This chapter reviews the importance of diabetes as a major complication of obesity, starting with examining the epidemiological relationship between diabetes and obesity. It is clear from the epidemiological data reported that obesity is strongly associated with onset and, in particular, the premature onset, of type 2 diabetes. However, in established heart disease and heart failure, obesity is associated with lower mortality. The chapter considers the epidemiological evidence linking adiposity with the development of cancer, and describes the proposed mechanisms by which excess body fat may impact on cancer risk. The global prevalence of osteoarthritis continues to rise, both because of an ageing population as well as because of the current obesity epidemic, with obesity in the elderly becoming an increasing problem. The chapter explains individual psychosocial factors and views them as part of a vicious circle, including personal beliefs. The combination of binge eating and obesity is particularly problematic with regard to comorbidity and risk.

In 2006 the avian influenza A (H5N1) virus received considerable media coverage in Australia, as it did in many other countries. It is often argued that the media sensationalizes health crises, and experts cautioned about the risk of panic as a result of fear of avian influenza. The purpose of the present study was to systematically analyze Australian print media coverage of avian influenza in 2006 and to examine whether this coverage served the purpose of informing, rather than alarming, the general public. For the period January 1, 2006 to December 31, 2006, 20 Australian newspaper titles were monitored for coverage of avian influenza. The identified articles were analyzed using aspects of protection motivation theory for theoretical direction to determine whether there were any consistent themes or perspectives in the coverage. A total of 850 articles were identified for analysis. Concerning vulnerability, 46% of articles reported the incidence of human cases, with 24% noting that avian influenza was a potential threat to Australia. The most common severity theme was “deadly” with over 50% of mentions, followed by “pandemic” with 35%. Only 11% of articles referred to any form of self-protection. We found that a considerable proportion of the articles reporting on avian influenza were framed in a way that had the potential to incite fear and panic amongst the public; the intensity of media coverage reduced over time; and, of particular concern, that there was little media coverage that focused on protective or preventative issues. Whether an influenza pandemic eventuates or not, it is prudent for governments and health authorities to continually develop appropriate resources and strategies to prepare the health system and the general public to respond to current, and future, infectious disease risks.

Issue addressed: To evaluate the effectiveness of a brief intervention using a pedometer and step-recording diary on promoting physical activity in people with type 2 diabetes or impaired glucose tolerance (IGT). Methods: People with type 2 diabetes or IGT who attended the Illawarra Diabetes Service were invited to participate. Participants in the intervention group received a pedometer and a diary to record their daily steps for a two-week period. Both the intervention and comparison group received advice on physical activity. Physical activity levels were measured using the Active Australia Survey at baseline, and at two and 20 weeks. Results: A total of 226 participants were recruited. At two-week follow-up the mean self-reported minutes of walking was significantly higher in the intervention group than the comparison group (223 minutes versus 164 minutes; p=0.01), as was the percentage of intervention participants achieving recommended levels of moderate-intensity physical activity (63.5% versus 41.8%, p=0.02) and the percentage of intervention participants achieving adequate levels of total physical activity (68.9% versus 48.0%, p=0.04). There were no differences between study groups for any physical activity measure at 20-week follow-up. Conclusions: A pedometer and a step-recording diary were useful tools to promote short-term increase in physical activity in people diagnosed with type 2 diabetes or IGT. Future studies need to examine whether a longer intervention, individualised physical activity counselling and support for achieving step goals could result in increasing physical activity over the long term.

Background Cognitive behavioural therapy (CBT) is recommended for the treatment of depression and anxiety. However, access is limited. Low-intensity approaches such as guided CBT self-help (bibliotherapy) can increase access to treatment and is recommended by UK guidelines. No previous research has explored the provision of group-based guidance/support for a bibliotherapy approach for depression and anxiety in community settings. The objective was to carry out a pilot study of a group guided self-help intervention, using community based recruitment methods. Method A randomised controlled trial comparing an 8 week CBT group guided self-help intervention to usual care. Recruitment and the delivery of the intervention were carried out in Glasgow and Derry/Londonderry in partnership with national depression charities. Fifty-three people were randomised, however we refer only to the forty-six participants who provided baseline data: 16 males and 30 females, aged 16 or over, with a PHQ-9 score of ≥ 5, were recruited from the community. The mean age of the sample was 43.7 (sd = 13) and 93.5% of participants had suffered from low mood for a year or more. Results There was effective recruitment, randomisation, uptake and adherence with 21 Immediate Access (IA) and 25 Delayed Access Control (DAC) participants. The intervention was highly acceptable to participants attending on average 4.46 of the 8 sessions (sd 3.06), 65.2% attended more than half of all sessions. The mean satisfaction on the Client Satisfaction Questionnaire was 28 out of 32 (sd 4.8). The provisional results in the pilot suggest the intervention may improve both anxiety and depression. At three months, data collection was achieved from 74% of participants. The trial successfully provided estimates of the sample size needed for the future planned trial. Conclusions Low-intensity group-based classes may offer an alternative method of managing depression and anxiety and warrant further research.

Background: Bulimia nervosa (BN) is an eating disorder with many physical, psychological and social consequences. Guided self-help (GSH) is recommended in the treatment of BN (NICE, 2004). One of the ways in which to provide GSH is via the internet using evidence-based packages with regular support from a clinician or trained support worker. Aims: The aim of this community-based survey was to investigate attitudes towards online self-help for eating disorders and the support required whilst using such an approach. Method: Two-hundred and fifty-three participants with bulimic symptoms completed the survey. The sample was recruited primarily online. The mean age was 29.11 years (SD = 8.67; min = 16, max = 64). Results: Attitudes towards online self-help (SH) for eating disorders were very positive. The inclusion of some form of support to accompany such an intervention was important to the majority of participants. Remote mediums of support such as e-mail, a forum and text messaging were most often selected as helpful. Most participants expressed a preference for weekly support contacts and for flexible support lengths that could respond to support needs as required. Conclusions: Online self-help for eating disorders is a desirable treatment option for many individuals. The information gathered regarding preferences in the type, medium, duration and frequency of support could be used in the development of future self-help strategies in order to maximize uptake, retention and outcomes.
