Objectives. This study assessed the effect of unintended pregnancy on
breast-feeding behavior. Methods. All women delivering a live birth be
tween January 1, 1995, and July 31, 1996 (n = 33 735), in the 15-count
y central New York region were asked whether they had intended to beco
me pregnant and their breast-feeding plans. Results. Women with mistim
ed pregnancies, and pregnancies that were not wanted were significantl
y less likely to breast-feed than were women whose pregnancies were pl
anned. After adjustment for confounding variables and contraindication
s for breast-feeding, the odds ratios of not breast-feeding remained s
ignificant. Conclusions. Promoting breastfeeding among women with unin
tended pregnancies is important to improve health status.
