Abstract

Abstract: Objective To explore the association between household solid fuel use and motoric cognitive risk syndrome (MCR) among the elderly population in China. Methods Based on a cross-sectional design, a total of 1 040 couples aged 60 years and above enrolled in the China Health and Retirement Longitudinal Study (CHARLS) were analyzed. Household solid fuels included coal, crop residue, and wood burning for heating and/or cooking. After excluding cognitive impairment and mobility disabilities, the individuals presenting with both slow gait and subjective cognitive decline were considered to have MCR. Logistic regression model was applied to assess the association between household solid fuel use and MCR prevalence in both spouses and individual MCR. Results Among 2 080 participants (1 040 couples), a total of 264 (12.69%) participants had MCR. The proportions of both spouses without MCR, husband-only MCR, wife-only MCR and both spouses with MCR were 78.37%, 8.46%, 9.42% and 3.75%, respectively. Compared with clean fuel, the use of solid fuel for cooking could increase the risk of MCR in rural households (OR=1.41, 95%CI: 1.01-1.96). MCR was also associated with the use of solid fuel for both heating and cooking in rural households (OR=1.92, 95%CI: 1.12－3.27), whereas no significant association was found in urban households (P>0.05). Within the household, wives who used solid fuel for cooking had a higher risk of MCR (OR=1.56, 95%CI: 1.03－2.35) than those who used clean fuel. MCR was also significantly associated with solid fuel use for both heating and cooking (OR=1.93, 95%CI: 1.08－3.45) among wives, while no above significant association was observed among husbands (P>0.05). Conclusions In Chinese households, solid fuel use is associated with the risk of MCI among wives.
