Obesity is among the most significant health challenges facing today's adolescents. Weight gain during adolescence is related to cardiovascular disease, type 2 diabetes, and some cancers in later life. Presently, adolescents living in Australia have limited access to age-appropriate obesity prevention services.
This study aims to investigate whether a two-way text message program, with optional telephone health counseling, improves body mass index (BMI) z score and lifestyle outcomes in adolescents who are overweight.
This study will be a single-blind randomized controlled trial (N=150) comparing a two-way text message intervention, with optional telephone health counseling, to usual care in adolescents (13-18 years old, inclusive) who are overweight (recruited from a pediatric weight management clinic and the broader community in Sydney, Australia). The intervention group will receive a six-month text message program, which consists of two-way, semipersonalized, lifestyle-focused text messages (four messages/week) in addition to usual care. The control group will be assigned to receive usual care. The study also includes a follow-up at 12-months. The primary outcome is a change in BMI z score at six months. Secondary outcomes are changes in waist-to-height ratio, diet, physical and sedentary activity levels, sleep quality, quality of life, self-esteem, self-efficacy, social support, and eating disorder and depression symptoms. Also, we will examine acceptability, utility, and engagement with the program through a study-specific process evaluation questionnaire, semi-structured telephone interviews, and an analysis of health counselor communication logs. The analyses will be performed by the intention-to-treat principle to assess differences between intervention and control groups.
The study opened for recruitment in December 2019. Data collection is expected to be completed by December 2021, and the results for the primary outcome are expected to be published in early 2022.
This study will test the effectiveness of an interactive two-way text message program compared to usual care in improving BMI z score and lifestyle outcomes in adolescents with overweight. This interactive, innovative, and scalable project also aims to inform future practice and community initiatives to promote obesity prevention behaviors for adolescents.

肥胖是当今青少年面临的最重大健康挑战之一。青少年时期体重增加与心血管疾病、2型糖尿病以及日后的某些癌症有关。目前，生活在澳大利亚的青少年获得适合其年龄的肥胖预防服务的机会有限。
本研究旨在调查一项双向短信计划（可选择电话健康咨询）是否能改善超重青少年的体重指数（BMI）z评分和生活方式相关结果。
本研究将是一项单盲随机对照试验（N = 150），将一项双向短信干预（可选择电话健康咨询）与超重青少年（13至18岁，包括13岁和18岁）的常规护理进行比较（从澳大利亚悉尼的一家儿科体重管理诊所和更广泛的社区招募）。干预组将接受为期六个月的短信计划，除常规护理外，该计划包括双向、半个性化、以生活方式为重点的短信（每周四条短信）。对照组将被分配接受常规护理。该研究还包括12个月的随访。主要结局是六个月时BMI z评分的变化。次要结局包括腰高比、饮食、身体活动和久坐活动水平、睡眠质量、生活质量、自尊、自我效能感、社会支持以及饮食失调和抑郁症状的变化。此外，我们将通过一份特定研究的过程评估问卷、半结构化电话访谈以及对健康顾问沟通记录的分析，来考察该计划的可接受性、实用性和参与度。分析将按照意向性分析原则进行，以评估干预组和对照组之间的差异。
该研究于2019年12月开始招募。预计数据收集将于2021年12月完成，主要结局的结果预计于2022年初发表。
本研究将测试一项交互式双向短信计划与常规护理相比，在改善超重青少年的BMI z评分和生活方式相关结果方面的有效性。这个交互式、创新性且可扩展的项目还旨在为未来的实践和社区倡议提供信息，以促进青少年的肥胖预防行为。
