摘要

摘要: 目的探讨4周封闭训练营的全天体力活动对代谢异常型肥胖(MUO)青少年身体成分、心血管代谢风险的改善作用，为不同代谢状态的肥胖青少年健康促进提供证据支撑。方法于2019年7—8月招募深圳某封闭训练营10~17岁肥胖青少年58名，测量受试者入营前的身体成分、血压、血脂4项和空腹血糖等指标，分为MUO组(31名)和代谢健康型肥胖(MHO)组(27名)。采用Actigraph w-GT3x BT三轴运动加速度计记录两组4周在封闭训练营中9：00—19：00的全天体力活动情况。结营后比较两组干预前后上述指标的差异及组内的变化。结果 51.6%的MUO青少年过渡为MHO青少年；体重、体质量指数(BMI)-Z评分、体脂肪量、收缩压(SBP)、三酰甘油(TG)、高密度脂蛋白胆固醇(HDL-C)和空腹血糖(FPG)的时间与组别交互作用有统计学意义(F值分别为11.25，11.25，11.04，4.89，16.75，5.92，5.57，P值均＜0.05)。组别的主效应显示，入营前MUO组的BMI-Z评分、SBP、TG和FPG高于MHO组，HDL-C低于MHO组(F值分别为5.60，6.62，20.21，10.17，31.04，P值均＜0.05)；时间的主效应显示，两组的体重、BMI-Z评分、体脂肪量、SBP、TG均下降(P值均＜0.05)，HDL-C仅在MUO组中上升(P＜0.01)，两组的FPG干预前后差异无统计学意义(P＞0.05)。体脂率、DBP、TC和LDL-C的交互作用无统计学意义(P值均＞0.05)，组别的主效应无统计学意义(P值均＞0.05)，时间的主效应有统计学意义(P值均＜0.01)。结论以封闭训练营形式增加的体力活动可以帮助MUO青少年减脂；MUO青少年在日常生活中应增加体力活动量，以降低发生心血管代谢疾病的风险。

Abstract: Objective To explore the effect of all-day physical activity in a 4-week closed training camp on the improvement of body composition and cardiovascular metabolic risk in metabolic unhealthy obese adolescents (MUO), so as to provide stronger evidence for the health promotion of obese adolescents with different metabolic states. Methods From July to August 2019, 58 obese adolescents aged 10-17 years from a closed training camp in Shenzhen were recruited and their body composition, blood pressure, lipid profile, and fasting blood glucose before admission were measured. They were divided into MUO group(n=31) and metabolic healthy obese (MHO) group(n=27). Using an Actigraphw GT3xBT triaxial accelerometer, the physical activity of the two groups during the whole day from 9:00 to 19:00 in a closed training camp for four weeks was recorded. After the conclusion of the camp, the above indicators were detected to compare the differences between the two groups before and after the intervention and the changes within the group. Results A total of 51.6% of MUO adolescents transitioned to MHO adolescents; Body weight, BMI-Z score, body fat mass, SBP, TG, HDL-C, and FPG had time×group significant interactions(F=11.25, 11.25, 11.04, 4.89, 16.75, 5.92, 5.57, P < 0.05). The main effect of the group showed that before entering the camp, the BMI-Z score, SBP, TG, and FPG in the MUO group were higher than those in the MHO group, while the HDL-C was lower than those in the MHO group(F=5.60, 6.62, 20.21, 10.17, 31.04, P < 0.05). The main effect of time showed that the body weight, BMI-Z score, body fat mass, SBP, and TG of both groups decreased significantly(P < 0.05), and HDL-C only showed a significant increase in the MUO group(P < 0.01). There was no significant change in FPG in both groups before and after intervention(P>0.05). The time×group interactions of body fat ratio, DBP, TC, and LDL-C was not significant(P>0.05), and the main effect of the group was not significant(P>0.05), the main effect of time was significant(P < 0.01). Conclusion Increased physical activity in the form of closed training camps can help MUO adolescents reduce fat, MUO adolescents should increase physical activity in their daily life to reduce the risk of cardiovascular metabolic diseases.
