Objective To establish a method for fast construction of child growth curve by SPSS software. Methods The data of 17 721 children from Shanghai were extracted from the data base of a cross-sectional survey of children aged 0-7 years old in nine regions of China in 2005. Then SPSS software was used to calculate the mean, standard deviation, the 3^rd percentile (P₃), 10^th percentile (P₁₀), 50^th percentile (P₅₀), 90^th percentile (P₉₀) and 97^th percentile (P₉₇) of the boys' age specific body mass. The curve estimation function was used to select the appropriate fitting model and to draw the body mass centile curve. The property of curves was modified in order to achieve the best effect. The template invocation function was used to overlap the curves. Results Smooth and consistent growth curve of P₃, P₁₀, P₅₀, P₉₀ and P₉₇ for children in Shanghai were constructed through data calculation, curve estimation, curve fitting, template invocation and curve overlapping by SPSS software. Conclusion SPSS software can be used for fast construction of children's growth curves, and it has the advantages of convenient operation and good practicability, which makes it worthy of popularization.
