About this trial
This pilot randomized controlled study will plan to enroll 36 adolescent females with Polycystic Ovary Syndrome (PCOS)/Polyendocrine Metabolic Ovarian Syndrome (PMOS) to evaluate the effectiveness and feasibility of a tailored dietary intervention which will be termed "Beef+", that will emphasize the incorporation of unprocessed, lean beef (\<10% fat) as part of a healthy meal plan to improve glycemic control, diet quality, and health-related quality of life

Treatments tested in this trial
Beef+
Other interventionAdolescents will be instructed to consume a minimum of 1 (3oz) serving per day of cooked unprocessed, lean (\<10% fat) beef (21 oz/week) for 12 weeks. To facilitate adoption, the intervention will be offered at the household level, but it is not a requirement. The intervention is a multi-modal behavior change intervention with three overarching components: modifying beef intake, consuming beef in healthy meals, and the research team purchasing the beef needed for the intervention. To facilitate adoption of lean beef as part of a healthy diet, a study RDN will meet with the participant and at least one representative parent/guardian at bi-weekly check-ins to provide tailored dietary support and develop an implementation plan. A financial supplement of $100/month will be provided offset grocery costs.
Treatment groups
Trial outcomes
Primary outcomes
Change in HbA1c
HbA1c measured as point of care using A1CNow+ point-of-care analyzer, HbA1c will also serve as a safety endpoint.
Secondary outcomes
Change in 2-hour Fasting Glucose
Derived from a 75g oral glucose tolerance test (OGTT) as a measure of glycemic variability
Dropout rate
Drop-out and the reason for drop-out will be recorded, and in both the intervention and usual lifestyle groups will be reported.
Change in Matsuda Index
Derived from a 75g oral glucose tolerance test (OGTT), measure of insulin sensitivity
Change in Insulinogenic Index
Derived from the 75g oral glucose tolerance test (OGTT), measure of insulin sensitivity
Other outcomes
Compliance- Lean beef intake by self-report
Intake of lean beef, assessed via 24-hour diet recalls
Compliance - Daily Survey
Intake of lean beef, assessed through daily logs of beef intake by providing portion sized objects that align with serving sizes and ask participants to take photos of their meals with the portion estimator, to ensure that both the meal planning is followed and portion sizes are met.
Compliance - Blood Biomarkers
Serum hemoglobin will also be assessed as a metric of compliance.
Participants' Quality of Life
This will be measured through the Pediatric Quality of Life (PedsQL) questionnaire. It includes 23 questions and is scored by reverse-scoring items and linearly transforming them to a 0-100 scale. Higher scores mean better health-related quality of life.
