The present work reports the changing prevalence of childhood overweight/obesity in Spanish boys and girls over the period 1993-2011, and examines the risk factors apparent in 2011. Children with a body mass index (BMI) of ≥ 25 were deemed overweight, and those with a BMI of ≥ 30 were deemed obese. Overweight and obesity was consistently more common among boys than among girls. The prevalence of overweight and obesity in Spain increased over the study period. CONCLUSIONS: According to the 2011 data, children who undertook no physical activity, or whose parents/guardians had a low level of education, showed the highest prevalence of obesity.enAttribution-NonCommercial-ShareAlike 4.0 Internationalhttp://creativecommons.org/licenses/by-nc-sa/4.0/AdolescentBody Mass IndexChildChild, PreschoolCross-Sectional StudiesEducational StatusExerciseFemaleHumansMaleOverweightPediatric ObesityPrevalenceRisk FactorsSex FactorsSpainresearch article29565154open access10.20960/nh.13551699-5198https://doi.org/10.20960/nh.1355
