Michigan babies are getting a better start in life overall.
A 2009 Right Start in Michigan report Tuesday shows the rate of women who smoked while pregnant dropped more than one-third from 1992 to 2007.
The rate of teen births and repeat teen births declined by more than a quarter, while births to women with less than 12 years' education dropped 15 percent.
The rate of women who got late or no prenatal care fell 15 percent.
Not all factors were positive, however. The rate of births to unmarried females grew 10 percent over the 15 years.
And the percentage of low-birthweight babies also worsened by 10 percent, although the rate of premature babies dropped 9 percent.
