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 w…

Recruitment of Low-wage Workers for a Time-sensitive Natural Experiment to Evaluate a Minimum Wage Policy: Challenges and Lessons Learned
Natural experiments are often used for answering research questions in which randomization is implausible. Effective recruitment strategies are well documented for observational cohort studies and clinical trials, unlike recruitment methods for time-sensitive natural experiments. In this time-sensitive study of the impact of a minimum wage policy, we aimed to recruit 900 low-wage workers in Minneapolis, Minnesota, and Raleigh, North Carolina. We …

How Well Do U.S. Hispanics Adhere to the Dietary Guidelines for Americans? Results from the Hispanic Community Health Study/Study of Latinos
Purpose: To examine alignment between 2010 Dietary Guidelines for Americans (DGA) and dietary choices of individuals in the Hispanic Community Health Study/Study of Latinos (HCHS/SOL) between 2008 and 2011. Methods: Data are from 15,633 adults 18–74 years from the population-based cohort in HCHS/SOL. The Healthy Eating Index (HEI) 2010 was used to measure diet quality. Means and standard errors (SEs) for the HEI total and each of the 12 component…
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 t…
Assessment of the accuracy of nutrient calculations of five popular nutrition tracking applications
Objective To assess the accuracy of nutrient intake calculations from leading nutrition tracking applications (apps). Design Nutrient intake estimates from thirty 24 h dietary recalls collected using Nutrition Data System for Research (NDSR) were compared with intake calculations from these recalls entered by the researcher into five free nutrition tracking apps. Apps were selected from the Apple App Store based on consumer popularity from the li…
Preliminary evaluation of the Healthy Savings Program: A novel health insurance-based wellness programme to encourage healthy food purchases
Objective To examine level of participation and satisfaction with the Healthy Savings Program (HSP), a programme that provides price discounts on healthier foods. Design For Study 1, a survey was distributed to a random sample of adults who were invited to participate in a version of the HSP that provided a discount for the purchase of fresh produce and discounts on other healthier foods. In Study 2, interviews were conducted with a convenience s…
Pricing of Staple Foods at Supermarkets versus Small Food Stores
Prices affect food purchase decisions, particularly in lower-income communities, where access to a range of food retailers (including supermarkets) is limited. The aim of this study was to examine differences in staple food pricing between small urban food stores and the closest supermarkets, as well as whether pricing differentials varied based on proximity between small stores and larger retailers. In 2014, prices were measured for 15 staple fo…
Impact of explained v . unexplained front-of-package nutrition labels on parent and child food choices: A randomized trial
Neither MTL nor FuF FOP labels led to food choices with significantly lower saturated fat, sodium or sugar. In-aisle signs explaining the FOP labels were somewhat helpful to consumers in making more healthful dietary decisions. New FOP labelling programmes could benefit from campaigns to increase consumer awareness and understanding of the labels
Successful customer intercept interview recruitment outside small and midsize urban food retailers
Customer intercept interviews can be successfully used to recruit diverse samples of customers at small and midsize food retailers. Future community-based studies using customer intercept interviews should collect data sufficient to report response rates and consider potential differences between the racial/ethnic composition of the recruited sample and the target population
Estimating bisphenol A exposure levels using a questionnaire targeting known sources of exposure
Objective To develop a BPA Exposure Assessment Module (BEAM) for use in large observational studies and to evaluate the ability of the BEAM to estimate bisphenol A (BPA) exposure levels. Design The BEAM was designed by modifying an FFQ with questions targeting known sources of BPA exposure. Frequency of intake of known dietary sources of BPA was assessed using the BEAM and three 24 h food records as a reference diet measurement tool. Urinary BPA …
The potential impact of Supplemental Nutrition Assistance Program (SNAP) restrictions on expenditures: A systematic review
Objective To systematically review the potential impact of reducing the set of Supplemental Nutrition Assistance Program (SNAP)-eligible foods (e.g. not allowing purchase of sugar-sweetened beverages with SNAP benefits) on expenditures for restricted foods. Design The impact on food expenditures of a $US 1 reduction in available SNAP benefits can be used to estimate the impact of restrictions on SNAP-eligible foods. An electronic search of EconPa…
