We aimed to describe 17 months of experience with household recruitment of live births for the National Children's Study in Queens, a highly urban, diverse borough of New York City (NYC), and to assess predictors of recruitment success.
Recruitment data (enumeration, pregnancy screening of age-eligible women, identification of pregnancies, and consent) for the period of January 2009 through May 2010 were calculated. Geographic information systems were used to create 11 community-level variables for each of the 18 study segments where recruitment occurred, using US Census, NYC Office of Vital Statistics, NYC Department of City Planning, and NYC Police Department data. Recruitment yields were analyzed with respect to these variables at the segment level.
Enumeration identified 4889 eligible women, of whom 4333 (88.6%) completed the pregnancy screener. At least 115 births were lost because of an inability of the pregnancy screener to identify pregnant women, whereas another 115 could be expected to be lost because of missed enumerations and pregnancy screeners. The consent rate was 60.3%. Segments with higher percentages of low birth weight had higher enumeration, pregnancy screening, and consent rates.
In a highly immigrant, urban setting, households could be approached for recruitment of women to participate in the National Children's Study with consent rates equal to those experienced in clinical settings. Refinement of the pregnancy screener and other recruitment materials presents an opportunity to optimize recruitment, improve the representativeness of study participants, and improve the cost-effectiveness of study execution.
我们旨在描述纽约市皇后区（纽约市一个高度城市化、多元化的行政区）全国儿童研究（National Children's Study）中 17 个月的家庭招募活产经验，并评估招募成功的预测因素。
计算了 2009 年 1 月至 2010 年 5 月期间的招募数据（计数、符合年龄条件的妇女妊娠筛查、妊娠识别和同意）。使用美国人口普查、纽约市生命统计办公室、纽约市城市规划局和纽约市警察局的数据，为每个发生招募的 18 个研究片段创建了 11 个社区级别的变量。在片段级别上，根据这些变量分析了招募收益。
计数确定了 4889 名符合条件的妇女，其中 4333 名（88.6%）完成了妊娠筛查。由于妊娠筛查器无法识别孕妇，至少有 115 例分娩被遗漏，而由于错过计数和妊娠筛查器，预计另外有 115 例分娩会被遗漏。同意率为 60.3%。出生体重较低比例较高的片段具有较高的计数、妊娠筛查和同意率。
在一个高度移民的城市环境中，通过同意率与临床环境中相同的方式，可以接近家庭招募妇女参与全国儿童研究。对妊娠筛查器和其他招募材料进行改进，为优化招募、提高研究参与者的代表性以及提高研究执行的成本效益提供了机会。
