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

Interpersonal Communication Strategies to Increase Iron-Folic Acid Supplement Consumption: Reduction in Anemia Through Normative Innovations (RANI) Project

More than half of women of reproductive age in India are anemic. This study investigates the role of interpersonal communication in increasing the consumption of iron-folic acid supplements. Interventions that increase interpersonal communication may influence and empower individuals and the larger community in promoting behavior change. This investigation uses data from a cluster randomized intervention to understand the pathways by which interpersonal communication mediates the consumption of iron-folic acid supplements. Longitudinal data from control and intervention arms in rural Odisha, India, were collected at baseline (N = 3,691) and 20 months later at end-line (N = 3,394). Structural equation models highlighted the positive role of interpersonal communication in mediating iron-folic acid supplement use. This study illustrates that even during social distancing due to COVID-19, strategic interpersonal communication can improve iron-folic acid supplement use. Our results elucidate two key interpersonal communication pathways at play, namely the ritualistic and instrumental pathways in improving health behavior change in the community.

How Do Social and Behavioral Change Interventions Respond to Social Norms to Improve Women's Diets in Low- and Middle-Income Countries? A Scoping Review

Healthy dietary practices are highly influenced by social norms, the widely-held expectations about the behaviors that are appropriate or typical within a given group. However, many nutrition programs designed to reduce women's undernutrition in low- and middle-income countries do not address the influence of social and gender norms in their interventions, and therefore, there is limited information about how norms-responsive interventions have been designed and implemented. The objective of this scoping review was to identify and describe social and behavioral change interventions designed to improve women's dietary practices and nutritional intake that integrate the influence of social and gender norms. We systematically searched 4 databases (Scopus, Web of Science, PubMed, and CINAHL) for peer-reviewed articles describing design, implementation, and/or assessment of nutrition interventions in low- or middle-income countries. Results are reported following Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines. Our review identified 27 articles from 25 projects or research studies that addressed social or gender norms related to women's dietary practices. The majority focused on the pregnancy and lactation periods, and a few aimed to reach all women of reproductive age. Interventions most often endeavored to shift norms through multiple activities, channels, and platforms, aiming to reach not only the primary participants but also influencers and reference groups. Intervention approaches ranged from home visits and support groups to engage influential family members to community-level outreach with opinion leaders such as religious leaders, health care workers, and peer change agents. Most interventions were delivered through the health sector or were community-based, with some nutrition-sensitive agriculture interventions. There is increasing, although still limited, integration of social and gender norms perspectives in the design, implementation, and assessment of interventions to improve women's diets. This comprehensive review summarizes influential norms and intervention approaches, an important step toward enhancing the effectiveness of social and behavioral change interventions by addressing nutrition-relevant norms. This study was registered at Open Science Framework as JSBF7.

Study protocol for an individually randomized control trial for India's first roleplay-based mobile game for reproductive health for adolescent girls

BACKGROUND

Go Nisha Go™ (GNG), is a mobile game combining behavioural science, human-centric design, game-based learning, and interactive storytelling. The model uses a direct-to-consumer (DTC) approach to deliver information, products, services, interactive learning, and agency-building experiences directly to girls. The game's five episodes focus on issues of menstrual health management, fertility awareness, consent, contraception, and negotiation for delay of marriage and career. The game's effectiveness on indicators linked to these issues will be measured using an encouragement design in a randomized controlled trial (RCT).

METHODS

A two-arm RCT will be conducted in three cities in India: Patna, Jaipur, and Delhi-NCR. The first arm is the treatment (encouragement) arm (n = 975) where the participants will be encouraged to download and play the game, and the second arm (n = 975) where the participants will not receive any nudges/encouragement to play the game. They may or may not have access to the game. After the baseline recruitment, participants will be randomly assigned to these two arms across the three locations. Participants of the treatment/encouragement arm will receive continuous support as part of the encouragement design to adopt, install the game from the Google Play Store at no cost, and play all levels on their Android devices. The encouragement activity will continue for ten weeks, during which participants will receive creative messages via weekly phone calls and WhatsApp messages. We will conduct the follow-up survey with all the participants (n = 1950) from the baseline survey after ten weeks of exposure. We will conduct 60 in-depth qualitative interviews (20 at each location) with a sub-sample of the participants from the encouragement arm to augment the quantitative surveys.

DISCUSSION

Following pre-testing of survey tools for feasibility of methodologies, we will recruit participants, randomize, collect baseline data, execute the encouragement design, and conduct the follow-up survey with eligible adolescents as written in the study protocol. Our study will add insights for the implementation of an encouragement design in RCTs with adolescent girls in the spectrum of game-based learning on sexual and reproductive health in India. Our study will provide evidence to support the outcome evaluation of the digital mobile game app, GNG. To our knowledge this is the first ever outcome evaluation study for a game-based application, and this study is expected to facilitate scalability of a direct-to-consumer approach to improve adolescent sexual and reproductive health outcomes in India.

Exploring Perceptions and Needs of Mobile Health Interventions for Nutrition, Anemia, and Preeclampsia among Pregnant Women in Underprivileged Indian Communities: A Cross-Sectional Survey

According to the National Family Health Survey of 2021, about 57% of women aged 15-49 in India currently suffer from anemia, marking a significant increase from the 53% recorded in 2016. Similarly, a study conducted in southern India reported a 32.60% prevalence of preeclampsia. Several community-based initiatives have been launched in India to address these public health challenges. However, these interventions have yet to achieve the desired results. Could the challenges faced by traditional healthcare interventions be overcome through a technological leap? This study assesses pregnant mothers' perceptions regarding mobile health interventions for managing anemia and preeclampsia. Additionally, the study captures their health awareness and knowledge. We conducted a survey with 131 pregnant mothers in three underserved villages in Jharkhand, India. Statistical analysis was conducted using the SEMinR package in R (Version 2023.06.0), utilizing the non-parametric partial least squares-structural equation modeling. We found that every household had at least one smartphone, with the respondents being the primary users. The main uses of smartphones were for calling, messaging, and social media. A total of 61% of respondents showed interest in a nutrition and pregnancy app, while 23.66% were uncertain. Regarding nutritional knowledge during pregnancy, 68.7% reported having some knowledge, but only 11.45% claimed comprehensive knowledge. There was a considerable knowledge gap regarding the critical nutrients needed during pregnancy and the foods recommended for a healthy pregnancy diet. Awareness of pregnancy-related conditions such as anemia and preeclampsia was low, with most respondents unsure of these conditions' primary causes, impacts, and symptoms. This study serves as a critical step towards leveraging technology to enhance public health outcomes in low-resource settings. With the accessibility of mobile devices and an apparent willingness to utilize mHealth apps, compounded by the pressing need for improved maternal health, the impetus for action is indisputable. It is incumbent upon us to seize this opportunity, ensuring that the potential of technology is fully realized and not squandered, thus circumventing the risk of a burgeoning digital divide.

Monitor to innovate with feedback loops: process evaluation protocol for an anemia prevention intervention

Background: Digital process monitoring and evaluation tools designed to capture near-to-real-time intervention data paired with feedback loops have the potential to innovate intervention delivery.

Objective: To describe how a multilevel social norms field trial (RANI) is using feedback loops to enhance intervention delivery.

Methods: We use a mixed-methods process evaluation design to monitor the Reduction of Anemia through Normative Innovations (RANI) project; a three-year randomized control trial which aims to lower rates of anemia among women in Odisha, India. Surveys and structured observation monitor fidelity to implementation and acceptability of implementation activities among study participants. Quantitative data evaluates implementation dose, coverage, exposure, and reach of intervention activities, and qualitative data will delve more deeply into reasons for high or low functioning. Iron folic acid supplement supply and demand are also monitored for stock-outs. Data collected from 130 intervention villages is processed, visualized, and triangulated in near to real-time via Real-time Monitoring for Knowledge Generation (RPM4K), a locally developed software application. Data visualization products facilitate the examination of monitoring data to mitigate bottlenecks and identify and implement tweaks to our intervention delivery strategy on an ongoing basis.

Discussion: Feedback loops facilitate timely course corrections. Feedback loops can also engender a shared understanding of ground realities for a geographically dispersed and culturally diverse team. Leveraging feedback loops, we identify opportunities to provide on-going supportive supervision for our community facilitators promoting joint problem-solving, and communication. Monthly media and hemoglobin level demonstration strategies are informed by participant engagement and acceptability. Stock-outs of iron folic acid tablets activate contingency plans to mobilize local stakeholders and advocate for timely resolutions. Unintended effects are monitored based on ongoing feedback from community facilitators.

Conclusions: Documenting our processes can inform the future implementation or scale up of similar projects embracing feedback loops to iterate and innovate their intervention delivery.

The G-NORM Scale: Development and Validation of a Theory-Based Gender Norms Scale

Gender norms are increasingly recognized as important modifiers of health. Despite growing awareness of how gender norms affect health behavior, current gender norms scales are often missing two important theoretical components: differentiating between descriptive and injunctive norms and adding a referent group. We used a mixed-methods approach to develop and validate a novel gender norms scale that includes both theoretical components. Based on qualitative data, the theory of normative social behavior, and the theory of gender and power, we generated a pool of 28 items. We included the items in a baseline questionnaire among 3,110 women in Odisha, India as part of a cluster randomized controlled trial. We then ran exploratory factor analysis which resulted in 18 items. Using a second wave of data with the same sample, we evaluated psychometric properties using confirmatory factor analysis and structural equation modeling. The analysis resulted in two subscales with nine items each, “descriptive gender norms” and “injunctive gender norms.” Both subscales represent high internal validity with Cronbach’s alpha values of 0.81 and 0.84 and the combined scale has an alpha of 0.87. The G-NORM, gender norms scale, improves on existing measures by providing distinct descriptive and injunctive norms subscales and moving beyond individual attitudes by assessing women’s perceptions of community-level gender norms.

How does a social norms-based intervention affect behaviour change? Interim findings from a cluster randomised controlled trial in Odisha, India

BACKGROUND

Behaviour change interventions targeting social norms are burgeoning, but researchers have little guidance on what they look like, and which components affect behaviour change. The Reduction in Anaemia through Normative Innovations (RANI) project designed an intervention to increase iron folic acid (IFA) consumption in Odisha, India.

OBJECTIVE

This paper examines the effect of the intervention at midline to understand which components of the RANI intervention affect uptake.

METHODS

Using a cluster randomised controlled design, we collected baseline data and midline data 6 months later from women of reproductive age in the control and treatment arms (n=3800) in Angul, Odisha, India. Using nested models, we analysed data from three different intervention components, monthly community-based testing for anaemia, participatory group education sessions, and videos, to determine the extent to which exposure to each of these components accounted for the overall intervention effect on haemoglobin and self-reported IFA use.

RESULTS

Overall, residing in a treatment as opposed to control village had little effect on midline haemoglobin, but increased the odds of taking supplements by 17 times. Exposure to each of the intervention components had a dose-response relationship with self-reported IFA use. These components, separately and together, accounted for most of the overall effect of treatment assignment on IFA use.

CONCLUSIONS

All intervention components increased iron supplement use to differing degrees of magnitude. It appears that a social norms-based approach can result in improving IFA uptake, though improvements in haemoglobin counts were not yet discernible.

The development and feasibility of a group-based household-level intervention to improve preconception nutrition in Nawalparasi district of Nepal

Background

In a setting such as Nepal with malnutrition and persistent poor maternal and infant health outcomes, developing interventions to improve the nutrition of preconception and pregnant women is essential.

Objective

The objectives of this paper are to describe the full design process of an intervention for newly married women, their husbands, and mothers-in-law to improve maternal nutrition and gender norms, and findings from the feasibility and acceptability pilot.

Methods

In this paper we describe the three phases of the design of an intervention in rural Nepal. We first conducted a mixed methods formative phase which included in depth interviews with newly married women, their husbands and mothers-in-law (N=60) and a longitudinal study for 18 months with 200 newly married women. We then designed of a household level, group, intervention, in close partnership with community members. Finally, we conducted a pilot intervention with 90 participants and collected both pre/post survey data and in-depth qualitative interviews with a subset (N= 30). All participants from all phases of the study lived in Nawalparasi district of Nepal. Qualitative data was analyzed using a thematic analysis, with inductive and deductive themes and quantitative data was analyzed using descriptive statistics.

Results

Our formative work highlighted lack of awareness about nutrition, and how women eating last, limited mobility, household and community inequitable gender norms and poor household-level communication contributed to low quality diets. Thus we designed Sumadhur, an intervention that brought groups of households (newly married wife, husband, and mother-in-law) together weekly for four months to strengthen relationships and gain knowledge through interactive content. We found Sumadhur to be highly feasible and acceptable by all respondents, with most (83%) attending 80% of sessions or more and 99% reporting that they would like it to continue. Pre/post surveys showed a decrease in the proportion of women eating last and increase in knowledge about nutrition in preconception and pregnancy. Qualitative interviews suggested that respondents felt it made large impacts on their lives, in terms of strengthening relationships and trust, understanding each other, and changing behaviors.

Conclusions

We show how a designing an intervention in close partnership with the target recipients and local stakeholders can lead to an intervention that is able to target complicated and culturally held practices and beliefs, positively benefit health and wellbeing, and that is very well received.

Improving iron folic acid consumption through interpersonal communication: Findings from the Reduction in Anemia through Normative Innovations (RANI) project

OBJECTIVE

More than half of Indian women of reproductive age are anemic. Regular iron folic acid uptake can prevent and treat anemia. This study investigated the effect of interpersonal communication on improving IFA use among women of reproductive age.

METHODS

The Reduction in Anemia through Normative Innovations (RANI) Project is a cluster randomized trial that collected longitudinal data from control (n = 1896) and intervention (n = 1898) communities in Odisha, India at Time 1 and six months later at Time 2. Structural equation models assessed the effect of the intervention on iron folic acid use via multiple interpersonal communication pathways.

RESULTS

Compared to the control arm, iron folic acid use significantly increased in the intervention arm. Both, general health interpersonal communication and anemia-specific interpersonal communication were augmented in the intervention communities. The impact of the intervention on iron folic acid use was mediated through anemia-specific interpersonal communication.

CONCLUSION

The RANI Project increased interpersonal communication among participants, resulting in increased iron folic acid use for anemia reduction.

PRACTICE IMPLICATIONS

Strategic use of targeted interpersonal communication to promote behavior change appears to be a viable strategy to increase iron folic acid use to reduce anemia.

mHealth for Anemia Reduction: Protocol for an Entertainment Education-Based Dual Intervention

Background

More than half of the women of reproductive age (aged 15-49 years) are anemic in India. The uptake of and adherence to iron folic acid (IFA) supplements remain low despite sustained efforts to increase their use. With India’s burgeoning digital environment, mobile phones offer a potential medium for increasing their uptake, especially when combined with interactive voice messages that deliver entertaining stories infused with norms-based educational messages.

Objective

This study aims to investigate whether a norms-based entertainment education mobile health intervention can increase self-efficacy for IFA adherence among women of reproductive age in Odisha, India.

Methods

Mobile reduction in anemia through normative innovations (mRANI) is a randomized 2-arm study that includes assessments before and after the intervention. All study participants will be recruited from the intervention arm of the parent reduction in anemia through normative innovations trial only. Although the usual practice is to randomize participants either to a treatment arm or a usual care control arm, we will assign the mRANI control group to another entertainment education–based treatment group that is designed to improve bystander intervention to reduce violence against women. Data collection for the mRANI study is embedded in the parent trial and will include baseline and end line assessments. The primary outcomes are self-efficacy for IFA adherence and violence against women–related bystander intervention. The inclusion criteria for the mRANI study are participation in the parent trial and phone ownership. Women (approximately n=400) who meet the mRANI inclusion criteria will be randomly assigned to the IFA arm or the bystander arm. Ordinary least squares regression with robust SEs will be conducted to assess between-group comparisons at the end line. A mediation analysis will be conducted to examine whether social norms and interactivity mediate the relationship between intervention exposure and primary outcomes in both arms. Real-time monitoring data will offer insights into intervention receptivity and audience engagement.

Results

Data collection for the mRANI study is integrated within the parent trial. Household surveys were conducted between February and March of 2021. Responses on the mRANI study’s primary and secondary outcomes were collected from 381 participants. The data analysis is expected to be completed by October 2021.

Conclusions

This study will provide evidence on whether a mobile health norms–based entertainment education intervention can increase self-efficacy for IFA adherence and violence against women–related bystander intervention.

Iron and folic acid consumption and changing social norms: cluster randomized field trial, Odisha, India

Objective

To assess whether improvements in social norms related to iron and folic acid consumption are associated with increased iron and folic acid consumption.

Methods

In a cluster randomized trial in Odisha, India, we implemented an intervention to improve descriptive norms (people’s perceptions about how many other people take iron and folic acid), injunctive norms (social pressures people feel to take iron and folic acid) and collective norms (actual levels of iron and folic acid consumption). We assessed changes in these norms and self-reported iron and folic acid consumption in control and intervention arms after 6 months (September 2019–February 2020). We collected data from control (n = 2048) and intervention (n = 2060) arms at baseline and follow-up (n = 1966 and n = 1987, respectively).

Findings

At follow-up, mean scores in self-reported iron and folic acid consumption in the control arm had decreased from 0.39 to 0.31 (21% decrease; not significant). In the intervention arm, mean scores increased from 0.39 to 1.62 (315% increase; P < 0.001). The difference between the two arms was statistically significant (P < 0.001). Each of the three norms also improved at significantly higher rates in the intervention than in the control arm (P < 0.001 for each norm). Changes in descriptive and collective norms (but not injunctive norms) were associated with changes in self-reported iron and folic acid consumption (P < 0.001 for both norms).

Conclusion

Our results show that social norms can be improved and that these improvements are associated with positive behavioural changes. A social norms-based approach may help promote iron and folic acid consumption in India.

Dietary Diversity and Its Associations with Anemia among Women of Reproductive Age in Rural Odisha, India

The aim of this study is to examine diet diversity, predictors associated with it, and its associations with anemia among non-pregnant women of reproductive age in rural India. Baseline data from the Reductions in Anemia through Normative Innovations (RANI) project were used and included 980 non-pregnant women aged 15-49 years from Odisha, India. The Food and Agriculture Organization's Minimum Dietary Diversity for Women (MDD-W) was used to assess diet diversity. Anemia was determined by hemoglobin level and categorized as normal (hemoglobin ≥ 12 g/dL), mild (11 ≤ hemoglobin <12 g/dL) and moderate/severe (hemoglobin < 11 g/dL). Multivariable logistic regression was used to examine factors associated with diet diversity, and multinomial logistic regression for associations between diet diversity and anemia. Forty-four percent of women were classified as having a diverse diet (MDD-W ≥5). Women with higher education level, belonging to a scheduled caste (vs. tribe), and higher body mass index had higher odds of a diversified diet (p < .05 for all). A more diverse diet was associated with 30% of lower odds of mild anemia (odds ratio = 0.7, 95% confidence interval: 0.5-0.98, p = .035), however, no statistically significant associations were found for moderate/severe anemia. Diet diversity was inversely associated with prevalence of mild anemia among non-pregnant women of reproductive age in rural India.

A Social Norms-Based Intervention Improves Dietary Diversity among Women in Rural India: The Reduction in Anemia through Normative Innovations (RANI) Project

Diet diversity has an important role in the prevention and treatment of anemia. Based on formative research in the community and the theory of normative social behavior, we designed an intervention to improve diet diversity among women of reproductive age. Our study, the Reduction in Anemia through Normative Innovations (RANI) Project, investigated the effect of a social norms-based intervention on diet diversity among women of reproductive age. We randomized villages in Odisha, India, into treatment or control arms, with a minimum of one village buffer between them. We assessed exposure to the intervention by frequency of self-reported images seen from the participatory learning modules, videos watched, and number of hemoglobin tests administered. We assessed diet diversity with the Food and Agriculture Organization’s Minimum Dietary Diversity for Women (MDD-W) questionnaire. We used multiple logistic regression to examine the associations between intervention and diet diversity, adjusting for covariates. Compared with baseline, diet diversity score increased in both treatment and control groups. The odds of having a diverse diet was 47% higher in the treatment group. Higher level of exposure to the RANI intervention was associated with a better diet diversity score, indicating that the intervention was effective in improving diet quality.

Addressing anaemia in pregnancy in rural plains Nepal: A qualitative, formative study

Maternal anaemia prevalence in low-income countries is unacceptably high. Our research explored the individual-, family- and community-level factors affecting antenatal care uptake, iron folic acid (IFA) intake and consumption of micronutrient-rich diets among pregnant women in the plains of Nepal. We discuss how these findings informed the development of a home visit and community mobilisation intervention to reduce anaemia in pregnancy. We used a qualitative methodology informed by the socio-ecological framework, conducting semi-structured interviews with recently pregnant women and key informants, and focus group discussions with mothers-in-law and fathers. We found that harmful gender norms restricted women's access to nutrient-rich food, restricted their mobility and access to antenatal care. These norms also restricted fathers' role to that of the provider, as opposed to the caregiver. Pregnant women, mothers-in-law and fathers lacked awareness about iron-rich foods and how to manage the side effects of IFA. Fathers lacked trust in government health facilities affecting access to care and trust in the efficacy of IFA. Our research informed interventions by (1) informing the development of intervention tools and training; (2) informing the intervention focus to engaging mothers-in-law and men to enable behaviour change; and (3) demonstrating the need to work in synergy across individual, family and community levels to address power and positionality, gender norms, trust in health services and harmful norms. Participatory groups and home visits will enable the development and implementation of feasible and acceptable strategies to address family and contextual issues generating knowledge and an enabling environment for behaviour change.

How gender norms affect anemia in select villages in rural Odisha, India: A qualitative study

BACKGROUND

In India, 50% of women of reproductive age, compared with 23% of men, have iron deficiency anemia. Extant research focuses on biological, not social, determinants of this disparity.

OBJECTIVES

The aim of this study was to examine how gender norms may affect anemia prevalence among women in rural India.

METHODS

We conducted 16 focus group discussions (N = 124) with women of reproductive age, husbands, and mothers-in-law and 25 key informant interviews in four villages in Odisha, India.

RESULTS

We identified the following themes that help explain how inequitable gender norms exacerbate anemia among women from different castes and tribes: Due to a double burden of work outside the home and completing the majority of unpaid work in the home, women lack time to visit health centers to get tested for anemia and to obtain iron supplements. Women are expected to prioritize the health of their family over their own, thus affecting their access to health care. Women's autonomy to leave the house to seek health care is limited. Men are the primary breadwinners for the family, but often spend their money on alcohol, rather than on iron-rich food for the household. Intra-household food allocation favors men, in-laws, and children, thus women serve their family first, often being left with little food.

CONCLUSION

Anemia reduction interventions need to include examination of the whole social context to successfully increase iron supplement use and iron-rich food intake. Understanding how gender norms contribute to anemia could change the narrative from a biomedical to a social justice issue.

Examining intentions to take iron supplements to inform a behavioral intervention: The Reduction in Anemia through Normative Innovations (RANI) project

BACKGROUND

More than half of women of reproductive age in India have anemia. Over the last decade, India has made some progress towards reducing anemia in pregnant women, but non-pregnant women, who make up the largest sub group of people with anemia, are largely disregarded.

OBJECTIVES

The objective of this paper is to examine intentions to take iron supplements and factors associated with intentions to inform a social norms-based behavioral intervention to increase uptake of iron supplements and reduce anemia in Odisha, India.

METHODS

We collected data from 3,914 randomly sampled non-pregnant women of reproductive age in 81 villages. We conducted a survey and took hemocue (anemia level) readings from each participant. We analyzed data using linear regression models beginning with demographics and social norms and adding other factors such as self-efficacy to take iron supplements, anemia risk perception, and knowledge about anemia in a subsequent model.

RESULTS

63% of women in our sample were anemic but less than 5% knew they were anemic. Despite national guidelines that all women of reproductive age should take weekly iron supplements to prevent anemia, less than 3% of women in our sample were currently taking them. While actual use was low, intentions were rather high. On a five point Likert scale where higher numbers meant more intentions to take supplements, average intentions were above the midpoint (M = 3.48, SD = 1.27) and intentions and iron supplement use were significantly correlated (r = .10, p < .001). Both injunctive norms and collective norms were associated with intentions to take iron supplements but descriptive norms were not. Other significant factors included age, breastfeeding, knowledge, self-efficacy, and outcome expectations. The final model accounted for 74% of the variance in iron supplement intentions.

CONCLUSIONS

In this context, where the actual behavior is low but intentions to enact the behavior are high, starting an intervention with injunctive norms messaging (expectations around the behavior) and self-efficacy to enact the behavior is the step we recommend based on our results. As an intervention unfolds and iron supplement use increases, descriptive norms messaging (that people are indeed taking iron supplements) may add value.

Determinants of work capacity (predicted VO2max) in non-pregnant women of reproductive age living in rural India

BACKGROUND

The negative impact of anemia on work capacity has been studied extensively in male and female workers; however, the simultaneous contributions of confounding variables such as physical activity, as well as other behavioral and sociodemographic characteristics have not been considered. The purpose of this study was to examine cross-sectionally the multivariable correlates of work capacity in non-pregnant women (n = 330) living in rural India.

METHODS

The Reduction in Anemia through Normative Innovations (RANI) Project is a norms-based, clustered randomized controlled trial to reduce anemia among women (15-49 years) living in Odisha, India between 2018 and 2021. For the larger trial, 89 clusters of villages were randomized into treatment and control groups on a 1:1 basis. Women (2055/group) living in 15 selected clusters (40-41 villages) were then randomly selected for data collection. The sampling design also randomly-generated a subset (n = 375) of non-pregnant participants who performed a modified Queen's College Step Test (QCST) and who wore an activity monitor for 3 days. Predicted work capacity (VO_2max) was determined using the QCST. Levels (h/day) of daily reclining, sitting, standing, walking (steps/day), and energy expenditure (MET∙h/day) were determined using an ActivPAL accelerometer. Hemoglobin concentrations (g/dL) were determined using a HemoCue photometer. Predetermined hierarchical (non-multilevel) regression models tested the independent associations between the primary study variables of interest (physical activity, hemoglobin concentrations) and predicted VO_2max, while adjusting for age, body mass index (BMI: kg/m²), education, parity, and dietary diversity score.

RESULTS

Approximately 61% of the participants had anemia (Hb < 12 g/dL). Age² (β = - 0.01; 95% CI: - 0.01, 0.00), BMI (β = - 0.19; 95% CI:-0.28, - 0.09), educational attainment (β = - 1.35; 95% CI: - 2.34, - 0.36), and MET∙h/day (β = 0.19; 95% CI: 0.00, 0.38) were significant and independent determinants of work capacity. Hemoglobin concentration was marginally associated with work capacity in the presence of the other covariables (β = 0.22; 95% CI:-0.02, 0.47).

CONCLUSIONS

Our data indicate that factors other than anemia are important correlates of work capacity and should be considered when promoting the health and economic capacity of rural Indian women.

Interventions to increase adherence to micronutrient supplementation during pregnancy: a systematic review

Prenatal micronutrient supplements are cost‐effective in reducing nutritional deficiencies and adverse pregnancy and birth outcomes. However, poor adherence remains a potential barrier to the successful implementation of these supplementation programs. This systematic review assessed the effectiveness of interventions designed to increase adherence to prenatal micronutrient supplementation. Following the Cochrane Collaboration Methodology, literature searches were conducted in six electronic databases and gray literature (on July 24, 2020), and abstract screening, data extraction, and risk of bias assessment were conducted independently by two reviewers. We included 22 studies. Interventions that resulted in increased adherence were most of the education‐based strategies, consumption monitoring by volunteer health workers or family members, SMS reminders, free provision of supplements, a multicomponent intervention with community mobilization, and a participatory action research intervention. In several studies, increased adherence was accompanied by beneficial effects on pregnancy and birth outcomes. Given the heterogeneity of study designs and methods used to define and measure adherence, a meta‐analysis was not appropriate. We identified several potentially effective strategies to improve supplementation adherence, which may need to be adapted to specific contexts when considered for program implementation. However, additional high‐quality studies are critically needed to effectively guide policies and programs.

Moving beyond individual barriers and identifying multi-level strategies to reduce anemia in Odisha India

BACKGROUND

To reduce the prevalence of anemia, the Indian government recommends daily iron and folic acid supplements (iron supplements) for pregnant women and weekly iron supplements for adolescents and all women of reproductive age. The government has distributed free iron supplements to adolescents and pregnant women for over four decades. However, initial uptake and adherence remain inadequate and non-pregnant women of reproductive age are largely ignored. The aim of this study is to examine the multilevel barriers to iron supplement use and to subsequently identify promising areas to intervene.

METHODS

We conducted a qualitative study in the state of Odisha, India. Data collection included key informant interviews, focus group discussions with women, husbands, and mothers-in-law, and direct observations in health centers, pharmacies and village health and nutrition days.

RESULTS

We found that at the individual level, participants knew that iron supplements prevent anemia but underestimated anemia prevalence and risk in their community. Participants also believed that taking too many iron supplements during pregnancy would "make your baby big" causing a painful birth and a costly cesarean section. At the interpersonal level, mothers-in-law were not supportive of their daughters-in-law taking regular iron supplements during pregnancy but husbands were more supportive. At the community level, participants reported that only pregnant women and adolescents are taking iron supplements, ignoring non-pregnant women altogether. Unequal gender norms are also an upstream barrier for non-pregnant women to prioritize their health to obtain iron supplements. At the policy level, frontline health workers distribute iron supplements to pregnant women only and do not follow up on adherence.

CONCLUSIONS

Interventions should address multiple barriers to iron supplement use along the socio-ecological model. They should also be tailored to a woman's reproductive life course stage: adolescents, pregnancy, and non-pregnant women of reproductive age because social norms and available services differ between the subpopulations.
