Background/Objectives: Randomized controlled trials (RCTs) are needed to evaluate the impact of food is medicine (FIM) programs, such as medically tailored groceries (MTGs) to treat hypertension among diverse populations. Partnerships between academic centers’ student-run organizations (SROs) and community-based organizations (CBOs) offer critical safety nets for historically underserved groups, positioning these organizations to effectively undertake FIM programs among populations disproportionately affected by hypertension. We conducted an unblinded pilot RCT whose objectives were to assess the feasibility and acceptability of an SRO-coordinated, CBO-partnered MTGs intervention targeting blood pressure (BP) and food insecurity (FI) in underserved groups. Methods: Adult Black/African American and Hispanic/Latinx patients in Durham, North Carolina, where essential hypertension and FI were randomized (parallel arm, computerized 1:1 ratio) to 12 weeks of home-delivered, hypertension-focused MTGs plus in-person nutrition education sessions with compensation (intervention) versus data collection sessions with compensation (control). We offered transportation, childcare, and home visits to facilitate session attendance. The primary outcomes were the eligibility, enrollment, and retention rates (feasibility), and the survey feedback from the participants and CBO partners (acceptability). The secondary outcomes included the changes in the mean BP and median FI score with associated 95% confidence intervals. Results: Medical record screening identified 1577 eligible participants. Of the 94 reached to confirm eligibility, 77 met the enrollment criteria, and 50 were randomized (82% post-screen eligibility, 65% enrollment). A conventional content analysis of 15 participant surveys and CBO partner feedback affirmed the acceptability, noting intervention components that enhanced the retention (e.g., home delivery, transportation support, home visits). Pre–post analyses of secondary outcomes for 13/25 intervention and 15/25 control participants completing ≥2 sessions ≥2 months apart were performed. The intervention was associated with an average change in systolic BP of −14.2 mmHg (−27.5, −4.5) versus −3.5 mmHg (−11.7, 5.9) in the control group. The FI scores improved by −2 (−2.2, −0.5) in the intervention group and −1 (−1.3, −0.2) in the control group. No adverse events were reported. Conclusions: SRO-CBO partnerships could be feasible and acceptable avenues for conducting FIM trials among underserved populations. This multi-component FIM approach enhanced the study equity by addressing the participants’ disease-related social needs and warrants expansion into a powered RCT. Full article

Due to the convenience of online grocery apps and home delivery, online grocery shopping has become popular in recent years. Globally, consumer behavior has significantly changed the consumption and purchase patterns of online grocery shopping. This study aimed to develop an efficient model for online grocery order fulfillment that both reduces costs and increases supply chain efficiency and sustainability. This study first aimed to develop the current picking model by adopting real-world data from a store in Riyadh, Saudi Arabia. Subsequently, four proposed models were developed to improve the efficiency and sustainability of the online grocery order fulfillment process. The results show a significant improvement in all models over the current picking model. The percentage improvements in fulfillment time per product are as follows: single order picking—8.33%; batch order picking—6.78%; zone order picking—3.08%; and hybrid order picking—13.20%, which combines zone and batch order picking. Retailers and online grocery apps could adopt these models to increase efficiency and sustainability. Also, these models have great potential for future research and improvement by optimizing product placement, in addition to picking methods and picking routes, which are the focus of this study.

We are already more than year away from the pandemic period of COVID-19; its effects and the changes it caused in our lives are becoming ever clearer, and these effects include our food choices and motives. In this study, we investigated changes in food choice motives due to the COVID-19 in college students in Greece; we used the 10 key food motives, namely health, convenience, sensory pleasure, appeal, nutritional quality, moral concerns, weight control, mood and stress, familiarity, price, and shopping frequency and behavior. A sample of 1017 college students answered the questionnaire survey through the Google platform, conducted in January to February 2023. The collected data were analyzed with statistical tools, combining cross and chi-square tests. The students exhibited subtle and very important preferences in terms of health, convenience, weight control, and mood and stress. Food choices related to sensory appeal, nutritional quality, and familiarity were of less importance for the students, similarly to ethical concerns; concern regarding the environmental impact of the food was greater than expected. The motive which continues to be of the highest concern for students before and after the pandemic is price; the students look for value for money in food (88.8%), inexpensiveness (80.7%), and cheapness (78.7%). The shopping frequency and behavior motives, which changed during the pandemic, have now returned to the preferences of the pre-pandemic period, with the purchasing of foods distributed between supermarkets (29%), local grocery stores (37.6%), online (12.3%), and by delivery services (20.4%), weekly or every two weeks. College students’ preference for cooking full meals at home is now very high, reaching 74.4%; students mostly avoid eating at restaurants or eating fast food (only 27%). Our findings indicate that students have already returned to their food choice motives of the period before COVID-19, except with regard to home-cooked food which now ranks higher in their preferences.

Online grocery shopping is an emerging market. It caused visible growth in last mile delivery services, which has resulted in concerns about its external effects (e.g., pollution, land use, congestion). The study outlined in this paper proposes a grocery delivery concept where goods are transported by train to the customer’s nearest station, and then the consumer either picks up the groceries (i.e., click and collect) or the goods are delivered to the customer’s home, or to a locker. The focus of this paper is primarily based on the last mile delivery part of the supply chain (i.e., from the train station to the customer). The land use efficiency and emissions of each delivery concept have been evaluated based on the time-area concept and the Handbook Emission Factors for Road Transport (HBEFA 4.1), respectively. This large-scale simulation considers every household in Switzerland with various levels of demand and supermarket network densities. Two machine learning techniques (i.e., random forest and decision tree) have been used to categorise all neighbourhoods within Switzerland based on the best delivery method in terms of emissions and land efficiency. The results show that, depending on the scenarios (e.g., 10 or 100% of the households taking part), home delivery can be better for 76–89% of these communities when compared with a click and collect option based on their land use efficiency.

Forecast growth in e-commerce home-delivery demand provides retailers with opportunities for expansion and increased levels of investment. To maximise these growth opportunities, retailers face operational and logistical challenges related to order fulfilment and the last mile. In contrast to other sectors, many grocers operate a store-based delivery model rather than a separate distribution channel. Under this model, orders are picked from store shelves and store-based fleets of delivery vehicles are used for last-mile fulfilment (delivery to the consumers’ home). With very rare access to commercial data from Sainsbury’s, the second largest grocer in Great Britain, we analyse the geographical variations of online groceries fulfilment capacity at store, region, and rural–urban geography levels, exploring the interrelated impact of capacity constraints related to storage and delivery in limiting the further growth of these services. The spatial extent of delivery service areas are found to considerably vary between stores and the existing store network presents barriers to further capacity expansion in some regions. We argue factors associated with the last mile are an important capacity constraint/enabler in the e-groceries sector and suggest that the effective expansion of these services requires further research into online service area delineation to maximise delivery efficiency and capacity. The approach used here is readily transferable to other online service delivery providers in both GB and elsewhere. Full article

The steadily growing popularity of grocery home-delivery services is most likely based on the convenience experienced by its customers. However, the perishable nature of the products imposes certain requirements during the delivery process. The customer must be present when the delivery arrives so that the delivery process can be completed without interrupting the cold chain. Therefore, the grocery retailer and the customer must mutually agree on a time window during which the delivery can be guaranteed. This concept is referred to as the attended home delivery (AHD) problem in the scientific literature. The phase during which customers place orders, usually through a web service, constitutes the computationally most challenging part of the logistical processes behind such services. The system must determine potential delivery time windows that can be offered to incoming customers and incrementally build the delivery schedule as new orders are placed. Typically, the underlying optimization problem is a vehicle routing problem with a time windows. This work is concerned with a case given by an international grocery retailer’s online shopping service. We present an analysis of several efficient solution methods that can be employed to AHD services. A framework for the operational planning tools required to tackle the order placement process is provided. However, the basic framework can easily be adapted to be used for many similar vehicle routing applications. We provide a comprehensive computational study comparing several algorithmic strategies, combining heuristics utilizing local search operations and mixed-integer linear programs, tackling the booking process. Finally, we analyze the scalability and suitability of the approaches. Full article

During the COVID-19 pandemic, the government in Kuwait implemented public health measures to control the spread of the virus. However, despite the importance of these restrictions, normal activities related to purchasing of groceries, concerns related to food safety, and overall uncertainty may have influenced food behaviors and food consumption. Hence, the study investigates the impact of COVID-19 on food purchasing behaviors, eating behaviors, and the perception of food safety and security among residents in Kuwait. A cross-sectional study was carried out using self-administered questionnaires between 28 July 2020 and 31 August 2020 during the COVID-19 pandemic in Kuwait. A total of 841 respondents participated in the study. The study identified several changes in food purchasing behaviors, eating behaviors, food consumption, and consumers perceptions on food safety during the pandemic. The closures, restrictions, and changes in food purchasing evidently influenced individual’s eating behaviors. Largely, participants were found to (i) change their food purchasing behavior (74%); (ii) opt for online food delivery services (42.8%); (iii) purchase long-shelf-life foods (e.g., canned food and dry staples) (76%); (iv) consume more meals at home (76%); and (v) follow public health measures to reduce the spread of the virus and ensure their safety (98%). This study indicates that individuals during times of uncertainty and stress change their food purchasing behaviors, food consumption habits, and follow guidelines and recommendations. These findings may help public health initiatives to focus on raising awareness about the importance of health, wellbeing, and nutrition during times of crises. Full article

E-grocery is becoming more and more popular, involving both pure e-commerce players and physical stores in its development and sales. As a consequence, the last mile delivery model has been heavily modified, with ambiguous final impact on the environment. This paper identifies the key elements germane to e-grocery (demand and supply), discusses e-grocery development and investigates the challenges ahead. In more detail, it presents the results of a stated preference survey on consumers’ channel choices for the grocery market. The survey was carried out in Shanghai (China) in order to investigate different purchase attributes, such as product and delivery service price, product range, lead time, time window and travel time. The paper identifies heterogeneous reactions to alternative service configurations, which allows to estimate market shares for e-grocery, with the in-store option as a reference. Policy implications and operational solutions to improve the sustainability of this renewed last mile delivery model are thus proposed. Full article

Evidence of short-term impacts of the coronavirus disease 2019 (COVID-19) pandemic on family life is emerging. Continued research can shed light on potential longer-term impacts. An online survey of U.S. parents with 4- to 8-year-old children (n = 1000) was administered in October 2020. The survey examined parent-reported impacts of COVID-19 on lifestyle (e.g., work, child-care, grocery shopping), as well as current family food acquisition and eating behaviors (e.g., cooking, restaurant use). Descriptive statistics were calculated, incorporating sampling weights based on sociodemographics. In terms of COVID-19 impacts, parents reported increases in working from home, decreased work hours, and increased child care and instruction, with most children attending school or receiving care at home. Parents reported increased home cooking and online grocery shopping; only 33% reported increased take-out or delivery from restaurants. About half of parents reported that their child dined at restaurants, 62% reported getting take-out, and 57% reported delivery from restaurants at least 2–3 times per month. About half viewed dining at restaurants as safe, while take-out and delivery were seen as safe by around three-quarters. Approximately two-thirds reported recent food insecurity. These nationally-representative results illustrate possible longer-lasting shifts in family life, with the potential to impact health and well-being. Sociodemographic differences and research and policy implications are discussed. Full article

Increases in the number of food outlets have been proposed as a key factor driving obesity. This study aimed to investigate the association between the densities of food establishments serving meals (excluding supermarkets and grocery stores), with body mass index (BMI), waist to hip ratio (WHR) and percentage of body fat among middle-aged adults in the UK. BMIs, WHR, %fat and socioeconomic factors were obtained from 456,079 individuals from the UK Biobank and averaged across 923 postcode districts (PD). The number of Fast-Food Restaurants (FFRs), Full-Service Restaurants (FSRs), delivery shops, takeaways, fish and chip shops, pubs and cafes were also obtained for each PD. We adjusted the obesity measures for deprivation level, education, employment, ethnicity, household size, household income and age. After adjustment, the density of fish and chip shops (per 1000 population) was positively associated with BMI and %fat for both sexes (males: BMI converted (exponentiated coefficient) β = 0.5, R² = 4.14%, p < 0.0001; %fat converted β = 0.8, R² = 3.32%, p < 0.0001; females: BMI converted β = 0.9, R² = 5.31%, p < 0.0001; %fat converted β = 1.4 R² = 4.65%, p < 0.0001). The densities of FFRs and delivery shops (per 1000 population) were not related to the adjusted obesity measures among males and females, except BMI in males where FFRs were significantly negatively associated. The densities (per 1000 population) of FSRs, pubs, cafes and total food outlets were all significantly inversely related to the obesity measures for both sexes. The number of fish and chip shops per 1000 individuals was significantly positively associated with obesity in middle-aged adults in the UK. A negative association between the other types of food outlet densities and the measures of obesity suggests access to such establishments is not a major driver of obesity. This is potentially because the food supplied at such establishments is not significantly less healthy than what is eaten elsewhere including at home (and may even be better). Paying attention only to fast food and/or full-service restaurants in intervention policy will likely not be effective. Policy intervention should potentially focus on the numbers of fish and chip shops and the deep-fried food served in such restaurants. Full article

The objective of this study was to create/test a social marketing campaign to increase fruit/vegetable (FV) intake within Oregon Supplemental Nutrition Assistance Program (SNAP) eligible families. Focus groups (n = 2) and pre/post campaign phone surveys (n = 2082) were conducted in intervention counties (IC) and one control county. Participants were female (86%–100%) with 1–2 children at home. Mean FV intake/without juice was 3.1 servings/day; >50% preferred the Internet for delivery of healthy eating information. Participants reported time/financial burdens, low household FV variety and desirability of frozen/canned FV, and acceptance of positive messages. A Food Hero (FH) campaign was created/delivered daily August–October 2009 to mothers through multiple channels (e.g., grocery stores, online, educators). Results showed that the IC had better FH name recall (12%) and interpretation of intended messages (60%) vs. control (3%, 23%, respectively). Compared to controls, the IC were less likely to report healthy food preparation as time consuming or a FV rich diet expensive, and it was easier to get their family to eat fruit. Results did not vary based on county/household characteristics. The FH campaign increased FH awareness and positive FV beliefs. A longer campaign with FV assessments will increase understanding of the target audience, and allow for campaign refinement. Full article
