Community violence and asthma: A review

Area of Science:

• Environmental Health
• Epidemiology
• Psychosocial Stressors

Background:

• Epidemiologic studies over 20 years show consistent links between violence exposure and asthma.
• Diverse populations and study designs confirm adverse associations between community violence and asthma.
• Recent research highlights the impact of violence as a psychosocial stressor on respiratory health.

Purpose of the Study:

• To review and synthesize epidemiologic evidence on violence exposure and asthma.
• To focus on research from the past 5 years and seminal studies.
• To discuss potential biological and behavioral mechanisms linking violence and asthma.

Main Methods:

• Systematic review of published epidemiologic literature.
• Analysis of studies examining community violence exposure.
• Synthesis of evidence on direct and indirect effects of violence on asthma.

Main Results:

• Consistent evidence demonstrates a significant association between violence exposure and asthma incidence/exacerbation.
• Research highlights stress-related, behavioral, and epigenetic pathways.
• Violence exposure may increase susceptibility to environmental triggers like air pollution.

Conclusions:

• Violence exposure is a significant environmental risk factor for asthma.
• Understanding mechanisms is crucial for developing targeted interventions.
• Clinical strategies should address psychosocial stressors in asthma management.
