P < 0.05 compared to the first tertile.
a
Data are presented as mean ± SEM.
b
Fitness tertiles were based on a 10 pt Likert scale: low (1–4), medium (5–7), high (8–10).
c
Stress: low (“relatively little” or “almost no” stress), medium (“moderate”), high (“a lot”).
d
Fruit intake: low (0 or 1 serving/day), medium (2 servings/day), high (3 or more servings/day).
