Interventions to Increase Physical Activity in Community-Dwelling Older Adults in Regional and Rural Areas: A Realist Synthesis Review Protocol.

The importance of physical activity (PA) for the health and wellbeing of older adults is well documented, yet many older adults are insufficiently active. This issue is more salient in regional and rural areas, where evidence of the most critical components of interventions that explain PA participation and maintenance in older populations is sparse. This realist review will (1) systematically identify and synthesise literature on PA interventions in community-dwelling older adults in regional and rural areas, and (2) explore how and why those interventions increase PA in that population. Using a realist synthesis framework and the behaviour change wheel (BCW), context-mechanism-outcome (C-M-O) patterns of PA interventions for older adults in regional and rural areas will be synthesised. Thematic analysis will be employed to compare, contrast, and refine emerging C-M-O patterns to understand how contextual factors trigger mechanisms that influence regional and rural community-dwelling older adults' participation in PA interventions. This realist review will be the first to adopt a BCW analysis and a realist synthesis framework to explore PA interventions in community-dwelling older adults in regional and rural areas. This review will provide recommendations for evidence-based interventions to improve PA participation and adherence by revealing the important mechanisms apparent in this context.

Barriers and Facilitators to Screening for Cognitive Impairment in Australian Rural Health Services: A Pilot Study.

Australian National standards recommend routine screening for all adults over 65 years by health organisations that provide care for patients with cognitive impairment. Despite this, screening rates are low and, when implemented, screening is often not done well. This qualitative pilot study investigates barriers and facilitators to cognitive screening for older people in rural and regional Victoria, Australia. Focus groups and interviews were undertaken with staff across two health services. Data were analysed via thematic analysis and contextualized within the i-PARIHS framework. Key facilitators of screening included legislation, staff buy-in, clinical experience, appropriate training, and interorganisational relationships. Collaborative implementation processes, time, and workloads were considerations in a recently accredited tertiary care setting. Lack of specialist services, familiarity with patients, and infrastructural issues may be barriers exacerbated in rural settings. In lieu of rural specialist services, interorganisational relationships should be leveraged to facilitate referring 'outwards' rather than 'upwards'.

Exploring Telehealth Readiness in a Resource Limited Setting: Digital and Health Literacy among Older People in Rural India (DAHLIA).

An ageing population, disproportionally affecting developing countries, increases demand on healthcare systems. Digital health offers access to healthcare for older people, particularly those residing in rural areas, as is the case for 71% of older adults in India. This research examined technology uptake and digital and health literacy (eHEALS) among a sample of 150 older adults in rural Mysore and Suttur, India. The study utilised mixed-method, with descriptive analysis of quantitative data and thematic analysis of qualitative data. Low rates of digital (11%) and health literacy (3-27% across domains) were identified. Mobile phone ownership was 50%, but very few owned or used a smartphone and less than 10% used the Internet to contact health professionals. Qualitative analysis found low technology usage, driven by limited exposure and confidence in using digital devices. Barriers to usage included poor traditional literacy and physical aspects of ageing like poor vision. Social support from neighbours, family and local primary healthcare staff may enable adoption of digital health. Access to healthcare through digital means among Indian rural older adults needs to consider low rates of both digital and health literacy and leverage the value of support from family and primary healthcare providers.

How gender, education and nutrition knowledge contribute to food insecurity among adults in Australia.

Food and nutrition insecurity occurs when healthy and safe food cannot be obtained by socially acceptable means and arises as a result of complex interactions between socioeconomic and demographic determinants. These factors contribute to discrepancies in health and well-being between men and women and may also explain differential rates of food insecurity. The objectives of this cross-sectional study were to investigate the intersection between gender, education, nutrition knowledge and food security status within a high-income country context. Australian adults over 16 years of age who identified as having primary responsibility for food in their household were recruited via social media and a panel. Respondents completed a self-administered survey that included sociodemographic data, nutrition-related knowledge and food security status. Food security was measured using the Australian Household Food and Nutrition Security Scale an adapted version of the United States Department of Agriculture Household Food Security Survey. Among the 1010 survey respondents, household food insecurity (HFI) was highly prevalent (43% were food insecure, with 26% of these severely food insecure). Gender may affect associations between education, nutrition knowledge and HFI. Education was significantly associated with HFI among women but not among men. Conversely, nutrition knowledge was significantly inversely associated with food security among men but not among women. Differences in determinants of HFI exist between men and women, and programs aimed at addressing food insecurity may be more effective if tailored accordingly to account for the social and demographic factors associated with HFI.

Development and preliminary validation of a brief household food insecurity screening tool for paediatric health services in Australia.

Children from food insecure households are more likely to have substandard food and nutritional intakes, and experience developmental delays, behaviour issues and increased use of health services. In Australia, screening for household food insecurity (HFI) within health services is not undertaken routinely, limiting opportunities to optimise nutrition and healthcare. This research aimed to (a) identify the prevalence, potential determinants and outcomes of HFI among paediatric outpatients in two Queensland hospitals; and (b) identify questions suitable for screening households at risk of HFI. A cross-sectional survey collected data from caregivers of children attending paediatric appointments at two hospitals in Brisbane, Australia (n = 148). Sociodemographic, health and household-related characteristics were collected, and food security status was assessed using four HFI measures. Chi-square, independent t-tests, ANOVA and logistic regression explored associations between HFI and health-related characteristics. A potential HFI screener was identified based on the most frequently endorsed questions from any HFI measure, and its validity was assessed through calculation of sensitivity and specificity. Prevalence of HFI was 41%, with 16% experiencing very low food security. Households with a child of 'fair/poor' health had 5.59 times greater odds of being food insecure than being food secure, compared to households with a child of 'excellent/good' health (aOR 5.59, 95% CI: 1.3-23.5). HFI was also positively associated with household chaos (p = .006). A combination of two questions was identified as a possible screening tool, with a sensitivity of 96% and a specificity of 90%. This study demonstrated HFI may be highly prevalent in a paediatric outpatient population, which may result in difficulties in being able to follow nutrition prescriptions. A highly sensitive and specific two-question screening tool was identified and may assist practitioners in paediatric healthcare settings in identifying clients who are at risk of HFI.

Single-item measure of food insecurity used in the National Health Survey may underestimate prevalence in Australia.

OBJECTIVES: To compare prevalence estimates of food insecurity using a single-item measure, with three adaptations of the United States Department of Agriculture Food Security Survey Module (USDA-FSSM). METHODS: Data were collected by postal survey, from individuals aged ≥18 years from disadvantaged suburbs of Brisbane, Australia (n= 505, 53% response). Food security status was ascertained by the Australian single-item measure, and the 6-, 10- and 18-item versions of the USDA-FSSM. Prevalence estimates of food insecurity and different levels of severity of food insecurity estimated by each tool were determined. Data were analysed using McNemar's test, polychoric correlation and Rasch analyses. RESULTS: The prevalence of food insecurity was 19.5% using the single-item measure; significantly less than the 24.4%, 22.8% and 21.1% identified using the 18-item, 10-item and 6-item versions of the USDA-FSSM, respectively. Rasch analyses revealed that overall the USDA-FSSM may be a valid tool for the measurement of food insecurity within the current sample. CONCLUSION: The measure of food insecurity employed in national surveys in Australia may underestimate its prevalence and public health significance. Implications for public health: Future monitoring and surveillance efforts should seek to employ a more accurate measure as the first step in recognising the right to food for all Australians.

Preliminary validation and piloting of a comprehensive measure of household food security in Australia.

OBJECTIVE: To investigate the psychometric properties, validity and reliability of a newly developed measure of food insecurity, the Household Food and Nutrition Security Survey (HFNSS), among an Australian population. DESIGN: Cross-sectional study. SETTING: Metropolitan areas of Melbourne, Australia, identified as very high, high or medium vulnerability in the 2008 Vulnerability Assessment for Mortgage, Petrol and Inflation Risks and Expenditure index. SUBJECTS: A convenience sample of 134 adults (117 females and fifteen males, aged over 18 years). RESULTS: Rasch modelling and factor analysis identified four items for exclusion. The remaining items yielded excellent reliability among the current sample and assessed three underlying components: the adult experience of food insecurity (component one), initial/periodic changes to children's food intakes (component two) and progressive/persistent decreases in children's food intakes (component three). Compared with the widely used US Department of Agriculture Food Security Survey Module, the HFNSS identified a significantly higher proportion of food insecurity; this is likely due to the HFNSS's identification of food insecurity due to reasons other than (and including) limited financial access. CONCLUSIONS: The HFNSS may be a valid and reliable tool for the assessment of food insecurity among the Australian population and provides a means of assessing multiple barriers to food security beyond poor financial access (which has been identified as a limitation of other existing tools). Future research should explore the validity and reliability of the tool among a more representative sample, as well as specifically among vulnerable population subgroups.

Developing measures of food and nutrition security within an Australian context.

OBJECTIVE: To develop a measure of food and nutrition security for use among an Australian population that measures all pillars of food security and to establish its content validity. DESIGN: The study consisted of two phases. Phase 1 involved focus groups with experts working in the area of food security. Data were assessed using content analysis and results informed the development of a draft tool. Phase 2 consisted of a series of three online surveys using the Delphi technique. Findings from each survey were used to establish content validity and progressively modify the tool until consensus was reached for all items. SETTING: Australia. SUBJECTS: Phase 1 focus groups involved twenty-five experts working in the field of food security, who were attending the Dietitians Association of Australia National Conference, 2013. Phase 2 included twenty-five experts working in food security, who were recruited via email. RESULTS: Findings from Phase 1 supported the need for an Australian-specific tool and highlighted the failure of current tools to measure across all pillars of food security. Participants encouraged the inclusion of items to measure barriers to food acquisition and the previous single item to enable comparisons with previous data. Phase 2 findings informed the selection and modification of items for inclusion in the final tool. CONCLUSIONS: The results led to the development of a draft tool to measure food and nutrition security, and supported its content validity. Further research is needed to validate the tool among the Australian population and to establish inter- and intra-rater reliability.

Measurement of the dimensions of food insecurity in developed countries: a systematic literature review.

OBJECTIVE: Food insecurity is a salient health issue comprised of four dimensions - food access, availability, utilization and stability over time. The aim of the present study was to conduct a systematic literature review to identify all multi-item tools that measure food insecurity and explore which of the dimensions they assess. DESIGN: Five databases were searched (CENTRAL, CINAHL plus, EMBASE, MEDLINE, TRIP) for studies published in English since 1999. Inclusion criteria included human studies using multi-item tools to measure food security and studies conducted in developed countries. Manuscripts describing the US Department of Agriculture Food Security Survey Module, that measures 'food access', were excluded due to wide acceptance of the validity and reliability of this instrument. Two authors extracted data and assessed the quality of the included studies. Data were summarized against the dimensions of food insecurity. SETTING: A systematic review of the literature. SUBJECTS: The majority of tools were developed in the USA and had been used in different age groups and cultures. RESULTS: Eight multi-item tools were identified. All of the tools assessed the 'food access' dimension and two partially assessed the dimensions 'food utilization' and 'stability over time', respectively. 'Food availability' was not assessed by existing tools. CONCLUSIONS: Current tools available for measuring food insecurity are subjective, limited in scope, with a majority assessing only one dimension of food insecurity (access). To more accurately assess the true burden of food insecurity, tools should be adapted or developed to assess all four dimensions of food insecurity.
