Obstructive ventilatory impairment. An investigation in general practice.

J G Hansen, H Schmidt

    Scandinavian Journal of Primary Health Care
    |December 1, 1991
    PubMed
    Summary

    Obstructive ventilatory impairment is common, affecting 26% of adults based on MMEF values. This lung condition is linked to older age, chronic bronchitis, asthma, and smoking.

    Area of Science:

    • Pulmonary Medicine
    • Epidemiology
    • Public Health

    Background:

    • Obstructive ventilatory impairment is a significant public health concern.
    • Understanding its prevalence and risk factors is crucial for early detection and management.

    Purpose of the Study:

    • To estimate the prevalence of obstructive ventilatory impairment in a general practice population.
    • To investigate the relationship between obstruction and factors like age, sex, chronic bronchitis, asthma, and smoking.

    Main Methods:

    • A cross-sectional epidemiological study was conducted.
    • Dynamic spirometry (Vitalograph) was performed on 2740 individuals aged 16 years and older.
    • Data analysis focused on prevalence rates and correlations with various demographic and clinical factors.

    Main Results:

    • A high prevalence of obstruction was observed: 26% had MMEF < 75%, 8% had FEV-1 < 75%, and 5% had FEV-1/FVC < 65%.
    • Obstruction showed significant correlations with older age, chronic bronchitis, asthma, and smoking.
    • No significant correlation was found with sex.

    Conclusions:

    • Obstructive ventilatory impairment is prevalent in the general population studied.
    • Older age, chronic bronchitis, asthma, and smoking are significant risk factors for obstruction.
    • These findings highlight the importance of screening and targeted interventions for at-risk individuals.
