背景：我们正在布拉德福德出生的大型前瞻性多种族出生队列 (BiB) 中调查怀孕期间和胎儿生长期间的消毒副产品暴露情况。许多先前的流行病学研究因缺乏个人用水行为数据以及对潜在混杂因素的调整不完整而受到限制。 目标：描述 BiB 队列中怀孕期间的个人用水量和与水相关的活动，并根据人口/生活方式特征检查这些行为的变异性。 方法：在 BiB 队列中（妊娠 28 周左右）招募孕妇时，由访谈者填写了一份包含生活方式、环境、种族和健康的基线调查问卷。调查问卷包括关于典型每日自来水消耗量、水过滤习惯以及怀孕期间淋浴、沐浴和游泳的频率和持续时间的问题。对 BiB 队列中 11,472 名女性的自来水消耗、淋浴、沐浴和游泳模式进行了分析。结果：初步结果显示，该队列中的孕妇平均每天消耗 1.6 升自来水，其中大部分自来水消耗发生在家里，无论就业状况如何。平均每天花 22 分钟淋浴和/或沐浴。只有 7.3% 的女性报告在怀孕期间游泳。初步结果表明，根据种族、吸烟状况和年龄，自来水消耗量和淋浴/沐浴时间存在差异。结论：已知不良胎儿生长结果与种族、母亲年龄和吸烟有关，我们的结果表明，未来的流行病学分析可能需要针对这些变量进行调整，以避免残留混杂因素。
Background: We are investigating disinfection by-product exposure during pregnancy and fetal growth in the large prospective multi-ethnic Born in Bradford (BiB) birth cohort. Many previous epidemiological studies have been limited by lack of data on individual water use behaviours and incomplete adjustment for potential confounders.Objectives: To describe individual water consumption and water-related activities during pregnancy in the BiB cohort, and to examine variability of these behaviours according to demographic/lifestyle characteristics.Methods: At recruitment to the BiB cohort (around 28 weeks gestation) pregnant women completed a baseline questionnaire encompassing lifestyle, environment, ethnicity, and health, administered by interviewer. The questionnaire included questions on typical daily consumption of tap water, water filtering habits and frequency and duration of showering, bathing and swimming whilst pregnant. Patterns of tap water consumption, showering, bathing and swimming were analysed for 11,472 women in the BiB cohort.Results: Preliminary results show that pregnant women in the cohort consume, on average, 1.6 litres of tap water per day with the majority of tap water consumption occurring at home regardless of employment status. On average, 22 minutes per day were spent showering and/or bathing. Only 7.3% of women reported swimming during pregnancy. Preliminary results suggest there are differences in tap water consumption and time spent showering/bathing according to ethnicity, smoking status and age.Conclusions: Adverse fetal growth outcomes are known to be associated with ethnicity, maternal age and smoking, and our results suggest that future epidemiological analyses may need to be adjusted for these variables to avoid residual confounding.
