People with overweight and obesity tend to both underreport dietary energy intake and experience weight stigma. This exploratory pilot study aimed to determine the relationship between weight bias and weight stigma and energy intake reporting accuracy. Thirty-nine weight-stable adults with BMI ≥ 25 completed three 24 h dietary recalls; indirect calorimetry to measure resting metabolic rate; a survey measuring weight stigma, psychosocial constructs, and physical activity; and a semi-structured qualitative interview. Multiple linear regression was used to determine if weight bias internalization, weight bias toward others, and experiences of weight stigma were predictive of the accuracy of energy reporting. A thematic analysis was conducted for the qualitative interviews. Weight stigma was reported by 64.1% of the sample. Weight stigma constructs did not predict the accuracy of energy intake reporting. People with obesity underreported by a mean of 477 kcals (p = 0.02). People classified as overweight overreported by a mean of 144 kcals, but this was not significant (p = 0.18). Participants reported a desire to report accurate data despite concerns about reporting socially undesirable foods. Future research should quantify the impact of weight stigma on energy reporting in 24 h recalls using a larger, more diverse sample size and objective measures like doubly labeled water for validation.

Adequate water intake is essential for human health. Sugary beverage taxes are a best buy policy to reduce obesity and diet-related non-communicable diseases. Food-based dietary guidelines (FBDGs) promote healthy dietary patterns. The study purpose was to evaluate national FBDGs for countries with sugary beverage tax legislation (2000–2023) to promote water and discourage sugary beverage consumption. We developed a coding framework to conduct a content analysis of FBDG documents, and used six indicators to identify messages and images to assign healthy hydration recommendation (HHR) scores from 0–12 to compare FBDGs across countries and six regions. Results showed 93 countries with sugary beverage tax legislation of which 58 countries (62%) had published FBDGs (1998–2023). Of 58 FBDGs reviewed, 48 (83%) had complementary recommendations that encouraged water and discouraged sugary beverages. Of 93 countries, 13 (14%) had the highest HHR scores (11–12); 22, (24%) had high HHR scores (9–10); 20 (21%) had medium HHR scores (4–8); 3 (3%) had low HHR scores (0–3); and 35 (38%) countries had no FBDGs. To reduce health risks for populations, governments must ensure policy coherence to optimize sugary beverage tax impacts by developing FBDGs that encourage water and discourage sugary beverages complementary to national policies.

The COVID-19 pandemic has affected the food system, increasing barriers to food access and exac­erbating food insecurity across the U.S. The Vir­ginia state government initiated a stay-at-home order to help reduce the spread of COVID-19. Prior to the pandemic, the Virginia Fresh Match (VFM) Nutrition Incentive Network partnered with food retail outlets to provide Supplemental Nutrition Assistance Program (SNAP) participants point-of-purchase incentives (e.g., Double Up Food Bucks, SNAP Match), which function as matching discounts on fresh fruits and vegetables (F/V). These can enable participants to increase their purchasing power and potentially reduce food insecurity. In response to COVID-19, VFM removed the limit on incentive discounts (previ­ously $10[1]) to further incentivize the purchase of fresh F/V by SNAP participants. This study sought to characterize the purchasing patterns of SNAP participants at a food co-operative (co-op) partnered with VFM before and during the Virginia stay-at-home order. A total of 654 transactions at the co-op were included. Independent t-tests were utilized to determine differences before and during the order. The results indicated a significant in­crease in the mean incentive discount received dur­ing the order (pre-shutdown=$3.95, inter-shut­down=$5.01, p=0.035); however, simultaneously there was a decrease in the mean number of fresh F/V purchased (pre-shutdown=3.08, inter-shut­down=2.39, p=0.015). Although F/V purchases decreased, the presence of unlimited point-of-pur­chase incentives at the food co-op may have helped prevent a greater decline in fresh F/V pur­chases and helped increase access to fresh F/V in this population during the onset of the COVID-19 pandemic.

The purpose of this communication is to describe the preliminary evaluation of the Virginia Fresh Match (VFM) financial incentive program for fresh fruits and vegetables for Virginia Supplemental Nutrition Assistance Program shoppers and to determine if there were differences in incentive outcomes by race. In this cross-sectional study, a questionnaire was administered to shoppers using Virginia Fresh Match incentives at participating farmers markets and community-based food retail outlets. Repeated measures ANOVAs were used to detect differences in fruit and vegetable consumption between demographic groups over time. Chi-square tests were used to determine if there were associations between race and perceived impact of VFM incentives on making food last and the attribution of VFM incentives to changes in fruit and vegetable consumption frequency. Frequency of fruit and vegetable intake was significantly higher during VFM incentive use, with a difference of 1.17 ± 0.07 and 1.07 ± 0.07 on a Likert scale measure, respectively (p ≤ 0.001). There were racial differences in assertions that VFM incentives helped food to last. VFM incentives were effective at increasing fruit and vegetable consumption, but racial differences should be considered in the administration of VFM to avoid reinforcing systems or approaches that may contribute to disparities in food access and food security.
