Outcome is mean logarithmic-transformed diurnal cortisol levels (nmol/L).

Adversity count and psychological health (sum of z-scores of: depression and anxiety symptoms (both inversed) and positive affect; higher scores indicate better functioning) are standardized. Lower adversity is 0–2 adversity types, higher adversity is 3+ adversity types.

Model 1: age (continuous, mean centered) and sex (reference=male).

Model 2: Model 1 and race (reference=white), sexual orientation (reference=heterosexual), and father’s educational attainment (reference=4-year college or grad school).

Model 3: Model 2 and BMI (continuous, mean centered), time to cortisol assessment (continuous, mean centered), hormonal contraception use (reference=no use), sleep duration (continuous, mean centered) waking time (continuous, mean centered), smoking (reference=no smoking), and vigorous physical activity (reference=no physical activity).

Effects p<.05 are bolded. Effects p<.10 are italicized.
