To examine the longitudinal association between changes in health behaviors and depression and determine the mediating effect of health characteristics on this association.
Based on the first and second waves of the Survey of Health, Aging and Retirement in Europe (SHARE)-Israel, depressive symptoms of 1,524 Israelis aged 50 or older were analyzed using logistic regression.
Changes in physical activity and body weight are associated with depressive symptoms after adjusting for confounders. However, after adding measures of health, the respective correlations of weight gain and commenced physical activity with depression disappear, and the correlation between continued activity and depression is reduced.
Changes in health behaviors are related to mental health in late life, but their effect is mediated by physical and functional health. Future interventions should nevertheless target older individuals who stop physical activity and those who remain inactive to lessen the risk of depression.
探讨健康行为变化与抑郁之间的纵向关联,并确定健康特征在此关联中的中介作用。
基于欧洲健康、老龄化和退休调查(SHARE)-以色列的第一和第二波数据,使用逻辑回归分析了 1524 名 50 岁或以上以色列人的抑郁症状。
调整混杂因素后,身体活动和体重的变化与抑郁症状相关。然而,在加入健康测量后,体重增加和开始身体活动与抑郁的相关性消失,而持续活动与抑郁的相关性降低。
健康行为的变化与晚年的心理健康有关,但它们的影响是通过身体和功能健康来介导的。未来的干预措施仍应针对停止身体活动和不活跃的老年人,以降低抑郁风险。
