ABSTRACT To determine whether the U.S. Centers for Disease Control and Prevention (CDC; CDC Reference) or International Obesity Task Force (IOTF; IOTF Reference) BMI cut-off points for classifying adiposity status in children are more effective at predicting future health risk.
The sample (N=1709) included 4- to 15-year-old (at baseline) boys and girls from the Bogalusa Heart Study. Overweight and obesity status were determined using both the CDC Reference and IOTF Reference BMI cut-off points at baseline. The ability of childhood overweight and obesity, determined from the two BMI classification systems, to predict obesity and metabolic disorders in young adulthood (after a 13- to 24-year follow-up) was then compared.
Independently of the classification system employed to determine adiposity based on childhood BMI, the odds of being obese and having all of the metabolic disorders in young adulthood were significantly (p<0.05) higher in the overweight and obese groups by comparison with the nonoverweight groups. Childhood overweight and obesity, determined by both the CDC Reference and IOTF Reference, had a low sensitivity and a high specificity for predicting obesity and metabolic disorders in young adulthood. Overweight and obesity as determined by the CDC Reference were slightly more sensitive and slightly less specific than the corresponding values based on the IOTF Reference.
Overweight and obesity during childhood, as determined by both the CDC and IOTF BMI cut-off points, are strong predictors of obesity and coronary heart disease risk factors in young adulthood. The differences in the predictive capacity of the CDC Reference and IOTF Reference are, however, minimal.

    ABSTRACT: Abstract Aim: The aim of the present study was to investigate the association between the duration of predominant breastfeeding and the waist to height ratio—a validated index of abdominal adiposity. Methods: Waist to height ratio (waist circumference/height, both in centimetres) and body mass index (weight (kg)/height (m2) ) were collected from 896 children aged 5.00–7.99 years. Mothers of these children reported on early feeding behaviour and indicated their highest level of education attained. The 75th and 95th percentiles were used to define high and very high waist to height ratio. Overweight and obesity defined by body mass index were also included in the analyses. Results: There were a higher proportion of children �75th percentile for waist to height ratio among the never breastfed group compared to breastfed children. This was statistically significant only in females (P = 0.002). Females predominantly breastfed for 4–6 months (P = 0.003) and >12 months (P = 0.006) had significantly lower mean waist to height ratio than those never breastfed. A similar pattern emerged with body mass index. Among males, delaying solids for �6 months was associated with significant decreases in waist to height ratio and body mass index. Females were six times more likely to have waist to height ratio �95th percentile than children predominantly breastfed for 4–6 months. This was statistically significant. Increasing maternal education was related to breastfeeding duration. Conclusion: Prevalence of overweight and high abdominal adiposity was significantly greater among females who were never breastfed. Females who were predominantly breastfed for at least 4–6 months had the lowest mean waist to height ratio and body mass index and also the greatest reduction in the risk of very high waist to height ratios.

    ABSTRACT: By using path analysis, the aim of this study iso show how anxiety, low self-esteem and a decrease in hours of sleep interact to lead to an increase in overweight in children. A random sample of 291 schoolchildren was included. A cross-sectional design was used, measuring their body mass index (BMI) and applying the Stait-Trait Anxiety inventory for Children and the Children' Depression Inventory. The mean sleep time was 9hours and 50minutes. There was an inverse relationship between hours of sleep and BMI. Similarly, anxiety and low self-esteem were predictors of the number of hours of sleep. These data allow it to be concluded that, on one hand, the population studied sleeps less than the 10 or 11hours recommended for their age. On the other hand, it has been demonstrated how certain emotional states can encourage increased BMI in children, but this relationship is associated with reduced sleep.
