Compared to control group:（1）P<0.01

The changes in BAZ for the intervention and control groups are shown in Table 2 and Figure 1.The mean BAZ of the control group increased from-0.50to-0.30 while it increased from-0.56 to 0.04 in the intervention group.The increase in BAZ in the intervention group was significantly greater than that in the control group（P<0.01）.Based on the results from the multiple linear regression model，after adjusting for age，gender，ethnicity，baseline BAZ，parents’education，parents’occupation，and parents’BMI，the effect of 2 years of nutrition education intervention on the change in BAZ is shown in Table 3（standardized coefficient:0.322；P=0.000）.
