Previous research has demonstrated a virtual absence of vitamin A deficiency and adequacy of vitamin A intake through consumption of liver in preschool children of a community in the Northern Cape province of South Africa where sheep farming is common, and liver, an exceptionally rich source of vitamin A, is frequently eaten. Only 60-75 g of liver per month is needed to meet the vitamin A requirement of preschool children. Because this may have implications for routine vitamin A supplementation, and because liver consumption for the rest of the province is unknown, the study aim was to establish the prevalence and frequency of liver intake in a provincial-wide survey.

Serum retinol was assessed in mothers and newborns from an impoverished South African community where liver is frequently eaten and vitamin A deficiency known to be absent. Paired cord and maternal blood (n = 201) were collected after delivery and analysed for serum retinol and C-reactive protein (CRP). Liver intake during pregnancy and intention to breastfeed were also assessed.

Objectives: This cross-sectional study examined the nutritional factors associated with the high levels of stunting in 2- to 5-y-old children in an impoverished South African setting where liver is frequently eaten and vitamin A deficiency known to be absent.

Methods: Children's dietary intake was assessed by a single 24-h recall. Heights and weights were measured and information was obtained on breast-feeding history, the child's habitual milk intake, as well as substance use by the mother during pregnancy (n = 150).

Objective: The aim of this study was to assess the vitamin A and anthropometric status of South African preschool children from four areas with known distinct eating patterns.

Methods: Serum retinol, anthropometric indicators, and dietary intake were determined for randomly selected preschool children from two rural areas, i.e.

Article Synopsis
  • Iodine deficiency during pregnancy negatively affects fetal growth, but its impact on growth after birth is less understood.
  • The study aimed to see if improving iodine levels in children would enhance their growth and explored the involvement of specific growth factors (IGF-I and IGFBP-3).
  • Three controlled studies showed that iodine repletion significantly boosted growth and hormone levels in iodine-deficient children from Morocco, Albania, and South Africa, with notable improvements in height and weight.
