Study Details

Study Description

Brief Summary

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.

Detailed Description

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 provide valuable insights into the underlying insulin dysregulation that precedes the onset of these conditions.

Disparities in insulin levels have been observed across different racial and ethnic groups. These variations may arise from genetic predispositions, differences in lifestyle, or a combination of both, thus highlighting the need to explore these factors comprehensively. BMI, a measure of body composition, has been strongly associated with elevated insulin levels and insulin resistance. Individuals with obesity often exhibit dysregulated insulin metabolism, leading to higher fasting insulin and HOMA-IR values. Furthermore, PCOS, a common endocrine disorder affecting reproductive-age women, is frequently associated with insulin resistance. Studying the insulin profiles among women with PCOS will shed light on the potential metabolic implications and help tailor interventions for this at-risk population.

The study will employ a cross-sectional design, enrolling a large sample of participants from diverse backgrounds. Fasting insulin levels will be measured using standardized laboratory methods, and HOMA-IR scores will be calculated based on fasting insulin and glucose values. Statistical analyses, including regression models and subgroup comparisons, will be conducted to assess the associations between fasting insulin, HOMA-IR, and the demographic and clinical factors of interest.

This research aims to emphasize the importance of incorporating fasting insulin and HOMA-IR measurements alongside glucose assessments to enhance the identification and understanding of metabolic health disorders. The findings are expected to contribute to a more comprehensive approach in diagnosing, managing, and preventing metabolic diseases, ultimately leading to improved patient outcomes and public health interventions.

Outcome Measures

Primary Outcome Measures

Assessment of Fasting Insulin levels and HOMA-IR (Homeostatic Model Assessment for Insulin Resistance) scores among different groups stratified by age, sex, race/ethnicity, BMI, and PCOS (Polycystic Ovary Syndrome) diagnosis. [3 years]
The primary objective is to investigate the association between these measures and the specified demographic and clinical factors, providing insights into the variations and potential disparities in insulin resistance across different subgroups.

Secondary Outcome Measures

Identify any significant interactions or relationships between the primary outcomes (Fasting Insulin and HOMA-IR) and the demographic and clinical factors, including age, sex, race/ethnicity, BMI, and PCOS diagnosis. [3 years]
The secondary outcome measure will provide a comprehensive understanding of how various factors may influence insulin resistance and contribute to its heterogeneity in different populations.
