Project description:BackgroundCoverage of iron-folic acid (IFA) supplementation is a key indicator for tracking programmatic progress within and across countries. However, the validity of maternal report of this information during household surveys has yet to be determined.ObjectivesThis study aimed to examine the validity of maternal recall of receipt of IFA supplementation during antenatal care (ANC) and factors associated with accuracy of maternal recall.MethodsA longitudinal cohort design was employed. The direct observation of the IFA received during all ANC visits at the 5 study health posts served as the "gold standard" to the maternal report of IFA received during the postpartum interview. Individual-level validity was assessed by calculating indicator sensitivity, specificity, and AUC. The inflation factor (IF) measured population-level bias. A multivariable log-binomial model was used to assess factors associated with accurate recall.ResultsThe majority (95.8%) of women were observed receiving IFA during pregnancy. Women overreported the number of IFA tablets received compared with what was observed during ANC visits (mean difference: 45 tablets). Maternal report of any IFA receipt was moderate (AUC = 0.60; 95% CI: 0.50, 0.71), and population bias was low (IF = 1.01). However, the individual-level validity was poor across the 7 IFA tablet count categories; the AUC for categories ranged from misleading to moderate. Driven by the trend of maternal overreport, the IF indicated that maternal report drastically underestimated the coverage of lower tablet categories and overestimated the coverage of higher tablet counts. Accuracy of maternal report was not associated with months since last ANC observation nor any maternal characteristics.ConclusionsMaternal report of the amount of IFA supplementation received during pregnancy produced extremely biased population coverage and performed poorly to moderately for individual-level validity. It is imperative to improve this indicator because it is used in global frameworks and national program planning.

Project description:ObjectiveThe current study assessed intake of iron-and-folic-acid (IFA) tablet/syrup (grouped into none, < 100 d of IFA consumption or < 100 IFA and ≥ 100 d of IFA consumption or ≥ 100 IFA) among prospective mothers and its association with various stages of low-birth weight (ELBW, extremely low-birth weight; VLBW, very low-birth weight and LBW, low-birth weight) and neonatal mortality (death during day 0-1, 2-6, 7-27 and 0-27) in India.DesignThe cross-sectional, nationally representative, 2015-2016 National Family Health Survey (NFHS-4) data were used. Weighted descriptive analysis and multiple binary logistic regression modelling were used.SettingNFHS-4 covered 640 districts from thirty-seven states and union territories of India.ParticipantsA total of 120 374 and 143 675 index children aged 0-59 months were included to analyse LBW and neonatal mortality, respectively.ResultsOverall, 30·7 % mothers consumed ≥ 100 IFA in 2015-2016, and this estimate ranged from 0·0 % in Zunheboto district of Nagaland state to 89·5 % in Mahe district of Puducherry of India. Multiple regression analysis revealed that children of mothers who consumed ≥ 100 IFA had lower odds of ELBW, VLBW, LBW and neonatal mortality during day 0-1, as compared with mothers who did not buy/receive any IFA. Consumption of IFA (< 100 IFA and ≥ 100 IFA) had a protective association with neonatal death during day 7-27 and 0-27. Consumption of IFA was not associated with neonatal death during day 2-6.ConclusionsWhile ≥ 100 IFA consumption during pregnancy was found to be associated with preventing select types of LBW and neonatal mortality, a large variation in coverage of ≥ 100 IFA consumption across 640 districts is concerning.

Project description:Studies have indicated that altered maternal micronutrients and vitamins influence the development and susceptibility of newborns to chronic diseases. Among these, folic acid (FA) plays a key role in the synthesis and repair of DNA, along with maintenance of epigenetic DNA methylation. Deficiency of FA has been associated with the pathogenesis of neural tube defects. Since FA can modulate DNA methylation and affect gene expression, we investigated the effect of gestational FA supplementation on the expression of genes in the offspring brain. Our results suggest that a maternal ten-fold increase in FA supplementation alters the expression and dysregulates a number of genes in the offspring brain, including many involved in development. While a number of genes that were dysregulated were common to both male and female pups, there were sex differences in gene expression changes. C57BL/6J female mice were separated into two groups of ten mice and supplemented with a custom diet. One week prior to mating the low-dose group of female mice were fed a custom AIN-93G amino acidM-bM-^@M-^Sbased diet (Research Diet, Inc. New-Brunswick, NJ), with FA at 0.4 mg/kg, while the high-dose group received FA at 4 mg/kg diet. Tissues from the cerebral hemisphere of three independent pups of same gender were pooled together. A total of three microarray gene expression studies have been performed (0.4mg/kg or 4mg/kg both male and female) and the mean was used for comparison.

Project description:BackgroundMaternal folic acid supplementation is protective against the development of neural tube defects (NTDs) in babies. However, recent public-facing communications have raised concerns about a causal relationship between folic acid supplementation, particularly after the first trimester, and ankyloglossia (tongue-tie) in infants. Non-evidence-based communications are potentially harmful because they could adversely affect adherence to folic acid supplementation, increasing NTD occurrence. This study aimed to review evidence on the relationships between maternal folic acid supplementation during preconception and/or pregnancy and the risk of ankyloglossia in infants.MethodsWe searched the databases MEDLINE, EMBASE, Cochrane CENTRAL, and Scopus. We searched for observational, and interventional studies, and systematic reviews investigating the effect of maternal folic acid supplementation during preconception or pregnancy on the occurrence of ankyloglossia in offspring. The search was registered on PROSPERO on 01/12/2022, ID: CRD42022375862.ResultsThe database searches yielded 93 articles. After removing duplicates and screening titles and abstracts, 26 remained. One article was judged relevant for inclusion in analyses; a case-control study that directly mentions the relationship between folic acid supplementation and ankyloglossia. This study reported that regular intake of folic acid supplements was higher in women with infants with ankyloglossia. However, this study has limitations regarding design, selection bias, and confounding, calling the findings into question.ConclusionsInsufficient evidence exists for a relationship between folic acid supplementation and ankyloglossia. Currently, the benefits of folic acid supplementation far outweigh the risks. This must be clearly communicated to patients by their clinicians during preconception and antenatal care.

Project description:Iron deficiency anaemia during pregnancy is a common public health problem that negatively affects maternal and newborn health. This study aims to identify the rate of maternal compliance with the recommended iron and folic acid (IFA) supplementation during pregnancy and to identify factors associated with maternal compliance and non-compliance. A hospital-based cross-sectional study was conducted among 703 women at 0-4 days postpartum. The prevalence of anaemia at the initial antenatal clinic (ANC) visit and at the third trimester were 20.8% and 44.9%, respectively. The rate of IFA supplementation compliance during pregnancy was 80.1%. Forgetfulness (66.9%) was the major reason for non-compliance, followed by side effects (15.7%). Maternal employment [OR (95%CI): 1.7 (1.00-2.89)], history of a low birth weight infant [OR (95%CI): 0.4 (0.19-0.9)] and history of anaemia [OR (95%CI): 0.4 (0.12-0.98] were significantly associated with maternal compliance with IFA supplementation. Only 26.6% of the participants adhered to dietary recommendations during the period when IFA supplements were provided. The rate of maternal compliance with IFA supplementation was high. However, the prevalence of maternal anaemia during pregnancy was also high, which was presumably due to poor dietary compliance despite high IFA supplementation compliance.

Project description:BACKGROUND:Despite the supplementation of iron-folic acid is the recommended strategy during the antenatal period; iron deficiency anemia is the commonest hematologic complication during pregnancy. Therefore, this systematic review and meta-analysis aimed to assess the level of adherence to iron-folic acid supplementation and its associated factors among pregnant women in Ethiopia. METHODS:Systematic review and meta-analysis guideline was followed for this study. Different online databases were used for the review: PubMed, HINARI, EMBASE, Google Scholar and African Journals Online. Different searching terms were applied based on the adapted PICO principles to achieve and access all the essential articles. The data were entered and analyzed using Microsoft Excel and Stata 11 software respectively. RESULTS:Fifteen studies were included in this systematic review and meta-analysis with a total of 5808 pregnant women. The overall pooled prevalence of adherence to iron-folic acid supplementation among pregnant women in Ethiopia was 41.38% (95% CI: 33.09, 49.67). Having secondary and above educational status of the women (AOR:2.68,95%CI:1.25, 5.74), having an early registration of antenatal care follow-up (?16?weeks) (AOR:2.54,95%CI:1.99, 3.24), having anemia complication during current pregnancy (AOR:3.01,95%CI:1.88, 4.81), having good knowledge of iron-folic acid supplementation (AOR: 2.96, 95%CI:1.76, 4.99), having four times or more antenatal care follow up (AOR:3.66, 95%CI:2.81, 4.77), getting health education about benefit of iron and folic acid (AOR:2.62,95%CI:1.46,4.72), and having good knowledge about anemia (AOR:2.99,95%CI:2.32, 3.85) were associated risk factors for adherence to iron-folic acid supplementation. CONCLUSION:The overall pooled prevalence adherence of IFAS among pregnant women was lower than the WHO recommendations. Educational status, early registration of ANC, anemia in the current pregnancy, good knowledge of IFAS, number of ANC visits, good knowledge of anemia and receiving health education about the benefit of IFAS were factors associated with the adherence of IFAS among pregnant women in Ethiopia. This finding is important to design strategic policies and to prevent anemia and congenital anomaly resulted from inadequate intake of iron and folic acid.

Project description:UnlabelledChild eating behaviors play an important role in nutrient intake, ultimately affecting child growth and later outcomes in adulthood. The study assessed the effects of iron-folic acid and zinc supplementation on child temperament and child eating behaviors in rural Nepal. Children (N = 569) aged 4-17 months in Sarlahi district, southern Nepal were randomized to receive daily supplements of placebo, iron-folic acid, zinc, or zinc plus iron-folic acid and followed for approximately 1 year. At baseline and four follow-up visits mothers completed questionnaires including information on demographic characteristics and child temperament and eating behaviors. The main effects of zinc and iron-folic acid supplementation on temperament and eating behaviors were assessed through crude and adjusted differences in mean cumulative score changes between visits 1 and 5. The adjusted rate-of-change for these outcomes was modeled using generalized estimating equations. Mean changes in temperament scores and in eating behavior scores between visits 1 and 5 were not significant in either the zinc or non-zinc group. Children in the iron-folic acid group increased temperament scores by 0.37 points over 5 visits (95% CI 0.02, 0.7), which was not significant after adjustment. Neither the adjusted rate-of-change in temperament scores between zinc and non-zinc (? = -0.03, 95% CI -0.3, 0.2) or iron-folic acid and non-iron-folic acid (? = 0.08, 95% CI -0.2, 0.3) were significantly different. Adjusted rate of change analysis showed no significant difference between zinc and non-zinc (? = -0.14, 95% CI -0.3, 0.04) or between iron and non-iron eating behavior scores (? = -0.11, 95% CI -0.3, 0.1). Only among children with iron-deficiency anemia at baseline was there a significant decrease in eating behavior score, indicating better eating behaviors, when supplemented with zinc (? = -0.3, 95% CI -0.6, -0.01), Ultimately, this effect of zinc on eating behaviors was the only effect we observed after approximately one year of micronutrient supplementation.Trial registrationClinicalTrials.gov NCT00109551.

Project description:In Nepal, antenatal iron-folic acid supplementation improved aspects of intellectual, executive, and fine motor function among school-age children. We examined the impact of added zinc to the maternal antenatal supplement (M-IFAZn) and preschool supplementation from 12 to 36 mo with iron-folic acid (C-IFA) ± zinc (C-IFAZn) on cognitive outcomes compared to maternal iron-folic acid (M-IFA) alone. Children 7-9 y old (n = 780) who participated in early childhood micronutrient supplementation trial during 2001-2004 and whose mothers participated in an antenatal micronutrient supplementation between 1999 and 2001 were followed for cognitive assessments in 2007-2009. Using multivariate analysis of variance and adjusting for confounders, M-IFA with child supplementation (either C-IFA or C-IFAZn) did not impact scores on the tests of general intelligence (Universal Nonverbal Intelligence Test), and executive function (Stroop and go/no go tests) relative to the M-IFA alone. However, children in the C-IFAZn group had slightly lower scores on the backward digit span (-0.29, 95% CI: -0.55, -0.04) and Movement Assessment Battery for Children (1.33, 95% CI: 0.26, 2.40) relative to the referent group, whereas both C-IFA (-1.92, 95% CI: -3.12, -0.71) and C-IFAZn (-1.78, 95% CI: -2.63, -0.92) produced somewhat lower finger tapping test scores (fine motor skills). The combination of M-IFAZn and C-IFA or C-IFAZn did not lead to any outcome differences relative to M-IFA alone. Preschool iron-folic acid ± zinc to children exposed to iron-folic acid in utero or addition of zinc to maternal iron-folic acid conferred no additional benefit to cognitive outcomes assessed in early school age. The late timing of supplementation during preschool may explain the lack of impact of iron and/or zinc.

Project description:IntroductionIron deficiency is widespread in the developing world and is especially common in young children who live on the Indian subcontinent. Supplementation with iron and folic acid alleviates severe anaemia and enhances neurodevelopment in deficient populations, but little is known about the risks of mortality and morbidity associated with supplementation.MethodsWe did a community-based, cluster-randomised, double-masked, placebo-controlled, 2x2 factorial trial in children aged 1-36 months and residing in southern Nepal. We randomly assigned children daily oral supplementation to age 36 months with: iron (12.5 mg) and folic acid (50 microg; n=8337), zinc alone (10 mg), iron, folic acid, and zinc (n=9230), or placebo (n=8683); children aged 1-11 months received half the dose. Our primary outcome measure was all-cause mortality, and our secondary outcome measures included cause-specific mortality and incidence and severity of diarrhoea, dysentery, and acute respiratory illness. Analyses were by intention to treat. This study is registered at , number NCT00109551.FindingsThe iron and folic acid-containing groups of the study were stopped early in November, 2003, on the recommendation of the data and safety monitoring board; mortality in these groups did not differ from placebo and there was low power to detect positive or negative effects by the time enrollment was completed. We continued to enroll children to the placebo and zinc alone groups. 25,490 children participated and analyses are based on 29,097.3 person-years of follow-up. There was no difference in mortality between the groups who took iron and folic acid without or with zinc when compared with placebo (HR 1.03, 95% CI 0.78-1.37, and 1.00, 0.74-1.34, respectively). There were no significant differences in the attack rates for diarrhoea, dysentery, or respiratory infections between groups, although all the relative risks except one indicated modest, non-significant protective effects.InterpretationDaily supplementation of young children in southern Nepal with iron and folic acid with or without zinc has no effect on their risk of death, but might protect against diarrhoea, dysentery, and acute respiratory illness.
