Polycystic Ovary Syndrome

Brief summary

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.

Detailed 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.

Interventions

Females who met the inclusion and exclusion criteria were allocated in groups of one to either the Control group or the Intervention (MD) group using a random assignment method applied by an independent statistician. During the trial, every participant in both groups had two individual sessions with the assigned researchers. These sessions took place at the beginning of the trial and three months later, and involved anthropometry measurements, evaluation of dietary habits, assessment of psychological well-being, and collection of blood samples. Treatment allocation was not revealed to the appointed statistician until the end of the study and release of the final outcomes.

Masking description

Treatment allocation was not revealed to the appointed statistician until the end of the study and release of the final outcomes.

Intervention model description

Recruitment involved adolescents with polycystic ovary syndrome. Participants, who expressed their willingness to take part, attended personal meetings with the appointed dieticians who provided comprehensive explanations on the objectives, methods, and the potential benefits/risks of the study. A leaflet with related information was provided to all patients. Every eligible volunteer, and their guardian, signed a written informed consent and then kept a hard copy of the signed document. All eligible females were recruited in 12/2019 and were randomly allocated in groups of one to either the Control group (CG) or the Intervention group (IG). The IG received a personalized Mediterranean dietary plan, delivered through a clinical decision support system, while the CG received general dietary advice. Every participant had two individual sessions with the assigned dietician, at the beginning and at the trial endpoint, which involved anthropometry, dietary assessment, and blood withdrawal.
