Investigating fasting insulin and insulin resistance across different demographics

Measuring Fasting Insulin and HOMA-IR by Age, Sex, Race/Ethnicity, BMI, and PCOS Diagnosis

Observational Lilli Health · NCT05950282

This study looks at how fasting insulin levels and insulin resistance vary among different groups of people based on age, sex, race, weight, and conditions like PCOS to better understand metabolic health.

What this trial studies

This observational study aims to explore the relationship between fasting insulin levels and the Homeostatic Model Assessment of Insulin Resistance (HOMA-IR) in relation to various demographic factors such as age, sex, race/ethnicity, BMI, and the diagnosis of polycystic ovary syndrome (PCOS). By analyzing these variables, the study seeks to uncover potential variations in insulin levels that could provide insights into metabolic health and the risk of insulin-related conditions. The findings may help identify how different factors contribute to insulin dysregulation and metabolic disorders.

Who should consider this trial

Good fit: Ideal candidates for this study are adults aged 18 and older, regardless of sex, from diverse racial and ethnic backgrounds, with varying BMI values, including those with and without a PCOS diagnosis.

Not a fit: Patients under 18 years old or those with other endocrine disorders affecting insulin levels may not benefit from this study.

Why it matters

Potential benefit: If successful, this study could enhance understanding of metabolic health and lead to better management strategies for conditions like insulin resistance and PCOS.

How similar studies have performed: While there have been studies examining insulin resistance and demographic factors, this specific approach focusing on the interplay of multiple variables in a diverse population is relatively novel.
