Persistent physical inactivity during adolescence (ages 16-18) strongly and independently predicts the development of adult obesity and abdominal obesity by age 25, establishing a causal link between early sedentary behavior and later adiposity.
If you are a teenager or young adult, staying physically active is one of the most powerful things you can do to prevent obesity later in life. It doesn't matter if your parents are overweight; your activity level during your teens is a stronger predictor of your adult weight than your genes. Start moving now to break the cycle of inactivity and weight gain.
Physical inactivity in adolescence strongly predicted the risk for obesity (odds ratio (OR) 3.9, 95% confidence interval (CI) 1.4–10.9) and abdominal obesity (4.8, 1.9–12.0) at age 25, even after adjusting for baseline and current BMI.
Why this rating
High-quality longitudinal twin cohort design with objective metabolic measurements (DLW, accelerometry) controlling for genetic factors.

More from this paper
- Once obesity is established, it creates a self-perpetuating vicious circle where obese individuals exhibit significantly lower physical activity levels and avoid high-intensity exercise, leading to lower total energy expenditure relative to body mass despite higher basal metabolic rates.Good
- Abdominal obesity is more strongly predicted by adolescent physical inactivity than overall obesity, and self-perceived poor fitness in adolescence is a significant independent risk factor for adult abdominal obesity.Good
