Objectives: Investigate risk of mis‐matched pre vs. postnatal growths on childhood overweight and the urbanization effects on childhood excessive growth in China. Methods: Childhood excessive weight growth defined as upward crossing of major percentile lines of child weight growth references compared to birth weight percentile. Using conditional transition probability analysis, logistic regression and GEE models, we examined longitudinal effect of excessive weight growth on childhood overweight at age4‐5 and its association with socio‐environmental characteristics among 117,398 children repeatedly followed during 2000‐2005 in South China. Results: The 35.7% of children experienced excessive growth of weight at least once and 64.2% continuously kept excessive growth up to age 4‐5 y. Those with excessive weight growth were more likely to be overweight (BMI Z score>=1) at age 4‐5[RR= 3.83, (95%CI: 3.34‐ 4.38)]. Especially those in urban areas, having a mother with a job and higher education showed significantly higher risk of childhood excessive weight growth than their counterparts[OR=1.8 (1.5‐ 2.1); 1.2 (1.1‐ 1.2); 1.4 (1.3‐1.4)). Conclusions: 35.7% children had excessive weight growth compared to the birth size, positively associated with overweight risk and urban residence, maternal employment and education, indicating urbanization effect on child obesity in China.
