Forward QI-Module 1: Introduction to Obesity

Video Transcription

Video Summary

Dr. Stacey Chronister presents 2023 updates introducing obesity as a serious, progressive chronic disease driven by energy imbalance and complex neurohormonal regulation. Obesity is commonly defined using BMI (≥30 kg/m²), though BMI has limitations and differs by population (e.g., lower cutoffs in Asian populations); alternative measures include waist circumference and body fat assessment. Staging should consider health impact, and the Edmonton Obesity Staging System better predicts mortality by incorporating comorbidities and functional impairment rather than BMI alone. U.S. prevalence has risen from ~30% (1999–2000) to ~40% (2015–2016), with projections that by 2030 about 75% of adults may be overweight or obese; disparities exist by age, race/ethnicity, and socioeconomic status. Obesity meets disease criteria due to physiologic dysfunction and associated morbidity (diabetes, cardiovascular disease, certain cancers, infertility, and increased mortality). Appetite and eating behavior involve homeostatic, executive, and hedonic drivers influenced by brain pathways, genetics (~70% predisposition), medications, endocrine factors, and environment. Management is underutilized: obesity is often undocumented, few receive treatment, <2% receive anti-obesity medications, and surgery is under-recommended despite evidence.
