However, few longitudinal studies have explored the long-term impacts of indoor air pollution from household solid fuel use on child growth. We aimed to investigate the association between household air pollution (HAP) from solid fuel use and childhood stunting in Chinese children.<\/jats:p><\/jats:sec><jats:sec><jats:title>Method<\/jats:title><jats:p>The longitudinal data from the Chinese Family Panel Study over 2010\u20132018 were included in this study with a total of 6,013 children aged 0\u201315 years enrolled at baseline. Exposure to HAP was measured as solid fuel use for cooking, while solid fuel was defined as coal and firewood\/straw according to the questionnaire survey. Stunting was defined as\u22122SD below the height-for-age z-score (HAZ) of the reference children. Logistic regression and Cox proportional hazards models with time-varying exposures were employed to estimate the association between childhood stunting and HAP exposure.<\/jats:p><\/jats:sec><jats:sec><jats:title>Results<\/jats:title><jats:p>At baseline, children with exposure to HAP from combusting solid fuels had a relatively higher risk of stunting [OR (95%CI): 1.42 (1.24\u20131.63)]. Among children without stunning at baseline, those living in households with solid fuel use had a higher stunting risk over an 8-year follow-up [HR (95%CI): 2.05 (1.64\u20132.57)]. The risk of childhood stunting was increased for those with HAP exposure from firewood\/straw combustion or with longer exposure duration [HR (95%CI): 2.21 (1.74\u20132.79) and 3.01 (2.23\u20134.08), respectively]. Meanwhile, this risk was significantly decreased among children from households switching from solid fuels to clean fuels [HR (95%CI): 0.53 (0.39\u20130.70)]. Solid fuel use was suggested to be a mediator of the relationship between poor socioeconomic factors (i.e., household income and parental education level) and childhood stunning, with a mediation effect ranging from 11.25 to 14.26%.<\/jats:p><\/jats:sec><jats:sec><jats:title>Conclusions<\/jats:title><jats:p>HAP exposure from solid fuel use was associated with childhood stunting. Poor parental education and low household income might be socioeconomic factors contributing to solid fuel use. Therefore, household energy policies to facilitate access to clean fuels are urgently needed, especially for low-income and low-educated households.<\/jats:p><\/jats:sec>","DOI":"10.3389\/fpubh.2022.985786","type":"journal-article","created":{"date-parts":[[2022,10,17]],"date-time":"2022-10-17T05:37:50Z","timestamp":1665985070000},"update-policy":"https:\/\/doi.org\/10.3389\/crossmark-policy","source":"Crossref","is-referenced-by-count":15,"title":["Household
