Abstract

Background: No study has been conducted to investigate the association between adherence to the EAT-Lancet diet and odds of irritable bowel syndrome (IBS) and functional dyspepsia (FD). This cross-sectional study was aimed to assess the association between adherence to the EAT-Lancet diet and odds of IBS and FD.

Methods: This cross-sectional analysis was done among 1892 Iranian apparently healthy adults, aged 18 to 65 years, in Isfahan, Iran. Usual dietary intakes of participants were assessed using a validated Dish-based, 106-item food frequency questionnaire. To measure participants' adherence to the EAT-Lancet diet, the EAT-Lancet diet index (ELD-I) was calculated. IBS and FD were assessed using ROME IV criteria.

Results: In total, 5.29% and 3.17% of participants had IBS and FD, respectively. The mean age of study participants was 39.64 ± 10.24 years, and the mean BMI was 27.08 ± 4.91 kg/m². After adjustment for potential confounding factors, a significant positive association between lower adherence to the EAT-Lancet diet and odds of IBS was revealed (OR: 1.74; 95% CI: 1.00-3.04), but not for FD (OR: 1.37; 95% CI: 0.65-2.89).

Conclusion: A significant positive association was observed between lower adherence to EAT-Lancet diet and odds of IBS. More prospective studies are needed to affirm these associations.

坚持EAT-Lancet饮食与肠易激综合征和功能性消化不良的几率：伊斯法罕功能障碍（ISFUN）研究

背景：没有研究调查坚持EAT-Lancet饮食与肠易激综合征（IBS）和功能性消化不良（FD）发生率之间的关系。这项横断面研究旨在评估坚持EAT-Lancet饮食与肠易激综合征和FD发生率之间的关系。方法：对伊朗伊斯法罕地区1892名年龄在18至65岁之间明显健康的成年人进行了横断面分析。参与者的日常饮食摄入量是用一份经过验证的基于菜肴的106项食物频率问卷来评估的。为了衡量参与者对EAT-Lancet饮食的坚持程度，计算了EAT-Lancet饮食指数（ELD-I）。IBS和FD采用ROME IV标准进行评估。结果：共有5.29%和3.17%的参与者患有IBS和FD。研究参与者的平均年龄为39.64±10.24岁，平均BMI为27.08±4.91 kg/m²。在对潜在的混杂因素进行校正后，发现较低的EAT-Lancet饮食依从性与IBS发生率之间存在显著的正相关（OR: 1.74; 95% CI: 1.00-3.04），但与FD无关（OR: 1.37; 95% CI: 0.65-2.89）。结论：较低的EAT-Lancet饮食依从性与肠易激综合征的发生率之间存在显著的正相关。需要更多的前瞻性研究来证实这些关联。

期刊介绍： Nutrition Journal publishes surveillance, epidemiologic, and intervention research that sheds light on i) influences (e.g., familial, environmental) on eating patterns; ii) associations between eating patterns and health, and iii) strategies to improve eating patterns among populations. The journal also welcomes manuscripts reporting on the psychometric properties (e.g., validity, reliability) and feasibility of methods (e.g., for assessing dietary intake) for human nutrition research. In addition, study protocols for controlled trials and cohort studies, with an emphasis on methods for assessing dietary exposures and outcomes as well as intervention components, will be considered. Manuscripts that consider eating patterns holistically, as opposed to solely reductionist approaches that focus on specific dietary components in isolation, are encouraged. Also encouraged are papers that take a holistic or systems perspective in attempting to understand possible compensatory and differential effects of nutrition interventions. The journal does not consider animal studies. In addition to the influence of eating patterns for human health, we also invite research providing insights into the environmental sustainability of dietary practices. Again, a holistic perspective is encouraged, for example, through the consideration of how eating patterns might maximize both human and planetary health.
