測試健康生活型態信守問卷之信效度及調查非酒精性脂肪肝病人之健康生活型態信守

非酒精性脂肪性肝病(non-alcoholic fatty liver disease, NAFLD)在台灣及全球盛行率增高，NAFLD的病因與不健康之生活型態有關，目前少有針對NAFLD病患進行健康生活型態及相關因素之研究。本研究目的在發展中文版「健康生活型態信守」問卷及測試其信效度，以及非酒精性脂肪肝病患健康生活型態信守之相關因素調查。本研究設計為橫斷式描述性相關性研究設計，採方便取樣，於高雄某醫學中心肝膽胰內科門診就醫病患，收案對象為20歲以上診斷為非酒精性脂肪肝病患。「健康生活型態信守」問卷之信效度測試結果顯示該量表有良好之內容效度；建構效度以主軸分析作探索性因素分析之結果，萃取出五個因素分別為「改變信守」、「改變障礙」、「結果」、「滿意度」、「動機」，總解釋變異量為67.97%，整體量表Cronbach’s α為.94。 NAFLD病患之人口屬性，以男性居多，平均年齡為50.9歲，慢性病史中無高血壓佔55.8%及無糖尿病佔71.0%居多，生理指標中BMI以重度肥胖(BMI>27)佔65.5%、FLI以≧60%者佔51.6%居多；健康生活型態信守平均得分為110.70分(±21.75)，標準化得分為61.5分，五個因素中平均得分最高為「改變障礙」，最低為「滿意度」；性別、年齡、婚姻、運動習慣及FLI，在健康生活型態信守得分達顯著差異(p<0.05)。本研究結果顯示「健康生活型態信守問卷」可作為NAFLD病患在健康生活型態信守之調查工具，並作為NAFLD病患介入措施在「健康生活型態」改變之成效調查，建議可作為臨床及研究在管理NAFLD個案之評估工具。

The non-alcoholic fatty liver disease (NAFLD) prevalence rate is increased in Taiwan and globally. The causes of NAFLD is related to unhealthy lifestyles. However, few studies have the healthy lifestyles and related factors of NAFLD patients. The purpose of this study was to develop and validate a Chinese version of the“Adherence to a Healthy Lifestyle Questionnaire ” (AHLQ). And surveying of the relationship of healthy lifestyle in patients with NAFLD. This study used a descriptive-correlation design, employed convenience sampling, The patients that criteria of study enrollment with a diagnosed as NAFLD and over 20 years old at a Hepatobiliary and Pancreatic Medicine medical center in Kaohsiung. The results of the AHLQ has good Content validity. Exploratory factor analysis was used to extract five factors which accounted for 67.97% of the variance in total scores-“change of adherence ”,“barrier to change ”,“results”,“ Satisfaction ”, and “ motivations ”. The internal consistence estimates (Cronbach’s α) for the AHLQ was .94. The demographics of NAFLD patients were male, with an average age of 50.9 years. Chronic medical history was 55.8% without hypertension and 71.0% without diabetes. BMI was severe obesity (BMI> 27) was 65.5%, and FLI≧60% was 51.6%; The average score of AHLQ was 110.70 (±21.75), the standardized score was 61.5, and the highest score is the "barrier to change" and the lowest score is the "satisfaction". Significant differences(p<0.05) were observed in gender, age, marriage, exercise habits, and FLI in AHLQ scores. The results of this study show that AHLQ can be used to surveying the adherence of healthy lifestyle in patients with NAFLD, and as a survey of the effectiveness of NAFLD patients' intervention measures in changing "healthy lifestyles". Recommendations can be used as a clinical and research assessment tool for managing NAFLD patients.
