摘要
目的探讨广西瑶族中老年人体脂的分布情况,分析脂肪率（ PBF）和体重指数（ BMI）的关系,为瑶族中老年人的肥胖诊断提供依据.方法随机抽取403名（男性162名,女性241名）广西瑶族健康中老年人作为研究对象,检测受试者的PBF和 BMI.结果广西瑶族中老年人各年龄段女性PBF均高于男性,差异有统计学意义（P〈 0. 01）;而女性BMI除45-年龄段低于男性外,其他各年龄段与男性比较差异无统计学意义（P〉0.05）;男性的PBF 和BMI在55岁后呈下降趋势,女性的PBF和 BMI在5 0岁后呈下降趋势;除55-年龄段外,男性在其他年龄段PBF 肥胖检出率明显低于女性（P〈0.05）,而男女性各年龄段的BMI肥胖检出率比较无统计学意义（P〉0.05）;瑶族中老 年男女以PBF和BMI判断的肥胖率存在显著相关性和明显的一致性.结论 PBF比单纯BMI更能反映人体肥胖的实际情况,能更准确地为瑶族中老年人肥胖的诊断提供依据.
Objective To explore the distribution of body fat in middle-aged and aged Yao people in Guangxi, analyze re- lation between percentage of body fat（ PBF） and body mass index（ BMI）,so as to provide evidence for diagnosis of obesity a-mong middle-aged and aged Yao people. Methods 403 healthy middle-aged and aged Yao people（ 162 males and 241 fe-males） were selected to this study.And their PBF and BMI were detected. Results The PBF of the females in each age group was all higher than that of the males among middle-aged and aged Yao people in Guangxi, difference was statistically signifi- cant（ P 〈0.01）.How- ever,except BMI of females aged 45 or above was low-er than that of the males, difference of BMI of fe-males and males in each age group was not statistically significant（P 〉0.05）.PBF and BMI of males began to decline after the age of 55,while those of the females began to decline after the age of 50.Except 55 years old or above, PBF detection rate of obesity of males in other age group was significantly lower than that of the females（P 〈0.05） , and difference of BMI detection rate of obesity among males and females in each age group was not statistically significant（ P 〉0.05）.0besity rates of middle- aged and aged Yao males and females which were judged by PBF and BMI have significant relation and obvious consistency. Conclusion Compared with simple BMI, PBF is a more practical way to reflect actual situation of obesity, it can provide di-agnostic reference more accurately for obesity of middle-aged and aged Yao people.
