Special Issue Information

Dear Colleagues,

Children and women of reproductive age are at greater risk of micronutrient deficiency. Globally, an estimated two-thirds of non-pregnant women of reproductive age and over half of children under five years old suffer from at least one form of micronutrient deficiency. Furthermore, the magnitude of the problem is much greater in low- and middle-income countries where multiple micronutrient deficiencies often occur concurrently because of a poor-quality diet. Among the micronutrients, the most common deficiencies include iron, vitamin A, iodine, folate, and zinc. Micronutrient deficiencies are a major contributing factor to both short- and long-term poor health and suboptimal development outcomes, especially among women and children.  

While micronutrient deficiencies could be prevented through a healthy diet containing diverse foods, as well as through food fortification and supplementation with micronutrients, the burden of micronutrient deficiency exists as a major public health problem worldwide. 

The present Special Issue aims to bring together the latest research on the potential health and developmental impacts of micronutrient supplementation among women of reproductive age including pregnant women, adolescent girls, and children. Submissions of original papers, reviews, meta-analyses, and commentaries on the aforementioned issue are welcome.

Benefits of Publishing in a Special Issue

  • Ease of navigation: Grouping papers by topic helps scholars navigate broad scope journals more efficiently.
  • Greater discoverability: Special Issues support the reach and impact of scientific research. Articles in Special Issues are more discoverable and cited more frequently.
  • Expansion of research network: Special Issues facilitate connections among authors, fostering scientific collaborations.
  • External promotion: Articles in Special Issues are often promoted through the journal's social media, increasing their visibility.
  • e-Book format: Special Issues with more than 10 articles can be published as dedicated e-books, ensuring wide and rapid dissemination.

Background/Objectives: Adequate folate intake is required in preterm infants for rapid growth and development, but there is little evidence to back recommendations. We aimed to assess folate status in preterm infants at discharge and in early infancy, according to exposure to folate sources, particularly in those exclusively/predominantly breastfed. Methods: A prospective, multicenter, observational cohort study was conducted in the UK, involving 45 preterm infants <33 weeks’ gestational age (GA) exclusively/predominantly fed human milk when approaching NICU (Neonatal Intensive Care Unit) discharge. Serum folate levels were measured near NICU discharge (T1) and at 2–3 months corrected age (T2). Folate status was categorized per WHO (World Health Organization) guidelines: deficiency (<6.8 nmol/L), possible deficiency (6.8–13.4 nmol/L), normal (13.5–45.3 nmol/L), and elevated (>45.3 nmol/L). Nutritional information on feed and supplements was collected from hospital notes and maternal interviews. Results: Thirty-two infants (71%) received parenteral nutrition. Twelve infants (32%) remained exclusively breastfed at T2. No infant from the whole cohort had a serum folate concentration <13.5 nmol/L at either time point. A proportion of infants had serum folate concentrations >45.3 nmol/L: 14/45 (31%) at T1, 19/37 (42%) at T2, and 7/37 (16%) at both time points. Elevated concentrations were seen particularly in infants who received folic acid supplements or nutrition containing folic acid, such as parenteral nutrition and breastmilk fortifiers. Conclusions: Folate deficiency was not observed in this cohort; folate concentrations were high and in line with those observed in healthy term infants. Further research is needed to assess the high folate concentrations in premature babies and whether they may have any adverse clinical impact. Full article

In Bangladesh, groundwater, the principal source of drinking water, contains predominantly high levels of iron. Drinking groundwater is associated with good iron status in populations. Against this backdrop, iron supplementation is often associated with side effects, which reduces its intake compliance. However, the level of iron in groundwater is not consistent, and low levels exist in many areas of the country. In the present study, we examined the role of groundwater with a low concentration of iron in the prevention of anemia in Bangladeshi children. In 2018, a cross-sectional study was conducted in Bangladesh among children aged 2–5 years (n = 122) who drank groundwater containing a low level of iron (0–<2 mg/L). The combined intake of iron was calculated from the key sources—diet, groundwater, and the simulated intake of MNPs. The intakes of iron were compared against the standard reference intake. The children’s hemoglobin levels were measured using a photometer. The combined intake of iron from diet, groundwater with low levels of iron, and the simulated consumption of low-iron MNP in children was 5.8 ± 2.0 and 6.9 ± 2.5 mg/day, comprising 193% and 169% of the Estimated Average Requirements in the 2–3-year-old and 4–5-year-old subgroups, respectively. The combined intake of bioavailable iron from dietary and low-iron groundwater was 0.42 ± 0.023 and 0.22 ± 0.019 mg/day in children exposed to groundwater concentrations of 0.8–<2.0 mg/L and 0.0–<0.8 mg/L, respectively (p < 0.001). The mean concentration of hemoglobin in the respective groups was 12.17 ± 0.94 g/dL and 11.91 ± 0.91 g/dL (p = 0.30). The combined intake of iron from diet and the low-iron groundwater was associated with maintenance of hemoglobin concentration at the non-anemic level in > 90% of the children. The findings highlight the protective influence of the low concentration of iron in the drinking groundwater against childhood anemia in Bangladesh. Full article
