.76 versus 28.52 days in Controls, P=0.02. No significant changes were found in serum electrolytes, BUN, or Alb between both groups. Hemoglobin was significantly higher in Cases, P=0.04. There were no significant clinical complications. Our feeding protocol of fortification of human milk with PDF in preterm very low birth weight newborns resulted in better growth and decrease in length of hospital stay. The use of PDF could be an alternative option for fortification of mothers’ milk for preterm VLBW infants in developing countries with low resources.

    The purpose of this study was to create a reference range nomogram of foetal neck circumference (FNC) and foetal neck area (FNA) in a Nigerian population using polynomial regression models. This cross-sectional study involved 723 pregnant women between 14 and 40 weeks of gestation. Axial measurements of the FNC and FNA were obtained in three measurements and the mean taken as the final value and the 5th, 50th and 95th percentiles for each foetal gestational age (FGA) were calculated. FNC and FNA correlated strongly with FGA, biparietal diameter, abdominal circumference, head circumference, and femoral length. Cubic models fitted the FNC vs FGA, and FNA vs. FGA values, and the mathematical relationships are given as: [Formula: see text] [Formula: see text] [Formula: see text]. Nomograms of FNC and FNA are thus generated. Impact statement The foetal neck circumference (FNC) and foetal neck area (FNA) can serve as predictors of foetal gestational age (FGA) since they correlate strongly and positively with FGA and known biometric parameters. The measurements obtained vary with the population studied. This study provides a nomogram of the FNA and FNC for an African population. The values correlate with that of the Caucasian population up to 32 weeks FGA. Interestingly, FNA and FNC measurements demonstrate high correlation but poor agreement in measurements between sonographers. Even though FNA and FNC could be used as predictors of foetal gestational age, the measurements vary significantly between sonographers. This is attributable to the difficulty in obtaining a satisfactory axial view of foetal neck, which is dependent on foetal presentation.

    Summary West J, Manchester B, Wright J, Lawlor DA, Waiblinger D. Reliability of routine clinical measurements of neonatal circumferences and research measurements of neonatal skinfold thicknesses: findings from the Born in Bradford study. Paediatric and Perinatal Epidemiology 2011. Assessing neonatal size reliably is important for research and clinical practice. The aim of this study was to examine the reliability of routine clinical measurements of neonatal circumferences and of skinfold thicknesses assessed for research purposes. All measurements were undertaken on the same population of neonates born in a large maternity unit in Bradford, UK. Technical error of measurement (TEM), relative TEM and the coefficient of reliability are reported. Intra-observer TEMs for routine circumference measurements were all below 0.4 cm and were generally within ±2-times the mean. Inter-observer TEM ranged from 0.20 to 0.36 cm for head circumference, 0.19 to 0.39 cm for mid upper arm circumference and from 0.39 to 0.77 cm for abdominal circumference. Intra and inter-observer TEM for triceps skinfold thickness ranged from 0.22 to 0.35 mm and 0.15 to 0.54 mm, respectively. Subscapular skinfold thickness TEM values were 0.14 to 0.25 mm for intra-observer measurements and 0.17 to 0.63 mm for inter-observer measurements. Relative TEM values for routine circumferences were all below 4.00% but varied between 2.88% and 14.23% for research skinfold measurements. Reliability was mostly between 80% and 99% for routine circumference measurements and ≥70% for most research skinfold measurements. Routine clinical measurements of neonatal circumferences are reliably assessed in Bradford. Assessing skinfolds in neonates has variable reliability, but on the whole is good. The greater intra-observer, compared with inter-observer, reliability for both sets of measurements highlights the importance of having a minimal number of assessors whenever possible. PMID:21281329

  2. The interplay of variants near LEKR and CCNL1 and social stress in relation to birth size.

    Directory of Open Access Journals (Sweden)

    Anokhi Ali Khan

    Full Text Available BACKGROUND: We previously identified via a genome wide association study variants near LEKR and CCNL1 and in the ADCY5 genes lead to lower birthweight. Here, we study the impact of these variants and social stress during pregnancy, defined as social adversity and neighborhood disparity, on infant birth size. We aimed to determine whether the addition of genetic variance magnified the observed associations. METHODOLOGY/PRINCIPAL FINDINGS: We analyzed data from the Northern Finland Birth Cohort 1986 (n=5369. Social adversity was defined by young maternal age (<20 years, low maternal education (<11 years, and/or single marital status. Neighborhood social disparity was assessed by discrepancy between neighborhoods relative to personal socio-economic status. These variables are indicative of social and socioeconomic stress, but also of biological risk. The adjusted multiple regression analysis showed smaller birth size in both infants of mothers who experienced social adversity (birthweight by -40.4 g, 95%CI -61.4, -19.5; birth length -0.14 cm, 95%CI -0.23, -0.05; head circumference -0.09 cm 95%CI -0.15, -0.02 and neighborhood disparity (birthweight -28.8 g, 95%CI -47.7, -10.0; birth length -0.12 cm, 95%CI -0.20, -0.05. The birthweight-lowering risk allele (SNP rs900400 near LEKR and CCNL1 magnified this association in an additive manner. However, likely due to sample size restriction, this association was not significant for the SNP rs9883204 in ADCY5. Birth size difference due to social stress was greater in the presence of birthweight-lowering alleles. CONCLUSIONS/SIGNIFICANCE: Social adversity, neighborhood disparity, and genetic variants have independent associations with infant birth size in the mutually adjusted analyses. If the newborn carried a risk allele rs900400 near LEKR/CCNL1, the impact of stress on birth size was stronger. These observations give support to the hypothesis that individuals with genetic or other biological risk are more

    A number of studies have reported on the effects of iron supplementation in low birth weight infants; however, no systematic review of the available evidence has been conducted to date. Hence, we performed a systematic review of the literature to examine the effects of iron supplementation on hematologic iron status, growth, neurodevelopment, and adverse effects in low birth weight/premature infants. We searched the Cochrane Library, Medline, and PubMed for articles reporting on the effects of iron supplementation in low weight infants. The following search terms were used: "preterm born infant(s)/children"; "preterm infants"; "prematurely born children" "weight less than 1500 g at birth"; "born prematurely"; "low birth weight infant(s)"; "infants born preterm"; "prematurity"; "small-for-gestational age"; "very small gestational age infants"; "iron supplementation"; "iron intake"; "iron supplements"; "ferric and/or ferrous compounds"; and "ferrous sulphate/fumarate/sulfate". A total of 15 studies were identified and included in the systematic review. Supplemental iron was given orally or as an iron-fortified formula in 14/15 studies. The duration of treatment ranged from 1 week to 18 months. Iron supplementation significantly increased hematologic measures of iron status (including hemoglobin, hematocrit, serum ferritin) relative to placebo or over time in most studies. All controlled studies that examined iron-deficiency anemia (IDA)/ID reported a decreased prevalence of IDA/ID with iron supplementation. Dose dependent decreases in the prevalence of IDA/ID were reported in several studies. Of the 5 studies reporting on growth, none found any significant effect on growth-related parameters (length, height, weight, and head circumference). Only 2 studies reported on neurodevelopment; no marked effects were reported. There were no consistently reported adverse effects, including oxidative stress, inhibited nutrient absorption, morbidity, or the requirement for blood

    Adult leg length is influenced by nutrition in the first few years of life. Adult head circumference is an indicator of brain growth. There is a limited literature linking short legs and small skulls to an increased risk for cognitive impairment and dementia in late life. One phase cross-sectional surveys were carried out of all residents aged over 65 years in 11 catchment areas in China, India, Cuba, Dominican Republic, Venezuela, Mexico and Peru (n = 14,960). The cross-culturally validated 10/66 dementia diagnosis, and a sociodemographic and risk factor questionnaire were administered to all participants, and anthropometric measures taken. Poisson regression was used to calculate prevalence ratios for the effect of leg length and skull circumference upon 10/66 dementia, controlling for age, gender, education and family history of dementia. The pooled meta-analyzed fixed effect for leg length (highest vs. lowest quarter) was 0.82 (95% CI, 0.68-0.98) and for skull circumference 0.75 (95% CI, 0.63-0.89). While point estimates varied between sites, the proportion of the variability attributable to heterogeneity between studies as opposed to sampling error (I2) was 0% for leg length and 22% for skull circumference. The effects were independent and not mediated by family history of dementia. The effect of skull circumference was not modified by educational level or gender, and the effect of leg length was not modified by gender. Since leg length and skull circumference are said to remain stable throughout adulthood into old age, reverse causality is an unlikely explanation for the findings. Early life nutritional programming, as well as neurodevelopment may protect against neurodegeneration.

    Obesity levels have been dramatically increased in the United Arab Emirates over the last few years. High levels of body Mass Index, waist circumference, and percent of total body fat as a measure of obesity have found to be related to cardiovascular risk factors and other diseases. Neck circumference is a new tool that has been linked to obesity. However, no studies in UAE have been conducted yet. The purpose of this study was to measure the obesity levels in a college population and to correlate them with NC and other anthropometrical indexes. Two hundred forty three (243) female students aged 18-25 were conveniently selected to participate in the study. Anthropometrical indexes were obtained from all subjects e after fasting. The prevalence of overweight and obesity together was found to be 28.4 % (n = 69). Pearson correlation showed that WC, NC and BF (%) were significantly positively related to obesity, (r = 0.790; r = 0.758; r = 0.767, p obesity. NC was found to be independently associated with obesity levels in Emirati college students.

    In Norway, external doses of radiation resulting from fallout from the Chernobyl nuclear accident were estimated from detailed measurements, including soil deposition patterns. Internal doses were estimated from measurements of radioactive cesium in meat and milk supplies. The doses were calculated as average monthly doses for each of 454 municipalities during 36 consecutive months after the accident in spring 1986. Prospectively collected data on all newborns listed in the Medical Birth Registry of Norway who were conceived in the period May 1983-April 1989 were used to assess possible dose-response relations between estimated external and food-based exposures and congenital malformations and some other conditions. A positive association was observed between total radiation dose (external plus food-based) and hydrocephaly, while a negative association was observed for Down's syndrome. However, an important conclusion of the study was that no associations were found for conditions previously reported to be associated with radiation, i.e., small head circumference, congenital cataracts, anencephaly, spina bifida, and low birth weight. Potential sources of bias, including exposure misclassification and incomplete ascertainment of cases, are discussed

    2010-12-01

    Full Text Available OBJECTIVE: To describe the maturational development of 20 (aged 32-36 weeks premature newborns (PNBs without clinical or neurological complications from birth until term. METHOD: The Saint-Anne Dargassies Scale was applied every two weeks until the age of 37 weeks. RESULTS: The PNBs showed normal Apgar and the growth in head circumference was adequate for postmentrual age. The Friedman ANOVA test found a significant difference only for the heel-to-ear angles from birth until term. The Saint-Anne Dargassies Scale detected changes in 11 PNBs and the most altered reflexes were: cardinal points, Moro, cross extension reflexe and automatic walking. These changes were found in the first 48 hours of life and in subsequent weeks until term. CONCLUSION: This finding alone justifies the neurological examination of PNBs, even if they show no clinical/neurological complications in the perinatal period and the importance of neuromotor assessment in preterm infants, as it enables detection and appropriate intervention.

    In Norway, external doses of radiation resulting from fallout from the Chernobyl nuclear accident were estimated from detailed measurements, including soil deposition patterns. Internal doses were estimated from measurements of radioactive cesium in meat and milk supplies. The doses were calculated as average monthly doses for each of 454 municipalities during 36 consecutive months after the accident in spring 1986. Prospectively collected data on all newborns listed in the Medical Birth Registry of Norway who were conceived in the period May 1983-April 1989 were used to assess possible dose-response relations between estimated external and food-based exposures and congenital malformations and some other conditions. A positive association was observed between total radiation dose (external plus food-based) and hydrocephaly, while a negative association was observed for Down's syndrome. However, an important conclusion of the study was that no associations were found for conditions previously reported to be associated with radiation, i.e., small head circumference, congenital cataracts, anencephaly, spina bifida, and low birth weight. Potential sources of bias, including exposure misclassification and incomplete ascertainment of cases, are discussed.

    Chest circumference (CC) is suggested to be a good indicator of early life nutrition, but little is known on the heritability of CC. Thus we analysed the effects of genetic and environmental factors on the development of CC in Japanese infants. CC was measured longitudinally from birth until 1 year of age in a cohort of 211 monozygotic and 160 dizygotic complete Japanese twin pairs born in 1989-2002. The data were analysed using applications of structural linear equation modelling for twin data. No sex-specific differences in the variance components were found. Environmental factors unique to each twin explained the major part of the variation of CC at birth whereas environmental factors shared by co-twins were more important at 1-3 months of age. From 3 months of age, the effect of genetic factors become steadily stronger and they explained the majority of the variation at 1 year of age. Strong genetic continuity in the development of CC was found, but also new sets of genes were activated during the first year of life. The origin of the environmental part of the variation could be tracked before 3 months of age. A substantial part of common and specific environmental factors affecting CC affected also birthweight. CC is sensitive to intrauterine environmental factors, but these effects diminish during the first year of life, at least if postnatal environment is good. CC can be a useful indicator when identifying newborns who have suffered suboptimal pre-natal conditions. © 2012 Blackwell Publishing Ltd.

  1. Birth weight and risk of adiposity among adult Inuit in Greenland.

    Directory of Open Access Journals (Sweden)

    Pernille Falberg Rønn

    Full Text Available OBJECTIVE: The Inuit population in Greenland has undergone rapid socioeconomic and nutritional changes simultaneously with an increasing prevalence of obesity. Therefore, the objective was to examine fetal programming as part of the aetiology of obesity among Inuit in Greenland by investigating the association between birth weight and measures of body composition and fat distribution in adulthood. METHODS: The study was based on cross-sectional data from a total of 1,473 adults aged 18-61 years in two population-based surveys conducted in Greenland between 1999-2001 and 2005-2010. Information on birth weight was collected from birth records. Adiposity was assessed by anthropometry, fat mass index (FMI, fat-free mass index (FFMI, and visceral (VAT and subcutaneous adipose tissue (SAT estimated by ultrasound. The associations to birth weight were analyzed using linear regression models and quadratic splines. Analyses were stratified by sex, and adjusted for age, birthplace, ancestry and family history of obesity. RESULTS: Spline analyses showed linear relations between birth weight and adult adiposity. In multiple regression analyses, birth weight was positively associated with BMI, waist circumference, FMI, FFMI and SAT with generally weaker associations among women compared to men. Birth weight was only associated with VAT after additional adjustment for waist circumference and appeared to be specific and inverse for men only. CONCLUSIONS: Higher birth weight among Inuit was associated with adiposity in adulthood. More studies are needed to explore a potential inverse association between birth size and VAT.

    Inconsistent results have been found in prior studies investigating the accuracy of self-reported waist circumference, and no study has investigated the validity of self-reported waist circumference among Japanese individuals. This study used the diagnostic standard of metabolic syndrome to assess the accuracy of individual's self-reported height, weight and waist circumference in a Japanese sample. Study participants included 7,443 Japanese men and women aged 35-79 years. They participated in a cohort study's baseline survey between 2007 and 2011. Participants' height, weight and waist circumference were measured, and their body mass index was calculated. Self-reported values were collected through a questionnaire before the examination. Strong correlations between measured and self-reported values for height, weight and body mass index were detected. The correlation was lowest for waist circumference (men, 0.87; women, 0.73). Men significantly overestimated their waist circumference (mean difference, 0.8 cm), whereas women significantly underestimated theirs (mean difference, 5.1 cm). The sensitivity of self-reported waist circumference using the cut-off value of metabolic syndrome was 0.83 for men and 0.57 for women. Due to systematic and random errors, the accuracy of self-reported waist circumference was low. Therefore, waist circumference should be measured without relying on self-reported values, particularly in the case of women.

    Full Text Available Background: The growth of youth with Down syndrome (DS differs from that of youth without DS, and growth charts specific to DS have been developed. However, little is known about the growth of Brazilian youth with DS. The objective of this study was to construct growth charts for Brazilian youth with DS and compare the growth data with the Child Growth Standards of the World Health Organization (WHO and charts for children with DS from other studies. Methods: Mixed longitudinal and cross-sectional data were collected at University of Campinas, 48 specialized centers for people with intellectual disabilities, and two foundations for people with DS between 2012 and 2015. A total of 10,516 growth measurements from birth to 20 years of age were available from 938 youth with DS (53.7% boys born between 1980 and 2013. The Lambda Mu Sigma method was applied to construct the curves using generalized additive models for location, scale, and shape. Results: Length/height-for-age, weight-for-age, and head circumference-for-age percentile curves were generated for Brazilian boys and girls from birth to 20 years of age. Differences in growth of Brazilian youth ranged from −0.8 to −3.2 z-scores compared to WHO standards, and −1.9 to +1.3 compared to children with DS in other studies. Conclusions: These specific growth charts may guide clinicians and families in monitoring the growth of Brazilian children and adolescents with DS.

    The first 2 years of life is a critical period of rapid growth and brain development. During this period, nutrition and environmental factors play important roles in growth and cognitive development of a child. This report describes the study protocol of early nutrition, growth and cognitive development of infants from birth to 2 years of age. This is a prospective cohort study of mothers and infants recruited from government health clinics in Seremban district in Negeri Sembilan, Malaysia. Infants are followed-up at 6, 12, 18 and 24 months of age. Pre-natal factors that include mother's pre-pregnancy body mass index, gestational weight gain, blood glucose and blood pressure during pregnancy, infant's gestational age, birth weight and head circumference at birth are obtained from patient card. Post-natal factors assessed at each follow-up are feeding practices, dietary intake, anthropometric measurements and cognitive development of infants. Iron status is assessed at 6 months, while infant temperament and home environment are assessed at 12 months. Maternal intelligence is assessed at 18 months. Early life nutritional programming is of current interest as many longitudinal studies are actively being conducted in developed countries to investigate this concept. The concept however is relatively new in developing countries such as Malaysia. This study will provide useful information on early nutrition and infant development in the first two years of life which can be further followed up to identify factors that track into childhood and contribute to growth and cognitive deviations.

  8. Waist circumference threshold values for type 2 diabetes risk.

    Science.gov (United States)

    Friedl, Karl E

    2009-07-01

    Adult gains in body weight, excess adiposity, and intra-abdominal fat have each been associated with risk for type 2 diabetes mellitus (T2DM), forming the basis for preventive medicine guidelines and actuarial predictions using practical indices of weight (e.g., body mass index [BMI]) and waist circumference (WC). As obesity-related disease spreads beyond affluent western countries, application of WC thresholds to other populations has highlighted issues of their generalizability. For example, U.S. national health goals based on BMI technology has provided many great insights into disease, including modern imaging technologies that have differentiated fat depots that have the greatest influence on T2DM, but ultimately, an inexpensive measuring tape provides the most useful and cost-effective preventive measure for T2DM today. At some point in the future, a Star Trek-like abdominal body fat "tricorder" noninvasive assessment of tissue composition may provide an advantage over abdominal girth.

    Limited information is available about the use of neck circumference (NC) to assess obesity in preschool children. This study aims to provide NC percentiles and determine the cut-off levels of NC as a measure to assess obesity in preschool children. The data were obtained from the Anthropometry of Turkish Children aged 0-6 years (ATCA-06) study database. A total of 21 family health centers were chosen and children aged 2-6 years old from all socioeconomic levels were randomly selected from the lists of district midwives; 1766 children (874 male and 892 female; 88.3% of sample size) were included in the study. The smoothed centile curves of NC were constructed by the LMS method. Receiver operating characteristic (ROC) analysis was performed to calculate cut-off points for NC using body mass index ≥95 th percentile. Mean NC was greater in males than females. Cut-off values for obesity were found to be statistically significant in both genders other than 3 years old boys. The NC percentiles of Turkish preschool children were slightly greater than those of other European preschool children in both genders. This difference disappeared around the adiposity rebound period. The 97th percentile values for Turkish preschool children continue to be greater in both genders. NC may be useful to define obesity in preschool children. Since ethnic and various other factors may have a role in incidence of obesity, local reference data are important in assessment of obesity.

Correlations between fat depots and triglyceride or HOMA2-IR, biomarkers of metabolic syndrome, are also reported. Total abdominal fat (TAF, ASF, and IPF masses were measured by magnetic resonance imaging. The highest correlations with WC according to ethnicity and gender were noted for TAF (R2=0.81-0.88 with progressively lower correlations with ASF (0.65–0.82 and IPF (0.29–0.85. The percentage of IPF relative to TAF was not significantly correlated with WC. For all WC categories, higher IPF/ASF ratios were associated with higher triglyceride levels. In contrast, differences in ratios had little or no association with HOMA2-IR. However, when all data were pooled, IPF was positively correlated with both triglyceride (r=0.358 (men and 0.363 (women and HOMA2-IR (r=0.480 (men and 0.517 (women; after adjustment for ASF, IPF was still correlated with triglyceride (r=0.353 (men and 0.348 (women and HOMA2-IR (r=0.290 (men and 0.221 (women. WC measures TAF reliably, but its association with IPF depends on IPF/ASF ratios that vary by gender and ethnicity.

  19. ASSOCIATION OF IDF CRITERIA OF WAIST CIRCUMFERENCE WITH DIABETES MELLITUS IN A RURAL DIABETIC POPULATION

    Directory of Open Access Journals (Sweden)

    Shuba Srinivasan

    2016-09-01

    Full Text Available INTRODUCTION IDF definition of metabolic syndrome uses waist circumference as the main criteria without which metabolic syndrome cannot be diagnosed. The IDF cut-offs for waist circumference is ethnicity specific, but there is a vast heterogeneity amongst South Asians and within the Indian subcontinent itself. MATERIALS AND METHODS This cross-sectional study was conducted on 100 consecutive cases of diabetes in a medical college catering to predominantly rural population who attended the Medicine Department OPD. Demographic data and anthropometric data with relevant biochemical values were collected with patient’s permission and the study was conducted. The IDF criterion of cut-off for waist circumference was solely used to identify the correlation between waist circumference and development of diabetes. RESULTS Study comprised of 55 males and 45 females with diabetes. 40% amongst males with diabetes had a waist circumference below the cut-off for metabolic syndrome. Amongst females, 8% did not fit into the IDF criteria of waist circumference for metabolic syndrome. CONCLUSION Many countries have proposed different cut-off values for waist circumference for diagnosis of metabolic syndrome. India being a heterogenous population requires region and population specific study to identify exact cut-off point. The authors believe 90 cm as waist circumference in males is too high and many metabolic syndrome cases are likely to be missed using this criteria.

    To probe into the physical changes on the head and face of Chinese adults, find the representative indexes and provide references for head-face products design especially in the field of labor protection. The ISO7250-1996 and GB/T5703-99 Basic Human Body Measurements for Technological Design was used. Twenty items of head-face referential parameters and 4 items of body indexes (height, weight, waist circumference and buttock circumference) were measured by using sliding caliper, spreading caliper and pupillometer. The populations were sampled by age, gender and region and their influences on the head and face dimensions were statistically analyzed. By studying the relationship between these parameters with correlation and cluster analysis, the representative indexes of head and face dimensions were concluded. 3000 objectives (2026 men and 974 women) were involved in this survey. The results enunciated that the values of the items in male were larger than those in female. For example, the mean values of face length, face width, jaw width, lip length and nose protrusion were 117.0, 147.6, 118.5, 51.7, 18.7 mm for male and 109.7, 140.1, 114.5, 49.3, 17.7 mm for female. The regional disparity and obesity were significant factors. The sizes of head and face of north-eastern population were significantly bigger than those of south-western population except of maximum length of head, the length of lip and face configuration length. The sizes of head and face of obesity population were significantly bigger than those of non-obesity population (P well represent the head-face dimensions. The influence of gender, region and obesity on the head-face dimensions is significant. The age is not a significant influential factor. Five representative indexes (face length, face width, jaw width, lip length and nose protrusion) are obtained to provide foundation in the standard design of head-face products.

A cohort of infants with birth weight Anemia diagnosis was based on hemoglobin infant formula); hospitalizations during the first year and weight, head circumference, body mass index and length at 12 months' CA were analyzed. Prevalence of anemia in 310 participants was 26.5% [95% confidence interval (CI) 21.8-31.6%] and of iron deficiency was 48% (95% CI 39.0-56.9%). Increased consumption of cow's milk at 6 months [relative risk (RR) 1.687; 95% CI 1.146-2.483], lower maternal age (RR 0.953; 95% CI 0.923-0.983), high number of pregnancies (RR 1.256; 95% CI 1.122-1.406) and being born small for gestational age (RR 1.578; 95% CI 1.068-2.331) were independently associated with anemia after adjustments. Prevalence of anemia is high at 1 year of CA. Dietary and environmental education strategies may help prevent anemia after discharge.

    According Nuranisa, the students' difficulties on a lesson about the circumference of a circle were to understand the concept of what was the circumference of a circle and solve problems associated with the circumference of a circle [8]. According Nuranisa, this is because the teacher only gives a formula to find the circumference of a circle without helping students to construct the formula [8]. The purposes of this study were (1) to develop the hypothetical learning trajectory (HLT) for the cycle circumference material, (2) to describe the student results from the HLT implementation. The type of research used in this research was the design research developed by Gravemeijer and Cobb (2006). According Gravemeijer and Cobb, the design research was divided into three stages: (1) preparing for the experiment, (2) design experiments, and (3) retrospective analysis [6]. In this study, researchers developed the student learning trajectories which were help students to construct their knowledge about the understanding and how to calculate the circumference of a circle. The context used on the students' learning trajectory was sports and arts event. The learning trajectory has been tried out for 15 grade five students on the Budya Wacana elementary school in Yogyakarta. In this paper, researchers would describe how the learning trajectory traversed students to construct their knowledge about the understanding and how to calculate the circumference of the circle and the student thinking process on the understanding and how to calculate the circumference of a circle. The results showed that students could construct about the understanding of the circumference of a circle and how to calculate the circumference of a circle through the student learning trajectory.

    Internet-based interventions are more cost-effective than conventional interventions and can provide immediate, easy-to-access, and individually tailored support for behavior change. Waist circumference is a strong predictor of an increased risk for a host of diseases, such as hypertension, diabetes, and dyslipidemia, independent of body mass index. To date, no study has examined the effect of Internet-based lifestyle interventions on waist circumference change. This study aimed to systematically review the effect of Internet-based interventions on waist circumference change among adults. This meta-analysis reviewed randomized controlled trials (N=31 trials and 8442 participants) that used the Internet as a main intervention approach and reported changes in waist circumference. Internet-based interventions showed a significant reduction in waist circumference (mean change -2.99 cm, 95% CI -3.68 to -2.30, I(2)=93.3%) and significantly better effects on waist circumference loss (mean loss 2.38 cm, 95% CI 1.61-3.25, I(2)=97.2%) than minimal interventions such as information-only groups. Meta-regression results showed that baseline waist circumference, gender, and the presence of social support in the intervention were significantly associated with waist circumference reduction. Internet-based interventions have a significant and promising effect on waist circumference change. Incorporating social support into an Internet-based intervention appears to be useful in reducing waist circumference. Considerable heterogeneity exists among the effects of Internet-based interventions. The design of an intervention may have a significant impact on the effectiveness of the intervention.

    Full Text Available Abstract Background: Epicardial fat is an upper body visceral fat depot that may play a significant role in the development of adverse metabolic and cardiovascular risk profiles. There is a significant direct relationship between the amount of epicardial fat and general body adiposity (body mass index, BMI, but data regarding subcutaneous adiposity is limited. Objective: We conducted a study to determine the association between neck circumference and epicardial fat thickness in healthy young male individuals, and assess their individual correlations with general body adiposity and cardiometabolic risk factors. Methods: One hundred consecutive male patients aged 18 years or older with no known major medical conditions were included in the study. All participants underwent detailed physical examination including measurement of blood pressure, weight, height, waist/hip ratio, and neck circumference. Blood was collected to determine fasting glucose and lipid parameters. A standard echocardiographic examination was performed with additional epicardial fat thickness determination. Results: Among 100 study participants, neck circumference correlated significantly with weight, waist circumference, BMI, blood glucose, serum total cholesterol, low-density (LDL-cholesterol, and triglycerides levels. No significant correlation was found between neck circumference and high-density lipoprotein (HDL-cholesterol levels. Neck circumference correlated moderately and positively with echocardiographic epicardial fat thickness. Conclusion: Among patients with low cardiometabolic risk, increased neck circumference was associated with increased epicardial fat thickness.

    To investigate the relationship between waist circumference and blood pressure (BP) to determine if waist circumference was an indicator of BP in preschool children. Body weight, height, waist circumference (WC), hip circumference, and blood pressure of 939 3-6-year-old preschool children were collected. Systolic blood pressure (SBP) and diastolic blood pressure (DBP) in obese children were significantly higher than that in normal weight children in both sexes (phigh blood pressure in children of both sexes. Multiple linear stepwise regression analysis using SBP as the dependent variable showed that BMI and WC were significant independent factors that influence high blood pressure adjusted for age, WtHr and waist-to-hip circumference ratio (WHr) in boys. When using DBP as the dependent variable, BMI was the only significant independent factor that influenced high blood pressure adjusted for age, WtHr and WHr, in both sex-es. Waist circumference was independently associated with high blood pressure in boys aged 3-6 years. In addition to BMI, increased waist circumference was found to be an indicator of high blood pressure in the preschool children, especially in boys.

    To summarize the available randomized controlled trials (RCTs) to evaluate the effect of taurine supplementation on growth in low birth weight infants (LBW). PubMed, EmBase, and Cochrane Library electronic databases were searched for published articles through March 2017. Analysis was done to examine the effect of taurine supplementation on growth, and sensitivity analysis was performed by removing each individual study from meta-analysis. Results of 9 trials totaling 216 LBW infants in the present meta-analysis were collected and analyzed. The conclusion of included studies demonstrated that taurine supplementation significantly reduced length gain (WMD:-0.18; P supplementation was associated with higher levels of acidic sterols (WMD:0.61; P = 0.024), total fatty acids (WMD:7.94; P = 0.050), total saturated fatty acids (WMD:9.70; P supplementation had little or no significant effect on weight gain, head circumference gain, plasma taurine, threonine, serine, citrulline, valine, methionine, isoleucine, phenylalanine, ornithine, lysine, arginine, glutamate, hydroxyproline, aspartate, dietary cholesterol, endogenous neutral sterols, cholesterol synthesis, and medium-chain triglycerides. The findings suggest that although there are several significant differences in plasma indeces, no significant effect on growth in LBW infants was observed with taurine supplementation.

    Preterm birth is a worldwide epidemic with a global incidence of 15 million per year. Though rates of preterm birth in the United States have declined over the last decade, nearly 1 in 10 babies is still born preterm. The incidence, gestational age, and underlying etiology of preterm birth is highly variable across different racial and ethnic groups and geographic boundaries. In this article, we review the epidemiology of preterm birth in the United States and globally, with a focus on temporal trends and racial, ethnic, and geographic disparities.

    The aim of this study was to analyze the mediation role of cardiorespiratory fitness and waist circumference in the association between muscular strength and cardiometabolic risk. A cross-sectional study involved first-year college students (n = 370) from a Spanish public university was performed. We measured weight, height, waist circumference, blood pressure, biochemical variables, maximum handgrip strength assessment, and cardiorespiratory fitness. We calculated handgrip dynamometry/weight and a previously validated cardiometabolic risk index. Analysis of covariance models was conducted to test differences in cardiometabolic risk values across muscular strength, cardiorespiratory fitness, and waist circumference categories, controlling for confounders. Hayes' PROCESS macro was used for the multiple mediation analysis. The relationship between muscular strength and cardiometabolic risk did not remain significant (c' = 1.76 [1.4]; P > .05) in a multiple serial bootstrapped mediation model including cardiorespiratory fitness and waist circumference as mediators when controlling for age and sex. According to the indirect effect, the significant paths in the model mediating this relationship between muscular strength and cardiometabolic risk index were as follows: muscular strength → waist circumference → cardiometabolic risk index (-4.899; 95% CI: -6.690; -3.450) and muscular strength → cardiorespiratory fitness → waist circumference → cardiometabolic risk index (-0.720; 95% CI: -1.316; -0.360). Both cardiorespiratory fitness and waist circumference mediate the association between muscular strength and cardiometabolic risk in young adults. Thus, our results place cardiorespiratory fitness and waist circumference as the main targets of physical activity programmes aimed at preventing cardiometabolic diseases. © 2018 John Wiley & Sons A/S.

    The purposes of this study were to investigate the association between arm circumference and body mass index (BMI) and to discuss problems, mainly arm circumference and cuff size mismatch, that could affect the reliability of home blood pressure monitoring (HBPM) among peritoneal dialysis (PD) and hemodialysis (HD) patients. 525 PD and 502 HD patients from 16 centers were included in the study. A two-part questionnaire was used to gather information from the participants. Arm circumferences were categorized into four groups according to the British Hypertension Society cuff size recommendations. Mean BMI and arm circumference of all participants were 25.0 kg/m(2) and 27.6 cm, respectively. There was a significant correlation between BMI and arm circumference. The mean BMI and arm circumference values were higher in PD patients than in HD patients. Requirement of a large-sized adult cuff was more common among PD patients compared to HD patients (14 % vs 8 %, p = 0.002). Since HBPM is a useful tool for clinicians to improve BP control, nephrologists should be aware of the problems related to HBPM in dialysis patients and take an active role to increase the reliability of HBPM.

    This report investigated the relationship between anthropometric measurements of body fat distribution and lipid response to statins in hypercholesterolemic hypertensive patients. We prospectively examined 129 subjects who used either simvastatin 20 mg/day (no.=83) or atorvastatin 10 mg/day (no.=46) for 3 months. Anthropometry included evaluation of body mass index, waist and hip circumferences, and waist-to-hip-ratio. Significant decreases in LDL (pcorrelation between waist circumference and HDLcholesterol levels was detected (r=-0.18; p=0.04). Conversely, a direct relationship between hip circumference and HDLcholesterol response to statins was found in the whole sample (r=0.24; p=0.006), while no other anthropometric measurement displayed significant correlation with lipid changes. The association between HDL-cholesterol response and hip circumference was further confirmed by stepwise regression analysis adjusted for baseline HDL-cholesterol levels, metabolic syndrome, body mass index, and waist circumference. Hip circumference, a surrogate marker of peripheral adiposity, is associated with HDL-cholesterol changes following statin therapy in hypertensive patients.

  6. Should waist circumference be replaced by index of central obesity (ICO) in definition of metabolic syndrome?

    2012-01-01

    Waist circumference has been widely used as the parameter of central obesity in defining metabolic syndrome. Global consensus definition of metabolic syndrome has suggested various race- and gender-specific cutoffs of waist circumference for quantifying central obesity. We have earlier proposed that using index of central obesity (ICO), the need for race- and gender-specific cutoffs may be obviated. We propose that waist circumference be supplanted with index of central obesity in all definitions of metabolic syndrome. Using index of central obesity a common cutoff of 0.5 applicable across races and genders might be obtained. Moreover, it will enhance the sensitivity of definition by diagnosing subjects who are shorter than general population. Among 258 male and 242 female diabetic patients, subjects with metabolic syndrome (defined as per gender-specific waist circumference cutoffs), were found to have a common lower range of index of central obesity suggesting that a common cutoff of waist circumference may be obtained. In another study from National Health and Nutrition Examination Survey database, replacing index of central obesity with waist circumference was found to enhance the specificity and sensitivity of definition of metabolic syndrome.

    The aim of the study was to evaluate influence of early nutrition on growth parameters and psychomotor development of children with very low birth weight (VLBW). A prospective clinical study. Institute for Care of Mother and Child, Prague. Thirty nine children of birth weight 1,000-1,499 were followed up to one year of their corrected age in a prospective study. The group was divided in two groups according to type of nutrition: 17 children (group A) were fed with milk of own mother - "preterm milk", 22 children (group B) were orally fed with mature milk from the Bank of mother milk - "term milk", which was fortified with BMF preparation (Nutricia, Netherlands). Both groups were comparable in basic anthropometric parameters (weight, lenght, circumference of head and thotax) and in psychosocial characteristics of their mothers. Growths parameters were monitored in weekly intervals for approximatelly eight weeks. In the period between 11th and 15th month of corrected age, the children were evaluated by a clinical psychologist on a blind basis in mental a motor development by using Bayley Scales of Infant Development (BSID-II). Statistical analysis was performed by chi-square test and t-test. No statistically significant differences between the two groups in evaluating the growth parameters were observed. The psychological examination demonstrated statistically significant differences in the motor development. The psychomotor developmental index (PVI) proved to be 84.4 +/- 14.6 in the group A and 94.3 +/- 12.5 in the group B (t-test = 2.28, pdevelopment between the two groups. The mean mentel developmental index (MVI) was 98.2 +/- 10.2 in the A group and 101.0 +/- 13.3 in the group B. Result of the study indicate favorable effect of fortification of breast milk in VLBW newborns, especially in view of the observed favorable influence of fortfication on motor development of the children.

Patients and methods. The assessment of PG of infants with VLBW (n=92 and ELBW (n=34 was carried out during three time intervals: in the neonatal intensive-care unit (NICU, in the special care nursery and from birth until the hospital discharge. Results. Average PG rates in infants with VLBW and ELBW (the growth of BW, BL and HC in NICU amounted to 8.63 g/day, 0.89 cm/week and 0.4 cm/week respectively; in the special care nursery: 24.2 g/day, 0.94 cm/week, 0.7 cm/week respectively; during the entire treatment period: 18.23 g/day, 0.92 cm/week and 0.6 cm/week respectively. The growth of BW and HC in infants with VLBW and ELBW during the entire treatment period was directly proportional to the growth of BW, BL and HC in NICU; the growth of BW, BL and HC in the special care nursery, as well as the BL growth during the entire treatment period. The growth of PG parameters was inversely proportional to the BW, BL and HC at birth. Conclusion. The PG rates are directly proportional to the growth of all PG parameters and inversely proportional to the PG parameters at birth.

  14. Maternal malaria, birth size and blood pressure in Nigerian newborns: insights into the developmental origins of hypertension from the Ibadan growth cohort.

    Full Text Available Hypertension is an increasing health issue in sub-Saharan Africa where malaria remains common in pregnancy. We established a birth cohort in Nigeria to evaluate the early impact of maternal malaria on newborn blood pressure (BP.Anthropometric measurements, BP, blood films for malaria parasites and haematocrit were obtained in 436 mother-baby pairs. Women were grouped to distinguish between the timing of malaria parasitaemia as 'No Malaria', 'Malaria during pregnancy only' or 'Malaria at delivery', and parasite density as low (<1000 parasites/µl of blood and high (≥ 1000/µl.Prevalence of maternal malaria parasitaemia was 48%, associated with younger maternal age (p<0.001, being primigravid (p = 0.022, lower haematocrit (p = 0.028. High parasite density through pregnancy had the largest effect on mean birth indices so that weight, length, head and mid-upper arm circumferences were smaller by 300 g, 1.1 cm, 0.7 cm and 0.4 cm respectively compared with 'No malaria' (all p ≤ 0.005. In babies of mothers who had 'malaria at delivery', their SBPs adjusted for other confounders were lower respectively by 4.3 and 5.7 mmHg/kg compared with 'malaria during pregnancy only' or 'none'. In contrast the mean newborn systolic (SBP and diastolic BPs (DBP adjusted for birth weight were higher by 1.7 and 1.4 mmHg/kg respectively in babies whose mothers had high compared with low parasitaemia.As expected, prenatal malarial exposure had a significant impact on fetal growth rates. Malaria at delivery was associated with the lowest newborn BPs while malaria through pregnancy, which may attenuate growth of the vascular network, generated higher newborn BPs adjusted for size. These neonatal findings have potential implications for cardiovascular health in sub-Saharan Africa.

    Maternal diet not only provides essential nutrients to the developing fetus but is also a source of prenatal exposure to environmental contaminants. We investigated the association between dietary intake of dioxins and PCBs during pregnancy and birth size. The study included 50,651 women from the Norwegian Mother and Child Cohort Study (MoBa). Dietary information was collected by FFQs and intake estimates were calculated by combining food consumption and food concentration of dioxins, dioxin-like PCBs and non-dioxin-like PCBs. We used multivariable regression models to estimate the association between dietary intake of dioxins and PCBs and fetal growth. The contribution of fish and seafood intake during pregnancy was 41% for dietary dioxins and dioxin-like PCBs and 49% for dietary non-dioxin-like PCBs. Further stratified analysis by quartiles of seafood intake during pregnancy was conducted. We found an inverse dose-response association between dietary intake of dioxins and PCBs and fetal growth after adjustment for confounders. Newborns of mothers in the upper quartile of dioxin and dioxin-like PCBs intake had 62g lower birth weight (95% CI: -73, -50), 0.26cm shorter birth length (95% CI: -0.31, -0.20) and 0.10cm shorter head circumference (95% CI: -0.14, -0.06) than newborns of mothers in the lowest quartile of intake. Similar negative associations for intake of dioxins and dioxin-like PCBs were found after excluding women with intakes above the tolerable weekly intake (TWI=14pg TEQ/kg bw/week). The negative association of dietary dioxins and PCBs with fetal growth was weaker as seafood intake was increasing. No association was found between dietary dioxin and PCB intake and the risk for small-for-gestational age neonate. In conclusion, dietary intakes of dioxins and PCBs during pregnancy were negatively associated with fetal growth, even at intakes below the TWI. © 2013.

    The purpose of this investigation was to clarify the relationship between birth-order position and the development of narcissism, while refining research and theory. The relationship between birth-order status and narcissism was examined with a sample of 79 undergraduate students (55 women and 24 men). These subjects were placed in one of the four following birth-order categories of firstborn, second-born, last-born, and only children. These categories were chosen given their significance in Adlerian theory. Each subject completed the Narcissistic Personality Inventory and a demographic inventory. Based on psychodynamic theory, it was hypothesized that firstborn children were expected to score highest, but statistical significance was not found for an association between narcissism and birth order. Further research is urged to investigate personality theory as it relates to parenting style and birth order.

    Studies of the relationship between serum 25-hydroxyvitamin D (25(OH)D) and changes in measures of adiposity have shown inconsistent results, and interaction with genetic predisposition to obesity has rarely been examined. We examined whether 25(OH)D was associated with subsequent annual changes in body weight (ΔBW) or waist circumference (ΔWC), and whether the associations were modified by genetic predisposition to a high BMI, WC or waist-hip ratio adjusted for BMI (WHRBMI). The study was based on 10,898 individuals from the Danish Inter99, the 1958 British Birth Cohort and the Northern Finland Birth Cohort 1966. We combined 42 adiposity-associated Single Nucleotide Polymorphisms (SNPs) into four scores indicating genetic predisposition to BMI, WC and WHRBMI, or all three traits combined. Linear regression was used to examine the association between serum 25(OH)D and ΔBW or ΔWC, SNP-score × 25(OH)D interactions were examined, and results from the individual cohorts were meta-analyzed. In the meta-analyses, we found no evidence of an association between 25(OH)D and ΔBW (-9.4 gram/y per 10 nmol/L higher 25(OH)D [95% CI: -23.0, +4.3; P = 0.18]) or ΔWC (-0.06 mm/y per 10 nmol/L higher 25(OH)D [95% CI: -0.17, +0.06; P = 0.33]). Furthermore, we found no statistically significant interactions between the four SNP-scores and 25(OH)D in relation to ΔBW or ΔWC. Thus, in view of the narrow CIs, our results suggest that an association between 25(OH)D and changes in measures of adiposity is absent or marginal. Similarly, the study provided evidence that there is either no or very limited dependence on genetic predisposition to adiposity.

    Full Text Available Background Obesity is a worldwide problem and is associated with increased risk of metabolic syndrome. Nutritional status in children has traditionally been determined by body mass index (BMI scores, but with limitations. Upper arm circumference measurement may be a better predictor of energy, protein, and fat storage, as well as a simpler method for screening overweight and obesity in children. Objective To determine the diagnostic value of upper arm circumference compared to BMI for detecting overweight and obesity in children aged 6-7 years. Methods This diagnostic study with a cross-sectional design was performed from September to October 2015 at 16 primary schools in Palembang, Indonesia. We measured the heights, weights, and upper arm circumferences, and calculated BMIs of 2,258 children. Receiver-operator characteristic (ROC curve analysis was used to find an optimal upper arm circumference cut-off point to detect overweight and obesity. Diagnostic value was calculated by using a 2x2 table analysis. Results The prevalences of overweight and obesity were 5.8% and 11.7%, respectively. The optimal upper arm circumference cut-off points for detecting overweight in children aged 6-7 years was 185 mm (sensitivity 88.1% and specificity 78.3%, and for obesity was 195 mm (sensitivity 90.15% and specificity 86.65%. Upper arm circumference had a strong correlation with BMI. Conclusion Upper arm circumference measurement is an accurate method fordistinguishing between normoweight, overweight, and obesity in children aged 6-7 years.

    Full Text Available Abstract Background Because of previously reported ethnic differences in determinants and markers of obesity and related metabolic disorders, we sought to investigate circulating levels of adiponectin and their correlates in a sub-Saharan African (sSA population. Subjects and Methods We studied 70 non-diabetic volunteers (33M/37F living in Yaoundé, Cameroon, aged 24–69 yr, with BMI 20–42 kg/m2. In all participants we measured waist circumference and total body fat by bioimpedance, and obtained a fasting venous blood sample for measurement of plasma glucose, serum insulin and adiponectin concentrations. We performed a euglycaemic hyperinsulinaemic clamp in 1/4 subjects, and HOMAIR was used as surrogate of fasting insulin sensitivity index since it best correlates to clamp measurements. Results Males had lower adiponectin levels than females (8.8 ± 4.3 vs. 11.8 ± 5.5 μg/L. There was no significant correlation between adiponectin and total body fat (rs = -0.03; NS, whereas adiponectin was inversely correlated with waist circumference (rs = -0.39; p = 0.001. Adiponectin correlated negatively with insulin resistance (rs = -0.35; p = 0.01. In a regression analysis using fasting adiponectin concentration as the dependent variable, and age, HOMAIR, waist circumference, and fat mass as predictors, waist circumference (β = -3.30; p = 0.002, fat mass (β = -2.68; p = 0.01, and insulin resistance (β = -2.38; p = 0.02 but not age (β = 1.11; p = 0.27 were independent predictors of adiponectin. When considering gender, these relations persisted with the exception of waist circumference in females. Conclusion Adiponectin correlates in this study population are comparable to those observed in Caucasians with the exception of waist circumference in women. The metabolic significance of waist circumference is therefore questioned in sSA women.

    A wide variety of treatments for circumference reduction and cellulite are available, but most procedures offer suboptimal clinical effect and/or delayed therapeutic outcome. Objective To determine the safety and efficacy of the TriPollar radiofrequency device for cellulite treatment and circumference reduction. Thirty-nine females with cellulite received eight weekly TriPollar treatments. Treatment areas included the abdomen, thighs, buttocks and arms. Subjects were evaluated using standardized photographs and measurements of body weight, circumference, subcutaneous thickness, and skin elasticity of the treatment sites at baseline, immediately after and 4 weeks after the final treatment. Physicians' evaluation of clinical improvement scores using a quartile grading scale was recorded. Thirty-seven patients (95%) completed the treatment protocol. There was significant circumference reduction of 3.5 and 1.7 cm at the abdomen (P = 0.002) and thigh (P = 0.002) regions, respectively. At 4 weeks after the last treatment, the average circumferential reductions of the abdomen and thighs were sustained. No significant circumferential reductions of the buttocks and arms at the last treatment visit compared to baseline were demonstrated (P = 0.138 and 0.152, respectively). Quartile grading scores correlating to approximately 50% improvement in cellulite appearance were noted. Tripollar radiofrequency provided beneficial effects on the reduction of abdomen and thigh circumference and cellulite appearance.

    2015-01-01

    To evaluate the association between calf circumference and gait speed in elderly patients 65 years or older at Geriatric day clinic at Peruvian Centro Médico Naval. Cross-sectional, retrospective study. We assessed 139 participants, 65 years or older at Peruvian Centro Médico Naval including calf circumference, gait speed and Short Physical Performance Battery. With bivariate analyses and logistic regression model we search for association between variables. The age mean was 79.37 years old (SD: 8.71). 59.71% were male, the 30.97% had a slow walking speed and the mean calf circumference was 33.42cm (SD: 5.61). After a bivariate analysis, we found a calf circumference mean of 30.35cm (SD: 3.74) in the slow speed group and, in normal gait group, a mean of 33.51cm (SD: 3.26) with significantly differences. We used logistic regression to analyze association with slow gait speed, founding statistically significant results adjusting model by disability and age. Low calf circumference is associated with slow speed walk in population over 65 years old. Copyright © 2014. Published by Elsevier Espana.

    This study was performed to assess the differences in the birth canal lacerations following the lateral and fours posture deliveries compared with those following the supine posture deliveries. We examined the birth canal lacerations of our "low risk" pregnant women under the midwife-led delivery care at Japanese Red Cross Katsushika Maternity Hospital between April 2006 and March 2015. There were 3826, 1754 and 719 women who delivered with supine, lateral and fours postures. The rate of no laceration in the women who delivered with lateral posture was significant lower than that in the women who delivered with supine posture (OR 0.630, 95% CI 0.56-0.71, p < 0.01); however, the incidence of perineal laceration in the women who delivered with lateral posture was significant lower than that in the women who delivered with supine posture (OR 0.856, 95% CI 0.76-0.90, p < 0.01). The incidence of perineal laceration of third- or fourth-degree in the women who delivered with fours posture was significant higher than that in the women who delivered with supine posture (OR 2.28, 95% CI 1.2-4.2, p < 0.01). The current results may be to help for self-determination of birthing postures in prenatal women.

    Lactose intolerance is a common disease in pediatrics, and its wrong diagnosis will lead to morbidity. The primary objective of this study was to assess the usefulness of an increased waist circumference during the hydrogen breath test as a predictor of lactose intolerance. The secondary objective was to analyze the impact of body mass index, waist circumference measurement, and age on the abdominal distension of patients with lactose intolerance. A total of 138 subjects aged 3 to 15 years were included. They underwent serial measurements of the waist circumference and hydrogen levels in the breath every 30 minutes over 3 hours during the hydrogen breath test. Out of the entire sample, 35 (25.4%) patients had lactose intolerance. An increase of 0.85 cm in waist circumference compared to the baseline waist circumference results in a sensitivity of 88% and a specificity of 85% to predict lactose intolerance (odds ratio: 42.14, 95% confidence interval: 13.08-135.75, p ≤ 0.001). The body mass index and waist circumference measurement did not affect abdominal distension (p= not significant); however, age modified the time of distension. A 0.85 cm increase in waist circumference compared to the baseline waist circumference during the hydrogen breath test is a useful parameter for the diagnosis of lactose intolerance in pediatrics. Variations in relation to body mass index and waist circumference did not affect the usefulness of an increased waist circumference, unlike age.

    Correlate shift work with body mass index (BMI), waist circumference, chronotype and depressive symptoms. This study comprising 14 shift workers and 13 day workers. Subjects were workers from the health area aged 25 to 60 years. Minor psychiatric disorders were accessed by Self Report Questionnaire (SRQ-20) and depressive symptoms by Beck Depression Inventory (BDI). Chronotype was accessed using Morningness-Eveningness Questionnaire (MEQ). Anthropometric measures were taken. Shift workers presented higher BMI (P = 0.03) and waist circumference (P = 0.004) than day workers. Years on shift work were significantly correlated to waist circumference (r = 0.43; P = 0.03) and age (r = 0.47; P = 0.02). Shift work was not correlated with depressive symptoms and chronotype. These results may suggest a role played by shift work on the development and/or the early clinic manifestations of metabolic disturbances, becoming a risk factor to metabolic syndrome.

    Dietary fiber may play a role in obesity prevention. Until now, the role that fiber from different sources plays in weight change had rarely been studied. Our aim was to investigate the association of total dietary fiber, cereal fiber, and fruit and vegetable fiber with changes in weight and waist circumference. We conducted a prospective cohort study with 89,432 European participants, aged 20-78 y, who were free of cancer, cardiovascular disease, and diabetes at baseline and who were followed for an average of 6.5 y. Dietary information was collected by using validated country-specific food-frequency questionnaires. Multiple linear regression analysis was performed in each center studied, and estimates were combined by using random-effects meta-analyses. Adjustments were made for follow-up duration, other dietary variables, and baseline anthropometric, demographic, and lifestyle factors. Total fiber was inversely associated with subsequent weight and waist circumference change. For a 10-g/d higher total fiber intake, the pooled estimate was -39 g/y (95% CI: -71, -7 g/y) for weight change and -0.08 cm/y (95% CI: -0.11, -0.05 cm/y) for waist circumference change. A 10-g/d higher fiber intake from cereals was associated with -77 g/y (95% CI: -127, -26 g/y) weight change and -0.10 cm/y (95% CI: -0.18, -0.02 cm/y) waist circumference change. Fruit and vegetable fiber was not associated with weight change but had a similar association with waist circumference change when compared with intake of total dietary fiber and cereal fiber. Our finding may support a beneficial role of higher intake of dietary fiber, especially cereal fiber, in prevention of body-weight and waist circumference gain.

    Stem diameter is one of the most commonly measured attributes of trees, forming the foundation of forest censuses and monitoring. Changes in tree stem circumference include both irreversible woody stem growth and reversible circumference changes related to water status, yet these fine-scale dynamics are rarely leveraged to understand forest ecophysiology and typically ignored in plot- or stand-scale estimates of tree growth and forest productivity. Here, we deployed automated dendrometer bands on 12-40 trees at four different forested sites-two temperate broadleaf deciduous, one temperate conifer, and one tropical broadleaf semi-deciduous-to understand how tree circumference varies on time scales of hours to months, how these dynamics relate to environmental conditions, and whether the structure of these variations might introduce substantive error into estimates of woody growth. Diurnal stem circumference dynamics measured over the bark commonly-but not consistently-exhibited daytime shrinkage attributable to transpiration-driven changes in stem water storage. The amplitude of this shrinkage was significantly correlated with climatic variables (daily temperature range, vapor pressure deficit, and radiation), sap flow and evapotranspiration. Diurnal variations were typically rain events, likely driven by combinations of increased stem water storage and bark hydration. Particularly at the tropical site, these rain responses could be quite substantial, ranging up to 1.5 mm circumference expansion within 48 hours following a rain event. We conclude that over-bark measurements of stem circumference change sometimes correlate with but have limited potential for directly estimating daily transpiration, but that they can be valuable on time scales of days to weeks for characterizing changes in stem growth and hydration.

    Full Text Available Background and Aim: The need for recrimping precrimped stainless steel crowns by the dentist in clinic is controversial. This study aimed to evaluate the rate of marginal circumference and marginal thickness change of precrimped stainless steel crowns after recrimping. Materials and Methods: In this experimental study, 30 primary photos were taken from margins of 30 S.S.Cs (3M, Ni-Cr related to tooth 85 with a digital camera fixed at a determined distance. Margins of crowns were crimped by 114 and 137 pliers with a controlled force (0.2 N and then 30 secondary photos were taken in the same conditions. The circumference of crown margins in primary (group A and secondary (group B photos were assessed by a digitizer system. Comparing the circumferences of crown margins in primary and secondary photos showed a significant decrease after crimping. Thickness of 30 random points on the crown margins of a crown similar to mentioned cases was measured by SEM (×150. Then similar procedures including taking a primary photo, crimping and taking a secondary photo was done for the sample crown. After significant reduction in margin circumference, thickness of 30 other random points on the crown margin were measured by SEM. Data were analyzed by paired sample t-test with p<0.05 as the limit of significance. Results: The mean marginal circumference of precrimped stainless steel crowns was reduced by 7.3% which was significant (P<0.001. On the other hand the mean marginal thickness of sample stainless steel crown showed 18µ increase. Conclusion: According to the results of this study, marginal circumference of precrimped stainless steel crowns (3M, Ni-Cr showed a significant decrease after crimping. It is concluded that crimping the stainless steel crowns even for precrimped ones seems necessary.

    Cardiovascular risk factors, such as abdominal obesity and obesity in general, are very prevalent among patients with bipolar disorder (BD). Although long-term use of psychotropic medications is an important determinant of these risk factors, other evidence suggests that early development may interact with the mood disorder diathesis to exponentially increase the risk of obesity. The goal of our study was to test whether season of birth is associated with adult body mass index (BMI) and abdominal obesity in individuals with bipolar disorder. We compared season of birth effects on BMI in 375 adult patients with bipolar disorder and 196 adult patients with unipolar major depression. We found a significant season of birth effect on BMI in patients with bipolar disorder, but not unipolar. In patients with bipolar disorder, season of birth was also associated with waist circumference, with a stronger effect in males. Season of birth affects adult BMI and waist circumference in patients with bipolar disorder, but not in patients with unipolar depression. Our results suggest that early environmental factors, yet to be identified, interact with specific neurobiological features of bipolar disorder to determine stable traits and disease risk factors in adult life.

    Cross-cohort comparison is an established method for improving causal inference. This study compared 2 cohorts, 1 from a high-income country and another from a middle-income country, to (1) establish whether birth exposures may play a causal role in the development of childhood attention problems; and (2) identify whether confounding structures play a different role in parent-reported attention difficulties compared with attention deficit hyperactivity disorder (ADHD) diagnoses. Birth exposures included low birth weight (LBW), small-for-gestational age (SGA), small head circumference (HC) and preterm birth (PTB)). Outcomes of interest were attention difficulties (Strengths and Difficulties Questionnaire, SDQ) and ADHD (Development and Well-Being Assessment, DAWBA). Associations between exposures and outcomes were compared between 7-year-old children from the Avon Longitudinal Study of Parents and Children (ALSPAC) in the UK (N=6849) and the 2004 Pelotas cohort in Brazil (N=3509). For attention difficulties (SDQ), the pattern of association with birth exposures was similar between cohorts: following adjustment, attention difficulties were associated with SGA (OR=1.59, 95% CI 1.20 to 2.19) and small HC (OR=1.64, 95% CI 1.11 to 2.41) in ALSPAC and SGA (OR=1.35, 95% CI 1.04 to 1.75) in Pelotas. For ADHD, however, the pattern of association following adjustment differed markedly between cohorts. In ALSPAC, ADHD was associated with LBW (OR=2.29, 95% CI 1.09 to 4.80) and PTB (OR=2.33, 95% CI 1.23 to 4.42). In the Pelotas cohort, however, ADHD was associated with SGA (OR=1.69, 95% CI 1.02 to 2.82). The findings suggest that fetal growth impairment may play a causal role in the development of attention difficulties in childhood, as similar associations were identified across both cohorts. Confounding structures, however, appear to play a greater role in determining whether a child meets the full diagnostic criteria for ADHD. Published by the BMJ Publishing Group Limited

    In this retrospective study of 873 men enrolled for assisted reproduction techniques, relationships between sperm quality parameters, motile sperm organelle morphology examination (MSOME), DNA damage and live birth rate were evaluated. The presence of vacuoles in the sperm heads was detected by MSOME. Either chromatin decondensation or DNA fragmentation was used to study DNA damage. Results show that age significantly affected some of the examined parameters. In particular, sperm concentration was positively correlated (R = 0.088; P = 0.01) and chromatin decondensation was negatively correlated (R = -0.102; P = 0.003) with age. Furthermore, live birth rate was significantly lower in men aged 40 years or older (P vacuoles was not associated with head morphology, main sperm quality parameters, DNA fragmentation and live birth rate. Considering sperm heads in relation to the shape (normal/abnormal) and vacuoles (presence/absence), no significant variations in the occurrence of vacuoles in either normal or abnormal heads were found. These data suggest that vacuoles are physiological features that do not alter sperm functionality, and it seems that MSOME is not necessary for increasing the success of assisted reproduction techniques.

  9. Ethics and "normal birth".

    Science.gov (United States)

    Lyerly, Anne Drapkin

    2012-12-01

    The concept of "normal birth" has been promoted as ideal by several international organizations, although debate about its meaning is ongoing. In this article, I examine the concept of normalcy to explore its ethical implications and raise a trio of concerns. First, in its emphasis on nonuse of technology as a goal, the concept of normalcy may marginalize women for whom medical intervention is necessary or beneficial. Second, in its emphasis on birth as a socially meaningful event, the mantra of normalcy may unintentionally avert attention to meaning in medically complicated births. Third, the emphasis on birth as a normal and healthy event may be a contributor to the long-standing tolerance for the dearth of evidence guiding the treatment of illness during pregnancy and the failure to responsibly and productively engage pregnant women in health research. Given these concerns, it is worth debating not just what "normal birth" means, but whether the term as an ideal earns its keep. © 2012, Copyright the Authors Journal compilation © 2012, Wiley Periodicals, Inc.

    2017-01-01

    Previous research has established that birth order affects outcomes such as educational achievements, IQ and earnings. The mechanisms behind these effects are, however, still largely unknown. In this paper, we examine birth-order effects on health, and whether health at young age could be a transmission channel for birth-order effects observed later in life. We find no support for the birth-order effect having a biological origin; rather firstborns have worse health at birth. This disadvantag...

    The purpose of this study is to describe a healthy life birth after a mosaic embryo transfer in oocyte in vitro maturation (IVM). Patient received minimal stimulation, starting on day 3 after menstrual period. No hCG trigger was administered. Oocyte retrieval was performed and oocytes were matured for 30 h. After denuding, mature oocytes were inseminated by ICSI. Embryos were cultured until blastocyst stage and biopsied. One euploid embryo after array comprehensive genome hybridization (aCGH) was diagnostic. However, the next-generation sequencing (NGS) re-analysis showed that embryo was a mosaic for chromosome 13 and 21. Nevertheless, pregnancy ultrasound scans and non-invasive prenatal test (NIPT-Verifi-Illumina) indicated a normal fetus development. Finally, a healthy baby was born after 38 weeks. Its weight was 4480 g, head circumference 36 cm, and total length of 51 cm. To confirm that the baby was chromosomically normal, an NGS test was performed in buccal cells, a normal profile was obtained. Our finding confirmed that mosaic embryo transfer would bring a healthy offspring.

    Full Text Available Introduction: Evidence suggests a high prevalence of calcium and vitamin D deficiencies exists in both pregnant women and babies. Adequate intake of micronutrients has great importance especially during pregnancy and lactation period. Thus, the present study aimed at assessing the effect of vitamin D and calcium-vitamin D on pregnancy and birth outcomes (including duration of pregnancy, type of delivery and infant anthropometric indicators. Methods: A randomized, controlled, clinical, triple-blind trial conducted on 126 pregnant women referring to Tabriz health centers in 2013-14. Subjects were allocated into three groups using block randomization. Interventional groups received vitamin D, calcium-vitamin D and placebo pills daily for 60 days. ANCOVA and Chi-square tests were used for data analysis. Results: By controlling BMI before and during pregnancy, there were no significant differences between the group in average neonatal weight, height and head circumference, duration of pregnancy, type of delivery and gestational age at the time of delivery. Conclusion: The results show that calcium-vitamin D and vitamin D have no effect on duration of pregnancy, type of delivery and infant anthropometric indicators.

    The present study aimed to: 1) examine the association of biological maturation effect on children's performance at a motor coordination battery and 2) to assess whether the association between biological maturation and scores obtained in motor coordination tests is mediated by some anthropometric measurement. The convenience sample consisted of 73 male children aged 8 years old. Anthropometric data considered the height, body mass, sitting height, waist circumference, body mass index, fat mass and fat-free mass estimates. Biological maturation was assessed by the percentage of the predicted mature stature. Motor coordination was tested by the Körperkoordinationstest für Kinder. A partial correlation between anthropometric measurements, z-score of maturation and the motor coordination tests were performed, controlling for chronological age. Finally, causal mediation analysis was performed. Height, body mass, waist circumference and fat mass showed a slight to moderate inverse correlation with motor coordination. Biological maturation was significantly associated with the balance test with backward walking (r=-0.34). Total mediation of the waist circumference was identified in the association between biological maturation and balance test with backward walking (77%). We identified an association between biological maturation and KTK test performance in male children and also verified that there is mediation of waist circumference. It is recommended that studies be carried out with female individuals and at other age ranges. Copyright © 2016 Sociedade de Pediatria de São Paulo. Publicado por Elsevier Editora Ltda.

    High rates of obesity and chronic disease make establishment of effective indicators of risk for chronic disease important. The objective was to examine adequacy of anthropometric cut-off points as indicators of risk for chronic disease among Samoan women in Hawaii. A cross-sectional survey of 55 Samoan women 18 to 28 years of age that included blood lipids, cholesterol, and glucose (including after a 2-hour oral glucose test); anthropometry (weight, height, waist circumference); and DXA of body composition. Using the Centers for Disease Control and Prevention (CDC)/World Health Organization (WHO) cut-off points for BMI, 22% of women were overweight and 58% were obese. Cholesterol, lipid, and glucose values were all linearly related to DXA body fat, BMI, and waist circumference. BMI and waist circumference at WHO/NIH cut-off points predicted levels of blood lipids and glucose that indicate elevated risk for disease. WHO/NIH cut-off points for BMI and waist circumference reflect risk indicators of chronic disease among young Samoan women in Hawaii.

    Full Text Available Anthropometric indexes such as body mass index (BMI, waist circumference (WC, hip ciucumference (HC, and waist–hip ratio (WHR, are all useful anthropometric measurements to provide important information on blood glucose concentrations. The aim of this study was to determine different anthropometric measurements, in particular BMI, waist circumference, hip circumference and waist-to-hip ratio, in their ability to predict the blood glucose levels in men and women 40 to 60. A cross-sectional study was conducted on a sample of 44 men and 127 women aged 40 to 50 who lived in Cipete Selatan subdistrict, South Jakarta. Blood glucose levels was assessed and anthropometric measurements comprising BMI, WC, HC, WHR were collected. Multiple linear regression analysis was used to determine the best predictor for blood glucose levels. The study showed that the prevalence of DM type 2 was 25.7% and the prevalence was higher in men (40.9% compared to women (23.5%. The significant predictive variables in the simple regression analysis were age and waist circumference. Multiple linear regression showed that after adjustment for age, WC was positively associated with blood glucose levels. Standardized a value was 0.172 (p=0.026. WC predict blood glucose levels, beyond that explained by traditional diabetic risk factors and BMI. These findings provide support for the recommendation that WC be a routine measure for identification of diabetes mellitus type 2 in men and women aged 40 to 60 years.

    Preterm birth (delivery before 37 completed weeks of gestation) is common and rates are increasing. In the past, medical efforts focused on ameliorating the consequences of prematurity rather than preventing its occurrence. This approach resulted in improved neonatal outcomes, but it remains costly in terms of both the suffering of infants and their families and the economic burden on society. Increased understanding of the pathophysiology of preterm labor has altered the approach to this problem, with increased focus on preventive strategies. Primary prevention is a limited strategy which involves public education, smoking cessation, improved nutritional status and avoidance of late preterm births. Secondary prevention focuses on recurrent preterm birth which is the most recognisable risk factor. Widely accepted strategies include cervical cerclage, progesterone and dedicated clinics. However, more research is needed to explore the role of antibiotics and anti-inflammatory treatments in the prevention of this complex problem.

    The molecular mechanisms controlling human birth timing at term, or resulting in preterm birth, have been the focus of considerable investigation, but limited insights have been gained over the past 50 years. In part, these processes have remained elusive because of divergence in reproductive strategies and physiology shown by model organisms, making extrapolation to humans uncertain. Here, we summarize the evolution of progesterone signaling and variation in pregnancy maintenance and termination. We use this comparative physiology to support the hypothesis that selective pressure on genomic loci involved in the timing of parturition have shaped human birth timing, and that these loci can be identified with comparative genomic strategies. Previous limitations imposed by divergence of mechanisms provide an important new opportunity to elucidate fundamental pathways of parturition control through increasing availability of sequenced genomes and associated reproductive physiology characteristics across diverse organisms.

    Exposure to maternal adiposity during pregnancy is associated with higher offspring birth weight and greater adiposity through childhood and adult life. As birth weight reflects the summation of lean and fat mass, the extent to which fat mass at birth tracks into later life is unknown. To determine whether fat mass at birth is associated with child and adolescent adiposity. UK birth cohort with markers of neonatal fat mass; cord blood leptin, adiponectin, and birth weight and adiposity outcomes at age 9 (n = 2775) and 17 years (n = 2138). Offspring body mass index (BMI), waist circumference, dual-energy X-ray absorptiometry-determined fat mass, and obesity at age 9 and 17 years. Higher cord blood leptin was associated with higher z scores of fat mass [difference in mean per 10 pg/mL: 0.03 standard deviation (SD); 95% confidence interval (CI), 0.00 to 0.06], waist circumference (0.04 SD; 95% CI, 0.00 to 0.07), and BMI (0.04 SD; 95% CI, 0.00 to 0.08) at age 9. However, by age 17 the adjusted results were attenuated to the null. Cord blood adiponectin was not associated with measures of adiposity at age 9. At age 17, cord blood adiponectin was positively associated with fat mass (0.02 SD per 10 μg/mL; 95% CI, 0.02 to 0.03) and waist circumference (0.04 SD per 10 μg/mL; 95% CI, 0.03 to 0.05). Birth weight was positively associated with waist circumference (0.03 SD per 100 g; 95% CI, 0.02 to 0.04) and BMI (0.02 SD per 100 g; 95% CI, 0.00 to 0.03), but not fat mass or odds of obesity. Cord blood leptin and adiponectin were not associated with obesity at either age. Increased cord blood leptin and adiponectin, known surrogates of fetal fat mass, were weakly associated with increased fat mass in late childhood and adolescence, respectively.

    To use meta-analytic techniques to quantitatively evaluate the efficacy of orlistat and lorcaserin in the treatment of people who are overweight and obese. We identified publications from searches of electronic databases and extracted data from studies that compared orlistat or lorcaserin to lifestyle advice (standard care), placebo, sibutramine, rimonabant or metformin and collected information on waist circumference change or withdrawals due to adverse events (AEs). A mixed treatment comparison (MTC) meta-analysis was performed on the data extracted. Orlistat was found to be significantly better than placebo and standard care in reducing waist circumference at 6 and 12 months; orlistat reduced waist circumference by -6.96 cm [95% credible interval (CrI): -8.93, -4.96 cm] compared to standard care at 6 months. The results suggested that lorcaserin reduced waist circumference by a greater amount than all other interventions at 12 months, for example, lorcaserin lead to a greater reduction of -2.45 cm (95% CrI: -4.99, 0.08 cm) in comparison to placebo, although these differences were not statistically significant. Although data were very limited, metformin reduced waist circumference by a greater amount (-2.11 cm, 95% CI: -1.00, -3.22 cm) than orlistat at 6 months. On average, 6.5% of patients on orlistat and 5.4% of those on lorcaserin discontinued their treatment due to AEs at 12 months. Orlistat should be considered as an addition to lifestyle interventions in the treatment of obesity. Lorcaserin has recently been approved by the US Food and Drug Administration (FDA) and these results suggest that it is similar in both efficacy and safety compared to orlistat. © 2013 John Wiley & Sons Ltd.

    To assess the effectiveness of an intervention to promote standardized arm circumference measurement as way to choose appropriate cuff size to measure blood pressure. A before-after intervention study was performed in a basic health care area in Barcelona. Doctors, nurses and pharmacy staff participated by filling out an anonymous self-administered questionnaire pre- and post-intervention (3m). Variables included: demographics, type of professional, years since they finished their studies, availability of different cuff sizes, if arm circumference measurement were obtained or not, knowledge about the cutoff values for each cuff size and type of blood pressure monitor. The written results were given to the participants and presented in sessions. Pre- and post-intervention: 74.3 and 67.3% answered the questionnaires (P=ns), respectively. Determination of arm circumference varied from 1.3 to 19.1% (P=.009). A total of 37.3% and 44.1% declared that they had 2 or more available cuff sizes (P=ns). Knowledge about the correct measurement of the cuffs was 2.7 to 33.8% regarding the standard cuff size (P=.0198) and 0 to 23.5% for obese subjects (P<.05). When more than one cuff was available, reasons for the choice went from: «making a rough guess» or «when velcro stops sticking» before and after the intervention. All blood pressure devices in our primary health care center were electronic and automatic as were those of the 9 pharmacies. The intervention increased the determination of arm circumference prior to the reading of the blood pressure and the knowledge about the cutoff interval for standard and obese cuff size after intervention. There was greater availability of different sized cuffs. Despite this, the choice of the appropriate cuff size was not made based on arm circumference. Copyright © 2014 SEHLELHA.

    Adult leg length is influenced by nutrition in the first few years of life. Adult head circumference is an indicator of brain growth. Cross-sectional studies indicate inverse associations with dementia risk, but there have been few prospective studies. Population-based cohort studies in urban sites in Cuba, Dominican Republic Puerto Rico and Venezuela, and rural and urban sites in Peru, Mexico and China. Sociodemographic and risk factor questionnaires were administered to all participants, and anthropometric measures taken, with ascertainment of incident dementia, and mortality, three to five years later. Of the original at risk cohort of 13,587 persons aged 65 years and over, 2,443 (18.0%) were lost to follow-up; 10,540 persons with skull circumference assessments were followed up for 40,466 person years, and 10,400 with leg length assessments were followed up for 39,954 person years. There were 1,009 cases of incident dementia, and 1,605 dementia free deaths. The fixed effect pooled meta-analysed adjusted subhazard ratio (ASHR) for leg length (highest vs. lowest quarter) was 0.80 (95% CI, 0.66-0.97) and for skull circumference was 1.02 (95% CI, 0.84-1.25), with no heterogeneity of effect between sites (I2 = 0%). Leg length measurements tended to be shorter at follow-up, particularly for those with baseline cognitive impairment and dementia. However, leg length change was not associated with dementia incidence (ASHR, per cm 1.006, 95% CI 0.992-1.020), and the effect of leg length was little altered after adjusting for baseline frailty (ASHR 0.82, 95% CI 0.67-0.99). A priori hypotheses regarding effect modification by gender or educational level were not supported. However, the effect of skull circumference was modified by gender (M vs F ASHR 0.86, 95% CI 0.75-0.98), but in the opposite direction to that hypothesized with a greater protective effect of larger skull dimensions in men.

    Over the last several years, as cesarean deliveries have grown increasingly common, there has been a great deal of public and professional interest in the phenomenon of women ‘choosing’ to deliver by cesarean section in the absence of any specific medical indication. The issue has sparked intense conversation, as it raises questions about the nature of autonomy in birth. Whereas mainstream bioethical discourse is used to associating autonomy with having a large array of choices, this conception of autonomy does not seem adequate to capture concerns and intuitions that have a strong grip outside of this discourse. An empirical and conceptual exploration of how delivery decisions ought to be negotiated must be guided by a rich understanding of women’s agency and its placement within a complicated set of cultural meanings and pressures surrounding birth. It is too early to be ‘for’ or ‘against’ women’s access to cesarean delivery in the absence of traditional medical indications - and indeed, a simple pro- or con- position is never going to do justice to the subtlety of the issue. The right question is not whether women ought to be allowed to choose their delivery approach, but rather, taking the value of women’s autonomy in decision-making around birth as a given, what sorts of guidelines, practices, and social conditions will best promote and protect women’s full inclusion in a safe and positive birth process.

    We compared the prevalence of obesity based on both waist circumference for height and body mass index (BMI) in Iranian children and adolescents. Data on 13 120 children with a mean age of 12.45 ± 3.36 years (50.8% male) from the fourth Childhood and Adolescence Surveillance and Prevention of Adult Non-communicable Disease study were included. Measured waist circumference values were modelled according to age, gender and height percentiles. The prevalence of obesity was estimated using the 90th percentiles for both unadjusted and height-adjusted waist circumferences and compared with the World Health Organization BMI cut-offs. They were analysed further for short, average and tall children. Waist circumference values increased steadily with age. For short and average height children, the prevalence of obesity was higher when height-adjusted waist circumference was used. For taller children, the prevalence of obesity using height-adjusted waist circumference and BMI was similar, but lower than the prevalence based on measurements unadjusted for height. Height-adjusted waist circumference and BMI identified different children as having obesity, with overlaps of 69.47% for boys and 68.42% for girls. Just using waist circumference underestimated obesity in some Iranian children and measurements should be adjusted for height. ©2016 Foundation Acta Paediatrica. Published by John Wiley & Sons Ltd.

    Nutritional guidelines involving the feeding of very low birth weight babies (VLBW) recommend addition of Human Milk Fortifiers to breast milk. Owing to financial constraints, it is a practice in low- and middle-income countries (LMIC) to add coconut oil to aid better weight gain. There are inadequate data on improvement of growth parameters with oral coconut oil supplementation of breast milk. In this randomized controlled trial, we measured growth parameters and body composition of 60 babies who received either breast milk with coconut oil or breast milk alone. Randomization was stratified according to intrauterine growth appropriate for gestational age (n = 30) and small for gestational age (n = 30). There was no difference in weight gain between the two groups. The weight gain velocity was 15 ± 3.6 and 14.4 ± 3.4 g/kg/day (p value = 0.49) in the breast milk alone and in the breast milk with coconut oil group, respectively. There was no difference in increase in head circumference and length. Triceps skinfold thickness (n = 56) was similar in both groups, but subscapular skinfold thickness was significantly more in the coconut oil group. Total body fat percentage did not differ between the groups (25.2 ± 4.3 vs. 25.5 ± 4.3%, p = 0.79). Oral supplementation of coconut oil along with breast milk did not increase growth parameters or result in change in body composition in very low birth weight (VLBW) babies.

    The number of very low birth weight (VLBW) births is increasing worldwide. Despite better care in recent years, they have a high incidence of delayed growth and development. There are no previous studies regarding the growth and development of these infants at Queen Sirikit National Institute of Child Health (QSNICH). To study growth and developmental outcome of VLBW infants, aged 18-24 months who were discharged from QSNICH. VLBW infants who were discharged from QSNICH during the year 2007 were recruited in the study. Patients with chromosomal abnormalities, major congenital anomalies, definite congenital infections and positive maternal anti-HIV tests were excluded. At the corrected age of 18-24 months, the parents were called upon to bring their infants for complete physical examination and developmental evaluation on 2 occasions, two months apart. There were 111 cases of VLBW infants who were discharged from QSNICH during the year 2007. Fifty-four patients were eligible for the present study. Thirty cases (55.56%) were contacted for the first examination. During this examination, there were 3 cases (10%) with low head circumference, 1 case (3.33%) with poor weight gain, 5 cases (16.67%) with visual defect, 1 case (3.33%) with moderately severe hearing loss, 1 case (3.33%) with cerebral palsy and 7 cases (23.33%) with delayed development. Twenty-one cases could be recalled for a second evaluation. Two of the 5 cases had delayed language development. There were no cases with hydrocephalous, blindness or profound hearing loss. VLBW infants at QSNICH had much better survival during recent years. Most of these survivors had normal growth and development. Those with delayed growth and development need aggressive intervention and long-term follow-up for enhancement of quality of their lives.

    2017-04-01

    To develop a complete, population-based system for ultrasound-based fetal size monitoring and birth-weight prediction for use in the second and third trimesters of pregnancy. Using 31 516 ultrasound examinations from a population-based Norwegian clinical database, we constructed fetal size charts for biparietal diameter, femur length and abdominal circumference from 24 to 42 weeks' gestation. A reference curve of median birth weight for gestational age was estimated using 45 037 birth weights. We determined how individual deviations from the expected ultrasound measures predicted individual percentage deviations from expected birth weight. The predictive quality was assessed by explained variance of birth weight and receiver-operating characteristics curves for prediction of small-for-gestational age. A curve for intrauterine estimated fetal weight was constructed. Charts were smoothed using the gamlss non-linear regression method. The population-based approach, using bias-free ultrasound gestational age, produces stable estimates of size-for-age and weight-for-age curves in the range 24-42 weeks' gestation. There is a close correspondence between percentage deviations and percentiles of birth weight by gestational age, making it easy to convert between the two. The variance of birth weight that can be 'explained' by ultrasound increases from 8% at 20 weeks up to 67% around term. Intrauterine estimated fetal weight is 0-106 g higher than median birth weight in the preterm period. The new population-based birth-weight prediction model provides a simple summary measure, the 'percentage birth-weight deviation', to be used for fetal size monitoring throughout the third trimester. Predictive quality of the model can be measured directly from the population data. The model computes both median observed birth weight and intrauterine estimated fetal weight.

    Purpose: To illustrate that the attenuation formula based on monochromatic radiation in homogeneous objects may be used for dose regulation in body computed tomography (CT) based on patient circumference and using a simple cloth measuring tape. Material and Methods: Based on the attenuation formula for monochromatic radiation, the following Microsoft Excel equation was derived: mAsx≅mAsn*EXP((0.693/HVT)*(φx-φn)/PI()), where mAsx (milliampere second) in a patient with circumference φx is calculated based on the nominal mAsn set for a reference patient with the circumference φn with regard to indication, scan protocol, and available CT scanner. The HVT≅half-value thickness (object thickness change in cm affecting mAs setting by a factor of 2) resulting in the least mAs difference compared with published studies investigating the mAs needed for constant image noise in abdominal CT phantoms at 80-140 kVp was evaluated. Clinically recommended HVT values were applied to 20 patients undergoing abdominal CT using 30 effective mAs and 94 cm circumference as nominal settings, and an HVT of 9 cm. Results: The object-sized dependent mAs for constant image noise at 80-140 kVp in 0-47 cm diameter abdominal phantoms (31-148 cm in circumference) differed, with few exceptions, by no more than 0% from those obtained with our formula using an HVT of 3.2-3.8 cm. An HVT of 9 cm in the patient study resulted in the same image noise-patient circumference relation as a phantom study using a 'clinically adapted mAs' resulting in an acceptable noise according to diagnostic requirements. Clinical experiences recommend an HVT of about 8 cm for abdominal CT and 2 cm in thoracic CT. Changing the kVp from 20 to 80,00, or 40 requires a mAs change roughly by factors of 4, 2, and 0.6, respectively, for constant image noise. Conclusion: Until fully automatic automatic exposure control systems have been introduced, applying the formula in a computer program provides the radiologist with an

    Paralysis of the common peroneal nerve is one of the relatively common nerve injuries related to the lithotomy position with the use of a knee-crutch/leg-holder system. Several risk factors have been implicated in lithotomy position-related common peroneal nerve paralysis during operation. In the present study, 21 young healthy volunteers participated in the investigation of the causes of the paralysis of the common peroneal nerve in the lithotomy position using a knee-crutch/leg-holder; Knee Crutch. We assessed the external pressure applied to the fibular head and medial regions using the Big-Mat pressure-distribution measurement system. Relationships between the peak contact pressure and physical characteristics, such as sex, height, weight, body mass index (BMI), and fibular head circumference, were analyzed. The peak contact pressure to the fibular head region was greater for males than for females. For all subjects, significant positive correlations were observed between the peak contact pressure to the fibular head region and weight, BMI, or fibular head circumference. However, there was no significant difference between the peak contact pressure to the fibular head region and height for any subjects. Moreover, there was no sex-related difference in the peak contact pressure to the fibular medial region, and no significant differences between the peak contact pressure to the fibular medial region and height, weight, BMI, or fibular head circumference. External pressure to the fibular head region is greater for males than for females using a knee-crutch/leg-holder system in the lithotomy position. In addition, the external pressure to the fibular head region, but not the fibular medial region, increases with increasing weight, BMI, and fibular head circumference. Therefore, these patient-related characteristics may contribute to the risk of developing lower-extremity neuropathy, leading to injury or ischemia of the common peroneal nerve.

    Background The frequency of planned out-of-hospital birth in the United States has increased in recent years. The value of studies assessing the perinatal risks of planned out-of-hospital birth versus hospital birth has been limited by cases in which transfer to a hospital is required and a birth that was initially planned as an out-of-hospital birth is misclassified as a hospital birth. Methods We performed a population-based, retrospective cohort study of all births that occurred in Oregon during 2012 and 2013 using data from newly revised Oregon birth certificates that allowed for the disaggregation of hospital births into the categories of planned in-hospital births and planned out-of-hospital births that took place in the hospital after a woman’s intrapartum transfer to the hospital. We assessed perinatal morbidity and mortality, maternal morbidity, and obstetrical procedures according to the planned birth setting (out of hospital vs. hospital). Results Planned out-of-hospital birth was associated with a higher rate of perinatal death than was planned in-hospital birth (3.9 vs. 1.8 deaths per 1000 deliveries, P = 0.003; odds ratio after adjustment for maternal characteristics and medical conditions, 2.43; 95% confidence interval [CI], 1.37 to 4.30; adjusted risk difference, 1.52 deaths per 1000 births; 95% CI, 0.51 to 2.54). The odds for neonatal seizure were higher and the odds for admission to a neonatal intensive care unit lower with planned out-of-hospital births than with planned in-hospital birth. Planned out-of-hospital birth was also strongly associated with unassisted vaginal delivery (93.8%, vs. 71.9% with planned in-hospital births; P<0.001) and with decreased odds for obstetrical procedures. Conclusions Perinatal mortality was higher with planned out-of-hospital birth than with planned in-hospital birth, but the absolute risk of death was low in both settings.

    2017-01-01

    Simple Summary Birth weight is a key factor for neonatal mortality and morbidity in most mammalian species. The great morphological variability in size, body weight and breed, as well as in skeletal and cranial conformation makes it challenging to define birth weight standards in dogs. A total of 3293 purebred pups were surveyed to study which maternal aspects can determine birth weight considering head and body shape, size, body weight and breed in bitches, as well as litter size and sex in pups. In our sample, multivariate analysis outcomes suggested that birth weight and litter size were directly proportional to maternal size. The maternal body shape influenced both birth weight and litter size, whereas the maternal head shape had impact only on birth weight. Sex differences in birth weight were found. Birth weight and litter size also varied among breeds. The results of the present study could have practical implications allowing one to identify pups in need of admission to intensive nursing care, as occurs in humans. A deeper knowledge of the factors that significantly influence birth weight could positively affect the canine breeding management helping to prevent and reduce neonatal mortality. Abstract Despite increasing professionalism in dog breeding, the physiological range of birth weight in this species remains unclear. Low birth weight can predispose to neonatal mortality and growth deficiencies in humans. To date, the influence of the morphotype on birth weight has never been studied in dogs. For this purpose, an Italian census of birth weight was collected from 3293 purebred pups based on maternal morphotype, size, body weight and breed, as well as on litter size and sex of pups. Multivariate analysis outcomes showed that birth weight (p < 0.001) and litter size (p < 0.05) increased with maternal size and body weight. Birth weight was also influenced by the maternal head and body shape, with brachycephalic and brachymorph dogs showing the heaviest and

    1993-01-01

    Based on structural average curves of distance, velocity and acceleration, an analysis of the longitudinally assessed growth of weight, arm and calf circumferences and skinfolds (biceps, triceps, suprailiac, subscapular) was undertaken. The data come from the first Zürich longitudinal growth study and represent a normal sample. In addition to a graphic analysis, timing, intensity and duration of the mid-growth spurt (MS) and of the pubertal spurt (PS) are quantified via descriptive parameters of growth. Mechanisms are different and more complex for these variables, in particular for skinfolds, compared to previously studied somatic variables, such as height. Skinfolds showed a rapid decline to a negative velocity minimum in the first year, recovering to a pre-PS fat spurt, earlier and more pronounced for central (suprailiac, subscapular) than for peripheral skinfolds (biceps, triceps). At age of peak height velocity a drop occurred, stronger for boys, followed by a post-PS spurt. A further analysis demonstrates that these ups and downs in skinfold velocity are mainly due to subjects with thick skinfolds. Weight and circumferences show a distinct MS, with sex-independent characteristics and a strong, sex-dependent PS. Weight and even more arm circumference are delayed compared to height in puberty.

    Full Text Available Abstract Background The relationship between early childhood television viewing and physical fitness in school age children has not been extensively studied using objective outcome measures. Methods Using a sample of 1314 children from the Québec Longitudinal Study of Child Development, we examine the association between parental reports of weekly hours of television viewing, assessed at 29 and 53 months of age, and direct measures of second grade muscular fitness using performances on the standing long jump test (SLJ and fourth grade waist circumference. Results Controlling for many potentially confounding child and family variables, each hour per week of television watched at 29 months corresponded to a .361 cm decrease in SLJ, 95% CI between -.576 and -.145. A one hour increase in average weekly television exposure from 29 to 53 months was associated with a further .285 cm reduction in SLJ test performance, 95% CI between -.436 and -.134 cm and corresponded to a .047 cm increase in waistline circumference, 95% CI between .001 and .094 cm. Interpretation Watching television excessively in early childhood, may eventually compromise muscular fitness and waist circumference in children as they approach pubertal age.

    2017-12-01

    Full Text Available Objectives: To determine the optimal cutoff value for neck circumference (NC that define overweight/obesity and assess its predictive potential for cardiometabolic risks (CMR among Saudi subjects. Methods: A cross sectional study of 785 adults recruited from a public health awareness campaign in Medina, Saudi Arabia during June 2015. Waist circumference (WC, NC, body mass index (BMI, blood pressure (BP, and random blood glucose (RBG were assessed, and the presence of CMR were collected by a questionnaire. Pearson’s correlation coefficients were used to evaluate the associations of NC with other anthropometric indices and CMR. The optimal cutoff value for NC to identify overweight/obesity was determined by receiver operating characteristic (ROC curves. Results: There were significant correlations between NC and BMI, weight, WC, age, RBG, and BP. The area under the curve for NC and WC in the ROC analysis was 0.86 for men and 0.77 for women, and NC ≥39.25 cm for men and ≥34.75 cm for women were the best cutoff levels for identifying subjects with central obesity with an 89% sensitivity and a 71% specificity for men and an 80% sensitivity and a 65% specificity for women. These cutoff levels for NC were associated with a significantly increased risk for diabetes, dyslipidemia, and hypertension. Conclusion: Neck circumference is positively correlated with BMI and WC, and can be used to identify overweight/obesity and predict CMR in Saudi individuals.

    Full Text Available BACKGROUND: Obesity, particularly in the upper part of body, is a major health problem. Because body mass index (BMI does not adequately describe regional adiposity, other indices of body fatness are being explored. OBJECTIVES: To determine if neck circumference is a valid measure of adiposity (fat distribution among group of Egyptian children. SUBJECTS AND METHODS: This is a cross sectional study, included 50 obese subjects, aged 7 - 12 years recruited from Endocrine, obesity and Metabolism Pediatric Unit at Children Hospital, Cairo University and 50 healthy children, age and sex matched. All children were subjected to blood pressure assessment (systolic SBP and diastolic DBP, and anthropometric assessment (body weight, height, neck circumference (NC, waist (WC and hip (HC circumferences, and skin fold thicknesses at three sites: biceps, triceps and sub scapular. BMI [weight (kg/height (m2] was calculated. RESULTS: In healthy females, significant associations were detected between NC and SBP, DBP and all anthropometric measurements. However, in healthy males NC was not significantly associated with BMI, SBP and DBP. In the obese group; both sexes; insignificant association was found between NC and SBP, DBP, BMI and skinfold thickness. CONCLUSION: NC is related to fat distribution among normal healthy female children. However, this relation disappears with increasing adiposity. The results do not support the use of NC as a useful screening tool for childhood obesity.

    The fetal weight estimation depends largely on the accuracy of abdominal circumference. The quality criteria are standardized to minimize variability and include visualization of the stomach. The objective of this study is to investigate the presence or absence of the stomach on the abdominal circumference for 3 different operators. We conducted re-reading of 204 ultrasound images in the second and third trimester of pregnancy, performed by three operators, at the maternity Port Royal in Paris in 2013. On these images, the presence of the stomach was sought and other quality criteria were verified. Among the 204 images, 166 included the stomach (81%). When studying for each of the three operators, there were 79%, 72% and 98% of the stomach into the abdominal circumference, a significant difference between operators (P=0.0029). Regarding the secondary criteria, the quality criteria found most often were the calipers and well placed ellipse (89%). According to the previous studies, the stomach seems to be a reference to search. Our study shows variability depending on the different operators. If a hierarchy of quality criteria is to be considered, the stomach does not seem to be the first criterion to search. Copyright © 2015 Elsevier Masson SAS. All rights reserved.

    Cellulite is a frequent skin condition for which treatment remains a challenge. A wide variety of treatments are available but most procedures offer suboptimal clinical effect and/or delayed therapeutic outcome. Only few therapeutic options have proven efficacy in the treatment of cellulite. To determine the efficacy and the safety profiles of radiofrequency and dynamic muscle activation technology in treatment of abdominal cellulite and circumference reduction. Twenty-five females with abdominal cellulite received 6 weekly radiofrequency and dynamic muscle activation treatments. Treatment areas included the abdomen and both sides of flanks. Subjects were evaluated using standardized photographs, and measurements of body weight and abdominal circumference at baseline, before every treatment visit, and 1 week and four weeks after the final treatment. Subcutaneous tissue thickness was recorded by ultrasound at baseline and 4 weeks after completion of treatment protocol. Physicians' evaluation and patient's satisfaction of clinical improvement were also measured. All subjects completed the treatment protocol and attended every follow-up visits. There was significant abdominal circumference reduction of 2.96 and 2.52 cm at 1-, and 4-week follow-up visits (p cellulite appearance. The benefit of muscle activation is yet to be determined.

    Full Text Available Background. Neck circumference (NC is an anthropometric measure of obesity for upper subcutaneous adipose tissue distribution which is associated with cardiometabolic risk. This study investigated whether NC is associated with indicators of chronic kidney disease (CKD for high cardiometabolic risk patients. Methods. A total of 177 consecutive patients who underwent the outpatient departments of cardiology were prospectively enrolled in the study. The patients were aged >20 years with normal renal function or with stages 1–4 CKD. A linear regression was performed using the Enter method to present an unadjusted R2, standardized coefficients, and standard error, and the Durbin-Watson test was used to assess residual independence. Results. Most anthropometric measurements from patients aged ≧65 were lower than those from patients aged <65, except for women’s waist circumference (WC and waist hip ratio. Female NC obtained the highest R2 values for 24 hr CCR, uric acid, microalbuminuria, hsCRP, triglycerides, and HDL compared to BMI, WC, and hip circumference. The significances of female NC with 24 hr CCR and uric acid were improved after adjusted age and serum creatinine. Conclusions. NC is associated with indicators of CKD for high cardiometabolic risk patients and can be routinely measured as easy as WC in the future.

    Birth defects are a global public health problem because of their large contribution to infant mortalities and disabilities. It is estimated that 4%-6% of Chinese newborns are affected by birth defects every year. Surveillance is a basic approach to understanding the occurrence and associated factors of birth defects. The Ministry of Health of China initiated a national hospital-based birth defects monitoring system 20 years ago. Nearly every province in this country has established its own surveillance system in the past. The authors reviewed the result of the monitoring system at different administrative levels in China. Available publications on the surveillance of birth defects and data from national and provincial birth defects surveillance systems were reviewed to evaluate the effectiveness of the surveillance systems. According to the 2009 data, the national hospital-based birth defects surveillance system monitored over 1.3 million births, which accounted for more than 8% of births in China. In addition, 30 provincial hospital-based surveillance programs covered a birth population of more than 3.6 million (22% of births in China). Great achievements have been made in terms of case ascertainment, data quality control, and online reporting. But the surveillance systems in China still have some limitations. A short ascertainment period may miss some internal anomalies, inherited metabolic diseases, and malformed fetus aborted before the 28th gestational week. Discrepancies in antenatal or postnatal diagnosis of birth defects between surveillance institutes may affect the detection rate and introduce biases. Absence of baseline data and lack of integrated database systems limit the application of surveillance data to etiological studies and affect the process of decision-making. The surveillance system for birth defects is prerequisite to propose, conduct and assess any interventions for the disease. To meet the need of study and prevention of birth defects

    Naltrexone may provide a suitable alternative to methadone and buprenorphine in the treatment of pregnant opioid-dependent women; however, little is known about its effects on neonatal morbidity and mortality. The aim was to evaluate the health of neonates exposed to naltrexone in utero, and compare it with outcomes in neonates exposed to methadone or buprenorphine and a non-exposed control group. Sequential cohorts of Western Australian (WA) opioid-dependent women treated with implant naltrexone, oral methadone or sublingual buprenorphine were identified via records from a drug and alcohol clinic (Subiaco, WA) for naltrexone and state prescribing records for methadone and buprenorphine. A control cohort of non-opioid-dependent women was obtained from the WA electoral roll. Identifying information and treatment records for these women were linked against the Midwife Notification System records to identify exposed offspring born between 2001 and 2011. Birth characteristics, congenital anomalies and perinatal mortality for all neonates were extracted from state records. The birth characteristics of naltrexone-exposed neonates (n = 68) were superior to methadone-exposed neonates (n = 199) in terms of birth size (birth weight, head circumference and length), hospital length of stay (5.5 vs. 11.3 days), and rates of neonatal abstinence syndrome (NAS) (7.5 vs. 51.5%). Naltrexone-exposed neonates were generally not significantly different to buprenorphine-exposed neonates (n = 124), with the exception of significantly lower rates of NAS (7.5 vs. 41.8%) and shorter hospital length of stay (5.5 vs. 8.0 days) in naltrexone-exposed neonates. Compared with the control group of neonates (n = 569), naltrexone-exposed neonates were not significantly different in terms of overall rates of congenital anomalies, stillbirths and neonatal mortality; however, they were significantly smaller (3137.1 vs. 3378.0 g), spent more time in hospital following birth (5.5 vs. 4.3

    Full Text Available This study examines the scale unique instruments used for astronomical observation during the Joseon dynasty. The Small Simplified Armillary Sphere (小簡儀, So-ganui and the Sun-and-Stars Time-Determining Instrument (日星定時儀, Ilseong-jeongsi-ui are minimized astronomical instruments, which can be characterized, respectively, as an observational instrument and a clock, and were influenced by the Simplified Armilla (簡儀, Jianyi of the Yuan dynasty. These two instruments were equipped with several rings, and the rings of one were similar both in size and in scale to those of the other. Using the classic method of drawing the scale on the circumference of a ring, we analyze the scales of the Small Simplified Armillary Sphere and the Sun-and-Stars Time-Determining Instrument. Like the scale feature of the Simplified Armilla, we find that these two instruments selected the specific circumference which can be drawn by two kinds of scales. If Joseon’s astronomical instruments is applied by the dual scale drawing on one circumference, we suggest that 3.14 was used as the ratio of the circumference of circle, not 3 like China, when the ring’s size was calculated in that time. From the size of Hundred-interval disk of the extant Simplified Sundial in Korea, we make a conclusion that the three rings’ diameter of the Sun-and-Stars Time-Determining Instrument described in the Sejiong Sillok (世宗實錄, Veritable Records of the King Sejong refers to that of the middle circle of every ring, not the outer circle. As analyzing the degree of 28 lunar lodges (lunar mansions in the equator written by Chiljeongsan-naepyeon (七政算內篇, the Inner Volume of Calculation of the Motions of the Seven Celestial Determinants, we also obtain the result that the scale of the Celestial-circumference-degree in the Small Simplified Armillary Sphere was made with a scale error about 0.1 du in root mean square (RMS.

    Full Text Available Abstract Background Youth with diabetes are at increased risk for obesity and cardiovascular disease complications. However, less is known about the influence of built food environment on health outcomes in this population. The aim of this study was to explore the associations of accessibility and availability of supermarkets and fast food outlets with Body Mass Index (BMI z-score and waist circumference among youth with diabetes. Methods Information on residential location and adiposity measures (BMI z-score and waist circumference for 845 youths with diabetes residing in South Carolina was obtained from the South Carolina site of the SEARCH for Diabetes in Youth study. Food outlets data obtained from the South Carolina Department of Health and Environmental Control and InfoUSA were merged based on names and addresses of the outlets. The comprehensive data on franchised supermarket and fast food outlets was then used to construct three accessibility and availability measures around each youth’s residence. Results Increased number and density of chain supermarkets around residence location were associated with lower BMI z-score and waist circumference among youth with diabetes. For instance, for a female child of 10 years of age with height of 54.2 inches and weight of 70.4 pounds, lower supermarket density around residence location was associated with about 2.8–3.2 pounds higher weight, when compared to female child of same age, height and weight with highest supermarket density around residence location. Similarly, lower supermarket density around residence location was associated with a 3.5–3.7 centimeter higher waist circumference, when compared to residence location with the highest supermarket density. The associations of number and density of chain fast food outlets with adiposity measures, however, were not significant. No significant associations were observed between distance to the nearest supermarket and adiposity measures

    Cardiovascular risk factors (CVRFs) and impulsivity are common in bipolar disorder (BD), and CVRFs are also linked with impulsivity through a number of mechanisms, both behavioral and biological. This study examines the association between CVRFs and impulsivity in adolescents with BD. Subjects were 34 adolescents with BD and 35 healthy control (HC) adolescents. CVRFs were based on International Diabetes Federation metabolic syndrome criteria (triglycerides, high-density lipoprotein cholesterol, waist circumference, blood pressure (BP) and glucose). Impulsivity was measured using the computerized Cambridge Gambling Task (CGT). Analyses controlled for age, IQ, lifetime attention deficit hyperactivity disorder, and current antipsychotic use. Adolescents with BD had higher diastolic BP (73.36 ± 9.57 mmHg vs. 67.91 ± 8.74 mmHg, U = 401.0, p = 0.03), higher triglycerides (1.13 ± 0.60 mmol/L vs. 0.78 ± 0.38 mmol/L, U = 373.5, p = 0.008), and were more likely to meet high-risk criteria for waist circumference (17.6% vs. 2.9%, p = 0.04) vs. HC. Within the BD group, CGT sub-scores were correlated with CVRFs. For example, overall proportion bet was positively correlated with systolic (r = 0.387, p = 0.026) and diastolic (ρ = 0.404, p = 0.020) BP. Quality of decision-making was negatively correlated with systolic BP (ρ = -0.401, p = 0.021) and waist circumference (ρ = -0.534, p = 0.003). Significant interactions were observed, such that BD diagnosis moderates the relationship between both waist circumference and BP with CGT sub-scores. BP and waist circumference are associated with impulsivity in BD adolescents, but not in HC adolescents. Future studies are warranted to determine temporality and to evaluate whether optimizing CVRFs improves impulsivity among BD adolescents. Copyright © 2016 Elsevier Ltd. All rights reserved.

    Epicardial fat is an upper body visceral fat depot that may play a significant role in the development of adverse metabolic and cardiovascular risk profiles. There is a significant direct relationship between the amount of epicardial fat and general body adiposity (body mass index, BMI), but data regarding subcutaneous adiposity is limited. We conducted a study to determine the association between neck circumference and epicardial fat thickness in healthy young male individuals, and assess their individual correlations with general body adiposity and cardiometabolic risk factors. One hundred consecutive male patients aged 18 years or older with no known major medical conditions were included in the study. All participants underwent detailed physical examination including measurement of blood pressure, weight, height, waist/hip ratio, and neck circumference. Blood was collected to determine fasting glucose and lipid parameters. A standard echocardiographic examination was performed with additional epicardial fat thickness determination. Among 100 study participants, neck circumference correlated significantly with weight, waist circumference, BMI, blood glucose, serum total cholesterol, low-density (LDL)-cholesterol, and triglycerides levels. No significant correlation was found between neck circumference and high-density lipoprotein (HDL)-cholesterol levels. Neck circumference correlated moderately and positively with echocardiographic epicardial fat thickness. Among patients with low cardiometabolic risk, increased neck circumference was associated with increased epicardial fat thickness. A gordura epicárdica é um depósito de gordura visceral na parte superior do organismo que pode desempenhar um papel importante no desenvolvimento de perfis cardiovasculares e metabólicos adversos. Há uma relação direta significativa entre a quantidade de gordura epicárdica e a adiposidade corporal geral (índice de massa corporal, IMC), mas dados sobre a adiposidade

    Soccer is currently the most popular and fastest growing sport worldwide, with approximately 265 million registered soccer players existing around the world. The popularity of the sport, coupled with the high incidence of 18.8-21.5 head injuries per 1,000 player hours reported, make it essential that clinicians, coaches, and the athletes, have a solid understanding of head injuries. The successful rehabilitation of athletes with head injuries relies upon early and accurate identification strategies and implementation of appropriate return to play measures across all areas in the continuum of care. Soccer is a frequently played sport, and head injuries are common. Therefore, it is imperative that clinicians, coaches, and the athletes themselves have a solid understanding of head injury prevention, diagnosis, and treatment options. The purpose of this article was to provide rehabilitation nurses with current information regarding frequently occurring head injuries in the widespread sport of soccer. © 2015 Association of Rehabilitation Nurses.

    Direct intervention in infant delivery by non-parturient individuals is a rare phenomenon in nonhuman primates. In contrast, birth assistance by other individuals, or the practice of midwifery, is universal among human societies and generally believed to be a behavior unique to our species. It has been proposed that the enlarged head of the human fetus and the relatively narrow birth canal constrained by bipedalism has made human parturition more difficult than in nonhuman primates, and these anatomic challenges have led to the rotation of the fetus in the birth canal and an occiput anterior (i.e., backward-facing) orientation of emergence. These characteristics have hindered the mother's ability to self-assist the delivery of the infant, therefore necessitating assistance by other individuals or midwives for successful birth. Here we report the first high-definition video recordings of birth intervention behavior in a wild nonhuman primate, the white-headed langur (Trachypithecus leucocephalus). We observed that while a primiparous female gave birth to an infant in an occiput posterior (i.e., forward-facing) orientation, a multiparous female intervened in the delivery by manually pulling the infant out of the birth canal and cared for it in the following hours. Our finding shows extensive social interactions throughout parturition, and presents an unequivocal case of non-maternal intervention with infant birth in a nonhuman primate.

    To evaluate the possibility of using maternal anthropometric measurements for prediction of low birth weight in developing and developed countries. Bivariate diagnostic meta-analysis was performed with hierarchical summary receiver operating characteristic curves. Ten databases, i.e., PubMed, EMBASE, CINAHL, PsycINFO, Wiley InterScience, ProQuest Health and Medical Complete™, ProQuest Dissertations and Theses Database, the entire Cochrane Library (e.g., CENTRAL), Google Scholar, and Scopus were searched. The references and PubMed-related citations of potentially eligible articles and reviews were also investigated. With regard to maternal height, weight, arm circumference, abdominal circumference, body mass index (BMI), and weight gain, 111, 126, 25, 4, 131, and 59 studies extracted from 49, 38, 12, 1, 50, and 23 data sources, respectively, were finally included in the analysis. The sensitivity [=0.46, 95 % confidence interval (CI) 0.35-0.52 to 0.64, 95 % CI 0.56-0.71], specificity (=0.46, 95 % CI 0.38-0.54 to 0.72, 95 % CI 0.64-0.79) and diagnostic odds ratios (=2, 95 % CI 1-2 to 3, 95 % CI 3-4) for maternal height, weight, arm circumferences, BMI, and weight gain were low and 95 % confidence and prediction regions were too large for practical use. The findings for abdominal circumference were not generalizable because only one data source was available. There is no evidence that maternal anthropometric measurements are good predictors of low birth weight.

    Previous studies have produced conflicting results with regard to the association between birth weight and developmental stuttering. This study sought to determine whether birth weight was associated with childhood and/or adolescent stuttering in three British birth cohort samples. Logistic regression analyses were carried out on data from the Millenium Cohort Study (MCS), British Cohort Study (BCS70) and National Child Development Study (NCDS), whose initial cohorts comprised over 56,000 individuals. The outcome variables were parent-reported stuttering in childhood or in adolescence; the predictors, based on prior research, were birth weight, sex, multiple birth status, vocabulary score and mother's level of education. Birth weight was analysed both as a categorical variable (low birth weight, stuttering during childhood (age 3, 5 and 7 and MCS, BCS70 and NCDS, respectively) or at age 16, when developmental stuttering is likely to be persistent. None of the multivariate analyses revealed an association between birth weight and parent-reported stuttering. Sex was a significant predictor of stuttering in all the analyses, with males 1.6-3.6 times more likely than females to stutter. Our results suggest that birth weight is not a clinically useful predictor of childhood or persistent stuttering. Copyright © 2013 Elsevier Inc. All rights reserved.

    BACKGROUND: Waist circumference threshold values used in sub-Saharan Africa correspond to those of European populations and are therefore inappropriate. Thus, they may over predict insulin resistance, especially in hypertensive Africans, in whom there is often no association between blood pressure and insulin resistance. Using bioelectrical impedance measurement in sub-Saharan Africa could possibly be advantageous to overcome the shortcomings of waist circumference measurement. The aim of thi...

    Full Text Available Previous studies have indicated that neck circumference is a valuable predictor for obesity and metabolic syndrome, but little evidence is available for fatty liver disease. We examined the association of neck circumference with fatty liver disease and evaluated its predictive value in Chinese adults.This cross-sectional study comprised 4053 participants (1617 women and 2436 men, aged 20-88 recruited from the Health Examination Center in Guangzhou, China between May 2009 and April 2010. Anthropometric measurements were taken, abdominal ultrasonography was conducted and blood biochemical parameters were measured. Covariance, logistic regression and receiver operating characteristic curve analyses were employed.The mean neck circumference was greater in subjects with fatty liver disease than those without the disease in both women and men after adjusting for age (P<0.001. Logistic regression analysis showed that the age-adjusted ORs (95% CI of fatty liver disease for quartile 4 (vs. quartile 1 of neck circumference were 7.70 (4.95-11.99 for women and 12.42 (9.22-16.74 for men. After further adjusting for other anthropometric indices, both individually and combined, the corresponding ORs remained significant (all P-trends<0.05 but were attenuated to 1.94-2.53 for women and 1.45-2.08 for men. An additive interaction existed between neck circumference and the other anthropometric measures (all P<0.05. A high neck circumference value was associated with a much greater prevalence of fatty liver disease in participants with both high and normal BMI, waist circumference and waist-to-hip ratio values.Neck circumference was an independent predictor for fatty liver disease and provided an additional contribution when applied with other anthropometric measures.

    Full Text Available Neck circumference (NC is an anthropometric measurement of differentiating body fat distributions and a marker of upper subcutaneous adiposity. The present study highlights the association and importance of NC as a suitable proxy screening measure of overweight/obesity as compared to the conventional anthropometric variables used among Indian adults. The present community based cross-sectional study was undertaken among 1169 Karbi adults (males: 625; females: 544 residing in Karbi Anglong district of Assam, Northeast India, who were selected through a multistage stratified random sampling method. Height, weight, waist circumference (WC, hip circumference (HC and NC were recorded using standard procedures. The body mass index (BMI was calculated and prevalence of overweight/obesity was assessed using standard cut-offs. The prevalence of obesity using BMI (≥25.00 kg m-2 was 15.52% and 15.26% among males and females, respectively (p≥0.05.The prevalence of obesity using NC was observed to be significantly higher among males (48.80% than females (19.12% (p<0.01. The binary logistic regression analysis showed that NC predicted obesity over the conventional anthropometric variables with reasonable accuracy (p<0.01. The ROC-AUC analysis showed a relatively greater significant association between BMI, WC and HC and NC for obesity (p<0.01. Thus, NC appears to be a potentially simple, easyto- use screening measure for predicting obesity among adults. Further studies are required to validate its use for screening of obesity among other ethnic populations in India.

    Full Text Available BACKGROUND: Central obesity is associated with various chronic metabolic disorders characterized by abnormal cytokine production, increased acute phase reactants, and activation of inflammatory signaling pathways. This study was aimed to investigate the association of waist circumference, chemerin, and retinol binding protein (RBP-4 with inflammation in men with central obesity. METHODS: The research was conducted with a crosssectional design involving 68 centrally obese male subjects aged 30 to 60 years old, with waist circumference (WC >90 cm. All subjects fulfilled the inclusion and exclusion criteria. Anthropometric parameters, fasting glucose, creatinine, SGOT, SGPT, and hsCRP were measured. Serum concentrations of chemerin and RBP4 were measured by ELISA. RESULTS: The trend lines showed that chemerin, RBP4 and hsCRP increased with WC. Pearson correlation test showed a positively significant correlation between WC and hsCRP (r=0.242, p<0.05; and also between chemerin and hsCRP (r=0.244, p<0.05 and RBP4 (r=0.321, p<0.01. Subjects were stratified into four groups based on their chemerin and RBP4 levels (high chemerin/high RBP4, high chemerin/low RBP4, low chemerin/high RBP4, or low chemerin/low RBP4. Subjects who were in the high chemerin/low RBP4 group were more likely to have high level of inflammation (47.6%, but subjects with high chemerin/high RBP4 showed low level of inflammation (42.9% as compared with the other three groups. CONCLUSIONS: We concluded that increased WC was correlated with elevated levels of chemerin, RBP4 and hsCRP. High chemerin was correlated with increased level of RBP4 as well as with high level of inflammation. KEYWORDS: waist circumference, chemerin, RBP4, hsCRP, inflammation.

    To validate the use of waist circumference to assess reversal of insulin resistance after weight loss induced by bariatric surgery. In cross-sectional studies, threshold values for insulin resistance were determined with homeostasis model assessment of insulin resistance (HOMA-IR) (algorithm based on fasting plasma glucose and insulin) in 1018 lean subjects and by hyperinsulinemic euglycemic clamp (clamp) in 26 lean women. In a cohort study on 211 patients scheduled for bariatric surgery, HOMA-IR and waist circumference were measured before and 1.5-3 years after weight reduction. In a subgroup of 53 women, insulin sensitivity was also measured using clamp. The threshold for insulin resistance (90th percentile) was 2.21 (mg dl(-1) fasting glucose × mU l(-1) fasting insulin divided by 405) for HOMA-IR and 6.118 (mg glucose per kg body weight per minute) for clamp. Two methods to assess reversal of insulin resistance by measuring waist circumference were used. A single cutoff value to HOMA-IR analyses. Reversal of insulin resistance could either be assessed by a diagram based on initial waist circumference and reduction of waist circumference, or by using 100 cm as a single cutoff for waist circumference after weight reduction induced by bariatric surgery.

    The relationship between metabolic risk and time spent sitting, standing and stepping has not been well established. The present study aimed to determine associations of objectively measured time spent siting, standing and stepping, with coronary heart disease (CHD) risk. A cross-sectional study of healthy non-smoking Glasgow postal workers, n=111 (55 office workers, 5 women, and 56 walking/delivery workers, 10 women), who wore activPAL physical activity monitors for 7 days. Cardiovascular risks were assessed by metabolic syndrome categorisation and 10-year PROCAM (prospective cardiovascular Munster) risk. Mean (s.d.) age was 40 (8) years, body mass index 26.9 (3.9) kg m -2 and waist circumference 95.4 (11.9) cm. Mean (s.d.) high-density lipoprotein cholesterol (HDL cholesterol) 1.33 (0.31), low-density lipoprotein cholesterol 3.11 (0.87), triglycerides 1.23 (0.64) mmol l -1 and 10-year PROCAM risk 1.8 (1.7)%. The participants spent mean (s.d.) 9.1 (1.8) h per day sedentary, 7.6 (1.2) h per day sleeping, 3.9 (1.1) h per day standing and 3.3 (0.9) h per day stepping, accumulating 14 708 (4984) steps per day in 61 (25) sit-to-stand transitions per day. In univariate regressions-adjusting for age, sex, family history of CHD, shift worked, job type and socioeconomic status-waist circumference (P=0.005), fasting triglycerides (P=0.002), HDL cholesterol (P=0.001) and PROCAM risk (P=0.047) were detrimentally associated with sedentary time. These associations remained significant after further adjustment for sleep, standing and stepping in stepwise regression models. However, after further adjustment for waist circumference, the associations were not significant. Compared with those without the metabolic syndrome, participants with the metabolic syndrome were significantly less active-fewer steps, shorter stepping duration and longer time sitting. Those with no metabolic syndrome features walked >15 000 steps per day or spent >7 h per day upright

Studies in the English language published between January 2005 and August 2013 were examined. Subjects were infants born at ≤32 weeks of gestation. Main outcome measures included head growth, neurodevelopmental outcomes, and correlation between head size and neuroimaging.Results: Thirty-four articles comprising 9,394 infants met inclusion/exclusion criteria. Of these, 31 studies (6,592 subjects report head growth data measured at two or more time points. Neurodevelopmental outcome at ≥2 years was reported by eleven studies (3,817 subjects. Nine studies (2,363 subjects included neuroimaging data. Catch-up head growth was found to occur in the first year after birth. Poor nutrition was linked with poorer head growth. Small head size was associated with poor psychomotor and mental skills, higher rates of cerebral palsy, and autism. However, suboptimal head size at birth was not predictive of poor outcome, unless it persisted. Head size appears to correlate with brain volume at term. Associations between white matter abnormalities have been found by ultrasonography. In contrast, in magnetic resonance imaging (MRI studies, gray matter seems to be the most susceptible to impairments during postnatal growth.Conclusion: Head growth in early neonatal life is of importance. Avoiding growth impairment during neonatal care may allow for optimal cortical development. Many factors impact upon early head growth, particularly appropriate nutrition. There is no

    The effects of large heads on stresses at the THA trunnion-head junction and their impact on tribocorrosion/metal ion release remain controversial. A 12/14 3D-model of a stem with different head sizes was investigated. Material properties of titanium were assigned to the trunnion and cobalt-chrome/alumina to the heads. A load simulating walking single-leg stand phase was applied to the head. A total contact head-trunnion interface was assumed. The area underneath the junction underwent significant elevations in stresses as head size increased from 28- to 40-mm. Maximum principal stress doubled between 28 and 40-mm heads, regardless of head material. Stress levels had a direct correlation to head diameter. Stress increases observed using increasingly larger heads will probably contribute to head-trunnion tribocorrosion and ion release. Copyright © 2015 Elsevier Inc. All rights reserved.

    An association between birth order and reduced unaided vision (a surrogate for myopia) has been observed previously. We examined the association between birth order and myopia directly in four subject groups. Subject groups were participants in (1) the Avon Longitudinal Study of Parents and Children (ALSPAC; UK; age 15 years; N = 4401), (2) the Singapore Cohort Study of Risk Factors for Myopia (SCORM; Singapore; age 13 years; N = 1959), (3) the Raine Eye Health Study (REHS; Australia; age 20 years; N = 1344), and (4) Israeli Defense Force Pre-recruitment Candidates (IDFC; Israel; age 16-22 years; N = 888,277). The main outcome was odds ratios (OR) for myopia in first-born versus non-first-born individuals after adjusting for potential risk factors. The prevalence of myopia was numerically higher in first-born versus non-first-born individuals in all study groups, but the strength of evidence varied widely. Adjusted ORs (95% confidence intervals, CIs) were: ALSPAC, 1.31 (1.05-1.64); SCORM, 1.25 (0.89-1.77); REHS, 1.18 (0.90-1.55); and IDFC, 1.04 (1.03-1.06). In the large IDFC sample, the effect size was greater (a) for the first-born versus fourth- or higher-born comparison than for the first-born versus second/third-born comparison (p 4000 participants provided strong statistical support for the association. The available evidence suggested the relationship was independent of established risk factors such as time outdoors/reading, and thus may arise through a different causal mechanism.

    Rates of advanced chronic kidney disease and renal replacement therapy are higher in South Asian than in white British populations. Low birth weight is also more frequent in South Asian populations and has been associated with increased risks of kidney disease, perhaps due to a reduced nephron endowment. Using ultrasound scans at 34 weeks of gestation, we measured fetal kidney dimensions (transverse and anteroposterior diameters, length and circumference) and derived volume in a random sample of 872 white British and 715 South Asian participants in the Born in Bradford cohort study. Kidney measurements were compared between ethnic groups. Birth weight for gestational age at 40 weeks was 200 g less in South Asian babies compared with white British babies. The mean kidney volume for gestational age was 16% lower in South Asian than in white British babies [8.79 versus 10.45 cm(3), difference 1.66 cm(3) (95% confidence interval 1.40-1.93, P < 0.001)]. The difference was robust after adjustment for maternal age, socio-economic factors, marital status, body mass index, smoking and alcohol use in pregnancy, parity, baby's gender and birth weight for gestational age [adjusted difference 1.38 cm(3) (0.97-1.84), P < 0.001]. There were smaller reductions in other fetal measures. South Asian babies have smaller kidneys compared with white British babies, even after adjusting for potential confounders including birth weight. This finding may contribute to increased risks of adult kidney disease in South Asian populations. © The Author 2015. Published by Oxford University Press on behalf of ERA-EDTA. All rights reserved.

    To determine whether calf circumference (CC), related to appendicular skeletal muscle mass, can be used as a measure of sarcopenia and is related to physical function. Retrospective analysis of data from 1992 to 1994 of the European Patient Information and Documentation Systems Study. Community setting in France. One thousand four hundred fifty-eight French women aged 70 and older without previous history of hip fracture were recruited from the electoral lists. Muscular mass was assessed using dual-energy x-ray absorptiometry (DEXA). CC was measured using a tape measure. Anthropometric measurements (height; weight; and waist, hip, and calf circumference), strength markers (grip strength), and self-reported physical function were also determined. Sarcopenia was defined (using DEXA) as appendicular skeletal muscle mass (weight (kg)/height (m2)) less than two standard deviations below the mean of a young female reference group. The prevalence of sarcopenia was 9.5%. CC was correlated with appendicular skeletal muscle mass (r = 0.63). CC under 31 cm was the best clinical indicator of sarcopenia (sensitivity = 44.3%, specificity = 91.4%). CC under 31 cm was associated with disability and self-reported physical function but not sarcopenia (defined using DEXA), independent of age, comorbidity, obesity, income, health behavior, and visual impairment. CC cannot be used to predict sarcopenia defined using DEXA but provides valuable information on muscle-related disability and physical function.

    The analysis of body composition through direct and indirect methods allows the study of the various components of the human body, becoming the central hub for assessing nutritional status. The objective of the study was to develop equations for predicting body fat% from circumferential body arm, waist and calf and propose percentiles to diagnose the nutritional status of school children of both sexes aged 4-10 years. We selected intentionally (non-probabilistic) 515 children, 261 children and 254 being girls belonging to Program interaction and development of children and adolescents from the State University of Campinas (Sao Paulo, Brazil). Anthropometric variables were evaluated for weight, height, triceps and subscapular skinfolds and body circumferences of arm, waist and calf, and the% fat determined by the equation proposed by Boileau, Lohman and Slaughter (1985). Through regression method 2 were generated equations to predict the percentage of fat from the body circumferences, the equations 1 and 2 were validated by cross validation method. The equations showed high predictive values ranging with a R² = 64-69%. In cross validation between the criterion and the regression equation proposed no significant difference (p > 0.05) and there was a high level of agreement to a 95% CI. It is concluded that the proposals are validated and shown as an alternative to assess the percentage of fat in school children of both sexes aged 4-10 years in the region of Campinas, SP (Brazil).

  20. Persistently High Hip Circumference after Bariatric Surgery Is a Major Hurdle to Successful Hip Replacement

    Directory of Open Access Journals (Sweden)

    Menachem M. Meller

    2014-01-01

    Full Text Available The prevalence of class III obesity (BMI≥40 kg/m2 in black women is 18%. As class III obesity leads to hip joint deterioration, black women frequently present for orthopedic care. Weight loss associated with bariatric surgery should lead to enhanced success of hip replacements. However, we present a case of a black woman who underwent Roux-en-Y gastric bypass with the expectation that weight loss would make her a better surgical candidate for hip replacement. Her gastric bypass was successful as her BMI declined from 52.0 kg/m2 to 33.7 kg/m2. However, her hip circumference after weight loss remained persistently high. Therefore, at surgery the soft tissue tunnel geometry presented major challenges. Tunnel depth and immobility of the soft tissue interfered with retractor placement, tissue reflection, and surgical access to the acetabulum. Therefore a traditional cup placement could not be achieved. Instead, a hemiarthroplasty was performed. After surgery her pain and reliance on external support decreased. But her functional independence never improved. This case demonstrates that a lower BMI after bariatric surgery may improve the metabolic profile and decrease anesthesia risk, but the success of total hip arthroplasties remains problematic if fat mass in the operative field (i.e., high hip circumference remains high.

    To examine the form of the relationship between sleep duration and anthropometric measures and possible differences in these relationships by gender and race or ethnicity. Data for 13,742 participants aged ≥20 years from the National Health and Nutrition Examination Survey 2005-2010 were used. Sleep duration was categorized as ≤6 (short sleepers), 7-9, and ≥10 hours (long sleepers). Short sleepers were as much as 1.7 kg/m² (SE 0.4) heavier and had 3.4 cm (SE 1.0) more girth than long sleepers. Among participants without depression or a diagnosed sleep disorder, sleep duration was significantly associated with body mass index (BMI) and waist circumference in an inverse linear association in the entire sample, men, women, whites, African Americans, and participants aged 20-39 years. No evidence for statistical interaction by gender and race or ethnicity was observed. Regression coefficients were notably stronger among adults aged 20-39 years. Compared to participants who reported sleeping 7-9 hours per night, short sleepers were more likely to be obese and have abdominal obesity. In this nationally representative sample of US adults, an inverse linear association most consistently characterized the association between sleep duration and BMI and waist circumference.

ELBW children performed consistently worse on neurocognitive testing with an average intelligence quotient equivalent at 11 years of 92.5 (SD 13.1. Catch-up growth was not associated with neurocognitive performance. Compared to controls, ELBW cases had lower grip strength (13.6 vs. 15.9 kg and percentage lean body weight (75.1 vs. 80.5%, but higher body fat (24.6 vs. 19.2% and advanced puberty scores at 11 years (all P≤0.025. Catch-up growth for weight and height in the first two years of life in cases was associated with a lower percentage body fat compared to cases without catch-up growth (16.8% catch-up growth for weight vs. 25.7%, P<0.001; 20.9% catch-up for height vs. 25.8%, P = 0.049.In young adolescence, former ELBW children still have difficulties to reach their target height. Compared to normal birth weight controls, ELBW adolescents show lower neurocognitive performance and grip strength and a higher percentage body fat, a potential risk factor for adverse health outcomes in adulthood. Our key finding is that catch-up growth in ELBW children in the first two years of life is associated with a lower percentage body fat and is therefore likely to be beneficial.

    Injuries to the head and neck are the most frequent catastrophic sports injury, and head injuries are the most common direct athletic cause of death. Although direct compressive forces may injure the brain, neural tissue is particularly susceptible to injury from shearing stresses, which are most likely to occur when rotational forces are applied to the head. The most common athletic head injury is concussion, which may very widely in severity. Intracranial haemorrhage is the leading cause of head injury death in sports, making rapid initial assessment and appropriate follow up mandatory after a head injury. Diffuse cerebral swelling is another serious condition that may be found in the child or adolescent athlete, and the second impact syndrome is a major concern in adult athletes. Many head injuries in athletes are the result of improper playing techniques and can be reduced by teaching proper skills and enforcing safety promoting rules. Improved conditioning (particularly of the neck), protective headgear, and careful medical supervision of athletes will also minimise this type of injury.

    To examine the relationship between calf circumference and muscle mass, and to evaluate the suitability of calf circumference as a surrogate marker of muscle mass for the diagnosis of sarcopenia among middle-aged and older Japanese men and women. A total of 526 adults aged 40-89 years participated in the present cross-sectional study. The maximum calf circumference was measured in a standing position. Appendicular skeletal muscle mass was measured using dual-energy X-ray absorptiometry, and the skeletal muscle index was calculated as appendicular skeletal muscle mass divided by the square of the height (kg/m(2)). The cut-off values for sarcopenia were defined as a skeletal muscle index of less than -2 standard deviations of the mean value for Japanese young adults, as defined previously. Calf circumference was positively correlated with appendicular skeletal muscle (r = 0.81 in men, r = 0.73 in women) and skeletal muscle index (r = 0.80 in men, r = 0.69 in women). In receiver operating characteristic analysis, the optimal calf circumference cut-off values for predicting sarcopenia were 34 cm (sensitivity 88%, specificity 91%) in men and 33 cm (sensitivity 76%, specificity 73%) in women. Calf circumference was positively correlated with appendicular skeletal muscle mass and skeletal muscle index, and could be used as a surrogate marker of muscle mass for diagnosing sarcopenia. The suggested cut-off values of calf circumference for predicting low muscle mass are <34 cm in men and <33 cm in women. © 2014 Japan Geriatrics Society.

  8. Reliability of knee joint range of motion and circumference measurements after total knee arthroplasty: does tester experience matter?

    Two of the most utilized outcome measures to assess knee joint range of motion (ROM) and intra-articular effusion are goniometry and circumference, respectively. Neither goniometry nor circumference of the knee joint have been examined for both intra-tester and inter-tester in patients with total knee arthroplasty (TKA). The purpose of this study was to determine the intra-tester and inter-tester reliability of active and passive knee joint ROM and circumference in patients with TKA when administered by physiotherapists (testers) with different clinical experience. The design was an intra-tester, inter-tester and intra-day reliability study. Nineteen outpatients (10 females) having received a TKA were examined by an inexperienced and an experienced physiotherapist. Following a standardized protocol, active and passive knee joint ROM and circumference measurements were obtained using a universal goniometer and a tape measure, respectively. To establish reliability, intraclass correlation coefficients (ICC(2,1)) and smallest real difference (SRD) were calculated. The knee joint ROM and circumference measurements were generally reliable (ICC > 0.8) within and between physiotherapists (except passive knee extension). Changes in knee joint ROM of more than 6.6 degrees and 10 degrees (except active knee flexion) and knee joint circumference of more than 1.0 cm and 1.63 cm represent a real clinical improvement (SRD) or deterioration for a single individual within and between physiotherapists, respectively. Generally, the experienced tester recorded larger knee joint ROM and lower circumference values than that of the inexperienced tester. In clinical practice, we suggest that repeated knee goniometric and circumferential measurements should be recorded by the same physiotherapist in individual patients with TKA. Tester experience appears not to influence the degree of reliability. (c) 2009 John Wiley & Sons, Ltd.

    MR imaging has been shown to be more sensitive and specific than planar scintigraphy for avascular necrosis (AVN) of the femoral head. However, experience with single photon emission CT (SPECT) is limited. The authors retrospectively compared 1.5-T MR imaging with SPECT in 14 patients with suspected femoral head AVN. Agreement between MR imaging and SPECT was present in 24 femurs, 14 normal and ten with AVN. MR imaging showed changes of AVN in the remaining four femoral heads. Of these, one was normal and the other three inconclusive for AVN by SPECT. The authors conclude that MR imaging is superior to SPECT for the evaluation of AVN of the hip

    To examine the prospective association of television (TV) watching from adolescence to young adulthood with BMI, waist circumference (WC), waist-to-hip ratio (WHR) and obesity. A community-based longitudinal cohort study. Mater-University of Queensland Study of Pregnancy (MUSP) Cohort, Brisbane, Australia. A sub-sample of 2439 children was followed up at ages 14 years and 21 years as part of a population-based birth cohort. Offspring reported the number of TV viewing hours each day at 14 and 21 years. BMI, WC and WHR were measured at 21 years. In the adjusted model, offspring who watched TV for adolescence into young adulthood were at less risk of becoming obese and those who continued or increased their TV watching to ≥ 3 h/d were at greater risk of becoming obese. This association remained independent of the potential confounding factors considered. The present findings suggest that our efforts to decrease obesity by reducing TV watching hours among adults should consider interventions to reduce TV time among adolescents.

  8. Single camera multi-view anthropometric measurement of human height and mid-upper arm circumference using linear regression.

    Manually measured anthropometric quantities are used in many applications including human malnutrition assessment. Training is required to collect anthropometric measurements manually, which is not ideal in resource-constrained environments. Photogrammetric methods have been gaining attention in recent years, due to the availability and affordability of digital cameras. The primary goal is to demonstrate that height and mid-upper arm circumference (MUAC)-indicators of malnutrition-can be accurately estimated by applying linear regression to distance measurements from photographs of participants taken from five views, and determine the optimal view combinations. A secondary goal is to observe the effect on estimate error of two approaches which reduce complexity of the setup, computational requirements and the expertise required of the observer. Thirty-one participants (11 female, 20 male; 18-37 years) were photographed from five views. Distances were computed using both camera calibration and reference object techniques from manually annotated photos. To estimate height, linear regression was applied to the distances between the top of the participants head and the floor, as well as the height of a bounding box enclosing the participant's silhouette which eliminates the need to identify the floor. To estimate MUAC, linear regression was applied to the mid-upper arm width. Estimates were computed for all view combinations and performance was compared to other photogrammetric methods from the literature-linear distance method for height, and shape models for MUAC. The mean absolute difference (MAD) between the linear regression estimates and manual measurements were smaller compared to other methods. For the optimal view combinations (smallest MAD), the technical error of measurement and coefficient of reliability also indicate the linear regression methods are more reliable. The optimal view combination was the front and side views. When estimating height by linear

  9. Comparison of body mass index, waist circumference, and waist/hip ratio in predicting incident diabetes: a meta-analysis.

    Body mass index, waist circumference, and waist/hip ratio have been shown to be associated with type 2 diabetes. From the clinical perspective, central obesity (approximated by waist circumference or waist/hip ratio) is known to generate diabetogenic substances and should therefore be more informative than general obesity (body mass index). Because of their high correlation, from the statistical perspective, body mass index and waist circumference are unlikely to yield different answers. To compare associations of diabetes incidence with general and central obesity indicators, the authors conducted a meta-analysis based on published studies from 1966 to 2004 retrieved from a PubMed search. The analysis was performed with 32 studies out of 432 publications initially identified. Measures of association were transformed to log relative risks per standard deviation (pooled across all studies) increase in the obesity indicator and pooled using random effects models. The pooled relative risks for incident diabetes were 1.87 (95% confidence interval (CI): 1.67, 2.10), 1.87 (95% CI: 1.58, 2.20), and 1.88 (95% CI: 1.61, 2.19) per standard deviation of body mass index, waist circumference, and waist/hip ratio, respectively, demonstrating that these three obesity indicators have similar associations with incident diabetes. Although the clinical perspective focusing on central obesity is appealing, further research is needed to determine the usefulness of waist circumference or waist/hip ratio over body mass index.

    Many observations of ball lightning report a ball of light, about 10 cm in diameter, moving at about walking speed, lasting up to 20 s and frequently existing inside of houses and even aeroplanes. The present paper reports detailed observations of the initiation or birth of ball lightning. In two cases, navigation crew of aircraft saw ball lightning form at the windscreen inside the cockpit of their planes. In the first case, the ball lightning occurred during a thunderstorm, with much lightning activity outside of the plane. In the second case, large "horns" of electrical corona were seen outside of the plane at the surface of the radome, just prior to the formation of the ball lightning. A third case reports ball lightning formed inside of a house, during a thunderstorm, at a closed glass window. It is proposed, based on two-dimensional calculations of electron and ion transport, that ball lightning in these cases is driven and formed by atmospheric ions impinging and collecting on the insulating surface of the glass or Perspex windows. This surface charge can produce electric fields inside of the cockpit or room sufficient to sustain an electric discharge. Charges of opposite sign to those outside of the window accumulate on the inside surface of the glass, leaving a ball of net charge moving inside of the cockpit or room to produce a pulsed discharge on a microsecond time scale.

    Full Text Available Background. Low birth weight is the single most important factor that determines the chances of child survival. A recent annual estimation indicated that nearly 8 million infants are born with low birth weight in India. The infant mortality rate is about 20 times greater for all low birth weight babies. Methods. A matched case–control study was conducted on 130 low birth weight babies and 130 controls for 12 months (from August 1, 2007, to July 31, 2008 at the Central Referral Hospital, Tadong, East District of Sikkim, India. Data were analyzed using the Statistical Package for Social Sciences, version 10.0 for Windows. Chi-square test and multiple logistic regression were applied. A P value less than .05 was considered as significant. Results. In the first phase of this study, 711 newborn babies, borne by 680 mothers, were screened at the Central Referral Hospital of Sikkim during the 1-year study period, and the proportion of low birth weight babies was determined to be 130 (18.3%. Conclusion. Multiple logistic regression analysis, conducted in the second phase, revealed that low or middle socioeconomic status, maternal underweight, twin pregnancy, previous history of delivery of low birth weight babies, smoking and consumption of alcohol during pregnancy, and congenital anomalies had independent significant association with low birth weight in this study population.

    To investigate relationship between overactive bladder (OAB) and metabolic syndrome (MtS) by using neck circumference (NC). In retrospective view of prospective collected data, 204 women with or without OAB were enrolled into study, between August 2012 and December 2013. All patients were administered OAB validated questionnaires (OAB-V8) and whose score was > 8 were accepted as OAB. Patients were divided into two groups and group 1 consisted of patients with OAB, group 2 consisted of patients without OAB. Demographic data with anthropometric measurements and blood analyses were recorded. Statistical analyses including receiver operating characteristic (ROC) curves were performed; statistically significant p was syndrome seems like more common in women than in those without. NC may be a novel indicator for OAB in selected female patients with MtS.

    The objective of this study is are to examine the association of preadolescent obesity using body mass index (BMI) and waist circumference (WC) with health-related physical fitness components. Grades 4 to 6 students in 2 private schools in Manila were included in this study. Height, weight, WC, and BMI were obtained. Physical fitness field tests were sit-and-reach test, 1-minute sit-ups, standing broad jump, 40-m sprint, and 20-m shuttle run. Obese subjects had poorer scores in the field tests except in the sit-and-reach test. BMI and WC were significantly negatively associated with all the physical fitness parameters, except for the 40-m sprint where positive correlation was observed, and in the sit-and-reach test where no correlation was seen. In the management of preadolescent overweight and obesity, exercise programs should therefore be designed toward enhancing these fitness parameters, while not sacrificing enjoyment and creativity.

    Waist circumference (WC) has emerged as an independent predictor of cardiometabolic disease. The purpose of this study was to examine differences between overweight adults with and without WC risk in four domains: demographic, clinical and biological, psychological, and behavioral. The sample (N = 87) was primarily sedentary, middle-aged, women, and African-Americans. The majority of participants had WC risk, those with WC risk were older, were women, and had higher body mass index, higher morning salivary cortisol levels, and more depressive symptoms than those without WC risk. Caloric and macronutrient intake did not differ between those with and without WC risk. Our findings could lead to the development of targeted interventions to prevent and/or reduce abdominal obesity, thereby reducing cardiometabolic risk. Copyright © 2010 Wiley Periodicals, Inc.

    Augmented waist circumference (WC) is associated with non-communicable diseases and could represent a valuable marker in screening for metabolic dysfunctions in subjects with insufficient linear growth. The objective of the present study was to determine whether biochemical and hemodynamic parameters and waist circumference vary between mildly-stunted and non-stunted adolescents from impoverished communities of São Paulo, Brazil. The cross-sectional study involved 206 subjects, aged between 9 and 19 years and living in impoverished areas of São Paulo, Brazil. The sample population was divided according to height-for-age Z-score (HAZ) into stunted (-1 > HAZ ≥ -2) and non-stunted (HAZ ≥ -1) groups, and was sub-divided according to gender. Logistic regression analysis was employed to compare individuals with elevated (> 75th percentile) insulin concentrations. The receiver operating characteristic curves were constructed to determine WC cut-off points that could be used to identify stunted and non-stunted individuals with elevated insulin concentrations. WC cut-off points of 58.25cm and 67.2cm allowed for correct classification of 90.7% of stunted and 88.7% of non-stunted individuals in the studied population. While the sensitivity of the model was high for stunted and non-stunted subjects (98.8% and 97.2%, respectively), the specificity was modest (57.1% and 41.2%, respectively). The results presented herein suggest that an increase in plasma insulin is one of the primary metabolic modifications in stunted individuals, and that this alteration could be identified at a lower WC cut-off point than in non-stunted counterparts.

    Both visceral obesity and depression are associated with impaired health and excess mortality, possibly through overlapping pathophysiological mechanisms like adipose tissue derived inflammatory markers. These results, however, are primarily based on population-based surveys, often restricted to a young population and depression severity scales instead of patients with established diagnosis of depressive disorder. We examined the relation between waist circumference and late-life depression using the baseline data of The Netherlands Study of Depression in Older people (NESDO). Psychopathology has been assessed with Composite International Diagnostic Interview version 2.1. Adjusted for age, sex, education, lifestyle (smoking, alcohol, physical activity), drug use, cognition and chronic diseases as well as adjusted for body mass index (BMI), analysis of covariance showed that depressed older patients (n=376) had a significantly lower waist circumference (WC) compared to their non-depressed comparisons (n=130): estimated marginal mean (SE)=93.9 (0.5) versus 97.8 (0.8) cm (F=15.9; df=1467; pdepressed group showed that both, depression severity (Inventory of Depressive Symptoms) as well as duration-related depression characteristics (age of onset, duration of illness, life-time comorbid dysthymia), were associated with the WC. Only the severity of depressive symptoms remained significant after further adjusted for the BMI. Interestingly, a recently discovered adipokine, Neutrophil Gelatinase-Associated Lipocalin (NGAL), was associated with late-life depression, but only in the subgroup of patients with a pathologically increased WC. Population-based findings on the positive association between obesity and depressive symptoms can thus not be generalised to a clinical sample of depressed older patients. The impact of the WC on course and treatment outcome of late-life depression should be examined in clinical samples, taken into account the relative impact of the WC in

    Full Text Available Objective: Augmented waist circumference (WC is associated with non-communicable diseases and could represent a valuable marker in screening for metabolic dysfunctions in subjects with insufficient linear growth. The objective of the present study was to determine whether bio-chemical and hemodynamic parameters and waist circumference vary between mildly-stunted and non-stunted adolescents from impoverished communities of São Paulo, Brazil. Methods: The cross-sectional study involved 206 subjects, aged between 9 and 19 years and living in impoverished areas of São Paulo, Brazil. The sample population was divided according to height-for-age Z-score (HAZ into stunted (−1 > HAZ ≥ −2 and non-stunted (HAZ ≥ −1 groups, and was sub-divided according to gender. Logistic regression analysis was employed to compare individuals with elevated (> 75th percentile insulin concentrations. The receiver operating characteristic curves were constructed to determine WC cut-off points that could be used to identify stunted and non-stunted individuals with elevated insulin concentrations. Results: WC cut-off points of 58.25 cm and 67.2 cm allowed for correct classification of 90.7% of stunted and 88.7% of non-stunted individuals in the studied population. While the sensitivity of the model was high for stunted and non-stunted subjects (98.8% and 97.2%, respectively, the specificity was modest (57.1% and 41.2%, respectively. Conclusion: The results presented herein suggest that an increase in plasma insulin is one of the primary metabolic modifications in stunted individuals, and that this alteration could be identified at a lower WC cut-off point than in non-stunted counterparts.

    The primary aim of this study was to describe the carbonated beverage (soft drink) consumption patterns of New Zealand (NZ) youth and to investigate the influence that home availability of soft drinks had on their consumption. A secondary aim was to determine if there was an association between soft drink consumption and body mass index (BMI) or waist circumference. Data from Youth '07, a nationally representative survey of the health and well-being of NZ youth, including 8,697 NZ students aged 13 to 17 years, were analysed. The relevant data was available for 8697 students of whom 4633 identified as NZ European. 1621 Māori, 1.098 Asian, 834 Pacific, and 504 Other. Twenty nine percent (29%) were categorised as high consumers of soft drinks (>4 times a week), 45.4% were moderate consumers (1-3 times a week), and 25.6% were low consumers (had not consumed soft drinks in the past week). Male gender, Pacific ethnicity, and high deprivation were all significantly associated with being in the high consumer group. Fifty eight percent (58%) of children who reported that soft drinks were 'usually' available at home were in the high consumption group, compared to 15.1% of children who reported that these drinks were never available at home. After adjusting for possible confounders, waist circumference was significantly associated with soft drink consumption (pdrink consumption for boys was 3.5 times per week and was 2.0 for girls. This study provides detailed information on soft drink consumption patterns of NZ youth and highlights factors associated with high consumption. Moderating the availability of soft drinks in the home is likely to significantly reduce their consumption among NZ youth.

    Brain development in early childhood is a key determinant of later cognition, social achievement and educational success. Head circumference (HC) measurements are a simple method to assess brain growth, yet reports of these measurements are uncommon in nutritional surveys of undernourished children. To evaluate HC measurements in a population of rural Nepali children and relate these measurements to demographics, health and diet. An observational study of head growth was nested within a longitudinal evaluation of a livestock-based agricultural intervention in rural Nepal. Between 538 and 689 children (aged 6 months to 8 years) were measured (height, weight, HC) at each of six survey visits. A total of 3652 HC measurements were obtained. Results were converted to Z-scores (WHO Anthro). Mean head circumference Z-scores (HCZ) diminished progressively over the first 4 years of life; a decline of 30% occurred between 3 and 4 years of age (-1.73 to -2.45, P children children was explained by WAZ and ASF consumption. HCs reflect brain size in young children; brain size is linked to cognitive function. Poor head growth represents another facet of the 'silent emergency' of child undernutrition. Routine HCZ assessments may contribute to better understanding of the links between poverty and cognitive development.

    Preliminary data suggest an association between infant mortality rates and several measures of ambient air pollution, including dustfall and polycyclic aromatic hydrocarbons (PAH). The effects of airborne PAH components on fetal growth and early childhood development are of primary interest since we have previously demonstrated that these pollutants were associated with significant decrements in birth weight, length and head circumference in Polish newborn babies. The undertaken research combines a state-of-the-art environmental monitoring and molecular approaches with comprehensive neurodevelopment assessments. A further innovation is the incorporation of biomarkers (lead and antioxidants in cord blood) to control for potential confounding of exposure-effect. The mean overall concentrations of specific PAH compounds in Krakow, Poland were highest for benzo(b)fluoranthene (23 ng/m{sup 3}), benzo(a)anthracene, indeno(1,2,3-cd)pyrene, chyresene and benzo(a)pyrene. Concentrations of the PAH compounds measured by personal monitoring were higher in residents of the higher polluted area of the city. Comparison between the Krakow and New York City ambient data demonstrates that the concentrations and proportions of specific compounds in the total PAH mixture differ widely across these cities. Thus, one may expect that the PAH-related health risks would differ between the two areas not only because exposures are different, but also because the PAH profile differs. Presumably, this different profile is a consequence of variations in the sources of fossil and solid fuels used to produce energy. In Poland, more coal is used than in New York City. Auto emissions for example, are low in benzo(a)pyrene, whereas such emissions from refuse burning are high. 31 refs.

  10. Albuminuria and neck circumference are determinate factors of successful accurate estimation of glomerular filtration rate in high cardiovascular risk patients.

    Directory of Open Access Journals (Sweden)

    Po-Jen Hsiao

    Full Text Available Estimated glomerular filtration rate (eGFR is used for diagnosis of chronic kidney disease (CKD. The eGFR models based on serum creatinine or cystatin C are used more in clinical practice. Albuminuria and neck circumference are associated with CKD and may have correlations with eGFR.We explored the correlations and modelling formulates among various indicators such as serum creatinine, cystatin C, albuminuria, and neck circumference for eGFR.Cross-sectional study.We reviewed the records of patients with high cardiovascular risk from 2010 to 2011 in Taiwan. 24-hour urine creatinine clearance was used as the standard. We utilized a decision tree to select for variables and adopted a stepwise regression method to generate five models. Model 1 was based on only serum creatinine and was adjusted for age and gender. Model 2 added serum cystatin C, models 3 and 4 added albuminuria and neck circumference, respectively. Model 5 simultaneously added both albuminuria and neck circumference.Total 177 patients were recruited in this study. In model 1, the bias was 2.01 and its precision was 14.04. In model 2, the bias was reduced to 1.86 with a precision of 13.48. The bias of model 3 was 1.49 with a precision of 12.89, and the bias for model 4 was 1.74 with a precision of 12.97. In model 5, the bias could be lower to 1.40 with a precision of 12.53.In this study, the predicting ability of eGFR was improved after the addition of serum cystatin C compared to serum creatinine alone. The bias was more significantly reduced by the calculation of albuminuria. Furthermore, the model generated by combined albuminuria and neck circumference could provide the best eGFR predictions among these five eGFR models. Neck circumference can be investigated potentially in the further studies.

    The Chinese Head Trauma Data Bank (CHTDB) has been established, which includes 7,145 hospitalised cases with acute head trauma patients in 47 hospitals. We explored factors that might affect the outcome of acute traumatic brain injury. There was no statistical difference in the mortality rate between male (7.5%) and female (7.2%) patients (P>0.05). The mortality rate in children (65 years) was 7.3%, 7.2% and 9.0%, respectively (P>0.05). The mortality rate of patients with mild (2.7%), moderate (5.0%) and severe (21.8%) head trauma was significantly different (P40 mm Hg was 6.3%, 21.4% and 93.1%, respectively (Phead trauma data bank in China, has one of the largest numbers of cases of any head trauma data bank in the world.

    Pediatric abusive head trauma is a challenging subject across many disciplines. Of particular importance is the identification of mimics of abuse, so cause and manner of death can be properly assigned. We present the case of suspected child abuse involving an infant who presented unresponsive to the hospital with hypoglycemia, hypothermia, and bilateral parietal fractures. An autopsy revealed fractures associated with organizing scalp hemorrhage and gross leptomeningeal congestion and hemorrhage. The fractures were circular with external displacement, rounded margins, and subperiosteal new bone formation indicative of healing. Birth records revealed vacuum assist and cesarean section delivery. Although vacuum extraction-related injuries are typically cephalohematomas and/or linear fractures, the outbending and circular morphology of the fractures are consistent with vacuum extraction. Moreover, microscopic neuropathological examination revealed hemorrhagic purulent leptomeningitis. This unique case demonstrates the importance of considering birth trauma in the determination of cause and manner of death of an infant. © 2017 American Academy of Forensic Sciences.

  16. A National Census of Birth Weight in Purebred Dogs in Italy

    Full Text Available Despite increasing professionalism in dog breeding, the physiological range of birth weight in this species remains unclear. Low birth weight can predispose to neonatal mortality and growth deficiencies in humans. To date, the influence of the morphotype on birth weight has never been studied in dogs. For this purpose, an Italian census of birth weight was collected from 3293 purebred pups based on maternal morphotype, size, body weight and breed, as well as on litter size and sex of pups. Multivariate analysis outcomes showed that birth weight (p < 0.001 and litter size (p < 0.05 increased with maternal size and body weight. Birth weight was also influenced by the maternal head and body shape, with brachycephalic and brachymorph dogs showing the heaviest and the lightest pups, respectively (p < 0.001. Birth weight decreased with litter size (p < 0.001, and male pups were heavier than females (p < 0.001. These results suggest that canine morphotype, not only maternal size and body weight, can affect birth weight and litter size with possible practical implications in neonatal assistance.

    The first part of the study involved data collection for the detection of geographic variations and chronologic fluctuations in the rates of shoulder dystocia. The second part of the research evaluated head-to-body delivery times in cases of arrest of the shoulders at birth that had resulted in fetal damage during the last four decades in the USA. The study of geographic and chronologic changes in the rates of shoulder dystocia rested on reported statistics coming from the USA and 11 other countries. These data were obtained by computer search. Evaluation of head-to-body delivery times rested on 104 well-documented cases that resulted in permanent neonatal damage. Literary reports of shoulder dystocia indicate that the incidence of shoulder dystocia has increased in the USA about fourfold since the middle of the twentieth century. No comparable trend has been reported from most other countries. Study of head-to-body delivery times revealed that more than two-thirds of all injured fetuses had been extracted from the birth canal within 2 minutes. Incidents of shoulder dystocia began to escalate in the USA during the 1980s, shortly after the introduction of "active management" of the birthing process. This new technique replaced a conservative philosophy which had recommended abstinence from intervention on the part of the accoucheur. The authors consider the interventionist approach largely responsible for the exponential increase in the rates of shoulder dystocia in the USA. They recommend adherence to the traditional method of delivery on the part of obstetricians in Europe and elsewhere.

Nineteen buffaloes, with initial ages between 11 and 59 months,were submitted to fortnightly collections of semen for a period of six months. At each collection the testicular biometry and testicular echogenicity were evaluated as well as blood samples were also collected to measure the plasma testosterone levels. The data were submitted to analysis of variance by the GLM procedure, considering the age group fixed effect. The average data obtained were compared by the Duncan test, at 5% significance. There was a significant growth (P<0.05 of the scrotal circumference, which varied from 12.88±0.51 cmto 31.18±0.75 cm among animals aged 12 to 60 months, as well as testicular volume, which ranged from 30.28±17.37 to 611.96±38.69 cm³ among the animals. The echogenic intensity of the testicular parenchyma varied in pixels from 78.67±6.36 to 109.24±3.13 in animals aged 12 to 60 months respectively.

    To analyze the association between higher body mass index and waist circumference, and the prognostic values of both indicators in total and cardiac mortality in patients with chronic heart failure. The study included 2254 patients who were followed up for 4 years. Obesity was classified as a body mass index ≥30 and overweight as a body mass index of 25.0-29.9. Central obesity was defined as waist circumference ≥88 cm for women and ≥102cm for men. Independent predictors of total and cardiac mortality were assessed in a multivariate Cox model adjusted for confounding variables. Obesity was present in 35% of patients, overweight in 43%, and central obesity in 60%. Body mass index and waist circumference were independent predictors of lower total mortality: hazard ratio=0.84 (P120cm. Mortality was significantly lower in patients with a high body mass index and waist circumference. The results also showed that this protection was lost when these indicators over a certain limit.

    [Purpose] The purpose of this study was to investigate the effects of interferential current therapy on the waist circumference and visceral fat length in obese women. [Subjects and Methods] In this study, we selected 30 patients whose body mass index was over 25 kg/m2. The subjects were randomly assigned to receive interferential current therapy three times a week for four weeks (n=15) and transcutaneous electrical nerve stimulation three times a week for four weeks (n=15). Waist circumference was measured in cm using a tape measure with the participant in an upright posture, and the length of visceral fat was measured using a high-resolution, B-mode ultrasound machine. [Results] There was a statistically significant difference between the group of waist circumference and visceral fat length. The change of waist circumference and visceral fat length was larger the experimental group than the control group. [Conclusion] These results can be used as a basis for reducing the risk factors that increase mortality due to diseases and can prevent cardiovascular and other adult diseases caused by obesity.

    Full Text Available Abstract Background Obesity is common in the U.S. and many individuals turn to commercial programs to lose weight. Our objective was to directly compare weight loss, waist circumference, and systolic and diastolic blood pressure (SBP, DBP outcomes between commercially available weight-loss programs. Methods We conducted a systematic review by searching MEDLINE and the Cochrane Database of Systematic Reviews from inception to November 2014 and by using references identified by commercial programs. We included randomized, controlled trials (RCTs of at least 12 weeks duration that reported comparisons with other commercial weight-loss programs. Two reviewers extracted information on mean change in weight, waist circumference, SBP and DBP and assessed risk of bias. Results We included seven articles representing three RCTs. Curves participants lost 1.8 kg (95%CI: 0.1, 3.5 kg more than Weight Watchers in one comparison. There was no statistically significant difference in waist circumference change among the included programs. The mean reduction in SBP for SlimFast participants was 4.5 mmHg (95%CI: 0.4, 8.6 mmHg more than that of Atkins participants in one comparison. There was no significant difference in mean DBP changes among programs. Conclusions There is limited evidence that any one of the commercial weight-loss programs has superior results for mean weight change, mean waist circumference change, or mean blood pressure change.

  2. Economic influences on birth rates.

    Ermisch, J

    1988-11-01

    A researcher uses an econometric analysis to test his theory that economic developments influence birth rates in post World War II in Great Britain. The base of the analysis consists of a group of equilibrium relationships examining the levels of conditional birth rates (at each birth order and each mother's age) and the levels of economic variables, e.g., ratio of women's hourly wage after taxes. The leading cause of a decrease in births, especially after 1974, was an increase in women's net wages in comparison to men's net wages. Additional evidence suggested that higher women's wages increase the cost of an additional child by raising missed earnings, and this higher opportunity cost reduces the chance of another birth. On the other hand, if men's earnings are higher, couples have more children and at a young age. Further, the higher the real house prices the more likely women are to postpone starting a family and, in the case of 20-24 year old women, these high prices also deter them from having a 2nd child. Higher house prices do not affect higher order births, however. When all other things are equal, women from larger families have a tendency to begin having children in their 30s and produce smaller families than those women from smaller families. Large child allowances encourage 3rd-4th births and early motherhood. To increase fertility to replacement level over the long term, the current level of child allowances would have to double costing about 5 billion British pounds or 1.5% of the gross domestic product.

    Full Text Available Objectives: It is not clear what type of pre-crimped crown is more successful in achieving greater marginal adaptation following re-crimping. This study aimed to assess the changes in the circumference of 3M ESPE and MIB pre-crimped stainless steel crowns (SSCs for the primary maxillary and mandibular first and second molars following re-crimping.Materials and Methods: This was an in-vitro, experimental study. Initial photographs were obtained from the margins of 3M and MIB SSCs for the upper and lower primary molars using a digital camera. Crown margins were crimped by applying 0.2N force using 114 and 137 pliers. Post-crimping photographs were also obtained and the changes in crown circumference after crimping were calculated using AutoCad software. The percentage of reduction in the circumference of crowns for each tooth was statistically analyzed based on the type of crown using student t-test. The effect of crown design and the associated teeth on the decreased circumference percentage was statistically analyzed by two-sided ANOVA.Results: The percentage of reduction in lower E SSC circumference was 3.71±0.39% in MIB and 6.29±0.62% in 3M crowns. These values were 3.55±0.55% and 7.15±1.13% for the lower Ds, and 3.95±0.43 and 6.24±0.85% for the upper Ds, respectively. For the upper Es, these values were found to be 3.12±0.65% and 5.14±0.94%, respectively. For each tooth, a significant difference was found between MIB and 3M SSCs in terms of the percentage of reduction in crown circumference following crimping. The magnitude of this reduction was smaller in MIB compared to 3M SSCs (P<0.001.Conclusion: Considering the significant reduction in the marginal circumference of pre-crimped SSCs following re-crimping, it appears that this manipulation must be necessarily performed for MIB and 3M pre-crimped SSCs. By using 3M SSCs, higher marginal adaptation can be achieved following crimping.

  12. Liberalization of Birth Control and the Unmarried Share of Births

    DEFF Research Database (Denmark)

    Kennes, John; Knowles, John

    Half of unmarried births are to women who are already mothers, and a quarter to women who were previously married. We develop a model of equilibrium matching and fertility to replicate these facts. We use the model to revisit the hypothesis that liberalization of the Pill and abortion caused...... the massive increase since 1960 in the share of US births to unmarried women. Our results suggest that liberalization alone is ineffective; what matters are interactions between liberalization and the decline in the stability of marriage, and, secondarily, the rising status of single mothers....

    Full Text Available Abstract Background Caesarean section rates in Brazil have been steadily increasing. In 2009, for the first time, the number of children born by this type of procedure was greater than the number of vaginal births. Caesarean section is associated with a series of adverse effects on the women and newborn, and recent evidence suggests that the increasing rates of prematurity and low birth weight in Brazil are associated to the increasing rates of Caesarean section and labour induction. Methods Nationwide hospital-based cohort study of postnatal women and their offspring with follow-up at 45 to 60 days after birth. The sample was stratified by geographic macro-region, type of the municipality and by type of hospital governance. The number of postnatal women sampled was 23,940, distributed in 191 municipalities throughout Brazil. Two electronic questionnaires were applied to the postnatal women, one baseline face-to-face and one follow-up telephone interview. Two other questionnaires were filled with information on patients’ medical records and to assess hospital facilities. The primary outcome was the percentage of Caesarean sections (total, elective and according to Robson’s groups. Secondary outcomes were: post-partum pain; breastfeeding initiation; severe/near miss maternal morbidity; reasons for maternal mortality; prematurity; low birth weight; use of oxygen use after birth and mechanical ventilation; admission to neonatal ICU; stillbirths; neonatal mortality; readmission in hospital; use of surfactant; asphyxia; severe/near miss neonatal morbidity. The association between variables were investigated using bivariate, stratified and multivariate model analyses. Statistical tests were applied according to data distribution and homogeneity of variances of groups to be compared. All analyses were taken into consideration for the complex sample design. Discussion This study, for the first time, depicts a national panorama of labour and birth

    We study the impact of marriages resulting from bride kidnapping on infant birth weight. Bride kidnapping-a form of forced marriage-implies that women are abducted by men and have little choice other than to marry their kidnappers. Given this lack of choice over the spouse, we expect adverse consequences for women in such marriages. Remarkable survey data from the Central Asian nation of Kyrgyzstan enable exploration of differential birth outcomes for women in kidnap-based and other types of marriage using both OLS and IV estimation. We find that children born to mothers in kidnap-based marriages have lower birth weight compared with children born to other mothers. The largest difference is between kidnap-based and arranged marriages: the magnitude of the birth weight loss is in the range of 2 % to 6 % of average birth weight. Our finding is one of the first statistically sound estimates of the impact of forced marriage and implies not only adverse consequences for the women involved but potentially also for their children.

    Full Text Available Introduction. The prevalence of obesity is increasing worldwide. Obesity can be determined by body mass index (BMI; however waist circumference (WC is a better measure of central obesity. This study evaluates the outcome of laparoscopic nephrectomy on patients with an abnormal WC. Methods. A WC of >88 cm for women and >102 cm for men was defined as obese. Data collected included age, gender, American Society of Anaesthesiologists (ASA score, renal function, anaesthetic duration, surgery duration, blood loss, complications, and duration of hospital stay. Results. 144 patients were assessed; 73 (50.7% of the patients had abnormal WC for their gender. There was no difference between the groups for conversion to open surgery, number of ports used, blood loss, and complications. Abnormal WC was associated with a longer median anaesthetic duration, 233 min, IQR (215–265 versus 204 min, IQR (190–210, p=0.0022, and operative duration, 178 min, IQR (160–190 versus 137 min, IQR (128–162, p<0.0001. Patients with an abnormal WC also had a longer inpatient stay, p=0.0436. Conclusion. Laparoscopic nephrectomy is safe in obese patients. However, obese patients should be informed that their obesity prolongs the anaesthetic duration and duration of the surgery and is associated with a prolonged recovery.

    Microstructure of a polycrystalline material has a considerable influence on particular properties, such as mechanical strength, electrical conductivity, optical transmission and magnetic susceptibility. The uranium dioxide (UO{sub 2}) is used in water-cooled nuclear reactors, due to its desirable ceramics characteristics as a nuclear fuel. The UO{sub 2} is used in the form of pellets manufactured by wet route by INB, where they are loaded into fuel rods to build the fuel assemblies used in pressurized water reactors of Angra 1, Angra 2 and future Angra 3 nuclear power plants, for electric energy generated from nuclear power in Brazil. The geometric and structural integrity of these pellets cause direct influence on their performance during the reactor core operating cycle, so pellets presenting surface cracks leading to the phenomenon of pellet cladding interaction-PCI, resulting in failures in the fuel rod and subsequently release of fission products in the reactor coolant. Transverse cracks on surface area of pellet circumference are detected by visual inspection during the manufacturing process. This paper presents the study of these cracks formation by content analysis conducted with the support of electron microscopy. These results here are analyzed from the point of view of materials science through observation of the microstructure, and the pressing process where the defect was probably generated. (author)

    Findings on weight training and waist circumference (WC) change are controversial. This study examined prospectively whether weight training, moderate to vigorous aerobic activity (MVAA), and replacement of one activity for another were associated with favorable changes in WC and body weight (BW). Physical activity, WC, and BW were reported in 1996 and 2008 in a cohort of 10,500 healthy U.S. men in the Health Professionals Follow-up Study. Multiple linear regression models (partition/substitution) to assess these associations were used. After adjusting for potential confounders, a significant inverse dose-response relationship between weight training and WC change (P-trend weight training (-0.67 cm, 95% CI -0.93, -0.41) than for MVAA (-0.33 cm, 95% CI -0.40, -0.27), other activities (-0.16 cm, 95% CI -0.28, -0.03), or TV watching (0.08 cm, 95% CI 0.05, 0.12). Substituting 20 min/day of weight training for any other discretionary activity had the strongest inverse association with WC change. MVAA had the strongest inverse association with BW change (-0.23 kg, 95% CI -0.29, -0.17). Among various activities, weight training had the strongest association with less WC increase. Studies on frequency/volume of weight training and WC change are warranted. © 2014 The Obesity Society.

    To assess the relationship between the degree of waist circumference (WC) and nonalcoholic fatty liver disease (NAFLD) in obese adolescents of both genders, analyzed according to quartiles of WC. Cross-sectional study that involved 247 obese adolescents aged 12-19 years. Mean values of the nutritional parameters and serum analyses were compared with the groups using the independent t-test. Pearson correlation coefficient was used to determine the relationship of the parameters studied. Chi-square test for trend was used to determine the relationship between the prevalence of the NAFLD and WC quartile by gender. NAFLD were presented in 60% of the study participants. Obese adolescents in the 3rd and 4th quartiles of WC presented higher prevalence of NAFLD when compared with that in the 1st quartile in both genders. The NAFLD patients had significantly higher values for body weight, BMI (body mass index), BAZ-score (BMI-for-age z-scores), total fat (% and kg), WC, visceral fat, insulin, insulin resistance index (HOMA-IR), aspartate aminotransferase and alanine aminotransferase, when compared with non-NAFLD obese adolescents. The results presented here suggest that an increase in WC can reliably predict the risk of NAFLD in obese adolescents. This is a low cost and easy-to-use tool that can help in screening in adolescents. Copyright © 2015 Sociedade de Pediatria de São Paulo. Publicado por Elsevier Editora Ltda. All rights reserved.

    The prevalence of obesity in adolescents and children has risen to alarming levels globally and this has led to serious public health consequences. To assess the use of Mid-Upper Arm Circumference (MUAC) in the identification of overweight and obesity in North Indian children and adolescents. The study was conducted in Bareilly district of Uttar Pradesh, India, from October 2014 to November 2015. Anthropometric data (weight, height and MUAC) was collected from a cross-sectional sample of 875 children aged 5-14 year old. Receiver Operating Characteristic (ROC) curve analysis determined the validity of MUAC as a proxy for determining overweight and obesity. Area Under the Curve (AUC) results were generally high (0.92 - 0.98). The accuracy level of MUAC for identifying obesity was high in both sexes and across age groups (overall AUC of 0.95, sensitivity of 95% and specificity of 90%). The MUAC cut-off to identify BMI defined obesity was 18.8 cm and 19.4 cm for boys and girls of 5-9 age group; 23 cm and 23.3 cm for boys and girls of 10-14 age group. MUAC may have potential for clinical and surveillance applications as an accurate yet simple and widely available indicator of overweight and obesity in children and adolescents in resourcepoor settings.

    2015-01-01

    Rostral fluid shift during sleep from the lower body part into the neck can increase neck circumference (NC) and narrow the upper airway. Such narrowing in the upper airway may increase turbulence of airflow passing through the upper airway; thus, induce snoring. The objective of this study was to investigate the effects of changes in NC during sleep on snoring sound characteristics. Fifteen non-obese men slept supine, and their sleep was monitored by a regular polysomnography. Snoring sounds were recorded with a microphone attached to the neck. NC was measured before and after sleep with a measuring tape. Snoring sounds' average power was calculated in different frequency ranges of 100 - 4000 Hz, 100 - 150 Hz, 150 - 450 Hz, 450 - 600 Hz, 600 - 1200 Hz, 1200 - 1800 Hz, 1800 - 2500 Hz and 2500 - 4000 Hz. Statistical analysis showed that increases in NC after sleep were strongly correlated with higher average power of the snoring sounds in the frequency ranges of 100-4000 Hz (r=0.74, P=0.004), 100-150 Hz (r=0.70, P=0.008), 150-450 Hz (r=0.73, P=0.005), and 450 - 600 Hz (r= 0.65, P=0.025). These results encourage the use of snoring sound analysis for monitoring the effects of fluid accumulation in the neck in relation to sleep apnea.
