Abstract:
This study was aimed at preliminarily assessing the prevalence of latent tuberculosis infection(LTBI)among cattle farming and slaughterhouse workers across Wuxue,Xianning,and Yichang Cities in Hubei Province,and exploring associated risk factors.Data on cattle farming and slaughterhouse workers were gathered via a questionnaire.LTBI detection was performed with a tu-berculin skin test and interferon-gamma release assay,and influencing factors were subsequently analyzed.The LTBI prevalence among cattle farming and slaughterhouse personnel in the three cities was 30.50%,and a higher rate was observed in slaughterhouse workers(39.01%)than cattle farmers(21.63%)(P<0.01).Multifactor analysis indicated that working in slaughterhouses(95%CI:1.582-3.878),having a history of tuberculosis(95%CI:1.377-25.057)or BCG vaccination(95%CI:1.229-3.285),and having a college education or above(95%CI:0.303-0.859)were significant factors influencing LTBI positivity in these personnel.Having more than 30 years of work experience(95%CI:1.303-18.782)was a risk factor for personnel at cattle breeding farms.Among slaugh-terhouse personnel,having a college education or above(95%CI:0.164-0.894),11-20 years of work experience(95%CI:0.122-0.994),or a history of tuberculosis(95%CI:1.661-64.397);performing logistics work(95%CI:3.234-126.424);and working in slaughter-related positions(95%CI:1.209-19.639)were associated with LTBI positivity.Therefore,the slaughterhouse workers in the three cities had higher LTBI rates than the cattle farming workers,thus underscoring the need for increased attention to personnel in logistics and slaughter-related positions.
