Trends and Patterns in Obesity-Related Deaths in the US (2010-2020): A Comprehensive Analysis Using Centers for Disease Control and Prevention Wide-Ranging Online Data for Epidemiologic Research (CDC WONDER) Data

Abstract

Obesity is a significant public health issue in the United States, contributing to a range of chronic conditions and premature mortality. This study analyzes patterns in obesity-related deaths from 2010 to 2020 using the Centers for Disease Control and Prevention Wide-Ranging Online Data for Epidemiologic Research (CDC WONDER) database to identify trends and demographic disparities. A retrospective analysis was conducted using the CDC WONDER Database, focusing on mortality data associated with specific International Classification of Diseases, Tenth Revision (ICD-10) codes for obesity (E66.0, E66.1, E66.2, E66.8, and E66.9). Data were extracted for the period from January 1, 2010, to December 31, 2020. Mortality rates per 100,000 population were calculated and analyzed across different demographic groups, including age, gender, and race/ethnicity. The analysis revealed an overall increase in obesity-related mortality rates, rising from 1.8 per 100,000 in 2010 to 3.1 per 100,000 in 2020. Age-specific mortality rates showed a significant increase in older age groups, with the highest rates observed in individuals aged 55-64 years (6.4 per 100,000) and 65-74 years (7.2 per 100,000). Gender disparities were evident, with higher mortality rates in males (3.4 per 100,000) compared to females (2.8 per 100,000) by the end of the study period. Racial disparities were also noted, with Black or African American individuals experiencing the highest mortality rates (4.3 per 100,000). The study highlights a concerning upward trend in obesity-related mortality in the United States over the past decade, with notable disparities based on age, gender, and race. These findings underscore the need for targeted public health interventions and policies aimed at reducing obesity prevalence and its associated mortality. Further research should explore the underlying causes and contributing factors to these trends to develop effective strategies for obesity management and prevention. Among the notable strengths of this study include the observation that it leveraged a comprehensive and decade-long countrywide database with detailed and up-to-date ICD-10 codes and demographic data to offer in-depth insights into obesity-related disparities and mortality trends in the United States. Nevertheless, the findings of this study have been limited by its increased focus on the United States' data, depending only on mortality records devoid of consideration of morbidity, alongside the lack of detailed data on lifestyle factors and comorbid conditions.
