Relationship of Childhood Abuse and Household Dysfunction to Many of the Leading Causes of Death in Adults The Adverse Childhood Experiences (ACE) Study

Vincent J. Felitti, MD, FACP, Robert F. Anda, MD, MS, Dale Nordenberg, MD, David F. Williamson, MS, PhD, Alison M. Spitz, MS, MPH, Valerie Edwards, BA, Mary P. Koss, PhD, James S. Marks, MD, MPH

Background: The relationship of health risk behavior and disease in adulthood to the breadth of exposure to childhood emotional, physical, or sexual abuse, and household dysfunction during childhood has not previously been described.

Methods: A questionnaire about adverse childhood experiences was mailed to 13,494 adults who had completed a standardized medical evaluation at a large HMO; 9,508 (70.5%) responded. Seven categories of adverse childhood experiences were studied: psychological, physical, or sexual abuse; violence against mother; or living with household members who were substance abusers, mentally ill or suicidal, or ever imprisoned. The number of categories of these adverse childhood experiences was then compared to measures of adult risk behavior, health status, and disease. Logistic regression was used to adjust for effects of demographic factors on the association between the cumulative number of categories of childhood exposures (range: 0–7) and risk factors for the leading causes of death in adult life.

Results: More than half of respondents reported at least one, and one-fourth reported $2 categories of childhood exposures. We found a graded relationship between the number of categories of childhood exposure and each of the adult health risk behaviors and diseases that were studied (P , .001). Persons who had experienced four or more categories of childhood exposure, compared to those who had experienced none, had 4- to 12-fold increased health risks for alcoholism, drug abuse, depression, and suicide attempt; a 2- to 4-fold increase in smoking, poor self-rated health, $50 sexual intercourse partners, and sexually transmitted disease; and a 1.4- to 1.6-fold increase in physical inactivity and severe obesity. The number of categories of adverse childhood exposures showed a graded relationship to the presence of adult diseases including ischemic heart disease, cancer, chronic lung disease, skeletal fractures, and liver disease. The seven categories of adverse childhood experiences were strongly interrelated and persons with multiple categories of childhood exposure were likely to have multiple health risk factors later in life.

Conclusions: We found a strong graded relationship between the breadth of exposure to abuse or household dysfunction during childhood and multiple risk factors for several of the leading causes of death in adults.

Introduction

Only recently have medical investigators in pri-mary care settings begun to examine associa-tions between childhood abuse and adult health risk behaviors and disease.1–5 These associations are important because it is now clear that the leading causes of morbidity and mortality in the United States6

are related to health behaviors and lifestyle factors; these factors have been called the “actual” causes of death.7 Insofar as abuse and other potentially damaging childhood experiences contribute to the development of these risk factors, then these childhood exposures should be recog- nized as the basic causes of morbidity and mortality in adult life.

Although sociologists and psychologists have published numerous articles about the frequency8–12 and long-term consequenc- es13–15 of childhood abuse, understanding their rele- vance to adult medical problems is rudimentary. Fur- thermore, medical research in this field has limited relevance to most primary care physicians because it is focused on adolescent health,16–20 mental health in adults,20 or on symptoms among patients in specialty clinics.22,23 Studies of the long-term effects of child- hood abuse have usually examined single types of abuse, particularly sexual abuse, and few have assessed the im- pact of more than one type of abuse.5,24–28 Conditions such as drug abuse, spousal violence, and criminal activity in the household may co-occur with specific forms of abuse that involve children. Without measuring these household factors as well, long-term influence might be wrongly attributed solely to single types of abuse and the cumulative influence of multiple categories of adverse childhood experiences would not be assessed. To our knowledge, the relationship of adult health risk behaviors, health status, and disease states to childhood abuse and household dysfunction29–35 has not been described.

We undertook the Adverse Childhood Experiences (ACE) Study in a primary care setting to describe the long-term relationship of childhood experiences to important medical and public health problems. The ACE Study is assessing, retrospectively and prospec- tively, the long-term impact of abuse and household dysfunction during childhood on the following out- comes in adults: disease risk factors and incidence, quality of life, health care utilization, and mortality. In this initial paper we use baseline data from the study to provide an overview of the prevalence and interrelation of exposures to childhood abuse and household dys- function. We then describe the relationship between the number of categories of these deleterious child- hood exposures and risk factors and those diseases that

underlie many of the leading causes of death in adults.6,7,36,37

Methods Study Setting

The ACE Study is based at Kaiser Permanente’s San Diego Health Appraisal Clinic. More than 45,000 adults undergo standardized examinations there each year, making this clinic one of the nation’s largest free-

standing medical evaluation centers. All en- rollees in the Kaiser Health Plan in San Diego are advised through sales literature about the services (free for members) at the clinic; after enrollment, members are ad- vised again of its availability through new- member literature. Most members obtain appointments by self-referral; 20% are re-

ferred by their health care provider. A recent review of membership and utilization records among Kaiser members in San Diego continuously enrolled between 1992 and 1995 showed that 81% of those 25 years and older had been evaluated in the Health Appraisal Clinic.

Health appraisals include completion of a standard- ized medical questionnaire that requests demographic and biopsychosocial information, review of organ sys- tems, previous medical diagnoses, and family medical history. A health care provider completes the medical history, performs a physical examination, and reviews the results of laboratory tests with the patient.

Survey Methods

The ACE Study protocol was approved by the Institu- tional Review Boards of the Southern California Per- manente Medical Group (Kaiser Permanente), the Emory University School of Medicine, and the Office of Protection from Research Risks, National Institutes of Health. All 13,494 Kaiser Health Plan members who completed standardized medical evaluations at the Health Appraisal Clinic between August–November of 1995 and January–March of 1996 were eligible to participate in the ACE Study. Those seen at the clinic during December were not included because survey response rates are known to be lower during the holiday period.38

In the week after visiting the clinic, and hence having their standardized medical history already completed, members were mailed the ACE Study questionnaire that included questions about child- hood abuse and exposure to forms of household dysfunction while growing up. After second mailings of the questionnaire to persons who did not respond to the first mailing, the response rate for the survey was 70.5% (9,508/13,494).

A second survey wave of approximately the same number of patients as the first wave was conducted between June and October of 1997. The data for the second survey wave is currently being compiled for analysis. The methods for the second mail survey wave were identical to the first survey wave as described above. The second wave was done to enhance the precision of future detailed analyses on special topics and to reduce the time necessary to obtain precise statistics on follow-up health events. An overview of the total ACE Study design is provided in Figure 1.

Comparison of Respondents and Nonrespondents

We abstracted the completed medical evaluation for every person eligible for the study; this included their medical history, laboratory results, and physical find- ings. Respondent (n 5 9,508) and nonrespondent (n 5 3,986) groups were similar in their percentages of women (53.7% and 51.0%, respectively) and in their mean years of education (14.0 years and 13.6 years, respectively). Respondents were older than nonrespon- dents (means 56.1 years and 49.3 years) and more likely to be white (83.9% vs. 75.3%) although the actual magnitude of the differences was small.

Respondents and nonrespondents did not differ with regard to their self-rated health, smoking, other sub- stance abuse, or the presence of common medical conditions such as a history of heart attack or stroke, chronic obstructive lung disease, hypertension, or dia- betes, or with regard to marital status or current family, marital, or job-related problems (data not shown). The health appraisal questionnaire used in the clinic con-

tains a single question about childhood sexual abuse that reads “As a child were you ever raped or sexually molested?” Respondents were slightly more likely to answer affirmatively than nonrespondents (6.1% vs. 5.4%, respectively).

Questionnaire Design

We used questions from published surveys to construct the ACE Study questionnaire. Questions from the Con- flicts Tactics Scale39 were used to define psychological and physical abuse during childhood and to define violence against the respondent’s mother. We adapted four questions from Wyatt40 to define contact sexual abuse during childhood. Questions about exposure to alcohol or drug abuse during childhood were adapted from the 1988 National Health Interview Survey.41 All of the questions we used in this study to determine childhood experiences were introduced with the phrase “While you were growing up during your first 18 years of life . . .”

Questions about health-related behaviors and health problems were taken from health surveys such as the Behavioral Risk Factor Surveys42 and the Third Na- tional Health and Nutrition Examination Survey,43

both of which are directed by the Centers for Disease Control and Prevention. Questions about depression came from the Diagnostic Interview Schedule of the National Institute of Mental Health (NIMH).44 Other information for this analysis such as disease history was obtained from the standardized questionnaire used in the Health Appraisal Clinic. (A copy of the question- naires used in this study may be found at www.elsevier. com/locate/amepre.)

Defining Childhood Exposures

We used three categories of childhood abuse: psycho- logical abuse (2 questions), physical abuse (2 ques- tions), or contact sexual abuse (4 questions). There were four categories of exposure to household dysfunc- tion during childhood: exposure to substance abuse (defined by 2 questions), mental illness (2 questions), violent treatment of mother or stepmother (4 ques- tions), and criminal behavior (1 question) in the house- hold. Respondents were defined as exposed to a cate- gory if they responded “yes” to 1 or more of the questions in that category. The prevalence of positive responses to the individual questions and the category prevalences are shown in Table 1.

We used these 7 categories of childhood exposures to abuse and household dysfunction for our analysis. The measure of childhood exposure that we used was simply the sum of the categories with an exposure; thus the possible number of exposures ranged from 0 (unex- posed) to 7 (exposed to all categories).

Risk Factors and Disease Conditions Assessed

Using information from both the study questionnaire and the Health Appraisal Clinic’s questionnaire, we chose 10 risk factors that contribute to the leading causes of morbidity and mortality in the United States.6,7,36,37 The risk factors included smoking, severe obesity, physical inactivity, depressed mood, suicide attempts, alcoholism, any drug abuse, parenteral drug abuse, a high lifetime number of sexual partners ($50), and a history of having a sexually transmitted disease.

We also assessed the relationship between childhood exposures and disease conditions that are among the leading causes of mortality in the United States.6 The presence of these disease conditions was based upon medical histories that patients provided in response to the clinic questionnaire. We included a history of ischemic heart disease (including heart attack or use of nitroglycerin for exertional chest pain), any cancer, stroke, chronic bronchitis, or emphysema (COPD),

diabetes, hepatitis or jaundice, and any skeletal frac- tures (as a proxy for risk of unintentional injuries). We also included responses to the following question about self-rated health: “Do you consider your physical health to be excellent, very good, good, fair, or poor?” because it is strongly predictive of mortality.45

Definition of Risk Factors

We defined severe obesity as a body mass index (kg/ meter2) $35 based on measured height and weight; physical inactivity as no participation in recreational physical activity in the past month; and alcoholism as a “Yes” response to the question “Have you ever consid- ered yourself to be an alcoholic?” The other risk factors that we assessed are self-explanatory.

Exclusions from Analysis

Of the 9,508 survey respondents, we excluded 51 (0.5%) whose race was unstated and 34 (0.4%) whose educational attainment was not reported. We also ex- cluded persons who did not respond to certain ques- tions about adverse childhood experiences. This in- volved the following exclusions: 125 (1.3%) for household substance abuse, 181 (1.9%) for mental illness in the home, 148 (1.6%) for violence against mother, 7 (0.1%) for imprisonment of a household member, 109 (1.1%) for childhood psychological abuse, 44 (0.5%) for childhood physical abuse, and 753 (7.9%) for childhood sexual abuse. After these exclu- sions, 8,056 of the original 9,508 survey respondents (59.7% of the original sample of 13,494) remained and were included in the analysis. Procedures for insuring that the findings based on complete data were gener- alizable to the entire sample are described below.

The mean age of the 8,506 persons included in this analysis was 56.1 years (range: 19–92 years); 52.1% were women; 79.4% were white. Forty-three percent had graduated from college; only 6.0% had not graduated from high school.

Statistical Analysis

We used the Statistical Analysis System (SAS)46 for our analyses. We used the direct method to age-adjust the prevalence estimates. Logistic regression analysis was employed to adjust for the potential confounding ef- fects of age, sex, race, and educational attainment on the relationship between the number of childhood exposures and health problems.

To test for a dose-response relationship to health problems, we entered the number of childhood expo- sures as a single ordinal variable (0, 1, 2, 3, 4, 5, 6, 7) into a separate logistic regression model for each risk factor or disease condition.

Assessing the Possible Influence of Exclusions

To determine whether our results were influenced by excluding persons with incomplete information on any of the categories of childhood exposure, we performed a separate sensitivity analysis in which we included all persons with complete demographic information but assumed that persons with missing information for a category of childhood exposure did not have an expo- sure in that category.

Results Adverse Childhood Exposures

The level of positive responses for the 17 questions included in the seven categories of childhood exposure ranged from 3.0% for a respondent’s mother (or stepmother) having been threatened with or hurt by a gun or knife to 23.5% for having lived with a problem drinker or alcoholic (Table 1). The most prevalent of the 7 categories of childhood exposure was substance abuse in the household (25.6%); the least prevalent exposure category was evidence of criminal behavior in the household (3.4%). More than half of respondents (52%) experienced $1 category of adverse childhood exposure; 6.2% reported $4 exposures.

Relationships between Categories of Childhood Exposure

The probability that persons who were exposed to any single category of exposure were also exposed to an- other category is shown in Table 2. The relationship between single categories of exposure was significant for all comparisons (P , .001; chi-square). For persons reporting any single category of exposure, the proba- bility of exposure to any additional category ranged from 65%–93% (median: 80%); similarly, the probabil- ity of $2 additional exposures ranged from 40%–74% (median: 54.5%).

The number of categories of childhood exposures by demographic characteristics is shown in Table 3. Statis- tically, significantly fewer categories of exposure were found among older persons, white or Asian persons, and college graduates (P , .001). Because age is associated with both the childhood exposures as well as many of the health risk factors and disease outcomes, all prevalence estimates in the tables are adjusted for age.

Relationship between Childhood Exposures and Health Risk Factors

Both the prevalence and risk (adjusted odds ratio) increased for smoking, severe obesity, physical inactiv- ity, depressed mood, and suicide attempts as the num- ber of childhood exposures increased (Table 4). When

Am J Prev Med 1998;14(4) 249

persons with 4 categories of exposure were compared to those with none, the odds ratios ranged from 1.3 for physical inactivity to 12.2 for suicide attempts (Table 4).

Similarly, the prevalence and risk (adjusted odds ratio) of alcoholism, use of illicit drugs, injection of illicit drugs, $50 intercourse partners, and history of a sexually transmitted disease increased as the number of childhood exposures increased (Table 5). In compar- ing persons with $4 childhood exposures to those with none, odds ratios ranged from 2.5 for sexually trans- mitted diseases to 7.4 for alcoholism and 10.3 for injected drug use.

Childhood Exposures and Clustering of Health Risk Factors

We found a strong relationship between the number of childhood exposures and the number of health risk factors for leading causes of death in adults (Table 6). For example, among persons with no childhood expo- sures, 56% had none of the 10 risk factors whereas only 14% of persons with $4 categories of childhood expo- sure had no risk factors. By contrast, only 1% of persons with no childhood exposures had four or more risk factors, whereas 7% of persons with $4 childhood exposures had four or more risk factors (Table 6).

Relationship between Childhood Exposures and Disease Conditions

When persons with 4 or more categories of childhood exposure were compared to those with none, the odds ratios for the presence of studied disease con- ditions ranged from 1.6 for diabetes to 3.9 for chronic bronchitis or emphysema (Table 7). Simi- larly, the odds ratios for skeletal fractures, hepatitis or jaundice, and poor self-rated health were 1.6, 2.3, and 2.2, respectively (Table 8).

Significance of Dose-Response Relationships

In logistic regression models (which included age, gender, race, and educational attainment as covariates) we found a strong, dose-response relationship between the number of childhood exposures and each of the 10 risk factors for the leading causes of death that we studied (P , .001). We also found a significant (P , .05) dose-response relationship between the number of childhood exposures and the following disease con- ditions: ischemic heart disease, cancer, chronic bron- chitis or emphysema, history of hepatitis or jaundice, skeletal fractures, and poor self-rated health. There was no statistically significant dose-response relationship for a history of stroke or diabetes.T

Assessment of the Influence of Exclusions

In the sensitivity analysis where missing information for a category of childhood exposure was considered as no exposure, the direction and strength of the associations between the number of childhood exposures and the risk factors and disease conditions were nearly identical (data not shown). Thus, the results we present appear to be unaffected by our decision to exclude persons for whom information on any category of childhood expo- sure was incomplete.

Discussion

We found a strong dose response relationship between the breadth of exposure to abuse or household dysfunc- tion during childhood and multiple risk factors for several of the leading causes of death in adults. Disease conditions including ischemic heart disease, cancer, chronic lung disease, skeletal fractures, and liver dis- ease, as well as poor self-rated health also showed a graded relationship to the breadth of childhood expo- sures. The findings suggest that the impact of these adverse childhood experiences on adult health status is strong and cumulative.

The clear majority of patients in our study who were exposed to one category of childhood abuse or house- hold dysfunction were also exposed to at least one other. Therefore, researchers trying to understand the long-term health implications of childhood abuse may benefit from considering a wide range of related ad- verse childhood exposures. Certain adult health out-

comes may be more strongly related to unique combi- nations or the intensity of adverse childhood exposures than to the total breadth of exposure that we used for our analysis. However, the analysis we present illustrates the need for an overview of the net effects of a group of complex interactions on a wide range of health risk behaviors and diseases.

Several potential limitations need to be considered when interpreting the results of this study. The data about adverse childhood experiences are based on self-report, retrospective, and can only demonstrate associations between childhood exposures and health risk behaviors, health status, and diseases in adulthood. Second, some persons with health risk behaviors or diseases may have been either more, or less, likely to report adverse childhood experiences. Each of these issues potentially limits inferences about causality. Fur- thermore, disease conditions could be either over- or under-reported by patients when they complete the medical questionnaire. In addition, there may be me- diators of the relationship between childhood experi- ences and adult health status other than the risk factors we examined. For example, adverse childhood experi- ences may affect attitudes and behaviors toward health and health care, sensitivity to internal sensations, or physiologic functioning in brain centers and neuro- transmitter systems. A more complete understanding of these issues is likely to lead to more effective ways to address the long-term health problems associated with childhood abuse and household dysfunction.

However, our estimates of the prevalence of child-

hood exposures are similar to estimates from nationally representative surveys, indicating that the experiences of our study participants are comparable to the larger population of U.S. adults. In our study, 23.5% of participants reported having grown up with an alcohol abuser; the 1988 National Health Interview Survey estimated that 18.1% of adults had lived with an alcohol abuser during childhood.41 Contact sexual abuse was reported by 22% of respondents (28% of women and 16% of men) in our study. A national telephone survey of adults in 1990 using similar criteria for sexual abuse estimated that 27% of women and 16% of men had been sexually abused.12

There are several reasons to believe that our esti- mates of the long-term relationship between adverse childhood experiences and adult health are conserva- tive. Longitudinal follow-up of adults whose childhood abuse was well documented has shown that their retro- spective reports of childhood abuse are likely to under-

estimate actual occurrence.47,48 Underestimates of childhood exposures would result in downwardly bi- ased estimates of the relationships between childhood exposures and adult health risk behaviors and dis- eases. Another potential source of underestimation of the strength of these relationships is the lower number of childhood exposures reported by older persons in our study. This may be an artifact caused by premature mortality in persons with multiple adverse childhood exposures; the clustering of mul- tiple risk factors among persons with multiple child- hood exposures is consistent with this hypothesis. Thus, the true relationships between adverse child- hood exposures and adult health risk behaviors, health status, and diseases may be even stronger than those we report.

An essential question posed by our observations is, “Exactly how are adverse childhood experiences linked to health risk behaviors and adult diseases?” The link-

ing mechanisms appear to center on behaviors such as smoking, alcohol or drug abuse, overeating, or sexual behaviors that may be consciously or unconsciously used because they have immediate pharmacological or psychological benefit as coping devices in the face of the stress of abuse, domestic violence, or other forms of

family and household dysfunction. High levels of expo- sure to adverse childhood experiences would expect- edly produce anxiety, anger, and depression in chil- dren. To the degree that behaviors such as smoking, alcohol, or drug use are found to be effective as coping devices, they would tend to be used chronically. For

example, nicotine is recognized as having beneficial psychoactive effects in terms of regulating affect49 and persons who are depressed are more likely to smoke.50,51 Thus, persons exposed to adverse child- hood experiences may benefit from using drugs such as nicotine to regulate their mood.49,52

Consideration of the positive neuroregulatory effects of health-risk behaviors such as smoking may provide biobehavioral explanations53 for the link between ad- verse childhood experiences and health risk behaviors and diseases in adults. In fact, we found that exposure to higher numbers of categories of adverse childhood experiences increased the likelihood of smoking by the age of 14, chronic smoking as adults, and the presence of smoking-related diseases. Thus, smoking, which is medically and socially viewed as a “problem” may, from the perspective of the user, represent an effective immediate solution that leads to chronic use. Decades later, when this “solution” manifests as emphysema, cardiovascular disease, or malignancy, time and the

tendency to ignore psychological issues in the manage- ment of organic disease make improbable any full understanding of the original causes of adult disease (Figure 2). Thus, incomplete understanding of the possible benefits of health risk behaviors leads them to be viewed as irrational and having solely negative consequences.

Because adverse childhood experiences are common and they have strong long-term associations with adult health risk behaviors, health status, and diseases, in- creased attention to primary, secondary, and tertiary prevention strategies is needed. These strategies in- clude prevention of the occurrence of adverse child- hood experiences, preventing the adoption of health risk behaviors as responses to adverse experiences during childhood and adolescence, and, finally, help- ing change the health risk behaviors and ameliorating the disease burden among adults whose health prob- lems may represent a long-term consequence of ad- verse childhood experiences.

Primary prevention of adverse childhood experi- ences has proven difficult54,55 and will ultimately re- quire societal changes that improve the quality of family and household environments during childhood. Recent research on the long-term benefit of early home visitation on reducing the prevalence of adverse childhood experi- ences is promising.56 In fact, preliminary data from the ACE Study provided the impetus for the Kaiser Health Plan to provide funding to participate at 4 locations (including San Diego County, California) in the Com- monwealth Fund’s “Healthy Steps” program. This pro- gram extends the traditional practice of pediatrics by adding one or more specialists in the developmental and psychosocial dimensions of both childhood and parent- hood. Through a series of office visits, home visits, and a telephone advice line for parents, these specialists develop close relationships between children and their families from birth to 3 years of age. This approach is consistent with the recommendation of the U.S. Advisory Board on Child Abuse and Neglect that a universal home visitation program for new parents be developed57,58 and provides an example of a family-based primary prevention effort that is being explored in a managed care setting. If these types of approaches can be replicated and implemented on a large scale, the long-term benefits may include, somewhat unexpectedly, substantial improvements in overall adult health.

Secondary prevention of the effects of adverse child- hood experiences will first require increased recogni- tion of their occurrence and second, an effective un-

derstanding of the behavioral coping devices that commonly are adopted to reduce the emotional impact of these experiences. The improbability of giving up an immediate “solution” in return for a nebulous long- term health benefit has thwarted many well-intended preventive efforts. Although articles in the general medical literature are alerting the medical community to the fact that childhood abuse is common,59 adoles- cent health care is often inadequate in terms of psycho- social assessment and anticipatory guidance.60 Clearly, comprehensive strategies are needed to identify and intervene with children and families who are at risk for these adverse experiences and their related out- comes.61 Such strategies should include increased com- munication between and among those involved in family practice, internal medicine, nursing, social work, pediatrics, emergency medicine, and preventive medi- cine and public health. Improved understanding is also needed of the effects of childhood exposure to domes- tic violence.19,62 Additionally, increased physician train- ing63 is needed to recognize and coordinate the man- agement of all persons affected by child abuse, domestic violence, and other forms of family adversity such as alcohol abuse or mental illness.

In the meantime, tertiary care of adults whose health problems are related to experiences such as childhood abuse5 will continue to be a difficult challenge. The relationship between childhood experiences and adult health status is likely to be overlooked in medical practice because the time delay between exposure

during childhood and recognition of health problems in adult medical practice is lengthy. Moreover, these childhood exposures include emotionally sensitive top- ics such as family alcoholism29,30 and sexual abuse.64

Many physicians may fear that discussions of sexual violence and other sensitive issues are too personal even for the doctor-patient relationship.65 For example, the American Medical Association recommends screen- ing of women for exposure to violence at every en- trance to the health system;66 however, such screening appears to be rare.67 By contrast, women who are asked about exposure to sexual violence say they consider such questions to be welcome and germane to routine medical care,68 which suggests that physicians’ fears about patient reactions are largely unfounded.

Clearly, further research and training are needed to help medical and public health practitioners under- stand how social, emotional, and medical problems are linked throughout the lifespan (Figure 2). Such re- search and training would provide physicians with the confidence and skills to inquire and respond to patients who acknowledge these types of childhood exposures. Increased awareness of the frequency and long-term consequences of adverse childhood experiences may also lead to improvements in health promotion and disease prevention programs. The magnitude of the difficulty of introducing the requisite changes into

medical and public health research, education, and practice can be offset only by the magnitude of the implications that these changes have for improving the health of the nation.
