暴露于空气污染会带来各种疾病的发病效应，但关于空气污染与衰老之间关系的研究却很少。本研究旨在通过一项具有全国代表性的研究，确定中国老年人群中用于烹饪和加热的家庭空气污染与肌肉和肌肉减少症之间的关系。这项横断面研究包括2011年至2015年中国健康与退休纵向研究中60岁及以上的人群。肌肉减少症的诊断定义为低肌肉质量伴低肌肉力量和/或体能下降。采用广义相加分析和三种模型的剂量依赖性分析来评估不同烹饪和加热模式对肌肉和肌肉减少症的影响。共纳入8126名中国老年人，男性占多数（53.7%），平均年龄为67.3 ± 6.0岁。与使用清洁燃料烹饪相比，使用固体燃料烹饪显示肌肉力量（β =-0.424，95%CI：-0.767，-0.082，P = 0.01，模型3）和质量（β =-0.034，95%CI：-0.051，-0.017，P < 0.01，模型3）分别显著下降。与用于加热的清洁燃料相比，用于加热的固体燃料与较低的肌肉强度相关（β = −0.637，95%CI：−1.033，−0.241，模型3中P < 0.01）。与使用清洁燃料做饭和取暖相比，使用固体燃料做饭和取暖与肌肉强度（β = −0.835，95% CI：−1.306，−0.365，P < 0.01，模型3）和质量（β = −0.038，95% CI：−0.061，−0.015，P < 0.01，模型3）降低有关。烹饪用固体燃料与低肌肉力量的风险显著增加有关（模型3中调整的OR = 1.29，95%CI：1.11，1.50，P < 0.01）和质量（模型3中调整的OR = 1.35，95% CI：1.11，1.61，P < 0.01），可能的肌肉减少症（模型3中调整的OR = 1.33，95% CI：1.19，1.48，P < 0.01）和肌肉减少症（模型3中调整的OR = 1.44，95% CI：1.21，1.72，P < 0.01）。取暖用固体燃料与肌肉力量低下（模型3中调整后的OR = 1.30，95%CI：1.09，1.56，P < 0.01）和可能的肌肉减少症（模型3中调整后的OR = 1.49，95%CI：1.31，1.70，P < 0.01）显着相关。在具有低肌肉力量的固体燃料数量与可能的肌肉减少症之间的关联中显示出剂量依赖性方式。清洁燃料烹饪和固体燃料加热与可能的肌肉减少症的患病率正相关，而清洁燃料烹饪和加热与可能的肌肉减少症的患病率正相关（模型3中调整的OR = 1.34，95% CI：1.14，1.57，P < 0.01）。我们的研究结果表明，固体燃料的烹饪和固体燃料的使用数量可能会促进肌肉损失和肌肉减少症的发生和发展。
Exposure to air pollution brings the advent effect for various diseases, but study about the relationship between air pollution and ageing is scant. We aimed to determine the associations between household air pollution for cooking and heating with muscle and sarcopenia in Chinese older population by a nationally representative study. This cross‐sectional study included individuals aged 60 and above from the China Health and Retirement Longitudinal Study between 2011 and 2015. The diagnosis of sarcopenia was defined by low muscle mass with low muscle strength and/or reduced physical performance. Generalized additive analyses and dose‐dependent analyses with three models were used to assess the effects of different pattern of cooking and heating on muscle and sarcopenia. A total of 8126 Chinese older individuals with predominant male (53.7%) and mean age of 67.3 ± 6.0 years were included in our study. Solid fuel use in cooking showed significant declines in muscle strength (β = −0.424, 95% CI: −0.767, −0.082, P = 0.01 in model 3) and mass (β = −0.034, 95% CI: −0.051, −0.017, P < 0.01 in model 3), when compared with clean fuel use in cooking, respectively. Solid fuel for heating was correlated with lower muscle strength (β = −0.637, 95% CI: −1.033, −0.241, P < 0.01 in model 3) than clean fuel for heating. The joint use of solid fuel for cooking and heating was associated with reduced muscle strength (β = −0.835, 95% CI: −1.306, −0.365, P < 0.01 in model 3) and mass (β = −0.038, 95% CI: −0.061, −0.015, P < 0.01 in model 3) than clean fuel for cooking and heating. Solid fuel for cooking was associated with significantly increased risk of low muscle strength (adjusted OR = 1.29, 95% CI: 1.11, 1.50, P < 0.01 in model 3) and mass (adjusted OR = 1.35, 95% CI: 1.11, 1.61, P < 0.01 in model 3), possible sarcopenia (adjusted OR = 1.33, 95% CI: 1.19, 1.48, P < 0.01 in model 3) and sarcopenia (adjusted OR = 1.44, 95% CI: 1.21, 1.72, P < 0.01 in model 3) compared with clean fuel for cooking. Solid fuel for heating had a significant correlation with low muscle strength (adjusted OR = 1.30, 95% CI: 1.09, 1.56, P < 0.01 in model 3) and possible sarcopenia (adjusted OR = 1.49, 95% CI: 1.31, 1.70, P < 0.01 in model 3). Dose‐dependent manner was shown in the associations between the number of solid fuel with low muscle strength and possible sarcopenia. Clean fuel for cooking and solid fuel for heating was positively associated with the prevalence of possible sarcopenia than clean fuel for cooking and heating (adjusted OR = 1.34, 95% CI: 1.14, 1.57, P < 0.01 in model 3). Our findings suggested that solid fuel for cooking and the number of solid fuel use potentially facilitates the onset and progression of muscle loss and sarcopenia.
