北京市老年人体重指数与代谢指标及心脑血管疾病的关系

Relation of BMI and metabolic indexes with cardio-cerebral vascular disease in Beijing elderly residents

目的分析北京市城乡老年人体重指数(BMI)与各代谢指标及心脑血管疾病的关系。方法2000年起对一个流行病学队列研究人群1827例老年人进行身高、体重、血压测量和多项血液代谢指标的检查,同时进行人口学因素及心脑血管疾病的调查。结果女性BMI、超重及肥胖显著高于男性;随着年龄增长,BMI、超重及肥胖的比例显著下降;患代谢综合征的女性高于男性。随着BMI的增加,收缩压、舒张压、空腹血糖、TG逐渐增高,而平均年龄逐渐降低;代谢综合征及其各组分中的高血压、空腹血糖异常、糖尿病、高TG血症增加,高TC血症及高LDL-C血症也显著增加;冠心病患病率增高。结论随着BMI的增加,老年人多种代谢异常明显增高。

Objective To investigate the association between body mass index（BMI） and metabolic indexes and cardio-cerebral vascular disease in the elderly community residents in Beijing. Methods In a cohort study,physical examination was performed in 1 827 Beijing elderly residents in 2000. Demographic data, information of health status were also collected. Results BMI was significantly higher in women than in men, and decreased with ageing. Overweight and obesity in women were higher than those in men. The prevalence rates of overweight and obesity decreased with ageing too. The prevalence rate of the metabolic syndrome diagnosed by CDS definition was high in women. Mean systolic blood pressure, diastolic blood pressure, FPG, TG increased and age decreased with increasing BMI; at the same time, metabolic syndrome, hypertension, abnormal fasting blood glucose, diabetes mellitus, hypertriglyceridemia and hypercholesterolemia increased. The prevalence rate of coronary heart disease increased with BMI also. Conclusion Metabolic disorder and cardio-vascular disease increased with increasing BMI among elderly residents.
