Résumé : Large-for-gestational-age (LGA) and macrosomic births pose significant maternal and neonatal health risks, particularly in low- and middle-income countries (LMICs), where access to care are often limited. Despite well-established associations between LGA, macrosomia, and various risk factors, the relative contributions of these factors remain underexplored in LMICs. This study aims to identify risks factors for LGA and macrosomia in LMICs, with an emphasis on modifiable ones, and quantify their population attributable fractions (PAFs).
