Summary
Low health literacy significantly impacts asthma knowledge and proper use of metered-dose inhalers (MDIs). Improving literacy is crucial for better asthma management and patient outcomes.
Area of Science:
- Public Health
- Medical Education
- Respiratory Medicine
Background:
- Health literacy is a critical determinant of health outcomes.
- Many patients with asthma struggle with understanding their condition and using prescribed medications effectively.
- Metered-dose inhalers (MDIs) are common asthma medications requiring proper technique for efficacy.
Purpose of the Study:
- To investigate the association between adult literacy levels and asthma knowledge.
- To assess the relationship between literacy and the correct use of metered-dose inhalers (MDIs).
- To identify literacy as a predictor of asthma management skills.
Main Methods:
- A cross-sectional survey was conducted in an urban public hospital's emergency department and asthma clinic.
- 273 patients with asthma exacerbations and 210 patients in routine care were assessed.
- Literacy was measured using the Rapid Estimate of Adult Literacy in Medicine, alongside asthma knowledge and MDI technique assessments.
Main Results:
- A significant portion of patients (87%) read below the high-school level.
- Lower reading levels strongly correlated with reduced asthma knowledge (p < 0.01).
- Inadequate MDI technique was prevalent, particularly among those with the lowest literacy levels (89% vs 48%).
Conclusions:
- Inadequate health literacy is widespread among asthma patients.
- Literacy level is a significant predictor of both asthma knowledge and MDI technique.
- Interventions to improve health literacy may enhance asthma management and patient outcomes.

01:21Health Literacy
Health literacy is an individual's or a community's capacity to comprehend, receive, read, and use relevant healthcare information and services. The World Health Organization (WHO, 2018) defines health literacy as the cognitive and social skills that determine the ability of individuals to gain access to, understand, and use information in ways that promote and maintain good health. As a result, the WHO helps individuals manage long-term health concerns, participate in preventative programs,...
01:29Asthma-I: Introduction
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...

01:28Asthma I: Introduction
Asthma is a chronic inflammatory disorder of the airways characterized by variable airflow obstruction and heightened bronchial responsiveness to a wide range of triggers. The underlying inflammation leads to airway swelling, mucus hypersecretion, and smooth muscle constriction, all of which narrow the airway lumen and impede airflow. Clinically, asthma presents with recurrent episodes of wheezing, shortness of breath, chest tightness, and coughing, symptoms that typically vary in intensity and...
