干预措施:

依据受试者的肥胖风险及体育健身行为特征,结合助推理论制定按肥胖风险分层的助推干预方案。干预组受试者在12周的干预周期内每周的周一至五在校时间段佩戴运动手环(小米Redmi3)。低风险受试者接受以下类型的助推干预:1.环境线索助推(张贴促进体育健身行为的海报与提示语);2.反馈助推(定期反馈运动手环数据报告);3.同辈比较助推(定期反馈受试者其活动水平在干预组内的排名情况)。中高风险受试者接受以下类型助推干预:1.提醒助推(手环发送的久坐打断提示语信息);2.环境线索助推(张贴促进体育健身行为的海报与提示语);3.反馈助推(定期反馈运动手环数据报告);4.框架助推(告知受试者特定行为的获益与损失);5.同辈比较助推(定期反馈受试者其活动水平在干预组内的排名情况);6.预承诺助推(与受试者沟通,受试者预承诺每日步数活动目标)。

干预措施代码:

Intervention:

Based on participants' obesity risk and physical fitness behavior characteristics, an obesity-risk-stratified nudge intervention program was developed in accordance with nudge theory. Participants in the intervention group wore a fitness tracker (Xiaomi Redmi 3) during school hours from Monday to Friday throughout the 12-week intervention period. Low-risk participants received the following nudge interventions: (1) environmental cue nudges (posters and prompts promoting physical fitness behavior); (2) feedback nudges (regular feedback reports on fitness tracker data); and (3) peer comparison nudges (regular feedback on participants' activity level rankings within the intervention group). Moderate- and high-risk participants received the following nudge interventions: 1. reminder nudges (sedentary break prompt messages delivered via the fitness tracker); 2. environmental cue nudges (posters and prompts promoting physical fitness behavior); 3. feedback nudges (regular feedback reports on fitness tracker data); 4. framing nudges (informing participants of the benefits and losses associated with specific behaviors); 5. peer comparison nudges (regular feedback on participants' activity level rankings within the intervention group); and 6. pre-commitment nudges (discussing and establishing daily step activity goals with participants through pre-commitment).
