Abstract

Background: Disparities in postpregnancy contraception utilization exist, with low-income women disproportionately undergoing sterilization. We assessed the impact of increased intrauterine device (IUD) availability on rates of female sterilization. Study Design: Hospital billing records were used to identify women with an IUD placement or sterilization within 1 year of a pregnancy at a university hospital between Oct 2005 and Jun 2007. Demographic data were compared between women receiving either an IUD or sterilization. Results: There were 365 sterilizations and 223 IUD placements during the study period. IUD placements doubled over the study period from 6% to 12% of all deliveries, while sterilizations remained stable at 11% (p<.001). Demographic variables were examined for women with either public or private insurance who had financial access to both sterilization (n=253) and IUD (n=223). Women receiving sterilization were slightly older (mean age 31 years versus 30 years, p=.03), of higher parity (median three versus two, p<.01), more likely to have had cesarean delivery (69% versus 31%, p<.001) and more likely to have public insurance (77% versus 23%, p<.001) than women who received IUD. Approximately 45% of women delivering in Oregon in 2007 were publicly insured (2010 Maternal and Child Health Update: States Make Progress Towards Improving Systems of Care. National Governor's Association, Table 6. Available at http://www.nga.org/files/live/sites/NGA/files/pdf/MCHUPDATE2010.PDF, accessed Nov 2011). After adjusting for age, parity and type of delivery, women choosing sterilization were more likely to have public insurance than women choosing IUD (odds ratio 8.4, 95% confidence interval 4.7-14.9, p<.0001). Conclusions: Women choosing sterilization are more likely to have public insurance than women choosing IUD and may represent a continued trend toward nonreversible contraception among women of lower socioeconomic status despite available long-acting reversible methods.
