【目的】了解榆林地区儿童体内微、常量元素状况及饮食行为的关系,为合理制定不同发育阶段儿童膳食方案提供参考。【方法】对7 396例1～7岁儿童进行了微、常量元素的测定,并与饮食行为之间进行比较。【结果】榆林区儿童存在不同程度的常、微量元素缺乏情况,其中锌、铁、钙缺乏情况最为严重,缺锌居第1位(49.80%),缺铁居第2位(41.85%),其次为缺钙(29.91%)。各年龄组常、微量元素锌、铁、钙比较差异具有统计学意义(P<0.05)。大部分儿童普遍存在不良饮食行为习惯,儿童血锌与血铁明显高于饮食行为习惯差组儿童,差异有统计学意义(P<0.05)。【结论】榆林地区1～7岁儿童部分常、微量元素缺乏较普遍,并与饮食行为有一定的关系,应加大宣传力度,合理调整饮食结构及纠正不良饮食行为。
【Objective】 To understand the relationship between micro and macroelements and dietary behaviors of children in Yulin area and to provide reference for the reasonable formulation of dietary plans for children in different developmental stages. 【Method】 A total of 7 396 children aged 1 to 7 years were tested for micro and macroelements and compared with dietary behaviors. 【Results】 The results showed that the children of Yulin had different levels of regular and trace element deficiencies. Among them, zinc, iron and calcium deficiency were the most serious, the first place with zinc deficiency (49.80%), the second place with iron deficiency (41.85%), Followed by calcium deficiency (29.91%). Normal age, trace elements zinc, iron, calcium difference was statistically significant (P <0.05). Most children generally had bad eating behaviors, and children’s blood zinc and blood iron were significantly higher than children with poor eating habits, the difference was statistically significant (P <0.05). 【Conclusion】 Some of the common and trace element deficiencies in children aged 1 ~ 7 years in Yulin area are relatively common and have a certain relationship with dietary behaviors. Publicity should be intensified to rationally adjust diet structure and correct bad dietary behaviors.
