云南省地方性不明原因猝死危险因素的病例对照研究

摘要

Objective To explore the potential risk factors to Ymman endemic sudden cardiac death (YESCD) and provide evidence for prevention. Methods Twenty-two cases and 24 controls were randomly selected from YESCD areas and non-YESCD areas, respectively. Both cases and controls were interviewed with unified questionnaires. Univatiate X2 test and multivariate conditional logistic stepwise regression was conducted with SPSS 13.0. The optimal regression model was established and evaluated. Results The univariate X2 teat revealed that presence or absence of 5 potential factors might possibly be associated to YESCD: appropriate places for storing dining utensils, pens for livestock, consumption of mushrooms, exposure to any pesticides, and sudden climate changes before onset(X2=12.206,4.779,5.741,6.120,10.754, P<0.05). Multivariate conditional logistic stepwise regression demonstrated that consumption of mushrooms was a protective factor(OR=0.115, P<0.05) and sudden climate change was a risk factor(OR=36.592, P<0.01). Conclusions Sudden climate change might be a risk factor contributing to YESCD, and eating mushrooms before the prevalence seasons may provide some protection.%目的 探讨可能引起云南省地方性不明原因猝死的危险因素,为制订确实有效的预防措施提供依据.方法 在猝死病区选择病例22人,在非病区选择对照24人,对病例和对照采用统一的调查表进行现场询问,应用SPSS 13.0统计软件进行单因素X2检验及多冈素lobistic回归筛选可疑危险因素,建立并评价最优回归模型.结果 经单因素X2检验,发现餐具存放位置、家中有无牲畜圈、发病前是否食用蕈子、发病前是否接触农药杀虫剂、发病前是否气候骤变5个可疑因素具有统计学意义(X2值分别为12.206、4.779、5.741、6.120、10.754,P<0.05);经多因素logistic回归筛选出食用蕈子为保护性因素[比值比(OR)=0.115,P<0.05)],气候骤变为危险因素(OR=36.592,P<0.01).结论 气候骤变可能是云南省地方性不明原因猝死的发病诱因,在猝死高发季节到来前食用蕈子可以起到一定的预防作用.
