A Qualitative Exploration of Predominantly White Non-Hispanic Tennessee WIC Participants’ Food Retail and WIC Clinic Experiences During COVID-19

BackgroundThe novel coronavirus disease 2019 (COVID-19) has widened many existing nutrition disparities. In response, federal nutrition assistance programs have introduced flexibility waivers in programs, including the Special Supplemental Nutrition Program for Women, Infants, and Children (WIC), to rapidly respond to support the nutritional health status of income-eligible participants during COVID-19. Waivers were approved that permitted flexibilities in the WIC food package, WIC vendor guidelines, and WIC clinic experience. The impact of these waivers on WIC participants’ retail and clinic experiences remains unknown.ObjectivesOur aims were to understand the experiences of WIC participants in food retail settings and with WIC clinics during the COVID-19 pandemic and to explore WIC participants’ perceptions of the impact of COVID-19 on their family’s overall health, well-being, and daily lives.DesignWe conducted semi-structured phone interviews between April 30 and May 7, 2020.Participants/settingParticipants were 24 adults in WIC-enrolled families residing in Tennessee.AnalysisUsing grounded theory as the analytical framework, 2 coders completed an iterative, data-driven analytic process within NVivo, version 12. Hierarchical maps, coding matrices, and concept maps were used to aid direct content analysis for theme detection.ResultsFive primary themes emerged, including shopping barriers (existing compounded with new), coping strategies, impact on mental and emotional health, social comparison, and unintended consequences of COVID-19 on WIC families.ConclusionsCOVID-19 created additional barriers to food security among WIC families and negatively affected their health and well-being. To meet the needs of this vulnerable population during and beyond the pandemic, the carryover of WIC flexibilities (ie, physical presence and food package substitution waivers) after COVID-19 may improve the ease of overall program participation.     

Rare Norovirus GIV Foodborne Outbreak,Wisconsin, USA

We report a norovirus GIV outbreak in the United States, 15 years after the last reported outbreak. During May 2016 in Wisconsin, 53 persons, including 4 food handlers, reported being ill. The outbreak was linked to individually prepared fruit consumed as a fruit salad. The virus was phylogenetically classified as a novel GIV genotype.     

Cost-Effectiveness of Food Allergy Interventions in Children: A Systematic Review of Economic Evaluations

ObjectivesTo identify published economic evaluations of interventions aimed at preventing, diagnosing, or treating food allergies in children.MethodsWe examined economic evaluations published from 2000 to 2019. Data analyzed included: food allergy type, study population/setting, intervention/comparator, and economic evaluation details. Quality assessment used reporting and economic modeling checklists. Two reviewers simultaneously undertook article screening, data extraction, and quality assessment.Results17 studies were included: 8 peanut allergy (PA) studies, 8 cow’s milk allergy (CMA) studies, and 1 egg allergy (EA) study. All PA studies reported incremental costs per quality-adjusted life-year gained for diagnostic strategies, management pathways for peanut exposure, and immunotherapies. Immunotherapies rendered inconsistent cost-effectiveness results. CMA studies reported costs per symptom-free day or probability of developing CMA tolerance. Cost-effectiveness of extensively hydrolyzed casein formula for CMA treatment was consistently demonstrated. Early introduction of cooked egg in first year of life dominated all EA prevention strategies. Quality assessment showed average noncompliance for 3.5 items/study (range 0-11) for modeling methods and 3.4 items/study (range 0-8) for reporting quality. Key quality concerns included limited justification for model choice, evidence base for model parameters, source of utility values, and representation of uncertainty.ConclusionRecent cost-effectiveness literature of interventions in PA, CMA, and EA is limited and diverse. Interventions for diagnosis and treatment of CMA and prevention of EA were generally cost-effective; however, results for PA were variable and dependent on effectiveness and utility values used. There is a need to expand economic evaluation of interventions for childhood food allergy and to improve methods and reporting.     

UK food and nutrition security during and after the COVID‐19 pandemic

The COVID‐19 pandemic is a major shock to society in terms of health and economy that is affecting both UK and global food and nutrition security. It is adding to the ‘perfect storm’ of threats to society from climate change, biodiversity loss and ecosystem degradation, at a time of considerable change, rising nationalism and breakdown in international collaboration. In the UK, the situation is further complicated due to Brexit. The UK COVID‐19 Food and Nutrition Security project, lasting one year, is funded by the Economic and Social Research Council and is assessing the ongoing impact of COVID‐19 on the four pillars of food and nutrition security: access, availability, utilisation and stability. It examines the food system, how it is responding, and potential knock on effects on the UK’s food and nutrition security, both in terms of the cascading risks from the pandemic and other threats. The study provides an opportunity to place the initial lessons being learnt from the on‐going responses to the pandemic in respect of food and nutrition security in the context of other long‐term challenges such as climate change and biodiversity loss.     

Resistant Starch Production and Glucose Release from Pre‐Prepared Chilled Food: The SPUD Project

With an increasing prevalence of diabetes worldwide, effective dietary strategies for blood glucose control are crucial. As carbohydrates make up approximately 50% of the diet, it is neither practical nor advisable to avoid them altogether. Most of the carbohydrate in the diet is derived from starch, found in potatoes, pasta, rice and bread. These foods are often processed in some way before consumption, yet little is known about the effects processing, such as chilling and reheating, has on the glycaemic response, particularly when the food is consumed in the context of a mixed meal. This article introduces the SPUD project, a BBSRC DRINC‐funded initiative. Taking the potato as the model carbohydrate, this project will investigate, via in vitro and in vivo studies, the effects of domestic food processing techniques on the glycaemic response. A final study, utilising intrinsically labelled potato and a dual stable isotope methodology, will model glucose flux data to determine the underlying mechanisms of action.     

Recency-Weighted Statistical Modeling Approach to Attribute Illnesses Caused by 4 Pathogens to Food Sources Using Outbreak Data,United States

Foodborne illness source attribution is foundational to a risk-based food safety system. We describe a method for attributing US foodborne illnesses caused by nontyphoidal Salmonella enterica, Escherichia coli O157, Listeria monocytogenes, and Campylobacter to 17 food categories using statistical modeling of outbreak data. This method adjusts for epidemiologic factors associated with outbreak size, down-weights older outbreaks, and estimates credibility intervals. On the basis of 952 reported outbreaks and 32,802 illnesses during 1998–2012, we attribute 77% of foodborne Salmonella illnesses to 7 food categories (seeded vegetables, eggs, chicken, other produce, pork, beef, and fruits), 82% of E. coli O157 illnesses to beef and vegetable row crops, 81% of L. monocytogenes illnesses to fruits and dairy, and 74% of Campylobacter illnesses to dairy and chicken. However, because Campylobacter outbreaks probably overrepresent dairy as a source of nonoutbreak campylobacteriosis, we caution against using these Campylobacter attribution estimates without further adjustment.     

Sexual Contact as Risk Factor for Campylobacter Infection,Denmark

Campylobacteriosis is a disease of worldwide importance, but aspects of its transmission dynamics, particularly risk factors, are still poorly understood. We used data from a matched case-control study of 4,269 men who have sex with men (MSM) and 26,215 controls, combined with national surveillance data on Campylobacter spp., Salmonella spp., and Shigella spp., to calculate matched odds ratios (mORs) for infection among MSM and controls. MSM had higher odds of Campylobacter (mOR 14, 95% CI 10–21) and Shigella (mOR 74, 95% CI 27–203) infections, but not Salmonella (mOR 0.2, 95% CI 0–13), and were less likely than controls to have acquired Campylobacter infection abroad (χ² = 21; p<0.001). Our results confirm that sexual contact is a risk factor for campylobacteriosis and also suggest explanations for unique features of Campylobacter epidemiology. These findings provide a baseline for updating infection risk guidelines to the general population.     

High Case-Fatality Rate for Human Anthrax,Northern Ghana, 2005–2016

The human cutaneous anthrax case-fatality rate is ≈1% when treated, 5%–20% when untreated. We report high case-fatality rates (median 35.0%; 95% CI 21.1%–66.7%) during 2005–2016 linked to livestock handling in northern Ghana, where veterinary resources are limited. Livestock vaccination and access to human treatment should be evaluated.     

Reimagining Nutrition Care and Mealtimes in Long-Term Care

Poor food and fluid intake and subsequent malnutrition and dehydration of residents are common, longstanding challenges in long-term care (LTC; eg, nursing homes, care homes, skilled nursing facilities). Institutional factors like inadequate nutrition care processes, food quality, eating assistance, and mealtime experiences, such as staff and resident interactions (ie, relationship-centered care) are partially responsible and are all modifiable. Evidence-based guidelines on nutrition and hydration for older adults, including those living with dementia, outline best practices. However, these guidelines are not sector-specific, and implementation in LTC requires consideration of feasibility in this setting, including the impact of government, LTC home characteristics, and other systems and structures that affect how care is delivered. It is increasingly acknowledged that interconnected relationships among residents, family members, and staff influence care activities and can offer opportunities for improving resident nutrition. In this special article, we reimagine LTC nutrition by reframing the evidence-based recommendations into relationship-centered care practices for nutrition care processes, food and menus, eating assistance, and mealtime experience. We then expand this evidence into actions for implementation, rating these on their feasibility and identifying the entities that are accountable. A few of the recommended activities were rated as highly feasible (6 of 27), whereas almost half were rated moderate (12/27) and the remainder low (9/27) owing to the need for additional staff and/or expert staff (including funding), or infrastructure or material (eg, food ingredients) investment. Government funding, policy, and standards are needed to improve nutrition care. LTC home leadership needs to designate roles, initiate training, and support best practices. Accountability will result from enforcement of policies through auditing of practice. Further evidence on these desirable nutrition care and mealtime actions and their benefit to residents’ nutrition and well-being is required.     

Associations Among Select State Policies and the Nutritional Quality of Household Packaged Food Purchases in the United States from 2008 Through 2017

BackgroundPolicy interventions are important public health tools because they can reach large numbers of people. State context has been associated with health outcomes, yet few studies have examined the extent to which state-level policies are associated with dietary quality.ObjectivesThe objective of this study was to evaluate whether state policies are associated with the nutritional quality of household packaged food purchases.DesignThis observational study used data from Nielsen Homescan, an open-cohort household panel where participants track purchases, and a combination of state-level food and social safety net policy variables from 2008 through 2017.Participants and settingThis study included 615,634 household-year observations in the United States from 2008 through 2017. Household-year observations were excluded in the case that a household did not make a minimum number of purchases and in the case that they had incorrect geographic information. The final analytic sample was 611,719 household-years.Main outcome measuresStudy outcomes included a set of nutrition-related measures of public health interest, including nutrients of concern (eg, sugar, saturated fat, and sodium) and calories from specific food groups (eg, fruits, nonstarchy vegetables, processed meats, mixed dishes, sugar-sweetened beverages, and desserts and snacks).Statistical analysisThis study used multilevel generalized linear models with state fixed effects on three samples: all households, only households with low income, and only households with low educational attainment.ResultsFew significant associations were found between healthy food retail policies and the nutritional quality of purchases, and mixed associations were found between social safety net policies and lower or higher quality packaged food purchases.ConclusionsLittle evidence was found that state policy context in 2008 through 2017 was associated with the quality of packaged food purchases. However, variation in state policies is increasing over time, warranting future research into the relationship between these policies, the quality of packaged food purchases, and the rest of the diet.
