A healthy mom ‘key to baby size’, say researchers

Newborn babies born to healthy, well nourished mothers are strikingly similar in size the world over, scientists have shown.

On average, they have a body length of 19.45 inches, an international study found.

Previously it was suggested that ethnicity was largely responsible for the widespread variation seen in the size of babies born around the world.

The new research suggests race and ethnicity contribute little to baby size. What matters more is the education, health and nutrition of mothers, and the care they receive during pregnancy.
