OBJECTIVE A number of individual risk factors for childhood obesity have been identified, but only some of these are amenable to prevention. To assess the amount of cases in a general population attributable to these risk factors, adjusted population-attributable fractions were estimated. DESIGN Cross-sectional study. SETTING Obligatory school entry examination in 2001/2002 in six Bavarian ...

The aim of this study was to determine the prevalence of child and adolescent obesity in Spain in 2012. METHODS We performed a cross-sectional probability sample of 1018 children, representative of the Spanish pop...

OBJECTIVE To establish the prevalence of overweight and obesity in Mexican children 10 to 17 years of age according to the percentiles from both the Centers of Disease Control and Prevention (CDC) and the International Obesity Task Force (IOTF).

Childhood overweight and obesity (ow/ob) has become a serious threat to many countries, including China. However, limited evidence was obtained from longitudinal data in China. This study examined the secular trends and geographic variation in the prevalence of ow/ob and obesity only, and age, gender, and urban-rural disparities among school-aged children across China. Data from children aged 6...

BACKGROUND In some previous studies, prenatal exposure to persistent organochlorines such as 1,1,-dichloro-2,2-bis(p-chlorophenyl)ethylene (p,p´-DDE), polychlorinated biphenyls (PCBs), and hexachlorobenzene (HCB) has been associated with higher body mass index (BMI) in children. OBJECTIVE Our goal was to evaluate the association of maternal serum levels of β-hexachlorocyclohexane (β-HCH), p,p...
