Maternal age: The age of the mother at the time of delivery. Advanced maternal age is usually defined as age 35 or more at delivery. Advanced maternal age predisposes to Down syndrome (trisomy 21). The risk of having a Down syndrome baby rises with maternal age. It essentially doubles from 1 in 725 at maternal age 32 to 1 in 365 at maternal age 35. And the risk continues to climb with the years and is 1 in 32 at maternal age 45.
Next comes the pubertal growth spurt. Lastly, menstruation begins (called menarche), on average, 2-2.5 years after the onset of puberty. The mean age for a girlâs first period is 12.75 years.Wide variations are seen in the sequence and timing of these events, but peak growth velocity (fastest growth rate) always precedes menarche.ow for the crucial information: The earlier before age 12 a girl starts her period, the higher her lifetime risk for breast cancer (probably from the prolonged estrogen exposure). The highest average risk for breast cancer is in non-Hispanic white women, where it is 1 in 8, or 12.5%.
