目標:本研究旨在瞭解原位氏的健康危害行為現況，並探討原位民健康危害行為的影響因素。方法:研究採橫斷性研究，配合嘉義地區2008年整合性篩按活動，選取嘉義縣某地區參與篩梭的原位氏，徵得月意，以結構式問卷進行資料收集。結果:有效樣本共計723人，男性原位氏，有接近甚至超過半數的人有吸菸、飲酒、嚼檳榔方面的經驗，或目前仍維持菸、酒、檳榔等嗜好(吸菸佔58.68%、飲酒佔78.55%、嚼檳榔佔48.9%)，女性是以目前仍持續有飲酒習慣的比例較高，佔38.18%。經邏輯斯迴歸分析調整後，發現男性、青壯年或是教育程度在國中以下、有吸菸、飲酒、嚼檳榔的人，擁有健康危害行為的機率較大;而健康危害行為機率與年齡主現負相關，亦即年紀越大，健康危害行為的機率愈小。結論:吸菸、飲酒及嚼食檳鄉等健康危害行為在原位民族群中相互影響，且男性、青壯年與教育程度在國中以下，比較會採行健康危害行為。建議更積極投入衛生教育、研擬相關政策介入輔導及建立健康的工作文化環境，以降低原位氏的健康危害行為。

Objective: The purpose of this study is to investigate the health-risk behaviors of aborigines in Chia-yi county, specifically the behaviors of smoking, alcohol consumption, and betel-nut chewing.Methods: A cross-sectional survey was administered to aborigines attending an integrated screening program in Chia-yi County. The questionnaire included questions about socio-demographic variables and smoking, alcohol consumption, and betel-nut chewing habits. Results: A total of 723 aboriginal subjects
were enrolled. The rate of smoking, alcohol consumption, and betel-nut chewing was over 50% for males. The rate of alcohol consumption for females was 38.18%. Conclusions: Using logistic regression,we found that the participants who were young men with low education levels had the greatest statistical risk of smoking, alcohol assumption, and betel-nut chewing. These results suggest that information about the adverse effects of smoking, alcohol assumption, and betel-nut chewing should be taught to high-risk groups. More attention to health education programs and policies that are tailored to the aboriginal culture may decrease the health risk behavior among aborigines.
