Is Sleep Duration Associated With Obesity In Older Australian Adults?, Christopher A. Magee, Peter Caputi, Don C. Iverson
Is Sleep Duration Associated With Obesity In Older Australian Adults?, Christopher A. Magee, Peter Caputi, Don C. Iverson
Don C. Iverson
Objectives: To investigate the relationship between sleep duration and obesity in older Australian adults. Method: Self-reported health data were collected through the 45 and Up Study. Multinomial logistic regression models were used to test the relationship between sleep duration and body mass index, controlling for a range of demographic and health-related variables. Results: The sample included 45,325 Australian adults aged 55 to 95 years. The regression models demonstrated that short and long sleep were associated with obesity in 55- to 64-year-olds but not in those aged 65 years and above. Discussion: The present results suggest that the relationships between sleep …

A Link Between Chronic Sleep Restriction And Obesity: Methodological Considerations, Christopher Magee, Donald Iverson, Xu-Feng Huang, Peter Caputi

Emerging evidence suggests that chronicsleeprestriction contributes to obesity. Targeting short sleep duration may therefore offer a novel and effective method of preventing and treating obesity. However, this area of research is only in its infancy, and a complete understanding of how chronicsleeprestriction and obesity are linked is currently lacking. The aim of this paper is to briefly review epidemiological evidence for an association between chronicsleeprestriction and obesity in adults, and outline the key methodological limitations of these studies. Particular attention is paid to the methods used to measure sleep and obesity, as well as the need to control for potential …
Sleep Quality, Fatigue And Physical Activity Following A Cancer Diagnosis, Nancy Humpel, Donald Iverson
Sleep Quality, Fatigue And Physical Activity Following A Cancer Diagnosis, Nancy Humpel, Donald Iverson
Don C. Iverson
Research on physical activity for cancer survivors suggests a relationship with improved quality of life. The aim of this study was to explore if there was also a relationship of physical activity with sleep difficulties and fatigue, common effects of cancer and its treatments. Recruitment was by posters and flyers in medical waiting rooms and by letter of invitation. Thirty-two breast and 59 prostate cancer survivors completed the questionnaire. Poor sleep quality was reported by 57.8%. A greater proportion of breast cancer (36.7%) than prostate cancer survivors (15.5%) reported poor sleep latency, and sleep disturbance (48.4% vs. 17.2%). The mean …
An Investigation Of The Dimensionality Of The Pittsburgh Sleep Quality Index In Australian Adults, Christopher Magee, Peter Caputi, Donald Iverson, Xu-Feng Huang
An Investigation Of The Dimensionality Of The Pittsburgh Sleep Quality Index In Australian Adults, Christopher Magee, Peter Caputi, Donald Iverson, Xu-Feng Huang

The Pittsburgh Sleep Quality Index (PSQI) is widely used to assess subjective sleep quality in clinical and non-clinical settings. Although the PSQI is routinely scored to provide a single sleep quality factor, two recent studies suggest that multiple factor scoring methods could be more appropriate. As a consequence, the present study investigated for the dimensionality and factor structure of the PSQI in 364 Australian adults aged 18 to 59 years. The results demonstrate that two factor and three factor scoring models were favored statistically over the single factor model. These results add to recent findings and suggest that scoring the …
Sleep Duration And Obesity In Middle-Aged Australian Adults, Christopher A. Magee, Donald C. Iverson, Peter Caputi
Sleep Duration And Obesity In Middle-Aged Australian Adults, Christopher A. Magee, Donald C. Iverson, Peter Caputi
Don C. Iverson
The present study examined the association between sleep duration and obesity in 40,834 middle-aged Australian adults. Multinomial logistic regression was used to test the relationship between sleep duration and obesity while controlling for important demographic and health covariates; separate models were tested for males and females. Short sleep (i.e., <7 h a night) was found to be independently associated with obesity in males and females. To our knowledge, this is the first study to report an association between short sleep and obesity in Australian adults. Although more research is required, interventions targeting short sleep could aid obesity treatment and prevention.
Examining The Pathways Linking Chronic Sleep Restriction To Obesity, Christopher A. Magee, Xu-Feng Huang, Donald C. Iverson, Peter Caputi
Examining The Pathways Linking Chronic Sleep Restriction To Obesity, Christopher A. Magee, Xu-Feng Huang, Donald C. Iverson, Peter Caputi

A growing number of studies have identified chronic sleep restriction as a potential risk factor for obesity. This could have important implications for how obesity is prevented and managed, but current understanding of the processes linking chronic sleep restriction to obesity is incomplete. In this paper, we examined some of the pathways that could underlie the relationship between chronic sleep restriction and obesity. This involved exploring some of the potential environmental, health, behavioral, and sociodemographic determinants of chronic sleep restriction, which require further investigation in this context. Three pathways that could potentially link chronic sleep restriction to obesity were then …
