Cardiovascular effects of social support in the work place: twenty-four-hour ECG monitoring of men and women

Psychosocial work characteristics, such as work demand, work control, and social support at work, have been shown to be related to the development of coronary heart disease in epidemiological studies. However, the mechanisms which mediate the social and psychological effects on the cardiovascular system are not known. We have studied the direct cardiovascular effects of psychosocial work environment characteristics in 148 working men and women, representing seven different occupational groups (physicians, teachers, musicians, policemen, train engineers, prison personnel, and saw mill workers). Besides standardized measures of work demand, work control, and social support, ambulatory 24-hour monitoring of electrocardiograms in the customary work and home environment was performed. Systolic and diastolic blood pressure were measured as well as other standard physiologic risk factors for coronary heart disease. Mean heart rates were found to be significantly higher in persons reporting low social support at work. This effect was maintained during working hours as well as during leisure time and rest. Of the other related physiologic risk factors, systolic, but not diastolic blood pressure was found to be higher in persons reporting low social support. Smoking, alcohol consumption and relative body mass index were not related to social support at work. Controlling for age, sex and physical strain at work, strengthened the association of low social support with elevated heart rates.     

Psychosocial health risk factors and resources of medical students and physicians: a cross-sectional study

Background  

Epidemiological data indicate elevated psychosocial health risks for physicians, e. g., burnout, depression, marital disturbances, alcohol and substance abuse, and suicide. The purpose of this study was to identify psychosocial health resources and risk factors in profession-related behaviour and experience patterns of medical students and physicians that may serve as a basis for appropriate health promoting interventions.     

Brief report: parent report about health care use: relationship to child's and parent's psychosocial problems.

OBJECTIVE: To investigate the potential utility of asking parents about health care utilization as a means of identifying individuals at risk for psychosocial problems. METHOD: Parents of 366 children ages 2 to 16 completed questionnaires about their own, their child's, and their family's psychosocial functioning and health care utilization. RESULTS: Children and parents with high health care utilization were more likely to have psychosocial problems than those with low health care utilization. Sensitivity and specificity of health care utilization as a marker for psychosocial problems ranged from 43.8% to 68.8%. CONCLUSIONS: Although high rates of child health care utilization are related to the presence of psychosocial problems, use of this measure alone could result in many false-positive and false-negative identifications. Rather, use of health care utilization data in conjunction with other screening measures may be useful for alerting physicians to the possibility of both child and parent psychosocial problems.     

Sources of variability in John Henryism

OBJECTIVES: To decompose sources of individual differences in coping as measured by John Henryism among African Americans. METHODS: Analyses described in this study are based on the pairwise responses from 180 pairs of same-sex, African-American twin pairs who participated in the Carolina African-American Twins Study of Aging (CAATSA). The sample consisted of 85 monozygotic (MZ) and 95 dizygotic (DZ) twin pairs. RESULTS: Environmental factors account for most of the variance (65%) in John Henryism scores, with the remaining variance attributable to additive genetic factors (35%). The test of the genetic component suggested that the 35% represented a statistically significant proportion of variance. CONCLUSIONS: The vast majority of recent studies on African Americans and health outcomes have focused on the impact of psychosocial factors on diseases such as hypertension and diabetes, with relatively little attention to possible genetic contributors. Previous research on psychosocial indices and their relationship to cardiovascular health among African Americans has focused on assessment and epidemiological explorations rather than understanding the etiology of variability in such measures.     

Type A behavior, social support, and coronary risk: interaction and significance for mortality in cardiac patients

The 10-year prognostic significance of psychosocial as well as medical risk factors was examined in 150 middle-aged Swedish men. Type A behavior was assessed by means of the Structured Interview; work demand, social support, and other psychosocial factors were registered through standardized questionnaires. The clinical investigation included a standard physical examination, a frontal and sagittal chest x-ray, fasting serum lipids, glucose, and urate, and a 24-hour ambulatory ECG monitoring. Thirty-seven men died during follow-up. Mortality was similar in men with Type A (24%) and Type B (22%) behavior. In multivariate analyses, lack of social support/social isolation was an independent mortality predictor in Type A, but not in Type B men. In both groups, a high frequency of ventricular ectopic beats on 24-hour ECG monitoring and a poor self-rated general health predicted mortality over the 10-year period. The 10-year mortality experience of socially isolated Type A men was 69% and that of socially integrated Type A men was 17% (p less than 0.05). The findings offer a possible explanation for the observed inconsistencies between intervention and follow-up studies of Type A behavior and coronary heart disease. It is suggested that an important effect of Type A modification programs is to increase the availability of social support. This could be the mechanism through which Type A modification exerts its main effects on cardiovascular health.     

Health change in air traffic controllers: a prospective study. I. Background and description

The background, rationale, and design of a 3-year prospective study of health change in 416 air traffic controllers is described. This study was designed to assess the relevant variables that might predict future physical and psychological health change. This report describes the major variables that were assessed in all participants, which included endocrine, cardiovascular, and behavioral differences in response to work, the occurrence of significant life events, work attitude and morale, availability and usefulness of psychosocial supports, and job commitment and performance. Future reports will describe the contribution, both individually and interactively, of these various factors to the risk for future illness. A major hypothesis to be tested by this study is that health change among air traffic controllers can be predicted by differential responsivity to work.     

Do patients talk differently to male and female physicians? A meta-analytic review

A meta-analytic review was undertaken of seven observational studies which investigated the relation between physician gender and patient communication in medical visits. In five of the studies the physicians were in general practice, internal medicine, or family practice and were seeing general medical patients, and in two of the studies the physicians were in obstetrics-gynecology and were seeing women for obstetrical or gynecological care. Significant findings revealed that, overall, patients spoke more to female physicians than to male physicians, disclosed more biomedical and psychosocial information, and made more positive statements to female physicians. Patients also were rated as more assertive toward female physicians and tended to interrupt them more. Several results were weaker, or even reversed, in the two obstetrics-gynecology studies. Partnership statements were made significantly more often to female than male physicians in general medical visits but not in obstetrical-gynecological visits.     

The impact of depressive symptoms and psychosocial factors on medication adherence in cardiovascular disease

OBJECTIVE: This study sought to determine the influence of depression and psychosocial factors on medication adherence in cardiovascular disease. METHODS: A questionnaire including measures of depression, beliefs about medicines, health locus of control and adherence to medication (self-report) was completed by 122 outpatients attending a cardiac clinic. RESULTS: Analysis revealed that 14.8% of participants were non-adherent with their cardiovascular medication and 41.7% had scores indicative of depressive symptoms as determined by the Center for Epidemiological Studies Depression Scale (CES-D). Higher scores on this scale and strong concern scores on the Beliefs about Medicines Questionnaire about the potential adverse effects of using medication as prescribed were found to be associated with self-reported non-adherence. DISCUSSION AND CONCLUSION: These findings imply that the relationship between depressive symptoms in cardiovascular patients, together with certain psychosocial factors, could have negative consequences for adherence to medication. PRACTICE IMPLICATIONS: Given that there is emerging evidence to suggest an association between depression and medication non-adherence, healthcare professionals should consider this when dealing with cardiovascular patients.     

Social support and risk for cardiovascular disease and cancer: a qualitative review examining the role of inflammatory processes

Abstract

Social support has long been recognised as a protective factor against life stress and poor health. However, the mechanism through which it exerts its effects is unknown. As the role of inflammation in the development of diseases, such as cardiovascular disease and cancer, has gained significant attention over the last decade, it has been hypothesised that psychosocial factors affect disease progression by influencing the inflammatory process (Sher, 2000). Social support is one such factor that could influence the immune system response, leading to differing disease outcomes. A meditational model is proposed, in which social support affects the level of inflammation an individual experiences, producing differing health outcomes. A critical review of the literature linking social support and inflammation was conducted to help elucidate the relation between these two variables as possible causal factors of disease progression in patients with cardiovascular disease or cancer. Results of the studies were mixed, suggesting that social support and inflammation may be linked, though it is premature to claim that inflammation is the mechanism through which social support exerts salubrious effects on health.     

Impact of management change and an intervention program on health care personnel

BACKGROUND: There has been a major shift in the organization and responsibility for the provision of geriatric care in Sweden. This was believed to be stressful. We therefore decided to launch a controlled intervention program on health care personnel aimed at enhancing their adaptation and ability to cope. The purpose of this study was to assess the impact of management change on psychosocial parameters of health care personnel and the effects, if any, of a structured intervention program. METHODS: Two separate wards were randomly allocated to be either intervention (I) or control (C) ward. The I-ward personnel were subjected to a psychologist's structured 10-session intervention program for 20 weeks. The program consisted of an initial educational part followed by a practical problem-solving discussion part. A structured questionnaire on psychosocial issues was answered by the participants before (0 weeks), immediately after (20 weeks), and 10 weeks after the intervention (30 weeks). RESULTS: There were no significant changes in the psychosocial parameters of the C-ward personnel. In the I-ward, however, there was a significant increase in work demand as well as in positive feelings about work, as compared to the C-ward at the 30-week follow-up. There was also significantly better work comfort in the I-ward. CONCLUSIONS: We did not find any anticipated negative psychosocial effects on health care personnel undergoing an organizational change. However, by offering a structured intervention program to one group of health care personnel, we found some positive psychosocial effects. Future research is needed to pinpoint which factor or factors in the intervention program were the most crucial for the effects to occur.     

Factors affecting help-seeking during depression in a community sample

Little is known about factors that influence community residents to seek professional help while experiencing diagnosable episodes of depression. The present study utilized longitudinal data from 96 female subjects to examine whether clinical and psychosocial features of a recent depressive episode, as well as preexisting psychiatric and psychosocial characteristics, could distinguish between individuals who (a) did and did not seek help during their episode and (b) chose to consult one professional source rather than another. Results showed that less than half of the sample sought professional help. Few variables could distinguish subjects who sought help from those who did not. Instead, subjects consulting mental health specialists were more clinically impaired and had fewer psychosocial assets than both those consulting nonpsychiatric physicians and those seeking no help. Subjects in the latter two groups were indistinguishable from one another on the assessed variables. Results were cross-validated with a smaller sample of male community residents.     

Psychosocial stress and cardiovascular disease. Part 3: Clinical and policy implications of research on the transcendental meditation program

Cardiovascular disease (CVD) remains the leading cause of death in the United States today and a major contributor to total health care costs. Psychosocial stress has been implicated in CVD, and psychosocial approaches to primary and secondary prevention are gaining research support. This third article in the series on psychosocial stress and CVD continues the evaluation of one such approach, the Maharishi Transcendental Meditation program, a psychophysiological approach from the Vedic tradition that is systematically taught by qualified teachers throughout the world. Evidence suggests not only that this program can provide benefits in prevention but also that it may reduce CVD-related and other health care expenses. On the basis of data from the studies available to date, the Transcendental Meditation program may be responsible for reductions of 80% or greater in medical insurance claims and payments to physicians. This article evaluates the implications of research on the Transcendental Meditation program for health care policy and for large-scale clinical implementation of the program. The Transcendental Meditation program can be used by individuals of any ethnic or cultural background, and compliance with the practice regimen is generally high. The main steps necessary for wider adoption appear to be: (1) educating health care providers and patients about the nature and expected benefits of the program, and (2) adjustments in public policies at the state and national levels to allow this program to be included in private and public health insurance plans.     

Psychosocial stress and cardiovascular disease Part 2: effectiveness of the Transcendental Meditation program in treatment and prevention

Psychosocial stress is a nontraditional risk factor for cardiovascular morbidity and mortality that may respond to behavioral or psychosocial interventions. To date, studies applying such interventions have reported a wide range of success rates in treatment or prevention of cardiovascular disease (CVD). The authors focus on a natural medicine approach that research indicates reduces both psychosocial and traditional risk factors for cardiovascular disease-the Transcendental Meditation (TM) program. Randomized controlled trials, meta-analyses, and other controlled studies indicate this meditation technique reduces risk factors and can slow or reverse the progression of pathophysiological changes underlying cardiovascular disease. Studies with this technique have revealed reductions in blood pressure, carotid artery intima-media thickness, myocardial ischemia, left ventricular hypertrophy, mortality, and other relevant outcomes. The magnitudes of these effects compare favorably with those of conventional interventions for secondary prevention.     

Sleep complaints in middle‐aged women and men: the contribution of working conditions and work–family conflicts

This study aimed to examine how physical working conditions, psychosocial working conditions and work–family conflicts are associated with sleep complaints, and whether health behaviours explain these associations. We used pooled postal questionnaire surveys collected in 2001–2002 among 40–60‐year‐old employees of the City of Helsinki (n = 5819, response rate 66%). Participants were classified as having sleep complaints if they reported sleep complaints at least once a week on average (24% of women and 20% of men). Independent variables included environmental work exposures, physical workload, computer work, Karasek’s job strain and work–family conflicts. Age, marital status, occupational class, work arrangements, health behaviours and obesity were adjusted for. Most working conditions were associated strongly with sleep complaints after adjustment for age only. After adjustment for work–family conflicts, the associations somewhat attenuated. Work–family conflicts were also associated strongly with women’s [odds ratio (OR) 5.90; confidence interval (CI) 4.16–8.38] and men’s sleep (OR 2.56; CI 1.34–4.87). The associations remained robust even after controlling for unhealthy behaviours, obesity, health status, depression and medications. Physically strenuous working conditions, psychosocial job strain and work–family conflicts may increase sleep complaints. Efforts to support employees to cope with psychosocial stress and reach a better balance between paid work and family life might reduce sleep complaints. Sleep complaints need to be taken into account in worksite health promotion and occupational health care in order to reduce the burden of poor sleep.     

A systematic review of measures of therapeutic engagement in psychosocial and psychological treatment

This article reports a systematic review of engagement measures for psychosocial therapy. MEDLINE, EMBASE, and PsycINFO databases were searched to identify English-language studies (published 1980 to February 2010) that reported on an instrument/rating scale to measure engagement in psychosocial treatment for mental health difficulties. Forty-seven studies were identified, reporting information on 40 measures of treatment engagement. Although our findings suggest that therapeutic engagement appears to be considered an important construct to assess, they also reveal that there is little consensus in the definition of engagement employed. Few measures are generalizable across treatment settings and clinical populations, and limited information is reported on the indices of reliability and validity. It is concluded that further work is required to develop adequate measures of therapeutic engagement.     

General practitioners and occupational health services.

BACKGROUND: Occupational physicians and general practitioners often appear to differ in their attitudes to the provision of health screening, health promotion and vaccination in the workplace. AIM: This study aimed to explore the attitudes of occupational physicians and general practitioners to particular aspects of workplace health services. METHOD: Anonymous piloted postal questionnaires were sent to 400 UK general practitioners and 300 occupational physicians. RESULTS: Questionnaires were returned by 260 general practitioners (65%) and 223 occupational physicians (74%). There are differences between the specialties in attitude to specific health screening and vaccination at work, and to the role of occupational health services in helping the disabled, but greater agreement on the usefulness of workplace health promotion. CONCLUSION: General practitioners may misunderstand the role, responsibilities and priorities of occupational health services. Further educational work needs to be done to overcome communication difficulties between the specialties.     

Symptom reporting and self-rated health among women in mid-life: The role of work characteristics and family responsibilities

This study investigated how socioeconomic factors and psychosocial conditions are related to self-reported health among 43-year-old women representing the general Swedish population (N = 569). Odds ratios and multiple logistic regression analyses were used for associations and effect modification, adjusted for symptom reporting in adolescence. Poor self-reported health was predicted by low income, financial worries, and job strain, as well as combined exposure to a high level of unpaid household work and job strain (double burden). In conclusion, poor psychosocial conditions related to working life, as well as to the combined impact of paid and unpaid work were revealed to be risk factors for poor self-reported health among middle-aged women. These results highlight the need for improving women's work conditions, as well as designing family policies that promote a better sharing of unpaid household tasks and responsibilities between spouses.

Feelings of professional fulfilment and exhaustion in mental health personnel: the importance of organisational and individual factors

BACKGROUND: Mental health personnel are at high risk for mental illness, burnout and suicide. Previous studies of this group of professionals have indicated the importance of organisational factors in explaining burnout, or exhaustion, and work satisfaction. This study looks more systematically at the contribution of organisational and individual factors to work-related exhaustion and to professional fulfillment, an expanded version of job satisfaction. METHODS: A cross-sectional study of 1, 051 psychiatrists and mental health nurses in the city of Stockholm was carried out by postal questionnaire with a previously validated instrument. Multiple and logistic regressions were used to identify predictors of exhaustion and professional fulfillment. RESULTS: Organisational characteristics were found to be more important than individual characteristics in predicting exhaustion and professional fulfillment in mental health professionals. CONCLUSIONS: The results indicate that the psychosocial work environment and well-being of mental health professionals can be improved by concentrating on organisational factors such as efficiency, personal development and goal quality.
