背景：在家中暴露于有毒化学品是一个日益关注的问题。本报告概述了一项研究的招募、数据收集方法、用于收集数据的工具以及参与者人口统计数据，该研究旨在研究影响家庭环境中环境毒素暴露的行为，也称为SUPERB（产品使用研究和暴露相关行为）。方法：方法涉及三个不同的平台：电话采访、基于互联网的调查和基于家庭的监测。SUPERB的目的是：第一，比较数据收集平台的可行性、可接受性和可靠性;第二，提供纵向的基于人口的数据，描述与食物消费、时空活动和家庭产品使用有关的行为的季节性和长期变化。来自北方加州的家庭（父母一方和一个孩子）和来自加州中部的老年人（55岁以上）。北方加州家庭的父母（n = 499）平均年龄为36岁，47.1%是拉丁美洲人或非白人，10.2%的人用西班牙语接受调查。大多数入组儿童（n = 566）年龄在6岁以下（82.7%）。老年人登记（n = 156），平均年龄为66岁，23.7%是拉丁美洲人或非白人，但只有2.6%完成了调查在Spanish.Conclusions：我们发现，过抽样是成功地提高招聘代表性不足的亚组，如那些教育程度低，从而增加了我们的研究样本的多样性。尽量减少参与者时间的协议，例如，使用条形扫描器和秤而不是关于家用产品使用情况的调查表，以及由建立信任关系的工作人员执行这些协议，导致纵向数据收集计划的高保留率。在自愿参加纵向互联网调查的人中，只有一小部分人在填写调查表时保持一致。未来的报告将提供关键信息的横截面，季节性和纵向模式的暴露相关的行为在幼儿，幼儿的父母，和老年人。
Background: Exposure to toxic chemicals in the home is a growing concern. This report presents an overview of the recruitment, methods for data collection, instruments used to collect data, and participant demographics for a study examining behaviors that influence exposure to environmental toxins in the home environment, also known as SUPERB (Study of Use of Products and Exposure Related Behaviors).Methods: The methods involved three different platforms: telephone interviews, internet-based surveys, and home-based monitoring. The purposes of SUPERB were: first, to compare data collection platforms with regard to feasibility, acceptability and reliability; and second, to provide longitudinal population-based data characterizing seasonal and long-term changes in exposure-related behaviors including food consumption, temporal-spatial activity, and household product use.Results: Two cohorts of households were enrolled: families (one parent and one child) from northern California and older individuals (age 55+) from central California. Parents (n = 499) in Northern California families were on average 36 years of age, 47.1% were Latino or nonwhite, and 10.2% took the survey in Spanish. Most of the children enrolled (n = 566) were under 6 years (82.7%). The older adults enrolled (n = 156) were, on average, 66 years of age and 23.7% were Latino or nonwhite, but only 2.6% completed the survey in Spanish.Conclusions: We found that oversampling was successful in improving recruitment of under-represented subgroups, such as those with low education, thereby increasing diversity of our study sample. Protocols that minimize participant time, e.g., use of bar scanners and scales rather than questionnaires regarding use of household products, and the implementation of these protocols by staff who built relationships of trust, resulted in high retention over a longitudinal data collection scheme. A relatively small fraction of those who volunteer for longitudinal internet surveys are consistent in filling them out. Future reports will provide critical information on cross-sectional, seasonal and longitudinal patterns of exposure related behaviors in young children, parents of young children, and older adults.
