Association of number of children and birth order with body mass index in children and adolescents: The CASPIAN-V study

Abstract Background This study aimed to evaluate the association of the number of family children and birth order with later body mass index (BMI) in a pediatric population. Methods This cross-sectional nationwide study was conducted in the framework of the fifth survey of a national school-based surveillance program, entitled Childhood and Adolescence Surveillance and PreventIon of Adult Noncommunicable disease (CASPIAN-V) Study. Participants were 14,400 students, aged 7–18 years, who were selected by random cluster sampling from 30 provinces in Iran. Multinomial regression models were used to evaluate the odds ratio (OR) and 95% confidence intervals (95% CI) of the number of family children or the birth order for later excess weight. Results The first-born children had significantly higher OR for obesity, and the third-born children had higher OR of underweight compared to the first-born ones (OR 1.22, 95% CI 1.05–1.42). Moreover, children within the three-, four-, and five-child families had higher OR of underweight than those with one-child families (OR 0.88, 95% CI 0.77- 1). Conclusion The birth order and number of children were associated with underweight and overweight or obesity in children and adolescents. Future studies are necessary to assess the underlying determinants.

Introduction. To date, growth centiles of children and adolescents have not been created in Ukraine. Therefore, the aim of this study was to construct reference growth charts for height, weight, and body mass index (BMI) of Ukrainian school-aged children and to compare them with World Health Organization references from 2007 for children’s BMI. Material and Methods. Among the representative sample of 13,712 students (aged 7 to 18 years) who were included in this study, 6,582 (48%) were boys and 7,130 (52%) were girls. Assessments of height, body mass, and BMI of participants were performed. Reference charts were developed using LMS models within the ChartMaker lms program. Results. We present first growth references for height, weight, and body mass index for Ukrainian children and adolescents aged 7 to 18 years. The younger Ukrainian pediatric population (7-13 years) was heavier than population reported in the multiethnic WHO references, while the older (13-18 years) had lower body weight comparing to the same references from WHO. Conclusions. The constructed reference growth charts are a benchmark for following secular trends in Ukraine and are also an optimal clinical tool for health care. We recommend national implementation of the Ukrainian reference growth charts for anthropometric measurements.

We analyzed birth order differences in means and variances of height and body mass index (BMI) in monozygotic (MZ) and dizygotic (DZ) twins from infancy to old age. The data were derived from the international CODATwins database. The total number of height and BMI measures from 0.5 to 79.5 years of age was 397,466. As expected, first-born twins had greater birth weight than second-born twins. With respect to height, first-born twins were slightly taller than second-born twins in childhood. After adjusting the results for birth weight, the birth order differences decreased and were no longer statistically significant. First-born twins had greater BMI than the second-born twins over childhood and adolescence. After adjusting the results for birth weight, birth order was still associated with BMI until 12 years of age. No interaction effect between birth order and zygosity was found. Only limited evidence was found that birth order influenced variances of height or BMI. The results were similar among boys and girls and also in MZ and DZ twins. Overall, the differences in height and BMI between first- and second-born twins were modest even in early childhood, while adjustment for birth weight reduced the birth order differences but did not remove them for BMI.

Purpose: This study contributes to the growing literature on the association between sleep and obesity by examining the associations between hours of sleep, consistency of bedtime, and obesity among children in the US. Design: Analysis of a nationally representative sample of non-institutionalized children from the 2016-17 National Survey of Children’s Health. Setting: US, national. Subjects: Children ages 10-17 years (n = 34,640) Measures: Parent reported weeknight average hours of sleep and consistency of bedtime. Body mass index classified as underweight, normal, overweight or obesity using parent-reported child height and weight information, classified using CDC BMI-for-Age Growth Charts. Analysis: Multivariate logistic regression models were used to estimate associations between measures of sleep and body mass index weight category adjusting for individual, household and neighborhood characteristics. Results: An additional hour of sleep was associated with 10.8% lower odds of obesity, net of consistency in bedtime. After controlling for sleep duration, children who usually went to bed at the same time on weeknights had lower odds of obesity (24.8%) relative to children who always went to bed at the same time. Conclusion: Sleep duration is predictive of lower odds of obesity in US children and adolescents. Some variability in weeknight bedtime is associated with lower odds of obesity, though there were no additional benefits to extensive variability in bedtime.

Abstract Background The International Diabetes Federation (IDF) estimated that 1.1 million children and adolescents aged 14–19 years are living with diabetes. Diabetes is a chronic, progressive disease characterized by elevated levels of blood glucose. It is also recognized as a complex disease that affects people of different ages due to different causes. The present study aims to estimate the prevalence of pre-diabetes/diabetes at the national level. Additionally, the respective study determines the factors associated with pre-diabetes/diabetes conditions among adolescents at the national level. Methods The data for this study was carried out from the Comprehensive National Nutrition Survey (CNNS), the first-ever nationally representative nutrition survey of children and adolescents in India. The study used a sample size of 17,865 adolescent boys and 17,965 adolescent girls for the analysis. Descriptive statistics, bivariate analysis, and logistic regression analysis were done to carve out the results. Results The prevalence of pre-diabetes/diabetes was 12.3% and 8.4% among adolescent boys and girls in India, respectively. Body mass index and Subscapular skinfold thickness were the two most important predictors of pre-diabetes/diabetes among adolescents. Further, physical activities show a negative association with pre-diabetes/diabetes. Moreover, interaction models in the present study clearly reveal the fact that adolescent girls were less likely to suffer from pre-diabetes/diabetes than adolescent boys. Additionally, it was found that the prevalence of pre-diabetes/diabetes was high among adolescent girls from lower socio-economic strata. Conclusion The high prevalence of pre-diabetes and diabetes among adolescents portrayed serious public health concern in India. As body mass index and Subscapular skinfold thickness were positively associated with pre-diabetes/diabetes conditions among adolescents. Therefore, effective approaches are needed to be taken to tackle these pre-diabetes/diabetes conditions among adolescents and especially among adolescent boys.
