HealthDay News — According to research published in the US Centers for Disease Control and Prevention’s Morbidity and Mortality Weekly Report, about 2.5 million American women have had pelvic inflammatory disease (PID).

Researchers from the CDC evaluated data from the US National Health and Nutrition Examination Survey from 2013 to 2014. 

This survey included 1171 sexually-experienced women between the ages of 18 and 44.

Overall, about 4.4% of American women said they’d been diagnosed with PID. The team found that those who had 10 or more male sex partners experienced PID 3 times as often as women with a single partner. 

No significant differences in PID prevalence by age, race, ethnicity or socioeconomic factors were seen.

“These findings highlight differences in reproductive health by sexual behaviors and sexual health history,” the authors write. 

“Given the potential of asymptomatic infection to lead to PID and the substantial costs associated with treatment, it is important that clinicians follow chlamydia and gonorrhea screening recommendations for women to decrease the incidence of PID.”
