The impact of financial incentives and restrictions on cyclical food expenditures among low-income households receiving nutrition assistance: a randomized controlled trial.

BACKGROUND: The Supplemental Nutrition Assistance Program (SNAP) is the largest anti-hunger program in the United States. Two proposed interventions to encourage healthier food expenditures among SNAP participants have generated significant debate: financial incentives for fruits and vegetables, and restrictions on foods high in added sugar. To date, however, no study has assessed the impact of these interventions on the benefit cycle, a pattern of rapid depletion of SNAP benefits that has been linked to worsening nutrition and health outcomes over the benefit month. METHODS: Low-income households not currently enrolled in SNAP (n = 249) received benefits every 4 weeks for 12 weeks on a study-specific benefit card. Households were randomized to one of four study arms: 1) incentive (30% incentive for fruits and vegetables purchased with study benefits), 2) restriction (not allowed to buy sugar-sweetened beverages, sweet baked goods, or candy using study benefits), 3) incentive plus restriction, or 4) control (no incentive or restriction). Weekly household food expenditures were evaluated using generalized estimating equations. RESULTS: Compared to the control group, financial incentives increased fruit and vegetable purchases, but only in the first 2 weeks after benefit disbursement. Restrictions decreased expenditures on foods high in added sugar throughout the benefit month, but the magnitude of the impact decreased as the month progressed. Notably, restrictions mitigated cyclical expenditures. CONCLUSIONS: Policies to improve nutrition outcomes among SNAP participants should consider including targeted interventions in the second half of the month to address the benefit cycle and attendant nutrition outcomes.

Designing online grocery stores to support healthy eating for weight loss.

OBJECTIVES: The current study aimed to identify features to include in online grocery stores to support healthful food purchasing by those striving to lose weight. DESIGN: A Value Proposition Design approach was used to gain shopper insights, devise potential online grocery store features and obtain feedback on these features. SETTING: Telephone interviews were conducted to gain insight into shoppers' needs and perceptions. Results were used by the research team to identify potential online grocery shopping features that may support healthful purchase decisions, and interviews were conducted with a different sample of shoppers to gather feedback on features. PARTICIPANTS: Insight (n 25) and feedback (n 25) interviews were conducted with convenience samples of adults trying to lose weight. RESULTS: Participants were primarily female, white, college educated and with obesity or overweight. Online grocery features devised by the research team based on findings from the insight interviews included (1) shopping cart nutrition rating tool; (2) healthy meal planning tool; (3) interactive healthy eating inspiration aisle and (4) healthy shopping preference settings option. Findings from the feedback interviews indicated that the healthy meal planning tool, healthy shopping preference settings option and shopping cart nutrition rating tool features were positively rated by most participants. CONCLUSIONS: There are multiple features grocers should consider including in their online stores to attract and support customers striving to eat healthy for weight loss.

Trends in cyclical food expenditures among low-income households receiving monthly nutrition assistance: results from a prospective study.

OBJECTIVE: Supplemental Nutrition Assistance Program (SNAP) benefits are rapidly depleted after distribution. This phenomenon, known as the benefit cycle, is associated with poor nutrition and health outcomes. However, to date, no study has evaluated trends in food expenditures before and after households receive benefits using prospective data, and whether these trends vary by household characteristics. DESIGN: Generalised estimating equations were used to model weekly household food expenditures during baseline (pre-benefit) and intervention months by vendor (restaurants and food retailers). Food retailer expenditures were further evaluated by food category (fruits and vegetables and foods high in added sugar). All expenditures were evaluated by household composition, demographics and economic means. SETTING: Minneapolis-St. Paul, Minnesota, metropolitan area. PARTICIPANTS: Low-income households (n 249) enrolled May 2013-August 2015. RESULTS: Weekly food retailer expenditures did not vary during baseline (pre-benefit), but demonstrated a cyclical pattern after households received benefits across all household characteristics and for both food categories, particularly for fruits and vegetables. Households with greater economic resources spent more throughout the month compared with those with fewer resources. Households with lower food security status experienced more severe fluctuations in spending compared with more food secure households. CONCLUSIONS: Cyclical food purchasing was observed broadly across different household characteristics and food categories, with notable differences by household economic means and food security status. Proposed SNAP policy changes designed to smooth food expenditures across the benefit month, such as increased frequency of benefit distribution, should include a focus on households with fewest resources.

Associations between shopper impulsivity and cyclical food purchasing: Results from a prospective trial of low-income households receiving monthly benefits.

Supplemental Nutrition Assistance Program (SNAP) benefits are rapidly depleted after distribution. This phenomenon, known as the benefit cycle, is associated with poor nutrition and health outcomes. Proposed interventions targeting the benefit cycle often focus on impulsive decision-making. However, it remains unclear whether shopper impulsivity is associated with food purchasing behavior. Using data from a prospective trial, we evaluate whether shopper impulsivity is associated with food purchasing behavior before and after households receive nutrition assistance. In this study, 249 low-income households in the Minneapolis-St. Paul, Minnesota, metropolitan area received monthly benefits for three months. Overall impulsivity and impulsivity subtraits of the primary shopper was assessed using the Barratt Impulsiveness Scale-11. Both total food expenditures and expenditures for two specific categories (fruits and vegetables, and foods high in added sugar) were evaluated. Generalized estimating equations were used to model household expenditures as a function of week since benefit distribution, impulsivity, and their interaction. Results showed that during the benefit period, food expenditures were cyclical and patterned by impulsivity. Shoppers with greater overall impulsivity spent $40.62 more in week 1 (p < 0.001). While more impulsive shoppers spent more on foods high in added sugar throughout the month (p < 0.05 for all weeks), no patterns were observed for fruits and vegetables. These findings suggest that greater impulsivity exacerbates cyclical food purchasing behavior. The impact of shopper impulsivity is especially notable for expenditures on foods high in added sugar. SNAP educational interventions to mitigate the benefit cycle may be strengthened by focusing on more impulsive shoppers and on strategies to reduce impulsive purchases of foods high in added sugar.

Importance of the Supplemental Nutrition Assistance Program in Rural America.

There is great interest in reshaping the Supplemental Nutrition Assistance Program (SNAP) so that it better supports family nutrition, and an array of program changes have been proposed.We note the importance of considering the unique needs of rural SNAP participants when considering and implementing these changes. We also describe the SNAP-related needs and challenges unique to rural SNAP participants, and through this lens we discuss changes to SNAP that have been proposed and special considerations related to each. The special considerations we identified include allowing canned, frozen, and dried fruits and vegetables as eligible items in financial incentive programs in rural areas; changing direct education programming to address transportation-related barriers many rural families face in attending in-person classes; and supporting rigorous research to evaluate the potential benefits and unintended consequences of proposed program changes for which scant high-quality evaluation data exist.Evaluation studies should include rural SNAP participants so that effects in this important population group are known.

Health Information Brokers in the General Population: An Analysis of the Health Information National Trends Survey 2013-2014.

BACKGROUND: Health information exchanged between friends or family members can influence decision making, both for routine health questions and for serious health issues. A health information broker is a person to whom friends and family turn for advice or information on health-related topics. Characteristics and online behaviors of health information brokers have not previously been studied in a national population. OBJECTIVE: The objective of this study was to examine sociodemographic characteristics, health information seeking behaviors, and other online behaviors among health information brokers. METHODS: Data from the Health Information National Trends Survey (2013-2014; n=3142) were used to compare brokers with nonbrokers. Modified Poisson regression was used to examine the relationship between broker status and sociodemographics and online information seeking. RESULTS: Over half (54.8%) of the respondents were consulted by family or friends for advice or information on health topics (ie, they acted as health information brokers). Brokers represented 54.1% of respondents earning <$20,000 yearly and 56.5% of respondents born outside the United States. Women were more likely to be brokers (PR 1.34, 95% CI 1.23-1.47) as were those with education past high school (PR 1.42, CI 1.22-1.65). People aged ≥75 were less likely to be brokers as compared to respondents aged 35-49 (PR 0.81, CI 0.67-0.99). Brokers used the Internet more frequently for a variety of online behaviors such as seeking health information, creating and sharing online content, and downloading health information onto a mobile device; and also reported greater confidence in obtaining health information online. CONCLUSIONS: More than 50% of adults who responded to this national survey, including those with low income and those born abroad, were providing health information or advice to friends and family. These individuals may prove to be effective targets for initiatives supporting patient engagement and disease management, and may also be well-positioned within their respective social networks to propagate health messages.

Effects of Inclusion of Food Purchase Restrictions and Incentives in a Food Benefit Program on Diet Quality and Food Purchasing: Results From a Randomized Trial.

BACKGROUND: There is interest in reshaping the Supplemental Nutrition Assistance Program (SNAP) to better support family nutrition. OBJECTIVE: The Grocery Assistance Program Study (GAPS) for Families evaluated the effects of prohibiting using program funds for the purchase of certain sugary foods on the nutritional quality of foods purchased and consumed by program participants. DESIGN: A randomized experimental trial was carried out with participants randomized to one of three food benefit conditions. Baseline and follow-up measures collected included interviewer-administered 24-hour dietary recalls, food purchase receipts, food security, height, and weight. PARTICIPANT/SETTING: Adult-child dyads in households eligible for SNAP but currently not enrolled were recruited from the Minneapolis/St Paul MN metropolitan area from May of 2018 through May of 2019. A total of 293 adult-child dyads received the intervention as allocated. Of these dyads, 233 adults completed follow-up measures and met criteria for inclusion in the analytic sample, resulting in an attrition rate of 20.5%. A total of 224 children completed follow-up measures and met criteria for inclusion in the analytic sample, resulting in an attrition rate of 23.5%. INTERVENTION: Participants were randomized to 1 of 3 conditions: restriction (not allowed to buy sugar-sweetened beverages [SSB], sweet baked goods, or candy with program funds); restriction paired with incentive (30% incentive for fruits and vegetables [FV] purchased with funds); and control (funds provided with no restrictions or incentives). Funds were provided on a 4-week cycle for 20 weeks via a study-provided debit card. MAIN OUTCOME MEASURES: The primary outcome was the Healthy Eating Index (HEI)-2015 total score. Additional outcomes included selected HEI-2015 component scores; energy intake; food security; body weight; and purchasing of SSB, sweet baked goods, candies, fruits, and vegetables. STATISTICAL ANALYSIS: Linear regression analyses were conducted with change in the outcome regressed on treatment condition for the primary outcome analyses. RESULTS: No differences were observed between conditions in change in the nutrition and food security measures examined. Purchases of SSB and sweet baked goods and candies significantly differed by experimental condition. Purchase of restricted foods was lower at follow-up in the restriction and restriction paired with incentive conditions compared with the control condition. For example, spending on SSB at follow-up was significantly lower in the restriction ($2.66/week) and restriction paired with incentive ($2.06/week) conditions in comparison with control condition ($4.44/week) (P < 0.0003 and P < 0.0001, respectively). CONCLUSIONS: This study failed to find evidence in support of prohibiting the purchase of sugary foods with food program funds as a strategy to improve program participant nutrition, even when paired with an FV incentive. Research carried out in the context of the SNAP program is needed for a more robust evidence base.

Use of the Emergency Food System among Food Insecure, Low-income Households in the United States 2015 to 2020.

The emergency food system (EFS) is a critical part of the United States' social safety net. Using 2015-2020 Current Population Survey Food Security Supplement data, we identified trends in EFS use among food insecure, low-income households by estimating the probability of EFS use adjusting for demographics using multivariable logistic regression. From 2015-2019, between 31.0% and 34.4% of households received emergency food, while 42.4% did in 2020. EFS use did not increase in 2020 compared to prior years for older adults and non-metropolitan households. Targeted outreach should be used to expand the reach of this resource to underserved and marginalized populations."

Food security among SNAP participants 2019 to 2021: a cross-sectional analysis of current population survey food security supplement data.

Surveillance data indicate that food security rates increased among Supplemental Nutrition Assistance Program (SNAP) participants during the COVID-19 pandemic (2020 and 2021) compared with pre-pandemic (2019), but this could have been due to increased participation from better resourced households. Our objective was to examine if demographic differences between SNAP-participating households in each year were responsible for the increased prevalence of food secure households. We calculated the observed 30-d food security prevalence among SNAP-participating households for each year. We used indirect standardisation to produce expected 2020 and 2021 prevalences with 2019 as the standard population using household size, income, age, sex, race, Hispanic ethnicity, presence of children, single parent household, metropolitan status and census region. We calculated standardised prevalence ratios (SPRs) to understand if the observed prevalence was higher than expected given any changes in the demographic profile compared to 2019. The Current Population Survey data were collected by the United States Census Bureau and Department of Agriculture. Our sample included 5,245 SNAP-participating households. The observed prevalence of food secure households increased by 3⋅6 percentage points comparing 2019 to 2020 (SPR = 1⋅06, 95 % confidence interval = 1⋅00, 1⋅11) and by 8⋅6 percentage comparing 2019 to 2021 (SPR = 1⋅13, 95 % confidence interval = 1⋅07, 1⋅18). The greater prevalence of food secure SNAP households during the pandemic did not appear to be attributable to socio-demographic differences compared to pre-pandemic. Despite hesitance among policymakers to expand or enhance social safety net programmes, permanently incorporating COVID-19-related policy interventions could lessen food insecurity in years to come.

Nutrient Composition of a Selection of Plant-Based Ground Beef Alternative Products Available in the United States.

BACKGROUND: Sales of plant-based foods intended as direct replacements for animal products have been growing in the United States. Little is known about the nutritional quality of these products. OBJECTIVE: Our aim was to evaluate the nutritional quality of a selection of plant-based ground beef alternative products available in the US marketplace and compare it with the nutrient content of ground beef. DESIGN: We conducted an analysis of the food and nutrient composition information available for plant-based ground beef alternative products in the 2020 version of the University of Minnesota Nutrition Coordinating Center Food and Nutrient Database. PARTICIPANT/SETTING: We analyzed a selection of 37 plant-based ground beef alternative products available in the United States in 2019. MAIN OUTCOMES MEASURES: Food product content of energy, macronutrients, fatty acids, vitamins, minerals and selected additional food components was measured. STATISTICAL ANALYSIS: The percent Daily Value (DV) per 3-ounce cooked portion of each product was determined for nutrients with a DV. The median, interquartile range (IQR), minimum, and maximum nutrient values were calculated for all products by classification as vegan and nonvegan. RESULTS: The median saturated fat content of the plant-based ground beef alternatives products as a %DV was 4% (IQR 2%). Vitamin and minerals for which median %DV values for plant-based ground beef alternative products were 10% or higher included folate (10%, IQR 10%), niacin (21%, IQR 7%), iron (10%, IQR 5%), phosphorous (10%, IQR 4%), sodium (18%, IQR 7%), manganese (20%, IQR 20%), and copper (24%, IQR 10%). The median dietary fiber content of the plant-based ground beef alternative products was 15% of the DV (IQR 6%). Most of the products contained less protein, zinc, and vitamin B12 than ground beef. CONCLUSIONS: The major brands of plant-based ground beef alternative products examined in this study have nutritional strengths as well as some shortcomings. Additional research to examine a broader set of plant-based meat alternative products, such as those designed as substitutes for chicken and pork, is warranted.

Within- and Between-Household Variation in Food Expenditures Among Low-Income Households Using a Novel Simple Annotated Receipt Method.

Background: Household food purchasing behavior has gained interest as an intervention to improve nutrition and nutrition-associated outcomes. However, evaluating food expenditures is challenging in epidemiological studies. Assessment methods that are both valid and feasible for use among diverse, low-income populations are needed. We therefore developed a novel simple annotated receipt method to assess household food purchasing. First, we describe and evaluate the extent to which the method captures food purchasing information. We then evaluate within- and between-household variation in weekly food purchasing to determine sample sizes and the number of weeks of data needed to measure household food purchasing with adequate precision. Methods: Four weeks of food purchase receipt data were collected from 260 low-income households in the Minneapolis-St. Paul metropolitan area. The proportion of receipt line items that could not be coded into one of 11 food categories (unidentified) was calculated, and a zero-inflated negative binomial regression was used to evaluate the association between unidentified receipt items and participant characteristics and store type. Within- and between-household coefficients of variation were calculated for total food expenditures and several food categories. Results: A low proportion of receipt line items (1.6%) could not be coded into a food category and the incidence of unidentified items did not appreciably vary by participant characteristics. Weekly expenditures on foods high in added sugar had higher within- and between-household coefficients of variation than weekly fruit and vegetable expenditures. To estimate mean weekly food expenditures within 20% of the group's usual ("true") expenditures, 72 households were required. Nine weeks of data were required to achieve an r = 0.90 between observed and usual weekly food expenditures. Conclusions: The simple annotated receipt method may be a feasible tool for use in assessing food expenditures of low-income, diverse populations. Within- and between-household coefficients of variation suggest that the number of weeks of data or group sizes required to precisely estimate usual household expenditures is higher for foods high in added sugar compared to fruits and vegetables.

Progress in national and regional guidelines development and deployment for the clinical prevention and control of CVD and diabetes in Africa.

Successful efforts to reduce cardiovascular disease in many countries have come as a result of both population based interventions and individually guided interventions. Guidelines serve two purposes directed at the promotion of the individually guided interventions. First, they serve as a method to summarize approved and successful life-style and medical interventions to reduce the burden of cardiovascular disease. Second, they guide health providers on how to identify those at high risk for cardiovascular disease and who might benefit from the available interventions. However, guidelines have been increasingly complex and at times contradictory from one body to another or they may not exist at all in certain countries. This paper will review the current status of guidelines for the region as well as for individual countries. Guidelines for the prevention of CVD as a whole will be evaluated as well as guidelines for individual risk factors such as hypertension, cholesterol, and diabetes. Finally, this paper will address the pitfalls of individual risk factor based guidelines as opposed to the absolute risk approach integrating multiple risk factors into one comprehensive set of guidelines.

Studies to reduce unnecessary medication use in frail older adults: a systematic review.

BACKGROUND: Overuse of unnecessary medications in frail older adults with limited life expectancy remains an understudied challenge. OBJECTIVE: To identify intervention studies that reduced use of unnecessary medications in frail older adults. A secondary goal was to identify and review studies focusing on patients approaching end of life. We examined criteria for identifying unnecessary medications, intervention processes for medication reduction, and intervention effectiveness. METHODS: A systematic review of English articles using MEDLINE, EMBASE, and International Pharmaceutical Abstracts from January 1966 to September 2012. Additional studies were identified by searching bibliographies. Search terms included prescription drugs, drug utilization, hospice or palliative care, and appropriate or inappropriate. A manual review of 971 identified abstracts for the inclusion criteria (study included an intervention to reduce chronic medication use; at least 5 participants; population included patients aged at least 65 years, hospice enrollment, or indication of frailty or risk of functional decline-including assisted living or nursing home residence, inpatient hospitalization) yielded 60 articles for full review by 3 investigators. After exclusion of review articles, interventions targeting acute medications, or studies exclusively in the intensive care unit, 36 articles were retained (including 13 identified by bibliography review). Articles were extracted for study design, study setting, intervention description, criteria for identifying unnecessary medication use, and intervention outcomes. RESULTS: The studies included 15 randomized controlled trials, 4 non-randomized trials, 6 pre-post studies, and 11 case series. Control groups were used in over half of the studies (n = 20). Study populations varied and included residents of nursing homes and assisted living facilities (n = 16), hospitalized patients (n = 14), hospice/palliative care patients (n = 3), home care patients (n = 2), and frail or disabled community-dwelling patients (n = 1). The majority of studies (n = 21) used implicit criteria to identify unnecessary medications (including drugs without indication, unnecessary duplication, and lack of effectiveness); only one study incorporated patient preference into prescribing criteria. Most (25) interventions were led by or involved pharmacists, 4 used academic detailing, 2 used audit and feedback reports targeting prescribers, and 5 involved physician-led medication reviews. Overall intervention effect sizes could not be determined due to heterogeneity of study designs, samples, and measures. CONCLUSIONS: Very little rigorous research has been conducted on reducing unnecessary medications in frail older adults or patients approaching end of life.
