Abstract

BACKGROUND: Essential micronutrients are important for maintenance of life. Deficiency of micronutrients is more likely to be encountered in children, and women studies are required to investigate the status of micronutrients in children and women. This study aimed to longitudinally evaluate changes in zinc, copper, and iron levels in breastfed infants and their mothers during the first year of life. METHODS: Serum and hair samples were obtained from 35 healthy breastfed infants (51% males, 49% females) and their mothers 2, 6, and 12 months after delivery. All of the samples were assessed using an atomic absorption spectrophotometer. Serum iron levels were determined by a Roche/Hitachi/Modular analyzer. Statistical analyses were performed using SPSS-PC (Version 21.00) software. RESULTS: Hair zinc (p < 0.05) and serum iron (p < 0.001) levels of infants were significantly decreased towards the end of the first year. Infants' serum copper levels were increased towards the end of the first year. Maternal serum and hair copper levels and serum iron levels were significantly decreased towards the end of the first year. There were no significant correlations between dietary zinc, copper, iron intake, and trace element levels of infants and their mothers. CONCLUSIONS: Infants' hair zinc levels, maternal and infants' hair copper levels, and infants' and maternal serum iron levels declined towards the end of the first year. Infants need more zinc after 6 months of age. Infants' and mothers' daily iron intake was less than the recommended intake.

Each is checked against this paper’s own text: does it say what the citing paper says it does?

  • Micronutrient deficiencies are prevalent in infants and preschool children in developing and low- to middle-income countries, and this age group is at the highest risk of multiple micronutrient deficiencies.

    “Nevertheless, micronutrient deficiencies are prevalent in infants and preschool children in developing and low- to middle-income countries (e.g., [17,79,80,81,82]), and this age group is at the highest risk of multiple micronutrient deficiencies [83].”

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
