The aim of the study was to compare the efficiency of bioelectrical indices (percentage body fat, PBF; visceral fat index, VFI) and various anthropometric measures (body mass index, BMI; waist circumference, WC; waist-to-height ratio, WHtR) on determining hypertension in Chinese.
We conducted the community-based cross-sectional survey during August of 2013 to August of 2015 in 66 sample sites selected by multistage random sampling method from Henan province. 14,364 residents were included in the study.
In both genders, VFI and PBF tended to rise with age. However, for each age-specific group, men consistently had significantly greater VFI than women (all P<0.0001) and women had considerably higher PBF (all P<0.0001). The odds ratios and area under the ROC curves (AUCs) for hypertension associated with adiposity indices decreased with age. In younger (15~34year) men and women, VFI had the highest crude (2.43-7.95) and adjusted (2.40-11.63) odds ratio for hypertension. The AUCs for PBF, VFI and WHtR were significantly larger than those for BMI and WC (all P<0.01). Whereas no statistically significant difference were found in AUCs among PBF, VFI and WHtR (all P>0.10). Additionally, VFI and PBF yielded the greatest Youden index in identifying hypertension in men (0.27) and women (0.34), respectively. Optimal cutoffs for VFI/PBF were 11.70/24.45 and 7.55/33.65 in men and women, respectively.
VFI and PBF could be better candidates for identifying hypertension in men and women, respectively. Adolescents and young adults should be highlighted in preventing hypertension by control of excess body and visceral fat.
本研究旨在比较生物电指标（体脂百分比，PBF；内脏脂肪指数，VFI）和各种人体测量指标（体重指数，BMI；腰围，WC；腰高比，WHtR）在中国人群中确定高血压的效率。
我们于2013年8月至2015年8月期间，采用多阶段随机抽样方法，在河南省选取66个样本点进行了基于社区的横断面调查。14364名居民纳入本研究。
在男女两性中，VFI和PBF均随年龄增长而升高。然而，在每个特定年龄组中，男性的VFI始终显著高于女性（所有P<0.0001），而女性的PBF则显著更高（所有P<0.0001）。与肥胖指数相关的高血压的比值比和ROC曲线下面积（AUC）随年龄降低。在年轻（15~34岁）男性和女性中，VFI对于高血压的粗比值比（2.43 - 7.95）和调整后比值比（2.40 - 11.63）最高。PBF、VFI和WHtR的AUC显著大于BMI和WC的AUC（所有P<0.01）。而PBF、VFI和WHtR之间的AUC未发现统计学显著差异（所有P>0.10）。此外，VFI和PBF在男性（0.27）和女性（0.34）中识别高血压时产生的约登指数最大。男性和女性VFI/PBF的最佳截断值分别为11.70/24.45和7.55/33.65。
VFI和PBF分别可能是识别男性和女性高血压的更好指标。应通过控制身体和内脏脂肪过多来预防青少年和年轻人的高血压。
