ABSTRACT=Abstract
Objectives
This study aimed to examine the association of solid fuel use for cooking and heating with the progression of multimorbidity.
Methods 
A total of 5,437 participants from the China Health and Retirement Longitudinal Study were included. Multivariate logistic regression models were used to estimate the odds ratios (ORs) and 95% confidence intervals (CIs) for the associations of the independent and joint effects of solid fuel use for cooking and heating with the progression of multimorbidity. 
Results 
The proportion of participants reporting both solid fuel use for cooking and heating was 59.0% at baseline. Both solid fuel use for cooking and heating was associated with the progression of multimorbidity (adjusted OR: 1.42, 95% CI: 1.19 – 1.70), compared with both clean fuel use. 
Conclusion
Solid fuel use for cooking and heating play an important role in the progression of multimorbidity. Therefore, solid fuel reduction should be considered in developing multimorbidity control and prevention programmes.
