Abstract
This study evaluated a gender-specific, school-based program to promote positive body image and address risk factors for body dissatisfaction. In total, 652 children aged 8-10 years participated (335 intervention, 317 wait-list control). Children participated in four 60min sessions and a recap session at three months post-intervention. The broad content areas were body image, peer relationships, media awareness, healthy diet, and exercise. The activities and examples for each session were gender specific. The recap session was an overview of the four sessions. Assessment measures were completed at pre-intervention, post-intervention, and after the recap. Boys and girls in the intervention demonstrated higher muscle esteem and vegetable intake at post-intervention, compared to children in the control condition. Boys and girls demonstrated higher body esteem, muscle esteem and fruit and vegetable intake at the recap. Boys in the intervention demonstrated less investment in masculine gender norms at post-intervention and at recap.

Abstract
BACKGROUND There is a paucity of studies evaluating targeted obesity prevention interventions in pre-school children. OBJECTIVES We conducted a randomized controlled trial to evaluate the efficacy of a parent-based obesity prevention intervention for pre-schoolers - MEND (Mind, Exercise, Nutrition … Do It!) 2-4 on child diet, eating habits, physical activity/sedentary behaviours, and body mass index (BMI). METHODS Parent-child dyads attended 10 weekly 90-min workshops relating to nutrition, physical activity and behaviours, including guided active play and healthy snack time. Assessments were conducted at baseline, immediately post-intervention, and 6 and 12 months post-intervention; child intake of vegetables, fruit, beverages, processed snack foods, fussiness, satiety responsiveness, physical activity, sedentary behaviour and neophobia were assessed via parent proxy report. Parent and child height and weight were measured. RESULTS Two hundred one parent-child dyads were randomized to intervention (n = 104) and control (n = 97). Baseline mean child age was 2.7 (standard deviation [SD] 0.6) years, and child BMI-for-age z-score (World Health Organization) was 0.66 (SD 0.88). We found significant positive group effects for vegetable (P = 0.01) and snack food (P = 0.03) intake, and satiety responsiveness (P = 0.047) immediately post-intervention. At 12 months follow-up, intervention children exhibited less neophobia (P = 0.03) than controls. CONCLUSION Future research should focus on additional strategies to support parents to continue positive behaviour change. ACTRN12610000200088.

Abstract
BACKGROUND AND AIMS Single checking medications has been increasingly adopted over the past decade by nurses in Australian healthcare services. However, attitudes toward the practice of only one nurse checking medications remain unclear. The aim of this article is to report on the development, reliability, and validity of a tool to measure nurses' attitudes to single checking medications in a health service in which single checking has been in place for over a decade. METHODS In a cross-sectional survey design, the Single Checking and Administration of Medications Scale (SCAMS-II) was used to measure the attitudes of 299 registered nurses (RNs) who were single checking medications in one metropolitan teaching hospital in Australia. Exploratory factor analysis was used to explore the dimensions that best represented the SCAMS-II. Cronbach's α was used to assess internal consistency of the identified subscales. To test the construct validity of the emergent questionnaire, Confirmatory Factor Analysis and Rasch analyses were performed. RESULTS The psychometric properties of the SCAMS-II revealed 12 items with three reliable subscales: a five-item accountability model; a four-item efficiency model; and a three-item knowledge model. LINKING EVIDENCE TO ACTION In settings where single checking is current practice, the SCAMS-II is recommended as a reliable tool to measure nurses' attitudes toward the single checking of medications. The findings from this study may assist healthcare organizations in the development of policy and procedure guidelines for the safe administration of medications.

Abstract
Background Falls are a major public health concern with at least one third of people aged 65 years and over falling at least once per year, and half of these will fall repeatedly, which can lead to injury, pain, loss of function and independence, reduced quality of life and even death. Although the causes of falls are varied and complex, the age-related loss in muscle power has emerged as a useful predictor of disability and falls in older people. In this population, the requirements to produce explosive and rapid movements often occurs whilst simultaneously performing other attention-demanding cognitive or motor tasks, such as walking while talking or carrying an object. The primary aim of this study is to determine whether dual-task functional power training (DT-FPT) can reduce the rate of falls in community-dwelling older people. Methods/Design The study design is an 18-month cluster randomised controlled trial in which 280 adults aged ≥65 years residing in retirement villages, who are at increased risk of falling, will be randomly allocated to: 1) an exercise programme involving DT-FPT, or 2) a usual care control group. The intervention is divided into 3 distinct phases: 6 months of supervised DT-FPT, a 6-month ‘step down’ maintenance programme, and a 6-month follow-up. The primary outcome will be the number of falls after 6, 12 and 18 months. Secondary outcomes will include: lower extremity muscle power and strength, grip strength, functional assessments of gait, reaction time and dynamic balance under single- and dual-task conditions, activities of daily living, quality of life, cognitive function and falls-related self-efficacy. We will also evaluate the cost-effectiveness of the programme for preventing falls. Discussion The study offers a novel approach that may guide the development and implementation of future community-based falls prevention programmes that specifically focus on optimising muscle power and dual-task performance to reduce falls risk under ‘real life’ conditions in older adults. In addition, the ‘step down’ programme will provide new information about the efficacy of a less intensive maintenance programme for reducing the risk of falls over an extended period.

Abstract
AIMS We tested whether patrons of the night-time economy who had co-consumed energy drinks or illicit stimulants with alcohol had higher blood alcohol concentration (BAC) levels than patrons who had consumed only alcohol. DESIGN Street intercept surveys (n = 4227) were undertaken between 9 p.m. and 5 a.m. over a period of 7 months. SETTING Interviews were undertaken with patrons walking through entertainment precincts, queuing to enter venues or exiting venues in five Australian cities. PARTICIPANTS The response rate was 92.1%; more than half the study sample was male (60.2%) and the median age was 23 years (range 18-72). MEASUREMENTS Data were collected on demographics, length of drinking session, venue types visited, types and quantity of alcohol consumed and other substance use. A BAC reading was recorded and a subsample of participants was tested for other drug use. FINDINGS Compared with the total sample (0.068%), illicit stimulant consumers (0.080%; P = 0.004) and energy drink consumers (0.074%; P < 0.001) had a significantly higher median BAC reading, and were more likely to engage in pre-drinking (65.6, 82.1 and 77.6%, respectively, P < 0.001) and longer drinking sessions (4, 5 and 4.5 hours, respectively, P < 0.001). However, stimulant use was not associated independently with higher BAC in the final multivariable model (illicit stimulants P = 0.198; energy drinks P = 0.112). Interaction analyses showed that stimulant users had a higher BAC in the initial stages of the drinking session, but not after 4-6 hours. CONCLUSIONS While stimulant use does not predict BAC in and of itself, stimulants users are more likely to engage in prolonged sessions of heavy alcohol consumption and a range of risk-taking behaviours on a night out, which may explain higher levels of BAC among stimulants users, at least in the initial stages of the drinking session.

Abstract
This study determined how sociocultural messages to change one's body are perceived by adolescents from different cultural groups. In total, 4904 adolescents, including Australian, Chilean, Chinese, Indo-Fijian, Indigenous Fijian, Greek, Malaysian, Chinese Malaysian, Tongans in New Zealand, and Tongans in Tonga, were surveyed about messages from family, peers, and the media to lose weight, gain weight, and increase muscles. Groups were best differentiated by family pressure to gain weight. Girls were more likely to receive the messages from multiple sociocultural sources whereas boys were more likely to receive the messages from the family. Some participants in a cultural group indicated higher, and others lower, levels of these sociocultural messages. These findings highlight the differences in sociocultural messages across cultural groups, but also that adolescents receive contrasting messages within a cultural group. These results demonstrate the difficulty in representing a particular message as being characteristic of each cultural group.

Abstract
BACKGROUND Although a wealth of studies have tested the link between negative mood states and likelihood of a subsequent binge eating episode, the assumption that this relationship follows a typical linear dose-response pattern (i.e., that risk of a binge episode increases in proportion to level of negative mood) has not been challenged. The present study demonstrates the applicability of an alternative, non-linear conceptualization of this relationship, in which the strength of association between negative mood and probability of a binge episode increases above a threshold value for the mood variable relative to the slope below this threshold value (threshold dose response model). METHODS A sample of 93 women aged 18 to 40 completed an online survey at random intervals seven times per day for a period of one week. Participants self-reported their current mood state and whether they had recently engaged in an eating episode symptomatic of a binge. RESULTS As hypothesized, the threshold approach was a better predictor than the linear dose-response modeling of likelihood of a binge episode. The superiority of the threshold approach was found even at low levels of negative mood (3 out of 10, with higher scores reflecting more negative mood). Additionally, severity of negative mood beyond this threshold value appears to be useful for predicting time to onset of a binge episode. CONCLUSIONS Present findings suggest that simple dose-response formulations for the association between negative mood and onset of binge episodes miss vital aspects of this relationship. Most notably, the impact of mood on binge eating appears to depend on whether a threshold value of negative mood has been breached, and elevation in mood beyond this point may be useful for clinicians and researchers to identify time to onset.

Abstract
BACKGROUND The Rapid Assessment of Disability (RAD) questionnaire measures the magnitude and impact of disability and aims to inform the design of disability inclusive development programs. This paper reports the psychometric evaluation of the RAD. METHODS The initial version of the RAD comprised five sections: 1) demographics, 2) functioning, 3) rights awareness, 4) well-being, and 5) access to the community. Item functioning and construct validity were assessed in a population-based study in Bangladesh. Data were analysed using descriptive statistics (sections 2 and 5) and Rasch modelling (sections 3 and 4). A subsequent case-control study in Fiji tested the refined questionnaire in a cross-cultural setting and assessed the sensitivity and specificity of the RAD section 2 to identify people with disability. RESULTS 2,057 adults took part in the study (1,855 in Bangladesh and 202 in Fiji). The prevalence of disability estimated using RAD section 2 in Bangladesh was 10.5% (95% CI 8.8-12.2), with satisfactory sensitivity and specificity (62.4% and 81.2%, respectively). Section 3 exhibited multidimensionality and poor differentiation between levels of rights awareness in both Bangladesh (person separation index [PSI] = 0.71) and Fiji (PSI = 0.0), and was unable to distinguish between people with and without disability (Bangladesh p = 0.786, Fiji p = 0.43). This section was subsequently removed from the questionnaire pending re-development. Section 4 had good ability to differentiate between levels of well-being (PSI = 0.82). In both countries, people with disability had significantly worse well-being scores than people without disability (p < 0.001) and also access to all sectors of community except legal assistance, drinking water and toilets (p < 0.001). CONCLUSIONS Filed-testing in Bangladesh and Fiji confirmed the psychometric robustness of functioning, well-being, and community access sections of the RAD. Information from the questionnaire can be used to inform and evaluate disability inclusive development programs.

Abstract
Autism Spectrum Disorder (ASD) has been associated with essential fatty acid (EFA) deficiencies, with some researchers theorising that dysregulation of phospholipid metabolism may form part of the biological basis for ASD. This pilot study compared observable signs of fatty acid status of 19 children with an ASD diagnosis to 23 of their typically developing siblings. A pregnancy, birth and breastfeeding history was also obtained from their parents, which included a measure of infant intake of fatty acid rich colostrum immediately post-partum. When considered within their family group, those infants not breastfed (with colostrum) within the first hour of life and who had a history of fatty acid deficiency symptoms were more likely to have an ASD diagnosis. Other variables such as formula use, duration of breastfeeding, gestational age and Apgar scores were not associated with group membership. The results of this study are consistent with previous research showing a relationship between fatty acid metabolism, breastfeeding and ASD such that early infant feeding practices and the influence this has on the fatty acid metabolism of the child may be a risk factor for ASD.

Abstract
Background and Purpose—
Previous economic studies outside Australia have demonstrated that patients treated with tissue-type plasminogen activator (tPA) within 4.5 hours of stroke onset have lower healthcare costs than those not. We aim to perform cost-effectiveness analysis of intravenous tPA in an Australian setting.
Methods—
Data on clinical outcomes and costs were derived for 378 patients who received intravenous tPA within 4.5 hours of stroke onset at Royal Melbourne Hospital (Australia) between January 2003 and December 2011. To simulate clinical outcomes and costs for a hypothetical control group assumed not to have received tPA, we applied efficacy data from a meta-analysis of randomized trials to outcomes observed in the tPA group. During a 1-year time-horizon, net costs, years of life lived, and quality-adjusted life-years were compared and incremental cost-effectiveness ratios derived for tPA versus no tPA.
Results—
In the study population, mean (SD) age was 68.2 (13.5) years and 206 (54.5%) were men. Median National Institutes of Health Stroke Scale score (interquartile range) at presentation was 12.5 (8–18). Compared with no tPA, we estimated that tPA would result in 0.02 life-years and 0.04 quality-adjusted life-years saved per person >1 year. The net cost of tPA was AUD $55.61 per patient. The incremental cost-effectiveness ratios were AUD $2377 per life-year saved and AUD $1478 per quality-adjusted life-years saved. Because the costs of tPA are incurred only once, the incremental cost-effectiveness ratios would decrease with increasing time-horizon. Uncertainty analyses indicated the results to be robust.
Conclusions—
Intravenous tPA within 4.5 hours represents a cost-effective intervention for acute ischemic stroke.

Abstract
OBJECTIVE To develop a conceptual model to describe the burden of osteoarthritis in individuals with this condition and on the broader community. STUDY DESIGN AND SETTING Six concept mapping workshops were undertaken: three with patients (n = 26) and three with health professionals (n = 27) in Australia and Sweden. The participants were asked to generate statements describing how osteoarthritis affects individuals with this condition and those around them. The results were used to construct an integrated theoretical model of the personal burden of osteoarthritis (PBO) and its extended version, the personal and societal burden of osteoarthritis (PSBO) model. RESULTS We identified eight potentially independent aspects of PBO, including physical distress, fatigue, physical limitations, psychosocial distress, physical deconditioning, financial hardship, sleep disturbances, and lost productivity. Physical distress and impaired physical function combined to produce psychosocial problems, reduced work productivity, financial difficulties, and loss of physical fitness at the individual level, and increased health and welfare cost at the societal level. CONCLUSION The PBO and PSBO models were developed directly from the views of patients and clinicians and provide new insights for managing the individual and societal burden of osteoarthritis.

Abstract
BACKGROUND Stroke is one of the most disabling neurological conditions. Clinical research is vital for expanding knowledge of treatment effectiveness among stroke patients. However, evidence begins to accumulate that stroke patients who take part in research represent only a small proportion of all stroke patients. Research participants may also differ from the broader patient population in ways that could potentially distort treatment effects reported in therapeutic trials. The aims of this study were to estimate the proportion of stroke patients who take part in clinical research studies and to compare demographic and clinical profiles of research participants and non-participants. METHODS 5,235 consecutive patients admitted to the Stroke Care Unit of the Royal Melbourne Hospital, Melbourne, Australia, for stroke or transient ischaemic attack between January 2004 and December 2011 were studied. The study used cross-sectional design. Information was collected on patients' demographic and socio-economic characteristics, risk factors, and comorbidities. Associations between research participation and patient characteristics were initially assessed using χ(2) or Mann-Whitney tests, followed by a multivariable logistic regression analysis. The logistic regression analysis was carried out using generalised estimating equations approach, to account for patient readmissions during the study period. RESULTS 558 Stroke Care Unit patients (10.7%) took part in at least one of the 33 clinical research studies during the study period. Transfer from another hospital (OR = 0.35, 95% CI 0.22-0.55), worse premorbid function (OR = 0.61, 95% CI 0.54-0.70), being single (OR = 0.61, 95% CI 0.44-0.84) or widowed (OR = 0.77, 95% CI 0.60-0.99), non-English language (OR = 0.67, 95% CI 0.53-0.85), high socio-economic status (OR = 0.74, 95% CI 0.59-0.93), residence outside Melbourne (OR = 0.75, 95% CI 0.60-0.95), weekend admission (OR = 0.78, 95% CI 0.64-0.94), and a history of atrial fibrillation (OR = 0.79, 95% CI 0.63-0.99) were associated with lower odds of research participation. A history of hypertension (OR = 1.50, 95% CI 1.08-2.07) and current smoking (OR = 1.23, 95% CI 1.01-1.50) on the other hand were associated with higher odds of research participation. CONCLUSIONS The results of this study indicate that stroke patients who take part in clinical research do not represent 'typical' patient admitted to a stroke unit. The imbalance of prognostic factors between stroke participants and non-participants has serious implications for interpretation of research findings reported in stroke literature. This study provides insights into clinical, demographic, and socio-economic characteristics of stroke patients that could potentially be targeted to enhance generalizability of stroke research studies. Given the imbalance of prognostic factors between research participants and non-participants, future studies need to examine differences in stroke outcomes of these groups of patients.

Abstract
OBJECTIVE To develop a conceptual framework for the design of an in-home monitoring system (IMS) based on the requirements of older adults with vision impairment (VI), informal caregivers and eye-care rehabilitation professionals. MATERIALS AND METHODS Concept mapping, a mixed-methods statistical research tool, was used in the construction of the framework. Overall, 40 participants brainstormed or sorted and rated 83 statements concerning an IMS for older adults with VI. Multidimensional scaling and hierarchical cluster analysis were employed to construct the framework. A questionnaire yielded further insights into the views of a wider sample of older adults with VI (n=78) and caregivers (n=25) regarding IMS. RESULTS Concept mapping revealed a nine-cluster model of IMS-related aspects including affordability, awareness of system capabilities, simplicity of installation, operation and maintenance, system integrity and reliability, fall detection and safe movement, user customization, user preferences regarding information delivery, and safety alerts for patients and caregivers. From the questionnaire, independence, safety and fall detection were the most commonly reported reasons for older adults and caregivers to accept an IMS. Concerns included cost, privacy, security of the information obtained through monitoring, system accuracy, and ease of use. DISCUSSION Older adults with VI, caregivers and professionals are receptive to in-home monitoring, mainly for fall detection and safety monitoring, but have concerns that must be addressed when developing an IMS. CONCLUSION Our study provides a novel conceptual framework for the design of an IMS that will be maximally acceptable and beneficial to our ageing and vision-impaired population.

Abstract
OBJECTIVE Health literacy refers to an individual's ability to seek, understand, and use health information. This paper describes the development and psychometric testing of the health literacy management scale (HeLMS). METHODS Content areas were identified from a conceptual framework derived from interviews and concept mapping. Items were generated from statements from concept mapping participants. Construction (N=333) and replication (N=350) samples were participants in chronic disease self-management programs and emergency department attendees. Factor analysis was used to refine constructs and define psychometric properties. RESULTS Consultations generated 8 scales each with 4-5 items: Understanding health information, Accessing GP healthcare services, Communication with health professionals, Being proactive and Using health information, Patient attitudes towards their health, Social support, and Socioeconomic considerations. Confirmatory factor analyses indicated good fit of the data with the model (RMSEA=0.07, SRMR=0.05, CFI=0.97) and all domains had high internal consistency (Cronbach alpha>0.82). CONCLUSION The HeLMS has acceptable psychometric properties and assesses a range of health literacy constructs important to patients when seeking, understanding and using health information within the healthcare system. PRACTICE IMPLICATIONS The HeLMS presents a new approach to assessing health literacy in healthcare settings.

Abstract
In this study, we examined the relationship between exposure to siblings and 1) the risk of age-related macular degeneration (AMD) and 2) C-reactive protein levels. We retrospectively analyzed pooled cross-sectional data from 2 studies: the Cardiovascular Health and Age-Related Maculopathy Study (2001-2002) and the Age-Related Maculopathy Statin Study (2004-2006). Associations between number of siblings and AMD were assessed by using multinomial logistic regression. Associations between number of siblings and C-reactive protein levels were examined by using a generalized linear model for γ distribution. A higher number of younger siblings was associated with significantly lower odds of early AMD in those with a family history of AMD (odds ratio = 0.2, 95% confidence interval: 0.1, 0.8) (P = 0.022) but was unrelated to AMD for those who had no family history of the disease (odds ratio = 1.0, 95% confidence interval: 0.9, 1.2) (P = 0.874). A higher number of younger siblings correlated with lower C-reactive protein levels (β = -0.19, 95% confidence interval: -0.38, -0.01) (P = 0.036). This supports the theory that immune modulation contributes to AMD pathogenesis and suggests that exposure to younger siblings might be protective when there is a family history of AMD.

Abstract
Introduction:
Traditional approaches to the study of post stroke recovery assume that recovery follows a homogenous path, with deviations from the average explained in terms of socio-demographic and clinical differences. Latent class analysis (LCA) provides a powerful tool to investigate potential heterogeneity in post-stroke recovery pathways.
Aims:
We aimed to 1) explore recovery trajectories in acute stroke over 3 months using LCA and 2) identify predictors of poor recovery.
Methods:
Data from 202 patients admitted to Stroke Care Unit at the Royal Melbourne Hospital (Australia) between January and June 2011 were analyzed. The main outcome was disability (modified Rankin Score) pre-stroke, at discharge, and 3 months post stroke. Predictors of poor recovery were assessed using logistic regression analysis.
Results:
Patients’ mean (SD) age was 68.6 (14.1), 58% were males and 82% had ischemic strokes. LCA identified 6 mutually exclusive recovery trajectories (see Figure 1), including: 1) No disability at onset, no impact from stroke (n=43); 2) Substantial disability, no impact from stroke (n=20); 3) Some disability, mild impact, full recovery (n=36); 4) No disability, mild impact, partial recovery (n=26); 5) No disability, high impact, partial recovery (n=50); 6) No disability, high impact, no recovery (n=27). Compared with those who made at least partial recovery (trajectories 1-5), those who made no recovery at 3 months were significantly younger (OR 0.97 95%CI 0.95,0.99) and more likely to be smokers (OR 2.48 95%CI 1.04,5.90). History of atrial fibrillation, ischemic heart disease, previous stroke, and stroke type were not associated with poor recovery (p≥0.103).
Conclusions:
This study identifies stroke recovery pathways, providing a potentially useful tool for identifying individuals at risk of poor recovery and in need of targeted intervention.

Abstract
PURPOSE To investigate how knowledge and attitudes influence the access to eye-care services in Takeo Province, Cambodia. DESIGN A cross-sectional survey (n=600). METHODS 30 villages were randomly selected. Groups included: >50 years, 30-49 years, and parents with children <5 years. A newly developed Knowledge, Attitude and Practice in Eye Health (KAP-EH) questionnaire about knowledge and treatment of eye diseases, practices and attitudes to accessing services was used to interview respondents. Descriptive analysis, including Chi square and logistic regression tested for associations with sub-groups of gender, age group, education and self-reported type of disability. RESULTS The proportion of respondents who reported having knowledge of specific eye conditions ranged from 97% for eye injury, to 8% for diabetic eye disease. While 509 (85%) people reported knowledge of cataract, 47% did not know how cataract was treated and only 19% listed surgery. The older group (66.5%) were least informed about cataract (p= 0.001) compared to other groups, and were least likely to believe that some blindness could be prevented (p < 0.001). Women (55%) were more likely than men (46%) (p=0 .003) to report that a child with blindness could attend school, as did people without a disability compared to those with a disability (58% vs 34%) (p < 0.001). CONCLUSIONS The knowledge about cataract and refractive error and what to do to resolve the problems was low among this population and this study suggests that poor knowledge of eye diseases might contribute to the occurrence of un-operated cataract and uncorrected refractive error.
