柳叶刀重磅：每四个成年人，就有一个应接受GLP-1药物治疗肥胖！

Core Viewpoint - Obesity is becoming one of the most systemic public health risks globally, significantly increasing the incidence of non-communicable diseases such as type 2 diabetes and cardiovascular diseases, thus straining healthcare systems and financial resources [4] Group 1: GLP-1 Receptor Agonists - GLP-1 receptor agonists have evolved from diabetes treatment drugs to key tools in managing obesity and its complications, showing clear weight loss and cardiometabolic benefits in multiple randomized controlled trials [4] - A recent study published in The Lancet Diabetes & Endocrinology assessed the potential population size for GLP-1 receptor agonists in obesity treatment, integrating health survey data from 99 countries covering over 810,000 non-pregnant adults aged 25 to 64 [5] - The study defined eligibility for GLP-1 receptor agonists based on BMI thresholds, with a general standard of BMI ≥ 30 kg/m² or BMI ≥ 27 kg/m² with hypertension and/or diabetes, adjusting thresholds for Southeast Asia, East Asia, and South Asia due to increased metabolic risks at lower BMI levels [5] Group 2: Potential Patient Population - Approximately 27.0% of adults globally meet the medical criteria for GLP-1 receptor agonists for weight management, translating to a potential population size of about 799 million people, indicating that one in four adults may be medically suitable for this treatment [6] - The proportion of individuals who should use GLP-1 receptor agonists varies significantly by income level, with high-income countries at 41.8% and low-income countries at 11.7%, while nearly four-fifths of the potential patient population is concentrated in middle-income countries [6] - The regional distribution shows the highest applicability in Europe and North America at 42.8%, while Southeast Asia, East Asia, and South Asia, despite a lower applicability rate of 23.1%, have the largest absolute number of potential patients, approximately 639 million [6] Group 3: Demographic Characteristics - Among demographic characteristics, the proportion of women meeting medication standards is 28.5%, higher than men's 25.5%, with the percentage increasing significantly with age, reaching 38.3% in the 55 to 64 age group [7] - Income and education levels correlate with medication eligibility, showing a contrasting trend in different economies: higher income correlates with higher eligibility in low and middle-income countries, while in high-income countries, lower-income groups have the highest eligibility [7] Group 4: Challenges and Recommendations - The study highlights the substantial theoretical and medical demand for GLP-1 receptor agonists in global obesity prevention and treatment, but real-world implementation faces significant challenges, particularly in middle-income countries where data on drug accessibility and usage is limited [7] - The high cost of these medications poses a barrier to widespread adoption in the short term, with uncertain long-term impacts on healthcare budgets [7] - The authors emphasize that GLP-1 receptor agonists should not be viewed as a singular solution to obesity; a multifaceted approach combining drug treatment with structural long-term strategies is necessary to address the global obesity epidemic [8]
