Prevalence of social frailty and risk factors among community-dwelling older adults: A systematic review and meta-analysis.

BACKGROUND

Older people are more vulnerable to social frailty due to age, physical condition and socio-economic status. Since social frailty can lead to adverse health outcomes, it is essential to understand the current state of social frailty among community-dwelling older adults.

AIMS

To consolidate existing evidence for rates of social frailty and risk factors.

METHODS

Two researchers independently selected studies, extracted data, assessed the quality of the studies included in the literature, and calculated the rate of social frailty through a random-effects model with OR and 95 % CI for risk factors.

RESULTS

The literature search yielded a total of 81,414 articles, with 28 articles ultimately meeting the study criteria and being included in the meta-analysis. The prevalence of social frailty among community-dwelling older adults was 20.0 % (95 % CI 15.0 %-25.0 %, I = 99.5 %, P < 0.001). MSFI and other criteria yielded social frailty rates of 20.6 % and 18.3 %, respectively. The rate of social frailty was 20.2 % for the cross-sectional design and 19.3 % for the cohort design. The prevalence of social frailty is 20.2 % in Asian countries and 17.4 % in European countries. The rate of social frailty is 22.0 % for those aged 75 and over and 17.9 % for those under 75. Multiple chronic conditions, a major illness, marital status, sleep quality, and depressive symptoms are associated with social frailty.

CONCLUSION

Social frailty affects nearly one in five community-dwelling older adults, and having multiple chronic conditions, having a major illness, being single, poor sleep quality, and depression are all risk factors for social frailty.
