Household Food Insecurity Negatively Impacts Diet Diversity in the Vietnamese Mekong Delta: A Cross-Sectional Study.

Healthy, diverse diets are vital for life. In low/middle-income countries, however, the focus is more on food quantity rather than diet quality. This study assessed household diet diversity (HDD) in the Vietnamese Mekong Delta and its associations with household food insecurity (HFI) and household food availability (HFA) controlling for socioeconomic factors. Primary food-preparers in 552 randomly selected households in two rural provinces were interviewed about socioeconomic factors, HDD, HFI, and HFA. More than 80% of households predominantly consumed energy-dense foods, whereas less than 20% consumed nutrient-dense foods. Lower HDD was associated with HFI, lower HFA, for the Khmer ethnic minority, and low livelihood capitals (landlessness, low expenditure, debt) and low utensil scores. The study highlighted the need to provide improved food and nutrition policies that increase availability and access to diverse and healthy foods as well as reduce poverty and increase incomes for at-risk rural and ethnic minority groups.

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.

Adaptation and evaluation of a nutrition and physical activity program for early childhood education settings in Aboriginal and Torres Strait Islander communities in remote Far North Queensland.

ISSUE ADDRESSED: Good nutrition, physical activity and adequate sleep are essential for the healthy growth and development of young children. Due to complex cultural, historical, social factors, Aboriginal and Torres Strait Islander children face additional challenges to optimal health, particularly in remote areas of Australia. 'Learning, Eating, Active Play and Sleep' (LEAPS) was a Queensland-wide professional development program designed to support early childhood education and care (ECEC) educators to implement and reinforce healthy nutrition and physical activity in their services. This article describes the adaptation, implementation and evaluation of LEAPS for remote ECEC settings in Cape York. METHODS: An Aboriginal and Torres Strait Islander Reference Group was commissioned to provide advice about the appropriateness of the existing program for Aboriginal and Torres Strait Islander ECEC settings. Based on the advice of the Reference Group, the program was adapted for use in Cape York and was evaluated using the RE-AIM framework and a combination of data sources. Quantitative data provided information about changes to participant knowledge and confidence regarding nutrition and physical activity and in-depth interviews allowed further insights into enablers and challenges for successful program implementation. CONCLUSION: A tailored LEAPS program increased participants' knowledge and confidence regarding nutrition and physical activity in ECEC settings. The importance of community consultation, building relationships and face-to-face delivery of training were highlighted as key enablers. The evaluation identified a number of challenges relating to competing priorities, limited support for ongoing implementation and adoption of improved practices. SO WHAT?: Poor nutrition and growth in children in remote Aboriginal and Torres Strait Islander communities indicates the need for the ongoing commitment to and investment in nutrition and physical activity across a range of community settings. To achieve success, this requires a dedicated preventative health workforce supporting evidence-informed, coordinated programs driven by community priorities and developed via community development approaches.

Meat, Masculinity, and Health for the "Typical Aussie Bloke": A Social Constructivist Analysis of Class, Gender, and Consumption.

Food choice is complex and influenced by a range of social, environmental, structural, and individual factors. Poor diet is one of the major contributors to the burden of disease, in particular for men who habitually have lower intakes of fruits and vegetables and higher intakes of meat. Food choice has been linked to the expression of masculine identities. This research used a Bourdieusian framework to explore the influential drivers of young Australian men's eating habits based on occupational groupings. Twenty men aged 19-30 years participated in in-depth semistructured interviews. Analysis used a grounded theory, social constructivist approach and identified five themes: performative masculinities and meat; meat cuts across social class; the influence of masculine autonomy on dietary choice; women protecting Australian men's health; and the role of environmental and structural barriers. These results indicated that habitus remains a useful conceptual framework to explain the results, and cultural capital is reinforced as a phenomenon. Occupation and gender appear to no longer be primary drivers of food choice in this group of men. Rather there is a shift toward an understanding of multiple masculinities and the development of microcultures with interactions between structure and agency. Meat still features in the food world of Australian men, but there are shifts to deprioritize its importance. There needs to be a more nuanced understanding of the importance of autonomy and control as well as the role of women in relation to men's dietary intakes and how this can be harnessed for positive dietary change.

'Back to Life'-Using knowledge exchange processes to enhance lifestyle interventions for liver transplant recipients: A qualitative study.

AIM: Interventions to prevent excessive weight gain after liver transplant are needed. The purpose of the present study was to enhance a specialist post-transplant well-being program through knowledge exchange with end-users. METHODS: The study used an interactive process of knowledge exchange between researchers, clinicians and health system users. Data were collected as focus groups or telephone interviews and underwent applied thematic analysis. RESULTS: There were 28 participants (age 24-68 years; 64% male). The results identified experiences that may influence decisions around health behaviours during the course of transplant recovery. Three over-arching themes were identified that impact on liver transplant recipients post-transplant health behaviours. These include (i) Finding a coping mechanism which highlighted the need to acknowledge the significant emotional burden of transplant prior to addressing long-term physical wellness; (ii) Back to Life encompassing the desire to return to employment and prioritise family, while co-ordinating the burden of ongoing medical monitoring and self-management and (iii) Tailored, Personalised Care with a preference for health care delivery by transplant specialists via a range of flexible eHealth modalities. CONCLUSIONS: This person-centred process of knowledge exchange incorporated experiences of recipients into service design and identified life priorities most likely to influence health behaviours post-transplant. Patient co-creation of services has the potential to improve the integration of knowledge into health systems and future directions will require evaluation of effectiveness and sustainability of patient-centred multidisciplinary service development.

Moderation of a foodservice assessment artefact in nutrition and dietetics programs.

AIM: Foodservice is a key component of dietetics education and practice internationally yet benchmarks for competency are limited. This study sought to review and moderate an assessment artefact of foodservice work integrated learning (WIL) to develop a shared understanding of one tool which may be used in a suite of evidence to demonstrate competence. METHODS: The foodservice curricula and assessment artefacts were described for the foodservice program at each of four participating universities. An assessment artefact from WIL, the report, was identified as an indicator of foodservice competence common to each program. Each university provided four purposively sampled WIL reports, assessed in duplicate by two academics from other participating universities using the corresponding university assessment rubric. Collated assessment results, along with the original assessment, were presented back to assessors. A semi-structured group discussion explored variations in assessment results, factors influencing decisions, and potential changes needed for assessment documentation. RESULTS: There was variation in assessment outcomes between independent assessors. In some instances assessors did not consistently deliver the same assessment outcome, nor rank students in sequential order of performance. This variation was less where an absolute ranking of satisfactory/unsatisfactory was applied. The assessor discussion revealed three key concepts: importance of understanding the project scope; challenges which influence assessment decision making; importance of understanding the broader program of assessment. CONCLUSIONS: Assessment inconsistencies emphasise the importance of multiple assessors and assessment artefacts across a programmatic assessment model, and the need for a clear understanding of competence in nutrition and dietetics.

Dietetics students' construction of competence through assessment and placement experiences.

AIM: Competency standards are widely adopted as a framework to describe standards of performance required in the workplace. Little is known, however, about how students construct competence. This qualitative study aimed to explore how dietetics students ready to graduate construct the concept of competence and the role of assessment in developing professional competence. METHODS: A qualitative description was used to gather data from a convenience sample of students ready to graduate from universities with accredited dietetics programs across Australia (10 out of 15 at the time of the study). A total of 11 focus groups were conducted to explore perspectives of competence and experiences of 'competency-based' assessment. Data were audio-recorded, transcribed and analysed using a thematic analysis approach. RESULTS: A total of 81 (n = 81) participants across 10 universities representing 22% of total students participated in the focus groups. Themes revealed that: (i) there is no shared understanding of competence; (ii) current work placement experiences may not reflect current standards or workforce needs; (iii) assessment approaches may not fully support the development of competence; and (iv) the competent performance of supervising dietitians/clinical educators in the workplace influences the construction of competence. CONCLUSIONS: There is a need to work towards a shared understanding of dietetic entry-level competence in the profession. 'Work-based' learning experiences may need to be modified to ensure students meet current competency standards. Practitioners involved in student supervision need to acknowledge the influential role they have in the development of the future workforce.

Dietary patterns of Australian children at three and five years of age and their changes over time: A latent class and latent transition analysis.

Consuming a healthy diet characterised by a variety of nutritious foods is essential for promoting and maintaining health and wellbeing, yet the diets of Australian children continue to fall well short of national healthy eating recommendations. This research endeavours to identify patterns of dietary intake in Australian children at three and five years of age and investigate associations between early childhood dietary patterns and socio-economic and demographic indicators and Body Mass Index (BMI), as well as identify changes in children's dietary patterns over time. Cross-sectional dietary patterns were derived for 1565 and 631 children aged three and five years, respectively using Latent Class Analysis (LCA), with changes over time analysed with Latent Transition Analysis (LTA). Demographic variables of interest included child sex, parental age, family status, and use of childcare services and socio-economic variables included education, income and employment status. Three patterns of dietary intake were identified at three years (Highly Unhealthy, Healthier and Moderately Unhealthy) and two patterns at five years (Unhealthy and Healthier). Children with younger mothers, working mothers, fathers with a higher BMI and living in a two-carer household were more likely to have unhealthy eating patterns at three years, and children with working mothers and living in a two-carer household were more likely to have unhealthy patterns of dietary intake at five years. Approximately one eighth of the sample transitioned from the healthier to unhealthy pattern of dietary intake from three to five years. The quality of Australian children's diets appears to be declining through the early childhood years, continuing to highlight the importance of nutrition policies and interventions targeted towards the early years of life.

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.

Validity of four nutritional screening tools against subjective global assessment for inpatient adults in a low-middle income country in Asia.

BACKGROUND/OBJECTIVES: Hospital malnutrition is a common problem worldwide. This study aims to assess the validity of widely used nutritional screening tools for hospitalized adults in acute care settings in Ho Chi Minh City, Vietnam. SUBJECTS/METHODS: Participants in this study were 693 adult patients from six general public hospitals, in a multi-center survey undertaken in April and May, 2016. The criterion validity of the Malnutrition Screening Tool (MST), Malnutrition Universal Screening Tool (MUST), Nutrition Risk Screening (NRS-2002) and Mini Nutrition Assessment-Short Form (MNA-SF), modified MST (MST combined with low BMI), and BMI as independent tools were assessed using Subjective Global Assessment (SGA) or low BMI (<18.5 kg/m2) as the reference method. Area under curve (AUC), sensitivity, specificity, positive predictive value (PPV), and negative predictive value (NPV) were calculated using the ROC curve method to determine the validity of screening tools. RESULTS: NRS-2002, modified MST (MST + low BMI), MUST, and BMI at 21 kg/m2 showed moderate/fair validity compared to the reference method (SGA or BMI). MST alone and MNA-SF showed poor validity due to low sensitivity (41.8 and 35.0% for MST and MNA-SF, respectively). CONCLUSIONS: Based on specificity and sensitivity, the first choice for the most appropriate screening tool for use in Vietnam is the NRS-2002, following by the MST + BMI, MUST, and BMI alone at the cut-off value of 21 kg/m2. Further investigation on the feasibility and acceptability are required to determine the most appropriate screening tools for use within the Vietnamese context.

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.

Exploring the influence of local food environments on food behaviours: a systematic review of qualitative literature.

OBJECTIVE: Systematic reviews investigating associations between objective measures of the food environment and dietary behaviours or health outcomes have not established a consistent evidence base. The present paper aims to synthesise qualitative evidence regarding the influence of local food environments on food and purchasing behaviours. DESIGN: A systematic review in the form of a qualitative thematic synthesis. SETTING: Urban localities. SUBJECTS: Adults. RESULTS: Four analytic themes were identified from the review including community and consumer nutrition environments, other environmental factors and individual coping strategies for shopping and purchasing decisions. Availability, accessibility and affordability were consistently identified as key determinants of store choice and purchasing behaviours that often result in less healthy food choices within community nutrition environments. Food availability, quality and food store characteristics within consumer nutrition environments also greatly influenced in-store purchases. Individuals used a range of coping strategies in both the community and consumer nutrition environments to make optimal purchasing decisions, often within the context of financial constraints. CONCLUSIONS: Findings from the current review add depth and scope to quantitative literature and can guide ongoing theory, interventions and policy development in food environment research. There is a need to investigate contextual influences within food environments as well as individual and household socio-economic characteristics that contribute to the differing use of and views towards local food environments. Greater emphasis on how individual and environmental factors interact in the food environment field will be key to developing stronger understanding of how environments can support and promote healthier food choices.

Playing the policy game: a review of the barriers to and enablers of nutrition policy change.

OBJECTIVE: To progress nutrition policy change and develop more effective advocates, it is useful to consider real-world factors and practical experiences of past advocacy efforts to determine the key barriers to and enablers of nutrition policy change. The present review aimed to identify and synthesize the enablers of and barriers to public policy change within the field of nutrition. DESIGN: Electronic databases were searched systematically for studies examining policy making in public health nutrition. An interpretive synthesis was undertaken. SETTING: International, national, state and local government jurisdictions within high-income, democratic countries. RESULTS: Sixty-three studies were selected for inclusion. Numerous themes were identified explaining the barriers to and enablers of policy change, all of which fell under the overarching category of 'political will', underpinned by a second major category, 'public will'. Sub-themes, including pressure from industry, neoliberal ideology, use of emotions and values, and being visible, were prevalent in describing links between public will, political will and policy change. CONCLUSIONS: The frustration around lack of public policy change in nutrition frequently stems from a belief that policy making is a rational process in which evidence is used to assess the relative costs and benefits of options. The findings from the present review confirm that evidence is only one component of influencing policy change. For policy change to occur there needs to be the political will, and often the public will, for the proposed policy problem and solution. The review presents a suite of enablers which can assist health professionals to influence political and public will in future advocacy efforts.

Using political science to progress public health nutrition: a systematic review.

OBJECTIVE: Poor dietary intake is the most important behavioural risk factor affecting health globally. Despite this, there has been little investment in public health nutrition policy actions. Policy process theories from the field of political science can aid understanding why policy decisions have occurred and identify how to influence ongoing or future initiatives. The present review aims to examine public health nutrition policy literature and identify whether a policy process theory has been used to analyse the process. DESIGN: Electronic databases were searched systematically for studies examining policy making in public health nutrition in high-income, democratic countries. SETTING: International, national, state and local government jurisdictions within high-income, democratic countries. SUBJECTS: Individuals and organisations involved in the nutrition policy-making process. RESULTS: Sixty-three studies met the eligibility criteria, most were conducted in the USA and a majority focused on obesity. The analysis demonstrates an accelerating trend in the number of nutrition policy papers published annually and an increase in the diversity of nutrition topics examined. The use of policy process theory was observed from 2003; however, it was utilised by only 14 % of the reviewed papers. CONCLUSIONS: There is limited research into the nutrition policy process in high-income countries. While there has been a small increase in the use of policy process theory from 2003, an opportunity to expand its use is evident. We suggest that nutrition policy making would benefit from a pragmatic approach that ensures those trying to influence or understand the policy-making process are equipped with basic knowledge around these theories.

Household food insecurity, diet, and weight status in a disadvantaged district of Ho Chi Minh City, Vietnam: a cross-sectional study.

BACKGROUND: Food security exists when all people, at all times, have physical, economic and socially acceptable access to safe, sufficient, and adequately nutritious food in order to meet their dietary needs for an active and healthy life. For high income countries and those experiencing the nutrition transition, food security is not only about the quantity of available food but also the nutritional quality as related to over- and under-nutrition. Vietnam is currently undergoing this nutrition transition, and as a result the relationship between food insecurity, socio-demographic factors and weight status is complex. The primary objective of this study was to therefore measure the prevalence of household food insecurity in a disadvantaged urban district in Ho Chi Minh City (HCMC) in Vietnam using a more comprehensive tool. This study also aims to examine the relationships between food insecurity and socio-demographic factors, weight status, and food intakes. METHODS: A cross-sectional study was conducted using multi-stage sampling. Adults who were mainly responsible for cooking were interviewed in 250 households. Data was collected on socioeconomic and demographic factors using previously validated tools. Food security was assessed using the Latin American and Caribbean Household Food Security Scale (ELCSA) tool and households were categorized as food secure or mildly, moderately or severely food insecure. Questions regarding food intake were based on routinely used and validated questions in HCMC, weight status was self-reported. RESULTS: Cronbach's alpha coefficient was 0.87, showing the ELCSA had a good internal reliability. Approximately 34.4% of households were food insecure. Food insecurity was inversely related to total household income (OR = 0.09, 95% CI = 0.04 - 0.22) and fruit intakes (OR = 2.2, 95% CI 1.31 - 4.22). There was no association between weight and food security status. CONCLUSIONS: Despite rapid industrialization and modernization, food insecurity remains an important public health issue in large urban areas of HCMC, suggesting that strategies to address food insecurity should be implemented in urban settings, and not just rural locations. Fruit consumption among food insecure households may be compromised because of financial difficulties, which may lead to poorer health outcomes particularly related to non-communicable disease prevention and management.

Breastfeeding beliefs and practices of African women living in Brisbane and Perth, Australia.

The purpose of this study was to explore the experience of breastfeeding among refugee women from Liberia, Sierra Leone, Burundi and the Democratic Republic of Congo living in two major capital cities in Australia. Participants were recruited from their relevant community associations and via a snowballing technique. Thirty-one women took part in either individual interviews or facilitated group discussions to explore their experiences of breastfeeding in their home country and in Australia. Thematic analysis revealed four main themes: cultural breastfeeding beliefs and practices; stigma and shame around breastfeeding in public; ambivalence towards breastfeeding and breastfeeding support. Women who originated from these four African countries highlighted a significant desire for breastfeeding and an understanding that it was the best method for feeding their infants. Their breastfeeding practices in Australia were a combination of practices maintained from their countries of origin and those adopted according to Australian cultural norms. They exemplified the complexity of breastfeeding behaviour and the relationship between infant feeding with economic status and the perceived social norms of the host country. The results illustrate the need for policy makers and health professionals to take into consideration the environmental, social and cultural contexts of the women who are purportedly targeted for the promotion of breastfeeding.

Can a text message a week improve breastfeeding?

BACKGROUND: Breastfeeding is recognised as the optimal method for feeding infants with health gains made by reducing infectious diseases in infancy; and chronic diseases, including obesity, in childhood, adolescence and adulthood. Despite this, exclusivity and duration in developed countries remains resistant to improvement. The objectives of this research were to test if an automated mobile phone text messaging intervention, delivering one text message a week, could increase "any" breastfeeding rates and improve breastfeeding self-efficacy and coping. METHODS: Women were eligible to participate if they were: over eighteen years; had an infant less than three months old; were currently breastfeeding; no diagnosed mental illness; and used a mobile phone. Women in the intervention group received MumBubConnect, a text messaging service with automated responses delivered once a week for 8 weeks. Women in the comparison group received their usual care and were sampled two years after the intervention group. Data collection included online surveys at two time points, week zero and week nine, to measure breastfeeding exclusivity and duration, coping, emotions, accountability and self-efficacy. A range of statistical analyses were used to test for differences between groups. Hierarchical regression was used to investigate change in breastfeeding outcome, between groups, adjusting for co-variates. RESULTS: The intervention group had 120 participants at commencement and 114 at completion, the comparison group had 114 participants at commencement and 86 at completion. MumBubConnect had a positive impact on the primary outcome of breastfeeding behaviors with women receiving the intervention more likely to continue exclusive breastfeeding; with a 6% decrease in exclusive breastfeeding in the intervention group, compared to a 14% decrease in the comparison group (p < 0.001). This remained significant after controlling for infant age, mother's income, education and delivery type (p = 0.04). Women in the intervention group demonstrated active coping and were less likely to display emotions-focussed coping (p < .001). There was no discernible statistical effect on self-efficacy or accountability. CONCLUSIONS: A fully automated text messaging services appears to improve exclusive breastfeeding duration. The service provides a well-accepted, personalised support service that empowers women to actively resolve breastfeeding issues.

Comparing the availability, price, variety and quality of fruits and vegetables across retail outlets and by area-level socio-economic position.

OBJECTIVE: To explore whether area-level socio-economic position or the form of retail stream (conventional v. farmers' market) is associated with differences in the price, availability, variety and quality of a range of fresh fruit and vegetables. DESIGN: A multi-site cross-sectional pilot study of farmers' markets, supermarkets and independent fruit and vegetable retailers. Each was surveyed to assess the price, availability, variety and quality of fifteen fruit and eighteen vegetable items. SETTING: Retail outlets were located in south-east Queensland. SUBJECTS: Fifteen retail outlets were surveyed (five of each retail stream). RESULTS: Average basket prices were not significantly different across the socio-economic spectrum, but prices in low socio-economic areas were cheapest. Availability, variety and quality did not differ significantly across levels of socio-economic position; however, the areas with the most socio-economic disadvantage scored poorest for quality and variety. Supermarkets had significantly better fruit and vegetable availability than farmers' markets, although price, variety and quality scores were not different across retail streams. Results demonstrate a trend to fruit and vegetable prices being more expensive at farmers' markets, with the price of the fruit basket being significantly greater at the organic farmers' market compared with the non-organic farmers' markets. CONCLUSIONS: Neither area-level socio-economic position nor the form of retail stream was significantly associated with differences in the availability, price, variety and quality of fruit and vegetables, except for availability which was higher in supermarkets than farmers' markets. Further research is needed to determine what role farmers' markets can play in affecting fruit and vegetable intake.

Food insecurity among adults residing in disadvantaged urban areas: potential health and dietary consequences.

OBJECTIVE: Food insecurity is the limited or uncertain availability or access to nutritionally adequate, culturally appropriate and safe foods. Food insecurity may result in inadequate dietary intakes, overweight or obesity and the development of chronic disease. Internationally, few studies have focused on the range of potential health outcomes related to food insecurity among adults residing in disadvantaged locations and no such Australian studies exist. The objective of the present study was to investigate associations between food insecurity, sociodemographic and health factors and dietary intakes among adults residing in disadvantaged urban areas. DESIGN: Data were collected by mail survey (n 505, 53 % response rate), which ascertained information about food security status, demographic characteristics (such as age, gender, household income, education) fruit and vegetable intakes, takeaway and meat consumption, general health, depression and chronic disease. SETTING: Disadvantaged suburbs of Brisbane city, Australia, 2009. SUBJECTS: Individuals aged ≥ 20 years. RESULTS: Approximately one in four households (25 %) was food insecure. Food insecurity was associated with lower household income, poorer general health, increased health-care utilisation and depression. These associations remained after adjustment for age, gender and household income. CONCLUSIONS: Food insecurity is prevalent in urbanised disadvantaged areas in developed countries such as Australia. Low-income households are at high risk of experiencing food insecurity. Food insecurity may result in significant health burdens among the population, and this may be concentrated in socio-economically disadvantaged suburbs.

Food insecurity among Australian children: potential determinants, health and developmental consequences.

Children in food-insecure households may be at risk of poor health, developmental or behavioural problems. This study investigated the associations between food insecurity, potential determinants and health and developmental outcomes among children. Data on household food security, socio-demographic characteristics and children's weight, health and behaviour were collected from households with children aged 3-17 years in socioeconomically disadvantaged suburbs by mail survey using proxy-parental reports (185 households). Data were analysed using logistic regression. Approximately one-in-three households (34%) were food insecure. Low household income was associated with an increased risk of food insecurity [odds ratio (OR), 16.20; 95% confidence interval (CI), 3.52-74.47]. Children with a parent born outside of Australia were less likely to experience food insecurity (OR, 0.42; 95% CI, 0.19-0.93). Children in food-insecure households were more likely to miss days from school or activities (OR, 3.52; 95% CI, 1.46-8.54) and were more likely to have borderline or atypical emotional symptoms (OR, 2.44; 95% CI, 1.11-5.38) or behavioural difficulties (OR, 2.35; 95% CI, 1.04-5.33). Food insecurity may be prevalent among socioeconomically disadvantaged households with children. The potential developmental consequences of food insecurity during childhood may result in serious adverse health and social implications.
