阿勒泰地区中老年人体重与心血管病危险因素的关系

Study the level of body weight effect on blood pressure lipidemia and blood glucose in Altai area

目的 :分析阿勒泰地区中老年人群体重与心血管疾病危险因素的关系 ,探讨适宜的体质指数 (BMI)、腰围 (WC)、腰臀围比 (WHR)切点。方法 :测定体质指数、腰围、臀围、收缩压、舒张压、血总胆固醇、高密度脂蛋白、低密度脂蛋白、甘油三酯、空腹血糖、空腹胰岛素、餐后 2小时血糖 ,并计算胰岛素敏感指数。将体质指数、腰围以及腰臀围比分层处理 ,分析不同的体重对相关疾病危险因素的预测价值。 结果:从 BMI≥ 2 5、男性 WC≥ 85 cm、女性WC≥ 80 cm、男性 WHR≥ 0 .95、女性 WHR≥ 0 .85开始 ,收缩压、舒张压、甘油三酯、空腹血糖、空腹胰岛素、餐后 2小时血糖开始增加 ,高密度脂蛋白、胰岛素敏感指数开始减少 ,差别有统计学意义 (P <0 .0 5 )。 结论 :肥胖程度与心血管疾病危险因素有关 ,对血压、血脂。

objective: To study of relationships between the level of body weight and the risk factors of cardiovascular diseases in Aletai area in Xinjiang. To explore of optimal BMI, WC, WHR. Methods: We chosed 223 cases, aged 42 to 78 to determine the systolic pressure,diastolic pressure, total cholesterol, high density lipoprotein, low density lipoprotein, triglyceride,fasting blood glucose, fasting insulin and postprandial blood glucose. Devided the BMI into 8 groups, WC into 6 groups, WHR into 5 groups. To apply the analysis of variance and analyse the data. Results: In the BMI≥25 groups, the level of DBP, TG, FBG, 2hBG, FINS was significantly higher, HDL ch, ISI was significantly lower than BMI<25 groups(P<0.05); In the male WC≥85 cm groups, the level of TG, FBG, FINS was significantly higher, HDL ch, ISI was significantly lower than WC<85 cm groups; In the female WC≥80 cm groups, the level of TG, FBG, 2hBG, FINS was significantly higher, HDL ch, ISI was significantly lower than WC<80 cm groups(P<0.05); In the male WHR≥0.95 groups, the level of SBP, TG, FBG, 2hBG, FINS was significantly higher, ISI was significantly lower than WHR<0.95 groups; In the female WHR≥0.85 groups, the level of SBP, TG, 2hBG, FINS was significantly higher, HDL ch, ISI was significantly lower than WHR<0.85 groups(P<0.05). Conclusion: There are some characteristcs of obesity in middle old aged population in area of Aletai in Xinjiang. Study suggests that the optimal BMI is 25; the optimal WC on male is 85 cm, on female is 80 cm; the optimal WHR on male is 0.95, on female is 0.85.
