Introduction
It is normal for a fetus to weigh between 5 to 8 jin (approximately 2.5 to 4 kilograms) at birth. Analysis should be based on the specific circumstances. If the baby is born preterm, the weight may be between 5 to 6 jin (approximately 2.5 to 3 kilograms); if born at term, the weight is usually between 6 to 8 jin (approximately 3 to 4 kilograms). Pregnant women should normally maintain a balanced diet, consume diverse nutrients, and engage in appropriate physical activity to promote the healthy growth of the fetus.
Generally, a fetal birth weight between 5 to 8 catties (approximately 2.5 to 4 kilograms) is considered normal. Analysis should be based on the specific circumstances. For preterm infants, the birth weight may range between 5 to 6 catties due to premature birth and incomplete development of organs and systems. For full-term infants, the birth weight is usually between 6 to 8 catties, as they benefit from adequate nutrient supply and a suitable growth environment throughout the complete gestational period, allowing for healthy development.
Preterm infants may have a lower birth weight, typically between 5 to 6 catties, because their organs and systems have not fully matured due to early delivery.
Full-term infants undergo complete development during pregnancy, supported by sufficient nutrition and an optimal intrauterine environment, resulting in a normal birth weight usually between 6 to 8 catties.
Pregnant women should maintain a balanced diet with diverse nutrient intake and engage in appropriate physical activity to support the healthy growth and development of the fetus.
