Characteristics of drowning by different age groups

Area of Science:

• Public Health
• Epidemiology
• Injury Prevention

Background:

• Unintentional drowning risk is known to vary with age.
• Drowning episode characteristics by age group are not well-described.
• Understanding these variations is crucial for effective prevention strategies.

Purpose of the Study:

• To describe the characteristics of unintentional drowning incidents across different age groups.
• To identify age-specific patterns in drowning circumstances and outcomes.

Main Methods:

• Retrospective review of drowning victim data from multiple sources (death certificates, medical examiner, pre-hospital, emergency department, hospital records).
• Study conducted in three counties in Western Washington state.
• Analysis included 709 unintentional drowning fatalities among residents from 1980 to 1995.

Main Results:

• Drowning rates varied significantly by age group, with the highest rates observed in ages 0-4 (30.5) and 15-19 (29.9) per million person-years.
• Drowning locations differed by age: nearly equal proportions in pools, bathtubs, and open water for ages 0-4; predominantly open water for ages 5-64; and bathtub and open water for ages 65+.
• Pre-drowning activities and witness status varied by age, with younger children (0-4) most often drowning while bathing and older adolescents (15-19) while swimming or boating. Medical care involvement was highest in the youngest group.

Conclusions:

• The characteristics of unintentional drowning episodes demonstrate substantial variation across age groups.
• Age-specific drowning patterns necessitate the development and implementation of tailored prevention strategies.
• Further research into age-related drowning circumstances can inform targeted public health interventions.
