BACKGROUND Dietary patterns and their association with subsequent clinical course have not been well studied in early multiple sclerosis (MS). OBJECTIVES To describe dietary patterns in people in 5 years following first clinical demyelination and assess associations with MS conversion and relapse. METHODS This study included baseline food frequency questionnaire dietary intake (entry to the Ausimmune Study) and 5-year follow-up; iterated principal factor analysis was applied. MS conversion and relapse risks were assessed by Cox proportional hazards models, adjusted for age, sex, study site, education, body mass index (BMI), smoking and omega-3 supplement use. RESULTS In cases with a first clinical diagnosis of central nervous system (CNS) demyelination, we identified three major dietary patterns, 'Prudent', 'High-Vegetable' and 'Mixed', explaining 43%, 37% and 24% of diet variance in dietary intake, respectively. Fruits, vegetables, fish, wholegrains and nuts loaded highly on the Prudent pattern, starchy vegetables and legumes on the High-Vegetable pattern, and meats and alcohol on the Mixed pattern. Diet factor scores were not associated with MS conversion risk. Those with baseline Prudent scores above the median had significantly lower relapse risk (adjusted hazard ratio = 0.54, 95% confidence interval (CI) 0.37, 0.81) with some evidence of a plateau effect. CONCLUSION Prudent diet factor score above the median was prospectively associated with lower relapse risk in the 5 years following the first clinical demyelinating event.

高谨慎饮食因素评分预测早期多发性硬化症复发风险较低

背景 早期多发性硬化症 (MS) 中的饮食模式及其与随后的临床病程的关联尚未得到很好的研究。目的 描述首次临床脱髓鞘后 5 年内人们的饮食模式,并评估与 MS 转化和复发的关联。方法 本研究包括基线食物频率问卷饮食摄入量(参加 Asimmune 研究)和 5 年随访;应用迭代主因子分析。MS 转化和复发风险通过 Cox 比例风险模型评估,根据年龄、性别、研究地点、教育、体重指数 (BMI)、吸烟和 omega-3 补充剂的使用进行调整。结果 在首次临床诊断为中枢神经系统 (CNS) 脱髓鞘的病例中,我们确定了三种主要的饮食模式,“谨慎”、“高蔬菜” 和“混合”,分别解释了饮食摄入量的 43%、37% 和 24% 的饮食差异。水果、蔬菜、鱼、全麦和坚果属于谨慎模式,淀粉类蔬菜和豆类属于高蔬菜模式,肉类和酒精属于混合模式。饮食因素评分与 MS 转换风险无关。基线审慎评分高于中位数的患者复发风险显着降低(调整后的风险比 = 0.54,95% 置信区间 (CI) 0.37, 0.81),并有一些平台效应的证据。结论 高于中位数的谨慎饮食因素评分与首次临床脱髓鞘事件后 5 年内较低的复发风险相关。全麦和坚果在谨慎模式中含量很高,淀粉类蔬菜和豆类在高蔬菜模式中,肉类和酒精在混合模式中。饮食因素评分与 MS 转换风险无关。基线谨慎评分高于中位数的患者复发风险显着降低(调整后的风险比 = 0.54,95% 置信区间 (CI) 0.37、0.81),并有一些平台效应的证据。结论 高于中位数的谨慎饮食因素评分与首次临床脱髓鞘事件后 5 年内较低的复发风险相关。全麦和坚果在谨慎模式中含量很高,淀粉类蔬菜和豆类在高蔬菜模式中,肉类和酒精在混合模式中。饮食因素评分与 MS 转换风险无关。基线审慎评分高于中位数的患者复发风险显着降低(调整后的风险比 = 0.54,95% 置信区间 (CI) 0.37, 0.81),并有一些平台效应的证据。结论 高于中位数的谨慎饮食因素评分与首次临床脱髓鞘事件后 5 年内较低的复发风险相关。基线谨慎评分高于中位数的患者复发风险显着降低(调整后的风险比 = 0.54,95% 置信区间 (CI) 0.37、0.81),并有一些平台效应的证据。结论 高于中位数的谨慎饮食因素评分与首次临床脱髓鞘事件后 5 年内较低的复发风险相关。基线审慎评分高于中位数的患者复发风险显着降低(调整后的风险比 = 0.54,95% 置信区间 (CI) 0.37, 0.81),并有一些平台效应的证据。结论 高于中位数的谨慎饮食因素评分与首次临床脱髓鞘事件后 5 年内较低的复发风险相关。
