Prevalence and time changing trends of wasting,overweight and obesity among children and adolescents aged 6-17 years in Wuhan City,2019-2022
Objective To understand the prevalence of and time changing trend in wasting,overweight and obesity amongst children and adolescents in Wuhan City from 2019 to 2022.Methods Based on the data regarding the Monitoring and Intervention Project of Common Diseases and Health Influencing Factors among Students in Wuhan City from 2019 to 2022,body mass index(BMI)was calculated by height and weight among 18,330 children and adolescents.Cochran-Armigtage trend test was used to explore the time changing trend,and x2 test was employed to compare the differences among groups.Results The detection rate of wasting decreased from 5.20％in 2019 to 3.40％in 2022,showing a decreasing trend(Z=-3.080,P＜0.05).The detection rate of obesity increased from 13.73％in 2019 to 18.07％in 2022,showing an increasing trend(Z=-4.536,P＜0.05).The total detection rates of wasting,overweight and obesity were 4.10％,17.14％and 16.36％respectively.The detection rates of wasting,overweight and obesity were all higher in male students than in female ones.The detection rates of overweight and obesity were higher in the main urban area than in the area far from the main urban area.The detection rates of wasting and overweight were found to be the highest in the group aged 15-17 years,while the detection rate of obesity was found to be the highest in the group aged 6-8 years,showing statistically significant differences in the different age groups(P＜0.05).Conclusion The prevalence of wasting among children and adolescents aged 6-17 years in Wuhan City has been alleviated.The prevalence of obesity is increasing year by year,and the situation is grim.
