据报道，由于气候变化导致地表水和地下水盐度增加，已对孟加拉国沿海居民的健康构成巨大威胁。然而，人们对这种盐度对水相关疾病风险的影响程度以及如何在现场减轻这种风险知之甚少。这项研究探讨了与水有关的疾病与沿海盐度以及社会人口学和人体测量因素之间的关联。我们对 527 户家庭进行了问卷调查，其中 273 名受试者来自孟加拉国无盐区农村地区，254 名受试者来自孟加拉国沿海农村盐碱区。逻辑回归分析表明，盐度地区患水源性疾病、水冲疾病和与水有关的疾病的概率分别比非盐度地区高8%、14%和11%。然而，研究还发现，即使在盐度较高的地区，以雨水作为饮用水源的人患水相关疾病的机会也较少，而属于“体重指数不足”的人患与水有关的疾病的机会也较多。总体而言，结果表明，长期保留雨水和解决以社区为基础的粮食安全和营养计划应是有效的对策，以减少沿海人口健康问题的风险，并在土地盐碱化的威胁下维持他们的生活。[图表]。
An increase in surface and ground-water salinity due to climate change is reported to have become a great threat to the health of coastal inhabitants in Bangladesh. However, little is known about how much such salinity affects the risk of water-related diseases and how such risk can be mitigated in the field. This research examines the association between water-related diseases and coastal salinity along with sociodemographic and anthropometric factors. We conduct questionnaire surveys with 527 households: 273 subjects from the non-salinity and 254 subjects from the salinity rural coastal areas of Bangladesh. The logistic regression analysis demonstrates that the probability of suffering from water-borne, water-washed and water-related diseases are 8%, 14% and 11% higher in the salinity areas than in the non-salinity areas, respectively. However, it is also identified that people who consume rainwater as a drinking source even in the salinity areas have less chances and people who belong to "underweight body mass index" have more chances of being affected by water-related diseases. Overall, the results suggest that the long-term reservation of rainwater and addressing community-based food security & nutrition programs shall be effective countermeasures to reduce the risk of health problems in the coastal population and to sustain their lives even under the threat of land salinity.[GRAPHICS].
