Are stress related factors associated with alcohol intake?

Moderate alcohol consumption is related to reduced risks of coronary heart disease and all-cause mortality. Our goal is to advance our understanding of the associations between stress-related factors and alcohol consumption, using cutoff points for alcohol intake that reflect health benefits rather than health risks. Cross-sectional data were used from 4,131 respondents (age 20-65 years) participating in a cohort study in the Netherlands on psychosocial factors and cancer risk. Analyses were performed among drinkers only, for men and women separately. Heavy alcohol intake (>/= 3 glasses per day for men, >/= 2 glasses per day for women) was associated with only a few stress-related factors in multivariate analyses. No significant associations between the total amount of stressors and alcohol intake were found. We conclude that stress-related factors are only marginally associated with a heavy alcohol intake compared with fair drinking, using the safe limits of drinking as cutoff point.

Do depressive episodes lead to accumulation of vulnerability in the elderly?

The vulnerability-accumulation (or scarring) hypothesis postulates that the experience of depression induces a lasting increase in vulnerability, and through this raises the risk of recurrence. We examined the validity of the vulnerability-accumulation model for depressive episodes in later life. The sample comprised 26 elderly persons who had remitted from a depressive episode and 96 control respondents who were all selected from the participants of a large community survey among persons aged 57 years or more. Several psychosocial vulnerability indicators were assessed premorbidly, during the depressive episode and after remission. High levels of psychological distress, low life satisfaction, chronic somatic diseases, high neuroticism, and low scores on extraversion, mastery, and self-efficacy appeared to be predictors of depression in this sample. During the depressive episode, psychological distress was higher and life satisfaction, physical, role, and social functioning, as well as feelings of self-efficacy lower than before the episode. Physical and role functioning, cognitive function, and self-efficacy were lower after remission compared to premorbid levels, but (other) personality indices had not changed after remission compared to premorbid levels. Furthermore, we failed to find differences between first and recurrent episodes. Support for the vulnerability-accumulation model was limited at the most. Although psychosocial scarring may occur in the elderly, our findings tentatively suggest that this accumulation does not manifest itself in major vulnerability indicators such as neuroticism.

The role of depressive symptoms in recovery from injuries to the extremities in older persons. A prospective study.

BACKGROUND: Previous research suggested that depressive symptoms play a role in recovery after hip fracture. However none of these studies were prospective and included only patients with hip fractures. OBJECTIVE: To examine the effect of depressive symptoms on the recovery of (instrumental) activities of daily living after fall-related injuries to the extremities in older persons. DESIGN: Prospective cohort study. METHODS: Data were collected from 168 older persons at baseline, prior to their injuries (hip fractures, other fractures or contortions and dislocations), and 8 weeks, 5 months and 12 months after their accident. Hierarchical multiple regression analysis was used to study the impact of depressive symptoms (as assessed with the Hospital Anxiety and Depression Scale; HADS) on disability (as assessed with the Groningen Activity Restriction Scale; GARS) after the injury while adjusting for several covariates. RESULTS: Depressive symptoms at baseline were not predictive for disability after the injury when covariates were taken into account. However, depressive symptoms 8 weeks after the fall were significantly related to disability at 8 weeks, 5 months and even 12 months after the injury. In addition, disability levels before the injury were highly predictive for recovery later on. Severity of injury was particularly predictive for disability at 8 weeks while age (which may generally represent the amount of physiological reserve) predicted disability at 5 and 12 months after the injury. Cognitive functioning 8 weeks post-injury was, in contrast to previous research, not predictive for recovery when covariates were taken into account. CONCLUSIONS: Pre-injury levels of disability and post-injury depressive symptoms are associated with recovery and may warrant concern and special attention in clinical practice.

Psychosocial and vascular risk factors of depression in later life.

BACKGROUND: Research on the aetiology of late-life depression has typically focused on either risk factors from the psychosocial stress-vulnerability domain or degenerative biological changes (for instance, vascular disease). We examined whether vascular risk factors could be interpreted within the stress-vulnerability model of depression. METHODS: The data came from a case-control design, nested in a community survey of elderly people. We compared 83 persons with a recently started episode of major or minor depression with 83 controls, with respect to the occurrence of stressful life events, long-term difficulties, neuroticism, and vascular risk factors (hypertension, heart disease, stroke). RESULTS: The (non-significant) association of vascular risk factors and onset of depressive episodes was not modified by neuroticism or the presence of long-term difficulties. Quite unexpectedly, vascular risk factors seemed to neutralize the depressogenic effect of stressful life events. The effect of vascular risk was significantly stronger in depressive episodes not preceded by a life event than in onsets following an event. CONCLUSIONS: Vascular risk factors cannot be interpreted within the stress-vulnerability model, but represent another pathway to depression. Why vascular risk factors reduce the depressogenic effect of stressful life events is not clear. Replication is critical to exclude the possibility of a chance finding.

Survey non-response in the Netherlands: effects on prevalence estimates and associations.

PURPOSE: Differences in respondent characteristics may lead to bias in prevalence estimates and bias in associations. Both forms of non-response bias are investigated in a study on psychosocial factors and cancer risk, which is a sub-study of a large-scale monitoring survey in the Netherlands. METHODS: Respondents of a cross-sectional monitoring project (MORGEN; N = 22,769) were also asked to participate in a prospective study on psychosocial factors and cancer risk (HLEQ; N = 12,097). To investigate diverse aspects of non-response in the HLEQ on prevalence estimates and associations are studied, based on information gathered in the MORGEN-project. RESULTS: A response percentage of 45% was obtained in the MORGEN-project. Response rates were found to be lower among men and younger people. The HLEQ showed a response percentage of 56%, and respondents reported higher socioeconomic status, better subjective health and healthier lifestyle behaviors than non-respondents. However, associations between smoking status and either socioeconomic status or subjective health based on respondents only were not statistically different from those based on the entire MORGEN-population. CONCLUSION: Non-response leads to bias in prevalence estimates of current smoking, current alcohol intake, and low physical activity or poor subjective health. However, non-response did not cause bias in the examined associations.

A cross-cultural study of the structure of comorbidity among common psychopathological syndromes in the general health care setting.

This study presents analyses of 7 common psychopathological syndromes in the World Health Organization (WHO) Collaborative Study of Psychological Problems in General Health Care (T. B. Ustun & N. Sartorius, 1995). Data on depression, somatization, hypochondriasis, neurasthenia, anxious worry, anxious arousal, and hazardous use of alcohol were analyzed for 14 countries (Ns for each country ranged from 196 to 800). Four models were evaluated: a 1-factor model; a 2-factor model in which all syndromes except hazardous use of alcohol represented internalizing problems; and two 3-factor models. The 2-factor model fit best. These results extend previous research on the 2-factor model to the current complaints of attendees of general health care clinics, to a new set of syndromes, and to a variety of both Western and non-Western countries.

Depression in older people after fall-related injuries: a prospective study.

BACKGROUND: objectives of the study were i) to describe changes in depression in independently living people aged 57 or older with fall-related injuries, and ii) to examine the effect of incomplete recovery of physical functions on depression one year post-injury. METHOD: prospective cohort-study, including a pre-injury baseline and post-injury assessments at 8 weeks, 5 months and one year. The sample consisted of 159 patients who sustained various kinds of fall-related injuries to the limbs. Physical functioning was measured by the Groningen Activity Restriction Scale, depression by the Hospital Anxiety and Depression Scale. Additional variables in the study were age, gender, chronic medical conditions and severity of the injury (three level-groups). Pre- and post-injury levels of depression were compared by using Student's t-test and effect size indices. Hierarchical multivariate regression analysis was used to examine the contribution of change in physical functioning between baseline and one year post-injury to depression one year post-injury. RESULTS: severity of the injury was not associated with depression. Mean depression levels of all patients remained stable until 5 months post-injury but increased between 5 months and one year. Physical functioning decreased between baseline and 8 weeks post-injury, increased between 8 weeks and 5 months but did not change after 5 months. One year post-injury, both disability and depression were higher than at baseline. Change in physical functioning between baseline and one year post-injury accounted for 19% of the variance in depression explained by the regression model. CONCLUSIONS: depressive reactions did not occur as long as patients experienced improvement in physical functioning but became manifest as recovery appeared to stagnate. No significant differences in this respect were found between hip fracture patients and patients with other injuries.

The role of perceived control in the process of older peoples' recovery of physical functions after fall-related injuries: a prospective study.

This study examined the predictive role of perceived control in recovery of physical functions after fall-related injuries in a cohort of 165 older people who had completed preinjury baseline assessments including physical functioning and perceived control. Follow-up assessments of functioning were made at 8 weeks, 5 months, and 12 months. Indicators for perceived control were mastery and self-efficacy expectations. Physical functioning referred to self-reported difficulties with activities of daily living. Covariates included age, gender, level of education, preinjury health status, preinjury levels of social support and disability, and, additionally, the severity of the injury. Separate regression equations were estimated with disability as outcome at 8 weeks, 5 months, and 12 months post injury. Although significant at 8 weeks and borderline significant at 5 months post injury, the predictive role of perceived control appeared to be comparatively small. Preinjury levels of disability were highly predictive for disability at 8 weeks, 5 months, and 12 months post injury. The severity of the injury is the predominant contributor to disability in the short term but becomes insignificant over time, whereas the influence of age on recovery becomes important after 5 months.

Impact of birth weight and genetic liability on psychopathology in children of bipolar parents.

OBJECTIVE: To test different models for ways in which birth weight and familial loading influence the risk for psychopathology in bipolar offspring. METHOD: DSM-IV diagnoses of 140 bipolar offspring (12-21 years of age) were assessed with the K-SADS-PL. Parents were interviewed using the Family History-Research Diagnostic Criteria to determine familial loading of mood and substance use disorders. Parents reported the birth weight of their offspring. Age- and sex-adjusted hazard ratios were calculated. RESULTS: Low birth weight was associated with mood and non-mood disorders in bipolar offspring (hazard ratio = 0.6, confidence interval = 0.4-0.8), even after controlling for familial loading of unipolar disorder, bipolar disorder, or substance use disorder. There were no significant interactions between birth weight and familial loading of unipolar disorder, familial loading of bipolar disorder, and familial loading of substance use disorder. CONCLUSIONS: Birth weight is associated with mood as well as non-mood disorders. This association is independent from the association of familial loading of mood and substance use disorder with mood- and non-mood disorders in bipolar offspring.

Comorbid mental disorders account for the role impairment of commonly occurring chronic physical disorders: results from the National Comorbidity Survey.

Most health and work productivity studies have focused on individual conditions without considering comorbidity. We illustrate the implication of this neglect by examining the effects of comorbid mental disorders on role impairment (number of sickness absence and work cut-back days in the past month) among people with chronic physical disorders. A nationally representative household survey of 5877 respondents assessed current mental and physical disorders and role impairments. Four physical disorders were sufficiently common to be studied: hypertension, arthritis, asthma, and ulcers. All 4 physical disorders were associated with significant role impairments in bivariate analyses. However, further analysis showed that these impairments were almost entirely confined to cases with comorbid mental disorders. Effectiveness trials in workplace samples are needed to evaluate the cost-effectiveness of treating comorbid mental disorders among workers with chronic physical disorders.

Temporal and reciprocal relationship between IADL/ADL disability and depressive symptoms in late life.

A strong association between functional disability and depressive symptoms in older people has frequently been reported. Some studies attribute this association to the disabling effects of depression, others to the depressogenic effects of physical health-related disability. The authors examined the reciprocal effects between depressive symptoms and functional disability and their temporal character in a community-based cohort of 753 older people with physical limitations who were assessed at yearly intervals. They compared structural equation models that differed in terms of direction and speed of effects between patient-reported disability in instrumental and basic activities of daily living (IADL/ADLs) and depressive symptoms. The association between disability and depression could be separated into three components: (a) a strong contemporaneous effect of change in disability on depressive symptoms, (b) a weaker 1-year lagged effect of change in depressive symptoms on disability (probably indirect through physical health), and (c) a weak correlation between the trait (or stable) components of depression and disability. IADL/ADL disability and depressive symptoms are thus mutually reinforcing over time. Compensatory forces like effective treatment and age-related adaptation may protect elders against this potential downward trend. To improve quality of life in elderly adults, treatment should target disability when it is new and depression when it is persistent.

Duration of major depressive episodes in the general population: results from The Netherlands Mental Health Survey and Incidence Study (NEMESIS).

BACKGROUND: Data on the duration of major depressive episodes (MDE) in the general population are sparse. AIMS: To assess the duration of MDE and its clinical and socio-demographic determinants in a study group drawn from the general population with newly originated episodes of major depression. METHOD: The Netherlands Mental Health Survey and Incidence Study is a prospective epidemiological survey in the adult population (n=7076), using the Composite International Diagnostic Interview. Duration of MDE over 2 years was assessed with a Life Chart Interview. RESULTS: The median duration of MDE was 3.0 months; 50% of participants recovered within 3 months, 63% within 6 months, 76% within 12 months and nearly 20% had not recovered at 24 months. Determinants of persistence were severity of depression and comorbid dysthymia. A recurrent episode predicted shorter duration. CONCLUSIONS: Although half of those affected with MDE recovered rapidly, the risk of chronicity (duration 24 months or more) was considerable. This underlines the necessity of diagnosing and treating those at risk.

Treatment of depression after myocardial infarction and the effects on cardiac prognosis and quality of life: rationale and outline of the Myocardial INfarction and Depression-Intervention Trial (MIND-IT).

BACKGROUND: Patients with a depressive disorder after myocardial infarction (MI) have a significantly increased risk of major cardiac events. The Myocardial INfarction and Depression-Intervention Trial (MIND-IT) investigates whether antidepressive treatment can improve the cardiac prognosis for these patients. The rationale and outline of the study are described. METHODS: In this multicenter randomized clinical trial, 2140 patients admitted for MI are screened for depressive symptoms with a questionnaire 0, 3, 6, 9, and 12 months after MI. Patients with symptoms undergo a standardized psychiatric interview. Those with a post-MI depressive episode are randomized to intervention (ie, antidepressive treatment; n = 190) or care-as-usual (CAU; n = 130). In the intervention arm, the research diagnosis is to be confirmed by a psychiatrist. First-choice treatment consists of placebo-controlled treatment with mirtazapine. In case of refusal or nonresponse, alternative open treatment with citalopram is offered. In the CAU arm, the patient is not informed about the research diagnosis. Psychiatric treatment outside the study is recorded, but no treatment is offered. Both arms are followed for end points (cardiac death or hospital admission for MI, unstable angina, heart failure, or ventricular tachyarrhythmia) during an average period of 27 months. Analysis is on an intention-to-treat basis. CONCLUSION: The MIND-IT study will show whether treatment of post-MI depression can improve cardiac prognosis.

Grading the severity of chronic pain.

This research develops and evaluates a simple method of grading the severity of chronic pain for use in general population surveys and studies of primary care pain patients. Measures of pain intensity, disability, persistence and recency of onset were tested for their ability to grade chronic pain severity in a longitudinal study of primary care back pain (n = 1213), headache (n = 779) and temporomandibular disorder pain (n = 397) patients. A Guttman scale analysis showed that pain intensity and disability measures formed a reliable hierarchical scale. Pain intensity measures appeared to scale the lower range of global severity while disability measures appeared to scale the upper range of global severity. Recency of onset and days in pain in the prior 6 months did not scale with pain intensity or disability. Using simple scoring rules, pain severity was graded into 4 hierarchical classes: Grade I, low disability--low intensity; Grade II, low disability--high intensity; Grade III, high disability--moderately limiting; and Grade IV, high disability--severely limiting. For each pain site, Chronic Pain Grade measured at baseline showed a highly statistically significant and monotonically increasing relationship with unemployment rate, pain-related functional limitations, depression, fair to poor self-rated health, frequent use of opioid analgesics, and frequent pain-related doctor visits both at baseline and at 1-year follow-up. Days in Pain was related to these variables, but not as strongly as Chronic Pain Grade. Recent onset cases (first onset within the prior 3 months) did not show differences in psychological and behavioral dysfunction when compared to persons with less recent onset. Using longitudinal data from a population-based study (n = 803), Chronic Pain Grade at baseline predicted the presence of pain in the prior 2 weeks. Chronic Pain Grade and pain-related functional limitations at 3-year follow-up. Grading chronic pain as a function of pain intensity and pain-related disability may be useful when a brief ordinal measure of global pain severity is required. Pain persistence, measured by days in pain in a fixed time period, provides useful additional information.

Depression following myocardial infarction: first-ever versus ongoing and recurrent episodes.

BACKGROUND: Depression following myocardial infarction (MI) can be a first-ever episode for some, whereas for others, it may represent a recurrent episode or one that was present at the onset of the infarction. We investigated if there are differences in pre- and post-MI characteristics between these subtypes. METHODS: Four hundred sixty-eight patients admitted for an MI were assessed for the presence of an ICD-10 depressive disorder following MI. A comparison was made between first-ever and ongoing or recurrent depression on demographic and cardiac data, personality, and depression characteristics. RESULTS: Depressive disorder during the first post-MI year was present in 25.4% of the MI patients (n = 119), and almost half were ongoing or recurrent (n = 53, 44.5%). Recurrent and ongoing depression was related to high neuroticism (Z = 2.77, P < .01), whereas first-ever depression was associated with MI severity (poor left ventricular ejection fraction: Z = 1.64, P = .05; PTCA or CABG during hospitalization: Z = 1.88, P = .03; arrhythmic events: Z = 1.49, P = .06). CONCLUSIONS: Our results suggest that in the first-ever post-MI depression cases, depression may be triggered by the severity of the MI, whereas ongoing and recurrent depression is more related to personality. Future research should address the question whether these subtypes of depression differ in cardiovascular prognosis and response to psychiatric treatment.

Predictability of the one-year course of depression and generalized anxiety in primary care.

Several predictors of the course of depression and generalized anxiety have been identified. Whether these predictors provide a solid basis for primary care physicians (PCPs) to give an accurate prognosis remains unclear. A parallel study showed modest agreement between PCP prognosis and observed course (kappa< or = 0.21). It is the aim of the present study to establish the extent to which the one-year course of depression and generalized anxiety in primary care is in fact predictable. Predictability is operationalized as the combined predictive power of major prognostic factors identified in the literature. We identified 269 cases of ICD-10 depression and 134 of generalized anxiety among consecutive PCP attenders. For these patients a statistical model was built that provided optimal predictions of the one-year course of the disorder, based on the prognostic factors discerned. The predictions were compared with the actual course observed. Reasonable agreement (kappa = 0.37 for depression, kappa = 0.35 for anxiety) and good association (gamma = 0.66 for depression, gamma=0.67 for anxiety) were found between predicted and observed course. Nevertheless, the combined predictive power of the prognostic factors remains limited. A realistic evaluation of the accuracy of the PCP prognosis should take this limited predictability into account.

Prognostic association of depression following myocardial infarction with mortality and cardiovascular events: a meta-analysis.

OBJECTIVE: To assess the association of depression following myocardial infarction (MI) and cardiovascular prognosis. METHODS: The authors performed a meta-analysis of references derived from MEDLINE, EMBASE, and PSYCINFO (1975-2003) combined with crossreferencing without language restrictions. The authors selected prospective studies that determined the association of depression with the cardiovascular outcome of MI patients, defined as mortality and cardiovascular events within 2 years from index MI. Depression had to be assessed within 3 months after MI using established psychiatric instruments. A quality assessment was performed. RESULTS: Twenty-two papers met the selection criteria. These studies described follow up (on average, 13.7 months) of 6367 MI patients (16 cohorts). Post-MI depression was significantly associated with all-cause mortality (odds ratio [OR], fixed 2.38; 95% confidence interval [CI], 1.76-3.22; p <.00001) and cardiac mortality (OR fixed, 2.59; 95% CI, 1.77-3.77; p <.00001). Depressive MI patients were also at risk for new cardiovascular events (OR random, 1.95; 95% CI, 1.33-2.85; p = .0006). Secondary analyses showed no significant effects of follow-up duration (0-6 months or longer) or assessment of depression (self-report questionnaire vs. interview). However, the year of data collection (before or after 1992) tended to influence the effect of depression on mortality (p = .08), with stronger associations found in the earlier studies (OR, 3.22; 95% CI, 2.14-4.86) compared with the later studies (OR, 2.01; 95% CI, 1.45-2.78). CONCLUSIONS: Post-MI depression is associated with a 2- to 2.5-fold increased risk of impaired cardiovascular outcome. The association of depression with cardiac mortality or all-cause mortality was more pronounced in the older studies (OR, 3.22 before 1992) than in the more recent studies (OR, 2.01 after 1992).

Depressive symptoms in elderly patients after a somatic illness event: prevalence, persistence, and risk factors.

Elderly patients with somatic illness are at increased risk of depression. The authors studied the prevalence and persistence of depressive symptoms during the first year after the events of myocardial infarction, congestive heart failure, fall-related injury, and the diagnosis of cancer and their putative pre-event risk factors. The GLAS study contains data from 614 patients who experienced post-baseline myocardial infarction, cancer, heart failure, or fall-related injury of the extremities within 5 years after the baseline assessment. Follow-up was conducted 8 weeks, 6 months, and 1 year after the somatic event. The authors studied the relative importance of 21 baseline risk factors for experiencing significant depressive symptoms during follow-up and the persistence of depression. Depressive symptoms were prevalent in 38.3% of the subjects during the post-event year; in about 19.1%, symptoms were mild. For a majority of patients (67.5%), symptoms persisted until the next assessment. Significant pre-event risk factors were depressive symptoms at baseline, age, smoking, poor general health, poor well-being, and neuroticism. Within the depressed group, only neuroticism was related to the persistence of symptoms. Neuroticism increases the risk of experiencing post-event depressive symptoms and is related to their persistence, which suggests the existence of a depression-prone personality.
