How diet relates to cardiometabolic health in Rosario

Is this trial a fit for you?

A plain-English reading of the study's rules. Only the study team can confirm whether you qualify.

What this trial studies

This is a cross-sectional observational study comparing adults who follow vegan, ovo-lacto-vegetarian, or omnivorous diets in Rosario, Argentina. Participants provide demographic and medical history and undergo dietary interviews, anthropometric measurements, body composition, blood pressure, grip strength, and blood tests for cardiometabolic biomarkers. People on medications that affect blood pressure, lipids, or glucose and those with major chronic diseases are excluded to reduce confounding. The goal is to compare diet characteristics and cardiometabolic risk profiles across the three diet groups.
