Figure B. Pelvic Inflammatory Disease — Lifetime Prevalence* Among Sexually Experienced Women† Aged 18–44 Years by Race/Ethnicity and Previous STI‡ Diagnosis, National Health and Nutrition Examination Survey (NHANES), 2013–2014

* Prevalence estimates based on response to the question, “Have you ever been treated for an infection in your fallopian tubes, uterus or ovaries, also called a pelvic infection, pelvic inflammatory disease, or PID?”. Estimates were weighted to be nationally representative of the U.S. population, accounting for unequal probabilities of selection and nonresponse.

^† Based on a response of “Yes” to the question, “Have you ever had vaginal, anal, or oral sex?”.

^‡ STI = sexually transmitted infection. Participants who have been told by a doctor or other healthcare professional in the last 12 months that they had chlamydia or gonorrhea or have ever been told they have herpes, human papillomavirus, or genital warts.

NOTE: Error bars indicate 95% confidence intervals. Prevalence estimates among non-Hispanic Black women with a previous STI diagnosis have a relative standard error >40% but <50%.
