Predictors of Depression and Insomnia in Community-Dwelling Elderly People: A Cross-Sectional Evidence of Their Bidirectional Relationship

The Relationships Among Family Functioning, Sleep Quality and Quality of Life in Chinese Community-Dwelling Older Adults with Insomnia: A Structural Equation Model

OBJECTIVES

The proportion of individuals with insomnia is increasing, and many older adults have insomnia. This study aimed to explore the relationships between family functioning and quality of life (QOL) among community-dwelling older adults with insomnia, as well as to explore the mediating role of sleep quality in this relationship.

METHODS

The participants were 225 older adults with insomnia from community health service centers in Chongqing, China. The Family Care Index (APGAR) was used to assess family functioning, the Pittsburgh Sleep Quality Index (PSQI) was used to assess sleep quality, and the 36-item Short-Form Health Survey (SF-36) was used to assess QOL.

RESULTS

The results showed that family functioning would be positively associated with QOL (p = .005) and that this relationship would be partially mediated by higher sleep quality (p < .001).

CONCLUSIONS

Family functioning has a direct effect on QOL and an indirect effect on QOL through the regulation of sleep quality. Maintaining good family functioning is important for improving sleep quality and QOL in older adults with insomnia.

CLINICAL IMPLICATIONS

Developing family functioning-based assessments and targeted intervention strategies could be beneficial for older adults with insomnia.

The Effect of Depressive and Insomnia Symptoms in Quality of Life among Community-Dwelling Older Adults

The purpose of this study was to investigate the effects of depressive symptoms, insomnia symptoms, and comorbid depressive and insomnia symptoms on the quality of life among community-dwelling older adults in an urban area of central Greece. A cross-sectional study was conducted on 200 older adults (aged ≥ 60) collected from five Open Care Centers for Elderly People of the Municipality of Larissa, Greece. Data were obtained through a questionnaire that included demographic, socioeconomic, and health-related characteristics; the World Health Organization Quality of Life (WHOQoL)-Bref questionnaire; the Geriatric Depression Scale; and the Athens Insomnia Scale. The prevalences of depression, insomnia, and comorbid depression and insomnia were 28% (95% confidence interval (95% CI): 21.8-34.2%), 40.5% (95% CI: 33.7-47.3%), and 19% (95% CI: 13.5-24.5%), respectively. The mean WHOQoL-Bref score for all domains was approximately 14.50, with the highest mean value observed for psychological health (14.79 ± 2.60), followed by the physical health (14.49 ± 2.66), social relationships (14.39 ± 2.03), and environmental domains (14.32 ± 1.90). All WHOQoL-Bref domains were negatively correlated with depression and insomnia. Older adults with depressive symptoms, insomnia symptoms, and comorbid depressive and insomnia symptoms had lower scores in all quality of life dimensions compared with those without.
