What is the clinical evidence from this study?

Study design: Observational. Population: Obesity-related cardiovascular mortality. Primary outcome: Temporal trends in age-adjusted mortality rates (AAMRs) measured by average annual percent change (AAPC).

What does this research mean for the field?

Obesity-related cardiovascular mortality in the U.S. increased significantly from 1999 to 2020, with males exhibiting a steeper average annual percent change than females (5.94% vs. 4.40%) alongside marked racial and geographic disparities. Novelty: ClaimNovelty.INCREMENTAL. Consensus alignment: ConsensusAlignment.NEUTRAL.

Comparison

Mortality trends stratified by sex, ethnicity, census region, state, and urbanization level

Design

Retrospective national death certificate study using CDC WONDER database

Population

Obesity-related cardiovascular mortality in the U.S. has increased significantly over the past two decades, with disproportionate impacts on males, non-Hispanic Black populations, and rural areas.

Limitations

Ecological analysis based on aggregated mortality data, precluding individual-level causal inferences
Reliance on death certificate data, which may be subject to misclassification and temporal changes in coding practices
Absence of individual-level clinical, socioeconomic, and behavioral information precludes adjustment for confounders
Joinpoint regression identifies inflection points but does not provide insight into underlying drivers
Data available only through 2020
ICD-10 codes I00-I99 encompass a broad spectrum of cardiovascular conditions, limiting subtype-specific insights
