Summary

Researchers examined whether plastic bottle use at three months of age was associated with infant growth, gut microbiota, and short-chain fatty acid levels over the first year of life. They found that plastic bottle frequency was not strongly linked to measures of body fat or growth, and initial associations with gut bacteria were weakened after adjusting for diet. The study calls for further research into health effects from other plastic-based products and direct measurements of microplastic exposure in infants.

Plastic bottle frequency at 3 months was not strongly associated with measures of adiposity or growth (save for length-for-age) over the first year of life, and while plastic bottle use was associated with some features of fecal microbiota and SCFAs in the first year, these findings were attenuated in multivariable models with infant diet. Future research is needed to assess health effects of exposure to other plastic-based products and objective measures of microplastics and plastic constituents like phthalates.

Associations of Plastic Bottle Exposure with Infant Fecal Microbiota, Short-Chain Fatty Acids, and Growth

Researchers investigated associations between plastic bottle use and infant gut health, examining whether exposure influences early fecal microbiota composition, short-chain fatty acid levels, and growth trajectories in infants.

Detection of Microplastics in Human Breast Milk and Its Association with Changes in Human Milk Bacterial Microbiota

Researchers detected microplastics in nearly 39% of breast milk samples from 59 mothers, with polypropylene and polyethylene being the most common types found. The presence of microplastics was linked to changes in the bacterial makeup of breast milk, raising concerns about early-life microplastic exposure in infants during breastfeeding.

Exposure to polyethylene microplastics alters immature gut microbiome in an infant in vitro gut model

Researchers used an artificial infant gut model to study how chronic exposure to polyethylene microplastics affects the developing intestinal microbiome. They found that microplastics shifted gut microbial composition, increasing the abundance of potentially harmful bacteria such as Enterobacteriaceae while decreasing beneficial butyrate production. The study suggests that microplastic ingestion may disrupt the gut microbiome of infants, though no significant damage to the intestinal barrier was observed.

Occurrence of Polyethylene Terephthalate and Polycarbonate Microplastics in Infant and Adult Feces

Researchers measured microplastic levels in the stool of infants and adults in New York and found that infants had significantly higher concentrations of PET microplastics, about ten times more than adults. The likely sources include plastic baby bottles, food packaging, and toys that infants frequently put in their mouths. This study provides some of the first direct evidence that babies are exposed to more microplastics than adults, raising questions about potential health effects during early development.

Detection of various microplastics in placentas, meconium, infant feces, breastmilk and infant formula: A pilot prospective study

In a pilot study of 18 mother-infant pairs, researchers detected microplastics in placentas, meconium (first stool), infant feces, breast milk, and infant formula. The finding of microplastics in breast milk and formula means that infants are exposed to microplastics from their earliest feedings, both natural and artificial. This study reveals that microplastic exposure begins before birth and continues through infancy, a critical period of development.
