目的 以台中地區某醫學大學之大學部學生為對象，探討：(1) 99、101與103年網路成癮的年代趨勢；(2) 網路成癮與健康相關狀態之關係。 材料與方法 本研究研究對象為99、101、103學年度中部地區某醫學大學之大學部學生，採用「99年網路成癮和健康結果之相關研究」、「101年大學生霸凌受害經驗與網路成癮之關係」與「科技部103年大專生研究計畫：低頭省思─智慧型手機及其應用程式APP與大學生日常生活型態及健康之關聯性」之部分自填式橫斷資料進行次級資料分析，所得總樣本數1,766人。自變項為手機搭配網路狀況、健康相關狀態（吸菸、運動習慣、身體質量指數、生理與心理適應、憂鬱），依變項為網路成癮，以網路成癮量表進行測量。以SAS9.4版統計軟體進描述性統計、卡方檢定、t檢定、多變項邏輯斯複迴歸來進行分析。 結果 網路成癮比率以99年26.45%顯著高於103年19.97%與101年19.64%，存在年代趨勢差異，經性別分層並調整社會人口學與健康相關狀態之後，網路成癮則不存在年代趨勢。網路成癮與健康狀況之關係：女性網路成癮與外在生理症狀、憂鬱有關；男性網路成癮與自覺健康狀況、身心適應狀況、憂鬱有關。 結論與建議 在智慧型手機盛行前後的大學生世代，網路成癮趨勢在調整其他影響因素後，並無顯著之年代趨勢，但此現象之機制仍有待進一步探討。本研究發現大學生之網路成癮與心理健康有關，此結果供相關教育單位與輔導單位參考。
