Relationship between community cerebral stroke and cerebrovascular hemodynamics and body mass index

目的探讨脑卒中和脑血管血流动力学与体重指数的关系。方法随机抽取广东省恩平市东门、青云、西门、东安4个社区900例≥40岁体重正常、超重、肥胖的居民,分为正常体重组(520例),超重组(320例),肥胖组(60例)。调查其体重指数及腰围、臀围、血压等测量,并测量脑血管血流动力学,探讨脑卒中相关危险因素的情况。结果高血压、糖尿病发病率随体重指数上升而增加(P<0.05);脑血管血流动力、脑血管功能总分则随体重指数上升而降低(P<0.05)。结论肥胖和超重可致脑血流动力学异常,增加卒中风险。

Objective To investigate the relationship between community cerebral stroke and cerebrovascular hemodynamics and body mass index. Methods 900 residents over the age of 40 years with normal weight, overweight and obesity in Dongmen, Qingmen, Ximen and Dong''an communities of Enping City, Guangdong were randomly selected and divided into the normal weight group (520 residents), the overweight group (320 residents) and the obesity group (60 residents). The residents'' body mass index, waist circumference, hip circumference and blood pressure were investigated and their cerebrovascular hemodynamics was measured. The risk factors of cerebral stroke were explored. Results The incidences of hypertension and diabetes rose as the body mass index increased (P < 0.05);The cerebrovascular hemodynamics and total score of cerebrovascular function dropped as the body mass index increased(P < 0.05). Conclusion Obesity and overweight can cause cerebrovascular hemodynamic abnormalities and increase the risk of cerebral stroke.
