Abstract:
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 selected 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.
Results: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 adolescents 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.
