研究目的: |
本研究旨在评估一项基于社区卫生服务中心实施的,结合运动行为干预与支付模式创新的综合性减重项目的有效性与可推广性。该项目通过整合运动干预、行为指导、健康教育与个体化管理,旨在提升社区超重及肥胖人群对科学减重与体重维持的认知水平,促进其形成健康、主动的生活方式与自我管理行为,从而改善体重控制相关健康结局。同时,本研究将系统比较不同运动干预时长及不同支付模式(免费、医保报销)在改善体重管理效果与提高干预依从性方面的差异。通过引入健康经济学评价,进一步探讨并识别最具成本效益、可持续推广的干预组合模式,为社区层面慢性病防控及健康促进提供可行的政策建议与实践依据。 |

Objectives of Study: |
This study aims to evaluate the effectiveness and scalability of a comprehensive weight loss program implemented through community health service centers, integrating exercise behavior interventions with innovative payment models. By combining exercise interventions, behavioral guidance, health education, and personalized management, the program seeks to enhance overweight and obese community members' understanding of scientific weight loss and maintenance. It promotes the adoption of healthy, proactive lifestyles and self-management behaviors, thereby improving health outcomes related to weight control. Concurrently, this study will systematically compare differences in weight management outcomes and intervention adherence across varying exercise intervention durations and payment models (free vs. medical insurance reimbursement). By incorporating health economics evaluation, it further explores and identifies the most cost-effective and sustainably scalable intervention combination, providing actionable policy recommendations and practical evidence for chronic disease prevention and health promotion at the community level. |

随机方法(请说明由何人用什么方法产生随机序列): |
本研究采用个体水平的分层随机化(Stratified randomization at the individual level)的方式,将符合纳排条准的研究对象按1:1:1:1比例随机化方案分配至 4 个干预组。为保证分组间基线特征的均衡性,同时适配“付费意愿”的实际参与场景。首先根据研究对象的基线体质指数(body mass index, BMI)水平(<28 kg/m^2 与 >=28 kg/m^2),付费意愿(仅接受免费参与 vs 愿意接受付费参与)进行分层随机。在确认参与意愿后及完成基线评估后,由一名未参与试验实施和结果评估的独立工作人员(GX)负责随机化过程。该人员使用 R 软件中的 “sampling” 包的“strata”函数,以“付费意愿、BMI 分层” 为分层变量,按无放回简单随机抽样(method = "srswor")原则实施分层随机抽样,生成个体层面的随机分配序列(研究对象均赋予唯一编号)。随后,GX 根据随机化结果,将研究对象随机分配至 4 个干预组中,并完成最终的分组名单整理。 |

|
Randomization Procedure (please state who generates the random number sequence and by what method): |
This study adopted the stratified randomization at the individual level approach, allocating the eligible research subjects according to a 1:1:1:1 randomization scheme to 4 intervention groups. To ensure the balance of baseline characteristics among the groups and to adapt to the actual participation scenario of "willingness to pay", the stratified randomization was conducted first based on the baseline body mass index (BMI) level of the research subjects (< 28 kg/m^2 and >= 28 kg/m^2) and the willingness to pay (only accepting free participation vs willing to accept paid participation). After confirming the willingness to participate and completing the baseline assessment, an independent staff member (GX) who was not involved in the trial implementation and result evaluation was responsible for the randomization process. This person used the "sampling" package in R software's "strata" function, with "willingness to pay and BMI stratification" as the stratification variables, to implement stratified random sampling without replacement (method = "srswor") according to the principle of simple random sampling without replacement (method = "srswor"), generating the random allocation sequence at the individual level (each research subject was assigned a unique number). Subsequently, GX randomly assigned the research subjects to the 4 intervention groups based on the randomization results and completed the final grouping list compilation. |

盲法: |
本研究采用评估者与数据分析者双盲(assessor- and analyst-blind)设计。由于干预措施的性质不同(干预强度及支付模式存在显著差异),参与者与执行干预的社区健康管理人员无法完全实现盲法。但为最大限度降低偏倚,研究在以下方面实施严格的盲法管理措施。包括分配隐蔽(Allocation Concealment),研究对象在基线评估完成后,由一名未参与干预和评估的独立研究助理使用随机化程序完成分组。分配结果以加密形式保存,仅项目协调员和干预实施者可见,评估人员、数据录入人员及统计分析人员在整个过程中均未知组别信息。评估者盲法(Assessor Blinding),所有物理指标如体重、体脂、腰围、臀围及代谢指标等客观数据均由经过统一培训且未参与干预执行的评估人员独立测量。评估现场不透露受试者干预类型,确保评估过程的客观性。数据分析盲法(Data Analyst Blinding),数据在录入与分析阶段将采用编码化管理,不显示干预组别名称。统计分析由独立数据分析师完成,仅在主要统计分析结束后才进行盲态揭盲。盲法保持与揭盲(Blinding Maintenance and Unblinding),在整个干预与随访期间,研究组别信息均不向评估与分析人员公开。 |
|
Blinding: |
This study employed a double-blind design for both assessors and data analysts. Due to the differing nature of the interventions (significant variations in intervention intensity and payment models), complete blinding of participants and the community health workers delivering the interventions could not be achieved. However, to minimize bias, strict blinding management measures were implemented in the following areas: Allocation Concealment: After completing baseline assessments, participants were randomly assigned to groups by an independent research assistant not involved in the intervention or evaluation, using a randomized procedure. Allocation results were stored in encrypted form, accessible only to the project coordinator and intervention implementers. Evaluators, data entry personnel, and statistical analysts remained unaware of group assignments throughout the process. Assessor blinding ensured that all physical measurements—including weight, body fat, waist circumference, hip circumference, and metabolic indicators—were independently recorded by uniformly trained evaluators not involved in intervention delivery. Intervention type was concealed at assessment sites to ensure objectivity. Data Analyst Blinding: Data underwent coded management during entry and analysis, with intervention group names concealed. Statistical analysis was conducted by independent data analysts, with blinding maintained until primary analyses were completed. Blinding Maintenance and Unblinding: Throughout the intervention and follow-up periods, study group information remained concealed from evaluators and analysts. Limited unblinding was permitted only for urgent handling of Serious Adverse Events (SAEs), subject to approval by the Principal Investigator, with all unblinding instances documented. |
