Carbon monoxide (CO) poisoning is a public health concern in developing countries especially in China with a high disease burden. We aimed to focus on non-occupational CO poisoning caused by household coal heating secular trends based on registry data in Jinan, China, and we aim to provide further evidence and suggestions for public health policy. We analyzed the occurrence and development trend and assess the spatial-temporal epidemiological characteristics of non-occupational CO poisoning caused by household coal heating in Jinan between 2007 and 2021. Among total of 6588 CO poisoning, 5616 cases (85.25%) and 180 deaths caused by household coal heating was identified during study period. The cumulative incidence rate was 5.78 per 100,000 person-years and the mortality rate was 0.19 per 100,000 person-years. The incidence in urban areas (6.55 per 100,000 person-years) was higher than rural areas (5.04 per 100,000 person-years), and there was a statistical difference between urban and rural (P < 0.001) (P < 0.001). The poisoning time point mainly occurs in the sleep stage. In Jinan, socioeconomic status, accessibility to health services and rural status are determinants for CO poisoning incidence and mortality. Implementation of urban and rural central heating renovation is an effective way to further reduce the disease burden of CO poisoning in the future.
一氧化碳（CO）中毒是发展中国家（尤其是中国）的一个公共卫生关注点，其疾病负担很高。我们旨在根据中国济南的登记数据，关注由家庭燃煤取暖引起的非职业性 CO 中毒的季节性趋势，为公共卫生政策提供进一步的证据和建议。我们分析了 2007 年至 2021 年济南地区由家庭燃煤取暖引起的非职业性 CO 中毒的发生和发展趋势，并评估了其时空流行病学特征。在总共 6588 例 CO 中毒中，有 5616 例（85.25%）和 180 例死亡归因于家庭燃煤取暖。累积发病率为 5.78/10 万人年，死亡率为 0.19/10 万人年。城区（6.55/10 万人年）的发病率高于农村地区（5.04/10 万人年），城乡之间存在统计学差异（P<0.001）（P<0.001）。中毒时间主要发生在睡眠阶段。在济南，社会经济地位、获得卫生服务的机会和农村状况是 CO 中毒发病率和死亡率的决定因素。实施城乡集中供暖改造是未来进一步降低 CO 中毒疾病负担的有效途径。
