Objective To explore of executive function in obese adolescents,so as to provide a reference for executive function enhancement intervention in obese adolescents.Methods A convenience sample of 1 227 adolescents aged 13-18 years was se-lected from 2 secondary schools in Taiyuan City during March-April 2023.The Flanker task,N-back task and More-odd shifting task was used to compare the different subfunctions of executive function(refreshing function,shifting function,inhibiting function)of 61 obese adolescents and 70 normal-weight adolescents.Independent samples t-tests was used for between-group comparisons and Cohen's d-tests was used to calculate between-group differences in executive function between the two groups of adolescents.Re-sults Compared with the group of normal weight,time responses of the inhibitory function[(29.73±19.55)ms],the refreshing function[1-back:(1 088.75±275.76)ms,2-back:(1 285.44±355.16)ms]and the shifting function[(380.34±153.18)ms]in the obese group were significantly longer than those in the normal weight group[(14.86±20.27,888.38±286.57,1 126.20± 287.43,323.12±134.71)ms](t=4.26,4.06,1.92,2.26,P＜0.05);inhibitory function(0.91±0.09)and 1-back(0.73±0.24)were also significantly less correct than in the normal weight group(0.94±0.05,0.83±0.21)(t=-2.04,-2.04,P＜0.05).Obese adolescents showed moderate adverse effect sizes in the inhibition function(d=0.746,0.712)and the refresh function 1-back,and smaller adverse effect sizes in the refresh function 2-back and the conversion function(d=0.497,0.398).Conclusion Obese ado-lescents have significant executive function deficits,but the degree of adverse varies across sub-functions,with inhibitory function being the core deficit component of executive function in obese adolescents.
