Some questions regarding the benefits of the Mediterranean Dietary Pattern (MDP) are still unanswered, especially in non-Mediterranean areas. As such, this study intends to evaluate the association between the adherence to the MDP with the presence of Common Mental Disorders (CMD) in Brazilian older adults, adopting two different concepts of MDP.
The sample included 545 elders from 2015 Health Survey of São Paulo City (cross-sectional population-based study). CMD were identified through the Self Reporting Questionnaire-20 (SRQ-20). Data from two 24-hour dietary recall were used to construct two concepts of MDP according to the Mediterranean-diet score (MDS): Traditional MDP (included only foods with characteristics of the original MDP) and Brazilian-MDP (included foods with non-Mediterranean characteristics). The analyses included two different models (crude model and adjusted model for potential confounders) of logistic regression.
Moderate and high adherence to Traditional MDP were associated with a lower prevalence of CMD (OR: 0.59; 95% CI: 0.35-0.98 and OR: 0.42, 95% CI: 0.18-0.96, respectively), after adjustment for sociodemographic, lifestyle and health status variables. In turn, the presence of CMD was not significantly associated with any level of adherence to the Brazilian-MDP.
due to the cross-sectional feature of the study, we cannot determine a cause-effect relationship; some covariates were self-reported; the results cannot apply to the elderly from other regions.
Moderate and high adherence to the traditional MDP was found to reduce the risk of mental disorders in Brazilian elderly. Nevertheless, an increased intake of non-Mediterranean food components can limit this effect.
地中海饮食模式（MDP）的益处仍存在一些未解之谜，尤其是在非地中海地区。因此，本研究旨在评估巴西老年人中 MDP 依从性与常见精神障碍（CMD）之间的关联，并采用两种不同的 MDP 概念。
该样本包括来自 2015 年圣保罗市健康调查的 545 名老年人（横断面人群研究）。CMD 通过自我报告问卷-20（SRQ-20）进行识别。使用两次 24 小时膳食回忆的数据，根据地中海饮食评分（MDS）构建了两种 MDP 概念：传统 MDP（仅包含具有原始 MDP 特征的食物）和巴西 MDP（包含具有非地中海特征的食物）。分析包括两种不同的逻辑回归模型（未调整和调整潜在混杂因素的模型）。
传统 MDP 中度和高度依从性与 CMD 的低患病率相关（OR：0.59；95%CI：0.35-0.98 和 OR：0.42，95%CI：0.18-0.96，分别），调整了社会人口统计学、生活方式和健康状况变量后。相反，CMD 的存在与巴西 MDP 任何依从水平均无显著相关性。
由于研究的横断面特征，我们无法确定因果关系；一些协变量是自我报告的；研究结果不适用于其他地区的老年人。
中度和高度依从传统 MDP 可降低巴西老年人患精神障碍的风险。然而，增加非地中海食物成分的摄入可能会限制这种效果。
