Research progress on correlation between antibiotic exposure in early life and childhood obesity

Abstract

Childhood obesity continues to be a public health concern worldwide, which seriously affects children′s health.In recent years, children have been generally exposed to low doses of antibiotics, and antibiotic problem has drawn international attention.Domestic and foreign researches show that antibiotic exposure in the early life of children is associated with childhood obesity risk, while its specific mechanism has not been completely clear.It is possible that antibiotics may lead to changes in the normal intestinal flora colonization of infants and young children and damage the early intestinal microflora, thus increasing the risk of childhood obesity, but further research is needed to confirm this causal mechanism. Key words: Early life; Antibiotic exposure; Child; Obesity; Intestinal flora
