腰围身高比评价湖北省少数民族地区老年人身体成分的可行性

Feasibility of waist-to-height ratio to evaluate the body composition of people aged 60-69 years in Hubei minority areas

目的探讨腰围身高比（WHtR）反映湖北省少数民族地区60～69岁老年人身体成分的可行性。方法在湖北省少数民族地区采用分层抽样法随机抽取60469岁老年人398例，测试受试对象的身高、体质量、腰围、臀围和上臂部、肩胛部及腹部的皮褶厚度，然后采用Bland—Altman图比较WHtR与体质指数、腰臀比和铃木一长岭公式的一致性。结果对测试数据进行标准化后发现评价方法WHtR与体质指数的平均值为0．007，WHtR与腰臀比的平均值为0．007，WHtR与铃木一长岭公式的平均值为0．711，表明WHtR与体质指数、腰臀比和腰臀比有较好的一致性。结论WHtR可作为该地区反映60469岁老年人身体成分的典型指标。

Objective To evaluate the feasibility of waist-to-height ratio （WHtR） to reflect the body comPosition of people aged 60-69 years in Hubei minority areas. Methods A total of 398 eligible residents between 60-69 years old were selected through a stratified sampling method. Body height, weight, waist circumference, hip circumference and skinfold thickness were measured at the interview. Bland-Altman analysis was applied to estimate the consistency among WHtR, body mass index （BMI）, waist-to-hip ratio （WHR）, and Suzuki-changling formula. Results After standardization, the mean of WHtR and BMI was 0. 007, the mean of WHtR and WHR was 0. 007, and the mean of WHtR and Suzuki - changling formula was 0. 711, which revealed that there were good consistency among WHtR, BMI, WHR and Suzuki-changling formula. Conclusions WHtR may serve as an typical index to reflect the body composition of people aged 60-69 years in Hubei minority areas.
