Double burden of malnutrition (DBM) is a global public health concern. This study determined the prevalence of DBM and its associated factors among 451 indigenous households in an urbanized state of Malaysia. Mothers and children were measured for weight and height/length. Mothers were interviewed for socio-demographics and diets of mothers and children. Prevalence of DBM (overweight/obese mother and underweight/stunted child) was 28.8%. Food insecurity, maternal height (<150 cm) and energy intake (>recommendation), child's age (≥24 months) and energy intake (

Background: Atrial fibrillation (AF) is prevalent in patients with type 2 diabetes mellitus (T2DM). Obesity commonly accompanies T2DM, and increases the risk of AF. However, the dose-relationship between body mass index (BMI) and AF risk has seldom been studied in patients with diabetes., Methods: This cohort study utilized a database from National Taiwan University Hospital, a tertiary medical center in Taiwan. Between 2014 and 2019, 64,339 adult patients with T2DM were enrolled for analysis. BMI was measured and categorized as underweight (BMI < 18.5), normal (18.5 ≤ BMI < 24), overweight (24 ≤ BMI < 27), obesity class 1 (27 ≤ BMI < 30), obesity class 2 (30 ≤ BMI < 35), or obesity class 3 (BMI ≥ 35). Multivariate Cox regression and spline regression models were employed to estimate the relationship between BMI and the risk of AF in patients with T2DM., Results: The incidence of AF was 1.97 per 1000 person-years (median follow-up, 70.7 months). In multivariate Cox regression, using normal BMI as the reference group, underweight (HR 1.52, 95% CI 1.25-1.87, p < 0.001) was associated with a significantly higher risk of AF, while overweight was associated with significantly reduced risk of AF (HR 0.82, 95% CI 0.73-0.89, p < 0.001). Kaplan-Meier analysis showed AF risk was highest in the underweight group, followed by obesity class 3, while the overweight group had the lowest incidence of AF (log-rank test, p < 0.001). The cubic restrictive spline model revealed a "J-shaped" or "L-shaped" relationship between BMI and AF risk., Conclusions: Underweight status confers the highest AF risk in Asian patients with T2DM., (© 2021.

Objective: Preterm birth (PTB) and food insecurity are two of the most significant public health crises in the United States. Effects of being underweight among populations with low food security are not well understood. We assess whether the protective effect of gestational weight gain (GWG) for women with low prepregnancy body mass index (BMI) differs by accessibility to sources of healthy food., Study Design: Population-based retrospective cohort study using Ohio birth records analyzing all live births, 2006 to 2015. Analyses were stratified by maternal BMI (underweight, normal, overweight, and obese), Institute of Medicine (IOM) recommended GWG (under vs. met), and whether the U.S. Department of Agriculture (USDA) classified the residential census tract for each birth as a food desert. Food access data were retrieved from the USDA's 2018 Food Access Research Atlas. Covariates were selected using least absolute shrinkage and selection operator regression. Logistic regression models estimated the risk ratio (RR) of PTB for each group based on under or exceeded recommended GWG (reference = met), adjusting for coexisting risk factors., Results: Analysis was performed on 1,124,299 births. PTB risk was highest for underweight women below GWG recommendations (no food desert: 21.3%, RR = 2.15, 95% confidence interval [CI]: 1.81-2.57; food desert: 21.0%, RR = 1.46, 95% CI: 0.96-2.21). Underweight women living in food deserts who exceeded GWG recommendations had lower PTB risk than those who met GWG recommendations (13.5 vs. 14.3%, RR = 0.85, 95% CI: 0.51-1.41). Factors other than GWG significantly associated with PTB included in the adjusted analysis include maternal age and race, education, marital status, interpregnancy interval, and presence of prepregnancy diabetes or hypertension., Conclusion: Underweight women who do not meet GWG recommendations are at high risk for PTB. Increasing pregnancy weight gain to a level that exceeds IOM recommendations was not associated with a reduction in PTB risk for underweight women who reside in food deserts compared with women who met GWG recommendations., Key Points: · Women with low prepregnancy BMI are at high risk of PTB.. · Food insecurity increases the risk of PTB for underweight women.. · Excessive GWG for underweight women in food deserts does not reduce PTB risk.., Competing Interests: None declared., (Thieme.

Background: The albumin-to-alkaline phosphatase ratio (AAPR) is a newly developed index of liver function, but its association in patients with non-alcoholic fatty liver disease (NAFLD) has not been established. The aim of this study was to investigate the association between the AAPR and NAFLD in a non-obese Chinese population., Methods: The study included 10,749 non-obese subjects without NAFLD at baseline and divided them into quintiles according to the AAPR. A Cox multiple regression model was used to examine the association between the AAPR and its quintiles and the incidence of NAFLD., Results: The average age of the study population was 43.65 ± 15.15 years old. During the 5-year follow-up, 1860 non-obese subjects had NAFLD events. In the Cox multiple regression model, after adjusting the model according to important risk factors, the AAPR and NAFLD risk were independently correlated, and with a gradual increase in the AAPR, the NAFLD risk decreased gradually (HR: 0.61, 95% CI: 0.47, 0.81; P-trend< 0.0001). Additionally, there were significant interactions between the AAPR and BMI, blood pressure and lipids (P-interaction < 0.05). Stratified analysis showed that the risk of AAPR-related NAFLD decreased in people with normal blood pressure and lipid levels, while the risk of AAPR-related NAFLD increased abnormally in people who were underweight., Conclusions: This longitudinal cohort study provides the first evidence that the AAPR is an independent predictor of future NAFLD events in non-obese people. For non-obese people with a low AAPR, especially those with BMI < 18.5 kg/m 2 , more attention should be given to the management of risk factors for NAFLD to prevent future NAFLD.

Introduction: despite increasing research interest on Indigenous peoples´ health worldwide, the nutritional status of Indigenous children in Cameroon remains unknown. This study was conducted to assess the prevalence of stunting, wasting, and underweight among under-five Indigenous Mbororo children in the Foumban and Galim health districts of the West Region., Methods: a cross-sectional study was conducted involving 472 child-caregiver pairs from 16 Mbororo Communities in the Foumban and Galim health districts. Interviewer-administered questionnaires were used for data collection. Anthropometric measurements were collected using standard procedures. Socio-demographic data were analyzed using descriptive statistics. Anthropometric indices: height-for-age, weight-for-height, and weight-for-age - z-scores were analyzed using z-score 06 Stata version 11 and compared with World Health Organization growth reference standards. Ethical approval was obtained from the Faculty of Health Sciences Institutional Review Board of the University of Buea., Results: overall prevalence of stunting, wasting and underweight were 55.08% (95% CI: 50.5-59.58), 13.77% (95% CI: 10.65-16.89), and 31.99% (95% CI: 27.76-36.21), respectively. Severe stunting, wasting and underweight were 34.53% (95% CI: 30.22-38.83), 3.18% (95% CI: 1.58-4.76), and 10.59% (95% CI: 7.80-13.37), respectively. Rates of stunting, wasting and underweight for female and male were: 56.88% and 52.71%; 12.38% and 14.72%; and 30.73% and 32.55%, respectively. Stunting, wasting and underweight rates varied with child age., Conclusion: the prevalence of undernutrition was high, indicating a serious public health problem and the necessity for strategies to ensure the optimal health of the target population., Competing Interests: The authors declare no competing interests., (Copyright: Florence Titu Manjong et al.)

In Botswana, there is limited data available on the health and nutritional status of the San People (also known as the Basarwa or Bushmen), an Indigenous minority group primarily living in the Ghanzi District. Our aim in this study was to assess anemia prevalence among and anthropometric indices of women and young children in Ghanzi District through a cross-sectional survey. We recruited 367 mother-child pairs (women 15-49 years and children 6-59 months) in nine randomly selected areas. A capillary blood sample was collected, and weight and height were measured. Hemoglobin (Hb) concentration was measured with use of a hemoglobinometer (HemoCue, AB), as per global recommendations. Overall, adjusted anemia prevalence was 12% in non-pregnant women (Hb < 120 g/L), 26% in pregnant women (Hb < 110 g/L), and 42% in children (Hb < 110 g/L), but it varied widely depending on whether or not the controversial factor of ethnicity was adjusted for (range of 6-26%, 22-30%, and 35-68% prevalence, respectively). Thirty-nine percent ( n = 133/344) of non-pregnant women and 52% ( n = 12/23) of pregnant women were underweight (BMI < 18.5 kg/m 2 ). In children aged 6-23 months, 41% were underweight (weight-for-age z -score < -2 SD), 13% were wasted (weight-for-height z -score < -2 SD), and 65% were stunted (height-for-age z -score < -2 SD); in children aged 24-59 months, 57% were underweight, 13% were wasted, and 66% were stunted. Fifty-six percent ( n = 205/367) of women self-reported smoking in any form (rolled cigarettes or snuffing). The high prevalence of smoking among women, underweight status among pregnant women, and anemia, stunting, and wasting among children is of the highest concern for public health and should be addressed in future health and nutrition programming.

Introduction: Women migrating to high-income countries may have increased risks of adverse pregnancy outcomes as compared with native-born women. However, little is known whether migrant women are more likely to have unhealthy body mass index (BMI) or gestational weight gain (GWG), which is of importance considering the well-established links between unhealthy BMI and GWG with adverse pregnancy outcomes. Hence, the aim of the study was to examine the prevalence and estimate odds ratios (ORs) of underweight and obesity in the first trimester as well as inadequate and excessive GWG across birth regions in migrant (first-generation) and Swedish-born women in a population-based sample of pregnant women in Sweden., Methods: This population-based study included 535 609 pregnancies from the Swedish Pregnancy Register between the years 2010-2018. This register has a coverage of approximately 90% and includes data on body weight, height, birth country and educational attainment. BMI in the first trimester of pregnancy was classified as underweight, normal weight, overweight and obesity whereas GWG was classified as inadequate, adequate and excessive according to the recommendations from the National Academy of Medicine, USA. BMI and GWG were examined according to 7 birth regions and the 100 individual birth countries. Adjusted ORs of underweight, obesity as well as inadequate or excessive GWG by birth regions were estimated using multinomial logistic regression., Results: There were large disparities in unhealthy BMI and GWG across birth regions. For instance, women born in North Africa and Middle East and Sub-Saharan Africa had 1.40 (95% CI 1.35-1.44) and 2.13 (95% CI 2.03-2.23) higher odds of obesity compared with women born in Sweden. However, women born in Sub-Saharan Africa had also considerably higher odds of underweight (OR, 2.93 [95% CI 2.70-3.18]) and inadequate GWG (OR, 1.97 [95% CI 1.87-2.07]). The limitations of the study include the lack of a validated measure of acculturation and that the study only had data on first-generation migration., Conclusions: The large differences across the 7 regions and 100 countries highlights the importance of considering birth region and country-specific risks of unhealthy BMI and GWG in first-generation migrant women. Furthermore, inadequate GWG was common among pregnant first-generation migrant women, especially in women born in Sub-Saharan Africa, which demonstrates the need to promote adequate GWG, not only the avoidance of excessive GWG. Thus, our findings also indicate that additional support and interventions may be needed for first-generation migrant women from certain birth regions and countries in order to tackle the observed disparities in unhealthy BMI and GWG. Although further studies are needed, our results are useful for identifying groups of women at increased risk of unhealthy BMI and weight gain during pregnancy., Competing Interests: I have read the journal's policy and the authors of this manuscript have the following competing interests: Marcus Bendtsen owns a private company that develops and distributes lifestyle interventions to be used in health care settings although this company has no link to this study. This does not alter our adherence to PLOS ONE policies on sharing data and materials. All remaining authors declare no competing interests.

This study aimed to rigorously assess body weight perceptions according to several body image dimensions in rural, employed African women. One hundred and thirty-two employed black African women were recruited at a rural South African university. Participants were asked to choose their 'ideal' and 'feel' perceived body size from nine standardized body image silhouettes, varying according to body size. Three body image dimensions of interest were measured, (1) 'feel' minus 'ideal' index (FID), (2) perceived minus the actual weight status (PAD) index and (3) valorization of stoutness index (participants that chose silhouettes corresponding to overweight/obesity). Using the FID dimension, older obese women had significantly higher desire for leanness, with small effects, compared with lean and younger obese women ( p = .001). Those women who correctly perceived body weight (PAD = 0), were mostly obese and older ( p < .0001), with moderate effects, than non-obese women. Social valorization of stoutness was observed in 58.3% of the sample, but was higher in older obese women, with small effects, compared with lean women ( p = .0001). This study has shown that the majority of the study population demonstrated a social valorization of stoutness, despite a desire to be thinner and the ability to adequately perceive their own body weight in accordance with BMI.

Background: Social inequalities in bodyweight start early in life and track into adulthood. Dietary patterns are an important determinant of weight development in children, towards both overweight and underweight. Therefore, we aimed to examine weight development between age 5 and 10 years by ethnicity, SES and thereafter by BMI category at age 5, to explore its association with dietary patterns at age 5., Methods: Participants were 1765 children from the Amsterdam Born Children and their Development (ABCD) cohort that had valid data on BMI at age 5 and 10 and diet at age 5. Linear mixed model analysis was used to examine weight development between age 5 and 10 years and to assess if four previously identified dietary patterns at age 5 (snacking, full-fat, meat and healthy) were associated with weight development. Analyses were adjusted for relevant confounders, stratified by ethnicity and SES and thereafter stratified per BMI category at age 5., Results: Overall, weight decreased in Dutch and high SES children and increased in non-Dutch and low/middle SES children. Across the range of bodyweight categories at age 5, we observed a conversion to normal weight, which was stronger in Dutch and high SES children but less pronounced in non-Dutch and low/middle SES children. Overall, the observed associations between weight development and dietary patterns were mixed with some unexpected findings: a healthy dietary pattern was positively associated with weight development in most groups, regardless of ethnicity and SES (e.g. Dutch B 0.084, 95% CI 0.038;0.130 and high SES B 0.096, 95% CI 0.047;0.143) whereas the full-fat pattern was negatively associated with weight development (e.g. Dutch B -0.069, 95% CI -0.114;-0.024 and high SES B -0.072, 95% CI -0.119;-0.026)., Conclusions: We observed differential weight development per ethnic and SES group. Our results indicate that each ethnic and SES group follows its own path of weight development. Associations between dietary patterns and weight development showed some unexpected findings; follow-up research is needed to understand the association between dietary patterns and weight development.

Purpose: The study aimed to assess the prevalence of underweight and overweight or obesity and their sociodemographic, lifestyle, and health factors in a national adult population in Lao People's Democratic Republic (PDR) (Laos)., Methods: A national cross-sectional study based on a stratified cluster random sampling was conducted in 2013. The total sample included 2531 individuals 18-64 years, (females = 59.3%; mean age 38.7 years, SD = 12.8) from Laos. Questionnaire interview, blood pressure and anthropometric measurements, and biochemistry tests were conducted. Multinomial logistic regression was utilized to determine the association between sociodemographic, lifestyle and health status factors, and underweight and overweight or obesity relative to normal weight., Results: Using Asian criteria for body mass index (BMI) classification, 9.7% of the population was underweight (BMI < 18.5, kg/m 2 ), 47.5% had normal weight (BMI 18.5-22.9 kg/m 2 ), 17.5% overweight (23.0-24.9 kg/m 2 ), 19.6% class I obesity (BMI 25.0-29.9 kg/m 2 ), and 5.6% class II obesity (BMI ≥ 30.0 kg/m 2 ) (or 42.8% overweight, class I or class II obesity). In adjusted multinomial logistic regression, female sex (adjusted relative risk ratio-ARRR 0.67, confidence interval-CI 0.45, 0.99), current tobacco use (ARRR 1.57, CI 1.02, 2.41), and having no hypertension (ARRR 0.50, CI 0.26, 0.97) were associated with underweight, and middle and older age (ARRR 1.79, CI 1.41, 2.25), being Lao-Tai (ARRR 1.37, CI 1.06, 1.76), urban residence (ARRR 1.62, CI 1.20, 2.17), having meals outside home (ARRR 1.36, CI 1.04, 1.77), no current tobacco use (ARRR 0.57, CI 0.34, 0.59), low physical activity (ARRR 1.39, CI 1.01, 1.92), having hypertension (ARRR 2.52, CI 1.94, 3.26), and dyslipidaemia (ARRR 1.56, CI 1.21, 2.00) were associated with overweight or obesity., Conclusion: A dual burden of both adult underweight and overweight or obesity was found in Laos. Sociodemographic, lifestyle, and health status risk factors were identified for underweight and overweight or obesity, which can help in guiding public health programmes to address both these conditions., Level of Evidence: Level V, descriptive cross-sectional survey.

The growing number of women, who are characterized by restrictive and bulimic behaviours towards their own body is observed especially in countries influenced by Westernalization. However, there is a lack of cross-cultural studies in this area. The main aim of the present study was to examine the psychological and socio-cultural risk factors for eating disorders in Polish and Japanese women. A cross-sectional research study was conducted among 18- to 29-year old Polish ( n = 89) and Japanese ( n = 97) women. The variables were measured using the Sociocultural Attitudes Towards Appearance Scale SATAQ-3, and the Eating Disorders Inventory EDI-3. The descriptive and comparative statistics, Spearman's rho, and the stepwise regression analysis were used. The global internalization of socio-cultural standards of body image proved to be a significant predictor of Body Dissatisfaction among Polish and Japanese women. The main analysis showed a significant relation between the Drive for Thinness and Interoceptive Deficits in the group of Japanese women, as well as a correlation between Drive for Thinness and Asceticism in the group of Polish women. The obtained results could improve the prevention aimed the dysfunctional eating behaviours. However, the cultural nuances need to be considered in understanding the risk factors for eating disorders.

This study investigated whether the association between household air pollution (HAP) and nutritional status (stunting, underweight, or wasting) among children differ by caste/ethnicity. Child anthropometry data for 9,914 children aged 0-59 months were analyzed linearly as Z scores and as dichotomous categories. Exposure to HAP was significantly associated with a decrease in child height-for-age and child weight-for-age, as well as with stunting and underweight. Children in low caste (Dalits) had higher prevalence of stunting (odds ratio [OR] = 1.21; 95% confidence intervals [CI] = 1.01, 1.44), underweight (OR = 1.47; 95% CI = 1.24, 1.75), and wasting (OR = 1.53; 95% CI = 1.21, 1.92) than those children in upper caste group. This association was modestly attenuated with adjustment for HAP. Exposure to HAP partly explained the caste-ethnic difference in undernutrition among children in Nepal.

Living South Asians have low lean tissue mass relative to height, which contributes to their elevated type 2 diabetes susceptibility, particularly when accompanied by obesity. While ongoing lifestyle transitions account for rising obesity, the origins of low lean mass remain unclear. We analysed proxies for lean mass and stature among South Asian skeletons spanning the last 11,000 years (n = 197) to investigate the origins of South Asian low lean mass. Compared with a worldwide sample (n = 2,003), South Asian skeletons indicate low lean mass. Stature-adjusted lean mass increased significantly over time in South Asia, but to a very minor extent (0.04 z-score units per 1,000 years, adjusted R 2  = 0.01). In contrast stature decreased sharply when agriculture was adopted. Our results indicate that low lean mass has characterised South Asians since at least the early Holocene and may represent long-term climatic adaptation or neutral variation. This phenotype is therefore unlikely to change extensively in the short term, so other strategies to address increasing non-communicable disease rates must be pursued.

Few studies have examined age or cultural differences in the stereotypes adolescents have of persons with obesity. The present research explored the hypotheses that American adolescents have more negative obesity stereotypes than Chinese adolescents and that the effects of culture are mediated by weight attributions and thin idealization. Participants (N = 335; 181 female; M age = 14.83 years, SD = 1.57 years) completed measures of thin idealization and causal attributions and made generalizations from and attributions of stereotypical personality characteristics to obese figures. Not only did stereotypes differ between countries, but generalizations of negative characteristics from obese figures increased with age. In addition, American adolescents more firmly endorsed the 'thin ideal' and were more likely to attribute obesity to internal causes that Chinese adolescents. As anticipated, between-country differences in stereotyping were mediated by thin idealization and causal attributions. Findings are discussed in terms of the 'doctrine of the mean', social identity theory, and dual-process theories. Statement of Contribution The development of obesity stereotypes has been the subject of a number of recent studies. Although scarce, research on adolescents' obesity stereotypes indicates that the strength of these stereotypes increases with age and that these increases are mediated by thin idealization and causal attributions. The current research adds to this growing literature that differences between Chinese adolescents' and American adolescents' obesity stereotypes - in terms of the assignment of stereotypical traits to people with obesity and the generalization of negative traits from an individual person with obesity to people with obesity as a group - are mediated by thin idealization and attributions about obesity's causes. The research also indicates that (1) age differences in obesity stereotyping vary as a function of the method used to measure stereotypes, (2) Chinese adolescents are less likely than American adolescents to attribute obesity to characterological flaws, and (3) American adolescents idealize thinness more than Chinese adolescents., (© 2018 The British Psychological Society.)

Background: Childhood obesity is a worldwide health challenge and risk factor for adult life obesity, which predisposes to development of type 2 diabetes and cardiovascular diseases. However, also thinness in early life has been related to these diseases, especially if followed by fat gain. In European countries, susceptibility to cardio-metabolic diseases varies considerably between ethnic groups. We investigated ethnic differences in overweight and thinness in a multi-ethnic, population-based cohort of preschool children in Norway, and associations with maternal and early postnatal factors., Methods: Participants were children aged 4-5 years (n = 570) drawn from the population-based STORK Groruddalen cohort of healthy women and offspring followed from early pregnancy. Ethnic groups were: European (n = 298), South Asian (n = 154), and Middle East/North African (n = 118). Children's growth data were provided from routine visits at local Child Health Clinics. Weight status was defined by the International Obesity Task Force. Using multinomial logistic regression analysis, we explored ethnic differences in overweight and thinness, and associations with maternal-, pre, - and postnatal factors., Results: Children of Middle East/North African origin had higher prevalence of overweight (22.0%) compared to European (12.8%) children, and in adjusted logistic regression analysis almost the double risk (OR 1.98; 95%CI: 1.08-3.63). Prevalence was lower in children of South Asian origin (5.2%). Children with South Asian background had higher prevalence of thinness (26.0%) compared to ethnic Europeans (10.4%), and the double risk (OR 2.20; 95%CI: 1.25-3.87) in adjusted models. Applying newly suggested BMI adjustments in South Asian children, taking into account their relatively increased adiposity, markedly increased the prevalence of overweight, and decreased the prevalence of thinness in this subgroup. Birthweight and maternal prepregnant overweight were strongly, positively associated with overweight, and inversely associated with thinness. Lower maternal age was associated with overweight only., Conclusions: In a multi-ethnic cohort we found strikingly different patterns of overweight and thinness among children of different ethnic groups at age 4-5 years, and a strong association between maternal BMI and their children's weight status. More knowledge is needed on what characterizes and what promotes healthy growth patterns in multi-ethnic populations.

Background/objectives: While previous studies have documented racial/ethnic disparities in childhood obesity, less is known about when disparities emerge, how they evolve, and the most appropriate early childhood period for targeted interventions. We examined racial/ethnic differences in growth trajectories among US kindergarten-aged children followed from birth and identified sensitive periods at which disparities emerge., Subjects and Methods: This is a longitudinal study design using Early Childhood Longitudinal Study Birth Cohort data. We employed random effects growth curves to model trajectories of mean BMI z-scores by race/ethnicity and sex. To visualize sensitive periods for emergence of disparities, we used locally estimated smoothing spline curves to graph the relationship between age and BMI z-score within each racial group., Results: Unweighted baseline sample size included ~ 7200 children. Overall, 54.6% of children were white, 23.1% Hispanic, 15.7% African-American, 3.4% Asian, 2.8% American-Indian, and 0.4% Pacific-Islander. Mean BMI z-scores for Hispanic boys and American-Indian boys and girls were already significantly higher by 24 months than their white peers and remained higher through kindergarten entry. African-American and Asian children started with significantly lower birth-weights compared to whites, but Asian girls' growth trajectory remained slow, while African-American girls experienced steeper increases in BMI z-scores and ultimately overtook their white and Asian peers over time. By kindergarten entry, disparities were present across all racial/ethnic groups., Conclusion: Racial/ethnic disparities in US children's weight status and growth trajectories emerge at different ages for different racial groups, but they are generally well established by kindergarten age. Our findings indicate that interventions designed to prevent early childhood overweight/obesity should be implemented early in the life course.

The present study was carried out with parents of 520 healthy children between the ages of 2-12 and their parents who were referred to the diet polyclinic of a hospital in Ankara. The data were collected through personal interviews. The interviews included identifying the characteristics of the child and his/her parents, anthropometric measurements, questions investigating eating status, and the Children's Eating Behavior Questionnaire. According to the body mass index-Z scores, there were differences between subgroups of food responsiveness, emotional overeating, enjoyment of food, food fussiness, and slowness in eating. The gender-based desire to drink score was, on average, higher in boys. No gender-based differences were found in other subgroups, whereas the scores in the food fussiness and slowness in eating and emotional undereating were higher in the preschool group when analyzed by age. In conclusion, eating behaviors of overweight and obese children differ from those of normal and underweight children.

Background: Overweight is shown to track (= to maintain a relative position in a distribution) from childhood to adulthood, but is mostly studied in preobesogenic cohorts and in single ethnic groups. Little is known about tracking of thinness by ethnicity., Objectives: to determine (differences in) tracking of BMI (class) from 3 through 15 years and the prediction of BMI class at 13-15 years of age in contemporary Dutch, Turkish, Moroccan and South Asian children living in the Netherlands., Methods: Historical cohort of 7625 children, born 1994-1997, with 24,376 measurements of BMI. BMI z-score and BMI class was analysed using universal criteria. South Asian children were also assessed using ethnic specific BMI criteria. Diagnostic odds ratios (OR) and test properties were calculated to estimate the ability of BMI class at 3-4 years to predict BMI class at 13-15 years., Results: Tracking of thinness between 3 and 15 years was stronger than that of overweight, as indicated by a generally higher diagnostic OR. BMI trajectories between 3 and 15 years of age of thin, normal weight and overweight adolescents were, although significantly different, quite similarly shaped in children of Dutch, Turkish and Moroccan descent. The South Asian BMI trajectory deviated considerably from the other ethnic groups, but the differences disappeared when South Asian specific BMI criteria were applied. A substantial proportion of overweight developed between 5-10 years, after which less children shifted to other BMI classes. A total of 55-78% of children with overweight at 3-4 years retained their overweight at 13-15 years, and 10-20% of 3-4 year olds with thinness remained thin., Conclusions: In all ethnic groups, overweight and especially thinness highly tracked into adolescence. South Asian children differed from the other ethnic groups when universal BMI criteria were applied, but with South Asian specific BMI criteria tracking patterns became more concordant.

No previous studies have examined the interaction between body mass index (BMI) and race/ethnicity with the risk of atrial fibrillation (AF). We retrospectively followed 48,323 persons free of AF (43% Hispanic, 37% black, and 20% white; median age 60 years) for subsequent incident AF (ascertained from electrocardiograms). BMI categories included very severely underweight (BMI <15 kg/m 2 ), severely underweight (BMI 15.1 to 15.9 kg/m 2 ), underweight (BMI 16 to 18.4 kg/m 2 ), normal (BMI 18.5 to 24.9 kg/m 2 ), overweight (BMI 25.0 to 29.9 kg/m 2 ), moderately obese (BMI 30 to 34.9 kg/m 2 ), severely obese (BMI 35 to 39.9 kg/m 2 ), and very severely obese (BMI >40 kg/m 2 ). Cox regression analysis controlled for baseline covariates: heart failure, gender, age, treatment for hypertension, diabetes, PR length, systolic blood pressure, left ventricular hypertrophy, socioeconomic status, use of β blockers, calcium channel blockers, and digoxin. Over a follow-up of 13 years, 4,744 AF cases occurred. BMI in units of 10 was associated with the development of AF (adjusted hazard ratio 1.088, 95% confidence interval 1.048 to 1.130, p <0.01). When stratified by race/ethnicity, non-Hispanic whites compared with blacks and Hispanics had a higher risk of developing AF, noted in those whom BMI classes were overweight to severely obese. In conclusion, our study demonstrates that there exists a relation between obesity and race/ethnicity for the development of AF. Non-Hispanic whites had a higher risk of developing AF compared with blacks and Hispanics., (Copyright © 2018. Published by Elsevier Inc.)

Obesity-driven Type 2 diabetes (T2D) is a systemic inflammatory condition associated with cardiovascular disease. However, plasma cytokines and tissue inflammation that discriminate T2D risk in African American women with obese phenotypes are not well understood. We analyzed 64 circulating cytokines and chemokines in plasma of 120 African American women enrolled in the Black Women's Health Study. We used regression analysis to identify cytokines and chemokines associated with obesity, co-morbid T2D and hypertension, and compared results to obese women without these co-morbidities, as well as to lean women without the co-morbidities. We then used hierarchical clustering to generate inflammation signatures by combining the effects of identified cytokines and chemokines and summarized the signatures using an inflammation score. The analyses revealed six distinct signatures of sixteen cytokines/chemokines (P = 0.05) that differed significantly by prevalence of T2D (P = 0.004), obesity (P = 0.0231) and overall inflammation score (P < E-12). Signatures were validated in two independent cohorts of African American women with obesity: thirty nine subjects with no metabolic complications or with T2D and hypertension; and thirteen breast reduction surgical patients. The signatures in the validation cohorts closely resembled the distributions in the discovery cohort. We find that blood-based cytokine profiles usefully associate inflammation with T2D risks in vulnerable subjects, and should be combined with metabolism and obesity counselling for personalized risk assessment.

Background: Little is known regarding the nutritional burden in Chinese ethnic minority children. This study aimed to investigate the epidemiological characteristics of excess body weight and underweight for 26 ethnic groups., Methods: Data on 80,821 participants aged 7-18 years across 26 minorities, with completed records from a large national cross-sectional survey, were obtained from Chinese National Survey on Students' Constitution and Health (CNSSCH) in 2014. Excess body weight, underweight and their components were classified according to Chinese national BMI references., Results: The overall prevalence of excess body weight and underweight among ethnic groups were 12.0% and 14.5%, in which 4.4% and 4.1% of the participants were classified as obese and severe wasting, respectively. Compared with girls, boys showed a higher prevalence of underweight, severe wasting and obesity, but a lower prevalence of excess body weight (P < 0.05). Among 26 ethnic groups, Koreans had the highest prevalence of excess body weight (30.4%), while Bouyeis showed the highest prevalence of underweight (25.7%). The ethnic minority groups with high prevalence of excess body weight and underweight were more likely to show high burden of obesity and severe wasting, respectively. However, it is not the case for some groups, such as Miaos and Shuis., Conclusions: A worrying dual burden of excess body weight and underweight was recognized in Chinese ethnic minority children. Since various characteristics were found among different minorities, the ethnic-specific effort is warranted to improve their nutritional status.

Purpose: Essential fatty acids play a critical role in the growth and development of infants, but little is known about the fatty acid status of populations in low-income countries. The objective was to describe the fatty acid composition of red blood cells (RBC) in breastfeed Nepali infants and a subsample of their mothers and to identify the main sources of fatty acids in the mother's diet, as well as the fatty acid composition of breast milk., Methods: RBC fatty acid composition was analyzed in a random sample of 303 infants and 72 mother, along with 68 breastmilk samples. Fatty acid profiles of the most important dietary fat sources were analyzed. Information on mother's diet and intake of fat was collected by three 24-h dietary recalls., Results: In infant RBC's, docosahexaenoic acid (DHA) was the main n-3 fatty acid, and arachidonic acid (AA) was the major n-6 fatty acid. Total n-6 PUFA was three times higher than total n-3 PUFA. Height-for-age (HAZ) was positively associated with DHA status and AA status in multivariable models. The concentration of all fatty acids was higher in children, compared to mothers, except Total n-6 PUFA and Linoleic acid (LA) where no differences were found. The mother's energy intake from fat was 13% and cooking oil (sesame, mustard, soybean or sunflower oil) contributed 52% of the fat intake., Conclusions: RBC-DHA levels in both infants and mother was unexpected high taking into account few dietary DHA sources and the low DHA concentrations in breastmilk.

While research consistently supports the negative impact of thinness pressures on body image, this work has primarily utilized White samples in the United States, limiting generalizability to other ethnicities. Further, limited research has examined ethnic differences in thinness pressures from distinct sociocultural influences. This study examined distinct sources of thinness pressures in 598 White, 135 Black, and 131 Hispanic college women in the United States. Mean levels of thinness pressures significantly differed across ethnicity, with Black women generally reporting the lowest levels of each pressure. Additionally, distinct sources of thinness pressures were more highly related to negative outcomes within ethnic groups. For White women, each source was salient for disordered eating. For Black women, family pressure was particularly salient for appearance evaluation. For Hispanic women, family pressure was particularly salient for disordered eating and appearance evaluation. Findings suggest possible ethnic differences in the relative salience of some pressures over others., (Copyright © 2017 Elsevier Ltd. All rights reserved.)

Early childhood development plays a key role in a child's future health, educational success, and economic status. However, suboptimal early development remains a global challenge. This study examines the influences of quality of the home learning environment (HOME) and child stunting in the first year of life on child development. We used data collected from a randomized controlled trial of preconceptional micronutrient supplementation in Vietnam (n = 1,458). The Bayley Scales of Infant Development-III were used to assess cognition, language, and motor development domains at 2 years. At 1 year, 14% of children were stunted, and 15%, 58%, and 28% of children lived in poor, medium, and high HOME environments, respectively. In multivariate generalized linear regression models, living in a high HOME environment was significantly associated with higher scores (0.10 to 0.13 SD) in each of the developmental domains. Stunted children scored significantly lower for cognitive, language, and motor development (-0.11 to -0.18), compared to nonstunted children. The negative associations between stunting on development were modified by HOME; the associations were strong among children living in homes with a poor learning environment whereas they were nonsignificant for those living in high-quality learning environments. In conclusion, child stunting the first year of life was negatively associated with child development at 2 years among children in Vietnam, but a high-quality HOME appeared to attenuate these associations. Early interventions aimed at improving early child growth as well as providing a stimulating home environment are critical to ensure optimal child development., (© 2017 John Wiley & Sons Ltd.)

Socioeconomic status (SES) is associated with childhood anthropometry, but little is known about how it is associated with tissue growth and body composition. To investigate this, we looked at components of SES at birth with growth in early and mid-childhood, and body composition in a longitudinal study in Nepal. The exposure variables (material assets, land ownership, and maternal education) were quantified from questionnaire data before birth. Anthropometry data at birth, 2.5 and 8.5 years, were normalized using WHO reference ranges and conditional growth calculated. Associations with child growth and body composition were explored using multiple regression analysis. Complete anthropometry data were available for 793 children. There was a positive association between SES and height-for-age and weight-for-age, and a reduction in odds of stunting and underweight for each increase in rank of SES variable. Associations tended to be significant when moving from the lower to the upper asset score, from none to secondary education, and no land to >30 dhur (~500 m 2 ). The strongest associations were for maternal secondary education, showing an increase of 0.6-0.7 z scores in height-for-age and weight-for-age at 2.5 and 8.5 years and 0.3 kg/m 2 in fat and lean mass compared to no education. There was a positive association with conditional growth in the highest asset score group and secondary maternal education, and generally no association with land ownership. Our results show that SES at birth is important for the growth of children, with a greater association with fat mass. The greatest influence was maternal secondary education., (© 2017 The Authors Maternal & Child Nutrition Published by John Wiley & Sons Ltd.)

Introduction It has been established that underweight women with low gestational weight gain (GWG) are at a higher risk of having Small for Gestational Age (SGA) newborns. However, the association remains poorly studied in Middle Eastern societies exhibiting different ethnic groups, genetic predisposing factors along with differences in nutritional food intake during pregnancy. The aim of this study is to assess the risk of having a SGA newborn among underweight and normal weight BMI women while studying the role of GWG in this association. Methods This is a retrospective cross-sectional study of 62,351 singleton pregnancies from the National Collaborative Perinatal Neonatal Network between 2001 and 2009 from 27 hospitals across Lebanon. Women who had underweight and normal pre-pregnancy BMI were included. Results A total of 8.6% newborns were SGA and 6.6% of women were underweight. Among women with normal and underweight pre-pregnancy BMI, 8.6 and 12.4% had SGA births respectively. Overall, the adjusted OR of having SGA newborns was significantly higher among underweight women (OR = 1.448; 95%CI = 1.287-1.630) compared to normal pre-pregnancy BMI. Below normal weight gain significantly increased the odds of SGA for both normal and underweight pre-pregnancy BMI women, with adjusted ORs of 1.535 (95% CI = 1.418-1.661) and 1.970 (95%CI = 1.515-2.560) respectively. Discussion Higher risks of SGA newborns in underweight and normal BMI women with low GWG were observed. In addition, normal weight gain couldn't protect underweight women of having risk for SGA newborns. Hence, all pregnant women should be encouraged to maintain healthy BMI before pregnancy and attain adequate GWG.

Despite the importance of the nutritional status and food systems of Indigenous Peoples, the subject has received very little attention, especially in North-East India. Therefore, a community-based cross-sectional descriptive study was carried out among Chakhesang mothers with children under 5 years of age to evaluate their nutritional status and prevalence of chronic diseases in the context of their dietary habits. From 558 households (HHs), 661 children and 540 mothers were covered using standard anthropometric measurements as well as blood collection for haemoglobin and vitamin A. Data were collected from mothers on HH socio-demographic particulars and infant and young child feeding practices. The results showed that the prevalence of underweight, stunting, and wasting among children <5 years of age was 14%, 22%, and 7%, respectively. The prevalence of anaemia and vitamin A deficiency was 26% and 33% among children <5 years, whereas it was 33% and 26%, respectively, among mothers. Hypertension was observed in 16% of women, whereas diabetes was seen in 0.8%. Approximately 35% and 24% of HHs suffered mild or moderate food insecurity, respectively, which was associated with literacy of the parents, per capita income, and family size. Utilization of the rich agrobiodiversity and wild foods by the Chakhesangs appears to be a strong reason for their better nutritional and health status as compared to the rest of India. Therefore, this Indigenous knowledge and food system must be documented and kept vital, especially in policies and intervention programmes addressing food and nutrition security among the Chakhesangs., (© 2018 John Wiley & Sons Ltd.)

A community-based cross-sectional study was carried out with 603 children ages 5 and under and 500 of their mothers from 510 households to examine the prevalence of undernutrition and chronic diseases among the Khasis of North-East India. Anthropometric measurements including Mid-Upper Arm Circumference, height, and weight were taken. Dry blood spots to estimate haemoglobin and vitamin A were collected from children and women separately by finger prick. Mothers provided data about household socio-demographic particulars and infant and young child feeding practices. The prevalence in children of underweight was 31%, stunting was 57%, and wasting was 10%. Undernutrition was higher among boys as compared to girls. Nutrient intakes were below recommended levels. The prevalence of anaemia among children ages 1 to 5 years old was 68%, and vitamin A deficiency was 59%, and they were 83% and 48%, respectively, among women. Hypertension was observed in 15% of women, whereas diabetes was less than 1%. Only about 20% of households were food secure, and this was associated with parental literacy, per capita income, and family size. Undernutrition was unacceptably high among the Khasis despite rich food biodiversity. Proper implementation of nutritional intervention programs such as Integrated Child Development Services, Mid Day Meal, and the Public Distribution System will improve the nutrient intake and nutritional status of the population. Additionally, preservation of forest lands and products paired with judicious use of the rich food biodiversity available will promote dietary diversity and ultimately better nutrition and health., (© 2018 John Wiley & Sons Ltd.)

Objectives: Soluble DPP4 (sDPP4) is a novel adipokine that degrades glucagon-like peptide (GLP-1). We evaluated the fasting serum levels of active GLP-1 and sDPP4 in obese, overweight and normal weight subjects to assess the association between sDPP4 levels, active GLP-1 levels and insulin resistance in obese subjects., Methods: The study involved 235 Malaysian subjects who were randomly selected (66 normal weight subjects, 97 overweight, 59 obese subjects, and 13 subjects who were underweight). Serum sDPP4 and active GLP-1 levels were examined by enzyme-linked immunosorbent assay (ELISA). Also, body mass index kg/m 2 (BMI), lipid profiles, insulin and glucose levels were evaluated. Insulin resistance (IR) was estimated via the homeostasis model assessment for insulin resistance (HOMA-IR)., Results: Serum sDPP4 levels were significantly higher in obese subjects compared to normal weight subjects (p=0.034), whereas serum levels of active GLP-1 were lower (p=0.021). In obese subjects, sDPP4 levels correlated negatively with active GLP-1 levels (r 2 =-0.326, p=0.015). Furthermore, linear regression showed that sDPP4 levels were positively associated with insulin resistance (B=82.28, p=0.023) in obese subjects., Conclusion: Elevated serum sDPP4 levels and reduced GLP-1 levels were observed in obese subjects. In addition, sDPP4 levels correlated negatively with active GLP-1 levels but was positively associated with insulin resistance. This finding provides evidence that sDPP4 and GLP-1 may play an important role in the pathogenesis of obesity, suggesting that sDPP4 may be valuable as an early marker for the augmented risk of obesity and insulin resistance., (Copyright © 2017 The Canadian Society of Clinical Chemists.

Objective: Undernutrition and non-communicable disease (NCD) are important public health issues in India, yet their relationship with dietary patterns is poorly understood. The current study identified distinct dietary patterns and their association with micronutrient undernutrition (Ca, Fe, Zn) and NCD risk factors (underweight, obesity, waist:hip ratio, hypertension, total:HDL cholesterol, diabetes)., Design: Data were from the cross-sectional Indian Migration Study, including semi-quantitative FFQ. Distinct dietary patterns were identified using finite mixture modelling; associations with NCD risk factors were assessed using mixed-effects logistic regression models., Setting: India., Subjects: Migrant factory workers, their rural-dwelling siblings and urban non-migrants. Participants (7067 adults) resided mainly in Karnataka, Andhra Pradesh, Maharashtra and Uttar Pradesh., Results: Five distinct, regionally distributed, dietary patterns were identified, with rice-based patterns in the south and wheat-based patterns in the north-west. A rice-based pattern characterised by low energy consumption and dietary diversity ('Rice & low diversity') was consumed predominantly by adults with little formal education in rural settings, while a rice-based pattern with high fruit consumption ('Rice & fruit') was consumed by more educated adults in urban settings. Dietary patterns met WHO macronutrient recommendations, but some had low micronutrient contents. Dietary pattern membership was associated with several NCD risk factors., Conclusions: Five distinct dietary patterns were identified, supporting sub-national assessments of the implications of dietary patterns for various health, food system or environment outcomes.

Background: There is very limited data on malnutrition of preschool children in Kosovo. The main objective of the study is to provide a nutritional status profile of preschool children attending kindergartens in Kosovo., Methods: Cross-sectional study of children aged 12-59 months (n = 352 children) and children aged 60-83 months (n = 134) enrolled in public and private kindergartens of Kosovo. Anthropometric measurements used for this study are weight and height of the preschoolers (12-83 months). A measuring board was used for measuring the length/height of children younger than 2 years, while digital weight and height scale Seca 763 was used for measuring of preschool children taller than 110 and Seca 213 was used for measuring the height for children who were shorter than 110 cm. Statistical analyses of underweight and overweight trends across sex and age groups as well as between children from public and private kindergartens were carried out. Qualitative variables were tested with a chi-square test. The differences between groups were assessed with a Student t test for normally distributed variables and a Mann-Whitney test for abnormally distributed numerical variables., Results: The mean z-scores for weight-for-age, height-for-age, weight-for-height, and BMI-for-age largely fell within 0.0 and 1.0. The percentage of stunted children is 3%, whereas child wasting is 1.9%. The overall percentage of obese children is 2.3%; furthermore, 8.9% are overweight and 27.3% have a possible risk of being overweight., Conclusions: The incidence of children underweight is slightly decreasing. The prevalence of overweight and obese children in sample chosen is evident.

Childhood obesity is prevalent among ethnic minorities in the UK but little is known about parent feeding practices in these populations. We administered questionnaires assessing parental feeding behaviors and perceptions and concerns relating to child weight to White British (n = 271), South Asian (n = 59), and Black Afro-Caribbean (n = 42) parents of UK 3-5 year-olds. Child BMI z-scores were determined from measured heights and weights. South Asian and Black Afro-Caribbean parents exhibited greater pressure to eat than White British parents. Black Afro-Caribbean parents additionally scored higher on instrumental feeding and lower on monitoring, while South Asian parents scored higher on emotional feeding. Black Afro-Caribbean parents reported the greatest concern about both child overweight and underweight. Ethnic differences were unchanged by controlling for perceptions and concerns relating to child weight, or for actual BMI z, parent education, or household income. Exploratory analyses suggested some evidence for sex differences within ethnic groups. For example, South Asian parents of daughters scored higher than White British parents of daughters on emotional feeding, with no ethnic differences apparent for parents of sons. Our findings support considering variation in parent feeding behaviors and weight-related attitudes by parental ethnicity and child sex when developing obesity interventions., (Copyright © 2017 Elsevier Ltd.

Background: Substantial evidence is emerging on the coexistence of double burden of malnutrition on adolescents of low-income countries, shaping the health challenges of the upcoming adult generation for the worst. Whether nutritional status markers of adolescents in the cash crop setting are on par with economic gains remains uncertain. Thus, we investigated the nutritional outcomes of adolescents and their determinants in coffee farming households., Methods: The survey was carried out in 3 top coffee-producing districts of Jimma Zone, Ethiopia. Five hundred fifty mothers/caregivers and their respective adolescents were selected using multistage random sampling. Anthropometric data were converted into height-for-age and body-mass-index-for-age Z scores using WHO Anthroplus software and analyzed by SPSS for windows., Results: Prevalence of thinness, stunting, and overweight/obesity were 11.6%, 15.6%, and 7.1%, respectively. The odds of stunting among adolescents in households in the lowest wealth tertile was nearly 6-fold higher compared to the highest tertile (adjusted odds ratio [AOR] = 5.6 [2.6-12]). Conversely, the odds of overweight/obesity was higher among adolescents in the households in the middle wealth tertile (AOR = 2.72 [1.08-6.86]) compared to the highest tertile. Adolescents living in households with low-dependent age-groups were more than twice likely to be overweight/obese (AOR = 2.58 [1.06-6.24])., Conclusion: The current study revealed the presence of substantial dual burden of malnutrition. In such a setting, it is critical to draw a fine line and trade-off for eliminating morbidity and mortality of undernutrition, without triggering the risk of overweight/obesity.

The purpose of this study was to evaluate the relationship between body mass index and motor competence in Santal children 5-12 years old. A total of 816 Santal children were studied. Children's adiposity status was assessed by body mass index (BMI) for age z-score based on World Health Organization reference data. Motor competence was measured using the Bruininks-Oseretsky Test of Motor Competence (BOT-2). There was no significant difference in mean BMI z-score between Santal boys (0.13 ± 0.07) and girls (-0.14 ± 0.07). Healthy weight (HW) children scored higher (p < .05) in some individual motor subtests (bilateral competence, balance, running speed and agility, upper limb competence, and strength) and in total BOT-2 score (p < .05) compared with scores for underweight (UW) and overweight (OW) children. Nonlinear regression analysis showed that BMI is a significant independent predictor of motor competence (p < .01). Motor competence showed a curvilinear relationship with BMI-z-score, with the lowest point motor scores in strength and upper limb competence (p < .05) for both UW and OW children compared to HW children who scored highest. The results also indicated that gross motor skills, but not fine motor skills, were poorer among children who were UW or OW compared with HW children.

Purpose: To quantify the relationship between pregnancy weight gain with early and late preterm birth and evaluate whether associations differed between non-Hispanic (NH) black and NH white women., Methods: We analyzed a retrospective cohort of all live births to NH black and NH white women in the United States 2011-2015 (n = 10,714,983). We used weight gain z-scores in multiple logistic regression models stratified by prepregnancy body mass index (BMI) and race to calculate population attributable risk (PAR) percentages for the contribution of high and low pregnancy weight gain to early and late preterm birth., Results: Pregnancy weight gain was related to early and late preterm birth, but associations varied by BMI and race. For early preterm birth, the PAR percentage for high pregnancy weight gain ranged from 8 to 10% in NH black women and from 6 to 8% in NH white women. There was little evidence of racial differences in late preterm birth: PAR percentages ranged from 2 to 7% in NH black women and from 3 to 7% in NH white women., Conclusions: Moderate gestational weight gain is associated with lower rate of preterm birth, with greatest reductions for early preterm birth in NH black women., (Copyright © 2017 Elsevier Inc.

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

This study aimed to evaluate dietary nutrient intake among Chinese pregnant women by comparison with Chinese Dietary Reference Intakes (DRIs) and to explore the association between dietary nutrients and preterm birth. A case-control design was conducted in Beijing with 130 preterm delivery mothers in case group and 381 term delivery mothers in control group. Information on mothers' diet was collected using a food frequency questionnaire, and nutrients and energy intakes were subsequently calculated based on DRIs. Multivariate analysis of variance was used to compare the differences between term and preterm groups in relation to dietary nutrients. Dietary nutrient intakes were imbalanced in both groups compared with Chinese DRIs. Preterm delivery mothers had a lower level of fat and vitamin E intake than term delivery mothers (p < 0.05). Multivariate analysis showed lower vitamin E intake in preterm delivery mothers with a prepregnancy BMI < 18.5 kg/m2 (p < 0.05) and higher carbohydrate intake in preterm delivery mothers with prepregnancy BMI ≥ 24 kg/m2 (p < 0.05). An imbalanced diet in both groups and low level of dietary intakes of fat and vitamin E in preterm group suggest health education measures should be taken to improve the dietary quality of pregnant women, especially for those with an abnormal prepregnancy BMI.

Aims: Overweight and obesity are established major risk factors for type 2 diabetes, and major public health concerns in China. This study aims to assess the economic burden associated with overweight and obesity in the Chinese population ages 45 and older., Methods: The Chinese Health and Retirement Longitudinal Study (CHARLS) in 2011 included 13,323 respondents of ages 45 and older living in 450 rural and urban communities across China. Demographic information, height, weight, direct health care costs for outpatient visits, hospitalization, and medications for self-care were extracted from the CHARLS database. Health Care costs were calculated in 2011 Chinese currency. The body mass index (BMI) was used to categorize underweight, normal weight, overweight, and obese populations. Descriptive analyses and a two-part regression model were performed to investigate the association of BMI with health care costs. To account for non-normality of the cost data, we applied a non-parametric bootstrap approach using the percentile method to estimate the 95% confidence intervals (95% CIs)., Results: Overweight and obese groups had significantly higher total direct health care costs (RMB 2246.4, RMB 2050.7, respectively) as compared with the normal-weight group (RMB 1886.0). When controlling for demographic characteristics, overweight and obese adults were 15.0% and 35.9% more likely to incur total health care costs, and obese individuals had 14.2% higher total health care costs compared with the normal-weight group., Conclusions: Compared with the normal-weight counterparts, the annual total direct health care costs were significantly higher among obese adults in China., (Copyright © 2016 Elsevier Inc.

Aims: To investigate the association between body-mass index and mortality in Chinese adults T2DM., Methods: 11,449 participants of Kailuan Study with T2DM were included in this prospective cohort study. All-cause mortality was calculated using Kaplan-Meier analysis. Cox proportional hazards analysis was used to estimate the association between BMI and mortality., Results: During a mean follow-up period of 7.25±1.42years, 1254 deaths occurred. The number of deaths of the underweight, normal weight, overweight, and obese group was 23, 389, 557, and 285; the corresponding mortality was 25.0%, 13.4%, 10.3%, and 9.4%, respectively. The obese group had the lowest all-cause mortality rate (log-rank chi-square=48.430, P<0.001). After adjusting for age, sex, fasting blood glucose, smoking status, systolic blood pressure, history of hypertension, stroke, cancer and myocardial infarction, compared with the normal weight group, Multivariate Cox proportional hazard regression analysis showed that HR (95% CI) of all-cause mortality in the underweight, overweight, and obese group was 1.497 (0.962, 2.330), 0.833 (0.728, 0.952), and 0.809 (0.690, 0.949). After stratifying for age tertiles, this trend remained., Conclusions: In T2DM patients in north China, the risk for all-cause mortality was lower in the overweight and the obese groups than those in the normal weight and the underweight groups., (Copyright © 2017 Elsevier Inc.

Wasting and underweight reflect poor nutrition, which in children leads to retarded growth. The aim of this study is to determine the factors associated with wasting and underweight among children aged 0-59 months in Nigeria. A sample of 24,529 children aged 0-59 months from the 2013 Nigeria Demographic and Health Survey (NDHS) was used. Multilevel logistic regression analysis that adjusted for cluster and survey weights was used to identify significant factors associated with wasting/severe wasting and underweight/severe underweight. The prevalence of wasting was 18% (95% Confidence Interval (CI): 17.1, 19.7) and severe wasting 9% (95% CI: 7.9, 9.8). The prevalence of underweight was 29% (95% CI: 27.1, 30.5) and severe underweight 12% (95% CI: 10.6, 12.9). Multivariable analysis revealed that the most consistent factors associated with wasting/severe wasting and underweight/severe underweight are: geopolitical zone (North East, North West and North Central), perceived birth size (small and average), sex of child (male), place/mode of delivery (home delivery and non-caesarean) and a contraction of fever in the two weeks prior to the survey. In order to meet the WHO's global nutrition target for 2025, interventions aimed at improving maternal health and access to health care services for children especially in the northern geopolitical zones of Nigeria are urgently needed., Competing Interests: The authors declare no conflict of interest.

Background: Adolescent obesity is prevalent in Pacific region ethnic groups (European, Melanesian and Polynesian) living in both urban and rural areas. Although body perception is an important factor of weight gain or loss, little is known about the body self-perceptions of Pacific region adolescents. This study therefore evaluated adolescent perceptions of body weight according to ethnicity (European, Melanesian or Polynesian), socioeconomic status (low, intermediate or high) and living area (rural or urban) in New Caledonia., Methods: Sociodemographic and anthropomorphic data from 737 adolescents (351 boys and 386 girls) with ages ranging from 11 to 16 years were collected and analysed. The International Obesity Task Force (IOTF) standards were used to define weight status as normal-weight, underweight or overweight/obese. Weight perception was assessed from detailed questionnaires, with adolescents rating their own weight with the following descriptors: 'about the right weight', 'too heavy', or 'too light'., Results: Results showed that only 8.5% of normal-weight adolescents (7% boys and 10% girls) identifying themselves as 'too heavy'. Normal-weight Melanesian adolescents were less likely than their European counterparts to assess themselves as too heavy (OR = 0.357). However, half the overweight/obese adolescents underestimated their weight status (53% boys and 48% girls). Weight misperception was associated with ethnicity, socioeconomic status and living area, with gender-specific differences., Conclusions: The results of this study suggest that these sociodemographic factors should be taken into account when designing public health policies and health education school programmes in New Caledonia and, more broadly, the Pacific region.

Objective: This study aimed to reveal the 1) awareness, 2) improvements of a health-promoting lifestyle on women with unexplained infertility having at least one of the risk factors that have been indicated to negatively affect fertility (smoking, body mass index lower than 18.5kg/m 2 and more than 25kg/m 2 , over-exercising or not exercising at all, alcohol consumption, caffeine consumption of more than 300mg/day, and high levels of stress) by means of health-promoting lifestyle education, 3) the effect of this improvement on the result of assisted-reproduction treatment in terms of clinical pregnancy., Study Design: 64 women diagnosed with unexplained infertility were divided into a group receiving Health-Promoting Lifestyle (HPL) education and a control group. 1) Risk Factors Questionnaire (BMI, Smoking, Alcohol, Stress, Exercise, Caffeine), 2) Depression, Anxiety and Stress Scale, 3) Health-Promoting Lifestyle Profile II. The health promoting lifestyle was given to the education group. The Risk Factors Questionnaire; Depression, Anxiety, Stress Scale and Healthcare-Promoting Lifestyle Profile II were also administered after the first-second-third month of education but before ART treatment., Results: A statistically significant decrease was found in the average levels of four variables as; BMI (p<0.001)-stress (p<0.001)-caffeine consumption (p<0.001)-lower exercise levels (p<0.001). Moreover, the total number of risk factors that females had between the first and third interview decreased significantly. Clinical pregnancy rate after ART was 12 (46.1%) and 5 (19.2%) in education and control group consequently (p=0.02)., Conclusion: Health-promoting lifestyle education was found to be effective in reducing the lifestyle risk factors for infertility and increasing the success rates of assisted reproduction treatment by correcting these risk factors., (Copyright © 2016 Elsevier Ireland Ltd.

The relationship between body image, depression, food addiction and body mass index (BMI) and differences in these variables due to gender and field of education have not been studied extensively. This study was conducted on a total of 793 university students (20.19 ± 1.90 years). The Beck Depression Inventory, Yale Food Addiction, and Body Image Scale were used. It was determined that body image scores of females and individuals enrolled in health sciences programs were lower compared to those of males and those enrolled in the social sciences. There was a negative relationship between body image and depression and food addiction scores. There was a positive relationship between food addiction and depression scores, in addition to a positive relationship between food addiction and BMI.

Background: Both high and low prepregnancy body mass index (BMI) has been associated with small for gestational age births (SGA; birthweight below the population specific 10th centile for the gestational age), but results remain inconsistent. We examined the association between maternal BMI and SGA, and evaluated if the associations were modified by preterm birth (being born prior to 37 weeks) status., Methods: A population-based cohort study was conducted in Wuhan, China from June 2011, to June 2013. Women who delivered a non-malformed livebirth (n = 76 695) were included using the Wuhan Maternal and Child Health Management Information System. Log-binomial regression models were used to analyse the associations between prepregnancy BMI, categorized using thresholds adapted to the Chinese population, and SGA. Stratified analyses were used to examine the relationship of prepregnancy BMI to preterm-SGA and term-SGA., Results: Of the 76 695 live births, 3058 (4.0%) were delivered preterm. For babies born at term, prepregnancy underweight (<18.5 kg/m 2 ) was associated with an increased risk of SGA, the adjusted risk ratio (RR) was 1.41 (95% confidence interval (CI) 1.33, 1.49), whereas, being overweight (24.0-27.9 kg/m 2 ) was associated with a decreased risk (RR 0.84, 95% CI 0.74, 0.94). For babies born preterm, prepregnancy underweight was not associated with risk of SGA, but being overweight was associated with an increased risk (RR 1.57, 95% CI 1.04, 2.35)., Conclusions: These data suggest that the association of overweight and underweight prepregnancy BMI and SGA differs depending on whether the baby is full term or preterm., (© 2016 John Wiley & Sons Ltd.)

Objective: To estimate food intake changes from pre-conception to gestational period according to the degree of food processing., Methods: Prospective cohort conducted in a public health care center in Rio de Janeiro with Brazilian pregnant women (n = 189). A food frequency questionnaire was applied at the first (5(th)-13(th)) and third (30(th)-36(th)) gestational trimesters. The food items were classified according to characteristics of food processing in four groups: unprocessed/minimally processed foods; sugar/fat; processed foods and ultra-processed foods. The variation of food intake according to the degree of processing between the pre-conception and gestational period was compared using paired Student's t-test. Linear regression models were performed to estimate the association of mother's characteristics on the variation of food group contribution to the total energy intake between periods., Results: Total energy intake was 2415 (SD = 813) in the pre-conception and 2379 (750) kcal in the gestational period. We excluded women who had implausible total energy intake (<600 and >6000 kcal/day). The contribution of unprocessed/minimally processed food group to total energy intake during pregnancy when compared to the pre-conception period was higher [50.5 (14.1) vs. 48.8 (12.4), p-value = 0.048], while the caloric share of ultra-processed food group was lower [41.3 (14.6) vs. 43.1 (12.5), p-value = 0.032]. We observed a negative association of age (p-value = 0.009) and a positive association of pre-pregnancy BMI (p-value = 0.060) with the variation of ultra-processed food intake., Conclusions: Ultra-processed food intake decreased, while minimally/unprocessed food intake slightly increased from the pre-conception to gestational period. These results indicate potential for a larger improvement in the women's diet quality and that nutritional counseling interventions in pregnant women are still needed., (Copyright © 2016 Elsevier Ltd.

Objective: To investigate the interactions between low parental warmth and monitoring at age 13-14 years and disordered eating attitudes and behaviours at age 15-16 years., Method: Data on 1300 (667 females) adolescents and their parents were drawn from The Australian Temperament Project (ATP), a 30 year (15 wave) population based longitudinal study of social-emotional development. Parent participants completed surveys on parenting practices in late childhood, and adolescent participants reported disordered eating using the drive for thinness and bulimia subscales of the Eating Disorder Inventory (EDI) and an additional body dissatisfaction scale. Interaction was examined on the additive scale by estimating super-additive risk; i.e., risk in excess of the sum of individual risks., Results: For boys, neither parental warmth or monitoring, nor their interaction, was related to disordered eating. For girls, low parental warmth (alone) was associated with bulimic behaviours. In contrast, exposure to both low monitoring and warmth was associated with ∼3½-fold, ∼4-fold and ∼5-fold increases in the odds of reporting body dissatisfaction, drive for thinness and bulimia, respectively. For body dissatisfaction and drive for thinness, risk associated with joint exposure exceeded the sum of individual risks, suggesting an additive interaction between parenting styles., Conclusion: Further investment in family-level interventions that focus on promoting parental monitoring behaviour and a warm parent-child relationship remain important strategies for preventing a range of disordered eating behaviours in adolescents., (Copyright © 2016 Elsevier Ltd.

Background: Little is known about the secular trends in age at spermarche among boys, and the association between body mass index (BMI) and male puberty is controversial., Objective: This study aimed to estimate the trend in age at spermarche in China and explore the association of spermarche with BMI., Methods: We used four cross-sectional Chinese National Surveys on Students' Constitution and Health (CNSSCH; 1995, 2000, 2005 and 2010). Median age at spermarche was determined using probit analysis. Logistic regression was used to assess the association of spermarche with BMI., Results: Age at spermarche among Chinese boys dropped from 14.57 to 14.03 years from 1995 to 2010 with a decrease of 4.3 months per decade. Boys with BMI-for-age z-score lower than -2 had the latest age at spermarche. A higher BMI or BMI-for-age z-score was associated with an increased likelihood of having reached spermarche, and this association was consistently observed at all survey points., Conclusion: This study provides important evidence of a secular trend of earlier age at spermarche over the past 15 years in China, and this decrease was accompanied by a simultaneous increase in BMI. Strategies and interventions focusing on thinness may promote both their nutritional status and puberty development among Chinese boys., (© 2015 World Obesity.)

The aim of this study was to examine the association between household food insecurity and nutritional status among children aged 24-59 months in Haromaya District. Children (N = 453) aged 24-59 months were recruited in a community-based cross-sectional survey with a representative sample of households selected by a multistage sampling procedure in Haromaya District. Household Food Insecurity Access Scale and anthropometry were administered. Multinomial logistic regression models were applied to select variables that are candidate for multivariable model. The prevalences of stunting, underweight, and wasting among children aged 24-59 months were 61.1%, 28.1%, and 11.8%, respectively. The mean household food insecurity access scale score was 3.34, and 39.7% of households experienced some degree of food insecurity. By logistic regression analysis and after adjusting for the confounding factors, household food insecurity was significantly predictive of underweight (AOR = 2.48, CI = 1.17-5.24, p = .05) and chronic energy deficiency (AOR = 0.47, CI = 0.23-0.97, p = .04) and marginally significant for wasting (AOR = 0.53, CI = 0.27-1.03, p = .06). It is concluded that household food security improves child growth and nutritional status.

This cross-sectional study was conducted to determine household food security status and sociodemographic factors influencing it and to examine whether food insecurity of household is a risk factor for underweight, stunting, and thinness in primary school children of Sistan and Baluchestan Province in southeastern Iran. A sample of 610 students aged 7-11 years was selected by a multistage cluster random sampling method during December 2013-May 2014. Using U.S. Department of Agriculture Food Security questionnaire, 42.3% of households showed some degree of food insecurity. Food insecurity was positively associated with household size (p = .002) and number of children per household (p = .001) and negatively associated with mother's and father's education level (p = .005 and p = .042, respectively), father's occupation status, and household income (p < .0001). Children living in food insecure with severe hunger households were 10.13, 10.07, and 4.54 times as likely to be underweight, stunted, and thin, respectively, as counterparts from food secure households. The findings showed food insecurity was prevalent and associated with sociodemographic factors among households with schoolchildren in southeastern Iran. Nutritional status of children was also associated with food security status of their households.

The relationship between body mass index (BMI) and the prognosis of elderly patients with atrial fibrillation (AF) is unknown. We aimed to examine the association of body weight with the clinical outcomes among Japanese elderly patients with a history of documented AF. This observational study of AF patients from an outpatients clinic in Nagoya University Hospital included 413 patients ≥70 years old (99 obese: BMI ≥25 kg/m(2); 256 normal weight: BMI 18.5-24.9 kg/m(2); and 58 underweight patients: BMI <18.5 kg/m(2)). The mean age was 77.5 ± 5.6 years. During a mean follow-up of 19.0 months, all-cause death occurred in 23 patients (obese 1 %, normal weight 5.1 %, and underweight 16 %). The major adverse events including all-cause death, stroke or transient ischemic attack, heart failure requiring admission, and acute coronary syndrome were observed in 53 patients (obese 5.1 %, normal weight 13 %, and underweight 26 %). After adjusting for confounding factors, the underweight group had a significantly greater risk for all-cause death [hazard ratio (HR) 2.91, 95 % confidence interval (CI) 1.12-7.60, p = 0.029], and major adverse events (HR 2.45, 95 % CI 1.25-4.78, p = 0.009) than the normal weight group. In contrast, the obese group had a better prognosis in major adverse events compared with the normal weight group (HR 0.34, 95 % CI 0.13-0.89, p = 0.029). In conclusion, lower BMI was independently associated with poor outcomes among older AF patients. The association between obesity and better prognosis in elderly AF patients was also found.
