The social class gradient in childhood injury mortality is steep and increasing, so there is emphasis on targeting injury prevention on the basis of socioeconomic deprivation, to reduce inequalities in health. This paper examines the relationship between medically attended unintentional injury, sociodemographic characteristics and previous injury. This was a cohort study using the control group from a cluster randomised controlled trial of injury prevention in primary care. ⋯ In conclusion, residence in a deprived ward was independently associated with any medically attended injury, with hospital admission and with number of injuries received. However, more than half of those children residing in a deprived ward did not have a medically attended injury and more than 90% did not have a hospital admission. 60% of children who had a medically attended injury and 40% who had a hospital admission do not live in a deprived ward. A combination of a population approach and targeted interventions will achieve the greatest health gain, and is unlikely to widen inequalities in health.
