Abstract
OBJECTIVES
This study examines the associations between water insecurity, self-reported physical health, and objective measures of biological health among 225 Awajún adults (107 women; 118 men) living in the Peruvian Amazon, a "water-abundant" region.
METHODS
A survey, which included multiple measures of self-reported physical health, and objective measures of biological health such as blood pressure and nutritional and immune biomarkers.
RESULTS
Greater water insecurity was associated with multiple measures of self-reported physical health, including higher incidence of reported diarrhea, nausea, back pain, headaches, chest pain, fatigue, dizziness, overall poor perceived health, and "being sick." These symptoms align with the physical strain associated with water acquisition and with drinking contaminated water. A significant association between higher water insecurity and lower systolic blood pressure emerged, which may be linked to dehydration. None of the other biomarkers, including those for nutrition, infection, and stress were significantly associated with water insecurity scores.
CONCLUSIONS
These analyses add to the growing body of research examining the associations between water insecurity and health. Biocultural anthropologists are well-positioned to continue probing these connections. Future research will investigate relationships between measures of water insecurity and biomarkers for gastrointestinal infection and inflammation in water-scarce and water-abundant contexts.
