Other data supports this finding - I was at the FASEB experimental biology
meeting in DC in April (mostly basic science stuff, but some breastfeeding
topics in the nutrition section), and a similar topic was presented as a poster
there. The authors looked at maternal obesity as a factor contributing to
failure to initiate breastfeeding in a society where breastfeeding is nearly
universal. They studied Danish women and found that maternal obesity is the
PRIMARY consistent predictor of non-initiation or early termination of
breastfeeding in that study cohort. Full abstract is here:
Abstract # 3919
Maternal obesity and exclusive breastfeeding (EBF) success in Danish women

Maternal prepregnant overweight [body mass index (BMI) 25.0-29.9 kg/m2] and
obesity (BMI >30.0 kg/m2) interfere with the initiation of lactation and are
associated with shortened durations of breastfeeding. It is not known if these
associations persist in populations where breastfeeding is nearly universal.
Therefore, we investigated how maternal prepregnant BMI is associated with the
initiation and duration of EBF in a subset of mother-infant dyads from the
Danish National Birth Cohort. We limited our analyses to dyads who ever
breastfed, 98% of our sample. Among these 9884 women, the mean prepregnant BMI
was 23.6 kg/m2. Using logistic regression adjusted for potentially confounding
factors, we found that overweight [odds ratio (OR) = 1.5, P < 0.01] and obese
women (OR = 1.8, P < 0.01) were less successful at initiating lactation
(defined as EBF at 5 d postpartum) than normal-weight women (BMI = 18.5-24.9
kg/m2). Using proportional hazards regression adjusted for potentially
confounding factors, we found higher rates of EBF discontinuation among women
who were overweight [relative risk (RR) = 1.13, P < 0.0001] or obese (RR =
1.17, P < 0.0001) compared to normal-weight women. These results suggest that
excess maternal prepregnant BMI, even in a population of women who are very
successful breastfeeders, may impair lactational performance. [Supported by NIH

many times they are willing to share a pdf file of posters that have been
presented recently.
