背景资料：由于海平面上升、旋风和风暴潮以及上游淡水的抽取，孟加拉国沿海地区自然来源的饮用水受到不同程度的盐度污染。目的：我们的目的是估计从饮用水源中摄入的盐，并检查可能解释妊娠期高血压季节性过度的环境因素。研究方法：孟加拉国沿海农村地区Dacope的水盐度数据（1998-2000年）来自孟加拉国环境和地理信息系统中心。在旱季（2009年10月至2010年3月），从343名怀孕的Dacope妇女获得饮用水源，24小时尿样和血压的信息。对969名孕妇（2008年7月至2010年3月）进行了基于医院的妊娠期高血压患病率测定。结果如下：在旱季，从饮用水中摄入的钠的平均估计量为5至16克/天，而在雨季为0.6至1.2克/天。平均每日尿钠排泄量为3.4 g/天（范围：0.4-7.7 g/天）。饮用浅管井水的女性比饮用雨水的女性更可能出现尿钠> 100 mmol/天[比值比（OR）= 2.05; 95%置信区间（CI），1.11-3.80]。妊娠期高血压的年住院患病率在旱季（OR = 12.2%，95%CI，9.5-14.8）高于雨季（OR = 5.1%，95%CI，2.91-7.26）。结论：该人群从饮用水中摄入的盐估计值超过了推荐限值。盐水侵入饮用水的问题有多种原因，而且可能因气候变化引起的海平面上升而加剧。
Background: Drinking water from natural sources in coastal Bangladesh has become contaminated by varying degrees of salinity due to saltwater intrusion from rising sea levels, cyclone and storm surges, and upstream withdrawal of freshwater. Objective: Our objective was to estimate salt intake from drinking water sources and examine environmental factors that may explain a seasonal excess of hypertension in pregnancy. Methods: Water salinity data (1998–2000) for Dacope, in rural coastal Bangladesh, were obtained from the Centre for Environment and Geographic Information System in Bangladesh. Information on drinking water sources, 24-hr urine samples, and blood pressure was obtained from 343 pregnant Dacope women during the dry season (October 2009 through March 2010). The hospital-based prevalence of hypertension in pregnancy was determined for 969 pregnant women (July 2008 through March 2010). Results: Average estimated sodium intakes from drinking water ranged from 5 to 16 g/day in the dry season, compared with 0.6–1.2 g/day in the rainy season. Average daily sodium excretion in urine was 3.4 g/day (range, 0.4–7.7 g/day). Women who drank shallow tube-well water were more likely to have urine sodium > 100 mmol/day than women who drank rainwater [odds ratio (OR) = 2.05; 95% confidence interval (CI), 1.11–3.80]. The annual hospital prevalence of hypertension in pregnancy was higher in the dry season (OR = 12.2%; 95% CI, 9.5–14.8) than in the rainy season (OR = 5.1%; 95% CI, 2.91–7.26). Conclusions: The estimated salt intake from drinking water in this population exceeded recommended limits. The problem of saline intrusion into drinking water has multiple causes and is likely to be exacerbated by climate change–induced sea-level rise.
