Our study aimed to explore the associations between solid fuels burning for either heating or cooking and all-cause mortality based on 2859 participants from the China Health and Retirement Longitudinal Study during 2011-2018.
Logistic regression models were performed to estimate the risk for all-cause mortality between different types of fuels in the current longitudinal study. Furthermore, the combined impacts of applying solid fuels for both cooking and heating and the effect among those who switched types of fuels in cooking or heating during follow-up were also analyzed. Interaction and stratification analysis by covariables was applied further to explore the relationship between fuel burning and all-cause mortality.
After full-adjustment, usage of solid fuels was associated with higher all-cause mortality (for heating: OR = 1.93, 95% CI = 1.25, 3.00; for cooking: OR = 1.76, 95% CI = 1.10, 2.82). Using solid fuels for both cooking and heating (OR = 2.36; 95% CI, 1.38, 4.03) was associated with a higher risk of all-cause mortality, while using solid fuels with a single purpose was not (OR = 1.52; 95% CI, 0.90, 2.55). Protective tendencies were detected in switching solid to clean fuel for cooking (OR = 0.62; 95% CI, 0.32, 1.17) and heating (OR = 0.62; 95% CI, 0.35, 1.10).
Either cooking or heating with solid fuels increases the risk of all-cause mortality among Chinese mid-aged and aging people in the urban area of China.
本研究旨在基于 2011 年至 2018 年期间来自中国健康与退休纵向研究的 2859 名参与者，探讨固体燃料用于取暖或烹饪与全因死亡率之间的关系。
在当前的纵向研究中，使用 logistic 回归模型估计不同类型燃料与全因死亡率之间的风险。此外，还分析了同时使用固体燃料烹饪和取暖以及在随访期间转换烹饪或取暖燃料类型的综合影响。进一步应用协变量的交互和分层分析来探讨燃料燃烧与全因死亡率之间的关系。
在充分调整后，使用固体燃料与全因死亡率较高相关（用于取暖：OR=1.93，95%CI=1.25，3.00；用于烹饪：OR=1.76，95%CI=1.10，2.82）。同时使用固体燃料烹饪和取暖（OR=2.36；95%CI，1.38，4.03）与全因死亡率升高相关，而单一用途使用固体燃料则没有（OR=1.52；95%CI，0.90，2.55）。从烹饪（OR=0.62；95%CI，0.32，1.17）和取暖（OR=0.62；95%CI，0.35，1.10）转换为清洁燃料显示出保护趋势。
在中国城市地区，中年和老年人无论是烹饪还是取暖使用固体燃料都会增加全因死亡率的风险。
