Prevalence of insomnia and its clinical correlates in a general population in Turkey

Abstract

Aim The prevalence of insomnia is influenced by environmental factors. This study aimed to investigate the prevalence of insomnia and its sociodemographic and clinical correlates in a general population‐based survey in Turkey. Methods This population‐based study included 4758 subjects among 5021 who participated in the Turkish Adult Population Epidemiology of Sleep Disorders study. Questionnaire items evaluating insomnia were adapted from the International Classification of Sleep Disorders II and the DSM‐IV‐TR. Subjects with restless legs syndrome were excluded. Results Insomnia was found to be associated with older age (18–24 years, 9.8%; 25–44 years, 11.7%; 45–64 years, 13.8%; 65 years or older, 13.9%), lower income level (<500 USD, 16.5%), time spent watching TV (6–8 h or more, 18.4%), tea consumption in the evening (≥6 glasses, 14.5%) and smoking status (current and ex‐smoker, both 14.2%) in multiple logistic regression analysis. In respect to other medical disorders, insomnia was significantly associated with the presence of hypertension, diabetes and heart diseases after the adjustment for relevant risk factors for each disease, across all age and sex groups. Conclusions Insomnia is a major health problem in our population, affecting subjects in the working age group and those of lower socioeconomic status. It should especially be screened in patients with chronic diseases. A relatively low proportion of insomnia diagnosed as a sleep disorder suggests that this condition and its clinical correlates are possibly under‐recognized.

The Relationship of Stroke and Sleep-A Review

“…Dünya çapında yapılan çeşitli çalışmalar, popülasyonun %10-30, bazıları ise %50-60 kadarında insomni olduğunu göstermiştir. Yetişkinlerde, kadınlarda ve eşlik eden fiziksel veya ruhsal hastalığı olanlarda daha yaygındır (59)(60)(61) (62). Toplum Ateroskleroz Riski çalışmasından elde edilen veriler; insomninin, artmış Koroner Kalp hastalığı, miyokard enfarktüsü veya ölüm riski ile ilişkili olduğunu saptamıştır.…”

An under-diagnosed geriatric syndrome: sleep disorders among older adults

“…Benbir et al analyzed a total of 5021 people in their study of the Turkish adult population epidemiology of sleep disorders (TAPES). The authors demonstrated that the incidence of insomnia among the elderly (aged 65 years and older) was 13.9% 28 . Overall, difficulty in falling asleep was reported to be experienced by 15-45% of the elderly, interrupted sleep by 20-65%, waking up exceptionally early by 15-54%,and inability to wake up rested was 10% [29][30] .…”

A Relationship between Periodic Limb Movements in Sleep and High Nocturnal Blood Pressure Values in Patients with Insomnia

“…Insomnia, which is the most common sleep disorder with a prevalence ranging from 3.4% to 19.1%, depending on the diagnostic criteria and population studied, [1][2][3][4] is a significant public health burden. Moreover, a number of recent studies have found a relationship between insomnia and the prevalence of hypertension.…”
