To examine the differences in the prevalence of overweight and obesity based on the cutoff references established by the International Obesity Task Force (IOTF) and the Working Group on Obesity in China (WGOC), the prevalence of underweight on the IOTF reference, and the sociodemographic correlates of body weight statuses in Taiwanese adolescents.
Overweight and obesity in 10,371 Taiwanese adolescents were determined by the IOTF and WGOC cutoff references for body mass index (BMI). Underweight was determined by the IOTF. The prevalence of overweight and obesity using the IOTF standard were compared to those using the WGOC standard. Associations of body weight statuses with gender, age, residential status, and parental education level were also examined.
Using the IOTF standard, 3.4% were underweight, 15.2% were overweight, and 6.1% obese, whereas 14.1% were considered overweight and 8.7% were obese by the WGOC standard. For both genders, more adolescents were classified as overweight by the IOTF standard and as obese by the WGOC standard. Although females were more likely to be underweight than males, males were more likely to be overweight or obese than females. For both genders, although older age increased the risk of being underweight, younger age increased the risk of being overweight or obese. For males, living in urban areas was associated with being overweight, and low paternal education level was associated with being obese.
The prevalence of overweight and obesity may differ depending on the reference standard consulted. Paternal education level and urbanicity were associated with gender differences in the proportion of adolescents who were overweight or obese.
根据国际肥胖工作组（IOTF）和中国肥胖工作组（WGOC）制定的切点参考标准、IOTF 参考标准下的消瘦率以及台湾青少年体重状况的社会人口学相关性，研究超重和肥胖的流行率存在差异。
采用 IOTF 和 WGOC 体重指数（BMI）切点参考标准来确定 10371 名台湾青少年的超重和肥胖情况。采用 IOTF 标准来确定消瘦情况。将使用 IOTF 标准确定的超重和肥胖流行率与使用 WGOC 标准确定的流行率进行比较。还检查了体重状况与性别、年龄、居住状况和父母教育水平的关联。
使用 IOTF 标准，3.4%为消瘦，15.2%为超重，6.1%为肥胖，而 WGOC 标准则有 14.1%被认为超重，8.7%为肥胖。对于男女两性，更多的青少年被 IOTF 标准归类为超重，被 WGOC 标准归类为肥胖。尽管女性比男性更容易消瘦，但男性比女性更容易超重或肥胖。对于两性，尽管年龄较大增加了消瘦的风险，但年龄较小增加了超重或肥胖的风险。对于男性，居住在城市地区与超重有关，父亲的教育水平较低与肥胖有关。
超重和肥胖的流行率可能因参考标准而异。父教育水平和城市化与超重或肥胖青少年的性别比例差异有关。
