Separation from the mother in rodents induces physiological and behavioural responses including vocalisation and searching behaviour, corticosterone hormone release and inhibition of metabolism related to growth and
later stress reactivity [129, 130].

Adiposity moderates links from early adversity and depressive symptoms to inflammatory
reactivity to acute
stress during
late adolescence.
The pioneering research by Meaney and colleagues [135] has shown that, in rats, stable individual differences in maternal care are related to individual differences in pups»
later behaviour and
stress reactivity.
The second hypothesis for this study was whether neonatal
reactivity (rated from the NNNS and Cry scales) would predict
later maternal ratings of infant temperament, and whether parenting
stress and psychopathology would moderate such relations.
Thus, maternal characteristics (
stress and psychopathology) interacted with neonatal
reactivity to explain variability in
later maternal ratings of parenting
stress and maternal ratings of infant temperament.
Rather, these findings suggest that the degree to which neonatal
reactivity explains variation in
later maternal ratings of infant temperament is dependent on the general level of parenting
stress experienced by mothers, regardless of whether they had used cocaine and / or opiates during pregnancy.
In Study 2, the participants were 32 remitted - depressed and 36 never - depressed young adults who completed a psychosocial
stress task to determine cortisol
reactivity and were reassessed for depression and
stress approximately 8 months
later.
