Abstract: Objective To investigate the changes of physical development and obesity of preschool children in urban areas of Qingdao over the past 12 years,in order to provide evidence for the health management of preschool children. Methods Stratified cluster sampling method was used to select 13 kindergartens in Qingdao urban area. The height,weight and nutritional status of children was measured and evaluated in the late March to late April of 2018, the overweight and obesity detection rates were calculated. Data on obesity were compared between 2018 and 2006. Results Compared with 2006,there was no significant difference on the overall height of preschool children in urban areas of Qingdao in 2018(P>0.05),and the body weight decreased except 3-year-old group(P<0.001). In 2018,the detection rates of obesity(7.5%),overweight(15.9%) and growth retardation(0.2%) in preschool children in Qingdao were all significantly lower than those in 2006(P <0.05). Conclusion Under the premise of normal height development in 2018 in Qingdao,the detection rates of obesity and overweight are lower than that in 2006,which proves that the measures from early life,based on community kindergartens and families,and the ongoing prevention and control strategy for comprehensive obesity in children are effective.
