Smoking adversely affects tuberculosis (TB) outcomes and may be associated with depression and anxiety among people diagnosed with TB in Botswana. We conducted a cross-sectional study among patients newly diagnosed with TB in Gaborone, Botswana, evaluating factors associated with self-reported cigarette smoking. We performed Poisson regression analyses with robust variance to examine whether depressive and anxiety symptoms were associated with smoking. Among 180 participants with TB enrolled from primary health clinics, depressive symptoms were reported in 47 (26.1%) participants and anxiety symptoms were reported in 85 (47.2%) participants. Overall, 45 (25.0%) participants reported current smoking. Depressive symptoms were associated with a higher prevalence of smoking (adjusted prevalence ratio [aPR]: 2.04; 95% confidence interval [CI]: 1.29–3.25) in the adjusted analysis. The association between anxiety symptoms and smoking did not reach statistical significance (aPR: 1.26; 95% CI: 0.77–2.05). Future studies should further investigate these associations when addressing TB care.
BackgroundGetting and maintaining Hepatitis C Virus (HCV) cure is challenging among people experiencing homelessness (PEH) as a result of critical social determinants of health such as unstable housing, mental health disorders, and drug and alcohol use.ObjectivesThe purpose of this exploratory pilot study was to compare a registered nurse/community health worker (RN/CHW)‐led HCV intervention tailored for PEH, “I am HCV Free,” with a clinic‐based standard of care (cbSOC) for treating HCV. Efficacy was measured by sustained virological response at 12 weeks after stopping antivirals (SVR12), and improvement in mental health, drug and alcohol use, and access to healthcare.MethodsAn exploratory randomized controlled trial design was used to assign PEH recruited from partner sites in the Skid Row Area of Los Angeles, California, to the RN/CHW or cbSOC programs. All received direct‐acting antivirals. The RN/CHW group received directly observed therapy in community‐based settings, incentives for taking HCV medications, and wrap‐around services, including connection to additional healthcare services, housing support, and referral to other community services. For all PEH, drug and alcohol use and mental health symptoms were measured at month 2 or 3 and 5 or 6 follow‐up, depending on HCV medication type, while SVR12 was measured at month 5 or 6 follow‐up.ResultsAmong PEH in the RN/CHW group, 75% (3 of 4) completed SVR12 and all three attained undetectable viral load. This was compared with 66.7% (n = 4 of 6) of the cbSOC group who completed SVR12; all four attained undetectable viral load. The RN/CHW group, as compared to the cbSOC, also showed greater improvements in mental health, and significant improvement in drug use, and access to healthcare services.DiscussionWhile this study shows significant improvements in drug use and health service access among the RN/‐CHW group, the sample size of the study limits the validity and generalizability of the results. Further studies using larger sample sizes are necessitated.
Background: Researchers have increasingly recognized the adverse effects of smoking on tuberculosis (TB) outcomes. Smoking may be a maladaptive coping mechanism for depression and anxiety among TB patients; however, this association has not yet been investigated. Design/Methods: We conducted a cross-sectional study among newly diagnosed TB patients between January and December 2019 in Gaborone, Botswana, and evaluated factors associated with cigarette smoking. Using the Patient Health Questionnaire-9 and the Zung Self-Rating Anxiety scale, we collected depression and anxiety scores, respectively; scores of ≥10 indicate depression and scores of ≥36 indicate anxiety. We performed Poisson regression analyses with robust variance to examine whether depression and anxiety were associated with smoking. Results: One hundred and eighty participants with TB were enrolled from primary health clinics. Among all enrollees, depression was reported in 46 (27.1%) participants, while anxiety was reported in 60 (44.4%) participants. Overall, 45 (25.0%) participants reported current smoking, and the median number of cigarettes per day was 10. Depressive symptoms were associated with a higher prevalence of smoking (aPR: 1.82; 95% CI = 1.11, 3.01) after adjusting for sex, HIV status, food insecurity, anxiety, and income. The association between anxiety symptoms and cigarette smoking did not reach statistical significance (aPR 1.26; 95% CI: 0.78-2.05). Conclusions: We found the association between depressive symptoms and smoking among TB patients in Botswana to be significant and the association between anxiety symptoms and cigarette smoking insignificant. Future studies should further investigate these associations when addressing TB care.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
