创伤性脑损伤（TBI）是全球儿童和年轻人长期残疾的主要原因。然而，关于其发病率的准确信息并不存在。我们的目的是估计在新西兰所有年龄段和TBI severity.Methods的农村和城市人口的TBI的负担，我们做了一个以人口为基础的发病率在城市（汉密尔顿）和农村（怀卡托区）人口在新西兰的研究。我们登记了所有肺结核病例！使用多个重叠信息来源，在2010年3月1日至2011年2月28日期间人群中发生的（入院或未入院，致死性或非致死性）。我们使用泊松分布计算每100 000人年的发病率及其95% CI。我们计算了比率[RR]，以比较性别、种族和居住地（城市、农村）组之间的年龄标准化比率。我们采用直接标准化方法对世界人口的结核病发病率进行年龄分层。每10万人年中轻度TBI的发生率为749例（709-790），中重度TBI的发生率为41例（31-51）。儿童（0-14岁）和青少年和年轻人（15-34岁）占所有TBI病例的近70%。TBI对男孩和男性的影响大于对女性和女孩的影响（RR 1.77，95%CI 1.58-1.97）。大多数TBI病例是由于福尔斯（38% [516/1369]）、机械力（21% [288/1369]）、运输事故（20% [277/1369]）和袭击（17% [228/1369]）。与欧洲血统的人相比，毛利人患轻度结核病的风险更大！(RR 1.23，95% CI 1.08-1.39）。农村人口中重度TBI的发病率（73/100 000人-年[95% CI 50-107]）几乎是城市人口的2.5倍（31/100000人-年[23-42]）。解释我们的研究结果表明，TBI的发病率，特别是轻度TBI，在新西兰，这一数字远远高于以往在其他高收入国家进行的研究结果的估计。在规划预防和TBI护理服务时，应考虑我们的年龄特异性和居住地特异性TBI发病率总体和损伤机制数据。
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 the burden of TBI in rural and urban populations in New Zealand across all ages and TBI severities.Methods We did a population-based incidence study in an urban (Hamilton) and rural (Waikato District) population in New Zealand. We registered all cases of TB! (admitted to hospital or not, fatal or non-fatal) that occurred in the population between March 1, 2010, and Feb 28, 2011, using multiple overlapping sources of information. We calculated incidence per 100 000 person-years with 95% CIs using a Poisson distribution. We calculated rate ratios [RRs] to compare the age-standardised rates between sex, ethnicity, and residency (urban, rural) groups. We used direct standardisation to age-standardise the rates to the world population.Results The total incidence of TB! per 100 000 person-years was 790 cases (95% CI 749-832); incidence per 100 000 person-years of mild TBI was 749 cases (709-790) and of moderate to severe TBI was 41 cases (31-51). Children (aged 0-14 years) and adolescents and young adults (aged 15-34 years) constituted almost 70% of all TBI cases. TBI affected boys and men more than women and girls (RR 1.77,95% CI 1.58-1.97). Most TBI cases were due to falls (38% [516 of 1369]), mechanical forces (21% [288 of 1369]), transport accidents (20% [277 of 1369]), and assaults (17% [228 of 1369]). Compared with people of European origin, Maori people had a greater risk of mild TB! (RR 1.23, 95% CI 1.08-1.39). Incidence of moderate to severe TBI in the rural population (73 per 100 000 person-years [95% CI 50-107]) was almost 2.5 times greater than in the urban population (31 per 100 000 person-years [23-42]).Interpretation Our findings suggest that the incidence of TBI, especially mild TBI, in New Zealand is far greater than would be estimated from the findings of previous studies done in other high-income countries. Our age-specific and residency-specific data for TBI incidence overall and by mechanism of injury should be considered when planning prevention and TBI care services.
