PEREIRA, Érico Felden; BERNARDO, Maria Perpeto Socorro Leite; D'ALMEIDA, Vânia  e  LOUZADA, Fernando Mazzilli. Sleep, work, and study: sleep duration in working and non-working students. Cad. Saúde Pública [online]. 2011, vol.27, n.5, pp.975-984. ISSN 0102-311X.  http://dx.doi.org/10.1590/S0102-311X2011000500015.

The aim of this study was to investigate the duration of sleep and associated factors in working and non-working students. Data were analyzed on the sleep-wake cycle in 863 teenage students in São Paulo, Brazil. Adjusted analyses were performed to compare sleep duration in working and non-working students. 18.4% of the group worked, and 52% of the working students slept eight hours or less per night. Prevalence of short sleep duration was higher in working students of both sexes (males, p = 0.017; females, p < 0.001). Working students showed short sleep duration in the analysis adjusted for socioeconomic status, but short sleep was more frequent in older adolescents (p = 0.004) and in lower (p = 0.001) and middle (p = 0.011) socioeconomic classes. Although more working students were in night school, in the model adjusted for gender and socioeconomic status, working students in afternoon courses showed higher prevalence of short sleep duration (PR = 2.53; 95%CI: 1.68-4.12).
