背景 產後調理是婦女關注的重點，有九成以上的台灣婦女使用生化湯進行調理；但相關的知識卻不足，知識與使用行為的關係也亟待瞭解。目的 本研究旨在探討產婦之生化湯知識、預期效益及其使用行為的相關性。方法 採問卷調查法，以方便取樣，在南部地區醫院等級以上之醫院或坐月子中心，收集產後30日內的婦女共515位。結果 ⑴產婦的教育程度於生化湯使用行為量表得分有顯著性差異；大學與碩士程度均分別高於高中職產婦。⑵生化湯的知識程度與生化湯的預期效益（r=.14, p<.001）、實際使用行為（r =.12, p<.001）均為正相關；生化湯的實際使用行為與預期效益為正相關（r=.11, p<.05）。⑶生化湯實際使用行為之預測因子為「婚姻」、「生化湯知識」及「生化湯預期效益」。⑷產婦生化湯訊息主要來自家庭成員（30.84%），次為大眾傳播（26.65%），最少由醫事人員（16.44%）。⑸整體的生化湯知識程度有半數以上偏向「錯」與「不知道」的程度。⑹有66.6%產婦會接受中西醫藥物幫助子宮收縮，且76%會自行準備與使用生化湯方劑。結論 本研究發現產後婦女在生化湯的正確知識不足、預期效益傾向正面及偏好生化湯使用行為的比率高，可提供健康照護者之臨床照護與在職教育的具體參考，增進產後婦女健康。

Background: Women in Taiwan are concerned about postpartum personal healthcare, and over 90% consume Shenghua soup as part of their postpartum recovery regimen. However, knowledge regarding Shenghua soup is inadequate among this population. Therefore, the correlation between Shenghua soup knowledge and consumption behavior deserves further clarification.Purpose: The study explores the relationships among Shenghua soup knowledge, expected effectiveness, and consumption behavior in postpartum women.Methods: A descriptive and correlational research design recruited a convenience sample of 515 < 30-days postpartum women from local specialty hospitals and postpartum centers.Results: (1) Participant education level had a significant impact on Shenghua soup consumption behavior. Those with bachelor and master school degrees earned a higher average score than those educated to the senior high school level; (2) Knowledge correlated significantly and positively with expected effectiveness (r=.14, p<.001) and consumption behavior (r=.12, p<.001). Consumption behavior correlated positively with expected effectiveness (r=.11, p<.05); (3) Marital status, knowledge and expected effectiveness were identified as significant predictors of Shenghua soup consumption behavior; (4) Principal sources of participant information on Shenghua soup were family members (30.84%), media (26.65%), and medical staff (16.44%); (5) Knowledge scores for over half of participants were in the "wrong" to "no idea" range; and (6) 66.6% of participants took Chinese and Western medicines to help uterine contraction, while 76% had consumed Shenghua soup.Conclusions: Findings indicate that postpartum women in Taiwan have insufficient and incorrect knowledge regarding Shenghua soup; hold positive expectations regarding Shenghua soup effectiveness; and have a high Shenghua soup consumption rate. This study may serve as a postpartum care reference for healthcare professionals to improve the postpartum health of women.
