摘要
目的了解吉林省吉林市9～12岁朝鲜族和汉族男生营养摄入状况。方法采用随机分层整群的方法,使用膳食记录问卷对小学4、5、6年级367名男生进行3d膳食调查。结果朝鲜族和汉族男生平均每日能量摄入量分别为7.4和7.5 MJ,达营养素推荐摄入量(RNI)的77.8%和81.0%;朝鲜族男生平均每日碳水化合物、蛋白质、脂肪摄入量分别为298.0、61.5、40.6g;汉族男生分别为290.3、67.0、47.4 g;朝鲜族和汉族男生微量营养素钙、锌、维生素A、核黄素平均每日摄入量均低于RNI或适宜摄入量标准(44.8%～67.6%);朝鲜族和汉族男生营养充足比<0.7的营养素均为钙、锌、维生素A、核黄素和维生素C;汉族男生硫胺素(F=9.05,P=0.003)、烟酸(F=4.97,P=0.026)和维生素C(F=5.59,P=0.019)的营养充足比分别为(0.80±0.20)、(0.91±0.15)、(0.65±0.29),均明显高于朝鲜族男生(0.72±0.20)、(0.86±0.17)、(0.56±0.31),差异均有统计学意义。结论吉林市9～12岁朝鲜族和汉族男生均存在部分微量营养素摄入不足现象,应采取合理的综合干预措施,有效改善其膳食营养状况。
Objective To evaluate the nutrient intakes in a sample of 367 boys aged 9-12 years Korean-Chinese and Han nationality living in Jilin city. Methods Dietary nutrient intakes were assessed with 3-day dietary records under the help of teachers and parents. Results The mean daily energy intakes were 7.4MJ for Korean-Chinese and 7.5MJ for Han nationality boys,accounting for 77.8% and 81.0% of recommended nutrient intake（RNI）,respectively.The mean daily intakes of carbohydrates,protein,and fat were 298.0g,61.5g,and 40.6g for Korean-Chinese boys and 290.3g,67.0g,and 47.4g for Han nationality boys.The mean daily intakes of calcium,zinc,vitamin A,riboflavin,and vitamin C were below the RNI or adequate intake（AI） levels（44.8%-67.6%） in both ethnic boys.The mean intakes of fat,protein,thiamin,vitamin C,and niacin were significantly higher in Han nationality boys than in Korean-Chinese boys（P0.05）. Conclusion There are deficient micro-nutrient intakes in Korean-Chinese and Han boys aged 9-12 years in Jinlin city.The comprehensive measures should be taken in order to improve nutritional status of the children.
