Hi lactnetters, I found an article that might be of interest. Title:
Identification of risk factors for delayed onset of lactation
Authors:Donna J. Chapman, MS, RD, Rafael Perez-Escamilla, PhD. Journal of
American Dietetic Association 1999;99: 450-54
Objective: to identify infant feeding, socioeconomic demographic, and
delivery-related factors that affect women's self-reported timing of the
onset lactation.
Design: Longitudinal survey of women from day 1 postpartum until
self-reported onset of lactation. Subjects were interviewed in person on
day 1 postpartum, then surveyed daily by telephone regarding infant feeding
method, breast systoms, and perception of whether the onset lactation had
occurred. Medical records were reviewed.
Subjects/setting: Data were collected from 192 women after they gave birth
to a healthy, term singleton.
Statistical analyses performed: X2 Analyses were used to identify variables
associated with delayed onset of lactation(onset of lactation greater than
72 hours postpartum)> Multivariate logistic regression was used to identify
the independent association of each significant variable with delayed onset
of lactation.
Results: Risk factors for delayed onset of lactation included white/
Hispanic ethnicity, heavy/obese body build, delivery of offspring by
unscheduled cesarean delivery, vaginal deliverywith prolonged stage 2
labor, infant birth weight less that 8 lb, and exclusive formula-feeding
before the onset of lactation.
Applications/conclusions: Women who are at risk for delayed onset of
lactation need additional breast-feeding support during the first week
postpartum. During their hospitalization, these women should be instructed
about the normal lactation process and the possibility that onset of
lactation may occur later than 72 hours postpartum. Frequent nursing ahould
be recommended, as delayed onset of lactation was associated with the lack
of infant suckling.
Sorry, it is so long but I thought you might be interested in these authors
conclusions. Bye, Linda Bojman, MS, RD, CLE living in San Diego, CA
