Adolescent adiposity (BMI ≥ 25 kg/m² at age 18) is independently associated with a significantly increased risk of premature death in adulthood, even after adjusting for adult BMI and lifestyle factors.
Maintaining a healthy weight during adolescence is critical for long-term survival. Even if you gain weight as an adult, being overweight as a teenager adds an independent layer of mortality risk that isn't fully erased by later weight management. Focus on healthy habits early in life.
Associations between BMI at age 18 years and death could only partly be explained by adult BMI measured in 1989. Moderately higher adiposity at age 18 years is associated with increased premature death in younger and middle-aged U.S. women.
Why this rating
Large prospective cohort (N=102,400), long follow-up (12 years), adjusted for multiple confounders, but observational design limits causal inference.
