| Purpose: to study the gansu han into the human body composition distribution and change characteristics,comparison of gansu han adult body composition differences between male and female gender,analysis of different regions in gansu province han into the trend of the human body composition changes along with the age,physical health level of evaluation of gansu province han nationality adults,to help the local relevant prevention and treatment of chronic diseases,and provide theoretical basis for the improvement in the population health.Methods: random cluster sampling method,selection of linxia,gansu province,lanzhou,alkaline saline respectively three areas between 20 to 80-year-old han adult residents as the research object,investigated 1959 people(male 725,female725).By means of questionnaire survey,living measurement,bioelectrical impedance and human component detection,the data of human body composition was obtained and database was established.SPSS20.00 statistical software was used to analyze the test results.Results:1.the comparison of the same area and sex,the male in BMI,lean body mass,muscle mass,body moisture,protein,minerals,fluid in the cell,extracellular fluid,visceral fat area,waist hip ratio,basal metabolism,trunk muscle mass,left upper limb muscle mass,the left leg muscle mass,right upper limb muscle mass,16 indicators on the right lower limb muscle mass than women,the swelling index,body fat and subcutaneous fat content,body fat,left upper limb body fat,arm fat right,the left leg fat,right leg fat mass,body fat rate,body fat rate,left upper body fat rate,right upper body fat rate,the left leg fat rate,14 indicators on the right lower limb fat rate lower than that of women.2.male adult compared three regions,except the swelling index indicators,various body composition indexes of lanzhou is higher,the BMI,lean body mass,muscle mass,body moisture,protein,minerals,extracellular fluid,trunk muscle mass,body fat,body fat rate,visceral fat area,visceral fat,subcutaneous fat,waist hip ratio,body fat,left upper limb fat,the left leg fat mass,the left leg fat rate,right upper right lower limbs fat,fat mass,the right lower limb 13 body fat rate component index show the lowest linxia.Intracellular fluid,basal metabolism,left upper limb muscle mass,leftlower limb muscle mass and right lower limb muscle mass index were the highest among men in zhangye city.Body fat rate,left upper body fat rate and right upper limb fat rate were the lowest in the city of linxia.Female adult compared three region,fat mass,body fat rate,visceral fat area,visceral fat content,subcutaneous fat content,body fat,the left leg fat rate,right upper limb right lower limbs fat,fat mass,the right lower limbs fat rate,BMI,lean body mass,muscle mass,mineral fluid in cells,basal metabolism,left upper limb muscle mass,the left leg muscle mass,the right lower limb muscles,body fat rate,left upper body fat rate,right upper body fat rate of 22 show the highest,zhangye women linxia city is low,the highest swelling index,index of lanzhou city women.3.three regions of human body composition changes along with the age is different,the indicators of lanzhou male fat and subcutaneous fat content is significantly higher than the other two areas,the peak at the age of 40,followed by a downward trend;Lanzhou city male body fat rate,visceral fat content is significantly higher than the other two regions,the trend of increasing with age,lanzhou women lean body mass,muscle mass,minerals,body moisture peak at the age of 40,after the downward trend,other indicators have increasing trend along with the age.The lean body weight,muscle mass,body water,protein content and mineral content of men in linxia city reached their peak at the age of 30,and other indicators were all increasing with age.Women are close to men,but their fat content and distribution are different from men’s,and they tend to fall after the age of 50.In zhangye city,male protein decreased with age,and the edema index increased with age,and other indexes peaked at age 50,then gradually decreased.Men and women are different,in muscle mass,lean body mass,minerals,such as body moisture distribution of limb muscle after peak decline at the age of 40,other indicators have has a tendency to increase gradually with age.There were statistically significant differences between the 31 component indexes of male and female in the three fields,with the overall performance being the highest in lanzhou city,the lower in zhangye city and the lower in linxia city.The comparison of female body composition in the three regions showed no statistically significant difference in the amount of fluid,visceral fat,subcutaneous fat and right lower leg muscle mass,and the other overall performance was the highest in zhangye city and the lowest in the last few years.Conclusion:1.There is a gender difference in body composition index,except for the fat content,subcutaneous fat and fat content of the extremities,the female is higher than the male,and the other males are higher than the females.The index of male body composition in lanzhou city is the highest,and the female body component index of zhangye city is the highest.Three male,the female body composition in each index change with age,male,the female body component age changes in lanzhou city and zhangye close to peak at the age of 40 and 50 years old respectively,linxia city peak at the age of 30.2.The ratio of muscle mass ratio in lanzhou was the best,but the rate of obesity,the abnormal rate of body fat,the abnormal rate of visceral fat and the ratio of waist-to-hip ratio were the highest.The women in zhangye city had the highest fat content and high obesity rate.The group components of linxia group were low,and the peak muscle mass was 30 years old.3.three areas of lanzhou city,zhangye adult overweight and obesity rate is high,the high incidence of chronic diseases,suggest increase the exercise,reduce lipid and carbohydrate intake,changes in eating habits,and increase the intake of vegetables,fruit,reducing the occurrence of slow disease. |
