SGIM News:A team of researchers from Cleveland Clinic and New York University School of Medicine have found that based on 2014 data, obesity resulted in as much as 47 percent more life-years lost than tobacco, and tobacco caused similar life-years lost as high blood pressure.
Preliminary work presented by Cleveland Clinic today at the 2017 Society of General Internal Medicine Annual Meeting analyzed the contribution of modifiable behavioral risk factors to causes-of-death in the US population.
Based on this preliminary work, the team found the greatest number of preventable life-years lost were due to (in order from greatest to least) obesity, diabetes, tobacco use, high blood pressure and high cholesterol. However, researchers also noted that some individuals may have needs that are very different than those of the broader U.S. population.
For an obese and alcoholic patient, for example, alcohol use may be more important to address than obesity, even though obesity has a greater impact on the population.
Results highlight the clinical and public health achievement of smoking cessation efforts because 15 years ago, tobacco would have topped the list.
“Modifiable behavioral risk factors pose a substantial mortality burden in the U.S.,” said Glen Taksler, Ph.D., internal medicine researcher from Cleveland Clinic and lead author of the study. “These preliminary results continue to highlight the importance of weight loss, diabetes management and healthy eating in the U.S. population.”
A key takeaway is that three (diabetes, hypertension and high cholesterol) of the top five causes of death can be treated, so helping patients understand treatment options and approaches can have a powerful impact on life-years. The results also highlight the importance of preventive care in clinical practice and why it should be a priority for physicians.
To estimate the number of life-years lost to each modifiable risk factor, researchers examined the change in mortality for a series of hypothetical U.S. populations that each eliminated a single risk factor. They compared the results with the change in life-years lost for an “optimal” population that eliminated all modifiable risk factors.
Recognizing that some less common factors might place substantial burden on small population subgroups, they also estimated life expectancy gained in individuals with each modifiable risk factor.
“The reality is, while we may know the proximate cause of a patient’s death, for example, breast cancer or heart attack, we don’t always know the contributing factor(s), such as tobacco use, obesity, alcohol and family history. For each major cause of death, we identified a root cause to understand whether there was a way a person could have lived longer.”
Dr. Taksler and colleagues are continuing to conduct research in this area, and analyze and refine results.
About Cleveland Clinic
Cleveland Clinic is a nonprofit multispecialty academic medical center that integrates clinical and hospital care with research and education. Located in Cleveland, Ohio, it was founded in 1921 by four renowned physicians with a vision of providing outstanding patient care based upon the principles of cooperation, compassion and innovation.
Cleveland Clinic has pioneered many medical breakthroughs, including coronary artery bypass surgery and the first face transplant in the United States. U.S. News & World Report consistently names Cleveland Clinic as one of the nation’s best hospitals in its annual “America’s Best Hospitals” survey. Among Cleveland Clinic’s 51,000 employees are more than 3,500 full-time salaried physicians and researchers and 14,000 nurses, representing 140 medical specialties and subspecialties.
Cleveland Clinic’s health system includes a 165-acre main campus near downtown Cleveland, 10 regional hospitals, more than 150 northern Ohio outpatient locations – including 18 full-service family health centers and three health and wellness centers – and locations in Weston, Fla.; Las Vegas, Nev.; Toronto, Canada; Abu Dhabi, UAE; and London, England. In 2016, there were 7.1 million outpatient visits, 161,674 hospital admissions and 207,610 surgical cases throughout Cleveland Clinic’s health system. Patients came for treatment from every state and 180 countries.
