Parental Body Mass Index Is Associated With Adolescent Obesity in Taiwan.

Adolescent obesity is a crucial public health concern, and understanding its risk factors can facilitate the establishment of prevention policies. In this study we investigated the prevalence of adolescent obesity in Taiwan, determined the influential factors, and compared the prevalence of obesity in our study population with international indices. The cross-sectional study was an analysis of data from the 2010-2011 Nutrition and Health Survey in Taiwan, an anthropometric measurement and questionnaire survey of adolescents aged 11-18 years. Our sample was 1,826 adolescents (910 males and 916 females). Data were analyzed using logistic regression modeling. Based on body mass index standards specific to Taiwan norms, the prevalence of overweight and obesity in Taiwan adolescents was 12.4% and 16.8%, respectively. The prevalence was lower when international indices of overweight and obesity were applied. In logistic regression, obesity was linked to male gender, an obese father, overweight or obese mother, poor dietary attitudes, and perceived low dietary benefits. Monitoring and preventing adolescent obesity should focus on both adolescents and their parents. When planning behavioral change and education for adolescent obesity, health professionals and policy-makers should view the family as a unit. © 2016 Wiley Periodicals, Inc.
