【摘要】：目的分析甘肃裕固族成人骨强度和体成分随年龄变化特征并探讨骨强度与体成分的相关性。方法2015年7月至2016年8月选取甘肃省肃南裕固族自治县成人725例(男性354例,女性371例),年龄20~86岁,采用超声骨密度仪和生物电阻抗分析仪,分别测量跟骨骨强度及体成分指标。结果甘肃裕固族成年男性骨强度在20~29岁低于女性(P0.05),50岁后高于女性(P0.01);男性各年龄段的肌肉量均高于女性(P0.01);各年龄段的总脂肪量、皮下脂肪含量均低于女性(P0.01);内脏脂肪含量仅在20~29岁及70岁后低于女性(P0.01)。男女骨强度分别在30~39岁和20~29岁达峰值、50~59岁和40~49岁开始较前出现差异(P0.05),男性在70岁后和女性在50岁后骨强度低于之前各年龄组(P0.01)。男性躯干及四肢肌肉量均在40~49岁及60~69岁呈现双峰,女性躯干及四肢肌肉量均在40~49岁达峰值。甘肃裕固族成年身体各部位的脂肪含量变化同步,男女性分别在60~69岁和50~59岁达峰值。多元线性逐步回归分析显示,骨强度与四肢肌肉量和皮下脂肪量正相关(P0.01),与内脏脂肪量负相关(P0.01)。结论随年龄增长,甘肃裕固族成人身体各部位的同种体成分呈同步变化,女性骨强度较男性下降时间早且速度快。裕固族成人骨强度由肌肉和脂肪共同决定且与其分布部位有关。裕固族70岁以上男性及50岁以上女性是骨质疏松性防治的重点人群;男女性应分别从50岁后和40岁后应加强肢体锻炼、增加四肢肌肉量、控制内脏脂肪,预防骨质疏松。
[Abstract]:Objective to analyze the changes of bone strength and body composition with age and to explore the correlation between bone strength and body composition in Yugur adults in Gansu province. Methods from July 2015 to August 2016, 725 adults (354 males and 371 females), aged 20 to 86 years, were selected from Yugur Autonomous County, Sunan, Gansu Province. Ultrasound absorptiometry and bioelectrical impedance analyzer were used. Calcaneal bone strength and body composition were measured. Results the bone strength of Yugur adult male was lower than that of female at 20 ~ 29 years old (P0.05) and higher than that of female after 50 years old (P0.01), and the muscle mass of male was higher than that of female (P0.01). The total fat content of each age group was lower than that of the female (P0.01), and the visceral fat content was lower than that of the female at the age of 2029 and 70 (P0.01). The bone strength of male and female reached the peak at 30 ~ 39 years old and 20 ~ 29 years old respectively. There was a difference between 50 ~ 59 years old and 40 ~ 49 years old (P0.05). The bone strength of male after 70 years old and female after 50 years old was lower than that of every age group before (P0.01). Male torso and extremities muscle volume showed double peak at 4049-year-old and 60-69 years old, and female torso and extremity muscle volume peaked at 400-49 years old. The body fat content of Yugur nationality in Gansu changed synchronously, the peak of male and female reached its peak at the age of 6069 and 50 ~ 59, respectively. Multiple linear stepwise regression analysis showed that bone strength was positively correlated with limb muscle and subcutaneous fat (P0.01) and negatively correlated with visceral fat (P0.01). Conclusion with the increase of age, the allogeneic components of Yugur adults in Gansu Province changed synchronously, and the bone strength of females decreased earlier and faster than that of males. Bone strength of Yugur adults is determined by muscle and fat and is related to its distribution. The male and female over 70 years old and over 50 years old are the key people in the prevention and treatment of osteoporosis, and the male and female should strengthen the limb exercise, increase the muscle quantity of the limbs, control the visceral fat and prevent the osteoporosis from 50 years old and 40 years old respectively.
