Objective To investigate the body composition of workers in a hospital in Xi′an and to analyze its relationship with different exercise intensities.Methods 188 cases of people were enrolled who underwent the physical examination and who wanted to further subject to body composition test in the first affiliated hospital of Xi′an Medical University,the DBA-210 analyzer was used to detect the human body composition,difference was statistically compared between gender,age,moisture,protein,inorganic salt,waist-to-hip ratio,and visceral fat.In addition,the difference in body composition was also analyzed between the male and female worker with different exercise intensity.Results The body weight,BMI,waist hip ratio,visceral fat,moisture,total protein,muscle mass,fat-free body weight of male workers were shown to be significantly higher than that of female workers(P<0.05),there was statistical difference of age in the total water,protein,inorganic salt,muscle mass,BMI,body fat rate,waist hip ratio and visceral fat(P<0.05),whereas no statistical difference of age was observed in total water,protein,inorganic salt,muscle mass and body fat ratio of female workers(P>0.05).But there was statistical difference of age in fat-free body weight,BMI,waist hip ratio,visceral fat of female workers(P<0.05),furthermore,there was an increasing trend with the increasing of age in the case of fat-free body weight,BMI,waist hip ratio and visceral fat of female workers.No statistically significant correlation was found between labor intensity and markers of body composition of male workers(P>0.05),while there was significant correlation between labor intensity and protein,muscle mass,fat-free body weight,BMI,body fat ratio,waist hip ratio and visceral fat of female workers(P<0.05).No significant correlation was observed between total water and inorganic salt of female workers(P>0.05).Conclusion Given that there was difference of age and gender in the body composition of workers in a hospital in Xi′an city,changing of unhealthy lifestyle and living behaviours was suggested.our study suggests that effective self-control over oneself could be preventive from the development of disease.%目的 了解西安市某医院职工人体成分及其与不同运动强度的关系.方法 选择参加西安医学院第一附属医院体检并自愿来营养科门诊做人体成分测定的188名职工,采用DBA-210人体成分分析仪进行人体成分检测,比较不同性别、不同年龄段职工总水分、蛋白质、无机盐、体脂肪、腰臀比、内脏脂肪等人体成分指标的差异,并分析不同运动强度下男、女职工人体成分的差异.结果 男职工的体质量、BMI、腰臀比、内脏脂肪、总水分、蛋白质、肌肉量、去脂体质量明显大于女职工,女职工体脂肪率明显大于男职工,差异均有统计学意义(P<0.05).男职工的总水分、蛋白质、无机盐、肌肉量、BMI、体脂肪率、腰臀比和内脏脂肪存在年龄差异(P<0.05).女职工的总水分、蛋白质、无机盐、肌肉量均不存在年龄差异(P>0.05),去脂体质量、BMI、腰臀比、内脏脂肪存在年龄差异(P<0.05),随着年龄增长呈上升趋势,体脂肪率不存在年龄差异.男职工组的运动强度和体成分各指标差异均无统计学意义(P>0.05),女职工组的不同运动强度和蛋白质、肌肉量、去脂体质量、BMI、体脂肪率、腰臀比、内脏脂肪差异均有统计学意义(P<0.05),总水分和无机盐差异无统计学意义(P>0.05).结论 西安市某医院职工人体成分存在性别和年龄差异,应积极指导职工改变不良的生活方式和行为,对自身健康进行有效的管理,从而预防相关疾病的发生.
