[A case-control study on risk factors for tuberculosis in Yinchuan city].
OBJECTIVE
To study the risk factors of tuberculosis in Yinchuan city and lay a basis for its prevention and control.


METHODS
A matched case-control (119:179) study for the risk factors was carried out. Data were analyzed with single-variable analysis and multiple factor logistic regression analysis.


RESULTS
Single-variable analysis showed that the education background (chi2 = 2.363, P = 0.018), family economic income (chi2 = 3.040, P = 0.002), smoking (chi2 = 2.500, P = 0.012), physical activities (chi2 = 2.330, P = 0.020), bacille Calmette-Guerin (BCG) vaccination history (chi2 = 22.151, P = 0.000), history of exposure to tuberculosis (chi2 = 15.740, P = 0.000) and so on had significant effects on tuberculosis. Multiple logistic regression analysis showed that family monthly income, smoking, physical activity, BCG vaccination history, history of exposure to tuberculosis entered the final regression model (chi2 = 5.880, 7.368, 3.891, 21.127, 14.536; OR = 0.529, 1.571, 0.774, 0.264, 3.978; P < 0.05).


CONCLUSIONS
History of exposure to tuberculosis and smoking should be the risk factors of tuberculosis in Yinchuan. Having much income, physical activities, and BCG vaccination history should be the preventive factors.
