Food counts. Measuring food consumption and expenditures in household consumption and expenditure surveys (HCES). Introduction to the special issue

This introductory paper presents the results of an international multi-disciplinary research project on the measurement of food consumption in national household surveys. Food consumption data from household surveys are possibly the single most important source of information on poverty, food security, and nutrition outcomes at national, sub-national and household level, and contribute building blocks to global efforts to monitor progress towards the major international development goals.The paper synthesizes case studies from a diverse set of developing and OECD countries, looking at some of the main outstanding research issues as identified by a recent international assessment of 100 existing national household surveys (Smith et al., 2014). The project mobilized expertise from different disciplines (statistics, economics, food security, nutrition) to work towards enhancing our understanding of how to improve the quality and availability of food consumption and expenditure data, while making them more valuable for a diverse set of users. The individual studies summarized in this paper analyze, both theoretically and empirically, how different surveys design options affect the quality of the data being collected and, in turn, the implications for statistical inference and policy analysis.The conclusions and recommendations derived from this collection of studies will be instrumental in advancing the methodological agenda for the collection of household level food data, and will provide national statistical offices and survey practitioners worldwide with practical insights for survey design, while providing poverty, food and nutrition policymakers with greater understanding of these issues, as well as improved tools for and better guidance in policy formulation.     

Expenditure Pattern for Food Away from Home Consumption in Turkey

ABSTRACT

One of the largest recent changes in consumer food purchasing behavior is the trend towards greater consumption of food eaten outside the home. Between 1994 and 2000, the share of total food expenditures spent on food away from home (FAFH) increased from 7 to 15% with an increasing share for fast-food facilities. This study focuses on whether demographic and socioeconomic factors have detectable effects on Turkish FAFH expenditures. This question is of interest because previous studies suggest that increasing household income, education, female labor participation and changing lifestyle especially in developing countries increased household FAFH consumption share but decreased food at home consumption share. However, no study to our knowledge has examined the combined effect of income, education, employment, and family status on Turkish FAFH consumption. The data for this research were obtained from personal interviews of representative sample households of the province of Adana in Turkey. The findings of this study generally indicate that restaurant facilities, employment of wife and education, composition of household, and income are statistically significant determinants of FAFH consumption.     

Does mandatory food safety training and certification for restaurant employees improve inspection outcomes?

The purpose of this study was to explore the relationship between mandatory food safety training and certification and inspection results of chain restaurants and independent restaurants, using current food safety inspection results of food service establishments in Central Florida. More specifically, this study examines whether there is any statistically significant difference in the violation frequency among chain and independent restaurants. Reducing the risk of any foodborne illness is a critical strategy that industry stakeholders should pursue in an area dominated by tourism such as Orlando, Florida. A one-way ANOVA was used to determine the differences between the two types of restaurants. Findings indicate that there is significant difference between chain and independent restaurants for critical violations. No difference was found when comparing chain verses independent restaurants for non-critical violations.     

Understanding the retirement-consumption puzzle through the lens of food consumption-fuzzy regression-discontinuity evidence from urban China

This paper provides an understanding of the widely-documented retirement-consumption puzzle from the perspective of food consumption. Exploiting the mandatory retirement age cut-off for public-sector male employees in urban China to obtain a source of exogenous variation in their retirement status, this paper identifies the causal impacts of retirement on four major aspects of their food consumption: food expenditure, time spent in food acquisition, the quantity and quality of food consumed. Based on data from the China Health and Nutrition Survey, our fuzzy regression-discontinuity analysis finds that, consistent with the retirement-consumption puzzle, retirement reduces elderly males’ total food expenditure by 49–55%. However, retirement barely changes the quantity of food they consume (measured by total calorie intakes). Further analysis suggests that elderly males substitute time for money in food acquisition upon retirement, which helps to reconcile the differential impacts of retirement on food expenditure and food consumption. Finally, retirement greatly changes elderly males’ diet structure. They consume significantly less food with animal origins (and thus less fat and protein) and more grains (and thus more carbohydrate) upon retirement, which undermines their diet balance by the standards provided by the Chinese Nutrition Association.     

Status of development,regulation and adoption of GM agriculture in Africa: Views and positions of stakeholder groups

The use of genetically modified (GM) crop technology in tackling food security problems and poverty reduction in Africa continues to generate debates over its benefits and safety. Only four countries, South Africa, Sudan, Burkina Faso and Egypt have commercialized GM crops in Africa but controversy surrounds current cultivation of GM maize in Egypt. Our study provides new perspectives on the status, development and regulation of GM crops through examining the views of 305 stakeholders in six African countries across four regions: South Africa, Kenya (East Africa), Egypt and Tunisia (North Africa), Ghana and Nigeria (West Africa), supplemented by interviews with relevant international organizations. The study revealed the challenges leading to the development of biosafety regulatory frameworks and the role of individual stakeholders in the facilitation of GM crops across African countries. This study also revealed that some countries may go through a Fiber–Feed–Food (F3) approach to adopt GM crops where Bt cotton will be adopted first followed by GM crops for livestock feed while undergoing all the necessary assessments before producing GM foods for human consumption. An overwhelming majority of stakeholders placed emphasis on risk analysis (risk assessment and management) in view of limited capacity, lack of scientific expertise and public concern, and encouraged a centralized approach to risk assessment similar to the European Union model of the European Food Safety Authority (EFSA).     

Food environments in Malta: Associations with store size and area-level deprivation

Food environments are potential targets for interventions to reduce obesity prevalence, particularly in island settings that are typically dependent on food imports. This observational study aimed to characterise the availability, quality and price of foods and beverages in a nationally representative sample of grocery stores in Malta using the Nutrition Environment Measures Survey for Stores (NEMS-S) instrument, and to examine the association between area-level density of different types of food stores and the likelihood of children living in these areas being overweight or obese. Fieldwork was carried out between March and May 2014. There was a strong positive correlation between store size and NEMS-S score (p = <0.001), suggesting that smaller grocery stores generally offered a smaller range of products and fewer healthy food/beverage options than larger supermarkets. Across all stores, median prices of certain ‘healthier’ versions of foods were more expensive than their less healthy alternatives. A significant association between risk of childhood overweight, and density of confectionery stores in children’s locality of residence, was found (OR 1.19; 95% CI: 1.04, 1.37). These baseline findings highlight opportunities to improve the food environment in Malta to support more healthful eating, and may be of particular interest to public health practitioners in island settings.

Learning from the implementation of Universal Free School Meals in Scotland using Normalisation Process Theory: Lessons for policymakers to engage multiple stakeholders

In 2014/15, Universal Free School Meals (UFSM) were introduced in Scotland and England for children in their first three years of primary school. This study examined the implementation of UFSM in Scotland using Normalisation Process Theory (NPT), a middle-range theory of implementation, to identify areas of learning for policymakers wishing to introduce or extend similar policies. NPT is predominantly used to evaluate interventions or new technologies in healthcare settings. Qualitative data were collected across Scotland using a case study approach shortly after implementation (n = 29 school-level stakeholders) and in the following school year (n = 18 school-level stakeholders and n = 19 local authority-level stakeholders). Observations of lunchtime in each school were conducted at both timepoints. Data were analysed using a thematic framework approach using NPT constructs and sub-constructs. Results suggested education and catering stakeholders experiences of implementation diverged most around the NPT concepts of coherence, cognitive participation, and reflexive monitoring. Lack of coherence around the purpose and long-term benefits of UFSM appeared to reduce education stakeholders’ willingness to engage with the policy beyond operational issues. In contrast, catering stakeholders identified a direct benefit to their everyday work and described receiving additional resources to deliver the policy. Overall, participants described an absence of monitoring data around the areas of greatest salience for education stakeholders. This study successfully used NPT to identify policy learning around school meals. Policymakers must increase the salience of such intersectoral policies for all relevant stakeholders involved before policy implementation, and plan adequate monitoring to evaluate potential long-term benefits.

Why sustainable and ‘nutritionally correct’ food is not on the agenda: Western Sydney,the moral arts of everyday life and public policy

Within a context of delivering food security into the future, dietary guidelines are being reframed, corporations are replacing unsustainable products, and consumers are being encouraged to become ecological citizens. While there is a growing literature on the food practices of ‘alternative’ consumers, ‘mainstream’ consumers are less well understood. This paper describes qualitative research undertaken in a socio-economically disadvantaged area of Sydney, Australia, which aimed to uncover consumer views towards sustainable and healthy diets. Most participants indicated a discrepancy between their desired and actual behaviours: while they want to support Australian, or local, food producers they gravitate towards cheap and tasty food from ‘anywhere’; and while they associate nutritious food with fresh food, they will buy processed foods which can be less expensive, appeal to children and are prone to less waste. Reflecting mainstream Australian political culture, participants were compromising household food budgets in order to pursue a socially acceptable standard of living (including decent housing, car-reliance). They were also incorporating the pleasure and desires of family members as part of ‘the moral arts of everyday life’. Using social theories of consumption and practice sociology we argue that food choices and practices – easy or not – need to be interpreted as part of the role that consumption plays in political citizenship and moral subjectivity. In the Western Sydney context, food practices are essentially household budget and family nourishment practices rather than nutrition and sustainability practices; a position which is not addressed in the government’s new food policies or wage determination processes.
