Abstract

The aim of this study was to determine whether the socioeconomic status (SES) of parents influences early childhood unintentional injury deaths for different injury mechanisms and the gender and age at death of the child. Study design is a population-based retrospective study. Death certificate data from 1995 to 2004 were linked to birth certificate data from 1995 to 1996 for each child who died when aged < or = 8 years. Parental age, birth order, marital status, residence area, educational level, and occupation were used as indices for SES. Cox proportional-hazards analysis was employed. Our results indicate that nonmetropolitan residence, low parental education level, and a father working in a nonadministrative job or as a farmer were associated with a higher risk of death from injury for both boys and girls. A mother aged younger than 20 years and parents working in manual jobs were associated with a higher risk in boys only. The risks of some socioeconomic factors (low parental education and a father working in a manual job or as a farmer) were evident for children aged 1-4 years. The risks of rural residency tended to increase in older children, and the risk of injury from having a mother aged younger than 20 years increased for younger children. The risks of childhood injury deaths from traffic accidents, falls, and fire/burns were associated with the SES of the parents. Younger parents were associated with higher risks of injury deaths from traffic accidents (hazard ratio [HR]: father, 7.9; mother, 1.9) and falls (HR: father, 2.0; mother, 2.5). A father working as a farmer was associated with a higher risk of childhood injury death from fire/burns (HR = 4.0). In conclusion, the parental SES risk profiles of childhood injury deaths varied with the age and gender of the child, and with the injury mechanism. Therefore, reducing excess injury deaths during early childhood requires preventive efforts targeted at high-risk parents, and based on injury mechanism and on the gender and age of the child.
