Evaluating the unevaluated: a secondary analysis of the National Survey for Family Growth (NSFG) examining infertile women who did not access care.

Abstract

To characterize the demographic differences between infertile/sub-fertile women who utilized infertility services vs. those that do not. A retrospective analysis of cross-sectional data obtained during the 2011-2013, 2013-2015, and 2015-2017 cycles of National Survey for Family Growth from interviews administered in home for randomly selected participants by a National Center of Health Statistics (NCHS) surveyor was used to analyze married, divorced, or women with long-term partners who reported difficulty having biological children (sub-fertile/infertile women). Demographic differences such as formal marital status, education, race, and religion were compared between women who presented for infertility care vs. those that did not. The primary outcome measure was presenting for infertility evaluation and subsequently utilizing infertility services. Healthcare utilization trends such as having a usual place of care and insurance status were also included as exposures of interest in the analysis. Of the 12,456 women included in the analysis 1770 (15.3%) had used infertility services and 1011 (8.3%) said it would be difficult for them to have a child but had not accessed infertility services. On univariate analysis, compared to women who used infertility services, untreated women had lower average household incomes (295.3 vs. 229.8% of the federal poverty line respectively). Untreated women also had lower levels of education and were more likely to be divorced or never have married. In terms of health status, unevaluated women were less likely to have a usual place for healthcare (87.3%) as compared to women presenting for fertility care (91.9%) (p = 0.004). When examining insurance status, 23.3% of unevaluated women were uninsured as compared to 8.3% of evaluated women. On multivariate analysis, infertile women without insurance were at 0.37 odds of utilizing infertility care compared to women with insurance. Demographic factors are associated with the utilization of infertility care. Insurance status is a significant predictor of whether or not infertile women will access treatment. Data from the three most recent NSFG surveys along with prior analyses demonstrate the need for expanded insurance coverage in order to address the socioeconomic disparities between infertile women who are accessing services vs. those that are not.
