OBJECTIVES
To examine social disparities and behavioral correlates of overweight and obesity over time among college students.
METHODS
Multilevel analyses of BMI, physical activity, and television viewing from 2 representative surveys of US college students (n=24,613).
RESULTS
Overweight and obesity increased over time and were higher among males, African Americans, and students of lower socioeconomic position and lower among Asians. Television viewing and in activity were associated with obesity, and disparities in these behaviors partially accounted for excess weight among African Americans.
CONCLUSIONS
Social disparities in overweight and obesity exist among college students. Promoting physical activity and reducing television viewing may counteract increasing trends.
目的
研究大学生中超重和肥胖现象随时间变化的社会差异及行为相关性。
方法
对来自美国大学生的2项代表性调查（n = 24,613）中的体重指数、身体活动及看电视情况进行多水平分析。
结果
超重和肥胖现象随时间增加，在男性、非裔美国人、社会经济地位较低的学生中更为普遍，而在亚洲学生中比例较低。看电视及缺乏活动与肥胖相关，这些行为差异部分解释了非裔美国人超重现象较多的原因。
结论
大学生中超重和肥胖存在社会差异。促进身体活动及减少看电视时间可能会抵消超重和肥胖现象增加的趋势。
