超声研究成年后颈动脉粥样硬化与胎儿期宫内发育的关系

Relation between intrauterine growth and carotid atherosclerosis in adult life by ultrasonography

目的 探讨成年颈动脉粥样硬化与胎儿期宫内生长情况之间的关系。方法 对2036例有完整出生记录的50岁以上成人进行颈动脉超声检查，测量颈总动脉及其分叉处内中膜厚度，判断有无动脉粥样硬化。抽取外周静脉血进行各项生化检查，并填写心脑血管调查表。分析颈动脉粥样硬化与出生时、成年后各项指标之间的关系。结果 颈动脉内中膜增厚组的出生体质量和头围均明显低于正常组，出生体质量〈2500g的胎儿成年后颈动脉硬化的发生率最高，调整心脑血管危险因素后仍比出生体质量3000-3500g者高。结论 胎儿期宫内发育不良是颈动脉粥样硬化的独立影响因素。

Objective To investigate the relation between intrauterine growth and the development of carotid atherosclerosis in later life. Methods The intima-media thickness of carotid was measured with ultrasonography in 2036 people aged above fifty who had complete birth records, and divided into normal and abnormal group. They were asked to fill in the cardio-cerebrovascular questionnaire, and venous blood samples were taken and analysed for various biochemical parameters. The relation between carotid atherosclerosis and various parameters at birth and in adult life was assessed. Results The birthweight and head circumference in abnormal group were less than those in normal. The prevalence of carotid atherosclerosis was greatest in those weighed 2500g or less, whose risk of carotid atherosclerosis was greater than those weighed between 3000g and 3500g, after adjustment for cardiovascular risk factors. Conclusions Increased atherogenesis may be one independent mechanism mediating the epidemiological link between impaired fetal growth and vascular disease.
