Abstract:Objective To explore the correlation of smoking and family history of stroke with stroke morbidity, and to analyze their interaction effect on stroke. Methods The data of this study were collected from the National Screening and Intervention Program for Stroke High Risk Population. Permanent residents aged ≥40 years in communities were selected to serve as the subjects of a questionnaire survey, body measurement and laboratory tests. A total of 16,584 subjects were enrolled into the final analysis. SPSS19.0 software was used to perform χ2 test, single-factor and multivariate logistic regression analyses. Additive models were used to analyze the interaction effect of smoking and family history on stroke. Therelative excess risk due to interaction (RERI), attributable proportion (AP) of interaction and the synergy index (SI) were calculated. Results Among the subjects, there were 208 (1.25%) stroke patients, 1,050 (6.33%) subjects with family history of stroke, 1,467 (8.85%) smokers, and 205 (1.23%) subjects with smoking and family history. The results of interaction effect analyses based on additive models revealed that after adjusting for factors such as sex, age, hypertension, dyslipidemia, diabetes, obesity, lack of exercise, atrial fibrillation and valvular heart disease, and previous transient ischemic attack, there was an increased risk of stroke in non-smokers with family history (OR=3.390, 95%CI:2.272-5.057), smokers without family history (OR=2.345, 95%CI:1.464-3.759), smokers with family history (OR=5.938, 95%CI:3.318-10.624) compared with non-smokers without family history. RERI, SI and AP were 1.202 (0.582-2.808), 1.322(1.335-1.412) and 20.243(17.541-26.431) respectively. Conclusion There are additive interactions between smoking and family history on stroke. The risk of stroke is higher in subjects simultaneously having smoking and family history than in ones having either smoking or family history.
