Pulmonary Tuberculosis among Male Inmates in the Largest Prison of Eastern Nepal

Abstract

Introduction The prevalence of Pulmonary Tuberculosis (PTB) is much higher in the prison population than in the general population. This study aims to find out the prevalence of PTB and its associated factors among inmates in eastern Nepal. Methods This cross-sectional study was conducted in Jhumka Regional Prison, the largest male prison of Eastern Nepal from September 2014 to August 2015. Semi-structured questionnaires were used to identify individuals with a cough more than one-week duration among 434 randomly selected inmates. Screening of PTB was done by sputum smear test and/or GeneXpert test. Prevalence of TB was defined as the number of cases detected during the study period divided by the total number of inmates screened during that period. Fisher's exact test was used to find out the association of PTB with related variables. Results A total of 434 inmates were screened for PTB with mean age 35.7 years and body mass index 22.7 kg/m2. A total of 68 inmates had a productive cough of more than a week and two patients were already on anti-tuberculosis therapy at the time of screening. Sixty sputum samples were considered for sputum smear/GeneXpert test and 6 of them (10%) had positive results. The prevalence of TB in the Prison was 1843/100,000 population. Chest pain and abnormal chest auscultation findings were found to be significantly associated with PTB. Conclusions This study showed that there was a high rate of PTB among inmates in Nepal. The results suggest a need for effective screening of PTB and strategies to improve management including reduction of PTB transmission in the prison.
