ELSA-Brasil: Abdominal Obesity Indicators and Cutoff Points for Brazilian Adults

12,232 participants aged 35-74 from the ELSA-Brasil longitudinal health study were used to evaluate the accuracy of three abdominal obesity indicators: waist circumference, waist-hip ratio, and conicity index. The study defined a latent variable as the gold standard and identified sex- and race-specific cutoff points for these indicators. It was authored by Michaela Eickemberg and is available via paperswithcode under an Open Access license.

Use Cases

• Validate diagnostic cutoff points for abdominal obesity based on waist circumference, waist-hip ratio, and conicity index.
• Compare the discriminatory power of different obesity indicators across sex and racial groups.
• Study the prevalence of abdominal obesity in a large Brazilian adult cohort.
• Apply latent variable modeling to establish a gold standard for a clinical condition.

Strengths

• Includes data from 12,232 participants, providing a substantial sample size.
• Analyses are stratified by sex and race/skin color, allowing for subgroup-specific insights.
• Provides specific cutoff point values for three different indicators across demographic groups.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count for the underlying dataset is unknown, which may limit suitability assessment.
• Data may reflect geographic and demographic bias inherent to the ELSA-Brasil cohort.
