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 …

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 …
