Brief Summary:

The majority of the elderly present with sleep apnea and mortality is significantly higher in this group. Sleep apnea runs the risk of developing diseases, especially hypertension and cardiovascular disease, while the Mediterranean diet is associated with reduced risk.

No study evaluated the effect of the Mediterranean diet on the apnea and hypopnea index in the elderly. Therefore, the present work intends to evaluate the effect of the intervention with the Mediterranean diet on the apnea-hypopnea index in the elderly with moderate sleep apnea.

The hypothesis study is that the elderly with moderately severe sleep apnea under a Mediterranean-type diet will modify AHI in the short term, regardless of weight change, due to changes in body volume and ingestion, especially those related to body water.

Study Type : Interventional  (Clinical Trial)
Estimated Enrollment : 50 participants
Allocation: Randomized
Intervention Model: Parallel Assignment
Intervention Model Description: A randomized clinical trial will be conducted and the sample will consist of 50 participants who performed portable respiratory polysomnography. Cases with AHI between 15 and 50 events per hour will be sent for medical evaluation to identify inclusion/exclusion criteria. Eligible individuals who agree to participate in the study, after signing the Informed Consent Term, will perform physical, biochemical, questionnaire and randomized to receive guidelines on the Mediterranean-type diet or low-fat diet.

Arm Intervention/treatment
Experimental: Mediterranean-type diet
Recommends high consumption of whole grains, vegetables, nuts, fruits, vegetables and olive oil as the main source of fat used for salads. Moderate to high fish consumption and low consumption of red and processed meats. Poultry and dairy products (such as yogurt or cheese) will be consumed in small quantities and moderate consumption of alcohol, usually in the form of red wine, will be recommended with meals for usual drinkers.
Other: Mediterranean-type diet
Recommendations: ingest whole grains; three or more servings/day (various fresh fruits/vegetables); three or more servings/week of fish or seafood; white meat to red and processed meat (red meat to one serving or less/day); oilseed mix - 30g/day (nuts: 15g/day, almonds: 7.5g/day, hazelnuts: 7.5g/day); extra virgin olive oil (30ml/day: 2 soup spoons/day) as the main source of fat in the salads; two or more servings per week of "sofrito"; two servings/day of low-fat dairy products; limit to one serving/week the intake of fatty and cured cheeses; recommendation of 7 glasses per week of red wine (recommendation for habitual drinkers): 1 cup/day of 100ml for women and 1-2 cups/day of 150ml for men; limit to one serving/week the intake of chocolate with more than 50% cocoa.

Active Comparator: Low fat diet
It recommends reducing the intake of foods rich in fats, especially those saturated and hydrogenated.
Other: Low fat diet
Recommendations: choose grilled, cooked, baked or soaked preparations; avoid frying (sweet or salty); avoid excess fat in the preparations and season the foods with herbs at will (marjoram, basil, oregano, onion, green seasoning, sweet pepper, sage, etc.); avoid frequent ingestion of sausages such as ham, turkey breast, among others; avoid eating fatty meats and strip the skin of poultry before preparation; avoid eating sweets and fatty foods; avoid ingesting bakery products, such as leafy, tart, savory pasta.
