Exposure to second-hand smoke (SHS) is linked to ischemic heart disease (IHD), but research on burden in China and across socio-demographic index (SDI) regions is limited. Based on the Global Burden of Disease 2021, we used joinpoint regression and age-period-cohort model to analyze the trend in deaths and disability-adjusted life years (DALYs) of IHD attributable to SHS in China and five SDI regions from 1990 to 2021. Results showed that the age-standardized rates of death and DALY in China remained at a high level, and declined more slowly compared to the five SDI regions. The increasing trends in IHD death and DALY rates were found among Chinese men aged 25-94 and women aged 80-94, while the rates decreased in the five SDI regions. The period and cohort effects indicated a larger decline in deaths and DALYs among Chinese women than men, with the largest reduction in high SDI region. The population attributable fraction for IHD deaths and DALYs due to SHS in China decreased from 8.82% and 9.71% in 1990 to 7.45% and 8.09% in 2021, but remained the highest level compared to the five SDI regions. The findings highlight the need to reduce SHS exposure, especially among men and the elderly in China.
接触二手烟（SHS）与缺血性心脏病（IHD）有关，但在中国以及不同社会人口指数（SDI）地区关于其负担的研究有限。基于《2021年全球疾病负担》，我们采用连接点回归和年龄-时期-队列模型分析了1990年至2021年中国及五个SDI地区因二手烟导致的缺血性心脏病死亡和伤残调整生命年（DALYs）的趋势。结果显示，中国的年龄标准化死亡率和伤残调整生命年率仍处于较高水平，与五个SDI地区相比下降更为缓慢。在中国25至94岁男性和80至94岁女性中发现缺血性心脏病死亡率和伤残调整生命年率呈上升趋势，而在五个SDI地区则呈下降趋势。时期和队列效应表明，中国女性的死亡和伤残调整生命年下降幅度大于男性，在高SDI地区下降幅度最大。中国因二手烟导致的缺血性心脏病死亡和伤残调整生命年的人群归因分数从1990年的8.82%和9.71%降至2021年的7.45%和8.09%，但与五个SDI地区相比仍处于最高水平。研究结果凸显了减少二手烟暴露的必要性，尤其是在中国的男性和老年人中。
