Creating a supportive environment for older adults in China ——exploring factors associated with the need for home modifications based on a cross-sectional survey in Central China

Abstract

BackgroundA supportive home environment is critical to the safety and quality of life of older adults. Home modification is an effective way to build a supportive home environment for older adults’ aging in place. However, there is a lack of knowledge on older adults’ need for home modifications in China.MethodsWe conducted a cross-sectional survey in three provinces of China (Hubei, Hunan, and Henan) using stratified and cluster sampling methods in 2021. A total of 5485 older adults aged 60 and over were included. The outcome variables were: need for home modifications, level of need, and type of modification needed. Exposure variables included: demographic and socioeconomic characteristics, as well as health conditions. Logistic and Poisson regressions were applied to examine the needs for home modifications and its associated factors.ResultsNearly 30% of the older adults needed home modifications. The most common choice of home modification was the need for handrails at the bedside, toilet, or threshold (31.64%), and paving un-slip tiles or vinyl flooring (17.45%). Age (IRR = 1.01, P < 0.001), education (IRR = 1.11, P < 0.01), and level of assistance (IRR = 2.31, P < 0.001) were more likely to be positively associated with needs for modification. Participants in the age group of 70 to 79 years, with primary school education, and low-level physically dependent had significantly higher needs for modifications than those of advanced age, lower level of education, or higher level of physically dependent (p < 0.01).ConclusionsThe overall need for home modifications in China is low. Home modification programs are needed to tailor individuals’ needs and provide services to those with the most home modification need.
