Housing Conditions Change and its Association with Lung Function, Mobility Limitations, and Depressive Symptoms Among Middle-Aged and Older Chinese

As a modifiable social determinant of health, housing conditions present an opportunity to promote healthy aging. This study investigated the relationship between housing condition changes and health among Chinese. Participants from China Health and Retirement Longitudinal Study (aged 45+, N = 8,423) reported their housing conditions in 2011-2013 and their lung function, mobility limitations, and depressive symptoms were measured in 2013-2018. Regression models with interaction terms were used. Individuals living in homes with better physical environments (e.g., barrier-free facilities) and more utilities (e.g., water, electricity) reported lower risk of mobility limitations and depressive symptoms. Home improvement in utilities lowered the risk of mobility limitations, especially among individuals living in homes with no or few utilities. Many Chinese older adults resided in homes lacking aging-friendly amenities, which was associated with worse physical and mental health. Enhancing home utilities could modify the negative impact of poor housing on physical health.
