Epidemiology, LBW, preterm, IUGRAbstract
Low birth weight (LBW), defined as birth weight less than 2500 g irrespective of gestational age, is a major global public health issue associated with increased neonatal morbidity and mortality. Globally, nearly 20 million infants are born with LBW each year, accounting for approximately 14–15% of all births. The highest prevalence occurs in low- and middle-income regions, particularly South Asia. The two major mechanisms leading to LBW are preterm birth and intrauterine growth restriction (IUGR). This review summarizes global trends in LBW, with emphasis on South and Central Asia, and discusses the contributions of prematurity, fetal growth restriction, and major maternal and environmental risk factors.
