Increases in youth mental health services in Australia: Have they had an impact on youth population mental health?

BACKGROUND: Mental disorders often have their first onset during youth, which justifies targeting treatment services at this age group. Australia has had a substantial increase in youth mental health services since the introduction of the Medicare Better Access scheme and headspace services in 2006-2007. This paper examines trends in the mental health of Australian youth before and after this time using available national and state datasets. METHODS: The following data were examined for age groups available in the age range of 12-25 years: use of mental health services per 100,000 population provided under Medicare by GPs, psychiatrists, clinical psychologists, other psychologists and allied health professionals; per capita accessing of headspace services; and prevalence of high and very high psychological distress (using the K10) in youth age groups in the National Health Survey, the Victorian Population Health Survey and the New South Wales Population Health Survey between 2001 and 2018. RESULTS: There has been a large increase in use of mental health services since the introduction of Better Access and headspace. No significant improvement in youth mental health was evident following the introduction of these schemes. Rather, there appeared to be a worsening of youth mental health from around 2015 onwards. CONCLUSION: Despite a large increase in the provision of mental health services to Australian youth, there has not been a detectable reduction in the prevalence of psychological distress. There may be other factors that have worsened youth mental health in recent years.

What works for mental health problems in youth? Survey of real-world experiences of treatments and side effects.

AIM: Despite youth being the most common age group for onset of mental disorders, there is less knowledge on the benefits and harms of treatments in young people. In addition, efficacy data from randomized controlled trials may not generalize to how treatment works outside of research settings. This study aimed to investigate young people's perceived effectiveness of different treatments for mental health problems, the professionals who delivered these, and the experience of negative effects. METHODS: We developed a consumer report website where young people who were ever diagnosed with a mental disorder provided ratings on the helpfulness or harmfulness of different types of professionals, mental health treatments (medical, psychological complementary/alternative) and self-help strategies, and whether they had experienced particular negative effects. RESULTS: Here, 557 young people aged 12-25 years, who were recruited from English-speaking, high-income countries, provided 1258 ratings of treatments. All treatments showed varied perceptions of effectiveness. Medical and psychological treatments were rated moderately helpful on average with low rates of harmfulness. Self-help strategies were rated as being as helpful as professional treatments. Side effects related to the head or mind (e.g., concentration difficulties, inability to feel emotions, depression and irritability) were the most common across all types of medicines. For psychological treatments, treatment being too expensive and feeling worse at the end of a session were the most commonly reported negative effects. CONCLUSIONS: Study findings may be a useful guide to clinicians, researchers, young people and their families about what is likely to work in real-world settings.

High prevalence of health and social risk behaviours among men experiencing suicidal thoughts and behaviour: The imperative to undertake holistic assessments.

OBJECTIVE: We aimed to examine whether suicidal thoughts and behaviour were independently associated with a wide range of health and social risk behaviours. METHODS: We conducted cross-sectional analyses of data collected from 13,763 adult males who participated in The Australian Longitudinal Study on Male Health. We fit generalised linear models to estimate the relative risk of engaging in a range of health and social risk behaviours across several domains by suicidal thoughts and behaviour status. RESULTS: Men with recent suicidal ideation (relative risk range, 1.10-5.25) and lifetime suicide attempts (relative risk range, 1.10-7.65) had a higher risk of engaging in a broad range of health and social risk behaviours. The associations between suicidal thoughts and behaviour and health and social risk behaviours were typically independent of socio-demographics and in many cases were also independent of depressive symptoms. CONCLUSION: Suicidal thoughts and behaviour overlaps with increased risk of engagement in a wide range of health and social risk behaviours, indicating the need for an alignment of broader public health interventions within clinical and community-based suicide prevention activities. The experience of suicidality may be an important catalyst for a broader psychosocial conversation and assessment of health and social risk behaviours, some of which may be modifiable. These behaviours may not carry an imminent risk of premature death, such as from suicide, but they carry profound health and social consequences if left unaddressed.

A school-based health promotion programme to increase help-seeking for substance use and mental health problems: study protocol for a randomised controlled trial.

BACKGROUND: Adolescence is a high-risk time for the development of mental health and substance use problems. However, fewer than one in four 16-24 year-olds with a current disorder access health services, with those experiencing a substance use disorder being the least likely to seek professional help. Research indicates that young people are keeping their problems to themselves or alternatively, turning to peers or trusted adults in their lives for help. These help-seeking preferences highlight the need to build the mental health literacy of adolescents, to ensure that they know when and how to assist themselves and their peers to access support. The MAKINGtheLINK intervention aims to introduce these skills to adolescents within a classroom environment. METHODS/DESIGN: This is a cluster randomised controlled trial (RCT) with schools as clusters and individual students as participants from 22 secondary schools in Victoria, Australia. Schools will be randomly assigned to either the MAKINGtheLINK intervention group or the waitlist control group. All students will complete a self-report questionnaire at baseline, immediately post intervention and 6 and 12 months post baseline. The primary outcome to be assessed is increased help-seeking behaviour (from both formal and informal sources) for alcohol and mental health issues, measured at 12 months post baseline. DISCUSSION: The findings from this research will provide evidence on the effectiveness of the MAKINGtheLINK intervention for teaching school students how to overcome prominent barriers associated with seeking help, as well as how to effectively support their peers. If deemed effective, the MAKINGtheLINK programme will be the first evidence-informed resource that is able to address critical gaps in the knowledge and behaviour of adolescents in relation to help-seeking. It could, therefore, be a valuable resource that could be readily implemented by classroom teachers.

Self-help strategies for sub-threshold anxiety: A Delphi consensus study to find messages suitable for population-wide promotion.

BACKGROUND: Many self-help strategies have been recommended for anxiety, but it is not clear which strategies are most effective and could be encouraged as part of an early intervention approach. This study used the Delphi expert consensus method to identify which strategies for mild (sub-threshold) anxiety are thought to be helpful and feasible to implement for individuals without professional assistance. METHODS: Participants were an international sample of 51 clinicians/researchers and 32 consumer advocates with expertise in anxiety. The scientific and lay literature was systematically searched for strategies claimed to be effective for anxiety. Participants rated the likely helpfulness of each strategy in reducing sub-threshold anxiety (related to generalised anxiety, social anxiety, or non-specific anxiety symptoms) and the feasibility of implementation in an iterative process across three questionnaire rounds. RESULTS: 66 out of 324 candidate strategies were endorsed by at least 80% of both consumers and clinicians/researchers as likely to be helpful, and 18 were judged as feasible to carry out. Endorsed strategies were most frequently related to cognitive strategies and other psychological methods, interpersonal strategies, reducing physical tension, and lifestyle strategies. Few strategies were endorsed that were related to diet, supplements, or complementary medicine. LIMITATIONS: Findings may not apply to other forms of mild anxiety related to panic attacks or specific phobias. CONCLUSIONS: This study contributes to the evidence-base on strategies that individuals can use to improve mild anxiety symptoms. Research is now required to evaluate whether promoting the strategies can help reduce the overall community burden from anxiety disorders.

Depression literacy of undergraduates in a non-western developing context: the case of Sri Lanka.

BACKGROUND: Research examining the depression literacy of undergraduates in non-western developing countries is limited. This study explores this among undergraduates in Sri Lanka. METHODS: A total of 4671 undergraduates responded to a survey presenting a vignette of a depressed undergraduate. They were asked to identify the problem, describe their intended help-seeking actions if affected by it and rate the helpfulness of a range of help-providers and interventions for dealing with it. Mental health experts also rated these options, providing a benchmark for assessing the undergraduates' responses. RESULTS: Only 17.4% of undergraduates recognised depression, but this was significantly lower among those responding in Sinhala compared to English (3.5 vs 36.8%). More undergraduates indicated intentions of seeking informal help, such as from friends and parents, than from professionals, such as psychiatrists and counsellors. However, a majority rated all these help-providers as 'helpful', aligning with expert opinion. Other options recommended by experts and rated as 'helpful' by a large proportion of undergraduates included counselling/psychological therapy and self-help strategies such as doing enjoyable activities and meditation/yoga/relaxation exercises. However, a low proportion of undergraduates rated "western medicine to improve mood" as 'helpful', deviating from expert opinion. Although not endorsed by experts, undergraduates indicated intentions of using religious strategies, highly endorsing these as 'helpful'. Labelling the problem as depression and using mental health-related labels were both associated with higher odds of endorsing professional help, with the label 'depression' associated with endorsing a wider range of professional options. CONCLUSIONS: The recognition rate of depression might be associated with the language used to label it. These undergraduates' knowledge about the use of medication for depression needs improvement. Health promotion interventions for depressed undergraduates must be designed in light of the prevalent socio-cultural backdrop, such as the undergraduates' high endorsement of informal and culturally relevant help-seeking. Improving their ability to recognise the problem as being mental health-related might trigger their use of professional options of help.

Oral folic acid and vitamin B-12 supplementation to prevent cognitive decline in community-dwelling older adults with depressive symptoms--the Beyond Ageing Project: a randomized controlled trial.

BACKGROUND: Evidence remains unclear as to whether folic acid (FA) and vitamin B-12 supplementation is effective in reducing depressive symptoms. OBJECTIVES: The objective was to determine whether oral FA + vitamin B-12 supplementation prevented cognitive decline in a cohort of community-dwelling older adults with elevated psychological distress. DESIGN: A randomized controlled trial (RCT) with a completely crossed 2 × 2 × 2 factorial design comprising daily oral 400 µg FA + 100 µg vitamin B-12 supplementation (compared with placebo), physical activity promotion, and depression literacy with comparator control interventions for reducing depressive symptoms was conducted in 900 adults aged 60-74 y with elevated psychological distress (Kessler Distress 10-Scale; scores >15). The 2-y intervention was delivered in 10 modules via mail with concurrent telephone tracking calls. Main outcome measures examined change in cognitive functioning at 12 and 24 mo by using the Telephone Interview for Cognitive Status-Modified (TICS-M) and the Brief Test of Adult Cognition by Telephone (processing speed); the Informant Questionnaire on Cognitive Decline in the Elderly was administered at 24 mo. RESULTS: FA + vitamin B-12 improved the TICS-M total (P = 0.032; effect size d = 0.17), TICS-M immediate (P = 0.046; d = 0.15), and TICS-M delayed recall (P = 0.013; effect size d = 0.18) scores at 24 mo in comparison with placebo. No significant changes were evident in orientation, attention, semantic memory, processing speed, or informant reports. CONCLUSION: Long-term supplementation of daily oral 400 µg FA + 100 µg vitamin B-12 promotes improvement in cognitive functioning after 24 mo, particularly in immediate and delayed memory performance. This trial was registered at clinicaltrials.gov as NCT00214682.

Mental health literacy, folic acid and vitamin B12, and physical activity for the prevention of depression in older adults: randomised controlled trial.

BACKGROUND: Few randomised controlled trials (RCTs) have examined potential preventive agents in high-risk community populations. AIMS: To determine whether a mental health literacy intervention, the promotion of physical activity, or folic acid plus vitamin B(12) reduce depression symptoms in community-dwelling older adults with elevated psychological distress. METHOD: An RCT with a completely crossed 2 x 2 x 2 factorial design: (400 mcg/d folic acid + 100 mcg/d vitamin B(12) v. placebo)x(physical activity v. nutrition promotion control)x(mental health literacy v. pain information control). The initial target sample size was 2000; however, only 909 adults (60-74 years) met the study criteria. Interventions were delivered by mail with telephone calls. The main outcome was depressive symptoms on the Patient Health Questionnaire (PHQ-9) at 6 weeks, 6, 12 and 24 months. The Clinicaltrials.gov registration number is NCT00214682. RESULTS: The drop-out rate was low (13.5%) from randomisation to 24-month assessment. Neither folic acid + B(12) (F(3,856) = 0.83, P = 0.476) nor physical activity (F(3,856) = 1.65, P = 0.177) reduced depressive symptoms at any time point. At 6 weeks, depressive symptoms were lower for the mental health literacy intervention compared with its control condition (t(895) = 2.04, P = 0.042). CONCLUSIONS: Mental health literacy had a transient effect on depressive symptoms. Other than this, none of the interventions significantly reduced symptoms relative to their comparator at 6 weeks or subsequently. Neither folic acid plus B(12) nor physical activity were effective in reducing depressive symptoms.

Community beliefs about causes and risks for mental disorders: a mental health literacy survey in a rural area of Maharashtra, India.

BACKGROUND: Explanations for mental disorders in India can be influenced by biomedicine, systems of traditional medicine and supernatural beliefs. Community beliefs about causes of mental distress influence help-seeking behaviours. This study aimed to assess local knowledge and understanding of causes and risks for mental disorders in a rural area of Maharashtra, and to assess the prevalence of possible common mental disorders. METHODS: A cross-sectional mental health literacy survey was undertaken in late 2007. A questionnaire was administered to 240 systematically sampled community members and 60 village health workers (VHWs). Participants were presented with two vignettes describing people experiencing symptoms of mental disorders (depression, psychosis); they were asked about the causes of the problems and the vulnerabilities of community sub-groups. Additionally, the General Health Questionnaire (GHQ12) was administered to assess prevalence of possible common mental disorders. RESULTS: The most commonly acknowledged causes of the problems were a range of socioeconomic factors. Supernatural and biological explanations were not widely endorsed. Women, the unemployed and the poor were judged as more likely to develop mental disorders, while both young and older people were perceived to be less vulnerable. Results of the GHQ12 indicated that 27% had a possible common mental disorder and that the elderly were at increased risk, contrary to community perceptions. CONCLUSION: Enhancing mental health literacy of both VHWs and community members using approaches that are sensitive to local conceptualizations of mental health and illness will contribute to improved treatment and care for people with mental disorders. Further investigation of mental health among the elderly in this community is indicated.

Outcomes of self-help efforts in anxiety disorders.

Anxiety disorders are prevalent mental disorders that are a significant burden on the community. There are effective treatments available, but many people do not seek treatment and there is a lack of professionals available to provide evidence-based treatment to all those with anxiety disorders. Recently, there has been increased attention on ways to cost effectively meet the demand for treatment with minimal cost to health services. Self-help efforts have been proposed to play a role, either as an initial minimal treatment in stepped-care models of treatment, or as strategies undertaken by an individual to prevent a full disorder developing. This review examines what is known from randomized controlled trials about the efficacy of self-help interventions for anxiety disorders.

Relaxation for depression.

BACKGROUND: Many members of the public have negative attitudes towards antidepressants. Psychological interventions are more acceptable but require considerable therapist training. Acceptable psychological interventions that require less training and skill are needed to ensure increased uptake of intervention. A potential intervention of this sort is relaxation techniques. OBJECTIVES: To determine whether relaxation techniques reduce depressive symptoms and improve response/remission. SEARCH STRATEGY: The register of trials kept by the Cochrane Collaboration Depression, Anxiety and Neurosis Group was searched up to February 2008. We also searched the reference lists of included studies. SELECTION CRITERIA: Studies were included if they were randomised or quasi-randomised controlled trials of relaxation techniques (progressive muscle relaxation, relaxation imagery, autogenic training) in participants diagnosed with depression or having a high level of depression symptoms. Self-rated and clinician-rated depression scores and response/remission were the primary outcomes. DATA COLLECTION AND ANALYSIS: Two reviewers selected the trials, assessed the quality and extracted trial and outcome data, with discrepancies resolved by consultation with a third. Trial authors were approached for missing data where possible and missing data were estimated or imputed in some cases. Continuous measures were summarised using standardised mean differences and dichotomous outcomes by risk ratios. MAIN RESULTS: There were 15 trials with 11 included in the meta-analysis. Five trials showed relaxation reduced self-reported depression compared to wait-list, no treatment, or minimal treatment post intervention (SMD -0.59 (95% CI -0.94 to -0.24)). For clinician-rated depression, two trials showed a non-significant difference in the same direction (SMD -1.35 (95% CI -3.06 to 0.37)).Nine trials showed relaxation produced less effect than psychological (mainly cognitive-behavioural) treatment on self-reported depression (SMD = 0.38 (95% CI 0.14 to 0.62)). Three trials showed no significant difference between relaxation and psychological treatment on clinician-rated depression at post intervention (SMD 0.29 (95% CI -0.18 to 0.75)).Inconsistent effects were found when comparing relaxation training to medication and there were few data available comparing relaxation with complementary and lifestyle treatments. AUTHORS' CONCLUSIONS: Relaxation techniques were more effective at reducing self-rated depressive symptoms than no or minimal treatment. However, they were not as effective as psychological treatment. Data on clinician-rated depressive symptoms were less conclusive. Further research is required to investigate the possibility of relaxation being used as a first-line treatment in a stepped care approach to managing depression, especially in younger populations and populations with subthreshold or first episodes of depression.

Self-help interventions for depressive disorders and depressive symptoms: a systematic review.

BACKGROUND: Research suggests that depressive disorders exist on a continuum, with subthreshold symptoms causing considerable population burden and increasing individual risk of developing major depressive disorder. An alternative strategy to professional treatment of subthreshold depression is population promotion of effective self-help interventions that can be easily applied by an individual without professional guidance. The evidence for self-help interventions for depressive symptoms is reviewed in the present work, with the aim of identifying promising interventions that could inform future health promotion campaigns or stimulate further research. METHODS: A literature search for randomised controlled trials investigating self-help interventions for depressive disorders or depressive symptoms was performed using PubMed, PsycINFO and the Cochrane Database of Systematic Reviews. Reference lists and citations of included studies were also checked. Studies were grouped into those involving participants with depressive disorders or a high level of depressive symptoms, or non-clinically depressed participants not selected for depression. A number of exclusion criteria were applied, including trials with small sample sizes and where the intervention was adjunctive to antidepressants or psychotherapy. RESULTS: The majority of interventions searched had no relevant evidence to review. Of the 38 interventions reviewed, the ones with the best evidence of efficacy in depressive disorders were S-adenosylmethionine, St John's wort, bibliotherapy, computerised interventions, distraction, relaxation training, exercise, pleasant activities, sleep deprivation, and light therapy. A number of other interventions showed promise but had received less research attention. Research in non-clinical samples indicated immediate beneficial effects on depressed mood for distraction, exercise, humour, music, negative air ionisation, and singing; while potential for helpful longer-term effects was found for autogenic training, light therapy, omega 3 fatty acids, pets, and prayer. Many of the trials were poor quality and may not generalize to self-help without professional guidance. CONCLUSION: A number of self-help interventions have promising evidence for reducing subthreshold depressive symptoms. Other forms of evidence such as expert consensus may be more appropriate for interventions that are not feasible to evaluate in randomised controlled trials. There needs to be evaluation of whether promotion to the public of effective self-help strategies for subthreshold depressive symptoms could delay or prevent onset of depressive illness, reduce functional impairment, and prevent progression to other undesirable outcomes such as harmful use of substances.

Effectiveness of complementary and self-help treatments for anxiety in children and adolescents.

OBJECTIVE: To review the evidence for the effectiveness of complementary and self-help treatments for anxiety disorders and situational anxiety in children and adolescents. DATA SOURCES: Systematic literature search using PubMed, PsycINFO and the Cochrane Library for 111 treatments up to February 2006. STUDY SELECTION: There were 11 treatments for which intervention studies had been undertaken and reported. DATA EXTRACTION: Studies on each treatment were reviewed by one author and checked by a second. A consensus was reached for level of evidence. DATA SYNTHESIS: Relevant evidence was available for bibliotherapy, dance and movement therapy, distraction techniques, humour, massage, melatonin, relaxation training, autogenic training, avoiding marijuana, a mineral-vitamin supplement (EMPower +) and music therapy. Findings from case-control studies, individual cohort studies or low quality randomised controlled trials indicated that several treatments may have potential to reduce anxiety, including bibliotherapy, massage, melatonin, and relaxation training. CONCLUSIONS: Although some complementary and self-help treatments might be useful for children and adolescents with anxiety, they need to be tested adequately through randomised controlled trials before they could be recommended.

What's in a name? Is accurate recognition and labelling of mental disorders by young people associated with better help-seeking and treatment preferences?

BACKGROUND: The possible benefits or harms of using psychiatric labels in the community have been a focus of debate for many decades. The aim of this study was to examine associations between the accuracy of labelling of depression or psychosis by young people aged 12-25 and their help-seeking, treatment and self-help preferences, whilst controlling for a range of potential confounding factors. METHODS: A randomly selected population sample of 1,207 young people aged 12-25 years from several regions of Victoria, Australia, was interviewed via a telephone survey. The structured interviews used vignettes of a young person with either depression or psychosis followed by a series of questions related to recognition of disorder and recommended forms of help and treatment. Multiple logistic regression analyses were used to measure the association between a range of help-seeking, treatment and self-help preferences and the predictor variables of accuracy of recognition, socio-demographic background and exposure to mental health problems. RESULTS: Correct labelling of the disorder was the predictor variable most frequently associated with choice of appropriate help and treatment for both the depression and psychosis vignettes. In regard to self-help preferences, correct labelling of the depression vignette was only associated with being less likely to recommend smoking marijuana to relax. Correct labelling of the psychosis vignette, or labelling it as depression, was associated with being less likely to recommend dealing with the problem alone. CONCLUSION: These findings support the view that improving the use of psychiatric labels by young people is beneficial, because it facilitates appropriate help-seeking and treatment choice. The label may be the cue to activating a schema about appropriate action to take.

Effectiveness of complementary and self-help treatments for depression in children and adolescents.

OBJECTIVE: To review the evidence for the effectiveness of complementary and self-help treatments for depression in children and adolescents. DATA SOURCES: Systematic literature search using PubMed, PsycINFO and the Cochrane Library for 131 treatments up to February 2006. STUDY SELECTION: There were 13 treatments that had been evaluated in intervention studies. DATA EXTRACTION: Studies on each treatment were reviewed by one author and checked by a second. A consensus was reached for level of evidence. DATA SYNTHESIS: Relevant evidence was available for glutamine, S-adenosylmethionine, St John's wort, vitamin C, omega-3 fatty acids, light therapy, massage, art therapy, bibliotherapy, distraction techniques, exercise, relaxation therapy and sleep deprivation. However, the evidence was limited and generally of poor quality. The only treatment with reasonable supporting evidence was light therapy for winter depression. CONCLUSIONS: Given that antidepressant medication is not recommended as a first line treatment for children and adolescents with mild to moderate depression, and that the effects of psychological treatments are modest, there is a pressing need to extend the range of treatments available for this age group.

Use of prescription medications and complementary and alternative medicines to treat depressive and anxiety symptoms: results from a community sample.

BACKGROUND: Individuals prescribed antidepressants or anxiolytics may replace or augment such medications with complementary and alternative medicines (CAMs). Little is known about the extent to which individuals in the community use CAMs instead of, or in addition to, medications they have been prescribed, for anxiety and depressive symptoms. METHOD: Information on use of CAMs, antidepressants and anxiolytics was obtained from a community sample of 7485 survey participants from Canberra and environs, Australia. Participants aged 20-24, 40-44, or 60-64 were also provided information on sociodemographic attributes, physical and mental health. RESULTS: 6.29% of participants used only prescription medications to treat their depression or anxiety. 2.28% used only CAMs for this purpose while a further 0.59% reported using both types of treatments. Those using CAMs and those who took prescription medications had comparable levels of mental health problems while CAM users had fewer physical health problems and lower neuroticism. Compared with those taking neither CAMs nor prescribed medication, however, CAM users had more depressive and anxiety symptoms, worse mental health, higher neuroticism and lower levels of mastery. LIMITATIONS: Information on use of prescribed and CAMs is self-reported and is subject to the inaccuracies and omissions associated with this method of data collection. CONCLUSION: We found survey participants used CAMs less frequently than prescription medications to treat their depressive or anxiety symptoms. Nonetheless, medical practitioners should be aware that their patients may use CAMs and seek information about such use to reduce the likelihood of adverse interactions between prescribed medication and CAMs.

Effectiveness of complementary and self-help treatments for anxiety disorders.

OBJECTIVES: To review the evidence for the effectiveness of complementary and self-help treatments for anxiety disorders. DATA SOURCES: Systematic literature search using PubMed, PsycLit, and the Cochrane Library. DATA SYNTHESIS: 108 treatments were identified and grouped under the categories of medicines and homoeopathic remedies, physical treatments, lifestyle, and dietary changes. We give a description of the 34 treatments (for which evidence was found in the literature searched), the rationale behind the treatments, a review of studies on effectiveness, and the level of evidence for the effectiveness studies. CONCLUSIONS: The treatments with the best evidence of effectiveness are kava (for generalised anxiety), exercise (for generalised anxiety), relaxation training (for generalised anxiety, panic disorder, dental phobia and test anxiety) and bibliotherapy (for specific phobias). There is more limited evidence to support the effectiveness of acupuncture, music, autogenic training and meditation for generalised anxiety; for inositol in the treatment of panic disorder and obsessive-compulsive disorder; and for alcohol avoidance by people with alcohol-use disorders to reduce a range of anxiety disorders.

Use of medications to enhance memory in a large community sample of 60-64 year olds.

BACKGROUND: There are no existing epidemiological data on use of medications to enhance memory. METHOD: A community survey was carried out in Canberra and Queanbeyan, Australia, of an electoral roll sample of 2551 adults aged 60-64 years. Data collected included self-reports of using medications to enhance memory, tests of memory and other cognitive functions, anxiety, depression, physical health and use of other medications. RESULTS: 2.8% of the sample reported using medications to enhance memory, the main ones being gingko biloba, vitamin E, bacopa (brahmi), and folic acid/B vitamins. Users were more likely to be female, to have subjective memory problems and to use other psychotropic medications. However, they did not differ in memory performance, anxiety, depression or physical health. DISCUSSION: Some older people are using complementary medications to improve their memory or prevent memory loss, despite the lack of strong evidence for their effectiveness. These people show no objective evidence of memory impairment.

Association of obesity with anxiety, depression and emotional well-being: a community survey.

OBJECTIVE: To investigate the association of obesity with anxiety, depression and emotional well-being (positive and negative affect) in three age groups. METHODS: A cross-sectional survey was carried out in Canberra and the neighbouring town of Queanbeyan, Australia, with a random sample from the electoral roll of 2,280 persons aged 20-24, 2,334 aged 40-44, and 2,305 aged 60-64. RESULTS: Self-reported height and weight were used to classify participants as underweight (body mass index of less than 18.5), acceptable weight (18.5 to less than 25), overweight (25 to less than 30) or obese (30 and over). Obesity in women was associated with more anxiety and depression symptoms and less positive affect, but there were only weak and inconsistent associations in men. When factors that might mediate any association were controlled (physical ill health, lack of physical activity, poorer social support, less education and financial problems), a different picture emerged, with the underweight women having more depression and negative affect and the obese and overweight women tending to have better mental health than the acceptable weight group. Controlling for physical ill health alone accounted for the association of obesity with anxiety and depression in women. CONCLUSIONS: Obesity has an association with anxiety, depression and lower well-being in women, but not in men. The results are consistent with physical ill health playing a mediating role. IMPLICATION: Reducing obesity in the population is unlikely to have any direct effect on mental health or emotional well-being.

Effectiveness of complementary and self-help treatments for depression.

OBJECTIVES: To review the evidence for the effectiveness of complementary and self-help treatments for depression. DATA SOURCES: Systematic literature search using PubMed, PsycLit, the Cochrane Library and previous review papers. DATA SYNTHESIS: Thirty-seven treatments were identified and grouped under the categories of medicines, physical treatments, lifestyle, and dietary changes. We give a description of each treatment, the rationale behind the treatment, a review of studies on effectiveness, and the level of evidence for the effectiveness studies. RESULTS: The treatments with the best evidence of effectiveness are St John's wort, exercise, bibliotherapy involving cognitive behaviour therapy and light therapy (for winter depression). There is some limited evidence to support the effectiveness of acupuncture, light therapy (for non-seasonal depression), massage therapy, negative air ionisation (for winter depression), relaxation therapy, S-adenosylmethionine, folate and yoga breathing exercises. CONCLUSION: Although none of the treatments reviewed is as well supported by evidence as standard treatments such as antidepressants and cognitive behaviour therapy, many warrant further research.
