OBJECTIVES
We assessed income-specific trends in obesity rates among a diverse population of California adolescents.
METHODS
We used data from 17,535 adolescents who responded to the California Health Interview Survey between 2001 and 2007 to examine disparities in obesity prevalence by family income and gender.
RESULTS
Between 2001 and 2007, obesity prevalence significantly increased among lower-income adolescents but showed no statistically significant differences among higher-income adolescents after adjustment for age, gender, and race/ethnicity. Although the overall disparity in obesity by family income doubled in this time period, trends were more consistent among male adolescents than among female adolescents.
CONCLUSIONS
The magnitude of the income disparity in obesity prevalence among California adolescents more than doubled between 2001-2007. The overall leveling off of adolescent obesity prevalence rates could indicate that efforts to decrease childhood obesity are having an impact; however, our results suggest that efforts to prevent childhood obesity may be failing to help adolescents from lower-income families, particularly male adolescents.
目的
我们评估了加利福尼亚州青少年中不同人群的特定收入群体的肥胖率趋势。
方法
我们使用了 2001 年至 2007 年间对加利福尼亚健康访谈调查做出回应的 17535 名青少年的数据，以检查家庭收入和性别对肥胖症患病率的差异。
结果
在 2001 年至 2007 年间，低收入青少年的肥胖症患病率显著增加，但在调整年龄、性别和种族/民族后，高收入青少年的肥胖症患病率没有统计学意义上的差异。尽管这一时期家庭收入方面的肥胖总体差异增加了一倍，但男性青少年的趋势比女性青少年更为一致。
结论
在 2001-2007 年间，加利福尼亚州青少年中肥胖症患病率的收入差异幅度增加了一倍以上。青少年肥胖症患病率的总体稳定可能表明，减少儿童肥胖的努力正在产生影响；然而，我们的结果表明，预防儿童肥胖的努力可能未能帮助来自低收入家庭的青少年，尤其是男青少年。
