Abstract
Antenatal depression affects about 20% of pregnant women/wāhine globally, increasing pregnancy complications and postnatal depression. Psychotherapy is recommended but is often inaccessible due to cost, time, and stigma. Antidepressants are advised for severe cases, but only 3% of pregnant wāhine in Aotearoa use them, often due to infant health concerns. Poor nutrition during pregnancy is linked to higher maternal depression.
Our research showed that additional micronutrients (vitamins and minerals) during pregnancy for the treatment of symptoms of antenatal depression improved birth outcomes and may mitigate depression’s negative effects. These results highlight potential healthcare savings and the need for policy development to improve diets and prescribe micronutrients during pregnancy, especially for low-income New Zealanders.
The data also suggest the need to consider improving nutrition in pregnancy (e.g., vouchers for whole foods), and for consideration around the routine promotion or prescribing of micronutrient supplements by the NZ Government and relevant professional groups.
