Prevalence of chronic obstructive respiratory diseases amongst fishermen
Abstract
Background: The objective was to screen and evaluate the prevalence of respiratory diseases and obstructive ventilatory defects among fishermen in Morocco.
Materials and methods: This observational and cross-sectional epidemiological study involved 924 men over 20 years old and with at least two years of seniority. It included a questionnaire and a spirometry. The questionnaire is composed of four sections: sociodemographic and occupational characteristics, toxic habits, medical history and respiratory clinical symptoms.
Results: The prevalence of symptoms of tracheobronchial irritation was 9.2% for cough, 8.2% for sputum 7.8% for dyspnoea and chest wheezing 8.1%. The frequency of rhinitis was 17.1%, asthma 6.8%, chronic bronchitis 5.6% and chronic obstructive pulmonary disease (COPD) 4.1% (5.4% for current and former smokers versus 1.1% for non-smokers). The prevalence was reaching 6.8% among those who smoked more than 10 pack-years and 17.9% among those who smoked more than 20 pack-years. Among subjects over 40 years old who had smoked more than 10 pack-years, the prevalence of COPD was 8.1%. The comorbidities were frequent.
Conclusions: Smoking was very common among fishermen. Symptoms and respiratory diseases remain underdiagnosed and undertreated. Prevention and early detection must be a priority in this sector.
