①目的了解青岛市李沧区３～７岁儿童体格发育状况。②方法对３所幼儿园的１１３６名在园儿童进行体格检查，并用标准离差法与哈尔滨、北京、上海等９市１９８５年标准值及１９９６年青岛市市区测量值进行比较。③结果以９市儿童的身高、体质量、胸围、头围等为标准计算李沧区３～７岁儿童４项指标的平均Ｚ－ｓｃｏｒｅ，Ｓｚ分别是男童身高：１．３０３９，１．０６１７；体质量：１．４２１０，１．５１２０；胸围：０．８３４８，１．３１１９；头围：０．３２３０，１．２７６１．女童身高：１．３８５９，０．９８５３；体质量：１．３８２３，１．４７５２；胸围：０．５０００，１．２４６９；头围：０．３３８１，１．４１０６．儿童身高、体质量、胸围、头围均超过９市同指标的标准值，差异呈高度显著性（ｕ＝５．４８～３２．１７，Ｐ＜０．００１）。与青岛市市区相比，男女童的身高均大于市区（ｕ＝１０．５４，１１．９６Ｐ＜０．００１）；体质量与市区差异无显著性（ｕ＝１．４３，０．０２，Ｐ＞０．０５）；胸围和头围平均Ｚ－ｓｃｏｒｅ值均低于市区儿童（ｕ＝３．１９～５．６８，Ｐ＜０．０１）。④结论青岛市李沧区３～７岁儿童体型匀称，其营养状况与市区儿童相当
①Objectives To understand the physical development status of children aged 3-7 in Licang District of Qingdao City. Methods The physical examination was conducted on 1136 children in the three kindergartens and compared with the standard values of 1985 in nine cities of Harbin, Beijing and Shanghai and the urban survey of Qingdao in 1996 by the standard deviation method. Results The average Z-scores of four indicators of children aged 3-7 in Licang District were calculated based on the height, weight, chest circumference and head circumference of children in nine cities. Sz was the height of the boy: 1.3039,1. Body mass: 1.4210,1.5120; Bust: 0.8348,1.3119; Head circumference: 0.3230,1.2761. Girls height: 1.3859,0.9853; body mass: 1.3823,1.4752; bust: 0.5000,1.2469; head circumference: 0.3381,1.4106. The height, body weight, chest circumference and head circumference of children all exceeded the standard values of 9 indicators of the same city, the difference was highly significant (u = 5.48 ~ 32.17, P <0.001). Compared with urban areas in Qingdao, boys and girls were taller than those in urban areas (u = 10.54, 11.96 P <0.001); there was no significant difference in body mass and urban area (u = 1.43,0. 02, P> 0.05). The average Z-score of bust and head circumference were lower than that of urban children (u = 3.19-5.68, P <0.01). ④ Conclusion Licang District, Qingdao 3-7-year-old children were well-proportioned, and their nutritional status is comparable with that of urban children
