Abstract
Objective To evaluate the growth development status of rural children aged 0~7 years,and to observe the dynamic changes in 20 years in Yizhan County.Method Health check-up data of rural children in Yizhan County from 1985 to 2005 were analyzed by using longitudinal comparison.Results Weight of 0~7-year-old children was lower than WHO standard(1997) in 2005.However,weight of 3~4-year-old children was above NCHS/WHO standard.Height of children under 3-year-old was lower than WHO standard(1995).The growth data showed an increasing trend in 0~7-year-old children as compared with the results obtained in 1985 in Yizhan.The average increases of the weight,body height,and body mass index(BMI) were 1.09kg,3.80cm,and 0.25kg/m2 respectively.Conclusion Children aged between 0 and 7 years have a positive secular change in Yizhan since 1985.
