Abstract:
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.
