WHO世界卫生组织：2030年全球营养目标：低出生体重简报（英文版）

Low birth weight is defined by the World Health Organization (WHO) as weight at birth less than 2500 g (5.5 lb). Low birth weight continues to be a significant public health problem globally and is associated with a range of both short- and long-term consequences. In the short term, low birth weight is strongly linked to increased neonatal mortality and morbidity.
