Abstract

Objectives: Healthcare workers particularly nurses are at risk for latent tuberculosis. However, risk factors for this condition are still controversy. We studied the predictors of tuberculin conversion or recent onset latent tuberculosis in nurses who work in an endemic area of tuberculosis.

Methods: A case-control study was done at Srinagarind hospital, Thailand. Cases were subjects with tuberculin conversion, while controls were subjects with negative results of tuberculin skin test (TST) in two consecutive years.

Results: There were 173 subjects who completed two consecutive TST during 2001-2009. The incidence rate of tuberculin conversion was 34.7% or 60 subjects. In a multivariate model, there were two factors remaining in the final model including age and history of tuberculosis in colleagues. The adjusted odds ratio [95% confidence interval] of both variables were 1.056 (1.004-1.104) and 0.202 (0.044-0.941), respectively.

Conclusion: Older age is the predictor for latent tuberculosis in nurses, while history of tuberculosis in colleagues is the protector.
