The composition of human milk is subject to considerable
variation, but the effects of maternal stress are largely unknown. We
studied differences in human milk metabolome between Finnish mothers (n = 120,
secretors) with symptoms of prenatal symptoms of psychological distress
and milk cortisol concentrations. Human milk samples acquired at
2.5 months postpartum were analyzed using targeted 1H NMR metabolomics.
Self-reported scores for depression (EPDS), overall anxiety (SCL-90),
and pregnancy-related anxiety (PRAQ) were used to evaluate psychological
distress. Prenatal psychological distress was positively associated
with concentrations of short-chain fatty acids, caprate, and
hypoxanthine (q < 0.0012). Milk cortisol was positively associated with lactate concentration (q < 0.05).
Changes in the human milk metabolome were shown to be associated with
maternal psychological distress and concentration of milk cortisol in a
dissimilarly, suggesting alterations in bacterial and energy metabolism
of the mother, respectively.
