Introduction: The purpose of this study, conducted in a multiethnic population in Hawaii, was to estimate the prevalence of breastfeeding at six months of age, exclusive and otherwise, as well as to identify positively and negatively associated factors.
Methods: A content-valid survey was conducted among a random stratified sample, and a printed questionnaire was sent to mothers of infants aged 7-10 months. A response rate of 70% yielded 701 completed surveys.
Results: At six months after birth, some breastfeeding was practiced by 54% of respondents. The rate of exclusive breastfeeding was approximately 16% at six months. Race and ethnicity assessment showed that Whites had the highest rates and Filipinos the lowest. Formula use in the hospital was most significantly associated with lower breastfeeding rates at six months.
Conclusions: Exclusive breastfeeding for six months, even in a state with extremely high initiation rates, is seldom achieved. Formula use in the maternity units should be reduced, and intensive targeted study and education of the Filipino community should be undertaken.
