Weight management after breast cancer (BC) treatment in African American (AA) women is crucial to reduce comorbid conditions and health disparities. We examined feasibility and potential efficacy of commercial eHealth/mHealth tools for weight management in AA BC survivors in New Jersey. Participants (N = 35) were randomized to an intervention (SparkPeople) plus activity tracker, Fitbit Charge (n = 18), or wait-list active control group (Fitbit only, n = 17). Anthropometric, behavioral, and quality of life (QOL) outcomes were collected at baseline, 3, 6, and 12 months. Differences in outcomes were assessed using intent-to-treat analysis. Retention was 97.1%. Both groups lost weight, with no significant differences between groups. At month 6, mean weight change was: intervention: -1.71 kg (SD 2.33; p = .006), 33.3% lost ≥3% of baseline weight; control: -2.54 kg (SD 4.00, p = .002), 23.5% lost ≥3% weight. Intervention participants achieved significant improvements in waist circumference (-3.56 cm, SD 4.70, p = .005), QOL (p = .030), and use of strategies for healthy eating (p = .025) and decreasing calories (p < .001). Number of days logged food per week was associated with decreases in waist circumference at 6 months (β -0.79, 95% CI, -1.49, -0.09, p = .030) and 12 months (β -2.16, 95% CI, -4.17, -0.15, p = .038). Weight loss was maintained at 12 months. This is the first study to demonstrate potential efficacy of commercial eHealth/mHealth tools for weight loss in AA BC survivors, without additional counseling from the research team. If effective, they may be convenient weight loss tools that can be easily and widely disseminated. Clinical Trials registration: ClinicalTrials.gov NCT02699983.
乳腺癌（BC）治疗后对非裔美国（AA）女性进行体重管理对于减少合并症和健康差距至关重要。我们研究了新泽西州 AA BC 幸存者使用商业电子健康/移动健康工具进行体重管理的可行性和潜在疗效。参与者（N = 35）被随机分配到干预组（SparkPeople）加活动追踪器，Fitbit Charge（n = 18）或等待名单对照组（仅 Fitbit，n = 17）。在基线、3、6 和 12 个月时收集了人体测量、行为和生活质量（QOL）结果。使用意向治疗分析评估了结果差异。保留率为 97.1%。两组体重均减轻，两组之间无显著差异。在 6 个月时，平均体重变化为：干预组：-1.71 公斤（SD 2.33；p =.006），33.3%的人减轻了基线体重的≥3%；对照组：-2.54 公斤（SD 4.00，p =.002），23.5%的人减轻了≥3%的体重。干预组在腰围（-3.56 厘米，SD 4.70，p =.005）、生活质量（p =.030）和健康饮食策略的使用（p =.025）和减少卡路里（p <.001）方面均有显著改善。每周记录食物天数与 6 个月时腰围减少相关（β-0.79，95%CI，-1.49，-0.09，p =.030）和 12 个月时（β-2.16，95%CI，-4.17，-0.15，p =.038）。体重在 12 个月时保持减轻。这是第一项证明商业电子健康/移动健康工具对 AA BC 幸存者减肥有效性的研究，而无需研究团队提供额外的咨询。如果有效，它们可能是方便的减肥工具，可以轻松广泛传播。临床试验注册：ClinicalTrials.gov NCT02699983。
