Despite the known benefits of breastfeeding, many women do not breastfeed their infants or stop breastfeeding early. This study examines the effects of prenatal intention and initial breastfeeding experiences on breast-feeding initiation and duration among 1,665 U.S. women completing questionnaires on infant feeding practices. Outcomes included no initiation of breastfeeding at birth and termination at <10 weeks, 10 to <20 weeks, or 20 to <30 weeks. Predictor variables included intended breast feeding duration and early breast feeding experiences with analyses controlling for demographic characteristics, previous breastfeeding experience, and prenatal intentions to work after delivery. Prenatal intentions to never initiate or to stop breastfeeding early were significant risk factors for all breastfeeding outcomes. Initial breastfeeding experiences were significant risk factors for early termination. This study supports using the intention construct from the theory of reasoned action to predict initiation of behavior but suggests the need to include initial experience when predicting maintenance of behavior.
尽管母乳喂养有诸多已知益处,但许多女性并不对婴儿进行母乳喂养,或过早停止母乳喂养。本研究调查了产前意愿和初始母乳喂养经历对1665名填写婴儿喂养习惯调查问卷的美国女性母乳喂养开始情况和持续时间的影响。结果包括出生时未开始母乳喂养以及在小于10周、10至小于20周或20至小于30周时停止母乳喂养。预测变量包括预期母乳喂养持续时间和早期母乳喂养经历,并对人口统计学特征、既往母乳喂养经历以及产后工作的产前意愿进行分析控制。产前从未开始或过早停止母乳喂养的意愿是所有母乳喂养结果的重要风险因素。初始母乳喂养经历是早期停止母乳喂养的重要风险因素。本研究支持使用理性行动理论中的意愿结构来预测行为的开始,但表明在预测行为的维持时需要纳入初始经历。
