Abstract

OBJECTIVES

To analyze the growth trends of children in Beijing from 1955 to 2010.

METHODS

Data for the period 1955-1975 were derived from published records. Data for the period 1985-2010 were derived from the Chinese National Survey on Students' Constitution and Health (CNSSCH). Since 1985, the overall sampling and measurement methods have been consistent. The mean, the standard deviation, and the variance (ANOVA) of height, weight, and BMI by age and sex of students aged 7-17 were calculated and analyzed.

RESULTS

Between 1955 and 2010, the average height and weight of children in Beijing has increased. The average increments per decade for boys and girls were 2.45cm and 2.03cm in height and 2.68kg and 1.68kg in weight, respectively. The largest height increase per decade occurred between 1975 and 1985: 4.51cm and 3.23cm for boys and girls, respectively. The largest height increase for the entire 55-year period under study occurred among boys at age 13 (17.85cm) and among girls at age 11 (15.90cm.)

CONCLUSIONS

During the period 1955-2010, growth trends among children in Beijing were positive. The health and nutritional status of these children improved significantly. Since 2007, might be related to government intervention, childhood obesity has been curbed.

摘要

目的

分析1955年至2010年北京儿童的生长趋势。

方法

1955 - 1975年的数据来源于已发表的记录。1985 - 2010年的数据来源于中国国家学生体质与健康调研（CNSSCH）。自1985年以来，总体抽样和测量方法保持一致。计算并分析了7至17岁学生按年龄和性别的身高、体重及体重指数（BMI）的均值、标准差和方差（方差分析）。

结果

1955年至2010年期间，北京儿童的平均身高和体重有所增加。男孩和女孩每十年身高的平均增长量分别为2.45厘米和2.03厘米，体重的平均增长量分别为2.68千克和1.68千克。每十年身高增长最大的时期出现在1975年至1985年之间：男孩和女孩分别为4.51厘米和3.23厘米。在整个55年的研究期间，身高增长最大的是13岁男孩（17.85厘米）和11岁女孩（15.90厘米）。
