Using a systematic review method, the prevalence of anaemia, iron deficiency (ID), and iron deficiency anaemia (IDA) in women of reproductive age (WRA) and children under 5 years of age was obtained to inform priorities in health planning and policy in South Africa. We searched electronic databases for articles published between 1997 and 2021. A total of 713 articles were identified, of which 14 articles comprising 9649 WRA and 4085 children were included. Since most of the included studies were of low quality, we did not pool data in a meta-analysis due to heterogeneity (I2 > 75%). In WRA, anaemia prevalence ranged from 22.0% to 44.0%; ID from 7.7% and 19.0%; and IDA from 10.5% to 9.7%. The prevalence of anaemia in pregnancy was 29.0% to 42.7%; and 60.6% to 71.3% in HIV-infected pregnant women. Three national surveys reported anaemia in children at 28.9%, 10.7%, and 61.3%, respectively. Overall, among the children under 5 years old, anaemia was more prevalent in 1-year-olds (52.0%) compared to the other age groups. Between 2005 and 2012, ID increased by 3.8% and IDA decreased by 83.2% in children. Anaemia in WRA and children under 5 years in South Africa was a moderate public health concern. Therefore, interventions addressing anaemia should be intensified, and policies on iron supplementation and food fortification need to be revised and aligned to the WHO multiple micronutrient supplementation recommendations.

BackgroundIron-deficiency anaemia disproportionately affects children in low-income and middle-income areas; Western China is a prime example. Given the health risks associated with childhood anaemia and the large heterogeneity of published studies on this subject, we conducted a systematic review of the evidence regarding anaemia prevalence and associated factors in children under 5 years in Western China.MethodsWe searched for all relevant studies on the prevalence of iron deficiency anaemia in children under 5 years in Western China, obtaining research between 1 January 2011 and 30 June 2021, in English and Chinese from Medline, Embase, PubMed, Web of Science, CNKI, WanFang Data and VIP. Two reviewers independently screened titles and abstracts; three reviewed full texts of relevant articles for data extraction and performed quality assessments. The median prevalence was calculated on unweighted pooling, stratified by region, sex, age and ethnic group. Associated factors and a linear trend chart were conducted to identify trends and research highlights.ResultsAmong the 55 articles included, most were cross-sectional studies (39, 70.91%). The prevalence of anaemia in children under 5 years in Western China ranged from 3.69% to 75.74% (median 42.54% (IQR 25.62%–52.56%)); the highest levels were in Qinghai province: 59.10%–75.74% (median 67.80% (IQR 64.70%–72.75%)); the highest levels were reported in the subgroup of children aged 6–12 months (median 50.09% (IQR 34.35%–59.04%)). Regional contexts, individual sociodemographic characteristics and feeding behaviours, and nutritional programme interventions were factors associated with anaemia prevalence.ConclusionThe prevalence of anaemia in children under 5 years in Western China is concerningly high. For this multiethnic and economically underdeveloped region, more high-quality and prospective studies are needed to inform evidence based and targeted preventive strategies to decrease the high prevalence of anaemia among young children.

AbstractObjectiveTo quantify the potential effect of iron defortification in the USA on iron-deficiency anaemia (IDA).MethodsMonte Carlo models were built to simulate iron nutrition in the US population. A hypothetical cohort of 15 000 persons from the general population was used in 15-year simulations to compare the prevalence of IDA with and without fortification.ResultsWith iron fortification, the prevalence of IDA was 2.4% for children aged 3–5 years, 5.4% for women aged 20–49 years, and 0.14% for men aged 20–49 years. The corresponding IDA estimates under iron defortification were 4.5%, 8.2% and 0.46%, respectively. Defortification had little effect on the distribution of iron indicators at or above the 50th percentile within each of these three groups and little effect on the distributions of iron indicators among adult men.ConclusionIron defortification is likely to increase IDA among children and women of reproductive age, but is not likely to have meaningful effects on the iron status of men or the majority of women and children.

ObjectiveTo conduct a systematic review to investigate the safety of induction and/or augmentation of labour compared with spontaneous-onset normal labour among pregnant women with iron-deficiency anaemia.DesignSystematic review.SettingStudies from all countries, worldwide.PopulationPregnant women with iron-deficiency anaemia at labour and delivery.InterventionAny intervention related to induction and/or augmentation of labour.Outcome measuresPrimary: Postpartum haemorrhage (PPH), heart failure and maternal death. Secondary: Emergency caesarean section, hysterectomy, admission to intensive care unit.MethodWe searched 10 databases, including Medline and Embase, from database inception to 1 October 2018. We included all study designs except cross-sectional studies without a comparator group, case reports, case series, ecological studies, and expert opinion. The searches were conducted by a healthcare librarian and two authors independently screened and reviewed the studies. We used the Grading of Recommendations, Assessment, Development and Evaluations (GRADE) approachto ascertain risk of bias and conducted a narrative synthesis.ResultsWe identified 3217 journal articles, 223 conference papers, 45 dissertations and 218 registered trials. Ten articles were included for full-text review and only one was found to fulfil the eligibility criteria. This was a retrospective cohort study from India, which showed that pregnant women with moderate and severe anaemia could have an increased risk of PPH if they underwent induction and/or augmentation of labour, but the evidence was weak (graded as ‘high risk of bias’).ConclusionThe best approach is to prevent anaemia, but a large number of women in low-to-middle-income countries present with severe anaemia during labour. In such women, appropriate peripartum management could prevent complications and death. Our review showed that at present we do not know if induction and augmentation of labour is safe in pregnant women with iron-deficiency anaemia and further research is required.PROSPERO registration numberCRD42015032421.

IntroductionSickle cell disease (SCD) is the most common inherited disease worldwide. The greatest disease burden is seen in sub-Saharan Africa. Early diagnosis and improved care of people living with SCD have led to an increase in the number of women with SCD reaching the reproductive age. Iron deficiency anaemia remains the most common cause of anaemia in pregnancy, affecting 51%–63% of pregnancies in Africa. However, the unavailability of guidelines on supplementation of iron in this pregnant subpopulation often leaves clinicians in a fix. We propose to conduct the first systematic review and possibly a meta-analysis on the prevalence, associated factors and maternal/fetal outcomes of iron deficiency anaemia among pregnant women with SCD.Methods and analysisWe will search the following electronic databases for studies on the iron status of pregnant women with SCD: PubMed, MEDLINE, EMBASE, Google Scholar, African Journals Online, African Index Medicus, Popline and the Cochrane Library. After the selection of eligible studies from the search output, review of full text, data extraction and data synthesis will be performed. Studies obtained from the review shall be evaluated for quality, risk of bias and heterogeneity. Appropriate statistical methods shall be used to pool prevalence estimates for matching studies globally and in subpopulations. This protocol has been reported as per the 2015 guidelines of the Preferred Reporting Items for Systematic Review and Meta-Analysis Protocols.Ethics and disseminationThere is no requirement for ethical approval as the proposed study will use published data. The findings of this study will be published in a peer-reviewed journal and will be presented at conferences.Trial registration numberCRD42018109803.

Introduction: Iron Deficiency Anaemia (IDA) is the most widespread micronutrient deficiency. Globally, nearly two billion people are affected by anaemia. This disease most often affects children, women of child-bearing age, and pregnant women. Nearly half of the pregnant women in the world are estimated to be anaemic. Its prevalence varies according to region and socio-economic conditions. The majority of those who are anaemic live in developing countries where the problem is exacerbated by limited access to inadequate resources and appropriate treatment. Aim: To find out the prevalence of IDA in the reproductive age group women and its associated factors. Materials and Methods: This hospital based, cross-sectional study was conducted among 400 females, of age group 15-49 years. After obtaining the written informed consent, eligible subjects were inquired about socio-demographic variables, socio-economic status, anthropometric measurements and risk factors. Required investigations were done. All the information was recorded on the semi-structured schedule form. Chi-square/Fisher’s-exact test was used to find the significance of study parameters on categorical scale between two or more groups. Results: Prevalence of IDA was found to be 42% (168/400). Prevalence of IDA was significant with habitat (p=0.0180), exercise (p=0.0004), amount of blood loss during menstruation (p<0.0001), duration of flow during menstruation, (p=0.0020), consumption of fish (p=0.0002), consumption of legumes (p=0.002), consumption of green leafy vegetable (p<0.0001). Conclusion: Results confirmed an increased prevalence of IDA in women of reproductive age group.

Introduction: Iron deficiency anaemia is an international public health concern and pregnant women are at an increased risk. We investigated the consumption of iron rich foods and associated factors among pregnant women in a rural district from Ghana. Methods: Following a cross-sectional design, dietary intake of iron rich foods was obtained from 252 pregnant women using a 24-hour recall food check list. Nutrition knowledge, attitudes and socio-demographic characteristics were also assessed. Findings: Participants had a mean (SD) knowledge score of 54.66 (22.74)%. About 73% of the participants had heard about iron-deficiency anaemia. Only 16.3% of the participants knew foods that help the body to absorb and use iron while 9.1% knew beverages that decrease iron absorption. About 71% of the participants ate fish and/or seafood while 67.1% of them ate green leafy vegetables. Only 4.4% of the participants ate organ meat, and 29% took flesh meat. Only 22.4% of the study participants usually drank coffee or tea while 78.2% ate vitamin C-rich foods. With regards to attitudes, 88.5% of the participants perceived anaemia to be a serious disease. Nutrition knowledge was significantly associated with the consumption of iron rich foods (β = .02; 95% CI = 0.01-0.02). Conclusion: Nutrition knowledge may be an important determinant of the consumption of iron rich foods among pregnant women making it necessary for healthcare providers to continue to provide nutrition education to pregnant women during routine antenatal care.
