Insights into asthma prevalence in Oregon
1Division of General Internal Medicine, School of Public Health and Preventive Medicine, Oregon Health Sciences University, Portland, USA.
Summary
Oregon
Area of Science:
- Public Health
- Epidemiology
- Chronic Disease Management
Background:
- Asthma is a prevalent chronic disease with increasing rates.
- Oregon's asthma mortality rate is notably higher than the national average.
- Systematic assessment of asthma's prevalence and impact in Oregon is lacking.
Purpose of the Study:
- To estimate current and lifetime asthma prevalence in Oregon.
- To investigate factors contributing to Oregon's elevated asthma mortality rate.
Main Methods:
- Utilized statewide hospital discharge data.
- Incorporated data from the 1995 Behavioral Risk Factor Surveillance Survey.
- Analyzed school registration data from the Portland area.
Main Results:
- Estimated current asthma prevalence at 6-7% and lifetime prevalence at 6-11% for Oregon adults and children.
- Observed an increase in asthma prevalence during adolescence.
- Found no higher hospital discharge rates in the Willamette Valley despite high pollen counts.
Conclusions:
- Oregon's asthma prevalence is significant, particularly increasing in adolescents.
- Higher reported asthma mortality may be linked to accurate death certificate reporting and demographic factors.
- Further investigation into asthma management and environmental triggers in Oregon is warranted.

01:20Asthma: Pathogenesis and Management
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.

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...
01:26Asthma-II: Pathophysiology and Classification
Asthma is a prevalent chronic respiratory condition marked by inflammation and hyperresponsiveness of the airways. Its pathophysiology involves complex interactions among inflammatory pathways, immune responses, and neural mechanisms.
Additionally, environmental and genetic factors play crucial roles in determining an individual's susceptibility to asthma and the severity of their condition.
Critical processes in asthma pathophysiology include:

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...
01:13Asthma III: Clinical Manifestations
Asthma presents with a characteristic pattern of episodic respiratory symptoms that reflect underlying airway inflammation, bronchoconstriction, and mucus hypersecretion. Although severity varies among individuals, certain clinical manifestations are considered hallmarks of the disorder and often guide diagnosis and assessment.Respiratory SymptomsA persistent cough is one of the most common early features of asthma. It is frequently dry and tends to worsen at night or in the early morning,...
