Factors associated with improving exercise in ovarian cancer survivors remain unknown. We explored characteristics associated with exercise adherence among women treated for ovarian cancer in the Women's Activity and Lifestyle Study in Connecticut (WALC) randomized controlled trial.
We evaluated adherence among women randomized to the WALC exercise intervention (N = 74). Women had to be exercising ≤ 90 min/week and post-treatment. The intervention included 25 telephone-based exercise counseling sessions over 6 months. Adherence was defined as 150 min/week of moderate/vigorous-intensity exercise. We evaluated factors associated with exercise adherence and duration using multivariate logistic and linear regression. The number of sessions sufficient to achieve 150 min/week was modeled with an unadjusted receiver operating characteristic (ROC) curve.
Women were 57.3 ± 8.8 years old and 1.7 ± 1.0 years since diagnosis. The mean exercise time over 6 months was 166.0 ± 66.1 min/week, and 64.9% of women met the 150 min/week goal. Women attended 22.8 ± 3.6 (92%) counseling sessions. No cancer recurrence during the study (OR = 9.15, 95% CI: 1.09-44.02) and greater session attendance (OR = 1.21, 95% CI: 1.02-1.43) were related to meeting the exercise goal. Greater session attendance (P < 0.01) and higher baseline activity level (P = 0.02) were associated with greater average weekly exercise duration. The ROC curve suggested attending 18 counseling sessions was optimal to meet the exercise goal.
Women attending more counseling sessions or with no cancer recurrence during the study were more likely to meet the exercise goal. More research is needed to understand ideal counseling intensity for ovarian cancer survivors.
Eighteen counseling sessions are sufficient for ovarian cancer survivors to achieve 150 min/week exercise.
与卵巢癌幸存者增加运动量相关的因素尚不清楚。我们在康涅狄格州妇女活动和生活方式研究（WALC）的一项随机对照试验中，探讨了与接受卵巢癌治疗的女性运动依从性相关的特征。
我们评估了随机分配到 WALC 运动干预组的 74 名女性的依从性。这些女性必须在治疗后每周运动≤90 分钟。该干预包括 6 个月内进行 25 次基于电话的运动咨询。依从性定义为每周进行 150 分钟的中度/剧烈强度运动。我们使用多变量逻辑和线性回归评估与运动依从性和持续时间相关的因素。采用未经调整的接受者操作特征（ROC）曲线来确定达到 150 分钟/周所需的咨询次数。
女性的年龄为 57.3±8.8 岁，诊断后 1.7±1.0 年。6 个月内的平均运动时间为 166.0±66.1 分钟/周，64.9%的女性达到了 150 分钟/周的目标。女性参加了 22.8±3.6（92%）次咨询。研究期间无癌症复发（OR=9.15，95%CI：1.09-44.02）和更多的咨询参与（OR=1.21，95%CI：1.02-1.43）与达到运动目标相关。更多的咨询参与（P<0.01）和更高的基线活动水平（P=0.02）与每周平均运动时间的增加相关。ROC 曲线表明，参加 18 次咨询是达到运动目标的最佳选择。
参加更多咨询的女性或在研究期间无癌症复发的女性更有可能达到运动目标。需要进一步研究以了解卵巢癌幸存者理想的咨询强度。
对于卵巢癌幸存者来说，18 次咨询足以使她们达到每周 150 分钟的运动目标。
