Wrzosek M, et al. - A relationship between the age at onset of obesity, metabolic parameters, and health problems was explored in bariatric surgery candidates. On analyzing a total of 469 unrelated adults with obesity prior to bariatric surgery, researchers noted a higher total body fat mass, and higher body fat percentage, and a 1.84 times higher risk of body mass index (BMI) above 40 kg/m² among patients with early onset of obesity than patients with adult onset of obesity (≥ 20 years). A younger age at obesity onset was noted to forecast a higher BMI in patients. These patients, however, showed less tendency for clinically manifesting well-established consequences of obesity, such as diabetes or hypertension, compared to patients with adult onset of obesity.
