A Canadian study recently examined the effects of breastfeeding and pumping when it comes to infant weight gain and obesity risk. The study involved data from approximately 2,500 infants collected from the Canadian Healthy Infant Longitudinal Development study. Results indicated that 12-month-old infants with the lowest body mass index scores were exclusively breastfed. Compared to babies who received pump breast milk, the exclusively breastfed babies also had slower weight gain.
Study authors believe that this information could impact a child’s risk of becoming overweight or obese later in life. It reinforces the many benefits of breastmilk, and researchers believe it sends a message to policymakers about support for breastfeeding and parental leave.
These findings were published in Pediatrics on September 24, 2018.
