Background/Objectives: Malnutrition is a common problem in children with cerebral palsy (CP). The aim of this study was to investigate the suitability and diagnostic performance of mid-upper arm circumference (MUAC) z-score in diagnosing wasting in children with CP, and its impact on diagnostic accuracy when evaluated concomitantly with additional clinical factors (birth weight, history of phototherapy). Methods: This single-center, cross-sectional study included 83 children with CP, aged 6 months–17 years, followed-up in our clinic. Anthropometric measurements (MUAC, Body Mass Index (BMI)) and clinical data (birth weight, history of phototherapy, Gross Motor Function Classification System (GMFCS)) were prospectively collected. Wasting was defined according to the BMI z-score ≤ −2 criteria. The diagnostic performance of MUAC z-score was evaluated by Receiver Operating Characteristic (ROC) analysis. The contribution of additional covariates was examined using logistic regression analysis and the backward elimination method. Results: MUAC z-score alone demonstrated good discrimination in diagnosing wasting with an Area Under the Curve (AUC) value between 0.805 and 0.821, but its sensitivity was limited (67.0%). No statistically significant difference was found in diagnostic performance between MUAC measurements of the right arm, left arm, and the unaffected arm (p > 0.050). In logistic regression analysis, MUAC z-score (p = 0.001), birth weight (p = 0.014), and a history of phototherapy (p = 0.046) were found to be significantly associated with wasting malnutrition. The simplified model including these variables yielded an AUC value of 0.876. Conclusions: MUAC z-score is a usable tool for wasting malnutrition screening in children with CP. Although its sensitivity is limited when used alone, its diagnostic accuracy increases when evaluated concomitantly with additional clinical factors such as birth weight and a history of phototherapy. This combined approach may offer clinicians a more robust tool for the early diagnosis and management of wasting malnutrition in children with CP. Full article

Background/Objectives: Malnutrition is prevalent among hospitalized older adults with multimorbidity, leading to adverse health outcomes and increased healthcare costs. An accurate assessment of resting energy expenditure (REE) is crucial because an inaccurate estimation of energy needs may result in unintentional underfeeding or overfeeding, both of which can worsen nutritional status and clinical outcomes. While indirect calorimetry (IC) is the preferred method, its clinical applicability is limited. Prediction equations are commonly used, but their accuracy in older Asian patients with multimorbidity remains unclear. Methods: This multicenter, cross-sectional study enrolled 400 patients aged ≥65 years from March to December 2023 in Outram Community Hospital (OCH) and Sengkang Community Hospital (SKCH). Participants’ REE was measured using indirect calorimetry. We compared the performance of the newly developed novel prediction equations (PEs), derived from readily accessible or easily measured anthropometric data, against established equations. Statistical analysis included the calculation of R², the root mean square error (RMSE), and the intraclass correlation coefficient (ICC) to assess reliability and goodness of fit. Results: A high prevalence (85%) of multimorbidity was observed among the participants. REE increased progressively with body mass index (BMI) across all groups (865.6–1269.4 kcal in females; 889.1–1269.4 kcal in males). The novel PEs (RMSE: 186–191; ICC: 0.5–0.52) demonstrated improved accuracy and stronger reliability compared to conventional equations (RMSE: 222–258; ICC: 0.271–0.460). Conclusions: Our newly developed PEs offer potentially valuable tools for precise REE estimation in hospitalized older Asian patients with multimorbidity. Further external validation and investigation in diverse populations are necessary to confirm these results. Full article

Background/Objectives: Despite ongoing national interventions, pockets of acute malnutrition persist in rural settings of South Africa, contributing to disproportionate rates of child morbidity and mortality. This study aimed to identify risk factors associated with acute malnutrition among under-five children attending primary healthcare facilities in Msinga, KwaZulu-Natal Province, with a specific focus on dietary diversity and selected infant and young child feeding indicators. Methods: A cross-sectional, facility-based study was conducted among 415 mother–child pairs attending five randomly selected PHC facilities in the Msinga sub-district. Participants were selected using a multistage sampling design from a sampling frame of 18,797 under-five children. Of the 551 mother–child pairs approached; the final analytic sample comprised 415 observations. Data were collected through structured interviews, anthropometric assessments, and dietary diversity scores (DDS). Data were analyzed using Stata 18, and Poisson regression was applied to identify risk factors. Results: The prevalence of acute malnutrition was 29% based on weight-for-height/length z-scores (WHZ/WLZ) and 27% based on mid–upper-arm circumference z-scores (MUACZ). Children aged ≥36 months had significantly higher prevalence of acute malnutrition (aPR = 1.62; 95% CI: 1.15–2.10). Children from households with five or more members had reduced risk (aPR = 0.66; 95% CI: 0.45–0.74), and those born full-term showed a strong protective association (aPR = 0.39; 95% CI: 0.23–0.64). Maternal age was associated with reduced risk, with children of mothers aged 25–34 years (aPR = 0.67; 95% CI: 0.48–0.93) and ≥35 years (aPR = 0.58; 95% CI: 0.35–0.84) experiencing significantly lower prevalence. Mixed feeding was significantly associated with reduced risk (aPR = 0.86; 95% CI: 0.55–1.17), while a DDS ≥4 was protective (aPR = 0.41; 95% CI: 0.04–0.84). Consumption of protein-rich foods was notably low, with only 21% consuming flesh foods and 10% consuming eggs. Conclusions: Acute malnutrition in under-five children was significantly associated with poor diet quality, older age, low household income, and mixed feeding practices. Protective factors included full-term pregnancy, larger households, older maternal age, and adequate dietary diversity, highlighting the importance of targeted, multisectoral interventions.

Background/Objectives: The phase angle (PhA) is an emerging biomarker reflecting the cellular integrity and nutritional status. This study aimed to explore potential associations between the PhA, clinical severity scores, and 60-day survival outcomes following an admission to the Intensive Care Unit (ICU). Methods: This prospective, single-center study included 43 critically ill patients admitted to the ICU at Evangelismos General Hospital between May and November 2024. Patients were stratified by their PhA (≤5.4° vs. >5.4°). The PhA was measured at admission and subsequently on days 5–7, 10–11, 13–14, and until discharge. Severity scores (SOFA and APACHE II) were recorded. Between-group differences were assessed using independent samples t-tests and Mann–Whitney U tests, as appropriate. Survival was analyzed using Kaplan–Meier curves and Cox proportional hazards models. Results: The mean age was 54.6 ± 17 years; 63.6% were male. At ICU admission, patients with a PhA > 5.4° were significantly younger (p < 0.001) and had a higher fat-free mass (p < 0.001), greater calf circumference (p < 0.001), higher extracellular water (p < 0.001), larger mid-upper arm circumference (p = 0.009), and higher resting energy expenditure per kilogram (27.4 vs. 23.1 kcal/kg, p = 0.002). The PhA declined significantly during the ICU stay (p < 0.001). The Kaplan–Meier analysis showed a significantly shorter survival in patients with a PhA ≤ 5.4° (HR: 6.32, p = 0.019), which remained significant after adjusting for sepsis (p = 0.017). In a multivariable Cox regression, both PhA and APACHE II scores independently predicted mortality. Conclusions: While limited by a small sample size and single-center design, these findings support the further exploration of the PhA as a monitoring tool in critical care. Full article

This study examined the relationships between mid-arm circumference (MAC) and calf circumference (CC) with cognitive performance, considering the moderating effect of apolipoprotein E ε4 allele (APOE4) status. Data from 196 older adults (65–90 years) in the General Lifestyle and AD (GLAD) study were analyzed. Cognitive performance was assessed using the CERAD neuropsychological battery, with episodic memory score (EMS) and non-memory score (NMS) as primary outcomes. Multiple linear regression analyses examined associations between MAC, CC, and waist circumference (WC) with cognition, adjusting for key covariates. Interaction effects with APOE4 status were also explored. Higher MAC (or MAC/WC) significantly correlated with better EMS, while higher CC (or CC/WC) correlated with better NMS, even after Bonferroni correction (P_B < 0.0125). These associations were stronger in APOE4-negative individuals but not significant in APOE4-positive participants. WC was not associated with cognitive measures. The results suggest that Upper- and lower-limb musculature may play distinct roles in cognitive function, with MAC linked to episodic memory and CC to non-memory cognition, particularly in APOE4-negative individuals. These findings highlight the potential of muscle health maintenance as a strategy for preserving cognitive function in aging populations. Full article

Objective: Malnutrition remains a global challenge to child development, with urban slums in India experiencing high rates of protein deficiency. This study aimed to evaluate the effectiveness of a low-cost, fish bycatch-derived protein supplement in supporting catch-up growth among malnourished children. Methods: Using the Sustainable Community Partnership and Empowerment (SCOPE) model, we implemented a 90-day intervention with daily 10 g of Advanced Protein Powder (APP), produced from underutilized fish bycatch. Forty-six malnourished children (aged 3–6) from Bengaluru slums were randomized into a Control group receiving caloric support or an APP supplement group. Growth indicators, cognition, and caregiver perspectives were assessed. Results: Children receiving the APP supplement showed a significant increase in the weight-for-age percentile (underweight), rising by 7.59%, compared to 0.59% in the Control group (p = 0.02185). Muscle growth, measured by mid-upper arm circumference, also improved significantly in the APP Group (p < 0.05). In the first month, APP supplementation led to a significant height gain of 1.86 cm (p < 0.001), whereas the Control group showed no change (p > 0.05). Additionally, APP supplementation enhanced cognitive function, visual processing, short-term memory, and planning ability, with sustained effects at six months (p < 0.05). Caregivers reported noticeable improvements in children’s vitality, appetite, focus, and engagement in social and learning activities. Conclusions: Bycatch-derived protein supplementation, implemented through the SCOPE model, enhanced physical growth, behavior, and cognition in malnourished children in urban slums. Future studies should investigate the long-term effects, scalability, and adaptability of this sustainable solution for addressing child malnutrition. Full article

Fetal malnutrition, characterized by inadequate fat and muscle accretion during intrauterine development, has been linked to adverse outcomes, ranging from neonatal complications to long-term developmental and metabolic disorders. Traditionally, growth curves and birth weight have guided the assessment of newborns’ nutritional status; however, these measures often do not accurately reflect changes in body composition. This review compares several evaluation methods—CAN score (Metcoff methodology), body mass index (BMI), Ponderal Index (PI), McLaren Index, mid–upper arm circumference (MUAC), and plicometry—to provide suggestions on selecting the most appropriate approach, depending on the healthcare setting and population needs. Findings from multiple international studies indicate that the CAN score and BMI are among the most accurate tools, offering better sensitivity and specificity than traditional anthropometric indicators. The CAN score, based on a clinical observation of fat deposits, skin texture, and muscle tone, has been widely used in Latin America and remains a practical and cost-effective option. Nonetheless, recent research suggests that BMI, mainly when used alongside the PI, may outperform the CAN score in certain contexts. Considering the complexity of fetal nutritional assessments, integrating multiple methods enhances the diagnostic accuracy. Early identification of malnourished newborns is essential for timely intervention and improved long-term outcomes. Standardizing these diagnostic tools globally could advance efforts to reduce neonatal morbidity and mortality by 2030. Full article

Background/Objectives: Amyotrophic lateral sclerosis (ALS) is a progressive neurodegenerative disorder affecting motor neurons in the brain and spinal cord, leading to muscle weakness, atrophy, and paralysis. Treatment focuses on symptom management, using medication, physiotherapy, and nutritional support. In this context, endoscopic gastrostomy (PEG) can provide adequate feeding, hopefully improving nutrition and preventing complications. Methods: We studied ALS patients undergoing PEG over three months post-procedure, using anthropometry ((BMI)—body mass index; (MUAC)—mid-upper arm circumference; (TSF)—tricipital skinfold; (MAMC)—mid-arm muscle circumference) and laboratory data (Albumin; Transferrin; total cholesterol and hemoglobin), evaluating survival, complications, and nutritional/clinical status. Statistical analysis included Kaplan–Meier survival estimation and Cox regression to assess nutritional markers associated with survival. Results: 150 ALS patients underwent gastrostomy, mostly older adults (mean age: 66.1 years; median: 67). Mean survival was 527 [95% CI: 432–622] days, median 318 [95% CI: 236–400]. ALS bulbar subtype, MUAC and MAMC positively impacted PEG-feeding survival time (p < 0.05, Wald test). During the first three months of PEG feeding, each unit increase (cm) in MUAC and MAMC lowered death risk by 10% and 11%, respectively, highlighting the importance of nutrition care for survival. The bulbar subtype showed higher PEG feeding survival, with a 55.3% lower death hazard than the spinal subtype. There were no major PEG complications. Conclusions: ALS patients present a high risk of malnutrition. Patients that improved MAMC and MUAC in the first three PEG-fed months presented longer survival. Early PEG nutrition, even when some oral feeding is still possible, may reinforce the preventative role of enteral feeding in maintaining nutrition and potentially improving survival. Full article

Background: Liver cirrhosis is associated with significant nutritional challenges, including malnutrition, sarcopenia, and frailty, which impact clinical outcomes. The severity of these issues may vary between inpatient and outpatient settings, but there is a limited understanding of how these conditions manifest in these populations. This study aims to compare the nutritional status, dietary intake, and frailty in outpatients and inpatients with liver cirrhosis and to explore potential sex-specific differences. Methods: This prospective observational study enrolled 195 patients with liver cirrhosis from the Gastroenterology ward and Outpatient Clinic of Policlinico Umberto I, Sapienza University of Rome, between May 2023 and July 2024. Nutritional status was assessed using anthropometric measurements, dietary recall, and food frequency questionnaires. Sarcopenia was evaluated using the SARC-F questionnaire and handgrip strength. Frailty was assessed using the Liver Frailty Index (LFI). Data on clinical characteristics, comorbidities, and disease severity were also recorded. Results: The inpatient group (n = 69) had significantly lower BMI, mid-upper arm circumference, and triceps skinfold compared to outpatients (n = 126). Inpatients exhibited higher frailty, with 73.9% classified as frail according to the LFI, compared to 39.6% in outpatients (p < 0.001). Dietary intake revealed that 91% of inpatients had an energy intake deficit compared to 76% of outpatients (p = 0.009). Protein intake was inadequate in 84% of inpatients versus 61% of outpatients (p < 0.001). Sex-specific analysis showed that females had a higher prevalence of sarcopenia than males (64.4% vs. 38.2%, p < 0.001) and experienced more significant protein deficits (74.3% vs. 57.6%, p = 0.021). Females also had higher LFI score (4.77 ± 0.88 vs. 4.45 ± 0.91, p = 0.034). Multivariate analysis showed that CTP, LFI, and protein deficit are independently associated with hospitalization. Conclusions: Inpatients with liver cirrhosis are at higher risk for malnutrition, frailty, and inadequate nutrient intake compared to outpatients, emphasizing the need for targeted nutritional interventions in hospital settings. Additionally, females with cirrhosis are more prone to sarcopenia and frailty, requiring gender-specific approaches to nutrition. Full article

This quasi-experimental trial examined the relationship between Schistosoma haematobium infection and nutritional status, and the impact of single dose praziquantel (PZQ) therapy on undernutrition. A total of 353 children were examined, 112 of which were infected with S. haematobium and treated with PZQ. Children’s heights, weights, and mid-upper arm circumferences (MUAC) were measured at baseline and one month post-treatment. Infected children had significantly smaller mean BMI-for-age z-scores (BAZ) (−1.16 vs. 0.11, p < 0.01) and weight-for-age z-scores (WAZ) (−0.61 vs. −0.31, p = 0.03) than the uninfected ones at baseline. S. haematobium infection was associated with underweight (adjusted OR: 1.76, 95% CI: 1.63–1.90). One month after treatment, BAZ, WAZ, height for age z-scores (HAZ), and MUAC scores were comparable between treated and control children. However, there was a significant decrease in the prevalence of underweight among treated children, while no significant change was observed in the control group one month post-treatment. In conclusion, children infected with S. haematobium are likely to suffer from undernutrition; however, single dose PZQ therapy may not improve their nutritional status within one month of treatment. Future studies could have longer follow-up periods to better estimate the drug’s effect on nutrition. Full article

Background/Objectives: The 2023 World Health Organization (WHO) guideline on infants aged under six months (u6m) wasting now includes mid-upper arm circumference (MUAC) and weight for age Z score (WAZ) as malnutrition treatment programme enrolment criteria. Evidence for the new criteria and optimal cut-offs is, however, sparse. We aimed to explore the potential caseload implications of the new criteria and explore how different cut-offs might affect them. Methods: We conducted a secondary analysis of data from 1048 Ethiopian infants u6m using STATA software version 17. Frequency tables and percentages were used to present malnutrition across various characteristics. The chi-square test with 95% confidence intervals (CIs) at a p value of <0.05 was used to compare infant caseload identified by the WHO-2023 versus WHO-2013 criteria. Results: We found substantial overlaps among anthropometric indicators of malnutrition in infants defined by the WHO-2023 programme enrolment criteria. New WHO criteria result in a larger potential caseload (19.2% for 6 weeks to 6 months and 15.1% for infants under 6 weeks) compared with WHO-2013 criteria (2.4%). Whilst there are marked overlaps between low WAZ, low WLZ, and low MUAC, they capture different infants. An MUAC of <110 mm alone would capture only a third of all cases identified by WAZ and/or WLZ < −2. Conclusions: In Ethiopia, the WHO-2023 criteria markedly increase malnutrition caseloads compared with WHO-2013 criteria. There might be a case for increasing MUAC thresholds in MUAC-focused programs where WLZ or WAZ measurements are difficult. Future longitudinal data are needed to know which criteria best identify infants at highest risk of mortality/morbidity/poor development. Full article

Background: Swallowing dysfunction is a prevalent but often overlooked problem in long-term care facilities. This study investigated the relationships between nutritional deficits, frailty, oral health, and swallowing dysfunction. Additionally, we explored the associations between oral muscle weakness, frailty markers, and swallowing dysfunction. Methods: We recruited 373 participants from seven long-term care facilities across Taiwan. Swallowing function, frailty, nutrition status, and oral health were assessed by research staff. Oral muscle function was evaluated through tongue strength measurements, cheek bulging function tests, the Repetitive Saliva Swallowing Test (RSST), and a diadochokinetic task. Frailty was assessed through grip strength as well as mid-upper arm and calf circumference measurements. Results: The Functional Oral Intake Scale revealed that 97 participants (26%) had swallowing dysfunction. Participants with swallowing dysfunction had poorer nutritional status, higher frailty levels, and worsened oral health. Frailty was the factor most strongly associated with swallowing dysfunction. Participants with swallowing dysfunction also exhibited lower tongue pressure, decreased cheek-bulging ability, fewer repetitions in the diadochokinetic task, lower scores on the RSST, lower calf circumferences, and lower grip strength. Logistic regression demonstrated that cheek bulging was most strongly associated with swallowing dysfunction. Furthermore, lower grip strength was significantly associated with swallowing dysfunction. Conclusions: Frailty was most strongly associated with swallowing dysfunction, followed by poorer nutritional status and worsened oral health. These factors should be thoroughly assessed in long-term care residents. Participants with swallowing dysfunction also experienced oral muscle weakness, particularly in cheek bulging. Grip strength, which represents frailty, was directly associated with swallowing dysfunction and could serve as a crucial indicator of swallowing dysfunction. Full article

Background/Objectives: This study aimed to evaluate the correlation of mid-upper arm circumference (MUAC) z-scores with body mass index (BMI) and weight-for-height (WFH) z-scores to determine its reliability in identifying malnutrition and its potential in clinical practice in healthy children and adolescents. Methods: Our study included 906 healthy children and adolescents aged between 2 months and 18 years who were admitted to University Hospital’s General Pediatrics Clinic and attended 12 primary schools in 6 additional Izmir provinces. Anthropometric measurements (weight, length/standing height, MUAC, BMI, WFH) were performed. The relationship between MUAC z-scores, BMI, and WFH z-scores of cases with malnutrition were evaluated. Results: According to the WHO BMI z-score classification, 6 (0.7%) of the children were defined as having severe undernutrition, 43 (4.7%) as moderate undernutrition, 146 (16.1%) as mild undernutrition, 486 (53.6%) as normal, 142 (15.7%) as overweight, and 83 (9.2%) as obese. At any age over two years, fair agreement was observed between MUAC z-scores and WHO BMI z-scores in defining malnutrition alone compared to other growth measures (weighted kappa = 0.371). Under two years of age, the correlation between MUAC z-scores and BMI z-scores showed moderate agreement in detecting overweight and obesity (weighted kappa = 0.479), and between MUAC and WHO WFH z-scores showed moderate agreement (kappa = 0.252). Conclusions: The study found a moderate and fair connection between MUAC z-scores and other criteria. However, further MUAC z-score screening and diagnostic power testing in larger pediatric populations are needed to validate its use alongside other key anthropometric indicators in malnutrition diagnosis. MUAC measurement should be popularized in routine pediatric outpatient clinics to detect malnutrition quickly. Full article

Background: Appropriate complimentary feeding (CF) has the potential to improve growth and development in infants from 6 months to 2 years of age. This study’s aim was to assess the effect of a CF education program on the nutritional status of infants aged 3–12 months in the Polokwane Municipality. Methods: A longitudinal (non-randomized), quasi-experimental intervention study was conducted among 187 caregivers. The caregiver-infant pairs (CIPs) in the intervention group (n = 95) received CF education and a six-month telephone follow-up support. The CIPs in the control group (n = 94) received no intervention. We collected data at baseline and end line using structured questionnaires. Intervention effectiveness was evaluated by comparing mean changes in anthropometric measurements between intervention and control groups using difference-in-difference analysis. Per protocol, analysis was run. Results: The results show that the children in the intervention group gained more weight after the intervention, were taller, and the mid-upper arm circumference (MUAC) increased more than in the control group. At baseline, the weight of infants was 7.37 ± 0.83 and 6.69 ± 0.13 kg in the intervention and control. At end line, significant weight and length gain were observed in the intervention group (difference-in-difference (DID) = 1.82 kg, p < 0.001) and (DID = 7.78 cm, p < 0.01), respectively. The intervention group showed significant gain in MUAC of 1.68 cm (p = 0.047), with no noticeable effect on the head circumference at end line; DID (0.16 cm; p = 0.950). Conclusions: Community-based nutrition intervention programs can effectively improve the anthropometric nutritional status of children aged 3–12 months. Full article

Background/Objectives: Despite advances in maternal nutritional knowledge, the effect of maternal diet, micronutrient status and undernutrition, and the effect of maternal supplementation on fetal, neonatal and infant outcomes still have gaps in the literature. This overview of reviews is intended to assess the available information on these issues and identify the main maternal nutritional factors associated with offspring outcomes in low- and middle-income countries as possible targets for public health interventions. Methods: The literature search was performed in Medline (PubMed) and Cochrane Library datasets in June 2024. Pre-specified outcomes in offspring were pooled using standard meta-analytical methods. Results: We found consistent evidence on the impact of maternal undernutrition indicated by low body mass index (BMI), mid-upper arm circumference (MUAC), and stature, but not of individual micronutrient status, on intrauterine-growth retardation, preterm birth, low birth weight, and small for gestational age, with research showing a possible effect of maternal undernutrition in later child nutritional status. Studies on micronutrient supplementation showed possible beneficial effects of iron, vitamin D, and multiple micronutrients on birthweight and/or decreasing small for gestational age, as well as a possible effect of calcium on preterm birth reduction. Interventions showing more consistent beneficial outcomes were balanced protein-energy and lipid base supplements, which demonstrated improved weight in newborns from supplemented mothers and a decreased risk of adverse neonatal outcomes. Conclusions: Further research is needed to identify the benefits and risks of maternal individual micronutrient supplementation on neonatal and further child outcomes. Full article
