The strongest maternal characteristic associated with giving birth to a baby with Down syndrome is higher maternal age, particularly in women over the age of 35. The likelihood of having a baby with Down syndrome increases as maternal age at pregnancy increases. Low levels of intelligence in the mother, alcohol consumption during pregnancy, and exposure to lead or mercury by the baby after birth are not directly linked to an increased risk of Down syndrome.
