目的:估算挪威外国出生人群的标准化结核病发病比(SIR)。方法:根据挪威出生人群的性别和年龄别发病率计算外国出生人群的结核病期望发病数。标准化发病比为观察发病数与期望发病数的比值。结果:所有入选国家的结核病期望发病数均在0～3之间;明显低于观察发病数。SIR最高者为非洲(160,95％CI:144～175),最低者为美国/加拿大(0.4,95％CI:0.1～1.0)。索马里的 SIR为 883(95％CI:775～991),越南为122(95％CI:106～139),巴基斯坦为 119(95％CI:105～134),菲律宾为 115(95％CI:91～144),前苏联为49(95％CI:40～57)。所有外国出生人群的SIR为21(95％CI:20～22),人群归因危险度为38％。其中以15～39岁组的SIR为最高(95,95％CI:89～101);65 岁以上组为最低(3,95％CI:2.1～3.3)。此外,15～39岁组的肺外结核SIR也很高(159,95％CI:146～173)。结论:人群的结核病标准化发病比(SIR)因出生地而异。了解移民国当地的结核病流行病学以及移民模式有助于提高预防措施的针对性。
Purpose: To estimate the standardized incidence of tuberculosis (SIR) in Norwegian-born foreign populations. Methods: Based on the gender and age-related prevalence of Norwegian births, the expected number of tuberculosis cases in foreign-born populations was calculated. The standardized incidence is the ratio of the observed incidence to the expected incidence. Results: The expected incidence of tuberculosis in all selected countries was between 0 and 3, significantly lower than the observed incidence. The highest SIR was in Africa (160, 95% CI: 144-175) and the lowest was USA / Canada (0.4, 95% CI: 0.1-1.0). SIR in Somalia was 883 (95% CI: 775-991), Vietnam was 122 (95% CI: 106-139), Pakistan was 119 (95% CI: 105-134), Philippines was 115 (95% CI: 91 ~ 144), the former Soviet Union was 49 (95% CI: 40 ~ 57). The SIR for all foreign-born populations was 21 (95% CI: 20-22) and the population attributable risk was 38%. Among them, the SIR was the highest in the age group of 15-39 (95,95% CI: 89-101); the lowest was in the group of 65+ (3,95% CI: 2.1-3.3). In addition, the SIR of extrapulmonary tuberculosis in the 15- to 39-year-old group was also high (159, 95% CI: 146-173). Conclusion: The standardized incidence of tuberculosis (SIR) in the population varies according to place of birth. Knowing the local tuberculosis epidemiology and immigration patterns in the Migrants country can help to improve the relevance of the precautionary measures.
