摘　　要：目的:研究增加饮奶量对学龄儿童体格发育及体质指数的影响,为学龄儿童精准营养改善工作提供科学研究依据。方法:采用人群干预实验研究方法。研究期间,为干预组在校期间每日提供200 mL牛奶,并配合营养相关健康教育。在研究结束时,使用t检验和卡方检验分别比较干预组和对照组在体格发育、体质指数以及营养不良发生率的变化差异。结果:从总体上看,与基线相比,干预组对照组的身高均值的变化分别为0.08、0.06 m,干预组和对照组的体重均值的变化分别为4.80、3.58 kg,干预组和对照组的消瘦率分别下降4.8%和1.4%,超重和肥胖率干预组与对照变化相当且均呈下降趋势。结论:增加饮奶量在促进学龄儿童体格发育和改善体质指数的同时,不会造成超重肥胖的发生。【Objective】To detect the effects of increased milk consumption on physical development and BMI in school children,and provide the scientific evidences for precise intervention of nutrition improving in school children.【Method】Intervention experimental study was adopted.During the study period,the subjects in intervention group were provided 200 mL milk in every school day,meanwhile,nutrition-related health education was conducted.T test and chi-square test were used to detect the differences of physical development,BMI and nutritional status between intervention group and control group at the end of the study.【Result】On the whole,comparing with the data of baseline,the mean height growths in intervention group and control group were 0.08 m and 0.06 m,respectively.The mean weight growths in intervention group and control group were 4.80 kg and 3.58 kg,respectively.The ratio changes of wasting in intervention group and control group were-4.8%and-1.4%,respectively.The ratio changes of overweight and obesity were all similar in both groups and presented declining trends.【Conclusion】Increased milk consumption could improve the physical development and BMI amelioration,and could not cause the occurrence of overweight and obesity.
