    Publication . Saraiva, Ana Gabriela da Silva; Chaves, Cláudia Margarida Correia Balula; Duarte, João Carvalho; Amaral, Maria Odete Pereira
    Enquadramento: Os estudantes de enfermagem, pelos conhecimentos adquiridos ao longo do curso, devem estar conscientes dos malefícios do tabagismo. Objetivos: Estimar a prevalência de consumo de tabaco e identificar as variáveis sociodemográficas, académicas e psicológicas, associadas à dependência de nicotina, em estudantes de enfermagem. Metodologia: Estudo transversal analítico. Amostra de 404 estudantes de enfermagem, 86,1% género feminino (M=23,60±6,67 anos). Questionário constituído por variáveis sociodemográficas e académicas, Escala de ansiedade, Depressão e Stresse, Escala de Afeto Positivo e Negativo, o Teste Fagerström da Dependência à Nicotina e o Inventário de Personalidade de Eysenck. Resultados: Prevalência de consumo de tabaco de 25,2%, género masculino com uma percentagem maior (32,1% vs. 24,1%). Os estudantes começaram a fumar aos 16,8 anos. Dos estudantes que começaram a fumar antes dos 15 anos, 44,4% apresentam um nível de dependência elevado. O consumo de tabaco associou-se à extroversão e ao stresse. Conclusão: Um quarto dos estudantes fumam e o consumo associou-se com variáveis psicológicas. Há necessidade da criação e implementação de intervenções de dissuasão do consumo de substâncias psicoativas.

    Publication . Amaral, Maria Odete Pereira; Garrido, António José de Almeida; Pereira, Carlos de Figueiredo; Veiga, Nélio; Nunes, Carla de Rosário Delgado; Sakellarides, Constantino Theodor
    Objectives: To determine the prevalence of insomnia in a sample of Portuguese adolescents and assess its repercussions on HRQoL, daytime sleepiness and depressive symptomatology. Design: We carried out a cross-sectional school-based study evaluating students from Viseu. Location: Students from twenty-six public secondary schools in the county of Viseu, Portugal. Participants: Of 9237 questionnaires distributed, 7581 were collected (82.1%). We excluded from analysis all questionnaires from adolescents younger than 12 or older than 18 years of age (211) and unfilled forms (451). The sample comprised 6919 adolescents, the 7th to 12th grade, from 26 public secondary schools. Interventions: None. Measurements: Data gathering was done using a self-applied questionnaire. Insomnia was defined based on the Diagnostic and Statistical Manual of Mental Disorders -- IV criteria. HRQoL was evaluated with the Quality of Life Health Survey SF-36, depressive symptomatology with BDI-II and daytime sleepiness with the Epworth Sleepiness Scale. Results: Prevalence of insomnia was 8.3% and the prevalence of adolescents with symptoms of insomnia without daytime impairment (disturbed sleepers) was 13.1%. HRQoL was significantly reduced among adolescents with insomnia compared to normal sleepers (p < 0.001) and even when compared to disturbed sleepers (p < 0.001). There was an increase in daytime sleepiness from normal sleepers to disturbed sleepers and to adolescents with insomnia (p < 0.001). There was also an increase in the prevalence and severity of depressive symptoms (p < 0.001). Conclusions: Our results show that insomnia is associated with a significantly lower health related quality of life among adolescents.
