Lifestyle is the first-line treatment for women with polycystic ovary syndrome (PCOS). This study examines the physical activity (PA) levels and sedentary behaviours of women with and without PCOS, and their alignment with the PCOS PA guideline.
This cross-sectional study on women (aged 22-27 years) in the Australian Longitudinal Study on Women's Health was conducted in 2019 using data collected in 2017. Self-reported PA levels and total daily sitting time (ST) of women with (n = 7051) and without (n = 796) self-reported PCOS were presented, stratified by body mass index (BMI) and a combined overweight/obese group.
71.0% and 56.7% of the entire study cohort achieved PA levels recommended for weight maintenance and weight loss, respectively. Overall, PA levels were lower and ST was higher in women with than without PCOS. In each BMI category, similar proportions of women with and without PCOS met the PA guidelines but became lower as BMI category increased. Fewer overweight/obese group women with than without PCOS aligned with recommendations for weight maintenance (58.7% vs 65.7%, P = .003) or weight loss (45.1% vs 50.3%, P = .032). ST ≥8 h/d was observed in two-thirds of women with and without self-reported PCOS similarly before and after stratifying by BMI.
High sedentary behaviour was extremely prevalent. Although the majority of women met PA recommendations for weight maintenance, only one in two overweight/obese women met PA recommendation for weight loss. Overweight/obese women with PCOS were more likely to participate in insufficient PA and require increased support to achieve sustainable healthy lifestyle.
生活方式是多囊卵巢综合征（PCOS）女性的一线治疗方法。本研究检查了患有和不患有 PCOS 的女性的体力活动（PA）水平和久坐行为，以及它们与 PCOS PA 指南的一致性。
这项在澳大利亚女性纵向健康研究中的横断面研究于 2019 年进行，使用了 2017 年收集的数据。报告了患有（n=7051）和不患有（n=796）自我报告的 PCOS 的女性的自我报告的 PA 水平和总每日久坐时间（ST），并按体重指数（BMI）和超重/肥胖组进行分层。
整个研究队列中，分别有 71.0%和 56.7%的女性达到了维持体重和减肥的推荐 PA 水平。总体而言，患有 PCOS 的女性的 PA 水平较低，ST 较高。在每个 BMI 类别中，患有和不患有 PCOS 的女性达到 PA 指南的比例相似，但随着 BMI 类别的增加而降低。超重/肥胖组中，与维持体重（58.7%比 65.7%，P=0.003）或减肥（45.1%比 50.3%，P=0.032）的建议相符的女性比例较低。患有和不患有自我报告的 PCOS 的女性中，有三分之二的人在按 BMI 分层前后，ST≥8 小时/天。
高度久坐行为极为普遍。尽管大多数女性符合维持体重的 PA 建议，但只有一半的超重/肥胖女性符合减肥的 PA 建议。患有 PCOS 的超重/肥胖女性更有可能参与的 PA 不足，需要增加支持以实现可持续的健康生活方式。
