Healthy rural hearts: The feasibility of a telehealth nutrition randomised controlled trial for rural people at risk of cardiovascular disease.

INTRODUCTION: Improving dietary patterns using medical nutrition therapy delivered via telehealth could make an effective contribution to reducing cardiovascular disease burden in rural Australia. However, it is important that medical nutrition therapy programmes are developed in collaboration with rural stakeholders, to increase feasibility for the rural context and the likelihood of successful implementation. The aim of this study was to evaluate the preliminary feasibility outcomes of integration (implementation), practicality, acceptability, demand, and preliminary effectiveness at the 3-month timepoint of the Healthy Rural Hearts randomised control trial. METHODS: Feasibility measures were collected from participants in the Healthy Rural Hearts medical nutrition therapy trial. Study participants were patients from eligible primary care practices who had been assessed by their general practitioner as being at moderate to high risk of developing cardiovascular disease in the next five years. The sample in this analysis includes those who had completed the first 3-months of the study. Feasibility outcomes were measured over the first 3-months of the trial intervention. A process evaluation survey was used to collect measures relating to intervention implementation, practicality, acceptability, and demand. Completion rates of the Australian Eating Survey Heart version, Personalised Nutrition Questionnaire, pathology tests and telehealth medical nutrition therapy consultations delivered by Accredited Practising Dietitians were also used to measure intervention practicality. Preliminary effectiveness was evaluated by comparing the intervention group's dietary change, measured using Australian Eating Survey Heart with data from the control group. RESULTS: A total of 105 participants (75 intervention, 30 control participants) were eligible for inclusion in analysis. Attendance rates at the first 3-months of dietitian consultations ranged from 94.7% to 89.3% between the first and 3-month consultations, and most participants were able to complete the Australian Eating Survey Heart and Personalised Nutrition Questionnaire prior to their initial consultation [Australian Eating Survey Heart (n = 57, 76%) and Personalised Nutrition Questionnaire (n = 61, 81.3%)] and the Australian Eating Survey Heart prior to their 3-month consultation (n = 52, 69.3%). Of the participants who completed a pathology test at the 3-month time-point (n = 54, 72%), less than half were able to do so prior to their dietitian consultation (n = 35, 46.7%). Of the 75 intervention participants, 28 (37.3%) completed the process evaluation survey. Intervention participants ranked acceptability of the Healthy Rural Hearts intervention highly (mean rank out of 10 = 9.5, SD 1.9), but provided mixed responses on whether they would access the intervention outside of the study (mean rank out of 10 = 6.0, SD 3.5). There were statistically significant increases in percentage total energy intake derived from nutrient-dense core foods compared to the control group (p ≤ 0.05). DISCUSSION: The positive findings related to acceptability and implementation outcomes suggest that the Healthy Rural Hearts intervention was acceptable, practical, and able to be implemented within this population living in rural NSW. This, combined with the small to medium effect size in the proportion of total energy derived from nutrient-dense core foods compared to the control group indicates that long-term intervention effectiveness on other cardiovascular disease outcomes is important to evaluate in the future.

Increasing food insecurity severity is associated with lower diet quality.

OBJECTIVE: Food insecurity may reduce diet quality, but the relationship between food insecurity severity and diet quality is under-researched. This study aimed to examine the relationship between diet quality and severity of household food insecurity. DESIGN: A cross-sectional, online survey used the United States Department of Agriculture Household Food Security Six-item Short Form to classify respondents as food secure or marginally, moderately or severely food insecure. The Australian Recommended Food Score (ARFS; scored 0­73) determined diet quality (ARFS total and sub-scale scores). Survey-weighted linear regression (adjusted for age, sex, income, education, location and household composition) was conducted. SETTING: Tasmania, Australia. PARTICIPANTS: Community-dwelling adults (aged 18 years and over). RESULTS: The mean ARFS total for the sample (n 804, 53 % female, 29 % aged > 65 years) was 32·4 (sd = 9·8). As the severity of household food insecurity increased, ARFS total decreased. Marginally food-insecure respondents reported a mean ARFS score three points lower than food-secure adults (B = ­2·7; 95 % CI (­5·11, ­0·34); P = 0·03) and reduced by six points for moderately (B = ­5·6; 95 % CI (­7·26, ­3·90); P < 0·001) and twelve points for severely food-insecure respondents (B = ­11·5; 95 % CI (­13·21, ­9·78); P < 0·001). Marginally food-insecure respondents had significantly lower vegetable sub-scale scores, moderately food-insecure respondents had significantly lower sub-scale scores for all food groups except dairy and severely food-insecure respondents had significantly lower scores for all sub-scale scores. CONCLUSIONS: Poorer diet quality is evident in marginally, moderately and severely food-insecure adults. Interventions to reduce food insecurity and increase diet quality are required to prevent poorer nutrition-related health outcomes in food-insecure populations in Australia.

Development of a Scoring Tool for Australian Rural Food Retail Environments.

Current tools scoring the healthiness of food retail outlets do not reflect outlets found in rural locations. This study aimed to adapt pre-existing Australian scoring tools to represent non-metropolitan areas. Rural nutrition experts were identified, and a modified Delphi technique was used to adapt two pre-existing, food-scoring tools in five iterative stages. Stages included identifying all relevant outlets, providing a description and score for each, ensuring consistency between outlet scores and pre-existing, metro-centric tools, and providing instructions for correct use. Six rural nutrition experts were identified and engaged in the modified Delphi technique. The final tool consisted of 12 categories of food outlets and listed 35 individual outlets. Consistent with pre-existing Australian tools, scores ranged from +10 to -10 and included descriptions reflective of rural retail outlets. Scores were based on whether the majority of foods offered within the outlet were consistent with foods recommended in national health guidelines. The developed tool was designed to accommodate the diverse nature of food retail outlets found in non-metropolitan areas. This study assists in explaining the link between the food environment and health in populations living rurally.

Delivery of telehealth nutrition and physical activity interventions to adults living in rural areas: a scoping review.

BACKGROUND: Lifestyle behaviours related to smoking, alcohol, nutrition, and physical activity are leading risk factors for the development of chronic disease. For people in rural areas, access to individualised lifestyle services targeting behaviour change may be improved by using telehealth. However, the scope of literature investigating telehealth lifestyle behaviour change interventions for rural populations is unknown, making it difficult to ascertain whether telehealth interventions require adaptation for rural context via a systematic review. This scoping review aimed to address this gap, by mapping existing literature describing telehealth lifestyle interventions delivered to rural populations to determine if there is scope for systematic review of intervention effectiveness in this research topic. METHODS: The PRISMA extension for scoping review checklist guided the processes of this scoping review. A search of eight electronic databases reported in English language until June 2023 was conducted. Eligible studies included adults (18 years and over), who lived in rural areas of high-income countries and undertook at least one synchronous (video or phone consultation) telehealth intervention that addressed either addictive (smoking or alcohol), or non-addictive lifestyle behaviours (nutrition or physical activity). Studies targeting addictive and non-addictive behaviours were separated after full text screening to account for the involvement of addictive substances in smoking and alcohol studies that may impact behaviour change interventions described. Studies targeting nutrition and/or physical activity interventions are presented here. RESULTS: The search strategy identified 17179 citations across eight databases, with 7440 unique citations once duplicates were removed. Full texts for 492 citations were retrieved and screened for inclusion with 85 publications reporting on 73 studies eligible for data extraction and analysis. Of this, addictive behaviours were comprised of 15 publications from 13 studies. Non-addictive behaviours included 70 publications from 58 studies and are reported here. Most interventions were delivered within the United States of America (n = 43, 74.1%). The most common study design reported was Randomised Control Trial (n = 27, 46.6%). Included studies involved synchronous telehealth interventions targeting nutrition (11, 18.9%), physical activity (5, 8.6%) or nutrition and physical activity (41, 70.7%) and were delivered predominately via videoconference (n = 17, 29.3%). CONCLUSIONS: Despite differences in intervention characteristics, the number of randomised control trials published suggests sufficient scope for future systematic reviews to determine intervention effectiveness related to nutrition and physical activity telehealth interventions for rural populations. TRIAL REGISTRATION: The scoping review protocol was not pre-registered.

Rural nutrition and dietetics research-Future directions.

AIM: The aim of this study was to summarise key evidence from recent Australian rural nutrition research and provide recommendations for future nutrition and dietetics research with rural communities. CONTEXT: Clear evidence demonstrates that diet plays a role in the health gap between rural and metropolitan Australia. Despite the opportunity to address the health of rural Australians through better nutrition, alarmingly low investment in nutrition and dietetics research has occurred historically, and over the past decade. APPROACH: A review of the evidence was undertaken by rural nutrition and dietetics leaders to provide a commentary piece to inform future rural nutrition research efforts. CONCLUSION: Establishing strong, collaborative place-based nutrition and dietetics research teams are necessary to combat the significant gaps in the scientific knowledge of solutions to improve nutrition in rural Australia. Further, dieticians and nutritionists who live in and understand the rural contexts are yet to be fully harnessed in research, and better engaging with these professionals will have the best chance of successfully addressing the nutrition-related disease disparity between rural and metropolitan Australia.

Dietary patterns in rural and metropolitan Australia: a cross-sectional study exploring dietary patterns, inflammation and association with cardiovascular disease risk factors.

OBJECTIVES: This study sought first to empirically define dietary patterns and to apply the novel Dietary Inflammation Score (DIS) in data from rural and metropolitan populations in Australia, and second to investigate associations with cardiovascular disease (CVD) risk factors. DESIGN: Cross-sectional study. SETTING: Rural and metropolitan Australia. PARTICIPANTS: Adults over the age of 18 years living in rural or metropolitan Australia who participated in the Australian Health survey. PRIMARY OUTCOMES: A posteriori dietary patterns for participants separated into rural and metropolitan populations using principal component analysis. SECONDARY OUTCOMES: association of each dietary pattern and DIS with CVD risk factors was explored using logistic regression. RESULTS: The sample included 713 rural and 1185 metropolitan participants. The rural sample was significantly older (mean age 52.7 compared with 48.6 years) and had a higher prevalence of CVD risk factors. Two primary dietary patterns were derived from each population (four in total), and dietary patterns were different between the rural and metropolitan areas. None of the identified patterns were associated with CVD risk factors in metropolitan or rural areas, aside diet pattern 2 being strongly associated with from self-reported ischaemic heart disease (OR 13.90 95% CI 2.29 to 84.3) in rural areas. There were no significant differences between the DIS and CVD risk factors across the two populations, except for a higher DIS being associated with overweight/obesity in rural areas. CONCLUSION: Exploration of dietary patterns between rural and metropolitan Australia shows differences between the two populations, possibly reflective of distinct cultures, socioeconomic factors, geography, food access and/or food environments in the different areas. Our study provides evidence that action targeting healthier dietary intakes needs to be tailored to rurality in the Australian context.

HealthyRHearts - reducing cholesterol in rural adults via telehealth-based medical nutrition therapy: protocol for a cluster randomised controlled trial.

BACKGROUND: Few randomised controlled trials specifically focus on prevention in rural populations. Cardiovascular disease (CVD) contributes to approximately one quarter of deaths in Australia. Nutrition is a key component affecting many risk factors associated with CVD, including hypercholesterolaemia. However, access to medical nutrition therapy (MNT) is limited for people living in rural areas, potentially exacerbating inequities related to health outcomes. Telehealth services present an opportunity to improve MNT access and address healthcare disparities for rural populations. The present study aims to evaluate feasibility, acceptability, and cost-effectiveness of a telehealth MNT CVD intervention program in lowering CVD risk over 12-months in regional and rural primary health care settings. METHODS/DESIGN: A cluster randomised controlled trial set in rural and regional general practices in NSW, Australia, and their consenting patients (n = 300 participants). Practices will be randomised to either control (usual care from their General Practitioner (GP) + low level individualised dietetic feedback) or intervention groups (usual care from their GP + low level individualised dietetic feedback + telehealth MNT intervention). Telehealth consultations will be delivered by an Accredited Practising Dietitian (APD), with each intervention participant scheduled to receive five consultations over a 6-month period. System-generated generic personalised nutrition feedback reports are provided based on completion of the Australian Eating Survey - Heart version (AES-Heart), a food frequency questionnaire. Eligible participants must be assessed by their GP as at moderate (≥ 10%) to high (> 15%) risk of a CVD event within the next five years using the CVD Check calculator and reside in a regional or rural area within the Hunter New England Central Coast Primary Health Network (HNECC PHN) to be eligible for inclusion. Outcome measures are assessed at baseline, 3, 6 and 12 months. The primary outcome is reduction in total serum cholesterol. Evaluation of the intervention feasibility, acceptability and cost-effective will incorporate quantitative, economic and qualitative methodologies. DISCUSSION: Research outcomes will provide knowledge on effectiveness of MNT provision in reducing serum cholesterol, and feasibility, acceptability, and cost-effectiveness of delivering MNT via telehealth to address CVD risk in rural regions. Results will inform translation to health policy and practice for improving access to clinical care in rural Australia. TRIAL REGISTRATION: This trial is registered at anzctr.org.au under the acronym HealthyRHearts (Healthy Rural Hearts), registration number ACTRN12621001495819.

Developing a telehealth medical nutrition therapy (MNT) service for adults living in rural Australia at risk of cardiovascular disease: An intervention development study.

BACKGROUND: Receiving medical nutrition therapy (MNT) from an accredited practising dietitian (APD) can reduce diet-related cardiovascular disease (CVD) risk factors. However, people living in rural areas of Australia experience barriers to accessing dietitians because of their remote location. Telehealth has the potential to improve dietetic access in rural areas; however, there is limited research into the development and delivery of telehealth MNT interventions specific to these areas. The present study describes the development of the Healthy Rural Hearts (HealthyRHearts) telehealth MNT intervention, which was developed as a part of the HealthyRHearts randomised control trial, set in primary care practices in rural areas of the Hunter New England and Central Coast Primary Health Network. The aim of HealthyRHearts is to improve diet-related risk factors for CVD in rural adults at moderate to high CVD risk using a telehealth MNT intervention delivered by an APD. METHODS: The study describes the development of the HealthyRHearts telehealth MNT intervention, using the 14-item GUIDance for rEporting of intervention Development (GUIDED) checklist and the Template for Intervention Description and Replication (TIDieR) framework to guide description. RESULTS: HealthyRHearts is a complex intervention that aims to translate a telehealth MNT intervention for CVD prevention into rural and remote primary care settings. The intervention is designed to be implemented across multiple sites of varying characteristics and needs, with the ability to accommodate individual complexities within the rural context and target population. Participants are adults aged 45-75 years who are assessed as moderate to high risk of CVD by their general practitioner (GP). Consenting participants are referred to the intervention by their GPs and receive five telehealth MNT consultations with an APD over 6-months. APDs are trained in the intervention protocol including intervention materials, resources and behaviour change counselling strategies. CONCLUSION: Using the GUIDED and TIDieR frameworks to guide description of the HealthyRHearts intervention development process facilitates detailed description of decision-making pathways for each element of the intervention design. The comprehensive description of the intervention development process for HealthyRHearts is intended to facilitate replication, iteration and optimisation of the intervention for rural contexts.

Omega-3 Fatty Acids during Pregnancy in Indigenous Australian Women of the Gomeroi Gaaynggal Cohort.

Higher dietary intakes of Omega-3 long-chain polyunsaturated fatty acids (n-3 LC-PUFAs) have been linked to lower rates of preterm birth and preeclampsia. The aim of this analysis was to describe dietary intake and fractions of red blood cell (RBC) membrane LC-PUFAs during pregnancy in a cohort of Indigenous Australian women. Maternal dietary intake was assessed using two validated dietary assessment tools and quantified using the AUSNUT (Australian Food and Nutrient) 2011-2013 database. Analysis from a 3-month food frequency questionnaire indicated that 83% of this cohort met national n-3 LC-PUFA recommendations, with 59% meeting alpha-linolenic acid (ALA) recommendations. No nutritional supplements used by the women contained n-3 LC-PUFAs. Over 90% of women had no detectable level of ALA in their RBC membranes, and the median Omega-3 Index was 5.5%. This analysis appears to illustrate a decline in concentrations of eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA) across gestation in women who had preterm birth. However, there was no visible trend in LC-PUFA fractions in women who experienced hypertension during pregnancy. Further research is needed to better understand the link between dietary intake of n-3 LC-PUFA-rich foods and the role of fatty acids in preterm birth and preeclampsia.

The effect of a game-based mobile app 'MyHeartMate' to promote lifestyle change in coronary disease patients: a randomized controlled trial.

Aims: Secondary prevention reduces coronary heart disease (CHD) progression. Traditional prevention programs including cardiac rehabilitation are under-accessed, which smartphone apps may overcome. To evaluate the effect of a game-based mobile app intervention (MyHeartMate) to improve cardiovascular risk factors and lifestyle behaviours. Methods and results: Single-blind randomized trial of CHD patients in Sydney, 2017-2021. Intervention group were provided the MyHeartMate app for 6 months. Co-designed features included an avatar of the patient's heart and tokens earned by risk factor work (tracking, challenges, and quizzes). The control group received usual care. Primary outcome was self-reported physical activity [metabolic equivalents (METs), Global Physical Activity Questionnaire] and secondary outcomes included lipid levels, blood pressure (BP), body mass index, and smoking. Pre-specified sample size was achieved (n = 390), age 61.2 ± 11.5 years; 82.5% men and 9.2% current smokers. At 6 months, adjusted for baseline levels, the intervention group achieved more physical activity than control (median difference 329 MET mins/wk), which was not statistically significant (95% CI -37.4, 696; P = 0.064). No differences occurred between groups on secondary outcomes except for lower triglyceride levels in the intervention [mean difference -0.3 (95% CI -0.5, -0.1 mmoL/L, P = 0.004)]. Acceptability was high: 94.8% of intervention participants engaged by tracking exercise or BP and completing missions; 26.8% continued to engage for ≥30 days. Participants (n = 14) reported the app supported tracking behaviours and risk factors, reinforcing and improving self-care confidence, and decreasing anxiety. Conclusion: A game-based app proved highly acceptable for patients with CHD but did not improve risk factors or lifestyle behaviours other than triglyceride levels.

Modifiable Risk Factors for Cardiovascular Disease among Women with and without a History of Hypertensive Disorders of Pregnancy.

Cardiovascular disease (CVD) is the leading cause of morbidity and mortality in women. Hypertensive disorders of pregnancy (HDP) affect 5−10% of pregnancies worldwide, and are an independent risk factor for CVD. A greater understanding of the rates of modifiable CVD risk factors in women with a history of HDP can inform CVD prevention priorities in this group. The aim of this study was to understand the rates of individual and multiple modifiable risk factors for CVD (body mass index, fruit and vegetable intake, physical activity, sitting time, smoking, alcohol consumption and depressive symptoms) among women with a history of HDP, and assess whether they differ to women without a history of HDP. This study is a cross-sectional analysis of self-reported data collected for the Australian Longitudinal Study of Women's Health (ALSWH). The sample included 5820 women aged 32−37 years old, who completed survey 7 of the ALSWH in 2015. Women with a history of HDP had a higher multiple CVD modifiable risk factor score compared to those without HDP (mean (SD): 2.3 (1.4) vs. 2.0 (1.3); p < 0.01). HDP history was significantly associated with a higher body mass index (p < 0.01), high-risk alcohol consumption (p = 0.04) and more depressive symptoms (p < 0.01). Understanding that women with a history of HDP have higher CVD risk factors, specifically body mass index, alcohol consumption and depressive symptoms, allows clinicians to provide appropriate and tailored CVD interventions for this group of women.

Effectiveness and reporting of nutrition interventions in cardiac rehabilitation programmes: a systematic review.

AIMS: Dietary modification is essential for the secondary prevention of cardiovascular disease. However, there are limited published evidence syntheses to guide practice in the cardiac rehabilitation (CR) setting. This systematic review's objective was to assess effectiveness and reporting of nutrition interventions to optimize dietary intake in adults attending CR. METHODS AND RESULTS: Randomized controlled trials (RCTs) of nutrition interventions within CR were eligible for inclusion and had to have measured change in dietary intake. MEDLINE, Embase, Emcare, PsycINFO, CINAHL, Scopus, and The Cochrane Library were searched from 2000 to June 2020, limited to publications in English. Evidence from included RCTs was synthesized descriptively. The risk of bias was assessed using the Cochrane Risk of Bias 2 tool. This review is registered on PROSPERO; CRD42020188723. Of 13 048 unique articles identified, 11 were eligible. Randomized controlled trials were conducted in 10 different countries, included 1542 participants, and evaluated 29 distinct dietary intake outcomes. Five studies reported statistically significant changes in diet across 13 outcomes. Most nutrition interventions were not reported in a manner that allowed replication in clinical practice or future research. CONCLUSION: There is a gap in research testing high-quality nutrition interventions in CR settings. Findings should be interpreted in the light of limitations, given the overall body of evidence was heterogenous across outcomes and study quality; 6 of 11 studies were conducted more than 10 years old. Future research should investigate strategies to optimize and maintain nutrition improvements for patients attending CR. REGISTRATION: PROSPERO; CRD42020188723.

Do sauces, condiments and seasonings contribute important amounts of nutrients to Australian dietary intakes?

BACKGROUND: Dietary assessment commonly focuses on particular foods/food groups as indicators of overall dietary intake. Accompaniments such as sauces are not often a focus. The present study describes daily intakes of sauces, condiments and seasonings (SCS) using the most recent Australian National Nutrition and Physical Activity Survey (NNPAS), as well as the contribution to total energy and selected nutrient intakes. METHODS: NNPAS dietary data were collected by one 24-h recall for 12,153 individuals aged ≥ 2 years (53% female, 29% aged 31-50 years). SCS (i.e., any food items not normally consumed as a food itself, consumed as an addition to a dish after cooking/preparation to enhance flavour) were identified/coded within the dietary data and reported in terms of how they were consumed, primary composition, and contribution to total daily energy and selected macro- and micronutrient intakes. RESULTS: Most participants (85.1%) reported consuming at least one SCS on the day of the recall (median [interquartile range], 2 [1-4]). SCS were predominantly consumed within main meals (breakfast, lunch, dinner) (73.9%), and were predominantly sugar/sugar products (e.g., white sugar) (35.0%), or fats and oils (e.g., butter) (25.9%). SCS contributed a median (interquartile range) of 3.8% (1.1-7.9) of total energy, 5.3% (0.0-15.5) of fat, 2.3% (0.1-6.6) of carbohydrate and 0.2% (0.01-1.2) of protein intake. SCS made the largest contribution towards vitamin E (females median 3.6%; males median 3.4%) and sodium intakes (females median 3.0%; males median 2.9%). CONCLUSIONS: Although SCS contribute a small proportion of total energy and nutrient intakes in the Australian population, the contribution is more substantial for some nutrients and population groups.

Communication regarding the deactivation of implantable cardioverter-defibrillators: A scoping review and narrative summary of current interventions.

OBJECTIVES: Communication about deactivation of implantable cardioverter-defibrillator (ICD) therapy at end-of-life (EoL) is a recognised issue within clinical practice. The aim of this scoping review was to explore and map the current literature in this field, with a focus on papers which implemented interventional studies. METHODS: Systematic searches of six major databases were conducted. Citations were included by four researchers according to selection criteria. Key demographic data and prespecified themes in relation to communication of ICD deactivation at EoL were extracted. RESULTS: The search found 6197 texts of which 63 were included: 39 quantitative, 14 qualitative and 10 mixed-methods. Surveys were predominantly used to gather data (n = 34), followed by interviews (n = 18) and retrospective reviews of patient records (n = 18). CONCLUSIONS: Several key gaps in the literature warrant further research. These include who is responsible for initiating ICD deactivation discussions, how clinicians should initiate and conduct these discussions, when ICD deactivations should be occurring, and family perspectives. Adequately explored themes include patient and clinician knowledge and attitudes regarding ICD deactivation at EoL. PRACTICAL IMPLICATIONS: Facilities treating patients with ICDs at EoL should consider ongoing quality improvement projects aimed at clinician education and protocol changes to improve communication surrounding EoL ICD deactivation.

Evaluating a train-the-trainer model for scaling-up Healthy Conversation Skills training: A pre-post survey using the Theoretical Domains Framework.

OBJECTIVES: Healthy Conversation Skills (HCS) training is an established method of upskilling health professionals in person-centred behaviour change communication. A Train-the-Trainer (TtT) model was adopted to scale-up delivery of HCS training. This study examined the impact of the TtT course on new Trainers' perceived barriers and enablers to delivering HCS training using the Theoretical Domains Framework (TDF). METHODS: The TtT course was delivered in 2019-2020. Pre-training (T1) and post-training (T2) surveys collected data on barriers and enablers to delivering HCS training based on 10 TDF domains. Data were summarised using descriptive statistics, and differences between pre- and post-training scores analysed using paired t-tests. RESULTS: Forty-six trainees participated, including 43 women and 10 Aboriginal people. Scores for nine domains increased post-training, including knowledge, skills, social and professional role/identity, beliefs about capabilities, intentions, goals, environmental context and resources, social influences, and behavioural regulation. Knowledge, beliefs about consequences and intentions were no longer barriers to delivering HCS training after participating in the TtT course. CONCLUSIONS: The TtT model supports new Trainers by addressing barriers to delivering HCS training. PRACTICE IMPLICATIONS: The HCS TtT model builds healthcare workforce capacity for person-centred approaches to behaviour change. The findings facilitate the refinement of the TtT course.

Testing the effectiveness of a novel, evidence-based weight management and lifestyle modification programme in primary care: the Healthy Weight Initiative.

Introduction Primary care prevention strategies that support and provide tools for general practice have the potential to slow and reverse rates of overweight and obesity. Aim To test the effectiveness of a novel 12-week, online, structured, evidence-based weight management and lifestyle modification programme in general practices. Methods Between August 2018 and March 2020, participants with a body mass index (BMI) ≥ 25 were recruited from general practices in the Hunter New England and Central Coast Primary Health Network region of Australia. Practices were randomly assigned to deliver a 'low-intensity' (LI) or 'high-intensity' (HI) variant of the programme. Practitioners were trained in programme delivery. The intervention involved weekly progress and accountability checks and scripted education sessions on evidenced-based nutrition, physical activity and lifestyle modification. The trial included follow-up evaluations at 6 and 12 months. Results In total, 695 participants were recruited from 26 practices. At the end of the 12-week programme, participants in the HI treatment arm lost an average of 3.2 kg (s.d. 3.8) and 29% (50/172) achieved clinically significant weight loss (>5% of initial body weight). Positive results were maintained at evaluations by participants in the HI treatment arm who attended, but only 31% of participants at 6 months and 21% at 12 months were followed up. Discussion Participant engagement and retention and practitioner workload burden are key factors in the design of weight management programmes in primary care. Many lessons can be obtained as a result of this trial, and programme adjustments have been identified to improve its delivery model.

Characterizing the Health of Older Rural Australians Attending Rural Events: Implications for Future Health Promotion Opportunities.

This paper describes the health of older Australians (>65 years) attending rural events to inform health promotion interventions for rural populations. This cross-sectional study collected survey data and objective health measures between 2017 and 2020 at two events held in rural New South Wales, Australia. Participants included in the analysis were adults > 65 years of age. Data included demographic and health information, anthropometric measures (height, weight, waist circumference), and dietary and physical activity data. A total of 256 people > 65 years participated. Our sample, which was mostly male (59.0%), contained people aged between 66 and 75 years (72.3%). Participants lived in either a large rural (34.0%) or small rural town (22.3%), with low levels of education (60.9% did not complete high school). Dietary quality was rated as below average. All but 17.2% of the participants reported having a health condition. The risk of a health condition was associated with increasing age, lower education, and higher waist circumference, but not remoteness. Rural events may provide an opportunity to access, engage with, and understand the health of older rural Australians, especially males. They may offer ideal contexts for health and nutrition promotion opportunities in rural areas where access to health professionals is limited.

Rural healthcare delivery and maternal and infant outcomes for diabetes in pregnancy: A systematic review.

AIM: The aim of this systematic review was to examine the literature regarding rural healthcare delivery for women with any type of diabetes in pregnancy, and subsequent maternal and infant outcomes. METHODS: Eight databases were searched in September 2020, including Medline, EMCare, CINAHL, EMBASE, Maternity and Infant Care, Cochrane, Rural and Remote Health and Aboriginal and Torres Strait Islander Health bibliography. Studies from high-income countries in rural, regional or remote areas with interventions conducted during the antenatal period were included. Intervention details were reported using the template for intervention description and replication template. Two reviewers independently assessed for risk of bias using the RoB2 and ROBINS I tools. RESULTS: Three articles met the inclusion criteria: two conducted in Australia and one in the United States. A multidisciplinary approach was reported in two of the included studies, which were modified specifically for their respective rural settings. All three studies reported rates of caesarean section, birthweight (grams) and gestational age at birth as maternal and infant outcomes. One study was considered at moderate risk of bias, and two studies were at serious risk of bias. CONCLUSION: There is a significant gap in research relating to healthcare delivery for women with diabetes in pregnancy in rural areas. This lack of research is concerning given that 19% of individuals in high-income countries reside rurally. Further research is required to understand the implications of healthcare delivery models for diabetes in pregnancy in rural areas.

Effectiveness of interventions to optimise dietary intakes in the first 1000 d of life in Indigenous children: a systematic review.

OBJECTIVE: Indigenous infants are disproportionately more likely to have negative outcomes compared to non-Indigenous infants with suboptimal nutrition in the first 1000 d playing a major role. This review aimed to systematically assess the effectiveness of interventions designed to optimise dietary intake and/or nutrition-related behaviours among Indigenous infants globally and to identify whether Indigenous populations were involved in the co-design of the intervention. DESIGN: Articles published before June 2020 that reported nutrition-related interventions and outcomes for Indigenous infants were identified from a database search. Data extracted included study aims and design, target population, geographical location, the health condition of the participants, intervention characteristics and outcomes. A narrative synthesis consisting of effects and acceptability of the interventions and involvement of participants in the study design were highlighted. SETTINGS: Population-based intervention studies that focused on improving dietary intakes and/or nutrition-related behaviours of Indigenous infants in the first 1000 d of life were included in this review. RESULTS: Of the 2784 studies identified, three studies met the inclusion criteria. These were conducted among two Indigenous tribes in Guatemala and the USA. Two studies reported the food and nutrient intake of participants with one study showing an improvement in dietary intake of the infants. Only one study reported community participation in the study design, intervention design and implementation, and acceptability of the intervention by the participants. CONCLUSION: Engaging Indigenous communities throughout the entire process of nutrition interventions could have beneficial effects through improved outcomes in the first 1000 d of life.

Current Nutrition Practice in Cardiac Rehabilitation Programs.

PURPOSE: This study sought to determine current practice regarding nutrition care within cardiac rehabilitation (CR) programs, including perceived barriers and facilitators to providing nutrition care in this setting. METHODS: A cross-sectional survey was conducted in October and November 2019. Potential participants were program coordinators, identified through the Australian Cardiovascular Health and Rehabilitation Association program directory and invited to participate via e-mail. RESULTS: Forty-nine respondents (response rate: 13%) are included in this analysis. Programs provided group (n = 42, 86%) and/or individual (n = 25, 51%) nutrition education, and most were supported by a dietitian (63%). However, the availability of dietitians and nutrition care provided at CR was variable. For example, individual education was consistently provided at 13 programs and usually by health professionals other than dietitians. Eight programs (16%) used a formal behavior change framework for nutrition care. Generally, respondents were positive about the role of nutrition; CR coordinators perceived nutrition as a valuable component of the program, and that they had good nutrition knowledge. An identified barrier was the financial resources available to support the provision of nutrition care. CONCLUSIONS: To ensure that patients receive the benefits of evidence-based nutrition care, program staff may require additional support, particularly regarding the use of evidence-based behavior change techniques. Key facilitators that may be leveraged to achieve this include the high value and priority that CR program coordinators place on nutrition care.
