Chennai: Scientists have claimed that bacteria in meconium — the earliest stool of an infant — may indicate their risk of obesity.
Meconium is composed of materials ingested during the time the infant spends in the uterus.The study, published in the journal Pediatric Obesity, Obesity found that the types of normal bacteria found in the meconium may predict an infant’s likelihood of later developing obesity.
Many studies have shown that the first-pass meconium hosts a diverse microbiome, but its clinical significance is not known.
Accordign to study authors from the University of Oulu in Finland, “we designed a prospective population based cohort study to evaluate whether the meconium microbiome predicts subsequent growth in children.”
In the study of 212 newborns, children who became overweight at three years of age differed in their meconium bacterial makeup from those with normal weight, having a higher proportion of bacteria in the Bacteroidetes phylum (29 per cent versus 15 per cent).
