Ranges of pregnancy preferences and contraceptive use: Results from a population-based survey in the southeast United States

Abstract

Context: Understanding how pregnancy preferences shape contraceptive use is essential for guiding contraceptive interventions and policies that center individuals' preferences and desires. Lack of rigorous measurement of pregnancy preferences, particularly on the population level, has been a methodologic challenge.

Methods: We investigated associations between prospective pregnancy preferences, measured with a valid instrument, the Desire to Avoid Pregnancy (DAP) scale, and contraceptive use in a representative sample of 2601 pregnancy-capable self-identified women, aged 18-44 years, in Alabama and South Carolina (2017-2018). We used multivariable regression with weighting to investigate how probability of modern contraceptive use, and use of different contraceptive method types, changed with increasing preference to avoid pregnancy.

Results: Desire to Avoid Pregnancy scale scores (range:0-4, 4 = greater preference to avoid pregnancy, median = 2.29, IQR: 1.57-3.14; α:0.95) were strongly associated with contraceptive use among sexually active respondents (aPR = 1.15 [1.10, 1.20]; predicted 45% using contraception among DAP = 0, 62% among DAP = 2, 86% among DAP = 4). Method types used did not differ by DAP score. The most common reasons for nonuse were concern over side effects and not wanting to use a method (32% each) among respondents with mid-range and high DAP scores. Among those with mid-range DAP scores, 20% reported nonuse due to not minding if pregnancy were to occur (vs. 0% among those with high DAP scores).

Conclusions: Pregnancy preferences strongly influence likelihood of contraceptive use. Providion of appropriate contraceptive care to those not explicitly desiring pregnancy must differentiate between ranges of feelings about pregnancy, perceived drawbacks to contraceptive use, and legitimate psychological and interpersonal benefits of nonuse to promote autonomy in contraceptive decision-making.
