Qualidade de sono em universitários de uma instituição privada / Sleep quality in universities in a private institution

O sono é uma suspensão normal e temporária do nível de consciência, fazendo parte do ciclo sono vigília, sendo regulado por um componente circadiano. Os universitários estão propensos a obter distúrbios do sono devido ao estilo de vida e fatores ambientais. OBJETIVO: Investigar a qualidade de sono, presença de sonolência diurna excessiva e fatores associados em estudantes do curso de fisioterapia de uma faculdade privada. METODOLOGIA: Tratase de um estudo de campo de caráter transversal, quantitativo onde os voluntários foram avaliados através do Índice de Qualidade de Sono de Pittsburgh (PSQI) e escala de sonolência de Epworth. Foram incluídos alunos do curso de fisioterapia e excluídos aqueles não preencheram completamente os instrumentos e aqueles que tomaram medicamentos que afetam o sono. Para a análise estatística, foi utilizado um intervalo de confiança de 95% e nível de significância de 5% (p ≤ 0,05). RESULTADOS: Foram 80 estudantes, 71,3% eram do sexo feminino, 80% eram solteiros e do turno da manhã, 63,5% não trabalhavam, 46,3% praticavam atividade física. Quanto à qualidade de sono, observou-se média do escore do PSQI de 9,5 ± 3,6, com predomínio de má qualidade de sono nos estudantes com 82,5%. Em relação à presença de sonolência diurna excessiva (SED) nos estudantes observou-se média de escore da escala de Epworth de 11,2 ± 4,5, com 55% dos estudantes apresentando SED. Não houve diferença entre os escores de PSQI e Epworth entre os períodos do curso, turno de estudo e estudantes trabalhadores. CONCLUSÃO: Houve maior prevalência de alunos com sono ruim, onde a sonolência diurna excessiva foi destacada na maioria. A má qualidade de sono atingiu aos estudantes sem diferenciação entre períodos do curso, turno de estudo e trabalho.

Sleep is a normal and temporary suspension of the level of consciousness, being part of the sleep-wake cycle, being regulated by a circadian component. College students are likely to get sleep disorders due to lifestyle and environmental factors. OBJECTIVE: To investigate the quality of sleep, the presence of excessive daytime sleepiness and associated factors in students of the physiotherapy course at a private college. METHODOLOGY: This is a cross-sectional, quantitative field study where volunteers were assessed using the Pittsburgh Sleep Quality Index (PSQI) and Epworth sleepiness scale. Physiotherapy students were included and those who did not completely fill out the instruments and those who took medications that affect sleep were excluded. For the statistical analysis, a 95% confidence interval and a significance level of 5% (p ≤ 0.05) were used. RESULTS: There were 80 students, 71.3% were female, 80% were single and in the morning shift, 63.5% did not work, 46.3% practiced physical activity. As for sleep quality, a mean PSQI score of 9.5 ± 3.6 was observed, with a predominance of poor sleep quality in students with 82.5%. Regarding the presence of excessive daytime sleepiness (SED) in students, an average Epworth scale score of 11.2 ± 4.5 was observed, with 55% of students presenting EDS. There was no difference between the PSQI and Epworth scores between the periods of the course, study shift and working students. CONCLUSION: There was a higher prevalence of students with poor sleep, where excessive daytime sleepiness was highlighted in the majority. The poor quality of sleep reached students without differentiating between periods of the course, study shift and work.

EFFECTS OF HABITUAL EXERCISE ON SLEEP HABITS AND SLEEP HEALTH IN MIDDLE-AGED AND OLDER JAPANESE WOMEN / 体力科学

The present study performed a cross-sectional survey to investigate sleep habits and sleep health in Japanese women aged 40 to 69 years with and without a habit of exercise. A standardized questionnaire evaluating sleep was administered to two subject groups. One was the “exercise group” who habitually performed aerobic exercise at mild to moderate intensity with a frequency of ≥2 times/week and duration of ≥30 minutes/one session (n=207) . The other was the age-matched “non-exercise group” who had no exercise habit (n=567) . Two-way ANOVA was employed for com paring the two subject groups and examining the effects of exercise on aging. Regarding sleep habits, as bed time significantly advanced with advancing age, sleep habits (bed time, waking time and sleep duration) were significantly more regular in the exercise group than in the non-exercise group. Concerning independent sleep health risk factors consisting of sleep initiation, sleep maintenance, sleep apnea, parasomnia, and waking-up, the factor score for sleep maintenance significantly deteriorated with advancing age; and was significantly better in the exercise group than in the non-exercise group. These results suggest that an exercise habit may improve sleep health in middle-aged and older Japanese women among which a higher prevalence of sleep problems has been reported.
