Methods Three areas (Suzhou city,Hefei city,Chizhou city) in Anhui were selected.6 082 urban and rural primary school students aged from 7 to 12 years old were recruited.Body heights were measured and evaluated using the nine cities' growth standard,the prevalence of short stature was calculated. Results In addition to 11 years old girls' height was significantly higher than that of boys,the rest of the age group of the girls were behind the height of the boys during children aged from 7 to 12 years old in AnHui province.In Hefei city,height of 12 years old boys and 11~12 years old girls were significantly higher than those of Suzhou city,height of 9 and 11 years old boys were shorter than those of Suzhou city.In the rest of the age group,there were no significant differences in Hefei and Suzhou city in the same gender group.Children's heights of Hefei and Suzhou city were higher than that of Chizhou city.The total prevalence of short stature in 7~12 years old children in Anhui province was 2.83%.The prevalence of short stature in boys and girls in urban areas respectively were 2.32% and 2.13%;Those in rural area were 3.15% and 3.72%.At the same age and gender group,children's height of Chizhou city was significantly behind the other two cities,the rate was significantly higher in rural area than that in urban area.
