PURPOSE
This study evaluated the feasibility and preliminary efficacy of two 6-month, self-regulation interventions that focused on daily self-weighing (DSW) and used objective monitoring and tailored feedback about weight (±activity), to prevent weight gain among African American breast cancer survivors.
METHODS
Participants (n = 35) were randomized to an intervention + activity monitoring (INT+), intervention (INT), or control (CON) group. Interventions included a wireless scale (±activity tracker) that transmitted objective data to a mobile app/website, emailed lessons, and tailored feedback based on objective weight (±activity data). Participants completed in-person and online assessments at baseline, 3 months, and 6 months.
RESULTS
Ninety-four percent of participants completed assessments at 3 months, and 97 % at 6 months. Median (IQR) weight change after 6 months was -0.9 % (-4.4-0.1) in the INT+ (p = 0.075; p = 0.067 vs. CON) and -0.2 % (-4.2-1.3) in the INT groups (p = 0.463; p = 0.357 vs. CON), versus a 0.2 % (-0.7-1.7) gain in the CON group. The proportion of INT+, INT, and CON participants that were at or below baseline weight was 72.7, 53.8, and 45.5 %, respectively (effect sizes d = 0.64, d = 0.18). Most INT+ participants weighed and wore trackers ≥5 days/week (INT+, 81.9 % vs. INT, 38.5 % vs. CON, 0 %; p < 0.0005; INT+, 72.7 %). Both intervention groups perceived DSW as positive, and 100 % would recommend the program to other breast cancer survivors.
CONCLUSION
An intervention focused on DSW as a self-monitoring strategy shows promise for preventing weight gain in breast cancer survivors.
IMPLICATIONS FOR CANCER SURVIVORS
Daily self-monitoring of weight and activity may be a feasible and accessible approach to promote weight gain prevention in breast cancer survivors.

目的
本研究评估了两种为期6个月的自我调节干预措施的可行性和初步疗效，这两种干预措施侧重于每日自我称重（DSW），并利用客观监测和针对体重（±活动量）的个性化反馈，以预防非裔美国乳腺癌幸存者体重增加。
方法
参与者（n = 35）被随机分为干预+活动监测组（INT+）、干预组（INT）或对照组（CON）。干预措施包括一个无线秤（±活动追踪器），它将客观数据传输到移动应用程序/网站，通过电子邮件发送课程，并根据客观体重（±活动数据）提供个性化反馈。参与者在基线、3个月和6个月时完成了面对面和在线评估。
结果
94%的参与者在3个月时完成了评估，97%在6个月时完成了评估。INT+组6个月后的体重变化中位数（IQR）为-0.9%（-4.4-0.1）（p = 0.075；与CON组相比p = 0.067），INT组为-0.2%（-4.2-1.3）（p = 0.463；与CON组相比p = 0.357），而CON组体重增加了0.2%（-0.7-1.7）。体重处于或低于基线水平的INT+组、INT组和CON组参与者的比例分别为72.7%、53.8%和45.5%（效应大小d = 0.64，d = 0.18）。大多数INT+组参与者每周称重并佩戴追踪器≥5天（INT+组为81.9%，INT组为38.
