Depression is a very common disorder in elderly, especially in those institutionalized. Nutrition could play an important role in the onset and/or progression of depression, since the intake of carbohydrates with a high glycaemic index (GI) or diets with a high glycaemic load (GL) may increase the insulin-induced brain serotonin secretion. %26lt;br%26gt;The aim of our study was to analyse the association between dietary GI and GL and the odds of suffering depression in institutionalized elderly people without antidepressant treatment. %26lt;br%26gt;This cross-sectional study included 140 institutionalized elderly people from the Madrid region (Spain) (65-90 years of age) whose diets were recorded using a precise weighing method over seven consecutive days. Energy and nutrient intakes were recorded and the GI and GL calculated. The participants%26apos; affective capacity was assessed using the Geriatric Depression Scale (GDS). Subjects were grouped into non-depressed (GDS a parts per thousand currency sign 5) and depressed (GDS %26gt; 5). Since GDS scores and gender were statistically associated (p %26lt; 0.01), the data were grouped considering this association. %26lt;br%26gt;Dietary GI (51.09 +/- A 3.80) and GL (97.54 +/- A 13.46) were considered as medium. The dietary GL was significantly higher in the non-depressed (100.00 +/- A 12.13) compared with the depressed group (93.97 +/- A 14.04, p %26lt; 0.01). However, a similar GI was observed between non-depressed (51.50 +/- A 3.29) and depressed groups (50.52 +/- A 4.46). Additionally, participants with a dietary GL placed in the second and third tertiles had a 67.4 % and 65.3 %, respectively, less odds of suffering depression than those in the first tertile. GDS scores and dietary GL were inversely related; therefore, an increase in one unit in the dietary GL scale decreased the GDS score by 0.058 units. %26lt;br%26gt;Glyaemic load is associated with a lower odd of depression.
