Methods: This is a cross-sectional study with 848 girls aged 12–18 years. A questionnaire about the sociodemographic cont...
Objectives: We evaluated, for the first time in Portugal, the prevalence of overweight and obesity according to parental education in a population of preschool-aged Portuguese children in 2009/2010 and 2016/2017. Methods: Anthropometric data were collected in public and private preschools (n = 1996 in 2009/2010; n = 2077 in 2016/2017). Body mass index was calculated and weight status categories were based on th...

This study compares the prevalence of overweight and obesity between WHO/IOTF criteria. A total of 17,277 Portuguese children aged 3-10 years old were analysed. The prevalences of overweight-obesity were higher at WHO classification (19.8%-20.7%) than at IOTF classification (8.2%-16.1%), (p<0.001). Agreement between the criteria were substantial for overweight (Kappa= 0.67, p<0.001) and moderate for obesity (Ka...
