Population-based recruitment of a cohort of women who are currently pregnant or who may become pregnant in a given timeframe presents challenges unique to identifying pregnancy status or the likelihood of future pregnancy. Little is known about the performance of individual eligibility items on pregnancy screeners although they are critical to participant recruitment. This paper examined the patterns and respondent characteristics of key pregnancy screener items used in a large national study.
Cross-sectional analyses were conducted. Descriptive statistics and multivariable logistic regression models were used to examine nonresponse patterns to three questions (currently pregnant, trying to get pregnant and able to get pregnant). The questions were asked of 50,529 women in 17 locations across the US, as part of eligibility screening for the National Children's Study Vanguard Study household-based recruitment.
Most respondents were willing to provide information about current pregnancy, trying, and able to get pregnant: 99.3% of respondents answered all three questions and 97.4% provided meaningful answers. Nonresponse ranged from 0.3 to 2.5% for individual items. Multivariable logistic regression results identified small but statistically significant differences in nonresponse by respondent age, marital status, race/ethnicity-language, and household-based recruitment group.
The high levels of response to pregnancy-related items are impressive considering that the eligibility questions were fairly sensitive, were administered at households, and were not part of a respondent-initiated encounter.
以人群为基础招募在特定时间段内处于孕期或可能怀孕的女性群体，在确定妊娠状态或未来怀孕可能性方面存在独特挑战。尽管妊娠筛查中的个体合格项目对参与者招募至关重要，但对于这些项目的表现却知之甚少。本文研究了一项大型全国性研究中使用的关键妊娠筛查项目的模式及应答者特征。
进行横断面分析。使用描述性统计和多变量逻辑回归模型来研究对三个问题（当前怀孕、试图怀孕和能够怀孕）的无应答模式。在美国17个地点的50529名女性中询问了这些问题，作为全国儿童研究先锋研究基于家庭招募的合格性筛查的一部分。
大多数应答者愿意提供有关当前怀孕、试图怀孕和能够怀孕的信息：99.3%的应答者回答了所有三个问题，97.4%提供了有意义的答案。单个项目的无应答率在0.3%至2.5%之间。多变量逻辑回归结果显示，在应答者年龄、婚姻状况、种族/族裔-语言和基于家庭的招募组方面，无应答存在虽小但具有统计学意义的差异。
考虑到合格性问题相当敏感、在家庭中进行询问且并非应答者主动发起的接触的一部分，对与怀孕相关项目的高应答率令人印象深刻。
