Sources of income are associated with all-cause mortality risk in older people: results from the Chinese longitudinal healthy longevity survey (CLHLS).

ABSTRACT:

Background

Previous cross-sectional studies have shown that the main sources of income are associated with health issues, social behaviors, and quality of life. However, the outcomes did not focus on hard endpoints, such as mortality. We aimed to investigate the association between the main sources of income and all-cause mortality in older people using longitudinal data from the Chinese Longitudinal Healthy Longevity Survey.

Methods

In total, 18,218 older people were included and divided into five groups according to their main sources of income (i.e., family support, social welfare, pensions, work income, and other income). The association between the main sources of income and mortality was estimated by Cox proportional-hazards regression analysis.
