Abstract
Background – Millions of people living in coastal areas in South-east Asia have been experiencing an increasing number of land-falling cyclones and subsequent inundations: these inundations cause extreme salinization of local drinking water sources, such as ponds. Daily consumption of these sources contributes significantly to overall sodium intake of the population, especially immediately after a cyclone. Low-sodium alternatives, such as rainwater harvesting and solar distillation, can reduce sodium intake, lower blood pressure and potentially reduce incidence of myocardial infarction (MI) and stroke. In this study we further quantified the MI and stroke prevention potential of saline-low drinking water alternatives in a coastal population. Methods – We developed mathematical models to estimate salt concentration in ponds and (drinking water) salt intake by a coastal population in Bangladesh. Scenarios of salt intake following an inundation and intake in case of successful implementation of small/large scale rainwater harvesting or solar distillation devices were evaluated. Salt intake of each scenario was used to model 10-year risk of MI and stroke incidence and mortality in a simulated coastal population >45 years of age. Results – We will present the results of our models and give a detailed estimation of expected MI, stroke and CVD (mortality) risks before and after and inundation, as well as risk reductions under each alternative drinking water supply scenario. In addition, a cost benefit analysis of each scenario will be presented. Conclusions – This study demonstrates the MI and stoke reduction-potential of several alternative drinking water solutions for salinity affected areas. Considering the current trend of this environmental health problem and the large number of people affected, prompt action is required. This includes further exploration and implementation of alternative drinking water solutions for prevention of salinity-induced CVDs.
