Adolescent nutritional behaviors are assuming considerable importance in nutrition interventions given their important relationships with medium- and long-term outcomes. This is the period when young people undergo major anatomical and physiological maturational changes in preparation for adulthood. Nutritional requirements during puberty are higher during adolescence than during the prepubertal stage and during adulthood. A significant proportion of adolescents also become parents, and hence the importance of their health and nutritional status before as well as during pregnancy has its impact on their own health, fetal well-being, and newborn health. In this paper, we describe the evidence-based nutrition recommendations and the current global guidance for nutrition actions for adolescents. Despite the limitations of available information, we believe that a range of interventions are feasible to address outcomes in this age group, although some would need to start earlier in childhood. We propose packages of preventive care and management comprising nutrition-specific and nutrition-sensitive interventions to address adolescent undernutrition, overnutrition, and micronutrient deficiencies. We discuss potential delivery platforms and strategies relevant to low- and middle-income countries. Beyond the evidence synthesis, there is a clear need to translate evidence into policy and for implementation of key recommendations and addressing knowledge gaps through prioritized research.
Strategies to address the nutritional needs of adolescent girls and young women often focus on supplementation. In this study, an action-research approach involving a nutrition education and entrepreneurship intervention was carried out among adolescent girls and young women in poor neighborhoods of Medellín, Colombia. The intervention group significantly increased its intake of several nutrients, including energy, protein, total fat, saturated fat, monounsaturated fat, polyunsaturated fat, cholesterol, dietary fiber, calcium, zinc, and vitamins A, B2, B3, B9, and C. A significant increase was observed in the intake of the Global Diet Quality Score (GDQS) healthy food groups (other fruits, other vegetables, legumes, high-fat dairy products), accompanied by a decrease in the consumption of some unhealthy food groups (sweets and ice creams). A multivariate regression controlling for age, socioeconomic status, occupation, Household Hunger Scale, mean probability of adequacy, physical activity, and body self-perception showed that the nutrition intervention improved the total GDQS by 33% in the intervention group-a substantial improvement notwithstanding the study group's precarious social and economic conditions. We conclude that nutrition education and entrepreneurship models based on this approach may improve the dietary profile of this population and reduce future pressures from nutrition-related chronic diseases.
Despite the global transition to overnutrition, stunting affected approximately 159 million children worldwide in 2014, while an estimated 50 million children were wasted. India is an important front in the fight against malnutrition and is grappling with the coexistence of undernutrition, overnutrition, and micronutrient deficiencies. This report summarizes discussions on trends in malnutrition in India, its evolution in the context of economic growth, intrahousehold aspects, infant and young child feeding practices, women's status, maternal nutrition, and nutrition policymaking. The discussion focuses on a review of trends in malnutrition and dietary intakes in India in the context of economic change over the past four decades, identification of household dynamics affecting food choices and their consequences for family nutritional status in India, and effective malnutrition prevention and treatment interventions and programs in India and associated policy challenges.
Prenatal micronutrient deficiencies are associated with negative maternal and birth outcomes. Multiple micronutrient supplementation (MMS) during pregnancy is a cost-effective intervention to reduce these adverse outcomes. However, important knowledge gaps remain in the implementation of MMS interventions. The Child Health and Nutrition Research Initiative (CHNRI) methodology was applied to inform the direction of research and investments needed to support the implementation of MMS interventions for pregnant women in low- and middle-income countries (LMIC). Following CHNRI methodology guidelines, a group of international experts in nutrition and maternal health provided and ranked the research questions that most urgently need to be resolved for prenatal MMS interventions to be successfully implemented. Seventy-three research questions were received, analyzed, and reorganized, resulting in 35 consolidated research questions. These were scored against four criteria, yielding a priority ranking where the top 10 research options focused on strategies to increase antenatal care attendance and MMS adherence, methods needed to identify populations more likely to benefit from MMS interventions and some discovery issues (e.g., potential benefit of extending MMS through lactation). This exercise prioritized 35 discrete research questions that merit serious consideration for the potential of MMS during pregnancy to be optimized in LMIC.
Adolescent and young women face grave nutrition challenges, but limited evidence exists on solutions to improve their diets. Action-research was done over 3 years (2020-2022) in secondary cities of Colombia (Medellin) and Vietnam (Thai Nguyen) to identify nutrient deficits in adolescent and young women diets; elaborate food-based recommendations to improve their nutritional status using Optifood linear programming; and engage respondents in incorporating suggested recommendations to their diet using a Social Innovation Challenge approach. A total of 1001 respondents were interviewed in Vietnam, 793 in Colombia. The probability of nutrient inadequacy in both locations was highest for iron and calcium, followed by the risk of deficiency for several other vitamins and minerals. Social Innovation Challenge teams (11 in Vietnam, 9 in Colombia) were created and supported in developing solutions to improve diets and tackle those deficiencies. Awards and resources were transferred to the most promising solutions to enable their implementation. Pre/post measurements of the interventions' impact using the Global Diet Quality Score as outcome metric showed significant improvement in the diets of Challenge participants. After introducing a series of companion articles that offer detailed results on those various steps, this paper draws strategic lessons from an action-research perspective.
Globally, dietary intake of calcium is often insufficient, and it is unclear if adequacy could be achieved by promoting calcium-rich local foods. This study used linear programming and household consumption data from Uganda, Bangladesh, and Guatemala to assess whether local foods could meet calcium population reference intakes (Ca PRIs). The most promising food-based approaches to promote dietary calcium adequacy were identified for 12- to 23-month-old breastfed children, 4- to 6-year-old children, 10- to 14-year-old girls, and nonpregnant and nonbreastfeeding (NPNB) women of reproductive age living in two regions of each country. Calcium-optimized diets achieved 75-253% of the Ca PRI, depending on the population, and were <100% for 4- to 6-year-olds in one region of each country and 10- to 14-year-old girls in Sylhet, Bangladesh. The best food sources of calcium were green leafy vegetables and milk, across geographic locations, and species of small fish, nixtamalized (lime-treated) maize products, sesame seeds, and bean varieties, where consumed. Food-based recommendations (FBRs) achieving the minimum calcium threshold were identified for 12- to 23-month-olds and NPNB women across geographic locations, and for 4- to 6-year-olds and 10-to 14-year-old girls in Uganda. However, for 4- to 6-year-olds and 10- to 14-year-old girls in Bangladesh and Guatemala, calcium-adequate FBRs could not be identified, indicating a need for alternative calcium sources or increased access to and consumption of local calcium-rich foods.
Recent advances in the diagnosis and management of reflux disease were the central focus of the inaugural Gatherings in Esophagology (GiE), which convened experts across gastroenterology, surgery, otolaryngology, pulmonology, and basic research. The sessions highlighted innovations in reflux monitoring-including high-resolution manometry, wireless pH monitoring, and novel salivary biomarkers-while critically evaluating their diagnostic accuracy and clinical utility. Presentations explored the limitations of traditional proton-pump inhibitor therapy, the emergence of potassium-competitive acid blockers as a new class of acid suppressants, and the evolving role of adjunctive treatments such as mucosal protectants, reflux reducers, and neuromodulators for refractory symptoms. The discourse extended to advanced interventional procedures, including transoral incisionless fundoplication, magnetic sphincter augmentation, and the RefluxStop device, with discussion of patient selection, efficacy, and complication management. Discussants emphasized the pathophysiology and management of extraesophageal manifestations of reflux, the interplay between reflux and pulmonary disease, and the diagnostic challenges in pediatric populations. The meeting also addressed the integration of behavioral therapies, the role of the microbiome, and the application of artificial intelligence in reflux diagnostics. Collectively, these insights underscore a shift toward precision medicine in reflux disease, emphasizing individualized diagnostic strategies and tailored therapeutic approaches to improve patient outcomes.
Nutrition modeling tools (NMTs) generate evidence to inform policy and program decision making; however, the literature is generally limited to modeling methods and results, rather than use cases and their impacts. We aimed to document the policy influences of 12 NMTs and identify factors influencing them. We conducted semistructured interviews with 109 informants from 30 low- and middle-income country case studies and used thematic analysis to understand the data. NMTs were mostly applied by international organizations to inform national government decision making. NMT applications contributed to enabling environments for nutrition and influenced program design and policy in most cases; however, this influence could be strengthened. Influence was shaped by processes for applying the NMTs; ownership of the analysis and data inputs, and capacity building in NMT methods, encouraged uptake. Targeting evidence generation at specific policy cycle stages promoted uptake; however, where advocacy capacity allowed, modeling was embedded ad hoc into emerging policy discussions and had broader influence. Meanwhile, external factors, such as political change and resource constraints of local partner organizations, challenged NMT implementation. Importantly, policy uptake was never the result of NMTs exclusively, indicating they should be nested persistently and strategically within the wider evidence and advocacy continuum, rather than being stand-alone activities.
Alzheimer's disease (AD) is a major source of morbidity and mortality, with the disease burden expected to rise as the population ages. No disease-modifying agent is currently available, but recent research suggests that nutritional and lifestyle modifications can delay or prevent the onset of AD. However, preventive nutritional interventions are not universally applicable and depend on the clinical profile of the individual patient. This article reviews existing nutritional modalities for AD prevention that act through improvement of insulin resistance, correction of dyslipidemia, and reduction of oxidative stress, and discusses how they may be modified on the basis of individual biomarkers, genetics, and behavior. In addition, we report preliminary results of clinical application of these personalized interventions at the first AD prevention clinic in the United States. The use of these personalized interventions represents an important application of precision medicine techniques for the prevention of AD that can be adopted by clinicians across disciplines.
Poor representation of racial/ethnic minority groups limits the validity and generalizability of clinical trials and contributes to inequities in medicine and science. To recruit a multicultural sample of mid-life individuals using multiple recruitment modalities for a randomized controlled trial of diet and cognition comparing an anti-inflammatory dietary intervention versus usual diet and the effect on cognition. This study describes the utility of various modalities to recruit a multi-cultural cohort. Recruitment techniques, the success rate of each, and characteristics of participants are compared to representative Bronx U.S. Census statistics. Participants were identified in target communities using voter registration rolls paired with marketing lists and enriched patient lists extracted from electronic health records of mid-life (40-65 years) adults in Bronx, New York. Outreach activities, including print and social media, supplemented these lists to promote the study. Over 4 years of recruitment, invitation letters, followed by telephone calls, yielded the highest number of randomized recruits, with 80.5% of participants recruited prior to the pandemic and 90.1% during the pandemic. A total of 290 participants enrolled in proportion to the racial/ethnic breakdown of targeted Bronx communities. However, women were overrepresented compared to the overall Bronx population. Each recruitment modality had strengths and weaknesses. The combination resulted in reaching an important sector of the population that could benefit from interventions. Voter registration lists reached a broad spectrum of targeted communities and resulted in enrollment and randomization of the majority of participants. Online registries (e.g., ResearchMatch) and outreach activities yielded efficient enrollment. Our multi-pronged strategy led to successful enrollment of a multi-cultural sample. Although the systematic list approach was the most productive, the importance of reaching out to community was crucial. Refining techniques of online registries, working with trusted community organizations, continuous assessment, and experimentation with other modalities may be helpful. ADRD affects US minority populations disproportionately.Multiple recruitment methods help engage the underrepresented in clinical trials.Use of voter registration and EHR lists allow recruiters to reach a wide and heterogenous audience.Letters followed by personal phone calls are effective in recruitment.Outreach to the community provides a person-to-person connection to the study.
The relationships between 24-h time-use composition (i.e., sleep, sedentary behavior, light physical activity, and moderate-to-vigorous physical activity [MVPA]) and brain morphology in older adulthood remain poorly understood. We examined associations between 24-h time-use composition and brain age using compositional data analysis, predicting that 24-h time use would be associated with brain age and that a greater amount of time engaged in MVPA would drive associations with younger brain age. Baseline data from the Investigating Gains in Neurocognition in an Intervention Trial of Exercise (IGNITE; n = 648) were analyzed. Brain age was estimated using T1-weighted magnetic resonance imaging data. Time-use composition was derived from wrist-worn triaxial accelerometers. Regression models examined associations between 24-h time-use composition (expressed as isometric log ratios) and brain age, adjusting for age, sex, apolipoprotein E4 (APOE4) carriage, education, body mass index, image quality, and site. Compositional isotemporal substitution evaluated how hypothetical reallocations of time between behaviors related to brain age. The final sample included 573 adults (69.8±3.7 years, 407 females). It was found that 24-h time-use composition was associated with brain age (F = 2.72, p = 0.004). Post hoc modeling indicated that time spent in MVPA primarily drove these associations, such that less MVPA was associated with greater brain age, irrespective of whether time was taken from sleep, sedentary behavior, or light physical activity. These results suggest that 24-h time use, especially time spent in MVPA, relates to structural brain age in late adulthood. Maintaining or increasing MVPA may help preserve younger brain age, irrespective of which behaviors this time was reallocated from. Future research should examine whether systematically shifting 24-h time use toward MVPA alters brain aging trajectories.Clinical Trial Registration Number and Name of Trial Registry: ClinicalTrial.gov: NCT02875301. Time use relates to brain age in older adults.More time spent in MVPA may contribute to younger brain age.Associations between time use and brain age are independent of demographic variation or genetic risk for AD.
Optimizing second-line therapy for type 2 diabetes is challenging due to interindividual variability in response. We conducted a pharmacogenomic genome-wide association study (GWAS) in the Glycemia Reduction Approaches in Type 2 Diabetes: A Comparative Effectiveness (GRADE) Study to identify genetic predictors of glycemic response to insulin glargine, glimepiride, liraglutide, and sitagliptin, when added to metformin in a diverse population. We identified 21 genome-wide significant loci associated with treatment response. rs1905505, a non-coding variant near SLC2A2, the gene encoding the glucose transporter GLUT2, was enriched in Africans/African Americans and conferred a 36% increased risk of treatment failure on glimepiride (p=4.83×10). Carriers had impaired β-cell function, evidenced by a lower C-peptide index during OGTT, and diminished glucose-lowering response to an acute sulfonylurea challenge. Genetic manipulation in zebrafish confirmed that slc2a2 disruption attenuates the glucose-lowering effect of glimepiride. In conclusion, genetic variation influences glycemic response to medications, with SLC2A2 emerging as a key determinant of sulfonylurea response. NCT01794143.
Esophagogastric junction outflow obstruction (EGJOO) is a heterogeneous disorder characterized by abnormal esophagogastric junction residual pressures in the setting of intact esophageal body peristalsis. This manometric finding is most clinically relevant in patients with dysphagia and chest pain, and may arise from various mechanisms, including structural processes, catheter positioning artifact, and medications. Rarely, manometric EGJOO is a consequence of abnormal relaxation of the lower esophageal sphincter (LES) akin to achalasia. Thus, it is critical in the evaluation of EGJOO to determine if a true pressure gradient exists across the esophagogastric junction (EGJ) that warrants therapy. There are many unanswered questions in EGJOO diagnosis and management, which are addressed in this review in the context of the use of provocative maneuvers during high-resolution manometry, complementary and alternate testing, and therapeutic options.
The circular bionutrient economy is defined here as the circular economy of nutrients in managed organic residues. Here, we posit that biochar technology can stimulate the circular bionutrient economy by meeting the following three requirements: 1) nutrients are captured in a dry form, increasing market value and lowering transportation cost; 2) individual nutrients can be captured separately and combined as needed for particular plants and soils; 3) all pathogens and most pollutants can be removed with the notable exception of heavy metals. Pyrolysis and associated moisture removal enabled by the energy released during pyrolysis decreases weight of solid excreta by 85 to 90% and volume by 74 to 90%. This will lower storage and transport costs allowing redistribution of nutrients from production to processing and consumption of food. Incorporating liquid organic residues into nutrient recovery processes is crucial to the circular bionutrient economy. For example, N fertilizer from human feces would only generate about 2% (2.0 to 2.4 Tg N y-1) of current global N application, whereas including urine could increase this fraction to 16 to 17% (15.7 to 16.9 Tg N y-1). Nutrient acquisition by plants can be increased by biochar through nutrient retention and pH buffering in soil. We posit that leveraging biochar to close the nutrient circle requires public-private partnerships in forms of a community of practice and green alliances. These must develop a marketable product that incentivizes private investment. Such products may only be cost competitive with established fertilizer products by internalizing external environmental costs possibly through market mechanisms including but not limited to carbon credits.
Nutritional imbalance in adolescent girls causes alterations in health, reproductive cycles, and fetal outcomes of future generations. To evaluate the dietary pattern and prevalence of inadequate nutrient intake, a 24-hour multi-step food recall was carried out among 793 adolescent women (14-20 years old) from Medellin, Colombia. Their dietary pattern was characterized by lower than recommended intakes of fruits and vegetables (CRI 0.4, AMD 0.2), dairy (CRI 0.5, AMD 0.2), and proteins (CRI 0.8, AMD 0.3), while starches (CRI 1.2, AMD 0.4), fats (CRI 1.1, AMD 0.6), and sugars (CRI 1.0, AMD 0.5) were at similar or higher levels than recommendations. A high risk of deficiency was found in the usual intake of energy (53.0%), protein (39.8%), calcium (98.9%), folates (85.7%), iron (74.4%), thiamine (44.3%), vitamin C (31.3%), zinc (28.3%), vitamin A (23.4%), cyanocobalamin (17.3%), and pyridoxine (10.9%). A low risk of deficiency was noted in usual fiber intake (0.5%), and a higher than recommended intake was noted in saturated fat (100.0%) and simple carbohydrates (68.8%). Anecdotally, a large proportion of respondents saw decreases in their food consumption during the COVID-19 pandemic. These results suggest an urgent need for nutrition education programs to emphasize the importance of adequate nutrition among adolescent women.
High Lp(a) levels contribute to atherosclerotic cardiovascular disease and are tightly regulated by the LPA gene . Lp(a) levels have an inverse correlation with LPA Kringle IV Type-2 (KIV-2) copy number (CN). Black (B) and Hispanic (H) individuals exhibit higher levels of Lp(a), and rates of CVD compared to non-Hispanic Whites (NHW). Therefore, we investigated genetic variations in the LPA KIV-2 region across three ancestries and their associations with metabolic risk factors. Using published pipelines, we analyzed a multi-ethnic whole exome dataset comprising 3,817 participants from the Washington Heights and Inwood Columbia Aging Project (WHICAP): 886 [NHW (23%), 1,811 Caribbean (C) H (47%), and 1,120 B individuals (29%). Rare and common variants (alternative allele carrier frequency, CF < 0.01 or > 0.99 and 0.01 < CF < 0.99, respectively) were identified and KIV-2 CN estimated. The associations of variants and CN with history of heart disease, hypertension (HTN), stroke, lipid levels and clinical diagnosis of Alzheimer's disease (AD) was assessed. A small pilot provided in-silico validation of study findings. We report 1421 variants in the LPA KIV-2 repeat region, comprising 267 exonic and 1154 intronic variants. 61.4% of the exonic variants have not been previously described. Three novel exonic variants significantly increase the risk of HTN across all ethnic groups: 4785-C/A (frequency = 78%, odds ratio [OR] = 1.45, p = 0.032), 727-T/C (frequency = 96%, OR = 2.11, p = 0.032), and 723-A/G (frequency = 96%, OR = 1.97, p = 0.038). Additionally, six intronic variants showed associations with HTN: 166-G/A, 387-G/C, 402-G/A, 4527-A/T, 4541-G/A, and 4653-A/T. One intronic variant, 412-C/T, was associated with decreased blood glucose levels (frequency = 72%, β = -14.52, p = 0.02).Three of the associations were not affected after adjusting for LPA KIV-2 CN: 412-C/T (β = -14.2, p = 0.03), 166-G/A (OR = 1.41, p = 0.05), and 387-G/C (OR = 1.40, p = 0.05). KIV CN itself was significantly associated with 314 variants and was negatively correlated with plasma total cholesterol levels. In three ancestry groups, we identify novel rare and common LPA KIV-2 region variants. We report new associations of variants with HTN and Glucose levels. These results underscore the genetic complexity of the LPA KIV-2 region in influencing cardiovascular and metabolic health, suggesting potential genetic regulation of pathways that can be studied for research and therapeutic interventions.
It is unclear whether the association between Mediterranean-type Diet (MeDi) and cognition is similar across different racial/ethnic groups or between women and men. The current study included 2435 participants (≥60 years of age) of the National Health and Nutrition Examination Survey (NHANES) 2011-2014. Linear regression models were applied to examine the association between diet and cognition, adjusted for multiple demographic variables. Interaction between MeDi and race/ethnicity (non-Hispanic White, non-Hispanic Black, Hispanic, other), and between MeDi and gender, were examined, followed by stratified analyses. One score increase in MeDi was associated with 0.039 (95%confidence interval [CI] = 0.016-0.062) higher global cognitive z-score. Significant associations between MeDi and global cognition and between MeDi and immediate recall were found in the non-Hispanic Whites only (P-interaction = 0.057 and 0.059, respectively). MeDi was associated with increased score of animal fluency score in men but not in women (P-interaction = 0.082). The positive association between MeDi and cognition might be dependent on race/ethnicity and gender.
Lipoprotein (a) [Lp(a)] is an apoB100-containing lipoprotein with high levels being positively associated with atherosclerotic cardiovascular disease. Lp(a) levels are genetically determined. However, previous studies report a negative association between Lp(a) and saturated fatty acid intake. Currently, apoB100 lowering therapies are used to lower Lp(a) levels, and apheresis therapy is FDA approved for patients with extreme elevations of Lp(a). The current study analyzed the association of free-living diet components with plasma Lp(a) levels. Dietary composition data was collected during screening visits for enrollment in previously completed lipid and lipoprotein metabolism studies at Columbia University Irving Medical Center via a standardized protocol by registered dietitians using 24 hour recalls. Data were analyzed with the Nutrition Data System for Research (Version 2018). Diet quality was calculated using the Healthy Eating Index (HEI) score. Fasting plasma Lp(a) levels were measured via an isoform-independent ELISA and apo(a) isoforms were measured using gel electrophoresis. We enrolled 28 subjects [Black (n = 18); Hispanic (n = 7); White (n = 3)]. The mean age was 48.3 ± 12.5 years with 17 males. Median level of Lp(a) was 79.9 nmol/L (34.4-146.0) and it was negatively associated with absolute (grams/day) and relative (percent of total calories) intake of dietary saturated fatty acids (SFA) (R = -0.43, P = 0.02, SFA …(% CAL): R = -0.38, P = 0.04), palmitic acid intake (R = -0.38, P = 0.05), and stearic acid intake (R = -0.40, P = 0.03). Analyses of associations with HEI score when stratified based on Lp(a) levels > or ≤ 100 nmol/L revealed no significant associations with any of the constituent factors. Using 24 hour recall, we confirm previous findings that Lp(a) levels are negatively associated with dietary saturated fatty acid intake. Additionally, Lp(a) levels are not related to diet quality, as assessed by the HEI score. The mechanisms underlying the relationship of SFA with Lp(a) require further investigation.
Policymakers are committed to improving nutritional status and to saving lives. Some micronutrient intervention programs (MIPs) can do both, but not to the same degrees. We apply the Micronutrient Intervention Modeling tool to compare sets of MIPs for (1) achieving dietary adequacy separately for zinc, vitamin A (VA), and folate for children and women of reproductive age (WRA), and (2) saving children's lives via combinations of MIPs. We used 24-h dietary recall data from Cameroon to estimate usual intake distributions of zinc and VA for children 6-59 months and of folate for WRA. We simulated the effects on dietary inadequacy and lives saved of four fortified foods and two VA supplementation (VAS) platforms. We estimated program costs over 10 years. To promote micronutrient-specific dietary adequacy, the economic optimization model (EOM) selected zinc- and folic acid-fortified wheat flour, VA-fortified edible oils, and bouillon cubes, and VAS via Child Health Days in the North macroregion. A different set of cost-effective MIPs emerged for reducing child mortality, shifting away from VA and toward more zinc for children and more folic acid for WRA. The EOM identified more efficient sets of MIPs than the business-as-usual MIPs, especially among programs aiming to save lives.
The Global Diet Quality Score (GDQS) has been recommended as a simple diet quality metric that is reflective of both nutrient adequacy and noncommunicable disease outcomes. It has been validated among women of reproductive age (15-49 years) in diverse settings but not specifically among younger women. This paper examines the relationship between the GDQS and nutrient adequacy, anthropometric outcomes, and depressive symptoms among 1001 Vietnamese young women aged 16-22 years. In energy-adjusted models, the GDQS was significantly (p < 0.05) and positively correlated with intakes of protein (ρ = 0.23), total fat (ρ = 0.06), nine micronutrients (calcium, iron, zinc, vitamin C, riboflavin, niacin, vitamin B6, folate, and vitamin A) (ρ = 0.12-0.35), and the mean probability of adequacy of micronutrients (ρ = 0.28). Compared to young women with optimal GDQS, those with low and very low GDQS were two to five times more likely to have a mean probability of nutrient adequacy less than 50% and showed two to three times higher odds for depression. No association was observed for GDQS and anthropometric outcomes. In conclusion, the GDQS performed well in capturing nutrient adequacy and depressive symptoms among Vietnamese young women. Further research is warranted to explore the relationship between diet quality and depression in other settings.
