Low water access as a gendered physiological stressor: Blood pressure evidence from Nepal

Brewis, Alexandra, Choudhary, Neetu, Wutich, Amber·2019·American Journal of Human Biology

Abstract

OBJECTIVES: The study aims to test novel proposed biocultural pathways linking the stressful lived experience of water insecurity to elevated blood pressure, a risk factor for chronic disease. Using the case of Nepal, where women have primary responsibility for managing household water, allows testing for potentially gendered mechanisms that exacerbate negative physiological consequences of water insecurity for women relative to men. METHODS: Data are from the nationally representative 2016 Nepal Demographic and Health Survey (DHS), N = 8633 women and 6209 men. Multiple regression models tested effects of low household water access on systolic and diastolic blood pressure, as stress biomarkers, comparing women to men. Key covariates included HFIAS food insecurity scores, household wealth class (high, medium, low), and body mass index. RESULTS: In this cross-sectional study, low water access was consistently associated with higher women's systolic and diastolic blood pressure across all wealth levels. The strongest results were for the lowest wealth households, where low water access is concentrated. Higher food insecurity was also associated with higher systolic blood pressure values in women in these households. Men showed no such effects. CONCLUSIONS: This is the first study, to our knowledge, to demonstrate a consistent and direct association between living with water insecurity and elevated blood pressure measures. Findings support the proposition that the stress of living with water insecurity could manifest as chronic disease risk. In the Nepali case, the proposed mechanism appears highly gendered, reflecting the culturally prescribed responsibilities women particularly face for managing household water. Living with food insecurity compounds further the apparent effects.

Each is checked against this paper’s own text: does it say what the citing paper says it does?

  • In Nepal, having intermediate and low water access was associated with higher systolic and diastolic blood pressure levels in women, while men's blood pressure was not statistically different; elevated levels of blood pressure were highest for women with the least water access.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
