The Claim

Daily zinc supplementation of 5 mg elemental zinc from birth to 12 months of age reduces diarrheal incidence from 1.93 to 1.36 episodes per child per year in low birth weight infants in urban India, with a relative risk of 1.4 (95% CI: 1.02–2.00), indicating a statistically borderline but clinically relevant reduction in diarrheal burden in this vulnerable population.

In plain English

In low birth weight infants in urban India, taking 5 mg of elemental zinc daily from birth to 12 months of age results in a reduction in diarrheal episodes from 1.93 to 1.36 per child per year.

See the scientific wording

Daily zinc supplementation of 5 mg elemental zinc from birth to 12 months of age reduces diarrheal incidence from 1.93 to 1.36 episodes per child per year in low birth weight infants in urban India, with a relative risk of 1.4 (95% CI: 1.02–2.00), indicating a statistically borderline but clinically relevant reduction in diarrheal burden in this vulnerable population.

Why this might work

Zinc strengthens the lining of the gut and helps immune cells in the intestine fight off germs that cause diarrhea, so fewer germs get into the body and cause illness.

  1. Study: Impact of zinc supplementation on diarrheal morbidity and growth pattern of low birth weight infants in kolkata, India: a randomized, double-blind, placebo-controlled, community-based study.

    Giving babies who are born small a daily zinc supplement for their first year helped them get fewer diarrhea episodes, from almost 2 per year down to about 1.4, even though breastfeeding also helped protect them.
