Mapping the research landscape of food insecurity among tertiary education students worldwide (2002–2023): a scopus database analysis Olutosin Ademola Otekunrin, Oluwaseun Aramide Otekunrin Discover Sustainability, 2025 One of the most urgent challenges the world faces today is guaranteeing an adequate food supply for the continuously growing global population. Food insecurity (FI) is currently devastating nations globally, particularly African countries, and its impact is also affecting the population of higher education students globally. The high prevalence of FI among higher education students is currently receiving significant attention from policymakers, stakeholders, and researchers. This study aimed to conduct a bibliometric analysis of the literature on FI among higher education students. The literature search was conducted using Scopus database for articles published from 2002 to 2023. The extracted documents were analysed using the bibliometric app on R Studio and VOSviewer software. A total of 496 documents were extracted with publications annual growth rate of 21.7%. United States made the most substantial contribution in terms of the volume of publications, leading authors, collaborations, funding bodies, and institutions. University of California, United States was the most productive institution. The journal Nutrients was the most prolific and highly cited journal. The publication keywords analysis resulted in the formation of four clusters, including keywords like food insecurity, food supply, college students, mental health, COVID-19, and higher education. By providing researchers and stakeholders with a comprehensive overview of existing research on food insecurity among higher education students, this study underscores the importance of translating this knowledge into action. Specifically, it emphasizes the critical need for increased investment in research, funding, and collaboration, with a particular focus on developing countries, alongside targeted mental health support and comprehensive food programmes to effectively alleviate food insecurity.
Discrete choice modelling of hypertension patients’ preferences for attributes of a public medical facility in Ibadan, Nigeria Oluwaseun Aramide Otekunrin, Tekiyat Abiola Adebisi, Sururoh Adeniran-Babatunde, Olutosin Ademola Otekunrin BMC Health Services Research, 2025 Background Not much is known about hypertension patients’ preferences for attributes of public medical facilities in Nigeria and how these preferences influence their choices of medical facilities for treatment. An understanding of what these patients want especially in terms of service delivery could contribute to improved hypertension control. Objective This study aimed to determine hypertension patients’ preferences for attributes of a public medical facility in Ibadan, Nigeria. Methods A Discrete Choice Experiment (DCE) that utilized three hypothetical medical facilities was used for the study. A simple random sample (SRS) of 150 eligible hypertension patients was selected from a secondary medical facility in Ibadan, Nigeria. An efficient D-optimal choice design was adopted and used in generating nine hypothetical choice sets for the experiment. Each patient was expected to study the nine sets carefully and choose an option from each of the sets. The first choice set was repeated as the tenth set to examine respondents’ consistency. The DCE questionnaires were administered using a one-to-one interview method. A mixed logit regression modeling technique was used to obtain parameter and Willingness to Pay (WTP) estimates. Results The patients preferred medical facilities with waiting time before consultation with medical doctors to be between thirty minutes and one hour. The attribute level ‘‘a lot of information’’ was the most preferred. The patients were unwilling to pay for the “little or no drugs and diagnostic equipment” attribute level. A negative and significant coefficient for cost indicated that higher out-of-pocket costs negatively affected hypertension patients’ choice of a public medical facility. Conclusion Hypertension patients attending a public medical facility in Ibadan, Nigeria preferred a facility with access to comprehensive information about their health in addition to reasonable waiting times, availability of a lot of drugs and diagnostic equipment, and reduced out-of-pocket costs. Provision of healthcare services that align with these preferences could enhance patient satisfaction thus contributing to improved hypertension control.
Editorial: X-raying Zero Hunger (SDG2) targets in Africa and other regions: progress, synergies, opportunities, and challenges, volume II Olutosin Ademola Otekunrin, Mojisola Olanike Kehinde, Oluwaseun Ariyo, Barbara Sawicka Frontiers in Public Health, 2025 The report paints a concerning picture of escalating global hunger, noting that over 295 million individuals experienced acute food insecurity in the past yeara distressing trend that has continued for six consecutive years. Driven by the devastating combination of conflict, socioeconomic shocks, and environmental crises, catastrophic hunger is reaching unprecedented levels in regions spanning from Gaza and Sudan to Yemen and Mali, pushing vulnerable households to the very edge of survival. Displacement, triggered by violence and climate-related disasters, is further exacerbating the crisis, as families are uprooted from their homes and exposed to heightened risks of malnutrition and mortality. Compounding these challenges, increasingly severe climate extremes are wreaking havoc on global food systems, devastating crop yields, and disrupting critical supply chains, further jeopardizing food security for millions worldwide (1)(2)(3).Sustainable Development Goal 2 (SDG 2), also known as Zero Hunger, aims to achieve a world free from hunger by 2030. As one of the 17 SDGs, SDG 2 seeks to motivate member countries to eliminate hunger, ensure food security, improve nutrition, and promote sustainable agriculture (4-7).According to the 2022 Global Food Security Index (GFSI), seven of the top ten countries with the highest food security scores are in Europe, two are in North America (Canada and the United States), and one (Japan) is in the Asia-Pacific region. In contrast, sub-Saharan Africa faces some of the highest rates of food insecurity globally, with a significant proportion of the population unable to access nutritious diets. The percentage of people experiencing severe food insecurity in Africa increased from 17.2% in 2015 to 24.0% in 2022, exceeding the global rate of 11.8% and surpassing that of any other region (8)(9).Furthermore, data from the 2025 GRFC revealed that Nigeria (31.8 million), Sudan (25.6 million), and the Democratic Republic of the Congo (also 25.6 million) rank among the top three countries with the highest populations facing severe food insecurity in 2024 (see Figure 1). These three countries collectively account for 42% of the total population in the top ten most affected nations, highlighting that Africa bears the highest burden of global hunger and food insecurity (1). Figure 1. Top 10 countries with the highest number of population facing severe food insecurity in 2024 Source: Authors' compilation using 2025 GRFC (FSIN, 2025) Gujo and Modiba investigated food insecurity in the South Omo Zone of Southern Ethiopia, focusing on pastoralist and agrarian communities. Despite existing interventions, food insecurity remained a significant issue with limited data specific to the region. The study aimed to determine the prevalence of food insecurity and identified contributing factors. A cross-sectional study was conducted with 597 participants from randomly selected households. The Household Food Insecurity Access Scale (HFIAS) was used for measurement, and data were analysed using SPSS V25. Binary logistic regression identified factors linked to food insecurity (p<0.05).The study found that 42.2% of households experienced food insecurity, with varying severity levels. Key factors impacting food security included female-headed households, high dependency ratios, lack of maternal education, absence of participation in safety net programs, and lack of land ownership. These findings highlight the need for targeted interventions in the South Omo Zone. The study recommends improving female education, advancing agricultural techniques, promoting family planning, and expanding safety net programs to enhance food security and community well-being.Tamir et al.'s study, titled "Spatial heterogeneity and predictors of stunting among under five children in Mozambique: a geographically weighted regression," examines the spatial variations and predictors of stunting in Mozambican children under five, using Geographically Weighted Regression (GWR) to account for localized relationships. The study included a sample of 3,910 under-five children. Data from the 2011 Mozambique Demographic and Health Survey (DHS) were analysed, incorporating variables like household wealth, maternal education, sanitation access, and healthcare access. GWR's performance was compared to Ordinary Least Squares (OLS) regression, highlighting the benefits of considering spatial heterogeneity. The analysis pinpointed areas where specific predictors, like maternal education and sanitation, had a stronger influence on stunting. The findings revealed significant spatial variations in stunting predictors across Mozambique. The impact of maternal education and sanitation access varied geographically, emphasizing the importance of local context in intervention design. The study concludes that geographically targeted interventions, informed by GWR-identified spatial patterns, are more likely to effectively reduce stunting among under-five children in Mozambique.Adugna et al.'s explores the nutritional well-being of 309 school children (6-14 years old) in Addis Ababa, Ethiopia, considering socioeconomic, environmental, and behavioural influences. Acknowledging that poor nutrition impacts development and learning, the research sought to pinpoint key factors to guide effective interventions. The study offers valuable insights into the multifaceted influences on child nutrition within an urban environment. To achieve this, data was gathered on height and weight, household socioeconomic status, environmental conditions like sanitation and water access, and behaviours including diet and physical activity. Statistical analyses determined the prevalence of undernutrition (stunting, underweight, thinness) and identified significant predictive factors.The results indicated a notable prevalence of suboptimal nutrition among Addis Ababa's school children. Key predictors of undernutrition included low socioeconomic status, inadequate sanitation and clean water, poor dietary diversity, and limited physical activity. The study emphasizes the necessity of comprehensive, multi-sectoral interventions addressing socioeconomic and environmental factors, alongside promoting healthy eating and active lifestyles.Beni et al. explores quantile regression to pinpoint the key factors driving malnutrition in Gabon, Gambia, Liberia, Mauritania, and Nigeria. Recognizing that these factors may impact children differently depending on their nutritional status, the researchers analysed influences across the spectrum of malnutrition, rather than just looking at average effects. This provides a more detailed understanding of the complex causes of malnutrition in the region. Data from Demographic and Health Surveys (DHS) in these five countries were analysed, focusing on under-five children. The study examined socioeconomic, demographic, and health variables as potential drivers of malnutrition, measured by stunting, wasting, and underweight. Quantile regression models estimated the impact of these variables at different points (quantiles) of the malnutrition indicators.The results showed that the drivers of malnutrition varied significantly across different nutritional status levels. For instance, maternal education and household wealth had a greater impact on improving nutrition for children with the poorest nutritional status compared to those already better nourished. The study emphasizes the need for customized interventions that address the specific needs of children at different levels of malnutrition and concludes that quantile regression is a useful tool for identifying effective, targeted strategies to fight malnutrition in West Africa.Endawkie et al.'s study investigates disparities in inadequate minimum dietary diversity (MDD) between poor and non-poor children aged 6 to 23 months in Sub-Saharan Africa. Recognising that adequate dietary diversity is essential for proper growth and development, the researchers aimed to identify factors contributing to the MDD gap between these groups. They employed multivariate decomposition analysis to assess the influence of various socioeconomic and demographic factors on this disparity. Data from DHS conducted across multiple Sub-Saharan African countries were analysed, focusing on children aged 6 to 23 months. Key variables included household wealth, maternal education, access to healthcare, and geographic location. This decomposition method quantified how much these factors explain the observed differences in inadequate MDD between poor and non-poor children.The findings revealed a significant disparity in inadequate MDD, with poor children disproportionately affected. The analysis identified household wealth, maternal education, and healthcare access as major contributors to this gap. The study underscores the need for targeted interventions addressing these socioeconomic inequalities to improve dietary diversity and nutritional outcomes for all children, especially those from disadvantaged backgrounds.Gashe et al.'s study titled "Investigating a severe acute malnutrition outbreak in Dubti District, Awsiresu Zone, Afar Region, Northeast Ethiopia (2022)" examines the causes and factors contributing to a severe acute malnutrition (SAM) outbreak in the Dubti District of Northeast Ethiopia. The study investigates the epidemiology of the outbreak, identifies key risk factors, and assesses the affected population's characteristics. By analysing data collected during the 2022 outbreak, the researchers aimed to understand the underlying drivers such as food insecurity, inadequate healthcare access, poor sanitation, and socio-economic conditions. The findings highlight critical gaps in nutrition and public health interventions in the region, emphasizing the need for targeted strategies to prevent future outbreaks. The study calls for strengthened community-based nutrition programmes, improved healthcare delivery, and multisectoral collaboration to address the root causes of malnutrition in this vulnerable population.Tebeje et al.'s study, titled "Minimum meal frequency and associated factors among children aged 6-23 months in Sub-Saharan Africa: a multilevel analysis of the demographic and health survey data," examines the prevalence of minimum meal frequency (MMF) among young children in Sub-Saharan Africa and the factors that influence it. Using data from DHS across multiple countries, the study employs multilevel analysis to explore individual, household, and community-level determinants affecting whether children aged 6 to 23 months receive the recommended minimum number of meals per day. The findings reveal significant regional variations in MMF and identify key predictors such as maternal education, household wealth, access to healthcare, and rural versus urban residence. The study emphasises the need for targeted nutrition interventions and policies addressing these factors to improve feeding practices and ultimately enhance child health and development across Sub-Saharan Africa.Tareke et al.'s article titled "Identifying high-risk population segments for underweight, overweight, and obesity among reproductive-age women in sub-Saharan Africa" explores the dual burden of malnutrition among 247,911 reproductive-age women aged 15-49 in 33 sub-Saharan African countries. Using DHS data, the study reports that 11% of women are underweight, 18% overweight, and 10% obese. These findings highlight the complex and shifting nature of nutritional challenges in the region. The study identifies underweight as more common among younger, poorer, rural women with limited education or media exposure. Conversely, overweight and obesity are linked to older age, urban residence, and higher socioeconomic status, use of modern contraceptives, higher parity, and lack of breastfeeding. Employment appears to offer protection across all malnutrition categories, suggesting economic empowerment may enhance health outcomes.The authors recommend targeted public health strategies: addressing undernutrition among younger, rural, and low-income women, and focusing obesity and overweight interventions on older, wealthier, urban populations-particularly in southern and central Africa. The study emphasizes the need for region-specific, socially informed nutrition policies to combat malnutrition's contrasting trends.The work of Eyasu et al. titled "Impact of crop commercialization on multidimensional poverty in rural Ethiopia: propensity score approach" examines how market-oriented crop production influences rural household well-being. Using data from the 2018/19 Ethiopian Socioeconomic Survey, the study analysed 2,714 rural households across 59 administrative zones. The researchers constructed a Rural Multidimensional Poverty Index (R-MPI) based on five key dimensions: nutrition & health, education, living standards, rural livelihoods, and risk exposure. They employed a generalized linear mixed-effects model and propensity score methods to assess the causal relationship between crop commercialization and multidimensional poverty. Findings reveal that 47.8% of rural households were multidimensionally poor, with the highest deprivation occurring in living standards and nutrition. Spatial disparities were evident, with poverty concentrated in zones like Shebelle, Konso, and regions such as Afar and Somali. Importantly, households engaged in crop commercialization were significantly less likely to experience multidimensional poverty. The odds of being multidimensionally poor were reduced by approximately 21% among commercializing households compared to their subsistence counterparts.The study concludes that crop commercialization is a vital pathway to reducing multidimensional poverty in rural Ethiopia. To maximize its benefits, the authors recommend targeted policies that support smallholder market access, infrastructure development, and region-specific interventions. Tackling spatial poverty hotspots is essential for inclusive and sustainable rural development.This Research Topic brings together nine scholarly articles that collectively address a vital and underexplored area in the existing literature: the global fight against hunger, with a dedicated focus on the African continent. These articles provide an in-depth examination of the progress made so far, critically assessing where efforts have succeeded and where significant gaps remain. A central theme running through the collection is the interplay between Sustainable Development Goal 2 (Zero Hunger) and other interconnected SDGs-such as poverty reduction, health, climate action, and sustainable agriculture-underscoring the need for integrated, cross-sectoral strategies. The research further unpacks the specific challenges faced by African nations, including food system vulnerabilities, policy implementation barriers, limited financing, and institutional weaknesses. At the same time, it explores the opportunities presented by innovation, regional cooperation, and targeted social protection
Assessing the Prevalence and Severity of Global Hunger and Food Insecurity: Recent Dynamics and Sub-Saharan Africa’s Burden Olutosin Ademola Otekunrin Sustainability Switzerland, 2024 One of today’s most critical challenges is ensuring sufficient and safe food production and supply for the ever-expanding global population. Recently, many countries around the world, particularly those in Africa, have been grappling with severe hunger and food insecurity, frequently exacerbated by events such as escalating global prices, persistent insecurity, and the repercussions of the COVID-19 pandemic. This study undertook an extensive review of the prevalence and severity of hunger and food insecurity across diverse countries and regions. The review utilised several metrics, including Global Hunger Index (GHI) scores, Global Food Security Index (GFSI) scores, 2015–2022 data (related to two Sustainable Development Goal 2 (SDG2) targets) from the Food and Agriculture Organization (FAO), and other pertinent sources to assess the development of the current status of the countries included in this study. The 20 countries with 2023 GHI scores below five were collectively ranked from 1 to 20, signifying low hunger levels. However, the Central African Republic (CAR) received the lowest ranking, at 125 out of 125, with a score of 42.3, indicating an alarming level of hunger. Finland achieved the highest GFSI score of 83.7, with Oman showing the most notable GFSI improvement at +13.8, while Syria experienced a significant decline in the GFSI score by −10.5. Over time, many countries, particularly the developed ones, have witnessed significant improvements in their GHI and GFSI scores. Meanwhile, most countries in sub-Saharan Africa have experienced the greatest deterioration in their GFSI scores and notable increases in their GHI scores. The review documented the significant progress made by countries and regions in reducing levels of hunger and food insecurity while highlighting the substantial burden borne by sub-Saharan Africa (SSA) in combating global hunger and food insecurity.
Adoption of biogas technology by cassava processors: Implication for environmental sustainability Ridwan Mukaila, Ibrahim Isaac Umaru, Olutosin Ademola Otekunrin, Emmanuel Ejiofor Omeje, Festus EluwandeDurojaye Awoyelu, Ogochukwu Gabriela Onah, Oguejiofor Joseph Okorie, Chukwuemeka Chiebonam Onyia, Goodness Somukenechukwu Ezinwa World Development Sustainability, 2024 Improved and environmentally friendly agricultural waste management technology is needed to improve the environment and avoid some health issues as a result of poor waste management. Yet, its adoption is low and there is little documented work on the subject matter, especially in Nigeria. Therefore, this study assessed cassava processors’ willingness to adopt improved cassava waste management technology in Nigeria. Descriptive statistics and logistic regression were used to analyse data collected from 240 cassava processors using a structured questionnaire. The current cassava waste management practices among the processors were disposing of the solid waste through open dumping around the processing site, letting liquid waste run off and dry on the ground, channelling liquid waste to the drainage system, burning waste and disposing of waste on the farm. These methods caused insects and pests to breed and bad odour in the area, which resulted in an unhealthy environment and affected people's health. Awareness of biogas technology for cassava waste management was very low (21.25%) among the processors and only 10.83% were aware of its benefits. However, 74.17% were willing to adopt biogas technology to manage waste after the creation of awareness about biogas technology. The significant factors responsible for their intention to adopt improved technology were awareness of biogas technology, awareness of the benefits of biogas technology, age, experience, extension services, access to credit, and membership in an association. This study advocates the creation of awareness about modern improved waste management by institutions, and agricultural extension to have a healthy environment.
Editorial: X-raying zero hunger (SDG2) targets in Africa and other regions: progress, synergies, opportunities, and challenges Olutosin Ademola Otekunrin, Mojisola Olanike Kehinde, Oluwaseun Ariyo, Barbara Sawicka Frontiers in Public Health, 2024 1. IntroductionFeeding a global population exceeding 8 billion people poses a monumental challenge, particularly for developing nations. The 2024 State of Food Security and Nutrition (SOFI) report paints a sobering picture: between 713 and 757 million individuals experienced hunger in 2023 – a staggering one in eleven individuals worldwide, and one in five in Africa alone (1). This translates to a staggering 28.9% of the global population, or 2.33 billion people, facing moderate or severe food insecurity (1).The convergence of the COVID-19 pandemic, the Russia-Ukraine conflict, climate change, poverty, growing inequalities, and soaring food prices has fuelled a global hunger crisis, with Africa bearing the brunt. Africa faces the highest rate of hunger, with 20.4% of its population affected, compared to 8.1% in Asia, 6.2% in Latin America and the Caribbean, and 7.3% in Oceania (1-3). By 2030, an estimated 582 million people will be chronically undernourished, over half residing in Africa (1). Furthermore, both South Asia and sub-Saharan Africa recorded the highest hunger levels in 2023, with a Global Hunger Index (GHI) score of 27.0 each, highlighting the significant prevalence of hunger in these regions (3-4)Despite these grim realities, the United Nations (UN) remains committed to ending hunger through Sustainable Development Goal 2 (SDG 2), also known as Zero Hunger. This ambitious goal aims to "end hunger, achieve food security and improved nutrition, and promote sustainable agriculture" by 2030 (5). Since its launch in 2015, many nations have implemented food and nutrition-sensitive policies aimed at achieving this goal. However, persistent challenges, including poverty, population growth, conflict, and climate change, have hindered progress, particularly in Africa (6-7).This Research Topic aims to assess progress made in combating hunger globally, analyse the interconnectedness between SDG 2 (Zero Hunger) and other SDGs, and explore the potential opportunities and challenges facing Africa and other regions in achieving SDG2 by 2030. The study will delve into the SDG2 plans and programmes of African nations and other countries, examining their implementation of the five key SDG 2 targets (UN, 2017). The following section introduces the articles included in this Research Topic. The paper concludes with a summary of the key findings and overall insights.2. Articles in the Research TopicThis Research Topic (RT) presents eight articles (six original research articles, one study protocol, and one review article) that have successfully undergone rigorous peer review, meeting the high standards of Frontiers in Public Health. While these articles explore diverse topics, theoretical perspectives, and methodologies, they are all connected to the overarching themes of this RT. Despite numerous interventions aimed at promoting healthy diets and reducing food insecurity, limited research exists on the consumption patterns that contribute to achieving healthy diets and zero hunger within households, particularly the budget allocation towards specific food items. Ogunleke et al. investigated these patterns among 600 rice-consuming households in South-West Nigeria (Lagos, Osun, and Ogun states) using primary data. Their study revealed that rice, particularly local (Ofada) rice, is the most consumed food item in the region, accounting for a significant 0.195 of the monthly household budget. Employing a linear approximated QUAIDS model, the study analysed household demand for local rice in the South-West region. Findings indicate that local rice consumption is substantial in this region and that local rice is not considered a luxury good based on the calculated expenditure elasticities, all of which are expenditure inelastic.Adeyemo and Adeagbo's Nigerian study examined the impact of land reforms on smallholder farmers. The research utilized data from the 2018/2019 Living Standard Survey Integrated Survey on Agriculture (LSMS/ISA) involving 4,032 respondents. The findings showed that despite low land titling rates (around 12%), land titles had a significant positive impact on agricultural production. Households with land titles also had significantly higher food expenditures (N9,868) compared to those without titles (N6,172). The study concluded that implementing and expanding formal land registration and titling could be a critical step towards achieving food security goals in Nigeria.Despite ongoing efforts, the global hunger crisis continues to worsen. Adding to this challenge is the widespread issue of food waste, which disrupts food supply chains and negatively impacts the environment due to inefficient waste management. Zaini et al.'s review article identifies key waste streams generated during the production of mushroom, peanut, and soybean (MPS). Mushroom, with its functional and nutraceutical properties, is increasingly recognized as a future food source. Peanuts, known for their rich nutritional value, are consumed globally and are a staple ingredient in many cuisines. Soybean, a significant plant-based protein source, is widely cultivated and consumed worldwide, particularly in Asia (8). The article highlights the critical potential of MPS as future foods in the fight against hunger, while also acknowledging the challenges that need to be addressed. Sawadogo et al. examined the factors contributing to the decline in chronic malnutrition in Burkina Faso during the 2000s, a period marked by increased access to healthcare services. Utilizing data from Demographic and Health Surveys (DHS) conducted in 2003 and 2010, the study analysed the temporal variations in chronic malnutrition using the Oaxaca-Blinder multivariate decomposition method. Their findings revealed that improved access to healthcare services significantly contributed to the reduction of chronic malnutrition between 2003 and 2010. The study emphasises the critical importance of ensuring access to healthcare services for children as a cornerstone of any programmes aimed at tackling child malnutrition.Child and maternal malnutrition (CMM) remains a major global health challenge, contributing significantly to disability-adjusted life years (DALYs) and deaths. Liu et al., in a comprehensive analysis using data from the Global Burden of Disease study 2019 (GBD 2019), examined the global impact of CMM from 1990 to 2019. Their findings revealed a substantial burden, particularly affecting infants under 28 days old, with sub-Saharan Africa experiencing the most significant impact. Globally, low birth weight and short gestation were identified as primary risk factors for CMM. The study highlights the crucial influence of national economic levels, healthcare expenditures, and the allocation of medical resources on the disease burden associated with CMM.Anaemia remains a significant health concern among women of reproductive age in sub-Saharan Africa. Tirore et al. examined the prevalence and severity of anaemia in 21 countries using recent Demographic and Health Survey (DHS) data from 2015 to 2022. Their analysis of 171,348 women revealed a concerning prevalence of anaemia at 41.74%. The study identified several factors contributing to higher anaemia risk, including distance from healthcare facilities, poverty, lack of improved sanitation, and the use of solid cooking fuel. The researchers emphasize the crucial need to integrate women's empowerment, through education and economic opportunities, into anaemia prevention and control programmes across Africa. Downs et al. have designed a study protocol to evaluate the efficacy of mHealth interventions in promoting recommended behaviour change communication (BCC) strategies among caregivers of infants and young children in Senegal. The trial will take place in three regions (Thies, Fatick, Diourbel) and involve 488 mother-father-child triads, with children aged 6 to 23 months. The primary outcomes of interest are minimal acceptable diet (MAD) and anaemia. The study will gather qualitative data through focus group discussions with mothers and fathers and semi-structured interviews with Badienou Gox and national partners and program implementers to assess the intervention's implementation process.Undernutrition remains a major health concern in many developing countries, particularly affecting children in Africa, especially in Ethiopia. Yitayew et al. investigated the prevalence of acute malnutrition relapse among under-five children in Northeast Ethiopia. Their study, involving 318 children who had been enrolled and discharged from a community-based acute malnutrition management programme, revealed an alarming 35.2% relapse rate after discharge. The researchers emphasize the critical need for comprehensive health education and counselling services to improve maternal knowledge and practices, focusing on child immunization and hygiene maintenance to prevent diarrheal diseases, which can significantly contribute to reducing the risk of malnutrition relapse.3. ConclusionThis Research Topic brought together eight articles that collectively address a critical gap in the literature by exploring global progress in combating hunger, with a particular focus on the African region. The articles analyse the interlinkages between SDG 2 (Zero Hunger) and other Sustainable Development Goals, while also examining the opportunities and challenges facing African nations and other regions in achieving Zero Hunger by 2030. The research delves into the implementation of relevant plans and programmes, offering valuable insights into the complex challenges and potential solutions in the pursuit of a hunger-free world.Author ContributionAll listed authors have made substantial, direct, and intellectual contributions to this work and have jointly approved it for publication.FundingThis research received no external funding.Data Availability StatementNot ApplicableConflict of interestThe authors declare no conflicts of interest.Ethical approval and Consent to ParticipateNot Applicable
Countdown to The 2030 Global Goals: A Bibliometric Analysis of Research Trends on SDG 2-Zero Hunger Olutosin Ademola Otekunrin Current Research in Nutrition and Food Science, 2023 As we approach the deadline for achieving the United Nations’ 17 Sustainable Development Goals (SDGs), which is less than a decade away, it is crucial for researchers and research institutions at both national and international levels to conduct rigorous scientific assessments of the progress made towards these goals. The assessment is of utmost importance as it will provide valuable insights and information to political leaders and other stakeholders, guiding their actions and efforts towards successfully attaining the SDGs by the year 2030. This study aimed at providing vivid descriptions of the SDG 2 – zero hunger-related research endeavour. It employed bibliometric analysis and geographical patterns of SDG 2-related publications extracted from Scopus database from 2015 to 2023. A total of 397 documents were extracted where Sustainability journal ranked 1st among the journal outlets of zero hunger-related publications. The publication of zero hunger-related documents grew from 1.5% in 2016 to 29.7% in 2022. Food and Agriculture Organisation (FAO) and Chinese Academy of Sciences were the top 2 institutions publishing zero hunger-related documents while the lead article was published by Journal of Cleaner Production with 128 citations. The funding sponsors of SDG 2-related publications were dominated by sponsors from developed countries (such as China, Belgium, United States, and United Kingdom) while no funding sponsors from developing countries were among the top 10. The United States and United Kingdom were the two most productive countries while only one African country (South Africa) made the list of top 10 countries publishing zero hunger-related documents. This study provided political leaders and key stakeholders with in-depth understanding of the SDG 2-related research activities and highlighted research funding and collaboration gaps facing the developing nations.
Dietary diversity, nutritional status, and agricultural commercialization: evidence from adult men of rural farm households Olutosin Ademola Otekunrin, Idris Akanbi Ayinde, Rahman Akintayo Sanusi, Oluseye Olusegun Onabanjo Dialogues in Health, 2023 Access to healthy and affordable diet hinged on the realization of Sustainable Development Goal 2, higher productivity and, economic prosperity while it is difficult for a poorly nourished people to achieve optimum production of goods and services. This study assessed whether dietary diversity (DD) and nutritional status of adult men are associated with crop commercialization index (CCI) levels of agricultural households in two states of Southwestern Nigeria. This research utilized 352 farm households, comprising 277 adult male members. The individual version of dietary diversity score (DDS) of 9 food groups was used to calculate adult men's DDS over a 24-h recall. Anthropometric data was obtained using body mass index (BMI) while CCI levels was estimated for each agricultural household. Logistic regression and ordered logit models were used to examine the determinants of adult men's dietary diversity and nutritional status respectively. Hundred percent of adult men consumed starchy staples, with 11.2% consuming egg, 5.8% milk and milk products and 0.4% consuming organ meat over 24-h recall. Adult men of CCI 2 and CCI 4 agricultural households recorded overweight prevalence of >20% in Ogun state while the association between DDS and CCI was statistically insignificant suggesting that being a member of any of the CCI households may not guarantee the consumption of healthy diets among adult men. From Logit regression analysis, it is more likely for adult men with higher farm size to attain the minimum DDS of 4 food groups than those with smaller size of farmland (OR = 4.78; 95% CI: 1.94, 11.76; p = 0.001). The age, farm experience, and cassava marketing experience were positively related to the likelihood of obtaining the minimum DDS. For adult men to achieve a healthy diet, their diet pattern must incorporate a more diversified intake of food from different food groups capable of improving their nutritional status. This study emphasized the need for relevant stakeholders to provide adequate nutrition knowledge intervention programmes capable of improving the diets and nutrition of adult men and other members of farm households.
