Brief Summary:

Globally, vitamin B12 deficiency is one of the most common micronutrient deficiencies. Poor status is also seen in affluent countries such as in Norway. Vitamin B12 is crucial for normal cell division and differentiation and necessary for the development and myelination of the central nervous system. Deficiency is also associated with impaired fetal and infant growth. In the proposed study we will measure the effect of daily oral vitamin B12 supplementation infants on neurodevelopment. We also aim to measure the impact of B12 supplementation on several other outcomes.

Study design: Individually randomized double-blind placebo-controlled trial breastfed infants who will be assigned to a screening group (in which measurements will be obtained immediately) or a control group (in which serum will be stored and measurements done after one year).

Pregnant women will be informed about the study during their first antenatal visit at the clinic and that we will re-approach them on their 6-week visit to their public health nurse. Infants who are deficient will be treated with peroral or intramuscular injections with 400 µg cyano-cobalamin.

Infants in the control group will not be offered any intervention their blood sample will be stored for one year and then analyzed for the same nutrients as the intervention group.

Outcomes: Primary: (i) neurodevelopment in children measured at 12 months of age (ii) growth in children measured by attained weight and length at 12 months. Secondary: (i) neurodevelopment and cognitive functioning in children later in life

Arm Intervention/treatment
Experimental: Screening - treatment
From 6 weeks of age, infants will be screened for elevated plasma total homocysteine concentrations. Those who have a concentration above the defined cut-off will be treated with cobalamin (vitamin B12).
Biological: Cyanocobalamin
Intramuscular injection of 400 µg cobalamin to children with elevated thcy at enrollment
Other Name: Vitamin B12

No Intervention: Control
The control-group sample will be stored and analyzed when the child is 12 months old. Those with elevated tHcy will contribute to the control group.

Primary Outcome Measures :
  1. Neurodevelopment [ Time Frame: 12 months of age ]
    Bayley Scales of Infant Development 4th edition

  2. Prevalence of vitamin B12 deficiency [ Time Frame: 1-3 months of age ]
    Number of children with elevated plasma homocysteine or low cobalamin

  3. Prevalence of other vitamin deficiencies [ Time Frame: 1-3 months of age ]
    Number of infants with vitamin deficiencies other than vitamin B12 deficiency

Secondary Outcome Measures :
  1. Neurodevelopment measured by the Ages and Stages Questionaire [ Time Frame: 4-12 months of age ]

  2. Vagal tone [ Time Frame: 12 months of age ]
    Heart rate variability

  3. Eye tracking [ Time Frame: 12 months of age ]
    Visual acuity, visuospatial orientation, and attention to social cues

  4. Neurodevelopment later in childhood [ Time Frame: 5 years ]
    General cognitive abilities ("IQ") assessed by the Wechsler Preschool and Primary Scale of Intelligence

  5. Adverse events [ Time Frame: 3 months after treatment with vitamin B12 ]
    Number of participants with treatment-related adverse events as assessed by CTCAE v4.0

Other Outcome Measures:
  1. Thyroid function [ Time Frame: 12 months of age ]
    Infant thyroid function measured by the concentration of the hormones TSH, T3, and T4
