本研究主要目的在瞭解參加健康查者的攝鈉行為，並探討與該行為有關之背景因素及健康信念。在民國八十一年十一月九日至八十二年一月十七日期間，以參加某教學醫院住院式全身健康檢查者為對象，利用問卷取得有效樣本 220 人之資料。 結果發現：(1) 攝取高鈉食物的頻率平均每週為 4.6 次；(2) 男性、40 歲及以下、國中及以上程度、有職業、無慢性病、及有心血管疾病家族史者，其攝取高鈉食物的頻率較高；(3) 與攝取高鈉食物頻率有關之因素主要包括心血管疾病家族史及自覺採取低鈉飲食的障礙因素。欲鼓助民眾採取低鈉飲食，介入計畫應從障礙因素之減少著手。

　　　　　The purpose of this study was to understandsodium intake and related factors among participants undergoing a physicalexamination. Questionaires were employed for data collection. Two hundred twentyadults who entered a teaching hospital for physical examination from Nov. 9,1992to Jan. 17,1993 were interviewed. The results indicated that (1)the averagefrequency of sodium intake was 4.6 times per week; (2)the subjects mone likelyto have a high sodium intake were male, aged 40 years and under, had a middleschool or higher educationwereemployed, and had no chronic disease, or CVDfamily history. (3)CVD family history and perceived barrier to low sodium intakewere significantly associated with the frequency of sodium intake. In order toencourage people to have a low sodium diet, an interventional program should befocused on managing or decreasing the barriers to having a low sodium diet.
