Abstract

Purpose: This study was conducted to investigate risk factors of obesity and its associated health problems in adolescence in Taiwan.

Methods: We enrolled 559 adolescent volunteers with equal numbers of females and males in 2008. Participants were divided into two groups: obese (body mass index [BMI] ≧95th percentile) and normal-weight adolescents (BMI: 15th ∼ 85th percentile). Each of them completed a questionnaire about lifestyle and parents' stature.

Results: 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 watching associated higher frequency of having sweetened soft drinks (P=0.012). In boys, this associated with higher frequency of eating snick (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).

Conclusion: 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.

Keywords: Adolescent; Blood pressure; Obesity; Physical activity; Waist circumference: Risk factor.
