Abstract

Objective: The aim of this study was to assess the association between adherence to Mediterranean diet and the presence of atrial fibrillation (AF) in a Northern Chinese population.

Methods: This study was a single center, case-control study. A total of 952 low risk participants in Beijing Anzhen Hospital from 2016 to 2021 were collected, including 476 patients with first diagnosed of atrial fibrillation and 476 age and sex matched controls. According to the food frequency questionnaire (FFQ), the alternate Mediterranean diet score (AMED) was calculated, which was 0-9 points, indicating the adherence to the Mediterranean diet from low to high.

Results: The average age of the participants was 57.6 ± 9.1 years old, and 70.2% were men. After analyzing every component of AMED, vegetable consumption shows a negative correlation with the risk of AF, whereas alcohol consumption demonstrates a positive correlation with it (OR = 0.61, 95% CI 0.44-0.80, p < 0.001; OR = 1.99, 95% CI 1.48-2.58, p < 0.001). All patients were grouped according to AMED score. A significant inverse association between AMED and the risk of AF was observed. Compared with participants with AMED<4, the multivariable-adjusted ORs of AF were 0.75 (95% CI 0.55-1.06) for AMED 4-5 and 0.61 (95% CI 0.43-0.89) for AMED ≥6, with a trend in risk (p = 0.008). Results were consistent in stratified analyses of gender, age, BMI and smoking.

Conclusion: The Mediterranean diet was inversely associated with the risk of AF in this Northern Chinese population.

地中海饮食与心房颤动：一项来自中国的病例对照研究。

研究目的本研究旨在评估在中国北方人群中坚持地中海饮食与心房颤动（房颤）之间的关系：本研究为单中心病例对照研究。方法：本研究为单中心病例对照研究，收集了2016年至2021年北京安贞医院的952名低风险参与者，包括476名首次诊断为心房颤动的患者和476名年龄和性别匹配的对照者。根据食物频率问卷（FFQ），计算出备用地中海饮食评分（AMED），该评分为0-9分，由低到高表示对地中海饮食的坚持程度：参与者的平均年龄为（57.6±9.1）岁，70.2%为男性。在分析了地中海饮食的各个组成部分后，蔬菜摄入量与房颤风险呈负相关，而酒精摄入量与房颤风险呈正相关（OR = 0.61，95% CI 0.44-0.80，p p = 0.008）。在对性别、年龄、体重指数和吸烟进行分层分析后，结果一致：结论：在中国北方人群中，地中海饮食与房颤风险成反比。

期刊介绍： No subject pertains more to human life than nutrition. The aim of Frontiers in Nutrition is to integrate major scientific disciplines in this vast field in order to address the most relevant and pertinent questions and developments. Our ambition is to create an integrated podium based on original research, clinical trials, and contemporary reviews to build a reputable knowledge forum in the domains of human health, dietary behaviors, agronomy & 21st century food science. Through the recognized open-access Frontiers platform we welcome manuscripts to our dedicated sections relating to different areas in the field of nutrition with a focus on human health. Specialty sections in Frontiers in Nutrition include, for example, Clinical Nutrition, Nutrition & Sustainable Diets, Nutrition and Food Science Technology, Nutrition Methodology, Sport & Exercise Nutrition, Food Chemistry, and Nutritional Immunology. Based on the publication of rigorous scientific research, we thrive to achieve a visible impact on the global nutrition agenda addressing the grand challenges of our time, including obesity, malnutrition, hunger, food waste, sustainability and consumer health.
