The National Comission on Sleep Disorder Research evaluated the status of insomnia and other sleep disorders in the US. The Commission found that insomnia is prevalent affecting 20-30 million Americans, has significant morbidity especially related to attention and memory processes and cost the US an estimated $ 15 billion a year. It also estimated that all of these figures should rise significantly by the year 2000. Other sleep disorders (eg, narcolepsy and sleep apnea) although less prevalent have significant costs to patients and society associated with them. The Commission recommended that the US develop a research and education program to develop new insights into the basic mechanisms of sleep disorder. The education program needs to be directed to the general public; medical practitioners, as well as patients.

Sleep complaints and disorders are frequent in geriatric patients, with a prevalence of 57%. They result in increased morbidity and mortality. In this population, the primary goal is to search for a cause of secondary insomnia, such as organic or psychiatric diseases, or medications. In those cases, sleep will improve with the treatment of the cause. In the cases of primary insomnia, behavioral and sleep hygiene therapy are essential. Hypnotics have frequent side effects and should be avoided when possible. Prescription of small doses of benzodiazepines or related drugs should only be for a short period of time. Molecules with a short half life are to be preferred. Other sleep disorders include sleep apnea syndrome, restless legs syndrome and periodic limb movements, which are the most frequent diagnoses in an elderly population. In the restless legs syndrome, diagnostic workup must include the search for a cause and treatment should favor hygienic measures. The use of dopamine agonists must be cautious, as their tolerance is poor in the elderly. Periodic limb movements are also frequent but there is no particular therapeutic recommendation.

The circadian system is known to play a role in glucose metabolism. Chronotype reflects the interindividual variability in the phase of entrainment. Those with later chronotype typically prefer later times in the day for different activities such as sleep or meals. Later chronotype has been shown to be associated with metabolic syndrome, increased diabetes risk and poorer glycemic control in type 2 diabetes patients. In addition, "social jetlag", a form of circadian misalignment due to a mismatch between social rhythms and the circadian clock, has been shown to be associated with insulin resistance. Other sleep disturbances (insufficient sleep, poor sleep quality and sleep apnea) have also been shown to affect glucose metabolism. In this study, we explored whether there was a relationship between chronotype, social jetlag and hemoglobin A1c (HbA1c) levels in prediabetes patients, independent of other sleep disturbances. A cross-sectional study was conducted at the Department of Family Medicine, Ramathibodi Hospital, Bangkok, from October 2014 to March 2016 in 1014 non-shift working adults with prediabetes. Mid-sleep time on free day adjusted for sleep debt (MSFsc) was used as an indicator of chronotype. Social jetlag was calculated based on the absolute difference between mid-sleep time on weekdays and weekends. The most recent HbA1c values and lipid levels were retrieved from clinical laboratory databases. Univariate analyses revealed that later MSFsc (p = 0.028) but not social jetlag (p = 0.48) was significantly associated with higher HbA1c levels. Multivariate linear regression analysis was applied to determine whether an independent association between MSFsc and HbA1c level existed. After adjusting for age, sex, alcohol use, body mass index (BMI), social jetlag, sleep duration, sleep quality and sleep apnea risk, later MSFsc was significantly associated with higher HbA1c level (B = 0.019, 95% CI: 0.00001, 0.038, p = 0.049). The effect size of one hour later MSFsc on HbA1c (standardized coefficient = 0.065) was approximately 74% of that of the effect of one unit (kg/m2) increase in BMI (standardized coefficient = 0.087). In summary, later chronotype is associated with higher HbA1c levels in patients with prediabetes, independent of social jetlag and other sleep disturbances. Further research regarding the potential role of chronotype in diabetes prevention should be explored.
