Effects of comprehensive intervention on 24 h activity behavior among obese students in vocational colleges
Objective To explore the effects of comprehensive intervention measures targeting physical activity,sedentary,sleep and other behaviors on 24 h activity behavior of obese students in vocational colleges,so as to provide a more tailored empiri-cal basis for intervening obese students in vocational colleges.Methods A quasi-experimental design using parallel controlled,randomized grouping was conducted from January to March 2023.A total of 79 first-year obese students from a vocational college in Wuxi City were selected as the intervention group(41 students)and the control group(38 students).From April to June,2023,the control group received no intervention,while the intervention group adopted an information-based and behavioral intervention ap-proach to comprehensively intervene in 24 h physical activity,sedentary,sleep and other behaviors(120 minutes each day for 8 weeks).Wherein,information-based intervention mainly used paper leaflets and social and learning software to accurately push inter-vention information,and behavioral intervention mainly concentrated 1 hour of physical exercise and multiple activity behavior re-quirements every day with the triaxial accelerometer to feedback the objective data of physical activity.Subsequently,from June to July,2023,a one-week post-test and follow-up survey were conducted respectively.Bouchard diary in physical activity,Weekly questionnaire and triaxial accelerometer were used to record the 24 h activity behavior of both groups of students.T-test and repeated measurement analysis of variance were used to compare the differences of 24 h activity component index time between two groups be-fore and after intervention and examine the changes within each group.Results Before and after intervention,there was no signifi-cant difference in the time of each component index of 24 h activity behavior in the control group.However,repeated measures anal-ysis of variance between the intervention group and the control group revealed statistically significant interaction differences in physi-cal activity,sedentary behavior,sleep and other index time were statistically significant(pre-test and post-test:F=6.45,4.66,7.21,7.88;pre-test,post-test and follow-up-test:F=5.37,5.12,5.43,5.29;P＜0.01).During the follow-up period,compared with the post-test data[(313.25±54.15,601.88±65.47,462.83±42.86,61.92±18.53)min/d],the time of each component(physical ac-tivity,sedentary behavior,sleep,other)of the 24 h activity behavior of students in the intervention group rebounded[(298.52± 60.27,613.69±68.55,442.33±45.26,85.28±20.57)min/d],but it was better than the pre-test data[(230.45±67.42,720.32± 105.63,369.78±32.31,119.29±22.17)min/d],and the difference was statistically significant(F=42.46,39.45,33.41,59.43,P＜0.01).During the intervention period,the physical activity,sedentary and sleep duration indicators of the intervention group students showed fluctuating patterns in the 4th and 5th weeks.Conclusions The comprehensive intervention on 24 h activity be-havior among obese students in vocational colleges shows significant effectiveness,but its sustainability is insufficient.Considering the characteristics of obese students in vocational colleges,personalized intervention measures should be provided to increase physi-cal activity and sleep time and reduce static activity time,in order to promote students to develop a healthy lifestyle.
