North Africa faces significant challenges of food insecurity and environmental degradation, driven by rapid population growth, ongoing droughts, severe water stress, and increasing rates of undernourishment. Achieving food security and environmental sustainability requires a balanced evaluation of agricultural productivity, resource efficiency, ecosystem health, and climate resilience. Therefore, this study develops a composite food security and environmental sustainability index (FSESI) that encompasses complex relationships via multidimensional indicators. Data analysis was conducted for Egypt, Libya, Algeria, Tunisia, Morocco, Sudan, and Mauritania, covering the period from 2010 to 2022. A comprehensive methodology employing data envelopment analysis (DEA) for objective weighting and geometric mean aggregation was implemented. The findings indicate notable disparities; Sudan presented the highest undernourishment rate (21.8% in 2010, 11.4% in 2022), whereas Libya faced severe water stress (783.12% to 817.14%). Morocco recorded the highest FSESI score of 0.78, reflecting strong performance in both the food security and environmental dimensions, whereas Algeria and Libya each had scores of 0.48, indicating relatively modest outcomes. Finally, sensitivity analysis was employed to check the robustness of the results. This research highlights the need for immediate policy actions focused on equitable resource management, enhanced agricultural methods, and reinforced food security initiatives. This study directly supports Sustainable Development Goal (SDG) 2, Zero Hunger; SDG 6, Clean Water and Sanitation; SDG 13, Climate Action; and SDG 15, Life on Land, by addressing integrated challenges in food security and environmental sustainability in North Africa. The originality of this work lies in its thorough integration of environmental and food security dimensions through innovative aggregation methods, offering a replicable framework that policymakers and researchers can use to address complex environmental and food security issues in North Africa sustainably.

Objectives: To describe the results of nutritional and morphofunctional assessment in a cohort of adults with cystic fibrosis; to evaluate differences in nutritional status between patients with and without exocrine and/or endocrine pancreatic involvement. Methods: Cross-sectional study: A cohort of adults with cystic fibrosis evaluated in a multidisciplinary unit was analyzed. Pancreatic status was examined, and malnutrition was diagnosed according to GLIM criteria. Morphofunctional assessment consisted of nutritional ultrasound, bioelectrical impedance, handgrip dynamometry, and anthropometry. Qualitative variables are expressed as n (%), quantitative variables as median (IQR). For group comparisons, Fisher’s exact test was used for qualitative variables and the non-parametric median comparison test for quantitative variables. Results: n = 101 participants were recruited, of whom 44 (43.6%) were women. Median age was 33 (25–40.5) years. A total of 64 participants (63.4%) had exocrine pancreatic insufficiency (EPI), 44 (43.6%) had endocrine pancreatic insufficiency, and 28 (27.7%) had cystic fibrosis-related diabetes (CFRD). Median BMI was 23.4 (20.1–24.89) kg/m². A total of 48 patients (47.5%) were malnourished. Males with EPI had a higher prevalence of undernourishment than those without (56.4% vs. 16.7%, p = 0.005), but not women. CFRD patients displayed no differences in morphofunctional assessment. Conclusions: Almost half the sample was undernourished using GLIM criteria. Males with exocrine pancreatic insufficiency had worse nutritional status. Endocrine pancreatic involvement did not affect nutritional status. Full article

Background: Food neophobia, defined as reluctance to try new foods, may lead to nutritional deficiencies and complicate dietary management—especially in individuals with Down syndrome, who often present with oral-motor dysfunction. This condition may result in nutritional deficiencies and difficulties in adhering to dietary recommendations, particularly in individuals with comorbidities. In individuals with Down syndrome (DS), who frequently present with oral motor disorders and chronic diseases, the problem may be especially pronounced. Objectives: The aim of the study was to assess the risk of food neophobia and feeding difficulties in children, adolescents, and young adults with Down syndrome, as well as their associations with age, gender, and body weight. Methods: The research was conducted using the CAWI method among 310 caregivers of individuals with DS in Poland. Two validated tools were employed: the Montreal Children’s Hospital Feeding Scale (MCH-FS) and the Food Neophobia Scale for Children (FNSC). Body mass index (BMI), comorbidities, and demographic data were also analyzed. Results: Findings revealed that the majority of participants (55.2%) had normal body weight, while 19.4% were undernourished and 6.5% were classified as obese. Feeding difficulties of moderate to very high severity were reported in 26.5% of the participants. A high risk of food neophobia was identified in 41.3% of respondents, most frequently in the preschool age group. A statistically significant association was observed between age and the severity of both feeding difficulties and neophobia (p < 0.05). However, no significant relationships were found with gender or body weight. Conclusions: Feeding difficulties and food neophobia are prevalent among individuals with Down syndrome, particularly in preschool-aged children. The findings highlight the necessity of an interdisciplinary therapeutic approach and the individualization of dietary interventions, taking developmental age into account. Further studies are warranted, with consideration of environmental and psychosocial factors. Full article

The COVID-19 pandemic intensified existing structural challenges in Africa, including poverty, weak healthcare systems, and fragile agricultural supply chains. Consequently, examining its effects remains a critical area of study. This research investigates the effect of food prices on the prevalence of malnutrition in the context of the COVID-19 pandemic in sub-Saharan Africa. The findings indicate a significant long-term relationship between the number of COVID-19 cases, food prices, and the prevalence of undernourishment. Specifically, increases in food prices are associated with a rise in undernourishment rates over the long term. These results are corroborated by estimations using Fully Modified Ordinary Least Squares (FMOLS). To mitigate malnutrition in the face of potential future health shocks, governments could create and operationalize food price stabilization funds to cushion against sharp increases in food prices. These funds can be used to subsidize key staples during periods of price volatility, ensuring affordability for vulnerable populations. Full article

Background: Nearly half of under-five deaths are linked to undernutrition. Most evidence on undernutrition relies on conventional anthropometric measures. Conventional anthropometric measures fail to capture its overlapping forms and are limited in providing the true burden and distinct disaggregated patterns of undernutrition. Using the Composite Index of Anthropometric Failure (CIAF), this study aims to provide updated regional and country-level pooled prevalence estimates of the overall burden and various single and coexisting patterns of undernutrition among children in Sub-Saharan Africa (SSA). Methods: We systematically searched Medline, CINAHL, Web of Science, Scopus, and Google Scholar for studies published between January 2006 and October 2023. Studies reporting the prevalence of aggregated CIAF or any of the disaggregated forms of CIAF (stunting only, wasting only, underweight only, stunting-underweight, wasting-underweight, and stunting-wasting-underweight) based on the 2006 World Health Organisation (WHO) growth standard were included. Data extraction was performed by two reviewers, and discrepancies were resolved by consensus. Pooled prevalences of various categories of undernutrition were estimated using a random effect model meta-analysis. Subgroup analysis and meta-regression were performed to identify possible sources of heterogeneity among the included studies. Publication bias was checked using the Asymmetry funnel plot and Egger’s test. The protocol was registered on PROSPERO (CRD42023458796). Result: This systematic review and meta-analysis identified 3898 published studies from the database search, of which 26 were included. In SSA, the overall pooled prevalence of undernutrition among children was 37.45% (95% Confidence Interval (CI): 31.97, 42.92). Of these, 10% (95% CI: 8.02, 11.98) of children experienced at least one coexisting form, and 25.5% (95% CI: 16.78, 33.72) experienced at least one single form of undernutrition. Stunting only [22.32% (95% CI: 18.26, 26.39)] was the most prevalent disaggregated pattern of undernutrition, followed by the coexistence of stunting with underweight [10.15% (95% CI: 8.17, 12.13)]. Conclusions: Over one in three children in SSA experienced at least one form of undernutrition. Nearly one-third of these undernourished children were affected by multiple forms of undernutrition. The high prevalence of coexisting undernutrition indicates the need to develop multi-indicator nutrition strategies that could simultaneously address the various dimensions of undernutrition in children.

Background/Introduction: Undernutrition’s impact on healthcare utilisation across age groups and care settings remains underexplored, particularly in Asian contexts. This study investigated the dynamic association between nutritional status and healthcare utilisation among community-dwelling adults in Singapore and assessed whether age modified this relationship. Methods: The study sampled 1703 adults enrolled in the Population Health Index study. Nutritional status was assessed annually using the Mini Nutritional Assessment, and healthcare utilisation data—across primary care, specialist outpatient clinics (SOCs), emergency departments (EDs), day surgeries, and inpatient admissions—were extracted from administrative databases. Negative binomial regressions with interaction terms using longitudinal panel data were conducted to examine age-modified effects. Results: At baseline, 9.7% of participants were classified as undernourished, with a higher prevalence in older adults (15.0%). Key risk factors for undernutrition included female sex, unemployment, financial inadequacy, currently smoking, lack of formal education, and multimorbidity. Undernutrition was associated with increased ED visits (IRR 1.41, AME: 0.35) and inpatient admissions (IRR 1.52, AME: 0.42). Among older adults, undernutrition was associated with less primary and specialist care (IRR: 0.72 and 0.57), while younger undernourished adults had more SOC visits (AME: 0.46). Older undernourished adults had 0.46 more ED visits and 0.47 more inpatient admissions on average in one year, though these increases did not differ from younger adults (interaction p > 0.05). Conclusions: Undernutrition is associated with increased ED visits and inpatient admissions, especially in older adults. Integrating nutritional screening and targeted interventions into community and primary care may help reduce preventable hospitalisations in high-risk populations. Full article

Background: Malnutrition may increase the risk of frailty in individuals with musculoskeletal pain. However, this scenario has not been explored in detail. As such, the present study was conducted to examine the effects of malnutrition on the risk of incident and worsening frailty in community-dwelling older adults with musculoskeletal pain. Methods: Data from 895 community-dwelling older adults participating in the Toledo Study of Healthy Ageing who reported experiencing musculoskeletal pain during the month preceding data collection (mean age: 74.9 ± 5.6 years) were analyzed. Pain characteristics (i.e., intensity, locations, and treatment) were assessed based on self-reported information regarding the last month. Malnutrition was operationalized according to the GLIM criteria. Frailty status was assessed at baseline and at follow-up (~2.99 years), according to the Frailty Phenotype paradigm, operationalized through the Frailty Trait Scale 5. Associations between the variables were tested using logistic regression analyses adjusted for many covariates established a priori. Results: Malnutrition increased the risk of frailty (odds ratio [OR] = 4.41) and worsening of frailty status (OR = 6.25) in the participants who used ≥2 groups of painkillers in comparison to their non-undernourished peers. Conclusions: The findings of the present study indicate that malnutrition increases the risk of both developing and worsening frailty in older adults with musculoskeletal disorders. In particular, an increased risk of incident frailty and worsening frailty status was found in undernourished individuals using ≥2 analgesic drugs. Our results suggest that nutritional assessment should be included in the evaluation of old people living with musculoskeletal pain. Full article

The developmental origins of adult disease theory support the concept that undernourished fetuses are at risk of developing metabolic syndrome due to the energy-saving ‘Thrifty Phenotype’. This metabolic plasticity represents an evolutionary adaptation that allows individuals to resist the intense pressure caused by cyclically recurring periods of nutritional deprivation. A comprehensive review was conducted following an extensive literature search in the PubMed/Medline and EMBASE databases concerning reports on fetal/intrauterine growth restriction and its metabolic-related long-term outcomes. We only included articles written in English that were published before 1 July 2024. There are several underlying mechanisms and metabolic and endocrine adjustments shaped by the perinatal environment, and they all contribute to progression towards adult disease. From in utero malnutrition or other insults during the fetal period to fetal programing and postnatal catch-up growth, it is difficult to identify the exact moment when this adaptative phenomenon meant to assure fetal survival and to set children on their own physiological growth curves lose its beneficial effect, establishing the trajectory to obesity, insulin resistance, and other hallmarks of metabolic syndrome. With clinical correspondence to an altered body mass, composition, and eating behaviors, it is evident that the metabolic complications linked to FGR are intricate and arise from disturbances in several pathways and organs, but the underlying processes responsible for the long-term consequences are just starting to be understood. The lack of continuity in perinatal-to-pediatric FGR research sets the challenge of exploring new directions in future scientific opportunities. These will hopefully represent a cornerstone in the management of FGR-related metabolic disorders in children, preventing these disorders from evolving into adult disease. Full article

Background: Malnutrition is highly prevalent in patients with head and neck cancer, with relevant consequences in the treatment results. Methods: Multicenter observational study including 514 patients diagnosed with HNC. The morphofunctional assessment was carried out during the first 2 weeks of radiotherapy treatment. A correlation analysis between nutritional variables and groups of malnutrition, a multivariate logistic regression analysis, and a random forest analysis to select the most relevant variables to predict malnutrition were performed. Results: In total, 51.6% were undernourished (26.3% moderately and 25.3% severely). There was a negative correlation between morphofunctional variables and a positive correlation between hsCRP and well vs. moderate and well vs. severe malnutrition groups. The increase in different bioelectrical and ultrasound parameters was associated with a lower risk of moderate and severe malnutrition when groups with different degrees of malnutrition were compared. To predict the importance of morphofunctional variables on the risk of undernutrition, a nomogram, a random forest, and decision tree models were conducted. For the well vs. moderate, for the well vs. severe, and for the moderate vs. severe malnutrition groups, FFMI (cut-off < 20 kg/m²), BCMI (cut-off < 7.6 kg/m²), and RF-Y-axis (cut-off < 0.94 cm), respectively, were the most crucial variables, showing a greater probability of mortality in the two last comparisons. Conclusions: Malnutrition is very prevalent in HNC patients. Morphofunctional assessment with simple tools such as electrical impedance and muscle ultrasound allows an early nutritional diagnosis with an impact on survival. Therefore, these techniques should be incorporated into the daily clinical attention of patients with HNC. Full article

To the best of our knowledge, no studies in the literature have reported on the relationship between the pregnancy-associated glycoprotein (PAG) concentration and undernutrition during pregnancy in sheep. Therefore, the aim of this study was to investigate the effects of undernutrition on the blood concentration of PAGs in pregnant ewes carrying single and multiple fetuses, undergoing either dietary energy restriction or receiving 100% of their energy requirements during the period of maximal placenta growth. From d 24 to 100 of pregnancy, the ewes were fed ryegrass hay and two different iso-proteic concentrates, fulfilling either 100% of the ewes’ energy requirements (control group; n = 30, 14 singleton pregnancies, 16 multiple pregnancies) or only 50% (feed-restricted group; n = 29; 11 singleton pregnancies, 18 multiple pregnancies). Blood samples were collected from all the ewes the day before intravaginal sponge insertion (T0) and, thereafter, every 30 days starting from d 24 of gestation (T1) until d 30 after parturition (T6), to determine the PAG, progesterone, NEFA, total protein, and glucose concentrations. Our results showed that PAG concentrations are not only influenced by the number of fetuses, but also by the ewe’s diet. In particular, the PAG marginal means were higher in the feed-restricted group than in the control group (7.8 ± 0.6 and 10.8 ± 0.9 ng/mL for the control and feed-restricted groups, respectively; p = 0.040). This finding confirms that a dietary restriction between d 24 and d 100 of gestation leads to a growth in placental functions as inferred from the increase in the concentration of the PAG levels. Therefore, the measurement of PAG concentrations, in addition to serving as a marker of pregnancy, can also serve as a marker of placental functionality. Full article

Background: In recent years, undernutrition has remained a significant public health issue in Tunisia, increasing the risk of illness and mortality in young children. Therefore, this study aims to analyse the prevalence and factors contributing to undernutrition among Tunisian children aged 0–23 months. Methods: The study included 3265 children aged 0–23 months from the 2011–2023 Tunisia Multiple Indicator Cluster Surveys (MICS). Trends and logistic regression analyses were used to determine the prevalence and predictors of undernutrition. Results: The prevalence of stunting, wasting, and underweight in infants and children aged 0–23 months has increased by 3.3%, 0.5%, and 2.1%, respectively. Stunting and underweight were more common among infants aged 0–5 months (11.8% for stunting, 8.9% for underweight, p < 0.01), and first-time mothers (8.3% for stunting, 4.1% for underweight, p < 0.01). In 2023, compared to 2011, the odds of stunting, wasting, and being underweight had increased by 22%, 16%, and 70%, respectively. Infants aged 0–5 months had higher odds of undernutrition in all three indices. Children of obese or overweight mothers, and those who started breastfeeding late, were more likely to be stunted. Boys had significantly higher odds of wasting and underweight. Children with low birth weight, and duration of breastfeeding > 12 months, had significantly higher odds of being underweight. Conclusions: This study shows that infants aged 0–5 months, first-time mothers, boys, and children from poor households in Tunisia are at a higher risk of undernutrition. To address the growing issue of undernutrition in Tunisian children, enhancing maternal and child health and nutrition services, improving parental education, and implementing community-based programs that provide breastfeeding and nutritional education to infants born to new mothers and mothers with high/low BMI is recommended.

This systematic review aims to synthesize scientific evidence on the effects of oral nutritional supplementation (ONS) on health-related outcomes and nutritional biomarkers among children and adolescents with undernutrition. The review protocol was reported following the Preferred Reporting Items for Systematic Review and Meta-Analysis Protocols (PRISMA-P) guidelines. A comprehensive keyword and reference search was conducted in seven electronic bibliographic databases: PubMed, Academic Search Complete, Academic Search Premier, CINAHL, Global Health, Web of Science, and Scopus. We identified 14 peer-reviewed articles reporting results from 13 unique studies (eight randomized controlled trials, four pre-post studies, and one observational study). Study participants were recruited from 14 countries/regions, with ages ranging from 1 to 14 years. Outcomes of interest include health-related outcomes (acute diseases and infections) and nutritional biomarkers (e.g., serum iron and zinc). Six of the eight studies examining acute diseases/infections and five of the seven examining nutritional biomarkers reported statistically significant improvement in some, but not all, outcomes. A meta-analysis of three studies found that ONS interventions reduce the incidence of upper respiratory tract infection (URTI) by 39% (95% CI, 0.42–0.91) in children at nutritional risk when compared to dietary counseling (DC) alone. This systematic review suggests that ONS interventions can improve certain health-related outcomes and nutritional biomarkers in undernourished children and adolescents. Specifically, the use of ONS significantly reduces the risk of URTI, highlighting its potential to enhance immune function and break the cycle of undernutrition and infection. Full article

As reported by the FAO, in 2022, approximately 735 million people experienced undernourishment, underscoring the critical need for effective strategies to address micronutrient deficiencies. Among these strategies, the mass fortification of staple foods, particularly rice—a dietary staple for half of the global population—has emerged as one of the most effective approaches. Conventional milling processes diminish the nutritional content of rice, necessitating the development of fortification methods to enhance its nutrient profile. This study investigates advanced fortification techniques to improve the nutritional value of rice, focusing on vitamins B1, B2, and B6, with guidelines from the US Institute of Medicine’s Dietary Reference Intakes. The results indicate that implementing ultrasonic treatments and optimal soaking conditions (60 °C for 60 min) significantly enhances the absorption of these vitamins. Effective parameters included a concentration of 1500 ppm for vitamin B1 and higher levels for vitamins B2 and B6, with a rice-to-vitamin solution ratio of 1:4. These conditions yielded an absorbed vitamin B1 content of 1050 mg/kg, bringing the fortified rice closer to meeting recommended intake levels. Given the global average daily consumption of 100 g of rice per person, this research demonstrates the feasibility of fortifying rice to address nutrient deficiencies effectively and contribute to improved dietary health worldwide. Further enhancement of vitamin B2 and B6 levels remains essential for optimal fortification, highlighting the potential of fortified rice as a sustainable solution for improving global nutrition.

Food fortification with micronutrients was initially justified in developed countries by a lack of availability of micronutrients in staple crops, mainly due to soil exhaustion. However, in Sub-Saharan arable lands, soil fatigue is not predominant, and communities consume mostly home-grown, organic, non-processed crops. Sub-Saharan food systems are nevertheless deeply entwined with food insecurity, driver of illnesses. Family production can promote subsistence, food stability, and self-sufficiency, the main SSA setback being the vicious cycle of poverty and the lack of dietary variety, contributing to malnutrition. Poverty reduction and women’s education are significant strategies for reducing child and adolescent undernourishment. Fortification of foods consumed daily by individuals makes sense and can minimize, if not entirely, eliminate deficiencies. Compulsory mass fortification of foods in Sub-Saharan Africa (SSA) with single micronutrients is, however, controversial since they work in synergy among each other and with the food matrix, for optimal absorption and metabolism. Since the causes of malnutrition are many, caused by diverse, unequal, and unjust food distribution, interrelated with political, social, cultural, or economic factors, education status of the population, season and climatic changes, and effectiveness of nutrition programs, just food fortification cannot solve the composite of all these elements. Further, compulsory fortification is excessive, unproductive, and likely harmful to human health, while many challenges remain in assessing the quality of available premixes. Furthermore, aiming at dietary diversification is the best approach of increasing trace element intake from commonly accessible and easily available food sources. Full article

Introduction: The shift to processed foods in American diets has increased vitamin and mineral deficiencies among adolescents, impacting growth and health, often manifesting as oral lesions. This review study aimed to explore the link between nutritional deficiencies and adolescent oral health to improve guidance and prevent long-term issues. Methods: A systematic review of literature from 2013 to 2023 was conducted on adolescents aged 10–19 years, using PRISMA guidelines. Searches in PubMed, Web of Science, Dentistry & Oral Sciences Source—Ebscohost, and Scopus included peer-reviewed articles, excluding reviews and non-empirical studies. Data were screened and extracted with independent reviews for accuracy. Results: Malnutrition strongly correlates with poor oral health. Undernourished children have a 60% increase in dental caries, exacerbated by high sugar intake. Early malnutrition delays dental eruption, temporarily protecting against caries, while stunting and infections cause enamel defects. Chronic conditions like cerebral palsy and celiac disease worsen oral health, with risks persisting into adulthood. Conclusions: Nutritional deficiencies and oral health are interconnected, requiring integrated healthcare. Early interventions and holistic strategies can improve outcomes and reduce long-term burdens. Comprehensive health education and routine dental evaluations are essential for prevention and treatment, enhancing health across all demographics. Full article
