Topic: Gut, metabolism and diet

First, sleep problems are associated with accidents and human errors. The commonest cause of premature mortality in adults is cardiovascular disease and a new meta-analysis suggests that both short and long sleep are associated with increased risk of coronary heart disease and stroke.23 So, mechanisms involving cardiovascular risk factors provide potential explanations for the associations between sleep and mortality. First, short and long sleep are associated with an increased prevalence of hypertension.24 Insomnia and obstructive sleep apnoea have also been linked to higher rates of hypertension. Although the findings are complex, there is compelling evidence that sleep restriction in humans is associated with increases in inflammatory markers, with some evidence of bidirectional effects (Figure 3),26,27 and that inflammatory responses are increased in people with obstructive sleep apnoea.28 Results from observational studies additionally show that treatment of sleep disorders reduces levels of inflammatory markers, although evidence from randomized controlled trials remains equivocal.29 Sleep, inflammation, and cardiovascular disease outcomes (from reference26 with permission) Major sleep disorders are more prevalent among the obese. A meta-analysis has suggested an association between short sleep and obesity,30 although prospective evidence is inconsistent.31,32 In the general population an extra 1 h of sleep is associated with a lower body mass index (0.35 U).30 Although this may seem unimportant at the individual level it has greater significance at the population level.33 For example, based on prevalence data from published studies it has been estimated that 3–5% of the overall proportion of obesity in adults could be attributable to short sleep.34 There is an interesting literature linking sleep with the release of hormones and disrupted endocrine function.35 Many cross-sectional studies have also observed associations between short sleep and diabetes. Reference group is those free of the particular sleep problem (from reference36 with permission) Finally, common mental disorders, in particular depression, are the most prevalent conditions associated with problematic sleep. Insomnia may lead to depression, alternately common causes such as heightened arousal could underlie the two disorders.40 A review of studies that simultaneously examined the effects of sleep and depression on cardiometabolic disease showed sleep to be associated with disease in

Published in a peer-reviewed journal, and it is a meta-analysis pooling many studies. Scored zero for sample size and studied in people because the record does not state it. We have no data on journal's citation record, times cited, citations per year, impact for its field and year, cited by studies here, still being cited, senior author's track record, institution's track record and multi-centre collaboration, so those were left out: it earned 41 of the 58 points we could judge it on, which is 71 out of 100.
