Double burden of malnutrition and its socio-demographic determinants among children and adolescents in Malaysia: National Health And Morbidity Survey 2019

IntroductionMalaysia faces the threat of a double burden of malnutrition where undernutrition and overweight (including obesity) coexist in the same population. This study aimed to determine the anthropometric assessment among children and adolescents aged 5 to 17 years and its association with socio-demographic factors.MethodsData were extracted from the National Health and Morbidity Survey conducted in 2019. This cross-sectional survey applied a two-stage stratified sampling design. Socio-demographic characteristics were obtained. Weight and height were measured, age- and sex-specific standard scores for height and BMI were calculated to establish individual’s anthropometric assessment. Having either stunting or thinness was considered undernutrition, while being overweight (including obesity) was considered overnutrition. If someone had undernutrition and/or overnutrition, they were classified as having malnutrition. The prevalence was determined using complex sampling analysis, while the association was assessed through logistic regression. The analysis included a total of 3,185 respondents.ResultsThe prevalence of stunting, thinness, overweight and obesity among the respondents aged 5 to 17 years was 12.7%, 10.0%, 15.0% and 14.8%, respectively. The overall prevalence of malnutrition was 48.3%. Respondents residing in rural had 1.35 times more likelihood of experiencing undernutrition [AOR = 1.35, 95% CI (1.04, 1.77)] compared to their urban counterparts. Boys exhibited a greater likelihood of being overweight and obese than girls [AOR = 1.40, 95% CI (1.13, 1.73)]. Respondents aged 10 to 14 years were 1.37 times more likely to be overnutrition than those aged 5 to 9 years old [AOR = 1.37, 95% CI (1.09, 1.73)].ConclusionThere is growing evidence of the increasing prevalence of coexistence of undernutrition along with overweight and obesity among children and adolescents in Malaysia. Moving forward, greater initiatives and efforts are required to formulate strategies for planning and implementing programs and policies to expedite progress in improving nutrition.

The double burden of malnutrition in individuals: Identifying key challenges and re-thinking research focus.

The 'double burden of malnutrition' is a global health challenge that increasingly affects populations in both low- and middle-income countries (LMICs). This phenomenon refers to the coexistence of undernutrition and overweight or obesity, as well as other diet-related non-communicable diseases, in the same population, household or even individual. While noteworthy progress has been made in reducing undernutrition in some parts of the world, in many of these areas, the prevalence of overweight and obesity is increasing, particularly in urban areas, resulting in greater numbers of people who were undernourished in childhood and have overweight or obesity in adulthood. This creates a complex and challenging situation for research experts and policymakers who must simultaneously address the public health burdens of undernutrition and overweight/obesity. This review identifies key challenges and limitations in the current research on the double burden of malnutrition in individuals, including the need for a more comprehensive and nuanced understanding of the drivers of malnutrition, the importance of context-specific interventions and the need for greater attention to the food environment and food systems. We advocate for the re-evaluation of research strategies and focus, with a greater emphasis on multidisciplinary and systems approaches and greater attention to the synergistic relationship between the biological, environmental, commercial and socio-economic determinants of malnutrition. Addressing these key challenges can enable us to better comprehend and tackle the multifaceted and dynamic issues of the double burden of malnutrition, particularly in individuals and work towards more effective and sustainable solutions.

Assessing the impact of a personalised application-based nutrition intervention on carbohydrate intake in rural Benin

BackgroundThis study aims to assess the effect of a personalised nutrition intervention on nutrient intake in rural Benin as a tool to tackle the double burden of malnutrition. The personalised recommender system uses information from the eating behaviour of all household members combined to provide tailored advice on adjusting the consumption of up to three food items to tackle malnutrition and obesity in the household. Many developing countries nowadays experience the double burden of malnutrition, the coexistence of undernutrition alongside overweight and obesity, as well as other related non-communicable diseases. Personalised nutrition was very effective in European studies in improving nutrition and tackling obesity, which is why this study aims to translate personalised nutrition to a developing country context.ResultsA study was conducted in rural areas of Benin where 720 households were randomly selected. Due to high attrition, we used propensity score matching and looked into average treatment effects. We found that the recommendation to eat less carbohydrates resulted in a reduction in carbohydrate consumption with a significant effect for both the average treatment effect (ATE) of the whole population as well as the average treatment effect of the treated (ATET). We found that households that received the treatment to consume less food items with a high carbohydrate intake have followed this advice and have consumed on average lower levels of carbohydrates than their control counterparts.ConclusionsRising obesity is a worldwide problem that poses a severe challenge for policymakers. Especially in developing countries the change from too little, to too much is seamless. For the increasing obese population, the recommender system could be a useful tool. The idea of personalised nutrition has the potential to be one of the necessary steps in the ongoing battle against obesity and unhealthy diets. The personalised application-based recommender system used in this study has the ability to be a strong and effective tool for policymakers in the ongoing battle of food security vs. obesity in Benin and other countries. We propose that future research focuses more on personalised nutrition in the context of a developing country.

Mapping food system drivers of the double burden of malnutrition using community-based system dynamics: a case study in Peru

BackgroundPeru is facing a double burden of malnutrition (DBM), characterized by the co-existence of undernutrition and overnutrition. Double-duty actions that concurrently target common drivers of undernutrition and overnutrition, while ensuring no unintended side effects, are recommended to effectively address the DBM. To understand these complex common mechanisms and design context-specific double-duty actions, there is a need for participatory systems approaches. This paper provides a case study of applying a community-based system dynamics approach to capture stakeholder perspectives of food system drivers of the DBM in two regions in Peru.MethodsWe implemented a multi-stage community-based system dynamics approach, which included processes for research capacity building for systems approaches, and the designing, piloting, and implementation of stakeholder workshops. A total of 36 stakeholders, representing diverse perspectives, participated in five group model building workshops. Stakeholder views are presented in a causal loop diagram that showcases the feedback mechanisms between key food system drivers of overweight and stunting in Peru.ResultsThe causal loop diagram highlights that prioritization of undernutrition over overnutrition in the policymaking process, due to Peru’s historically high levels of undernutrition, may undermine action against the DBM. It also describes potential mechanisms of unintended impacts of undernutrition policies on the DBM in Peru, including impacts related to within-family distribution and quality of food provided through food assistance programs, and unintended impacts due to regional dynamics.ConclusionsThis paper highlights the importance of a participatory approach to understand local needs and priorities when recommending double-duty actions in Peru and shares practical methodological guidance on applying participatory systems approaches in public health.

Pediatric Nutritional Assessment

Background: Pediatric nutrition plays a vital role in the growth and development of children. It not only meets the daily nutritional needs of healthy children but also supports their normal growth. In contrast, for unhealthy children, it aims to prevent growth delays and developmental issues, especially in cognitive functions. The situation in Indonesia presents a unique challenge with the coexistence of undernutrition and overnutrition, both having significant short-term and long-term health impacts. Discussion: In the realm of pediatric nutrition, malnutrition manifests in various forms. Nutritional deficiencies such as wasting, stunting, and being underweight arise from inadequate dietary intake. Additionally, there are concerns about micronutrient malnutrition, which includes both deficiencies and excesses of vital nutrients. Overnutrition, leading to obesity and associated chronic diseases, is also a significant problem. The approach to pediatric nutritional care is multi-faceted, involving the assessment of nutritional status, determination of individual caloric needs, and selecting the appropriate method for nutrition delivery, whether it be oral, enteral, or parenteral. Monitoring and evaluating the effectiveness of these interventions is a critical ongoing process. An important aspect of preventive care includes educating parents about proper feeding techniques, such as establishing regular meal times and understanding the child's hunger and satiety signals, to avoid feeding difficulties. For cases like Failure to Thrive (FTT), where children do not meet standard growth metrics, careful management is necessary to ensure adequate nutrition and to prevent complications like refeeding syndrome. Conclusion: Effective pediatric nutrition requires a holistic and personalized approach. It is crucial in addressing the dual burden of undernutrition and overnutrition in Indonesia. By implementing proper nutritional care and structured feeding practices, children's health outcomes can be significantly improved, supporting their growth and developmental processes.

Machine learning algorithms for prediction of double burden of malnutrition among Tunisian adults

Abstract Background Malnutrition, referring to both nutritional deficits and excess adiposity (EA), currently affects one third of the world population. In Tunisia, nutritional deficits are still major challenges in a context of epidemiological and nutritional transition. The objectives of our study were to identify the potential risk factors of DBM and propose a better machine learning (ML) based model for predicting DBM among Tunisian adults. Methods About 7963 respondents aged 20 years and over were taken from Tunisian Health Examination Survey (THES), a cross-sectional national household survey undertaken in 2016. DBM was defined as the association of EA and anemia. EA was defined as a waist-to-height ratio ≥0.6 and /or overweight: BMI ≥25kg/m2. Anemia was defined as hemoglobin (Hb)<13g/L in men and Hb < 12g/L in women. The potential risk factors for malnutrition were extracted using logistic regression (LR). Five ML algorithms including Naïve Bayes, support vector machine (SVM), artificial neural network (ANN), AdaBoost and random forest (RF) were employed for predicting DBM and their performance was evaluated using accuracy, precision, recall, and area under the curve (AUC). Results LR illustrated that age, sex, region, wealth index, educational level and marital status were identified as potential risk factors for DBM. AdaBoost had the highest accuracy (89.8%), followed by SVM (89.6%). Naïve Bayes had the highest Recall (98.1%) and the most performant AUC (91.4%), while RF had the highest Precision (70.8%). The ANN had an accuracy of 89%, a precision of 70.4%, a recall of 78.7% and an AUC of 0.851. Conclusions The study demonstrated the efficacy of ML algorithms in predicting DBM in Tunisian adults. AdaBoost and SVM showed the highest accuracy, and could be utilized as an early detection tool to manage DBM and alleviate the burden on the healthcare system. However, larger and more diverse datasets are needed for further validation. Key messages • Double burden of malnutrition, defined as the coexistence of undernutrition and overnutrition, is a significant issue globally and a major challenge in Tunisia. • Machine learning algorithms, particularly AdaBoost and SVM, can be effective tools for predicting and managing double burden of malnutrition in Tunisian adults.

Urban-rural disparity in body mass index: is dietary knowledge a mechanism? Evidence from the China Health and Nutrition Survey 2004-2015.

The co-existence of undernutrition and overweight/obesity has been recognised as a severe challenge in China, with substantial urban-rural disparity. We evaluated short- and long-term associations of urban-rural locality on body mass index (BMI) in Chinese adults overall and stratified by sex, focusing on whether dietary knowledge plays a mediating role. We used cross-sectional and longitudinal study designs with structural equation modelling based on the 2004 (T1) and 2015 (T2) waves of the China Health and Nutrition Survey. We adjusted the models for covariates and performed sensitivity analyses. We cross-sectionally analysed 8932 (53.1% women) and 11 216 adults (54.3% women) at T1 and T2, respectively, and longitudinally investigated 4073 adults (55.6% women) in both T1 and T2. The estimated average dietary knowledge and mean BMI increased from T1 to T2. At each time point, we found significant indications of direct (e.g. urban-rural locality to BMI, urban-rural locality to dietary knowledge, and dietary knowledge to BMI) and indirect associations (e.g. urban-rural locality to dietary knowledge to BMI) overall and for men and women (except that urban-rural locality to BMI) separately. The long-term association between urban-rural locality and BMI attenuated over time and was not mediated by dietary knowledge change alone. Nevertheless, dietary knowledge interacted with BMI, which acted as a pathway from urban-rural locality to BMI in the long term. Urban-rural disparity in BMI persists in Chinese adults and is mediated by dietary knowledge. Policy and educational efforts to improve dietary knowledge among rural people may reduce China's urban-rural disparity in BMI.

Nutrition policy reforms to address the double burden of malnutrition in Zambia: A prospective policy analysis.

The evolution of nutrition patterns in Zambia has resulted in the coexistence of undernutrition and overnutrition in the same population, the double burden of malnutrition. While Zambia has strong policies addressing undernutrition and stunting, these do not adequately address food environment drivers of the double burden of malnutrition and the adolescent age group, hence the need for nutrition policy reforms. We conducted a theory-based qualitative prospective policy analysis involving in-depth interviews with nutrition policy stakeholders and policy documents review to examine the feasibility of introducing nutrition policy options that address the double burden of malnutrition among adolescents to identify barriers and facilitators to such policy reforms. Using the multiple streams theory, we categorized the barriers and facilitators to prospective policy reforms into those related to the problem, policy solutions, and politics stream. Using a life course approach in nutrition programming could facilitate policy reforms as adolescence is one of the critical invention points in a person's lifecycle. Another key facilitator of policy reform was the availability of institutional infrastructure that could be leveraged to deliver adolescent-focused policies. However, the lack of evidence on the burden and long-term impacts of adolescent nutrition problems, the food industry's strong influence over governments' policy agenda setting, and the lack of public awareness to demand better nutrition were perceived as critical barriers to policy reforms. In addition, the use of the individual responsibility framing for nutrition problems was dominant among stakeholders. As a result, stakeholders did not perceive legislative nutrition policy options that effectively address food environment drivers of the double burden of malnutrition to be feasible for the Zambian context. Policy entrepreneurs are required to broker policy reforms that will get legislative policy options on the government's agenda as they can help raise public support and re-engineer the framing of nutrition problems and their solutions in Zambia.

Unravelling the Impact of Food Insecurity on the Prevalence of Double Burden of Malnutrition among Children of Pakistan

Food insecurity is a major cause of double burden of malnutrition among children in developing world. Despite being self-sufficient, Pakistan contains 60% of food insecure population. Moreover, about half of under-five children are stunted and one-tenth are overweight. The coexistence of undernutrition and over nutrition among under-five children is not well investigated in the same household. This study unravels the impact of food insecurity on the prevalence of double burden of malnutrition among under-five children by employing 2018 Pakistan Demographic Health Survey data and hierarchical mixed effect logistic regression. A sample of 3,625 6-29 months old children was included. The results state that child food insecurity increases the risk of double burden (OR: 1.49, CI: 1.03-2.16) after adjusting for household and community level socioeconomic and demographic factors. Food security and nutrition programs should be targeted to prevent early childhood double burden of child malnutrition to avoid future productivity losses.

Lived Experience and Perceptions of Adolescents on Prevention, Causes and Consequences of Double Burden of Malnutrition in Debre Berhan City, Ethiopia: A Qualitative Study.

The coexistence of undernutrition, overweight, and obesity within the same households and populations is recognized as the Double Burden of Malnutrition (DBM). A paradigm shift thinking is needed to mitigate its impact. School adolescents are the most vulnerable groups to DBM. However, lived experiences and perceptions on prevention, causes, and consequences of DBM were not well studied. Therefore, this study aims to explore the lived experiences and perceptions of adolescents about the prevention, causes, and consequences of DBM in Ethiopia. A qualitative research method using phenomenology design was conducted among 20 purposively selected participants from private and government schools from June 3 to July 10, 2022. The further sampling process was guided by a saturation of ideas. In-depth and key informant interviews were conducted to collect the data. The most recent version of Open code 4.03 was utilized to generate meaningful codes, subthemes, and themes. The results were displayed using thematic analysis and respondents' well-spoken verbatims. The study explored the perceptions of adolescents on the causes, prevention, and consequences of DBM. The main causes of DBM identified were poor dietary and drinking habits, poor knowledge and attitude about nutrition, low financial income, unemployment, food insecurity, poor feeding culture, physical inactivity, poor food management, educational and school-related issues, national-related issues, frequent use of ultra-processed foods, and frequent out of home eating. The majority of students were not aware of how DBM will affect their health and academic performance over the long run. The findings showed that despite school adolescents' variations in knowledge, lived experience, attitude, and perceptions, most of them have a poor understanding of the causes, consequences, and prevention mechanisms of the double burden of malnutrition. The results suggest the need for instituting double-duty interventions that have a double impact on the prevention of DBM.

The Triple Burden of Malnutrition in the Era of Globalization.

The term "triple burden of malnutrition" refers to the coexistence of undernutrition (stunting and wasting), micronutrient deficiencies (often termed hidden hunger), and overnutrition (overweight and obesity). The three elements of the triple burden of malnutrition can be found simultaneously within many low-income populations and even within single families. There are common underlying causes to each element of the triple burden of malnutrition. In broad terms, these are as follows: poverty - a lack of access to the most nourishing foods; poor dietary choices - a lack of knowledge about what constitutes the most nourishing foods and a healthy diet; and food supply chain - production and marketing of cheap, low-quality foods. It can be argued that the underlying influence of these distal factors is channeled through a single proximal cause - namely a low nutrient density of foods.

Individual and contextual factors associated with childhood malnutrition: a multilevel analysis of the double burden of childhood malnutrition in 27 countries

BackgroundMalnutrition is a key global health challenge and a major contributor to childhood morbidity and mortality. In recent times, the contrasting coexistence of undernutrition including micronutrient deficiencies and overweight/obesity called double burden of malnutrition has been noted at individual, household or population level and/or at different times in life. The objective of this study was to examine individual, neighborhood and country level factors that are associated with the double burden of childhood malnutrition.MethodsWe conducted multivariable multilevel logistic regression analyses on the most recent demographic and health datasets from surveys conducted between 2015 and 2020 in low- and middle-income countries. We analyzed data of 138,782 children (level 1) living in 13,788 communities (level 2) from 27 countries (level 3).ResultsThe results of our analysis show variation in childhood malnutrition across the 27 countries from as low as 6.5% in Burundi to as high as 29.5% in Timor Leste. After adjusting for all level factors, we found that those who were wasted/overweight tended to have had an episode of diarrhea or fever in the last two weeks preceding the survey, were part of a multiple birth, were being breastfed at the time of the survey and born to mothers with more than one under 5-child resident in neighborhoods with high illiteracy and unemployment rates. The intra-neighbourhood and intra-country correlation coefficients were estimated using the intercept component variance; 44.3% and 21.0% of variance in odds of double burden of childhood malnutrition are consequent upon neighborhood and country level factors respectively.ConclusionsEvidence of geographical clustering in childhood malnutrition at community and country levels was found in our study with variability due to neighborhood level factors twice that of country level factors. Therefore, strategies in tackling the double burden of malnutrition must consider these shared drivers, contextual barriers and geographical clustering effects.

Addressing the Double Burden of Malnutrition using the Life Course Perspective

The double burden of malnutrition refers to the coexistence of undernutrition which is typically characterised by stunting and wasting, alongside overnutrition at all levels of the population. The objective of this article is to review the current issues in addressing the double burden of malnutrition using the life course approach. Studies addressing life course approach in DBM were identified through PubMed & EMBASE databases. Relevant studies were critically appraised. The challenges, opportunities and way forward in addressing DBM through the life course concept were discussed. The review showed that the DBM dilemma could be addressed via a holistic perspective through a life course concept as nutrition plays an important role in influencing health from pre-conception to old age. The life course concept proposes that environmental exposures, including biological, physical, social, and behavioral factors, including life experiences, throughout life, influence health outcomes in current generations and their offspring.

Trend of Ultraprocessed Product Intake Is Associated with the Double Burden of Malnutrition in Mexican Children and Adolescents.

Background: Ultraprocessed products (UPPs) have been associated with unfavorable health outcomes; however, until now, they have not been associated with the coexistence of undernutrition and overnutrition, known as the double burden of malnutrition (DBM) at the individual level. Methods: Cross-sectional analyses were performed on data collected from children and adolescents participating in the 2006 and 2016 Mexican National Health and Nutrition Surveys. The food and beverages reported in the food frequency questionnaire (SFFQ) were classified as UPPs as defined by the NOVA classification system. Associations of UPPs with anemia, excess weight, and the DBM were estimated with logistic regression models. A pseudo-panel was generated using the cohorts of children born from 1997 to 2001 to estimate the effect of the UPPs on anemia, excess weight, and the DBM. Results: The consumption of UPPs (% energy) was higher in 2016 (children 30.1% and adolescents 28.3%) than in 2006 (children 27.3% and adolescents 23.0%) in both age-groups. The higher contribution of UPPs was positively associated with excess weight and the DBM in children’s lower tertile of socioeconomic status (SES) and the DBM in higher tertile of SES in adolescents. The pseudo-panel analysis shows the positive association between UPPs and DBM in lower SES. Conclusions: These results provide evidence of the association between the consumption of UPPs and the DBM and excess weight in children and adolescents.

Double burden of malnutrition in Nepal: A trend analysis of protein-energy malnutrition and High Body Mass Index using the data from Global Burden of Disease 2010-2019.

The co-existence of undernutrition and overnutrition is a global public health threat. We aim to report the burden of both nutritional deficiency (Protein-Energy Malnutrition) and overweight (high Body Mass Index) in Nepal over a decade (2010-2019) and observe the changes through trend charts. We did a secondary data analysis using the Institute for Health Metrics and Evaluation (IHME)'s Global Burden of Disease (GBD) database to download age-standardized data on Protein Energy Malnutrition (PEM) and high Body Mass Index (BMI). We presented the trend of death, Disability Adjusted Life Years (DALYs), Years of Life Lost (YLL), and Years Lost due to Disability (YLD) of PEM and high BMI in Nepal from 2010 to 2019 and also compared data for 2019 among South Asian countries. Between 2010 and 2019, in Nepal, the Disability Adjusted Life Years (DALYs) due to PEM were declining while high BMI was in increasing trend. Sex-specific trends revealed that females had higher DALYs for PEM than males. In contrast, males had higher DALYs for high BMI than females. In 2019, Nepal had the highest death rate for PEM (5.22 per 100,000 populations) than any other South Asian country. The burden of PEM in terms of DALY was higher in under-five children (912 per 100,000 populations) and elderly above 80 years old (808.9 per 100,000 populations), while the population aged 65-69 years had the highest burden of high BMI (5893 per 100,000 populations). In the last decade, the DALYs for risk factors contributing to PEM such as child growth failure (stunting and wasting), unsafe water, sanitation and handwashing, and sub-optimal breastfeeding have declined in Nepal. On the contrary, the DALYs for risk factors contributing to high BMI, such as a diet high in sugar-sweetened beverages, a diet high in trans fatty acid, and low physical activity, have increased. This could be a possible explanation for the increasing trend of high BMI and decreasing trend of PEM. Rapidly growing prevalence of high BMI and the persistent existence of undernutrition indicate the double burden of malnutrition in Nepal. Public health initiatives should be planned to address this problem.

Challenges and perspectives of the double burden of malnutrition in Latin America

Nutrition is a key factor in the development of non-communicable chronic diseases (NCCDs), especially cardiovascular diseases (CVD) and their risk factors. The “double burden of malnutrition” (DBM) is the coexistence of undernutrition and overnutrition in the same population across the life-course. In Latin America, the transition from a predominantly underweight to an overweight and obese population has increased more rapidly than in other regions in the world.Undernutrition and the micronutrient deficiencies particularly iron, zinc, and vitamins A and D, present high heterogeneity in Latin American countries, and are currently considered important public health problems. In this region, NCCDs account for 50% of the disability-adjusted life-years, led by CVD. The most prevalent cardiovascular risk factors are overweight, obesity, hypertension, dyslipidemia and type 2 diabetes mellitus. Because of the cost of treatment and the potential years of life lost due to premature death, CVD is known to affect the poorest segments of the population, affecting communities, and governments. More than 80% of CVD deaths occur in low- and middle-income countries. The persistence of damage in some cells due to undernutrition may explain certain findings regarding the increase in NCCD. These aspects together with epigenetic changes have highlighted the importance of a lifelong approach to nutritional policy development.Reducing DBM requires major societal interventions in public health and nutrition to achieve holistic change that can be sustained over the long term and spread throughout the global food system. The implementation of effective state policies of double impact actions should influence both sides of the burden and be considered an urgent priority, considering country-specific inequalities and socio-demographic differences in the Latin American region, using diverse and multidisciplinary strategies.

Significant Nutritional Gaps in Tibetan Adults Living in Agricultural Counties Along Yarlung Zangbo River.

BackgroundDietary intake and nutritional assessing data from a representative sample of adult population living in an agricultural zone on Tibet Plateau are still lacking nowadays. This study aimed to assess the daily dietary intakes and respective food sources in 552 local residents (≥ 18 years old, 277 men and 275 women) living in 14 agricultural counties along the Yarlung Zangbo River on Tibet Plateau.MethodsFood consumption data were collected using a validated cultural-specific food frequency questionnaire that contained all local Tibetan foods and analyzed with three fixed factors: gender, age, and region. Nutrient intakes were calculated using Chinese food composition tables. Nutritional gaps and the percentages of participants who had inadequate and excessive nutrient intakes were calculated by estimated average requirement (EAR) cut-point methods.ResultsCompared with the dietary reference intakes, 68.4% of nutrient intakes were inadequate. Fiber, Ca, I, Zn, Se, and vitamin (Va, Vc, and folic acid) intakes appeared to be particularly deficient. The dietary energy intake was 7838.8 ± 537.1 KJ/d, with 78 and 84% of EAR values for men and women, respectively. The dietary intakes of most nutrients were below the estimated energy requirement/EAR or adequate intake values, while more than 70% of the participants had excessive intake of carbohydrate, especially the elderly (aged ≥ 51 years). The nutritional gap of Cu was more than 300%. Almost 100% of the participants was vulnerable to fiber, Se, and Va shortfalls due to the deficiency in sole food sources. The top five food sources of Se intake were highland barley (34.2%), meat (13%), rice (12.4%), eggs (12.2%), and cultural-specific beverages (7.8%). Eggs (42.1%), tubers (62.2%), vegetables (66.4%), and highland barley (49.7%) were the first contributors of Va, Ve, Vc, and folic acid, respectively.ConclusionThe dietary intake of a large sample of Tibetan adult population living in agricultural counties of Tibetan Autonomous Region is alarmingly insufficient. Gender inequality is common, and regional difference is widespread due to rapid urbanization. Young Tibetan adults aged 18–30 years are particularly vulnerable to micronutrient shortfalls and currently facing the risk of nutrition-insecurity-related dietary inadequacy. The respondents who belong to the elderly category (≥51 years of age) are facing the risk of “double burden of malnutrition” characterized by the coexistence of undernutrition, including micronutrient deficiencies and overweight or obesity.

District-Level Analysis of Inequality in Malnutrition Among Children: Evidence from Maharashtra, India

Background and Objective: India currently faces the triple burden of malnutrition characterized by the coexistence of undernutrition and overnutrition along with micronutrient deficiencies. The unequal distribution of child health outcomes in the population may affect the goal of a ‘malnutrition free world’. The nutritional status and its inequalities among post under-five age have rarely been assessed in the country. This study examines the degree and extent of asset-based household wealth inequalities in malnutrition among preschool and school children in the Maharashtra state of India. Methods: The study utilizes the fourth round of the District Level Health Survey 2012-2013 to provide district-level estimates of the inequalities in five malnutrition indicators-stunting, wasting, underweight, overweight, and anemia among children. Concentration curves, normalized concentration index, geographical maps and correlation matrix are used to analyze the data by districts, rural-urban residence and gender. Results: Considerable proportion of children are malnourished in Maharashtra, even with its advanced economic status. Malnutrition levels among school going children are as high as those of children under six years of age. The findings indicate that malnutrition inequalities manifest primarily among the weaker sections of society. However, children from affluent households are more likely to suffer from overweight and obesity issues. The prevalence of malnutrition is higher in rural areas, but inequality is significantly higher in urban regions. The nutritionally backward areas are concentrated in the tribal districts of the Marathwada division and a few others from Vidarbha and Amravati. Many districts of Maharashtra have multiple burdens of malnutrition and have high inequalities on more than one indicator. A negative correlation is observed between the prevalence of malnutrition and human development indicators. Conclusion: There is a need to capture broader age groups in the nutrition monitoring frameworks. Recognizing the regional heterogeneity in the malnutrition prevalence and distribution calls for unique health intervention strategies to specific district targets.

Anemia and undernutrition in intestinally parasitized schoolchildren from Gakenke district, Northern Province of Rwanda.

BackgroundRwanda is a sub-Saharan country, where intestinal parasite infections, anemia and undernutrition coexist. The purpose of this research is to study the relationship between intestinal parasite infections and undernutrition/anemia to clarify the priorities of intervention in the rural area of Gakenke district in the Northern Province of Rwanda.Materials and methodsA total of 674 students from Nemba I School, participated in a cross-sectional study, in which their parasitological and nutritional status were analysed. Statistical analysis was performed by χ2 test, univariate analysis and Odds ratios (OR).ResultsA total of 95.3% of children presented intestinal parasitism, most of whom (94.5%) infected by protozoa and 36.1% infected by soil-transmitted helminths (STH), with Trichuris trichiura (27.3%) being the most prevalent. Multiple infections were found to be high (83.8%), with protozoa and STH co-infections in 30.6%. STH infections were mainly of low/moderate intensity. Neither infection nor STH infection of any intensity profile, was significantly related to anemia. In addition, STH infection, regardless of the intensity profile, was not associated with stunting, underweight or thinness. There was no difference between genders nor among ages in odds of anemia and nutritional status in STH-infected schoolchildren.ConclusionMultiparasitism remains high among Rwandan schoolchildren and is likely to cause nutritional problems. This work emphasizes the importance of keeping up health programs to reduce the prevalence of infection.
