Proportional Contribution of the Women, Infant and Children's Special Supplemental Nutrition Program on Pregnant Women's Diet Quality

Objective: The purpose of this study was to identify the proportional contribution of the special Women’s Infant and Children Food Package V for pregnant women (WIC) supplementation on pregnant women’s diet quality. Methods: Image-based diet data collection using FoodFoto™ from 63 primigravid women with singleton pregnancies in Baltimore, Maryland receiving the special WIC Food Package V for pregnant women was converted to Healthy Eating Index - 2015 (HEI-2015) total and component diet quality scores. Descriptive statistics were used to describe the total and component HEI diet quality scores. Independent t-tests and linear regression models were used to assess the contributions that the percent of WIC food in the diet and sociodemographic and health characteristics had on the components and the overall HEI score. Results: The data showed a 1% rise in WIC approved foods in the diet was associated with a significant increase in the on the HEI-2015 score (b=0.77, t=6.35, p<0.001). Higher diet quality scores were accounted for by increased consumption of four HEI components representing healthy foods and significantly lower sodium intake. Furthermore, the healthy food component scores and fatty acids ratio were at or above the 50th percentile. Conclusion: Small increases in consumption of WIC approved foods significantly improved diet quality among pregnant women in the program.

The ABCDs of nutritional assessment in infectious diseases research.

Malnutrition is the most common acquired cause of immunodeficiency worldwide. Nutritional deficiencies can blunt both the innate and adaptive immune response to pathogens. Furthermore, malnutrition is both a cause and consequence of infectious diseases. The bidirectional relationship between infectious diseases and undernutrition, as well as the inflammatory milieu of infectious diseases, can complicate nutritional assessment. This article aims to provide clinicians and researchers with an overview of commonly used tools to assess nutritional status, with a particular emphasis on their use in the context of infectious diseases. This includes anthropometric, biochemical, clinical/physical, and dietary assessments to screen and evaluate undernutrition, diet quality, and food insecurity effectively.

Utilization of Microencapsulated Polyphenols to Enhance the Bioactive Compound Content in Whole Grain Bread: Recipe Optimization

In today’s health-conscious society, there is an increasing consumer demand for functional foods that not only satisfy nutritional needs but also promote overall well-being. The aim of this study was to develop a bread formulation enriched with microencapsulated polyphenols, oat β-glucan concentrate, and sour fermented beetroot juice to enhance its nutritional profile and health benefits. To protect sensitive polyphenols from thermal degradation during baking, the microencapsulation technique was employed to maintain their bioactivity. The influence of these ingredients on the physio-chemical parameters of bread (dough viscosity, hardness, porosity, bioactive ingredients content, color, and volatile compounds profiles), as well as sensory acceptability, was evaluated. Using response surface methodology, the formulation was optimized to achieve a product with high polyphenol and β-glucan content. The optimized formulation included a content of 4.60% sour fermented beetroot juice, 6.29% β-glucan concentrate, and 2.77% microencapsulated polyphenols. The final bread demonstrated significant antioxidant activity and high consumer acceptability, indicating its potential as a functional alternative to traditional bread. This innovative approach addresses the demand for healthier food options and emphasizes the role of functional ingredients in improving dietary quality and promoting health benefits.

Trends in Toddler Diet Quality in the United States: 1999 to 2018.

Diet quality has improved over time for US adults and youth aged ≥2 years. Trends over time and disparities in the diet quality of toddlers 12 through 23 months old have not been documented. Our objective was to investigate the direction and magnitude of toddler diet quality trends from 1999 to 2018 overall and by household socioeconomic status. This serial cross-sectional analysis of National Health and Nutrition Examination Survey (NHANES) data was performed with 2541 toddlers from 10 NHANES cycles from 1999 to 2018. Dietary intake was measured by NHANES study staff using proxy-reported 24-hour recalls. Healthy Eating Index-Toddlers-2020 total scores (0-100 points, higher scores indicate healthier diets) and component scores were calculated from the 24-hour dietary recalls using the population ratio method. Multivariable linear regression was used to evaluate the association between time in years (measured as the midpoint of each NHANES cycle) and diet quality. Toddler diet quality improved significantly from 1999 to 2018 (P < .001), from 63.7 points on average in 1999-2000 to 67.7 points in 2017-2018. A significant positive linear trend in total diet quality was observed for all socioeconomic status groups (P < .05). Several dietary component scores improved, as follows: Whole Fruits (P < .001), Whole Grains (P = .016), Fatty Acids (P = .002), Refined Grains (P = .009), and Added Sugars (P < .001). Scores did not significantly change for Total Fruit, Total Vegetables, Greens and Beans, Dairy, Total Protein Foods, Seafood and Plant Proteins, Sodium, or Saturated Fats. From 1999 to 2018, toddler diet quality improved significantly, but mean scores still fell short of dietary guidance.

Impact of debranning on the nutritional, cooking, microstructural characteristics of five Indian small millets

BackgroundMillets are underutilized grains rich in nutrients. This study aimed to investigate the impact of debranning on the nutritional, cooking, and microstructural properties of five Indian millets namely foxtail, little, kodo, barnyard, and proso millet.MethodsThe proximate composition, mineral content, cooking properties (cooking time, solid loss, water uptake, alkali score), Fourier Transform Infra Red (FTIR) spectra, X ray Diffraction (XRD) and microstructural characteristics (Scanning Electron Microscopy) of dehusked and debranned millet samples were examined and analysed.ResultsDebranning resulted in decrease in protein (except for little and barnyard millets), dietary fibre, fat, mineral and phytate content in all the millets while enhanced available carbohydrates and amylose content. The cooking times for dehusked millets were significantly higher while, the solid loss and water uptake during cooking of debranned millets were higher. On debranning, Fourier Transform Infra Red (FTIR) spectra showed changes in the pattern with increase in the intensity of amide II (1363 to 1367 cm−1) and amide III (1215 to 1231 cm−1) bands in the debranned foxtail, little, and kodo millets. The X-ray diffractogram (XRD) showed decrease in relative crystallinity on debranning. Scanning Electron Microscopic (SEM) examination revealed that debranning resulted in the loss of seed coat, aleurone layer and partial loss of germ in the millets.ConclusionDehusked millets are nutritious and should be promoted in Indian diets to improve diet quality, debranned millets are nutritionally inferior, can increase the glycemic load of Indian diets.

Associations of nutrition education with diet quality indexes and chronotype: a cross-sectional study

ABSTRACT This study examined the impact of nutrition education on chronotype, sleep quality, and dietary quality among university students. Participants included 317 students with nutrition education and 280 without. Data were collected through questionnaires assessing demographic characteristics, chronotype (using the Morning-Evening Questionnaire), sleep quality (via the Pittsburgh Sleep Quality Index), and dietary habits. Anthropometric measurements and 24-hour food recalls were also recorded. Dietary quality was evaluated using the Healthy Eating Index (HEI)-2020, while dietary fat and carbohydrate quality were assessed with the Fat Quality Index (FQI) and Carbohydrate Quality Index (CQI), respectively. Results indicated that students who received nutrition education had significantly lower body weight, height, and waist circumference compared to those without. Of the students, 8.9% had a morning, 7% had an evening and the rest had an intermediate chronotype. HEI-2020, CQI, and FQI scores were significantly higher in the nutrition education group. Although no significant relationship was found between nutrition education and chronotype, improved dietary and sleep quality were observed in the group with education. This suggested that enhancing nutritional knowledge can positively impact health by improving dietary quality and sleep.

Indulging in Tempting Yet Unhealthy Delights: Exploring the Moderating Influence of Gender and Motivation for Healthy and Sustainable Eating

Individuals frequently encounter alluring food temptations that can disrupt their efforts to follow a healthy diet. These temptations may trigger pleasurable thoughts and sensations, potentially leading to unhealthy eating habits and obesity, which misalign with the goals of sustainable food systems to promote overall well-being. However, there is limited knowledge regarding how individual differences such as gender and motivation for healthy eating might impact individuals’ responses to unhealthy food temptations. In an experimental investigation, 245 participants were exposed to a tasty but low-nutrient food product (potato crisps). The results provide several new insights: (a) when individuals’ motivation for healthy eating is low, pleasurable experiences have a positive impact on perceived dietary quality; (b) pleasurable feelings also directly reduce willingness to consume potato crisps; (c) gender influences the relationship between pleasure-feeling and willingness to eat, with a negative relationship for women and a non-significant relationship for men; and (d) among women, there is a positive relationship between arousal and willingness to eat, while this relationship is non-significant for men. This study adds to the body of knowledge already available on food temptations, nutrition, and sustainable eating.

Diet quality is positively associated with nature Relatedness in a U.S. Population: A pilot study

BackgroundSustainable dietary practices can help reduce greenhouse gas emissions and promote planetary health. The importance of investigating how to promote sustainable dietary practices is therefore crucial. Nature Relatedness measures an individual’s connection to nature and can predict environmental concern and stewardship. While emerging research has suggested those with a higher degree of Nature Relatedness report the intention to follow more sustainable dietary practices, the relationship between actual dietary intake and Nature Relatedness has yet to be fully explored. Therefore, the purpose of this pilot study was to assess the relationship between diet quality and Nature Relatedness. MethodsIn this cross-sectional study, participants across the United States completed the online survey from September to November 2023. Diet History Questionnaire II and Nature Relatedness scale were completed by the participants. Diet quality was assessed using the Healthy Eating Index (HEI)-2020 total and component scores. Nature Relatedness total and subscale scores were computed. Pearson and Spearman Rho correlation coefficients assessed associations between HEI-2020 and Nature Relatedness. Simple linear regression models examined the relationships between HEI-2020 total and component scores and Nature Relatedness (controlling for age, gender, race, and education). ResultsThree hundred adults completed the study. HEI-2020 total score was positively associated with Nature Relatedness (p < 0.001). Total fruit, total vegetable, green and beans, and refined grains component scores were positively associated with Nature Relatedness (p < 0.001). Nature Relatedness significantly predicted diet quality and total fruit, total vegetable, greens and beans, and moderation of refined grains consumption. ConclusionsThere are positive and significant relationships between diet quality, components of dietary intake that may promote planetary health, and Nature Relatedness. Our findings may be used to inform future research and nutrition intervention programs promoting personal and planetary health through nature-based interventions.

Adaptation of the Diet Quality Questionnaire as a global public good for use in 140 countries

BackgroundFood group consumption data is useful for measuring and monitoring diet quality. To collect valid data across contexts, consistent and rigorous adaptation of survey questions is needed. ObjectivesThe objective of this research is to adapt food group consumption survey questions for 140 countries, by identifying the most common (sentinel) food items in each food group using a structured, participatory process and global standards for classification. MethodsSurvey questions were adapted for 29 food groups of the Diet Quality Questionnaire (DQQ) and for additional questions for infant and young child feeding (IYCF) indicators. For each country, adaptation comprised: (1) review of existing questionnaires, dietary intake data, and other information to draft food lists; (2) key informant (KI) interviews with 5-12 experts to identify and prioritize sentinel items including terminology; (3) comparison of items across countries within the same region to identify discrepancies, and follow-up with KIs to resolve them. Results1,016 KIs contributed to the adapted DQQs for 140 countries and IYCF DQQs for 96 countries, amounting to approximately 9,550 hours of collective effort (68 person-hours/country on average) from 2020-2024. The process revealed numerous challenges and decisions to ensure consistent classification of items and valid question formulation. ConclusionCountry-specific questions adhering to global standards, and adapted through cumulative and iterative input of local experts, enable the collection of food group consumption data that is valid and comparable across time and geographies. The adapted survey questions have been implemented in the Demographic and Health Surveys (DHS) and Gallup World Poll in 94 countries, generating the first cross-country data on minimum dietary diversity (MDD) and other diet quality indicators. The finalized country-adapted DQQs and IYCF DQQs were translated to 143 national languages and are published online as a global public good for population-level diet quality measurement.

Development, validation, and application of a South African Dietary Polyphenol Data Quality Assessment Tool

There is a wealth of South African scientific literature studying and reporting on dietary polyphenols in research articles and academic literature. The evaluation of data quality is critical to ensure polyphenol data compiled from various scientific journals and academic texts are acceptable in terms of compilation standards. This study aimed to develop, validate, and apply a country specific South African dietary polyphenol data quality assessment tool (SADPDQAT). The evaluation tool considered nine evaluation categories with a maximum score of 5. For each literature source assessed, a quality score and confidence code was assigned. Validation analysis revealed generally consistent results between raters with an average percentage agreement of 65%, no scores falling outside of Bland-Altman limits of agreement and a moderate internal consistency α = 0.533 which was improved to 0.616. Applying the tool to 383 scientific studies showed that most literature obtained a quality score between 70 – 79% resulting in a confidence code of “B” (n= 166, 43%) and a score between 60 – 69% resulting in a confidence code of “C” (n =125, 33%). The SADPDQAT can be used to evaluate a variety of dietary polyphenol containing literature and aids in setting priorities for further research in this area.

Ultra-processed food consumption is associated with the acceleration of biological aging in the Moli-sani Study

BackgroundHealthy diets have been inversely associated with biological aging. However, the nutritional content is only one aspect of the overall food health potential, and more recently, increasing attention has been paid to nonnutrient food characteristics, such as food processing. ObjectivesTo examine the association of ultra-processed food (UPF) consumption with biological aging measured by circulating blood biomarkers. MethodsCross-sectional analyses were conducted on 22,495 participants enrolled in the Moli-sani Study (2005–2010, Italy). Food intake was assessed by a 188-item food frequency questionnaire. UPF was defined according to the Nova classification and calculated as the ratio (weight ratio; %) between UPF (g/d) and total food eaten (g/d). Diet quality was assessed by the Mediterranean Diet Score (MDS; ranging 0–9). A deep neural network approach based on 36 circulating biomarkers was used to compute biological age (BA), and the resulting difference (Δage = BA − chronological age)—an index of biological aging—was tested as dependent variable in multivariable linear regression analyses including known risk factors. ResultsThe mean Δage in this population was −0.70 (standard deviation ±7.70) years. In multivariable-adjusted analyses, higher intake of UPF was associated with accelerated Δage [β = 0.34 years; 95% confidence interval (CI): 0.08, 0.61 for the last fifth compared with the first). This association was not linear (P value for overall association <0.001; P value for nonlinearity = 0.049). Inclusion of the MDS into the model slightly attenuated this association by 9.1% (β = 0.31 years; 95% CI: 0.04, 0.59). ConclusionsA diet rich in UPF was associated with an acceleration of biological aging in a large sample of Italian adults. The poor nutritional composition of highly processed foods weakly accounted for this association, suggesting that biological aging could be adversely influenced by nonnutrient characteristics of these foods.

Micronutrient inadequacy differs by intake of fat amount and class among adults that consume a restricted carbohydrate diet: National Health and Nutrition Examination Survey, 2007-2018

BackgroundRestricted carbohydrate diets remain among the most popular for weight loss and general health improvement. Recent evidence demonstrates that carbohydrate restricted diets are low in overall diet quality, yet their association with micronutrient inadequacy has not been well characterized at a population-level in adults in the United States. Objective1) To evaluate the prevalence of not meeting daily micronutrient recommendations in US adults that met the Acceptable Macronutrient Distribution Ranges (AMDRs) and those who restricted carbohydrate to <45% energy, and 2) examine the effect of total fat and fat class on these results for the restricted carbohydrate group. DesignThis study utilized 24-hour recall data on food and nutrient intake from respondents in the National Health and Nutrition Examination Survey (NHANES) 2007-2018. Participants/settingThis study included 15,029 respondents who were ≥20 y, had complete and reliable nutrient intake data, and were not pregnant or breastfeeding. Main outcome measuresThe main outcome was the prevalence of not meeting daily micronutrient recommendations based on Dietary Reference Intakes (DRIs). Statistical analyses performedThe National Cancer Institute’s usual intake methodology was used to estimate usual dietary intake and the prevalence of the US adult population not meeting the DRIs. ResultsCompared to participants that met the AMDRs, those that consumed restricted carbohydrate diets had greater prevalence of inadequacy (% <Estimated Average Requirement) for vitamin A (46.7% vs 33.6%), folate (12.9% vs 4.3%), vitamin C (42.5% vs 23.3%), vitamin D (64.6% vs 61.3%), magnesium (45.2% vs 41.3%), and iron (3.0% vs 1.3%), and lower prevalence of inadequacy for zinc (8.1% vs 12.2%) and vitamins B-12 (1.7% vs 2.8%; P<0.05 for all comparisons). Restricted carbohydrate diet consumers had a lower likelihood of exceeding the Adequate Intake (AI) for vitamin K (57.8% vs 67.6%) and potassium (32.1% vs 39.2%; P<0.001 for both), higher likelihood of exceeding the AI for choline (16.9% vs 5.6%, P<0.001), and a greater proportion exceeded the Chronic Disease Risk Reduction Intake (CDRR) for sodium (92.1 vs 88.5%, P<0.001). Fat amount and class in those consuming restricted carbohydrate diets modified many of these associations, but the effects were heterogenous across micronutrients. ConclusionThis study shows that there are different types of restricted carbohydrate diets that can be characterized by fat amount and class, each with their own association with micronutrient intake. This information can be used by clinicians to provide more targeted dietary counseling to their patients who restrict carbohydrates, depending on the amount and type of fat they consume.

Towards a dynamic model of indispensable amino acid requirements of the adult human: A factorial estimate of oxidative amino acid losses

BackgroundConsensus regarding the required intake of indispensable amino acids (IDAAs) and protein (representing total AAs) in the adult is lacking. Oxidation is a major, though not exclusive, source of IDAA loss in the human body and a primary factor determining requirements; a quantitative understanding of oxidative IDAA losses is required. ObjectiveTo develop a factorial diurnal model of total oxidative IDAA and protein losses in the adult human. MethodsA factorial diurnal model of oxidative losses of protein and each IDAA at maintenance was developed by estimating the magnitude and variability of sources of oxidative loss from existing literature: inevitable catabolism (constitutive oxidation of each absorbed dietary AA), and protein turnover in the postprandial and postabsorptive states. Total oxidative losses were calculated by summing individual losses, validated against published independent nitrogen balance data and compared to current IDAA requirements. ResultsThe factorial model predicted minimum oxidative total AA losses of 390±60 mg.kgBW-1.day-1, 59% of the EAR for protein. Inevitable AA oxidation and oxidation associated with postabsorptive protein turnover were the major sources of the oxidative loss for protein, at 40% and 44%, respectively. Summed oxidative IDAA losses ranged from 64% (isoleucine) to 91% (tryptophan) of current requirements. Total oxidative losses predicted by the model were significant predictors of actual experimental oxidative losses obtained by nitrogen balance (R2=0.66; p=0.049). ConclusionsThe use of a factorial model for estimation of minimum IDAA and protein oxidative losses in the adult human provides an essential starting point for an updated understanding of protein and IDAA requirements. Further iterations of the model will estimate total protein and IDAA requirements, and account for variations in dietary protein quantity and quality, as well as different populations and physiological states. Additional data, especially for inevitable oxidation in humans, and particularly with respect to individual IDAAs, are needed.

Development of an older adult Nutrition Equity Index (NEI) and association with the Healthy Eating Index (HEI) in older Black and White U.S. adults

ObjectivesWe developed a novel measure for older U.S. adults called the Nutrition Equity Index (NEI), which includes functional ability. We compared both the NEI and food insufficiency with Healthy Eating Index (HEI) scores. DesignThe Health, Aging, and Body Composition Study is a prospective, longitudinal cohort of Medicare-eligible, community-dwelling Black and White men and women. SettingPittsburgh, PA and Memphis, TN. ParticipantsParticipants (N = 2468, aged 74.7 ± 2.9 years) had baseline (1997−98) and 1-year follow-up NEI data; and 1 year follow-up for food insufficiency, key covariates, and the HEI (diet quality measure) from a 108-item interviewer-administered food frequency questionnaire. MeasurementsFood insufficiency was defined from a modified validated question on ample food amount/variety from the U.S. Department of Agriculture. NEI was constructed from 8 questions in three subdomains: food insecurity (food insufficiency, hunger, anxiety about limited food, limited money for food), food access (groceries), and food acquisition (difficulty shopping, preparing meals, carrying groceries). Final NEI categories were low nutrition equity (0), moderate nutrition equity (1), and high nutrition equity (2). Multivariable linear regression compared both NEI and food insufficiency with HEI, adjusted for sociodemographic, lifestyle and comorbidity factors. ResultsOf participants, 13.5% had food insufficiency, 12.1% had low NEI, and 32.5% had moderate NEI. Participants with food insufficiency (vs. food sufficiency) or low NEI (vs. high NEI) were more likely to be Black and have < high school education (both p < 0.0001). In minimally adjusted models, food insufficiency was associated with 2.2 point lower HEI score (p = 0.001), low NEI with 2.6 point lower HEI score (p = 0.001), and moderate NEI with 1.0 point lower HEI score (p < 0.05). Adjusting for race attenuated NEI associations with HEI to non-significance. After multivariable adjustment, food insufficiency was associated with 1.5 point lower HEI score (p = 0.03). ConclusionFood insufficiency was associated with lower dietary quality in this sample of older Black and White U.S. adults. NEI performed similarly to food insufficiency for HEI associations prior to multivariable adjustment and identified more older adults with nutrition inequity, who may be at risk for poor health outcomes.

You say potato, I say vegetable; you say tomato, I say fruit: Cognitive validity of food group-based dietary recall questions

BackgroundThere is a need for valid, standardized approach for list-based questionnaires to measure food group consumption for indicators of diet quality including dietary diversity. ObjectiveA common method for collecting dietary diversity data consists of open-ended food group questions, e.g. Yesterday, did you eat any vegetables, such as cucumber, cabbage, or celery? We sought to examine the cognitive validity of open-ended questions that require respondents to categorize foods, and closed-ended alternatives using sentinel foods. MethodsPretesting and 83 cognitive interviews were conducted in five languages in São Paulo and New York City in 2018. In structured interviews, respondents were asked to describe their thought processes in answering each question. Their feedback and responses to closed-ended and open-ended food group questions were compared. The Gallup World Poll then piloted two versions of the questionnaire in a nationally representative sample of 1,000 in Brazil in 2018. ResultsRespondents in all settings miscategorized foods when asked open-ended food group questions (0-82%, depending on the food group), respondents varied in their ability to think of other foods that belonged to specified food groups (35-50% could think of any items), and open-ended questions presented an additional cognitive burden. There were no significant differences between the results from closed-ended and open-ended questions in the national pilot test. In the context of a multi-topic survey, the finalized questionnaire took 3-5 minutes, had no additional training requirements, and enumerators reported similar ease in administration as other survey modules. ConclusionsFor data collection on food group consumption, open-ended questions requiring respondents to categorize foods present cognitive validity problems. Closed-ended questions using sentinel foods reduce or eliminate ambiguity, presenting lower cognitive burden and greater comprehension. Based on these results, the closed-ended method has been adopted in international survey platforms for measuring dietary diversity and other aspects of diet quality.

Near-infrared spectroscopy for analysing livestock diet quality: A systematic review

Near-infrared spectroscopy (NIRS) is a non-invasive and fast technology that has been increasingly used to analyse livestock diet quality. The objective of this study was to conduct a systematic review of the literature to examine the utilisation of NIRS technology for analysing livestock diet quality, with a focus on identifying trends, methodologies, and challenges in recent research. We conducted a systematic search of the literature on five electronic databases and retrieved 718 studies that have been published on the subject. Fifty-four studies were subsequently selected and investigated in depth. These studies were categorised into two groups, namely benchtop and portable, based on the types of NIRS devices utilised, with a majority employing the reflectance spectra mode. Our analysis found that standard normal variate (SNV), detrend (DT), and multiplicative scatter correction (MSC) are the most commonly used spectral data processing methods. The findings indicate that NIRS technology can provide accurate and reliable measurements of key livestock diet quality parameters such as crude protein, fibre, and moisture content. Additionally, we discuss the challenges associated with NIRS technology and provide recommendations for future research directions to further advance the use of NIRS technology in the livestock industry.

Estimating young children’s exposure to food and beverage marketing on mobile devices

BackgroundFood and beverage marketing drives poor diet quality and obesity risk among children. However, it is unknown how much young children are exposed to digital food and beverage marketing on mobile devices like tablets and smartphones. ObjectiveEstimate how frequently young children, who are particularly vulnerable to advertising, view food and beverage marketing while using mobile devices. MethodsSeventy-five 2-11 year-olds and their parents from Massachusetts participated in this cross-sectional study from 2022-2023. Average estimated exposure to food and beverage advertisements and food/beverage brand appearances was calculated for 5 consecutive days using a combination of battery screenshots and average estimates of marketing collected from children’s devices. Generalized estimating equations tested for sociodemographic differences in advertising exposure. ResultsYoung children’s estimated exposure to food and beverage advertisements and brand appearances on mobile devices was highly variable, with many children seeing none on a given day but a substantial minority viewing large amounts. Estimated exposure depended on how much a child used either YouTube or a gaming app; there was no exposure on other apps used by children. Higher parental educational attainment was associated with substantially reduced risk of a child viewing two or more food or beverage advertisements or brand appearances on a given day (aOR=0.26, 95%CI: 0.10, 0.70). ConclusionsCertain children, particularly those from households with lower parental educational attainment, may be at risk for high exposure to digital food and beverage marketing, while other children may have minimal risk. Future research should explore exposure in more diverse samples with valid, feasible measures. SummaryAmong n=75 2-11 year-olds, children’s estimated exposure to digital food/beverage marketing on digital screen devices varied widely. Lower parental education was associated with higher child exposure to food/beverage marketing.

Unhealthy Dietary Pattern Associated with Common Mental Disorders in Adults and Older Adults: A Population-based Study

Background:: Mental and behavioral disorders are influenced by biological, psychological and social factors, especially income, gender, age and family environment, indicating that physical health is directly associated with mental health. In this perspective, food consumption is highlighted as a risk factor for mental health, as healthy behaviors, along with a good quality diet, can reduce symptoms of anxiety and depression. Objective:: The objective of this a study is to investigate the association between CMD and dietary patterns, among other lifestyle and socioeconomic factors. Method:: Cross-sectional population-based and household study conducted with 1574 individuals aged over 20 years, of both sexes, residing in Teresina and Picos, Piaui, Brazil. Sociodemographic, lifestyle and food consumption data were collected. The instrument used to identify the presence of CMDs was the Self Reporting Questionnaire 20 (SRQ-20). Dietary patterns were obtained using the Principal Component Analysis method. Results:: Individuals of female sex, separated, with low education, smokers and lower level of physical activity had a higher prevalence of common mental disorders. As for the eating pattern, after adjustments, individuals who adhered to the unhealthy eating pattern had a 9% higher prevalence of CMD. Furthermore, adherence to the white meat standard represented 12% higher prevalence of CMD. Conclusion:: The results showed that, regardless of other socioeconomic and lifestyle factors, adherence to a more monotonous eating pattern in foods, characterized by the mainly consumption of animal protein and the lack consumption of foods like fruits and vegetables, as well as a less healthy one, characterized by the consumption of ultra-processed foods, increases the risk of developing CMD.
