Stigma and Associated Sex Disparities Among Patients with Tuberculosis in Uganda: A Cross-Sectional Study.

Background:Tuberculosis (TB) is one of the leading causes of death from a single infectious agent globally. Stigma associated with TB encompassing self-, anticipated-, and public-stigma has significant negative effects on treatment adherence. In Uganda, limited data exist on the prevalence of stigma and its relationship with sex among patients with TB. We evaluate prevalence of three types of stigma and their relationship with the sex of patients undergoing TB treatment. Methods:This cross-sectional study was conducted between July 2020 to March 2021 at selected TB clinics in Kampala, Uganda. Eligible participants were aged 18-65 with confirmed TB and starting their prescribed treatment. We collected data on socio-demographics and used 13 items to capture the self-, anticipated-, and public-stigma from which we composed the dependent variables. The primary independent variable was sex. We employed multivariable logistic regression analysis to evaluate the association between sex and the three stigma types. Additionally, we considered potential confounders such as age, HIV, and employment status. Statistical significance was defined as p<0.05. Results:In this study we enrolled 144 participants with a mean age of 35.8 years (standard deviation = 12). Half of the participants (50%, n=72) were female, 44% had a secondary education, 37.5% were unemployed, and 32.6% were co-infected with HIV. The prevalence of self-stigma was 71.1%, anticipated stigma was 75.7%, and public stigma was 41.7%. Significant factors were associated with self-stigma were female sex (adjusted odds ratio (AOR): 2.35 95% CI: 1.02-5.74) and unemployment (AOR: 2.95 95% CI: 1.16-8.58). HIV-positive status was significantly associated with anticipated stigma (AOR: 3.58 95% CI: 1.38-11.23). However, none of the variables we evaluated showed a significant association with public stigma. Conclusions:Our study showed a high prevalence of self, anticipated and public stigma among TB patients. Notably, females and unemployed individuals were at a higher risk of self-stigma, while those with HIV/AIDS and TB were more likely to report anticipated stigma. To combat stigma effectively, interventions should be tailored to cater to sex-specific needs and persons living with HIV. Future research should delve further in determinants of TB-related stigma in high-burden settings.
