Breast cancer survivors (BCS), particularly Latina BCS, experience weight gain and reduced physical activity (PA) post-treatment increasing the risk for recurrence. There is a lack of evidence on the intensity and type of PA needed to engage cultural subgroups and improve clinical outcomes. This study developed and piloted two non-traditional PA interventions among a diverse sample of BCS.
Twenty BCS (65% Latina; age 25-75) participated in a 2-arm parallel group-randomized pilot study to test the effects of an 8-week Latin dance and Qigong/Tai Chi intervention on PA and body composition. A seven-day pedometer protocol was used to measure steps/week and a bioelectric impedence scale was used to assess BMI and %body fat. T-tests were used to examine preliminary outcomes across both interventions and within intervention arms.
There were no significant changes in steps/week, BMI, or %body fat across or in each separate intervention. A small effect size for increase in steps/day was found among participants in the Qigong/Tai Chi arm (0.10) and low-to-moderate effect sizes for reductions in % body fat overall (0.36), and separately for participants in Latin dance (0.26) and Qigong/Tai Chi (0.46).
Latin dance and Qigong/Tai Chi are engaging and acceptable PA modalities that are promising for improving PA and body fat among diverse, high-risk BCS. Our findings highlight the need to continue to reach and engage high-risk BCS, including Latina survivors, using novel, culturally-sensitive PA interventions. Future studies should extend and more rigorously test these novel approaches to improving outcomes associated with recurrence.
乳腺癌幸存者(BCS),尤其是拉丁裔 BCS,在治疗后会体重增加和减少体力活动(PA),从而增加复发的风险。缺乏关于需要进行哪种强度和类型的 PA 才能使文化亚群参与并改善临床结果的证据。本研究在不同的 BCS 样本中开发并试行两种非传统的 PA 干预措施。
20 名 BCS(65%为拉丁裔;年龄 25-75 岁)参加了一项 2 臂平行组随机试验,以测试 8 周拉丁舞蹈和气功/太极拳干预对 PA 和身体成分的影响。使用 7 天计步器方案来测量每周步数,使用生物电阻抗秤来评估 BMI 和%体脂肪。使用 t 检验来检查两种干预措施和每种干预措施中 PA 的初步结果。
在两种干预措施中,每周步数、BMI 或%体脂肪均无显著变化。在气功/太极拳组中,参与者每天增加的步数有较小的效果量(0.10),总体上(0.36)和分别在拉丁舞蹈(0.26)和气功/太极拳(0.46)组中降低%体脂肪的效果大小为低到中度。
拉丁舞蹈和气功/太极拳是参与和可接受的 PA 方式,对于提高不同风险的 BCS 的 PA 和体脂肪有很大的潜力。我们的研究结果强调需要继续通过新的、具有文化敏感性的 PA 干预措施来接触和吸引高危 BCS,包括拉丁裔幸存者。未来的研究应该扩展并更严格地测试这些改善与复发相关的结果的新方法。
