To identify factors associated with overweight/obesity among adolescents in Ho Chi Minh City, Vietnam.
In 2004, a cross-sectional survey was conducted using multi-stage cluster sampling. Weight and height of 2 678 students from 31 junior high schools in Ho Chi Minh City were measured. Dietary intake and physical activity were assessed using a validated food frequency questionnaire and a physical activity questionnaire. Parental, household and neighbourhood characteristics were also collected. Factors associated with overweight/obesity in adolescents were modelled using hierarchical, multivariate logistic regression. "Survey commands" in STATA were used to account for the multi-stage cluster sampling design.
After adjusting for other study factors, the odds of overweight/obesity was significantly higher for male gender (OR=3.1, 95% CI: 1.8, 3.8), younger age (OR=3.4, 95% CI: 2.1, 5.3), schools located in wealthy districts (OR=2.5, 95% CI: 1.8, 3.4), higher family economic status (OR=1.9, 95% CI: 1.1, 4.9), higher parental education (OR=2.0, 95% CI: 1.4, 2.9), overweight or obese parents (OR=3.5, 95% CI: 1.7, 7.0), more time spent watching TV (OR=4.3, 95% CI: 1.3, 14.7), frequent consumption of soft drinks (OR=3.0, 95% CI: 1.6, 5.3) and more time studying after class (OR=2.9, 95% CI: 1.7, 4.9). The odds of overweight/obesity was lower with the availability of fruit at home (OR=0.5, 95% CI: 0.3, 0.7), frequent consumption of fruit/vegetables (OR=0.3, 95% CI: 0.2, 0.4) and being physically active (OR=0.5, 95% CI: 0.4, 0.8).
Family/parental factors as well as children's lifestyle should be taken into account when planning interventions to prevent adolescent obesity.
确定越南胡志明市青少年超重/肥胖的相关因素。
2004年，采用多阶段整群抽样进行横断面调查。测量了胡志明市31所初中的2678名学生的体重和身高。使用经过验证的食物频率问卷和身体活动问卷评估饮食摄入和身体活动情况。还收集了父母、家庭和邻里的特征。采用分层多变量逻辑回归对青少年超重/肥胖的相关因素进行建模。使用STATA中的“调查命令”来考虑多阶段整群抽样设计。
在对其他研究因素进行调整后，男性超重/肥胖的几率显著更高（比值比[OR]=3.1，95%置信区间[CI]：1.8，3.8）、年龄较小（OR=3.4，95%CI：2.1，5.3）、位于富裕地区的学校（OR=2.5，95%CI：1.8，3.4）、家庭经济状况较高（OR=1.9，95%CI：1.1，4.9）、父母教育程度较高（OR=2.0，95%CI：1.4，2.9）、父母超重或肥胖（OR=3.5，95%CI：1.7，7.0）、看电视时间更长（OR=4.3，95%CI：1.3，14.7）、经常饮用软饮料（OR=3.0，95%CI：1.6，5.3）以及课后学习时间更长（OR=2.9，95%CI：1.7，4.9）。家中有水果（OR=0.5，95%CI：0.3，0.7）、经常食用水果/蔬菜（OR=0.3，95%CI：0.2，0.4）以及进行体育活动（OR=0.5，95%CI：0.4，0.8）会降低超重/肥胖的几率。
在制定预防青少年肥胖的干预措施时，应考虑家庭/父母因素以及儿童的生活方式。
