摘要

背景砷（As）是一种有毒元素，可导致人类出现各种健康问题。人们接触砷的主要途径是饮用被高浓度砷污染的水，尤其是在孟加拉国。以往的研究表明，尿砷浓度可以反映个人的砷暴露和新陈代谢情况。本研究旨在调查年龄、性别和社会经济状况等因素对儿童尿砷浓度的影响，以及饮用水砷（WAs）水平的影响。我们测量了 UAs（391 名儿童的子集）和 WAs 水平，并收集了有关人口和社会经济特征的信息。结果我们发现，年龄较小的儿童（β = 197.95，95% 置信区间 [CI]：111.97 至 283.94）、女性儿童（β = 93.95，95% 置信区间 [CI]：8.49 至 179.40）和父亲受教育程度较低的儿童（β = 138.结论本研究得出结论，儿童的砷暴露量和 UAs 浓度可能因其年龄、性别和社会经济地位而异。因此，在评估与砷有关的健康风险时应考虑这些因素。

Demographic and socioeconomic determinants of urinary arsenic concentration for elementary school children in Bangladesh

Background

Arsenic (As) is a toxic element that can lead to various health issues in humans. The primary exposure to As is through the consumption of water contaminated with high As levels, particularly in Bangladesh. Previous studies have shown that urinary arsenic (UAs) concentration can reflect As exposure and metabolism in individuals. However, little is known about how other factors, such as age, sex, and socioeconomic status, may affect UAs concentrations in children.

Objective

This study aimed to investigate the influence of factors such as age, sex, and socioeconomic status on UAs concentrations in children, in addition to the impact of drinking water arsenic (WAs) levels.

Methods

We conducted our study on elementary school-going children aged 8‒11 years from rural Araihazar in Bangladesh. We measured UAs (available for a subset of 391 children) and WAs levels and collected information on demographic and socioeconomic characteristics. We employed regression analysis and t-tests to analyze the data.

Results

Our findings revealed that younger children (β = 197.95, 95% confidence interval [CI]: 111.97 to 283.94), female children (β = 93.95, 95% CI: 8.49 to 179.40), and children with less educated fathers (β = 138.03, 95% CI: 26.47 to 249.58) had higher UAs levels, particularly when they consumed water with high As content.

Conclusion

The study concludes that children’s As exposure and UAs concentration may vary depending on their age, sex, and socioeconomic status. Therefore, these factors should be considered when assessing the health risks associated with As.
