*Significant at t ≥ ±1.96 level. SLEEP: number of hours sleep in the 72 hours prior to the study; AA: RBC membrane arachidonic acid, as measured in absolute amounts (μg/mL); DHA: RBC membrane docosahexaenoic acid, as measured in absolute amounts (μg/mL); WAIST: waist circumference; PSS-Overwhelm: latent factor loading PSS-10 questions 6, 10, 2, and 8, where 8 was negatively loaded; PSS-Coping: latent factor loading PSS-10 questions 7, 5, and 4; PSS-Emotional: latent factor loading PSS-10 questions 1, 3, and 9.
