军队疗养员运动状况与心血管疾病危险因素的调查（英文）

目的：了解运动与心血管危险因素之间的联系。方法：选择在广州疗养院疗养的750名军队在职或离退休干部作为调查对象,区分为运动组（488名）和非运动组（262名）。测量其血压、人体质量指数（BMI）、空腹血糖（FBS）、总胆固醇（TC）、甘油三酯（TG）、尿酸等心血管危险因素,通过问卷调查其运动方式、运动频率、每次运动时间及一日累计运动时间。结果：1.非运动组的收缩压、舒张压、BMI、FBS、TC、TG水平均显著高于运动组（P均〈0.05）,两组间年龄、高密度脂蛋白-胆固醇、低密度脂蛋白-胆固醇、尿酸水平差异无显著性（P均〉0.05）;2.（1）两组每次运动时间（≥30min、〈30min）、运动方式（步行、太极拳）的心血管危险因素异常率（简称危险率）无显著差异;（2）一日活动时间大于60min的危险率明显低于活动时间≤60min的（29.41%比45.59%,P〈0.05）;自感运动强度在11～15之间的危险率明显低于运动强度小于11级的（33.67%比44.64%,P〈0.05）;（3）运动频率≥3次/周的危险率显著低于运动频率〈3次/周的（31.47%比48.43%）、运动坚持时间10～19年的心血管危险率显著低于运动坚持时间〈10年的（28.83%比39.89%）,P均〈0.05。结论：1.运动组的心血管危险程度较低,心血管危险因素有叠加作用;2.中老年患者每日运动60min,自感运动强度11～15,运动频率≥3次/周,长期坚持有助于降低心血管病危险性。

Survey on exercise and risk factors for cardiovascular diseases in convalescents of Military sanatorium

Objective:To study relationship between exercise and risk factors for cardiovascular diseases.Methods:A total of 750 military cadres retired or on the job,who received convalescence therapy in Guangzhou sanatorium,were enrolled as survey subjects,and divided into exercise group(488 cases),and no-exercise group(262 cases).The cardiovascular risk factors such as blood pressure,body mass index(BMI),fasting blood glucose(FBS),total cholesterol(TC),triglyceride(TG)and uric acid were measured.Questionnaires were used to survey mode of exercise,exercise frequency,exercise duration each time and total exercise time in a day.Results:1.In no-exercise group,levels of systolic blood pressure,diastolic blood pressure,BMI,FBS,TC and TG were significantly higher than those of exercise group(P<0.05 all),but there were no significant difference in age and levels of HDL-C,LDL-C and uric acid between the two groups(P>0.05 all);2.(1) Abnormal rate of risk factors for cardiovascular diseases(call for short was risk rate,similarly hereinafter)in different exercise duration each time(≥30 min、<30 min)and exercise mode(walking,taijiquan)were no significant(P>0.05 all);(2)Risk rate in subjects who took exercise>60min in a day was significantly lower than that of those with ≤60min(29.41% vs.45.59%),in subjects whose exercise intensity with RPE(Borg rating of perceived exertion scale)11~15 was significantly lower than that of with RPE<11(33.67% vs.44.64%),P<0.05 all;(3)Risk rate in subjects whose exercise frequency ≥3 times/week was significantly lower than that of with<3 times/week(31.47% vs.8.43%),in subjects whose persistence time of exercise was 10~19 years was significantly lower than that of with<10 years,P<0.05 all.Conclusion:1.Risk extent of cardiovascular diseases is lower in exercise group,and there is additive effect in risk factor for cardiovascular diseases;2.take exercise>60min/d,Borg rating of perceived exertion scale 11~15,exercise frequency ≥3 times/week and long time persistence are conduce to decrease risk of cardiovascular diseases in middle-aged and aged persons.
