成年人体重指数、脂肪分布、脂肪含量的监测及分析

目的调查成人超重、肥胖的发生率，探讨体重指数（BMI）、体脂百分比（PBF）、腰臀比（WHR）与超重、肥胖之间的关系。方法对111名成人用InBody3．0人体成分分析仪随机进行人体成分测试，分析他们体重指数、体脂分布、体脂百分比情况。结果男女超重率63．06％，肥胖率19．82％。男女腰臀比及体脂肪比率超标分别占70．27％、72．07％。不同BMI和不同年龄的男性和女性腰臀比都有显著性差异（P〈0．01）。不同BMI男性体脂百分比有显著差异（P〈0．05），女性有显著性差异（P〈0．01）。不同年龄男性和女性体脂百分比有差异（P〈0．05）。结论体重指数的增加主要是脂肪增加造成的，而体内的脂肪又主要堆积在腹部。超重、肥胖情况较严重、体脂分布不合理、体内脂肪含量过高需引起重视，应采取各种措施以减少由超重带来的一系列问题。

Monitoring and analyzing the BMI, WHR and PBF in adults

Objective One aim is to explore the incidence rate of overweight and obesity in adults and old people.Another aim is to research the correlation between the measurements of body mass index(BMI),waist-to-hip ratio(WHR),percent body fat(PBF) and the symptoms of overweight and obesity. Methods The body mass index(BMI),the body fat distribution and the proportion of belly fat of 111 adults and old people were tested by In Body3.0 human composition analysis instrument.(Results For) the male patients and the female patients,63.06% and 19.82% interviewers were overweight and obese,respectively.For the male patients and the female patients,the ratios of the interviewers whose WHR and PBF exceeded the normal indexes were 70.27% and 72.07%,respectively.The WHR of the male and female interviewers with different BMI and different ages had significant differences(P<(0.01).) The PBF of the male patients with different BMI had significant differences((P<0.05),) and the PBF of the female patients had significant differences(P<0.01). The PBF of the male and female patients with various ages had significant differences(P<0.05).Conclusions The increase of BMI results from the increase of fat, while the body fat mainly accumulates in the abdomen.The study suggests that overweight and obesity,inappropriate fat distribution and the high body fat content are serious issues of the adults and the old people.People should take measures to lose weight and solve a series of problems caused by overweight and obesity.
