How Contraceptive Use Patterns Differ by Pregnancy Intention: Implications for Counseling

To increase awareness of issues to include in contraceptive counseling-the objectives of this study were to evaluate: 1) how contraceptive use patterns (eg, non-use), level of effectiveness of contraceptive method, and sociodemographic characteristics may be associated with the occurrence of unintended pregnancy; 2) patterns of health care use for women with intended and unintended pregnancy; and 3) the association between contraceptive use patterns and sociodemographic characteristics. In-person interviews were conducted with 279 women enrolled in a Medicaid managed care health plan who had been pregnant in the last 5 years. Self-reported measures of pregnancy intention, contraceptive use, and health care use were collected. The relationships of pregnancy intention with contraceptive use patterns, level of effectiveness of contraceptive method used, and patterns of recent health care use were assessed. Differences in contraceptive use patterns by sociodemographic groups were assessed. Seventy-eight percent of women reported an unintended pregnancy. Non-use of birth control the month before conception was reported by 57% of women with unintended pregnancies and 84% of women with intended pregnancies. Use of birth control of low effectiveness was reported by 20% of women with unintended pregnancies and 8% of women with intended pregnancies. Non-use or use of contraceptive methods of low effectiveness did not differ for women in different sociodemographic groups regardless of pregnancy intention status. A majority of women reported recent health care use. Health care providers should be aware that women who have no intention for pregnancy may not be using an effective contraceptive method NOR have an effective pattern of contraceptive use.
