Introduction: Overweight and obesity are frequently present in both women with polycystic ovary syndrome (PCOS) and with Hashimoto's thyroiditis (HT). This is a limited study regarding the benefits of lifestyle changes, including dietary habits, dedicated to patients with HT and PCOS.
Objective: The aim of the study was to assess the effectiveness of an intervention programme based on the Mediterranean Diet (MD) without caloric restriction and increased physical activity to change selected anthropometric parameters in women with both health conditions.
Material and methods: The intervention programme consisted of changing the participants diet towards MD rules and increasing physical activity for 10 weeks according WHO recommendation. The study involved 14 women diagnosed with HT, 15 with PCOS and 24 women from a control group. The intervention programme consisted of educating patients in the form of a lecture, dietary advice, leaflets and a 7-day menu based on MD. During the programme, patients were required to implement recommended lifestyle changes. The mean intervention time was 72 ± 20 days. Nutritional status was analyzed by body composition, degree of implementation of the principles of the MD by using the MedDiet Score Tool, and the level of physical activity by the IPAQ-PL questionnaire. The above-mentioned parameters were evaluated twice, before and after the intervention.
Results: The intervention programme consisting in implementing the principles of the MD and increasing physical activity to effect a change in the anthropometric parameters of all groups of women studied; all women had a reduction in body fat and body mass index. A decrease in waist circumference was observed in the group of patients with Hashimoto's disease.
Conclusions: An intervention programme based on the Mediterranean Diet and physical activity can be a good way to improve the health of HT and PCOS patients.
