Research objectives：It is good for controlling the body fat within the certain range by figuring out itscontents and distributing features of the Miao students aging from12to14years old inShaoyang. It can keep weight between the fat body and the fat-free boy within a suitableproportion between，thereby decreasing the onset risks of the relative diseases. In themeantime，the investigation into the influencing factors of the BF distribution on theMiao students(12to14years old) in this area can provide targeting instructions andsuggestions with their future growth as well as providing certain references on how toimprove their health and living qualities.Research objects and methods：To randomly sample600Miao students aging from12to14in Shaoyang City andmeasure their height，weight，skinfold thickness (including the scapular parts，abdomen，the upper arms，thighs and lower legs etc.) and the body fat rate. The questionnaireshave been also sent out，which can help us figure out the influencing factors of the Miaostudents’somatotype from the following aspects，such attitudes towards health，lifestyle and physical activities and so on. The measured data and investigatedinformation are both analyzed by adopting SPSS.Results：1.Height and weight of the Miao students in Shaoyang City (years from12to14)are gradually increasing with their growth of age. And whether boys or girls at the sameage，the urban students are taller than the rural ones；urban boy students are taller thanurban girl students; the same is true with the rural boy and girl students.2.For the students as above-mentioned，body fat increase in urban ares is slightlyhigher than that of rural areas in comparison with the same gender between the urbanand the rural in Shaoyang，but there isn’t any obvious difference (P>0.05). With thegrowth of age，both male and female students’ body fat is on the gradual increase，andthe skinfold thickness reaches the maximum at the age of14. BF rate in the town ishigher that of the countryside，and that of girls are higher than that of boys. Furthermorefat storage in girls’ thighs and abdomens is apparent.3.The average obesity of the male Miao students(the same age with the above) hasbeen tested to be5.46%，that of the girls is4.54%； while the skinfold thickness of girlsis obviously higher than that of boys in each parts (boys：p<0.05) whether they are fromthe town or the countryside，and the thickness of students from the urban is generallyhigher than that of the rural. 4.In Shaoyang，both the Miao boys and girls aging from12to14，theirsomatotype(such as over-thinness， normal， over-weight and obesity) has closeconnection with their living and eating habits and daily physical activities，mainlybecause of preferring meat，snacks，fried cooking，sitting still but little movement，littleexercise and small-strength one etc.5.Logistic regression shows the influencing factors of over-weight and obesity forthe students above-mentioned mainly cover as below：urban and rural, kinds of thestaple food，snack types，physical exercise and its strength or time and so on.6.In Shaoyang，the self sensation of the Miao students (year12-14) toward theirbody components and health consciousness has positive correlation with theirsomatotype. Approaches are diversified for students to obtain health knowledge，whichmainly come from their teachers，books and family education.Conclusion:1.
