Tobacco use among a population of women attending cervical cancer screening programs in primary health care clinics in South Africa: a cross-sectional study

INTRODUCTION: we determined the prevalence, patterns and factors associated with tobacco use among women presenting for cervical cancer screening in primary health care clinics in Gauteng province, South Africa. METHODS: this study utilized data from an ongoing cross-sectional study commenced in September 2018, in which 749 participants had responded to an interviewer-administered semi-structured questionnaire on socio-demographics, HIV status, tobacco use, family planning methods, sexual and cervical cancer screening behaviours. Data were entered into the web-based research electronic data capture (REDCap). We performed descriptive data analysis and included multivariate logistic regression. We considered a p-value < 0.05 statistically significant. RESULTS: participants´ median age was 38 years (interquartile range: 31-38) with 43.9% (328) reporting being HIV-positive. The prevalence of ever and current tobacco use were 24.3% (182/749) and 17.1% (128/749) respectively. In multivariable logistic regression, participants who self-identified as racial ethnicity other than Black African and those who were HIV positive and not on antiretroviral treatment, had increased odds of reporting current tobacco use ((adjusted odds ratio (AOR)= 5.6, 95% CI: 3.2-9.8) and (AOR= 8.2, 95% CI: 2.0-34.1) respectively). CONCLUSION: current tobacco use is common among women attending cervical cancer screening programs in primary health care clinics in Gauteng Province. Furthermore, study findings suggest the need to integrate tobacco cessation treatments into women´s health and HIV treatment programs.
