Causes, effects and moral evaluation Sarah Cullum, Rachael Simpson, Farzana Gounder Dementia in New Zealand is expected to triple in the next 30 years at which point 170,000 people and their families will be affected. The media play an important role in not only disseminating information to the public but also shaping opinions and behaviours towards families living with dementia. We examined New Zealand’s three largest daily newspapers and found that dementia is still largely portrayed from a victimhood viewpoint. Up to 40% of dementia is potentially preventable and positive media representation could empower the public regarding attitudes towards dementia. Patient characteristics and predictors of completion of a pulmonary rehabilitation programme in Auckland, New Zealand Sarah Candy, Nicola Jepsen, Christin Coomarasamy, Jonathan Curry, Grace Dodson, Joe Pomelile, Mitchel Versey, Julie Reeve Pulmonary rehabilitation (PR) for people living with a long-term respiratory illness is an effective intervention which can reduce symptoms and improve health-related quality of life. Despite the compelling evidence for this intervention, attendance and completion of PR worldwide is low. Our study identifi ed predictors to completion of a PR programme in Counties Manukau, New Zealand. Being of an older age group, having a higher exercise capacity and of European ethnicity was found to be independent predictor of completion in this cohort. Future service improvements in the provision and delivery of PR programmes in New Zealand need to ensure we are providing accessible options for younger participants, supporting those with lower exercise tolerance and ensure services are engaging for all ethnicities. A feasibility study investigating the impact of a dietitian-led low in fermentable oligosaccharide, disaccharide, monosaccharide and polyols diet group education programme with irritable bowel syndrome Dorcas Chan, Paula Skidmore, Leigh O’Brien, Sally Watson, Richard Gearry Many people have irritable bowel syndrome (abdominal pain with diarrhoea, constipation). Treatments are limited but a special diet called low FODMAP diet can help. Usually a dietitian needs to teach this one on one with the patient, but this study has shown that it is feasible to teach this in a group setting. Are over-the-counter sh oil supplements safe, effective and accurate with labelling? Analysis of 10 New Zealand sh oil supplements Julia J Rucklidge, Ian C Shaw The study shows that 90% of the most popular fi sh oil supplements sold in New Zealand are true to label based on the stated capsule omega fatty acid content. All of the products studied indicated benefi ts across heart, brain and joint health. Based on studies published in scien- tifi c journals, 30% of the products would result in benefi ts across heart, brain and joint health when taken at the top dose recommended on the label. Mercury was not found in any of the samples analysed; therefore, even if some of the products might not confer health benefi ts at the recommended
