[Excessive daytime sleepiness. An epidemiological study based on a "sleep/breathing" questionnaire].

Background: A field survey used a "sleep-breathing" questionnaire to estimate the prevalence of the excessive daytime sleepiness in a sample of middle-aged males.

Methods: Eight hundred and fifty men aged 22 to 66 years agreed to answer a questionnaire and have anthropometric measurements. To the question on excessive daytime sleepiness, 90 subjects (10.

[Is a sedentary lifestyle a risk factor for sleep-related respiratory disturbance?].

Introduction: This questionnaire-based epidemiological study was aimed at identifying possible sleep disturbance in a sample of active French males.

Methods: Eight hundred and fifty male subjects, aged 22 to 66 years, completed a structured sleep questionnaire supplemented by information about their life habits and medical history. The study compared the prevalence of positive responses between an "at risk" group of sedentary people (with no declared leisure exercise) and a control group of "exercising" subjects (with more than 5 hours of planned exercise weekly).

Social disparities in musculoskeletal disorders and associated mental malaise: findings from a population-based survey in France.

Aims: Various types of musculoskeletal disorders (MSDs) have comorbid mental disorders, which may in turn have a negative influence on disease course and role impairment, but the contribution of social factors to this type of comorbidity is a much under-researched area. This study investigates whether there is a socially patterned association of MSDs with different dimensions of mental malaise.

Methods: The sample included 3,368 economically active participants aged 18-64 years, randomly selected from the Lorraine region in north-eastern France.

Increase in exhaled nitric oxide is associated with bronchial hyperresponsiveness among apprentices.

Rationale: Airway inflammation is a hallmark of asthma. Several studies have validated the use of the fractional concentration of exhaled nitric oxide (Fe(NO)) as a surrogate marker of airway inflammation in asthma.

Objectives: We examined how the change in Fe(NO) levels, since the beginning of occupational exposure, could be associated with the incidence of bronchial hyperresponsiveness (BHR) among baker, pastry maker, and hairdresser apprentices during their 2-year training.

Early markers of airways inflammation and occupational asthma: rationale, study design and follow-up rates among bakery, pastry and hairdressing apprentices.

Background: Occupational asthma is a common type of asthma caused by a specific agent in the workplace. The basic alteration of occupational asthma is airways inflammation. Although most patients with occupational asthma are mature adults, there is evidence that airways inflammation starts soon after inception of exposure, including during apprenticeship.
