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.
Abstract
[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.
