This paper explores the effect of pregnancy intentions on subsequent consistency of contraceptive use.
Data were drawn from a longitudinal, cohort study of 1,250 women ages 18-19 years. Women completed weekly journals assessing contraceptive use, pregnancy intentions, relationship characteristics, and reproductive outcomes. We examined 14,505 pairs of journal entries completed during the first 18 months of follow-up.
28% of women reported inconsistent use of contraception during the last week. Consistent use increased from 22% to 77% as pregnancy intention decreased and pregnancy avoidance increased. Compared to women who scored 0, the threshold score for an increased odds of consistent contraceptive use was 5 on the avoidance scale (OR=2.1). Women who scored below 4 on the intention scale were more likely to be consistent contraceptive users than women who scored 5 on the intention scale.
Pregnancy intentions strongly predict subsequent consistency of contraceptive use.
