Tuberculosis cases in cross-regional floating population from 2009 to 2017 in Shaanxi Province, China

Background : The cross-regional population of tuberculosis (TB) has become an important part of the prevention and control of TB cases in China with the gradually increasing of floating population. The aim of our study was to explore the main epidemiological characteristics and provide reference for the treatment and management of TB cases in cross-regional floating population in Shaanxi Province. Methods: The data of TB cases in cross-regional floating population from 2009 to 2017 were derived from the National Tuberculosis Management Information Registration System. Descriptive analysis was applied for the baseline demographical, continuous data are expressed as means ± standard deviation and categorical in percentage. The χ2 test, which was implemented as Fisher’s exact test in this study, was applied to categorical variable comparisons. Results: A total of 613 floating TB cases consisting of 413 males (67.4%) and 200 females (32.6%) were registered in Shaanxi province from 2009 to 2017. The difference of gender distribution was statistically significant ( P =0.039). Of the total, 190 cases (31.0%) were smear-positive and 175 cases (28.5%) were negative. From 2009 to 2017, the difference of the gender distribution was not statistically significant ( P =0.732), but the difference in the rate of transferred into original was found statistically significant ( P =0.000). Conclusion: The number of TB cases in cross-regional floating population in Shaanxi Province showed a relatively stable trend from 2009 to 2017. Young males should be given more attentions in TB control because they counted most of the TB cases.
