Adolescent sleep delay has been well-documented and is related to greater social pressures as well as to ontogenetic trends. As a consequence, a partial sleep deprivation is observed and morning school routine can promote excessive daytime sleepiness during schooldays and a poorly academic performance. Some studies have pointed out the positive effect of sleep educational programs. This study aimed to evaluate the effect of an Educational Sleep Program (ESP) on adolescent sleep/wake cycle, subjective sleepiness and psychomotor vigilance performance. 21 adolescents (13-14y) of a public school in Curitiba – Brazil participated in the study. Two groups were formed: Experimental (n=10), submitted to the EPS, and Control (n=11), not submitted to the EPS. Sleep/wake cycle data, onset, offset, sleep duration and sleep efficiency were recorded with actimeters; subjective sleepiness were obtained by means Karolinska Sleepiness Scale and psychomotor performance were performed by means Psychomotor Vigilance Task (PVT), before and after the ESP. The ESP consisted in activities related to the importance of sleep and sleep hygiene. It lasted four hours. Data of sleep patterns, psychomotor performance subjective sleepiness were compared by means two-way ANOVA for dependent samples - treatment (before or after intervention) and group (Control and Experimental) were considered factors. Results did not show any EPS effect on adolescents sleep/wake pattern, subjective sleepiness and psychomotor performance. Further studies with longer ESPs should be carried out to evaluate the validity of such programs as a countermeasure to prevent excessive daytime sleepiness among adolescents.
