RESUMO

BACKGROUND: Malnutrition among women of childbearing age is especially prevalent in Asia and sub-Saharan Africa and can be harmful to the fetus during pregnancy. In the most recently available Demographic and Health Survey (DHS), approximately 10% to 20% of pregnant women in India, Pakistan, Mali, and Tanzania were undernourished (body mass index [BMI] <18.5 kg/m2), and according to the Global Burden of Disease (GBD) 2017 study, approximately 20% of babies were born with low birth weight (LBW; <2,500 g) in India, Pakistan, and Mali and 8% in Tanzania. Supplementing pregnant women with micro and macronutrients during the antenatal period can improve birth outcomes. Recently, the World Health Organization (WHO) recommended antenatal multiple micronutrient supplementation (MMS) that includes iron and folic acid (IFA) in the context of rigorous research. Additionally, WHO recommends balanced energy protein (BEP) for undernourished populations. However, few studies have compared the cost-effectiveness of different supplementation regimens. We compared the cost-effectiveness of MMS and BEP with IFA to quantify their benefits in 4 countries with considerable prevalence of maternal undernutrition. METHODS AND FINDINGS: Using nationally representative estimates from the 2017 GBD study, we conducted an individual-based dynamic microsimulation of population cohorts from birth to 2 years of age in India, Pakistan, Mali, and Tanzania. We modeled the effect of maternal nutritional supplementation on infant birth weight, stunting and wasting using effect sizes from Cochrane systematic reviews and published literature. We used a payer's perspective and obtained costs of supplementation per pregnancy from the published literature. We compared disability-adjusted life years (DALYs) and incremental cost-effectiveness ratios (ICERs) in a baseline scenario with existing antenatal IFA coverage with scenarios where 90% of antenatal care (ANC) attendees receive either universal MMS, universal BEP, or MMS + targeted BEP (women with prepregnancy BMI <18.5 kg/m2 receive BEP containing MMS while women with BMI ≥18.5 kg/m2 receive MMS). We obtained 95% uncertainty intervals (UIs) for all outputs to represent parameter and stochastic uncertainty across 100 iterations of model runs. ICERs for all scenarios were lowest in Pakistan and greatest in Tanzania, in line with the baseline trend in prevalence of and attributable burden to LBW. MMS + targeted BEP averts more DALYs than universal MMS alone while remaining cost-effective. ICERs for universal MMS compared to baseline IFA were $52 (95% UI: $28 to $78) for Pakistan, $72 (95% UI: $37 to $118) for Mali, $70 (95% UI: $43 to $104) for India, and $253 (95% UI: $112 to $481) for Tanzania. ICERs for MMS + targeted BEP compared to baseline IFA were $54 (95% UI: $32 to $77) for Pakistan, $73 (95% UI: $40 to $104) for Mali, $83 (95% UI: $58 to $111) for India, and $245 (95% UI: $127 to $405) for Tanzania. Study limitations include generalizing experimental findings from the literature to our populations of interest and using population-level input parameters that may not reflect the heterogeneity of subpopulations. Additionally, our microsimulation fuses multiple sources of data and may be limited by data quality and availability. CONCLUSIONS: In this study, we observed that MMS + targeted BEP averts more DALYs and remains cost-effective compared to universal MMS. As countries consider using MMS in alignment with recent WHO guidelines, offering targeted BEP is a cost-effective strategy that can be considered concurrently to maximize benefits and synergize program implementation.

RESUMO

Micronutrient powder (MNP) can reduce iron deficiency in young children, which has been well established in efficacy trials. However, the cost of different delivery platforms has not been determined. We calculated the cost and cost-efficiency of distributed MNP through community-based mechanisms and in health facilities in a primarily rural district in Uganda. An endline survey (n = 1072) identified reach and adherence. During the 9-month pilot, 37,458 (community platform) and 12,390 (facility platform) packets of MNP were distributed. Each packet consisted of 30 MNP sachets. In 2016, total costs were $277,082 (community platform, $0.24/sachet) and $221,568 (facility platform, $0.59/sachet). The cost per child reached was lower in the community platform ($53.24) than the facility platform ($65.97). The cost per child adhering to a protocol was $58.08 (community platform) and $72.69 (facility platform). The estimated cost of scaling up the community platform pilot to the district level over 3 years to cover approximately 17,890 children was $1.23 million (scale-up integrated into a partner agency program) to $1.62 million (government scale-up scenario). Unlike previous estimates, these included opportunity costs. Community-based MNP delivery costs were greater, yet more cost-efficient per child reached and adhering to protocol than facility-based delivery. However, total costs for untargeted MNP delivery under program settings are potentially prohibitive.

RESUMO

BACKGROUND: When maternal micronutrient intakes and statuses are compromised, reductions in micronutrient concentrations in neonatal stores and human milk may result in suboptimal micronutrient intakes, statuses, and functional outcomes of breastfed infants during the critical first 6-month period. OBJECTIVES: We compared the adequacy of micronutrient intakes and statuses at 2 and/or 5 months and morbidity and growth faltering at 2, 5, and 12 months in a cohort of exclusively breastfed (EBF) and partially breastfed (PBF) infants from low-resource Indonesian households. METHODS: At 2 and 5 months, the breastfeeding status and human milk intake of 212 infants were determined using the deuterium oxide dose-to-mother technique, and intakes were calculated from milk micronutrient concentrations and 3-d weighed food intakes. At 5 months, five infant micronutrient biomarkers, hemoglobin, C-reactive protein, and α-1-acid-glycoprotein were measured. Infant morbidity, weight, and length were measured at 2, 5, and 12 months. Means, medians, or proportions were reported for each group and differences between groups were statistically determined. RESULTS: Median intakes of iron, thiamin, niacin, and vitamin B-12 were higher in PBF than EBF infants at 5 months (all P values < 0.05), but intakes in all infants were below adequate intakes. At 5 months, anemia was <20% in both groups, although fewer PBF versus EBF infants had vitamin B-12 deficiency (11.5% vs. 28.6%, respectively; P = 0.011). The mean ± SD length-for-age z-scores for EBF versus PBF infants at 2 months were 0.7 ± 0.9 versus -0.5 ± 1.1, respectively  (P = 0.158), declining to -1.4 ± 0.9 versus -1.1 ± 1.2, respectively, at 12 months (P = 0.059). Reported morbidity rates were generally low, with no evidence of a difference between infant groups (all P values > 0.126). CONCLUSIONS: Irrespective of exclusive or partial breastfeeding status, micronutrient intakes of infants were low, statuses were compromised, and growth faltering during the critical 6 months period of early infancy was present. The findings highlight the importance of improving maternal nutritional statuses and evaluating their impacts on infant outcomes.

RESUMO

This study aimed to develop a set of mean ± standard deviation (SD) intake values for South African (SA) children for 36 of the 45 food parameters included in the original Dietary Inflammatory Index (DII®) tool. The SA food composition database contains 30 of the 45 food parameters included in the original DII®, and a supplementary database was developed for six of the food parameters not included in the SA database. The SA child mean ± SD intake of macronutrients, micronutrients and select flavonoids was calculated by age in years, using eight data sets from dietary surveys conducted in SA in the last three decades. A total sample of 5412 children was included in the calculation of the mean ± SD. The current study sample was determined to be representative of 1-<10-year-old children in SA, and the plausibility of the mean intake values was confirmed by being in line with age-appropriate recommendations. Furthermore, an increase in energy, macronutrient, and most micronutrient intakes with increase in age was evident. The generated mean ± SD values for SA children can be used for calculation of the inflammatory potential of the dietary intake of SA children in the age range of 1-<10-year-old children.

RESUMO

INTRODUCTION: Introduction: among adolescent gymnasts some concern for body weight has been observed, with diets inadequate in energy and some nutrients in the search for maximum performance. Objective: the aim of this study was to evaluate the dietary-nutritional status, body composition, eating behavior, and perceived body image concerns of female gymnasts at sub-national competition levels. In addition, to study the relationship between the prevalence of the risk of eating disorders and variables such as substance use, irregular menstruation, fatigue, and hours of sleep. Materials and method: a total of 33 female subelite gymnasts participated (age: M = 14.52, SD = 1.85), with age ranging from 11 to 18 years. Anthropometric evaluations (restricted profile) were made, the Eating Attitudes Test (EAT-26) and Body Shape Questionnaire (BSQ) were administered, and the subjects were then interviewed for collecting sociodemographic, socio-sports, health, and food intake data. Results: the results showed that their diet was deficient, among other micro- and macro-nutrients, in water, carbohydrates, proteins, vitamins D and E, fiber, iron and calcium, whereas they ingested an excess of vitamin A and sodium. These athletes had normal weight, high muscle mass values, low fat mass levels, and intermediate somatotype components (balanced endomorph with a tendency to central). Two cases at risk for an eating disorder, and concerns related to perceived body image in a quarter of the sample were identified. Conclusion: the risk of having an eating disorder is related to the consumption of prohibited drugs or addictive substances, irregular menstruation, tiredness, and fewer hours of sleep.


INTRODUCCIÓN: Introducción: entre las gimnastas adolescentes se ha observado cierta preocupación por el peso, con dietas insuficientes en energía y algunos nutrientes en búsqueda del máximo rendimiento. Esta preocupación puede estar relacionada con trastornos de la conducta alimentaria, menstruación irregular, cansancio y descanso insuficiente. Objetivos: evaluar el estado diétético-nutricional, la composición corporal, el comportamiento alimentario y la preocupación por la imagen corporal de las gimnastas de competición. Métodos: estudio observacional y transveral en el que participaron 33 gimnastas femeninas (edad: M = 14,52, DT = 1,85), subélite, de entre 11 y 18 años de edad. Se realizaron valoraciones antropométricas, se les aplicó un test de actitudes alimentarias (EAT-26) y un cuestionario sobre la figura corporal (BSQ), y se las entrevistó, recogiéndose datos sociodemográficos, sociodeportivos, de salud y sobre la ingesta. Resultados: la dieta de las deportistas es principalmente deficitaria en agua, carbohidratos, proteínas, vitaminas D y E, fibra, hierro y calcio, con sobreingesta de vitamina A y sodio. Las deportistas presentan normopeso y valores altos de masa muscular, bajos de masa grasa y medios de los componentes del somatotipo (endomorfo equilibrado con tendencia a central). Se detectaron dos casos de riesgo de trastorno de la conducta alimentaria (TCA) y preocupación por la imagen corporal percibida en un cuarto de la muestra. Conclusiones: el riesgo de padecer un TCA se relaciona con el consumo de fármacos prohibidos o sustancias adictivas, la menstruación irregular, el cansancio y dormir menos horas.

RESUMO

Poor dietary intake during pregnancy remains a significant public health concern, affecting the health of the mother and fetus. This study examines the adequacy of energy, macronutrient, and micronutrient intakes among self-declared lacto-vegetarian and non-vegetarian pregnant women. We analyzed dietary data from 627 pregnant women in Uttar Pradesh, India, using a multiple-pass 24 h diet recall. Compared to non-vegetarians, lacto-vegetarians (~46%) were less likely to report excessive carbohydrate (78% vs. 63%) and inadequate fat intakes (70% vs. 52%). In unadjusted analyses, lacto-vegetarians had a slightly higher mean PA for micronutrients (20% vs. 17%), but these differences were no longer significant after controlling for caste, education, and other demographic characteristics. In both groups, the median intake of 9 out of 11 micronutrients was below the Estimated Average Requirement. In conclusion, the energy and micronutrient intakes were inadequate, and the macronutrient intakes were imbalanced, regardless of stated dietary preferences. Since diets are poor across the board, a range of policies and interventions that address the household food environment, nutrition counseling, behavior change, and supplementation are needed in order to achieve adequate nutrient intake for pregnant women in this population.

RESUMO

BACKGROUND: Malnutrition linked to noncommunicable diseases presents major health problems across Europe. The World Health Organisation encourages countries to conduct national dietary surveys to obtain data to inform public health policies designed to prevent noncommunicable diseases. METHODS: Data on 27334 participants aged 19-64y were harmonised and pooled across national dietary survey datasets from 12 countries across the WHO European Region. Weighted mean nutrient intakes were age-standardised using the Eurostat 2013 European Standard Population. Associations between country-level Gross Domestic Product (GDP) and key nutrients and nutrient densities were investigated using linear regression. The potential mitigating influence of participant-level educational status was explored. FINDINGS: Higher GDP was positively associated with total sugar intake (5·0% energy for each 10% increase in GDP, 95% CI 0·6, 9·3). Scandinavian countries had the highest vitamin D intakes. Participants with higher educational status had better nutritional intakes, particularly within lower GDP countries. A 10% higher GDP was associated with lower total fat intakes (-0·2% energy, 95% CI -0·3, -0·1) and higher daily total folate intakes (14µg, 95% CI 12, 16) in higher educated individuals. INTERPRETATION: Lower income countries and lower education groups had poorer diet, particularly for micronutrients. We demonstrate for the first time that higher educational status appeared to have a mitigating effect on poorer diet in lower income countries. It illustrates the feasibility and value of harmonising national dietary survey data to inform European policy regarding access to healthy diets, particularly in disadvantaged groups. It specifically highlights the need for strong policies supporting nutritional intakes, prioritising lower education groups and lower income countries.

RESUMO

BACKGROUND: Little is known about sex-based dietary differences in middle-income countries, particularly those undergoing the nutrition transition. This study aims at examining sex disparities in energy and macronutrients' intakes, food consumption patterns, and micronutrients' adequacy in Lebanon, while adopting a life course approach. METHODS: Data were derived from a national cross-sectional survey conducted in Lebanon in 2008/2009. The study sample consisted of 3636 subjects: 956 children and adolescents aged 6-19.9 years; 2239 adults aged 20-59.9 years and 441 older adults aged above 60 years. At the households, trained nutritionists conducted face-to-face interviews with participants to complete a sociodemographic questionnaire and one 24-h diet recall. Food items were categorized into 25 food groups. The Nutritionist Pro software was used for the analysis of dietary intake data and the estimation of energy, macronutrients', and micronutrients' intakes. RESULTS: In all age groups, males had significantly higher energy intakes, while females had significantly higher fiber intakes. In addition, in adolescents aged 12-19.9 years, females had higher fat intakes as compared to males (37.02 ± 0.6% vs 35.03 ± 0.61%), and in adults aged 20-59.9 years, females had significantly higher total fat (37.73 ± 0.33% vs 36.45 ± 0.38%) and saturated fat intakes (11.24 ± 0.15% vs 10.45 ± 0.18%). These differences in macronutrient intakes were not observed in younger children nor in older adults. Sex-based differences in food groups' intakes were also observed: men and boys had significantly higher intakes of red and processed meat, bread, fast food, soft drinks, and alcohol, while girls and women had higher intakes of fruits, vegetables, milk, and sweets. In all age groups, females had lower micronutrient intakes compared to males, including calcium, iron, and zinc. CONCLUSIONS: This study identified sex-specific priorities that ought to be tackled by context-specific interventions to promote healthier diets in Lebanon. The fact that sex-based differences in nutrient intakes and food consumption patterns were the most noticeable in the adolescent and adult years, hence women's reproductive years call for concerted efforts to improve nutrition for women and girls as this would lay the foundation not only for their future education, productivity, and economic empowerment, but also for the health of future generations.

RESUMO

We highlight key findings from a recent comprehensive review of social and behavior change communication (SBCC) interventions to improve complementary feeding in low-middle-income countries and discuss 4 large-scale programs as illustrative case studies. Improving dietary diversity was the most commonly targeted practice, and interpersonal communication was the most commonly used platform for the 64 interventions included in the comprehensive review. The number of behavior change techniques used by any one intervention ranged from 2 to 13 (median 6); all provided instruction on how to perform the target behavior(s), followed by the use of a "credible" source to provide the SBCC (n = 46), demonstration of the behavior (n = 35) and providing information about health consequences of the behavior (n = 35). The key factors that contributed to the success of the large-scale programs applying SBCC alone, or in combination with point-of-use fortification or nutrition-sensitive agriculture, included the formation of alliances with key stakeholders, availability of funds, technical support from multiple donors, well-defined theory of change, and streamlined processes for monitoring and implementation. Major limitations included a lack of detailed information on (a) intervention design, (b) behavioral theories or frameworks, (c) implementation processes including adaptations to context, and (d) cost and feasibility.

RESUMO

Large-scale food fortification is an effective, sustainable, and scalable intervention to address vitamin and mineral deficiencies, however, pressing gaps exist globally around ensuring the quality of fortified foods. This paper summarizes the global challenges and gaps faced in monitoring the quality of fortified foods, the guidance produced in response to these challenges, where we are today in terms of effective implementation, and what approaches and opportunities may be usefully applied to enhance the quality of fortified foods moving forward.

RESUMO

BACKGROUND: Food-assisted maternal and child health and nutrition programs are a widely used approach to address undernutrition. Little is known about the effects of these programs' combined household and individual food rations on household and individual food consumption. Tubaramure in Burundi targeted women and children during the first 1000 d of life, and included: 1) food rations (corn-soy blend and micronutrient-fortified vegetable oil); 2) health services strengthening and promotion of their use; and 3) behavior change communication on nutrition, hygiene, and health practices. OBJECTIVES: The objectives were: 1) to assess Tubaramure's impact on household food consumption and food security, maternal dietary diversity, and infant and young child feeding practices; 2) to explore the role of the food rations; and 3) assess 6-8 mo impacts around 8 mo after the end of the program. METHODS: We used a 4-arm cluster-randomized controlled repeated cross-sectional design (11,906 observations). The treatment arms received the same food ration but differed in the ration timing and duration: 1) the first 1000 d; 2) from pregnancy through 17.9 mo of age; or 3) from birth through 23.9 mo of age. RESULTS: Tubaramure significantly (P < 0.05) improved the percentage of food secure households [from 4.5 to 7.3 percentage points (pp)], and increased household energy consumption (from 17% to 20%) and micronutrient consumption. The program had a positive effect on maternal dietary diversity (+0.4 food groups, P < 0.05) and increased the proportion of children aged 6-23.9 mo consuming ≥4 food groups (from 8.0 to 9.6 pp, P < 0.05). The effects on many outcomes were attributable to the food rations. Postprogram effects (P < 0.05) were found on household food security, maternal dietary diversity, and younger sibling's complementary feeding practices. CONCLUSIONS: Programs such as Tubaramure have the potential to improve food security and household and individual energy and micronutrient consumption in severely resource-constrained populations, as seen in rural Burundi. This trial was registered at clinicaltrials.gov as NCT01072279.

RESUMO

BACKGROUND AND AIMS: Paraoxonase 1 (PON1) is considered to play a crucial role as an anti-atherosclerotic factor. The PON1 activity is affected by genetic polymorphisms, environmental factors, age, sex, lifestyle, pharmaceutical drugs, and dietary factors. The aim of this study was to evaluate the association between macro- and micronutrients as well as PON1 concentration and activities in patients with cardiovascular diseases (CVD), cardiovascular risk factors but no CVD (CRF), and in healthy controls (control group). METHODS AND RESULTS: A case-control study was carried out with 356 volunteers from the Mexican Institute of Social Security, Mexico. Clinical parameters, lipid profile, PON1 activities (AREase, LACase, CMPAase and PONase), and PON1 concentration were evaluated. There was a differential intake of macro- and micronutrients among the study groups. The intake of proteins and carbohydrates was higher in the CVD group than in the CFR and control groups (p < 0.05). AREase, LACase, and CMPAase activities and PON1 concentration were lowest in the CVD group. CONCLUSION: LACase and CMPAase activities, as well as PON1 concentration, could be included in the battery of CVD predictive biomarkers in the Mexican population.

RESUMO

During early postnatal development, biomolecules are particularly exposed to the detrimental actions of unneutralized reactive oxygen species. These prooxidant molecules have been claimed to mediate the trade-off between growth and somatic maintenance. Vitamin E is a key exogenous antioxidant that plays an important role in protecting biological membranes against oxidative damage. However, evidence of the effect of vitamin E supplementation during early life on growth and oxidative status in wild populations is equivocal. We tested the effect of supplementing western bluebird nestlings (Sialia mexicana) with vitamin E on growth rate, antioxidant capacity, and oxidative damage to lipids. During the period of accelerated growth (5-8 d), bill growth rate was 21% higher in supplemented nestlings from nests with breeding helpers than in supplemented nestlings from unassisted nests. Vitamin E also boosted tarsus growth rate during the period of slow growth (11-18 d), and this effect was independent of the presence of breeding helpers. Differences in body size and mass, oxidative damage to lipids, and antioxidant capacity were not evident between supplemented and control nestlings at 18 d. Therefore, we conclude that vitamin E promoted faster bill and tarsus growth, but this transient effect disappeared as soon as the supplementation ceased. Our experimental study also supports the idea that tocopherols are rapidly metabolized, since we failed to detect any evident increase of vitamin E in supplemented nestlings at age 18 d. These results provide partial support for the hypothesis that growth rate is constrained by its costs in terms of increased susceptibility to oxidative stress.

RESUMO

BACKGROUND: Despite positive nutrition impacts, the prevalence of malnutrition among beneficiaries of Mexico's conditional cash transfer (CCT) program remains high. Greater nutrition impact may have been constrained by the type of nutritional supplements provided. OBJECTIVE: The objective of this study was to inform a potential modification to the supplements distributed to pregnant and lactating women and children. METHODS: Impact was assessed using 2 cluster-randomized trials (pregnant women, children) run simultaneously. Communities (n = 54) were randomly assigned to the fortified foods provided by the program (Nutrivida women, Nutrisano children) or alternatives: tablets (women), syrup (children), or micronutrient powders for women (MNP-W) and children (MNP-C). Each supplement for women/children contained the same micronutrients based on the formulations of Nutrivida and Nutrisano, respectively. Pregnant women (aged >18 y) were recruited before 25 weeks of gestation and followed to 3 mo postpartum. Children aged 6-12 mo were recruited and followed to age 24 mo. Primary outcomes were anemia for women and length growth for children. Statistical analyses appropriate for cluster-randomized designs were used, and structural equation modeling to estimate dose-response effects. Supplement costs per beneficiary (daily dose for 18 mo) were estimated for production and distribution. RESULTS: There was no significant difference in change of anemia prevalence between supplement groups in women, or in length growth between groups in children. One daily dose of any supplement was associated with 0.8 cm greater length growth. From baseline to age 24 mo, the prevalence of anemia in the Nutrisano, syrup, and MNP-C groups decreased by 36.7, 40.8, and 37.9 percentage points, respectively (within-group, P < 0.05; between groups, P > 0.05). Costs per beneficiary ranged from $12.1 (MNP-C) to $94.8 (Nutrivida). CONCLUSIONS: The CCT program could distribute alternative supplements at lower cost per beneficiary without compromising potential for impact. Acceptance among beneficiaries should also be considered in choice of alternatives. This trial was registered at www.clinicaltrials.gov as NCT00531674.

RESUMO

BACKGROUND: Mexico's Prospera-Oportunidades-Progresa Conditional Cash Transfer Program (CCT-POP) included the distribution of fortified food supplements (FFS) for pregnant and lactating women and young children. Rigorous evaluations showed significant impacts on nutrition outcomes but also substantial gaps in addressing nutrition problems. OBJECTIVES: To highlight the program design-related and implementation-related gaps and challenges that motivated further research and the eventual design and roll-out of a modified nutrition component for CCT-POP. METHODS: We used a program impact pathway approach to highlight the extent and quality of implementation of CCT-POP, and its impact on nutrition outcomes. We drew on previously published and new primary data, organized into 3 sources: impact evaluations, studies to inform reformulation of the FFS, and a longitudinal follow-up study using qualitative and quantitative methods to document FFS use and the dietary intake of women and children. RESULTS: Despite positive impacts, a high prevalence of malnutrition persisted in the population. Coverage and use of health services improved, but quality of care was lacking. Consumption of FFS among lactating women was irregular. Micronutrient intake improved among children who consumed FFS, but the pattern of use limited frequency and quantity consumed. Substantial diversity in the prevalence of undernutrition was documented, as was an increased risk of overweight and obesity among women. CONCLUSIONS: Three key design and implementation challenges were identified. FFS, although well accepted for children, had limited potential to substantially modify the quality of children's diets because of the pattern of use in the home. The communications strategy was ineffective and ill-suited to its objective of motivating FFS use. Finally, the program with its common design across all regions of Mexico was not well adapted to the special needs of some subgroups, particularly indigenous populations. The studies reviewed in this paper motivated additional research and the eventual redesign of the nutrition component.

RESUMO

Calcium and vitamin D are essential micronutrients, whose deficiency adversely affects not only bone health, but also the functioning of the whole organism. The aim of this study was to explore the level of calcium and vitamin D intake in the adult population of the Tyumen region, in order to optimize the nutritional program. Material and methods. The study included 440 people living in Tyumen and Tyumen region. Inclusion in the study was conducted on the principle of random sampling using a random number program. The questionnaire was used to estimate the consumption of calcium and vitamin D with food. Serum level of 25(OH)D was determined in all participants of the study, the analysis was carried out by ELISA using Sunrise Euroimmin 25-OH Vitamin D ELISA test systems. Results and discussion. The results of our own data led to the conclusion that there were a lack of consumption of foods rich in vitamin D among all ages and inadequate intake of calcium, especially in the older age groups. Approximately half of the respondents rarely ate sea fish, which was interrelated with plasma levels of 25(OH)D - vitamin D deficiency was detected in 70.7%, and its insufficiency was recorded in 22.0% of those examined. Only 45.5% of respondents consumed dairy products daily, while in general there was deficit of calcium intake in all age groups compared with the average age norm. Conclusion. Adequate compensation of chronic calcium and vitamin D deficiency, which is widespread in both the Russian Federation and the Tyumen region, is an extremely important preventive direction of modern medicine.

RESUMO

The Eastern Mediterranean Regions and Europe and Central Asia Regions are facing an epidemiological and nutrition transition, especially among vulnerable groups including mothers, children and adolescents. This has led to a double burden of malnutrition (DBM). Poor infant and young child feeding (IYCF), poor dietary diversity, excessive consumption of energy dense unhealthy foods, a growing obesogenic environment for children, including aggressive marketing of unhealthy foods for children, and reduced physical activity are among the main causes. In addition, several countries in the region lack the nutrition governance capacity to respond effectively to the DBM. This article reviews the context and provides a set of conclusions in which countries are called to reduce the marketing of unhealthy foods for children, enforce the fortification of staple foods with micronutrients to reduce micronutrient deficiencies and improve IYCF, including breastfeeding in the region. Also, the call is strong for cross-border multi-sectoral efforts to address the DBM in these regions.

RESUMO

BACKGROUND: The double burden of malnutrition in Asia and the Pacific is driving a renewed focus on maternal malnutrition. SUMMARY: Though adverse consequences of maternal malnutrition have been long recognized, there is slow progress in addressing nutritional problems of women/adolescent girls. Coverage and quality of current maternal nutrition interventions, mostly delivered through antenatal care programmes vary across countries, and are often sub-optimum. Further, despite a marked increase in overweight and obesity in women of reproductive age, at present, most programmes are focused on under-nutrition and micronutrient deficiencies. Key Messages: The recent antenatal care recommendations released by World Health Organization provide a benchmark for countries to evaluate their programmes and identify gaps and challenges to improving maternal nutrition. Asian and Pacific countries need to address all forms of maternal malnutrition. For countries that historically focused on maternal under-nutrition, expanding their programmes to incorporate interventions to address overweight and obesity will be challenging. Innovative methods for nutrition counselling, both in terms of content and using novel channels of communication, are needed. Protocols and guidance on managing excessive weight gain as well as determining appropriate pregnancy weight gains are needed, while managing micronutrient deficiencies, particularly in settings where inherited disorders of red blood cells exist.

RESUMO

BACKGROUND: Hunger, food insecurity, stunting, anemia, overweight, and noncommunicable diseases (NCDs) may coexist in the same person, household, and community in Latin America and the Caribbean (LAC). The double burden of malnutrition (DBM) is an important cause of disability and premature death, which could be addressed with comprehensive policies such as the Plan of Action for the Prevention of Obesity in Children and Adolescents. This paper summarizes the main policies and actions aimed to prevent undernutrition and obesity. SUMMARY: Several countries are implementing the Plan of Action, Caribbean Public Health Agency is actively supporting Ministries of Health, Education, and Sport to develop school nutrition policies and strategies to create health-promoting environments at school and in their surrounding communities. Chile is implementing the comprehensive child protection system "Chile Crece Contigo" that integrates health, social development, and educational activities to optimize growth and childhood cognitive-motor development. Brazil is implementing policies and plans to commit to international targets regarding food and nutrition security, NCDs and their risk factors. Key Messages: The DBM exists in the Americas and contributes to disability and premature death. The Region is making progress implementing policies and actions addressing the DBM. However, stronger political will and leadership are needed to enact legislation and policies that create and support enabling -environments.

RESUMO

In South Asia, maternal and child undernutrition is common with consequences for short- and long-term health. In the MINIMat trial (Maternal and Infant Nutrition Interventions in Matlab) in Bangladesh 4436 pregnant women were allocated to early or later start of food supplements and different micronutrient alternatives. Children of mothers who received food supplementation from week 9 combined with multiple micronutrients showed a halved infant mortality rate. The early initiation of prenatal food supplementation reduced the risk of stunting up to five years and was associated with more favourable metabolic markers. The MINIMat study is run by icddr,b in Bangladesh and Uppsala University in collaboration with seven other universities. Twenty Ph.D. students have so far defended their theses and more than 100 scientific papers have been published.
