Food availability, cost disparity and improvement in relation to accessibility and remoteness in Queensland

Food insecurity among consumers from rural areas in Romania

Food security has a special relevance in nowadays economies, due to the current crisis, characterized by multiple layers on a social, political, economic, and individual biological level. The present study aims to identify relevant aspects of food insecurity for consumers in rural Romania and the main factors that significantly influence it (food availability, food access, and food consumption). The data were collected from a sample of 875 consumers from rural areas in Romania. The results show that food insecurity is perceived by the consumers of Romanian rural households as being strongly influenced by food availability, but less influenced by food consumption and access. The results have an essential relevance in the development of agri-food marketing strategies and public policies in the field of sustainable development.

Conceptualisation, experiences and suggestions for improvement of food security amongst Aboriginal and Torres Strait Islander parents and carers in remote Australian communities

This study aimed to determine perceptions of the lived experience of food insecurity and suggestions to improve food security in four remote Aboriginal communities in the Northern Territory, and Queensland. Participants were Aboriginal and/or Torres Strait Islander pregnant and breastfeeding women, and parents/carers of children aged six months to five years. Semi-structured interviews (n=17) were conducted between June-July 2021 and the data thematically analysed using a four stage process. No specific term was used by participants to describe being either food secure or insecure. Descriptions of food security were centred in food sharing, food sufficiency, and family activities. Elements describing food insecurity were physical pain and emotional stress, adults going without food, seeking family help and managing without food until payday. Factors contributing to food insecurity were reported to be: (i) Low income and unemployment, (ii) Cost of living remotely, (iii) Resource sharing, and (iv) Impact of spending on harmful commodities and activities. Three themes were conceptualised: (1) Cultural practices buffer food insecurity, (2) Coping with food insecurity, (3) People accept a degree of food insecurity as normal. Findings suggest Aboriginal and Torres Strait Islander cultural practices such as sharing food buffer episodic food insecurity and constitute 'cultural food security'. Despite use of cultural practices (e.g., procuring traditional food) and generic coping strategies, regular episodes of food insecurity often aligned with the off week of social assistance payments. Household energy (electricity) security was coupled to food security. Suggestions for improving food security included better transport and food access, extending electricity rebates, increases in the regularity of social assistance payments, and computer access and training in budgeting. Policies to advance food security should embody deeper Aboriginal and Torres Strait Islander descriptions and experiences. Community-derived policy suggestions which aim to increase access to adequate, regular, stable household income are likely to succeed.

The Retail Food Sector and Indigenous Peoples in High-Income Countries: A Systematic Scoping Review

Indigenous Peoples in high-income countries experience higher burdens of food insecurity, obesity, and diet-related health conditions compared to national averages. The objective of this systematic scoping review is to synthesize information from the published literature on the methods/approaches, findings, and scope for research and interventions on the retail food sector servicing Indigenous Peoples in high-income countries. A structured literature search in two major international databases yielded 139 relevant peer-reviewed articles from nine countries. Most research was conducted in Oceania and North America, and in rural and remote regions. Several convergent issues were identified across global regions including limited grocery store availability/access, heightened exposure to unhealthy food environments, inadequate market food supplies (i.e., high prices, limited availability, and poor quality), and common underlying structural factors including socio-economic inequality and colonialism. A list of actions that can modify the nature and structure of retailing systems to enhance the availability, accessibility, and quality of healthful foods is identified. While continuing to (re)align research with community priorities, international collaboration may foster enhanced opportunities to strengthen the evidence base for policy and practice and contribute to the amelioration of diet quality and health at the population level.

Vitamin A-Related Policies in Iran: Document Analysis

Background:

There are one-third of children in the world with Vitamin A deficiency. The prevalence of vitamin deficiency in children aged 15–23 months in Iran has increased 18 times and in rural areas. The present article aims to an analysis of related documents to the existing policies on this vitamin in our country.

Materials and Methods:

This study is a descriptive study using a quantitative content analysis approach to analyze nutritional policy documents.

Results:

We extracted six themes at the first stage of analysis (based on common policies in the world), which were reduced to two final themes: “Direct interventions” and “Indirect interventions.” There were also six subthemes and eight issues.

Conclusions:

It seems that policymaking must revise these documents and also making new policy decision with more emphasis on micronutrient.

A systematic review of the Australian food retail environment: Characteristics, variation by geographic area, socioeconomic position and associations with diet and obesity

There is strong support across multiple sectors for the implementation of policies to create healthier food environments as part of comprehensive strategies to address obesity and improve population diets. The existing evidence base describing food retail environments and their relationship with health outcomes is limited in several respects. This systematic review examines the current evidence regarding food retail environments in Australia, including associations with diet and people with obesity, and socioeconomic and geographic disparities. Three databases were searched and independently screened. Studies were included if they were undertaken in Australia and objectively measured the food retail environment. Sixty papers were included. The broad range of methodological approaches used across studies limited the ability to synthesize the evidence and draw conclusions. Results indicated that there is some evidence that disparities exist in food retail environments across measures of socioeconomic position and geographic area in parts of Australia. Overall, there were inconsistent findings regarding the association between the healthiness of food retail environments and diet or people with obesity. Findings support previous calls for standardized tools and measures for monitoring the healthiness of food retail environments. This is imperative to inform evidence-based policy and evaluation in this critical component of recommended obesity prevention strategies.

Low proportions of folic acid deficiency after introduction of mandatory folic acid fortification in remote areas of northern Queensland, Australia: a secondary health data analysis

Background: Australia implemented mandatory folic acid fortification of bread-making flour in 2009. Objective: To assess the impact of folic acid fortification in remote vs. regional urban areas and Indigenous vs. non-Indigenous populations in northern Queensland. Methods: Routinely collected data on folic acid measurements in remote areas and two regional urban centres in northern Queensland between 2004 and 2015 were analysed (n = 13,929) dichotomously (folic deficient vs. non-deficient). Results: Overall prevalence of folic acid deficiency was 3.2% (235/7282) in urban centres compared with 7.2% (480/6647) in remote areas (p < 0.001), and 9.3% (393/4240) in the Indigenous population compared with 3.2% (273/8451) in the non-Indigenous population (p < 0.001). Prevalence of folic acid deficiency dropped from 12.2% (n = 481) in 2004-2008 to 1.5% (n = 126) in 2010-2015 (p < 0.001). This translates into a relative risk reduction (RRR) of 88%. RRR was 79% (7.2% vs. 1.5%) in urban centres, 91% (17.3% vs. 1.5%) in remote areas, 92% (20.5% vs. 1.6%) in the Indigenous population and 80% (7.4% vs. 1.5%) in the non-Indigenous population (p < 0.001 for all). Conclusions: Substantial declines of folic acid deficiency to low and comparable proportions in former high-risk populations indicate that mandatory folic acid fortification of flour has had a population-wide benefit in northern Queensland.

Is the type and location of grocery stores a predictor of healthy and unhealthy food availability? A cross-sectional study

AIM

To investigate whether geographical location or type of store is associated with differences in healthy and unhealthy food availability in grocery stores.

METHODS

A cross-sectional study using the Victorian Healthy Food Basket to measure food availability (44 'healthy' and 10 'unhealthy' items) in a convenience sample of 112 stores in urban and regional Victoria, Australia. Logistic regression analyses assessed whether location (regional, urban), distance from capital city central business district (km) and type of store (chain supermarket, independent supermarket and general store) predicted the number of missing healthy and unhealthy food items.

RESULTS

There were 54 chain supermarkets, 43 independent supermarkets and 15 general stores, with 56% of stores located in urban areas and 44% located regionally. The strongest significant predictor of missing items was being a general store, which had greater odds (odds ratio (OR) = 136, 95% confidence interval (CI) = 13-1399) of having missing 'healthy' items and missing 'unhealthy' items (OR = 63, 95% CI = 7-575), compared with chain supermarkets. Independent supermarkets had increased odds of having missing 'healthy' items (OR = 7, 95% CI = 2-22) compared with chain supermarkets. Regional store location was a significant predictor of missing 'healthy' and 'unhealthy' items, compared with urban location (OR = 6, 95% CI = 2-25) and (OR = 7, 95% CI = 2-29), respectively.

CONCLUSIONS

Store type was a stronger predictor of stores having missing 'healthy' and 'unhealthy' food items than the store distance from a large urban centre. General stores and independent supermarkets may be important settings for interventions to improve availability of healthy food.

What is known about consumer nutrition environments in Australia? A scoping review of the literature

OBJECTIVE

Food environments can influence food selection and hold the potential to reduce obesity, non-communicable diseases and their inequalities. 'Consumer nutrition environments' describe what consumers encounter within a food retail outlet, including products, price, promotion and placement. This study aimed to summarize the attributes that have been examined in existing peer-reviewed studies of Australian consumer nutrition environments, identify knowledge gaps and provide recommendations for future research.

METHODS

A systematic search of peer-reviewed literature was conducted. Sixty-six studies that assessed an aspect of within-store consumer nutrition environments were included.

RESULTS

Most studies were published from 2011 onwards and were conducted in capital cities and in supermarkets. Studies assessed the domains of product (40/66), price (26/66), promotion (16/66) and placement (6/66). The most common research themes identified were assessment of the impact of area socioeconomic status (13/66), remoteness (9/66) and food outlet type (7/66) on healthy food prices; change in price of healthy foods (6/66); variety of healthy foods (5/66); and prevalence of unhealthy child-orientated products (5/66).

CONCLUSIONS

This scoping review identified a large number of knowledge gaps. Recommended priorities for researchers are as follows: (1) develop consistent observational methodology, (2) consider consumer nutrition environments in rural and remote communities, (3) develop an understanding of food service outlets, (4) build on existing evidence in all four domains of product, price, placement and promotion and (5) determine effective policy and store-based interventions to increase healthy food selection.

Removing the Australian tax exemption on healthy food adds food stress to families vulnerable to poor nutrition

OBJECTIVE

To assess the impact of changing the Australian Goods and Services Tax (GST) on household food stress, which occurs when >25% of disposable income needs to be spent on food.

METHODS

Weekly healthy meal plan costs for average-income (AI), low-income (LI) and welfare-dependent (WDI) families were calculated using the 2013 Western Australian (WA) Food Access and Costs Survey. Four GST scenarios were compared: 1) status quo; 2) increasing GST to 15%; 3) expanding base to include exempt foods at 10% GST; and 4) expanding base to include exempt foods and increasing the tax to 15%.

RESULTS

Single-parent families risk food stress regardless of their income or the GST scenario (requiring 24-42% of disposable income). The probability of food stress in Scenario 1 is 100% for WDI two-parent families and 36% for LI earners. In Scenarios 3 and 4, food stress probability is 60-72% for two-parent LI families and AI single-parent families, increasing to 88-94% if residing in very remote areas.

CONCLUSION

There is food stress risk among single-parent, LI and WDI families, particularly those residing in very remote areas. Implications for public health: Expanding GST places an additional burden on people who are already vulnerable to poor nutrition and chronic disease due to their socioeconomic circumstances.

Costing ‘healthy’ food baskets in Australia – a systematic review of food price and affordability monitoring tools, protocols and methods

Objective

To undertake a systematic review to determine similarities and differences in metrics and results between recently and/or currently used tools, protocols and methods for monitoring Australian healthy food prices and affordability.

Design

Electronic databases of peer-reviewed literature and online grey literature were systematically searched using the PRISMA approach for articles and reports relating to healthy food and diet price assessment tools, protocols, methods and results that utilised retail pricing.

Setting

National, state, regional and local areas of Australia from 1995 to 2015.

Subjects

Assessment tools, protocols and methods to measure the price of ‘healthy’ foods and diets.

Results

The search identified fifty-nine discrete surveys of ‘healthy’ food pricing incorporating six major food pricing tools (those used in multiple areas and time periods) and five minor food pricing tools (those used in a single survey area or time period). Analysis demonstrated methodological differences regarding: included foods; reference households; use of availability and/or quality measures; household income sources; store sampling methods; data collection protocols; analysis methods; and results.

Conclusions

‘Healthy’ food price assessment methods used in Australia lack comparability across all metrics and most do not fully align with a ‘healthy’ diet as recommended by the current Australian Dietary Guidelines. None have been applied nationally. Assessment of the price, price differential and affordability of healthy (recommended) and current (unhealthy) diets would provide more robust and meaningful data to inform health and fiscal policy in Australia. The INFORMAS ‘optimal’ approach provides a potential framework for development of these methods.

Monitoring the price and affordability of foods and diets globally

Food prices and food affordability are important determinants of food choices, obesity and non-communicable diseases. As governments around the world consider policies to promote the consumption of healthier foods, data on the relative price and affordability of foods, with a particular focus on the difference between 'less healthy' and 'healthy' foods and diets, are urgently needed. This paper briefly reviews past and current approaches to monitoring food prices, and identifies key issues affecting the development of practical tools and methods for food price data collection, analysis and reporting. A step-wise monitoring framework, including measurement indicators, is proposed. 'Minimal' data collection will assess the differential price of 'healthy' and 'less healthy' foods; 'expanded' monitoring will assess the differential price of 'healthy' and 'less healthy' diets; and the 'optimal' approach will also monitor food affordability, by taking into account household income. The monitoring of the price and affordability of 'healthy' and 'less healthy' foods and diets globally will provide robust data and benchmarks to inform economic and fiscal policy responses. Given the range of methodological, cultural and logistical challenges in this area, it is imperative that all aspects of the proposed monitoring framework are tested rigorously before implementation.

Food scarcity, not economic constraint limits consumption in a rural Aboriginal community

OBJECTIVE

To determine whether food scarcity or economic constraint is more strongly associated with purchasing patterns in a rural Aboriginal community.

DESIGN

Store receipts were collected to determine money spent in the community shop across a four-month period from January to April 2006. Variability in expenditures is then studied using measures of food scarcity (days since shop loading) and economic constraint (days since payday).

SETTING

Parnngurr Outstation in the Western Desert of Australia.

MAIN OUTCOME MEASURES

Daily gross and per-household gross expenditures at the community shop.

RESULTS

  There is a significant association between food scarcity and money spent in the shop (-42.89, confidence interval -62.62 to -23.18, P < 0.001). There is no association between economic constraint and money spent in the shop.

CONCLUSION

In rural and remote communities, reliable access to food is critical to food security. Circumstantial constraints such as seasonal flooding and political insecurity can augment food access problems and put Aboriginal people at risk of malnutrition and other dietary harms.

A comparison of the cost of generic and branded food products in Australian supermarkets

OBJECTIVE

Food cost is an important factor influencing the consumption of nutritious foods and subsequent chronic disease risk. The present study compared the cost of branded food products with their generic equivalents across a range of food categories.

SETTING

The survey was conducted within two major supermarket chains across six locations in Sydney, Australia (n 12).

DESIGN

Price differences were calculated for 'core' (nutrient dense and low in energy) and 'extra' (high in undesirable nutrients and/or energy) packaged foods (n 22) between generic and branded items.

RESULTS

A cost saving of 44 % was found by purchasing generic over branded products across all food categories. The most significant savings were for core foods, such as bread and cereals, and the smallest cost savings were seen for fruit products. There was little variation in cost saving between branded and generic products by socio-economic status of the supermarket location.

CONCLUSIONS

The large price differential between branded and generic food products implies that consumers, particularly those on lower incomes, could benefit financially from purchasing generic items. The promotion of core generic products may be an effective strategy to assist people on lower incomes to meet dietary guidelines.

Socio-economic status, racial composition and the affordability of fresh fruits and vegetables in neighborhoods of a large rural region in Texas

Background

Little is known about how affordability of healthy food varies with community characteristics in rural settings. We examined how the cost of fresh fruit and vegetables varies with the economic and demographic characteristics in six rural counties of Texas.

Methods

Ground-truthed data from the Brazos Valley Food Environment Project were used to identify all food stores in the rural region and the availability and lowest price of fresh whole fruit and vegetables in the food stores. Socioeconomic characteristics were extracted from the 2000 U.S. Census Summary Files 3 at the level of the census block group. We used an imputation strategy to calculate two types of price indices for both fresh fruit and fresh vegetables: a high variety and a basic index; and evaluated the relationship between neighborhood economic and demographic characteristics and affordability of fresh produce, using linear regression models.

Results

The mean cost of meeting the USDA recommendation of fruit consumption from a high variety basket of fruit types in our sample of stores was just over $27.50 per week. Relying on the three most common fruits lowered the weekly expense to under $17.25 per week, a reduction of 37.6%. The effect of moving from a high variety to a low variety basket was much less when considering vegetable consumption: a 4.3% decline from $29.23 to $27.97 per week. Univariate regression analysis revealed that the cost of fresh produce is not associated with the racial/ethnic composition of the local community. However, multivariate regression showed that holding median income constant, stores in neighborhoods with higher percentages of Black residents paid more for fresh fruits and vegetables. The proportion of Hispanic residents was not associated with cost in either the univariate or multivariate analysis.

Conclusion

This study extends prior work by examining the affordability of fresh fruit and vegetables from food stores in a large rural area; and how access to an affordable supply of fresh fruit and vegetables differs by neighborhood inequalities. The approach and findings of this study are relevant and have important research and policy implications for understanding access and availability of affordable, healthy foods.

Neighborhood deprivation, vehicle ownership, and potential spatial access to a variety of fruits and vegetables in a large rural area in Texas

OBJECTIVE

There has been limited study of all types of food stores, such as traditional (supercenters, supermarkets, and grocery stores), convenience stores, and non-traditional (dollar stores, mass merchandisers, and pharmacies) as potential opportunities for purchase of fresh and processed (canned and frozen) fruits and vegetables, especially in small-town or rural areas.

METHODS

Data from the Brazos Valley Food Environment Project (BVFEP) are combined with 2000 U.S. Census data for 101 Census block groups (CBG) to examine neighborhood access to fruits and vegetables. BVFEP data included identification and geocoding of all food stores (n = 185) in six rural counties in Texas, using ground-truthed methods and on-site assessment of the availability and variety of fresh and processed fruits and vegetables in all food stores. Access from the population-weighted centroid of each CBG was measured using proximity (minimum network distance) and coverage (number of shopping opportunities) for a good selection of fresh and processed fruits and vegetables. Neighborhood inequalities (deprivation and vehicle ownership) and spatial access for fruits and vegetables were examined using Wilcoxon matched-pairs signed-rank test and multivariate regression models.

RESULTS

The variety of fruits or vegetables was greater at supermarkets compared with grocery stores. Among non-traditional and convenience food stores, the largest variety was found at dollar stores. On average, rural neighborhoods were 9.9 miles to the nearest supermarket, 6.7 miles and 7.4 miles to the nearest food store with a good variety of fresh fruits and vegetables, respectively, and 4.7 miles and 4.5 miles to a good variety of fresh and processed fruits or vegetables. High deprivation or low vehicle ownership neighborhoods had better spatial access to a good variety of fruits and vegetables, both in the distance to the nearest source and in the number of shopping opportunities.

CONCLUSION

Supermarkets and grocery stores are no longer the only shopping opportunities for fruits or vegetables. The inclusion of data on availability of fresh or processed fruits or vegetables in the measurements provides robust meaning to the concept of potential access in this large rural area.

A healthy diet consistent with Australian health recommendations is too expensive for welfare-dependent families

OBJECTIVE

Examine the cost of healthy food habits for welfare-dependent families in Australia.

METHOD

A seven-day meal plan was developed, based on Australian public health recommendations, for two typical welfare-dependent families: a couple-family (two adults, two children) and a one-parent family (one adult, two children). The cost of the meal plan was calculated using market brand and generic brand grocery items, and total cost compared to income.

RESULTS

In Australia, the cost of healthy food habits uses about 40% of the disposable income of welfare-dependent families. Families earning an average income would spend only 20% of their disposable income to buy the same healthy food. Substituting generic brands for market brands reduced the weekly food cost by about 13%. This is one of few economic models to include generic brands.

CONCLUSION

Compared with average-income Australian families, healthy food habits are a fiscal challenge to welfare-dependent families.

IMPLICATIONS

These results provide a benchmark for economic and social policy analysis, and the influence disposable income has on prioritising healthy food habits.

Correlates of availability and accessibility of fruits and vegetables in homes of low-income Hispanic families

Availability and accessibility (AA) has been consistently shown across studies as the most important correlate of fruits and vegetables (FV) intake. However, there is little data on factors that influence AA of FV, especially in Hispanic families. The objective of this cross-sectional study was to examine the association between parental factors, child's preferences for FV and AA of FV in homes of low-income Hispanic families with children 5-12 years old. A convenience sample of 184 parents of low socioeconomic status recruited through public elementary schools completed a self-administered questionnaire about demographics, language spoken at home and food insecurity (FI). Parental factors and child's preferences were measured using a 16-item questionnaire, which was developed specifically for the study. AA of FV was measured using a validated nine-item index. Hierarchical multiple regression analysis indicated that language spoken at home, parental practices that promote consumption of FV, parental role modeling and perceived benefits of fast food had significant and independent associations with AA of FV at home. Intervention programs should take into consideration the language spoken at home and target at improving parental factors in order to improve AA of FV.

Ethnic differences in body composition and anthropometric characteristics in Australian Caucasian and urban Indigenous children

The objective was to compare ethnic differences in anthropometry, including size, proportions and fat distribution, and body composition in a cohort of seventy Caucasian (forty-four boys, twenty-six girls) and seventy-four urban Indigenous (thirty-six boys, thirty-eight girls) children (aged 9–15 years). Anthropometric measures (stature, body mass, eight skinfolds, thirteen girths, six bone lengths and five bone breadths) and body composition assessment using dual-energy X-ray absorptiometry were conducted. Body composition variables including total body fat percentage and percentage abdominal fat were determined and together with anthropometric indices, including BMI (kg/m2), abdominal:height ratio (AHtR) and sum of skinfolds, ethnic differences were compared for each sex. After adjustment for age, Indigenous girls showed significantly (P < 0·05) greater trunk circumferences and proportion of overweight and obesity than their Caucasian counterparts. In addition, Indigenous children had a significantly greater proportion (P < 0·05) of trunk fat. The best model for total and android fat prediction included sum of skinfolds and age in both sexes (>93 % of variation). Ethnicity was only important in girls where abdominal circumference and AHtR were included and Indigenous girls showed significantly (P < 0·05) smaller total/android fat deposition than Caucasian girls at the given abdominal circumference or AHtR values. Differences in anthropometric and fat distribution patterns in Caucasian and Indigenous children may justify the need for more appropriate screening criteria for obesity in Australian children relevant to ethnic origin.

Measures of the food environment: a compilation of the literature, 1990-2007

BACKGROUND

Valid and reliable measures are required to assess any effect of the food environment on individual dietary behavior, and form the foundation of research that may inform obesity-related policy. Although many methods of measuring the food environment exist, this area of research is still relatively new and there has been no systematic attempt to gather these measures, to compare and contrast them, or to report on their psychometric properties.

EVIDENCE ACQUISITION

A structured literature search was conducted to identify peer-reviewed articles published between January 1990 and August 2007 that measured the community-level food environment. These articles were categorized into the following environments: food stores, restaurants, schools, and worksites. The measurement strategies in these studies were categorized as instruments (checklists, market baskets, inventories, or interviews/questionnaires) or methodologies (geographic, sales, menu, or nutrient analyses).

EVIDENCE SYNTHESIS

A total of 137 articles were identified that included measures of the food environment. Researchers focused on assessing the accessibility, availability, affordability, and quality of the food environment. The most frequently used measure overall was some form of geographic analysis. Eighteen of the 137 articles (13.1%) tested for any psychometric properties, including inter-rater reliability, test-retest reliability, and/or validity.

CONCLUSIONS

A greater focus on testing for reliability and validity of measures of the food environment may increase rigor in research in this area. Robust measures of the food environment may strengthen research on the effects of the community-level food environment on individual dietary behavior, assist in the development and evaluation of interventions, and inform policymaking targeted at reducing the prevalence of obesity and improving diet.

Environmental and societal influences acting on cardiovascular risk factors and disease at a population level: a review

It has long been known that cardiovascular disease (CVD) rates vary considerably among populations, across space and through time. It is now apparent that most of the attributable risk for myocardial infarction 'within' populations from across the world can be ascribed to the varying levels of a limited number of risk factors among individuals in a population. Individual risk factors (e.g. blood pressure) can be modified with resulting health gains. Yet, the persistence of large international variations in cardiovascular risk factors and resulting CVD incidence and mortality indicates that there are additional factors that apply to 'populations' that are important to understand as part of a comprehensive approach to CVD control. This article reviews the evidence on why certain populations are more at risk than others.

Selecting interventions to promote fruit and vegetable consumption: from policy to action, a planning framework case study in Western Australia

Background

The Department of Health in Western Australia identified access to, and daily consumption of recommended amounts of fruit and vegetables, as priority health determinants. The numerous factors that influence supply and consumption of fruit and vegetables indicated that a comprehensive approach would be required.

A government and non-government sector steering group was set up to select priority interventions using the National Public Health Partnership's Framework for Implementing Public Health Strategies. This structured framework was used for developing strategies to improve fruit and vegetable consumption and supply, and to identify implementation priorities.

After one year a desktop audit of progress on framework interventions was undertaken.

Results

The structured framework led to a plan for defined actions, partners, costs, and performance indicators for strategies to improve fruit and vegetable consumption and supply. Lead agency custodians for management of the selected interventions were identified.

After one year there was significant progress in the implementation of a number of the high-ranking interventions. The exception was interventions that provide the infrastructure support such as research and development capacity, information systems.

Conclusion

A structured framework and stakeholder participation assisted in developing a fruit and vegetable implementation strategy. Engagement and commitment of influential and diverse stakeholders is needed, not just for program support, but particularly in the areas of food and nutrition policy development and providing the infrastructure support required. Further work is required to develop performance outcomes and cost effectiveness measures for many of the strategies that have been proposed to address portfolio objectives.

Exploring potential dietary contributions including traditional seafood and other determinants of urinary cadmium levels among indigenous women of a Torres Strait Island (Australia)

Indigenous people of the Torres Strait Islands have been concerned about the safety of their traditional seafoods since the discovery of high cadmium levels in the liver and kidney of dugong and turtle in 1996. This study explored links between urinary cadmium levels and consumption frequency of these traditional foods and piloted a community-based methodology to identify potential determinants of cadmium exposure and accumulation. Consultations led to selection of one community for study from which 60 women aged 30 to 50 years participated in health and food frequency survey, urine collection and a routine health check. Urinary cadmium levels were determined by inductively coupled plasma-mass spectrometry; data were analysed using SPSS-14. The geometric mean cadmium level in this group of women was 1.17 (arithmetic mean 1.86) microg/g creatinine with one-third exceeding 2.0 microg/g creatinine. Heavy smoking (>or=300 pack years) was linked to higher cadmium in urine, as was increasing age and waist circumference. Analysis of age-adjusted residuals revealed significant associations (P<0.05) between cadmium level and higher consumption of turtle liver and kidney, locally gathered clams, peanuts, coconut, chocolate and potato chips. Dugong kidney consumption approached significance (P=0.06). Multiple regression revealed that 40% (adjusted r(2)) of variation in cadmium level was explained by the sum of these associated foods plus heavy smoking, age and waist circumference. No relationships between cadmium and pregnancy history were found. This paper presents a novel approach to explore contributions of foods and other factors to exposure to toxins at community level and the first direct evidence that frequent turtle (and possibly dugong) liver and kidney and wild clam consumption is linked to higher urinary cadmium levels among Torres Strait Islander women.

Food supply adequacy in the Lower Mississippi Delta

OBJECTIVE

To assess food supply adequacy within 3 food store types in the Lower Mississippi Delta.

DESIGN

Regional food store survey to determine availability and quality of 102 food items in 62 supermarkets, 77 small/medium stores, and 86 convenience stores.

SETTING

Lower Mississippi Delta region of the United States.

PARTICIPANTS

225 food stores in 18 counties.

MAIN OUTCOME MEASURES

Percentage of Thrifty Food Plan (TFP) food items available and quality ratings of 6 food sections across store types.

RESULTS

On average, supermarkets carried 96% of the items that compose the TFP. Mean percentage of TFP carried in small/medium stores was 50%. Convenience stores carried 28% of the TFP items. Supermarkets had higher overall quality ratings and quality ratings for fresh and frozen foods compared to small/medium and convenience stores (P<.01).

IMPLICATIONS FOR RESEARCH AND PRACTICE

Although supermarkets carried a large percentage of items surveyed, the number of supermarkets in this region is limited. Community residents with limited transportation to reach supermarkets may experience limited food supply adequacy. Therefore, community-based nutrition interventions should include partnerships with small/medium food retailers while trying to impact residents' food choices within those stores.

Does living in a disadvantaged area entail limited opportunities to purchase fresh fruit and vegetables in terms of price, availability, and variety? Findings from the Brisbane Food Study

Understanding the role environmental factors may play in the dietary behaviours of socioeconomic groups is relevant for efforts to reduce health inequalities. In contrast with international research, earlier findings from the Brisbane Food Study (BFS), Australia, found no relationship between area socioeconomic characteristics and dietary behaviours or location of food shops. This paper examines whether the price and availability of fruits and vegetables are socioeconomically patterned using data from the BFS. Fifty census collection districts were randomly sampled and all local (i.e. within 2.5 km) supermarkets, greengrocers and convenience stores were observed. Little or no differences in price and availability were found on the basis of area socioeconomic characteristics.

Does living in a disadvantaged area mean fewer opportunities to purchase fresh fruit and vegetables in the area? Findings from the Brisbane food study

Understanding the particularly low intake of fruits and vegetables among socioeconomically disadvantaged groups is an important issue for public health. This study investigated whether access to retail outlets is similar across areas of varying socioeconomic disadvantage in an Australian urban setting, in terms of distance, the numbers of local shops, and their opening hours. This ecological cross-sectional study used 50 randomly sampled census collection districts and their nearby shopping environment (i.e. within 2.5 km), and generally found minimal or no socioeconomic differences in shopping infrastructure. Important methodological and social/economic issues may explain this contrast with overseas findings.
