Environmental tobacco smoke exposure and pelvic inflammatory disease: a cross-sectional analysis of serum cotinine

Key Points

• The research aims to explore the association between environmental tobacco smoke exposure and the risk of pelvic inflammatory disease in non-smoking women.
• Cross-sectional analysis conducted to assess serum cotinine levels as a measure of ETS exposure.
• Participants included non-smoking women diagnosed with PID and those without.
• Statistical analyses evaluated the correlation between cotinine levels and PID risk.
• Significant association found between elevated serum cotinine levels and increased PID risk.
• Non-smoking women with higher ETS exposure showed greater susceptibility to reproductive tract infections.
