Methods Totally 27 114 children and adolescents aged 7 to 18 years were randomly selected from Baoji city.Height and weight were measured, and body mass index(BMI) was calculated.The nutritional situation was assessed on the basis of the criteria developed by the data of the nine provinces/municipalities in 2009. Results Except for 10 to 12 years old, the height of boys was higher than that of girls in other age groups(P<0.05). The weight of boys was higher than that of girls at all age groups(P<0.05). Except for 15-and 16-years old,the BMI of boys was higher than that of girls in other age groups(P<0.05).The height of boys more than 14 years old and girls more than 12 years old were significantly higher than those of the whole country, but the national level was higher before the age of 10(P<0.05).The weight of boys more than 10 years old and girls of all ages were higher than those of the whole country(P<0.05).The BMI of boys and girls in all age groups were higher than those of the national level(P<0.05).The detection rates of stunting,underweight, wasting,overweight and obesity were 2.6%,1.5%,9.1%,13.7% and 8.5%,respectively.And the prevalence of boys were higher than those of girls(P<0.05).There were significant differences on the prevalence of stunting,underweight,wasting and obesity among different school age groups(P<0.001).
