Comparison of evening and nocturnal food intake for night eaters and controls.

Variable Night Eater
M ± SD		 Control
M± SD		 Statistic, Significance
Dinner to awakening (% of TDCI) 65.3 ± 13.9 41.6 ± 8.3 t (39) = 6.8, p < 0.001
After dinner to awakening (% of TDCI) 49.8 ± 14.6 13.3 ± 11.8 t (39) = 8.9, p < 0.001
After dinner to bedtime (% of TDCI) 32.2 ± 18.6 13.2 ± 11.8 t (39) = 4.0, p < 0.001
After bedtime to awakening (% of TDCI) 17.9 ± 13.4 0.0 ± 0.1 t (39) = 6.3 p < 0.001
Nocturnal Awakenings per Week 12.6 ± 8.3 1.4 ± 1.9 t (39) = 6.1, p < 0.001
Nocturnal Ingestions per Week 9.6 ± 7.8 0.1 ± 0.2 t (39) = 5.8, p < 0.001
Morning Hunger before 1st meal (0–100) 26.4 ± 24.3 58.0 ± 20.2 t (35) = 4.3, p < 0.001

Note. Dinner refers to the evening meal, defined as the first meal initiated between 17:00 and 20:00 hrs. If no meal was eaten during this time on a given day, the average dinner time across the remaining days was taken, and any intake after that time was considered “after dinner”; TDCI = total daily caloric intake.
