The research undertaken in this study utilized a case-control group nested within a prospective cohort which was followed for the first 3 months postpartum. Mothers with mastitis and their controls were requested to complete a self-report questionnaire designed to investigate the association between the potential risk factors, identified from the literature, and lactation mastitis. Logistic regression analyses of the possible risk factors were performed separately for mothers who had not breastfed previously and those mothers who had breastfed at least one infant prior to this lactation. Analysis showed blocked duct(s) and increased levels of stress were the significant predictors for mastitis in mothers who had breastfed a previous infant and blocked duct(s), restriction from a tight bra, attachment difficulties, and nipple pain during a feed were the significant predictors for mastitis in first time breastfeeding mothers.
本研究开展的调查采用了嵌套在前瞻性队列中的病例对照研究组，该队列在产后前3个月进行随访。患有乳腺炎的母亲及其对照者被要求填写一份自我报告问卷，旨在调查从文献中确定的潜在风险因素与哺乳期乳腺炎之间的关联。对从未母乳喂养过的母亲和在此哺乳期之前至少母乳喂养过一个婴儿的母亲分别进行了可能风险因素的逻辑回归分析。分析表明，既往母乳喂养过婴儿的母亲中，乳腺管堵塞和压力水平升高是乳腺炎的显著预测因素；首次母乳喂养的母亲中，乳腺管堵塞、紧身胸罩的束缚、衔乳困难和喂奶时乳头疼痛是乳腺炎的显著预测因素。
