Primary Outcome Measures:
  • Generate Preliminary Data on the Range of Outcome Measures at Baseline and After 6 Months of Fiber Supplementation in Terms of: Ovulation Rates, Insulin Sensitivity, Concentrations of Circulating Androgens and Satiety. [ Time Frame: 10 months ]

Secondary Outcome Measures:
  • Quantify Enrollment Strategies, Retention, Compliance, Participant Characteristics, and Data Collection Challenges. [ Time Frame: 10 months ]

Enrollment: 2
Study Start Date: February 2008
Study Completion Date: March 2010
Primary Completion Date: March 2010 (Final data collection date for primary outcome measure)
Arms Assigned Interventions
Experimental: Fiber-Stat
2 tablespoons daily
Drug: Fiber-Stat
Liquid fiber supplement, 2 tablespoons twice daily.

Detailed Description:
We hypothesize that 6 months of fiber supplementation will improve ovulation in women with PCOS by improving insulin sensitivity independent of weight loss. In this pilot study, we will determine the feasibility of conducting a larger double-blind, randomized trial in women with PCOS to test this hypothesis. We will evaluate 15 women over a 10-month period, starting with a 4-month intervention-free observation period to determine the effect on ovulation of adding up to 22g/day of fiber supplementation to their usual weight-maintenance diets (to achieve 28-36 g fiber/day assuming baseline dietary fiber intake, could feasibly be translated into clinical practice.
