Observational Study
BACKGROUND
Whole-grain (WG) foods are defined by the Dietary Guidelines for Americans (DGA), FDA, AHA, American Association of Cereal Chemists International (AACCI), and Whole Grains Council (WGC) in different ways with diverse focuses on grain components only, whole foods, or nutrient contents.
OBJECTIVES
We aimed to compare estimated WG food intake among US adults using different definitions.
METHODS
For each definition, we estimated the mean intake and trends of WG food consumption using survey-weighted 24-h dietary recalls from nationally representative samples of 39,755 US adults aged 20+ y from 8 cycles (2003-2018) of the NHANES. This is an observational study that used deidentified and publicly available datasets.
RESULTS
The estimated mean consumption of WG foods (ounces equivalents/2000 kcal/d, oz. eq./d) varied by definition. In 2017-2018, the AHA (mean [SEM]: 1.05 [0.07] oz. eq./d) and WGC (0.95 [0.07]) definitions yielded the highest amounts, followed by the DGA (0.81 [0.06]), AACCI (0.73 [0.05]), and FDA (0.53 [0.04]). Using all definitions except for WGC, US adults increased WG food intake from 2003-2004 to 2017-2018 with the largest increase (61.5%) using the AHA (from 0.65 to 1.05 oz. eq./d), followed by DGA (0.50 to 0.81) and AACCI (0.51 to 0.73) definitions. For each definition, the main sources of WG foods consumed by US adults were ready-to-eat cereals, cooked grains and cereals, and breads (including rolls and tortillas). For all definitions except the AHA, non-Hispanic White adults and individuals with college degrees or above consumed higher levels of WG foods than non-Hispanic Blacks and those with lower levels of education.
CONCLUSIONS
Different definitions affect the determination of WG foods, estimated intakes, and associated trends in WG food consumption among US adults. These findings call for a standardized definition of WG foods to guide consumers, industry, and policymakers in promoting WG intake in the US.Clinical Trial Registration: Not Applicable.

Randomized Controlled Trial
BACKGROUND
The demands of typical daily activities require a constant level of alertness and attention. Multi-ingredient, caffeine-containing supplements have been shown to improve measures of cognitive performance. As many of these supplements become readily available, efficacy of each should be evaluated. Therefore, the purpose of this study is to examine the effects of the 4D dietary supplement on cognition, reaction time, and reactive agility.
METHODS
Seventeen healthy males (n = 8) and females (n = 9) between the ages of 18-40 years old (22.8 ± 2.9 years; 167.3 ± 9.6 cm; 65.4 ± 10.9 kg) participated in this double-blind, randomized crossover study. Participants completed three baseline reaction time assessments on the Dynavision and one baseline multiple object tracking assessment on the Neurotracker. Participants then consumed the oral multi-ingredient supplement containing 150 mg of caffeine or non-caffeinated placebo, mixed with 24 ounces of water, and rested for 45 minutes. Following the rest period, participants completed an additional three reaction time assessments and one multiple object tracking (MOT) assessment, as well as 6-12 trials of the Y-reactive agility test. Repeated measures ANOVAs were used to evaluate YRA performance and change values for Dynavision RT, Dynavision score, and MOT speed with either 4D dietary supplement or placebo.
RESULTS
A significant time × supplement interaction was shown for MOT speed (p = .040, .543). Change scores in MOT speed were significantly different from zero following 4D (mean: 0.224 au; 95% confidence interval: 0.050 to 0.398 au) but not placebo supplementation (mean: -0.046 au; 95% confidence interval: -0.220 to 0.127 au). No time × supplement interaction was shown for Dynavision RT (p = .056, = -.499) or Dynavision score (p = .093, = .434). No differences were shown for YRA scores following supplementation for the right side (p = .241, 95) or left side (p = .378, 20).
CONCLUSION
The 4D dietary supplement appears to improve measures of cognition, specifically attention/spatial awareness, but not reaction time or reactive agility. Future research should examine the effects of this supplement with a larger, less heterogeneous sample and/or in conjunction with an exercise intervention.

BACKGROUND
The United States Centers for Disease Control and Prevention recommended a third dose or booster of the Pfizer-BioNTech Comirnaty (BNT162b2) COVID-19 mRNA vaccine in September 2021 for high-risk individuals. Pregnant and high-risk lactating women were encouraged to receive the booster to obtain potential prolonged protection for themselves and their infants.
RESEARCH AIM
To investigate the ability of the booster vaccine to increase IgA and IgG antibodies specific to the receptor-binding domain of the SARS-CoV-2 spike protein in human milk compared to levels pre-booster.
METHODS
This was a prospective one-group study with a pretest-posttest design. Six of 12 participants were recruited prospectively. Participants were instructed to collect ≥ 2 ounces of milk in the morning at 30 days and 1-day pre-booster, and 7, 14, 21, 30, 45, and 60 days post-booster. Levels of IgA and IgG antibodies specific to the receptor-binding domain of the SARS-CoV-2 spike protein were quantified in human milk via an ELISA assay.
RESULTS
We found a significant increase in anti-receptor-binding domain-specific IgA and IgG antibodies in human milk 1-2 weeks after the Pfizer-BioNTech booster and at the study endpoint (45- and 60-days post-booster).
CONCLUSIONS
This suggests that the booster vaccination enhances SARS-CoV-2 specific immunity in human milk, which may be protective for infants.

BACKGROUND
Cardinal and non-cardinal dysmorphic features are associated with prenatal alcohol exposure (PAE); however, their association with neurodevelopment is less clear. The objective of this study was to determine whether alcohol-related dysmorphic features predict neurodevelopmental delay in infants and toddlers.
METHODS
We analyzed a prospective pregnancy cohort in western Ukraine enrolled between 2008 and 2014. A dysmorphology examination comprising body size and three cardinal and 14 non-cardinal dysmorphic features was performed at approximately 6 to 12 months of age. PAE was self-reported and operationalized as absolute ounces of alcohol per day around the time of conception. Neurodevelopment was assessed at 6 to 12 months with the Bayley Scales of Infant Development-II (BSID-II), and at 3.5 to 4.5 years of age with the Differential Ability Scales-II, the Child Behavior Checklist, and multiple measures that were used to create an executive functioning factor score. We performed logistic regression to predict children's neurodevelopment from dysmorphic features, growth measures, sex, and PAE.
RESULTS
From an analytic sample of 582 unique children, 566 had BSID-II scores in infancy, and 289 completed the preschool battery. Models with all cardinal and non-cardinal dysmorphic features, growth measures, sex, and PAE performed better than models with subsets of those inputs. In general, models had poor performance classifying delays in infancy (area under the curve (AUC) <0.7) and acceptable performance on preschool-aged outcomes (AUC ~0.75). When the sample was limited to children with moderate-to-high PAE, predictive ability improved on preschool-aged outcomes (AUC 0.76 to 0.89). Sensitivity was relatively low for all models (12% to 63%), although other metrics of performance were higher.
CONCLUSION
Predictive analysis based on dysmorphic features and measures of growth performed modestly in this sample. As these features are more reliably measured than neurodevelopment at an earlier age, the inclusion of dysmorphic features and measures of growth in predictive models should be further explored and validated in different settings and populations.

During the COVID-19 epidemic, personal safety has received increasing attention, leading to behavioral changes. Mobile-wallet (m-wallet) makes it easier for people to keep social distance, which helps stop the spread of the COVID-19 virus. Evolving Internet technology has brought about changes in consumer lifestyle. The current situation of COVID-19 has created a business environment to shift from traditional ways and adopt e-commerce solutions worldwide. Grounded in technology acceptance model (TAM) theory, this study's objective is two-fold: First, this study intends to examine perceived susceptibility to COVID-19, perceived severity of COVID-19, insecurity and discomfort as the predictors of perceived usefulness (PU) and perceived ease of use (PEOU). Second, the current research intends to test the moderating effect of electronic words-of-mouth (eWOM) on the relationship between attitude and usage intention. Using survey methods, 226 usable responses were collected through a mall intercept survey in Pakistan. Data were analyzed using partial least square (PLS). The results revealed that PEOU and PU positively influence attitude toward M-wallet. This study has found that attitude positively influences the usage intention in adopting M-wallet. The results also support the moderating role of eWOM. These findings contribute to the marketing literature in several ways, particularly in Pakistan. This is the first study to use eWOM as a moderating variable in the TAM theory. In addition, this study adds to the current body of knowledge by considering eWOM as a multi-dimensional construct novel in m-wallet literature.

BMJ Open Oct 2022This study estimates the effect of chronic disease diagnoses (CDDs) on elderly Chinese individuals' alcohol consumption behaviour.
OBJECTIVES
This study estimates the effect of chronic disease diagnoses (CDDs) on elderly Chinese individuals' alcohol consumption behaviour.
SUBJECTS AND PARTICIPANTS
Our analysis was applied to a publicly available dataset that covers 5724 individuals aged 50 or above and spans 15 years (2000-2015: six waves) from the China Health and Nutrition Survey.
DESIGN
The outcome variables are elderly individuals' weekly consumption of alcoholic beverages: beer, red wine, Chinese spirits and total alcohol intake. The explanatory variable of primary interest is the number of chronic diseases diagnosed (including hypertension, diabetes, stroke and myocardial infarction). Other covariates concern sample individuals' sociodemographic and health-related characteristics. A Chamberlain-Mundlak correlated random-effect Tobit model is adopted to simultaneously account for the clustering of 'zeros' in the outcome variable and endogeneity issues such as omitted variables and reverse causality.
RESULTS
Our estimation suggests that, on average, an additional chronic disease diagnosed by medical doctors reduced an elderly Chinese individual's weekly consumption of beer, red wine and Chinese spirits, respectively, by 1.49 (95% CI -2.85 to -0.13), 0.93 (95% CI -1.63 to -0.23) and 0.89 (95% CI -1.23 to -0.54) ounces. These effects translate into a reduction of 0.95 (95% CI -1.29 to -0.60) ounces in total weekly alcohol consumption and a reduction of 24% (95% CI -0.35 to -0.14) in the incidence of excessive drinking. Further explorations suggest that elderly Chinese individuals' alcohol consumption is most responsive to diabetes and stroke diagnoses, but the effects vary across different beverages. Moreover, males, rural residents, smokers and those living with non-drinkers respond to CDDs more strongly than their respective counterparts.
CONCLUSION
While CDDs reduced alcohol consumption among elderly Chinese individuals, they failed to stop all heavy drinkers from excessive drinking. Relevant policies and measures are thus needed to urge heavy drinking patients to quit excessive drinking.

INTRODUCTION
Simulation modeling methods are an increasingly common tool for projecting the potential health effects of policies to decrease sugar-sweetened beverage (SSB) intake. However, it remains unknown which SSB policies are understudied and how simulation modeling methods could be improved. To inform next steps, we conducted a scoping review to characterize the (1) policies considered and (2) major characteristics of SSB simulation models.
METHODS
We systematically searched 7 electronic databases in 2020, updated in 2021. Two investigators independently screened articles to identify peer-reviewed research using simulation modeling to project the impact of SSB policies on health outcomes. One investigator extracted information about policies considered and key characteristics of models from the full text of included articles. Data were analyzed in 2021-22.
RESULTS
Sixty-one articles were included. Of these, 50 simulated at least one tax policy, most often an ad valorem tax (e.g., 20% tax, n = 25) or volumetric tax (e.g., 1 cent-per-fluid-ounce tax, n = 23). Non-tax policies examined included bans on SSB purchases (n = 5), mandatory reformulation (n = 3), warning labels (n = 2), and portion size policies (n = 2). Policies were typically modeled in populations accounting for age and gender or sex attributes. Most studies focused on weight-related outcomes (n = 54), used cohort, lifetable, or microsimulation modeling methods (n = 34), conducted sensitivity or uncertainty analyses (n = 56), and included supplementary materials (n = 54). Few studies included stakeholders at any point in their process (n = 9) or provided replication code/data (n = 8).
DISCUSSION
Most simulation modeling of SSB policies has focused on tax policies and has been limited in its exploration of heterogenous impacts across population groups. Future research would benefit from refined policy and implementation scenario specifications, thorough assessments of the equity impacts of policies using established methods, and standardized reporting to improve transparency and consistency.

BACKGROUND
Flavored tobacco products are highly appealing to youth. The Federal government lacks a comprehensive flavored tobacco products policy and states have adopted different approaches restricting these products. This study analyzes the impact of Massachusetts' comprehensive prohibition and New Jersey's partial restriction on the sale of flavored tobacco products.
METHODS
NielsenIQ Retail Scanner data were used to construct four log per capita dependent variables: e-liquid milliliters, cigarette packs, cigars, and smokeless tobacco ounces for products flavored as fruit, menthol, mint, tobacco and other. All models used difference-in-differences regressions, with Virginia and Pennsylvania serving as controls. The models controlled for state level product prices, population percentages by race/ethnicity, proportion male, median household income, unemployment rate, minimum legal sales age, tobacco 21 policies, and cumulative cases and deaths of COVID-19; the models accounted for time-specific factors by using 4-week period fixed-effects.
RESULTS
There was a significant decrease in sales across all flavored tobacco products in Massachusetts, including fruit [-99.83%, p < 0.01], menthol [-98.33%, p < 0.01], and all other flavored [-99.28%, p < 0.01] e-cigarettes. The cigar group "all other-flavors" [-99.92%, p < 0.01] and menthol flavored cigarettes [-95.36%, p < 0.01] also significantly decreased. In New Jersey, there was a significant decrease in per capita sales of menthol-flavored e-cigarettes [-83.80%, p < 0.05] and cigar group "all other-flavors" experienced a significant increase in per capita sales [380.66%, p < 0.01].
CONCLUSIONS
This study contributes to the growing body of evidence demonstrating the impact of sales prohibitions on reducing sales of flavored tobacco products. Statewide comprehensive approaches appear more effective than partial restrictions and should be prioritized.
IMPLICATIONS
Results from this study support emerging research that demonstrates the promising effects of comprehensive flavoring sales prohibitions. This study can be used to inform future flavored tobacco product policy solutions developed by advocates and policy makers to curb overall tobacco initiation and use by youth and adults.

An ounce of prevention is worth a pound of cure-the arts as a vehicle for knowledge translation and exchange (KTE) in public health during a pandemic: a realist-informed developmental evaluation research protocol.
INTRODUCTION
The COVID-19 crisis has led to the adoption of strict and coercive preventive measures. The implementation of these measures has generated negative impacts for many communities. The situation is especially worrisome for Indigenous communities in Peru. Therefore, it is necessary to recognise the contribution of the experiential knowledge of Indigenous communities and to implement innovative approaches. The use of art can be a promising avenue for working in partnership with Indigenous communities.The goal of this research is to (1) develop an intervention promoting barrier measures and vaccination to limit the transmission of COVID-19 among Indigenous communities using an arts-based and community-based knowledge translation and exchange (ACKTE) model; and (2) understand the contextual elements and mechanisms associated with the process of developing a preventive intervention using the ACKTE model.
METHODOLOGY AND ANALYSIS
This research will take place in Indigenous communities in Peru and will be based on a developmental evaluation guided by the principles of realist evaluation. Members of two Indigenous communities, local authorities, health professionals and artists will participate in the intervention development process as well as in the developmental evaluation. For data collection, we will conduct modified talking circles and semistructured individual interviews with stakeholders as well as an analysis of documents and artistic works produced.
ETHICS AND DISSEMINATION OF RESULTS
This research received the approval of the 's research ethics board. In addition to scientific articles, the results of this research will be disseminated through videos and during an artistic performance.

Some consider potatoes to be unhealthy vegetables that may contribute to adverse cardiometabolic health outcomes. We evaluated the association between potato consumption (including fried and non-fried types) and three key cardiometabolic outcomes among middle-aged and older adults in the Framingham Offspring Study. We included 2523 subjects ≥30 years of age with available dietary data from 3-d food records. Cox-proportional hazards models were used to estimate hazard ratios (HRs) and 95 % confidence intervals (CIs) for hypertension, type 2 diabetes or impaired fasting glucose (T2DM/IFG), and elevated triglycerides, adjusting for anthropometric, demographic and lifestyle factors. In the present study, 36 % of potatoes consumed were baked, 28 % fried, 14 % mashed, 9 % boiled and the rest cooked in other ways. Overall, higher total potato intake (≥4 . <1 cup-equivalents/week) was not associated with risks of T2DM/IFG (HR 0⋅97, 95 % CI 0⋅81, 1⋅15), hypertension (HR 0⋅95; 95 % CI 0⋅80, 1⋅12) or elevated triglycerides (HR 0⋅99, 95 % CI 0⋅86, 1⋅13). Stratified analyses were used to evaluate effect modification by physical activity levels and red meat consumption, and in those analyses, there were no adverse effects of potato intake. However, when combined with higher levels of physical activity, greater consumption of fried potatoes was associated with a 24 % lower risk (95 % CI 0⋅60, 0⋅96) of T2DM/IFG, and in combination with lower red meat consumption, higher fried potato intake was associated with a 26 % lower risk (95 % CI 0⋅56, 0⋅99) of elevated triglycerides. In this prospective cohort, there was no adverse association between fried or non-fried potato consumption and risks of T2DM/IFG, hypertension or elevated triglycerides.
