Abstract
Individual differences in physical and psychological health trajectories were examined in 1,515 Normative Aging Study men. Mean age at baseline was 47.15 years (range = 28-80), and average follow up was 18.55 years (range = 8-25). Both linear and nonlinear growth curves were estimated with random-effects models and then clustered to identify patterns of change. Men whose physical health trajectories were characterized by high, increasing symptoms were higher in hostility and anxiety, were overweight, and smoked. Those whose trajectories were characterized by low symptoms were emotionally stable, educated, nonsmokers, and thin. Men with high, stable psychological trajectories had high hostility; those with low, stable trajectories had high emotional stability; those with moderate anxiety levels had nonlinear trajectories with peaks in psychological symptoms at different life stages. Personality had life-long effects on health trajectories, but these effects varied across traits and health outcomes.

Abstract
The purpose of this study was to investigate cross-sectional and longitudinal associations between hearing acuity and tooth loss in 1156 US veterans taking part in the Veterans Affairs' Normative Aging (NAS) and Dental Longitudinal (DLS) Studies in the Boston, MA, area. The mean age was 48 years (SD = 8.9), 5.3% were edentulous, and 15.4% had < 17 teeth at baseline. Hearing acuity was determined by puretone, air- and bone-conduction audiometry, and speech discrimination tests at triennial examinations over a 20-year follow-up period. Hearing decline was defined as a change from baseline in the average puretone air-conduction thresholds of > or = 20 dB at 0.25, 0.5, 1, 2, 3, 4, 6, and 8 kHz. The explanatory variables of interest were change since baseline in dentate status (cut points at < 1, < 17, and < 20 teeth), and in the number of teeth lost (linear). Linear and logistic regression models--which controlled for baseline audiological status, age, air-bone gap, and otoscopic examination at current visit--showed that subjects who went from having > or = 17 to < 17 teeth had 1.64 times (95% CI, 1.24-2.17) as high odds of having hearing decline as those with no change in their dentate status. For every tooth lost since baseline, there was a 1.04 times as high odds (95% CI, 1.02-1.06) for hearing decline, when additional baseline and time-varying covariates were taken into account in the model.

Abstract
Is the recent construct of health-related quality of life (HQL) distinct from what gerontologists have long referred to as "well-being" or "life satisfaction?" We addressed this question using data from men in the VA Normative Aging Study to examine relations among twelve scales assessing HQL and seven scales of well-being (WB). We hypothesized that these two constructs would be distinct factorially, and that the derived factors would have different correlates. Correlations between scales of HQL and WB were moderate. When the nineteen scales were factored, four factors were extracted with HQL and WB scales generally loading on separate factors. The factors had distinct patterns of relations with general quality of life, personality, and the presence of a health problem, controlling for sociodemographics. These results suggest that HQL is distinct from the older construct of well-being. Although the two constructs are conceptually related, there is only a moderate amount of statistical overlap between them. Gerontologists should readily adopt health-related quality of life, which maintains continuity with such classics as well-being. This new construct, although needing slight alterations to broaden its assessment of well-being and life satisfaction, holds promise as more than an accessory in the study of health and well-being among older persons.

Abstract
Dispositional optimism has been linked in previous studies to better health outcomes. We sought to examine the independent associations of dispositional optimism and depressive symptoms with physical and mental functioning in a cohort of healthy middle-aged and older men. The study was conducted among 659 subjects in the Veterans Administration (VA) Normative Aging Study. Dispositional optimism and depressive symptomatology were measured in 1991 and 1990, respectively, by the Life Orientation Test and the Center for Epidemiologic Studies--Depression Scale (CES-D). The dependent variables, functioning and well-being, were measured in 1992 by the Medical Outcomes Study Short-Form Health Survey (SF-36). In multivariate regression models, optimism was associated with higher levels of general health perceptions, vitality, and mental health, and lower levels of bodily pain, but not to physical functioning, social functioning, or role limitations due to physical or emotional problems. Depressive symptomatology was associated with reduced levels of functioning across all SF-36 domains. The findings for optimism and depression were statistically significant after mutual adjustment in multivariate regression models. Optimism and depression are independent predictors of functional status among aging men.

Abstract
OBJECTIVES This project assessed the clinical oral health status of Veterans Administration (VA) patients and examined the relationship between oral health and both sociodemographic factors and dental care utilization. METHODS Data were collected on 538 users of VA ambulatory medical care. Oral health was assessed by clinical examinations, and dental use and sociodemographic information are based on self-report. RESULTS Younger, more educated VA patients with higher incomes had more teeth, fewer untreated and treated root caries, and were less likely to be edentulous or to have dentures. Dental utilization emerged as the most important aspect of veterans' oral health status, even after sociodemographic factors were controlled. Compared with the general population, veterans have poorer oral health with the exception of coronal caries. CONCLUSION Compared with national studies, VA patients appear to have worse oral health. The importance of sociodemographic factors and dental utilization that has been found in other studies applies to veterans' oral health as well.

Abstract
BACKGROUND This article describes the oral health of users of Veterans Administration (VA) health care using both clinical and self-report measures, and models relationships between these measures and self-perceived oral health. METHODS We conducted a cross-sectional study of 538 male users of VA outpatient care in the Boston area. Questionnaires assessed self-reported oral health, oral-specific health-related quality of life, health behaviors, and sociodemographic information. Clinical data were collected on oral mucosa status, number of teeth and root tips, dental caries, and periodontal treatment need. We report clinical and self-reported oral health status by age group (era of military service). We regressed models of self-perceived oral health on clinical indices and self-reported measures of the impact of oral health on daily life, adjusting for sociodemographic characteristics and health behavior. RESULTS Among those participants aged 65 to 91 years old, 2.8%, 18.7%, and 41.5% rated their oral health as excellent, very good, or good, respectively. Among 50- to 64-year-old men, the corresponding values were 1.4%, 18.5%, and 40.4%, while among those aged 22 to 49 years old, the values were 2.3%, 17%, and 34.1%. Tooth loss was common among users of VA care; 34% of those aged 65-90 years, 28% of those aged 50-64 years, and 8% of those aged 25-49 years had no teeth. Periodontal treatment needs were uniformly high among persons with teeth; mild mucosal change was common, and 10% had root tips. Regression models showed self-perceived oral health was better in persons with more teeth and recent dental treatment, and worse with tooth mobility, coronal decay, and more medical problems. Measures of the impact of oral conditions on daily life added significantly to the amount of explained variance in self-perceived oral health. CONCLUSIONS Clinical conditions and the impact of oral health on daily life are important determinants of self-perceived oral health.

Abstract
A new multiplexed, bead-based method which utilizes nucleic acid hybridizations on the surface of microscopic polystyrene spheres to identify specific sequences in heterogeneous mixtures of DNA sequences is described. The method consists of three elements: beads (5.6-microm diameter) with oligomer capture probes attached to the surface, three fluorophores for multiplexed detection, and flow cytometry instrumentation. Two fluorophores are impregnated within each bead in varying amounts to create different bead types, each associated with a unique probe. The third fluorophore is a reporter. Following capture of fluorescent cDNA sequences from environmental samples, the beads are analyzed by flow cytometric techniques which yield a signal intensity for each capture probe proportional to the amount of target sequences in the analyte. In this study, a direct hybrid capture assay was developed and evaluated with regard to sequence discrimination and quantitation of abundances. The target sequences (628 to 728 bp in length) were obtained from the 16S/23S intergenic spacer region of microorganisms collected from polluted groundwater at the nuclear waste site in Hanford, Wash. A fluorescence standard consisting of beads with a known number of fluorescent DNA molecules on the surface was developed, and the resolution, sensitivity, and lower detection limit for measuring abundances were determined. The results were compared with those of a DNA microarray using the same sequences. The bead method exhibited far superior sequence discrimination and possesses features which facilitate accurate quantitation.

Abstract
OBJECTIVES Although personality is known to influence patients' self-ratings of health, its effects on reports of health-related quality of life (HRQOL) have not been fully described. We examined the relationship between a dimension of personality called negative affectivity (NA; a general disposition to experience negative mood states) and HRQOL, controlling for age and common chronic physical and mental diseases. METHODS We used data from 3 samples of veterans: the Department of Veterans Affairs (VA) Normative Aging Study (NAS), the Veterans Health Study (VHS), and the VA Women's Health Project (VA WHP). For each of the 8 SF-36 scales and the physical and mental component summary scales, 2 regression models were estimated, the first of which included only chronic diseases and age and the second of which added NA. RESULTS NA was consistently negatively associated with SF-36 scale scores in bivariate analyses. The regression models indicated that across the 3 samples, NA explained between 0% and 13.9% additional variance in the scales, with the least additional variance in the physical function domains (range 0-2.6%) and the most in the mental function domains (range 0-13.9%). Results from the summary scales were similar: NA explained none of the variance in the physical component summary and 3.5% to 10.4% in the mental component summary. These results were largely consistent across the 3 samples. CONCLUSIONS These results suggest the importance of NA in patients' ratings of HRQOL beyond that of age and chronic conditions. Thus, clinicians and researchers who rely on measures such as the SF-36 to assess health status should consider that personality, as well as underlying health, can affect self-ratings of HRQOL.

Abstract
BACKGROUND We examined personality traits (Sociability, Impulsivity, Neuroticism) as mediators of the effects of family history on alcohol outcomes. METHODS A sample of 485 men reported on family history of alcohol problems in 1973, completed the Eysenck Personality Inventory in 1976, and responded to a survey on alcohol use in 1982. RESULTS Using structural equation modeling, family history was found to have direct effects on number of drinks per day and on the number of alcohol problems, as well as indirect effects mediated through Neuroticism. There were no effects of Sociability or Impulsivity on either alcohol outcome. CONCLUSIONS In this sample of older men, family history had both direct and indirect effects, and personality traits found to affect alcohol outcomes were different from those that have been found in younger men.

Abstract
OBJECTIVE Several studies have shown that hostility, as measured by the Minnesota Multiphasic Personality Inventory-derived Cook-Medley Hostility Scale (Ho), is positively associated with several cardiovascular risk factors, possibly accounting for the relationship between Ho scores and cardiovascular mortality. This study was undertaken to examine associations between hostility and cardiovascular risk factors representing the metabolic syndrome in 1,081 older men who participated in the Normative Aging Study. METHODS Subjects included men who completed the Minnesota Multiphasic Personality Inventory in 1986 and who participated in a subsequent laboratory examination within 1 to 4 years. Total and subscale Ho scores were computed, and associations with anthropometric data, cigarette smoking, dietary information, serum lipids, blood pressure, and fasting glucose and insulin levels were examined. RESULTS The total Ho score was positively associated with waist/hip ratio, body mass index, total caloric intake, fasting insulin level, and serum triglycerides. The Ho score was inversely related to education and high-density lipoprotein cholesterol concentration. Path analysis also suggested that the effects of hostility on insulin, triglycerides, and high-density lipoprotein cholesterol were mediated by its effects on body mass index and waist/hip ratio, which, in turn, exerted their effects on lipids and blood pressure through insulin. CONCLUSIONS The results are consistent with those of prior research and also suggest that, in older men, hostility may be associated with a pattern of obesity, central adiposity, and insulin resistance, which can exert effects on blood pressure and serum lipids. Furthermore, effects of hostility on the metabolic syndrome appear to be mediated by body mass index and waist/hip ratio.

Abstract
The association between physician-diagnosed medical disorders and combat-related posttraumatic stress disorder (PTSD) symptoms was examined in 605 male combat veterans of World War II and the Korean conflict. Physician exams were performed at periodic intervals beginning in the 1960s. PTSD symptoms were assessed in 1990. Cox regression was used to examine the onset of each of 12 disorder categories as a function of PTSD symptoms, controlling for age, smoking, alcohol use, and body weight at study entry. Even with control for these factors, PTSD symptoms were associated with increased onset of arterial, lower gastrointestinal, dermatologic, and musculoskeletal disorders. There was only weak evidence that PTSD mediated the effects of combat exposure on morbidity. Possible mediators of the relationship between combat exposure, PTSD, and physical morbidity are discussed.

Abstract
OBJECTIVE The authors examined the self-reported presence and treatment of current depressive disorder, posttraumatic stress disorder (PTSD), and alcohol-related disorder in a group of outpatient veterans. METHOD Data were obtained from the Veterans Health Study, a longitudinal investigation of male veterans' health. A representative sample of 2,160 outpatients (mean age = 62 years) was drawn from Boston-area U.S. Department of Veterans Affairs (VA) outpatient facilities. The participants completed screening measures for depression, PTSD, and alcohol-related disorder. Mental health treatment was assessed by interviews. RESULTS The screening criteria for at least one current mental disorder were satisfied by 40% (N = 856) of the patients. Screening rates were 31% (N = 676) for depression, 20% (N = 426) for PTSD, and 12% (N = 264) for alcohol-related disorder. Patients who screened positively for current mental disorders were younger, less likely to be married or employed, and more likely to report traumatic exposure than were those without mental disorders. Of those who met the screening criteria for any of the targeted mental disorders, 68% (N = 579) reported receiving mental health treatment. Younger, Caucasian men and those who reported more traumatic exposure were more likely to report receiving mental health treatment than were others who screened positively for mental disorders. CONCLUSIONS Screening rates of depression and PTSD and rates of mental health treatment were considerably higher among these VA outpatients than among similar patients in primary care in the private sector. Although the VA is currently meeting the mental health care needs of its patients, future fiscal constraints could affect most adversely the treatment of non-Caucasian and older patients and those with a history of traumatic exposure.

Abstract
We used path analysis to model the effects of combat exposure, posttraumatic stress disorder (PTSD) symptoms, and health behaviors on physical health. Participants were 921 male military veterans from the Normative Aging Study. Their mean age at time of study was 65. Measures of combat exposure, PTSD symptoms, smoking, and alcohol problems were used to predict subsequent self-reported physical health status. Both combat exposure and PTSD were correlated with poorer health. In path analysis, combat exposure had only an indirect effect on health status, through PTSD, whereas PTSD had a direct effect. Smoking had a small effect on health status but did not mediate the effects of PTSD, and alcohol was unrelated to health status. We conclude that PTSD is an important predictor of physical health and encourage further investigation of health behaviors and other possible mediators of this relationship.

Abstract
While prevention practices are widely encouraged, the link between the performance of preventive behaviors and oral health status has rarely been examined. This study investigates the association between preventive dental behaviors (recent and long-term) and oral health status and compares the strength of such associations. Longitudinal data over six time points on 649 dentate white men were obtained from the VA Dental Longitudinal Study (DLS). Participants' oral health was measured through dental examinations, and preventive dental behaviors--i.e., toothbrushing, flossing, using interdental devices, seeking dental prophylaxis, and undergoing dental treatment-were assessed by self-report. Oral health status was measured in terms of (1) functioning teeth, (2) sound-equivalent teeth, (3) decayed, missing, and filled teeth, and (4) decayed and filled root surfaces. Pearson correlation and linear regression analysis revealed significant positive associations between most preventive behaviors and measures of oral health status. Dental prophylaxis emerged as the strongest predictor of oral health status. Long-term preventive dental behavior measures explained more variance in oral health status than short-term preventive behaviors measured cross-sectionally.

Abstract
OBJECTIVE We examined whether alcohol consumption and problem drinking decreased with age or if the reported declines were actually cohort and/or period effects. METHOD We utilized data from the Normative Aging Study, assessing 1,267 men three times over an 18-year period (1973, 1982, 1991). Men were divided into five 9-year birth cohorts; age ranged from 46 to 72. RESULTS Sequential analyses using repeated measures ANOVAs showed significant age, cohort and period effects. Although there was a tendency for alcohol consumption to decline with age, this was not true for all cohorts. Men born between 1910 and 1918 increased from an average of 350 to 440 drinks per year from their fifties to their sixties. The younger cohorts tended to report both more consumption and more problems. However, period had the most consistent effect in this study. There was an increase in problems and in consumption during the 1970s but a decrease in the 1980s, with the exception of the youngest cohort (1937-1945) who reported more problems in the 1991 assessment despite lower consumption. CONCLUSIONS Age-related change in both consumption and problems varied depending upon which cohort or time period was assessed. Thus, drinking patterns are a complex amalgam of individual aging and societal change.

Abstract
This study modeled physical symptom trajectories from ages 30 to 75 in 1079 older male military veterans who were assessed every 3 to 5 years since the 1960s. Combat exposure and noncombat trauma were used to define four groups: no trauma (N = 249), noncombat trauma only (N = 333), combat only (N = 152), and both combat and noncombat trauma (N = 345). Number of symptoms on the Cornell Medical Index physical symptom scale increased 29% per decade. Men who had experienced either combat or noncombat trauma did not differ from nonexposed men, but those who had experienced both combat and noncombat trauma had 16% more symptoms across all ages. There were no differences in age-related trajectories as a function of trauma history. In cross-sectional analysis, men with combat and noncombat trauma had more posttraumatic stress disorder symptoms, but not more depression symptoms, than men with either no trauma or noncombat trauma only. Discussion focuses on the importance of considering physical as well as psychological outcomes of exposure to traumatic events.

Abstract
An evaluation is made of Goldberg s (1992) 100 Unipolar Markers of the five-factor model of personality. The factor structure of these items in samples of older men from the Normative Aging Study and undergraduate students are examined, and both item transformation and consistency testing approaches are used to evaluate replications of the five-factor structure. Results show that the five-factor structure is difficult to replicate in the sample of older men. While item transformations and sample trimming based on a consistency test did improve the quality of the replication in this older, nonstudent sample, both methods have serious drawbacks. The five-factor solution appeared in the student sample without sample trimming or data transformation. Additionally, in both student and nonstudent samples, oblique rotation resulted in inter-factor correlations relevant to more general issues in the study of trait structure. We conclude that the 100 Unipolar Markers may be unsuitable for use in older populations or with nonstudent samples.

Abstract
BACKGROUND Our objective was to develop a patient-based measure of the severity of osteoarthritis of the knee, focusing on symptomatology, that may be used in conjunction with measures of health-related quality of life in monitoring the health status of outpatients. METHODS We surveyed a random sample of male outpatients at Boston-area Veterans Affairs medical centers who were identified as having osteoarthritis of the knee according to a three-question screen. Structured interviews included 12 items covering five domains of symptoms (global severity, 4 items; pain with activity, 3 items; pain at rest, 2 items; impaired mobility, 2 items; and sensations of crepitus, 1 item), which were derived from clinical texts, consensus statements, and previously developed severity indices. Interviews also included a detailed medical history. Health-related quality of life was measured by the Medical Outcomes Study Health Status Survey (SF-36). Factor analysis and evaluation of multiattribute scales were used to evaluate the structural relationships between and within the five domains of symptoms. RESULTS We identified 415 of the 1770 screened outpatients as having osteoarthritis of the knee. Internal consistencies of the five domains ranged from .50 to .72, with substantial convergence between domains. The 12 items comprise a summary index with high internal consistency (alpha = .88). Overall severity, defined as the mean of the 12 items after standardization, was moderately correlated with the SF-36 component summaries: r = -.48 for physical; r = -.30 for mental. CONCLUSIONS Our measure provides a reliable index that represents symptomatic severity of osteoarthritis of the knee, which may be useful in comparing patient groups and assessing health outcomes; subscales may help characterize temporal changes, including responses to treatment.

Abstract
BACKGROUND Several methods exist by which to assess type A behavior (TAB). Although the videotaped clinical interview is regarded as the "gold standard," self-report measures have also proved useful in assessing TAB in large population studies. The purpose of this study was to examine prospectively the relationship of TAB to risk of coronary heart disease (CHD) incidence with the use of the revised Minnesota Multiphasic Personality Inventory (MMPI-2) Type A Scale. To the best of our knowledge, this is the first test of this scale in the context of predicting CHD incidence. METHODS AND RESULTS The study was performed in the VA Normative Aging Study, an ongoing cohort of older (mean age, 61 years) community-dwelling men. A total of 1305 men who were free of diagnosed CHD in 1986 completed the MMPI-2 Type A Scale. During an average 7.0 years of follow-up, 110 cases of incident CHD occurred. Compared with men in the lowest quartile of type A scores, men in the highest quartile had multivariate adjusted relative risks of 2.86 (95% CI, 1.19 to 6.89; P for trend=0.016) for combined CHD death and nonfatal myocardial infarction (MI) and 2.30 (95% CI, 1.32 to 4.01; P for trend=0.001) for combined CHD death/nonfatal MI plus angina pectoris. The relationship of TAB to CHD was independent of measures of anger and cynicism. CONCLUSIONS The MMPI-2 Type A Scale predicts CHD incidence. Further research is warranted to examine the correlation, if any, between this scale and the videotaped clinical interview.

Abstract
BACKGROUND The Department of Veterans Affairs Health Care System (VA) is the largest integrated single payer system in the United States. To date, there has been no systematic measurement of health status in the VA. The Veterans Health Study has developed methods to assess patient-based health status in ambulatory populations. OBJECTIVES To describe the health status of veterans and examine the relationships between their health-related quality of life, age, comorbidity, and socioeconomic and service-connected disability status. METHODS Participants in the Veterans Health Study, a 2-year longitudinal study, were recruited from a representative sample of patients receiving ambulatory care at 4 VA facilities in the New England region. The Veterans Health Study patients received questionnaires of health status, including the Medical Outcomes Study Short Form 36-Item Health Survey; and a health examination, clinical assessments, and medical history taking. Sixteen hundred sixty-seven patients for whom we conducted baseline assessments are described. RESULTS The VA outpatients had poor health status scores across all measures of the Medical Outcomes Study Short Form 36-Item Health Survey compared with scores in non-VA populations (at least 50% of 1 SD worse). Striking differences also were found with the sample stratified by age group (20-49 years, 50-64 years, and 65-90 years). For 7 of the 8 scales (role limitations due to physical problems, bodily pain, general health perceptions, vitality, social functioning, role limitations due to emotional problems, and mental health), scores were considerably lower among the younger patients; for the eighth scale (physical function), scores of the young veterans (aged 20-49 years) were almost comparable with the levels in the old veterans (>65 years). The mental health scores of young veterans were substantially worse than all other age groups (P<.001) and scores of screening measures for depression were significantly higher in the youngest age group (51%) compared with the oldest age groups (33% and 16%) (P<.001). CONCLUSIONS The VA outpatients have substantially worse health status than non-VA populations. Mental health differences between the young and old veterans who use the VA health care system are sharply contrasting; the young veterans are sicker, suggesting substantially higher resource needs. Mental health differences may explain much of the worse health-related quality of life in young veterans. As health care systems continue to undergo a radical transformation, the Department of Veterans Affairs should focus on the provision of mental health services for its younger veteran.

Abstract
OBJECTIVE Little is known about the significance of patient-perceived overmedication. We sought to determine its prevalence and relation to medication compliance, adverse drug reactions, health-related quality of life (HRQOL), and burden of illness. DESIGN Analysis of self-reported questionnaire data. PATIENTS/PARTICIPANT: There were 1,648 participants in a longitudinal study of male veterans. INTERVENTION Participants listed each of their medications with indication, missed doses, adverse reactions, and whether their amount of medication was "too much, the right amount, or too little." The survey included questions about medication adherence, "problems with medications," common symptoms, and screening questions for a number of chronic conditions. We assessed HRQOL with the Multiple Outcomes Study 36-Item Short Form Health Study (SF-36). MEASUREMENTS AND MAIN RESULTS Of the 1,256 respondents, 1,007 (80%) had taken medication within 4 weeks. Forty (4%) thought they were taking too much. They reported a 1.6-fold increase in prescription medications, a 5-8 fold increase in adverse effects, a 1.5-2 fold decrease in compliance, an increase in each of seven measured symptoms, and a decrease in six of eight SF-36 domains (p < .05 for all comparisons), the exceptions being the mental health and role-emotional scales. There was also a slight increase in the report of any chronic illness (95% vs 86%, p > .05). CONCLUSIONS Patient perception of overmedication correlates with self-report of decreased compliance, adverse drug reactions, decreased HRQOL, and an increase in symptomatology that is compatible with unrecognized side effects of medication. Such patients warrant careful evaluation.

Abstract
The relationship between performance on cognitive tasks and circulating levels of lead in blood and accumulated levels of lead in bone was examined in 141 middle-aged and elderly men from a longitudinal study of aging. The mean (SD) blood lead level was low [5.5 (3.5) micrograms/dl], and mean patella and tibia lead levels were 31.7 (19.2) and 22.5 (12.2) micrograms/g bone mineral, respectively. Cognitive tests measured attention, perceptual speed, memory, language, and spatial copying. Regression models, adjusted for age and education, demonstrated that men with higher levels of blood lead recalled and defined fewer words, identified fewer line-drawn objects, and required more time to attain the same level of accuracy on a perceptual comparison test as men with the lowest level of blood lead. Men with higher levels of blood and bone (tibia) lead copied spatial figures less accurately; men with higher levels of bone (tibia) lead had slower responses for pattern memory. These findings suggest that low levels of lead contribute to impairments in cognitive function among elderly men.

Abstract
BACKGROUND Worry is an important component of anxiety, which recent work suggests is related to increased incidence of coronary heart disease (CHD). Chronic worry has also been associated with decreased heart rate variability. We hypothesized that high levels of worry may increase CHD risk. METHOD AND RESULTS We examined prospectively the relationship of worry with CHD incidence in the Normative Aging Study, an ongoing cohort of older men. In 1975, 1759 men free of diagnosed CHD completed a Worries Scale, indicating the extent to which they worried about each of five worry domains: social conditions, health, financial, self-definition, and aging. During 20 years of follow-up, 323 cases of incident CHD occurred: 113 cases of nonfatal myocardial infarction (MI); 86 cases of fatal CHD; and 124 cases of angina pectoris. Worry about social conditions was the domain most strongly associated with incident CHD. Compared with men reporting the lowest levels of social conditions worry, men reporting the highest levels had multivariate adjusted relative risks of 2.41 (95% CI, 1.40 to 4.13) for nonfatal MI and 1.48 (95% CI, 0.99 to 2.20) for total CHD (nonfatal MI and fatal CHD). A dose-response relation was found between level of worry and both nonfatal MI (P for trend, .002) and total CHD (P for trend, .04). CONCLUSIONS These results suggest that high levels of worry in specific domains may increase the risk of CHD in older men.

Abstract
BACKGROUND Recent laboratory and epidemiological studies have suggested that high levels of anger may increase the risk of coronary heart disease (CHD). METHODS AND RESULTS We examined prospectively the relationship of anger to CHD incidence in the Veterans Administration Normative Aging Study, an ongoing cohort of older (mean age, 61 years) community-dwelling men. A total of 1305 men who were free of diagnosed CHD completed the revised Minnesota Multiphasic Personality Inventory (MMPI-2) in 1986. Subjects were categorized according to their responses to the MMPI-2 Anger Content Scale, which measures the degree to which individuals have problems controlling their anger. During an average of 7 years of follow-up, 110 cases of incident CHD occurred, including 30 cases of nonfatal myocardial infarction hostility. (MI), 20 cases of fatal CHD, and 60 cases of angina pectoris. Compared with men reporting the lowest levels of anger, the multivariate-adjusted relative risks among men reporting the highest levels of anger were 3.15 (95% confidence interval) [CI]: 0.94 to 10.5) for total CHD (nonfatal MI plus fatal CHD) and 2.66 (95% CI: 1.26 to 5.61) for combined incident coronary events including angina pectoris. A dose-response relation was found between level of anger and overall CHD risk (P for trend, .008). CONCLUSIONS These data suggest that high levels of expressed anger may be a risk factor for CHD among older men.
