#P-value for sex interaction term <0.05; sexes combined for cortisol due to a lack of evidence for sex interaction; occupational class was that of the highest in the household and derived using the Registrar General's classification; Analyses using lifetime SEP score (and all AIC calculations) were restricted to those with valid data for all SEP indicators and each hormone.
