懷孕婦女的營養狀況是影響母親與胎兒健康的重要因素，而國內卻缺乏相關資料。本研究的目的在評估嘉南地區婦女懷孕的營養狀況，包括飲食營養素評估與血液營養指標及體位測量，進而了解懷孕婦女可能面臨的營養問題。本調查為橫斷式調查研究，於民國96至98年為期二年間召募嘉南地區醫院婦產科，接受產前檢查的健康婦女，以問卷、24小時飲食回憶法、營養生化檢驗及體位測量等方式收集相關資料，進行資料分析。本研究共完成374位孕婦訪試，樣本年齡平均29歲，懷孕一、二、三期人數分別為36人、122人、216人，平均增加的體重分別為1.6公斤、4.0公斤、9.9公斤，受訪前一個月內有七成有服用營養補充品。孕婦於懷孕一、二、三孕期熱量攝取分別為：1351.3大卡、1548.7大卡、1661.5大卡，醣類攝取量分別為57％、54.2％、54%、蛋白質攝取量分別為15.7％（53公克）、16.4％（63.6公克）、15.9 %（65.9公克）、脂肪攝取量分別為28.1％、30.8％、31.1 % 、鈣407.4毫克，分析結果顯示，隨著懷孕週數增加營養素攝取量有增加之趨勢，熱量、醣類、蛋白質及脂肪攝取量在懷孕一、二、三期之間有顯著差異，孕期的孕婦鈣質、維生素E及第三期孕婦鐵質的攝取量未達「國人膳食營養素參考攝取量」(DRIs)，其他營養素的攝取量都達到或接近建議量；儲鐵的生化指標都顯示鐵的儲存不足。有七成以上之孕婦曾發生害喜，且症狀多發生於第一孕期間，正在害喜的孕婦，其營養素攝取較低。不同孕期、害喜及營養補充品，都會造成孕婦不同之飲食營養素攝取量及血液營養狀況。研究結果將提供相關單位擬訂孕婦營養政策之參考。 The nutritional state during pregnancy is a major factor of pregnant outcome. The purpose of this study was to assess the dietary intakes and nutritional status in Chianan District of Taiwan. The study was carried out from Jan. 2006 to Feb. 2008.The dietary intakes of this cross-sectional study were assessed by 24-hr recalls; anthropometic assessments；the biochemical assessment of Folate, vitamin B12 and iron was performed. We recruited 374regnant women from the obstetric clinics in 3 levels of hospitals.Te participants’ average age was 29 years old, pre-BMI was 21.3 kg/m2, The average energy intakes in the three trimesters were 1351.3 Kcal, 1548.7 Kcal, and 1661.5 Kcal, The results showed that some nutritients average was below the Dietary Reference Intakes (≦75 %DRIs ). The pregnant women experienced morning sickness during their first trimester, giving them inadequate intake of protein, calcium, phourous, riboflavin and vitamin E. In summary, pregnant women in northern Taiwan had inadequate intakes of Calcium, Iron and vitamin E as well as unsatisfactory t vitamin B12 and iron status.
