MeDiApp-PCOS: A Mobile Mediterranean Diet App for Women With Polycystic Ovary Syndrome

Официальное название

Randomized Controlled Trial of a Mobile Application With Personalized Mediterranean Diet-Based Recommendations in Women With Polycystic Ovary Syndrome

Обзор

This randomized clinical trial will test whether a mobile application with personalized Mediterranean diet-based recommendations can improve health outcomes in women with polycystic ovary syndrome compared with standard lifestyle advice. Participants will be assigned to either the mobile application group or the standard lifestyle advice group. The primary outcomes are change in LDL cholesterol and change in body mass index after 3 months. Secondary outcomes include changes in metabolic and hormonal measures, quality of life, treatment adherence, and ovulatory function assessed through 6 months.

Вмешательства

• Поведенческое Mobile Application-Based Personalized Mediterranean Diet and Lifestyle Intervention
  The intervention consists of a mobile application providing personalized Mediterranean diet-based nutrition plans, a food database with nutritional information, automatic calculation of caloric intake and macronutrient composition, monitoring of adherence to the Mediterranean diet, physical activity recommendations (including minimum weekly minutes of moderate aerobic activity and strength training), an activity diary with step tracking, automated feedback and motivational messages, weekly progr
• Поведенческое Standard Lifestyle Advice for PCOS
  Standard care consisting of written lifestyle recommendations for women with polycystic ovary syndrome. This includes printed materials describing the Mediterranean diet (principles, recommended and discouraged foods, example menus), physical activity recommendations, and general educational information on PCOS and the importance of lifestyle changes. Participants will receive a one-time dietitian consultation at baseline to review the recommendations and will be advised to keep a paper diary
