本研究採用相關調查法以及部分質性分析法，探討護理學生吃早餐的頻率與其在校學業成就的關係。以北部地區某護專新生710名為樣本，自1999年9月至2000年1月之上學期為資料分析時間點，比較此群體護生在四個月的學期中，以電腦刷卡紀錄吃早餐次數（基於此校地理位置特殊之理由），新生被要求一律在校用餐是家長和學校總務處的約定，並已事先繳費），以作者自訂吃早餐的頻率高低（高於所有早餐次數的85％爲頻率高；低於所有早餐次數的60％爲頻率低）與該學期期末總成績及班級排名求相關。結果顯示：越少吃早餐的護生其六項學業成績、及在該班級的成績排名也越差；反之則越高，且達統計意義(p<.001)；同時我們也發現那些經常忽略早餐的學生，在以健康促進行爲量表當評估工具時，也出現較多不良的健康促進行爲(p<.001)；在質性分析中也反應了她們不吃早餐的原因和不適當的觀念。這些結果顯示吃早餐的頻率與學業成就有關係，而此結果亦可以作爲進一步校園青少年健康促進的重要依據。

This survey by correlation study with partial qualitative design examined the effect of attendance at breakfast with school achievement in 710 first-year nursing students at a nursing institute in Northern Taiwan. Dietary attendance cards were scanned by computer before each meal. Since the school is located at a geographically isolated suburban area, this program was compulsory for all first-year nursing students and was included in the tuition fee. Comparison of attendance at breakfast over the four-month semester (from September 1999 to January 2000) and final semester class ranking showed a lower attending rate of breakfast (attendance at breakfast equal to or under 60% of mean times in a 4-month semester) was significantly associated with lower scores on tests in six individual classes and a class rank; while a higher frequency of breakfast attendance (attendance at breakfast equal to or over 85% of mean times in a 4-mouth semester) was significantly associated with higher scores on tests in six individual classes and a higher class rank (p < .001). To determine the relationships between frequency of attending breakfast and practicing health promotion behaviors, the Chinese Health Promoting Scale was used. We also found that those who skipped breakfast frequently had more negative health promotion behaviors than those who attended breakfast more regularly (p < .001). These results indicate that school achievement is negatively affected when nursing students omit breakfast. The research outcome supports the importance of breakfast in school achievement.
