Graphical abstract Image, graphical abstract, Background In response to the COVID-19 pandemic, 6,287 Australian health care workers (HCWs) were fit tested to N95 filtering facepiece respirators (FFRs). This study determined how readily HCWs were fitted to 8 FFRs and how age and sex influenced testing. Methods HCWs were fit tested following the quantitative OSHA protocol. After bivariate analysis, a logistic regression model assessed the effect of FFR model, HCW age and sex on fit test results. Results Of 4,198 female and 2,089 male HCWs tested, 93.3% were successfully fitted. Fifty-five percent passed the first FFR, 21% required 2 and 23% required testing on 3 or more models. Males were 15% less likely to pass compared to females (P < .001). Individuals aged 18-29 were significantly more likely to pass compared to colleagues aged 30-59. Cup-style 3M 1860S was the most suitable model (95% CI: 1.94, 2.54) while the duckbill BSN TN01-11 was most likely to fail (95% CI: 0.11, 0.15). Conclusions Current N95 FFRs exhibit suboptimal fit such that a large proportion (45%) of HCWs require testing on multiple models. Older age and male sex were associated with significantly higher fit failure rates. QNFT programs should consider HCW characteristics like sex, age, racial and facial anthropometric measurements to improve the protection of the health workforce.

Objectives Women who had hypertensive disorders of pregnancy (HDP) are twice as likely to experience maternal cardiovascular disease later in life. The primary aim of this study (BP2) is to compare outcomes of 3 different management strategies, including lifestyle behaviour change (LBC), in the first 12 months postpartum in women who had HDP in their preceding pregnancy. Secondary aims include assessing the effects on other cardiometabolic parameters. Study design Three-arm multicentre randomised trial in metropolitan Australian hospitals, (registration: ACTRN12618002004246) target sample size 480. Participants are randomised to one of three groups: 1) Optimised usual care: information package and family doctor follow-up 6 months postpartum 2) Brief intervention: information package as per group 1, plus assessment and brief LBC counselling at a specialised clinic with an obstetric physician and dietitian 6 months postpartum 3) Extended intervention: as per group 2 plus enrolment into a 6 month telephone-based LBC program from 6 to 12 months postpartum. All women have an outcome assessment at 12 months. Main outcome measures Primary outcomes: (a) BP change or (b) weight change and/or waist circumference change. Secondary outcomes: maternal health-related quality of life, engagement and retention in LBC program, biochemical markers, vascular function testing, infant weight trajectory, incremental cost-effectiveness ratios. The study is powered to detect a 4 mmHg difference in systolic BP between groups, or a 4 kg weight loss difference/2cm waist circumference change. Conclusions BP2 will provide evidence regarding the feasibility and effectiveness of postpartum LBC interventions and structured clinical follow-up in improving cardiovascular health markers after HDP.

Aim This paper outlines the protocol for a feasibility study to examine the dietary and physical activity behaviours of new graduate nurses and to implement and evaluate the effectiveness of a workplace health promotion intervention to assist new graduate nurses in adopting or maintaining behaviours. Design A sequential explanatory mixed-methods study. Methods The study is informed by the Behaviour Change Wheel. It will be conducted for twelve months and will recruit all new graduate nurses employed at a local health district who are participating in a transition to practice program. A workplace health promotion intervention will be embedded in the transition to practice program for the intervention group, allocated according to the hospital of employment. The study will assess changes to health knowledge, dietary habits and physical activity behaviours measured at baseline, 6-weeks and 6-months. Semi-structured interviews will be conducted with intervention group participants at 6-months. Descriptive statistics will be used to present demographic data. Chi-squared Tests of Independence and Generalised Mixed Models will be used to analyse categorical data. Poisson Regression will be used to analyse continuous data. Qualitative data will be analysed thematically. Discussion Nurses need to engage in healthy lifestyle behaviours to ensure they can meet the rising demand for healthcare. However, experienced nurses often have poor dietary and physical activity behaviours. There is limited research examining these behaviours among new graduate nurses as they are starting their careers and forming workplace habits.

Background and objective Nurses are well-placed in primary care, school and community settings to identify and manage paediatric overweight and obesity. This scoping review examined what types of nurse-led interventions have been undertaken for the prevention, treatment and management of obesity and overweight in infants, children and adolescents. Design Scoping review. Data sources CINAHL, Cochrane Library, Embase, MEDLINE, ProQuest Central, ProQuest Dissertations & Theses Global, and Scopus. Searches were undertaken from inception to 2019. Methods Database searches and handsearching were used to identify academic and grey literature, such as scientific reports and university theses and dissertations, on nurse-led interventions undertaken in school, primary health care and community settings. Studies focused on addressing overweight and obesity in children and adolescents, for studies published from 1999 onwards. Studies included focused on experimental and quasi-experimental research that implemented interventions, and described new practice or change in practice. Results 117 references encompassing 83 studies or programs were selected for inclusion. 16 trials were analysed descriptively, and 67 trials were analysed descriptively and quantitatively. The analysis structured intervention settings and outcomes using the socioecological model, encompassing intrapersonal, interpersonal, community, organisation and policy factors. Studies included were clinically heterogeneous for intervention setting and multicomponent strategies. Education for nutrition, physical activity and behaviour change was the most common strategy used, and nutrition and physical activity knowledge most consistently improved after intervention. Nursing roles focused on education; counselling and behaviour change in primary care; advocacy in school and community environments; and implementing policy in child care settings. Fifty-four studies received financial or resource funding and support to implement the study. On sustainability, seven programs and two research studies were ongoing at time of writing. Conclusions While the clinical heterogeneity of studies makes synthesis of outcomes complex, it demonstrates the breadth of nursing interventions to address paediatric overweight and obesity. Incentives that encourage routine health promotion, upskilling of nurses, and embedding food and nutrition education into the school curricula, are suitable strategies that support nurse-led interventions against paediatric obesity.

The aim of this paper was to explore the mentoring experiences of new graduate midwives working in midwifery continuity of care models in Australia. Most new graduates find employment in hospitals and undertake a new graduate program rotating through different wards. A limited number of new graduate midwives were found to be working in midwifery continuity of care. The new graduate midwives in this study were mentored by more experienced midwives. Mentoring in midwifery has been described as being concerned with confidence building based through a personal relationship. A qualitative descriptive study was undertaken and the data were analysed using continuity of care as a framework. We found having a mentor was important, knowing the mentor made it easier for the new graduate to call their mentor at any time. The new graduate midwives had respect for their mentors and the support helped build their confidence in transitioning from student to midwife. With the expansion of midwifery continuity of care models in Australia mentoring should be provided for transition midwives working in this way.

Background: Although cardiovascular absolute risk (CVAR) assessment has been recommended for use in Australian general practice for a number of years, there is continuing uncertainty about its implementation and impact. Our previous work has developed a multifaceted implementation model. This study aims to investigate both the feasibility of using this model and the impact of CVAR assessment and management on general practice clinical processes and patient care. Study Design: This cluster randomized controlled trial will be conducted in general practices in Sydney, involving general practitioners (GPs), other practice staff, and patients aged 45 to 69 years without existing cardiovascular disease. Methods: A total of 32 practices (40 GPs) and 1,320 patients will be recruited. Randomization will be conducted at the practice level. The intervention group of GPs will be trained to use a CVAR implementation model, whereas the control group of GPs will continue usual care. Study outcomes include clinical processes, patient risk, use of lifestyle intervention, and prescription of antihypertensive and lipid-lowering medications. Data will be collected and analyzed using mixed methods. Study outcomes before and after the intervention will be compared, and the 2 groups will also be compared after adjusting for baseline difference and clustering factors. Discussion: This trial will be the first study in Australian general practice and one of few international studies to evaluate the impact of implementing CVAR assessment and management. Results of this study will help improve the primary prevention of cardiovascular disease and inform guidelines for clinical practice and the implementation of other health initiatives. © 2009 Mosby, Inc.

Objectives: Despite the need to develop effective strategies for improving health literacy for weight management in non-English speaking migrants, the evidence about the impact of ethnicity on health literacy remains poorly understood. This review sought to understand how ethnicity modifies the effect of interventions aimed at improving health literacy for weight management in non-English speaking migrants and whether these interventions impact on behavioural and physiological risk factors. Design: We conducted a systematic review. Major electronic databases were searched using keywords in various combinations. Eligibility criteria included quantitative and qualitative studies, among non-English speaking adult migrants, who were overweight or obese, in primary health care. Results: A total of 10 studies met the inclusion criteria (four quantitative and six qualitative studies) mostly with Hispanic population in the USA and none of high quality. The mean age of the participants was 45. BMI and indicators of social status, including income and education were not consistently reported in all the studies. Conclusion: Interventions that are culturally adapted to their target group, incorporate both nutrition and physical activity education, and delivered by a multidisciplinary tea, were proven to be successful in improving health literacy and weight in overweight or obese non-English speaking migrants. It was difficult to tease out the effect of ethnicity on these interventions. Ethnicity was found to be a barrier and facilitator for improving health literacy for weight management by shaping beliefs, attitudes, and understanding around weight management in this group. More research is needed to develop evidence-based interventions to improve health literacy and weight in non-English speaking migrants.

liver fat, and the addition of common CVD blood markers (TG, HDL, hsCRP) increased the predictive power to 43%. However, addition of the novel Omega-3 Index, and red blood cell n-6/n-3 ratio to the model did not meaningfully or statistically improve the prediction of liver fat. Conclusions: Against our hypothesis, the Omega3 Index was positively correlated with liver fat. NAFLD is an important risk factor for CVD, and further research is needed to test the predictive capacity of the Omega-3 Index in higher risk populations. In healthy overweight/obese adults, simple routine clinical measurements are useful for predicting those at increased risk of NAFLD.

to the participants’ perception and use of the Australian environment. Assimilated participants were inclined to engage the Australian environment as one conducive to physical activity and health. Ultimately, it was found that the physical environment contributes to the relationship between the pattern of acculturation and obesity in migrant populations. On this basis, suggestions for modifications to the migrant obesity theoretical model are considered.

Background and aims: Early childhood is an important period for establishing behaviours that will affect weight gain and health across the life course. Children from disadvantaged families including those from low socio-economic backgrounds and indigenous families have significantly higher rates of obesity, making early intervention particularly important in these groups. Little is known however, about the most effective intervention approaches in these populations. This study will report the findings of a systematic review of the effectiveness of interventions to promote healthy weight gain in children 0—5 years from socioeconomically disadvantaged and indigenous families. Methods: Searches of major electronic databases were undertaken to identify intervention studies promoting healthy weight gain in children aged 0—5 years from low socio-economic and indigenous families. Articles published in the last 20 years reporting on feeding practices, anthropometric, diet, physical activity or sedentary behaviour outcomes were included. A total of 4144 unique citations were identified and a screening of titles, abstracts resulted in 83 papers to be reviewed to identify studies meeting the eligibility criteria. Data on included studies are to be extracted by one reviewer and verified by a second reviewer. Internal and external validity will also be assessed using standard quality rating tools. Results: The review will assess overall effectiveness of the interventions using meta-analysis (if possible) and narrative synthesis. The review will also report on the reach of the interventions, the most important intervention targets, the effectiveness of various intervention strategies and delivery modes as well as the generalizability of the studies. Significance: This review will provide important new information about the best bets in obesity prevention interventions for socioeconomically disadvantaged and indigenous families, as well as identifying key gaps in knowledge to guide future research. To be considered for ‘late breaking abstracts’ with results to be updated.
