Abstract: Latent tuberculosis infection (LTBI) can develop into tuberculosis (TB). The WHO requires the discovery and management of LTBI among high-risk groups. Health care workers (HCWs) constitute a high-risk group. Factors associated with LTBI among HCWs in Thailand needs further study. The current study aimed to explore the factors related to LTBI among Thai HCWs. A hospital-based, matched, case–control study was conducted. All cases and controls were HCWs at a tertiary hospital in northeastern Thailand. Between 2017 and 2019, a total of 85 cases of interferon-γ release assays (IGRAs)-proven LTBI, and 170 control subjects were selected from a hospital (two controls per case). The two recruited controls were individually matched with LTBI cases by sex and age (±5 years). Secondary data were obtained from the occupational health and safety office. Case HCWs had a higher proportion of significant factors than control HCWs (i.e., working closely with pulmonary TB – 94.1% vs. 88.8%, and working in the area of aerosol-generating procedures 81.2% vs. 69.4%). The bivariate conditional logistic regression showed that the occurrence of LTBI in HCWs was statistically significant (p-value < 0.05), particularly with respect to: workplaces with aerosol-generating procedures (AGPs) (crude OR = 1.90, 95% CI: 1.01-3.58, p= 0.041); among HCWs performing AGP (crude OR = 2.04, 95% CI: 1.20, 3.48, p = 0.007; and, absent Bacille Calmette-Guérin (BCG) scar (crude OR = 2.59, 95% CI: 1.50-4.47, p = 0.001). Based on the multivariable conditional logistics analysis, HCWs who performed AGPs while contacting TB cases had a statistically significant association with LTBI (adj OR= 1.82, 95% CI: 1.04-3.20, p=0.035). HCWs who reported the absence of a BCG scar had a statistically significant association with LTBI (adj OR= 2.49, 95% CI: 1.65-5.36, p = 0.001) whereas other factors including close contact with TB (adj OR= 2.44, 95% CI: 0.74, 8.09, p=0123) were not significantly associated with LTBI.
Conclusion: HCWs who performed AGP and were absent a BCG scar had a significant association with LTBI, while other factors played a less critical role.
