摘要:
[目的]探讨久坐对非体力劳动健康成年人血管功能状况的影响.[方法]将受试对象分为成年甲组20~39岁,成年乙组40~59岁等组别.采用文献资料法、问卷调查法、实验法对受试者血管功能指标进行相关分析研究.主要测定指标包括血流介导的舒张(FMD)、颈动脉内膜-中层厚度(CIMT)、心踝血管指数(CAVI)、踝臂指数(ABI).[结果]1)年龄与CIMT,CAVI呈显著正相关(P<0.05).2)男性CIMT平均值均显著大于女性(P<0.05).3)久坐与非久坐人群的各项血管功能指标平均值差异均不显著(P>0.05).4)静态活动时间与各项血管功能指标之间均无显著相关性(P>0.05).5)只有成年乙组在未控制每周运动时间的情况下,其静态活动时间与ABI存在显著相关性(P<0.05).6)FMD与CAVI之间呈显著负相关(P<0.05);CIMT与CAVI之间呈显著正相关(P<0.01);CIMT与ABI,CAVI与ABI之间呈显著正相关(P<0.05).[结论]1)性别是血管功能CIMT指标的影响因素;年龄是CIMT,CAVI指标的独立影响因素.2)久坐与非久坐人群各项血管功能指标差异均不显著,但增龄性改变导致血管功能ABI指标对静态活动时间及每周运动时间的敏感性逐渐提高.成年乙组静态活动时间越长,心血管病变的风险越高.
[Objective]The effects of sitting on vascular function of non-physical healthy adults were discussed.[Method]165 non-manual workers were recruited as subjects.They were divided into Group A(20-39 years old)and Group B(40-59 years old).Literature,questionnaire and experimental methods were used to analyze the vascular function indicators of the subjects.The main measurement indicators included flow-mediated dilation(FMD),carotid intima-media thickness(CIMT),cardio-ankle vascular index(CAVI),ankle-brachial index(ABI).[Result]1)There was a significant positive correlation between age and CIMT and CAVI(P<0.05).2)The average CIMT of adult group A and adult group B was significantly greater in males than that in females(P<0.05).3)The mean values of vascular function indexes between sedentary and non-sedentary people were not significantly different(P>0.05).4)There was no significant correlation between static activity time and various vascular function indexes(P>0.05).5)Only in adult group B,there was a significant correlation between the static activity time and ABI when the exercise time per week was not controlled(P<0.05).6)There was a significant negative correlation between FMD and CAVI(P<0.05);a significant positive correlation between CIMT and CAVI(P<0.01);a significant positive correlation between CIMT and ABI(P<0.05);a significant positive correlation between CAVI and ABI(P<0.05).[Conclusion]1)Gender is the influencing factor of CIMT index of vascular function;age is the independent influencing factor of CIMT and CAVI index.2)There was no significant difference between sedentary and non-sedentary people in various vascular function indicators,but aging changes led to the gradual improvement of the sensitivity of ABI indicators of vascular function to static activity time and weekly exercise time.The results show that the longer the static activity time in Group B is,the more the risk factors of cardiovascular disease there are.
