BACKGROUND
Socioeconomic status (SES) has well known associations with a variety of health conditions and behaviors in adults but is unknown in adolescents.
METHODS
Multilevel analysis was conducted to examine the associations between individual and neighborhood-level measures of SES and physical activity and body mass index in a sample of 1554 6th grade girls selected at random from 36 middle schools across 6 geographic regions in the United States that participated in the Trial of Activity for Adolescent Girls (TAAG). Data on parental education and employment, and receipt of subsidized school lunch were collected by questionnaire. Neighborhood-level SES was measured by the Townsend Index. Nonschool physical activity levels were measured by accelerometer and type, location and context was measured using a 3 day physical activity recall (3DPAR).
RESULTS
After controlling for race, lower parental education and higher levels of social deprivation were associated with higher BMI. In a model with both variables, effects were attenuated and only race remained statistically significant. None of the indices of SES were related to accelerometer measured physical activity. Bivariate associations with self-reported Moderate-Vigorous Physical Activity (MVPA) location and type (3DPAR) varied by SES.
CONCLUSION
Among adolescent girls in the TAAG Study, the prevalence of overweight is high and inversely related to individual and neighborhood SES.
背景
社会经济地位（SES）与成年人的各种健康状况和行为有密切关联，但在青少年中尚不清楚。
方法
对美国 6 个地理区域的 36 所中学中随机抽取的 1554 名 6 年级女生进行了多水平分析，以检验个体和社区 SES 指标与身体活动和体重指数之间的关系。调查问卷收集了父母教育和就业以及获得补贴学校午餐的数据。使用 Townsend 指数衡量社区 SES。通过加速度计测量非学校体育活动水平，并使用 3 天体力活动回忆（3DPAR）测量活动类型、位置和情境。
结果
在控制种族因素后，父母教育程度较低和社会剥夺程度较高与 BMI 较高相关。在同时包含两个变量的模型中，效应减弱，只有种族因素仍具有统计学意义。SES 的任何指标均与加速度计测量的身体活动无关。与自我报告的中高强度体力活动（MVPA）位置和类型（3DPAR）的双变量关联因 SES 而异。
结论
在 TAAG 研究中的青春期女孩中，超重的患病率很高，与个体和社区 SES 呈负相关。
