Serum iron level, coronary artery disease, and all-cause mortality in older men and women.

The association between iron levels and coronary artery disease (CAD) mortality is controversial. Whereas most data show no association, some have raised the possibility of a causal role, while others have suggested a protective effect of iron on CAD. To address these possibilities, we examined the association between serum iron and CAD, cardiovascular disease, and all-cause mortality in a large cohort of 3,936 persons aged > or =71 years who completed an interview, had a serum iron determination, and survived at least 1 year after baseline. The median follow-up time was 4.4 years. Serum iron levels were categorized according to sex-specific quartiles. Relative risks (RR) and 95% confidence intervals (CI) were calculated from proportional-hazards regression models adjusted for age, race, education, creatinine, serum albumin, serum lipids, use of iron supplementation, smoking, use of alcohol, blood pressure, body mass index, and presence of chronic conditions. There was a gradual decrease in the RRs of CAD, cardiovascular disease, and all-cause mortality with increasing serum iron levels (all tests for trend, p <0.05). Men in the highest iron quartile were one fifth as likely to die of CAD as men in the lowest iron quartile (RR 0.22; 95% CI 0.11 to 0.48), and women in the highest quartile had half the risk of women in the lowest quartile (RR 0.48; 95% CI 0.27 to 0.87). When compared with the lowest quartile, risk of all-cause mortality was 38% lower in men in the highest iron quartile (RR 0.62; 95% CI 0.46 to 0.85) and 28% lower in women in the highest quartile (RR 0.72; 95% CI 0.53 to 0.96). Results of similar strength and magnitude were observed for cardiovascular disease mortality and in analyses that excluded the first 3 years of follow-up. In this large cohort of persons aged > or =71 years, there was consistent evidence of increasing risk of mortality at lower serum iron levels. In fact, lower serum iron levels were associated with an increased risk of CAD, cardiovascular disease, and all-cause mortality. The results are compatible with the possibility that in an older population, there is an inverse association between serum iron levels and risk of mortality.

Serum albumin and physical function as predictors of coronary heart disease mortality and incidence in older persons.

The role of traditional risk factors in predicting coronary heart disease (CHD) among men and women aged 65 years and over has been extensively debated, but the search for risk factors that are distinctive in the elderly is still ongoing. The relation of serum albumin levels and physical disability to risk of CHD morality and incidence was prospectively assessed in a cohort of 4116 men and women, aged 71 years and over, who were evaluated in 1987-1989 and followed for a mean of 4.0 years. Outcome events were based on death certificates and Medicare hospitalization records. Analyses were adjusted for major CHD risk factors. There were 275 CHD deaths (16.8/1000 person-years) among all participants and 503 incident (fatal and nonfatal) CHD events (39.4 per 1000 person-years) among participants free of prevalent CHD during the observation period. The relative risk (RR) of CHD morality for women with an albumin concentration < 38 g/liter was 2.5 times higher than for women with albumin > 43 g/liter (RR 2.5; 95% confidence interval [CI], 1.4-4.6). There was a significant and graded increase in CHD incidence with decreasing albumin concentration in women but not in men. The presence of physical disability doubled the risk of CHD mortality among both men and women, an increase in risk that was comparable to that imposed by a previous myocardial infarction and was independent of other coronary risk factors. Disability had a lesser impact on CHD incidence, which was significant only in women. Low albumin concentration (< 38 g/liter) identifies a group of women at higher risk of CHD mortality and incidence. Physical disability is an independent predictor of CHD mortality in both men and women and for CHD incidence only in women.

Antidepressant use in the elderly: association with demographic characteristics, health-related factors, and health care utilization.

The characteristics of antidepressant use and its correlates were assessed in the four Established Populations for Epidemiologic Study of the Elderly (EPESE) communities (n = 13,074). Women were significantly more likely to be treated with an antidepressant drug than men, and African-Americans were significantly less likely than whites to be using antidepressant medication. Of the health-related measures, poor self-perceived health, polypharmacy, disabilities in activities of daily living, and a history of stroke were associated with the use of antidepressants. Each utilization of health care variable, (number of doctors visits, overnight hospitalization in the past year, and use of a regular doctor), was associated with antidepressant use in at least two of the four communities. After entering variables in a multivariate regression model, higher antidepressant use was significantly associated with female gender, race, poor self-perceived health, and a greater number of contacts with doctors in the past year.

Serum albumin in older persons: relationship with age and health status.

We analyzed data from 4115 persons aged 71 years and older who had blood drawn at a home visit in three communities to examine the cross-sectional distribution of serum albumin and correlates of hypoalbuminemia. Mean albumin was lower among older persons, from 41.6 g/l in men aged 71-74 years to 38.5 g/l in men 90 years or older, and from 41.1 g/l to 38.9 g/l in women of the same ages, respectively. Hypoalbuminemia (albumin less than 35 g/l) was observed in 3.1% of subjects. Hypoalbuminemia and lower serum albumin were independently associated with anemia, recent diagnosis of cancer, two or more limitations in activities of daily living, residence in a nursing home, heavy cigarette smoking (greater than 1 pack/day), and older age. A 10-year age increment was associated with 0.8 g/l lower serum albumin and odds ratio of 1.56 (95% CI 1.14, 2.13) for hypoalbuminemia after adjusting for demographic factors and health status. Characteristics associated with serum albumin may confound the reported relationship between serum albumin and mortality.

Effect of age and severity of disability on short-term variation in walking speed: the Women's Health and Aging Study.

Standardized objective measures of human performance have been introduced in clinical and epidemiologic studies of older populations. Reliability of these measures has usually been estimated by comparing two measures obtained in the same person. However, no information is available on variability of multiple measures collected serially over short time intervals. This study uses data from the Weekly Disability Study, a component of the Women's Health and Aging Study, to describe fluctuations in physical performance over multiple, consecutive time intervals. Walking speed was measured weekly over a 6-month period in 99 older women affected by mild to severe disability. Overall, 2120 observations were explored using techniques developed for the analysis of repeated measures. Results showed that the correlations between observations in the same person were inversely related to their separation in time. The decay in the autocorrelation function was steeper in the least disabled. However, even with 20-week separations in assessments, correlations remained above 0.6 in all age and severity of disability subgroups. Changes over time in performance differed somewhat between disability subgroups, but the relative performance across subgroups remained stable over the entire course of the study. A clear learning effect was found only in those in the middle disability subgroup. Results support the utilization of repeated measures of physical performance in research that evaluates older persons over time.

Stevens-Johnson syndrome and toxic epidermal necrolysis after vaccination: reports to the vaccine adverse event reporting system.

We conducted a telephone survey of reports of Stevens-Johnson syndrome (SJS) and toxic epidermal necrolysis (TEN) to the Vaccine Adverse Event Reporting System. We identified six cases of SJS or TEN after vaccination without other obvious triggers, suggesting that SJS and TEN might very rarely be caused by vaccination. Confirmation of this hypothesis will likely require controlled studies.

Depression and smoking cessation in older adults: a longitudinal study.

OBJECTIVE: To explore the relationship of smoking cessation and depression. DESIGN: Cohort study with 3 years of follow-up. SETTING: North Carolina community of the Established Populations for the Epidemiologic Studies of the Elderly. PARTICIPANTS: Stratified cluster sample of adults age 65 years and older, with an oversampling of African Americans. MAIN MEASURES: Depressive symptoms using a modified Center for Epidemiologic Studies Depression (CES-D) scale; smoking cessation using change in self-reported smoking. RESULTS: Current smokers had the highest prevalence of clinically significant CES-D scores (11.2%), followed by never smokers (9.6%) and former smokers (7.1%). After 3 years, 128 (25%) of 511 baseline current smokers had quit. Among women with a clinically significant CES-D score, 55% quit smoking, compared with only 25% among those with a normal score (P < 0.05). Depressive symptoms were significantly associated with nearly fourfold increased odds of smoking cessation among women (relative odds [RO] 3.7, 95% confidence interval [CI] 1.2, 11.0; P < 0.05), but not among men (RO 0.6, 95% CI 0.2, 2.0, not significant), after adjusting for potential confounding. CONCLUSIONS: Depressive symptoms may directly increase the likelihood of smoking cessation among older women. When predicting smoking cessation, depression and gender should be considered in combination since to consider them separately may be misleading. This challenges prior reports that depressed smokers are less likely to quit smoking than nondepressed smokers.

Disability and severe gastrointestinal hemorrhage. A prospective study of community-dwelling older persons.

OBJECTIVE: To describe the occurrence of severe gastrointestinal bleeding in community-dwelling older persons and to examine whether disability is a risk factor for this life-threatening condition independent of other known predictors. DESIGN: Prospective cohort survey. SETTING: Three communities of the Established Populations for Epidemiologic Studies of the Elderly (EPESE). PARTICIPANTS: 8205 persons age > or = 68 years. MEASUREMENTS: The hospital discharge diagnoses provided by the Medicare Provider Analysis and Review files and the death certificates were prospectively surveyed for 3 years. Those with at least 1 discharge diagnosis of gastrointestinal bleeding and who received a blood transfusion or died were identified as cases of severe gastrointestinal hemorrhage. Physical disability, cognitive function, smoking and alcohol intake habits, body mass index, blood pressure, chronic conditions, number of hospital admissions in past year and medications taken were assessed at baseline. RESULTS: The occurrence rate of severe gastrointestinal bleeding was 10.8 per 1000 person-years (241 events/22,277 person-years). In proportional hazards regression models, compared with no disability, > or = 1 disabilities in the Rosow-Breslau scale (RR = 2.1, 95% CI = 1.5-2.9), and > or = 1 ADLs limitations (RR = 3.1, 95% CI = 2.1-4.6) independently predicted gastrointestinal hemorrhage after adjusting for age, gender, body mass index, comorbidity, number of hospital admissions, blood pressure, intake of coumarin, corticosteroids, aspirin and other nonsteroidal anti-inflammatory drugs. CONCLUSIONS: In this prospective analysis, disability is an independent predictor of gastrointestinal hemorrhage. Further studies are needed to explain the mechanisms by which disability may cause gastrointestinal hemorrhage. Because physical disability is potentially modifiable, strategies to lower the risk of gastrointestinal bleeding should be evaluated.

Association of visual impairment with mobility and physical function.

OBJECTIVE: To examine the association of distant vision and physical function in the population of older adults. DESIGN: Cross-sectional and cohort study. PARTICIPANTS: 5143 older residents of three communities (Established Populations for the Epidemiologic Studies of the Elderly) who were interviewed in 1988-89, including residents of two communities who were re-interviewed 15 months later (n = 3133, 97% of those eligible). MEASURES: Visual acuity screening, self-reported activities of daily living and mobility, and objective physical performance measures of balance, walking, and rising from a chair. RESULTS: Limitations in mobility, activities of daily living, and physical performance were associated with worse visual function. In prospective analyses controlling for potential confounders, participants with severe visual impairment had 3-fold higher odds of incident mobility and activity of daily living limitations than those with acuity of 20/40 or better (P < 0.001). In prospective analyses investigating the relationship of vision with improvement in function, those with poor vision were about half as likely to improve as those with better acuity, but this relationship was only statistically significant for improvement in mobility limitations. CONCLUSIONS: Distant visual function appears to play an important role in physical function, particularly for mobility. An intervention to improve vision in at-risk elders might preserve function and prevent disability; this warrants further investigation.

Occult caffeine as a source of sleep problems in an older population.

OBJECTIVE: To evaluate the impact of caffeine in medication on sleep complaints in a community population of persons aged 67 or older. DESIGN: Cross-sectional analysis. SETTING: Iowa 65+ Rural Health Study. PARTICIPANTS: Those who completed their own interview, including a section on the use of medications, during the third annual in-person follow-up in 1984-1985. MAIN OUTCOMES: trouble falling asleep or other sleep complaints. Covariates: use of caffeine-containing medication, spasmolytic, or sympathomimetic drug; number of drugs used; depressive symptoms; self-perceived health; comorbidity, hip fracture, arthritis, ulcer of stomach or intestines; and consumption of caffeinated beverages. RESULTS: The prevalence of caffeinated medication use by participants was 5.4%. Those reporting the use of any caffeine-containing medication were at an increased risk of having trouble falling asleep (Odds Ratio [OR] = 1.79, 95% confidence interval [CI] = 1.19-2.68). There was no significant risk of other reported nighttime or daytime sleep problems associated with use of caffeine-containing drugs. Even after adjusting for other factors that could interfere with initiation of sleep, such as painful disease, depressive symptoms, polypharmacy, use of specific medications known to interfere with sleep, and coffee consumption, the use of caffeine-containing medication still presented a significantly increased risk of having trouble falling asleep (OR = 1.60, CI = 1.04-2.46). Although those participants using over-the-counter analgesic medication containing caffeine had an increased risk of trouble falling asleep (OR = 1.88, CI = 1.22-2.90), there was no significant risk of trouble falling asleep for those who took similar noncaffeinated OTC analgesic drugs (OR = 1.26, CI = 0.87-1.83). CONCLUSIONS: The use of caffeine-containing medication is associated with sleep problems. Healthcare providers should be aware of potential problems associated with over-the-counter medications containing caffeine and should counsel patients about the potential of sleep problems. Older patients should be encouraged to read the label on medications and to select drugs that are caffeine-free when that is possible.

Anemia and hemoglobin levels in older persons: relationship with age, gender, and health status.

OBJECTIVE: To determine the relationship of hemoglobin levels and anemia with age and health status in older adults. DESIGN: Survey. SETTING: Community. PARTICIPANTS AND METHODS: Hematologic tests were obtained from 3,946 adults aged greater than or equal to 71 years in three communities (East Boston, MA; Iowa and Washington counties, IA; and New Haven, CT). RESULTS: Hemoglobin level was inversely associated with age, although this was more pronounced in men than in women. The proportion anemic was equal for men and women aged 71-74 years (8.6%) and increased differentially with age, reaching 41% and 21% for men and women aged greater than or equal to 90 years, respectively. Hemoglobin and anemia were independently associated with age, race, body-mass index, smoking, cancer, hospitalization, renal insufficiency, and hypoalbuminemia. The adjusted relative odds of anemia for a 5-year increase in age was 1.5 (95% confidence interval [CI] 1.3-1.8) for men and 1.2 (95% CI 1.1-1.4) for women. CONCLUSIONS: Age is significantly associated with both hemoglobin levels and anemia, with a stronger effect in men compared with women, even after simultaneously adjusting for demographic characteristics and health status. The decline of hemoglobin and concomitant increased anemia with age is not necessarily a result of "normal aging" so the detection of anemia in an older person should prompt appropriate clinical attention.

Alcohol consumption and risk of deep venous thrombosis and pulmonary embolism in older persons.

OBJECTIVES: To assess whether low to moderate alcohol consumption decreases the risk of deep venous thrombosis and pulmonary embolism. DESIGN: Prospective cohort study. SETTING: Three communities of the Established Populations for Epidemiologic Studies of the Elderly. PARTICIPANTS: A total of 7959 persons aged 68 years or older. MEASUREMENTS: The incidence of deep venous thrombosis and pulmonary embolism was assessed by surveying hospital discharge diagnoses and deaths from 1985 through 1992. Those participants who estimated they used alcohol less than 1 time, on average, in the past month, less than 1 ounce per day, and 1 ounce or more per day were compared with those who reported no alcohol intake in the past year. Age, gender, race, body mass index, smoking, education, income, disability, cognitive function, arterial pressure, medication use, baseline chronic conditions, number of hospital admissions in past year, and occurrence of disease during follow-up were examined as possible confounders. RESULTS: During 48,038 person-years of follow-up, 155 events were observed (35 deep venous thromboses and 123 pulmonary emboli). Compared with non-drinkers, after adjusting for potential confounding variables, the relative risks (95% confidence interval) for deep venous thrombosis and pulmonary embolism associated with increasing alcohol consumption levels were 0.7 (0.4-1.1), 0.6 (0.4-0.9), and 0.5 (0.2-1.1), respectively (P for trend = .004). The results were unchanged after stratifying on health status and disability. CONCLUSIONS: Low to moderate alcohol consumption is associated with a decreased risk of deep venous thrombosis and pulmonary embolism in older persons.

The renal effects of nonsteroidal anti-inflammatory drugs in older people: findings from the Established Populations for Epidemiologic Studies of the Elderly.

OBJECTIVE: To determine whether older people who use nonsteroidal anti-inflammatory agents (NSAIDs) have increased levels of blood urea nitrogen (BUN), serum creatinine, and BUN:serum creatinine ratio. DESIGN: Cross-sectional, secondary data analysis. SETTING: Older people living in the communities of East Boston, MA, New Haven, CT, and Washington and Iowa Counties, Iowa. PARTICIPANTS: A total of 4099 people aged 70 years or older who were participants in the National Institute on Aging's Established Populations for Epidemiologic Studies of the Elderly project, had survived to the 6-year follow-up interview and had consented to the blood drawing. MEASUREMENTS: We assessed use of the NSAIDs at the 3- and 6-year interviews through a drug inventory and visual review of medication containers. Markers of renal function assessed through analysis of blood samples drawn at the time of the interview included BUN and creatinine. RESULTS: Fifteen percent of the cohort reported use of NSAIDs during the 2 weeks preceding the 6-year interview. Controlling for age, sex, and a range of potential confounding variables, NSAID users had significant prevalence odds ratios of 1.9 (95% confidence interval (CI), 1.5-2.3) for being in the highest quartile of BUN (>23), 1.3 (CI 1.1-1.7) for the highest quartile of serum creatinine (> or =1.4), and 1.7 (CI 1.4-2.1) for the highest quartile of the BUN:creatinine ratio (> or = 19.4). Chronic NSAID users (those who reported NSAID use at both the 3-year and 6-year interviews) accounted for the increased risk of high serum creatinine levels. CONCLUSION: Community-dwelling older people who use NSAIDs tend to have higher levels of common laboratory markers of renal dysfunction. This hypothesis requires further testing in prospective cohort studies designed a priori to evaluate these issues.

Cognitive impairment and risk of stroke in the older population.

OBJECTIVE: Recent studies have suggested that vascular dementia in older persons is more common than previously hypothesized. A substantial proportion of dementia in old age may be an early manifestation of cerebrovascular disease (CVD), that eventually becomes clinically evident as an acute cerebrovascular accident. This study was aimed at assessing whether cognitive impairment and cognitive decline in older persons free of stroke are associated with higher risk of future stroke, independently of other risk factors. DESIGN: Population-based prospective study. PARTICIPANTS: A total of 5024 subjects from the Established Populations for Epidemiologic Studies of the Elderly, who were alive and had no history of previous stroke at the sixth follow-up visit. Subjects who had reported a stroke in a previous interview or with a diagnosis of cerebrovascular disease in a hospitalization record during the previous 3 years were excluded. MEASUREMENTS: Cognitive function was assessed by the Short Portable Mental Status Questionnaire (SPMSQ). Occurrence of a stroke was prospectively assessed by examining hospital discharge diagnoses and death certificates. RESULTS: During 19,533 person-years of follow-up, 259 strokes were recorded (13.3/1000 person-years). Stroke incidence was lowest in those with normal SPMSQ score (12.1/1000 person-years), intermediate in those with moderate impairment (16.3/1000 person-years), and highest in those with severe impairment (30.9/1000 person-years). Adjusting for age, education, smoking, history of hypertension, blood pressure, heart attack, diabetes, and disability, the relative risks of stroke for moderate and severe cognitive impairment were 1.2 (0.9-1.6) and 2.2 (1.2-3.8), respectively. The association between cognitive impairment and incident stroke was not mediated by hypertension or diabetes. Compared with subjects with stable or improved SPMSQ score in the previous 3 years, those who declined had higher risk of stroke. CONCLUSIONS: The elevated risk of subsequent strokes in older persons with cognitive impairment suggests that CVD may play larger role in causing cognitive impairment then previously suspected. It remains to be demonstrated whether reducing modifiable risk factors for CVD decreases the burden of cognitive impairment in older persons without stroke.

Do calcium channel blockers increase the risk of cancer?

Calcium channel blockers can block calcium signals that trigger cell differentiation and apoptosis, which are important mechanisms of cancer growth regulation. To ascertain whether calcium channel blocker use was associated with an increased risk of cancer, 750 hypertensive persons age > or = 71 years, with no history of cancer at baseline, were followed from 1988 through 1992. The patients were using either beta-blockers, angiotensin converting enzyme inhibitors or calcium channel blockers (verapamil, nifedipine, and diltiazem; mainly of the short-acting variety). Compared to beta-blockers (n = 424, 28 events), after adjusting for age, gender, race, smoking, body mass index, and number of hospital admissions not related with cancer, the relative risks of cancer (95% confidence interval) for angiotensin converting enzyme inhibitors (n = 124, 6 events) and calcium channel blockers (n = 202, 27 events) were 0.73 (0.30 to 1.78) and 2.02 (1.16 to 3.54), respectively. These findings indicate that calcium channel blocker therapy might increase the risk of cancer. New data are needed in patients using modern calcium channel blocker agents with more gradual absorption. This report should encourage further study of cancer outcomes in elderly patients who are vulnerable to cancer and who are receiving calcium channel blockers.

Progressive versus catastrophic disability: a longitudinal view of the disablement process.

BACKGROUND: There is little epidemiologic data on the development of disability over time in older persons. This study uses prospective data from cohorts followed annually for 6 to 7 years to identify persons who developed severe disability and to characterize the time course of their disabling process and subsequent mortality. METHODS: Incidence rates of severe disability, defined as need for help in three or more activities of daily living (ADLs), were estimated for 6,640 persons who had not reported severe disability at baseline and at the first four annual follow-up visits. Among persons developing severe disability, those who reported no need for help in ADLs in previous interviews were defined as cases of catastrophic disability, and those who had previously reported some disability in ADLs were defined as cases of progressive disability. RESULTS: Overall, 212 subjects developed progressive and 227 developed catastrophic disability. The rates of progressive disability and catastrophic disability were 11.3 and 12.1 cases per 1,000 person-years, respectively. For both types of disability, incidence rates increased exponentially with age, but the increase was steeper for progressive disability. At ages 70-74, less than 25% of severe disability was progressive, while over age 85 progressive disability represented more than half of severe disability. Incidence rates of total and both types of severe disability were similar in men and women. Mortality after severe disability onset was extremely high. Survival was unrelated to age at disability onset and type of disability but was significantly longer in women than in men (median 3.44 vs 2.12 years; p < .0001). CONCLUSION: Tracking the development of disability provides new and important insights into the disability experience in older men and women that are potentially relevant in planning preventive, intervention, and long-term care strategies.

Neonatal deaths after hepatitis B vaccine: the vaccine adverse event reporting system, 1991-1998.

OBJECTIVE: To evaluate reports of neonatal deaths (aged 0-28 days) after hepatitis B (HepB) immunization reported to the national Vaccine Adverse Event Reporting System (VAERS). DESIGN: Case series; review of autopsy reports. SETTING: Voluntary reports submitted to VAERS, a passive surveillance system, from the US population. PATIENTS: All US neonates (0-28 days of age) whose deaths after HepB vaccination given alone were reported to VAERS, occurring from January 1, 1991, through October 5, 1998. INTERVENTION: None (observational database). RESULTS: Of 1771 neonatal reports, there were 18 deaths in 8 boys and 9 girls (1 patient unclassified). The mean age at vaccination for these 18 cases was 12 days (range, 1-27 days); median time from vaccination to onset of symptoms was 2 days (range, 0-20 days); and median time from symptoms to death was 0 days (range, 0-15 days). The mean birth weight of the neonates (n = 15) was 3034 g (range, 1828-4678 g). The causes of death for the 17 autopsied cases were sudden infant death syndrome for 12, infection for 3, and 1 case each of intracerebral hemorrhage, accidental suffocation, and congenital heart disease. CONCLUSION: Few neonatal deaths following HepB vaccination have been reported, despite the use of at least 86 million doses of pediatric vaccine given in the United States since 1991. While the limitations of passive surveillance systems do not permit definitive inference, these data suggest that HepB immunization is not causing a clear increase in neonatal deaths.

The practice and earnings of preventive medicine physicians.

A shortage of preventive medicine (PM) physicians exists in the United States. Researchers know little about these physicians' earnings and practice characteristics. The American College of Preventive Medicine (ACPM) mailed a survey to all self-identified PM physicians on the American Medical Association (AMA) Physician Masterfile. A total of 3,771 (54%) responded; respondents' sex and region of residence were typical for PM physicians in general, with a slight excess of older physicians and those reporting board certification. A total of 2,664 (71%) were working full time, with median earnings of $85,000 (mean $90,000). Among full-time physicians, relatively higher earnings were associated with the following characteristics: male sex; age 45 to 64 years; major source of income from clinical, business, or industrial sources, rather than governmental or academic; and PM board certification. Full-time PM physicians earned much less than office-based private practitioners in several primary care specialties in 1989. The gap in earnings between PM specialists in government positions and those in the private sector is also substantial. Both disparities may require creative solutions.

Preventive medicine physician satisfaction and its relation to practice characteristics.

BACKGROUND: Physicians specializing in general preventive medicine and public health manage programs, conduct research, and care for patients. This study examines their satisfaction overall and in five dimensions: contribution to people's lives, respect from physicians in clinical practice, research opportunities, income, and time to pursue outside interests. METHODS: A survey of 1979-1989 graduates of preventive medicine residencies rated satisfaction on a five-point scale. Linear models were used to regress physician satisfaction against employer, hours worked, practice content, and other covariates. RESULTS: Respondents' (n = 778) overall job satisfaction was high, with 44% very satisfied, 44% satisfied, 7% neutral, and 6% dissatisfied. Federal government physicians had the highest satisfaction overall and for research opportunities and time for outside interests. Independent, statistically significant (p < .001) associations were found between higher satisfaction with research opportunities among academic and federal government employers, among Caucasians, and those with substantial epidemiologic practice; and lower satisfaction with time to pursue outside interests, more hours worked, and among women. CONCLUSIONS: Physician satisfaction could be understood in relation to a number of practice characteristics including its content, hours worked, income, and employer. The results suggest ways to improve physician satisfaction, including balancing competing demands of practice and focusing the physicians' responsibilities.

Preventive medicine residency training: a resident's perspective.

Preventive medicine as a discipline confronts considerable internal and external pressure today about society's needs for prevention specialists. Training in the field has remained static in the face of great changes. This article asserts the need to reassess the philosophy, content, and structure of graduate training in preventive medicine. The field of preventive medicine faces an identity crisis of its own making, trying to be everything to everybody. The need for funding to overcome the shortage of specialists remains a critical but difficult issue that demands innovative solutions.
