云南省农村居民2011年与2021年哮喘患病情况及社会经济地位对其疾病经济负担影响比较

Prevalence and the impact of socioeconomic position on economic burden of asthma in rural adult residents of Yunnan province:a comparison between 2011 and 2021

目的比较云南省农村居民2011年与2021年哮喘患病情况及社会经济地位对其疾病经济负担的影响,为当地哮喘的预防控制工作提供参考依据。方法采用多阶段分层随机抽样方法于2011年1—11月和2021年1—11月在云南省分别抽取8300名和7700名≥35岁农村居民进行问卷调查,比较2011年与2021年该地区农村居民的哮喘患病情况及社会经济地位对其疾病经济负担的影响。结果云南省2011和2021年最终纳入分析的8187名和7572名农村居民中,哮喘患者分别为111例和122例,哮喘患病率分别为1.36%和1.61%,2011年与2021年哮喘患病率比较差异无统计学意义(P>0.05);2021年云南省农村哮喘患者的人均直接经济负担、人均间接经济负担和人均疾病经济负担分别为(4230.11±1767.06)元、(69.57±23.97)元和(4299.68±1385.83)元,分别高于2011年云南省农村哮喘患者人均直接经济负担、人均间接经济负担和人均疾病经济负担的(2776.85±1203.58)元、(49.86±15.36)元和(2826.71±1049.80)元(均P<0.05);2021年与2011年不同社会经济地位哮喘患者的疾病经济负担比较,2021年社会经济地位低、中等偏下、中等偏上和高的人均疾病经济负担均较2011年有所加重(均P<0.05),哮喘患者疾病经济负担的增加量由多至少依次为社会经济高、低、中等偏下和中等偏上。结论云南省2011年与2021年农村居民的哮喘患病率无明显变化,但2021年哮喘患者的疾病经济负担有所加重,且不同社会经济地位哮喘患者的疾病经济负担变化存在差异。

Objective To compare the prevalence of asthma and the impact of socioeconomic position(SEP)on economic burden of asthma among rural residents in Yunnan province in 2011 and 2021,and to provide evidence for the prevention and treatment of asthma in the population.Methods Using stratified multistage random sampling,we conducted face-to-face surveys during 2011 and 2021 among 8187 and 7572 rural residents aged≥35 years in Yunnan province.A self-designed questionnaire was used to collect information on demographics,SEP,asthma clinically diagnosed at township and upper level hospitals,and asthma-related economic burden for analyses on asthma prevalence and the influence of SEP on asthma-induced economic burden among the participants.Results Among the rural adults surveyed in 2011 and 2021,totally 111 and 122 asthma cases were identified,with the asthma prevalence rate of 1.36%and 1.61%and without significant difference between the two prevalence rates.Compared to those reported by the adults with asthma incidence in 2011,significantly higher per capita asthma-related direct cost(4230.11 vs.2776.85 Chinese Yuan),indirect cost(69.57 vs.49.86),and total cost(4299.68 vs.2826.71)were reported by the adults with asthma incidence in 2021(all P<0.05).Contrasting to that in 2011,the per capita asthma-related total cost increased significantly in 2021 for the asthma sufferers of various SEP groups(P<0.05 for all)and the total cost increment varied in a descending order for the asthma sufferers with high,low,lower-middle,and upper-middle SEP.Conclusion Among the rural adult residents in Yunnan province,the prevalence of asthma was not significantly different but the economic burden of asthma sufferers increased substantially between 2011 and 2022 and the sufferers'economic burden varied with their socioeconomic position.
