Summary A growing body of evidence suggests that diet quality may predict muscle health. This study found that a “Traditional” dietary pattern predicted greater muscle mass, and an anti-inflammatory diet predicted greater muscle mass and better muscle function over 15 years. These findings reinforce the importance of optimising dietary behaviours for healthy ageing. Introduction Research investigating the roles of individual nutrients in muscle health fails to account for the synergistic relationships between foods and nutrients. This study aimed to investigate the predictive value of diet quality and dietary patterns for muscle mass and function in men over a 15-year period. Methods This longitudinal study was conducted in 522 men from the Geelong Osteoporosis Study with complete dietary and muscle mass or muscle function data at both baseline and 15-year follow-up assessments. Dietary exposures were extracted from food frequency questionnaires and included the Australian Recommended Food Score, the Dietary Inflammatory Index (DII®), and three a posteriori dietary patterns: Plant-focused, Western, and Traditional (Anglo-Australian). Outcome variables included dual-energy X-ray absorptiometry–derived skeletal muscle index (SMI) and muscle function measured with the timed up-and-go (TUG) test. Results An anti-inflammatory diet and higher scores on a Traditional dietary pattern both predicted greater SMI ((B: −0.04 (95%CI −0.08, −0.00) kg/m2) and (B: 0.12 (95%CI 0.04, 0.20) kg/m2), respectively), while a pro-inflammatory diet predicted slower TUG (B: 0.11 (95%CI 0.001, 0.21) sec) over the 15-year follow-up period. These associations remained significant following adjustment for confounding variables. There were no associations observed for other dietary exposures. Conclusion A Traditional dietary pattern higher in vegetables, wholegrain cereals, and animal protein was associated with greater skeletal muscle mass, and an anti-inflammatory diet, also rich in vegetables, fruit, and wholegrain cereals, was associated with greater skeletal muscle mass and better muscle function over 15 years.

There has been a prolonged increase in the sale and consumption of ultra-processed, discretionary foods and ultra-processed milks for toddlers, which display numerous on-pack claims that influence health perceptions. This study investigated the relative impact of different regulated and unregulated claims on parent perceptions of the healthiness of a toddler snack food and milk in Australia. Participants aged 18+ years completed an online survey, including discrete choice experiments for an ultra-processed, discretionary toddler snack food and an ultra-processed toddler milk, which displayed combinations of claims across nutrition, health, and other domains. Participants were asked to choose the 'most and least healthy' products between three alternatives over seven choice sets. Data were analysed using an ordinal logistic regression model. Likelihood-ratio tests revealed the most important contribution was variation in regulated nutrition-content claims. For the toddler snack, participants were nearly 14 times more likely to perceive a product with the regulated nutrition-content claim "no added sugar, no added salt" as most healthy (OR 13.71, p 0.001), compared to when no regulated nutrition-content claim was present. For the toddler milk, participants were more than two and a half times more likely to choose a product that contained the regulated nutrition-content claim "2 serves = up to 50% of RDI recommended dietary intake of 14 vitamins and minerals" as most healthy (OR 2.65, p 0.001) compared to when no regulated nutrition-content claim was present. In Australia, regulated nutrition-content claims can be displayed on packaged foods regardless of healthiness. These results indicate that such claims increase perceptions of healthiness of ultra-processed, discretionary toddler snack foods and ultra-processed toddler milks. Further controls are required to regulate the use of nutrition-content and health claims to facilitate informed consumer choice.

BACKGROUND/AIM Demand for occupational therapy graduates able to work in complex and diverse workplaces is increasing. The threshold concepts framework has emerged as one pathway to assist in the development of work-ready graduates. A previous Australian study identified 10 threshold concepts for occupational therapy; the aim of this study was to explore the acquisition of these. METHOD A mixed-methods study using observational, cross sectional design and a triangulation design convergence model was undertaken. A survey using Likert scales and open response questions was developed by the authors. Seventy-three surveys were completed by 13 first and 20 final year Victorian occupational therapy students. Twenty recent graduates and 20 experienced clinicians from across Australia also participated. Seven first and 10 final year occupational therapy students, 10 recent graduates and 10 experienced clinicians also took part in in-depth interviews. Likert scales were used by participants to rate confidence that they had acquired the threshold concepts, they also answered open-response questions (via survey or interview) asking them to provide examples of how they would use threshold concepts in practice. RESULTS Fourth year students were statistically significantly less confident than experienced clinicians for the threshold concepts Understanding the models and theories of occupational therapy and Applying clinical reasoning (P

Consumer-directed care (CDC) is increasingly widespread among aged care service options in Organisation for Economic Co-operation and Development (OECD) countries. However, the evidence base regarding the programmatic and contextual factors that affect the outcome of CDC interventions is surprisingly small. This paper reports on a self-directed care approach for older Australians with complex care needs. A multi-methods longitudinal comparative cohort study was employed comprising 4 survey tools and 56 semi-structured interviews. Participation rates were around 20%. A total of 185 (98 in the intervention and 87 in the control group) older people and carers were recruited at baseline. Eleven months later, 109 participants (59 in the intervention and 50 in the control group) completed the repeat measure. Attrition rates were around 40%. Data collection occurred between July 2010 and April 2012. The data suggest that intervention group participants were likely to be more satisfied with the way they were treated (P = 0.013), their care options (P = 0.014), the ‘say’ they had in their care (P

Background The possible therapeutic impact of dietary changes on existing mental illness is largely unknown. Using a randomised controlled trial design, we aimed to investigate the efficacy of a dietary improvement program for the treatment of major depressive episodes. Methods ‘SMILES’ was a 12-week, parallel-group, single blind, randomised controlled trial of an adjunctive dietary intervention in the treatment of moderate to severe depression. The intervention consisted of seven individual nutritional consulting sessions delivered by a clinical dietician. The control condition comprised a social support protocol to the same visit schedule and length. Depression symptomatology was the primary endpoint, assessed using the Montgomery–Åsberg Depression Rating Scale (MADRS) at 12 weeks. Secondary outcomes included remission and change of symptoms, mood and anxiety. Analyses utilised a likelihood-based mixed-effects model repeated measures (MMRM) approach. The robustness of estimates was investigated through sensitivity analyses. Results We assessed 166 individuals for eligibility, of whom 67 were enrolled (diet intervention, n = 33; control, n = 34). Of these, 55 were utilising some form of therapy: 21 were using psychotherapy and pharmacotherapy combined; 9 were using exclusively psychotherapy; and 25 were using only pharmacotherapy. There were 31 in the diet support group and 25 in the social support control group who had complete data at 12 weeks. The dietary support group demonstrated significantly greater improvement between baseline and 12 weeks on the MADRS than the social support control group, t(60.7) = 4.38, p
