    Abstract:
    OBJECTIVE: The objective was to evaluate the effectiveness of opinion leaders in raising breast-feeding rates. STUDY DESIGN: A randomized controlled trial of an opinion leader strategy in 18 hospitals in Central New York State compared mothers' intention to breast-feed during baseline and study years. Multivariate logistic regression with a mixed model analyzed the effects on breast-feeding exclusively and on breast- and formula-feeding combined. RESULTS: Obstetric clinicians had a high degree of knowledge about breast-feeding benefits and of perceived responsibility to recommend breast-feeding. Obstetricians, family practitioners, and midwives agreed on the person identified as the opinion leader, in each case an obstetrician who was chief of obstetrics or obstetrics-gynecology. Breast-feeding rates in hospitals with the opinion leader intervention did not differ significantly from those in control-group hospitals during the study year. CONCLUSION: The opinion leader strategy in this case did not improve breast-feeding rates during the study year. Opinion leader strategies may make assumptions about clinician control that are not justified in situations such as breast-feeding.
