This study examined the role of several personal characteristics in the association between low job control and coronary heart disease among male and female British civil servants. The logistic regression analyses were based on a prospective cohort study (Whitehall II), comprising 6,895 men and 3,413 women, age 35-55 years. Men and women with low job control at baseline had 1.5 to 1.8 higher risks of new heart disease during the 5.3-year follow-up. Psychological attributes, such as hostility, negative affectivity, minor psychiatric disorder, and coping, affected this association very little. The personal characteristics were not confounders, intermediate factors, or effect modifiers. Hence, increasing job control could, in principle, lower risks of heart disease for all employees.

The Iowa record-linkage study was developed to investigate death rates in psychiatric patients, and involved computer matching of death certificates with a roster of patients. A list of all patients admitted to our hospital from 1972 through 1981 was obtained and after removing duplicate entries the list was pared to 5412 names. The record included multiple identifiers (e.g., name, gender, date-of-birth, hospital number). This information was then linked by computer with all Iowa death certificates for the same period; a total of 331 deaths were identified. Patients were assigned to a single psychiatric diagnostic category based on a computer program that reviewed each patient's clinical diagnoses and picked the one with the highest priority in a hierarchy we had created. Age and sex adjusted mortality tables were constructed, allowing us to compute expected numbers of deaths. Relative risk for premature death was greatest among women, and those under 20 years. Risk was associated with all psychiatric diagnoses and was significantly higher among patients of either gender with an organic mental disorder or schizophrenia; women with acute schizophrenia, depressive neuroses, alcoholism, drug abuse, and psychophysiological disorders; and men with neuroses. Death from natural causes, especially from heart disease, was significantly excessive among women, while death from accidents and suicides was excessive for both men and women. The overall SMR was 1.65 (P < 0.001). Most importantly, we found that the greatest excess of mortality occurred within the first 2 years following hospital discharge. Thus, we were able to demonstrate that risk of mortality in general, and of suicide specifically, differed according to age, gender, diagnosis, and portion of the follow-up. We have subsequently used this method to investigate specific risk factors associated with mortality in mood disorders, schizophrenia, and antisocial personality disorder. Findings from these studies are reported.

Regional sympathetic activity can be studied in humans using electrophysiological methods measuring sympathetic nerve firing rates and neurochemical techniques providing quantification of noradrenaline spillover to plasma from sympathetic nerves in individual organs. Essential hypertension: Such measurements in patients with essential hypertension disclose activation of the sympathetic outflows to skeletal muscle blood vessels, the heart and kidneys, particularly in younger patients. This sympathetic activation, in addition to underpinning the blood pressure elevation, most likely also contributes to left ventricular hypertrophy, and to the commonly associated metabolic abnormalities of insulin resistance and hyperlipidaemia. Antihypertensive drugs, such as moxonidine, which act primarily by inhibiting the sympathetic nervous system, should have additional clinical benefits beyond those attributable to blood pressure reduction, in protecting against hypertensive complications. Obesity-related hypertension: Understanding the neural pathophysiology of hypertension in the obese has been difficult. In normotensive obesity, renal sympathetic tone is doubled, but cardiac noradrenaline spillover (a measure of sympathetic activity in the heart) is only 50% of normal. In obesity-related hypertension, there is a comparable elevation of renal noradrenaline spillover, but without suppression of cardiac sympathetics (cardiac sympathetic activity being more than double that of normotensive obese and 25% higher than in healthy volunteers). Increased renal sympathetic activity in obesity may be a 'necessary' cause for the development of hypertension (and predisposes to hypertension development), but apparently is not a 'sufficient' cause. The discriminating feature of the obese who develop hypertension is the absence of the adaptive suppression of cardiac sympathetic tone seen in the normotensive obese. Heart failure: In cardiac failure, the sympathetic nerves of the heart are preferentially stimulated. Noradrenaline release from the failing heart at rest in untreated patients is increased as much as 50-fold, similar to the level seen in the healthy heart during near-maximal exercise. Activation of the cardiac sympathetic outflow provides adrenergic support to the failing myocardium, but at a cost of arrhythmia development and progressive myocardial deterioration. Psychosomatic heart disease: No more than 50% of clinical coronary heart disease is explicable in terms of classical cardiac risk factors. There is gathering evidence that psychological abnormalities, particularly depressive illness, anxiety states, including panic disorder and mental stress, are involved here, 'triggering' clinical cardiovascular events, and possibly also contributing to atherosclerosis development. The mechanisms of increased cardiac risk attributable to mental stress and psychiatric illness are not entirely clear, but activation of the sympathetic nervous system seems to be of prime importance.

BACKGROUND: This study examines the impact of mental illness on the labor market performance of family members of afflicted individuals. Numerous research projects have attempted to measure the impact of mental illness and related disorders on the ill individual, yet have traditionally neglected estimating potential costs accruing to family members of the ill. AIMS OF THE STUDY: Previous research estimating the impact of illness on the time allocation decisions of family caregivers has been limited in scope. I obtain estimates of the impact of mental illness on the probability of labor force participation and hours of work of all family members. The general analysis used in this study will pave the way for more accurate assessments of the costs of all types of illness and the estimates obtained will provide policy makers with a much more complete picture of the costs of mental illness. METHODS: The main empirical work in this study includes a probit estimation of labor force participation and a tobit regression of hours worked (including sample selection correction). The data sample, taken from the 1987 National Medical Expenditure Survey, is also partitioned by gender to clarify effects of family illness on labor supply for both females and males. RESULTS: Adult males are found to increase their probability of labor force participation in the presence of mental illness in the family (all else equal) when the mental illness is accompanied by a chronic physical illness. However, females are surprisingly found to have no significant impact on their probability of being a member of the labor market when a family member is afflicted with mental illness. On the other hand, hours of work are significantly reduced for both females and males when the mentally ill family member is afflicted with additional illnesses (physical and/or mental). DISCUSSION: Previous studies have traditionally not considered the effects of family illness on males because females are typically found to be the primary caregiver when a family member falls ill. The findings in this study indicate that men suffer reductions in their hours of work in an equivalent magnitude to females. Thus, males should not be ignored when estimating the opportunity costs of illness in families. IMPLICATIONS FOR HEALTH POLICIES: Current federal and state policies provide for some of the medical costs and replace some of the lost income of ill individuals, but generally do not support family members who are negatively affected by illness. This research provides evidence supporting the arguments of advocates for policy to ameliorate the financial burden borne by family members of the ill. IMPLICATIONS FOR FUTURE RESEARCH: The estimates obtained in this study show that women and men both need to be studied when determining the effects of family illness on labor supply, and should be studied separately to obtain clear results. Also, future research should include examining particular mental illnesses to see whether there is a higher cost of one over the other (e.g., schizophrenia versus major depression), as this may provide valuable information to policy makers. In addition, comparison of the costs of psychological disorders to chronic physical illnesses (such as cancer and heart disease) should be undertaken.

The authors evaluated the effort of New Jersey jails to plan for the postrelease treatment needs of inmates with mental illness compared with inmates with heart disease and HIV infection or AIDS. Seventy percent of interviewees expressed a belief that release planning for persons with serious mental illness is very or extremely important. However, virtually all the jails reported providing "no real release planning." A majority of the jails provide aftercare plans for fewer than 10 percent of inmates with serious mental illness. A lack of release planning was noted for the other chronic conditions. Release planning for particular chronic problems is most common and complete in facilities with special treatment programs, such as a mental health unit.

Magnetic resonance imaging (MRI) provides detailed images of brain anatomy, with especially clear definition of gray and white matter structures. Several brain MRI studies have suggested that adults with bipolar disorder (BD) are more likely to have "white matter hyperintensities" (WMH) than adults without BD. The disproportionately greater frequency of these lesions in otherwise physically healthy patients suggests that the illness itself, or treatments used to control the illness, may be risk factors for the development of white matter changes. Similarly, WMH may be an etiological factor for some types of BD. In addition to reviewing the relevant literature, this research study attempted to determine whether lithium treatment is associated with an increased prevalence of WMH in young adults with psychiatric illness. To test this hypothesis, we evaluated over 600 brain MRI scans from inpatients at McLean Hospital, Belmont, Massachusetts. We controlled for possible confounding variables such as age, vascular disease, substance abuse, and markers of illness severity. We found that individuals with BD were no more likely to have WMH than other psychiatric patients. Lithium use was nonsignificantly associated with the presence of WMH. A multivariate regression model for the presence of WMH showed that heart disease, female gender, and multiple psychiatric admissions were significant predictors of WMH. This study does not support previous findings that BD, compared to other psychiatric illnesses, was associated with increased risk of WMH. Lithium use may be subtly associated with WMH. Our results are consistent with previous research that found an association between cardiovascular disease, advanced age, and the presence of WMH, though our analysis appears to be unique in its inclusion of cardiovascular disease as a risk factor in young adults with psychiatric illness.

For decades, there have been reports of shorter life expectancy among those with mental illness, especially those with more serious psychiatric disorders. The purpose of this study was to compare the risk of mortality among Medicaid beneficiaries, aged 18-64 years, treated for mental illness to a comparable group who were not mentally ill and to the general population. The data used were from the Massachusetts Division of Medical Assistance and records of deaths from the Department of Public Health in Massachusetts. Individuals treated for both psychiatric illness and substance use disorders (dual diagnoses) were compared separately from those whose treatment was only for a psychiatric disorder. For all Medicaid beneficiaries, the most common causes of death were attributed to heart disease and cancer. When compared to the general population, adjusted odds ratios estimated death by injury to be twice as likely among the mentally ill when compared to the general population. Medicaid beneficiaries with dual diagnoses are 6-8 times more likely to die of injury, primarily poisoning, than their counterparts treated for medical conditions only.

This study was designed to compare the effects of fluoxetine and imipramine on fasting blood glucose (FBG) in patients with major depressive disorder. Sixty nondiabetic patients with major depressive disorder (based on Diagnostic and Statistical Manual of Mental Disorders, Fourth Edition criteria) entered this randomized, double-blind study. Patients did not receive any medication affecting serum FBG levels for at least 2 weeks before the initiation of the study. Patients were assigned to receive 20 to 40 mg/d of fluoxetine or 75 to 200 mg/d of imipramine for 8 weeks. Pregnant women and patients with diabetes mellitus and a history of any major heart disease were excluded from this study. Additionally, none of the patients should have received electroconvulsive therapy within 6 months before the initiation of the antidepressants. FBG levels were measured at the initiation, as well as 4 and 8 weeks after starting antidepressants. Nineteen patients in the fluoxetine and 24 patients in the imipramine groups completed the study. In the fluoxetine group, FBG level was decreased from 88.5 mg/dL (baseline) to 85.0 mg/dL at week 4 (P = 0.73), and to 79.8 mg/dL at week 8 (P < 0.001). On the other hand, in the imipramine group, FBG level was increased from 86.96 mg/dL (baseline) to 89.71 mg/dL at week 4 (P = 0.079), and to 96.90 mg/dL at week 8 (P < 0.001). This 8-week study showed that FBG levels may decrease in depressive patients receiving fluoxetine and may increase in those patients treated with imipramine. Therefore, it is suggested to measure and monitor FBG before initiation and during treatment with fluoxetine and imipramine.

Research in the UK has suggested that people in lower social classes or from poorer neighbourhoods are less likely than their more socially advantaged counterparts to agree that health and life expectancy are worse among more deprived population groups. The small body of previous research has either used qualitative approaches or coded open-ended responses to survey questions about causes of health and illness or of inequalities between areas. We examined lay perceptions by asking a direct question and using a quantitative, multivariate approach. Residents in three age groups (25, 45 and 65 years old) living in two socially contrasting localities in Glasgow, Scotland, were asked who were more likely to have accidents, cancer, heart disease, mental illness, to be fitter, and to live longer: rich people, poor people, or both equally. Across all the health categories, those in lower social classes or from poorer neighbourhoods were equally or less likely than their more socially advantaged counterparts to say the poor had worse health. In a model containing age, sex, class and locality, those in lower social classes and in the poorer locality were significantly less likely to say that richer people live longer (OR: 0.5). We have therefore confirmed earlier observations that those most at risk of ill health may be less likely to acknowledge the social gradient in health. We suggest a need to examine this apparent paradox in other contexts and in more detail, using both quantitative and qualitative approaches.

This cross-sectional psychiatric and cardiological study compared patients with and without coronary artery disease (CAD) with respect to psychiatric morbidity, psychological factors, pain characteristics, medical morbidity and the prevalence of coronary risk factors. The 199 participants had been referred to cardiological outpatient clinics for the investigation of chest pain and had no history of heart disease. Current panic disorder occurred significantly more often in non-CAD patients (41% vs. 22%). No significant differences were found for other psychiatric disorders and psychological variables. Non-CAD patients reported significantly longer histories of pain and a higher prevalence of atypical chest pain. In other respects, there were surprisingly few differences between the groups. High morbidity of both psychiatric disease (pain disorder, 19%; any current psychiatric disorder, 72%) and somatic conditions (musculoskeletal disease, 33%; dyspepsia, 23%) was found with no significant differences between the groups. In these patients, multifactorial complaints may explain chest pain in both patient groups. The physicians should attend to psychiatric disorders in non-CAD as well as in CAD patients.
