Objective To examine the weight control behaviors among the first grade high school students in Lanzhou,and to further examine their association with real and perceived weight status,in order to provide reference for scientific prevention and intervention. Methods In September 2018,1 038 first year high school students filled in the Weight Control Behavior Scale for Youth and Adolescents and answered questions regarding their perceptual weight status. Finally 1 026 valid response were collected.Total scores and adoption rates of healthy and unhealthy weight control behaviors were calculated. Results Among 1 026 high school students,364(76.15%) girls and 387(70.63%) boys adopted weight control behaviors. The most frequently adopted healthy weight control behaviors were "doing exercise" [boys 416(75.91%),girls 318(66.53%)] and "eating more fruits and vegetables" [boys 412(75.18%),girls 395(83.51%)]. While the two most frequently adopted unhealthy weight control behaviors were "skipping meals" [boys 93(16.97%),girls 82 (17.15%)] and "eating no meat"[boys 37(6.75%),girls 79(16.53%)]. More boys (21.63%) were actually overweight than girls (9.79%). However,52.83% of girls perceived overweight. Moreover,students who perceived overweight were more likely to adopted unhealthy weight control behaviors (χ2=38.94,P<0.01). Conclusions Weight control behaviors are common among first year high school students,which are associated with their weight perceptual bias. Therefore,psychological prevention and interventions are needed.
