Notes and Remarks

Remarks

  • The GDG noted that the evidence on harms (decreased neurodevelopment) was uncertain due to verylow-certainty evidence and imprecision.
  • The recommendation is conditional on shared decision-making with parents; this includes informing parents about the benefits and risks and the need for further research.
  • The GDG noted that there were limited data on the dose, timing of initiation and duration of supplementation. Based on most trials included in the evidence review, the GDG suggests a daily dose of 1–3 mg/kg per day of elemental zinc. The GDG also suggests that zinc may be initiated when enteral feeds are well established, and may be continued until the infant receives zinc from another source.
