The impact of social isolation on the health status and health-related quality of life of older people

To investigate for socially isolated older people, and older people at risk of social isolation: (1) health status and health-related quality of life (HRQL); (2) the relationship between social isolation and health status/HRQL; (3) the relationship between two alternative measures of health status/HRQL.

Health status and health state values were much lower than UK general population age-matched norms. After controlling for depression, physical co-morbidities, age, gender, living alone status, employment and accommodation, social isolation was significantly associated, to a degree that was clinically relevant, with EQ-5D DSI, SF-6D (SF-12) and SF-12 MCS scores. The potential for ceiling effects on the EQ-5D with this population was identified.

This work highlights the burden that social isolation may have on the health and well-being of older people. The potential HRQL gains from addressing social isolation may be considerable, with those at risk of social isolation also a key target group.
