The relationships between environmental correlates of adolescent obesity are complex and not yet well defined by current research, especially when considering age and gender.
The purpose of this study was to test a model of proximal (home) and distal (neighbourhood) environmental correlates of obesity for adolescent age and gender groups.
This was a descriptive, cross-sectional study, using the 2007 National Survey of Children's Health of 39 542 children ages 11-17 years.
The model fit the data well for early adolescents (ages 11-14 years) (root mean square standard error of approximation [RMSEA] 0.040, 90% confidence interval [CI]: 0.039-0.041; comparative fit index [CFI] 0.947; Tucker-Lewis index [TLI] 0.929) and middle adolescents (ages 15-17 years) (RMSEA 0.037, 90% CI: 0.036-0.038; CFI 0.052; TLI 0.937). The model also fit the data well for boy adolescents (RMSEA 0.038, 90% CI: 0.037-0.039; CFI 0.951; TLI 0.935) and girl adolescents (RMSEA 0.038, 90% CI: 0.037-0.040; CFI 0.949; TLI 0.932).
All models provide loadings of the environmental correlates of adolescent obesity for specific age and gender groups that can be used for early identification of risks and targeted interventions.
青少年肥胖与环境因素之间的关系复杂，目前的研究尚未明确界定，尤其是在考虑年龄和性别因素时。
本研究旨在检验一个关于青少年年龄和性别组肥胖的近端（家庭）和远端（社区）环境相关因素的模型。
这是一项描述性横断面研究，使用了2007年对39542名11至17岁儿童进行的全国儿童健康调查。
该模型对青少年早期（11至14岁）的数据拟合良好（近似均方根误差[RMSEA]为0.040，90%置信区间[CI]：0.039 - 0.041；比较拟合指数[CFI]为0.947；塔克 - 刘易斯指数[TLI]为0.929），对青少年中期（15至17岁）的数据拟合也良好（RMSEA为0.037，90% CI：0.036 - 0.038；CFI为0.052；TLI为0.937）。该模型对青少年男性（RMSEA为0.038，90% CI：0.037 - 0.039；CFI为0.951；TLI为0.935）和青少年女性（RMSEA为0.038，90% CI：0.037 - 0.040；CFI为0.949；TLI为0.932）的数据拟合同样良好。
所有模型都提供了特定年龄和性别组青少年肥胖与环境相关因素的负荷情况，可用于早期风险识别和针对性干预。
