背　景：身體活動可以降低懷孕期間疾病的風險，然而許多孕婦於懷孕期間減少身體活動。
目　的：本研究目的欲探討並比較臺灣婦女於各孕期之身體活動量（總量、強度及型態）。
方　法：本研究為橫斷式研究，以立意取樣方式選案。共有581位孕婦完成問卷。以中文版的孕期身體活動問卷測量研究對象之身體活動情形。
結　果：家事／照顧及職業型態的身體活動量於三個孕期呈現顯著的差異，且為懷孕期間最主 要的身體活動型態，分別佔身體總活動量的43.2-54.5% 及42.0-54.0%。經產婦之總體及 家事／照顧型態之活動量較初產婦高。除了運動型態身體活動外，收入者與各種型態 及總活動量呈現負相關。
結 論／ 實務應用：醫護人員應仔細評估胎次、收入對於孕婦身體活動之強度及型態影響，並且鼓勵孕婦與家人或小孩一起參加各種活動。

Background: Physical activity reduces the risk of maternal disorders during pregnancy. However, many pregnant women reduce their levels of physical activity while pregnant.
Purpose: The purpose of this study was to examine and compare the physical activity (total amount, intensity, type) of Taiwanese women during each trimester.
Methods: This cross-sectional survey used purposive sampling to enroll 581 Taiwanese women as participants. The physical activity of participants wasmeasured using theMandarin version of the Pregnancy Physical Activity Questionnaire.
Results: The levels of household/caregiving activity and occupational activity differed significantly across trimesters. Household/caregiving (43.2%Y54.5%) and occupational activity (42.0%Y54.0%) accounted for the largest percentages of total energy expenditure for all three trimesters. In terms of total and household/caregiving activities, multiparous women had significantly higher mean energy expenditures than their primiparous peers. Moreover, income had a pervasive influence on all types and amounts of physical activity and energy expenditures, respectively, with the exception of sports/exercise.
Conclusions/Implications for Practice: Further careful assessment of the types and intensities of physical activity that are suitable for pregnant women in different parity and income categories in Taiwan is necessary. Furthermore, healthcare providers should encourage pregnant women to use strategies that promote their more regular participation in enjoyable physical activities. One of these potential strategies is to do activities together with children, family members, or friends.
