Abstract

Background and objectives: Physical capability, social support, loneliness, depression, and anxiety predict life satisfaction in older adults. Currently, no systematic review and meta-analysis have been conducted to investigate the strength of these associations globally. Therefore, this study quantified the strength of these associations.

Research design and methods: A systematic literature search was conducted using MEDLINE, EMBASE, APA PsycINFO, Web of Science, and Scopus. We included observational studies assessing the association between physical capability, social support, loneliness, depression, and anxiety with life satisfaction in adults aged 65+.

Results: In total, 10,552 articles were identified, of which 78 studies in 164,478 participants were included in the systematic review and 57 were included in the meta-analysis. Greater life satisfaction was significantly associated with greater physical capabilities (odds ratio [OR] = 2.64; 95% confidence interval [CI]: 2.01-3.45; p < .001, k = 35, n = 33,732), higher social support (OR = 3.27; 95% CI: 2.59-4.13, k = 20 studies, n = 13,228), reduced loneliness (OR = 3.30; 95% CI: 2.53-4.30, k = 11, n = 33,638), depression (OR = 4.76; 95% CI: 3.10-7.32, k = 24, n = 64,097), and anxiety (OR = 5.10; 95% CI: 2.21-11.78, k = 5, n = 43,368). The strength of associations did not vary between Western and Eastern countries, year of publication, or quality. Gender was a moderator: Loneliness was more strongly associated with life satisfaction in females. Age was also a moderator; the association between social support and life satisfaction weakened with increasing age.

Discussion and implications: Improving the physical capabilities of older individuals, fostering social support, and alleviating feelings of loneliness, depression, and anxiety may help build life satisfaction in older individuals, which policy-makers and healthcare professionals should prioritize when implementing strategies.
