The objective of this study was to investigate whether life satisfaction and depressive symptoms are independent predictors of mortality in a non-Western sample of adults. The sample included 5,131 adults (ages 50-95 at baseline) in Taiwan who participated in the Survey of Health and Living Status of the Near Elderly and Elderly. There were 1,815 deaths recorded over a 10-year period. Higher life satisfaction significantly predicted lower risk of mortality after controlling for age, sex, education, marital status, and health status. Depressive symptoms significantly predicted higher risk of mortality. A significant interaction with age revealed that the protective effect of life satisfaction weakened with age. The results suggest that life satisfaction and depressive symptoms independently predict mortality risk in adults.
本研究的目的是调查在一个非西方成年人样本中,生活满意度和抑郁症状是否是死亡率的独立预测因素。样本包括台湾5131名成年人(基线年龄为50 - 95岁),他们参与了老年及高龄老人健康与生活状况调查。在10年期间记录到1815例死亡。在控制了年龄、性别、教育程度、婚姻状况和健康状况后,较高的生活满意度显著预测了较低的死亡风险。抑郁症状显著预测了较高的死亡风险。与年龄的显著交互作用表明,生活满意度的保护作用随年龄增长而减弱。结果表明,生活满意度和抑郁症状独立预测成年人的死亡风险。
