Abstract: Objective To understand the growth and development, and anemia among 2- to 6-year-old children registered in kindergartens in Lasa, so as to provide scientific reference for making health promotion policies. Methods Totally 1 995 children aged 2 to 6 years, who went to health examination for kindergarten entrance in 2018 in Maternal and Child Health Care Hospital of Tibet Autonomous Region, were enrolled in this study.Children's height, weight, hemoglobin and serum iron were measured. Results Among 1 995 children, 1 016(50.93%) were boys.Most children were 3 years old (1 439, 72.13%), and Tibetan (1 766, 88.52%).The overall prevalence rates of underweight, stunting, wasting and anemia were 22.06%, 8.37%, 1.45% and 68.57%, respectively.The prevalence of underweight increased with age ( χ²_trend=53.42, P<0.001).The prevalence of underweight was 34.84%.Tibetan children had a lower prevalence rate of underweight than non-Tibetan children (21.18% vs 28.82%, χ²=6.89,P<0.01).The prevalence of anemia among different age groups were significantly different (χ²=33.10, P<0.001).The prevalence of anemia was highest (69.28%) among 3-year-old children.Tibetan children had a higher anemia prevalence than non-Tibetan children (71.07% vs.49.34%, χ²=49.95, P<0.001). Conclusions The overall prevalence of underweight, stunting, wasting and anemia are relatively high, and the growth and development is suboptimal.It is suggested to give targeted health education about appropriate feeding taking consideration of local Tibetan food culture.Moreover, food rich in iron or helpful to promote iron absorption should be especially encouraged.
