Project description:BackgroundMore 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.ObjectivesThe 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.MethodsWe 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.Results63% 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.ConclusionsIn 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.

Project description:BackgroundIn 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.ObjectivesThe aim of this study was to examine how gender norms may affect anemia prevalence among women in rural India.MethodsWe 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.ResultsWe 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.ConclusionAnemia 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.

Project description:Background: More than half of women of reproductive age in India are anemic. Anemia is associated with increased risk of preterm delivery, higher maternal mortality and contributes to fatigue, which affects women's work productivity. The World Health Organization (WHO) recommends daily oral iron and folic acid (IFA) supplements during pregnancy and weekly supplements for women of reproductive age. Government programs and global donors have distributed and promoted IFA supplements in India for over four decades. However, initial intake and compliance remain inadequate. Objectives: This protocol describes the formative research phase of a larger study, called the Reduction in Anemia through Normative Innovations (RANI) Project, which will test, through a randomized controlled trial, the hypothesis that a social norms-based behavioral intervention in Odisha, India will improve uptake of IFA supplements and reduce anemia among reproductive age women as compared to usual care. The focus of this paper is on the formative research required to develop a sound intervention. We will examine socio-normative barriers to and facilitators of IFA supplement uptake. Methods and analysis: Based on the Theory of Normative Social Behavior, we will adopt a mixed-method, multilevel approach. We will collect data using focus groups, in-depth interviews, observations, Rapid Participatory Ethnographic Evaluation and Research (PEER) techniques, and perceptual mapping methods. Our sample includes reproductive age women (pregnant and not pregnant), their husbands, their mothers/in law and key stakeholders. Before collecting the data, and after analyzing the results, we will hold convenings in India to engage key stakeholders in collaborative design. Following the intervention design, we will test components of the intervention, gather user feedback and fine-tune as necessary. Impact: This study will contribute to the social norms and behavioral intervention research and inform policymakers about the value of adopting a socio-normative approach.

Project description:Norms and normative multiagent systems have become the subjects of interest for many researchers. Such interest is caused by the need for agents to exploit the norms in enhancing their performance in a community. The term norm is used to characterize the behaviours of community members. The concept of normative multiagent systems is used to facilitate collaboration and coordination among social groups of agents. Many researches have been conducted on norms that investigate the fundamental concepts, definitions, classification, and types of norms and normative multiagent systems including normative architectures and normative processes. However, very few researches have been found to comprehensively study and analyze the literature in advancing the current state of norms and normative multiagent systems. Consequently, this paper attempts to present the current state of research on norms and normative multiagent systems and propose a norm's life cycle model based on the review of the literature. Subsequently, this paper highlights the significant areas for future work.

Project description:BackgroundThe high prevalence of anemia in resource-constrained settings calls for easy-to-use, inexpensive screening tools. The Sanguina Smartphone App, an innovative tool for non-invasive hemoglobin estimation via color-sensitive, algorithm-based analysis of fingernail bed images, was validated in the United States. This study evaluates the performance of the App in a population with different socio-economic, ethnic, demographic and cultural composition in rural Bihar, India.MethodsFor 272 mainly adult patients of a private health centre, hemoglobin measurement with the App is compared with the gold standard laboratory blood analysis. For a second sample of 179 children attending pre-schools, hemoglobin measurement with the App is compared to the results of the HemoCue Hb 301, a point-of-care device using a small blood sample, serving as the reference standard for field-based settings.ResultsThe App reaches ±4.43 g/dl accuracy and 0.38 g/dl bias of comparator values in the clinic-based sample, and ±3.54 g/dl and 1.30 g/dl, respectively in the pre-school sample. After retraining the algorithm with the collected data, the validity of the upgraded version is retested showing an improved performance (accuracy of ±2.25 g/dl, bias of 0.25 g/dl), corresponding to the results of the original validation study from the United States.ConclusionsThe initial version of the App does not achieve the accuracy needed for diagnosis or screening. After retraining the algorithm, it achieves an accuracy sufficient for screening. The improved version with the potential for further adaptions is a promising easy-to-use, inexpensive screening tool for anemia in resource-constrained point-of-care settings.

Project description:While rates of malnutrition have declined over the last decade in India due to successful government interventions, the prevalence of anemia remains high. Staple foods provide almost 70% of the daily iron intake. As staple foods are a rich source of phytate, this ingested iron is poorly absorbed. Currently, 59% of children below 3 years of age, 50% of expectant mothers and 53% of women aged 15-19 years are anemic. The most common intervention strategy has been through the use of iron supplements. While the compliance has been low and supplies irregular, such high rates of anemia cannot be explained by iron deficiency alone. This review attempts to fit dietary and cooking practices, field-level diagnostics, cultural beliefs and constraints in implementation of management strategies into a larger picture scenario to offer insights as to why anemia continues to plague India. Since the rural Indian diet is predominantly vegetarian, we also review dietary factors that influence non-heme iron absorption. As a reference point, we also contrast anemia-related trends in India to the U.S.A. Thus, this review is an effort to convey a holistic evaluation while providing approaches to address this public health crisis.

Project description:Endotoxin exacerbates asthma. We designed the Louisa Environmental Intervention Project (LEIP) and assessed its effectiveness in reducing household endotoxin and improving asthma symptoms in rural Iowa children. Asthmatic school children (N = 104 from 89 homes) of Louisa and Keokuk counties in Iowa (aged 5-14 years) were recruited and block-randomized to receive extensive (education + professional cleaning) or educational interventions. Environmental sampling collection and respiratory survey administration were done at baseline and during three follow-up visits. Mixed-model analyses were used to assess the effect of the intervention on endotoxin levels and asthma symptoms in the main analysis and of endotoxin reduction on asthma symptoms in exploratory analysis. In the extensive intervention group, dust endotoxin load was significantly reduced in post-intervention visits. The extensive compared with the educational intervention was associated with significantly decreased dust endotoxin load in farm homes and less frequent nighttime asthma symptoms. In exploratory analysis, dust endotoxin load reduction from baseline was associated with lower total asthma symptoms score (Odds ratio: 0.52, 95% confidence interval: 0.29-0.92). In conclusion, the LEIP intervention reduced household dust endotoxin and improved asthma symptoms. However, endotoxin reductions were not sustained post-intervention by residents.

Project description:BackgroundMigration from rural areas of India contributes to urbanisation and lifestyle change, and dietary changes may increase the risk of obesity and chronic diseases. We tested the hypothesis that rural-to-urban migrants have different macronutrient and food group intake to rural non-migrants, and that migrants have a diet more similar to urban non-migrants.Methods and findingsThe diets of migrants of rural origin, their rural dwelling sibs, and those of urban origin together with their urban dwelling sibs were assessed by an interviewer-administered semi-quantitative food frequency questionnaire. A total of 6,509 participants were included. Median energy intake in the rural, migrant and urban groups was 2731, 3078, and 3224 kcal respectively for men, and 2153, 2504, and 2644 kcal for women (p<0.001). A similar trend was seen for overall intake of fat, protein and carbohydrates (p<0.001), though differences in the proportion of energy from these nutrients were <2%. Migrant and urban participants reported up to 80% higher fruit and vegetable intake than rural participants (p<0.001), and up to 35% higher sugar intake (p<0.001). Meat and dairy intake were higher in migrant and urban participants than rural participants (p<0.001), but varied by region. Sibling-pair analyses confirmed these results. There was no evidence of associations with time in urban area.ConclusionsRural to urban migration appears to be associated with both positive (higher fruit and vegetables intake) and negative (higher energy and fat intake) dietary changes. These changes may be of relevance to cardiovascular health and warrant public health interventions.

Project description:BackgroundReducing salt intake has been proposed to prevent cardiovascular disease in India. We sought to determine whether salt reductions would be beneficial or feasible, given the worry that unrealistically large reductions would be required, worsening iodine deficiency and benefiting only urban subpopulations.Methods and resultsFuture myocardial infarctions (MI) and strokes in India were predicted with a Markov model simulating men and women aged 40 to 69 in both urban and rural locations, incorporating the risk reduction from lower salt intake. If salt intake does not change, we expect ~8.3 million MIs (95% CI: 6.9-9.6 million), 830,000 strokes (690,000-960,000) and 2.0 million associated deaths (1.5-2.4 million) per year among Indian adults aged 40 to 69 over the next three decades. Reducing intake by 3 g/day over 30 years (-0.1 g/year, 25% reduction) would reduce annual MIs by 350,000 (a 4.6% reduction; 95% CI: 320,000-380,000), strokes by 48,000 (-6.5%; 13,000-83,000) and deaths by 81,000 (-4.9%; 59,000-100,000) among this group. The largest decline in MIs would be among younger urban men, but the greatest number of averted strokes would be among rural men, and nearly one-third of averted strokes and one-fifth of averted MIs would be among rural women. Only under a highly pessimistic scenario would iodine deficiency increase (by <0.0001%, ~1600 persons), since inadequate iodized salt access--not low intake of iodized salt--is the major cause of deficiency and would be unaffected by dietary salt reduction.ConclusionsModest reductions in salt intake could substantially reduce cardiovascular disease throughout India.

Project description:OBJECTIVES:To study the trend in the prevalence of anaemia and low BMI among pregnant women from Eastern Maharashtra and evaluate if low BMI and anaemia affect pregnancy outcomes. DESIGN:Prospective observational cohort study. SETTING:Catchment areas of 20 rural primary health centres in four eastern districts of Maharashtra State, India. PARTICIPANTS:72?750 women from the Nagpur site of Maternal and Newborn Health Registry of NIH's Global Network, enrolled from 2009 to 2016. MAIN OUTCOME MEASURES:Mode of delivery, pregnancy related complications at delivery, stillbirths, neonatal deaths and low birth weight (LBW) in babies. RESULTS:Over 90% of the women included in the study were anaemic and over a third were underweight (BMI <18?kg/m2) and with both conditions. Mild anaemia at any time during delivery significantly increased the risk (Risk ratio; 95% confidence interval (RR;(95%?CI)) of stillbirth (1.3 (1.1-1.6)), neonatal deaths (1.3 (1-1.6)) and LBW babies (1.1 (1-1.2)). The risks became even more significant and increased further with moderate/severe anaemia any time during pregnancy for stillbirth (1.4 (1.2-1.8)), neonatal deaths (1.7 (1.3-2.1)) and LBW babies (1.3 (1.2-1.4)).,. Underweight at anytime during pregnancy increased the risk of neonatal deaths (1.1 (1-1.3)) and LBW babies (1.2;(1.2-1.3)).The risk of having stillbirths (1.5;(1.2-1.8)), neonatal deaths (1.7;(1.3-2.3)) and LBW babies (1.5;(1.4-1.6)) was highest when - the anaemia and underweight co-existed in the included women. Obesity/overweight during pregnancy increased the risk of maternal complications at delivery (1.6;(1.5-1.7)) and of caesarean section (1.5;(1.4-1.6)) and reduced the risk of LBW babies 0.8 (0.8-0.9)). CONCLUSION:Maternal anaemia is associated with enhanced risk of stillbirth, neonatal deaths and LBW. The risks increased if anaemia and underweight were present simultaneously. TRIAL REGISTRATION NUMBER:NCT01073475.
