Abstract: BACKGROUND: Lesbian, gay and bisexual (LGB) people may be at higher risk of mental disorders than heterosexual people. METHOD: We conducted a systematic review and meta-analysis of the prevalence of mental disorder, substance misuse, suicide, suicidal ideation and deliberate self harm in LGB people. We searched Medline, Embase, PsycInfo, Cinahl, the Cochrane Library Database, the Web of Knowledge, the Applied Social Sciences Index and Abstracts, the International Bibliography of the Social Sciences, Sociological Abstracts, the Campbell Collaboration and grey literature databases for articles published January 1966 to April 2005. We also used Google and Google Scholar and contacted authors where necessary. We searched all terms related to homosexual, lesbian and bisexual people and all terms related to mental disorders, suicide, and deliberate self harm. We included papers on population based studies which contained concurrent heterosexual comparison groups and valid definition of sexual orientation and mental health outcomes. RESULTS: Of 13706 papers identified, 476 were initially selected and 28 (25 studies) met inclusion criteria. Only one study met all our four quality criteria and seven met three of these criteria. Data was extracted on 214,344 heterosexual and 11,971 non heterosexual people. Meta-analyses revealed a two fold excess in suicide attempts in lesbian, gay and bisexual people [pooled risk ratio for lifetime risk 2.47 (CI 1.87, 3.28)]. The risk for depression and anxiety disorders (over a period of 12 months or a lifetime) on meta-analyses were at least 1.5 times higher in lesbian, gay and bisexual people (RR range 1.54-2.58) and alcohol and other substance dependence over 12 months was also 1.5 times higher (RR range 1.51-4.00). Results were similar in both sexes but meta analyses revealed that lesbian and bisexual women were particularly at risk of substance dependence (alcohol 12 months: RR 4.00, CI 2.85, 5.61; drug dependence: RR 3.50, CI 1.87, 6.53; any substance use disorder RR 3.42, CI 1.97-5.92), while lifetime prevalence of suicide attempt was especially high in gay and bisexual men (RR 4.28, CI 2.32, 7.88). CONCLUSION: LGB people are at higher risk of mental disorder, suicidal ideation, substance misuse, and deliberate self harm than heterosexual people.

Abstract: BACKGROUND: Research has repeatedly shown that family physicians fail to diagnose up to 70% of patients with common mental disorders. Objective of the study is to investigate associations between persons' gender, age and educational level and detection of depression and anxiety by their family physicians. METHODS: We compared the results of two independent observational studies that were performed at the same time on a representative sample of family medicine practice attendees in Slovenia. 10710 patients participated in Slovenian Cross-sectional survey and 1118 patients participated in a first round of a cohort study (PREDICT-D study). Logistic regression was used to examine the effects of age, gender and educational level on detection of depression and anxiety. RESULTS: The prevalence of major depression and Other Anxiety Syndrome (OAS) amongst family practice attendees was low. The prevalence of Panic Syndrome (PS) was comparable to rates reported in the literature. A statistical model with merged data from both studies showed that it was over 15 times more likely for patients with ICD-10 criteria depression to be detected in PREDICT-D study as in SCS survey. In PREDICT-D study it was more likely for people with higher education to be diagnosed with ICD-10 criteria depression than in SCS survey. CONCLUSION: People with higher levels of education should probably be interviewed in a more standardized way to be recognised as having depression by Slovenian family physicians. This finding requires further validation.

Abstract: AIMS: To determine the risk of coronary heart disease (CHD), acute myocardial infarction (MI), and CHD-related mortality in patients with panic attacks/disorder. METHODS AND RESULTS: We conducted a cohort study using 650 practices in the 'General Practice Research Database'. We selected all 57 615 adults diagnosed with panic attacks/disorder and a random sample of 347 039 unexposed, frequency matched for sex/age, and measured incidence of CHD, MI, and CHD-related mortality rate. There was a significantly higher incidence of MI following new onset panic in people under 50 years of age, but not in older age groups. There was a higher incidence of CHD for all ages, more marked in those under 50 years, but no significant differences in CHD mortality. Fully adjusted models showed panic attacks/disorder were associated with a significantly increased hazard of MI in those under 50 years (HR 1.38, 95% CI 1.06-1.79) and CHD at all ages (<50 years, HR 1.44, 95% CI 1.25-1.65; > or =50 years, HR 1.11, 95% CI 1.03-1.20), but no increased hazard of MI over 50 years (HR 0.92, 95% CI 0.82-1.03), and a slightly reduced CHD-mortality at all ages (HR 0.76, 95% CI 0.66-0.88). CONCLUSION: New onset panic attacks/disorder were associated with increased hazard of subsequent CHD/MI diagnosis in younger people, but with less effect in people over 50, and a slightly reduced hazard of CHD-related mortality. This may be due to initial misdiagnosis of CHD as panic attacks or an underlying increased risk of CHD with panic attacks/disorder in younger people.

Abstract: BACKGROUND: There is evidence that the prevalence of common mental disorders varies across Europe. AIMS: To compare prevalence of common mental disorders in general practice attendees in six European countries. METHOD: Unselected attendees to general practices in the UK, Spain, Portugal, Slovenia, Estonia and The Netherlands were assessed for major depression, panic syndrome and other anxiety syndrome. Prevalence of DSM-IV major depression, other anxiety syndrome and panic syndrome was compared between the UK and other countries after taking account of differences in demographic factors and practice consultation rates. RESULTS: Prevalence was estimated in 2,344 men and 4,865 women. The highest prevalence for all disorders occurred in the UK and Spain, and lowest in Slovenia and The Netherlands. Men aged 30-50 and women aged 18-30 had the highest prevalence of major depression; men aged 40-60 had the highest prevalence of anxiety, and men and women aged 40-50 had the highest prevalence of panic syndrome. Demographic factors accounted for the variance between the UK and Spain but otherwise had little impact on the significance of observed country differences. CONCLUSIONS: These results add to the evidence for real differences between European countries in prevalence of psychological disorders and show that the burden of care on general practitioners varies markedly between countries.

Abstract: The aim of this study was to assess the prevalence of symptoms of panic disorder in a representative community sample of people with dizziness and to compare the profile of those whose panic was consistently linked to attacks of dizziness with those in whom dizziness was just one of many, variable somatic symptoms of panic. Validated questionnaires assessing physical and psychological symptoms, occupational disability, and handicap were administered to 128 people reporting dizziness in an epidemiological survey. Nearly two thirds of the sample reported having panic attacks, and one in four met key criteria for panic disorder. People whose panic symptoms were consistently associated with dizziness reported higher rates of vertigo than those with panic unrelated to dizziness, and higher rates of fainting, agoraphobic behavior, and occupational disability than either comparison group. Explanation of perceptual-motor triggers for disorientation may increase the predictability of attacks, thus reducing vulnerability to dizziness-provoked panic.
