【摘要】：目的探讨土家族、苗族儿童青少年1985—2010年生长长期变化特点、规律和趋势,为改善和提高连片特困地区少数民族儿童青少年的生长发育水平提供依据。方法选取中国学生体质与健康调研中的土家族、苗族7~18岁中、小学生,分析其身高、体重、体质指数(BMI)、身高最大增长年龄(MIA-H)、体重最大增长年龄(MIAW)的增幅和不同阶段增速,并以18岁年龄组为个案计算成年身高的持续增长和性别差异。结果 1985—2010年,7~18岁土家族男、女身高平均增幅分别为3.38、3.22 cm,苗族男、女分别为3.88、3.60 cm;土家族男、女体重平均增幅分别为4.12、2.52 kg,苗族男、女分别为3.17、2.62 kg;土家族男、女BMI平均增幅分别为1.22、0.55 kg/m2,苗族男、女分别为0.71、0.61kg/m2;生长速度土家族呈现"前慢后快"特点,体格向"粗壮型"发展,苗族呈现"前快后慢"特点,体格向"细长型"发展,10~13岁儿童是超重、肥胖重点监测对象;MIA-H、MIA-W除苗男外提前0.40~3.98岁;18岁成年身高出现增长,但幅度大多数不大,"性差"不足13 cm。结论土家族、苗族儿童青少年生长长期趋势潜力比较大,土家族已步入快速阶段,呈加速趋势,苗族处于初期阶段,增长趋势有所减缓,生长长期趋势存在民族、性别差异。
[Abstract]:Objective to explore the characteristics, regularity and trend of long-term growth changes of Tujia and Miao children and adolescents from 1985 to 2010. Methods in order to improve and improve the growth and development level of minority children and adolescents in the area of special hardship in Lianping District, the Tujia nationality, the Miao nationality 718 years old and the primary school children aged 718 years, were selected to analyze their height and weight. The body mass index (BMI), the maximum age of height growth (MIA-HX) and the maximum age of weight increase (MIAWW), and the growth rate of adult height in the age group of 18 years were used to calculate the sustained growth of adult height and the gender difference. Results from 1985 to 2010, there were 718-year-old Tujia males. The average height increase of female was 3.38 ~ 3.22 cm, that of Miao male and female was 3.88 ~ 3.60 cm, that of Tujia male was 4.12 ~ 2.52 kg, that of Miao male was 3.17 ~ 2.62 kg, and that of Tujia male and female was 1.220.55 kg 路m2, and that of Miao male was 1.22 0.55 kg 路m ~ (2), respectively. The growth rate of Tujia women was 0.71 ~ 0.61kg / m ~ (2). The Tujia nationality had the characteristics of "front slow and fast", the physique developed to "strong type", the Miao nationality showed "front fast after slow", and the children aged 10 ~ 13 years old were overweight when their physique developed to "slender type". The adult height of MIA-HGMIA-W was increased from 0.40 to 3.98 years old and 18 years old, except for the male. Conclusion there is a great potential of long-term growth trend in Tujia nationality, Miao children and adolescents, but the range is not large and the "sex difference" is less than 13 cm. Tujia has entered a rapid stage, showing an accelerated trend, Miao is in the initial stage, the growth trend has slowed down, the long-term trend of growth there are ethnic, gender differences.
