Individuals with asthma report worse self-rated health (SRH) compared to those without the condition. This simple SRH measure is valuable for identifying asthma patients needing additional support.
Area of Science:
- Public Health
- Epidemiology
- Health Services Research
Background:
- Self-rated health (SRH) predicts health outcomes, with poor SRH linked to increased inflammation.
- Asthma, a chronic inflammatory disease with systemic effects, warrants investigation into its relationship with SRH.
Purpose of the Study:
- To compare self-rated health (SRH) between individuals with and without current asthma.
- To compare SRH with quality-of-life (QoL) ratings in individuals with and without asthma.
Main Methods:
- A 1995 survey of 5355 adults in Stockholm County, Sweden, randomly selected from the general population.
- Respondents were categorized by current asthma status, sex, and age group (18-44 and ≥45 years).
- SRH was assessed using a single-item general health status question; QoL was measured using the Gothenburg Quality of Life Instrument and Ladder of Life.
Main Results:
- Individuals with asthma reported significantly poorer SRH than those without, with an exception for women aged 18-44.
- SRH demonstrated an association with asthma comparable in strength to QoL measures.
- SRH offers a simpler application compared to comprehensive QoL instruments.
Conclusions:
- SRH is an easily obtainable health metric.
- SRH provides a valuable dimension of health status.
- SRH can complement existing tools to identify asthma patients requiring enhanced management and support.

Additionally, environmental and genetic factors play crucial roles in determining an individual's susceptibility to asthma and the severity of their condition.

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.
