Elucidating knowledge and beliefs about obesity and eating disorders among key stakeholders: paving the way for an integrated approach to health promotion.

BACKGROUND: Understanding the knowledge and beliefs of key stakeholders is crucial in developing effective public health interventions. Knowledge and beliefs about obesity and eating disorders (EDs) have rarely been considered, despite increasing awareness of the need for integrated health promotion programs. We investigated key aspects of knowledge and beliefs about obesity and EDs among key stakeholders in Australia. METHODS: Using a semi-structured question guide, eight focus groups and seven individual interviews were conducted with 62 participants including health professionals, personal trainers, teachers and consumer group representatives. An inductive thematic approach was used for data analysis. RESULTS: The findings suggest that, relative to obesity, EDs are poorly understood among teachers, personal trainers, and certain health professionals. Areas of commonality and distinction between the two conditions were identified. Integrated health promotion efforts that focus on shared risk (e.g., low self-esteem, body dissatisfaction) and protective (e.g., healthy eating, regular exercise) factors were supported. Suggested target groups for such efforts included young children, adolescents and parents. CONCLUSIONS: The findings indicate areas where the EDs and obesity fields have common ground and can work together in developing integrated health promotion programs.

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.
