"Gender-Based Water Violence": Cross-Cultural Evidence for Severe Harm Associated With Water Insecurity for Women and Girls.

We examined how study participants in Indonesia and Peru viewed the relationship between water insecurity and women's health via thematic analysis of interviews and focus groups. Participants reported that water insecurity led to vaginal infections, miscarriage, premature births, uterine prolapse, poor nutrition, restricted economic opportunities, and intergenerational cycles of poverty. Participants in both countries stated that extreme burdens associated with water insecurity should be categorized as violence.

Water insecurity, self-reported physical health, and objective measures of biological health in the Peruvian Amazon.

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.

Ecosyndemics: The potential synergistic health impacts of highways and dams in the Amazon.

Ecosyndemics refer to disease interactions that result from environmental changes commonly caused by humans. In this paper, we push scholarship on ecosyndemics into new territory by using the ecosyndemic framework to compare two case studies-the Southern Interoceanic highway in Peru and the Belo Monte hydroelectric dam in Brazil-to assess the likelihood of socio-environmental factors interacting and leading to ill health in a syndemic fashion. Assessing these two case studies using an ecosyndemic perspective, we find that the construction of dams and highways in tropical forests create the conditions for increases in vector-borne illnesses, surges in sex work and sexually-transmitted infections, and increased psychological stress resulting from violence, delinquency, and the erosion of social cohesion.

The Index of Vulnerability: An anthropological method linking social-ecological systems to mental and physical health outcomes.

Researchers need measures of vulnerability that are grounded in explicit theoretical and conceptual frameworks, that are sensitive to local contexts, and that are easy to collect. This paper presents the Index of Vulnerability (IoV), a quantitative yet anthropologically-informed method connecting social-ecological systems to mental and physical health outcomes. The IoV combines measures of five life domains; food insecurity, water insecurity, access to healthcare, social support, and social status.

Microbial exposures in infancy predict levels of the immunoregulatory cytokine interleukin-4 in Filipino young adults.

Objectives: Infancy represents a window of development during which long-term immunological functioning can be influenced. In this study, we evaluate proxies of microbial exposures in infancy as predictors of interleukin-4 (IL-4) in young adulthood. IL-4 is an immunoregulatory cytokine that plays a role in the pathogenesis of atopic and allergic diseases.
