Objective To analyze the correlation of body image dissatisfaction and body shape parameters,and to provide the basis for guideing children and adolescents to get correct body image. Methods Students were selected using stratified cluster sampling method,and measured height,weight,waist circumference (WC),hip circumference (HC),and skinfold thichness,and surveyed body image by Ma body figural shape.The correlation of body image dissatisfaction and body shape parameters was analyzed using simple level and multiple level methods. Results Prevalence rate of body image dissatisfaction was 77.1% [23.1% students expected to be fat (EBF),54.0% students expected to thin (EBT)] and prevalence of body image distortion was 44.9%;The rate of EBF in males was higher than in females (χ²=4.989,P=0.026),however,the rate of EBT in females was higher than in males (χ²=5.970,P=0.015).In males and females,height,weight,WC,HC,skinfold thickness,body mass index (BMI),waist-height ratio (WHtR),and hip comunference-to-height ratio (HHR) were higher in EBT than body image satisfaction (P all ＜0.05); In males,all above variables were higher in body image satisfaction than EBF(P all ＜0.05; Excepting for height and WHR,others were higher in body image satisfaction than EBF In females(P all ＜0.01).Differences of above variables between EBT or EBF and body image satisfaction were higher in males than females,in middle school students than primary school students. Conclusion There are the correlations between height,weight,WC,HC,WHtR,HHR and body image,and are different between males and females or middle and priamary school students.
