Maintaining weight loss results in childhood obesity treatment is difficult to achieve. Self-management techniques such as self-monitoring are associated with increased weight loss and maintenance. This study analyzes whether self-monitoring of lifestyle behaviours through a short message service maintenance treatment (SMSMT) via mobile phones with personalized feedback positively effects weight, lifestyle behaviours and psychological well-being in obese children.
After 3 months of behavioural lifestyle treatment, 141 overweight and obese children (7-12 years) were randomly assigned to an intervention group receiving SMSMT for 9 months (n = 73) or to the control group (n = 68). The intervention group sent weekly self-monitoring data on exercise and eating behaviour and their mood via mobile phones. In return, they received tailored feedback messages. Primary treatment outcomes were weight, eating behaviour and psychological well-being, i.e. competence, self-esteem and quality of life. Secondary outcome was adherence to the SMSMT. Data were analyzed with mixed modelling.
SMSMT did not improve treatment outcomes. Controls gained temporarily in physical health scores (P = 0.01). SMSMT completers sent on average every 2 weeks an SMS. Children who had greater weight loss during the first 3 months of lifestyle treatment sent more SMSs (P = 0.04).
We did not find a positive effect of SMSMT on weight, eating behaviour or psychological well-being in obese children. SMSMT seems to be a feasible method of treatment delivery. Future research should study variations of SMSMT to investigate how SMSMT can be more effective.
在儿童肥胖治疗中维持体重减轻的效果很难实现。自我监测等自我管理技巧与体重减轻及维持体重增加相关。本研究分析通过手机短信服务维持治疗（SMSMT）对生活方式行为进行自我监测并给予个性化反馈是否能对肥胖儿童的体重、生活方式行为及心理健康产生积极影响。
在进行3个月的行为生活方式治疗后，141名超重和肥胖儿童（7至12岁）被随机分为干预组（n = 73）和对照组（n = 68），干预组接受为期9个月的SMSMT。干预组通过手机每周发送关于运动、饮食行为及情绪的自我监测数据。作为回报，他们收到量身定制的反馈信息。主要治疗结果是体重、饮食行为及心理健康，即能力、自尊和生活质量。次要结果是对SMSMT的依从性。采用混合模型分析数据。
SMSMT未改善治疗结果。对照组的身体健康得分暂时增加（P = 0.01）。SMSMT的完成者平均每2周发送一条短信。在生活方式治疗的前3个月体重减轻更多的儿童发送的短信更多（P = 0.04）。
我们未发现SMSMT对肥胖儿童的体重、饮食行为或心理健康有积极影响。SMSMT似乎是一种可行的治疗方式。未来的研究应探讨SMSMT的变化形式，以研究如何能使SMSMT更有效。
