Association between social frailty and quality of life in older patients with chronic heart failure: sequential multiple mediating effects of family insufficiency and social networks

TL;DR

This study finds that social frailty in older heart failure patients lowers their quality of life, and family support and social networks can help reduce this impact.

Contribution

The study identifies family insufficiency and social networks as key mediators between social frailty and quality of life in older heart failure patients.

Findings

Age, hospitalizations, and NYHA classification affect quality of life in older heart failure patients.

Family insufficiency and social networks mediate the relationship between social frailty and quality of life.

Reducing family insufficiency and expanding social networks can mitigate the negative effects of social frailty.

Abstract

Older patients with chronic heart failure have severe somatic symptoms, which lead to high levels of social frailty and loss of quality of life. Understanding the demographic and disease factors of quality of life and its relationship with social frailty is beneficial to overall health for older patients with chronic heart failure. This study aims to explore the relationship between social frailty and quality of life in older patients with chronic heart failure and to verify whether family insufficiency and social networks moderate this relationship.

A multi-centre cross-sectional study was conducted on 443 older patients with chronic heart failure from three tertiary hospitals in China. The study questionnaire included a general information questionnaire, the HALFT scale (social frailty), the Family APGAR Index (family insufficiency), the LSNS-6 (social networks), and the MLHFQ (quality of life). Hierarchical regression analysis was used to assess the factors influencing quality of life; the SPSS PROCESS Marco Plug-in was employed to conduct mediation analysis.

The results showed that age, the number of hospitalizations, and NYHA classification influenced the quality of life in older patients with chronic heart failure. Social frailty, family insufficiency, and social networks were related, and family insufficiency and social networks mediated the relationship between social frailty and quality of life, with mediating effect sizes of 25.87, 99.5 and 58.97%, respectively.

This study shows that high levels of social frailty are associated with reduced quality of life in older patients with chronic heart failure. Decreasing family insufficiency and extending social networks help alleviate social frailty’s adverse effects on the quality of life in older patients with chronic heart failure.
