研究目的:

本研究通过提供低膳食炎症指数(DII)饮食方案,并结合 DII 量化评估患者的膳食炎症潜力,制定个性化饮食干预策略,系统探究该饮食干预对患者疼痛体验的改善效果,最终为提升类风湿关节炎患者的生活质量提供科学依据与实践支撑。  

Objectives of Study:

This study systematically investigates the efficacy of personalized dietary intervention strategies in improving pain experience in patients with rheumatoid arthritis (RA) by providing a low-dietary-inflammation index (DII) diet plan, combined with DII quantification to assess dietary inflammatory potential, ultimately offering scientific evidence and practical support for enhancing the quality of life in RA patients.

干预措施:

Interventions:

组别:

A 组(对照组)

样本量:

53

Group:

Group A (Control group)

Sample size:

干预措施:

实施常规用药治疗 + 常规护理。选择首次确诊类风湿关节炎,接受慢作用抗风湿药(DMARDs)治疗>=3 个月,治疗方案稳定的患者;提供 RA 疾病知识、饮食、用药知识、关节保护指导等常规健康宣教,不提供饮食相关干预。

干预措施代码:

Intervention:

Conventional medication therapy + conventional nursing care. Patients with initial diagnosis of rheumatoid arthritis (RA) who have received disease-modifying antirheumatic drugs (DMARDs) for >=3 months and have stable treatment regimens were selected. The group received routine health education, including RA disease knowledge, dietary guidance, medication knowledge, and joint protection instructions, but no dietary interventions were provided.

Intervention code:

组别:

B 组(干预组)

样本量:

53

Group:

Group B (Intervention Group)

Sample size:

干预措施:

在对照组的基础上,增加基于膳食炎症指数(DII)的饮食干预。在临床营养师的指导下,提供低DII的饮食食谱,并根据基线 DII 结果制定个性化方案,使目标干预后 DII<=0;干预第 1-4 周每周 1 次线上指导(30 分钟 / 次),第 5-12 周每 2 周 1 次线上指导,定期收集患者24小时膳食记录,计算其DII,根据结果调整食谱;核心措施为增加深海鱼、深色蔬菜、全谷物摄入,限制红肉、精制糖及加工食品。

干预措施代码:

Intervention:

In addition to the control group, dietary intervention based on the Dietary Inflammation Index (DII) was implemented. Under the guidance of a clinical dietitian, low-DII dietary plans were provided, with personalized strategies tailored to baseline DII results to achieve a target post-intervention DII <=0. During weeks 1-4, online guidance was offered weekly (30 minutes per session), and from weeks 5-12, every two weeks. Regular collection of 24-hour dietary records was conducted to calculate DII, with plans adjusted accordingly. The core measures included increased intake of deep-sea fish, dark-colored vegetables, and whole grains, while limiting red meat, refined sugar, and processed foods.

随机方法(请说明由何人用什么方法产生随机序列):

采用随机数字表法按照 1:1 的比例随机分为两组。具体实施为使用 Excel 生成106个随机数字,一次读取 3 位数作为一个随机数录于编号下,然后将全部随机数字从小到大排序,规定序号 1~53 为对照组, 54~106为干预组。随后,将随机数字表密封在不透明信封中,交与第三人保管,信封经混合打乱后,在外部标注编号 1~106。根据入组顺序,依次拆封,从编号 1 开始,研究者依据信封内的分组数字对研究对象实施相应干预,并记录相关数据。

Randomization Procedure (please state who generates the random number sequence and by what method):

Participants were randomly assigned to two groups at a 1:1 ratio using a random number table. The procedure involved generating 106 random numbers in Excel, with three digits selected for each number to form a random identifier. All numbers were then ranked from smallest to largest, with numbers 1–53 designated as the control group and 54–106 as the intervention group. The sealed random number table was placed in an opaque envelope and entrusted to a third party for safekeeping. After being shuffled, the envelope was labeled with numbers 1–106. Researchers sequentially opened the envelopes starting from number 1, applying the assigned intervention based on the group number inside and recording relevant data.

是否公开试验完成后的统计结果:

Calculated Results after the Study Completed public access:

不公开/Private

盲法:

因试验过程中,干预人员和参与者会知道分组情况,故无法采用盲法,由一名不参与本研究的护士并进行量表评分,仅对数据收集和统计分析人员设盲。数据收集由独立的一名团队成员负责,收集者对研究对象的分组不知情

Blinding:

During the trial, the intervention personnel and participants would be aware of the grouping situation, so blinding could not be adopted. A nurse who did not participate in this study was assigned to score the scale, and only the data collection and statistical analysis personnel were blinded. Data collection was handled by an independent team member, who was unaware of the grouping of the research subjects
