Effect of a Community Health Worker-Delivered Parental Education and Counseling Intervention on Anemia Cure Rates in Rural Indian Children: A Pragmatic Cluster Randomized Clinical Trial

Interventions to improve vitamin and mineral inadequacies among children in India: a scoping review

INTRODUCTION

Vitamin and mineral deficiencies are commonly seen in children, and they affect the physical, mental and cognitive development of a child.

OBJECTIVE

This study aimed to map interventions to improve vitamin and mineral inadequacies among children in India.

METHODS

A review was conducted using the PRISMA extension for scoping reviews (PRISMA-ScR) 2018 checklist. Based on the PICO framework, further steps were followed in conducting the review. Studies conducted on children and adolescents (ranging in age from 6 months to 19 years) in India were considered. A search was carried out in PubMed, CINAHL, ProQuest, Cochrane Library, Scopus and Web of Science. Interventions that focused on improving vitamin and mineral inadequacies were collated. Studies published in the English language between 1 January 2012, and 30 September 2023, were included. The data from the included studies were reported narratively.

RESULTS

The search yielded 1566 records through the databases. Finally, 18 studies were found to be eligible to be considered in this review. For improving vitamin and mineral deficiencies, different types of supplements like iron, vitamins A, C and D in different amounts; nutritional supplements like zinc-rich foods, whole-wheat recipes, milk, lipid-based vitamin B12 supplements, ragi, porridge and iron-fortified whole-wheat drinks; or nutritional counselling worked better in children.

CONCLUSION

Vitamin and mineral supplementation for children reduces anaemia among children. Policymakers need to develop a strategy to increase awareness among parents, AWWs, caregivers and schoolteachers to reduce further complications.

Systematic review on supplementation, fortification, and food-based interventions for preventing iron deficiency anemia in low- and middle-income countries

BACKGROUND AND OBJECTIVES

Prioritizing key preventive and therapeutic interventions is one of the actions to accelerate the reduction of anemia. This study aimed to examine interventions designed to prevent anemia.

METHODS AND STUDY DESIGN

A systematic search was conducted in PubMed, Web of Science, Scopus, and Cochrane Library. Analysis of publication bias was done using The Joanna-Briggs Institute critical appraisal tool. Data collected from articles included author, year of publication, setting and location of the study, study type, participant of the study, intervention and control given, main outcome, main findings, and risk of bias.

RESULTS

Three nutrition-specific interventions aimed at preventing iron deficiency anemia in low- and middle-income countries used various types and dosages of iron. While most studies showed success, some indicated a worsening trend in anemia, even with standard dosages and the same form of iron. Determining effective interventions requires consideration of factors such as other micronutrient composition, compliance rate, availability of educational intervention, and dietary backgrounds in those countries.

CONCLUSIONS

Supplementation, fortification, and food-based interventions generally lead to higher hemoglobin levels and a lower prevalence of anemia. However, it is important to consider several factors before deciding on an approach.

Evaluating the Impact of an Iron Supplementation Program for Combating Anemia in School-Age and Adolescent Females by a Grassroots Organization in India

BACKGROUND AND OBJECTIVE

Iron deficiency anemia (IDA) is a prominent cause of anemia adversely affecting the physical, mental, and social well-being of an individual. It is a major health concern and has impacted more than two billion people worldwide. It is necessary to implement programs to increase compliance rates for iron and folic acid (IFA) supplementation and educate individuals about anemia. In this study, we evaluate the impact of a non-profit organization's IFA supplementation program for school-age and adolescent females to combat anemia.

METHODOLOGY

This study was conducted via a grassroots organization that used a peer network to integrate with the existing national anemia campaign in school-age and adolescent females. This single-arm preintervention and postintervention study conducted over four months from June to September 2023 evaluated the effect of a one-time anti-helminthic treatment and weekly IFA supplementation (45 mg elemental iron and 0.4 mg folic acid per tablet for seven to nine-year-old females; 60 mg elemental iron and 0.5 mg folic acid per tablet for 10 to 19-year-old females) for 90 days. Hemoglobin levels at baseline and post-IFA supplementation were assessed using point-of-care direct reading hemoglobinometers. The pre- and post-test hemoglobin values were compared by a paired t-test.

RESULTS

A total of 160 females visiting the foundation were approached, out of which 146 agreed to participate in the study. The baseline hemoglobin levels among 146 females were 10.9 ± 1.7 g/dL, and 103 (70.5%) of them were observed to have anemia. Due to a loss of follow-up, 99 participants were evaluated for pre- and post-IFA supplementation hemoglobin levels. Among 99 females, anemia was observed in 68.7% at baseline. The baseline hemoglobin level of 11.1 ± 1.7 g/dL significantly raised to 11.7 ± 1.4 g/dL after IFA supplementation (p<0.001). After IFA supplementation, the baseline distribution of participants with normal hemoglobin rose to 47.5% (post-test) from 31.3% (pre-test), showing a difference of 16.2%. The normal hemoglobin level distribution across the age groups after the weekly IFA supplementation program improved by 17.2% in participants aged seven to 10 years (from 31.4% to 48.6%), 17.7% in 11 to 14 years (from 29.45% to 47.1%), and 7.7% in those aged 15 to 19 years (from 38.5% to 46.2%).

CONCLUSION

Grassroots organizations can be pivotal in enhancing the efficacy of IFA supplementation programs, particularly in combating anemia among children. Behavior change communication and peer networks of such organizations can be integrated into existing programs to significantly contribute to improving the compliance rate of IFA supplementation programs.

Systematic review and meta-analysis of interventions to promote medication adherence among children, adolescents, and young adults with medical conditions

OBJECTIVE

This meta-analysis examined the efficacy of adherence-promotion interventions for children, adolescents, and young adults prescribed a medication for > 90 days as part of a treatment regimen for a medical condition.

METHODS

A systematic literature review was conducted to identify randomized controlled trials of adherence-promotion interventions published between 2013 and 2023 and including children, adolescents, and/or young adults with a medical condition. A total of 38 articles representing 39 trials met inclusion criteria. A narrative synthesis was conducted to summarize included trials and a random-effects model was used to compute an overall intervention effect. Effect sizes by adherence outcome assessment methodology, participant age, and technology use were also computed.

RESULTS

Pediatric adherence-promotion interventions demonstrate a medium effect with those randomized to an intervention displaying greater improvements in medication adherence than those randomized to a comparator condition (SMD = 0.46, 95% CI: 0.31, 0.60, n = 37; 95% Prediction Interval: -0.32, 1.23).

CONCLUSIONS

Adherence interventions for children, adolescents, and young adults with medical conditions increase adherence.

Prevalence and Correlates of Anemia among Adolescents Living in Hodeida, Yemen

This study assesses the prevalence and correlates of anemia among adolescents living in the war-affected region of Hodeida in Yemen. A secondary objective was to examine the effect of a nutrition education intervention on hemoglobin levels among anemic adolescents. A cross-sectional study was conducted on a random sample of adolescents aged 15–19 years in Hodeida (n = 400). A questionnaire was administered to inquire about demographic, socioeconomic, lifestyle and clinical characteristics. Capillary blood was obtained, anthropometric characteristics were measured and stool samples were collected. As for the secondary objective, anemic adolescents were randomly assigned to an intervention group (nutrition education and iron supplementation) and a control group (iron supplements only). The prevalence of anemia was 37.8%. Female gender, khat chewing, excessive menstruation, and experiencing headaches, fatigue, or dizziness were independent predictors of anemia. In contrast, adolescents who attended private schools, and reported snack consumption or handwashing had a significantly lower risk of anemia. A sample of 116 adolescents participated in the intervention (3 months). Hemoglobin levels were significantly higher in the intervention group compared to the control. Our findings contribute to the identification of high-risk groups that should be targeted by context-specific interventions. The implemented multicomponent intervention may serve as a prototype for larger-scale preventive programs.

Global burden and inequality of iron deficiency: findings from the Global Burden of Disease datasets 1990-2017

BACKGROUND

Iron deficiency (ID) impairs patient physical activity, recognition and life quality, which is difficult to perceive but should not be underestimated. Worldwide efforts have been made to lower ID burden, however, whether it decreased equally in different regions and sexes is unclear. This study is to examine regional and sex inequalities in global ID from 1990 to 2017.

METHODS

We conducted a longitudinal, comparative burden-of-disease study. Disability-adjusted life-years (DALYs) of ID were obtained from Global Burden of Disease Report 2017. Human Development Index (HDI) data were obtained from Human Development Report 2017. Gini coefficient and the concentration index were calculated to assess the equities in global burden of ID.

RESULTS

A downward trend of global ID burden (from 569.3 (95% Uncertainty Interval [UI]: 387.8-815.6) to 403.0 (95% UI: 272.4-586.6), p < 0.001), age-adjusted DALYs per 100,000 population) but an uptrend of its inequalities (from 0.366 to 0.431, p < 0.001, Gini coefficients) was observed between 1990 and 2017. ID burden was heavier in women than that in men ([age-adjusted DALYs per 100,000 population from 742.2 to 514.3] vs [from 398.5 to 291.9]), but its inequalities were higher in men since 1990. The between-sex gap of ID burden was narrowed with higher HDI (β =  - 364.11, p < 0.001). East Asia & Pacific and South Asia regions made a big stride for ID control in both sexes over decades [age-adjusted DALYs per 100,000 population from 378.7 (95% UI: 255.8-551.7) in 1990 to 138.9 (95%UI: 91.8-206.5) in 2017], while a heavy burden among Sub-Saharan African men was persistent[age-adjusted DALYs per 100,000 population, 572.5 (95% UI: 385.3-815) in 1990 and 562.6 (95% UI: 367.9-833.3) in 2017].

CONCLUSIONS

Redistributing attention and resources to help countries with low HDI, especially take care of women with low socioeconomic status (SES) and men under high ID burden may help hold back the expanding ID inequality.

Effect of a maternal counselling intervention delivered by community health workers on child nutrition: secondary analysis of a cluster randomised controlled trial in India

Background

India suffers from a double burden of malnutrition and anaemia. The Karnataka anaemia project indicated that a counselling intervention delivered by community health workers improved anaemia cure rates.

Objective

To evaluate the effect of maternal counselling on nutritional aspects of anaemia prevention.

Methods

Secondary analysis of a cluster randomised controlled trial (55 simultaneously randomised villages using random number generator in Chamrajnagar district, Northern India). In the intervention group mothers of anaemic children received five monthly counselling sessions plus usual care (iron and folic acid supplements), while mothers of anaemic children in the control group received usual care alone. Daily intake of nutrients related to anaemia prevention, i.e. iron (mg) and vitamin C (mg), was estimated using the 24-h dietary recall method at baseline and 6 months follow-up. Linear and logistic mixed regression models were used to assess between-groups difference in changes in nutrients intake from baseline to end of follow-up. Data collectors and analysts were blinded to the group assignment.

Results

Participants were 534 (intervention n = 303; usual treatment n = 231) anaemic children, aged 1 to 5 years and their caregivers, of whom 521(intervention n = 299 from 28 villages; usual treatment n = 222 from 27 villages) were retained at 6 months follow-up and included in the analysis. This study provides inconclusive evidence of improvement in the intake of nutrients that prevent anaemia from baseline to follow-up among the intervention compared to the control group; increase in iron intake was 0.24 mg/day (95% CI -0.67; 1.15) and increase in vitamin C intake was 4.61 mg/day (95% CI -0.69, 9.91). Although encouraging, it is notable that the overall intake of nutrients that prevent anaemia remained well below the national recommended daily allowance.

Conclusion

This study provides inconclusive evidence of the effect of parental counselling on nutritional aspects of anaemia prevention. The results highlight the need to devise multi-component anaemia-prevention interventions that include facilitators of the availability of nutritious food and should be evaluated in studies that are adequately powered to detect nutritional changes.

Are Countries of the Eastern Mediterranean Region on Track towards Meeting the World Health Assembly Target for Anemia? A Review of Evidence

Anemia is a multifactorial condition, with a complex etiology that involves nutritional and non-nutritional factors. The misconception that iron deficiency is equivalent to anemia may mask the need to address other potential causative factors. This review paper aims to (1) assess the burden of anemia vs. iron deficiency anemia (IDA) amongst women of reproductive age (WRA), pregnant women (PW), and children under five years old (underfive children, U5C) in the Eastern Mediterranean region (EMR); (2) evaluate trends in anemia prevalence and whether countries are on track towards meeting the World Health Assembly (WHA) target for 2025; and (3) characterize anemia reduction efforts and provide a road map for future programs. A search of pertinent literature and databases was conducted. Anemia prevalence in the EMR ranged between 22.6% and 63% amongst PW, 27% and 69.6% amongst WRA, and 23.8% and 83.5% amongst U5C. Data showed that the EMR is not on course towards meeting the WHA target. The contribution of IDA to anemia was found to be less than half. Other potential contributors to anemia in the region were identified, including micronutrient deficiencies, parasitic infestations, and poor sanitation. A framework of action was proposed as a roadmap to meet the targets set by the WHA.

The reduction in anemia through normative innovations (RANI) project: study protocol for a cluster randomized controlled trial in Odisha, India

BACKGROUND

More than half of women in India are anemic. Anemia can result in fatigue, poor work productivity, higher risk of pre-term delivery, and maternal mortality. The Indian government has promoted the use of iron-folic acid supplements (IFA) for the prevention and treatment of anemia for the past five decades, but uptake remains low and anemia prevalence high. Current programs target individual-level barriers among pregnant women and adolescents, but a more comprehensive approach that targets multiple levels among all women of reproductive age is needed to increase uptake of IFA and iron-rich foods.

METHODS

The Reduction in Anemia through Normative Innovations (RANI) project is a norms-based intervention to reduce anemia among women of reproductive age. We will evaluate the intervention through a clustered randomized controlled trial in Odisha, India. We will collect data at three time points (baseline, midline, and end line). For the study, we selected 89 clusters of villages, which we randomized into treatment and control on a 1:1 basis. The treatment arm will receive the RANI project components while the control arm will receive usual care. Fifteen clusters (40-41 villages) were selected and 4000 women (2000 in each arm) living in the selected clusters will be randomly selected to take part in data collection. Women in both study arms will have their hemoglobin concentrations measured. They will also complete in-person surveys about their knowledge, attitudes, perceptions of iron folic acid supplements, and nutritional intake. We will also select a smaller cohort of 300 non-pregnant women (150 in each arm) from this cohort for additional physical activity and cognitive testing. We will conduct both within- and between-group comparisons (treatment and control) at baseline, midline and end line using t-tests. We will also conduct structural equation modeling to examine how much each factor accounts for IFA use and hemoglobin levels.

DISCUSSION

This RCT will enable us to examine whether a social norms-based intervention can increase uptake of iron folic acid supplements and iron rich foods to reduce anemia.
