過去數年，參與減重課程大多數是女性，其減重後長期維持體重議題，至今已成為一大挑戰。
本研究以質性訪談，探索減重婦女維持體重之經驗。邀請某健康營造中心，參加過八週減重課程者，其減重後至今需達一到兩年，且需已婚並與家人同住之婦女有九位，由於這些人都是家中的主要照顧者。經簽署同意書後，將其納入本研究對象。經深度訪談錄音，將其語音檔轉錄為文字資料，以內容分析來歸納這些文字資料。研究發現顯示：能繼續維持減重體重者比未能成功維持者，體重維持方法多實踐減重飲食原則，如降低飲食熱量，常多應用日常飲食小技巧，並較能執行定期定量的身體活動，如走路、騎腳踏車等，同時較能應用策略協助，如測量食物份量、自我監測、自我學習等。然而，會影響體重的維持之重要因素包括：社交生活、家庭作息改變、文化習俗節慶、他人健康改變等生活事件影響，而增加多吃食物的機會或減少定期身體活動時間。成功維持體重者感受家人多給予支持，但未成功維持者多感受家人傾向不支持或不參與其維持體重的過程。期望本結果提供相關專業人員納入飲食小技巧於減重課程中，發展協助減重者遭遇日常生活事件困擾時的因應技能，還有減重課程最好能邀家人一起參與，以促進體重能被成功的長期維持。

The majority of participants in a planned weight loss program during the past several years were females. The issue of long term weight loss maintenance has proven to be a challenge for these women.
Qualitative research was applied to explore the experiences of women in their attempt to maintain body-weight loss for one to two years after completing a weight loss program. Nine participants who were married and living with their families were recruited due to they were the main caregiver in the family from a community health center. All of the participants had to complete an eight week program designed for achieving successful weight loss. They were invited to participate in this study after their informed consent was received. Data were collected by deep interviews and tape recordings. Content analysis was adopted to analyze the context of the text records. The findings indicated that those who were successful in maintaining weight loss had engaged in regular physical activities and adopted more strategies for diet control, such as measuring intake amount, using self-monitoring and obtaining new information for diet control. However, the key factors for those failing to maintain weight loss included: social life, changes of family life, traditional customs and celebrations, deteriorated health status, more chances to eat and/or reduced regular physical activity time. Those who enjoyed weight loss maintenance received much more support from their family; for those who failed to maintain weight loss, their families did not support their efforts. We expect that these findings can help community health professionals to design weight control program with diet tips to aid participants to cope with daily life influences on diet control. Moreover, it is better to invite the family to participate in the educational program; this will help women with long term weight loss maintenance.
