摘　　要：目的探讨血管迷走性晕厥(VVS)患者与身高、体质量及人体质量指数(BMI)的关系。方法2001-01～2007-08在中南大学湘雅二医院晕厥专科门诊就诊或住院的不明原因晕厥(UPS)或先兆晕厥患者418例,经直立倾斜试验(HUTT)检查阳性诊断为VVS,其中4～17岁[平均(11·37±2·99)岁]223例(儿童组),18～70岁[平均(36·82±13·64)岁]195例(成人组)。测量身高、体质量,计算BMI。结果成人组HUTT阳性患者、HUTT阴性患者BMI在头晕组稍高于晕厥组(P>0·05);HUTT阴性组较HUTT阳性组BMI及体质量明显增高(P<0·01),两组身高比较差异无统计学意义(P>0·05)。儿童组BMI在各年龄段HUTT阴性组与HUTT阳性组比较差异均无统计学意义(P>0·05)。儿童HUTT阳性组或HUTT阴性组BMI与年龄均呈直线相关,两组直线回归显示,16岁以下儿童BMI在HUTT阴性组高于HUTT阳性组,16岁以上则呈相反变化。结论成人低体质量和低BMI者晕厥易感性增加,儿童BMI与晕厥易感性相关不密切。Objective To explore the relationship of the height, weight and body mass index （ BMI） with vasovagal syncope （ VVS）. Methods 418 out - patient and in - patient cases in the Second Xiangya Hospital, Central South University from January 2001 to August 2007 with unexplained syncope or prodromata [223 children, 4 - 17 years old, mean （ 11.37 ± 2.99） years old;195 adults, 18 -70 years old, mean （36.82 ± 13.64） years old] were enrolled in this study. Head - up tilt table test （HUTT） was performed in all the subjects, if the result was positive, the patient was diagnosed as vasovagal syncope. To measure their height and weight and to calculate the body mass index. Results （1）In HUTT positive or negative adults patients, BMI was higher in the patients with dizziness symptom than in those with syncope symptom （P 〉 0.05 ）. The HUTT negative group of adults subjects got a higher BMI and weight than HUTT positive group （ P 〈0.01 ） , but there were no significant differences in height （ P 〉 0.05 ）. （2）In children group, BMI at every age stage had no differences between the HUTT negative group and the HUTT positive group （ P 〉 0.05 ）. There was a marked linear correlation between BMI and age in both the HUTT negative and positive groups, the two groups linear regression showed that HUTT negative group got a higher BMI than the positive group when the age of the subjects were under 16 years old, but lower when the age above 16years old. Conclusions Adults who have lower body weight and lower BMI level get a higher susceptibility to syncope, and the BMI level of children may have some effect on syncope.
