About

The aim of the present randomized controlled study was to examine wether a clinical decision support stystem would increase the adherence to the Mediterranean diet (MD) of adolescent girls, aged 15-17 years, diagnosed with polycystic ovary syndrome. The intervention lasted for 3 months and in total, 40 girls were randomly assigned to either the MD group (n=20) or a Control group receiving general nutritional advice (n=20). Anthropometry, nutritional intake, psychological well-being, and blood markers were analyzed at the begninning and the end of the trial.

Full description

The aim of the present randomised controlled trial was to investigate the effects of a Mediterranean Diet (MD) intervention delivered through a Clinical Decision Support System (CDSS) on various dietary, health parameters and anxiety in adolescent females, aged 15-17 years, with PCOS. A randomized controlled trial was conducted with 40 adolescent females diagnosed with PCOS, randomly assigned to either an Intervention group (IG) (n=20) or a Control group (CG) (n=20). The IG received personalized dietary guidance based on the MD principles, delivered through a CDSS, while the CG received general nutritional advice. Measurements of dietary intake, anthropometric indices, biochemical markers, and psychological well-being were collected at baseline and after a 3-month intervention period. After 3 months, significant improvements were observed in the IG compared to the CG. Adherence to the MD increased significantly in the IG, leading to decreased caloric intake, fat, saturated fatty acids, and dietary cholesterol, and increased intake of monounsaturated fatty acids. Conversely, the CG experienced an increase in fat and dietary cholesterol intake. Both groups exhibited an increase in fiber intake, with a more pronounced rise observed in the MD group. Psychological well-being showed a significant reduction in anxiety levels in the IG group, while no significant change was observed in the CG. The intervention led to improvements in dietary patterns, body composition, and psychological well-being. These results underscore the importance of dietary interventions tailored to the MD principles in the management of PCOS among adolescent females.

40 participants in 2 patient groups

Intervention Group
Active Comparator group
Description:
Each participant was assigned to a highly skilled dietician. The dietician implemented an individualized daily dietary regimen according to the Mediterranean diet produced by the clinical decision support system (CDSS) software. The CDSS was utilized to calculate all necessary components for the synthesis of the dietary plan, which was renewed every 15 days. Participants of the Intervention group obtained unique login credentials for the CDSS and received instruction on its operation from the designated dietitians. They were directed to access their CDSS account remotely on a weekly basis in order to monitor their nutritional status (body weight and healthy eating) and to complete a three-day dietary journal; this information was automatically accessible to the dietitians. Telephone interviews were conducted every other week in order to supplement the nutritional and lifestyle consultations. In addition, unanticipated phone calls requesting 24-hour dietary recalls were received.
Treatment:
Other: Mediterranean diet group
Control Group
No Intervention group
Description:
The Control group participants were not provided with CDSS. They simply got basic lifestyle instructions based on the "National Dietary Guidelines for Children and Adolescents" during phone call sessions with the dieticians every 15 days. The ladies in the Control group were directed to maintain a food diary for three consecutive days each week, which they then transmitted to the designated dietician via email. Once again, unsolicited phone calls were conducted in order to acquire 24-hour dietary recalls.
