AI simplified

Abstract

Participants with had a mean obesity duration of 20 years compared to 11 years for those with later-onset obesity.

  • Individuals with early-onset obesity presented higher baseline BMI (40 kg/m) and waist circumference (118 cm) compared to those with later-onset obesity (37 kg/m and 112 cm, respectively).
  • Lower baseline levels of HbA1c (5.48% vs. 5.60%) and triglycerides (120 mg/dL vs. 130 mg/dL) were observed in participants with early-onset obesity.
  • Systolic blood pressure was lower in participants with early-onset obesity at baseline (121 mmHg) compared to later-onset individuals (125 mmHg).
  • Weight loss and improvements in waist circumference, HbA1c, triglycerides, and systolic blood pressure with tirzepatide at 72 weeks were consistent across both early- and later-onset obesity subgroups.
