The Role of Social Issues on Food Procurement among Corner Store Owners and Shoppers.

OBJECTIVE: We assessed corner store shopper and owner perceptions, barriers, and enablers related to food procurement in a sample of neighborhood corner stores where over 50% of families are SNAP eligible. DESIGN: We conducted semi-structured interviews to identify inventory stocking, shopping and marketing approaches, and perspectives on healthy eating. PARTICIPANTS: Five corner store owners and 20 corner store shoppers. RESULTS: Corner store owners: 1) did not feel as though they belonged to the community where their corner store was located; 2) had difficulty in becoming authorized WIC retailers because of the perceived complexity of the process, and 3) stated tobacco products and hot food items are their best-selling items; fruits and vegetables were perceived as unmarketable. Corner store shoppers preferred shopping at local corner stores because: 1) lack of transportation made corner stores easier to access than full-service grocery stores; 2) hot foods are readily available and inexpensive; 3) some home kitchens lacked an oven or stovetop for meal preparation; 4) they need to shop daily for children or other family members. CONCLUSIONS: Social issues such as housing quality, corner store owner sense of community, and acculturation should be addressed when considering food environment in limited resource communities.

Physician Use of Electronic Health Records in Obesity Management.

OBJECTIVE: To assess Wisconsin physician knowledge, attitudes, and practices in obesity management. METHODS: The Wisconsin Medical Society distributed an e-mail survey to 12,372 members with questions on obesity causes, barriers to documentation, and training in obesity management. RESULTS: A total of 590 surveys (4.7%) were completed. Physicians had an accurate fund of knowledge. Reasons given for failure to document obesity were lack of reimbursement, lack of effective treatment, and discomfort in discussing obesity. Only 14% of responding physicians were optimistic about their patients achieving sustained weight loss and only 7% believed they have been successful at treating obesity. Training was infrequent in obesity management. CONCLUSIONS: Survey respondents indicated that additional training and effective tools would help treat obesity. Strategies should be developed that improve physician effectiveness in obesity management.

Physically active, low-income African American women: an exploration of activity maintenance in the context of sociodemographic factors associated with inactivity.

Increasing physical activity among low-income African American women is an important target for addressing racial and economic disparities in chronic conditions and related risk factors. While barriers to physical activity for women have been examined empirically, successful strategies for navigating those barriers among physically active, low-income women have not been thoroughly explored. Informed by grounded theory, we conducted in-depth individual interviews between 2007-2010 with 14 low-income African American women who were physically active at nationally recommended levels for one year or more. We analyzed the data using thematic analysis techniques. Key themes emerged in three main categories: motivation for maintaining active lifestyle, strategies for maintaining physical activity, and challenges to maintaining physical activity. Important motivations included getting or staying healthy, social connections, and gratification. Two planning strategies emerged: flexibility and freedom. Critical challenges included financial constraints, physical strain and history of sedentary relapse. The motivations, strategies and challenges reported by low-income African American women who successfully maintained an active lifestyle provided important information for developing effective health promotion strategies for their inactive and underactive counterparts. A qualitative, asset-based approach to physical activity research contributes rich data to bridge the gap between epidemiological knowledge and community health improvement.

Game-based learning to improve diagnostic accuracy: a pilot randomized-controlled trial.

OBJECTIVES: Perform a pilot study of online game-based learning (GBL) using natural frequencies and feedback to teach diagnostic reasoning. METHODS: We conducted a multicenter randomized-controlled trial of computer-based training. We enrolled medical students, residents, practicing physicians and nurse practitioners. The intervention was a 45 min online GBL training vs. control education with a primary outcome of score on a scale of diagnostic accuracy (composed of 10 realistic case vignettes, requesting estimates of probability of disease after a test result, 0-100 points total). RESULTS: Of 90 participants there were 30 students, 30 residents and 30 practicing clinicians. Of these 62 % (56/90) were female and 52 % (47/90) were white. Sixty were randomized to GBL intervention and 30 to control. The primary outcome of diagnostic accuracy immediately after training was better in GBL (mean accuracy score 59.4) vs. control (37.6), p=0.0005. The GBL group was then split evenly (30, 30) into no further intervention or weekly emails with case studies. Both GBL groups performed better than control at one-month and some continued effect at three-month follow up. Scores at one-month GBL (59.2) GBL plus emails (54.2) vs. control (33.9), p=0.024; three-months GBL (56.2), GBL plus emails (42.9) vs. control (35.1), p=0.076. Most participants would recommend GBL to colleagues (73 %), believed it was enjoyable (92 %) and believed it improves test interpretation (95 %). CONCLUSIONS: In this pilot study, a single session with GBL nearly doubled score on a scale of diagnostic accuracy in medical trainees and practicing clinicians. The impact of GBL persisted after three months.

Do residents of food deserts express different food buying preferences compared to residents of food oases? A mixed-methods analysis.

BACKGROUND: Many people lack access to food stores that provide healthful food. Neighborhoods with poor supermarket access have been characterized as "food deserts" (as contrast with "food oases"). This study explored factors influencing food buying practices among residents of food deserts versus food oases in the city of Boston, USA. METHODS: We used the mixed-methods approach of concept mapping, which allows participants to identify, list, and organize their perceptions according to importance. Resulting maps visually illustrate priority areas. RESULTS: Sixty-seven low-income adults completed the concept mapping process that identified 163 unique statements (e.g. relating to affordability, taste, and convenience) that influence food buying practices. Multivariate statistical techniques grouped the 163 statements into 8 clusters or concepts. Results showed that average cluster ratings and rankings were similar between residents of food deserts and food oases. CONCLUSIONS: The implication of this study pertains to the importance of community resources and emergency food assistance programs that have served to minimize the burden associated with hunger and poor food access among low-income, urban populations.

When is enteral nutrition indicated?

Enteral nutrition (EN) is a vital component of nutrition around the world. EN allows for delivery of nutrients to those who cannot maintain adequate nutrition by oral intake alone. Common questions regarding EN are when to initiate and in what scenarios it is safe. The answers to these questions are often complex and require an evidence-based approach. The Board of Directors of the American Society for Parenteral and Enteral Nutrition (ASPEN) established an Enteral Nutrition Committtee to address the important questions surrounding the indications for EN. Consensus recommendations were established based on eight extremely clinically relevant questions regarding EN indications as deemed by the Enteral Nutrition Committee. These consensus recommendations may act as a guide for clinicians and stakeholders on difficult questions pertaining to indications for EN. This paper was approved by the ASPEN Board of Directors.

Accuracy of Water Delivery in Enteral Nutrition Pumps.

BACKGROUND: Adequate delivery of both enteral formula and water in patients receiving enteral nutrition (EN) is critical. Pump accuracy has been identified as a factor impeding enteral formula delivery; however, rarely is enteral water delivery investigated. The purpose of this study was to explore accuracy of delivering 1 L of water by EN pumps using different flush volumes and hang heights. METHODS: Three EN pumps were used in vitro to flush 1 L of water at 50 mL every hour for 20 hours (50 mL, 20 times per day) and 500 mL every 4 hours for 8 hours (500 mL, 2 times per day) at 0 in. and 18 in. (or 45.72 cm) hang heights. Fifteen runs were conducted at each volume and hang height per pump. Actual delivered enteral water, remaining volume in enteral feeding bags, and volume reported per pump were recorded. RESULTS: Hang height of 18 in. delivered a mean 3.91% (95% CI, 3.25-4.57) more water than bags hung at 0 in. (P < .0005). When delivering water in 500 mL increments, 1.57% (95% CI, 0.92-2.23) more water was delivered than when delivered in 50 mL increments (P < .005). CONCLUSION: Appropriate hang height recommendations improve enteral water delivery in patients receiving EN. The most accurate setting was 500 mL at 18 in., resulting in accurate water delivery in 97.8% of runs, whereas 50 mL at 0 in. delivered accurately 17.8% of the time. Appropriate bag hang height and water delivery volume is critical to maintain hydration status of patients receiving EN.

Insights about interventions to address food insecurity in adults with type 2 diabetes: Valuable lessons from the stories of African Americans living in the inner city.

OBJECTIVES: This qualitative study aimed to gain insight from the perspectives of food insecure African Americans living in an inner city regarding important diabetes intervention strategies and components. METHODS: Using a grounded theory approach, two focus groups (totaling 16 individuals) were conducted in Milwaukee, Wisconsin. Purposive, convenience sampling was used to identify food insecure adults with diabetes. Questions were asked using a moderator guide to explore challenges and barriers to managing diabetes within the context of food insecurity, and facilitators or resources that helped participants improve diabetes management. Questions were open ended and followed by probes asking for additional perspectives and personal experiences related to the overarching topic, and questions asking to clarify statements. RESULTS: Overarching concepts and themes specific to possible interventions discussed during the focus groups included group education, peer support, access to community resources and programs, stress management, and faith-based programs as desired intervention outcomes. CONCLUSIONS: Key findings from the current study show that inner-city African Americans with diabetes desire interventions that foster social and community support systems. PRACTICE IMPLICATIONS: Given this insight, more robust and comprehensive interventions are needed to account for the multifaceted experience of food insecurity and diabetes within the inner-city environment.

Exploring the Lived Experience of Food Insecure African Americans with Type 2 Diabetes Living in the Inner City.

PURPOSE: Despite evidence that food insecure African Americans with type 2 diabetes are at particularly high risk for poor health outcomes, there is currently a lack of information on their lived experience. This qualitative study aimed to identify challenges, facilitators, and barriers to effective diabetes care for food insecure African Americans with type 2 diabetes residing in an inner city. METHODS: In fall 2018, we conducted two focus groups attended by a total of 16 food insecure adults with type 2 diabetes residing in the inner city of Milwaukee, Wisconsin. A standardized moderator guide included questions to explore the role of food insecurity in managing diabetes, and facilitators that improve diabetes management within the context of food insecurity. Focus groups were audio recorded and recordings were transcribed by a professional transcription service. A grounded theory approach was used for analysis. RESULTS: Six major challenges existed at the individual level (diet/nutrition, exercise, diabetes knowledge and skills, complications from diabetes, a family history of diabetes, and a preoccupation with food). Five major barriers and facilitators existed both internally and externally to the individuals (access to food, medications, stress, cost of health-related needs and religion/spirituality). CONCLUSIONS: This study identified multiple challenges, barriers, and facilitators to effective care for food insecure African American adults with type 2 diabetes. It is imperative to incorporate this understanding in future work by using an ecological approach to investigate strategies to address food insecurity beyond a singular focus on access to food.

Quantifying the Influence of Individual, Community, and Health System Factors on Quality of Life Among Inner-City African Americans With Type 2 Diabetes.

PURPOSE: The purpose of this study is to examine the association of individual, community, and health system factors on quality of life among inner-city African Americans with type 2 diabetes. METHODS: Primary data from a cross-sectional study with a community sample of 241 inner-city African Americans with type 2 diabetes were analyzed. Paper-based surveys were administered in which the SF-12 was used to capture the physical component (PCS) and mental component (MCS) of quality of life. Four regression approaches (sequential, stepwise with backward and forward selection, and all possible subsets regression) were used to examine the influence of individual, community, and health system factors on PCS and MCS after adjusting for relevant covariates using a conceptual framework. RESULTS: In fully adjusted models, having less than a high school education and having major depression were associated with lower quality-of-life scores for MCS across all 4 regression approaches. Being employed was positively associated with better quality-of-life scores for PCS across all 4 regression approaches. PCS was higher across all 4 regression approaches for those reporting a history of trauma. At the health systems level, usual source of care was associated with better PCS across 3 regression approaches. CONCLUSIONS: These results highlight key factors that influence quality of life among inner-city African Americans with type 2 diabetes that could be targets for interventions in this population. However, additional research is needed to understand existing pathways that may be driving many of these relationships.

Relative Contribution of Individual, Community, and Health System Factors on Glycemic Control Among Inner-City African Americans with Type 2 Diabetes.

BACKGROUND: Health disparities disproportionately impact inner-city African Americans; however, limited information exists on the contribution of individual, community, and health system barriers on diabetes outcomes in this population. METHODS: A cross-sectional study collected primary data from 241 inner-city African Americans with type 2 diabetes. A conceptual framework was used to specify measurements across the individual level, such as age and comorbidities; community level, such as neighborhood factors and support; and health system level such as access, trust, and provider communication. Based on current best practices, four regression approaches were used: sequential, stepwise with forward selection, stepwise with backward selection, and all possible subsets. Variables were entered in blocks based on the theoretical framework in the order of individual, community, and health system factors and regressed against HbA1c. RESULTS: In the final adjusted model across all four approaches, individual-level factors like age (ß = - 0.05; p < 0.001); having 1-3 comorbidities (ß = - 2.03; p < 0.05), and having 4-9 comorbidities (ß = - 2.49; p = 0.001) were associated with poorer glycemic control. Similarly, male sex (ß = 0.58; p < 0.05), being married (ß = 1.16; p = 0.001), and being overweight/obese (ß = 1.25; p < 0.01) were associated with better glycemic control. Community and health system-level factors were not significantly associated with glycemic control. CONCLUSION: Individual-level factors are key drivers of glycemic control among inner-city African Americans. These factors should be the key targets for interventions to improve glycemic control in this population. However, community and health system factors may have indirect pathways to glycemic control that should be examined in future studies.

ASPEN Report on Nutrition Support Practice Processes With COVID-19: The First Response.

Coronavirus disease 2019 (COVID-19) has changed nutrition care processes in hospitals and in the home setting. This paper summarizes clinician reports on these changed processes, including overall nutrition care, nutrition assessment, enteral nutrition and parenteral nutrition care steps, and food and oral supplement delivery. Also included are teaching, logistics, and personnel issues around changes in the work environment. Use of safe, standardized, evidence-based processes in the face of altered care patterns is critical.

Lowering the impact of food insecurity in African American adults with type 2 diabetes mellitus (LIFT-DM) - Study protocol for a randomized controlled trial.

BACKGROUND: There is strong evidence that disparities in the burden of diabetes exist by both race and poverty. Food insecurity, or an inability to or limitation in accessing nutritionally adequate food, is an important modifiable social determinant of health, particularly in adults with chronic disease. African Americans are more likely to be diagnosed with diabetes and more likely than whites to be food insecure. METHODS: We describe a 4-year ongoing randomized controlled trial, which will test the separate and combined efficacy of monthly food vouchers and monthly food stock boxes layered upon diabetes education in improving glycemic control in low income, food insecure, African Americans with type 2 diabetes mellitus using a 2 × 2 factorial design. Three hundred African American adults with clinical diagnosis of diabetes and HbA1c ≥ 8% will be randomized into one of four groups: 1) diabetes education alone; 2) diabetes education plus food vouchers; 3) diabetes education plus stock boxes; and 4) diabetes education plus combined food vouchers and stock boxes. Our primary hypothesis is: among low-income, food insecure, African Americans with type 2 diabetes, those receiving diabetes education enhanced with food supplementation (food vouchers alone, stock boxes alone, or combination) will have significantly greater reduction in HbA1c at 12 months compared to those receiving diabetes education only. DISCUSSION: Results from this study will yield valuable insight currently lacking on how best to design and deliver diabetes interventions to low-income, food insecure, African Americans with diabetes that takes into account both clinical and social determinants of health. TRIAL REGISTRATION: This study was registered on November 29, 2019 with the United States National Institutes of Health Clinical Trials Registry (ClinicalTrials.gov identifier# NCT04181424).

ASPEN Consensus Recommendations for Refeeding Syndrome.

INTRODUCTION: In the spring of 2017, the American Society for Parenteral and Enteral Nutrition (ASPEN) Parenteral Nutrition Safety Committee and the Clinical Practice Committee convened an interprofessional task force to develop consensus recommendations for identifying patients with or at risk for refeeding syndrome (RS) and for avoiding and managing the condition. This report provides narrative review and consensus recommendations in hospitalized adult and pediatric populations. METHODS: Because of the variation in definitions and methods reported in the literature, a consensus process was developed. Subgroups of authors investigated specific issues through literature review. Summaries were presented to the entire group for discussion via email and teleconferences. Each section was then compiled into a master document, several revisions of which were reviewed by the committee. FINDINGS/RECOMMENDATIONS: This group proposes a new clinical definition, and criteria for stratifying risk with treatment and screening strategies. The authors propose that RS diagnostic criteria be stratified as follows: a decrease in any 1, 2, or 3 of serum phosphorus, potassium, and/or magnesium levels by 10%-20% (mild), 20%-30% (moderate), or >30% and/or organ dysfunction resulting from a decrease in any of these and/or due to thiamin deficiency (severe), occurring within 5 days of reintroduction of calories. CONCLUSIONS: These consensus recommendations are intended to provide guidance regarding recognizing risk and identifying, stratifying, avoiding and managing RS. This consensus definition is additionally intended to be used as a basis for further research into the incidence, consequences, pathophysiology, avoidance, and treatment of RS.

Pathways connecting neighborhood influences and mental well-being: socioeconomic position and gender differences.

Few studies have explored how participant socioeconomic position (SEP) and gender is related to perceptions of the pathways connecting neighborhood influences and mental well-being. This research used the concept mapping method, an intensive structured conceptualization process that produces pictorial views of how concepts are connected and interrelated. Thirty-six low and non-low SEP men and women from Toronto, Canada participated in the concept mapping sessions. One hundred and twenty unique neighborhood characteristics were felt to be related to mental well-being and those items were grouped into six distinct clusters. Notable differences in cluster importance by participant SEP status were found. While no overall differences were observed for males verses females, further stratification by both participant SEP and gender suggested that gendered perceptions are not uniform. Participant-created diagrams illustrated how the cluster domains are related to each other and to good mental well-being. These findings are important for uncovering the mechanisms by which neighborhoods differentially affect the mental health of residents from different SEPs and genders.

Predictive equations for energy needs for the critically ill.

Nutrition may affect clinical outcomes in critically ill patients, and providing either more or fewer calories than the patient needs can adversely affect outcomes. Calorie need fluctuates substantially over the course of critical illness, and nutrition delivery is often influenced by: the risk of refeeding syndrome; a hypocaloric feeding regimen; lack of feeding access; intolerance of feeding; and feeding-delay for procedures. Lean body mass is the strongest determinant of resting energy expenditure, but age, sex, medications, and metabolic stress also influence the calorie requirement. Indirect calorimetry is the accepted standard for determining calorie requirement, but is unavailable or unaffordable in many centers. Moreover, indirect calorimetry is not infallible and care must be taken when interpreting the results. In the absence of calorimetry, clinicians use equations and clinical judgment to estimate calorie need. We reviewed 7 equations (American College of Chest Physicians, Harris-Benedict, Ireton-Jones 1992 and 1997, Penn State 1998 and 2003, Swinamer 1990) and their prediction accuracy. Understanding an equation's reference population and using the equation with similar patients are essential for the equation to perform similarly. Prediction accuracy among equations is rarely within 10% of the measured energy expenditure; however, in the absence of indirect calorimetry, a prediction equation is the best alternative.

Duration-Response of Light-Intensity Physical Activity and Glucose Dynamics in Older Adults.

BACKGROUND: Older adults spend 30% of their day in light-intensity physical activity (LPA). This study was designed to determine if increasing the proportion of time spent in LPA would affect glucose control. METHODS: Older adults (N = 9) completed four 3-hour treatment conditions consisting of a seated control and 3 randomized conditions: (1) 20% time spent in continuous LPA, 80% seated; (2) 40% time spent in continuous LPA, 60% seated; and (3) 60% time spent in continuous LPA, 40% seated. Energy expenditure was measured continuously, and glucose was measured prior to mixed-meal ingestion and hourly thereafter. Glucose area under the curve was compared between conditions using Friedman test. RESULTS: There was a significant difference in glucose area under the curve by time spent in LPA (P < .001); specifically, between the seated and 60% LPA (mean difference = 35.0 [24.6] mg/dL, P = .01), seated and 40% LPA (mean difference = 25.2 [11.8] mg/dL, P = .03), seated and 20% LPA (mean difference = 17.8 [22.5] mg/dL, P = .03), 20% LPA and 60% LPA (mean difference = 17.2 [22.5] mg/dL, P = .01), and 40% LPA and 60% LPA (mean difference = 9.8 [7.3] mg/dL, P = .01). CONCLUSION: These results provide experimental evidence to the importance LPA has on metabolic health. If older adults who already spend, on average, about 3 hours per day in LPA, further increase their LPA, they could see benefit to glucose control.

Hang Height of Enteral Nutrition Influences the Delivery of Enteral Nutrition.

PURPOSE: Adequate enteral nutrition (EN) delivery to critically ill patients is difficult to achieve. Given the large number of unpreventable influences affecting adequate caloric intake, further research on preventable influences of adequate EN administration is warranted. The purpose of this study was to evaluate whether hang height of EN formula, formula viscosity, or flow rate influences pump accuracy and formula delivery. METHODS: Formulas of varying viscosities (1.0, 1.5, and 2.0 kcal/mL) were infused at different hang heights (0, 6, 12, and 18 inches) and rates (20, 40, and 80 mL/h). The mean percent difference and the bias between the programmed volume, volume reported, and volume delivered were calculated for the different hang heights, formula compositions, and infusion rates studied. RESULTS: For all prespecified hang heights and infusion rates, the volume delivered was less than the programmed volume and volume reported; the mean percent difference increased as the hang height decreased. The volume was overestimated for both the programmed volume (14.4% ± 5.5%) and volume reported (12.9% ± 6.7%) compared with volume delivered. The overestimation bias was significantly influenced by differences in hang height as well as type of formula (P < .0001, each) but not by rate of delivery (P = .4633 for programmed volume and .8411 for volume reported). CONCLUSIONS: Measures should be taken in clinical practice to ensure adequate hang height of EN. Appropriate hang height of EN may result in more accurate delivery of nutrition provisions to the critically ill patient and subsequently reduce complications related to underfeeding.

Parenteral Nutrition Electrolyte Abnormalities and Associated Factors Before and After Nutrition Support Team Initiation.

BACKGROUND: Studied since the 1940s, refeeding syndrome still has no universal definition, thus making comparison of studies difficult. Negative outcomes (eg, metabolic abnormalities) may occur with the use of specialized nutrition, such as parenteral nutrition (PN). Less than half of medical institutions have a nutrition support team (NST) managing PN. Interdisciplinary team management of PN may reduce negative outcomes of PN. The objective of this study was to show the value of the NST by measuring differences in PN variables, especially electrolyte abnormalities (EAs), before and after NST initiation at a large medical center and to identify factors associated with EAs among adult subjects receiving PN. MATERIALS AND METHODS: During this retrospective study, computerized medical charts (N = 735) from 2007-2010 were reviewed for electrolyte changes (particularly potassium, magnesium, and phosphorus) the first 3 days following PN initiation in hospitalized adults. Changes in EAs with other variables were compared before and after NST implementation. Equivalent samples sizes were collected to better evaluate the impact of the team. RESULTS: Following the implementation of the NST, fewer EAs were seen in PN patients (53%; χ2  = 10.906, P = .004); significantly less potassium, phosphorus, and magnesium intravenous piggyback supplementation (88.8% vs 94%; χ2  = 5.05, P = .026) was used; and mortality within 30 days of PN cessation was significantly less (12.7% vs 10.6%, P = .012). CONCLUSION: Our study complements existing research, finding that an NST was associated with a decreased occurrence of EAs and mortality in the hospitalized adult receiving PN.
