摘要
目的分析中国成年双生子人群的冠心病遗传度。方法利用中国双生子登记系统在11省、市募集的20477对≥25岁同性别双生子,构建结构方程模型计算遗传度。结果调整年龄、性别后,冠心病的遗传度为0.75(0.68~0.81)。亚组分析显示≥40岁组和女性人群中,冠心病患病主要受遗传因素的影响;而25~39岁组和男性的患病主要受环境因素的影响。结论冠心病患病受遗传和环境因素的影响,且遗传度较高。
Objective To analyze the heritability of coronary heart disease(CHD)among the Chinese twin adults.Methods A total of 20477 same-sex twin pairs aged 25 years and older from the Chinese National Twin Registry were interviewed.Structure equation model was used to estimate the heritability of CHD.Results After adjusting for age and gender,the overall heritability of CHD was 0.75(0.68-0.81).Stratified analyses showed that genetic factors play a more important role in CHD incidence in≥40 years or female twins.While the development of CHD was mainly influenced by environmental factors in 25-39 years or male twins.Conclusion CHD is influenced by both genetic and environmental factors and the heritability is high.
