Individual and group-based behavioral weight loss treatment (BWL) produces average weight loss of 5-10% of initial body weight, which improves health and wellbeing. However, BWL is an intensive treatment that is costly and not widely available. Smartphones may be a useful tool for promoting adherence to key aspects of BWL, such as self-monitoring, thereby facilitating weight loss while reducing the need for intensive in-person contact.
The objective of this study was to evaluate smartphones as a method of delivering key components of established and empirically validated behavioral weight loss treatment, with an emphasis on adherence to self-monitoring.
Twenty overweight/obese participants (95% women; 85% non-Hispanic White; mean age 53.0, SE 1.9) received 12-24 weeks of behavioral weight loss treatment consisting of smartphone-based self-monitoring, feedback, and behavioral skills training. Participants also received brief weekly weigh-ins and paper weight loss lessons.
Average weight loss was 8.4kg (SE 0.8kg; 9%, SE 1% of initial body weight) at 12 weeks and 10.9kg (SE 1.1kg; 11%, SE 1% of initial body weight) at 24 weeks. Adherence to the self-monitoring protocol was 91% (SE 3%) during the first 12 weeks and 85% (SE 4%) during the second 12 weeks.
Smartphones show promise as a tool for delivering key components of BWL and may be particularly advantageous for optimizing adherence to self-monitoring, a cornerstone of BWL.
个体和团体行为体重管理治疗（BWL）可使体重平均减轻初始体重的 5-10%，从而改善健康和幸福感。然而，BWL 是一种密集型治疗，费用高昂且不广泛适用。智能手机可能是促进 BWL 关键方面（如自我监测）依从性的有用工具，从而促进体重减轻，同时减少对密集面询的需求。
本研究旨在评估智能手机作为提供已建立和经验证的行为体重管理治疗的关键组成部分的方法，重点是关注自我监测的依从性。
20 名超重/肥胖参与者（95%女性；85%非西班牙裔白人；平均年龄 53.0，SE 1.9）接受 12-24 周的行为体重管理治疗，包括基于智能手机的自我监测、反馈和行为技能培训。参与者还接受了简短的每周称重和纸质体重管理课程。
12 周时的平均体重减轻为 8.4kg（SE 0.8kg；9%，SE 1%的初始体重），24 周时为 10.9kg（SE 1.1kg；11%，SE 1%的初始体重）。在最初的 12 周内，自我监测方案的依从性为 91%（SE 3%），在接下来的 12 周内为 85%（SE 4%）。
智能手机作为 BWL 关键组成部分的提供工具显示出一定的前景，对于优化自我监测的依从性（BWL 的基石）可能特别有利。
