Urbanization and Infectious Disease
The United Nations currently estimates that over half of the global population has lived in cities since 2017 and that this proportion is continuing to grow, particularly in the Global South. While urbanization is not new, increased population density combined with accelerating rates of (re)emerging and noncommunicable diseases as well as growing economic disparities has created new challenges to human health and well‐being. Here, I examine peri‐…
Contextualizing adherence: Iron supplementation treatment among Peruvian caretakers and their anemic children
This article describes an ethnographic study of adherence to iron supplementation protocols in 50 anemic preschoolers and their caregivers living in a peri-urban district in Lima, Peru. I use aspects of the syndemic approach to highlight the challenges caregivers face in following the recommended treatment and burden of treatment theory to develop a deeper understanding of adherence in a community with persistent childhood anemia. Interpreting ad…
Intestinal microbiota composition and efficacy of iron supplementation in Peruvian children
OBJECTIVE: Despite repeated public health interventions, anemia prevalence among children remains a concern. We use an evolutionary medicine perspective to examine the intestinal microbiome as a pathway underlying the efficacy of iron-sulfate treatment. This study explores whether gut microbiota composition differs between anemic children who respond and do not respond to treatment at baseline and posttreatment and if specific microbiota taxa rem…
Revisiting geophagy: An evolved sickness behavior to microbiome‐mediated gastrointestinal inflammation
Geophagy, the consumption of clay or similar substances, is known as an evolved behavior that protects vulnerable populations, such as pregnant women and children, against gastrointestinal injury. However, perplexing questions remain, like the presence of geophagy in the absence of overt gastrointestinal infection and the potential causal relationship between geophagy and iron deficiency anemia. In this review, we hypothesize that geophagy is an …
Adiposity and pathogen exposure: An investigation of response to iron supplementation and hypothesized predictors in anemic pre‐school‐aged children living in a dual burden environment
OBJECTIVES: Peruvians are experiencing rapid dietary and lifestyle changes, resulting in a phenomenon known as the "dual burden of disease." A common manifestation of the dual burden in individuals is the co-occurrence of overweight and anemia. Despite recent initiatives introduced to address these concerns, rates continue to be public health concerns. This study investigates the relationship between immune activation and lack of response to iron…
Child, caretaker, and community: Testing predictors of anemia and response to iron supplementation in Peruvian preschool‐aged children
The findings of this study document an association between children's anemia status and their nutritional and ecological environment, highlighting the importance of examining anemia within a specific context to better understand the factors driving this important health problem
Iron and infection: An investigation of the optimal iron hypothesis in Lima, Peru
OBJECTIVES: This article explores the optimal iron hypothesis through secondary data analysis of the association between hemoglobin levels and morbidity among children living in Canto Grande, a peri-urban community located on the outskirts of Lima, Peru. METHODS: Risk ratios were used to test whether lower iron status, assessed using the HemoCue B-Hemoglobin System, was associated with an increased relative risk of morbidity symptoms compared to …
