Psychoneuroendocrinology: Pre-birth stress can affect the gut flora of infants.

, June 24, 2020 /PRNewswire/ --- A recent study published by the University of Turku in Finland showed that the mother's chronic prenatal psychological distress and elevated hair cortisol concentrations were associated with the composition of the baby's gut floraThe results help to better understand how prenatal stress affects infant growth and developmentThe study has been published in the journal Psychoneuroendonologyprevious studies have shown that prenatal stress may be associated with the growth and development of infantsHowever, the molecular mechanisms are not yet fully understood"We have shown that long-term psychological distress in pregnant women and increased hair cortisol during pregnancy are associated with the composition of the baby's gut flora," said the author, DrAatsinkithe study measured the average concentration of cortisol in a pregnant woman over a period of several months by analyzing hair cortisolIn addition, the mother's symptoms were assessed three times during pregnancyInfant intestinal flora was analyzed by genetic sequencing at 2.5 months of agemorphite and Lactobacillus are common intestinal microbes in infants"We found that the mother's chronic prenatal psychological distress was associated with an increase in the number of morphobacteria in the infant microbiomeIn addition, chronic psychological symptoms are associated with a decrease in the number of Akkermansia genus, which is thought to promote at least adult health," Aatsinki saidAccording to Aatsinki, low cortisol levels are associated with increased abundance of Lactobacillus in infant gut flora, which is thought to promote health"Our study does not explain the causalrelationship or whether prenatal stress is associated with differences in microbial metabolites or immune system function," saidAatsinkiFurther research is needed to answer these important questions " (Bio Valley Bioon.com) information source : -
