More than one day of early pregnancy bleeding linked to lower birth weight

Women who experience vaginal bleeding for more than one day during the first trimester of pregnancy may be more likely to give birth to a smaller baby, researchers at the National Institutes of Health, US, have suggested.

On average, full-term babies born to women with more than one day of bleeding in the first trimester were approximately three ounces lighter than those born to women who reported no bleeding during this time.

In addition, babies born to women with more than a day of bleeding in the first trimester were roughly twice as likely to be small for their gestational age - a category that includes infants who are healthy but small and those whose growth has been restricted because of insufficient nutrition, oxygen or other causes.

The researchers said the decrease in birth weight of babies born to women experiencing vaginal bleeding was small. They added that more studies are needed to establish if these infants are at risk for any additional health risks in infancy or later life.ADNFCR-2094-ID-801846664-ADNFCR
