研究目的：本研究目的是以「台灣地區2002年國民健康促進知識、態度與行為調查」資料進行分析，估計台灣地區檳榔嚼食率及吸菸高盛行率之行職業別。
研究方法：資料來源為行政院衛生署「台灣地區2002年國民健康促進知識、態度與行為調查」，調查中將行職業分為9類、15類，詳細職業別分為99類。
以描述性分析計算行業及職業別中嚼食檳榔、吸菸率等比較。
研究結果：以行業別而言仍嚼食檳榔盛行率中以農林漁牧狩獵業21.67％（95％CI=19.47- 23.86）較高，其次為製造業、礦業、營造業、公共事業16.32％（95％CI=15.17-17.47），運輸及通訊業為16.28％（95％CI= 12.49- 20.08）。職業別中以建築業中低技術工匠（泥瓦匠、油漆匠、修理水管或裝置）最高43.07％（95％CI=37.81-48.33），其次為計程車司機、公鐵路局或客運車司機、貨車司機、遊覽車司機35.06％（95％CI= 29.39- 40.72）。
仍吸菸盛行率中以農林漁牧狩獵業40.7％（95％ CI=38.08 -43.32）較高，其次為運輸通訊業佔37.40％（95％CI=32.43-42.38）。職業別中吸菸盛行率以司機 69.47％（95％CI=59.22-79.92）最高，其次為建築業中的低技術工匠（泥瓦匠、油漆匠、修理水管或裝置） 65.54％（95％CI=60.50 -70.59）。
討論：本研究顯示台灣行職業別檳榔嚼食盛行率、吸菸盛行率確實會因行職業別不同，分析發現在兩者中就業者比無業者高，詳細的高盛行率行職業別為建築業中低技術工匠（泥瓦匠、油漆
匠、修理水管或裝置）及計程車司機、公路局、鐵路局或客運車司機、貨車司機、遊覽車司機、司機都有較高之兩者盛行率。
本研究結果對介入目標群提供預防計畫來減低盛行率提供一個可貴的資訊，依據全國性健康調查做週期性評估台灣地區盛行率趨勢是必須的。

Aim:
The aim of this study is to analyze the data of“2002 National Survey on Knowledge, Attitude and Practice of Health Promotion in Taiwan”, and to identify the professions with the high prevalence rates of betel quid chewing and cigarette smoking in Taiwan.
Methods:
The analysis was derived from “2002 National Survey on Knowledge, Attitude and Practice of Health Promotion in Taiwan”, Department of Health, Executive Yuan. In this survey, professions were classified into 9 categories, occupations were classified into 15 categories, and the detailed subdivision of occupations were classified into 99 categories. This study conducted a descriptive analysis for the comparisons of betel quid chewing rate and smoking rate, between professions and occupations.
Results:
In professions, the highest prevalence rate of betel quid chewing was the agricultural or fishery, 21.67% （95%CI=19.47-23.86）, followed by manufacturing industry, mining industry, construction industry and public utility, 16.32% （95%CI=15.17-17.47）, and transportation and communication industry, 16.28% （95%CI=12.49-20.08）. In occupations,
the highest prevalence rate was the low technique workers （bricklayers, painters, plumbers） of construction industry, 43.07% （95%CI=37.81-48.33）, followed by taxi driver, engineers or bus drivers, truck drivers and sightseeing bus drivers, 35.06% （98%CI=29.39-40.72）. However, in smoking rate, the highest was in agricultural or fishery, 40.7% （95%CI=38.08-43.32）, followed by transportation and communication industry, 37.40% （95%CI=32.43-42.38）. In occupations, the highest smoking rate was in drivers, 69.47%（95%CI=59.22-79.92）, followed by low technique workers （bricklayers, painters,plumbers） of construction industry, 65.54% （95%CI=60.50 -70.59）.
Discussion:
This study showed that the prevalence rates of betel quid chewing and the prevalence rates of smoking in Taiwan were very different in accordance with professions and occupations. The results also showed that employed have higher prevalence rate than unemployed. In particular occupations, the highest prevalence rates were in low technique workers （bricklayers, painters,plumbers） of construction industry and taxi driver, engineers or bus drivers, truck drivers and sightseeing bus drivers.
The result of this study may provide important information to target preventive program. It also provide a valuable standard for interfering in targeted group to conduct screening and health education for reducing prevalence rates. It is necessary to conduct periodicity estimation according to national health survey as a trend for estimating prevalence rate in Taiwan.
