The odds of having a premature baby are 12.2% in Kansas.

A March of Dimes report released Tuesday mapped the stark state-by-state disparities in what it called a "report card" on prematurity — to track progress toward meeting a federal goal of lowering preterm births.

Kansas ranked in the middle of the states.

The government's goal: No more than 7.6% of babies born before completion of the 37th week of pregnancy.

The report found a link between prematurity and high rates of smoking and a lack of insurance.

In Kansas, 17% of women of childbearing age lack insurance and 19.8% of them smoke.
