Insights
Young children with younger siblings face a higher risk of accidental injuries. Parents need to provide extra attention to these children to prevent injuries.
Area of Science:
- Pediatrics
- Public Health
- Epidemiology
Context:
- Accidental injuries are a significant concern for child safety.
- Understanding risk factors is crucial for prevention strategies.
- This study focuses on preschool-aged children (4-5 years) in southern Brazil.
Purpose:
- To identify key risk factors associated with accidental injuries in 4-5-year-old children.
- To analyze the relationship between various demographic, socioeconomic, and environmental factors and injury occurrence.
Summary:
- A prospective cohort study involving 4-5-year-old children in southern Brazil found that 53.8% experienced accidents, with 48.4% sustaining injuries monthly.
- Boys and white children showed higher injury rates.
- Key risk factors identified include the presence of younger siblings (30% increase) and living in brick homes (35% increase).
- Children in day-care centers and periurban areas also showed higher incidence.
Impact:
- Findings highlight that the presence of younger siblings is a modifiable risk factor for childhood injuries.
- Results emphasize the need for increased parental awareness and supervision when younger siblings are present.
- The study contributes to developing targeted injury prevention programs for young children.
Objective:
To measure the main risk factors associated with the occurrence of accidental injuries in children aged 4-5 years.
Methods:
The study included a prospective cohort of children whose parents filled in a diary recording accidents and injuries during a period of one-month. The children represented a systematic subsample from a population-based birth cohort in southern Brazil. The outcome was the number of reported injuries per child during one month. Multivariate analysis (Poisson regression) was used to assess confounding factors.
Results:
The monthly frequency of accidents was 53.8%, and 48.4% of the children suffered at least one injury. Boys had 30% more injuries than girls, and white children had 70% higher incidence than non-white. Family income, parental education and maternal employment were not associated with the frequency of injuries. After adjustment of socioeconomic and environmental factors, having younger siblings was associated with a 30% higher injury rate, and living in a home made of bricks was associated with a 35% increase. The incidence of injuries appeared to be higher among children attending day-care centers and those living in periurban areas.
Conclusions:
Few risk factors were associated with an increased frequency of injuries. Among them, the most amenable to intervention seems to be the presence of younger siblings. Parents should become aware of children's needs for increased attention when a younger sibling is born.
