Association between indoor ventilation frequency and frailty among Chinese older adults.

ABSTRACT:

Background

Frailty is a common geriatric syndrome that imposes a heavy disease burden globally. Indoor ventilation is a crucial measure for improving air quality. However, the association between indoor ventilation frequency (IVF) and frailty remains unclear. This study aimed to explore this association among Chinese older adults.

Methods

We used data from 5,511 older adults in the Chinese Longitudinal Healthy Longevity Survey (CLHLS) 2018 and an external validation sample of 718 older adults from Chongqing. Logistic regression models and linear regression models were employed to assess the association between IVF and frailty and its seasonal variations. We further conducted subgroup analysis to examine differences across various populations. All statistical analyses were pe
