远程运动支持在肥胖青少年减重和维持中的应用效果观察

Effects of remote exercise support on weight loss and maintenance in obese adolescents

目的观察远程运动支持对肥胖青少年减重和维持的效果。方法采用便利抽样法,选取2018年1—12月于北大医疗潞安医院内分泌代谢科门诊就诊的118例单纯肥胖青少年患者,采用随机数字表法分为对照组和试验组,各59例。对照组接受共6个月的常规门诊随访干预,试验组同样接受6个月的门诊干预,分为干预期3个月与维持期3个月,干预期3个月基于互联网,以便携式可穿戴设备设计运动方案,结合其配套手机APP监测系统进行远程运动支持;维持期3个月采用与对照组相同的干预方式。研究共持续6个月,比较不同干预时间两组的体重变化及维持状况。结果两组在干预期(前3个月)的体重呈下降趋势,且试验组体重均低于对照组,差异有统计学意义(P<0.05);从维持期(后3个月)开始,两组体重均出现反弹,但试验组患者体重始终低于对照组,差异有统计学意义(P<0.01)。至干预期(前3个月)结束时,两组减重幅度>5%的达标率比较,差异无统计学意义(P>0.05);而试验组减重幅度>10%及减重幅度>15%的达标率高于对照组,差异有统计学意义(P<0.01)。维持期(后3个月),试验组减重幅度>5%、减重幅度>10%、减重幅度>15%的达标率均高于对照组,差异有统计学意义(P<0.01)。结论远程运动支持可以帮助肥胖青少年进一步减轻体重,并能延缓体重反弹。

Objective To observe the effect of remote exercise support on weight loss and maintenance in obese adolescents.Methods From January 2018 to December 2018,a total of 118 adolescents with simple obesity who were treated in the Outpatient Department of Endocrinology and Metabolism in PKU Care Lu'an hospital were selected by the convenient sampling method.They were divided into the control group and the experimental group by the random number table method,with 59 cases in each group.The control group received a routine outpatient follow-up intervention for 6 months and the experimental group also received a 6-month outpatient intervention.The outpatient intervention included 3 months of intervention and 3 months of maintenance.During 3 months of intervention,the mobile wearable device was used to design the exercise scheme based on the internet,and the combination of the scheme and the supporting mobile APP monitoring system was used for remote exercise support.During the maintenance period of 3 months,the same intervention method as the control group was adopted.The study lasted for 6 months.The weight change and maintenance status were compared between the two groups at different intervention times.Results In the intervention period(the first 3 months),the weight showed a trend of weight loss in two groups,and the weight in the experimental group were lower than those in the control group.The differences were statistically significant(P<0.05).From the maintenance period(the last 3 months),the weight of both groups rebounded,but the weight of patients in the experimental group were always lower than those of the control group,and the differences were statistically significant(P<0.01).By the end of the intervention period(the first 3 months),there was no statistically significant difference in the standard-reaching rate of weight loss>5%between the two groups(P>0.05).But the standard-reaching rates of weight loss>10%and weight loss>15%in the experimental group were higher than those in the control group,and the differences were statistically significant(P<0.01).During the maintenance period(the last 3 months),the standard-reaching rates of weight loss>5%,weight loss>10%and weight loss>15%in the experimental group were all higher than those in the control group,and the differences were statistically significant(P<0.01).Conclusions Remote exercise support can help obese adolescents further lose weight and delay body weight rebound.
