Trimester of Prenatal Care
It is most beneficial for prenatal care to begin in the first trimester and continue throughout the pregnancy. In 2024, 68.9% of all Florida resident births occurred to mothers who began prenatal care in the first trimester. This percentage peaked in 2003 at 85.85% and has since declined.
Smoking
Smoking during pregnancy increases the risk of poor birth outcomes, such as low birth weight and preterm birth. In 1990, 16.18% of all newborns in Florida were born to mothers who smoked during pregnancy. This percentage has since declined steadily to 1.44% in 2024.
