Preventive healthcare or prophylaxis is the application of healthcare measures to prevent diseases. Disease and disability are affected by environmental factors, genetic predisposition, disease agents, and lifestyle choices, and are dynamic processes that begin before individuals realize they are affected. Disease prevention relies on anticipatory actions that can be categorized as primal, primary, secondary, and tertiary prevention.

Each year, millions of people die of preventable causes. A 2004 study showed that about half of all deaths in the United States in 2000 were due to preventable behaviors and exposures. Leading causes included cardiovascular disease, chronic respiratory disease, unintentional injuries, diabetes, and certain infectious diseases. This is an increase from the year 2000, during which 60% of deaths were attributed to these diseases. It is recommended that adults and children aim to visit their doctor for regular check-ups, even if they feel healthy, to perform disease screening, identify risk factors for disease, discuss tips for a healthy and balanced lifestyle, stay up to date with immunizations and boosters, and maintain a good relationship with a healthcare provider. In pediatrics, some common examples of primary prevention are encouraging parents to turn down the temperature of their home water heater in order to avoid scalding burns, encouraging children to wear bicycle helmets, and suggesting that people use the air quality index (AQI) to check the level of pollution in the outside air before engaging in sporting activities.

Some common disease screenings include checking for hypertension (high blood pressure), hyperglycemia (high blood sugar, a risk factor for diabetes mellitus), hypercholesterolemia (high blood cholesterol), screening for colon cancer, depression, HIV and other common types of sexually transmitted disease such as chlamydia, syphilis, and gonorrhea, mammography (to screen for breast cancer), colorectal cancer screening, a Pap test (to check for cervical cancer), and screening for osteoporosis. Genetic testing can also be performed to screen for mutations that cause genetic disorders or predisposition to certain diseases such as breast or ovarian cancer. secondary, and tertiary prevention levels.

Although advocated as preventive medicine in the early twentieth century by Sara Josephine Baker, in the 1940s, Hugh R. Leavell and E. Gurney Clark coined the term primary prevention. They worked at the Harvard and Columbia University Schools of Public Health, respectively, and later expanded the levels to include secondary and tertiary prevention. Goldston (1987) notes that these levels might be better described as "prevention, treatment, and rehabilitation", although the terms primary, secondary, and tertiary prevention are still in use today. The concept of primal prevention has been created much more recently, in relation to the new developments in molecular biology over the last fifty years, more particularly in epigenetics, which point to the paramount importance of environmental conditions, both physical and affective, on the organism during its fetal and newborn life, or so-called primal period of life.

Primal and primordial preventions

Primal prevention is health promotion par excellence. New knowledge in molecular biology, in particular epigenetics, points to how much affective as well as physical environment during fetal and newborn life may determine adult health. This way of promoting health consists mainly in providing future parents with pertinent, unbiased information on primal health and supporting them during their child's primal period of life (i.e., "from conception to first anniversary" according to definition by the Primal Health Research Centre, London). This includes adequate parental leave, ideally for both parents, with kin caregiving and financial help where needed.

Primordial prevention refers to all measures designed to prevent the development of risk factors in the first place, early in life, or prohibiting endocrine-disrupting chemicals in food-handling equipment and food contact materials.

Primary prevention

Primary prevention consists of traditional health promotion and "specific protection". Preventing disease and creating overall well-being prolongs life expectancy.

Access

Some groups are at a disadvantage when it comes to health, not because of qualities they're born with but because of socioeconomic factors they experience in life. The 2011 National Health Interview Survey performed by the Centers for Disease Control was the first national survey to include questions about ability to pay for food. Difficulty with paying for food, medicine, or both is a problem facing 1 out of 3 Americans. If better food options were available through food banks, soup kitchens, and other resources for low-income people, obesity and the chronic conditions that come along with it would be better controlled. A food desert is an area with restricted access to healthy foods due to a lack of supermarkets within a reasonable distance. These are often low-income neighborhoods with the majority of residents lacking transportation. There have been several grassroots movements since 1995 to encourage urban gardening, using vacant lots to grow food cultivated by local residents. Mobile fresh markets are another resource for residents in a "food desert", which are specially outfitted buses bringing affordable fresh fruits and vegetables to low-income neighborhoods.

Food education and guidance

It has been proposed that healthy longevity diets are included in standard healthcare as switching from a "typical Western diet" could often extend life by a decade.

Protective measures

Specific protective measures such as water purification, sewage treatment, and the development of personal hygienic routines, such as regular hand-washing, safe sex to prevent sexually transmitted infections, became mainstream upon the discovery of infectious disease agents and have decreased the rates of communicable diseases which are spread in unsanitary conditions.

Water, including drinking water, is also monitored in many cases for securing health. There also is some monitoring of air pollution. In many cases, environmental standards such as via maximum pollution levels, regulation of chemicals, occupational hygiene requirements or consumer protection regulations establish some protection in combination with the monitoring.

Preventive measures like vaccines and medical screenings are also important. Using PPE properly and getting the recommended vaccines and screenings can help decrease the spread of respiratory diseases, protecting the healthcare workers as well as their patients.

Secondary prevention

Secondary prevention identifies early stages of diseases, e.g. by using screening tests. It attempts to prevent asymptomatic disease from progressing to symptomatic disease. Secondary prevention consists of "early diagnosis and prompt treatment" to contain the disease and prevent its spread to other individuals, and "disability limitation" to prevent potential future complications and disabilities from the disease.

Leading causes of preventable death

Worldwide

The leading causes of preventable death worldwide share similar trends to the United States. There are a few differences between the two, such as malnutrition, pollution, and unsafe sanitation, that reflect health disparities between the developing and developed world.

{|class="wikitable"

|+ Leading causes of preventable death worldwide as of 2001 And another study concluded that the global mean loss of life expectancy (a measure similar to years of potential life lost) from air pollution in 2015 was 2.9 years, substantially more than, for example, 0.3 years from all forms of direct violence, albeit a significant fraction of the LLE is considered to be unavoidable (such as pollution from some natural wildfires).

A 2021 landmark study by the World Health Organization and the International Labour Organization found that exposure to long working hours is the occupational risk factor with the largest attributable burden of disease, i.e. an estimated 745,000 fatalities from ischemic heart disease and stroke events in 2016. With this study, prevention of exposure to long working hours has emerged as a priority for prevention healthcare in workplace settings.

United States

The leading preventable cause of death in the United States is tobacco; however, poor diet and lack of exercise may soon surpass tobacco as a leading cause of death. These behaviors are modifiable and public health and prevention efforts could make a difference to reduce these deaths. it was still far from the fourth Millennium Development Goal to decrease child mortality by two-thirds by 2015. Of these deaths, about 64% were due to infection including diarrhea, pneumonia, and malaria. In 2003, the World Health Organization created a list of interventions in the following table that were judged economically and operationally "feasible," based on the healthcare resources and infrastructure in 42 nations that contribute to 90% of all infant and child deaths. The table indicates how many infant and child deaths could have been prevented in 2000, assuming universal healthcare coverage. Sedentary adults should aim for at least half an hour of moderate-level daily physical activity and eventually increase to include at least 20 minutes of intense exercise, three times a week.

Sexually transmitted infections

Sexually transmitted infections (STIs), such as syphilis and HIV, are common but preventable with safe-sex practices. STIs can be asymptomatic, or cause a range of symptoms. Preventive measures for STIs are called prophylactics. The term especially applies to the use of condoms, which are highly effective at preventing disease, but also to other devices meant to prevent STIs,

Thrombosis

Thrombosis is a serious circulatory disease affecting thousands, usually older persons undergoing surgical procedures, women taking oral contraceptives and travelers. The consequences of thrombosis can be heart attacks and strokes. Prevention can include exercise, anti-embolism stockings, pneumatic devices, and pharmacological treatments.

Cancer

In recent years, cancer has become a global problem. Low and middle income countries share a majority of the cancer burden largely due to exposure to carcinogens resulting from industrialization and globalization. However, primary prevention of cancer and knowledge of cancer risk factors can reduce over one third of all cancer cases. Primary prevention of cancer can also prevent other diseases, both communicable and non-communicable, that share common risk factors with cancer. Tobacco is an environmental carcinogen and the major underlying cause of lung cancer. Both smoking and second-hand exposure from other smokers can lead to lung cancer and eventually death.

Lung cancer and tobacco smoking are increasing worldwide, especially in China. China is responsible for about one-third of the global consumption and production of tobacco products. Tobacco control policies have been ineffective as China is home to 350 million regular smokers and 750 million passive smokers and the annual death toll is over 1 million.

Skin cancer

thumb|An image of melanoma, one of the deadliest forms of skin cancer

Skin cancer is the most common cancer in the United States. The most lethal form of skin cancer, melanoma, leads to over 50,000 annual deaths in the United States. An international study reported that Australians tended to demonstrate higher knowledge of sun protection and skin cancer knowledge, compared to other countries. A 2002 case-control study in Brazil showed that only 3% of case participants and 11% of control participants used sunscreen with SPF >15.

Cervical cancer

thumb|The presence of cancer (adenocarcinoma) detected on a Pap test

Cervical cancer ranks among the top three most common cancers among women in Latin America, sub-Saharan Africa, and parts of Asia. Cervical cytology screening aims to detect abnormal lesions in the cervix so that women can undergo treatment prior to the development of cancer. Given that high quality screening and follow-up care has been shown to reduce cervical cancer rates by up to 80%, most developed countries now encourage sexually active women to undergo a Pap test every 3–5 years. Finland and Iceland have developed effective organized programs with routine monitoring and have managed to significantly reduce cervical cancer mortality while using fewer resources than unorganized, opportunistic programs such as those in the United States or Canada.

In developing nations in Latin America, such as Chile, Colombia, Costa Rica, and Cuba, both public and privately organized programs have offered women routine cytological screening since the 1970s. However, these efforts have not resulted in a significant change in cervical cancer incidence or mortality in these nations. This is likely due to low quality, inefficient testing. However, Puerto Rico, which has offered early screening since the 1960s, has witnessed almost a 50% decline in cervical cancer incidence and almost a four-fold decrease in mortality between 1950 and 1990. Brazil, Peru, India, and several high-risk nations in sub-Saharan Africa which lack organized screening programs, have a high incidence of cervical cancer. and the fourth most common cause of cancer death after lung, stomach, and liver cancer, having caused 715,000 deaths in 2010.

It is also highly preventable; about 80 percent of colorectal cancers begin as benign growths, commonly called polyps, which can be easily detected and removed during a colonoscopy. Other methods of screening for polyps and cancers include fecal occult blood testing. Lifestyle changes that may reduce the risk of colorectal cancer include increasing consumption of whole grains, fruits and vegetables, and reducing consumption of red meat.

Dementia

Health disparities and barriers to accessing care

Access to healthcare and preventive health services is unequal, as is the quality of care received. A study conducted by the Agency for Healthcare Research and Quality (AHRQ) revealed health disparities in the United States. In the United States, elderly adults (>65 years old) received worse care and had less access to care than their younger counterparts. The same trends are seen when comparing all racial minorities (black, Hispanic, Asian) to white patients, and low-income people to high-income people. Additionally, uninsured people tend to not seek care until their diseases progress to chronic and serious states and they are also more likely to forgo necessary tests, treatments, and filling prescription medications.

These sorts of disparities and barriers exist worldwide as well. Often, there are decades of gaps in life expectancy between developing and developed countries. For example, Japan has an average life expectancy that is 36 years greater than that in Malawi. Low-income countries also tend to have fewer physicians than high-income countries. In Nigeria and Myanmar, there are fewer than 4 physicians per 100,000 people while Norway and Switzerland have a ratio that is ten-fold higher.

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 for illness. In order to assess the cost-effectiveness of prevention, the cost of the preventive measure, savings from avoiding morbidity, and the cost from extending the lifespan need to be considered. Life extension costs become smaller when accounting for savings from postponing the last year of life, which makes up a large fraction of lifetime medical expenditures and becomes cheaper with age. Prevention leads to savings only if the cost of the preventive measure is less than the savings from avoiding morbidity net of the cost of extending the life span. In order to establish reliable economics of prevention for illnesses that are complicated in origin, knowing how best to assess prevention efforts, i.e. developing useful measures and appropriate scope, is required.

Effectiveness

Preventive healthcare measures increase the quality of life. There are varying views on what constitutes a "good investment." Some argue that preventive health measures should save more money than they cost, when factoring in treatment costs in the absence of such measures. Others have argued in favor of "good value" or conferring significant health benefits even if the measures do not save money. Preventive health services comprise a myriad of different services, each of which can individually lead to net costs, savings, or neither. Overall, preventive services are difficult to implement because healthcare providers have limited time with patients and must integrate a variety of preventive health measures from different sources. Similarly, it was found that the cost of drugs or dietary changes to decrease high blood cholesterol exceeded the cost of subsequent heart disease treatment. Due to these findings, some argue that rather than focusing healthcare reform efforts exclusively on preventive care, the interventions that bring about the highest level of health should be prioritized. The Diabetes Prevention Program Research Group conducted a 2012 study evaluating the costs and benefits in quality-adjusted life-years or QALYs of lifestyle changes versus taking the drug metformin. They found that neither method brought about financial savings, but were cost-effective nonetheless because they brought about an increase in QALYs. Preventive healthcare skeptics also argue that while many treatments of existing diseases involve use of advanced equipment and technology, in some cases, this would be a more efficient use of resources than attempts to prevent the disease. They each have similar goals of reducing childhood obesity. The effects of these interventions on BMI have been studied, and the cost-effectiveness analysis has led to a better understanding of projected cost reductions and improved health outcomes. The Childhood Obesity Intervention Cost-Effectiveness Study (CHOICES) was conducted to evaluate and compare the CEA of these four interventions. Furthermore, obese children have increased health care expenses (e.g. medications, acute care visits). In the long term, obese children tend to become obese adults with associated increased risk for a chronic condition such as diabetes or hypertension. Any effect on their cognitive development may also affect their contributions to society and socioeconomic status.

  1. In the CHOICES, it was noted that translating the effects of these interventions may in fact differ among communities throughout the nation. In addition it was suggested that limited outcomes are studied and these interventions may have an additional effect that is not fully appreciated.
  2. Modeling outcomes in such interventions in children over the long term is challenging because advances in medicine and medical technology are unpredictable. The projections from cost-effective analysis may need to be reassessed more frequently.

Economics of U.S. preventive care

As of 2009, the cost-effectiveness of preventive care was a highly debated topic. While some economists argue that preventive care is valuable and potentially cost saving, others believe it is a waste of resources. Preventive care is composed of a variety of clinical services and programs including annual doctor's check-ups, annual immunizations, and wellness programs; recent models show that these simple interventions can have significant economic impacts. Specifically, health assessments/screenings have cost savings potential, with varied cost-effectiveness based on screening and assessment type. Inadequate prenatal care can lead to an increased risk of prematurity, stillbirth, and infant death. Time is the ultimate resource and preventive care can help mitigate the time costs. Telehealth and telemedicine is one option that has gained consumer interest, acceptance, and confidence and can improve quality of care and patient satisfaction.

Economics for investment

There are benefits and trade-offs when considering investment in preventive care versus other types of clinical services. Preventive care can be a good investment as supported by the evidence base and can drive population health management objectives.

Preventive care transcends demographics and is applicable to people of every age. The Health Capital Theory underpins the importance of preventive care across the lifecycle and provides a framework for understanding the variances in health and health care that are experienced. It treats health as a stock that provides direct utility. Health depreciates with age and the aging process can be countered through health investments. The theory further supports that individuals demand good health, that the demand for health investment is a derived demand (i.e. investment is health is due to the underlying demand for good health), and the efficiency of the health investment process increases with knowledge (i.e. it is assumed that the more educated are more efficient consumers and producers of health).

The prevalence elasticity of demand for prevention can also provide insights into the economics. Demand for preventive care can alter the prevalence rate of a given disease and further reduce or even reverse any further growth of prevalence.

The U.S. Preventive Services Task Force (USPSTF), a panel of national experts in prevention and evidence-based medicine, works to improve health of Americans by making evidence-based recommendations about clinical preventive services. They do not consider the cost of a preventive service when determining a recommendation. Each year, the organization delivers a report to Congress that identifies critical evidence gaps in research and recommends priority areas for further review.

The National Network of Perinatal Quality Collaboratives (NNPQC), sponsored by the CDC, supports state-based perinatal quality collaboratives (PQCs) in measuring and improving upon health care and health outcomes for mothers and babies. These PQCs have contributed to improvements such as reduction in deliveries before 39 weeks, reductions in healthcare associated bloodstream infections, and improvements in the utilization of antenatal corticosteroids.

Telehealth and telemedicine has realized significant growth and development. The Center for Connected Health Policy (The National Telehealth Policy Resource Center) has produced multiple reports and policy briefs on the topic of Telehealth and Telemedicine and how they contribute to preventive services. Policy actions and provision of preventive services do not guarantee utilization. Reimbursement has remained a significant barrier to adoption due to variances in payer and state level reimbursement policies and guidelines through government and commercial payers. Americans use preventive services at about half the recommended rate and cost-sharing, such as deductibles, co-insurance, or copayments, also reduce the likelihood that preventive services will be used.

Affordable Care Act and preventive healthcare

The Patient Protection and Affordable Care Act, also known as just the Affordable Care Act or Obamacare, was passed and became law in the United States on March 23, 2010. The finalized and newly ratified law was to address many issues in the U.S. healthcare system, which included expansion of coverage, insurance market reforms, better quality, and the forecast of efficiency and costs. Under the insurance market reforms the act required that insurance companies no longer exclude people with pre-existing conditions, allow for children to be covered on their parents' plan until the age of 26, and expand appeals that dealt with reimbursement denials. The Affordable Care Act also banned the limited coverage imposed by health insurances, and insurance companies were to include coverage for preventive health care services. The U.S. Preventive Services Task Force has categorized and rated preventive health services as either A or B, as to which insurance companies must comply and present full coverage. Not only has the U.S. Preventive Services Task Force provided graded preventive health services that are appropriate for coverage, they have also provided many recommendations to clinicians and insurers to promote better preventive care to ultimately provide better quality of care and lower the burden of costs.

Health insurance

Healthcare insurance companies are willing to pay for preventive care despite the fact that patients are not acutely sick in hope that it will prevent them from developing a chronic disease later on in life. Today, health insurance plans offered through the Marketplace, mandated by the Affordable Care Act are required to provide certain preventive care services free of charge to patients. Section 2713 of the Affordable Care Act, specifies that all private Marketplace and all employer-sponsored private plans (except those grandfathered in) are required to cover preventive care services that are ranked A or B by the U.S. Preventive Services Task Force free of charge to patients. UnitedHealthcare insurance company has published patient guidelines at the beginning of the year explaining their preventive care coverage.

Evaluating incremental benefits

Evaluating the incremental benefits of preventive care requires a longer period of time when compared to acutely ill patients. Inputs into the model such as discounting rate and time horizon can have significant effects on the results. One controversial subject is use of a 10-year time frame to assess cost effectiveness of diabetes preventive services by the US Congressional Budget Office.

Preventive care services mainly focus on chronic disease. The Congressional Budget Office has provided guidance that further research is needed in the area of the economic impacts of obesity in the U.S. before the CBO can estimate budgetary consequences. A bipartisan report published in May 2015 recognizes the potential of preventive care to improve patients' health at individual and population levels while decreasing the healthcare expenditure.

Economic case

Mortality from modifiable risk factors

Chronic diseases such as heart disease, stroke, diabetes, obesity and cancer have become the most common and costly health problems in the United States. In 2014, it was projected that by 2023 the number of chronic disease cases would increase by 42%, resulting in $4.2 trillion in treatment and lost economic output. They are also among the top ten leading causes of mortality. Chronic diseases are driven by risk factors that are largely preventable. Sub-analysis performed on all deaths in the United States in 2000 revealed that almost half were attributed to preventable behaviors including tobacco use, poor diet, physical inactivity and alcohol consumption. Modifiable risk factors are also responsible for a large morbidity burden, resulting in poor quality of life in the present and loss of future life earning years. It is further estimated that by 2023, focused efforts on the prevention and treatment of chronic disease may result in 40 million fewer chronic disease cases, potentially reducing treatment costs by $220 billion. The economic benefits of childhood vaccination extend beyond individual patients to insurance plans and vaccine manufacturers, all while improving the health of the population.

Health capital theory

The burden of preventable illness extends beyond the healthcare sector, incurring costs related to lost productivity among workers in the workforce. Indirect costs related to poor health behaviors and associated chronic disease costs U.S. employers billions of dollars each year.

According to the American Diabetes Association (ADA), medical costs for employees with diabetes are twice as high as for workers without diabetes and are caused by work-related absenteeism ($5 billion), reduced productivity at work ($20.8 billion), inability to work due to illness-related disability ($21.6 billion), and premature mortality ($18.5 billion). Reported estimates of the cost burden due to increasingly high levels of overweight and obese members in the workforce vary, with best estimates suggesting 450 million more missed work days, resulting in $153 billion each year in lost productivity, according to the CDC Healthy Workforce.

The health capital model explains how individual investments in health can increase earnings by "increasing the number of healthy days available to work and to earn income." In this context, health can be treated both as a consumption good, wherein individuals desire health because it improves quality of life in the present, and as an investment good because of its potential to increase attendance and workplace productivity over time. Preventive health behaviors such as healthful diet, regular exercise, access to and use of well-care, avoiding tobacco, and limiting alcohol can be viewed as health inputs that result in both a healthier workforce and substantial cost savings.

Quality-adjusted life years

Health benefits of preventive care measures can be described in terms of quality-adjusted life-years (QALYs) saved. A QALY takes into account length and quality of life, and is used to evaluate the cost-effectiveness of medical and preventive interventions. Classically, one year of perfect health is defined as 1 QALY and a year with any degree of less than perfect health is assigned a value between 0 and 1 QALY. As an economic weighting system, the QALY can be used to inform personal decisions, to evaluate preventive interventions and to set priorities for future preventive efforts.

Cost-saving and cost-effective benefits of preventive care measures are well established. The Robert Wood Johnson Foundation evaluated the prevention cost-effectiveness literature, and found that many preventive measures meet the benchmark of <$100,000 per QALY and are considered to be favorably cost-effective. These include screenings for HIV and chlamydia, cancers of the colon, breast and cervix, vision screening, and screening for abdominal aortic aneurysms in men >60 in certain populations. Alcohol and tobacco screening were found to be cost-saving in some reviews and cost-effective in others. According to the RWJF analysis, two preventive interventions were found to save costs in all reviews: childhood immunizations and counseling adults on the use of aspirin.

Minority populations

Health disparities are increasing in the United States for chronic diseases such as obesity, diabetes, cancer, and cardiovascular disease. Populations at heightened risk for health inequities are the growing proportion of racial and ethnic minorities, including African Americans, American Indians, Hispanics/Latinos, Asian Americans, Alaska Natives and Pacific Islanders.

According to the Racial and Ethnic Approaches to Community Health (REACH), a national CDC program, non-Hispanic blacks currently have the highest rates of obesity (48%), and risk of newly diagnosed diabetes is 77% higher among non-Hispanic blacks, 66% higher among Hispanics/Latinos and 18% higher among Asian Americans compared to non-Hispanic whites. Current U.S. population projections predict that more than half of Americans will belong to a minority group by 2044. Without targeted preventive interventions, medical costs from chronic disease inequities will become unsustainable. Broadening health policies designed to improve delivery of preventive services for minority populations may help reduce substantial medical costs caused by inequities in health care, resulting in a return on investment.

Policies

Chronic disease is a population-level issue that requires population-level efforts and national- and state-level public policy to effectively prevent, rather than individual-level efforts. The United States currently employs many public health policy efforts aligned with the preventive health efforts discussed above. The Centers for Disease Control and Prevention support initiatives such as Health in All Policies and HI-5 (Health Impact in 5 Years), and collaborative efforts that aim to consider prevention across sectors and address social determinants of health as a method of primary prevention for chronic disease.

Obesity

Policies that address the obesity epidemic should be proactive and far-reaching, including a variety of stakeholders both in healthcare and in other sectors. Recommendations from the Institute of Medicine in 2012 suggest that "concerted action be taken across and within five environments (physical activity (PA), food and beverage, marketing and messaging, healthcare and worksites, and schools) and all sectors of society (including government, business and industry, schools, child care, urban planning, recreation, transportation, media, public health, agriculture, communities, and home) in order for obesity prevention efforts to truly be successful."

There are dozens of current policies acting at either (or all of) the federal, state, local and school levels. Most states employ a physical education requirement of 150 minutes of physical education per week at school, a policy of the National Association of Sport and Physical Education. In some cities, including Philadelphia, a sugary food tax is employed. This is a part of an amendment to Title 19 of the Philadelphia Code, "Finance, Taxes and Collections", Chapter 19-4100, Sugar-Sweetened Beverage Tax that was approved 2016, which establishes an excise tax of $0.015 per fluid ounce on distributors of beverages sweetened with both caloric and non-caloric sweeteners. Distributors are required to file a return with the department, and the department can collect taxes, among other responsibilities. These policies can be a source of tax credits. Under the Philadelphia policy, businesses can apply for tax credits with the revenue department on a first-come, first-served basis. This applies until the total amount of credits for a particular year reaches one million dollars.

Recently, advertisements for food and beverages directed at children have received much attention. The Children's Food and Beverage Advertising Initiative (CFBAI) is a self-regulatory program of the food industry. Each participating company makes a public pledge that details its commitment to advertise only foods that meet certain nutritional criteria to children under 12 years old. This is a self-regulated program with policies written by the Council of Better Business Bureaus. The Robert Wood Johnson Foundation funded research to test the efficacy of the CFBAI. The results showed progress in terms of decreased advertising of food products that target children and adolescents.

Childhood immunization policies

Despite nationwide controversies over childhood vaccination and immunization, there are policies and programs at the federal, state, local and school levels outlining vaccination requirements. All states require children to be vaccinated against certain communicable diseases as a condition for school attendance. However, only 18 states allow exemptions for "philosophical or moral reasons." Diseases for which vaccinations form part of the standard ACIP vaccination schedule are diphtheria tetanus pertussis (whooping cough), poliomyelitis (polio), measles, mumps, rubella, haemophilus influenzae type b, hepatitis B, influenza, and pneumococcal infections. The CDC website maintains such schedules.

The CDC website describes a federally funded program, Vaccines for Children (VFC), which provides vaccines at no cost to children who might not otherwise be vaccinated because of inability to pay. Additionally, the Advisory Committee on Immunization Practices (ACIP) is an expert vaccination advisory board that informs vaccination policy and guides on-going recommendations to the CDC, incorporating the most up-to-date cost-effectiveness and risk-benefit evidence in its recommendations.
