“…Future studies should studies, 1 and symptom severity was lower than commonly reported. In addition, there was no difference between African Americans and Whites on RLS measures, which agrees with some studies 14,15,31,32 but not all. 11,33 Given that there is a link between sleep problems and health outcomes, we also explored the relationship of sleep with disability.…”

Objective: Assess the relationship of self-reported sleep quality and possible sleep disorders with disability in a racially diverse sample of community-dwelling older adults.Methods: Participants included 943 non-demented older African Americans (n=452) and Whites (n=491) from two cohort studies, the Minority Aging Research Study (MARS) and the Rush Memory and Aging Project (MAP). Participants completed a 32-item questionnaire assessing sleep quality and the possible presence of three sleep disorders (sleep apnea, restless leg syndrome [RLS] and REM behavior disorder [RBD]). Disability was assessed with scales that quantified the ability to perform instrumental activities of daily living (IADL), basic activities of daily living (ADL), and physical mobility activities.Results: More than half of the participants reported impaired sleep quality (51%), or the possible presence of at least one sleep disorder (57%; sleep apnea 44%, RLS 25% and RBD 7%). Sleep quality was rated poorer in African Americans, those with advancing age and fewer years of education (all P<.05). Only sleep apnea risk was associated with age (P<.02). In logistic regression models adjusted for age, sex, years of education, and race, both sleep quality and disorders were associated with disability (sleep quality with mobility disability (P<.001), sleep apnea risk with mobility disability and IADL disability (all P<.001) and RLS symptoms with mobility disability (P<.01).Conclusions: Results indicate that self-assessed impaired sleep is common in old age and is associated with disability.

“…In this latter case, the publications confirm and of two and up to three times in the emergence of sleep problems, such as apnoea, storing and insomnia among smokers (8,10,23) . Another important detail is that these findings were also repeated with samples of adults, pregnant women, adolescents and children (24)(25) .…”

Health indicators associated with poor sleep quality among university students RESUMEN Objetivo: Asociar la calidad del sueño de los universitarios brasileños con los indicadores de salud. Método: Estudio transversal desarrollado con una muestra aleatoria de 662 estudiantes universitarios de Fortaleza, Brasil. Fueron recogidos datos sociodemográficos, indicadores de salud (tabaquismo, alcoholismo, sedentarismo, estado nutritivo y niveles séricos de colesterol) y el Índice de Calidad del Sueño de Pittsburgh mediante un cuestionario autoadministrado. Las muestras sanguí-neas fueron analizadas en un laboratorio clínico y para evaluar la magnitud de las asociaciones se adoptó la Regresión de Poisson. Resultados: En los universitarios que fuman diariamente la ocurrencia de mala calidad del sueño fue superior en su relación con los no fumadores (p<0,001). Sin embargo, la razón de prevalencia fue de aproximadamente 1. Conclusión: Las probabilidades de presentar mala calidad del sueño fueron prácticamente idénticas entre tabaquistas y etilistas. DESCRIPTORES ABSTRACTObjective: to associate the sleep quality of Brazilian undergraduate students with health indicators. Method: A cross-sectional study was developed with a random sample of 662 undergraduate students from Fortaleza, Brazil. The demographic data, Pittsburgh Sleep Quality Index and health data indicators (smoking, alcoholism, sedentary lifestyle, nutritional condition and serum cholesterol) were collected through a self-administered questionnaire. Blood was collected at a clinical laboratory. In order to estimate the size of the associations, a Poisson Regression was used. Results: For students who are daily smokers, the occurrence of poor sleep was higher than in nonsmokers (p<0.001). Prevalence rate values were nevertheless close to 1. Conclusion: The likelihood of poor sleep is almost the same in smokers and in alcoholics.

“…In the current study, we focus specifically on adolescents’ experiences of discrimination as an important type of stressor that can compromise sleep. Many studies that have examined the impact of discrimination on sleep have focused on adult populations, rather than adolescents (e.g., Grandner et al, 2012; Slopen & Williams, 2014; Tomfohr, Pung, Edwards, & Dimsdale, 2012). Of the few studies that have recently focused on discrimination and sleep during adolescence, researchers found that ethnic discrimination was related to poor sleep quality and shorter sleep duration (Huynh & Gillen-O’Neel, 2013; Yip, 2015).…”

Irregular and insufficient sleep place youth at risk for adverse psychological and physical health outcomes. Recent research indicates that discrimination constitutes a type of stressor that interferes with adolescent sleep; however, the mechanisms through which discrimination affects sleep are not well understood. This study examined whether ethnic and non-ethnic (i.e., gender, age, and height/weight) discrimination were associated with adolescents’ sleep duration, variability, and quality, and whether loneliness and perceived stress mediated these associations. An ethnically-diverse sample (42% Latino, 29% European American, 23% Asian) of adolescents (N = 316; Mage = 16.40 years, 57% girls) reported on their experiences of discrimination, perceived stress, and loneliness. Sleep duration and variability were assessed by actigraphy and sleep quality through self-reports. Ethnic discrimination was related to shorter sleep duration and both ethnic and non-ethnic discrimination were associated with worse sleep quality. Loneliness and perceived stress partially mediated the relation between discrimination and sleep quality. Discriminatory experiences can heighten feelings of loneliness and stress, which, in turn, may contribute to diminished sleep quality during adolescence.
