To evaluate current levels of physical activity and sedentary behaviour among pregnant and non-pregnant adults in Canada.
We ascertained population-based cross-sectional data from the Canadian Community Health Survey (CCHS), 2015-2019, and the Canadian Health Measures Survey (CHMS), 2007-2019. We included adults who were assigned female at birth and were of reproductive age (aged 18-55 years) living in the provinces. We analyzed activity data from validated questionnaires and accelerometers.
We included 53 765 adults from the CCHS and 5321 from the CHMS, weighted to represent 16 million people. Based on accelerometers, both pregnant and non-pregnant adults spent 9.5 hours per day (70% of their time) engaged in sedentary behaviour. Across all survey years, ages, and Canadian regions, pregnant adults, especially those aged under 35 years, spent less time engaged in moderate-to-vigorous physical activity (MVPA) compared with non-pregnant adults. Pregnant adults reported 34.3 minutes (95% CI 30.5-38.2) and objectively accrued 14.9 minutes (95% CI 7.9-21.8) in MVPA per day - 15.1 and 8.9 fewer minutes than non-pregnant adults, respectively. After accounting for self-report bias, only 27.5% (95% CI 24.1-31.0) of the pregnant and 41.1% (95% CI 40.4-41.9) of the non-pregnant adults met the Canadian physical activity guidelines (i.e., ≥150 minutes of MVPA per week).
Physical activity levels are remarkably low among both pregnant and non-pregnant adults, with few meeting current guidelines. Given the substantial physical and mental health benefits, more support is needed to increase pre-pregnancy and prenatal activity in Canada.
评估加拿大孕妇和非孕妇成年人的身体活动和久坐行为的当前水平。
我们从 2015-2019 年的加拿大社区健康调查（CCHS）和 2007-2019 年的加拿大健康衡量调查（CHMS）中确定了基于人群的横断面数据。我们纳入了出生时被指定为女性且处于生育年龄（18-55 岁）、居住在各省的成年人。我们分析了来自经过验证的问卷和加速度计的活动数据。
我们纳入了 CCHS 的 53765 名成年人和 CHMS 的 5321 名成年人，经加权后代表了 1600 万人。基于加速度计，孕妇和非孕妇成年人每天有 9.5 小时（70%的时间）处于久坐行为状态。在所有调查年份、年龄和加拿大地区，与非孕妇成年人相比，孕妇成年人，尤其是年龄在 35 岁以下的孕妇成年人，参与中高强度身体活动（MVPA）的时间较少。孕妇成年人报告每天进行 34.3 分钟（95%CI 30.5-38.2）和客观上积累 14.9 分钟（95%CI 7.9-21.8）的 MVPA，分别比非孕妇成年人少 15.1 分钟和 8.9 分钟。在考虑到自我报告偏倚后，只有 27.5%（95%CI 24.1-31.0）的孕妇和 41.1%（95%CI 40.4-41.9）的非孕妇成年人符合加拿大身体活动指南（即每周进行≥150 分钟的 MVPA）。
孕妇和非孕妇成年人的身体活动水平都非常低，很少有人符合当前的指南。鉴于身体和心理健康的巨大益处，加拿大需要更多的支持来增加孕前和产前的活动。
