This study examined the association between sexual autonomy and self-reported STIs among women in sexual unions using data from DHS of 31 countries in SSA. The findings revealed that the prevalence of self-reported STIs among the women was 5.8%, and 83.1% of the women surveyed had sexual autonomy. Also, the study showed that there was significant association between sexual autonomy and self-reported STIs among women in sexual unions in SSA. Specifically, women who had sexual autonomy were more likely to have self-reported STIs compared to those who had no sexual autonomy. This finding persisted even after controlling for marital status, multiple sexual partners, wealth quintile, exposure to radio, exposure to television, partner’s educational level and place of residence.
In this study, the overall prevalence of self-reported STIs among women in sexual unions in SSA was 5.8%, and it ranged from 0.3% in Ethiopia to 30.9% in Liberia. Similar findings were reported in previous studies in SSA albeit at the individual country level32,33. A recent multi-country study by Seidu et al.22 reported similar but slightly lower prevalence of self-reported STIs (3.8%) among sexually active men in SSA. Perhaps, the higher prevalence figure recorded in the present study (5.8%) vis-à-vis the study by Seidu et al.22 underscores the vulnerability of women to STIs relative to men34. This calls for increased attention and interventions towards addressing the issue of STIs among women in sexual unions in SSA. Meanwhile, the overall prevalence of STIs reported in the present study (5.8%) is lower than the 19.4% reported by WHO35. The variations in prevalence could be attributed to the differences in time frames for the studies and methods used in data collection. Whereas the WHO’s study relied on clinically confirmed incidence data on four curable STIs (Chlamydia, syphilis, trichomonas and gonorrhea) to determine prevalence, the present study used self-reported data on symptoms of STIs which include having abnormal genital discharge, experiencing a genital ulcer, or having an STI symptom36. Meanwhile, many STIs among women are asymptomatic6 which might have accounted for the low prevalence rate in this study. This calls for increased use of laboratory based or diagnostic studies in determining the prevalence of STIs.
Also, the study showed that women who had sexual autonomy were more likely to have self-reported STIs compared to those who had no sexual autonomy. Similar associations between sexual autonomy and self-reported STI was found by Nankinga et al.33. Available evidence suggests that women with sexual autonomy have higher levels of awareness and decision-making capacity regarding their sexual and reproductive health6,21. This may increase their likelihood to detect and report symptoms of STIs compared to those without sexual autonomy13. Thus, we speculate that the high prevalence of self-reported STIs among women with sexual autonomy is perhaps a function of their assertiveness and willingness to talk about their sexual health which include reporting STIs. Therefore, contrary to the claims by Nankinga et al.33, we argue that the high prevalence of self-reported STIs among women with sexual autonomy may not necessarily be indicative of higher incidence of STIs relative to those without sexual autonomy. As suggested by Chesson et al.6 low levels of sexual health awareness as well as stigma associated with reporting of genital symptoms often curtail reporting or delay healthcare seeking for STIs among women. Thus, increasing women’s level of sexual autonomy even if not protective against STIs, may increase the odds of early detection and reporting of STI-related symptoms, thereby minimizing complications associated with STIs among women. However, further laboratory-based studies are needed to ascertain whether women with sexual autonomy have higher incidence of STIs relative to those without sexual autonomy.
Practical implications
In line with WHO’s Global Health Sector Strategy on STIs 2016-202134, this study provides important data on STI burden in SSA, especially among women in sexual unions34. The multi-country nature of the prevalence estimates improves our understanding of the burden of self-reported STIs in SSA. Additionally, our findings on the association between sexual autonomy and self-reported STIs is important in designing and implementing strategies aimed at reducing burden of STIs in SSA. For instance, increasing the levels of sexual autonomy among women could result in increased self-reporting and early initiation of treatment11,12. This could minimise STI-related complications such as ectopic pregnancy, infertility, pelvic inflammatory disease and chronic abdominal pain among the women6. Even though we speculate that high prevalence of self-reported STIs among sexually autonomous women is probably due to their increased willingness to report and seek treatment compared to women without sexual autonomy, further studies are needed to ascertain this assertion.
Strengths and Limitations
The major strength of this study is the use of the most recent nationally representative cross-sectional datasets of 31 countries in SSA to examine the association between sexual autonomy and self-reported STIs among women in sexual unions. Additionally, the rigorous data collection approach and analysis technique used in the present study enhances the generalisability of our findings to other women in sexual unions in SSA. Despite these strengths, the study has some limitations which need to be acknowledged. First of all, due to the use of cross-sectional study design, only associations between sexual autonomy and self-reported STIs were adduced but not causality. Also, the DHS data does not indicate the exact type of STI among respondents which limit the interpretation of our findings. Furthermore, the prevalence of STIs was limited to self-report and not medically diagnosed or laboratory confirmed which could limit the interpretation of the prevalence of STI among the women. Finally, there is a possibility of underreporting of STIs since some of the women might give socially desirable answers which could create biases in the study findings.
