台灣青少年吸菸比率仍偏高。吸菸行為無論在任何年齡層均可能受到複雜之個人、社會與家庭因素所影響。青少年處於特殊發展的階段中，其吸菸行為就更為複雜，可能受到心理、生理、情緒、人際關係、家庭與社會等因素相互影響。目前國內尚無有關國軍士官學校學生吸菸行為之調查研究，此外，了解有關吸菸行為的相關因素是目前國軍在進行菸害防治的重要議題。
此研究目的是探討台灣軍校大學生吸菸行為盛行率及其預測因子。
採橫斷性研究設計，於2004年由全國七所軍校大學共徵募2.477位學生參與此研究，以結構式問卷包括基本屬性、家庭環境、學校環境、吸菸態度、自我效能及吸菸行為收集資料，以描述性及邏輯式迴歸進行資料分析，p<.的為統計上顯著意義。
學生吸菸盛行率為5.79毛，其中12.89毛是入學後開始吸菸及33.3%成為規律吸菸者，第一次吸菸的主要理由是好奇，逃避壓力及困難戒菸是持續吸菸行為的原因，超過809毛的吸菸者企圖戒菸但無法下定決心開始。年齡、同儕影響及自我效能是大學生吸菸行為的主要預測因子。
在這些大學生吸菸盛行率不高，但在入學後4個吸菸學生中有超過一位變成規律吸菸者，因同儕影響及自我效能是主要預測因子，顯示控制香菸及採用預防策略的重要性。

Background: The smoking rate among Taiwanese adoles cents remains high. In any age group， smoking behavior can be influenced by personal， social， and familial factors. In adolescents， many factors， including psychological， physical， emotional， and interpersonal relationships， both social and familial， interact to influence smoking behavior. At present. no data are available on smoking behavior in military students in Taiwan Understanding the factors that influence smoking behavior is a critical element in smoking cessation programs.
Purpose: The purpose of this study was to investigate the prevalence and predictors of smoking behaviors among military university students in Taiwan
Methods: Using a cross-sectional design， 2，477 students were recruited for this study from seven universities across Taiwan. Structured questionnaires were used to collect data covering demographics， family environment. school environment. cigarette smoking attitudes， self-efficacy， and cigarette smoking behaviors. Both descriptive statistics and logistic regression were for the data analysis. A probability threshold of .05 was considered as statistically significant
Results: The prevalence of smoking among students in Taiwan has been recently reported as 5.7%. Of this number， 12.8% started smoking after enrollment in school and 33.3% became regular smokers. The main reason for first contact with smoking was curiosity. Avoiding the stress and the difficulties of smoking cessation explained continuing smoking behaviors. Over 80% of smokers attempted to quit but could not decide when to start. Age， peer influence， and self-efficacy were major predictors of student smoking behaviors.
Conclusions/Implications: Smoking prevalence was not high among these students. However， more than one in four smokers became regular smokers after enrollment at school Tobacco control and prevention strategies proved to be of vital importance， as peer influence and self-efficacy repre sented major predictors of smoking behaviors.
