Study uncovers link between childhood overweight and obesity and chronic obstructive pulmonary disease in adulthood

Research suggests that having an overweight or obesity trajectory during childhood is associated with a higher risk of chronic obstructive pulmonary disease (COPD) in adulthood. The study found that women with above-average childhood BMI trajectories had a 26% higher risk, while those with an obesity BMI trajectory had a 65% higher risk.
