Cognitive behavioural therapy interventions for insomnia among shift workers: RCT in an occupational health setting
2019
Abstract Introduction The aim of the study was to compare the effectiveness of cognitive behavioural therapy interventions for insomnia (CBT-I) to that of a sleep hygiene intervention in a randomized controlled design among shift workers. We also studied whether the features of shift work disorder (SWD) affected the results. Methods A total of 83 shift workers with insomnia disorder were partially randomized into a group-based CBT-I, self-help CBT-I, or sleep hygiene control intervention. The outcomes were assessed before and after the interventions and at 6-month follow-up using questionnaires, a sleep diary, and actigraphy. Results Perceived severity of insomnia, sleep-related dysfunction…
Papel del sueño en el desarrollo de obesidad infantil
2021
El sobrepeso y la obesidad infantil suponen uno de los mayores problemas de salud a nivel mundial, incrementándose su incidencia en las últimas décadas. Esto acarrea la aparición de diversos problemas en el desarrollo, así como de varias patologías comórbidas durante la edad adulta, empeorando la calidad de vida y comportando un gran gasto económico para los sistemas nacionales de salud. La obesidad generalmente se ha visto asociada a la adopción de hábitos dietéticos no saludables y a una reducción de la actividad física diaria, derivada de un aumento del sedentarismo. No obstante, las terapias asociadas a la mejora de este estilo de vida no han resultado tener el éxito esperado. Ahora bie…
Physiological and autonomic stress responses after prolonged sleep restriction and subsequent recovery sleep in healthy young men
2018
Purpose Sleep restriction is increasingly common and associated with the development of health problems. We investigated how the neuroendocrine stress systems respond to prolonged sleep restriction and subsequent recovery sleep in healthy young men. Methods After two baseline (BL) nights of 8 h time in bed (TIB), TIB was restricted to 4 h per night for five nights (sleep restriction, SR, n = 15), followed by three recovery nights (REC) of 8 h TIB, representing a busy workweek and a recovery weekend. The control group (n = 8) had 8 h TIB throughout the experiment. A variety of autonomic cardiovascular parameters, together with salivary neuropeptide Y (NPY) and cortisol levels, were assessed.…
