“…In this study, all non-verbal items of Stanford Binet fifth edition were non-significant between the control and ID groups, except Quantitative Reasoning and Working Memory items. The findings agreed with the results of Handa et al revealed that iron deficiency impairs the activities that involve verbal working memory [21] .…”

Objective: Determine the effect of iron deficiency anemia (IDA) & iron deficiency (ID), on the cognitive functions in children and its consequences. Patients and Methods: Three groups of children were enrolled in this case-control study with an age range of 3-8 years. They were selected from pediatric and phoniatric clinics in Egypt. Control group (CG): thirty normal children. Case groups were divided into GroupI: Nineteen Delayed language development children had ID only, Group II: Thirty Delayed language development children had iron deficiency anemia (IDA). Groups were subjected to (1) Full history taking (focusing on nutritional history). ( 2) CBC by automatic cell counters. (3) Iron status through estimation of serum ferritin level by ELISA. (4) Assessment of cognitive functions by assessment of Non-verbal Intelligent Quotient (NV-IQ) using Stanford Binet 5 th Edition measuring (fluid reasoning, knowledge, quantitative reasoning, visual-spatial processing, and working memory). ( 5) Assessment of language-by-language test to confirm diagnosis of delayed language development. Results: Under the umbrella of faulty eating habits, there was a direct correlation between the NV-IQ and the deterioration of iron status with their consequence on delaying language development. Conclusion: There is a necessary to assess NV-IQ and iron status in any child with delayed language development with poor attention span, intelligence, sensory perception functions, emotions, and behavior, especially with the condition of faulty eating habits.

“…Since ≥ 2 MD were more common in anaemic children than non-anaemic (79.9% vs 67.0%, p<0.001), therefore anemia can be taken as surrogate marker. Studies have also reported that children with decreased hemoglobin levels were poor performers in cognitive tests [ 15 ]. Previous literature shows that iron, folate and vitamin B12 deficiencies are found to be associated with low scorings in cognitive tests [ 39 – 42 ], which is similar to the findings of current study.…”

“…Studies conducted in India, among school aged children and adolescents, reported widespread deficiency of micronutrients [7,[15][16][17][18][19]. However, no comprehensive multicentric study has been conducted in India to assess the impact of various crucial micronutrient deficiencies on general intelligence as well as specific cognitive functions in children and adolescents.…”

Background Micronutrient deficiency (MD) is associated with deficits in cognitive functioning of children. However, no comprehensive multicentric study has been conducted in India to explore the role of multiple MD in cognition of children and adolescents. The present study aimed to explore association of MD with level of general intelligence and specific cognitive functions, in urban school-going children and adolescents across ten cities of India. Method Cross-sectional multicentric study, enrolled participants aged 6–16 years. Blood samples were collected for biochemical analysis of calcium, iron, zinc, selenium, folate, vitamin A, D and B12. Colored Progressive Matrices / Standard Progressive Matrices (CPM/SPM), Coding, Digit Span and Arithmetic tests were used for the assessment of cognitive functions of participants. Height and weight measures were collected along with socio-economic status. Results From April-2019 to February-2020, 2428 participants were recruited from 60 schools. No MD was found in 7.0% (134/1918), any one MD in 23.8% (457/1918) and ≥ 2 MD in 69.2% (1327/1918) participants. In presence of ≥ 2 MD, adjusted odds ratio (OR) for borderline or dull normal in CPM/SPM was 1.63, (95% CI: 1.05–2.52), coding was 1.66 (95% CI: 1.02–2.71), digit span was 1.55 (95% CI: 1.06–2.25) and arithmetic was 1.72 (95% CI: 1.17–2.53), controlling for gender, socioeconomic status and anthropometric indicators. Conclusion Since ≥ 2 MD were found in more than 2/3rd of participants and was associated with impairment in cognitive function, attempts must be made to ameliorate them on priority in school going children in India. Trial registration number CTRI/2019/02/017783.

Background Limited research addressed links between nutritional status, dietary habits, and cognitive functions in young children. This study assessed the status of cognitive functions and their association with nutritional status and dietary habits of school age children of Bangladesh. Methods This cross-sectional multi-centre study was conducted on 776 participants in 11 conveniently selected educational institutions. A printed questionnaire with three sections (Section 1: background information, section 2: PedsQL™ Cognitive Functioning Scale, and section 3: semi-quantitative food-frequency questionnaire) was utilized for the data collection purpose. Sections 1 and 3 were self-reported by parents, and trained volunteers completed section 2 in-person along with the anthropometric measurements. Statistical analyses were done in Stata (v.16). Mean with standard deviation and frequencies with percentages were used to summarize quantitative and qualitative variables, respectively. Pearson’s chi-square test and Spearman’s rank correlation coefficient were used to explore bivariate relationships. Results The mean age of the participants was 12.02±1.88 years, and the majority (67%) were females. The prevalence of poor cognitive function was 46.52%, and among them, 66.02% were females. In terms of body mass index (BMI), 22.44% possessed normal weight, 17.51% were overweight, and 5.19% were obese. This study found a statistically significant relationship between BMI and cognitive functions. Furthermore, different dietary components (e.g., protein, carbohydrate, fat, fiber, iron, magnesium) showed a significant (p<0.05 for all) weak positive correlation with cognitive function. Conclusion BMI and dietary habits were associated with the cognitive function of young children in Bangladesh. Although the cross-sectional design of the study precludes causal relationships from being determined, the study finding deserves further examination via longitudinal research.
