目的了解四川芦山地震前后重灾县结核病疫情的变化情况。方法对芦山地震前(2011年4月至2013年3月)和地震后(2013年4月至2015年3月),四川省(除雅安市)、雅安市(除重灾县)和重灾县结核病年均登记率进行分析比较,对地震前后重灾县(芦山县、宝兴县和天全县)结核病患者(地震前登记例数446例,地震后登记例数261例)的性别、职业、患者来源及痰涂片情况进行分析。对人群年均登记率进行描述性分析,地震前后登记患者构成比差异采用X2检验,以P〈0.05为差异有统计学意义。结果地震后,重灾县、除重灾县外的雅安市、除雅安市外的四川省结核病年均登记率均有所下降。重灾县结核病年均登记率由74.0/10万[446/(301220×2)×100000/10万]下降到42.7/10万[261/(305337×2)×100000/10万],下降了42.3%[(74.0=42.7)/74.0×100%];除重灾县外的雅安市结核病年均登记率由53.6/10万[162s/(I517633×2)×100ooo/10万]下降到42.5/10万[1307/(i538591×2)×i00ooo/lo万],下降了20.7%[(53.6~42.5)/S3.6x100%];除雅安市外的四川省结核病年均登记率由74.6/10万[120045/(80507830×2)×100000/10万]下降到66.2/10万[107393/(81080386×2)×100000/10万],下降了11.3%[(74.6=66.2)/74.6×100%]。对于重灾县,地震前后患者职业均以农民为主,分别占82.5%(368/446)和84.3%(220/261),差异无统计学意义(X2=0.373,P=0.542);地震前后男性患者分别占74.9Yoo(334/446)和72.40o(189/261),差异无统计学意义(X2=0.523,P=0.542);患者痰涂片阳性率由地震前的31.4%(140/446)增加到地震后的35.6%(93/261),但差异无统计学意义(X2=1.341,P=0.247);地震前后患者来源于追踪的比例由II.4%(51/446)上升到21.1%(65?
Objective To analysis the changes of tuberculosis epidemics in disaster counties before and after Lushan Earthquake. Methods Compare was made on the registration rate and treatment rate among Sichuan province (except Ya'an city), Ya'an (except disaster counties) and disaster counties. Analysis was made on the bases of data of age, gender, occupation, source and registration of patients with tuberculosis in disaster counties before (2011.4 2013. 3) and after (2013. 4-2015. 3) the Lushan Earthquake. Rate and ratio was de.scribed by describe statistics, the difference was made by Chi-square test and P〈0.05, which was considered statistically significant. Results After the earthquake, the incidences of tuberculosis decreased from 74.0/100 000 (446/(301 220 × 2) × 100 000/100 000) to 42.7/100 000 (261/(305 337 × 2) × 100 000/100 000) in disaster counties, from 53.6/100 000 (1628/(1 517 633)42) × 100 000/100 000) to 42.5/100 000 (1307/(1 538 591×2) ×100 000/100 000) in Ya'an city (except disaster counties), the rates of the decreasing were 42.3% ((74.0-42.7)/74.0×100%) and 20.7% ((53.6-42.5)/53.6× 100%). And from 74. 6/100 000 (120 045/(80 507 830 × 2) × 100 00/100 000) to 66. 2/100 000 (107 393/(81 080 386× 2) × 100 000/100 000) in Sichuan province (except Ya'an city), respectively. The rate of decreasing was 11.3 % (74.6-66.2)/74.6 × 100%). Before and after the earthquake, the occupation accounted for most proportion was the farmers, 82.5% (368/446) and 84.3%(220/261), respectively. Accordingly, proportions of men were 74.9% (334/446) and 72.4% (189/261). There were no significant differences in gender and occupations before and after the earthquake (X2 occupation=0. 373, P=0. 542; X0 gender=0. 523, P=0. 542). The smear-positive registration proportion was increased from 31.4% (140/446) to 35.6% (93/261), there were no significant differences in smear-positive registratio
