چکیده
Objective: to investigate the association between clinical progression and the quality and duration of sleep in women with breast cancer. Method: longitudinal study, with 114 participants, conducted in a hospital in Brazil. The instruments used were: questionnaire for sociodemographic and clinical characterization, Pittsburgh Sleep Quality Index; Beck Depression Inventory and Herth Hope Scale. Data were analyzed through descriptive statistics and survival analyses (outcome: poor clinical progression), using the Kaplan-Meier curve, Log-rank test and Cox proportional model. Results: a higher probability of poor clinical progression was verified in women with sleep durations of less than six hours or nine hours and over (p=.0173). Conclusion: the results suggest the importance of further studies that seek to verify whether the quantitative management of sleep disorders would have an impact on the progression of breast cancer. Women should be encouraged to report sleep problems to nurses. Objetivo: mensurar a associação entre evolução clínica e qualidade e duração do sono em mulheres com câncer de mama. Método: estudo longitudinal, com 114 participantes, realizado em um hospital do Brasil. Os instrumentos utilizados foram: questionário para caracterização sociodemográfica e clínica, Índice de Qualidade do Sono de Pittsburgh; Inventário de Depressão de Beck e Escala de Esperança de Herth. Os dados foram analisados via análises descritivas e de sobrevivência (resultado: evolução clínica desfavorável), utilizando-se a curva de Kaplan-Meier, o teste log-rank e o modelo proporcional de Cox. Resultados: verificou-se maior probabilidade de evolução clínica desfavorável em mulheres com duração de sono inferior a seis ou mais de nove horas (p = 0,0173). Conclusão: os resultados sugerem a importância de mais estudos que buscam verificar se a gestão quantitativa dos distúrbios do sono teria um impacto sobre a evolução do câncer de mama. As mulheres devem ser encorajadas a relatar isso espontaneamente aos enfermeiros. Objetivo: medir la asociación entre progresión clínica y calidad y duración del sueño en mujeres con cáncer de mama.
