OBJECTIVES: The objective of this study was to determine if long-acting reversible contraception (LARC) use prior to pregnancy and health plan type were associated with greater likelihood of having an intended pregnancy (IP). METHODS: Women members of the Kaiser Permanente, Northern California (KPNC) integrated health plan aged 15-44 years who became pregnant between 1/1/2010 and 12/31/2012 were identified from KPNC databases. The last contraceptive method used within 2 years preceding pregnancy was determined. Key characteristics were compared among women with IPs vs. those with unintended pregnancies (UPs-unwanted or mistimed). Logistic regression analyses were conducted to determine if health plan type, copays or prior LARC use were predictive of IP, controlling for age, race/ethnicity, marital status, education/income, parity, and select comorbidities. RESULTS: Among women included in the study, 27,498 (61%) had IPs and 17,853 (39%) had UPs. Higher education (47.9% vs. 17.2%), an income ≥$60,000 (55.0% vs. 21.0%), and already having one child (39.0% vs. 21.3%) were significantly (p<0.0001) more common among women with IPs. In comparison to women with IPs, significantly (p<0.0001) larger proportions of women with UPs were ≤24 years old (33.7% vs. 6.5%), single (39.8% vs. 5.5%), and had evidence of comorbidities (7.72% vs. 7.12%). When controlling for key characteristics, women who used LARC methods prior to pregnancy vs. women using non-LARC methods were 2.3-fold (p<0.0001) more likely to have an IP. Women with deductible plans with health savings accounts (HSA) vs. those with non-deductible plans had greater odds of having an IP (1.16, p=0.01). Upon further stratified analysis, prior use of LARC methods was associated with significantly greater likelihoods of having an IP across all evaluated race/ethnicities and education/incomes levels. CONCLUSIONS: Women KPNC members who used LARC methods prior to pregnancy and those who had a HSA were more likely to have an IP than an UP.
