Association between the 24-hour movement behaviors and executive function in preschoolers
Objective To explore the characteristics of 24-hour movement in preschoolers and its relationship with executive function.Methods The study subjects consisted of 555 preschoolers in Zhuhai City.An objective measurement approach was employed,physical activity level was assessed by utilizing ac-celerometers and executive function was evaluated by computerized behavioral tests.The characteristics of 24-hour movement in children were described.Data were analyzed using SPSS 26.0 software,independent samples t-test was used to compare differences in 24-hour activity behaviors across genders,and multivariate linear regression was used to explore the effect of preschoolers'achievement of activity behaviors on executive functioning.Results According to the physical activity guideline for Chinese preschoolers aged 3-6 years recommendations for children's daily moderate to vigorous-intensity physical activity,sedentary screen time,and sleep duration,among the study participants,the compliance rate of moderate to vigorous-intensity physi-cal activity(≥60 min/d)was 33.9％(188/555),sedentary screen time(≤1 h/d)was 43.4％(241/555),and sleep duration(10-13 h/d)was 83.4％(463/555).Only 13.3％(74/555)of the participants met the recommended guidelines for all three behaviors.The correct score of the working memory test was(60.6±20.3)and the reaction time of the inhibitory control test was(695.1±135.8)ms.In male pre-schoolers,moderate to vigorous-intensity physical activity(≥60 min/d)positively predicted working memory(β=0.121,P=0.037),while sedentary screen time(≤1 h/d)negatively predicted inhibitory control(β=-0.122,P=0.036).Conclusions The daily compliance rate of moderate to vigorous-intensity physical ac-tivity and sedentary screen time is low among preschooler.The former is positively correlated with working memory in preschool boys,while the latter is negatively correlated with inhibitory control.
