有鑑於當前國內成人過重與肥胖的盛行率逐年增加，由肥胖引起的慢性病亦嚴重威脅國人健康，因此，探討國人過重和肥胖者進行減重行為的影響因子，已是一重要的議題，本研究主要的目的是使用華人家庭動態資料庫，探討體重過重和肥胖成人其進行減重行為之影響因素。
本研究利用中央研究院人文社會科學中心華人家庭研究計畫所實施之「華人家庭動態資料庫（Panel Study of Family Dynamic）」進行分析，合併2000、2003 及2004 年資料，取BMI 大於或等於24 的成人作為研究對象，經篩選後得到1,100 筆資料，作為本研究之樣本。在統計分析上，先將個人特質和個人健康信念變項作次數分配﹔再將各變項與個人進行減重行為變項作卡方檢定﹔最後以邏輯斯迴歸進行分析，探討其影響因子。
研究整體結果顯示，女性、教育程度高、經濟收入低、肥胖情形高、自覺健康狀態好、自覺罹患疾病可能性高、自覺嚴重性（婚姻關係）、自覺嚴重性（人際關係）、自覺嚴重性（個人形象）高，其減重行為的可能性較高﹔而男性、自覺嚴重性（婚姻關係），自覺嚴重性（個人健康）高，其進行維持體重行為的可能性較高。
本研究探討影響過重和肥胖成人減重行為之相關因素的結果，今後對於衛生主管機關宣導成人體重控制活動時，將有助於其焦點團體之選擇；對後續研究者而言，可當作後續相關研究的參考資料。

The prevalence of adult overweight and obese is increasing every year in Taiwan. The association between overweight/obese and chronic health conditions has been widely documented. This study explores the factors that influencing the overweight and obesity who try to lose weight by using the dataset of Panel Study of Family Dynamic.
Panel Study of Family Dynamic is collected by the Program of Study of Chinese Families Research Center for Humanities and Social Sciences (RCHSS), Acadamia Sinica. The studying objects are merged from the years of 2000, 2003 and 2004. The adults whose BMI (Kg/M2) are over 24 were used as the research targets and the sample size is 1,100. For the statistical analysis, the descriptive analysis and the Chisquare test were employed to do the descriptive and correlation analyses. Logistic Regression was used to examine the predictor of the behavior of losing weight.
This study found that groups of the women who have higher education, lower economic income, higher weight, good self-awareness of health condition, higher self-aware susceptibility in marriage relationship, higher self-aware susceptibility in interpersonal relationship, or higher self-aware susceptibility in personal image are more likely to be associated with behavior of losing weight. Nevertheless, the groups of the men who have higher self-aware susceptibility in marriage relationship, higher self-aware susceptibility in personal health are more likely to maintain weight.
Through this study the factors that influence the behaviors of trying to lose weight are found among overweight and obesity. The findings will help future studies to recruit the right targets to be the focus group, and to include those significant factors to do further analysis.
