Summary
Housing characteristics significantly impact asthma triggers. Environmental pollutants in a home's location are strongly linked to asthma, while dwelling and occupancy factors require more research for effective interventions.
Area of Science:
- Environmental Health
- Epidemiology
- Public Health
Background:
- Asthma prevalence is linked to indoor environmental factors.
- Housing characteristics are recognized asthma triggers, yet interventions remain limited.
- A comprehensive review of housing-related asthma triggers is needed.
Purpose of the Study:
- To conduct a scoping review of published evidence on asthma and housing characteristics.
- To identify and categorize housing features associated with asthma onset and exacerbation.
- To develop a framework for understanding housing typologies and their impact on asthma.
Main Methods:
- Scoping review following Arksey and O'Malley's five steps.
- Searched PubMed, Scopus, and Web of Science databases.
- Included 33 studies, iteratively identifying nine housing characteristics across three levels: location, dwelling, and occupancy.
Main Results:
- Identified nine housing characteristics associated with asthma.
- Strongest evidence links asthma to locational features, particularly environmental and air pollutants.
- Associations between dwelling/occupancy features and asthma showed inconsistent results, indicating a need for further research.
Conclusions:
- A housing typologies framework can map and visualize asthma triggers.
- Environmental pollutants represent a significant risk factor for asthma.
- Targeting housing typologies may offer effective asthma intervention strategies by addressing multiple factors concurrently.

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:

2.7K
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 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.
