“…Sabe-se atualmente que cada indivíduo possui necessidades de horas de sono distintas, variando com a idade, o sexo e até mesmo com a sua localização geográfica (UR-SIN; BJORVATN; HOLSTEN, 2005), contudo, Hirshkowitz et al (2015) relatam que a National Sleep Foundation recomenda de sete a nove horas de sono por noite para a faixa etária média deste estudo. Já o valor encontrado com a amostra do curso de medicina evidenciou um valor inferir ao recomendado.…”

INTRODUÇÃO É provável que o ser humano não perceba o fato de que aproximadamente um terço de sua vida seja dedicado ao ato de dormir, um período que é associado um padrão comportamental e eletroencefalográfico especifico (HOBSON, 1999). Apesar das inúmeras teorias propostas para explicá-lo, não existe na atualidade uma que inspire confiança em que toda a sua essência tenha sido estabelecida (CHOKROVERTY, 2009). De acordo com Reimão (1990): "O sono é definido como um estado funcional, cíclico e reversível, com manifestações comportamentais próprias do momento".Sabe-se que para a organização do ciclo circadiano três processos básicos encontram-se envolvidos: o Homeostático, o Ultradiano e o Circadiano (TALHADA, 2012). Embora separados, é a interação entre estes processos que determina a distribuição temporal e duração do sono e da vigília (TUKER; ZEE, 1999). Alterações na cadência circadiana são acompanhadas por alterações no sono, que podendo acarretar prejuízos biopsicossociais. Cardoso et al. (2009) inferem que o homem precisa de estabilidade de seu padrão do sono, em razão da interferência direta nas funções biológicas e, sobretudo, na consolidação da memória, visão, termorregulação, conversão e restauração de energia, extensivo à restauração do metabolismo energético cerebral.

“…Thus, sufficient sleep duration requirements vary throughout the life span and from person to person. Individuals who usually sleep out of the normal pattern may be exhibiting signs or symptoms of serious health problems and this may compromise their well-being (Hirshkowitz et al 2015).…”

Is the perception of school-aged children and parents about the children's sleep quality and chronotype consistent with their real sleep quality and effective chronotype? The research questions for this study were 1) Do children's sleep perceptions and chronotype differ from real sleep quality and chronotype? 2) Are there differences in sleep quality between genders? 3) What will be the effective quality of sleep and chronotype? The purpose of the study was to analyse the perceptions of children and parents about the children's sleep quality and chronotype and compare them with effective sleep quality and chronotype, to study sleep quality and chronotype considering gender, and to analyse the perceptions of Portuguese parents about children's sleep in a migrant context. The research method was a cross-sectional study, quantitative methodology. The data from three questionnaires were analysed with regard to the three study aims: the Pittsburgh Sleep Quality Index (PSQI) (n=1109 children), the Children's Sleep Habits Questionnaire (CSHQ) (n=883 parents), and the Children's Chronotype Questionnaire (CCTQ) (n=58 parents, Portuguese emigrants in Luxembourg). The samples were collected from 8 Portuguese schools and 2 Luxembourg schools. The PSQI showed high sleep quality, which contradicts the results for CSHQ. Children from state schools (n=538) revealed higher diurnal dysfunction levels compared to the children from private schools (n=571). Females showed best sleep latency and duration. The CSHQ presented general negative sleep quality. The CCTQ demonstrated that parents' perceptions did not fit with the effective children's chronotype. The children's perception showed a wellbalanced sleep quality but the results revealed a high incidence of sleep disturbance. There were no statistical differences for gender. Portuguese emigrant parents revealed low awareness of their children's chronotype and there was significant contrast between parents' perceptions and the real chronotype of children.
