In 2017, the Behavioral Risk Factor Survey (BRFS) found that hypertension (34.9%) and high cholesterol (34.6%) were the most prevalent chronic diseases in the State of Delaware, affecting nearly one third of Delaware’s population.

Other reports from the BRFS include:

  • Arthritis. About one quarter of the adult population reported being diagnosed with arthritis.
  • Asthma. About 15.8% have been told they had asthma (10.6% of the population had asthma in 2017). Women were more affected than men.
  • Cancer. About 6.9% of Delaware adults stated they had been diagnosed with skin cancer, and 7.7% said they had another kind of cancer.
  • Depression. 19.7% of Delaware adults have been diagnosed with a depressive disorder.
  • Heart Disease. 6.4% of adults said they had been diagnosed with coronary heart disease, or had had a heart attack.
  • Kidney Disease. More than 3% of adult Delawareans reported being diagnosed with kidney disease at some time.

According to Delaware TODAY, there were nearly 480,000 cases of cancers, diabetes, heart disease, hypertension, stroke, mental disorders and pulmonary conditions reported in the first state in 2003.  These conditions “shorten lives, reduce quality of life, and create caregiver burden.”
