Objectives: Metabolic dysfunction-associated steatotic liver disease (MASLD) is associated with substantial clinical and economic burden. Fibrosis detection is key to disease management, but biopsy-defined staging is invasive, expensive, and associated with complications. We evaluated healthcare resource utilization (HCRU) and costs by disease stage using biopsy-defined staging and fibrosis-4 (FIB-4; a simple, well-validated, non-invasive tool for assessing fibrosis severity), and compared their utility for predicting long-term outcomes in MASLD.

Aims: Economic simulation models, such as the IHE Type 2 Diabetes Cohort Model (IHE-DCM-T2), are used widely to inform resource allocation for Type 2 Diabetes (T2D) treatments. Recently, IHE-DCM-T2 was augmented with Japanese-specific risk equations to align with the Japanese healthcare context. This study extends prior model validation of IHE-DCM-T2 to cover the Japanese risk equations for applications in Japan's clinical setting and healthcare system.

Aim: Body mass index (BMI) in Japan has increased over the past decades, leading to corresponding increases in the risks of complications such as type 2 diabetes (T2D). We modelled the impact of weight loss on the incidence of 10 specific complications and resulting healthcare costs in a Japanese cohort.

Materials And Methods: We adapted our value of weight loss simulation model to represent a cohort of 100,000 Japanese individuals aged 20-69 years with a BMI of 25-50 kg/m.

Obesity continues to represent a significant public health concern, with a broad impact from both a health and economic perspective. This analysis assesses the fiscal consequences of overweight and obesity (OAO) in Japan by capturing obesity-attributable lost tax revenue and increased government transfers using a government perspective. The fiscal burden of OAO was estimated using an age-specific prevalence model, which tracked the Japanese population across different body mass index (BMI) categories.

Introduction: The prevalence of obesity has increased worldwide over the past decades. Regional variations exist in the relationship between body mass index (BMI), body fat, and health risks: Asians typically have a lower BMI than people of European descent, but a higher risk of obesity-related comorbidities. However, there is a paucity of evidence for anti-obesity medications (AOMs) in East Asian populations.
