摘要 目的 探讨趣味性有氧运动结合健康膳食对小学生肥胖的干预效果及体脂代谢的影响。方法 2015—2019年通过夏令营活动,招募辖区内4所小学的200名小学生肥胖儿童,进行趣味性有氧运动结合健康膳食干预,观察干预效果及脂代谢指标。结果 4周干预后,儿童体重、体质量指数(BMI)、体脂含量、体脂率、甘油三酯(TG)、总胆固醇(TC)、低密度脂蛋白(LDL-C)水平均低于干预前,差异有统计学意义(P<0.05),高密度脂蛋白(HDL-C)水平高于干预前,差异有统计学意义(P<0.05)。结论 趣味性有氧运动结合健康膳食可有效减轻小学生肥胖儿童的体重,促进体脂代谢,调节血脂水平。

Abstract Objective To explore the preventive effect of fun aerobic exercise combined with healthy diet on obesity in primary school students and the influence on body fat metabolism.Methods A sample of 200 children with obesity among primary school pupils from 4 primary schools in the jurisdiction from 2015 to 2019, all children were given fun aerobic exercise combined with a healthy diet.Analyze the effect of its intervention.Results After 4 weeks of intervention,the childrens weight,BMI,body fat content,body fat percentage,TG,TC and LDL-C levels were lower than before the intervention,the difference was statistically significant (P<0.05).The level of HDL-C was higher than before the intervention,the difference was statistically significant (P<0.05).Conclusion Fun aerobic exercise combined with healthy diet can effectively reduce the weight of obese children in primary school students, promote body fat metabolism, and regulate blood lipid levels.

隨着我国经济水平不断提高,人们生活习惯、饮食结构均发生较大改变,儿童青少年肥胖发生率逐年上升[1]。有研究表示,儿童青少年时期肥胖症可导致其活动能力降低,对呼吸、心血管等功能造成严重影响,还会对其成年后健康状况造成一定影响,为成年人糖尿病、高血压等心血管疾病的危险因素[2-3]。故采取合理的措施对小学生肥胖积极干预有重要临床意义。目前临床常用的减肥方法包括有氧运动、饮食疗法、药物治疗、手术干预等,其中有氧运动及饮食疗法无创无副作用,容易被接受,在小学生肥胖中具有较高适用性[4]。本研究将趣味性有氧运动结合健康膳食用于小学生肥胖干预中,旨在观察其对肥胖的预防作用及对体脂代谢的影响。
