Breastfeeding promotion and support,
does it really help with Reduced infant gastrointestinal infection through 12 months?
research showsThe grade is B. PROBIT cluster-randomized a breastfeeding promotion and support program at 31 maternity facilities, not breastfeeding itself. In the original cluster-adjusted analysis, infant gastrointestinal infection was 9.1% versus 13.2%, adjusted OR 0.60 (95% CI 0.40 to 0.91). Infant eczema also decreased, but asthma, allergy, obesity, and adiposity at age 6.5 years did not, so this must not be read as breastfeeding preventing many diseases.
ads claimThe trial did not randomize breastfeeding itself. It randomized facility promotion and support, and claims must separate the outcomes that decreased from those that did not.
Useful facts when choosing a product
- Exclusive breastfeeding at three months was 43.3% at intervention facilities versus 6.4% at usual-care facilities.
- Gastrointestinal infection was 9.1% versus 13.2%, while respiratory infection was 39.2% versus 39.4%.
- Verdict 1567 is C with 58 points and addresses six-month breastfeeding continuation; this verdict addresses the separate 12-month gastrointestinal-infection outcome.
What the research actually shows
PROBIT cluster-randomized 31 Belarusian maternity hospitals and affiliated polyclinics, 16 versus 15. The 2001 report records 16,491 of 17,046 pairs completing 12-month follow-up, whereas the 2014 cohort profile records 16,492, a one-pair source difference. Gastrointestinal infection was 9.1% versus 13.2%, OR 0.60 (0.40 to 0.91), in analysis accounting for facility clustering. Infant eczema was positive, while asthma, allergy, obesity, and adiposity at age 6.5 years were all null. The trial ran in 1996-1997 and was registered much later.
Why this is classified as B (72)
A large cluster-randomized trial reduced infant gastrointestinal infection after cluster adjustment. Retrospective registration, lack of provider and assessor blinding, possible record-confirmation bias, and one-country one-period data give B with 72 points.
Counterpoint. Belarus had a centralized health system and routine six-to-seven-day postpartum stays. The result does not directly generalize to preterm or ill infants or families without an initial intention to breastfeed.
Rejudgment record. Cross-check applied — Cluster-adjusted gastrointestinal infection reduction after facility randomization, limited by retrospective registration, no provider or assessor blinding, possible record-confirmation bias, and one-country one-period data

Sub-claim grades by effect
This ingredient is marketed for several effects. A single overall grade blends strong and weak claims together, so each effect is graded separately here. The overall grade reflects the strongest disconfirming or core claim.
| Effect (sub-claim) | Grade | Basis |
|---|---|---|
| Reduced gastrointestinal infection | B | The cluster-adjusted OR was 0.60. |
| Reduced respiratory infection | D | Rates were 39.2% versus 39.4%, with no significant difference. |
