To examine the effect of a novel 12 week, dietitian-led nutrition curriculum on dietary change. Pilot interventional study. Community based, cardiac and pulmonary rehabilitation programs with participants that were ambulatory, older adults with chronic cardiac and/or pulmonary disease. Twelve short (∼10min) weekly talks on diverse nutritional topics delivered by a registered dietitian (CPK). Topics were aimed to be most relevant for older adults, those with chronic cardiac/pulmonary and those exercising regularly. Demographics and attitudes to the seminar were collected with a self-reported questionnaire. One hundred and twelve (83 male) attended >75% of talks. The weekly talks were rated as excellent by 38, very good by 52 and good by 13 subjects. Further, weekly talks were rated as very useful, quite useful or useful by 33, 37 and 34 subjects as well as very practical, quite practical or practical by 66, 35 and 6 subjects respectively. One hundred percent of respondents would recommended the ‘curriculum’ to a friend. Eighty-seven of 102 subjects reported having changed their dietary habits since the beginning of the curriculum. The largest reported changes were increased consumption of plant protein (n=37), fruit and vegetables (n=35) and wholegrains (n=11). Nutrition has a major influence on incidence and progression of cardiorespiratory disorders. However, work from our group and others demonstrates both suboptimal nutritional knowledge and behaviours in these cohorts. Rehabilitation programs offer a unique and promising opportunity to provide targeted, evidence-based nutritional advice and potentially modify nutritional behaviours.
