Here's why breastfeeding is important for infants

Seoul: New mommies, please take note. A new study has revealed that breastfeeding can protect the high-birthweight infants from being overweight or obese in childhood.

Lead study author Hae Soon Kim, from the Ewha Womans University College of Medicine in Seoul, said "High birthweight is associated with overweight or obesity during early childhood. Among high-birthweight infants, exclusive breastfeeding is a significant protective factor against overweight and obesity."

Researchers investigated the weight-growth trajectory and the protective effect of breastfeeding for obesity in children, for the study.

Researchers analysed data between January 1, 2008 and December 31, 2016. They followed 38,039 participants who were completely eligible for all health checkups from birth through six years of age.

The researchers examined the association between birthweight status and growth development at each check-up period.

Infants were assigned to one of three groups by birthweight: the low-birthweight group, less than or equal to 2,500 grams; the normal-birthweight group, over 2,500 grams and under 4,000 grams; and the high-birthweight group, 4,000 grams or more.

During the follow-up period, about 10 per cent of the low-birthweight infants and 15 per cent of the normal-birthweight developed obesity or overweight. By contrast, more than 25 per cent of the high-birthweight infants met the criteria for obesity or overweight.

The high-birthweight infants were highly likely to be overweight or have obesity compared with normal birthweight infants through six years of age, and the low-birthweight infants were highly likely to be underweight through six years of age, the researchers said.

They noted, the risk of overweight or obesity decreased significantly if high-birthweight infants were exclusively breastfed for the first six months of life.

The study was presented at the ENDO 2018: The Endocrine Society's 100th Annual Meeting and Expo.
