Adherence and tolerability of iron-containing prenatal multivitamins in pregnant women with pre-existing gastrointestinal conditions
Bibliographic record
Abstract
Prenatal multivitamin supplements (PMS) are recommended during pregnancy. Suboptimal adherence in women experiencing gastrointestinal (GI) conditions is thought to be attributed to the high elemental iron content in PMS. This study sought to quantify adherence and tolerability of iron-containing PMS in women with pre-existing GI conditions by recruiting women who called the Motherisk Helpline. Women with (n = 36) and without (n = 166) pre-existing GI conditions were randomised to either PregVit (n = 106) or Orifer F (n = 96). Monthly follow-up interviews were conducted to assess pill intake and GI adverse effects associated with PMS. The results of our study suggest that with the use of small size and low dose iron PMS, women with pre-existing GI conditions do not experience (1) more GI adverse effects, (2) lower adherence than women with no such conditions, and (3) may experience less severe nausea and vomiting of pregnancy. Supplementing with small tablets of low dose iron PMS should be considered.

How this classification was reachedexpand
Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one teacher head, not a consensus.
