简介：科学证据表明，坚持地中海饮食可以防止衰老过程中认知状态和抑郁症状的恶化。然而，很少有研究已经进行了在老年人非制度化subjects.Objective：本研究评估了之间的关系，坚持地中海饮食模式和认知状态和抑郁症状的老年人口超过75 years.Methods：一个横断面研究进行了在地中海城市（Garrucha，西班牙）在79名老年人超过75（36名男性和41名女性）。使用地中海饮食依从性筛选器（Mediterranean Diet Adherence Screener，MEDAS）确定对地中海饮食模式的依从性。采用简易精神状态检查量表（MMSE）评定认知功能，采用老年抑郁量表（GDS）评定抑郁症状。他们食用橄榄油作为脂肪的主要来源，高水平的鱼类和水果，低水平的添加糖的食物，以及低水平的红肉消费。MEDAS与MMSE评分之间存在显著相关性，而与GDS评分之间无相关性。结论：地中海式饮食模式与认知功能呈正相关，但健康饮食模式对抑郁症认知功能的影响尚不清楚。然而，有效对抗认知功能和抑郁症的策略是提高身体活动率，建立终身健康的饮食习惯，并食用营养丰富的饮食，以提高老年人的生活质量。
Introduction: Scientific evidence indicates that adherence to the Mediterranean diet protects against the deterioration of cognitive status and depressive symptoms during aging. However, few studies have been conducted in elderly non-institutionalized subjects.Objective: This study evaluated the relation between the adherence to the Mediterranean dietary pattern and cognitive status and depressive symptoms in an elderly population over 75 years.Methods: A cross-sectional study was conducted in a Mediterranean city (Garrucha, Spain) in 79 elderly people over 75 (36 men and 41 women). Adherence to the Mediterranean dietary pattern was determined using the Mediterranean Diet Adherence Screener (MEDAS). Cognitive function was determined by the Mini Mental State Examination (MMSE), and depressive symptoms were assessed by the Geriatric Depression Scale (GDS).Results: Most of population showed a very high adherence to the Mediterranean diet pattern and optimal cognitive and affective status. They consumed olive oil as their main source of fat, high levels of fish and fruit, low levels of foods with added sugars, and a low consumption of red meat. A significant relation between the MEDAS and MMSE scores was found. However, no relationship was observed between the MEDAS and GDS.Conclusions: The Mediterranean diet pattern was positively related with the cognitive function, although the influence of a healthy dietary pattern on the symptomatology of depression was unclear. However, an effective strategy against cognitive function and depression would be to improve physical activity rates, establish lifelong healthy eating habits, and consume a nutritionally-rich diet in order to enhance quality of life of the elderly.
