RESUMEN
OBJECTIVE: To study national-level trends in assisted reproduction technology (ART) treatments and outcomes as well as the characteristics of women who have sought this form of infertility treatment. DESIGN: Population-based study. SETTING: Not applicable. PATIENT(S): For CDC: All reporting clinics from 1996-2010. For NSFG: for the logistic analysis, sample comprising 2,325 women aged 22-44 years who have ever used medical help to get pregnant, excluding women who used only miscarriage prevention services. INTERVENTION(S): None. MAIN OUTCOME MEASURE(S): CDC data (number of cycles, live birth deliveries, live births, patient diagnoses); and NSFG data (individual use of ART procedures). RESULT(S): Between 1995 and 2010, use of ART increased. Parity and age are strong predictors of using ART procedures. The other correlates are higher education, having had tubal surgery, and having a current fertility problem. CONCLUSION(S): The two complementary data sets highlight the trends of ART use. An increase in the use of ART services over this time period is seen in both data sources. Nulliparous women aged 35-39 years are the most likely to have ever used ART services.
