Infant vitamin B12 status and its predictors - cross-sectional baseline results from an ongoing randomized controlled trial.

ABSTRACT:

Background

Vitamin B12 is a crucial micronutrient for infant growth and development.

Objective

The objective of this study was to describe vitamin B12 status in Norwegian infants aged 6-15 wk using multiple biomarkers and cut-off approaches, and to identify its predictors.

Methods

From November 2021 through August 2024, infants aged 6-15 wk and their mothers were recruited from public health clinics in Innlandet County, Norway, as part of an ongoing randomized controlled trial. Plasma cobalamin and methylmalonic acid (MMA) concentrations were analyzed among all infants in the cohort (n = 644), and total homocysteine (tHcy) concentrations were analyzed in a subgroup (n = 358). The combined indicator for vitamin B12 status (cB12) was calculated by Fedosov's equation. Lo
