RESUMO
PURPOSE: This study aimed to estimate the health, economic, and environmental impacts of moderate simulated interventions on dietary intake in Brazil. METHODS: Data on food price and consumption were obtained from three nationwide surveys. Baseline dietary intake was estimated for 33,859 individuals aged 25 years and older. Counterfactual intakes were based on six hypothetical intervention scenarios, by changing the weekly frequency and serving size in low or high consumers of fruit and vegetables (FV), milk, whole grains, red and processed meats, and sugar-sweetened beverages. For each scenario, we estimated the attributable number of deaths and disability-adjusted life years (DALY), monetary cost, environmental impacts (14 midpoint indicators), and environmentally-mediated health impacts. RESULTS: Compared with the baseline intake and cost, the most expensive intervention (+ 8.3%) was to increase FV intake (+ 125 g), resulting in a 1.2% reduction in all-cause mortality (16,307 deaths/year). The cheapest (- 9.9%) was to reduce red and processed meat intake (- 40 g), resulting in a 1.1% reduction in all-cause mortality (14,272 deaths/year). The combined intervention was, on average, 3.7% cheaper than the baseline cost, resulting in an increase in diet cost for 30% of the population (45-22% in the lower- and higher-income groups); all-cause mortality would be reduced by 3.8% (49,488 deaths/year). Interventions targeting red and processed meats would reduce emissions and resource use by 35-55%, in addition to reducing 2300 DALYs/year. CONCLUSION: A meaningful number of deaths can be avoided and environmental impacts reduced through moderate and potentially affordable diet modifications.

BACKGROUND: Adequate nutrition has been cited as one of the most critical components for optimal health outcomes during pregnancy. Women in Burkina Faso and Madagascar experience high rates of undernutrition due to lack of knowledge, finances, cultural norms, and autonomy. Therefore, this study aimed (1) to describe typical maternal diets during pregnancy in Burkina Faso and Madagascar, (2) to understand the multilevel factors that influence women's nutrition decision-making, and (3) to explore the extent to which women have nutrition decision-making autonomy during pregnancy. METHODS: This study was conducted between October 2020 and February 2021 in Burkina Faso and Madagascar. Semi-structured interviews, focus group interviews, and free lists were conducted among women of reproductive age and pregnant and lactating women. Textual data from interviews were recorded and translated verbatim from local languages into French. The Food Choice Process Model guided textual content analysis using Dedoose software. Free list data were analyzed using cultural domain analysis approaches. RESULTS: In Burkina Faso and Madagascar, women primarily consumed staple foods such as rice and tô during pregnancy. Participants cited eating fruits and vegetables when available, while the animal source foods were rarely consumed. Across both contexts, nutrition during pregnancy was influenced by factors that impact food choices, such as social factors, resources, ideals, and personal factors. While women and men in Madagascar had more shared decision-making on critical domains such as finances, men were the primary decision-makers in most areas of inquiry (eg, finances) in Burkina Faso. CONCLUSIONS: The lack of adequate diverse diet consumed during pregnancy is primarily due to important factors including social factors and resources. Understanding the ability for women to consume optimal diets during pregnancy is needed to target behavioral change in maternal nutrition programming.
Plain language titleA comparison of How Pregnant Women Make Decisions About What to Eat in Burkina Faso and Madagascar Using a Model Called the Food Choice Process ModelPlain language summaryHaving a proper diet is very important for the health of pregnant women. In Burkina Faso and Madagascar, many women do not get enough nutritious food due to lack of knowledge on what to eat, lack of money, cultural traditions, and not having control over their own choices. This study wants to find out (1) what women eat during pregnancy in Burkina Faso and Madagascar, (2) what influences the decisions women make about what to eat during pregnancy, and (3) explore how women had decision-making autonomy during pregnancy. The study took place in Burkina Faso and Madagascar. The researchers talked to women who could have babies and women who were already pregnant or breastfeeding. They used different methods like focus group discussions and semi-structured interviews to gather information. They recorded and translated everything that was said from the local languages to French. They used special software to analyze the information from the interviews. They also used a free list to understand the things women mentioned most often when talking about food. In Burkina Faso and Madagascar, women mostly ate basic foods like rice and tô during pregnancy. Sometimes they ate fruits and vegetables when they were available, but they did not eat much meat or other foods from animals. In both places, the women's food choices during pregnancy were influenced by different things like what their friends and family thought, how much money they had, their personal preferences, and other factors. In Madagascar, men and women made decisions together about important things like money, but in Burkina Faso, men were usually the ones making the decisions. The lack of a proper diverse diet during pregnancy in Burkina Faso and Madagascar is primarily caused by social factors and resources. To help women make better food choices during pregnancy, it's important to understand what affects their ability to have a healthy diet. This can help programs that aim to improve the nutrition of pregnant women by encouraging them to change their behavior.

The purpose of the current study was to describe the design, development, and validation of the 'Diet DQ Tracker'. The 'Diet DQ Tracker' is the first self-administered smartphone app designed to collect dietary data for diet diversity indicators. The main objective of the app was to replace the traditional methods of dietary data collection, such as in-person or telephone 24 h recall via pen and paper questionnaire or tablets. The real-time meal recording, extensive food database, and automatic score calculations and visualizations for MDD-W, IYCF-MDD, and HDDS have the potential to overcome the drawbacks of 24 h recalls. Recall depends on respondent memory, food expertise, and time consumption and demands skilled interviewers. Further, SAIN, LIM recommendations in the app prompt users to diversify diets with healthy foods. The pilot study determined the acceptability, feasibility, and relative validity of the 'Diet DQ Tracker' with a 24 h dietary recall. The results demonstrated minimal differences in dietary scores by both methodologies. The app, being convenient, easy to use, less time-consuming, and enjoyable, was preferred by the entire study sample over 24 h recall. The app will be continually updated with foods from different cultures for validating in large-scale studies. The future studies will help to improve the subsequent versions of the app.

The assessment of dietary carotenoids via blood measurements has been widely used as a marker for fruit and vegetable consumption. In the present study, modern, non-invasive approaches to assess dietary carotenoids, such as skin measurements and an app-based short dietary record (ASDR), were compared with conventional methods such as plasma status and handwritten 3-day dietary records. In an 8-week observational study, 21 healthy participants aged 50-65 years recorded their daily consumption of carotenoid-rich fruits and vegetables via a specially developed ASDR. Anthropometry, blood samplings and assessment of skin carotenoids via Raman and reflection spectroscopy were performed at baseline, after four weeks and at the end of the study. App-based intake data showed good correlations with plasma α-carotene (r = 0.74, p < 0.0001), ß-carotene (r = 0.71, p < 0.0001), and total plasma carotenoids (r = 0.65, p < 0.0001); weak correlations with plasma lutein/zeaxanthin and ß-cryptoxanthin (both r = 0.34, p < 0.05); and no correlation with plasma lycopene. Skin measurements via reflection and Raman spectroscopy correlated well with total plasma carotenoids (r = 0.81 and 0.72, respectively; both p < 0.0001), α-carotene (r = 0.75-0.62, p < 0.0001), and ß-carotene (r = 0.79-0.71, p < 0.0001); moderately with plasma lutein/zeaxanthin (both r = 0.51, p < 0.0001); weakly with plasma ß-cryptoxanthin (r = 0.40-0.31, p < 0.05); and showed no correlation with plasma lycopene. Skin measurements could provide a more convenient and noninvasive approach of estimating a person's fruit and vegetable consumption compared to traditional methods, especially in studies that do not intend blood sampling. ASDR records might function as a suitable, convenient tool for dietary assessment in nutritional intervention studies.

BACKGROUND: Conventional dietary assessment methods are affected by measurement errors. We developed a smartphone-based 2-h recall (2hR) methodology to reduce participant burden and memory-related bias. OBJECTIVE: Assessing the validity of the 2hR method against traditional 24-h recalls (24hRs) and objective biomarkers. METHODS: Dietary intake was assessed in 215 Dutch adults on 6 randomly selected nonconsecutive days (i.e., 3 2hR-days and 3 24hRs) during a 4-wk period. Sixty-three participants provided 4 24-h urine samples, to assess urinary nitrogen and potassium concentrations. RESULTS: Intake estimates of energy (2052±503 kcal vs. 1976±483 kcal) and nutrients (e.g., protein: 78±23 g vs. 71±19 g; fat: 84±30 g vs. 79±26 g; carbohydrates: 220±60 g vs. 216±60 g) were slightly higher with 2hR-days than with 24hRs. Comparing self-reported protein and potassium intake to urinary nitrogen and potassium concentrations indicated a slightly higher accuracy of 2hR-days than 24hRs (protein: -14% vs. -18%; potassium: -11% vs. -16%). Correlation coefficients between methods ranged from 0.41 to 0.75 for energy and macronutrients and from 0.41 to 0.62 for micronutrients. Generally, regularly consumed food groups showed small differences in intake (<10%) and good correlations (>0.60). Intake of energy, nutrients, and food groups showed similar reproducibility (intraclass correlation coefficient) for 2hR-days and 24hRs. CONCLUSIONS: Comparing 2hR-days with 24hRs showed a relatively similar group-level bias for energy, most nutrients, and food groups. Differences were mostly due to higher intake estimates by 2hR-days. Biomarker comparisons showed less underestimation by 2hR-days as compared with 24hRs, suggesting that 2hR-days are a valid approach to assess the intake of energy, nutrients, and food groups. This trial was registered at the Dutch Central Committee on Research Involving Human Subjects (CCMO) registry as ABR. No. NL69065.081.19.

Blue foods, sourced in aquatic environments, are important for the economies, livelihoods, nutritional security and cultures of people in many nations. They are often nutrient rich1, generate lower emissions and impacts on land and water than many terrestrial meats2, and contribute to the health3, wellbeing and livelihoods of many rural communities4. The Blue Food Assessment recently evaluated nutritional, environmental, economic and justice dimensions of blue foods globally. Here we integrate these findings and translate them into four policy objectives to help realize the contributions that blue foods can make to national food systems around the world: ensuring supplies of critical nutrients, providing healthy alternatives to terrestrial meat, reducing dietary environmental footprints and safeguarding blue food contributions to nutrition, just economies and livelihoods under a changing climate. To account for how context-specific environmental, socio-economic and cultural aspects affect this contribution, we assess the relevance of each policy objective for individual countries, and examine associated co-benefits and trade-offs at national and international scales. We find that in many African and South American nations, facilitating consumption of culturally relevant blue food, especially among nutritionally vulnerable population segments, could address vitamin B12 and omega-3 deficiencies. Meanwhile, in many global North nations, cardiovascular disease rates and large greenhouse gas footprints from ruminant meat intake could be lowered through moderate consumption of seafood with low environmental impact. The analytical framework we provide also identifies countries with high future risk, for whom climate adaptation of blue food systems will be particularly important. Overall the framework helps decision makers to assess the blue food policy objectives most relevant to their geographies, and to compare and contrast the benefits and trade-offs associated with pursuing these objectives.

PURPOSE: To examine the associations between dietary intake as assessed by a rapid, image-based digital tool and biomarkers of cardiometabolic health. DESIGN: Retrospective analysis of adults with blood biomarkers performed by Boston Heart Diagnostics (BHD) between December 2020 and March 2022. SETTING: Outpatient centers serviced by BHD. SUBJECTS: 546 adults, excluding those taking relevant medications and/or supplements known to affect blood test results. MEASURES: Laboratory assays of blood specimens were performed by Boston Heart Diagnostics. Nutrient intake and diet quality data were obtained using Diet Quality Photo Navigation (DQPN®; US Patent #11,328,810 B2) technique via Diet ID™ tool. ANALYSIS: Pearson correlation coefficients (for continuous variables) and Spearman coefficients (for ordinal variables) were used to evaluate associations between nutrient intake data and laboratory data for the full study sample. Two-sided P-values < .05 were considered statistically significant. RESULTS: Both continuous and ordinal measures of diet quality correlated significantly with HDL-C and triglycerides (n = 485; P < .0 01); with hs-CRP (n = 441; P < .001); with HgbA1c (n = 345; P < .01); with fasting insulin (n = 372; P < .001); and with HOMA-IR (n = 319; P < .001). CONCLUSION: Findings affirm that rapid, digital diet quality and composition assessment by pattern recognition rather than recall tracks significantly with key biomarkers of cardiometabolic health.

OBJECTIVE: We aimed to explore the relationship between socio-economic characteristics and sustainable dietary patterns. DESIGN: Dietary data were derived from a web-based FFQ. Diet sustainability was evaluated using a modified Sustainable Diet Index, comprising nutritional, environmental and cultural components (higher scores expressing higher sustainability). The socio-economic position markers were education, household income and occupation status. Multi-adjusted linear and Poisson regression models were used to assess the cross-sectional association of the markers of socio-economic status with a sustainable diet and sustainability subcomponents, respectively. SETTING: France. PARTICIPANTS: 29 119 NutriNet-Santé participants. RESULTS: Individuals with a more sustainable diet had slightly higher diet monetary cost, lower total energy intake and consumed less animal-based foods than their counterparts. Lower education level was associated with lower overall diet sustainability (ßprimary v. postgraduate = -0·62, 95 % CI (-0·72, -0·51)) and nutrition, socio-cultural and environmental subscores. Manual workers and employees had a lower modified Sustainable Diet Index than intermediate professionals (ßmanual workers v. intermediate professionals = -0·43, 95 % CI (-0·52, -0·33) and ßemployees v. intermediate professionals = -0·56, 95 % CI (-0·64, -0·48)). Participants with the lowest v. highest incomes had a higher environmental subscore but a lower socio-cultural subscore, whereas the results were less marked for occupational status. CONCLUSIONS: Overall, our results documented associations between socio-economic status and the level of diet sustainability, arguing for the implementation of appropriate food policies to promote sustainable diets at lower cost.

BACKGROUND AND OBJECTIVES: Congenital heart disease (CHD) is the common congenital malformations in children and cause malnutrition. We determine the association between dietary nutrient intake and nutritional status of children with CHD. METHODS AND STUDY DESIGN: 428 children of age 1-10 years with CHD admitted. The dietary nutrient intake was recorded after 3 days of 24-h recall. The growth and nutritional status of children were evaluated using anthropometric measurements and z-scores. RESULTS: The prevalence of malnutrition was 37.6% in CHD. 57.8%, 12.6%, 43.8%, and 40.6% of children did not meet their requirements for energy, protein, fat, and carbohydrate, respectively. The prevalence of insufficient intake was 88.3% for calcium, 35.9% for magnesium, 21.9% for iron, and 12.5% for zinc. 15%-86% of children did not meet vitamin requirements. 85.2% and 53.9% of children did not meet their requirements for vitamin A and vitamin C. The prevalence of insufficient intake was 39.1% for thiamin, 24.2% for riboflavin, 15.6% for niacin and 28.1% for vitamin E. Compared with the normal nutrition group, malnutrition group had a relatively lower intake of proteins, iron, zinc and vitamin E. CONCLUSIONS: An obvious deficiency of dietary nutrient intake was found among children with CHD, especially CHD with malnutrition. Dietary intake related to the nutritional status of children with CHD. The gap between actual consumption and recommendation indicates a need for improved nutritional counseling and monitoring. Early interventions targeting the dietary intakes of children with CHD may be a benefit for long-term effects associated with nutritional status.

Accurate dietary analysis of energy, nutrient intake, and meal timing in human studies using traditional dietary assessment methods (e.g., food records) is challenging and time-consuming. The widespread use of smartphones, tablets, and nutrition applications (apps) can overcome some of these problems. The objective of this study was to evaluate the validity of an FDDB smartphone app and food database compared with PRODI®-a professional platform for nutritional counselling using the German Nutrient Database. Dietary records were collected from 10 subjects participating in the crossover intermittent fasting trial for 2 weeks at baseline and during the eating timeframe of 8 h (early or late in the course of the day). The FDDB app and database enabled a quicker and less sophisticated analysis of food composition and timing than the PRODI® software. Good agreement between the methods was found for energy and macronutrient intakes, while the FDDB data on most micronutrients and saturated/unsaturated fat intake were unreliable. In contrast to PRODI®, FDDB provided effective assessment of timely compliance, making it a promising tool for chrononutritional studies. Thus, the FDDB app is comparable to the traditional PRODI® dietary assessment method, and can be effectively used in human dietary trials and medical practice for specific goals.

Stacking multiple genes into cotton crop to cop up multiple biotic stresses such as insects and weeds is a promising tool to save crop from losses. Transgenic cotton variety, VH-289, with double Bt and cp4EPSPS genes under the control of 35S promoter was used for the expression analyses and biosafety studies. The transgenic cotton plants were screened through PCR amplification of fragments, 1.7 kb for Cry1Ac, 582 bp for Cry2A and 250 bp for cp4EPSPS; which confirmed the presence of all genes transformed in transgenic cotton. The Cry1Ac + Cry2A and cp4EPSPS proteins were quantified through ELISA in transgenic cotton plants. The Glyphosate assay performed by spraying 1900 mL per acre of glyphosate Roundup further confirmed complete survival of transgenic cotton plants as compared to the non-transgenic cotton plants and all weeds. Similarly, insect infestation data determined that almost 99% insect mortality was observed in controlled field grown transgenic cotton plants as compared to the non-transgenic control plants. Evaluation of effect of temperature and soil nutrients availability on transgene expression in cotton plants was done at two different cotton growing regions, Multan and Lahore, Pakistan and results suggested that despite of higher temperature in Multan field, an increased level of Cry and cp4EPSPS proteins was recorded due to higher soil organic matter availability compared to Lahore field. Before commercialization of any transgenic variety its biosafety study is mandatory so, a 90 days biosafety study of the transgenic cotton plants with 40% transgenic cottonseeds in standard diet showed no harmful effect on wister rat model when studied for liver function, renal function and serum electrolyte.

The COVID-19 pandemic significantly impacted the healthcare system, including dentistry. However, it is not entirely clear whether affected patients' willingness for regular dental visits and preventive behaviors with regards oral hygiene and diet. This is essential to understanding the potential effects of the COVID-19 pandemic on the acceleration of dental issues in the future. It was aimed at checking the level of dental visit avoidance, self-reported oral health needs, and dietary changes. This cross-sectional questionnaire study conducted in Poland (n = 2574; mean age 44.4 ± 15.6; female 56.3%) assessed nutritional habits and dental care changes during the COVID-19 pandemic. As demonstrated, nearly half of the responders (47.1%) avoided regular dental visits, while only 0.5% used online consultations. Fears related to potential cross-contamination in dental offices dropped from 25% to 11.4% and were associated with increased BMI and age (p < 0.05). Sweet snacking/drinking confirmed 19.1%/33.2% subjects. Self-reported oral health care needs (tooth stain, calculus, gingivitis, loss of fillings) were related to frequent snacking and poor oral hygiene (p < 0.05). The study highlights that pandemic periods are covered by eating and drinking changes combined with inadequate hygiene and dental care impose health complaints in the oral cavity. This can magnify both nutritional and interrelated oral health issues, highlighting the need to implement preventive and mitigation measures.

The transition from adolescence to adulthood is a critical period for the development of healthy behaviors. Yet, it is often characterized by unhealthy food choices. Considering the current pandemic scenario, it is also essential to assess the effects of coronavirus disease-19 (COVID-19) on lifestyles and diet, especially among young people. However, the assessment of dietary habits and their determinants is a complex issue that requires innovative approaches and tools, such as those based on the ecological momentary assessment (EMA). Here, we describe the first phases of the "HEALTHY-UNICT" project, which aimed to develop and validate a web-app for the EMA of dietary data among students from the University of Catania, Italy. The pilot study included 138 students (mean age 24 years, SD = 4.2; 75.4% women), who used the web-app for a week before filling out a food frequency questionnaire with validation purposes. Dietary data obtained through the two tools showed moderate correlations, with the lowest value for butter and margarine and the highest for pizza (Spearman's correlation coefficients of 0.202 and 0.699, respectively). According to the cross-classification analysis, the percentage of students classified into the same quartile ranged from 36.9% for vegetable oil to 58.1% for pizza. In line with these findings, the weighted-kappa values ranged from 0.15 for vegetable oil to 0.67 for pizza, and most food categories showed values above 0.4. This web-app showed good usability among students, assessed through a 19-item usability scale. Moreover, the web-app also had the potential to evaluate the effect of the COVID-19 pandemic on students' behaviors and emotions, showing a moderate impact on sedentary activities, level of stress, and depression. These findings, although interesting, might be confirmed by the next phases of the HEALTHY-UNICT project, which aims to characterize lifestyles, dietary habits, and their relationship with anthropometric measures and emotions in a larger sample of students.

Dietary habits, that are formed during childhood and consolidated in adulthood, are known to influence the development of future chronic diseases such as metabolic syndrome or type 2 diabetes. The aim of this review was to evaluate the effectiveness of nutritional interventions carried out in recent years focused on improving the quality of the diet of the child population. A systematic search of the PubMed and Scopus databases was performed from January 2011 until September 2021. A total of 910 articles were identified and screened based on their title, abstract and full text. Finally, 12 articles were included in the current systematic review. Of those, in six studies the intervention was based on the provision of healthy meals and in the other six studies the intervention focused on modifying the school environment. Six of the studies selected included other components in their intervention such as nutritional education sessions, physical activity and/or families. A wide variety of methods were used for diet assessments, from direct method to questionnaires. The results suggest that interventions that modify the school environment or provide different meals or snacks may be effective in improving children's dietary patterns, both in the short and long term. Further research is necessary to evaluate the real effectiveness of strategies with multidisciplinary approach (nutritional sessions, physical activity and family's involvement).

OBJECTIVES: Lifestyle interventions during pregnancy improve maternal and infant outcomes. We aimed to compare the cost-effectiveness of 4 antenatal lifestyle intervention types with standard care. METHODS: A decision tree model was constructed to compare lifestyle intervention effects from a novel meta-analysis. The target population was women with singleton pregnancies and births at more than 20 weeks' gestation. Interventions were categorized as diet, diet with physical activity, physical activity, and mixed (lacking structured diet and, or, physical activity components). The outcome of interest was cost per case prevented (gestational diabetes, hypertensive disorders in pregnancy, cesarean birth) expressed as an incremental cost-effectiveness ratio (ICER) from the Australian public healthcare perspective. Scenario analyses were included for all structured interventions combined and by adding neonatal intensive care unit costs. Costs were estimated from published data and consultations with experts and updated to 2019 values. Discounting was not applied owing to the short time horizon. RESULTS: Physical activity interventions reduced adverse maternal events by 4.2% in the intervention group compared with standard care and could be cost saving. Diet and diet with physical activity interventions reduced events by 3.5% (ICER = A$4882) and 2.9% (ICER = A$2020), respectively. Mixed interventions did not reduce events and were dominated by standard care. In scenario analysis, all structured interventions combined and all interventions when including neonatal intensive care unit costs (except mixed) may be cost saving. Probabilistic sensitivity analysis showed that for physical activity and all structured interventions combined, the probability of being cost saving was 58% and 41%, respectively. CONCLUSIONS: Governments can expect a good return on investment and cost savings when implementing effective lifestyle interventions population-wide.

Adequate nutrition during the complementary feeding period is critical for optimal child growth and development and for promoting long-term educational attainment and economic potential. To prioritize limited public health resources, there is a need for studies that rigorously assess the influence of multicomponent integrated nutrition interventions in children younger than age 2 years in different contexts. This study aimed to describe the rationale and protocol for the Saqmolo' Project using the Standard Protocol Items: Recommendations for Interventional Trials (SPIRIT) guidelines. The Saqmolo' (ie, "egg" in the Mayan language, Kaqchiquel) Project is an individually randomized, partially blinded, controlled comparative effectiveness trial to evaluate the influence of adding delivery of a single whole egg per day to local standard nutrition care (ie, growth monitoring, medical care, deworming medication, multiple micronutrient powders for point-of-use food fortification [chispitas], and individualized complementary and responsive feeding education for caregivers) for 6 months, compared with the local standard nutrition care package alone, on child development, growth, and diet quality measures in rural indigenous Mayan infants aged 6 to 9 months at baseline (N = 1,200). The study is being executed in partnership with the Wuqu' Kawoq/Maya Health Alliance, a primary health care organization located in central Guatemala. Primary outcomes for this study are changes in global development scores, assessed using the Guide for Monitoring Global Development and the Caregiver Reported Child Development Instruments. Secondary outcomes include changes in infant hemoglobin, anthropometric measures (including z scores for weight for age, length for age, weight for length, and head circumference for age), and diet quality as measured using the World Health Organization's infant and young child feeding indicators. The results of the Saqmolo' Project may help to inform public health decision making regarding resource allocation for effective nutrition interventions during the complementary feeding period.

The aim of the study was to assess the diversity of dietary patterns within the elderly, in relation to the region of residence, household structure, and socioeconomic status. The questionnaire was conducted in a group of 427 Polish adults aged 60 and older from June to September 2019. The sample was selected by means of the snowball method in two regions. Principal component analysis (PCA) was used to extract and identify three dietary patterns (factors) from the frequency of eating 32 groups of foods. Logistic regression analysis was used to determine the relationship between the identified dietary patterns (DPs), region, household status, and socioeconomic index (SES). Adherence to the identified DPs, i.e., traditional, prudent, and adverse, was associated with socioeconomic status (SES) and living environment, i.e., living alone, with partner, or with family, while the region did not differentiate them. Less people living with their family were characterized by the frequent consumption of traditional food (the upper tertile of this DP), while more of them often consumed food that was typical for both prudent and adverse DPs (the upper tertiles of these DPs). The presence of a partner when living with family did not differentiate the adherence to DPs. A high SES decreased the chances of adhering to the upper tertiles of the "prudent" and "traditional" DPs, while living with family increased the chances of adhering to both the upper and middle tertiles of the "prudent" DP. Identifying the dietary patterns of the elderly contributes to a better understanding of the food intake of the senior citizens living in different social situations, in order to support public policies and nutritional counseling among this age group.

Under- and over-nutrition co-exist as the double burden of malnutrition that poses a public health concern in countries of the developing regions, including South Africa (SA). Vulnerable groups such as pregnant women and children under five years are the most affected by malnutrition, especially in rural areas. Major contributing factors of malnutrition include food and nutrition insecurity, poverty, and unhealthy lifestyles. The current study aimed to assess the nutritional status, using selected anthropometric indices and dietary intake methods (repeated 24 h recall and food frequency), of four rural communities in KwaZulu-Natal (SA). Purposive sampling generated a sample of 50 households each in three rural areas: Swayimane, Tugela Ferry, and Umbumbulu and 21 households at Fountain Hill Estate. The Estimated Average Requirement cut-point method was used to assess the prevalence of inadequate nutrient intake. Stunting (30.8%; n = 12) and overweight (15.4%; n = 6) were prevalent in children under five years, whilst obesity was highly prevalent among adult females (39.1%; n = 81), especially those aged 16-35 years. There was a high intake of carbohydrates and a low intake of fibre and micronutrients, including vitamin A, thus, confirming the need for a food-based approach to address malnutrition and micronutrient deficiencies, particularly vitamin A deficiency.

OBJECTIVE: This pilot study assessed the effectiveness and acceptability of personalized nutrition intervention for mobile food pantry users. METHODS: The 8-week intervention recruited 25 participants in the control (n = 13) and in the treatment (n = 12) groups (60% obese). Personalized nutrition and health reports were generated based on baseline dietary intake and health status. The treatment group received weekly phone counseling and nutrition education, while the control group was only contacted to ensure compliance. The primary outcomes were 8-week changes in weight and diet quality score, assessed by the Healthy Eating Index. RESULTS: The acceptability of the intervention was assessed by the eligibility rate, recruitment rate (62.5%), and drop-out rate (36%). Following the intervention, there was a significant decrease in weight (mean ± standard deviation, -2.3% ± 2.4%) among all participants (p < 0.05). Diet-quality improved (4.54% in treatment vs. 0.18% in control), but was ultimately non-significant (p = 0.284). CONCLUSIONS AND IMPLICATIONS: A personalized nutrition education intervention in mobile food pantry users may be an acceptable and effective intervention to encourage weight loss through dietary improvements.

Diet influences the health of pregnant women and their children in prenatal, postnatal and adult periods. GC-FID fatty acids profile analysis in maternal serum and a survey of dietary habits were performed in 161 pregnant patients from the II Faculty and Clinic of Obstetrics and Gynaecology of the Medical University of Warsaw. Their diet did not fulfil all nutritional recommendations regarding dietary fat sources. Olive and rapeseed oil were the most popular edible oils. High usage of sunflower oil as well as high consumption of butter were also observed, whereas fish and fish oil intake by pregnant women was low. A chemometric approach for nutritional data, connected with anthropometric, sociodemographic and biochemical parameters regarding mothers and newborns, was conducted for diet and its impact estimation. It revealed four clusters of patients with differing fatty acids profile, which resulted from differences in their dietary habits. Multiparous women to a lesser extent followed dietary recommendations, which resulted in deterioration of fatty acids profile and higher frequency of complications. Observed high usage of sunflower oil is disquieting due to its lower oxidative stability, whereas high butter consumption is beneficial due to conjugated linoleic acids supply. Pregnant women should also be encouraged to introduce fish and fish oil into their diet, as these products are rich sources of long chain polyunsaturated fatty acids (LC PUFA). Multiparous women should be given special medical care by medical providers (physicians, midwifes and dietitians) and growing attention from the government to diminish the risk of possible adverse effects affecting mother and child.
