Abstract

BACKGROUND

The ActWELL randomised controlled trial assessed the effectiveness of a weight management programme delivered by volunteer lifestyle coaches (LCs) in women attending breast clinics. The intervention focused on caloric intake and physical activity, utilising behavioural change techniques including a weight awareness plan (WAP). The current work is a secondary analysis of the ActWELL data and aims to examine the response to the weight self-awareness plan (used as part of the intervention programme).

METHODS

The LCs invited participants (n = 279) to undertake an implementation intention discussion to formulate a self-weighing (SW) plan. Bodyweight scales were offered, and recording books provided. The physical activity component of the intervention focused on a walking plan assessed by accelerometers. The LCs contacted participants by telephone monthly and provided personalised feedback. Mann-Whitney tests and chi-squared analysis were used to examine the effect of SW on weight change. A qualitative evaluation utilising semi-structured interviews was also undertaken.

RESULTS

Most participants (96.4%) agreed to set a weekly SW goal and 76 (27%) requested scales. At 12 months, 226 (81%) returned for follow up. The median (interquartile range) weight change for those who self- reported at least one weight (n = 211) was -2.3 kg (-5.0 to 0.0) compared to -1.2 kg (-5.0 to 0.03) in those who did not (n = 14). Participants who reported weights on more than eight occasions (39%) were significantly more likely (p = 0.012) to achieve 5% weight loss compared to those who weighed less often. Low numbers of accelerometers were returned that did not allow for significance testing. Qualitative data (n = 24) indicated that many participants found the WAP helpful and motivating.

CONCLUSIONS

Greater adherence to the WAP initiated by volunteer coaches is associated with achieving 5% weight loss.

摘要

背景

ActWELL 随机对照试验评估了由志愿者生活教练（LC）在参加乳腺诊所的女性中提供的体重管理计划的有效性。该干预措施侧重于热量摄入和身体活动，利用行为改变技术，包括体重意识计划（WAP）。目前的工作是对 ActWELL 数据的二次分析，旨在检查对体重自我意识计划（用作干预计划的一部分）的反应。

方法

LC 邀请参与者（n=279）进行实施意图讨论，制定自我称重（SW）计划。提供体重秤和记录簿。干预的身体活动部分侧重于通过加速度计评估的步行计划。LC 通过电话每月与参与者联系，并提供个性化反馈。使用 Mann-Whitney 检验和卡方分析检查 SW 对体重变化的影响。还利用半结构化访谈进行了定性评估。

结果

大多数参与者（96.4%）同意设定每周 SW 目标，其中 76 人（27%）要求提供秤。在 12 个月时，226 人（81%）返回进行随访。至少报告一次体重的参与者（n=211）的体重中位数（四分位距）变化为-2.3kg（-5.0 至 0.0），而未报告体重的参与者（n=14）为-1.2kg（-5.0 至 0.03）。报告体重超过八次（39%）的参与者更有可能（p=0.012）实现 5%的体重减轻，而体重减轻较少的参与者则无统计学意义。返回的加速度计数量很少，无法进行显著性检验。定性数据（n=24）表明，许多参与者发现 WAP 很有帮助和激励作用。
