A coalition of medical and community groups wants to decrease Hamilton County's high infant mortality rate. The county has an infant mortality rate of ten-point-five for every one-thousand live births. That's significantly higher than the state average of seven-point-six. The infant mortality rate is the number of babies that die before their first birthday. The coalition -- which includes the March of Dimes and Cincinnati Children's Hospital Medical Center -- seeks to bring the county's infant mortality rate equal to or below the national average of seven in five years. Infant mortality is a complex problem. Leading causes include birth defects and premature delivery. Risk factors include poverty, lack of prenatal care, maternal smoking and poor nutrition.
