          Abstract

          Objective To investigate the prevalence and development of pulmonary tuberculosis(PTB) in Liangyungang, 2008- 2017 and we provide references for PTB surveillance and control in Liangyungang.

          Methods We collected epidemic information of PTB in Lianyungang from 2008 to 2017, and used retrospective epidemiological methods to describe and analyze the epidemic situation of PTB.

          Results From 2008 to 2017, 21 472 cases of PTB were reported in Lianyungang, annual average reported incidence rate (48.29/100 000) and average annual incidence rate of pathogenic positive patients (21.06/100 000) showed a trend of decline year by year ( P<0.01). The morbidityof PTB was higher in November, December and March, while in January, Februaryand October were lower ( P<0.01). Guannan County has the highest incidence rate and Haizhou District has the lowest, the morbidity in the county level was significantly higher than that in the urban area according to the cumulative incidence in the past ten years ( P<0.01). The average age was (50.18±19.62) yrs, the obvious high-incidence age group was 20 -<30 and 50 -<70. Among 21 472 cases, 16 725 patients (77.90%) were farmers, 1 234 (5.75%) were housekeeping, 1 052 (4.90%) were students, and 11.47% were other occupations; there were 15 913 males and 5 559 females, sex ratio between men and women was 2.86:1, 231 cases (1.08%) were migrating population, 21 422 cases (99.77%) were Han nationality, 12 cases (0.06%) were Mongolian nationality, and other minorities accounted for 0.17%. Among the sources of patients, the majority population was due to symptoms (51.04%) and referral (42.84%), proportion of negative etiology was higher (56.12%).The majority were primary treatment (87.35%) and non-severe cases (88.23%), 93.67% of the patients were under the course of treatment and cured. The average wind speed was positively correlated with the reported incidence of PTB ( r =0.256, P<0.05). The linear regression equation between average wind speed and monthly morbidity is Y=2.650 + 0.303X.

          Conclusion The reported incidence of PTB in Lianyungang has been decreasing over the past ten years, and the prevention and control should be further strengthened.

          Abstract

          摘要: 目的 了解连云港市 2008—2017 年结核病流行及发展状况,为连云港市结核病防控工作提供参考依据。 方法收集 2008—2017 年度连云港市肺结核疫情数据资料,运用回顾性流行病学方法描述和分析连云港市结核病流 行状况。 结果 2008—2017 年间连云港市共报告肺结核病 21 472 例,年平均报告发病率 (48.29/10万) 和病原学阳性患 者年平均发病率 (21.06/10万), 均呈逐年下降的趋势 ( P<0.01), 11、12 和 3 月份发病率较高, 1 、2 和 10 月份发病率较低 ( P <0.01); 灌南县发病率最高,海州区最低,各县区间十年累计发病率提示县级发病率明显高于市区 ( P<0.01); 平均年龄 (50.18±19.62) 岁, 20~<30和50~<70 岁为高发年龄段; 21 472 例患者中 16 725 例职业为农民, 占77.90%, 1 234例为家政 家务,占5.75%, 1 052例为学生占4.90%,其余职业共占11.47%;男性15 913例,女性5 559例,男女性别比为 2.86: 1; 流 动人口 231例, 占 1.08%;汉族共 21 422 例占 99.77%,蒙古族 12 例占 0.06%,其他少数民族共占 0.17%。 病人来源中,因 症就诊 (51.04%) 和转诊 (42.84%) 占绝大多数;病原学阴性比例较高, 占56.12%;且多数为初治(87.35%)、非重症病例 (88.23%); 完成疗程和治愈的患者占总数的 93.67%。 月平均风速与肺结核的报告发病率呈正相关 ( r=0.256, P<0.05), 其与该病月发病率之间的线性回归方程为 Y=2.650+0.303X。 结论 十年间连云港市结核病报告发病率总体呈逐年递 减的趋势,但仍不应掉以轻心,应进一步加强全市结核病防控工作。
