Objectives: To determine the physical activity patterns among pregnant women at a tertiary care hospital in, Pakistan. Methods: A cross sectional study was conducted through questionnaire for a span of eight months (from 17th July, 2020 till 20th March, 2021) amongst pregnant women visiting Abbasi Shaheed Hospital for ante-natal visit including paramedical staff having 24 to 28 weeks of gestation. With the written consent of participants, the physical activity was assessed by a validated self-reported Pregnancy Physical Activity Questionnaire (PPAQ) having 32 questions to determine the duration; frequency, intensity and type of physical activity during pregnancy. Participants were asked to select the physical activity and time spent on it per day during the current gestational period. From the PPAQ, average weekly energy expenditure in Metabolic Equivalent of Task (MET-h-week) was calculated. Demographic data including age, ethnicity, socioeconomic status, parity, literacy and working status were recorded. Results: A Total of 229 participants of different ethnicities were enrolled. House hold and care giving type of activities of moderate to light intensity were commonly practiced by our pregnant women. Whereas multi gravida were involved in light physical activities. The Punjabi and Baluchi women mostly took occupational type of physical activities. Working women were physically more active than household women. Around 186 (80%) of the participants had no idea that they should take antenatal exercises during pregnancy. Conclusion: The study concluded that house hold and care giving type activities with moderate to light intensity were commonly carried by pregnant women. Majority of them had no knowledge of antenatal exercise. doi: https://doi.org/10.12669/pjms.38.4.4809 How to cite this:Nadeem S, Khatoon A, Rasheed S, Munim TF.
