Analysis On Body Shape Dynamics Of 3-6 Years Old Children In Qinghai Province From 2000 To 2014

Body shape is the most intuitive direct response to the characteristics of the human body evaluation index.While the children 3 to 6 years of age is the first rapid growth and development stage of the human body,In the vertical,horizontal are faster development speed,But the rapid development of height and width in what circumstances is healthy development,need to use the body shape of the various indicators to conduct a comprehensive evaluation.Qinghai Province as a high altitude and high altitude multi-ethnic areas,children's growing environment is more special.Since the 1995 "National Fitness Program" promulgated,from 2000 onwards the provinces and cities nationwide to carry out every five years of national physical monitoring,as of 2014 to a total of 4 times.This study was done since 1995,surveillance Results of Infant 's Body Shape in National Physical Fitness Monitoring in Qinghai Province from 2000 to 2014,the use of mathematical statistics,logic analysis,modeling analysis,this paper summarizes the continuous dynamic changes of the young people in the body shape under the special geographical environment in Qinghai Province,make a reasonable evaluation of the past situation,establish the model to predict the future development trend,and compared with the national and mainland plains of the same age children to find out the advantages and disadvantages.Analysis conclusion: 1? From the overall situation,from 2000 to 2014,the basic shape indicators of young children in Qinghai Province,including height,weight,sit high,chest circumference are showing a gradual increase with the trend of increasing year,significant difference;to each year as a node,the performance of the increase young boys than young girls,while the average child is higher than the young children.In the reaction fat distribution and accumulation of the morphological indicators,including the upper arm skin fold,scapular skin folds,abdominal skin fold are showing with the increase in the first year after the first increase in the trend,in 2010 reached the lowest level,to each year as a node,the performance of young boys than young girls.2? From the urban and rural comparison point of view,the urban and rural population of each index showed a trend of increasing with the year,in addition to reaching the highest level in weight in 2010,decline in 2014 but still higher than the 2000 level,the remaining indicators are 2014 to reach the highest value.whether in the growth rate or the average value,are reflected in the town higher than the village,young boys than young girls.3 ? From the physical compliance rate,20 years in Qinghai Province,Children's physical compliance rateabove qualified,the overall trend with the year to increase the body getting better and better,and young boys physical pass rate slightly lower than the young girl;Physical compliance rate in the unqualified,overall presentation with the increasing number of years the trend is getting lower.To urban and rural physical compliance rate comparison point of view,the overall performance of the town is better than rural,but with the increase in years,the gap between urban and rural areas is getting smaller and smaller.4?Compared with the national level of the same age,in addition to Skinfold thickness higher than the national level,others are lower than the national average,which height,chest circumference,skinfold thickness of the three indicators of the gap is young boys more than young girls,other indicators young boys less than the gap between young girls.5 ? Through the mathematical modeling GM(1,1)to predict the future development trend of young children body shape in Qinghai Province,the prediction model is:X(m+1)=(-4281.67665)e0.014328(m-1)+4271.67665,the prediction accuracy is two favorable.Suggest: 1?Increase children's activities space and game equipment,especially to strengthen the rural children's activities infrastructure.2?In daily life,should pay attention to a reasonable diet and living habits,to promote children to the healthy direction of growth.3?Through diet and exercise can improve the body,promote bone,muscle rapid growth and brain development,but also should strengthen the training of children's activities to guide staff.4 ?
