A Systematic Review and Meta-Analysis

Intrauterine growth restriction (IUGR) may predispose metabolic diseases in later life. Changes in fat-free mass (FFM) and fat mass (FM) may explain this metabolic risk. This review studied the effect of IUGR on body composition in early infancy. Five databases and included studies from all countries published from 2000 until August 2021 were searched. Participants were IUGR or small-for-gestational age (SGA) infants, and the primary outcomes were FFM and FM. Eighteen studies met the inclusion criteria, of which seven were included in the meta-analysis of primary outcomes. Overall, intrauterine growth-restricted and SGA infants were lighter and shorter than normal intrauterine growth and appropriate-for-gestational age infants, respectively, from birth to the latest follow up. They had lower FFM [mean difference -429.19 (p = 0.02)] and FM [mean difference -282.9 (p < 0.001)]. The issue of whether lower FFM and FM as reasons for future metabolic risk in IUGR infants is intriguing which could be explored in further research with longer follow-up. This review, the first of its kind can be useful for developing nutrition targeted interventions for IUGR infants in future.publishersversionpublishe

Daily Folic Acid and/or Vitamin B12 Supplementation Between 6 and 30 Months of Age and Cardiometabolic Risk Markers After 6–7 Years: A Follow-Up of a Randomized Controlled Trial

Background Deficiencies of vitamin B12 and folate are associated with elevated concentrations of metabolic markers related to CVDs. Objectives We investigated the effect of supplementation of vitamin B12 with or without folic acid for 6 mo in early childhood on cardiometabolic risk markers after 6–7 y. Methods This is a follow-up study of a 2 × 2 factorial, double-blind, randomized controlled trial of vitamin B12 and/or folic acid supplementation in 6–30-mo-old children. The supplement contained 1.8 μg of vitamin B12, 150 μg of folic acid, or both, constituting >1 AI or recommended daily allowances for a period of 6 mo. Enrolled children were contacted again after 6 y (September 2016–November 2017), and plasma concentrations of tHcy, leptin, high molecular weight adiponectin, and total adiponectin were measured (N = 791). Results At baseline, 32% of children had a deficiency of either vitamin B12 (<200 pmol/L) or folate (<7.5 nmol/L). Combined supplementation of vitamin B12 and folic acid resulted in 1.19 μmol/L (95% CI: 0.09; 2.30 μmol/L) lower tHcy concentration 6 y later compared to placebo. We also found that vitamin B12 supplementation was associated with a lower leptin–adiponectin ratio in subgroups based on their nutritional status. Conclusions Supplementation with vitamin B12 and folic acid in early childhood was associated with a decrease in plasma tHcy concentrations after 6 y. The results of our study provide some evidence of persistent beneficial metabolic effects of vitamin B12 and folic acid supplementation in impoverished populations.publishedVersio

Enteral Iron Supplementation in Preterm or Low Birth Weight Infants: A Systematic Review and Meta-analysis

BACKGROUND AND OBJECTIVES Iron is needed for growth and development of infants globally, but preterm and low birth weight (LBW) infants are at risk for severe iron deficiencies. To assess the effect of enteral iron supplementation on mortality, morbidity, growth, and neurodevelopment outcomes in preterm or LBW infants fed human milk. Secondary objectives were to assess the effect on biomarkers and dose and timing. METHODS Data sources include PubMed, Embase and Cochrane Library databases to March 16, 2021. Study Selection includes controlled or quasi experimental study designs. Two reviewers independently extracted data. RESULTS Eight trials (eleven reports; 1093 participants, 7 countries) were included. No trials reported mortality. At latest follow-up, there was little effect on infection (very low certainty evidence, 4 studies, 401 participants, relative risk [RR] 0.98, 95% confidence interval [95% CI] 0.56 to 1.73, I2 = 0.00%) and necrotising enterocolitis (3 studies, 375 participants, RR 1.47, 95% CI 0.68 to 3.20, I2 = 0.00%). There was an increase in linear growth (length) (moderate certainty evidence, 3 studies, 384 participants, mean difference 0.69 cm, 95% CI 0.01 to 1.37, I2 = 0%) but little effect on weight, head circumference, or cognitive development. There was an improvement in anemia (moderate certainty evidence, 2 studies, 381 participants, RR 0.25, 95% CI 0.10 to 0.62, I2 = 0.00%) but no effect on serum ferritin. Limitations include heterogeneity in the included studies. CONCLUSIONS There are important benefits for human milk-fed preterm and LBW infants from enteral iron supplementation. However, more randomized control trials are required to improve the certainty of evidence.publishedVersio

Strategic implications of changing rule of halves in hypertension: A cross-sectional observational study

Context: The burden of non-communicable diseases will sooner overwhelm the health system of the country and could curtail future economic development. Hypertension causes highest cardiovascular morbidities. To attain target Blood Pressure (BP), different strategies are required, which are area specific. The validity of rule of halves of hypertension in various settings needs to be studied for developing strategies for that particular geographical area. To utilize the resources in more efficient way, strategies need to differ in rural-urban and underserved- well-served areas. Aims: The present study aims at exploring whether the rule of halves holds good in the city of Mumbai as the findings of such research may have implications on strategies to control hypertension in communities. Hence, the objectives of this study are to ascertain the proportion of persons with hypertension with respect to the status of diagnosis, treatment, adequate treatment, and validate it with existing rule of halves. Setting and Design: Study was conducted in the urban field practice area of a teaching hospital and medical college of Mumbai that comprises 42 chawl (housing structures); study design- cross-sectional observational study. Materials and Methods: This observational cross-sectional study was conducted over a period of 18 months in the field practice area of a teaching hospital and medical college of Mumbai with a total population of 43,069. Sample size was 667. After ethical clearance, participants were interviewed using pretested semi-structured interview schedule that included socio-demographic factors, risk factor evaluation, clinical examination, and anthropometry. Subjects with diagnosed hypertension were questioned thoroughly about hypertension adherence. Statistical Analysis: Descriptive statistics was applied on quantitative data. Results: A total of 667 people from five chawls of age more than 35 years were included into the study. The mean age of study subjects was 50.84 ± 11.47 years. Out of total 667 respondents, 20.3% respondents were normotensive, 50.3% respondents were pre-hypertensive, 25.3% respondents were in stage 1 hypertension, and 4% respondents were in stage 2 hypertension. In contrary to the classical rule of halves, the present study shows only 31% of the diagnosed hypertensives are adequately treated. Conclusions: The strategies in the national programs are from the traditional understanding of rule of halves and emphasize increasing awareness and treatment. Family physician should actively involve in regular screening, treatment, and adherence of hypertension treatment. As a part of primary care, community participation is required for effectively achieving the target BP goal of the population

Use of modern technologies for promoting health at the population level in India

Summary: India, with a population of 1.4 billion, faces health equity challenges due to inaccessible public health systems, particularly in rural areas. Modern technologies like the internet and mobile phones are being used to bridge this gap, enhancing health equity by disseminating vital health information. Health Technology Assessment (HTA) evaluates these technologies, influencing healthcare policy and improving health outcomes. Key strategies include digital health hubs, mobile health units, public-private partnerships, and digital tools for community health workers. To scale these interventions, capacity building, infrastructure development, community engagement, and monitoring are required. Policymakers are urged to prioritize investments in health technologies based on evidence, considering cost-effectiveness, health outcomes, and health equity. Addressing data privacy and security is crucial. Future research should focus on technology-based interventions for maternal and child health
