為瞭解初產青少女母親於生產後二年內之避孕、再次懷孕及哺餵母乳等行為，利用台中市民國88年1-12月出生通報資料，篩選年齡小於20歲之本國且於設籍於台中市之初產青少女141人為對象，透過各區衛生所公共衛生地段護士以研究者自行設計之問卷，於民國90年十月至十二月進行家戶訪視，共計完訪76份(完訪率53.9％)，未完成問卷之主要原因為找不到研究對象(佔應訪人數之29.78%)。主要結果包括：(1)初產青少女之在學比率由懷孕時之23.7％至生產二年後降低為2.6％。(2)初產青少女於生產後的二年內，每次都會避孕之比率為17.3％，最常用的避孕方式為子宮內避孕器；再度懷孕的比率為70.7％，主要原因為意外懷孕(45.3％)；再度懷孕後有22.6％會採取人工流產；有49.3％在第一次生產後哺餵母乳，哺餵母乳超過一個月的主要原因是「為嬰兒健康著想」，未哺餵母乳之最主要原因是「沒有母乳」。(3)初產青少女之避孕行為與本身及配偶之年齡、教育程度、工作狀況、婚姻狀況、家庭工坑、生活費用、對避孕之態度、信念及懷孕意向等因素間沒有顯著相關；本人及配偶不反對「初產後二年內再生小孩」及打算再生小孩者之再度懷孕比率顯著較高、終止懷孕比率顯著較低；哺餵母乳行為則僅與本人及配偶對「哺餵母乳」之態度有顯著正相關。本文建議未來針對初產青少女再次懷孕之介入教育可由青少女本身及其配偶之態度與行為意向的改變著手。
