We sought to develop an index that incorporated various dietary and lifestyle behaviours that are associated with overweight/obesity status in adolescents. We assigned discrete scores into each component of the proposed index. The Diet-Lifestyle Index ranged from 11 to 57. We examined the accuracy of the index in relation to adolescents' body mass status using a sample of 2,008 students. The mean score of the index was 30.9+/-5.2 for boys and 31.4+/-4.7 for girls. The index was inversely associated with the odds of being obese/overweight (odds ratio = 0.93, 95% confidence interval=0.90-0.96), after adjusting for age and gender. Particularly, an 11/57-unit increase of the index was associated with a 6% and 9% decrease in the odds of being overweight/obesity in boys and girls, respectively (P<0.001). Thus, the proposed Diet-Lifestyle Index could be a useful tool in a primary healthcare setting for preventing obesity in adolescence.
我们试图开发一个指数，纳入与青少年超重/肥胖状况相关的各种饮食和生活方式行为。我们为提出的指数的每个组成部分分配了离散分数。饮食-生活方式指数的范围为 11 至 57。我们使用 2008 名学生的样本检查了该指数与青少年体重状况相关的准确性。男孩的指数平均得分为 30.9+/-5.2，女孩的指数平均得分为 31.4+/-4.7。该指数与肥胖/超重的几率呈负相关（比值比=0.93，95%置信区间=0.90-0.96），调整年龄和性别后。特别是，指数增加 11/57 个单位与男孩和女孩超重/肥胖几率分别降低 6%和 9%相关（P<0.001）。因此，拟议的饮食-生活方式指数可以成为初级保健环境中预防青少年肥胖的有用工具。
