【摘要】 用随机分层抽样方法，对７岁～１６岁广西玉林地区博白、陆川两县１１３５名中、小学生体质发育２３项指标测量调查。选身高、躯干长、上肢长、下肢长进行男女学生对比，结果男女生的发育趋势一致，但突增期不同（男１０岁～１１岁，女１２岁～１３岁）。对上肢长／身高指数分型，发现男女生的上肢长／身高指数均集中在短型（分别为９８．０％，９８．２％）；对下肢长／身高指数分型，发现男女生的下肢长／身高指数多在长型（男５８．５％，女４３．５％）和短型（男３３．６％，女４３．１％）。与全国和日本的身高资料对比，该地区学生身高最低；男性的最大差值分别为９０．７ｍｍ（１６岁），１２０．６ｍｍ（１６岁）；女性的最大差值分别为５７．８ｍｍ（１６岁），８６．１ｍｍ（９岁）。更多还原

【Abstract】 By random stratified sampling,1 135 students (645 males and 490 females) at the age of 7 to 16 were investigated at 32 anthropometry items in counties Bobai, Luchuan of Yulin prefecture, Guangxi. The growth tendency of body height, trunk length, upper extremity length, lower extremity length between the male and the female are in line, but their fast growth phases are different, male in age of 10 to 11,female in 12 to 13. According to typing by upper extremity length/body height , the short type accounts for 98 0% for male and 98 2% for female in all the three types; and according to typing by lower extremity length/body height, the long type is 58 5% for male,43 5% for female; the short type is 33 6% for male ,43 1% for female. The body height average of the students in Yulin prefecture is the lowest compared to the whole country and Japanese students and the maxmium difference is respectively 90 7 mm(age 16),120 6 mm(age 16) to male;57 8 mm (age 16),86 1 mm (age 9) to female.更多还原
