摘要
目的:了解广西马山瑶族成年人体成分的年龄变化和性别差异,为对瑶族群体疾病的预防和控制提供参考数据。方法:用生物电阻抗法测定广西马山瑶族成年人的身体组成分,共检测841例,其中男350例,女491例。体成分指标包括体重、去脂体重、脂肪量、内脏脂肪量、皮下脂肪量、躯干脂肪量、四肢脂肪量、体脂率、体质指数、指定骨量、肌肉量、蛋白量、身体水分、细胞内液、细胞外液、腰臀比。结果:广西马山男性成人去脂体重、肌肉量、推定骨量、蛋白质、身体水分等非脂肪指标均高于女性,而女性脂肪量、体脂率、皮下脂肪量、躯干脂肪量、四肢脂肪量等脂质指标均高于男性(P<0.01)。广西马山瑶族成年男性的体重、去脂体重、推定骨量、脂肪量、细胞外液、皮下脂肪、内脏脂肪含量、四肢脂肪、躯干脂肪含量、体脂率、体质指数、腰臀比等随年龄增大而增大,到50~59岁达到最大,60~以后这些指标出现随年龄增大而减小的趋势。而肌肉量、蛋白质、身体水分、细胞内液随年龄增大而减小。广西马山瑶族女性的体重、脂肪量、推定骨量、肌肉量、身体水分、细胞外液、细胞内液、内脏脂肪含量、皮下脂肪量、躯干脂肪量、四肢脂肪量、体质指数、体脂率呈先升,到达峰值后再降的趋势。其中,体重、脂肪量、推定骨量、肌肉量、身体水分、细胞内液、皮下脂肪量、四肢脂肪量、体质指数到达峰值的时间是40~49岁年龄段;细胞外液、内脏脂肪含量、躯干脂肪量、体脂率比达峰值的时间是50~59岁。腰臀比率随着年龄增大而增大。去脂体重、蛋白质、细胞内液、肌肉量随年龄增大而减小。结论:广西马山瑶族成年人群体成分存在明显的性别差异;各项体成分指标随年龄的增大而变化,老年人群的各项体成分指标随着年龄的增长而呈下降趋势。
Objective:To investigate the age changes and gender differences of adult body composition of the Yao nationality in Mashan, Guangxi, so as to provide reference data for the prevention and control of diseases in the Yao population.Methods: The body compositions of 841 adults of Yao nationality in Mashan, Guangxi were determined by bioelectrical impedance method, including 350 males and 491 females. Body composition indexes include body weight, fat-free weight, fat weight, visceral fat volume, subcutaneous fat volume, trunk fat volume,limb fat volume, body fat rate, body mass index, designated bone mass, muscle mass, protein content, body moisture, intracellular fluid, extracellular fluid, and waist-to-hip ratio.Results: The non-fat indexes such as fat-free body weight, muscle mass volume, presumed bone mass, protein and body moisture of male adults were higher than those of females.The fat weight, body fat rate, subcutaneous fat volume, trunk fat volume and limb fat volumeof females were higher than those of males(P<0.01). The body weight, fat-free body weight, presumed bone mass, fat content, extracellular fluid, subcutaneous fat volume, visceral fat volume, limb fat volume, trunk fat volume, body fat rate, body mass index, and waist-to-hip ratio of adult males were increased with age,theyreached the maximum at the age of50 to 59 years old, and after 60 years old, these indexes showed a trend of decreased with age;however, the muscle mass, protein, body water, and intracellular fluid decreased with age. The body weight, fat weight, presumed bone mass, muscle mass, body moisture, extracellular fluid, intracellular fluid, visceral fat volume, subcutaneous fat volume, trunk fat volume, limb fat volume,body mass index, and body fat rate of womenwere increased first and then decreased after reaching the peak;among these indexes, the peak time of body weight, fat volume, presumed bone mass, muscle mass, body moisture, intracellular fluid, subcutaneous fat volume, limb fat volume, and body mass index was 40 to 49 years
