Economics of lifestyle-based prevention With lifestyle factors such as diet and exercise rising to the top of preventable death statistics, the economics of healthy lifestyle is a growing concern. There is little question that positive lifestyle choices provide an investment in health throughout life. To gauge success, traditional measures such as the quality years of life method (QALY), show great value. However, that method does not account for the cost of chronic conditions or future lost earnings because of poor health. Developing future economic models that would guide both private and public investments as well as drive future policy to evaluate the efficacy of positive lifestyle choices on health is a major topic for economists globally. Americans spend over three trillion a year on health care but have a higher rate of infant mortality, shorter life expectancies, and a higher rate of diabetes than other high-income nations because of negative lifestyle choices. Despite these large costs, very little is spent on prevention for lifestyle-caused conditions in comparison. In 2016, the Journal of the American Medical Association estimated that $101 billion was spent in 2013 on the preventable disease of diabetes, and another $88 billion was spent on heart disease. In an effort to encourage healthy lifestyle choices, as of 2010 workplace wellness programs were on the rise but the economics and effectiveness data were continuing to evolve and develop. Health insurance coverage impacts lifestyle choices, even intermittent loss of coverage had negative effects on healthy choices in the U.S. The repeal of the Affordable Care Act (ACA) could significantly impact coverage for many Americans as well as "The Prevention and Public Health Fund" which is the U.S. first and only mandatory funding stream dedicated to improving public health including counseling on lifestyle prevention issues, such as weight management, alcohol use, and treatment for depression. Because in the U.S. chronic illnesses predominate as a cause of death and pathways for treating chronic illnesses are complex and multifaceted, prevention is a best practice approach to chronic disease when possible. In many cases, prevention requires mapping complex pathways to determine the ideal point for intervention. Cost-effectiveness of prevention is achievable, but impacted by the length of time it takes to see effects/outcomes of intervention. This makes prevention efforts difficult to fund—particularly in strained financial contexts. Prevention potentially creates other costs as well, due to extending the lifespan and thereby increasing opportunities
