Outcome Measures

Primary Outcomes (1)

  • Nutrient status during pregnancy

    Nutrient deficiencies during each trimester of pregnancy. Nutrients of primary interest include ferritin, folic acid, vitamin A-D-B12 and albumin.

    Nutrient status was preferably assessed at 4 occasions: During trimester 1 (week 1-12), trimester 2 (week 13-26), trimester 3 (week 27-42) and at 2 months post-partum.

Secondary Outcomes (2)

  • Neonatal birth weight

    Directly after delivery/birth

  • Gestational weight gain

    From the beginning of pregnancy (max 3 months before conception until 1 month after conception) until date of delivery (max 2 weeks before event)

Other Outcomes (3)

  • Use of supplementation

    At trimester 1 (week 1-12), trimester 2 (week 13-26), trimester 3 (week 27-42) and at 2 months post-partum.

  • Surgery characteristics

    At estimated date of conception (first day of last menstrual period + 14 days)

  • Pregnancy outcomes

    From the estimated date of conception (first day of last menstrual period + 14 days) until date of delivery
