“…These findings are consistent with those reported by Krueger and Friedman (2009) (see Table 4), and are supportive of several smaller scale and less comprehensive studies (Wetter and Young, 1994, Patel et al, 2006a, Patel et al, 2006b, Ferrie et al, 2007, Nunes et al, 2008, Stranges et al, 2008and Krueger and Friedman, 2009). …”

“…Our results demonstrate that 16.6% of participants reported short sleep (< 7 h sleep a night), which is similar to a recent study of 3300 Australian adults (Bartlett et al, 2008), and 13.9% reported long sleep (≥ 9 h sleep a night). Previous studies conducted in the US (Kripke et al, 2002, Hale and Do, 2007, Gangwisch et al, 2008, Nunes et al, 2008and Krueger and Friedman, 2009, Europe (Ursin et al, 2005 andFerrie et al, 2007) and Asia (Shankar et al, 2008) have indicated that short and long sleep were common in adults. Although we observed a similar pattern, the precise figures for short sleep (16.6% vs.…”

“…These findings are concerning because short sleep is increasingly common and is currently reported by approximately 30% of US adults (Kripke et al, 1979, Kripke et al, 2002, Nunes et al, 2008and Krueger and Friedman, 2009). Long sleep (≥ 9 h sleep a night) has also been associated with increased morbidity and mortality in adult populations (Tamakoshi and Ohno, 2004, Ferrie et al, 2007, Hublin et al, 2007and Shankar et al, 2008.…”

Objective: Short (< 7 h) and long sleep durations (≥ 9 h) have recently been linked with increased mortality in the US, Europe and Asia, but little is known about the sleep patterns of Australian adults. The present study examined the sleep habits of Australian adults and identified socio-demographic and health-related factors associated with short and long sleep. Methods: This study analyzed cross-sectional and self-reported data from 49,405 Australian adults aged 45 to 65 years collected between 2006 and 2008. Socio-demographic and health-related factors were entered into multinomial logistic regression models predicting self-reported sleep duration. Results: Short and long sleep were reported by 16.6% and 13.9% of participants respectively. Short sleep was associated with long working hours (odds ratio [OR] = 1.17, 95% confidence interval (CI): 1.08, 1.28) and obesity (OR = 1.29, 95% CI: 1.19, 1.41); long sleep was associated with recent treatment for cancer (OR = 1.64, 95% CI: 1.34, 2.02) and heart attack/angina (OR = 1.58, 95% CI: 1.19, 2.09). Conclusions: Short and long sleep were common in this sample of middle aged Australian adults. The determinants of short sleep have potential public health implications and could be targeted to prevent morbidity and mortality associated with short sleep. confidence interval (CI): 1.08, 1.28) and obesity (OR = 1.29, 95% CI: 1.19, 1.41); long sleep was associated with recent treatment for cancer (OR = 1.64, 95% CI: 1.34, 2.02) and heart attack/angina (OR = 1.58, 95% CI: 1.19, 2.09).

Objective: To examine the relationship between measures of sleep quality and the presence of commonly encountered comorbid and sociodemographic conditions in elderly Black subjects. Method: Analyses included participants from the Baltimore Study of Black Aging (BSBA; n = 450; mean age 71.43 years; SD 9.21). Pittsburgh Sleep Quality Index (PSQI) measured overall sleep pattern and quality. Self-reported and objective measures of physical and mental health data and demographic information were collected for all participants. Results: Sociodemographic and comorbid health factors were signifi cantly associated with sleep quality. Results from regression analyses revealed that older age, current fi nancial strain, interpersonal problems, and stress were unique predictors of worse sleep quality. Sleep duration was signifi cantly correlated with age, depressive affect, interpersonal problems, and stress; only age was a unique signifi cant predictor. While participants 62 years or younger had worse sleep quality with increasing levels of stress, there was no signifi cant relationship between sleep quality and stress for participants 81 years and older. Conclusions: Several potential mechanisms may explain poor sleep in urban, community dwelling Blacks. Perceived stressors, including current fi nancial hardship or hardship experienced for an extended time period throughout the lifespan, may infl uence sleep later in life.

Study Objectives To examine the association between substance use and short sleep duration in individuals with schizophrenia or schizoaffective disorder, depressive type (SADD). Design Cross‐sectional, retrospective study. Setting Urban, suburban, and rural centers across the United States. Participants 2,462 consented, adult individuals with schizophrenia or schizoaffective disorder, depressive type (SADD). Participants included inpatients in acute or chronic care settings as well as outpatients and residents in community dwellings. Measurements Substance use was assessed with 10 questions adopted from well‐validated measures (e.g., CAGE questionnaire) for alcohol, marijuana, and illicit drugs. Short sleep duration was defined as <6 hr of self‐reported sleep per night. Results Close to 100% of our sample used nicotine while 83% used substances other than nicotine. More importantly, there was a significant association between substance use and short sleep duration. Interestingly, this association was strongest among African–Americans with schizophrenia or SADD. Conclusions Because psychiatric medications often target chemical receptors involved with both sleep and substance use, understanding the association between short sleep duration and substance use in individuals with schizophrenia and SADD is important. Given that the majority of premature deaths in individuals with psychotic illness are due to medical conditions associated with modifiable risk factors, prospective studies designed to examine the effect of short sleep duration on behaviors like substance use should be undertaken. Finally, analyzing genetic and environmental data in a future study might help illuminate the strong association found between short sleep duration and substance use in African–Americans with schizophrenia and SADD. © 2015 Wiley Periodicals, Inc.
