Reducing avoidable deaths from chronic disease leads to “substantial” economic savings

A Harvard study found that the economic value of reducing avoidable deaths from cardiovascular disease alone would be between 2 and 8% of annual income in 2019 in any region of the world.

  • Chronic heart disease

American heart health is worsening

In the U.S., progress in cardiovascular health has largely stalled out and in some ways worsened—even as increasingly effective treatments and interventions come to market.

Kidneys

A newly launched startup is building upon innovations developed at Harvard to engineer functional kidney tissue for renal repair and replacement therapy.

Pancreas

Harvard Professor Doug Melton and his team are testing a new treatment that could make insulin shots obsolete.

Harvard research, which offers clues for treatment and prevention of aortic aneurysms, may also address hypertension, which affects nearly half of all adults in the U.S.

Lungs

Harvard research found for the first time common genetic factors shared between obesity and certain types of asthma.

CTE is not just caused by repeated head impact but is also linked to DNA damage similar to that seen in Alzheimer’s disease.

Ears

Harvard researchers developed a way to objectively measure tinnitus, which may help in developing future therapies.

Harvard researchers have found an increased risk of liver cancer and chronic liver disease mortality among women who consume sugar-sweetened beverages on a daily basis.

Nervous system

Harvard experts are finding novel ways to identify people at high risk of developing clinical Parkinson’s disease later in life.

A team at Harvard identified an unexpected avenue toward alleviating the symptoms of endometriosis, which has proven difficult to treat effectively.

Good habits for prevention

A healthy diet

A Harvard study shows that eating a diet rich in fruits, vegetables, whole grains, and unsaturated fats throughout midlife may increase an individual’s odds of living to at least 70 years old, being free of chronic disease, and maintaining good cognitive function, mental health, and physical function.

Moderate exercise

Harvard research showed that even light physical activity, including housework, increases one’s odds of reaching 70 free of mental health issues, physical impairments, memory issues, and chronic disease.

Less drinking, no smoking

Harvard research, including the Nurses’ Health Study, now in its fifth decade, has illuminated that reducing or eliminating alcohol and abstaining from smoking can increase years lived free of type 2 diabetes, cardiovascular disease, and cancer.
