The researchers’ county-by-county data — measuring information in both Florida and other states through 2015 — show that good health is affected by many factors beyond medical care, including housing, education, jobs and access to healthy foods.

“The data compiled in the rankings serve as a reminder that many factors beyond health care influence one’s health, and the county profiles help communities determine whether their local efforts are improving the health of their residents,” said State Surgeon General and Secretary Dr. Celeste Philip.

For this year’s rankings, researchers said they took a closer look at premature deaths — those among people under 75 years old. In Florida, they found 46 counties have experienced improvements in premature death rates, while two have seen worsening rates and the rest saw no change.

Nationally, drug overdoses are fueling a dramatic increase in premature deaths among 15- to 44-years-old , researchers found.

Their report concluded that “the drug overdose epidemic is the leading cause of death among 25- to 44-years-old and is a clear driver of this trend.”
