目的:探讨喂养指数评分在评价广东江门地区婴幼儿主要微量元素营养状况的应用效果。方法:以中国疾病预防控制中心营养与食品安全所提出的喂养指数评分体系为依据,评价广东江门地区522例6~12月龄婴幼儿的喂养指数评分,并分析喂养指数与主要微量元素营养状况的关系。结果:研究婴儿群体的平均喂养指数为9.52±1.24分,其中6~8月龄组为9.45±1.41分,8~12月龄组为9.57±1.24分。6~8月龄组与8~12月龄组喂养指数合格组婴儿的血清锌、钙和铁的水平均显著高于相应的喂养指数不合格组(P<0.05),而血清铜和血清镁水平则无显著差异(P>0.05);并且合格组婴儿低铁、低锌以及低钙血症发病率都显著低于不合格组婴儿(P<0.05),而低镁和低铜血症发生率两组儿童无显著差异(P>0.05)。结论:婴幼儿喂养指数评分标准可以较为准确的反映江门地区婴儿主要微量元素营养状况,为早期预防和诊断提供一个较为可靠的评估指标。
Objective: To evaluate the effect of feeding index score on the nutritional status of major trace elements in infants and young children in Jiangmen, Guangdong Province. Methods: Based on the feeding index scoring system proposed by China Center for Disease Control and Prevention for feeding and food safety, we evaluated the feeding index scores of 522 infants aged 6 ~ 12 months in Jiangmen, Guangdong Province, and analyzed the relationship between feeding index and the nutritional status of major trace elements Relationship. Results: The mean feeding index of infants was 9.52 ± 1.24, with 9.45 ± 1.41 in 6-8 months and 9.57 ± 1.24 in 8-12 months. The levels of serum zinc, calcium and iron in 6-8 months old and 8-12 months old infants with feeding index were significantly higher than those of the corresponding feeding index unqualified group (P <0.05), while serum copper and serum magnesium (P> 0.05). The incidences of low iron, low zinc and hypocalcemia in eligible group were significantly lower than those in unqualified group (P <0.05), while low magnesium and low copper occurred Rate of two groups of children no significant difference (P> 0.05). Conclusion: The score of infant feeding index can reflect the nutritional status of the main trace elements in infants in Jiangmen area more accurately, and provide a more reliable evaluation index for early prevention and diagnosis.
