目的：本研究旨在探討成年網路使用者之網路健康素養與健康促進生活型態之間的關係，並且加入相關個人背景因素如性別、年齡、教育程度，以及自覺健康狀況和健康資訊搜尋行為等作共同探討。
方法：以20歲以上使用網路之成年人作為研究對象，收集其個人背景資料、健康資訊搜尋行為、自覺健康狀況，另使用網路健康素養量表(eHEALS)、健康促進生活型態簡式量表（HPLP-S）作為測量工具，並採用便利性抽樣，以網路問卷進行調查，總共回收有效問卷493份。
結果：
一、研究對象具有中上程度的網路健康素養能力以及中等程度的健康促進生活型態。
二、不同教育程度、年齡、自覺健康狀況及健康資訊搜尋行為的人在網路健康素養與健康促進生活型態上有顯著差異。以教育程度較高、自覺健康狀況良好、重視健康、健康資訊搜尋行為頻率較高的人其網路健康素養能力較好，健康促進生活型態也較為正向；在年齡上，以20-49歲網路健康素養能力較佳，50歲以上則是擁有較好的健康促進生活型態。三、網路健康素養與健康促進生活型態有顯著正相關。
四、年齡、教育程度、自覺健康狀況、健康資訊搜尋行為和網路健康素養能顯著預測健康促進生活型態，並以自覺「健康重視程度」的預測力最大，能積極預測所有6種層面的健康促進生活型態。
建議：提升成人對健康的重視程度，有助於提升其網路健康素養與健康促進生活型態，而針對不同年齡層，可著重在促進青壯年族群的健康生活型態以及加強中老年人的批判性素養，此外，也須強化健康資訊的傳播及把關健康資訊的品質。

Purpose: This study investigated the association between eHealth literacy and health-promoting lifestyles among adult Internet users. Factors including gender, age, education level, perceived health status, and health information seeking behaviors were also examined.
Methods: Study sample came from participants over the age of 20 who use the Internet. A total of 493 participants were recruited using a self-administrated online questionnaire. Sociodemographics, perceived health status, health information seeking behaviors were assessed. The eHealth literacy scale (eHEALS) and the short-form Chinese Health Promoting Lifestyle Profile (HPLP-S) were used.
Results:
1. The study participants reported moderate to high level of eHealth literacy and moderate level of health-promoting lifestyles.
2. Study participants who were with higher education level, perceiving good health status, paying more attention to health, and with higher frequency of health information seeking behaviors demonstrated better eHealth literacy and health-promoting lifestyles. Those aged 20-49 years old reported better eHealth literacy, and those over 50 years old showed better health-promoting lifestyles.
3. The score of eHealth literacy scale was positively associated with the score of Health Promoting Lifestyle Profile.
4. Age, education level, perceived health status, health information seeking behaviors, and eHealth literacy were predictors of the health-promoting lifestyles. Paying attention to health was positively associated with all six dimensions of health-promoting lifestyles.
Suggestions: Interventions to attract the attention to health among adult Internet users may improve their eHealth literacy and health-promoting lifestyles. For different age groups, interventions should focus on promoting healthy lifestyles of young and middle-aged groups and strengthening the critical literacy of middle-aged and elderly people. In addition, the dissemination and quality of health information must be addressed.
