The intrauterine contraceptive device and acute salpingitis: a multifactor analysis

From an indigent population hospitalized with acute salpingitis, 163 patients were compared with 222 control patients from the minor trauma section of the emergency room. Four factors were significantly different between cases and controls: race, type of contraception, number of sex partners, and previous history of salpingitis. A discriminate analysis based on a linear logistic equation demonstrated that each risk factor was independent rather than a reflection of another risk factor. Thus factors associated with race, IUD use, multiple sexual partners, and previous salpingitis increase the risk of salpingitis in the population studied.
