AbstractBACKGROUND: Half of US pregnancies are unintended. Understanding risk factors is important for reducing unintended pregnancy rates. AIM: We examined a novel risk factor for unintended pregnancies, impulsivity. We hypothesized that non-planning impulsivity, but not motor or attentional impulsivity, would be related to pregnancy intention. METHODS: Pregnant women (N = 116) completed self-report measures during their second or third trimester. Impulsivity was measured using the Barratt Impulsiveness Scale (BIS-15); subscales measured motor, attentional and non-planning impulsivity (subscale range: 5-20). On each subscale, high impulsivity was indicated by a score of ≥11. Pregnancy intention was assessed by asking women whether they were trying to become pregnant at the time of conception (yes or no). Crude and multivariable-adjusted logistic regression models estimated the cross-sectional association between impulsivity and unplanned pregnancy. RESULTS: Thirty-four percent of women reported that their current pregnancy was unplanned, and 32% had high non-planning impulsivity. Fifty-one percent of women with high non-planning impulsivity reported an unplanned pregnancy versus 25% of women with low impulsivity. Women with high non-planning impulsivity had 3.53 times the odds of unplanned pregnancy compared to women with low non-planning impulsivity (adjusted OR =3.53, 95% CI: 1.23-10.14). Neither motor (adjusted OR =0.55, 95% CI: 0.10-2.90) nor attentional (adjusted OR =0.84, 95% CI: 0.25-2.84) impulsivity were related to pregnancy intentionality. CONCLUSIONS: High non-planning impulsivity may be a risk factor for unplanned pregnancy. Further research should explore whether increasing the use of long-acting reversible contraceptives or integrating if-then planning into contraceptive counseling among women with higher non-planning impulsivity can lower unplanned pregnancy rates.
