Applying focused ethnographic methods: examining implications of intracultural diversity for nutrition interventions

Addressing health disparities in food allergy: A Position Statement of the AAAAI Prior Authorization Task Force

Self-reported food allergies (FAs) affect approximately 8% of the US pediatric and approximately 10% of the adult population, which reflects potentially disproportionate increases among ethnically and racially minoritized groups. Multiple gaps and unmet needs exist regarding FA disparities. There is reported evidence of disparities in FA outcomes, and the FA burden may also be disproportionate in low-income families. Low family income has been associated with higher emergency care spending and insecure access to allergen-free food. Pharmacoinequity arises in part as a result of structural racism still experienced by historically marginalized populations today. Historically redlined communities continue to experience greater rates of neighborhood-level air pollution and indoor allergen exposure, lack of transportation to medical appointments, poverty, and lower prescription rates of necessary medications. Clinical research needs racially and ethnically diverse participation to ensure generalizability of research findings and equitable access to medical advances, but race reporting in clinical trials has been historically poor. Addressing health disparities in FA is a priority of clinical care, with professional organizations such as the American Academy of Allergy, Asthma & Immunology having a prominent role to play in mitigating the challenges faced by these individuals. In this position statement we recommend some key steps to address this important issue.

Behavioural drivers of suboptimal maternal and child feeding practices in Rwanda: An anthropological study

At 33% of under-5s, stunting rates in Rwanda remain stubbornly high, as do figures for maternal (25% of pregnant women) and childhood anaemia (37%). Intensive communication and education campaigns have provided caregivers with high levels of knowledge about best practices in Maternal, Infant and Young Child Nutrition (MIYCN), but this is not translating into the improved diets which could contribute to reducing rates of stunting. Deploying an anthropological approach via multi-module Focused Ethnographic Studies carried out within household case studies, the research team sought to understand drivers of suboptimal feeding practices in a sample of 30 households across all of Rwanda's districts. The sample included households with pregnant women as well as children in the 6-60 month age range. Analysed against a framework of proximal and underlying causes of under-nutrition, our results reveal gaps in the knowledge-capability-practice chain resulting from decisions and prioritisations taken by caregivers and heads-of-household. Pregnant women and mothers of young children possess high levels of knowledge about feeding themselves and their young children, but this is not reflected in decision-making and prioritisation around the acquisition and feeding of animal source foods, whose consumption is low among both groups. This was found to be true even in households which own and raise livestock. Turning to policy and programmes, we argue for a move towards incentivized human capital programming focusing on the 'last mile' behaviour change which is needed to translate knowledge and capability into better dietary choices.

Implementation and maintenance of infant dietary diversity in Zimbabwe: contribution of food and water insecurity

Background

Inadequate food and water resources negatively affect child health and the efficiency of nutrition interventions.

Methods

We used data from the SHINE trial to investigate the associations of food insecurity (FI) and water insecurity (WI) on mothers’ implementation and maintenance of minimum infant dietary diversity (MIDD). We conducted factor analysis to identify and score dimensions of FI (poor access, household shocks, low availability & quality), and WI (poor access, poor quality and low reliability). MIDD implementation (n = 636) was adequate if infants aged 12 months (M12) ate ≥ four food groups. MIDD maintenance (n = 624) was categorized into four mutually exclusive groups: A (unmet MIDD at both M12 and M18), B (unmet MIDD at M12 only), C (unmet MIDD at M18 only), and D (met MIDD at both M12 and M18). We used multivariable-adjusted binary logistic and multinomial regressions to determine likelihood of MIDD implementation, and of belonging to MIDD maintenance groups A-C (poor maintenance groups), compared to group D, respectively.

Results

Low food availability & quality were negatively associated with implementation (OR = 0.81; 0.69, 0.97), and maintenance (ORB = 1.29; 1.07, 1.56). Poor water quality was positively associated with implementation (OR = 1.25; 1.08, 1.44), but inconsistently associated with maintenance, with higher odds of infants being in group C (OR = 1.39; 1.08, 1.79), and lower odds of being in group B (OR = 0.80; 0.66, 0.96).

Conclusion

Food security should be prioritized for adequate implementation and maintenance of infant diets during complementary feeding. The inconsistent findings with water quality indicate the need for further research on WI and infant feeding.

Valuing the Diversity of Research Methods to Advance Nutrition Science

The ASN Board of Directors appointed the Nutrition Research Task Force to develop a report on scientific methods used in nutrition science to advance discovery, interpretation, and application of knowledge in the field. The genesis of this report was growing concern about the tone of discourse among nutrition professionals and the implications of acrimony on the productive study and translation of nutrition science. Too often, honest differences of opinion are cast as conflicts instead of areas of needed collaboration. Recognition of the value (and limitations) of contributions from well-executed nutrition science derived from the various approaches used in the discipline, as well as appreciation of how their layering will yield the strongest evidence base, will provide a basis for greater productivity and impact. Greater collaborative efforts within the field of nutrition science will require an understanding that each method or approach has a place and function that should be valued and used together to create the nutrition evidence base. Precision nutrition was identified as an important emerging nutrition topic by the preponderance of task force members, and this theme was adopted for the report because it lent itself to integration of many approaches in nutrition science. Although the primary audience for this report is nutrition researchers and other nutrition professionals, a secondary aim is to develop a document useful for the various audiences that translate nutrition research, including journalists, clinicians, and policymakers. The intent is to promote accurate, transparent, verifiable evidence-based communication about nutrition science. This will facilitate reasoned interpretation and application of emerging findings and, thereby, improve understanding and trust in nutrition science and appropriate characterization, development, and adoption of recommendations.

Complementary feeding and future health in Mexico. Introduction to the XI Nestlé Nutrition Conference

Nutrition in infancy provides an important window of opportunity to shape good health during childhood and adult life. The objective of this manuscript is to provide an introduction to the review articles that bring together the proceedings of the XI Nestlé Nutrition Conference "Complementary Feeding: A Piece of the Puzzle to Understand Future Health". The studies and description of complementary feeding practices in Mexico, from the Mexican National Health and Nutrition Survey 2012 (ENSANUT 2012), support the urgent need for strong policy actions to promote healthy eating and appropriate complementary feeding practices. Early interventions considering a life course approach and maternal and child nutrition are essential to prevent obesity, chronic disease and to ensure better health for the Mexican population.
