Risk factors of adolescent obesity in Taiwan and its association with physical activity, blood pressure and waist circumference

ABSTRACT

This study was conducted to investigate risk factors of obesity and its associated health problems in adolescence in Taiwan. We enrolled 559 adolescent volunteers with equal members of female and males in 2008. Participants were divided into two groups obese [body mass index [BMI] >/= 95[th] percentile] and normal-weight adolescents [BMI 15[th] [tilde] 85[th] percentile]. Each of them completed a questionnaire about lifestyle and parents' stature. Obese mother had high likelihood of having obese girls and boys [P=0.001]. Obese girls spent more time in watching TV [P=0.03] and had higher frequency of having sweetened soft drinks [P=0.016] than normal-weight group. Girls spent more time in TV drinks [P=0.018] and larger waist circumference [P=0.011]. Boys who had more frequent effective exercise had lower frequency of eating outside [P=0.01] and more services of vegetables [P=0.002]. There was no relation between hypertension and adolescent physical activity. Regardless of gender, obese group had higher waist circumference and blood pressure than normal-weight group [P<0.001]. There was a strong association between obese mother and adolescent obesity. More physical activity in adolescents associated with healthier dietary behaviors. Obese adolescents have higher waist circumference and blood pressure
