Iodised salt and iodine supplements for prenatal and postnatal growth: a rapid scoping of existing systematic reviews

Iodised salt and iodine supplements for prenatal and postnatal growth: a rapid scoping of existing systematic reviews

Iodine deficiency can adversely affect child development including stunted growth. However, the effect of iodine supplementation or fortification on prenatal and postnatal growth in children (<18 years) is unclear.

The potential need for a systematic review which would contribute to the evidence base in this area was identified. To avoid duplication and inform the need for a new systematic review and its protocol, a rapid scoping review of existing systematic reviews investigating the effect of iodised salt and iodine supplements on growth and other iodine-related outcomes was undertaken.

The rapid scoping review demonstrates a gap in the evidence base with no existing, up-to-date systematic reviews on the effects of all forms of iodine supplementation/fortification in all of the relevant population groups on relevant growth and growth-related outcomes. A new systematic review examining this question will assist in addressing this gap.
