Abstract:Objective We aimed to estimate the trends in physical growth of preschool children in Beijing, and to explore gender and regional disparities. Methods A total of 6406 and 6196 children aged 3-6 years were extracted from 2005 and 2014 national physical fitness surveillance surveys in Beijing. Height and weight were directly measured and growth indicators were calculated using national reference standards. The trends in the prevalence were tested by t-test, chi-square test and generalized linear models. Results Compared to 2005, the stunting and underweight prevalence of boys and girls decreased in 2014(P<0.05), while the overweight prevalence increased(P<0.05). In 2005, children in rural area had higher prevalence of stunting, underweight and wasted than those in urban area 2005(P<0.05), but the differences disappeared in 2014. The prevalence of overweight for children in urban area was 4.5% higher than that for children in rural area in 2005(P<0.01), while, in 2014, the prevalence of the latter was 2.2% higher than the former(P<0.05). Interaction tests indicated that children in rural area had 1.59 times higher odds of being overweight than children in urban area in 2014 compared with 2005. Conclusion The stunting, underweight and wasted prevalence of preschool children significantly decreased in Beijing between 2005 to 2014. There have been physical growth disparities between regions, with children in rural area bearing higher overweight risks than those in urban area. Effective interventions are in dire need to promote early development.
