Association between solid cooking fuels and functional disability: evidence from a cross-sectional and longitudinal study.

ABSTRACT:

Background

The combustion of solid cooking fuels is a major source of indoor air pollution, yet the association of solid cooking fuels with functional disability remains inadequately studied.

Methods

We analyzed data from five waves (2011-2020) of the China Health and Retirement Longitudinal Study (CHARLS), assessing functional disability through activities of daily living (ADL) and instrumental activities of daily living (IADL). Linear mixed-effects models (LMM) and time-varying Cox proportional hazards models were employed to examine the associations between cooking fuel type, fuel transitions, and the duration of solid fuel use on functional disability.

Results

Cross-sectional analyses revealed that individuals using solid cooking fuels faced a significantly higher
