Incidence of traumatic brain injury in New Zealand: a population-based study

摘要: Summary Background Traumatic brain injury (TBI) is the leading cause of long-term disability in children and young adults worldwide. However, accurate information about its incidence does not exist. We aimed to estimate burden TBI rural urban populations New Zealand across all ages severities. Methods did a population-based study an (Hamilton) (Waikato District) population Zealand. registered cases (admitted hospital or not, fatal non-fatal) that occurred between March 1, 2010, Feb 28, 2011, using multiple overlapping sources information. calculated per 100 000 person-years with 95% CIs Poisson distribution. rate ratios [RRs] compare age-standardised rates sex, ethnicity, residency (urban, rural) groups. used direct standardisation age-standardise world population. Results The total was 790 (95% CI 749–832); mild 749 (709–790) moderate severe 41 (31–51). Children (aged 0–14 years) adolescents 15–34 constituted almost 70% cases. affected boys men more than women girls (RR 1·77, 1·58–1·97). Most were due falls (38% [516 1369]), mechanical forces (21% [288 transport accidents (20% [277 assaults (17% [228 1369]). Compared people European origin, Maori had greater risk 1·23, 1·08–1·39). Incidence (73 [95% 50–107) 2·5 times (31 [23–42]). Interpretation Our findings suggest TBI, especially far would be estimated from previous studies done other high-income countries. age-specific residency-specific data for overall by mechanism should considered when planning prevention care services.
