To Estimate the Prevalence of PCOS in Obese Premenopausal Women and Elucidate How They Respond to a Weight Reduction Treatment Program
In Brief
An observational study evaluating Weight reduction regimen for Polycystic Ovary Syndrome. Completed, enrolled 300 participants across 1 site.
Detailed Summary
Between 40% and 85% of women with Polycystic Ovary Syndrome (PCOS) are overweight or obese and obesity is closely linked to the development of PCOS. Although it is well established that obesity increases the severity of the clinical features of PCOS, data regarding the prevalence of PCOS in obese women and the change in body weight in women with PCOS over time are scares. In a prevalence study it was investigated whether obesity increases the risk of PCOS in the general population and they demonstrated that the prevalence rate of PCOS in underweight, normal-weight, overweight, and obese women were 8.2, 9.8, 9.9, and 9.0%, respectively, similar to that observed in the general population. These results suggest that the risk of PCOS is only minimally increased with obesity. On the other hand, in a Spanish prevalence study among overweight and obese subjects, they demonstrated a 28.3% prevalence of PCOS, which is markedly higher compared with the 5.5% prevalence of PCOS in lean women in Spain. First the investigators aim to estimate the prevalence/probability of PCOS among obese, premenopausal women (between 18 and 50 years) with no symptoms of classic menopausal symptoms in Sweden. Secondly, to elucidate whether women diagnosed with PCOS respond to standard weight reduction regime to the same extent as women without PCOS.

Timeline
Interventions
The dietary intervention begins with a 12-weeks VLCD/LCD period. The diet comprise of 3 to 5 portions liquid diet with a daily energy intake of 450-800 kcal. In addition, patients will be encouraged to drink 1,5-2L daily of non-caloric beverages (\<6 kcal/100 ml). All patients will have scheduled nurse visits at week 0 (baseline), 2, 5, 8, and 12. At these visits general well-being and body weight will be monitored. The patient will also be given support and counselling to enhance compliance to the VLCD/LCD diet.
