Key Points

Question  How do infant feeding practices influence gut microbiota and risk of overweight?

Findings  Among 1087 infants from the Canadian Healthy Infant Longitudinal Development (CHILD) cohort, earlier cessation of breastfeeding and supplementation with formula (more so than complementary foods) were associated with a dose-dependent increase in risk of overweight by age 12 months; this association was partially explained by specific gut microbiota features at 3 to 4 months. Subtle but significant microbiota differences were observed after brief exposure to formula limited to the birth hospital stay, but these differences were not associated with overweight.

Meaning  Breastfeeding may contribute to protection against overweight by modifying the gut microbiota, particularly during early infancy.

JAMA Pediatrics: Early Animal Exposure and Childhood Illnesses

animals and allergies

Based on more current research studies, we now understand that exposing children to pets early in life does not lead to an increased risk of allergies or autoimmune illnesses. A study in this month’s issue of JAMA Pediatrics evaluated dog exposure among children beginning at 1 year. The researchers evaluated the children annually for several years and found that there was no association between early exposure to dogs and developing type 1 diabetes in childhood. Other studies have found that exposure to pets early in life may contribute to a decreased risk of developing allergies.
