大学生体力活动、心肺耐力与抑郁风险关系的纵向研究

Longitudinal study of physical activity,cardiorespiratory fitness and risk of depression among college students

目的:探讨大学生体力活动、心肺耐力、抑郁风险三者之间的关系。方法:采用国际体力活动问卷(IPAQ)、体质健康测试和抑郁筛选量表(CES-D量表)对1 067名在校大学生(其中男生518人,女生549人)体力活动、体质健康水平和抑郁水平进行了评估,研究采用纵向研究设计,追踪测量持续两年时间,每隔1年测量一次,采用潜变量增长模型和Logistic回归对所测得的数据进行分析。结果发现,经过年龄、BMI、独生子女、父母文化程度、自评家庭经济、肺活量等可能的混杂因素校正后,体力活动水平每下降10 MET-min/d可以引起男生抑郁事件的发生风险率增加1.1%(OR=1.011),女生抑郁事件发生风险率增加2.1%(OR=1.021);耐力跑成绩每增加10秒的可以引起男生抑郁事件的发生风险率增加1.5%(OR=1.015),女生抑郁事件发生风险率增加6.3%(OR=1.063)。结论:大学生体力活动水平、心肺耐力与抑郁风险之间的关系密切,提高体力活动水平、心肺耐力水平能有效地降低抑郁风险。

Objective： To determine the relations between physical activity,cardiorespiratory fitness and depressive symptoms among college students. Methods： The sample included 518 males and 549 females. International Physical Activity Questionnaire（ IPAQ）,fitness test and Center for Epidemiologic Studies Depression Scale（ CES- D） were used to measure physical activity,cardiorespiratory fitness and depression respectively for 3 times in 2 years longitude study. Latent Growth Modeling and Logistic regression were used to assess the data. Results： After adjustment for age,BMI,time between visits,parents＇ education level,family financial condition and lung capacity,each 10MET- min / d decline in physical activity level,increased the odds of depression risk by approximately 1.1% in men and 2. 1% in women. Each 10 seconds increase in cardiorespiratory fitness test（ 1000 m run for men and 800 m run for women）,increased the odds of depression risk by approximately1. 5% in men and 6. 3% in women. Conclusion： There was a close relation between physical activity,cardiorespiratory fitness and depressive symptoms among college students. To improve physical activity and cardiorespiratory fitness can decrease depression risk of college students.
