Metabolic Waiting Game: GLP-1 Access and the Inequality Paradox

• In Event: Fundamental Cause Theory at 30: Rethinking Health Inequities

Abstract

This study investigates the structural mechanisms of the “Metabolic Waiting Game,” a process where insurance coverage policies create severe health inequalities for patients prescribed antipsychotic medications who require concomitant treatment to prevent weight gain. These medications stabilize psychiatric symptoms but induce severe metabolic side effects. Glucagon-like peptide-1 (GLP-1) receptor agonists offer a vital intervention. Institutional coverage models frequently subordinate this clinical necessity to rigid administrative protocols. This structural exclusion instigates a cycle of deferred treatment, transforming a manageable clinical side effect into progressive metabolic damage and diminished quality of life.

Using retrospective clinical data from a Southern California safety-net healthcare system between 2016 and 2025, this study tracks adult patients initiating high-risk psychotropic medications. The primary outcome is the concomitant prescription of a GLP-1 medication. The secondary outcome measures the discontinuation of GLP-1 therapy which requires continuous use to improve metabolic health. We utilize multivariate logistic regression and covariate balancing methods to analyze these outcomes across sociodemographic factors, insurance status, and the Area Deprivation Index.

Grounded in Fundamental Cause Theory and the inequality paradox, we project that African American and Hispanic patients, as well as patients residing in areas with high community-level deprivation, are less likely to receive a concomitant GLP-1 prescription. We anticipate public insurance functions as a primary institutional barrier. Furthermore, we hypothesize that patients residing in areas with high community-level deprivation will demonstrate higher rates of medication discontinuation. This research aims to elucidate the underlying architecture of health inequality. It highlights how administrative burdens serve as modern mechanisms of stratification, distributing the benefits of medical innovation unequally based on flexible resources and health capital, ultimately underscoring the profound disparities embedded within psychiatric patient care.
