Cooking with biomass fuels has been reported to have adverse effects on health. This study aims to explore the association between cooking with biomass fuels and vision impairment among Chinese older adults aged 65 years and above. This cohort study drew on data from the 2011/2012 wave and the 2014 follow-up wave of the Chinese Longitudinal Healthy Longevity Survey. Participants' visual function was examined through a vision screening test. Exposure to indoor biomass fuels was self-reported. Cox proportional hazards models were applied to explore the relationship between biomass fuel use and vision impairment. Additionally, we compared the risk of vision impairment between participants who switched cooking fuel types and those who did not. Subgroup and interaction analyses were conducted to explore the potential effect modifiers. A total of 4711 participants were included in this study. During the follow-up, 1053 (22.35%) participants developed vision impairment. Cooking with biomass fuels increased the risk of vision impairment by 40% (hazard ratio [HR]: 1.40, 95% confidence interval [CI]: 1.21-1.61). Participants who switched from clean fuels to biomass fuels had a greater risk of vision impairment than persistent clean fuel users (HR: 1.44, 95% CI: 1.03-2.00). Greater effect estimates were found in participants who lived in eastern and central China and urban residents. Cooking with biomass fuels resulted in a greater risk of vision impairment among Chinese older adults. This risk also existed in those who changed their cooking fuels from clean fuels to biomass fuels. Further studies with an objective assessment of biomass fuel combustion are required to confirm our findings.
燃烧生物质燃料做饭被报道会对健康产生不良影响。本研究旨在探讨中国 65 岁及以上老年人中使用生物质燃料做饭与视力障碍之间的关系。这项队列研究的数据来自中国健康长寿追踪调查的 2011/2012 年波次和 2014 年随访波次。通过视力筛查测试来检查参与者的视觉功能。室内生物质燃料的暴露情况由自我报告。应用 Cox 比例风险模型来探讨生物质燃料使用与视力障碍之间的关系。此外，我们比较了转换和未转换烹饪燃料类型的参与者之间视力障碍的风险。进行了亚组和交互分析，以探讨潜在的效应修饰剂。共有 4711 名参与者纳入本研究。在随访期间，1053 名（22.35%）参与者出现了视力障碍。使用生物质燃料做饭会使视力障碍的风险增加 40%（风险比[HR]：1.40，95%置信区间[CI]：1.21-1.61）。从清洁燃料转换为生物质燃料的参与者比持续使用清洁燃料的参与者视力障碍的风险更高（HR：1.44，95% CI：1.03-2.00）。在中国东部和中部以及城市居民中，发现了更大的效应估计值。在中国老年人中，燃烧生物质燃料做饭会导致更高的视力障碍风险。这种风险也存在于那些将烹饪燃料从清洁燃料转换为生物质燃料的人身上。需要进一步的研究来客观评估生物质燃料的燃烧情况，以证实我们的发现。
