Socioeconomic inequalities in injuries treated in primary care in Madrid, Spain

Background Socioeconomic inequalities in injury morbidity are an important yet understudied issue in Southern Europe. This study analysed the injuries treated in primary care in the Community of Madrid, Spain, by socioeconomic status (SES), sex and age. Methods This was a cross-sectional study of injuries registered in the primary care electronic medical records of the Madrid Health Service in 2012. Incidence stratified by sex, SES and type of injury were calculated. Poisson regression was performed. Results A statistically significant upward trend in global injury incidence was observed with decreasing SES in all age groups. By type of injury, the largest differences were observed in injuries by foreign body in men aged 15-44 and in poisonings in girls under 15 years of age. Burns risk also stood out in the group of girls under 15 years of age with the lowest SES. In the group above 74 years of age, wounds, bruises and sprains had the lowest SES differences in both sexes, and the risk of fractures was lower in the most socioeconomically advantaged group. Conclusion People with lower SES were at a greater risk of injury. The relationship between SES and injury varies by type of injury and age.
