AB  - OBJECTIVE: To evaluate the association of low socioeconomic status as an
      independent risk factor for unintended pregnancy. METHODS: We performed a
      secondary analysis of data from the Contraceptive CHOICE project. Between 2007
      and 2011, 9,256 participants were recruited and followed for up to 3 years. The
      primary outcome of interest was unintended pregnancy; the primary exposure
      variable was low socioeconomic status, defined as self-report of either receiving
      public assistance or having difficulty paying for basic necessities. Four
      contraceptive groups were evaluated: 1) long-acting reversible contraceptive
      method (hormonal or copper intrauterine device or subdermal implant); 2) depot
      medroxyprogesterone acetate injection; 3) oral contraceptive pills, a transdermal
      patch, or a vaginal ring; or 4) other or no method. Confounders were adjusted for
      in the multivariable Cox proportional hazard model to estimate the effect of
      socioeconomic status on risk of unintended pregnancy. RESULTS: Participants with 
      low socioeconomic status experienced 515 unintended pregnancies during 14,001
      women-years of follow-up (3.68/100 women-years; 95% CI 3.37-4.01) compared with
      200 unintended pregnancies during 10,296 women-years (1.94/100 women-years; 95%
      CI 1.68-2.23) among participants without low socioeconomic status. Women with low
      socioeconomic status were more likely to have an unintended pregnancy (unadjusted
      hazard ratio [HR] 1.8, 95% CI 1.5-2.2). After adjusting for age, education level,
      insurance status, and history of unintended pregnancy, low socioeconomic status
      was associated with an increased risk of unintended pregnancy (adjusted HR 1.4,
      95% CI 1.1-1.7). CONCLUSION: Despite the removal of cost barriers, low
      socioeconomic status is associated with a higher incidence of unintended
