摘　　要：目的:分析肥胖初中男生体力活动与静息能耗之间的关系,旨在为制订减肥干预措施提供理论依据。方法:采用分层随机抽样法招募初中男生,其中肥胖者为300名,体重正常者为310名。使用加速度计和自制调查问卷联合采集参与者连续7天的体力活动和能量消耗数据。采用相关性分析和多元线性回归探讨体力活动与静息能耗的关联性。同时,采用Logistic回归探讨体力活动、能量消耗与肥胖之间的关联性。结果:肥胖男生的体力活动与平均能耗均低于体重正常的男生(P<0.05)。静息能耗与肥胖呈正相关(OR=1.02,95%CI=[1.01,1.04])。久坐行为(SB)与低强度体力活动(LPA)会显著提高静息能耗(P<0.05)。当SB与LPA等时替代为每天30分钟的中等强度体力活动(MPA)或每天30分钟的高强度体力活动(VPA)时,静息能耗显著提高(P<0.05)。结论:有效减少久坐行为与低强度体力活动,增加高强度与中等强度体力活动,对于控制青少年肥胖至关重要。Objective:To analyze the quantitative relationship between physical activity and rest energy consumption of obese middle school boys,and provide theoretical basis for formulating intervention measures for weight loss.Methods:A stratified random sample of 300 obese middle school boys and 310 normal weight boys were recruited separately,and 7 d data on physical activity and energy consumption were collected using a joint accelerometer and a home-made questionnaire.Correlation analysis and multiple linear regression were used to explore the association between physical activity and rest energy consumption.Logistic regression was used to explore the association between physical activity,energy consumption and obesity.Results:The physical activity and average energy consumption of obese middle school boys were lower than those of normal weight middle school boys(P<0.05);Rest energy consumption is positively correlated with obesity(OR=1.02,95%CI=[1.01,1.04]);Sedentary behavior(SB)and lowintensity physical activity(LPA)significantly increased rest energy consumption(P<0.05);SB and LPA can significantly increase rest energy consumption(P<0.05)by substituting 30 minutes of moderate intensity physical activity(MPA)and 30 minutes of high-intensity physical activity(VPA)at the same time.Conclusion:Effective reduce SB and LPA and increase VPA and MPA is crucial for obesity control in adolescents.
