親子同室策略對持續純母乳哺餵具有其重要性，但臨床上在推動24小時親子同室面臨諸多挑戰。本研究目的在探討執行24小時親子同室對持續純母乳哺餵之成效，研究設計採回溯性世代研究法，資料收集自2011年1月至2016年12月於北部某醫學中心共計8,555位產後婦女之親子同室紀錄及持續純母乳哺餵追蹤資料進行分析，依照親子同室執行時間分為24小時親子同室與部分親子同室兩種模式，結果顯示24小時親子同室持續純母乳哺餵機率高於部分親子同室，部分親子同室者住院期間純母乳哺餵的機率減少0.55倍（95% CI=0.489-0.625, p＜ .001）、出院一週純母乳哺餵的機率減少0.57倍（95% CI=0.494-0.664, p＜ .001）、出院一個月純母乳哺餵的機率減少0.45倍（95% CI=0.389-0.520, p＜ .001）以及出院二個月純母乳哺餵的機率減少0.38倍（95% CI=0.331-0.443, p＜ .001）。顯見24小時親子同室確實對持續純母乳哺餵是有正面效益，未來在臨床實務鼓勵產婦持續純母乳哺餵更能引用具體的研究結果，提供臨床護理人員照護與指導之重要依據。

Rooming-in care is important for the continuation of exclusive breastfeeding, but it is challenging to provide such care. This study describes the effect of 24-hour rooming-in care on continuation of exclusive breastfeeding. In this retrospective cohort study, data were obtained between January 2011 and December 2016 at a medical center from 8,555 postpartum women under 24-hour rooming-in and partial rooming-in care. Those in 24-hour rooming-in care were more likely to continue exclusive breastfeeding. The odds ratio for exclusive breastfeeding at partial rooming-in decreased at hospitalization (OR = 0.55, 95% CI = 0.489-0.625, p ＜ .001). In the first week postpartum, the women were less likely to exclusively breastfeed (OR = 0.57, 95% CI = 0.494-0.664, p ＜ .001), and the likeliness decreased further at 1 month postpartum (OR = 0.45, 95% CI = 0.389-0.520, p ＜ .001) and even further at 2 months postpartum (OR = 0.38, 95% CI = 0.331-0.443, p ＜ .001). These findings demonstrate the benefits of 24-hour rooming-in care on the continuation of exclusive breastfeeding. In the future, 24-hour rooming-in care should be encouraged, when practicable.
