Brief Summary

Introduction. Worldwide, obstructive sleep apnea is estimated to affect one in seven individuals. Patients with OSA present chronic low-grade inflammation related to arteriosclerosis. The effect of the Mediterranean diet on metabolic risk indicators is still inconclusive in the OSA population. Objective: To evaluate the effect of a Mediterranean diet adapted to the Mexican diet, versus standard nutritional treatment, on metabolic risk indicators in patients with obstructive sleep apnea. Material and methods: Randomized clinical trial in patients with OSA confirmed by polysomnography. Sociodemographic data, pathological and non-pathological history, as well as clinical data will be collected by interview. Patients will be randomly assigned to the group with personalized Mediterranean-type diet adapted to the Mexican diet or standard diet for patients with OSA. At baseline, 6 and 12 months with the patient fasting, glucose levels and lipid profile in venous blood will be measured, as well as carotid artery thickness. Anthropometry and body composition measurements will also be taken, in addition to questionnaires to measure sleep quality, physical exercise and quality of life, as well as to measure dietary adherence with 3-day food records. A descriptive analysis of qualitative variables will be performed with frequencies and percentages; quantitative variables will be presented according to their free or parametric distribution. An X2 will be performed to compare the difference between the proportions of the outcome variables, as well as a Student's t-test or Mann Whitney U test according to their parametric or free distribution. A multivariate analysis will be performed to see the effect of both interventions on the main outcome variables, obesity, dyslipidemia and glycemic control.

Study Arms (2)

Intervention Mediterranean diet

EXPERIMENTAL

Patients in this group will be given a normocaloric diet with the following energy distribution (Protein: 15-20%, Carbohydrate: 50-55%, Fat: 25-30%, Saturated fat: \<7%) according to the guidelines for adult patients with OSA. The Mifflin-St. Mifflin equation will be applied to determine the energy needs of each patient. They will receive individual nutritional counseling at the beginning of the study on hygienic sleep measures and Mediterranean-type diet adjusted to foods in Mexico. Pre-established menus will be calculated with foods that are characteristic of the Mediterranean-type diet, containing fruits, vegetables, whole grains, cereals, white meat content. Sample menus: Weekly menus will be designed to guide the indicated meal plan of the patients. The menus to be designed will be of 1200, 1400, 1600, 1800, 1800, 2000 and 2200 calories. Specifications will be given for the promotion of foods with higher complex carbohydrate content, white meats, fruits and vegetables.

Control

NO INTERVENTION

Patients in this group will be given a normocaloric diet with the following energy distribution (Protein: 15-20%, Carbohydrate: 50-55%, Fat: 25-30%, Saturated fat: \<7%) according to the guidelines for adult patients with OSA. The Mifflin-St. Mifflin equation will be applied to determine the energy needs of each patient. To achieve energy needs and distribution, a specific meal plan containing common foods divided into food equivalent groups will be administered to patients. Nutritional counseling will be considered on an individual basis on hygienic sleep measures and type of diet for weight loss according to age, sex, current body weight and present comorbidity. At the beginning of the intervention, a 24-hour food reminder will be made to know their usual diet. They will be given a triptych for adherence to the indicated diet.
