Mediterranean Diet as Treatment for Normal Weight Women With PCOS
A study testing mediterranean diet and normocaloric diet in people with Polycystic Ovary Syndrome, run by Azienda Ospedaliera OO.RR. S. Giovanni di Dio e Ruggi D'Aragona at 1 site in Italy.
Trial summary
Polycystic ovary syndrome (PCOS) is the most common endocrinopathy of reproductive-aged women characterized by chronic anovulation, hyperandrogenism and insulin resistance. Available guidelines recommend lifestyle intervention although they do not suggest the best dietetic regimen for the treatment of PCOS. Read more about this study

About this study
Official title: Mediterranean Diet: A New Nutritional Approach for the Treatment of Normal Weight Women With Polycystic Ovary Syndrome (PCOS)?
Polycystic ovary syndrome (PCOS) is the most common endocrinopathy of reproductive-aged women characterized by chronic anovulation, hyperandrogenism and insulin resistance. Available guidelines recommend lifestyle intervention although they do not suggest the best dietetic regimen for the treatment of PCOS. Thus, the purpose of this study is to compare the effectiveness of two nutritional protocols, namely Mediterranean Diet and standardized normocaloric Diet in normal weight women with PCOS.
Read the detailed description
PCOS is the most common endocrine disorder of reproductive age women, that is often characterized by chronic anovulation, hyperandrogenism and insulin resistance. The central importance of insulin resistance in the pathogenesis of the syndrome has been established by several in vivo and in vitro studies. No data are available for the best therapeutical approach for metabolic dysfunction of PCOS. In addition, although insulin resistance is a crucial pathogenetic factor for PCOS and lifestyle change program improves insulin resistance, no available data can also suggest whether non-obese women with PCOS benefit or did not from lifestyle change program including diet without calorie-restriction. Although there are not studies focused on the effectiveness and safety of Mediterranean diet in PCOS, several indirect studies performed in obese and/or insulin resistant subjects, seem to suggest a potential role of this diet in PCOS population and, in particular, on long-term PCOS-related health risk. In this study, the investigators' purpose is to compare two nutritional protocols in order to find the best dietetic approach for improving clinical, metabolic and hormonal outcomes in normal weight women with PCOS.

50 pcos women will be assigned to normocaloric mediterranean diet for 6 months
normocaloric dietOther
50 pcos women will be assigned to standardized normocaloric diet for 6 months
| Study group | Role | What they receive |
|---|---|---|
| Mediterranean Diet | Experimental | The diet programme will be characterized by carbohydrates (60 %); proteins (20 %, half comprised of vegetable proteins); total fat (20 %; saturated fat < 10 %). After calculating the patient's energy need, the amount of calories will be successively adjusted to mantain the same weight of the time of recruitment Receives: Other: mediterranean diet |
| normocaloric diet | Active comparator | 50% carbohydrates, 30% total lipids and 20% proteins. After calculating the patient's energy need, the amount of calories will be successively adjusted to mantain the same weight of the time of recruitment Receives: Other: normocaloric diet |
What is being measured
The primary outcome is the main question the study is designed to answer.
improvement in insulin resistance measured by HOMA index
Measured: 6 months
Secondary outcomes (3)
improvement in clinical parameters (Body mass index, normalization of menses, hirsutism, waist to hip ratio)
Measured: 6 months
improvement in metabolic parameters(total, LDL and HDL cholesterol)
Measured: 6 months
improvment in hormonal parameters (Testosterone, Androstenedione, DHEAS, FSH, LH, beta estradiol)
Measured: 6 months

Where is the study taking place?
The record lists 1 site in Italy. Whether a site is taking part right now should be confirmed with that site. See every site.
What are the possible benefits and risks?
They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

What does the primary outcome measure?
improvement in insulin resistance measured by HOMA index (time frame: 6 months). It is what the study was designed to measure, not a finding.
Where can I read the original study information?
On the ClinicalTrials.gov record for NCT02396264, which also lists 4 linked publications.
Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
How often is this information updated?
AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 19 Apr 2016.
