Nutrition disparities and the global burden of malnutrition

Which messages about healthy and sustainable eating resonate best with consumers with low socio-economic status?

Consumers with low socioeconomic status (SES) eat less healthy and sustainable diets than consumers with higher status. This is attributed, at least in part, to inequalities in health communication. An online survey with 134 socioeconomically disadvantaged consumers in Italy was conducted to test the effectiveness of tailor-made communication material (infographics) about healthy and sustainable eating (HSE). Participants were recruited at two social supermarkets by a social service organisation as well as via a crowdsourcing platform. Participants found information about HSE delivered through infographics moderately effective in increasing motivation, capability, and opportunity for HSE, and moderately useful and likely to impact their behaviour. Certain messages were more effective than others for native consumers, while migrants showed more indifferent responses to the various messages and manifested lower motivation to shift towards HSE, limited access to and seeking of nutrition-related information, and lower trust in information sources. Selecting which messages to deliver strategically, while also considering differences between segments of the target audience and their preferred sources and channels for communication, is promising; yet, structural changes related to food's affordability and availability are also needed to facilitate an effective communication.

Critical research gaps in treating growth faltering in infants under 6 months: A systematic review and meta-analysis

In 2020, 149.2 million children worldwide under 5 years suffered from stunting, and 45.4 million experienced wasting. Many infants are born already stunted, while others are at high risk for growth faltering early after birth. Growth faltering is linked to transgenerational impacts of poverty and marginalization. Few interventions address growth faltering in infants under 6 months, despite a likely increasing prevalence due to the negative global economic impacts of the COVID-19 pandemic. Breastfeeding is a critical intervention to alleviate malnutrition and improve child health outcomes, but rarely receives adequate attention in growth faltering interventions. A systematic review and meta-analysis were undertaken to identify and evaluate interventions addressing growth faltering among infants under 6 months that employed supplemental milks. The review was carried out following guidelines from the USA National Academy of Medicine. A total of 10,405 references were identified, and after deduplication 7390 studies were screened for eligibility. Of these, 227 were assessed for full text eligibility and relevance. Two randomized controlled trials were ultimately included, which differed in inclusion criteria and methodology and had few shared outcomes. Both studies had small sample sizes, high attrition and high risk of bias. A Bangladeshi study (n = 153) found significantly higher rates of weight gain for F-100 and diluted F-100 (DF-100) compared with infant formula (IF), while a DRC trial (n = 146) did not find statistically significant differences in rate of weight gain for DF-100 compared with IF offered in the context of broader lactation and relactation support. The meta-analysis of rate of weight gain showed no statistical difference and some evidence of moderate heterogeneity. Few interventions address growth faltering among infants under 6 months. These studies have limited generalizability and have not comprehensively supported lactation. Greater investment is necessary to accelerate research that addresses growth faltering following a new research framework that calls for comprehensive lactation support.

Designing and Evaluating a Nutrition Recommender System for Improving Food Security in a Developing Country

BACKGROUND

Due to the increased price of foods in recent years and the diminished food security in Iran, nutrition recommender systems can suggest the most suitable and affordable foods and diets to users based on their health status and food preferences. Objective: The present study aimed to design and evaluate a recommender system to suggest healthy and affordable meals and provide a tele-nutrition consulting service.

METHODS

This applied three-phase study was conducted in 2020. In the first stage, the food items' daily prices were extracted from credible sources, and accordingly, meals were placed in three price categories. After conducting a systematic review of similar systems, the requirements and data elements were specified and confirmed by 10 nutritionists and 10 health information management and medical informatics experts. In the second phase, the software was designed and developed based on the findings. In the third phase, system usability was evaluated by four experts based on Nielsen's heuristic evaluation.

RESULTS

Initially, 72 meals complying with nutritional principles were placed in three price categories. Following a literature review and expert survey, 31 data elements were specified for the system, and the experts confirmed system requirements. Based on the information collected in the previous stage, the Web-based software TanSa in the Persian language was designed, developed, and presented on a unique domain. During the evaluation, the mean severity of the problems associated with Nielsen's 10 principles was 1.2, which is regarded as minor.

CONCLUSION

To promote food security, the designed system recommends healthy, nutritional, and affordable meals to individuals and households based on user characteristics.

Implementation of strategies and programs for breastfeeding, complementary feeding, and malnutrition of young children in Brazil: advances and challenges

Malnutrition in all its forms has risen on global agendas due to the recognition of its magnitude and consequences for a wide range of human, social, and economic outcomes. Implementing strategies and programs with the needed scale and quality is a major challenge. The Brazilian National Survey on Child Nutrition (ENANI-2019) pointed out several advances but numerous challenges. In this paper, we reflect on the implementation progress of breastfeeding, complementary feeding and young children malnutrition strategies and programs in Brazil and how existing challenges can be overcome through the lens of implementation science. First, we present a brief history of such programs. Second, we selected two breastfeeding initiatives to illustrate and reflect on common implementation challenges. In these case studies, we used the RE-AIM (Reach, Effectiveness, Adoption, Implementation, Maintenance) framework to analyze the implementation and scaling up barriers and facilitators. We found common barriers related to unclear goals about the reach of programs, challenges in assessing effectiveness and fidelity/quality during the real-world implementation, discontinuation or lack of funding, and lack of monitoring and evaluation impacting the sustainability of programs. We also discuss the use of implementation science to achieve adequate nutrition by 2030 and present critical elements for successful scale implementation of nutrition programs based on global evidence. Despite the investment to implement different actions aimed at facing infant feeding and malnutrition, high-quality implementation research must become a priority to catalyze progress in Brazil.

Concurrent Undernutrition and Overnutrition within Indian Families between 2006 and 2021

Background

The double burden of malnutrition (DBM), characterized by concurrent undernutrition and overnutrition, is a growing global concern. Families share resources and eating behaviors and programs often target households, yet evidence of the DBM at the family level is scarce.

Objectives

This study examined trends and inequality in the intrahousehold DBM in India between 2006 and 2021.

Methods

Data were from 3 waves of India's National Family Health Survey (NFHS 2006, 2016, and 2021). We examined 3 types of household member (with children aged <5 y) combinations: mother-child (N = 328,039 across 3 waves), father-child, and parent (mother and father)-child (N = 47,139 for each pair). The DBM was defined as one or more individuals with undernutrition (either wasting or stunting in children or underweight in adults) and one or more overweight individuals within the same household. DBM was examined over time, at national and subnational levels, and by residence and wealth.

Results

Nearly all DBM was in the form of an overweight parent and an undernourished weight or stunted child. The prevalence of parent-child DBM increased from 15% in 2006 to 26% in 2021. Father-child pairs experienced the most rapid DBM increase, from 12% in 2006 to 22% in 2021, an 83% increase, driven by increasing overweight among men. In 2021, the DBM was highest in North-Eastern and Southern states, and among relatively rich households from urban areas. The increase in the DBM was faster in rural areas and among poor households compared with that in urban areas and rich households. Urban-rural and rich-poor inequalities in the DBM have decreased over time.

Conclusions

The intrahousehold DBM has increased over time, affecting 1 in 4 households in India in 2021. Family-based interventions that can simultaneously address child underweight and parent overweight are required to address India's increasing intrahousehold DBM.

Determinants of coexisting forms of undernutrition among under-five children: Evidence from the Bangladesh demographic and health surveys

In many underdeveloped and developing countries, epidemiological and nutritional transitions are leading to an increase in malnutrition, resulting in pediatric diseases and eventually deaths. Therefore, this study intents to determine the important factors of the presence of coexisting forms of malnutrition (CFM), i.e., pediatric undernutrition. This study used the latest Bangladesh Demographic and Health Survey (BDHS)-2017/18 dataset consisting of 7127 under-five children. The logistic regression model has been utilized to gain explicit and in-depth knowledge of the relationship between the presence of pediatric undernutrition with socioeconomic and demographic factors. Findings revealed that about 31%, 22%, and 8% suffered from stunted, underweight, and wasted, respectively. The prevalence of stunted, underweighted, wasted, and CFM among children in the Sylhet division is higher than in any other region. A child of a secondary-level completed mother is 27.6% (OR: 0.724, 95% CI: 0.58-0.90) less likely to suffer from undernutrition than a child of an uneducated mother. The rate of undernutrition of children was less among children of highly educated parents. Age, birth order of the child, twin status, mother's age, body mass index (BMI), working status, parental educational qualification, cooking fuel, toilet facility, region, residence, and wealth index are important for determining the nutritional status of a child. The authors believe that the study findings will be helpful to the policymakers to take proper actions for achieving the sustainable development goal (SDGs) by reducing pediatric undernutrition in Bangladesh by 2030.

Global lessons for strengthening breastfeeding as a key pillar of food security

Breastfeeding is identified as a central pillar of food security by the World Health Organization, however globally significant challenges remain in achieving breastfeeding targets for early initiation, exclusive breastfeeding for 6 months, and continued breastfeeding for 2 years and beyond. Inadequate support in health systems, poor maternity protections and workplace policies, and insufficient regulation of commercial milk formulas, among other barriers, continue to undermine this key pillar across nations. This paper highlights the central importance of breastfeeding for food security across diverse global settings by examining three case studies: Honduras, Pakistan and the USA. The cases highlight the complex layering and intersections of key challenges that threaten breastfeeding in the era of pandemics, the climate crisis, conflict and global inequality. Lessons drawn from these case studies, combined with additional insights, reinforce the importance of multisectorial collaboration to scale up investment in creating equitable, enabling environments for breastfeeding. These structural and systems approaches can successfully strengthen the breastfeeding ecosystem to ensure greater first food system resilience in the face of global crises, which compound maternal and infant vulnerabilities. Additionally, the cases add urgency for greater attention to prioritizing breastfeeding and incorporating IYCF-E protocols into disaster preparedness and management into the policy agenda, as well as ensuring that first food security is considered in energy policy. An integrated approach to policy change is necessary to recognize and strengthen breastfeeding as a pivotal part of ensuring food security across the globe.

Attitudes toward COVID-19 Vaccination: Staff and Patient Perspectives at Six Health Facilities in Sierra Leone

Sierra Leone is a West African country with a population of over 8 million. With more than half of Sierra Leone's population living in rural areas, it is important to understand rural populations' access to and attitudes toward the COVID-19 vaccine. In November 2021, the rate of vaccination coverage in Sierra Leone was only 7% for one dose and 4% for two doses. Understanding perspectives of health facility staff and patients can help strengthen future vaccine campaigns. We conducted a cross-sectional study, between March 2022 and May 2022, of clinical staff, non-clinical staff, and adult (>18 years) patients/caregivers attending six Ministry of Health and Sanitation (MoHS) facilities supported by Partners In Health, four in the Kono district and two in the Western Urban Area district, the capital of Sierra Leone. We assessed the opportunity to vaccinate, vaccine uptake, and intention to vaccinate. Out of the 2015 participants, 11.4% were clinical staff, 18.8% were non-clinical staff, and 69.8% were patients/caregivers. Less than half of the patients/caregivers had the opportunity to be vaccinated (42%), and 22% of patients/caregivers were fully vaccinated. Among the unvaccinated population, 44% would refuse a vaccine if offered to them at no cost. Lack of access to COVID-19 vaccines and to official education messaging, especially for patients and caregivers, is still an underlying problem in Sierra Leone for vaccine uptake, rather than a lack of willingness to be vaccinated.

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

Background

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.

Methods

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.

Results

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.

Conclusions

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.

The double burden of malnutrition and gross motor development in infants: A cross-sectional study

OBJECTIVE

The objective of the present work was to study the relationship between the double burden of malnutrition and gross motor development in infants.

METHOD

ology: Sample included 5900 infants under 24 months of age, participants of the ENSANUT-ECU study. To evaluate nutritional status, we calculated z-scores for body mass index/age (BAZ) and height/age (HAZ). Six gross motor milestones were considered: sitting without-support, crawling, standing and walking with-support, standing and walking without-support. Data was analysed using logistic regression models in R.

RESULTS

Independently form age, sex and other socio-economic factors, the probability of achieving three gross motor milestones was significantly lower among chronically undernourished infants compared to their peers: sitting without-support, crawling, and walking without-support. Compared to no malnourished infants the probability of sitting without-support at six months was 10% lower for chronically undernourished infants (0.70, 95%CI [0.64-0.75]; 0.60, 95%CI [0.52-0.67]; respectively). The probability of crawling at eight months and walking without-support at 12 months were also significantly lower among chronically undernourished infants (0.62, 95%CI [0.58-0.67]); 0.25, 95%CI [0.20-0.30]; respectively) in comparison to no malnourished infants (0.67, 95%CI [0.63-0.72]); 0.29, 95%CI [0.25-0.34]; respectively). Obesity/overweight was not associated with the achievement of gross motor milestones, except for sitting without-support. Chronically undernourished infants with low or high BMI/age were generally delayed in the achievement of gross motor milestones than their peers.

CONCLUSIONS

Chronic undernutrition is related to delayed gross motor development. Public health measures are needed to be implemented to prevent the double burden of malnutrition and its detrimental effects on infant development.

A Mixed Methods Exploration of the Role of Participation in a Nutrition-Sensitive Agroecology Intervention in Rural Tanzania

Background

Participation is key to the successful implementation of nutrition-related interventions, but it has been relatively overlooked.

Objective

We sought to describe participation intensity among smallholder farmers in a randomized nutrition-sensitive agroecology study in rural Tanzania. We explored the association between baseline characteristics and overall participation intensity (quantitatively at the individual level and qualitatively at the group level), the association of participation intensity with 2 process indicators, and the association between participation intensity and key study outcomes.

Methods

Data came from 7 rounds of surveys with 295 women and 267 men across 29 months and 2 rounds of semi-structured interviews with the 20 "mentor farmers" who delivered the intervention. Participation intensity was based on the number of months of attendance at village-level project meetings or household visits (range: 0-29). Multivariable models of participation were built.

Results

Women and men participated for 17.5 ± 7.2 and 13.6 ± 8.3 months, respectively. Participation intensity followed 1 latent trajectory: initially low, with a sharp increase after month 7, and plateaued after the first year. At baseline, higher participation intensity was associated with older age, higher education, level of women's empowerment, being in the middle quintile of wealth, and qualitatively, village residence. Higher participation intensity was associated with 2 process indicators - better recall of topics discussed during meetings and greater knowledge about key agroecological methods. High participation intensity was positively associated with increased use of sustainable agricultural practices among all participants, and among women, with husband's involvement in household tasks and child's dietary diversity score.

Conclusions

Participation intensity covaried with key study outcomes, suggesting the value of increased attention to implementation in nutrition-related programs for providing insights into drivers of impact. We hope that investigations of participation, including participation intensity, will become more widespread so that intervention impacts, or lack thereof, can be better understood.

What values drive communities' nutrition priorities in a resource constrained urban area in South Africa?

BACKGROUND

Voices of under-resourced communities are recognised as important yet are often unheard in decisions about healthcare resource allocation. Deliberative public engagement can serve as an effective mechanism for involving communities in establishing nutrition priorities. This study sought to identify the priorities of community members of a South African township, Soweto, and describe the underlying values driving their prioritisation process, to improve nutrition in the first 1000 days of life.

METHODS

We engaged 54 community members (28 men and 26 women aged > 18 years) from Soweto. We conducted seven group discussions to determine how to allocate limited resources for prioritising nutrition interventions. We used a modified public engagement tool: CHAT (Choosing All Together) which presented 14 nutrition intervention options and their respective costs. Participants deliberated and collectively determined their nutritional priorities. Choices were captured quantitatively, while group discussions were audio-recorded. A thematic analysis was undertaken to identify the reasons and values associated with the selected priorities.

RESULTS

All groups demonstrated a preference to allocate scarce resources towards three priority interventions-school breakfast provisioning, six-months paid maternity leave, and improved food safety. All but one group selected community gardens and clubs, and five groups prioritised decreasing the price of healthy food and receiving job search assistance. Participants' allocative decisions were guided by several values implicit in their choices, such as fairness and equity, efficiency, social justice, financial resilience, relational solidarity, and human development, with a strong focus on children. Priority interventions were deemed critical to supporting children's optimal development and well-being, interrupting the intergenerational cycle of poverty and poor human development in the community.

CONCLUSION

Our study demonstrates how public engagement can facilitate the incorporation of community values and programmatic preferences into nutrition priority setting, enabling a responsive approach to local community needs, especially in resource constrained contexts. Findings could guide policy makers to facilitate more appropriate decisions and to improve nutrition in the first 1000 days of life.

Socioeconomic and urban-rural inequalities in the population-level double burden of child malnutrition in the East and Southern African Region

Socioeconomic and urban-rural inequalities in the population-level double burden of child malnutrition threatens global nutrition targets 2025, especially in East and Southern Africa. We aimed to quantify these inequalities from nationally representative household surveys in the East and Southern African region. 13 Demographic and Health Surveys between 2006 and 2018 including 72,231 children under five years old were studied. Prevalence of stunting, wasting and overweight (including obesity) were disaggregated by wealth quintiles, maternal education categories and urban-rural residence for visual inspection of inequalities. The slope index of inequality (SII) and the relative index of inequality (RII) were estimated for each country. Regional estimates of child malnutrition prevalence and socioeconomic and urban-rural inequalities were generated from pooling country-specific estimates using random-effects meta-analyses. Regional stunting and wasting prevalence were higher among children living in the poorest households, with mothers with the lowest educational level and in rural areas. In contrast, regional overweight (including obesity) prevalence was higher among children living in the richest households, with mothers with the highest educational level and urban areas. This study indicates pro-poor inequalities are present in child undernutrition and pro-rich inequalities are present in child overweight including obesity. These findings re-emphasise the need for an integrated approach to tackling the population-level double burden of child malnutrition in the region. Policy makers must target specific populations that are vulnerable to child malnutrition, to avoid further widening of socioeconomic and urban-rural inequalities.

A systematic review and meta-analysis of the prevalence of childhood undernutrition in North Africa

Undernutrition (stunting, wasting and underweight) among children remains a public health concern in North Africa, especially following recent conflicts in the region. Therefore, this paper systematically reviews and meta-analyses the prevalence of undernutrition among children under five in North Africa to determine whether efforts to reduce undernutrition are on track to achieving the Sustainable Development Goals (SDGs) by 2030. Eligible studies published between 1st January 2006 and 10th April 2022 were searched for, using five electronic bibliographic databases (Ovid MEDLINE, Web of Science, Embase (Ovid), ProQuest and CINAHL). The JBI critical appraisal tool was used, and a meta-analysis was conducted using the 'metaprop' command in STATA, to estimate the prevalence of each undernutrition indicator in the seven North African countries (Egypt, Sudan, Libya, Algeria, Tunisia, Morocco, and Western Sahara). Due to the significant heterogeneity among studies (I2 >50%), a random effect model and sensitivity analysis were conducted to examine the effect of outliers. Out of 1592 initially identified, 27 met the selection criteria. The prevalence of stunting, wasting and being underweight were 23.5%, 7.9% and 12.9%, respectively. Significant variations between the countries with the highest rates of stunting and wasting were reported in Sudan (36%, 14.1%), Egypt (23.7%, 7.5%), Libya (23.1%, 5.9%), and Morocco (19.9%, 5.1%). Sudan also had the highest prevalence of underweight (24.6%), followed by Egypt (7%), Morocco (6.1%), and Libya (4.3%) with more than one in ten children in Algeria and Tunisia having stunted growth. In conclusion, undernutrition is widespread in the North African region, particularly in Sudan, Egypt, Libya, and Morocco, making it challenging to meet the SDGs by 2030. Nutrition monitoring and evaluation in these countries is highly recommended.

The effect of short-term preoperative nutritional intervention for cleft surgery eligibility

BACKGROUND

Children with orofacial clefts are highly susceptible to malnutrition, with severe malnutrition restricting their eligibility to receive safe surgery. Ready-to-use therapeutic foods (RUTF) are an effective treatment for malnutrition; however, the effectiveness has not been demonstrated in this patient population prior to surgery. We studied the effectiveness of short-term RUTF use in transitioning children with malnutrition, who were initially ineligible for surgery, into surgical candidates.

METHODS

A cohort of patients from Ghana, Honduras, Malawi, Madagascar, Nicaragua, and Venezuela enrolled in a nutrition program were followed by Operation Smile from June 2017 to January 2020. Age, weight, and length/height were tracked at each visit. Patients were included until they were sufficiently nourished (Z >  = -1) with a secondary outcome of receiving surgery. The study was part of a collaborative program between Operation Smile (NGO), Birdsong Peanuts (peanut shellers and distributors), and MANA Nutrition (RUTF producer).

RESULTS

A total of 556 patients were recruited between June 2017 and January 2020. At baseline 28.2% (n = 157) of patients were diagnosed with severe, 21.0% (n = 117) moderate, and 50.7% (n = 282) mild malnutrition. 324 (58.3%) presented for at least one return visit. Of those, 207 (63.7%) reached optimal nutrition status. By visit two, the mean z-score increased from -2.5 (moderate) to -1.7 (mild) (p < 0·001). The mean time to attain optimal nutrition was 6 weeks. There was a significant difference in the proportion of patients who improved by country(p < 0.001).

CONCLUSION

Malnutrition prevents many children with orofacial clefts in low- and middle-income countries from receiving surgical care even when provided for free. This creates an even larger disparity in access to surgery. In an average of 6 weeks with an approximate cost of $25 USD per patient, RUTF transitioned over 60% of patients into nutritionally eligible surgical candidates, making it an effective, short-term preoperative nutritional intervention. Through unique partnerships, the expansion of cost-effective, large-scale nutrition programs can play a pivotal role in ensuring those at the highest risk of living with unrepaired orofacial clefts receive timely and safe surgical care.

Growth Anthropometrics as a Metric of Malnutrition Disparities Among Young Children Affected by HIV who are Orphaned Maternally, Paternally, or Totally in Western Kenya: A Retrospective Chart Review

This retrospective study investigated growth outcomes of Kenyan children born to women living with HIV, comparing children who were orphaned maternally, paternally, and totally (both parents deceased) to those who were non-orphaned. We reviewed HIV clinic visits performed in Kenya from January 2011 to August 2016 in children 0 to 4 years of age. Malnutrition was assessed using stunting, underweight status, and wasting (z-scores of ≤-2). Descriptive statistics, Chi-square, t-tests, multivariable logistic regression, and ANCOVA models were performed. Of 15 027 total children in the study population, 3.5% (n = 520) were orphaned maternally, 8.1% (n = 1222) were orphaned paternally, and 2.2% (n = 336) were orphaned totally. Children who were orphans had higher rates of malnutrition compared to non-orphans (P < .001). Children who were orphaned maternally and totally had lower anthropometric mean scores, presented to clinic later, and were more likely to be living with HIV. Children who are orphaned maternally or totally should be targeted in interventional strategies.

Association between food insecurity and perceived stress among older adults (50+) in six low- and middle-income countries

OBJECTIVES

In this study, we assess the relationship between food insecurity andperceived stress among older adults (50+) in six low- and middle-income countries of China, Ghana, India, Mexico, Russia and, South Africa.

METHODS

Cross-sectional comparative analysis was conducted using nationally representative data from the WHO's Study on global AGEing and adult health survey. Bivariate and multivariate regression analyses examine if food insecurity was associated with perceived stress. We also examined the mediating role of health conditions on the association between food insecurity and perceived stress.

RESULTS

Across countries, the mean perceived stress score was higher among the older population with food insecurity. Regression analysis showed significant and positive association between food insecurity and perceived stress. Findings from the pooled data of six countries showed, older adults who experienced severe food insecurity (β = 4.05, p < .001) had higher perceived stress scores. The association was statistically significant in India, Russia, South Africa, and Ghana.

CONCLUSION

Food insecurity showed significant adverse impact on perceived stress among the older population in low- and middle-income countries. Policy measures to reduce household food insecurity are important for improving both mental and physical health conditions of the growing older population in low- and middle-income countries.

Food insecurity, low dietary diversity and poor mental health among Syrian refugee mothers living in vulnerable areas of Greater Beirut, Lebanon

Syrian refugees in Lebanon are facing vulnerabilities that are affecting their food insecurity (FI) levels. The objectives of this study were to measure dietary diversity, FI and mental health status of Syrian refugee mothers in Lebanon and to explore its associations with their anaemia and nutritional status. A cross-sectional study was conducted among mothers with children under 5 years (n 433) in Greater Beirut, Lebanon. Dietary diversity was measured using the Minimum Dietary Diversity for Women (MDD-W) of reproductive age and FI using the global Food Insecurity Experience Scale at the individual level. Depression and post-traumatic stress disorder (PTSD) were measured to assess the maternal mental health status. Data on socio-economic characteristics, anthropometric measurements and Hb concentrations were collected. Overall, 63·3 % of the mothers had a low dietary diversity (LDD) and 34·4 % were moderately to severely food insecure, with 12·5 % being severely food insecure. The prevalence of PTSD, moderate depression and severe depression was 13·2, 11·1 and 9·9 %, respectively. A significant correlation was found between LDD and FI (P < 0·001). Low income was significantly associated with LDD and FI. Poor mental health was significantly associated with FI. LDD and FI were not associated with anaemia and nutritional status of mothers. Low-income households had significantly higher intakes of grains and refined starchy staples, whereas high-income households consumed more nutritious foods and sweets. Evidence of inadequate diet quality, FI and poor mental health among Syrian refugee mothers in Lebanon is presented. Multifaceted actions are needed to reduce FI and improve dietary diversity.

Effects of Nutritional and Social Factors on Favorable Fetal Growth Conditions Using Structural Equation Modeling

Poor birth outcomes such as low birth weight, low birth length and short gestational age, are public health concern issues in South Africa (SA). This study utilized structural equation modeling (SEM) to explore how nutritional and social factors contribute to favorable fetal growth conditions (FFGC) in pregnant women living with and without human immunodeficiency virus (HIV), in the Free State Province of SA. Sociodemographic characteristics, stress, health and nutrition-related information, and birth outcomes data were collected and analyzed from a subsample of 305 women enrolled in a cohort study from 2018−2020. Descriptive statistics were analyzed in R version 4.1.2 and SEM was conducted in Lavaan version 0.6−5. Higher gestational body mass index (GBMI) and income levels were associated with higher FFGC (p < 0.05). Household incomes were positively associated with dietary micronutrient quality (p = 0.002), GBMI (p = 0.012) and food security (p = 0.001). Low incomes (p = 0.004) and food insecurity (p < 0.001) were associated with higher stress, while social support was positively associated with food security status (p = 0.008). These findings highlight the complex interconnections between the social and nutritional factors that are associated with fetal growth conditions. Multisectoral community-based programs may be a useful strategy to address these challenges.

Double burden of malnutrition as a risk factor for overweight and obesity

OBJECTIVE

To assess the longitudinal effect of double burden of malnutrition (DBM) on the risk of developing child and adolescent overweight or obesity.

METHODS

Analysis of the Peruvian Young Lives Study, younger cohort: baseline (2002) and 4 follow-ups (2006-2007, 2009-2010, 2013-2014, and 2016-2017). Outcomes were the incidence of overweight and obesity as defined by the World Health Organization standards. The exposure comprised a variable with 4 categories: non-stunted child with a non-overweight mother (reference group), non-stunted child with an overweight mother, stunted child with a non-overweight mother, and stunted child with an overweight mother (i.e., DBM). Poisson regression models were built to assess the association of interest, and relative risks (RR) and 95%CI were reported.

RESULTS

Data from 2,034 children; 50.0% were girls and the mean age was 12.0 (3.6) months at baseline. Non-stunted children with an overweight mother had greater risk (RR = 1.64; 95%CI: 1.35-1.99) of developing overweight, compared with the risk for stunted children with a non-overweight mother (RR = 1.38; 95%CI: 1.10-1.72), and for those with DBM (RR = 1.28; 95%CI: 1.02-1.61). When compared with the reference group, obesity risk was greater among non-stunted children with an overweight mother (RR = 2.33; 95%CI: 1.68-3.22), greater among stunted children with a non-overweight mother (RR = 2.59; 95%CI: 1.75-3.84), and greater among those with DBM (RR = 2.14; 95%CI: 1.39-3.28).

CONCLUSIONS

DBM is a risk factor for childhood overweight and obesity in Peru. Dual-duty policies tackling both undernutrition in children and overweight in mothers are needed to reduce DBM and its future effects in Peru.

The associations between women's empowerment measures, child growth and dietary diversity: Findings from an analysis of demographic and health surveys of seven countries in Eastern Africa

Evidence on the efficacy of women's empowerment to improve child growth and minimum dietary diversity (MDD) in the Eastern Africa (EA) region is limited. This cross‐sectional study used recent Demographic and Health Survey data of mother–child dyads from seven countries in EA to examine the associations between women's empowerment measures, child growth and MDD. Length‐for‐age z‐scores, weight‐for‐length z‐scores and weight‐for‐age z‐scores were used to categorize growth indicators of 6–23 months old children. Multivariable logistic regression was used to identify significant associations. Among all countries, 32%–59% of children experienced growth failure. Children meeting MDD were 18%–45%. Women having self‐esteem were associated with lower odds of stunting (adjusted odds ratio [AOR] = 0.62 in Rwanda), wasting (AOR = 0.38 in Uganda), underweight (AORs = 0.60 and 0.57 in Tanzania and Uganda, respectively) and growth failure (AOR = 0.64 in Rwanda). Having health decision control in Burundi was associated with lower odds of stunting (AOR = 0.49) and child growth failure (AOR = 0.52) and higher odds of meeting MDD (AOR = 2.50). Having Legal empowerment among women increased the odds of stunting (AOR = 1.79 in Burundi), underweight (AOR = 1.77 in Uganda) and growth failure (AOR = 1.87 in Burundi). Economic empowerment showed mixed associations with child growth and MDD among some countries. Women's self‐esteem and health decision control were associated with better child growth and MDD for some countries in EA. Nutrition‐sensitive interventions aimed at improving child growth and MDD should consider local contexts when addressing women's empowerment.

Understanding the associations between women's empowerment, child growth and child dietary diversity is important for most nutrition‐sensitive interventions seeking to improve child feeding practices and growth by targeting mothers.

In this study, for women to have self‐esteem and health decision control was consistently beneficial for child growth and minimum dietary diversity (MDD). Mixed associations existed among other women's empowerment measures, child growth and MDD across the seven East African countries investigated.

For improved child growth and better child dietary diversity, targeting specific women's empowerment measures based on local context may be beneficial in the East African region.

China is implementing the national nutrition plan of action

With the transformation of Chinese economic and social structure, the social determinants of nutrition have undergone significant changes, which have a great influence on the dietary patterns and nutrition status of its population. The transition in the structure of nutrition intake in China can be characterized by a rapid trend in food accessibility, affordability, and diversity. However, challenges, such as the triple burden of malnutrition (undernourishment, micronutrient deficiencies, and obesity), still seriously threaten the population's health. To approach the targets for the “Healthy China 2030,” the General Office of the State Council of the People's Republic of China issued the National Nutrition Plan of Action (2017–2030), which specifies multi-sectoral transdisciplinary measures to improve population nutrition status. In our study, we recognized the role of the National Nutrition Plan of China in responding to the call for the Sustainable Development Goals (SDGs). Under the global- and country-level targets, this paper presented six primary intervention measures specified in the National Nutrition Plan of Action in China, highlighting the importance of collaborative actions for participants in all sectors.

Association between mother’s work status and child stunting in urban slums: a cross-sectional assessment of 346 child-mother dyads in Dhaka, Bangladesh (2020)

Background

A growing literature highlights the increased risk of stunting among children growing up in informal or slum settlements. Despite relatively high rates of female labor force participation in slums, there is limited evidence on relationship between mother’s work participation and nutritional outcomes of children in these settings.

Methods

We conducted a cross-sectional study in two large slums (Korail and Tongi) of Dhaka and Gazipur, Bangladesh to assess the association between maternal work and childhood stunting in a low-income urban context. Logistic regression models estimated unconditional and conditional associations between maternal work status and 1) child stunting, 2) child morbidity and dietary intake, and 3) health and hygiene behaviors. Subgroup analyses were done by type of child care support available.

Results

After adjusting for variations in individual and household level characteristics, we found that children of working mothers had nearly twice the odds of being stunted than children of non-working mothers (OR 1.84, 95%CI 1.05-3.23). Large differences in stunting were found by available care support: compared to children of non-working mothers, children of working mothers with nuclear-type family support had 4.5 times increased odds of stunting (OR 4.49, 95%CI 1.81-11.12), while no odds differential was found for children of working mothers with an extended-type family support (OR 0.69, 95%CI 0.30-1.59).

Conclusions

Maternal employment is associated with a substantial increase in the odds of child stunting in the slum areas studied. Given that these effects only appear to arise in the absence of adequate family support, integrating appropriate childcare support measures for low-income urban working mothers might be an effective strategy to help reduce the prevalence of chronic undernutrition among slum children.

Perceived intrinsic, social, and environmental barriers for weight management in older Hispanic/Latino adults with obesity

Background

The burden of obesity and chronic disease is increasing in the older US Hispanic/Latino adult population. There is limited evidence on successful weight management strategies as perceived by this population. Assessing barriers and opportunities for weight management using mixed methods is a robust approach to collect in-depth information that can be applied to the development of well-tailored weight management interventions for this population.

Objective

The objective of this study was to assess perceived individual, interpersonal, and environmental factors that influence weight management in older Hispanic/Latino adults.

Methods

This community-based cross-sectional study included 23 Hispanic/Latino older (>50y) adults with obesity (BMI >30 kg/m²). Perceived barriers and opportunities for weight management were assessed through validated questionnaires and focus groups. Prospectively registered on ClinicalTrials.gov (NCT03978416) on 7 June 2019.

Results

In this demographically heterogeneous population, language acculturation was generally low, and the frequency of poor dietary behaviors was high. Participants linked financial strain to lower diet quality, as well as anxiety to uncontrolled eating and food cravings. Social support and trust in healthcare professionals were perceived as priorities for healthy eating. Structural and environmental barriers such as affordability and availability of culturally preferred foods were also identified as influences on food choices and eating behavior.

Conclusions

This study revealed opportunities for culturally tailored weight management interventions in older Hispanic/Latino adults with obesity.

Biological Role of Nutrients, Food and Dietary Patterns in the Prevention and Clinical Management of Major Depressive Disorder

Major Depressive Disorder (MDD) is a growing disabling condition affecting around 280 million people worldwide. This complex entity is the result of the interplay between biological, psychological, and sociocultural factors, and compelling evidence suggests that MDD can be considered a disease that occurs as a consequence of an evolutionary mismatch and unhealthy lifestyle habits. In this context, diet is one of the core pillars of health, influencing multiple biological processes in the brain and the entire body. It seems that there is a bidirectional relationship between MDD and malnutrition, and depressed individuals often lack certain critical nutrients along with an aberrant dietary pattern. Thus, dietary interventions are one of the most promising tools to explore in the field of MDD, as there are a specific group of nutrients (i.e., omega 3, vitamins, polyphenols, and caffeine), foods (fish, nuts, seeds fruits, vegetables, coffee/tea, and fermented products) or dietary supplements (such as S-adenosylmethionine, acetyl carnitine, creatine, amino acids, etc.), which are being currently studied. Likewise, the entire nutritional context and the dietary pattern seem to be another potential area of study, and some strategies such as the Mediterranean diet have demonstrated some relevant benefits in patients with MDD; although, further efforts are still needed. In the present work, we will explore the state-of-the-art diet in the prevention and clinical support of MDD, focusing on the biological properties of its main nutrients, foods, and dietary patterns and their possible implications for these patients.

A Pilot Pre and Post 4 Week Intervention Evaluating the Effect of a Proprietary, Powdered, Plant Based Food on Micronutrient Status, Dietary Intake, and Markers of Health in a Healthy Adult Population

Background

A "balanced, adequate, and varied diet" is recommended as the basis of nutritionally sound diet by the World Health Organisation and national public health agencies. Huel is a proprietary, on-the-go, powdered, plant based food, providing all 26 essential vitamins and minerals, protein, essential fats, carbohydrate, fibre, and phytonutrients.

Objectives

Assessing the effect of solely consuming Huel on micronutrient status, dietary intake and markers of health was achieved through a 4-week intervention of solely Huel powder.

Methods

Habitual energy intake was assessed through a one-week lead in period with healthy adult participants (aged 18 or over) logging their food intake, after which only Huel was consumed for 4 weeks. Blood samples and body composition was assessed before and after the lead in week as well the end of the intervention. Thirty participants were recruited with 20 (11 females, median age 31, range 22-44) completing the study, 19 sets of blood samples were collected. 22 blood markers were analysed along with weight, BMI, waist circumference, visceral adipose tissue (VAT), and body composition. All blood micronutrients, except for Thyroid Stimulating Hormone and choline were sent to Royal Victoria Infirmary NHS, Newcastle Laboratory (Newcastle upon Tyne, United Kingdom) for analysis.

Results

Fourteen of the parameters significantly changed over the course of the study with circulating haemoglobin, iron, vitamins B12 and D as well as selenium significantly increasing (p < 0.05). HbA1c, total and non-HDL cholesterol, vitamins A and E, potassium, BMI, VAT, and waist circumference all significantly decreased (p < 0.05) post intervention.

Conclusion

Although energy intake decreased during the intervention period, the adherence to recommended micronutrient intake, as quantified by the dietary Total Adherence Score, significantly increased which tallies with the preservation or improvement of micronutrient status. This study potentially demonstrates that consuming only Huel for 4 weeks does not negatively affect micronutrient status.

Food Environments and Their Influence on Food Choices: A Case Study in Informal Settlements in Nairobi, Kenya

The food environments that people have access to shape their food choices. The purpose of this study was to use mixed methods to characterize the external food environment in informal settlements in Nairobi, Kenya and to examine the individual factors that influence the way in which women interact with those environments to make food choices. We used a combination of food environment assessments (vendor mapping, collection of food prices, food quality assessments) and five focus group discussions with women (n = 26) in four villages within two informal settlements in Nairobi (Mukuru and Kibera) to better understand the drivers of food choice. We found a large number (n = 1163) of vendors selling a variety of food within the settlements. The highest number of vendors were selling fruits and/or vegetables; however, there was limited diversity of fruits available. Animal-source foods were considered relatively expensive as compared to plant-based foods, including prepared fried snacks. We found that the way women interacted with their food environments was influenced by individual factors such as income, time, convenience, and preferences. Our findings suggest that interventions targeting both the external food environment as well as individual factors such as income will be necessary to support healthy diets among low-income populations living in informal settlements in Kenya.

Does maternal overnutrition carry child undernutrition in India?

Background and objectives

Studies in low-and middle-income countries where nutrition transition is underway provides mixed evidence of double burden of maternal overnutrition and child undernutrition among mother-child pairs. Shifting dietary pattern and rapid increase in overweight/obesity among adults with persistent child undernutrition indicate that India is experiencing nutrition transition and double burden of malnutrition. Hence, the study explores the presence of and the factors associated with mother-child dyads of over- and undernutrition in India.

Methods and materials

The study uses National Family Health Survey 2015–16 data. The analytic sample consists of 28,817 weighted mother-child pairs where an overweight/obese mother is paired with an undernourished child. The nutritional status of children is defined according to WHO 2006 child growth standards as underweight (i.e., low weight-for-age), stunting (i.e., low height-for-age) and wasting (i.e., low weight-for-height). Maternal overweight/obesity (i.e., BMI ≥ 25 kg/m²) is defined using adult BMI criterion. Descriptive, bivariate, and adjusted multivariable logistic regression analysis are conducted.

Results

Of the overweight/obese mothers, 21.3%, 26.5%, and 14% have underweight, stunted, and wasted children respectively. In adjusted models, maternal short stature (aOR: 2.94, 95% CI: 2.30–3.75), age of child (aOR: 3.29, 95% CI: 2.76–3.92), and poorest wealth status (aOR: 2.01, 95% CI: 1.59–2.54) are significant predictors of overweight/obese mothers and stunted child pairs. Similarly, poor wealth status (aOR: 1.68, 95% CI:1.32–2.14), maternal stature (aOR: 2.70, 95% CI: 2.08–3.52), and child aged 2–5 years (aOR: 1.77, 95% CI:1.51–2.08) are also significantly associated with higher occurrence of overweight/obese mother and-underweight child pairs.

Conclusion

Findings of the study are consistent with the phase of nutrition transition and double burden of malnutrition. The paper concludes with suggestions to improve the socioeconomic condition, more strategic nutrition specific investments and policy interventions to eliminate all forms of malnutrition for achieving SDGs.

Genotypic variations for tuber nutrient content, dry matter and agronomic traits in tetraploid potato germplasm

Nutrient deficiencies lead to various health issues and are common worldwide. Potato germplasm is a rich source of natural variations and genetic variability present in it can be exploited for developing nutrient-rich high-yielding potato varieties. In this study, variations in the yield, dry matter (DM) and mineral nutrients concentrations were evaluated in both peeled and unpeeled tubers of 243 highly diverse tetraploid potato accessions. These were raised under field conditions for two consecutive years. The germplasm studied has a wider range of variations in peeled tubers DM (13.71-27.80%), Fe (17.08-71.03 mg/kg), Zn (9.55-34.78 mg/kg), Cu (2.13-13.25 mg/kg), Mn (7.04-25.15), Ca (117.4-922.5 mg/kg), Mg (656.6-1510.6 mg/kg), S (1121.3-3765.8 mg/kg), K (1.20-3.09%), P (0.21-0.50%) and Mo (53.6-1164.0 ppb) concentrations compared to popular Indian potato varieties. Higher nutrient concentrations in whole tubers compared to tuber flesh suggest that these are present in high concentration in the tuber peripheral layers and peeling off the tubers results in the loss of nutrients. Highest loss due to peeling off the tubers was observed in Fe (35.63%) followed by Cu (22.80%), Mn (21.69%), Ca (21.27%), Mg (12.89%), K (12.75%), Zn (10.13%), and Mo (9.87%). The GCV and PCV for all the traits in peeled tubers ranged from 9.67 to 29.91%, and 13.84 to 43.32%, respectively. Several significant positive correlations were observed among the parameters and the first two principal components accounted for 39.37% of total variations. The results of this study will pave a way for the development of nutrient-rich high-yielding potato varieties.

Perceptions of the local food environment and fruit and vegetable intake in the Eastern Caribbean Health Outcomes research Network (ECHORN) Cohort study

INTRODUCTION

Studies conducted in the US and other high-income countries show that the local food environment influences dietary intakes that are protective for cardiovascular health.However, few studies have examined this relationship in the Caribbean. This study aimed to determine whether perceptions of the local food environment were associated with fruit and vegetable (FV) intake in the Eastern Caribbean, where daily FV intake remains below recommended levels.

METHODS

Cross-sectional analysis of Eastern Caribbean Health Outcomes Research Network Cohort Study (ECS) baseline data (2013-2016) from Barbados, Puerto Rico, Trinidad and Tobago, and US Virgin Islands was conducted in 2020. The National Cancer Institute Dietary Screener Questionnaire was adapted to measure daily servings of FV. Existing scales were used to assess participant perceptions of the food environment (availability, affordability, and quality). Chi-square tests and Poisson regression were used for analyses.

RESULTS

Participants reported eating one mean daily serving of FV. Mean daily intake was higher among those who perceived FV as usually/always affordable, available, and high quality. Multivariate results showed statistically significant associations between FV and affordability. Persons who perceived FV as affordable had 0.10 more daily servings of FV compared to those who reported FV as not always affordable (p = 0.02). Food insecurity modified the association between affordability and FV intake.

CONCLUSIONS

This study highlights the importance of affordability in consumption of FV in the Eastern Caribbean, and how this relationship may be modified by food insecurity.

Short-term effectiveness of nutrition therapy to treat type 2 diabetes in low-income and middle-income countries: systematic review and meta-analysis of randomised controlled trials

OBJECTIVES

This review examined the evidence arising from randomised controlled trials regarding the impact of nutrition therapy on glycaemic control in people living with type 2 diabetes mellitus (T2DM) in low/middle-income countries (LMICs).

DESIGN

Systematic review and meta-analysis using the Grading of Recommendations, Assessment, Development and Evaluation (GRADE) Approach.

DATA SOURCES

MEDLINE, EMBASE, Web of Science, OpenGrey and the International Clinical Trials Registry were searched (up to July 3 2020).

ELIGIBILITY CRITERIA

Trials were included if they evaluated nutrition therapy in adults diagnosed with T2DM, were conducted in LMICs, measured glycaemic control and the trial included a 3-month post-intervention assessment. Nutrition therapy was defined according to American Diabetes Association recommendations.

DATA EXTRACTION AND SYNTHESIS

Two independent reviewers screened the database. Study characteristics and outcome data were extracted using a data collection form. Meta-analyses were conducted for glycated haemoglobin (HbA1c) and fasting blood glucose. Trials were assessed for risk of bias (Cochrane Risk-of-Bias, Version 2.0) and overall certainty of evidence (GRADE).

RESULTS

Four trials met inclusion criteria (total n=463), conducted in Malaysia, Iran and South Africa. All trials focused on nutrition education with no direct prescription or manipulation of diet. Mean differences between intervention and standard care were -0.63% (95% CI -1.47% to 0.21%) for HbA1c and -13.63 mg/dL (95% CI -37.61 to 10.34) for fasting blood glucose in favour of the intervention. Given the small number of eligible trials, moderate to high risk of publication bias and serious concerns regarding consistency and precision of the evidence, certainty of evidence was deemed to be very low.

CONCLUSIONS

There is a lack of well-conducted randomised controlled trials that examine the long-term impact of nutrition therapy in LMICs, preventing firm conclusions to be made on their effectiveness. Further research is essential to discover realistic, evidence-based solutions.

Metabolic syndrome in childhood cancer survivors: delta BMI a risk factor in lower-middle-income countries

PURPOSE

Metabolic syndrome (MetSyn) is an important late effect of childhood cancer. The combination of rising obesity and high prevalence of under-nutrition at diagnosis makes this a unique population to study in LMIC (lower middle-income countries).

METHODS

Children ≤ 18 years of age at cancer diagnosis, in a single center in a LMIC, who were disease free and had completed treatment at least 2 years prior to study were included. MetSyn was defined using International Federation for Diabetes criteria for Asian Indians. Logistic regression analyses were carried out to evaluate the influence of various risk factors, including delta BMI (increase in body mass index from diagnosis to evaluation), on MetSyn.

RESULTS

A high prevalence of MetSyn (12.2%), central obesity (33%), and dyslipidemia (61.8%) were found in a cohort of 500 Asian Indian childhood cancer survivors (CCS) at a median follow-up age of 17 years. Multivariable analysis revealed older age at diagnosis ≥ 10 years, OR 2.9 (1.6-5); longer survival duration ≥ 10 years, OR 2.2 (1.3-3.8); high BMI at diagnosis, OR 3.2 (1.5-6.9); and large delta BMI ≥ 50, OR 3.15(1.7-5.9) to be independent predictors of MetSyn. Patients who were underweight or normal at diagnosis with large delta BMI ≥ 50 had very high odds (OR, 12.5, 1.7-92) of developing MetSyn compared to those with lower delta BMI.

CONCLUSIONS AND IMPLICATIONS FOR CANCER SURVIVORS

A high prevalence of MetSyn was observed in CCS with early age at onset. Timely screening and early intervention are proven to be beneficial and delta BMI could be a useful screening tool for LMIC.

Multilevel Analysis of the Nutritional and Health Status among Children and Adolescents in Eastern China

We aimed to identify multiple nutritional health problems and the relevant factors among children and adolescents aged 7–17 years. This study was part of the China Nutrition and Health Surveillance of Children and Lactating Mothers in 2016–2017, conducted in Jiangsu Province in eastern China. After sampling, 3025 school-age children and adolescents were enrolled into this study. Demographic information collections and anthropometric measurements were conducted by trained local Center for Disease Control and Prevention (CDC) staff. Venous blood in the amount of 6 mL was drawn from each participant in the morning and used for testing biochemical and nutritional indicators. Multivariate logistic regression analysis and Poisson regression analysis were used for overnutrition- and undernutrition-related disorders to test relevant personal, parental, and household factors. The prevalence of wasting, overweight, and obesity was 5.5%, 14.8%, and 12.7%, respectively. Metabolic syndrome (MetS) was prevalent among 5.1% of participants. Among the study participants, 29.5% had hyperuricemia. The overall prevalence of high low-density lipoprotein (LDL) and high total cholesterol (TC) of all participants was 4.8% and 7.4%, respectively. 0.9% of the participants had vitamin A deficiency (VAD) and 14.6% had marginal vitamin A deficiency; 25.1% had vitamin D deficiency (VDD) and 54.5% had inadequate vitamin D levels. Anemia was present in 4.0% of all participants. The prevalence of zinc deficiency was 4.8%. Demographic characteristics, behavioral characteristics, parents’ characteristics, and family characteristics were associated with these multiple malnutrition disorders. The double burdens of malnutrition, which includes overnutrition- and undernutrition-related diseases, were prevalent among the school-age children and adolescents in Jiangsu Province in eastern China. There were various factors related to different nutritional problems. Thus, health education focusing on behavior intervention and nutrition education are necessary in containing nutritional problems among children.

The Online Ordering Behaviors among Participants in the Oklahoma Women, Infants, and Children Program: A Cross-Sectional Analysis

The Special Supplemental Nutrition Program for Women, Infants, and Children (WIC) is a nutrition assistance program in the United States (U.S.). Participants in the program redeem their prescribed food benefits in WIC-authorized grocery stores. Online ordering is an innovative method being pilot-tested in some stores to facilitate WIC participants’ food benefit redemption, which has become especially important in the COVID-19 pandemic. The present research aimed to examine the online ordering (OO) behaviors among 726 WIC households who adopted WIC OO in a grocery chain, XYZ (anonymous) store, in Oklahoma (OK). These households represented approximately 5% of WIC households who redeemed WIC benefits in XYZ stores during the study period, which was 1 July to 31 December 2020. This period was during the COVID-19 pandemic but after the temporary lockdown in Oklahoma had been lifted. Descriptive statistics were estimated for WIC OO households’ adoption behaviors and their orders. The Cox proportional hazard model and zero-truncated negative binomial regression were applied to examine the relationship between participants’ socio-demographics and the length of time between 1 July 2020, and their first OO, as well as the number of WIC online orders. About 80% of these online orders were picked up without any changes. Minority households had a significantly longer time before adopting their first OO (hazard ratio (HR) < 1, p < 0.001), while households with a child or a woman participant, or more participants, had a shorter time before adopting OO (HR > 1, p < 0.05). Non-Hispanic black households had a fewer number of OOs than non-Hispanic white households (B = −0.374, p = 0.007). OO adoption varied across socio-demographics. More efforts are needed to ensure equal access and adoption of WIC OO.

Clinical and public policy interventions to address food insecurity among children

PURPOSE OF REVIEW

This article describes the impacts of food insecurity (FI) on child health, outlines clinical and public policy interventions to mitigate FI in children, and defines new paradigms in population health to ameliorate the harmful effects of FI in children.

RECENT FINDINGS

Rates of FI among children have dramatically increased with the onset of the COVID-19 pandemic, with particular adverse impact on low-income children. Population health innovations in screening, referral, and social service integration offer new opportunities to address FI.

SUMMARY

Despite advances in clinical practice and public policy, FI remains a persistent issue for many US children. Clinicians and policymakers have opportunities to leverage clinical and community-based integration to improve service delivery opportunities to ameliorate childhood hunger and racial and socioeconomic inequity in the United States.

Grandi Byen-supporting child growth and development through integrated, responsive parenting, nutrition and hygiene: study protocol for a randomized controlled trial

BACKGROUND

Poor child growth and development outcomes stem from complex relationships encompassing biological, behavioral, social, and environmental conditions. However, there is a dearth of research on integrated approaches targeting these interwoven factors. The Grandi Byen study seeks to fill this research gap through a three-arm longitudinal randomized controlled trial which will evaluate the impact of an integrated nutrition, responsive parenting, and WASH (water, sanitation and hygiene) intervention on holistic child growth and development.

METHODS

We will recruit 600 mother-infant dyads living in Cap-Haitien, Haiti and randomize them equally into one of the following groups: 1) standard well-baby care; 2) nutritional intervention (one egg per day for 6 months); and 3) multicomponent Grandi Byen intervention (responsive parenting, nutrition, WASH + one egg per day for 6 months). Primary outcomes include child growth as well as cognitive, language, motor, and social-emotional development. The study also assesses other indicators of child health (bone maturation, brain growth, diarrheal morbidity and allergies, dietary intake, nutrient biomarkers) along with responsive parenting as mediating factors influencing the primary outcomes. An economic evaluation will assess the feasibility of large-scale implementation of the interventions.

DISCUSSION

This study builds on research highlighting the importance of responsive parenting interventions on overall child health, as well as evidence demonstrating that providing an egg daily to infants during the complementary feeding period can prevent stunted growth. The multicomponent Grandi Byen intervention may provide evidence of synergistic or mediating effects of an egg intervention with instruction on psychoeducational parenting and WASH on child growth and development. Grandi Byen presents key innovations with implications for the well-being of children living in poverty globally.

Global variation in the cost of a nutrient-adequate diet by population group: an observational study

BACKGROUND

Nutrient deficiencies limit human development and could be caused by the high cost of locally available foods needed to meet nutrient requirements. We aimed to identify the populations whose nutrient needs are most difficult to meet with existing global food systems.

METHODS

In this observational study, we used the International Comparison Program 2017 collection of global food prices to measure cost per day and cost per calorie of meeting nutrient needs, based on least-cost diets within upper and lower bounds for energy and 20 nutrients for healthy populations across 20 demographic groups in 172 countries. We then analysed the composition of these least-cost diets by food groups to estimate how the affordability of foods for meeting nutrient needs varied by age, sex, and reproductive status.

FINDINGS

In 2017, the global median of diet costs per day was US$2·32 (IQR 1·95-2·76), with cost highest for adolescent boys aged 14-18 years at $2·72 (2·31-3·15). For females, median cost was highest for adolescents aged 14-18 years during pregnancy and lactation at $2·64 (2·29-3·15), exceeding the cost for adult men aged 19-30 years. The global median of diet cost per 1000 kcal was $0·94 (IQR 0·80-1·12), and was higher for females throughout the life course than for males, peaking for adolescent girls aged 9-13 years ($1·17 [95% CI 1·15-1·19]) and women older than 70 years ($1·18 [1·17-1·19]). Diet costs were most sensitive to requirements for calcium, iron, zinc, and vitamins C and E, as well as the upper bounds on carbohydrates and sodium. Total diet costs per day did not vary significantly with national income; however, in high-income countries, the composition of least-cost diets included more animal-source foods, whereas in low-income countries, diets with more pulses, nuts and seeds, and fruits and vegetables provided the most affordable way to meet nutrient requirements.

INTERPRETATION

Diets with adequate nutrients were unaffordable for many demographic groups, especially women and girls. These results could help to guide agriculture and food policy or transfer programmes to support populations at risk of inadequate intake.

Prevalence, Trends, and Socioeconomic Determinants of Coexisting Forms of Malnutrition Amongst Children under Five Years of Age in Pakistan

In Pakistan, malnutrition is a chronic issue. Concerns regarding coexisting forms of malnutrition (CFM) in an individual child are emerging, as children suffering from CFM have a 4 to 12-fold higher risk of death compared with healthy children. This study assessed the prevalence, trends, and socioeconomic determinants of various types of CFM using Pakistan Demographic and Health Survey (PDHS) datasets. Data from children aged 0-5 years old, with complete height and weight information, and valid anthropometry, from all regions of Pakistan (except residents of Azad Jammu Kashmir (AJK) and Federally Administered Tribal Areas (FATA), and non-de jure residents), were included. The prevalence of CFM was 30.6% in 2012-2013 and 21.5% in 2017-2018 PDHS. Both PDHSs reported a significantly higher prevalence of CFM in Sindh and Baluchistan compared with other regions of Pakistan. Improved socioeconomic status significantly reduced the odds of various types of CFM, except the coexistence of underweight with wasting. The high prevalence of CFM in Pakistan can be averted by multisectoral collaboration and by integrating nutrition-sensitive and nutrition-specific interventions.

Time trends and social inequalities in child malnutrition: nationwide estimates from Brazil's food and nutrition surveillance system, 2009-2017

OBJECTIVE

In Brazil, national estimates of childhood malnutrition have not been updated since 2006. The use of health information systems is an important complementary data source for analysing time trends on health and nutrition. This study aimed to examine temporal trends and socio-demographic inequalities in the prevalence of malnutrition in children attending primary health care services between 2009 and 2017.

DESIGN

Time trends study based on data from Brazil's Food and Nutrition Surveillance System. Malnutrition prevalence (stunting, wasting, overweight and double burden) was annually estimated by socio-demographic variables. Prais-Winsten regression models were used to analyse time trends. Annual percent change (APC) and 95 % CI were calculated.

SETTING

Primary health care services, Brazil.

PARTICIPANTS

Children under 5 years old.

RESULTS

In total, 15,239,753 children were included. An increase in the prevalence of overweight (APC = 3·4 %; P = 0·015) and a decline in the prevalence of wasting (-6·2 %; P = 0·002) were observed. The prevalence of stunting (-3·2 %, P = 0·359) and double burden (-1·4 %, P = 0·630) had discrete and non-significant reductions. Despite the significant reduction in the prevalence of undernutrition among children in the most vulnerable subgroups (black, conditional cash transfer's recipients and residents of poorest and less developed areas), high prevalence of stunting and wasting persist alongside a disproportionate increase in the prevalence of overweight in these groups.

CONCLUSIONS

The observed pattern in stunting (high and persistent prevalence) and increase in overweight elucidate setbacks in advances already observed in previous periods and stresses the need for social and political strategies to address multiple forms of malnutrition.

Scoping Review of Intervention Strategies for Improving Coverage and Uptake of Maternal Nutrition Services in Southeast Asia

Maternal undernutrition can lead to protein-energy malnutrition, micronutrient deficiencies, or anemia during pregnancy or after birth. It remains a major problem, despite evidence-based maternal-nutrition interventions happening on ground. We conducted a scoping review to understand different strategies and delivery mechanisms to improve maternal nutrition, as well as how interventions have improved coverage and uptake of services. An electronic search was conducted in PubMed and Google Scholar for published studies reporting on the effectiveness of maternal-nutrition interventions in terms of access or coverage, health outcomes, compliance, and barriers to intervention utilization. The search was limited to studies published within ten years before the initial search date, 8 November 2019; later, it was updated to 17 February 2021. Of 31 studies identified following screening and data extraction, 22 studies were included for narrative synthesis. Twelve studies were reported from India and eleven from Bangladesh, three from Nepal, two from both Pakistan and Thailand (Myanmar), and one from Indonesia. Nutrition education and counselling, home visits, directly observed supplement intake, community mobilization, food, and conditional cash transfer by community health workers were found to be effective. There is a need to incorporate diverse strategies, including various health education approaches, supplementation, as well as strengthening of community participation and the response of the health system in order to achieve impactful maternal nutrition programs.

Socioeconomic inequalities in child growth failure in Ethiopia: findings from the 2000 and 2016 Demographic and Health Surveys

OBJECTIVE

Socioeconomic inequalities in child growth failure (CGF) remain one of the main challenges in Ethiopia. This study examined socioeconomic inequalities in CGF and determinants that contributed to these inequalities in Ethiopia.

METHODS

The Ethiopia Demographic and Health Surveys 2000 and 2016 data were used in this study. A pooled unweighted sample of the two surveys yielded 21514 mother-child pairs (10873 in 2000 and 10641 in 2016). We assessed socioeconomic inequalities in CGF indicators using the concentration curve and concentration index (CI). We then decomposed the CI to identify percentage contribution of each determinant to inequalities.

RESULTS

Socioeconomic inequalities in CGF have increased in Ethiopia between 2000 and 2016. The CI increased from -0.072 and -0.139 for stunting, -0.088 and -0.131 for underweight and -0.015 and -0.050 for wasting between 2000 and 2016, respectively. Factors that mainly contributed to inequalities in stunting included geographical region (49.43%), number of antenatal care visits (31.40%) and child age in months (22.20%) in 2000. While in 2016, inequality in stunting was contributed mainly by wealth quintile (46.16%) and geographical region (-13.70%). The main contributors to inequality in underweight were geographical regions (82.21%) and wealth quintile (27.21%) in 2000, while in 2016, wealth quintile (29.18%), handwashing (18.59%) and access to improved water facilities (-17.55%) were the main contributors. Inequality in wasting was mainly contributed to by maternal body mass index (-66.07%), wealth quintile (-45.68%), geographical region (36.88%) and paternal education (33.55%) in 2000, while in 2016, wealth quintile (52.87%) and urban areas of residence (-17.81%) were the main driving factors.

CONCLUSIONS

This study identified substantial socioeconomic inequalities in CGF, and factors that relatively contributed to the disparities. A plausible approach to tackling rising disparities may involve developing interventions on the identified predictors and prioritising actions for the most socioeconomically disadvantaged groups.

Understanding urban inequalities in children's linear growth outcomes: a trend and decomposition analysis of 39,049 children in Bangladesh (2000-2018)

BACKGROUND

Despite significant progress in reducing child undernutrition, Bangladesh remains among the top six countries globally with the largest burden of child stunting and has disproportionately high stunting prevalence among the urban poor. We use population representative data to identify key predictors of child stunting in Bangladesh and assess their contributions to linear growth differences observed between urban poor and non-poor children.

METHODS

We combined six rounds of Demographic and Health Survey data spanning 2000-2018 and used official poverty rates to classify the urban population into poor and non-poor households. We identified key stunting determinants using stepwise selection method. Regression-decomposition was used to quantify contributions of these key determinants to poverty-based intra-urban differences in child linear growth status.

RESULTS

Key stunting determinants identified in our study predicted 84% of the linear growth difference between urban poor and non-poor children. Child's place of birth (27%), household wealth (22%), maternal education (18%), and maternal body mass index (11%) were the largest contributors to the intra-urban child linear growth gap. Difference in average height-for-age z score between urban poor and non-poor children declined by 0.31 standard deviations between 2000 and 2018. About one quarter of this observed decrease was explained by reduced differentials between urban poor and non-poor in levels of maternal education and maternal underweight status.

CONCLUSIONS

Although the intra-urban disparity in child linear growth status declined over the 2000-2018 period, socioeconomic gaps remain significant. Increased nutrition-sensitive programs and investments targeting the urban poor to improve girls' education, household food security, and maternal and child health services could aid in further narrowing the remaining linear growth gap.

Crème de la Créature: Dietary Influences on Behavior in Animal Models

In humans, alterations in cognitive, motivated, and affective behaviors have been described with consumption of processed diets high in refined sugars and saturated fats and with high body mass index, but the causes, mechanisms, and consequences of these changes remain poorly understood. Animal models have provided an opportunity to answer these questions and illuminate the ways in which diet composition, especially high-levels of added sugar and saturated fats, contribute to brain physiology, plasticity, and behavior. Here we review findings from invertebrate (flies) and vertebrate models (rodents, zebrafish) that implicate these diets with changes in multiple behaviors, including eating, learning and memory, and motivation, and discuss limitations, open questions, and future opportunities.

Potato biofortification: an effective way to fight global hidden hunger

Hidden hunger is leading to extensive health problems in the developing world. Several strategies could be used to reduce the micronutrient deficiencies by increasing the dietary uptake of essential micronutrients. These include diet diversification, pharmaceutical supplementation, food fortification and crop biofortification. Among all, crop biofortification is the most sustainable and acceptable strategy to overcome the global issue of hidden hunger. Since most of the people suffering from micronutrient deficiencies, have monetary issues and are dependent on staple crops to fulfil their recommended daily requirements of various essential micronutrients. Therefore, increasing the micronutrient concentrations in cost effective staple crops seems to be an effective solution. Potato being the world's most consumed non-grain staple crop with enormous industrial demand appears to be an ideal candidate for biofortification. It can be grown in different climatic conditions, provide high yield, nutrition and dry matter in lesser time. In addition, huge potato germplasm have natural variations related to micronutrient concentrations, which can be utilized for its biofortification. This review discuss the current scenario of micronutrient malnutrition and various strategies that could be used to overcome it. The review also shed a light on the genetic variations present in potato germplasm and suggest effective ways to incorporate them into modern high yielding potato varieties.
