The role of zinc and iron-folic acid supplementation on early child temperament and eating behaviors in rural Nepal: a randomized controlled trial.

What Was Tested

Researchers studied Vitamin D, K2, Magnesium and Zinc in this randomized controlled trial publication.

Child eating behaviors play an important role in nutrient intake, ultimately affecting child growth and later outcomes in adulthood.

The study assessed the effects of iron-folic acid and zinc supplementation on child temperament and child eating behaviors in rural Nepal.

Who Took Part

PubMed indexes the participants as infants, both men and women.

The main effects of zinc and iron-folic acid supplementation on temperament and eating behaviors were assessed through crude and adjusted differences in mean cumulative score changes between visits 1 and 5.

How the Study Was Run

The design is described as randomized and placebo-controlled.

Random assignment meant chance, not the researchers, decided who got Vitamin D, K2, Magnesium and Zinc and who got the comparison, which limits bias.

Some participants received a placebo instead of Vitamin D, K2, Magnesium and Zinc, giving a reference point.

What Was Measured

Child eating behaviors play an important role in nutrient intake, ultimately affecting child growth and later outcomes in adulthood.

The study assessed the effects of iron-folic acid and zinc supplementation on child temperament and child eating behaviors in rural Nepal.
