Objective To evaluate the effectiveness of psychological health intervention in the elderly urban residents living on minimum subsistence allowances, and to search for a suitable psychological health intervention strategy. Methods The 112 elderly persons living on minimum subsistence allowances in Xuzhou were selected by stratified cluster sampling, and they were matched with 112 controls. The elderly persons living on minimum subsistence allowances were divided into intervention group and control group. A general intervention based on community involved psychological health and care lecture, psychodrama treatment and psychological consultancy was made on the intervention. The SCL-90 was used to evaluate the psychological health status and effectiveness of psychological health intervention.

Objective To explore the interaction of smoking and diabetes on stroke.Methods In this case-control study,a face to face questionnaire survey was conducted.Logistic regression models were used to analyze the relationship between smoking or diabetes and stroke.The indicators of interaction were calculated according to the Bootstrap method in this study.Results A total of 918 cases and 918 healthy controls,who participated in the chronic disease risk factor survey in Xuzhou in 2013,were included in this study.Logistic regression analysis found that cigarette smoking was associated with stroke (OR=1.63,95％ CI:1.33-2.00),and diabetes was also associated with stroke (OR=2.75,95％CI:2.03-3.73) after adjusting confounders.Compared with those without diabetes and smoking habit,the odds ratio of stroke in those with diabetes and smoking habits was 8.94 (95％CI:3.77-21.19).Diabetes and smoking combined interaction index was 3.65 (95％CI:1.68-7.94),the relative excess risk was 5.77 (95％ CI:0.49-11.04),the attributable proportion was 0.65 (95％ CI:0.42-0.87).Conclusion The results suggest that there are additive interactions between smoking and diabetes on stroke.
