【摘要】 目的 探讨家族遗传因素在Ⅱ型糖尿病发生发展中的作用。方法 采用遗传流行病学病例对照研究方法,对常州市350个家系(184个Ⅱ型糖尿病先证家系和166个对照家系)进行了Ⅱ型糖尿病的遗传流行病学研究。结果 病例组一级亲属总的患病率为3.47%,与对照组的1.03%相比,差异有非常显著性(χ2 =17.66,P<0.01);无论其父母、同胞或子女,均以病例亲属的患病率显著高于对照; Ⅱ型糖尿病家族中实际发病数超过其二项分布的理论概率范围,即Ⅱ型糖尿病的分布呈明显的家族聚集性; 单因素和多因素logistic回归模型拟合也提示,家族史仍是Ⅱ型糖尿病的最主要危险因素。结论 遗传因素在Ⅱ型糖尿病发病中占有重要地位。 【关键词】 Ⅱ型糖尿病 家族聚集性 流行病学

【Abstract】 Objective To study the relationship between genetic factors and the development of NIDDM. Methods A case-control study including 350 pedigrees (184 cases and 166 controls) was carried out to explore the etiology of family aggregation of NIDDM in Changzhou city,March 1997. Results The total prevalence rate of the first-degree relatives was 3.47%, significantly higher than 1.03% in controls (χ2=17.66,P<0.01). The similar results were also found in their parents, siblings and younger generation. Results Results from binominal distribution analysis showed that the number of cases in the families of NIDDM was significantly bigger than the theoretical range, indicating that there was significant familial aggregationin in the occurance of NIDDM. Simple and multiple logistic regression analysis also showed that genetic factor was one of the most important factors in the development of NIDDM. Conclusion Genetic factor was an important factor in the occurance of NIDDM. 【Key words】 Non-insulin-dependent diabetes mellitus Family aggregation Epidemiology
Ⅱ型糖尿病是一种慢性非传染性终生性疾病,随着生活水平的提高,它的患病率逐年升高[1],至今为止,Ⅱ型糖尿病的易患危险因素尚未完全明了[1,2]。近年来,研究者逐渐注意到Ⅱ型糖尿病的发生与家族因素有关,呈家族聚集现象[3]。为进一步探讨家族遗传因素在Ⅱ型糖尿病中的作用,我们于1997年12月至1998年3月设计了一种遗传流行病学的病例对照调查方法, 对常州市Ⅱ型糖尿病的家族聚集性进行了流行病学研究。
