目的：本研究旨在比較居住於登
革熱警戒區與非警戒區民眾在登革熱
認知上的差異及其影響因子。方法：
以布氏指數３級區分警戒區與非警戒
區，並在台南市之警戒區與非警戒區
內各選取一里之16 歲以上居民，以自
擬結構式問卷進行訪視，取得有效樣
本273 份。問卷包括基本資料及登革
熱認知量表等。資料以頻率分析、平
均值、標準差、卡方檢定、獨立樣本T
檢定及ANOVA 來進行統計分析，並
以逐步複迴歸分析建立登革熱認知之
影響模式。結果：不論警戒區民眾或
非警戒區民眾對登革熱傳播的蚊子、
出沒時間、感染途徑較不清楚，答對
率都不到六成，其中出沒時間答對率
最低，不到三成。居住在警戒區的民
眾對登革熱的認知（10.3±2.5）較非警
戒區民眾的答對率（11.2±1.8）低，且
有統計上的顯著差異（p=0.0005）。警
戒區居民對登革熱的認知主要受年
齡、職業、「是否接受病媒蚊的調查」、
「是否主動獲取登革熱知識」的影
響，而非警戒區居民對登革熱的認知
則受教育程度、職業及「認為政府是
否須加強登革熱宣導」的影響。結論：
民眾對登革熱傳播的蚊子種類、出沒
時間及感染途徑較不了解，且影響警
戒區與非警戒區民眾對登革熱的認知
因子亦不同，政府需加強登革熱傳播
的宣導及針對不同地區居民採取不同
方式，進行登革熱防治的宣導。 This study is aimed to compare
differences of the dengue fever
knowledge between residents in alerting
areas and non-alerting areas and to find
out their impact factors. The alerting
area was defined as where the Breteau
index was 3 and over 3 grades in Apr.
2005. Residents in alerting and
non-alerting areas were interviewed by
questionnaires including demographic
data and knowledge of dengue fever.
X2-test, student’s t-test, and ANOVA
were used to examine differences of
knowledge among the demographic data
and a model to predict knowledge of
dengue fever was analyzed by the
stepwise multiple regression. Results
showed that both of residents living in
alerting area and non-alerting area
poorly understood the species of
mosquito transmitting dengue fever, the
transmission route, and less than 30%
residents didn’t know what time the
mosquito bite them. The mean
knowledge score of dengue fever of
residents living in alerting area was
lower than that of residents in
non-alerting area and there were
statistically significant differences
(p=0.0005). Factors influencing
residents in alerting area to recognize
the dengue fever were age, occupation,
accepting the survey of vector mosquito and initiative to gain the knowledge of
dengue fever. However, factors
influencing residents living in
non-alerting area were education,
occupation and recognizing whether the
government needs to promote the
prevention of dengue fever or not. The
government needs to promote the
transmitting route and time of dengue
fever by using different methods to
educate residents in different areas.
