宁夏南部山区部分行政村居民人体成分水平与亚健康状况分析

Analysis of Human Composition Level and Subhealth Status of Residents in Some Administrative Villages in Southern Mountainous Areas of Ningxia

目的了解宁夏南部山区农村居民人体成分的变化和亚健康率,为农村居民的健康指导提供理论依据。方法采用Inbody770型体成分分析仪,对宁夏南部山区(固原原州区、西吉县和海原县)农村居民进行人体组成成分测定,指标为Inbody评分、身体总水分(TBW)、细胞内水分(ICW)、细胞外水分(ECW)、蛋白质(Pro)、无机盐(IS)、瘦体重(FFM)、脂肪含量(BFM)、骨骼肌含量(SMM)、基础代谢率(BMR)、肌肉含量(SLM)、骨矿物质含量(BMC)等。结果不同性别和年龄组TBW、ICW、ECW、Pro、IS、BFM、SLM、FFM、SMM、BMC、BMR指标比较,差异均有统计学意义(P均<0.05),其中女性BFM随着年龄增加而增加,在50~59岁达到高峰后下降;男性BFM随着年龄增加而增加,在30~39岁达到高峰后下降。男性与女性的总体亚健康率分别为55.3%和50.6%,不同年龄组的女性亚健康率和总体亚健康率比较,差异均有统计学意义(P均<0.05)。结论人体成分指标的变化与性别和年龄有关,脂肪含量的变化趋势最为显著,处于亚健康状态的人群普遍存在。整体来看,宁夏南部山区农村居民健康状况有待改善。

Objective To understand the changes in body composition and sub-health rate of rural residents in the southern mountainous areas of Ningxia,and to provide a theoretical basis for rural residents'health guidance.Methods The body composition of rural residents in the southern mountainous areas of Ningxia(GuYuan District,XiJi County and HaiYuan County)was determined by the Inbody 770 body composition analyzer.The indicators were Inbody score,total body water(TBW),and Intracellular water(ICW),extracellular water(ECW),protein(Pro),inorganic salts(IS),lean body mass(FFM),fat content(BFM),percentage of body fat(PBF),skeletal muscle content(SMM),basal metabolic rate(BMR),muscle mass(SLM),bone minerals Content(BMC),etc.Results The differences of TBW,ICW,ECW,Pro,IS,BFM,SLM,FFM,SMM,BMC and BMR in different genders and age groups were statistically significant(P all<0.05).Female fat increased with age and decreased after reaching the peak at 50-59 years old.Male fat increased with age and decreased after reaching the peak at 30-39 years old.The overall sub-health rates of males and females were 55.3%and 50.6%,respectively.The overall sub-health rate and sub-health rate of women in different age groups were statistically significant(P all<0.05).Conclusion The change of body composition index is related to sex and age,and the change trend of fat content is the most significant,and people in sub-health state are widespread.Overall,the health status of rural residents in the southern mountainous area of Ningxia needs to be improved.
