There was a statistically significant difference in the incidence of eating disorders by genders, self-assessed learning pressure, physical activity and depressive symptoms(χ ² =63.65, 23.17, 34.24, 70.66, P<0.05). After adjusting for demographic variables, the results of multiple Logistic regression analysis showed that physical activity and depressive symptoms were positively correlated with eating disorders ( OR =0. 59 2. 58 P<0.01). In the depression group, lower level of physical activity, was associated with higher rate of eating disorders.

【摘要】 目的 了解大学生体力活动和抑郁症状与进食障碍的关联, 为开展大学生进食障碍干预工作提供理论依据。方 法采用整群抽样法, 抽取山东省济南市3所本科院校共计2 712名大学生开展问卷调査, 采用一般资料调査表、国际体 力活动问卷短卷、病人健康问卷抑郁量表和进食态度问卷进行调査。 结果 被调査大学生中, 体力活动未达标组1 750名 (64.5%), 达标组962名（35. 5%);有抑郁症状者488名（18. 0%);进食障碍者452名（16. 7%)。不同性别、自评学习压 力、体力活动及抑郁症状的大学生进食障碍检出率差异有统计学意义（χ ²值分别为63.65,23. 17,34.24,70. 66, P值均<0. 05)。调整人口学变量后, 多元Logistic回归分析结果显示, 体力活动和抑郁症状均与进食障碍呈正相关（ OR值分别为 1.59,2.58, P值均<0.01)。相同抑郁症状组别中, 体力活动水平越低, 进食障碍检出率越髙。 结论 大学生体力活动和抑 郁症状与进食障碍有关。可通过积极改善抑郁症状、增加体育锻炼等途径干预进食障碍。
