Abstract Objective: Water plays a critical role in the production of food and preparation of nutritious meals, yet few studies have examined the relationship between water and food insecurity. The primary objective of this study, therefore, was to examine how experiences of household water insecurity (HWI) relate to experiences of household food insecurity (HFI) among a pastoralist population living in an arid, water-stressed region of northern Kenya. Design: We implemented the twelve-item Household Water Insecurity Experiences (HWISE, range 0–36) Scale and the nine-item Household Food Insecurity Access Scale (HFIAS, range 0–27) in a cross-sectional survey to measure HWI and HFI, respectively. Data on socio-demographic characteristics and intake of meat and dairy in the prior week were collected as covariates of interest. Setting: Northern Kenya, June–July 2019. Participants: Daasanach pastoralist households ( n 136) from seven communities. Results: In the prior 4 weeks, 93·4 % and 98·5 % of households had experienced moderate-to-severe HWI and HFI, respectively. Multiple linear regression analyses indicated a strong association between HWI and HFI. Each point higher HWISE score was associated with a 0·44-point (95 % CI: 0·22, 0·66, P = 0·003) higher HFIAS score adjusting for socio-economic status and other covariates. Conclusions: These findings demonstrate high prevalence and co-occurrence of HWI and HFI among Daasanach pastoralists in northern Kenya. This study highlights the need to address HWI and HFI simultaneously when developing policies and interventions to improve the nutritional well-being of populations whose subsistence is closely tied to water availability and access.

Coping with water insecurity despite access and abundance in the urban Amazon
ABSTRACT Research on household water insecurity continues to overemphasize water scarcity and rural contexts, resulting in a poorer understanding of water insecurity in urban, water-abundant settings. At the same time, while the dimensions of water insecurity include availability, access, utilization and stability, current instruments focus on access to water, thus, inadequately explore people's experiences utilizing available water. This study aimed to characterize and explore the impacts of household water insecurity on residents of the city of Belém, Pará, Brazil, where water is available and access to piped municipal water is common, but its provision and quality vary. We applied the Household Water Insecurity Experiences Scale (HWISE) to evaluate water insecurity in 188 households (110 LSES; 78 HSES). In a subset of 47 households, we complemented the HWISE with a novel instrument, developed via participant observation, that assessed all points of water access and use within the home. Per HWISE, 28% of households were water insecure, with a higher proportion of water insecurity occurring in LSES households. Data collected via our complementary instrument indicate that HWISE underestimated water insecurity in our sample, as 87% of the subset households reported issues affecting their utilization of water regardless of household water insecurity status.

ABSTRACT The Household Water Insecurity Experiences (HWISE) and Individual Water Insecurity Experiences (IWISE) Scales are globally suitable tools for comparably measuring water insecurity experiences among households and adults, respectively. The potential range for HWISE and IWISE scores is 0–36. When the WISE Scales were first published, scores of 12 and higher were considered indicative of water insecurity, but additional cut-points are needed to provide more nuanced insights. We therefore sought to develop a practical set of cut-points for the WISE Scales using HWISE data from 13 sites across 12 countries (n = 3,293) and nationally representative samples of IWISE data from 38 countries collected by the Gallup World Poll (n = 52,343). We selected cut-points in water insecurity scores to establish four ordinal categories: no-to-marginal (0–2), low (3–11), moderate (12–23), and high (24–36) water insecurity. These categories were monotonically associated with increasing odds of reporting water dissatisfaction and helped to differentiate the breadth of water insecurity across populations with heterogenous water insecurity experiences and frequencies. These four water insecurity categories can be used to better understand how water insecurity may be related to livelihoods, health, and well-being, both at low and high water insecurity.more » « less

Objective Progress towards equitable and sufficient water has primarily been measured by population-level data on water availability. However, higher-resolution measures of water accessibility, adequacy, reliability and safety (ie, water insecurity) are needed to understand how problems with water impact health and well-being. Therefore, we developed the Household Water InSecurity Experiences (HWISE) Scale to measure household water insecurity in an equivalent way across disparate cultural and ecological settings. Methods Cross-sectional surveys were implemented in 8127 households across 28 sites in 23 low-income and middle-income countries. Data collected included 34 items on water insecurity in the prior month; socio-demographics; water acquisition, use and storage; household food insecurity and perceived stress. We retained water insecurity items that were salient and applicable across all sites. We used classical test and item response theories to assess dimensionality, reliability and equivalence. Construct validity was assessed for both individual and pooled sites using random coefficient models. Findings Twelve items about experiences of household water insecurity were retained. Items showed unidimensionality in factor analyses and were reliable (Cronbach’s alpha 0.84 to 0.93). The average non-invariance rate was 0.03% (threshold <25%), indicating equivalence of measurement and meaning across sites. Predictive, convergent and discriminant validity were also established. Conclusions The HWISE Scale measures universal experiences of household water insecurity across low-income and middle-income countries. Its development ushers in the ability to quantify the prevalence, causes and consequences of household water insecurity, and can contribute an evidence base for clinical, public health and policy recommendations regarding water.more » « less

null (Ed.)Objective To assess the links between structural and household determinants of household water insecurity and test three water insecurity measures against self-reported diarrhoea, dengue fever and perceived stress in the middle-income and low-income urban areas of Torreón, Mexico. Design Cross-sectional household survey conducted in two waves (rainy and dry seasons). Participants 500 households selected via multistage cluster sample in selected communities. Socioeconomic status determined the selection of participant neighbourhoods; five were identified in low socioeconomic status neighbourhoods and five in low-medium socioeconomic status neighbourhoods. We examine how the context of urban water provision is related to a new cross-culturally valid Household Water Insecurity Experiences (HWISE) Scale. Primary outcome measures The HWISE Scale, self-reported diarrhoea, dengue fever and the Perceived Stress Scale. Results Water system intermittency (adjusted OR (AOR) 3.96, 95% CI 2.40 to 6.54, p<0.001), unpredictability (AOR 2.24, 95% CI 1.34 to 3.74, p=0.002) and the dry season (AOR 3.47, 95% CI 2.18 to 5.52, p<0.001) were structural correlates of the HWISE Scale. This study also found that the HWISE Scale was associated with two health outcomes, self-reported diarrhoea (AOR 1.09, 95% CI 1.03 to 1.15, p=0.002) and perceived stress (β=0.28, SE=0.07, t =4.30, p<0.001), but not self-reported dengue fever (AOR 1.02, 95% CI 0.98 to 1.06). A 3-item hygiene subscore and a 3-item water worry subscore were also both positively associated with self-reported diarrhoea and perceived stress. Conclusion Short-form screeners of water insecurity may be useful for assessing certain health risks by lay survey workers in settings with limited healthcare resources, particularly in lieu of more expensive microbiological tests that require specialised training and facilities.more » « less

Introduction A wide range of water-related problems contribute to the global burden of disease. Despite the many plausible consequences for health and well-being, there is no validated tool to measure individual- or household-level water insecurity equivalently across varying cultural and ecological settings. Accordingly, we are developing the Household Water Insecurity Experiences (HWISE) Scale to measure household-level water insecurity in multiple contexts. Methods and analysis After domain specification and item development, items were assessed for both content and face validity. Retained items are being asked in surveys in 28 sites globally in which water-related problems have been reported (eg, shortages, excess water and issues with quality), with a target of at least 250 participants from each site. Scale development will draw on analytic methods from both classical test and item response theories and include item reduction and factor structure identification. Scale evaluation will entail assessments of reliability, and predictive, convergent, and discriminant validity, as well as the assessment of differentiation between known groups. Ethics and dissemination Study activities received necessary ethical approvals from institutional review bodies relevant to each site. We anticipate that the final HWISE Scale will be completed by late 2018 and made available through open-access publication. Associated findings will be disseminated to public health professionals, scientists, practitioners and policymakers through peer-reviewed journals, scientific presentations and meetings with various stakeholders. Measures to quantify household food insecurity have transformed policy, research and humanitarian aid efforts globally, and we expect that an analogous measure for household water insecurity will be similarly impactful.more » « less
