Cardiovascular risk factors for people with mental illness

Objective: The objective of this study was to document the prevalence of risk factors for cardiovascular disease among people with chronic mental illness. Method: A cross-sectional survey was conducted of 234 outpatients attending a community mental health clinic in the North-western Health Care Network in Melbourne, Australia. Prevalence of smoking, alcohol consumption, body mass index, hypertension, salt intake, exercise and history of hypercholesterolemia was assessed. Results: Compared with a community sample, the mentally ill had a higher prevalence of smoking, overweight and obesity, lack of moderate exercise, harmful levels of alcohol consumption and salt intake. No differences were found on hypertension. Men, but not women, with mental illness were less likely to undertake cholesterol screening. Conclusions: Psychiatric outpatients have a high prevalence of cardiovascular risk factors which may account for the higher rate of cardiovascular mortality among the mentally ill. Further research is needed to trial and evaluate interventions to effectively modify risk factors in this vulnerable population.

High prevalence disorders in urban and rural communities

Objective: High prevalence disorders (anxiety, depressive and substance use) are generally assumed to be more common in urban than rural dwellers. The aims of this paper are (i) to critically review studies measuring prevalence in rural as opposed to urban location, and (ii) to argue the need to look beyond the ‘quantity’ question to the quality question: how does urban or rural place influence mental health? Method: A literature review (Medline and PsychLIT) was carried out using the words ‘rural, urban, mental/psychiatric, illness/disorders and prevalence’, as well as a review of relevant papers and publications known to the authors. Results: Many studies examining urban/rural differences in the rate of high prevalence disorders have been reported. Most use a ‘one size fits all’ definition of urban and rural, which assumes location is the key issue. The majority fail to show the purported difference in prevalence between the two settings. In general, studies have not examined interaction effects, but have simply treated the independent variables as main effects. Available data suggest that a variety of socio-demographic factors are more powerful predictors of difference in prevalence than is the location of residence. Conclusion: Further studies are required to understand if and how rural or urban place contributes to the development of psychiatric morbidity. These studies should mirror the clinical situation by taking into account a variety of individual and community-based (including urban/rural place) risk factors which may be important determinants of mental health and mental illness, and examining the interaction between them. This may then identify the nature of any differences or what issues are specific to, or especially important, in the rural setting.

Posttraumatic stress disorder in response to HIV infection

This study investigated the psychological impact of HIV infection through assessment of posttraumatic stress disorder in response to HIV infection. Sixty-one HIV-positive homosexual/bisexual men were assessed for posttraumatic stress disorder in response to HIV infection (PTSD-HIV) using a modified PTSD module of the DIS-III-R. Thirty percent met criteria for a syndrome of posttraumatic stress disorder in response to HIV diagnosis (PTSD-HIV). In over one-third of the PTSD cases, the disorder had an onset greater than 6 months after initial HIV infection diagnosis. PTSD-HIV was associated with other psychiatric diagnoses, particularly the development of first episodes of major depression after HIV infection diagnosis. PTSD-HIV was significantly associated with a pre-HIV history of PTSD from other causes, and other pre-HIV psychiatric disorders and neuroticism scores, indicating a similarity with findings in studies of PTSD from other causes. The findings from this preliminary study suggest that a PTSD response to HIV diagnosis has clinical validity and requires further investigation in this population and other medically ill groups. The results support the inclusion of the diagnosis of life-threatening illness as a traumatic incident that may lead to a posttraumatic stress disorder, which is consistent with the DSM-IV criteria.

The influence of stigma and attitudes on seeking help from a GP for mental health problems

Lack of mental health specialists in rural and remote communities suggest that rural communities depend more on general practitioners (GPs) for mental health care. Residents of rural communities are less likely than urban residents to seek help from their GPs for mental health issues. The aim of the current study was to examine whether attitudinal factors including perceived stigma, influenced rural residents seeking help from GPs. Help-seeking for psychological issues was retrospectively reported by 300 community residents in rural north-west Victoria. Current distress levels, functional disability, and current or lifetime syndromal disorder were recorded. Attitudes towards seeking professional psychological help, perceptions of stigma about mental illness, and belief in helpfulness of GPs, were also measured. Having a positive attitude towards seeking professional help, and believing that a GP would be helpful, were significant predictors of ever having sought help from a GP for mental health problems. Other independent predictors of help-seeking included having a mood, anxiety or substance use disorder, higher distress levels, and greater functional disability due to physical problems. Seeking help from a GP for psychological problems was predicted by having a positive attitude towards seeking professional psychological help as well as believing a GP would be helpful in treating psychological problems. Illness variables were also strong predictors of help-seeking behaviour. Contrary to expectations, perceived stigma did not influence help-seeking. The findings of this study highlight the important role of GPs in the treatment of mental health problems in the rural community.

Understanding suicide in Australian farmers

ObjectiveMale farmers in Australia have an elevated risk of suicide. The aims of this study were to investigate the rate of mental health problems amongst farmers compared with non-farmer rural residents and to investigate what additional factors might contribute to an increased risk of suicide amongst farmers.MethodThis study used a combination of quantitative and qualitative approaches. First, using self-report questionnaire data, we compared rates of mental health problems (a common correlate of suicide) and a number of personality measures between farmers (n=371) and non-farming rural residents (n=380). In addition, semi-structured interviews with farmers (n=32) were used to gain a richer understanding of how the context of farming and mental health interact.ResultsFive key findings emerged from the study. First, in the quantitative study, we found no support for the proposition that farmers experience higher rates of mental health problems than do non-farmer rural residents, but we identified potentially important personality differences between farmers and non-farmers, with levels of conscientiousness being significantly higher amongst farmers and levels of neuroticism being significantly lower. A strong association between maleness and farming was also found. In the qualitative study, participants indicated that farming is an environment in which individuals experienced a range of stressors but have limited capacity to acknowledge or express these. In addition, there appeared to be significant attitudinal barriers to seeking help for those who may have mental health problems, particularly male farmers.ConclusionThe elevated rate of suicide amongst farmers does not seem to be simply explained by an elevated rate of mental health problems. Individual personality, gender and community attitudes that limit a persons ability to acknowledge or express mental health problems and seek help for these may be significant risk factors for suicide in farmers.

Depression and neurocognitive performance in individuals with HIV/AIDS: 2-year follow-up

The aims of this study were to follow a cohort of HIV‐infected individuals for 2 years to assess changes in depression and neuropsychological performance over time, to explore the relationship between depression, HIV illness and neuropsychological performance, and to examine the natural history of the effect of highly active antiretroviral therapy (HAART) on depression and neurocognitive performance.

Depressive symptoms reduced in individuals with HIV/AIDS treated with highly active antiretroviral therapy: a longitudinal study

Objective: The aims of this study were to investigate the stability of depressive symptoms over time, explore possible reasons for the genesis of depressive symptoms, examine psychosocial adjustment over time and examine the effects of the introduction of highly active antiretroviral therapy (HAART) in a group of HIV infected patients. Method: HIV seropositive outpatients were assessed at 6 monthly intervals over a 2-year period. At each assessment patients completed the Beck Depression Inventory, the Life Event Inventory, the Core Bereavement Item questionnaire and the Psychosocial Adjustment to Illness Scale. Details regarding HIV illness progression and antiretroviral treatment were recorded for each follow-up assessment. Results: One hundred and sixty-three patients completed the baseline assessment and proceeded to the 2-year follow-up study. Most patients remained well over the 2-year follow-up period; mean CD4 count for the group increased over the study period. Ten patients developed AIDS and 18 patients died. Antiretroviral medications changed significantly during the follow-up, with most patients changing to combination (triple) therapy, which included the use of a protease inhibitor. Psychosocial stressors (life event distress and number of bereavements) reduced as the study progressed. Reported depressive symptoms decreased over time and psychosocial adjustment to illness tended to improve over the 2-year period. Conclusions: Over a 2-year follow-up period HIV/AIDS symptoms and illness markers and psychosocial adjustment to illness improved, psychological stressors and depressive symptoms decreased, with a temporal relationship to changes in antiretroviral therapy.

Depression in People Living with HIV/AIDS Attending Primary Care and Outpatient Clinics

Objective: Our aim was to gain an estimate of the rate of depressive disorder in patients with HIV/AIDS attending general practice and to investigate factors associated with depression. A further objective was to determine the ability of non-mental health medical practitioners to detect depressive symptoms in their patients with HIV/AIDS. Method: Participants comprised 322 persons living with HIV/AIDS ((PLWHA); 13 females, 309 males; mean age 41.4, SD = 8.9) who were recruited from four general practice clinics specializing in HIV medicine and from an infectious diseases clinic. Medical, psychiatric and sociodemographic data were obtained. In addition, participants completed the Inventory to Diagnose Depression (IDD), a self-report measure to detect depression. Results: Twenty-two per cent of the sample met criteria for a current Major Depressive Episode (DSM-IV defined) on the IDD. Overall, there was moderate agreement between treating doctors’ diagnosis of depression and patients’ self-report of depressive symptoms. A multivariate model indicated that being in a current relationship was associated with lowered odds of depression (OR = 0.43; CI = 0.23–0.81). The factors strongly associated with increased odds of depression were a past history of illicit drug use (OR = 2.98; CI = 1.60–5.54) and a diagnosis of ‘stress’ by treating doctors (OR = 5.65; CI = 2.50–12.77). HIV-related medical variables such as immune function, use of antiretroviral medication and duration of HIV infection were not associated with depression. Conclusions: There was a high rate of self-reported depression in this group of PLWHA which was also recognized by treating clinicians. Being in a relationship appeared to afford protection against depression while having a history of illicit drug use and current ‘stress’ were highly associated with depression. Interestingly, HIV-related medical variables including laboratory markers of HIV disease, duration of illness and antiretroviral medication regimen were not related to depression.

Case managers' attitudes to the physical health of their patients.

Objective: To examine the attitudes and practices of case managers working in Area Mental Health Services (AMHS) towards the physical health of people with chronic mental illness. Method: Case managers at four AMHS in Melbourne participated in focus groups and completed a survey questionnaire. Results: Case managers generally believed that mental illness, psychotropic medication and lifestyle factors contributed to the poor physical health status of their patients. Although many case managers attempted interventions aimed at improving physical health, there was inconsistency regarding the areas targeted. Preventive health measures were often neglected. Overall, there was a sense of pessimism around whether improved physical health was possible for people with chronic mental illness. Conclusions: Lack of coordination among health professionals and the health system may contribute to the poor general health of people with mental illness. Patients often have difficulty accessing general practitioners and the culture within the AMHS can exclude considerations of physical health. Case management should include aspects addressing the physical health issues of AMHS clients.

Secondary mania in patients with HIV infection

Objective: The aim of this study was to identify a cohort of patients with mania secondary to HIV infection, to describe the clinical and radiological features of HIV-related mania, and to describe the treatment outcome of the patients. Method: All patients referred to the HIV consultation-liaison psychiatry service over the 29-month period from January 1993 to June 1995 were screened for the presence of manic symptoms. Diagnosis of mania was made according to DSM-III-R. Cases were defined as secondary mania if there was no clear history of mood disorder, and no family history of mood disorder. Cases were interviewed by the treating psychiatry registrar and psychiatrist to obtain information regarding present and past psychiatric history and family history of psychiatric disorder. The psychiatry registrar and consultant determined treatment. Results: Twenty-three patients with mania were identified; 19 were considered to have secondary mania. The prevalence of secondary mania over the 29 months was 1.2% for HIV-positive patients, and 4.3% for those with AIDS. The clinical characteristics and response to treatment appeared to be similar to mania associated with bipolar affective disorder (primary mania). Neuroradiological abnormalities were common, occurring in 10 of the 19 patients, but did not appear to be clinically relevant. Cognitive impairment developed in five of the 15 patients where follow-up was possible. Conclusions: Mania occurring in advanced HIV disease appears to be more common than expected from epidemiological data regarding bipolar affective disorder. Differentiating secondary from primary mania has implications for the management and prognosis of mania.
