National Iron Plus Initiative: Current status & future strategy

Maternal anaemia prevention and control in China: A policy review

Maternal anaemia is a major public health problem. Developing maternal anaemia prevention and control policies is an important prerequisite for carrying out evidence-based interventions. This article reviews maternal anaemia prevention and control policies in China, identifies gaps, and provides references for other countries. We examined policies concerning maternal nutrition and other related literature in China, identified through key databases and government websites, and conducted a narrative review of the relevant documentations guided by the Smith Policy-Implementing-Process framework. A total of 65 articles and documents were identified for analysis. We found that Chinese government has committed to reducing maternal anaemia at the policy level, with established objectives and a clear time frame. However, most of policies were not accompanied by operational guidelines, standardized interventions, and vigorous monitoring and evaluation mechanisms, and 85% of the policies don't have quantifiable objectives on anaemia. Maternal anaemia prevention and control services offered in clinical settings were primarily nutrition education and anaemia screening. Population-based interventions such as iron fortification have yet to be scaled up. Furthermore, medical insurance schemes in some regions do not cover anaemia prevention and treatment, and in other regions that offer coverage, the reimbursement rate is low. The number and capacity of health professionals is also limited. Policy changes should focus on the integration of evidence-based interventions into routine antenatal care services and public health service packages, standardization of dosages and provision of iron supplementation, streamline of reimbursement for outpatient expenses, and capacity building of health professionals.

The prevalence of anemia during pregnancy and its correlates vary by trimester and hemoglobin assessment method in Eastern Maharashtra, India

Approximately half of pregnant women in India are anemic, representing over 7.5 million women. Few studies have assessed the relationship between multiple micronutrient deficiencies and anemia during pregnancy or the trajectory of hemoglobin (Hb) during pregnancy in low-resource settings. We enrolled 200 pregnant women from the Maternal and Newborn Health (MNH) registry, a population-based pregnancy and birth registry in Eastern Maharashtra, India to address these gaps. The women provided capillary (finger-prick) and venous blood specimens at enrollment (<15 weeks), and a second capillary specimen in the 3rd trimester (>27 weeks). Capillary specimens were analyzed at the time of collection with a HemoCue Hb 201+; venous specimens were shipped on dry ice to a laboratory for cyanmethemoglobin assessment. In the 1st trimester, mean Hb concentration and anemia (Hb<11.0 g/dL) prevalence using capillary specimens were 10.9 ± 1.5 g/dL and 51.1%; mean Hb concentration using venous blood specimens was estimated to be 11.3 ± 1.3 g/dL and anemia prevalence was 37.5%. The prevalence of iron, vitamin B12 and folate deficiencies were 40%, 30% and 0%, respectively. Among women with anemia in the 1st trimester (venous blood), 56% had concurrent iron deficiency (inflammation-adjusted serum ferritin <15 µg/L) indicating that their anemia may be amenable to iron supplementation. In total, 21% of women had ID and anemia, 19% ID in the absence of anemia, 16.5% anemia in the absence of ID and 43.5% had neither. By the 3rd trimester, mean Hb from capillary specimens had declined to 10.1 ± 1.35 g/dL and anemia prevalence increased to 70.7%, despite 99.4% mothers reporting receipt of iron-folic acid (IFA) supplements during her current pregnancy, and 83.9% reporting IFA consumption the previous day. Significant predictors of anemia in the 1st trimester (both venous and capillary) included the number of weeks gestation at the time of Hb assessment and inflammation-adjusted serum ferritin. For 3rd trimester anemia, significant predictors included 1st trimester height, BMI and IFA consumption during the 3rd trimester (but not 1st trimester micronutrient biomarkers), indicating that IFA supplementation over the course of pregnancy may have influenced micronutrient status and anemia risk. Our findings highlight the severity of the burden of anemia and micronutrient deficiencies in Eastern Maharashtra, but also highlight that in many cases, ID and anemia affect different individuals. Preventing and managing anemia in pregnancy in India will require strengthening both clinical and community-based strategies targeting iron deficiency, as well as other causes of anemia.

Risk factors for labour induction and augmentation: a multicentre prospective cohort study in India

Background

Guidelines for labour induction/augmentation involve evaluating maternal and fetal complications, and allowing informed decisions from pregnant women. This study aimed to comprehensively explore clinical and non-clinical factors influencing labour induction and augmentation in an Indian population.

Methods

A prospective cohort study included 9305 pregnant women from 13 hospitals across India. Self-reported maternal socio-demographic and lifestyle factors, and maternal medical and obstetric histories from medical records were obtained at recruitment (≥28 weeks of gestation), and women were followed up within 48 h after childbirth. Maternal and fetal clinical information were classified based on guidelines into four groups of clinical factors: (i) ≥2 indications, (ii) one indication, (iii) no indication and (iv) contraindication. Associations of clinical and non-clinical factors (socio-demographic, healthcare utilisation and lifestyle related) with labour induction and augmentation were investigated using multivariable logistic regression analyses.

Findings

Over two-fifths (n = 3936, 42.3%, 95% confidence interval [CI] 41.3-43.3%) of the study population experienced labour induction and more than a quarter (n = 2537, 27.3%, 95% CI 26.4-28.2%) experienced augmentation. Compared with women with ≥2 indications, those with one (adjusted odds ratio [aOR] 0.50, 95% CI 0.42-0.58) or no indication (aOR 0.24, 95% CI 0.20-0.28) or with contraindications (aOR 0.12, 95% CI 0.07-0.20) were less likely to be induced, adjusting for non-clinical characteristics. These associations were similar for labour augmentation. Notably, 34% of women who were induced or augmented did not have any clinical indication. Several maternal demographic (age at labour, parity and body mass index in early pregnancy), healthcare utilization (number of antenatal check-ups, duration of iron-folic acid supplementation and individuals managing childbirth) and socio-economic factors (religion, living below poverty line, maternal education and partner's occupation) were independently associated with labour induction and augmentation.

Interpretation

Although decisions about induction and augmentation of labour in our study population in India were largely guided by clinical recommendations, we cannot ignore that more than a third of the women did not have an indication. Decisions could also be influenced by non-clinical factors which need further research.

Quantifying the Occurrence of High-Risk Pregnancy: A Comprehensive Survey

Background High-risk pregnancies are characterized by various factors that pose potential risks to maternal and newborn health outcomes. Early detection of these high-risk pregnancies serves as a crucial initial step in preventing maternal mortality and morbidity, thereby promoting the overall health of both mother and baby. This study sought to assess the occurrence of high-risk pregnancy and investigate the factors associated with it among pregnant women. Methods A descriptive survey was undertaken at the Obstetrics and Gynaecology outpatient department of a District Government Hospital in Tamil Nadu, involving 1889 pregnant women in their second and third trimesters. A structured questionnaire, constructed following the Indian standard criteria outlined by the National Health Portal of India, served as the data collection tool. The survey was conducted in February and March 2022, during which pregnant women were interviewed. Subsequently, the collected data underwent descriptive and inferential statistical analysis. Results Among the 1889 pregnant women surveyed, 29% (n=530) were classified as high-risk pregnancies. Within this group, 34.3% (n=182) were diagnosed with hypothyroidism, while 23.2% (n=123) experienced pregnancy-induced hypertension. Significant associations with high-risk pregnancy were observed for factors such as age, education status, occupation, family income, socioeconomic status, and gravida among the pregnant women. Conclusion Policymakers must urgently implement evidence-based interventions aimed at early detection and treatment of high-risk pregnancies. This proactive approach is essential in preventing maternal mortality and morbidity.

Study of anaemia in pregnancy and low birth weight in fluoride endemic area of Western Rajasthan: a cohort study

Background

Fluoride is a noxious element known to destroy gastrointestinal mucosa, leading to erythrocytes' destruction and causing anaemia. The birth weight of newborn babies is a significant indicator of a child's vulnerability to the risk of childhood diseases and chances of existence.

Methods

This prospective cohort study was planned to find linkages between fluorosis and the low-birth weight of newborn babies with anaemic mothers. Antenatal mothers until the 20th week of gestation were followed up till delivery in the Antenatal Clinic of a District Hospital in one of the known fluoride-endemic districts (Nagaur) and the other not-so-endemic district (Jodhpur) of Western Rajasthan.

Results

Around 19% of the newborn in Jodhpur and around 22% in Nagaur had low birth weight. Mean fluoride values in water samples were measured to be 0.57 (range from 0.0 to 2.7 PPM) in Jodhpur and 0.7 (range from 0.0 to 3.4 PPM) in Nagaur.

Conclusions

Thus, in fluoride endemic areas, other factors should be included besides iron and folic acid supplementation for improving anaemia in pregnant women. This calls for assessing the effectiveness of de-fluoridation activities along with the area's most common indigenous food practices.

Prevalence and determinants of anaemia among women of reproductive age in Aspirational Districts of India: an analysis of NFHS 4 and NFHS 5 data

BACKGROUND

Over one-third of women worldwide suffer from anaemia. The prevalence of anaemia is particularly pronounced among women of reproductive age (WRA) in developing countries, such as India. No prior study has ever exclusively studied the prevalence of anaemia across the Aspirational Districts of India. Therefore, the purpose of this study was to examine the prevalence of anaemia across Aspirational Districts of India and to identify the determinants of anaemia among WRA in these districts.

METHODS

From the National Family Health Survey (NFHS)-4 (2015-16) and NFHS-5 (2019-21), data on 114,444 and 108,782 women aged 15-49 from Aspirational Districts were analyzed in our study, respectively. Bivariate statistics and multivariable binary logistic regression were used to identify the determinants of anaemia.

RESULTS

The national prevalence of anaemia among WRA has increased from 53% in NFHS-4 to 57% in NFHS-5 whereas anaemia among WRA in Aspirational Districts has increased from 58.7% in NFHS-4 to 61.1% in NFHS-5. Between 2015 and 2021, over 60% of Aspirational Districts experienced an increase in the prevalence of anaemia and one-fourth, specifically 29 out of 112, observed a rise by at least 10 percentage points (pp). Notably, there are significant variations in anaemia prevalence among districts, with Simdega and Udalgiri having the highest anaemia prevalence in NFHS-4 and NFHS-5 at 78.2% and 81.5%, respectively. During this period, Barpeta followed by Udalgiri of Assam have witnessed the maximum increase with 29.4% and 26.7% respectively. Moreover, pooled regression results show women with three to four children [AOR: 1.13, 95% CI: 1.08-1.17], women who breastfeed [AOR: 1.17, 95% CI: 1.13-1.20], Scheduled Tribe women [AOR: 1.39, 95% CI: 1.35-1.44], poorest women [AOR: 1.27, 95% CI: 1.22-1.33] and women those who consume fish occasionally [AOR: 1.14, 95% CI: 1.12-1.17] were more likely to be anaemic.

CONCLUSION

The significant increase in anaemia among WRA in Aspirational Districts of India is a matter of concern. Given the rise in anaemia among WRA, determinants-based and district-specific measures must be designed and implemented to reduce the prevalence of anaemia among Aspirational Districts of India.

Pre-term labour: A study on evaluation of causes and outcome

Background

Despite recent advances in medicine, the incidence of pre-term birth is increasing globally. Approximately 70% of neonatal deaths, 36% of infant deaths, and 25-50% of cases of neurological impairment in children can be attributed to pre-term births. Identification of risk factors in women, supervised obstetric care during pregnancy, female empowerment, and patient education are strategies to minimize the burden of preterm deliveries.

Materials and Methods

A prospective cross-sectional study was conducted over a 1-year period among 658 women in the Department of Obstetrics and Gynecology, Pramukhswami Medical College, Anand, Gujarat. Detailed history, general, and obstetrical examinations were carried out. Maternal and foetal outcomes were noted. Statistical software STATA 14.2 was used for data analysis.

Results

The incidence of pre-term birth in our study was 34.95%. The incidence of late pre-term, very term, and extremely pre-term was 28.42%, 4.71%, and 1.82%, respectively. Pre-mature rupture of the membrane was observed among 20.34% of patients with late pre-term labour. IUGR was identified in 9.52% and 15.94% of the very and late pre-term births, respectively. A statistically significant difference was found in the 1 minute and 5 minute Apgar scores between pre-term babies and term babies.

Conclusion

Pre-maturity is a huge health and financial burden in rural and semi-urban central Gujarat. Pre-mature rupture of membranes, previous MTP, extreme physical activity, and maternal anaemia were the major risk factors linked with pre-term labour. Poor neonatal outcomes like LBW, IUGR, and a low Apgar score were significantly associated with the babies delivered pre-mature in our study.

Anemia Prevalence and Socioeconomic Status among Adolescent Girls in Rural Western India: A Cross-Sectional Study

Background

Anemia poses a significant challenge among Indian adolescent girls due to their heightened vulnerability, resulting from increased micronutrient requirements, rapid physical growth, menstrual blood loss, inadequate nutrition, and socioeconomic disparities. This study sought to evaluate the prevalence of anemia, along with socioeconomic and nutritional statuses among adolescent girls attending rural public schools in Pune, India.

Methods

A sample of 400 girls was selected from 22 villages through Symbiosis International University. Hemoglobin levels were assessed using the HemoCue 201 system, while standardized protocols were employed for height, weight, and BMI-for-age measurements. Socioeconomic status was determined using the Kuppuswamy scale.

Results

The findings revealed an overall anemia prevalence of (42.75%), comprising severe (2.5%), moderate (21%) and mild (20.25%) cases. Additionally, a substantial proportion (74.6%) of girls were classified as underweight. Socioeconomic analysis disclosed that 64.25% of families belonged to the lower middle class, and 27% in the upper lower class. Anemia was more prevalent in young adolescent girls (10-14 years) and in the families of adolescents who had low income, were illiterate, unemployed, and belonged to the lower-middle class and upper-lower-class socio-economic status (SES) and did not have a bank account.

Conclusion

Anemia was prevalent in adolescent girls and associated with low SES. This study underscores the limitations of relying solely on the distribution of iron and folic acid tablets to combat anemia. A holistic strategy is imperative, encompassing improvements in SES of families (literacy, employment and income), as well as initiatives aimed at enhancing the nutritional status of adolescent girls.

Prevention and Management of Iron Deficiency/Iron-Deficiency Anemia in Women: An Asian Expert Consensus

The lack of standardized clinical practice impeding the optimal management of iron deficiency (ID) and iron deficiency anemia (IDA) in women is a global concern, particularly in the Asia-Pacific region. The aim of this study was to determine best practices through a Delphi consensus process. In Round 1, panelists were asked to rate their level of agreement with 99 statements across four domains: identification, diagnosis and assessment, prevention, and treatment of ID/IDA in women. In Round 2, panelists reappraised their ratings in view of the collective feedback and responses to Round 1. After two rounds, consensus (≥85% agreement) was reached for 84% of the Delphi statements. Experts agreed on the role of presenting symptoms and risk factors in prompting assessments of anemia and iron status in women. Experts repeatedly called for prevention, recommending preventive iron supplementation for pregnant women irrespective of anemia prevalence levels, and for non-pregnant adult women, adolescent girls, and perimenopausal women living in areas with a high prevalence of anemia. Experts unanimously agreed to prescribing oral ferrous iron as first-line therapy for uncomplicated ID/IDA. The recommendations and clinical pathway algorithms generated should be used to inform clinical practice and standardize the care of women at risk or presenting with ID/IDA in the Asia-Pacific region.

Predictive association of gut microbiome and NLR in anemic low middle-income population of Odisha- a cross-sectional study

Background

Iron is abundant on earth but not readily available for colonizing bacteria due to its low solubility in the human body. Hosts and microbiota compete fiercely for iron. <15% Supplemented Iron is absorbed in the small bowel, and the remaining iron is a source of dysbiosis. The gut microbiome signatures to the level of predicting anemia among low-middle-income populations are unknown. The present study was conducted to identify gut microbiome signatures that have predictive potential in association with Neutrophil to lymphocytes ratio (NLR) and Mean corpuscular volume (MCV) in anemia.

Methods

One hundred and four participants between 10 and 70 years were recruited from Odisha's Low Middle-Income (LMI) rural population. Hematological parameters such as Hemoglobin (HGB), NLR, and MCV were measured, and NLR was categorized using percentiles. The microbiome signatures were analyzed from 61 anemic and 43 non-anemic participants using 16 s rRNA sequencing, followed by the Bioinformatics analysis performed to identify the diversity, correlations, and indicator species. The Multi-Layered Perceptron Neural Network (MLPNN) model were applied to predict anemia.

Results

Significant microbiome diversity among anemic participants was observed between the lower, middle, and upper Quartile NLR groups. For anemic participants with NLR in the lower quartile, alpha indices indicated bacterial overgrowth, and consistently, we identified R. faecis and B. uniformis were predominating. Using ROC analysis, R. faecis had better distinction (AUC = 0.803) to predict anemia with lower NLR. In contrast, E. biforme and H. parainfluenzae were indicators of the NLR in the middle and upper quartile, respectively. While in Non-anemic participants with low MCV, the bacterial alteration was inversely related to gender. Furthermore, our Multi-Layered Perceptron Neural Network (MLPNN) models also provided 89% accuracy in predicting Anemic or Non-Anemic from the top 20 OTUs, HGB level, NLR, MCV, and indicator species.

Conclusion

These findings strongly associate anemic hematological parameters and microbiome. Such predictive association between the gut microbiome and NLR could be further evaluated and utilized to design precision nutrition models and to predict Iron supplementation and dietary intervention responses in both community and clinical settings.

Trends in prevalence and determinants of severe and moderate anaemia among women of reproductive age during the last 15 years in India

BACKGROUND

Anaemia is a serious global public health problem that disproportionally affects children, adolescent girls, and women of reproductive age, especially pregnant women. Women of reproductive age are more vulnerable to anaemia, particularly severe and moderate anaemia leads to adverse outcomes among pregnant women. Despite continuous Government efforts, anaemia burden still poses a serious challenge in India. The objective of this study is to assess the trends in prevalence and determinants of severe and moderate anaemia among women of reproductive age between 15 and 49 years.

METHOD

We used three rounds of the large-scale National Family Health Survey (NFHS) India, conducted on a representative sample of households using a cross-sectional design across the country in 2005-06, 2015-16 and 2019-2021. We included all the women aged 15 to 49 years in our analysis. We used the same haemoglobin (Hb) cut-off values for all the three rounds of surveys to ensure comparability. Generalized linear regression analyses with log link were done. Survey weights were incorporated in the analysis.

RESULTS

The prevalence of severe or moderate Anaemia (SMA) in non-pregnant women was 14.20%, 12.43% and 13.98%; it was 31.11%, 25.98% and 26.66% for pregnant women in 2006, 2016 and 2021 respectively. The decline in SMA prevalence was 1.54% in non-pregnant women, whereas it was 14.30% in pregnant women in 15 years. Women who were poor, and without any formal education had a higher risk for severe and moderate Anaemia.

CONCLUSION

Despite the intensive anaemia control program in India, SMA has not declined appreciably in non-pregnant women during the last two decades. Despite the decline, the prevalence of SMA was about 26% in pregnant women which calls for a comprehensive review of the existing anaemia control programmes and there must be targeted programmes for the most vulnerable and high-risk women such as rural, poor and illiterate women of reproductive age to reduce the burden of anaemia among them.

To what extent classic socio-economic determinants explain trends of anaemia in tribal and non-tribal women of reproductive age in India? Findings from four National Family Heath Surveys (1998-2021)

BACKGROUND

Despite unprecedented socio-economic growth experienced by Indians in the past few decades, and a long history of anti-anaemia public health measures, prevalence of anaemia in Indian non-pregnant women of reproductive age group (NPWRA) has not declined. This warrants a firm understanding of what explains the anaemia situation over time, preferably by sub-populations. Therefore, we aimed to examine the trends of anaemia in tribal NPWRA (least privileged) and compare with the trends in the NPWRA of general caste (most privileged) between 1998 to 2021. Additionally, the study also explored explanation of any decline and tribal/general narrowing of these trends.

METHODS

We studied four rounds of National Family Health Survey (1998-99, 2005-06, 2015-16, 2019-21). We examined the trend of anaemia (haemoglobin < 12 g/dl) and its possible determinants in tribal and general NPWRA and estimated the portion of "decline" and "narrowing" that could be explained by the underlying and intermediate determinants (wealth, education, residence, parity and food security) using multiple logistic regression.

RESULTS

The distribution of determinants improved over 23 years in both the groups but more in tribals. But anaemia either remained unchanged or increased in both except 7.1 points decline in tribals between 2006-2016, leading also to 7 points narrowing of tribal/general gap. The modest attenuation of beta coefficients representing the change of anaemia prevalence (log of odds) in tribals from -0.314(-0.377, -0.251) to -0.242(-0.308, -0.176) after adjustment with determinants could explain only 23% of the decline. Similarly, only 7% of the narrowing of the tribal/general anaemia gap could be explained.

CONCLUSIONS

The structural determinants wealth, education, food security, parity and urban amenities improved immensely in India but anaemia did not decline in this 23-year period. This implies that the "usual suspects" - the structural determinants are not the main drivers of anaemia in the country. The main driver may be absolute and/or functional deficiency status of micronutrients including iron attributable to inadequate uptake and absorption of these elements from Indian diets; and therefore, their effects are noticeable in every socio-economic stratum of India. Future research for aetiologies and new interventions for anaemia alleviation in India may focus on these factors.

Effect of Educational Handouts With Standard Therapy Versus Standard Therapy Alone on Compliance With Oral Iron Supplementation in Antenatal Women With Iron Deficiency Anemia: A Randomized Controlled Trial

Background Iron requirements rise dramatically throughout the second and third trimesters of pregnancy. Pregnant women are more susceptible to anemia because their need for iron increases during pregnancy, which is difficult to achieve through diet alone. Methodology A randomized controlled trial (non-blinded and parallel group) was undertaken with the recruitment of 174 women. However, 35 women were lost to follow-up, and the study was ultimately completed with 139 participants distributing 68 women in Group A (intervention group) and 71 women in Group B (non-interventional group). Educational handouts were explained to the participants with iron supplements in Group A and only supplements were given to Group B, and the participants were followed up till three months before the recruitment period. Compliance with iron supplementation and a rise in hemoglobin were noted. Results In this study, maximum women were in the 22-30 years age group and were almost evenly distributed with respect to parity with no statistically significant difference in the groups. All the participants were started with oral iron therapy. No additional parenteral iron therapy was given. Women in Group A showed good compliance for iron supplementation than those in Group B. It was determined that this difference was statistically insignificant (>0.05). In the majority of women, the reason for poor compliance was frustration to follow oral iron therapy daily (52.3% in Group A and 21.7% in Group B). There were other reasons like forgetfulness, heartburn, vomiting, constipation, and nausea as the reason for poor compliance. The hemoglobin levels were compared at the recruitment and a mean rise in hemoglobin levels was noted in groups A and B at the follow-up period after three months. There was a greater mean rise in hemoglobin concentration in Group A (1.28) than in Group B (0.63), which was statistically insignificant (>0.05). Conclusion The current study found that among pregnant women with iron-deficient anemia, instructional handouts did not promote compliance with oral iron treatment. The main reasons for low compliance were frustration with taking the oral drug, followed by forgetfulness, heartburn, vomiting, constipation, and nausea. In pregnant females with anemia brought on by iron deficiency, educational handouts did not enhance hemoglobin status.

Public health supply chain for iron and folic acid supplementation in India: Status, bottlenecks and an agenda for corrective action under Anemia Mukt Bharat strategy

PURPOSE

The IFA supplementation program under the Anemia Mukt Bharat (AMB) program is one of the most ambitious nutrient supplementation programs in India. The delivery of services often suffers due to frequent stock outs and shortages. It is critical to understand the bottleneck in the supply chain adversely affecting the performance and coverage of the program. The paper attempts to identify the bottlenecks of the IFA supply chain in key areas of supply chain i.e., forecasting, procurement, warehousing and inventory management, transportation, distribution, logistic information system and suggests a plan of action aimed at ensuring uninterrupted supplies to the end beneficiaries.

DESIGN/METHODOLOGY/APPROACH

The data source for the present paper is the nationwide IFA Supply Chain Assessment (2018-19) conducted across 29 Indian states with a total of 58 districts, 116 blocks, 232 Sub-Centres, 232 Anganwadi centres and 232 schools covered under the assessment as a multi-partner collaborative initiative. Field insights from supply chain strengthening interventions under different public health programs in India and other developing countries were taken to arrive at corrective actions and recommendations. Findings were disseminated to government and an action plan was suggested for connecting service delivery points through an app-based system, developing a micro plan for ensuring fixed distribution schedule, followed by continuous monitoring and review meetings identified for follow up.

FINDINGS

The average lead time across states was 35 weeks with top three performing states being Goa, Sikkim, and Telangana. The average per unit cost of procurement was Rs 0.35 for IFA Red, Rs 0.25 for IFA Blue, Rs 0.31 for IFA Pink and Rs 7.30 for IFA syrup. Out of the 704 districts in India, only 213 has IFA Red, only 140 had IFA Blue, 152 had IFA Pink and 163 had IFA Syrup available in four quarters of 2018-19. The key issues identified in the assessment were-a lack of standardized forecasting process, absence of inventory management techniques, no fixed distribution schedule, inadequate availability of transport vehicles and an absence of an integrated MIS.

ORIGINALITY/VALUE

The identification of bottlenecks in the IFA supply chain and its impact on the performance of the supply chain would provide policy guidelines for the government as well as development partner agencies to design an effective and efficient supply chain. It would also enable the policy planners to understand the challenges associated with managing different components of a supply chain, their interrelation and impact on the overall performance of the supply chain. The suggested recommendations would equip program managers with the tool to devise and implement field level solutions.

Shooting shadows: India's struggle to reduce the burden of anaemia

Despite several efforts by the Government of India, the national burden of anaemia remains high and its growing prevalence (between 2015-2016 and 2019-2021) is concerning to India's public health system. This article reviews existing food-based and clinical strategies to mitigate the anaemia burden and why they are premature and insufficient. In a context where multiple anaemia control programmes are in play, this article proposes a threefold strategy for consideration. First, except the Comprehensive National Nutrition Survey, 2016-2018, which measured Hb concentration among children and adolescents aged 1-19 years using venous blood samples, all national surveys use capillary blood samples to determine Hb levels, which could be erroneous. The Indian government should prioritise conducting a nationwide survey for estimating the burden of anaemia and its clinical determinants for all age groups using venous blood samples. Second, without deciding the appropriate dose of Fe needed for an individual, food fortification programmes that are often compounded with layering of other micronutrients could be harmful and further research on this issue is needed. Same is true for the pharmacological intervention of Fe tablet or syrup supplementation programmes, which is given to individuals without assessing its need. In addition, there is a dire need for robust research to understand both the long-term benefit and side effects of Fe supplementation programmes. Third and final, the WHO is in process of reviewing the Hb threshold for defining anaemia, therefore the introduction of new anaemia control programmes should be restrained.

Randomized Controlled Trial Comparing Ferrous Sulfate and Iron Sucrose in Iron Deficiency Anemia in Pregnancy

INTRODUCTION

 Anemia among pregnant women is one of the major health concerns for healthcare workers. The management becomes a concern in the pregnancy where the question arises of which is better the intravenous iron sucrose or the oral ferrous sulfate tablets. To answer this, a randomized control trial comparing both the treatment options in a tertiary care government hospital was set up in the hilly terrains of India. This study discusses the effectiveness and practical aspect of using both, which seems to be the better out of both, and why.

METHODS

 The study was conducted as a parallel-group, open-label randomized controlled trial (RCT) in the Department of Obstetrics and Gynecology of a tertiary care government hospital in India, with approximately 4,000 delivery loads annually. Ethical clearance was obtained from the institute's ethics committee (IEC), and the trial was registered with the Clinical Trial Registry of India (REF/2022/06/055013). Two hundred sixty-eight pregnant women between 18 and 45 years of age with moderate iron deficiency anemia (IDA) (hemoglobin (Hb) 7-9g/dl, microcytic-hypochromic, and serum ferritin <30ng/ml) were included in the study. Patients were randomly divided into two groups: group 1 with 134 patients to receive intravenous iron sucrose and group 2 with 134 patients to receive oral ferrous sulfate tablets.

RESULTS

The intravenous iron sucrose is superior in terms of tolerability and correction of iron deficiency anemia during pregnancy.

CONCLUSION

It yields a quicker rise in Hb and serum ferritin with no major side effects. In the difficult terrain of Himachal Pradesh, this makes IV iron sucrose a better option for anemic pregnant women who do not have easy access to health facilities resulting in a large number of them reaching hospitals with moderate to severe anemia at a later gestation.

Effect of Oral Iron Supplementation on Cognitive Function among Children and Adolescents in Low- and Middle-Income Countries: A Systematic Review and Meta-Analysis

BACKGROUND

There is abundant evidence showing that iron deficiency is closely linked with delayed brain development, worse school performance, and behavioral abnormalities. However, evidence on the impact of iron supplementation among children and adolescents in low- and middle-income countries (LMICs) has been inconsistent. This study aims to examine the effect of oral iron supplementation on cognitive function among children and adolescents in LMICs.

METHODS

A systematic review and meta-analysis was conducted to examine the impact of iron supplementation on cognitive function (including intelligence, attention, short-term memory, long-term memory, and school performance) among children and adolescents aged 5 to 19. We searched PubMed, Embase, Web of Science, CINAHL, and references of related articles published from the inception of the databases to 1 May 2022. Random-effects pooled standardized mean difference (SMD) with 95% confidence intervals (CIs) were calculated to estimate the effect of iron supplementation on cognitive function. We also investigated the heterogeneity of the effects using subgroup and meta-regression analyses. This review was registered with PROSPERO (CRD42020179064).

RESULTS

Nine studies with 1196 individual participants from five countries were identified and included. Iron had a positive impact on intelligence test scores among children and adolescents (SMD = 0.47, 95% confidence interval [CI]: 0.10, 0.83). Meta-regression showed that the intelligence test scores improved with increasing the iron supplement dose (odds ratio [CI] = 1.02, 95% CI: 1.00, 1.04). There were no significant effects on attention, short-term memory, long-term memory, or school performance.

CONCLUSIONS

Oral iron intake can improve the intelligence test scores of children and adolescents in LMICs and should be considered for future nutritional interventions.

Effects of a smartphone application on maternal health knowledge and dietary diversity among pregnant women in India: a randomized single center pilot study

Background

India contributes to one-fifth of infant and maternal deaths globally. Healthy lifestyles during pregnancy combined with good quality health care can help to avoid many maternal and neonatal deaths. Access to appropriate information is important for developing or maintaining a healthy lifestyle. The increased coverage of smartphones across low- and middle-income countries (LMICs) has given rise to smartphone apps supporting healthy pregnancies. The objective of this study is to evaluate the effects of the smartphone application Together For Her on maternal health knowledge and dietary diversity among pregnant Indian women.

Methods

We ran a randomised single-centre pilot study in a private hospital in Maharashtra, India. We randomly selected pregnant women at ≤20 weeks of gestation who were invited to download the application, in addition to regular antenatal care. The control group only received regular antenatal care. Knowledge about a healthy lifestyle during pregnancy, self-reported dietary diversity and individual characteristics were collected via telephone interviews at baseline (T0), midline (T0 + 4 weeks) and endline (T0 + 12 weeks).

Results

Complete data were collected for 179 respondents (intervention:94; control:85). Respondents in the intervention group showed larger increases in their knowledge over the 12-week study period, with an overall knowledge increase of 13.4 percentage points (P<0.001). The largest effects were found in the modules anaemia, breastfeeding and skin-to-skin contact. Self-reported diversity in nutritional intake also improved significantly more in the intervention group than in the control group.

Conclusions

Smartphone applications can effectively supplement antenatal care by increasing women’s knowledge about a healthy lifestyle during pregnancy, which is likely to reduce the risk of adverse maternal health outcomes. Future research includes the roll-out of a larger multi-centre RCT to assess the effect of the smartphone application on health outcomes.

Effectiveness of prophylactic iron supplementation in the reduction of recurrence of febrile seizures in children: A prospective study with comparison with historical controls

Objectives

The primary objective of the study was to compare the number of patients with febrile seizure recurrence within 1 year of presenting to our institute, among patients who received and didn't receive oral iron supplementation.

Materials and Methods

This prospective intervention study with historical controls was conducted to compare the number of patients with febrile seizure recurrence within 1 year, among patients who received and did not receive oral iron supplementation. The intervention group additionally received prophylactic iron supplementation of 20 mg biweekly for 1 year.

Results

A total of 53 patients each were enrolled in both the groups, with comparable baseline characteristics. Although there was a trend toward a lower rate of recurrence of febrile seizures in the interventional group, as compared to the control group, it did not reach the point of statistical significance (P = 0.35). Both in the worst-case scenario and best-case scenario, there was a trend toward less risk of recurrence of febrile seizure in the intervention group, but it did not reach the point of statistical significance (P = 0.43 and 0.52). For the original scenario, worst-case scenario, and best-case scenario, the absolute risk reduction was 6.5%, 7%, and 6%, respectively, with corresponding number needed to treat (NNT) being 15, 14, and 16, respectively. The trend for absolute risk reduction was more pronounced in those with complex febrile seizures with an NNT of 6.5, but it still did not reach the point of statistical significance (P = 0.16). Moderate/severe IDA was also found to be an independent risk factor for recurrence of febrile seizure in the intervention group (P = 0.03).

Conclusion

Oral serum iron supplementation does not significantly reduce the recurrence rate of febrile seizures in children aged 6-60 months. However, there is a trend toward reduction in the frequency of recurrence of febrile seizures, which is more pronounced in the subset with complex febrile seizures.

Iron Deficiency Anemia: Efficacy and Limitations of Nutritional and Comprehensive Mitigation Strategies

Iron deficiency anemia (IDA) has reached epidemic proportions in developing countries and has become a major global public health problem, affecting mainly 0–5-year-old children and young women of childbearing age, especially during pregnancy. Iron deficiency can lead to life-threatening loss of red blood cells, muscle function, and energy production. Therefore, the pathogenic features associated with IDA are weakness and impaired growth, motor, and cognitive performance. IDA affects the well-being of the young generation and the economic advancement of developing countries, such as India. The imbalance between iron intake/absorption/storage and iron utilization/loss culminates into IDA. However, numerous strategic programs aimed to increase iron intake have shown that improvement of iron intake alone has not been sufficient to mitigate IDA. Emerging critical risk factors for IDA include a composition of cultural diets, infections, genetics, inflammatory conditions, metabolic diseases, dysbiosis, and socioeconomic parameters. In this review, we discuss numerous IDA mitigation programs in India and their limitations. The new multifactorial mechanism of IDA pathogenesis opens perspectives for the improvement of mitigation programs and relief of IDA in India and worldwide.

Coverage of antenatal iron-folic acid and calcium distribution during pregnancy and their contextual determinants in the northeastern region of India

Iron-folic acid (IFA) and calcium supplementation are nutritional interventions recommended prophylactically (against maternal anemia and preeclampsia, respectively) to all antenatal mothers in India under basic antenatal care (ANC) services. Using Health Management Information System data (reporting period: 2018–19 to 2020–21), we mapped the coverage of antenatal IFA and calcium distribution across the remote northeastern region of India relative to the number of pregnant women (PW) who registered for ANC, disaggregated by states and districts. Variations in coverage were also investigated by subgroups based on contextual attributes, viz., physiography (hilly/ plateau/ plain), socioeconomic development (“aspirational”/ “non-aspirational”) and proportion of early ANC visits (low/ medium/ high). Full course of antenatal IFA and calcium supplements were received by 79.36 (95% CI: 79.31–79.40) and 61.26 (95% CI: 61.21–61.32) PW per 100 ANC registered women, respectively. There was widespread heterogeneity in outreach, with calcium coverage generally trailing behind IFA coverage. Among states, coverage of the two interventions (per 100 ANC registered women) was highest in Assam (97.06 and 78.11 PW, respectively) and lowest in Nagaland (24.87 and 16.77 PW, respectively). At the district-level, the two interventions failed to reach even 50 PW per 100 ANC registered women in 32 (out of 115) districts. The coverage tended to be inferior in districts that were hilly, “non-aspirational” and had low proportion of early ANC visits. The granular information provided by our findings will facilitate monitoring, root cause analyses, microplanning, informed resource allocation and tailoring of locally appropriate solutions to achieve targeted coverage improvements.

Dietary diversity as a sustainable approach towards micronutrient deficiencies in India

The silent epidemic of micronutrient deficiencies (MNDs) continues to be a major public health challenge in the developing world, including India. The prevalence of iron, iodine, zinc, vitamin A and folate deficiencies is alarmingly high worldwide. India is additionally facing a high prevalence of vitamin D and B12 deficiencies. To combat the hidden epidemic of MNDs, various governments around the world have mostly relied on supplementation or fortification-based interventions. India launched salt iodization programme in 1962 and vitamin A and iron-folate supplementation programmes in 1970. Yet, even after decades of these programmes, MNDs are still widespread in the country. Due to slow progress in alleviating the burden of most MNDs, the Government of India aims to scale up fortification-based intervention programmes. However, there are safety and effectiveness concerns with such approaches. Hence, overdependence on supplementation and fortification alone may be counterproductive. Instead, food based dietary diversification approach can be the way forward. In this article, we list the common MNDs in India, evaluate major policy interventions, discuss concerns pertaining to fortification and suggest the need for a concurrent food-based approach, in particular dietary diversification, as a long-term and sustainable strategy to address population-based MNDs.

Eye screening can be used to perform anemia screening and treatment in adolescent girls using ToucHb

Purpose

Anemia is common in adolescent girls. Apprehension while drawing blood to estimate hemoglobin concentration is a barrier for confirming anemia. ToucHb, a noninvasive instrument that estimates the hemoglobin by taking an image of the exposed conjunctiva, was used during eye screening to help diagnose and treat anemia.

Methods

ToucHb was used during secondary school eye screening and during house-to-house eye screening to estimate the hemoglobin concentration in the body. Each of the girls was distributed a packet of 60 tablets of ferrous and folate and a tablet of albendazole. They were followed up after 3 months.

Results

Exactly 1511 municipal school girls aged 10-19 years (mean 12.9; standard deviation [SD] 1.64) were examined. Of them, 949 (62.8%) had hemoglobin of ≤9 mg%. Among those girls with hemoglobin ≤9 mg%, the mean (SD) during the initial and follow-up examinations was 6.1 (1.4) and 9.6 (1.03), respectively, by paired t-test (P < 0.001). Another 588 girls (average age 14.4 years, SD 1.2) had their eyes examined and hemoglobin estimated during a house-to-house eye screening. Of them, 116 (19.7%) had hemoglobin level of ≤9 mg%. Their pre-Hb was 7.9 (SD 1.05) on average and after 3 months, it was 9.6 (SD 1.02). Among those girls with hemoglobin ≤9 mg%, the mean (SD) during the initial and follow-up examinations was 6.2 (1.4) and 7.9 (1.1), respectively, by paired t-test (P < 0.001).

Conclusion

ToucHb was useful to diagnose anemia while doing eye screening and to ensure its treatment. Anemia diagnosis and management would enhance the health of adolescent girls.

Coverage of Iron and Folic Acid Supplementation in India: Progress Under the Anemia Mukt Bharat Strategy 2017-2020

High prevalence of anemia is a severe public health problem in India. In 2018, India launched the Anemia Mukt Bharat (AMB) strategy that focuses on six beneficiary groups for coverage, six institutional mechanisms for health system strengthening and six programmatic interventions to accelerate reductions in anemia prevalence. This paper uses the Health Management Information System (HMIS) data (2017-18 to 2019-20) to examine gains in IFA coverage across Indian states. A coverage based AMB index is computed to review performance across states. After the launch of AMB strategy, the IFA supplementation coverage between 2017-18 and 2019-20 has increased for all beneficiary groups (pregnant women from 78% to 90%; lactating mothers from 34% to 49%; school going adolescent girls (boys) from 23% to 40% (21% to 42%); out-of-school adolescent girls from 6% to 23%; children 5-9 years from 8% to 3%; and, children 6-59 months from 7% to 15%). Coverage was relatively low for target groups being served through a multi-departmental convergence mechanism (health and other departments such as education department for schools or women and child development department for anganwadi centres) than compared to those served by health department alone. However, no major gender disparities are noted in the coverage of IFA supplementation among school-going girls and boys. Bulk of the variations in coverage is attributable to state-specific differences. Training and sensitization workshops for state and district officials are found to be associated with increased coverage across beneficiary groups. The paper argues that despite following international best practices in the field it is important to harness synergy in program implementation across line departments to eliminate coverage inefficiencies.

Maternal iron-and-folic-acid supplementation and its association with low-birth weight and neonatal mortality in India

OBJECTIVE

The 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.

DESIGN

The 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.

SETTING

NFHS-4 covered 640 districts from thirty-seven states and union territories of India.

PARTICIPANTS

A total of 120 374 and 143 675 index children aged 0-59 months were included to analyse LBW and neonatal mortality, respectively.

RESULTS

Overall, 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.

CONCLUSIONS

While ≥ 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.

Iron Fortification through Universal Distribution of Double-Fortified Salt Can Increase Wages and Be Cost-Effective: An Ex-Ante Modeling Study in India

BACKGROUND

The alleviation of iron deficiency through iron supplementation has not effectively reduced anemia in India, mainly due to low compliance. Food fortification with iron is considered a viable alternative, and the provision of double-fortified salt (DFS; with iron and iodine) has been mandated in public health programs. Limited evidence exists on its benefit-cost ratio.

OBJECTIVE

In this study we sought to estimate the economic benefit in terms of increased wages in relation to introduction of DFS in reduction of anemia and the cost of doing so.

METHODS

The economic benefit of introducing DFS in India was derived using a series of mathematical, statistical, and econometric models using data from national surveys capturing earnings and dietary iron intake of the population. Anemia status was predicted from data on dietary intake, sanitation, and for women, menstrual losses. The impact of iron deficiency anemia (IDA) on wages was estimated using a Heckman Selection model and 2-stage least squares procedure. Benefit of DFS was estimated through increased wages attributed to anemia reduction compared with its cost.

RESULTS

Men and women with IDA had lower wages (by 25.9%, 95% CI: 11.3, 38.1; and by 3.9%, 95% CI: 0.0, 7.7, respectively) than those without IDA. Additional iron intake through DFS was predicted to reduce prevalence of IDA (from 10.6% to 0.7% in men and 23.8% to 20.9% in women). The economic benefit-cost ratio of introducing DFS at a national level was estimated to be 4.2:1.

CONCLUSIONS

Iron fortification delivered through DFS under a universal program can improve wages and be sufficiently cost-effective for its implementation at scale in India.

Anemia Among Children Under 5 Years in India: A District-Level Spatial Analysis Using NFHS-5 Data

The 2015/2016 National Family Health Survey (NFHS-4) revealed that the prevalence of anemia among children under 5 years is 58% in India. Lack of nutritional supplementation and lack of health care facilities are found to be important influential factors of anemia among children. We aimed to examine district-level spatial heterogeneity and clustering of associated factors with childhood anemia in India. Geographically weighted regression was applied on the NFHS-5 data for 335 districts. Factors such as prevalence of nutritional supplementation in children and mothers, birth order, antenatal care, diarrhea in children, and stunting were found to be significantly associated. Spatial scan statistics technique identified 3 significant local spatial clusters of anemia. This study provides findings based on the latest available data which can further assist in the design and execution of tailor-made policies.

Validation of Global Diet Quality Score Among Nonpregnant Women of Reproductive Age in India: Findings from the Andhra Pradesh Children and Parents Study (APCAPS) and the Indian Migration Study (IMS)

BACKGROUND

In India, there is a need to monitor population-level trends in changes in diet quality in relation to both undernutrition and noncommunicable diseases.

OBJECTIVES

We conducted a study to validate a novel diet quality score in southern India.

METHODS

We included data from 3041 nonpregnant women of reproductive age (15-49 years) from 2 studies in India. Diet was assessed using a validated food frequency questionnaire (FFQ). The Global Diet Quality Score (GDQS) was calculated from 25 food groups (16 healthy; 9 unhealthy), with points for each group based on the frequency and quantity of items consumed in each group. We used Spearman correlations to examine correlations between the GDQS and several nutrient intakes of concern. We examined associations between the GDQS [overall, healthy (GDQS+), and unhealthy (GDQS-) submetrics] and overall nutrient adequacy, micro- and macronutrients, body mass index (BMI), midupper arm circumference, hemoglobin, blood pressure, high density lipoprotein (HDL), and total cholesterol (TC).

RESULTS

The mean GDQS was 23 points (SD, 3.6; maximum, 46.5). In energy-adjusted models, positive associations were found between the overall GDQS and GDQS+ and intakes of calcium, fiber, folate, iron, monounsaturated fatty acid (MUFA), protein, polyunsaturated fatty acid (PUFA), saturated fatty acid (SFA), total fat, and zinc (ρ = 0.12-0.39; P < 0.001). Quintile analyses showed that the GDQS was associated with better nutrient adequacy. At the same time, the GDQS was associated with higher TC, lower HDL, and higher BMI. We found no associations between the GDQS and hypertension.

CONCLUSIONS

The GDQS was a useful tool for reflecting overall nutrient adequacy and some lipid measures. Future studies are needed to refine the GDQS for populations who consume large amounts of unhealthy foods, like refined grains, along with healthy foods included in the GDQS.

Association of iron supplementation and dietary diversity with nutritional status and learning outcomes among adolescents: Results from a longitudinal study in Uttar Pradesh and Bihar, India

BACKGROUND

Poor nutritional status and educational outcomes are associated with adverse health consequences throughout the life course.

OBJECTIVES

We examined the associations of sex, iron and folic acid (IFA) supplementation, deworming, and dietary diversity with nutritional status and learning outcomes among Indian adolescents.

METHODS

Data of 12 035 adolescents from two rounds (2015-16 and 2018-19) of the Understanding the Lives of Adolescents and Young Adults surveys in Uttar Pradesh and Bihar, India were used. Multivariate linear and logistic regression models were used to estimate the prospective relationships of explanatory variables in the first round of the survey with nutritional status (ie, hemoglobin, BMI- and height-for-age z-scores, and incidence of anemia, stunting, and underweight) and learning outcomes (ie, reading proficiency, math proficiency, and school dropout) in the second round of the survey. The multivariable models were adjusted for a range of confounders, clustering by the population sampling unit and sampling weights.

RESULTS

Girls had a lower hemoglobin (adjusted mean difference (aMD) = -2.07; 95% confidence interval (CI) = -2.20, -1.94; P < 0.001) and height-for-age z-score (aMD = -0.45; 95% CI = -0.53, -0.38; P < 0.001) and higher BMI-for-age z-score (aMD = 0.36; 95% CI = 0.27, 0.44; P < 0.001) compared to boys. Girls had poorer reading (adjusted odds ratio (aOR) = 0.81; 95% CI = 0.70, 0.95; P = 0.01) and math proficiency (adjusted odds ratio aOR = 0.36; 95% CI = 0.31, 0.42; P < 0.001), and increased risk of school dropout (aOR = 1.65; 95% CI = 1.40, 1.95; P < 0.001) than boys. Receiving IFA tablets was not significantly associated with hemoglobin levels of adolescents overall, however we noted a significant beneficial relationship among girls (aMD = 0.41; 95% CI = 0.00, 0.82) but not among boys (aMD = 0.02; 95% CI = -0.38, 0.43) (P for interaction = 0.09). Receiving IFA tablets was positively associated with reading proficiency (aOR = 1.47; 95% CI = 1.07, 2.01; P = 0.02), math proficiency (aOR = 1.51; 95% CI = 1.16, 1.98; P < 0.001) and a reduced risk of school dropout (aOR = 0.72; 95% CI = 0.54, 0.96; P = 0.03). Deworming was not associated with nutritional status and learning outcomes. Diverse dietary intake was positively associated with hemoglobin, height-for-age z-score and math proficiency, and a reduced risk of school dropout in adolescents.

CONCLUSION

Integrated nutritional and health interventions and strengthening the existing nutrition supplementation program are critical to address adolescents' nutritional needs and improve educational outcomes.

Artificial Intelligence for solid tumor diagnosis in digital pathology

Tumor diagnosis relies on the visual examination of histological slides by pathologists through a microscope eyepiece. Digital pathology, the digitalization of histological slides at high magnification with slides scanners, has raised the opportunity to extract quantitative information thanks to image analysis. In the last decade, medical image analysis has made exceptional progress due to the development of artificial intelligence (AI) algorithms. AI has been successfully used in the field of medical imaging and more recently in digital pathology. The feasibility and usefulness of AI assisted pathology tasks have been demonstrated in the very last years and we can expect those developments to be applied on routine histopathology in the future. In this review, we will describe and illustrate this technique and present the most recent applications in the field of tumor histopathology.

Anaemia status of preconception young married women in India

The early detection of anaemia is important for its subsequent control and incidence among women of childbearing age. This study aimed to assess the anaemia status of preconception young married women in India using National Family Health Survey-4 data collected in 2015-16. A total 65,238 sample preconception young married women were analysed using univariate, bivariate and multivariate techniques. A majority belonged to the Hindu religion (81.7%), lived in rural areas (64.5%) and had secondary level education (51.8%), and 41.7% had not yet given birth. The percentage suffering from anaemia was 51.3%. The prevalence of anaemia was higher among younger women (55.3%), those from Scheduled Tribes (59.0%), those living in rural areas (52.8%), the non-educated (55.9%), those in the poorest wealth quintile (56.9%), those from the East region (57.0%) and those with a low body mass index (BMI) (58.4%). The adjusted odds ratios indicated that, after controlling for significant background factors, Hindu, Scheduled Tribe, Scheduled Caste, East region, already having a child, too thin for their height and poorer and poorest wealth quintiles had higher odds of suffering from anaemia compared with the reference groups. The odds of suffering from anaemia decreased with age and education. The study showed a high burden of anaemia and associated risk factors among preconception young married women in India. The finding will inform decision-makers when planning interventions to decrease anaemia among women of childbearing age in India.

Hyperhomocysteinemia and low vitamin B12 are associated with the risk of early pregnancy loss: A clinical study and meta-analyses

One-carbon metabolism is crucial for the maintenance of healthy pregnancy and alterations in this pathway have been associated with various pregnancy-related complications. Therefore, the present study was conducted to test the hypothesis that the altered folic acid, vitamin B12 and homocysteine levels are associated with the risk of early pregnancy loss (EPL). Plasma folic acid, vitamin B12 and homocysteine levels were analyzed in 83 females with EPL and 70 healthy pregnant females in their first trimester. Further, meta-analyses of folic acid, vitamin B12 and homocysteine were also performed involving various eligible studies. Results from our case-control study and meta-analysis showed that folic acid deficiency is not associated with the risk of EPL. On the other hand, low vitamin B12 and hyperhomocysteinemia were individually found to be significant risk factors for EPL in the present study (P < .01, P < .05, respectively) and meta-analysis as well (P < .001, P < .05, respectively). Vitamin B12 deficiency in combination with hyperhomocysteinemia was a more serious risk factor for EPL (Odds Ratio = 4.98, P = 0.002). Therefore, we conclude that vitamin B12 deficiency and elevated homocysteine levels are independent risk factors for EPL, and of higher risk when combined. The assessment of vitamin B12 and homocysteine levels may serve as a good screening marker for EPL risk.

Maternal Vitamin B12 Status During Pregnancy and Its Association With Outcomes of Pregnancy and Health of the Offspring: A Systematic Review and Implications for Policy in India

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.

Receipt of Weekly Iron Supplementation among Indian Children, 2005-2016

BACKGROUND

In response to India's unacceptably high burden of anemia among children aged 6-59 mo, the central government introduced the National Iron Plus Initiative program which recommends an intervention of iron supplementation to mitigate anemia, especially iron deficiency anemia.

OBJECTIVE

The objective of this study was to examine the trend (between 2005-2006 and 2015-2016) in receiving weekly iron supplementation (WIS) among children aged 6-59 mo, and factors associated with receiving WIS during 2015-2016.

METHODS

Two waves of the nationally representative cross-sectional National Family Health Survey (NFHS) data collected during 2005-2006 (NFHS-3) and 2015-2016 (NFHS-4) were used. The trend was measured using both rounds of datasets, whereas factors associated with WIS receipt were assessed from NFHS-4. The trend was assessed using a sample of 35,650 children from NFHS-3 and 202,227 children from NFHS-4. After exclusion of 8978 cases, a total of 199,110 children were included to analyze the factors associated with receiving WIS. Using appropriate sample weighting, unadjusted and adjusted (multivariate) logistic regression analyses were deployed. Application of the chi-squared test and checking for multicollinearity were also part of the analysis. The possibility of sample selection bias was tested.

RESULTS

An increase of WIS receipt (from 4.6% in 2005-2006 to 26% in 2015-2016) was observed. Older children, children living in rural areas, children belonging to Scheduled Tribes, children of mothers with secondary education or higher, and children whose mothers had some mass media exposure had higher odds of receiving WIS. Children of fifth or higher birth order, children who were followers of Islam and Christianity, children from the richest economic group, noninstitutional birth of children, and children from high-focus group states were negatively associated with WIS receipt.

CONCLUSIONS

Despite improvement (between 2005-2006 and 2015-2016) in receiving WIS, coverage remains unacceptably low (in absolute terms). The suboptimum performance of WIS intervention demands further investigation.

The Association Between Ambient PM2.5 Exposure and Anemia Outcomes Among Children Under Five Years of Age in India

Anemia is highly prevalent in India, especially in children. Exposure to ambient fine particulate matter (PM2.5) is a potential risk factor for anemia via. systemic inflammation. Using health data from the National Family and Health Survey 2015-2016, we examined the association between ambient PM2.5 exposure and anemia in children under five across India through district-level ecological and individual-level analyses.

METHODS

The ecological analysis assessed average hemoglobin levels and anemia prevalence (hemoglobin < 11 g/dL considered anemic) by district using multiple linear regression models. The individual-level analysis assessed average individual hemoglobin level and anemia status (yes/no) using generalized linear mixed models to account for clustering by district. Ambient PM2.5 exposure data were derived from the Multiangle Imaging SpectroRadiometer (MISR) level 2 aerosol optical depth (AOD) data and averaged from birth date to date of interview.

RESULTS

The district-level ecological analysis found that, for every 10 μg m-3 increase in ambient PM2.5 exposure, average anemia prevalence increased by 1.90% (95% CI = 1.43, 2.36) and average hemoglobin decreased by 0.07 g/dL (95% CI = 0.09, 0.05). At the individual level, for every 10 μg m-3 increase in ambient PM2.5 exposure, average hemoglobin decreased by 0.14 g/dL (95% CI = 0.12, 0.16). The odds ratio associated with a 10-μg m-3 increase in ambient PM2.5 exposure was 1.09 (95% CI = 1.06, 1.11). There was evidence of effect modification by wealth index, maternal anemia status, and child BMI.

CONCLUSION

Our results suggest that ambient PM2.5 exposure could be linked to anemia in Indian children, although additional research on the underlying biologic mechanisms is needed. Future studies on this association should specifically consider interactions with dietary iron deficiency, maternal anemia status, and child BMI.Keywords: Anemia; Children; Ambient PM2.5 exposure; India; Association.

Micronutrient-fortified rice improves haemoglobin, anaemia prevalence and cognitive performance among schoolchildren in Gujarat, India: a case-control study

Anaemia is a public health problem in India. A case-control, quasi-experimental study was conducted to evaluate the effect of a multiple micronutrient fortified rice intervention among school children (6-12 years) through the midday meal programme in Gujarat, India, over 8 months. The fortified rice provided approximately 10% Recommended Dietary Allowance of iron; 25-33% of vitamin A, thiamine, niacin and vitamin B6; and 100% of folic acid and vitamin B12. Outcomes of interest included haemoglobin concentration, anaemia prevalence, and cognitive performance. Cognitive performance was evaluated using J-PAL-validated Pratham reading and mathematics testing tools. 973 children completed the study (cases n = 484; controls n = 489). The intervention significantly increased mean haemoglobin by 0.4 g/dL (p = 0.001), reduced anaemia prevalence by 10% (p < 0.00001), and improved average cognitive scores by 11.3 points (p < 0.001). Rice fortification can help address anaemia in settings where rice is a staple food.
