Sleep is usually considered as a factor for good health and personal equilibrium. However, the epidemiology of insomnia, which is the most frequent of sleep disorders, is still unknown in France.
All epidemiological studies concerning the prevalence of insomnia and its associated factors carried out in France and published between 1980 and 2009 have been extracted from Medline. Subsequently, a research of reports not indexed in Medline has been carried out in the national Public health Database. We also sought the presence of questions concerning sleep disorders in questionnaires and reports from health surveys in the general population.
In the general population, six specific studies had been undertaken between 1987 and 2003 while there had been eight occupational studies between 1980 and 2000. Surveys in schoolchildren and in students focused on the daytime tiredness due to lack of sleep but few studies investigated insomnia in children and teenagers. Methodological differences as well as the heterogeneity in the definition of the disorders yielded very diverse prevalences. Between 30 and 50% of adults in France declared the presence of at least one sleep disorder while the prevalence of insomnia using the DSM-IV criteria concerned between 15 and 20% of the population. Women reported sleep disorders more frequently than men. Sleep disorders were associated with work absenteeism. Comorbidity with anxiety and depressive disorders has also been highlighted in several studies.
Surveillance of sleep disorders appears as an important public health issue requiring prior standardization of questionnaires and survey methods.

    ABSTRACT: [Purpose] Insomnia is quite common and it can affect the quality of life of an individual. Students undergo stress due to various academic demands leading to sleeplessness and daytime sleepiness. This study was conducted to investigate the association between physical activity and insomnia among female Saudi students. [Subjects] 62 female students with a mean age of 21 ± 1.5 years took part in a motivational program to increase the number of steps taken per day for three weeks. [Methods] After obtaining subject's informed consent all the subjects were assessed for insomnia using the insomnia severity index (ISI), They were then given pedometers to calculate the number of steps they took per day. A physical activity log was kept for three weeks. Pre- and post -intervention ISI scores were calculated and correlated with the 3-week physical activity log. [Results] 50% of the subjects had no clinically significant insomnia (NCSI), 42% had sub threshold (STI), and 8% had moderate clinical (MCI) insomnia. There was a moderate negative correlation between physical activity and ISI scores after the 3-week motivation program. [Conclusion] Prevalence of insomnia was common among female Saudi students and increase in physical activity appears to improve the sleep pattern.

    • "This study’s most prevalent sleep diagnosis was chronic insomnia, followed by circadian rhythm sleep disorders. The prevalence of insomnia in the general population is 15-20% [45] and prevalence of circadian rhythm sleep disorders ranges from 3.1% in adults aged 40–64 to 16% in adolescents [46]. Our prevalence of 42.6% insomnia and 20.1% CRSD is only partially comparable based on our group’s pre-selection criteria (RTx recipients having poor SQ and/or DS). "

    ABSTRACT: Poor sleep quality (SQ) and daytime sleepiness (DS) are common in renal transplant (RTx) recipients; however, related data are rare. This study describes the prevalence and frequency of self-reported sleep disturbances in RTx recipients. This cross-sectional study included 249 RTx recipients transplanted at three Swiss transplant centers. All had reported poor SQ and / or DS in a previous study. With the Survey of Sleep (SOS) self-report questionnaire, we screened for sleep and health habits, sleep history, main sleep problems and sleep-related disturbances. To determine a basis for preliminary sleep diagnoses according to the International Classification of Sleep Disorders (ICSD), 164 subjects were interviewed (48 in person, 116 via telephone and 85 refused). Descriptive statistics were used to analyze the data and to determine the frequencies and prevalences of specific sleep disorders. The sample had a mean age of 59.1 +/- 11.6 years (60.2% male); mean time since Tx was 11.1 +/- 7.0 years. The most frequent sleep problem was difficulty staying asleep (49.4%), followed by problems falling asleep (32.1%). The most prevalent sleep disturbance was the need to urinate (62.9%), and 27% reported reduced daytime functionality. Interview data showed that most suffered from the first ICSD category: insomnias. Though often disregarded in RTx recipients, sleep is an essential factor of wellbeing. Our findings show high prevalences and incidences of insomnias, with negative impacts on daytime functionality. This indicates a need for further research on the clinical consequences of sleep disturbances and the benefits of insomnia treatment in RTx recipients.

    ABSTRACT: Objectives. To investigate the six-week influence of acupuncture on sleep quality and daytime functioning in primary insomnia. Methods. The study was a double-dummy, single-blinded, randomized, placebo-controlled clinical trial. A total of 180 patients with primary insomnia were randomly assigned to 3 groups: verum group underwent verum acupuncture plus placebo; estazolam group underwent estazolam plus sham acupuncture; sham group underwent sham acupuncture plus placebo. The outcome was measured by Pittsburgh Sleep Quality Index (PSQI), Epworth Sleepiness Scale (ESS), and the 36-item short-form health survey (SF-36). Results. The three groups showed significant improvement compared with the pretreatment baseline. Compared with the other two groups, the verum group reported improved sleep quality (SQ) and vitality (VT), decreased daytime dysfunction (DD) and sleepiness (ESS score). The differences were kept from the treatment period to the end of the trial. Discussion. Verum acupuncture appeared to be more effective in increasing sleep quality and daytime functioning than sham acupuncture and estazolam. Trial Registration. The trial is registeded with ISRCTN12585433.
