  33. Summary • Either a decrease in sleep duration from a regular 6, 7 or 8h per night or an increase from a regular 7 or 8h per night predict all-cause mortality • A decrease in sleep duration affects all-cause mortality via increases in cardiovascular deaths • An increase in sleep duration affects overall mortality via an increase in non-cardiovascular deaths • Sleep changes over time may represent more reliable measures to assess the impact of sleep on health

  34. Coronary Heart Disease

  36. 1.45 (1.10-1.92) 1.38 (1.03-1.86) Coronary Heart Disease by hours of sleepThe Nurses’ Health Study Women, n=71,617 Hours sleep Ayas NT et al. Arch Intern Med 2003; 163:205-9

  37. Summary • Both short and long sleep duration may be associated with more detrimental effects on cardiovascular health in women than men • The biological mechanisms underlying these associations are unclear • High blood pressure may represent one mechanism linking short sleep duration with increased risk of CHD, at least in women

  38. Unresolved issues • Co-morbidities of sleep disorders (psychiatric/chronic conditions) • Bidirectional relationship (reverse causality/temporality?) • Confounding by other lifestyle behaviors • Sleep as marker of health status vs. risk factor • Biological plausibility • Objective assessment of sleep changes over time

  45. Need for further research… • Objective assessment of sleep changes over time • More prospective evidence • Better understanding of determinants of sleep duration • Better control for confounders/co-morbidities • Experimental evidence on biological plausibility

  46. Low SES/Unhealthy lifestyle/ Poor general health status Co-Morbidities/Elderly Short sleep duration Long sleep duration Appetite dysregulation/ Impaired glucose homeostasis Depression/ Poor general health status Inflammatory/neurovegatative/ hormonal responses CVD/Metabolic alterations Increased morbidity/mortality/ Reduced quality of life Putative pathways
