Understanding the association between intimate partner violence and sexually transmitted infections among women in India: a propensity score matching approach.

BACKGROUND

Intimate partner violence (IPV) against women can significantly impact their overall health. While numerous studies in developing nations highlight the association between IPV and sexually transmitted infections (STIs), the evidence available within the Indian context remains limited. Therefore, this study aims to fill this knowledge gap by investigating the relationship between exposure to different forms of IPV and the occurrence of STIs, using a quasi-experimental approach.

METHODS

The study used a sample of 63 851 women aged 15-49 years from the latest National Family Health Survey-5. Propensity score matching (PSM) was employed to assess the 'treatment effect' from exposure to IPV (physical, emotional or sexual) in the past 12 months on STIs.

RESULTS

About 12.2% of women (95% CI: 11.7% to 12.8%) reported symptoms of STIs at the time of the survey. Approximately 31.9% (95% CI: 31.2% to 32.7%) of women reported experiencing at least one form of IPV-either physical, emotional or sexual IPV. Of all forms of IPV, physical IPV was the most prevalent, reported by 28.6%, followed by emotional IPV (13.2%) and sexual IPV (5.7%). Women who experienced any form of IPV-whether physical, sexual or emotional-reported a higher prevalence of STIs (17.8%) as compared with those who did not experience any IPV (9.5%). The findings from the PSM analysis indicated that among the three forms of IPV, the impact of sexual IPV on STIs was the most pronounced. The average treatment effect on the treated from exposure to sexual IPV on STIs was 0.15 (95% CI 0.13 to 0.17).

CONCLUSION

This study provides evidence of a significant association between IPV and STIs among women in India and underscores the urgent need for intensified efforts and interventions to address both IPV and STIs, to improve the overall health and well-being of women in India.
