Asthma-I: Introduction01:29

Asthma-I: Introduction

3.7K
Asthma is a chronic respiratory ailment that requires careful management due to its varying symptoms and influencing factors. It is characterized by airway inflammation, bronchial hyperresponsiveness, and reversible airflow obstruction, leading to symptoms like wheezing, shortness of breath, chest tightness, and coughing. The symptom frequency and intensity may vary considerably over time. It is also linked to immune system responses to allergens and irritants, highlighting the complex...

Asthma: Pathogenesis and Management

1.7K
Asthma is a chronic pulmonary condition involving inflammation of the airways, hyper-reactivity, and reversible obstruction of the airways. This condition can significantly impact a person's quality of life, making breathing difficult and leading to distressing symptoms.
Asthma is classified as allergic and non-allergic. Allergens such as dust mites, pollen, and pet dander trigger allergic asthma, while factors like cold air, intense emotions, or exercise can induce non-allergic asthma.

    Area of Science:

    • Occupational Health
    • Epidemiology
    • Public Health

    Background:

    • Work-related asthma (WRA) is a significant occupational disease with severe health consequences.
    • Previous estimates (2006-2009) indicated 9.0% of adults with current asthma had WRA.

    Purpose of the Study:

    • To provide updated national and state-specific prevalence estimates for WRA.
    • To establish a new baseline following changes in survey methodology and WRA questions.

    Main Methods:

    • Analysis of 2012 Behavioral Risk Factor Surveillance System (BRFSS) and Adult Asthma Call-back Survey (ACBS) data from 22 states.
    • Inclusion of both landline and cellular telephone samples with updated weighting methodology and revised WRA questions.

    Main Results:

    • In 2012, 9.0% of adults had current asthma.
    • Among those with current asthma, 15.7% had WRA, with state-specific rates ranging from 9.0% to 23.1%.
    • WRA prevalence was highest in the 45-64 age group (20.7%).

    Conclusions:

    • Updated estimates provide a crucial baseline for WRA prevalence post-methodology changes.
    • Findings will aid targeted interventions to reduce the burden of WRA.
    • Data supports public health initiatives for prevention and control of occupational asthma.
