臺中市國民小學教師服用維生素/礦物質補充劑狀況之研究

本研究是以臺中市國民小學教師為研究對象，採系統性抽樣抽出10所學校的全體教師為樣本，共計 415 名。 本研究主要目的是在瞭解國小教師使用維生素╱礦物質補充劑之狀況，並探討其知識、健康行為及飲食習慣的相關性。調查結果，國小教師服用維生素者佔 52.0%，服用礦物質者佔 21.0%。在瞭解是否服用維生素╱礦物質補充劑情形與基本資料之相關性，發現與教師年齡有統計顯著相關（ P<0.01 ）。而與性別、婚姻狀況、教師任教年級及是否擔任行政職務則無相關性。飲食狀況方面，則發現有喝牛奶與是否服用維生素補充劑在統計上有意義（ P<0.05 ），其餘的飲食習慣則無相關。至於健康狀況方面，調查結果是自認（不佳、尚可、很好），以及教師知道自己的血壓值（屬於正常、低血壓、高血壓者）二者與是否服用維生素補充劑達統計上之顯著相關（分別 P<0.05，P<0.01 ）。至於在國小教師的健康行為包括目前有無量血壓、自己的血壓值正常否、以及是否定期健康檢查等三項與是否服用礦物質補充劑在統計上達顯著相關性（ P<0.05 ）。以 t-test 統計分析結果，不論有無服用補充劑，在知識得分上無統計之差異。
