摘要

背景/目的:本研究旨在评估韩国幼儿和学龄前儿童的锌食物来源和通常的膳食锌摄入量:从 2009-2013 年韩国国民健康与营养调查(KNHANES)数据中选取了 2,679 名 1-5 岁儿童。通过单次 24 小时回忆收集的膳食数据来评估锌的食物来源。为了估算通常的锌摄入量,利用 2009 年韩国国民健康与营养调查(KNHANES)2 天 24 小时回忆子样本数据中锌摄入量的人内方差与人际方差之比,对总样本中单次 24 小时回忆数据的分布进行了调整。评估了平时锌摄入量低于估计平均需要量(EAR)和高于可耐受摄入量上限(UL)的儿童比例:韩国儿童锌的主要来源是谷物、奶制品和肉类。所有儿童、1-2 岁儿童和 3-5 岁儿童通常的锌平均摄入量分别为 5.50、5.01 和 5.83 毫克/天。在所有参与者中,1.1% 的儿童锌摄入量低于 EAR,而 10.7% 的儿童锌摄入量超过 UL。锌摄入量超标的儿童比例在 1-2 岁年龄组为 25.6%,在 3-5 岁年龄组为 0.6%:结论:根据目前的锌摄入量测定标准,韩国幼儿摄入过量锌的风险似乎很高。今后需要对锌摄入过量对健康的影响进行监测研究,以适当指导儿童的锌摄入量。

Food sources of zinc and nutritional status with usual dietary zinc intake in Korean toddlers and preschool children.

Background/objectives: This study aimed to evaluate the food sources of zinc and the usual intake of dietary zinc among Korean toddlers and preschool children.

Subjects/methods: A total of 2,679 children aged 1-5 years was selected from the 2009-2013 Korea National Health and Nutrition Examination Survey (KNHANES) data. Dietary data collected from a single 24-h recall were used to evaluate the food sources of zinc. To estimate usual zinc intake, the distribution obtained from single 24-h recall data in the total sample was adjusted using the ratio of within-to-between-person variance in zinc intake obtained from 2-day 24-h recall sub-sample data of the 2009 KNHANES. The proportion of children with usual zinc intake below the estimated average requirement (EAR) and above the tolerable upper intake level (UL) was assessed.

Results: The main sources of zinc in Korean children were grains, dairy products, and meat. The mean usual intakes of zinc among all individuals, those aged 1-2 yrs, and those aged 3-5 yrs were 5.50, 5.01, and 5.83 mg/d, respectively. In all participants, 1.1% of the children consumed zinc below the EAR, whereas 10.7% exceeded the UL. The proportion of children with excessive zinc intake was 25.6% in the 1-2 yrs age group and 0.6% in the 3-5 yrs age group.

Conclusions: According to the current UL, the risk of excessive zinc intake appears to be high among Korean toddlers. Future studies that monitor the health effects of excessive zinc intake are needed to appropriately guide zinc intake in children.
