To report baseline data from a physical activity (PA) intervention for Latina breast cancer survivors, and assess the relationship between PA, fitness, and disability.
Eighty-nine Latina breast cancer survivors from San Juan, PR and Houston, TX (age: 55.4 ± 9.9 years; BMI: 29.87 ± 5.62 kg/m; ≥ 3 months post-treatment) participated in this study. At baseline participants completed fitness testing (six-minute walk test [6MWT], 30-second sit-stand; grip strength, lower and upper extremity and low back strength, shoulder range of motion, balance testing), and assessment of physical activity (PA) and disability. PA was assessed using the International Physical Activity Questionnaire (IPAQ). A subsample (n = 27) received an accelerometer to compare objective versus self-reported PA.
Participants exhibited low PA (M = 76.5 MET·minutes/week; SD = 183.4), poor fitness (6MWT M = 436.4 meters, SD = 99.1; 30s sit-stand, M = 11.6 stands, SD = 3.1), and no detectable disability. In an adjusted model lower extremity fitness was associated with PA, with a one repetition increase in sit-to-stand associated with 49 additional minutes of self-reported PA plus walking per week. The correlation between IPAQ moderate-vigorous PA and accelerometer was 0.38 (p = 0.047).
Latina breast cancer survivors have low physical activity and fitness levels that increase their risk of disability, cardiometabolic comorbidities, and potential cancer recurrence.
报告针对拉丁裔乳腺癌幸存者的身体活动（PA）干预的基线数据，并评估PA、体能和残疾之间的关系。
来自波多黎各圣胡安和得克萨斯州休斯顿的89名拉丁裔乳腺癌幸存者（年龄：55.4±9.9岁；体重指数：29.87±5.62kg/m²；治疗后≥3个月）参与了本研究。在基线时，参与者完成了体能测试（六分钟步行测试[6MWT]、30秒坐立测试；握力、下肢和上肢及下背部力量、肩部活动范围、平衡测试），以及身体活动（PA）和残疾评估。使用国际身体活动问卷（IPAQ）评估PA。一个子样本（n = 27）佩戴了加速度计，以比较客观测量与自我报告的PA。
参与者的PA水平较低（M = 76.5梅脱·分钟/周；标准差 = 183.4），体能较差（6MWT M = 436.4米，标准差 = 99.1；30秒坐立测试，M = 11.6次起立，标准差 = 3.1），且未检测到残疾。在一个校正模型中，下肢体能与PA相关，坐立测试重复次数每增加一次，自我报告的PA加上每周步行时间就增加49分钟。IPAQ中度至剧烈PA与加速度计之间的相关性为0.38（p = 0.047）。
拉丁裔乳腺癌幸存者的身体活动和体能水平较低，这增加了他们出现残疾、心脏代谢合并症和潜在癌症复发的风险。
