■抑郁症状代表了重大的公共卫生挑战,影响老年人的心理健康。尽管如此,对于日常生活活动(ADL)能力如何与中国老年人的生活满意度和抑郁症状相关的理解仍然有限.
■本研究旨在探讨中国老年人ADL与抑郁症状的关系,特别侧重于研究在这种背景下生活满意度的中介作用。
■该研究利用了2020年收集的中国健康与退休纵向研究(CHARLS)的数据。包括8,343名60岁及以上的个体。使用STATA17.0和SPSS26.0进行分析,采用描述性统计,卡方检验,皮尔逊相关性,并使用百分位Bootstrap方法进行5,000个样本的中介分析,探讨ADL之间的相互关系,生活满意度,和抑郁症状。
■ADL与生活满意度呈正相关(r=0.129,p<0.01),与抑郁症状呈负相关(r=-0.313,p<0.01)。此外,生活满意度与抑郁症状呈负相关(r=-0.360,p<0.01)。在中介效应的模型中,ADL直接,对中国老年人抑郁症状具有显著的预测作用(β=-0.193,t=-17.827,p<0.001)。将生活满意度纳入回归方程后,ADL对抑郁症状的直接预测作用仍然显著(β=-0.177,t=-17.099,p<0.001);ADL对生活满意度有显著正向预测作用(β=0.007,t=4.959,p<0.001),生活满意度对抑郁症状有显著负向预测作用(β=-2.235,t=-27.799,p<0.001)。此外,ADL对抑郁症状的直接效应(-0.177)及其中介效应(-0.016)分别占总效应的91.71%和8.29%(-0.193),分别。
■ADL与中国老年人抑郁症状的风险呈负相关,生活满意度在这段关系中起着重要的中介作用。旨在改善患有ADL障碍的老年人的生活满意度的干预措施可以有效地减少或预防抑郁症状的发作。
UNASSIGNED: Depressive symptoms represent a significant public health challenge, impacting the mental well-being of older adults. Despite this, the understanding of how activities of daily living (ADL) abilities correlate with life satisfaction and depressive symptoms among older Chinese adults remains limited.
UNASSIGNED: This study aims to investigate the relationship between ADL and depressive symptoms in older people Chinese individuals, with a specific focus on examining the mediating role of life satisfaction within this context.
UNASSIGNED: The study utilized data from the China Health and Retirement Longitudinal Study (CHARLS) collected in 2020. A cohort of 8,343 individuals aged 60 years and above was included. The analysis was conducted using STATA 17.0 and SPSS 26.0, employing descriptive statistics, chi-square tests, Pearson correlations, and mediation analysis using the percentile Bootstrap method with 5,000 resamples to explore the interrelations among ADL, life satisfaction, and depressive symptoms.
UNASSIGNED: ADL is positively correlated with life satisfaction (r = 0.129, p < 0.01) and negatively correlated with depressive symptoms (r = -0.313, p < 0.01). Additionally, life satisfaction and depressive symptoms are negatively correlated with each other (r = -0.360, p < 0.01). In the model of the mediating effect, ADL directly, significantly and negatively predicts depressive symptoms in the Chinese older people (β = -0.193, t = -17.827, p < 0.001). After incorporating life satisfaction into the regression equation, the direct predictive effect of ADL on depressive symptoms remains significant (β = -0.177, t = -17.099, p < 0.001); furthermore, ADL has a significant positive predictive effect on life satisfaction (β = 0.007, t = 4.959, p < 0.001) and life satisfaction significantly negatively predicts depressive symptoms (β = -2.235, t = -27.799, p < 0.001). Furthermore, the direct effect of ADL on depressive symptoms (-0.177) and its mediating effect (-0.016) account for 91.71% and 8.29% of the total effect (-0.193), respectively.
UNASSIGNED: ADL is inversely associated with the risk of depressive symptoms among older people Chinese individuals, with life satisfaction serving as a significant mediator in this relationship. Interventions aimed at improving life satisfaction in older people individuals with ADL impairments may effectively reduce or prevent the onset of depressive symptoms.
