To explore the current situation and trend of growth, development and nutrition of children aged 3-6 in Zhejiang Province, To provide reference for improving growth and development level.

Under the unified organization of the National Physical Fitness Monitoring Center, the research group measured the body shape data of children aged 3 to 6 years in Zhejiang Province, and compared and analyzed the body shape data of children aged 3 to 6 years in Zhejiang Province based on 2014 and 2020.

In terms of growth and development, the children aged 3-6 years in Zhejiang Province were in good condition in 2020, and all indicators of boys were higher than those of girls (P<0.05), with a small urban-rural difference. Compared with 2014, height (F_man=4.08, P<0.05; F_women=210.82, P<0.01), weight (F_man=18.33, P<0.01; F_women=10.26, P<0.01) and BMI (F_man=25.41, P<0.01; F_women=6.19, P<0.05) increased in 2020 (P<0.05). In terms of nutritional status, the prevalence rates of overweight and obesity were 13.0% and 8.4% among children aged 3-6 years in Zhejiang province in 2020, and the prevalence rates of overweight and obesity in boys were higher than those in girls (P<0.05). The rates of overweight and obesity in rural boys were 1.6% and 2.6% higher than those in urban children, and the rates in rural girls were 2.4% and 1.2% higher than those in urban children. From 2014 to 2020, the overall prevalence rates of overweight and obesity in young children showed an upward trend. The overweight and obesity rates in boys increased by 3.1% and 2.0%, respectively (P< 0.05), and girls increased by 0.9% and 0.4%, respectively.

In Zhejiang Province, children’s growth and development level increase steadily, but the risk of overweight and obesity is on the rise, especially in rural areas. Effective measures should be taken to curb the growing trend of overweight and obesity.
