title: Pelvic inflammatory disease during the post-partum year.
abstract: OBJECTIVE
  To investigate the occurrence of, and risk factors for, pelvic inflammatory disease (PID) occurring during the post-partum year.
  
  
  METHODS
  Demographic and clinical data for women who delivered a term infant with 5-minute Apgar score > or = 8 from 1992 through 1999 at a large urban hospital were extracted from an electronic medical record system.
  
  
  RESULTS
  During the study period, 15 206 deliveries occurred among 12 549 women. PID was diagnosed during the post-partum year of 148 (1.0%) deliveries. In univariate analysis, young age, black race, and both pre-delivery history and post-partum diagnosis of chlamydial and gonococcal infection were associated with PID. In multivariate analysis, only young age and a positive test for gonorrhea before delivery or post-partum were independent predictors of PID.
  
  
  CONCLUSIONS
  Pelvic inflammatory disease was diagnosed during the post-partum year in 1% of women studied. Young maternal age was an important demographic risk factor. Further investigation of post-partum STD acquisition and progression to PID is needed to determine whether women are at increased risk following delivery.
