Greater numbers of women are entering young adulthood overweight, but traditional weight loss programs do not appeal to them. This article describes the development and evaluation of an e-health weight loss intervention for young women (18-30 years of age).
Young women's preferences for a targeted weight loss program were investigated via a cross-sectional online survey. A 3-month targeted weight loss program for young women was developed based on the formative research. A single-arm pre-post study was conducted to evaluate the acceptability of the intervention (process evaluation survey and objective usage data) and to estimate the treatments' effects on weight-related outcomes from baseline to 3 months.
Online survey respondents (n = 274) indicated preferences for various technologies (Web site, online quizzes with e-mail feedback and goal setting, an online discussion forum, smartphone application, e-mail newsletters, and text messages). Eighteen (mean ± standard deviation [SD] age, 22.8 ± 3.2 years; body mass index, 27.3 ± 1.6 kg/m(2)) women entered the pre-post study. Mean satisfaction was 3.4 ± 1.0 (maximum of 5), and 66.7% of participants completed the study. Significant reductions in mean ± SD weight (-1.5 ± 2.4 kg; p = 0.02) and waist circumference (-0.7 ± 1.4 cm; p = 0.04) were observed.
Due to lower than anticipated participant satisfaction, modifications to the program content and modes of delivery are required to ensure a higher proportion of young women complete and actively engage with the program. The positive effects of treatment on weight-related outcomes supports further refinement and evaluation of targeted, e-health weight loss interventions for young women.
越来越多的年轻女性进入成年期时体重超重，但传统的减肥项目对她们没有吸引力。本文描述了一项针对年轻女性（18 - 30岁）的电子健康减肥干预措施的开发与评估。
通过横断面在线调查研究年轻女性对有针对性的减肥项目的偏好。基于形成性研究开发了一个为期3个月的针对年轻女性的减肥项目。进行了一项单组前后对照研究，以评估干预措施的可接受性（过程评估调查和客观使用数据），并估计该治疗措施对从基线到3个月的体重相关结果的影响。
在线调查的受访者（n = 274）表明了对各种技术的偏好（网站、带有电子邮件反馈和目标设定的在线测验、在线讨论论坛、智能手机应用程序、电子邮件通讯和短信）。18名女性（平均年龄±标准差[SD]为22.8±3.2岁；体重指数为27.3±1.6kg/m²）进入了前后对照研究。平均满意度为3.4±1.0（满分5分），66.7%的参与者完成了研究。观察到平均体重±标准差显著下降（-1.5±2.4kg；p = 0.02），腰围下降（-0.7±1.4cm；p = 0.04）。
由于参与者满意度低于预期，需要对项目内容和交付方式进行修改，以确保更高比例的年轻女性完成并积极参与该项目。治疗对体重相关结果的积极影响支持对针对年轻女性的有针对性的电子健康减肥干预措施进行进一步优化和评估。
