Abstract: Objective: To observe the health condition and tendency of gathered living children aged from 0 to 6 years in Hefei,and to explore intervention measures. Methods: In this study 240 771 children were enrolled; their health development tendency was analyzed by comparing the height,weight,malnutrition,obesity,anemia,vision acuity and dental caries during 2005 to 2009. Results: The number of children above the second Quartile of height and weight increased(P < 0.01); the incidence of malnutrition,anemia and poor sight decreased yearly(P < 0.01),but the prevalence of obesity increased(P < 0.01). With the age advancing,the incidence of dental caries increased(P < 0.01). Conclusions: Gathered living children aged from 0 to 6 years in Hefei are in good health. The prevalence of nutrition is decreased while obesity increased; the children' s visual sight and anemia couldn' t be neglected. The prevention and intervention of obesity and ophthalmology diseases are pivotal to nurseries and kindergartens.
