本研究之目的在臺灣地區成年人的吸菸盛行情形，並探討與吸菸有關的個人因素。抽樣的第一階段是將臺灣地區分為北、中、南、東、臺北市和高雄市等六層，各層內之鄉、鎮、區先按都市化指標排序後，再按人口比率隨機抽出25個地區。抽樣的第二階段係自各地區隨機抽出六個可訪視的集區，然後將每一集區內相連15戶地址內，18歲以上全體民眾(不論是否有戶籍登記)列為訪視對象。本調查共收到2437人的資料，其中男性1192人，女性1245人。結果發現：(1)未吸菸、偶而吸菸、經常吸菸和已戒菸者在樣本中各佔69.7％，2.3％，24.0％和4.0％；(2)739位有吸菸經驗者中，未曾戒菸、戒菸當中、回復吸菸和戒菸成功者各佔 60.1 ％，1.4 ％，25.4 ％和 131.1 ％；(3) 有吸菸者所佔比率，在二十歲及以上男性樣本之估計值、世界衛生組織標準人口與 1992 年臺灣地區人口組成之標準化吸菸率分別為 50.8 ％， 50.5 ％和 50.7 ％：在女性樣本則分別為 2.9％，2.8 ％和 2.7 ％； (4) 與吸菸「可能性」有關的重要變項包括性別、年齡、教育、藉貫、婚姻、職業、反菸態度、菸害警語的效果評估、及禁菸政策的支持程度。其他變項包括慢性病有無、及對反菸廣告的效果評估等，則與吸菸未達顯著相關。臺灣地區的吸菸率高於歐美國家，極需採取有效的策略予以降低。根據本研究發現，建議戒菸之教育和宣導活動，應特別針對男性、30 歲以下、高中、 閩南籍及原住民、已婚及鰥寡、和職業等級較低者實施。教育策略宜著重反菸態度、警語效果及政策支持等態度的改變。
