Abstract

We examined satiety quotient (SQ) and energy intake (EI) according to sleep duration, quality and timing. Seventy-five overweight/obese men (age: 41.1±5.8 years; body mass index: 33.6±2.9 kg/m(2)) completed visual analogue scales for appetite sensations before, immediately after and every 10 minutes for 1 hour following a standardized breakfast. The mean SQ (primary outcome of the study) was calculated from four appetite sensations. The Pittsburgh Sleep Quality Index identified short-duration (<7 h/night) and 'recommended sleep duration' (7 h/night) sleepers, poor (score 5)- and good (score <5)-quality sleepers and late (midpoint of sleep >0230 hours) and early (midpoint of sleep 0230 hours) sleepers. A 3-day food record and buffet-style meal assessed the EI. Short-duration sleepers had a lower mean SQ compared with recommended sleep duration sleepers (6.5±4.9 vs 8.8±4.3 mm/100 kcal; P=0.04). The mean SQ between poor and good (6.9±4.6 vs 8.7±4.6 mm/100 kcal; P=0.11) and that between early and late (8.99±5.10 vs 9.32±4.02 mm/100 kcal; P=0.78) sleepers were not significantly different. EI did not differ between the sleep groups. Thus, short-duration sleepers had a lower mean SQ compared with recommended sleep duration sleepers. However, this did not coincide with an increased EI.
