Polycystic Ovary Syndrome (PCOS) - Effect Of Physical Exercise And Electroacupuncture (PCOSNTS)

This study has been completed.

The overall hypothesis is that women with PCOS, both obese and non-obese, have larger adipocytes, altered metabolism and signs of inflammation in adipose tissue and that these changes are associated with high sympathetic nerve activity, hyperandrogenism hyperinsulinaemia, insulin resistance with progression to type II diabetes and cardiovascular disease (CVD) as well as psychological distress and reduced quality of life. Physical exercise and electro-acupuncture decrease high concentrations of androgens, induce regulare menstrual pattern, inhibits high sympathetic activity and restore the PCOS induced disturbances.

Primary Outcome Measures:
  • To measure if physical exercise and electro-acupuncture restores endocrine, neuroendocrine, metabolic and immunological disturbances related to sympathetic nerve activity as well as psychological distress and improve quality of life in women with PCOS. [ Time Frame: One year ]

Enrollment: 84
Study Start Date: October 2005
Study Completion Date: October 2008
Primary Completion Date: October 2008 (Final data collection date for primary outcome measure)
Arms Assigned Interventions
Experimental: Low-frequency electro-acupuncture Procedure: Electroacupuncture
Experimental: Physical exercise Procedure: Physical exercise
Active Comparator: Untreated control Procedure: Untreated control

Detailed Description:

Primary outcome: Changes in androgen concentrations and menstrual pattern

Secondary outcome: changes in sympathetic nerve activity, uterus peristalsis, ovarian morphology, adipose tissue related variables, insulin sensitivity, coagulation factors and health related quality of life and symptoms of anxiety and depression.
