Determinants of Insulin Sensitivity by Age, Sex, Race/Ethnicity, BMI, and PCOS Diagnosis

Sponsored by Ali Chappell

About this study

The study aims to investigate the relationship between fasting insulin and Homeostatic Model Assessment of Insulin Resistance (HOMA-IR) across various demographic factors, including age, sex, race/ethnicity, BMI, and polycystic ovary syndrome (PCOS) diagnosis. By analyzing these variables, the study seeks to identify potential variations in insulin levels, which could provide valuable insights into the impact of different factors on metabolic health and the development of insulin-related conditions.

This study aims to investigate the significance of measuring fasting insulin and the homeostatic model assessment of insulin resistance (HOMA-IR) in identifying metabolic health across various demographic and clinical factors. Specifically, the study will examine the influence of age, sex, race/ethnicity, BMI, and polycystic ovary syndrome (PCOS) diagnosis on insulin levels and insulin resistance as essential indicators of metabolic dysfunction. Metabolic health disorders, such as insulin resistance and impaired glucose metabolism, are known to be associated with an increased risk of developing conditions like type 2 diabetes, cardiovascular diseases, and metabolic syndrome. Traditionally, glucose levels have been used to assess metabolic health; however, fasting insulin and HOMA-IR provi…

Only the research team can confirm whether you qualify. The intake questionnaire is the best way to find out.

Completing a questionnaire on Clinably does not enroll you in a clinical trial or confirm your eligibility. Only the research team can determine whether you qualify to participate. These results are based on the information you provide and are intended to help you start a conversation with the research team.
