Methods: The `Yahoo` and `Yam` search engines were used to search for websites using ”weight-loss” and ”body sculpture” as keywords. A total of 120 websites were selected and their contents were analyzed. The basic characteristics and quality of the websites were coded according to predetermined criteria. Pearson correlation coefficient was calculated to test the association between two variables, and t test was used for group comparisons. Finally, regression was used to identify important predictors of quality. Results: More then 80% of the websites made no mention of authorship, sources, or publication date. However, 72.5% did provide the webmaster’s email address, and 30% contained a Q&A function. More than 80% of the websites did not provide information on the minimum daily calorific intake, exercise intensity and quantity, or the ideal goal of weight-loss. Regression showed that after controlling for other variables, websites not involved in commercial activity, or websites with authorship information tended to have better content quality. Conclusion: Overall, most websites did not meet the structural and functional quality criteria used in this study. Furthermore, the content of weight-loss information appeared to be poor. Websites involved in commercial activity may avoid providing certain weight-loss information in order to promote their products. When viewing weight-loss websites, authorship information can be used as a proxy for the quality of content. Periodic assessment of websites is essential in monitoring the quality of weight-loss information on the internet. Health agencies should develop a clear standard for healthy weight-loss, and to provide an effective channel for the general public to obtain the correct weight-loss information. 關聯 台灣公共衛生雜誌,24(6),483-493 資料類型 article dc.creator (作者) 馬藹萱 zh_TW dc.creator (作者) Ma, Sandra Ai-Hsuan - dc.creator (作者) 簡曉靜 zh_TW dc.creator (作者) Chuang, Ying-Chih en_US dc.creator (作者) 吳振龍 zh_TW dc.creator (作者) Wu, Chen-Long en_US dc.creator (作者) 陳育慧 zh_TW dc.creator (作者) Chen, Yu-Hui en_US dc.creator (作者) 莊媖智 zh_TW dc.creator (作者) 莊坤洋 zh_TW dc.creator (作者) Chuang, Kun-Yang en_US dc.creator (作者) 陳富莉 zh_TW dc.creator (作者) Chen, Fu-Li en_US dc.creator (作者) Chien, Hsiao-Ching en_US dc.date (日期) 2005-12 - dc.date.accessioned 14-Dec-2009 13:49:42 (UTC+8) - dc.date.available 14-Dec-2009 13:49:42 (UTC+8) - dc.date.issued (上傳時間) 14-Dec-2009 13:49:42 (UTC+8) - dc.identifier.uri (URI) http://nccur.lib.nccu.edu.tw/handle/140.119/38059 - dc.description.abstract (摘要) 目標：本研究將以瘦身為主題，從訊息呈現的結構性、功能性與正確性等面向，評估瘦身網站的品質。方法：由兩位研究者利用雅虎奇摩及番薯藤兩個搜尋引擎，以「瘦身」、「減肥」為關鍵字進行搜尋，篩選出120個瘦身網站，並使用內容分析法，針對網站基本資料與特性、結構性品質、功能性品質與內容品質等面向，進行瘦身網站內容的譯碼工作。資料分析方面，利用皮爾森積差相關分析檢定雙變項間的相關性，以及利用ttest比較兩組間的差異性，並利用複迴歸分析網站內容品質的重要預測因子。結果：有80%以上的網站未說明作者、來源與時效，有提供電子信箱的網站佔72.5%，有線上提問或評論機制的比例則僅30.0%，有80%以上的網站內容沒有說明每日最低攝取熱量、運動強度、運動類型與熱量消耗，或減重目標等資訊。控制其他變項後，複迴歸分析結果指出，無商業行為、有提供作者資料的網站有比較好的內容品質，且皆達到統計上顯著相關。結論：大部分網站並未達到本研究所採用之結構性或功能性品質指標，且整體上內容品質不佳。有商業行為的網站，可能會為了推銷產品，因而迴避某些瘦身減重的資訊。民眾在檢視減重資訊時，可參考有與作者註記，當作一內容品質之指標。建議未來應定期進行橫斷式資料收集，以觀察網路上瘦身資訊的品質，且相關衛生單位應發展出健康減重的黃金標準，引導民眾以較有效率的方式獲得正確的資訊。 Objectives: The purpose of this research is to assess the structural, functional, and content quality of weight-loss related websites.
