Defining prenatal modifiable risk factors of childhood overweight and obesity has become critical as the need of primary preventive strategies increases. ⋯ Exceeding the recommended BMI-specific IOM GWG ranges has an adverse impact on the risk of childhood overweight and abdominal adiposity, whereas suboptimal GWG conveys no benefit or risk, reflecting a nonlinear relationship between absolute GWG and the risk of childhood overweight and adiposity. Strategies focussing on the awareness and prevention of excessive GWG and its consequences are justified.
