目的 分析山东省7~18岁青少年生长发育现状并绘制曲线图,比较不同经济地区的体格发育差异。方法 按地区经济水平将数据分为三组,比较各组身高、体重及超重、肥胖检出率。绘制出全省身高、体重第3、50、97百分位的曲线图,与中国儿童身高标准(CHN)及美国疾病预防控制中心(CDC)2000年标准(CDC标准)进行比较。结果 男女生身高、体重总体表现为发达地区高于欠发达地区及落后地区,除女生15岁组、16~18岁组身高外,其他年龄段差异均有统计学意义(P＜0.05)。山东省男女生在所有年龄段身高、体重均高于CHN 标准。男生身高在17岁之前,女生身高在13岁之前高于美国CDC标准,之后略低。结论 山东省青少年生长发育水平受经济等因素影响明显,山东青少年身高、体重明显高于CHN标准,在青春中晚期与CDC标准更接近。
Abstract
Objective To analyze the growth level of children and adolescents aged from 7 to 18 in Shandong Province and evaluate the development level between different regions. Methods Growth data for adolescents in various regions was differentiated and analyzed based on economic level of that area.Distribution tables that include heights,weights,overweight and obesity were made out;Graphs about the 3rd,50th and 97th percentiles of heights and weight were plotted;And results were compared with height and weight standardized growth chart for Chinese children and adolescents aged 0 to 18 years (CHN) and 2000 CDC Growth Charts for the United State. Results For both boys and girls,heights and weights increased with age.The height and weight in all age groups of developed regions were highest among developed regions,less-developed and underdeveloped regions.While the height and weights in all age groups of less-developed were higher than those of underdeveloped regions.The result was statistically significant (P<0.05) for all age groups except for girls in aged 15 groups and aged 16~18 groups.For both boys and girls,heights and weights in all age groups were higher than those in CHN.The height in boys before 17 and girls before 13 were higher than those in CDC. Conclusions The growth and development of adolescents in Shandong province are affected significantly by the economic level of that region.The overall heights and weights of adolescents in Shandong province are higher than thoae in CHN level,and data from middle and late stages of puberty are close to that of CDC standard.However,percentages of overweight and obesity are significantly high.
