The overall prevalence of overweight was 4.18%, with boy's higher than girl's (χ² = 4.343 6, P = 0.037 1) and the highest rate of overweight (5.80%) was seen in the 3-year-old group. The overall prevalence of obesity was 1.21% , with majority as mild (0.78%). There was no significant difference between boys and girls (χ² = 0.389 0, P = 0.532 8). The 6 to 7 year old group had the highest rate of obesity (1.42%). In the ten provinces, the prevalence rates of overweight were 1.38%-7.62% and the obesity were 0.57%-3.08% .
