Dos Santos MERA, da Silva KG, da Silva Souza AP, da Silva ABJ, da Silva RF, da Silva EHA, de Souza SL, Barros WMA. Relationship between vitamin B12 levels and motor development: A systematic review. Clin Nutr ESPEN 2024; 63:148-156. [PMID: 38944829 DOI: 10.1016/j.clnesp.2024.06.026] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/24/2024] [Revised: 04/29/2024] [Accepted: 06/18/2024] [Indexed: 07/02/2024]
Abstract
BACKGROUND AND OBJECTIVES Nutrition plays a crucial role in the development and health of the human brain, from early stages to adulthood. The complex process of neurodevelopment necessitates interaction among various factors, with balance in the concentration of vital macronutrients and micronutrients being essential. Regarding micronutrients, vitamin B12 stands out, playing a vital role in the development and functioning of the motor nervous system. The objective was to investigate the influence of reduced levels of vitamin B12 on infant motor development and analyze the effects of supplementation on this aspect of development. METHODS For this purpose, the criteria of the PRISMA method and registration in the PROSPERO database were used. The search was conducted in the following databases: PubMed (Medline), Scopus, PsycINFO, Web of Science, and ScienceDirect. A total of 684 records were initially identified. RESULTS Of the eight included articles, there was diversity regarding geographical contexts and study designs. The final sample comprised a total of 1,559 participants of both sexes. Studies aimed at correcting low levels of vitamin B12 opted for supplementation, following various protocols that varied in dose, administration method, and duration. At the end of the studies, the serum level of this vitamin ranged from 131 pmol/L to 1141 pmol/L. CONCLUSION There is a complex array of factors contributing to reduced levels of vitamin B12, especially in the early stages of life, which significantly impacts infant motor development. Despite methodological variations among studies, evidence suggests that low levels of vitamin B12 may affect motor development and that supplementation could be an effective means of enhancing motor aspects in healthy children. However, due to the diversity of outcomes, it is important to promote comprehensive public policies to encourage appropriate interventions in this area.

Abstract
In this study, we conducted a systematic literature review of the various micronutrient deficiencies (MNDs) that affect children in India and an examination of whether there is a geographic basis for MNDs. MNDs are a common problem in the developing world, in particular, among children in South Asia. According to the United Nations Children’s Fund, millions of children suffer from stunted growth, cognitive delays, weakened immunity, and diseases because of MNDs. These physical ailments have several economic, social, and public health implications, and they can severely hamper a country’s growth. This study aims to clarify existing data on this topic and highlight the disparities between children living in urban and rural areas in India. The Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines were followed to conduct this systematic literature review of a total of five studies. Study quality was assessed using appropriate checklists, and the studies strengthened the hypothesis that MNDs are common among children in India. Because the selected studies were heterogeneous, no statistical conclusions are drawn here. However, a central premise is that MNDs in children are prevalent in India and are related to poverty. No link between geographic location and MNDs is established; rather, recommendations are made for further research on the topic.

Anemia and Vitamin B-12 and Folate Status in Women of Reproductive Age in Southern India: Estimating Population-Based Risk of Neural Tube Defects. Curr Dev Nutr 2021; 5:nzab069. [PMID: 34027296 PMCID: PMC8128722 DOI: 10.1093/cdn/nzab069] [Citation(s) in RCA: 7] [Impact Index Per Article: 2.3] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/27/2021] [Revised: 04/12/2021] [Accepted: 04/20/2021] [Indexed: 01/04/2023] Open
Abstract
BACKGROUND Women of reproductive age (WRA) are a high-risk population for anemia and micronutrient deficiencies. However, there are few representative population-level data from India, which could help inform evidence-based recommendations and policy. OBJECTIVE To conduct a population-based biomarker survey of anemia and vitamin B-12 and folate status in WRA as part of a periconceptional surveillance program in southern India. METHODS Participants were WRA (15-40 y) who were not pregnant or lactating. Whole blood (n = 979) was analyzed for hemoglobin via a Coulter counter (Coulter HMX). Plasma, serum, and RBCs were processed and stored at -80°C or less until batch analysis. Vitamin B-12 concentrations were measured via chemiluminescence; RBC and serum folate concentrations were evaluated via microbiological assay. Anemia and severe anemia were defined as hemoglobin <12.0 g/dL and <8.0 g/dL, respectively. Vitamin B-12 deficiency and insufficiency were defined as total vitamin B-12 <148 pmol/L and <221 pmol/L, respectively. Folate deficiency and insufficiency were defined as RBC folate <305 nmol/L and <748 nmol/L. A previously developed Bayesian model was used to predict neural tube defect (NTD) prevalence per 10,000 births. RESULTS A total of 41.5% of WRA had anemia and 3.0% had severe anemia. A total of 48.3% of WRA had vitamin B-12 deficiency and 74.3% had vitamin B-12 insufficiency. The prevalence of RBC folate deficiency was 7.6%, and 79.3% of WRA had RBC folate <748 nmol/L, the threshold for optimal NTD prevention. Predicted NTD prevalence per 10,000 births based on RBC folate concentrations was 20.6 (95% uncertainty interval: 16.5-25.5). CONCLUSIONS The substantial burden of anemia, vitamin B-12 deficiency, and RBC folate insufficiency in WRA in this setting suggests an opportunity for anemia and birth defects prevention. Findings will directly inform the development of a randomized trial for anemia and birth defects prevention in southern India.This study was registered at clinicaltrials.gov as NCT04048330.

Abstract
Background Vitamins B12 and folate participate in the one-carbon metabolism cycle and hence regulate fetal growth. Though vitamin B12 deficiency is widely prevalent, the current public health policy in India is to supplement only iron and folic acid for the prevention of anaemia. Prompted by our research findings of the importance of maternal vitamin B12 status for a healthy pregnancy, birth and offspring health outcomes, we evaluated available literature evidence using a systematic review approach, to inform policy. Methods A systematic search was performed for relevant Indian studies in the MEDLINE/PubMed and IndMed databases. We selected studies reporting maternal vitamin B12 status (dietary intake or blood concentrations), and/or metabolic markers of vitamin B12 deficiency (homocysteine, methylmalonic acid) or haematological indices during pregnancy and their associations with outcomes of pregnancy, infancy or in later life. Intervention trials of vitamin B12 during pregnancy were also included. Quality of evidence was assessed on the Grading of Recommendations Assessment, Development, and Evaluation (GRADE) system. We followed the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) statement. Results Of the 635 articles identified, 46 studies met the inclusion criteria (cohort studies-26, case-control studies-13, RCT's -7). There is a high prevalence of vitamin B12 deficiency in Indian women during pregnancy (40-70%) (3 studies). Observational studies support associations (adjusted for potential sociodemographic confounders, maternal body size, postnatal factors) of lower maternal B12, higher homocysteine or an imbalance between vitamin B12-folate status with a higher risk of NTDs (6 studies), pregnancy complications (recurrent pregnancy losses, gestational diabetes, pre-eclampsia) (9 studies), lower birth weight (10 studies) and adverse longer-term health outcomes in the offspring (cognitive functions, adiposity, insulin resistance) (11 studies). Vitamin B12 supplementation (7 RCT's) in pregnancy showed a beneficial effect on offspring neurocognitive development and an effect on birth weight was inconclusive. There is a high quality evidence to support the role of low maternal vitamin B12 in higher risk for NTD and low birth weight and moderate-quality evidence for higher risk of gestational diabetes and later life adverse health outcomes (cognitive functions, risk for diabetes) in offspring. Conclusion In the Indian population low maternal vitaminB12 status, is associated with adverse maternal and child health outcomes. The level of evidence supports adding vitamin B12 to existing nutritional programs in India for extended benefits on outcomes in pregnancy and offspring health besides control of anaemia.

Prevalence of Vitamin B12 Deficiency and Its Associated Risk Factors among Pregnant Women of Rural South India: A Community-based Cross-sectional Study. Indian J Community Med 2021; 45:399-404. [PMID: 33623189 PMCID: PMC7877432 DOI: 10.4103/ijcm.ijcm_403_19] [Citation(s) in RCA: 9] [Impact Index Per Article: 3.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/26/2019] [Accepted: 04/21/2020] [Indexed: 12/12/2022] Open
Abstract
Introduction: Vitamin B12 is essential for the normal functioning of the nervous system and for the formation of red blood cells. Vegetarian diet, low socioeconomic status, and social and religious reasons are known risk factors of its deficiency. Pregnant women, children, and the elderly are vulnerable groups. Indians have the highest prevalence, but the data among pregnant women in the rural setting is lacking. Objectives: The objective of this study is to assess the prevalence of Vitamin B12 deficiency and its associated factors among pregnant women of rural South India. Materials and Methods: A cross-sectional study was conducted to recruit consecutive 120 multigravida women with ≤20 weeks of gestation, attending the mobile doctor run clinic of Kaniyambadi block, Vellore. A structured questionnaire was administered, and blood samples were collected. Results: The prevalence of Vitamin B12 deficiency (<200 pgm/ml) and anemia (Hb ≤10.5 g/dL) was 55% and 17.5%, respectively. Only 11.7% were B12 deficient and anemic. Past history of abortion (odds ratio [OR] = 0.5), fatigue (OR = 0.4), and low B12 intake (OR = 2) was associated only in the bivariate analysis. First trimester (OR = 3.9) and obesity (OR = 9.6) were found to be independent risk factors of Vitamin B12 deficiency. Conclusion: Our study showed a high prevalence of Vitamin B12 deficiency in pregnancy in rural India. Some risk factors were identified. However, studies with a higher sample size will be beneficial to study the associated risk factors better.

Abstract
Background: Vitamin B12 deficiency owing to a vegetarian diet is common in India and is associated with neurodevelopmental disorders.Objective: To investigate the prevalence of vitamin B12 deficiency in infants aged 1-12 months and to correlate the results with neurodevelopment.Methods: A cross-sectional study of 200 infants aged 1-12 months presenting to the emergency department or ward and requiring blood sampling or intravenous cannulation was undertaken in a tertiary-care centre of Northern India. Patients' serum vitamin B12 levels were correlated with Denver development screening test II (DDST II).Results: Of 200 infants recruited, 43 (22%) were vitamin B12-deficient (<211 pg/ml). After excluding 16 (8%) infants who were unsuitable for DDST screening, 21/39 (54%) and 22/145 (15%) were DDST-suspect in the vitamin B12-deficient and sufficient groups, respectively (p = 0.0001). There was a statistically significant correlation between B12 deficiency and an abnormal DDST (p < 0.0001).Conclusion: In India, vitamin B12 deficiency is prevalent in infancy and is associated with neurodevelopmental delay.

Abstract
The EAT-Lancet commission recently suggested that transformation to healthy diets by 2050 will require a reduction of at least 50% in consumption of foods such as red meat and sugar, and a doubling in the global consumption of fruits, vegetables, nuts, and legumes. A diet rich in plant-based foods and with fewer animal source foods confers both improved health and environmental benefits. Notably, the risk of vitamin B12 deficiency increases when consuming a diet low in animal products. Humans are dependent on animal foods such as dairy products, meat, fish and eggs. Vitamin B12 deficiency is common worldwide, especially in populations with low consumption of animal foods because of low socioeconomic status, ethical reasons, or because of their lifestyle (i.e., vegans). According to the European Food Safety Authoroty, the recommended adequate intake of vitamin B12 is 4.0 μg/d for adults, and vitamin B12 requirements are higher during pregnancy and lactation. Infants and children from deficient mothers and elderly people are at risk for vitamin B12 deficiency. Diagnosis of vitamin B12 deficiency is hampered by low specificity of available biomarkers, and there is no consensus yet regarding the optimal definition of low vitamin B12 status. In general, a combination of at least two biomarkers is recommended. Therefore, this review presents an overview of vitamin B12 biochemistry and its biomarkers. We further summarize current recommendations of vitamin B12 intake, and evidence on the associations of vitamin B12 intake from different nutrient-dense animal foods with vitamin B12 status markers. Finally, potential consequences of low vitamin B12 status on different health outcomes for pregnant women, infants and elderly are presented.

Abstract
OBJECTIVE To assess the prevalence of vitamin B12 and folate deficiencies among children residing at high altitude regions of Himachal Pradesh, India. METHODS A total of 215 school children in the age group of 6-18 y were included. Biochemical estimation of serum vitamin B12 and folate levels was undertaken using chemiluminescence immunoassay method. The consumption pattern of foods high in dietary vitamin B12 and folate was recorded using Food Frequency Questionnaire. RESULTS The median levels (interquartile range) of serum vitamin B12 and folate were 326 (259-395) pg/ml and 7.7 (6-10) ng/ml respectively. The prevalence of vitamin B12 and folate deficiency amongst school age children was found as 7.4% and 1.5% respectively. CONCLUSIONS A low prevalence of vitamin B12 and folate deficiencies was found amongst children aged 6-18 y living at high altitude regions in India. This is possibly due to high frequency of consumption of foods rich in vitamin B12 and folate.

Abstract
BACKGROUND Vitamin B12 deficiency in early life can adversely affect the growth of developing brain with myriad of neurodevelopmental manifestations. At this age, the deficiency is usually the result of low maternal levels. OBJECTIVES To assess the vitamin B12 status of healthy exclusively breast-fed Indian infants aged 1 to 6 months and their mothers. METHODS One hundred term exclusively breast-fed infants aged 1 to 6 months attending pediatric outpatient department were recruited. Hemogram, serum B12, folate, and ferritin levels were obtained from each infant-mother pair. RESULTS The prevalence of B12 deficiency in infants was found to be 57%. Forty-six percent of mothers were deficient. There was a positive correlation ( r = .23) between the B12 levels of the infants and their mothers. CONCLUSION There is a high prevalence of vitamin B12 deficiency in Indian infants and their mothers. There is an urgent need to supplement our population with vitamin B12, and the best time to do this would be antenatal.
