本研究旨在瞭解國中生含糖飲料之消費現況，並探討不同背景國中生飲用含糖飲料之差異，以及影響國中生含糖飲料消費之因素。本研究以桃園地區九十七學年度國中學生為母群體，經立意取樣選出五所學校，有效樣本為505人。 研究結果發現，研究對象年級越高，含糖飲料知識越豐富飲用越多，而年級越低飲用越少，零用錢越少者及家長社經地位越高者，拒絕飲用含糖飲料自我效能就越高。在外在影響方面，以來自親人曾購買含糖飲料請研究對象飲用較多。影響飲用含糖飲料行為的變項中，「自我效能」、「營養知識」、「自覺體型」、「同儕影響」、「家長影響」、「學校老師影響」、「電視廣告」可解釋飲用含糖飲料行為20％的變異量。其中以「同儕影響力」對學生飲用含糖飲料行為之預測力最大。 本研究建議(1)加強教導學生如何正確選擇飲料，並利用營養午餐的規劃宣導，或營養教育介入與設計教學活動的方式，強化學生之正向態度，使學生能有正確飲用含糖飲料的觀念。(2)家庭教育在飲用行為上亦扮演重要角色，家長可爲學生準備水壺、早餐飲品，並協助學生培養正確的含糖飲料飲用觀念與零用錢的正確使用觀念。
