摘要

為了持續檢測臺灣人民之營養健康狀況，在行政院衛生署的補助下，於2005-2008年以家戶為單位，進行了國民營養健康狀況調查，針對6歲（含）以下嬰幼兒、以及19歲（含）以上成人各年齡層。本次調查的抽樣方式與1993-1996年的營養調查接近，皆是分層三段集束法，分別抽出四套樣本。其中一套包含五個地理分層，用來推估全臺灣這些年齡層民眾的營養健康狀況。其他三套樣本分別針對客家人、澎湖人與原住民，當作獨立推估這三類族群的營養健康狀況。總共回收了6,189份問卷以及3,167筆體檢資料。問卷資料包含家戶資料、社會人口基本資料、二十四小時飲食回憶、飲食頻率與習慣、營養知識態度與行為、體能活動量、家族疾病史與骨骼健康情形。體檢資料包括人體測量、血壓、體適能、骨質密度、抽血與驗尿。問卷回應率為65%，在回答問卷的受訪者中，參與體檢的有59%。經統計檢定問卷與體檢回應與非回應者間特徵的差異後發現，僅有少數年齡層樣本在問卷回應上具有性別、年齡、教育程度與省籍的明顯差異。而體檢參與與否有明顯差異者多發生在19-64歲樣本。本調查結果可提供相關領域學者、決策單位與大眾瞭解與改進臺灣之學齡前孩童與成人之營養健康狀況的參考。

The Nutrition and Health Survey in Taiwan (NAHSIT) 2005-2008 was funded by the Department of Health to provide continued assessment of health and nutrition of the people in Taiwan. This household survey collected data from children aged less than 6 years and adults aged 19 years and above, and adopted a three-stage stratified, clustered sampling scheme similar to that used in the NAHSIT 1993-1996. Four samples were produced. One sample with five geographical strata was selected for inference to the whole of Taiwan, while the other three samples, including Hakka, Penghu and mountainous areas were produced for inference to each cultural stratum. A total of 6,189 household interviews and 3,670 health examinations were completed. Interview data included household information, socio-demographics, 24-hour dietary recall, food frequency and habits, dietary and nutritional knowledge, attitudes and behaviors, physical activity, medical history and bone health. Health exam data included anthropometry, blood pressure, physical fitness, bone density, as well as blood and urine collection. Response rate for the household interview was 65%. Of these household interviews, 59% participated in the health exam. Only in a few age subgroups were there significant differences in sex, age, education, or ethnicity distribution between respondents and non-respondents. For the health exam, certain significant differences between participants and non-participants were mostly observed in those aged 19-64 years. The results of this survey will be of benefit to researchers, policy makers and the public to understand and improve the nutrition and health status of pre-school children and adults in Taiwan.
