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.
