目的了解重庆市某国有煤矿煤工尘肺合并肺结核的患病情况,为煤工尘肺结核患者的疾病预防和管理工作提供依据。方法对重庆市某国有煤矿自1976—2007年间829例煤工尘肺病例合并结核的情况进行分析。结果重庆市某国有煤矿1976—2007年间煤工尘肺合并结核率为8.20%,显著高于当地人群的肺结核患病率,差异具有统计学意义(χ2=114.03,P<0.01)。煤工尘肺合并结核率随着期别增加而显著增高(χ趋2势=5.23,P<0.05)。采煤、掘进、混合3个工种尘肺合并结核率分别为6.08%、6.60%、16.89%,其中混合工种尘肺合并结核率明显高于两个单纯工种,差异具有统计学意义(P<0.01)。煤工尘肺合并结核率随发病年龄升高而升高(χ趋2势=30.71,P<0.01),煤工尘肺合并结核率随工龄升高无明显改变,差异无统计学意义(x趋2势=2.22,P>0.05)。煤工尘肺合并肺结核患者死亡率为6.15%,死因构成比:肺心病占31.37%,肺结核占23.53%,肺癌占19.61%,肺部感染占15.69%,其他疾病为9.80%。结论尘肺期别越高,煤工尘肺合并结核率越高;混合工种煤工尘肺合并结核率明显高于两个单纯工种;煤工尘肺合并结核的死因前三位是肺心病、肺结核大咳血和肺癌。
Objective To understand the prevalence of pneumoconiosis pneumoconiosis complicated with tuberculosis in a state-owned coal mine in Chongqing, and to provide basis for disease prevention and management of coal worker’s pneumoconiosis tuberculosis patients. Methods A total of 829 cases of pneumoconiosis complicated with tuberculosis in a state-owned coal mine in Chongqing from 1976 to 2007 were analyzed. Results The rate of pneumoconiosis complicated with tuberculosis in a state-owned coal mine in Chongqing from 1976 to 2007 was 8.20%, which was significantly higher than that of the local population. The difference was statistically significant (χ2 = 114.03, P <0.01). Coal miners pneumoconiosis combined with tuberculosis rate increased significantly with the increase (χ trend = 5.23, P <0.05). The rates of pneumoconiosis combined with TBM in mining, driving and mixing were 6.08%, 6.60% and 16.89% respectively, of which the mixed TB pneumoconiosis rate was significantly higher than that of two simple types (P <0.01). Pneumoconiosis combined with tuberculosis rate increased with age (χ trend = 30.71, P <0.01), coal workers pneumoconiosis with tuberculosis rate did not change significantly with age, the difference was not statistically significant (x trend 2 Potential = 2.22, P> 0.05). The death rate of coal worker’s pneumoconiosis with pulmonary tuberculosis was 6.15%. The proportion of death causes was 31.37% for pulmonary heart disease, 23.53% for tuberculosis, 19.61% for lung cancer, 15.69% for lung infection and 9.80% for other diseases. Conclusions The higher the pneumoconiosis stage, the higher the rate of pneumoconiosis combined with tuberculosis in coal workers; the rate of pneumoconiosis combined tuberculosis in mixed workers was significantly higher than that of two simple types; the top three causes of pneumoconiosis and tuberculosis were cough, And lung cancer.
