Estimated model-based mean cortisol values as a function of time since awakening, by sexual orientation among female and male participants ages 18–32 years in the Growing Up Today Study (GUTS) Saliva Substudy. Notes: estimates based on model presented in Table 3. Saliva sample times: sample 1 = 0 from waking; sample 2 = 45 min from waking; sample 3 = 4 from waking; sample 4 = 10 from waking; sample 5 = before bed. No significant differences in cortisol were seen across sexual orientation groups.
