Growth monitoring of primary and secondary students in Tongnan Dis-trict,Chongqing,during 2020-2022
Objective This study explored trends in growth and development,and health status,among primary and middle school students in Tongnan District,Chongqing,China,to provide evidence-based data for formulating targeted health intervention measures.Methods Monitoring data for primary and middle school students in Tongnan,collected from 2020 to 2022,included height,weight,and vital capacity of students of different genders and years,as well as detection rates of common diseases.Results The height and weight of boys and girls intersected at around the age of 13 years,whereas boys had greater height and weight than girls after the age of 13 years(height t-value,35.70,55.14,42.22,P＜0.01;weight t-value,12.34,14.27,18.67,P＜0.01).The difference in lung capacity between boys and girls increased from the age of 12 years(t-val-ue.27.54,29.79,34.71,P＜0.01).After the age of 14 years,the lung capacity growth rate decreased in boys and girls.Over a 3-year period,both boys and girls showed slight increases in height and weight,but a decrease in lung capacity.The preva-lence of overweight and obesity was higher in boys than girls(x2 for overweight,161.43,228.03,249.63,P＜0.01;x2 for obesi-ty,140.59,203.72,195.56,P＜0.01).The incidence of visual impairment also increased with years(boys,increase from 33.80％to 41.96％;girls,increase from 38.90％to 47.05％),and a rapid increase was observed before the age of 13 years.However,the rate of increase in visual impairment slowed during the middle school stage.The prevalence of dental caries de-creased with age and was significantly higher during primary school than middle school.Conclusions Primary and second-ary school students in Tongnan District,Chongqing,are in good physical health.Poor eyesight,overweight and obesity,and dental caries are common diseases in the area.Intervention measures for students in Tongnan should focus on myopia,over-weight,obesity,and dental caries,to further improve schoolchildren's health.
