老年人群体质指数和腰围与心血管病危险因素聚集的研究

目的探讨老年人群体质指数、腰围与心血管病危险因素聚集的关系。方法对654名老年人进行健康查体,对不同体质指数（BMI）、腰围（WC）老年人的收缩压（SBP）、舒张压（DBP）、总胆固醇（TC）、甘油三酯（TG）、高密度脂蛋白胆固醇（HDL-C）和空腹血糖（FPG）平均水平及高血压、高TC、高TG、低HDL-C、糖尿病检出率进行分析,对心血管病危险因素聚集性进行分析。结果BMI、WC升高是老年人最常见的心血管病危险因素。随着BMI、WC的增加,老年人SBP、DBP、TC、TG、FPG平均水平明显升高,HDL-C平均水平降低,高血压、高TC、高TG、糖尿病的检出率明显增高。BMI为24．0～27．9ks／m^2时,老年人高血压、高TC、高TG、糖尿病的检出率分别为59．74％、3．89％、28．57％、10．06％,患高血压、高TG、糖尿病的危险性分别是正常BMI的1．65、1．88、1．85倍;BMI≥28．0ks／m^2时,老年人高血压、高TC、高TG、糖尿病的检出率分别为83．05％、5．08％、35．59％、15．25％,患高血压、高TG、糖尿病的危险性分别是正常BMI的5．44、2．60、2．98倍。男性WC≥85cm、女性WC≥80cm时,老年人高血压、高TC、高TG、糖尿病的检出率分别为66．15％、4．47％、29．57％、10．12％,患高血压、高TC、高TG的危险性分别是正常WC的3．52、6．51、1．68倍。BMI≥24．0kg／m^2或男性WC≥85cm、女性WC≥80cm的老年人伴随多个心血管病危险因素的比例显著增高。结论BMI、WC升高是导致老年人群心血管病危险因素聚集的重要因素。

Study on the body mass index and waist circumference of aged with clustering of other cardiovascular risk factors

OBJECTIVE: To explore the relation of body mass index (BMI) and waist circumference (WC) of the aged with clustering of other cardiovascular risk factors. METHODS: Total 654 old people were checked up, and the systolic blood press (SBP), diastolic blood press (DBP), total cholesterol (TC), triglyceride (TG), high-density lipoprotein cholesterol (HDL-C) and fasting plasma glucose (FPG) of them were investigated according to different BMI and WC, then the other cardiovascular risk factors analysis was carried out on the detection rates of SBP, DBP, TC, HDL-C, FPG level and high blood pressure, high TC, high TG. The clustering of the other cardiovascular risk factors was analyzed. RESULTS: The rising of BMI and WC was regular cardiovascular risk factor in the aged. The average level of SBP, DBP, TC, TG, and FPG of the aged was obviously rising along with BMI and WC increasing, meanwhile the HDL-C was obviously decreased, and the detection rates of high blood pressure, high TC, TG and diabetes mellitus were obviously increased. When the BMI was 24 kg/m(2)-27.9 kg/m2, the detection rates of high blood pressure, high TC, TG and diabetes mellitus were 59.74%, 3.89%, 28.57%, 10.06% respectively, and their risks of suffering high blood pressure, high TC and TG were 1.65, 1.88, 1.85 times of those with normal BMI. When the BMI > or = 28.0 kg/m2, the detection rates of high blood pressure, high TC, TG and diabetes mellitus were 83.05%, 5.08%, 35.59%, 15.25% respectively, and their risks of suffering high blood pressure, high TC and TG were 5.44, 2.60, 2.98 times of those with normal BMI. When the man WC > or = 85 cm or women WC > or = 80 cm, the detection rates of high blood pressure, high TC, TG and diabetes mellitus were 66.15.%, 4.47%, 29.57%, 10.12%, and their risks of suffering high blood pressure, high TC and TG were 3.52, 6.51, 1.68 times of those with normal BMI. The rate of the aged with several cardiovascular risk factors was significantly increased for those with BMI > or = 24.0 kg/m2 or man WC > or = 85 cm or women WC > or = 80 cm. CONCLUSION: The rising of BMI and WC should be important factor for the clustering of cardiovascular risk factors in the aged.
