目的：体重指数（BMI）升高的孕妇很难被纳入生活方式研究。本文（1）总结了招募孕妇参加随机试验的策略，（2）报告了招募统计数据及其相关性。材料与方法：非裔美国人和白色女性，BMI ≥25，胎龄<16周，主要通过产科诊所招募到妊娠和产后健康研究中。妇女完成了一个简短的筛选表，如果最初合格，电话筛选。我们比较了随机化与非随机化的特征。结果如下：最初合格的孕妇（N = 1578），确定通过直接招聘的研究人员，间接招聘的诊所工作人员在产科诊所，并通过广告自我转介。在这些妇女中，54.0%（850人）接受了进一步筛查，43.5%（685人）完全合格。在符合条件的女性中，58.8%（403例）计划接受基线访视，33.3%（228例）接受随机化。总体招募率为14.4%。招募的参与者是多样化的（44%是非洲裔美国人），基线时平均妊娠12.6周。随机化（与非随机化）的女性更有可能拥有手机，在家里或工作中可以使用带互联网的电脑，并下载播客。结论：虽然这项研究没有达到招募目标，但在怀孕早期招募了相对较大且多样化的孕妇样本。招募BMI升高的女性进行行为生活方式干预具有挑战性，特别是在具有特征的女性中，包括电话和互联网接入较少以及使用播客的经验有限。本研究注册于NCT 02260518。
Purpose: Pregnant women with elevated body mass index (BMI) are difficult to recruit into lifestyle studies. This article (1) summarized strategies to recruit pregnant women into a randomized trial, and (2) reported recruitment statistics and their correlates. Materials and Methods: African American and white women with BMI ≥25 and gestational age <16 weeks were recruited primarily through obstetric clinics into the Health in Pregnancy and Postpartum study. Women completed a brief screening form, and if initially eligible, a phone screening. We compared characteristics of those randomized versus not randomized. Results: Initially eligible pregnant women (N = 1578) were identified through direct recruitment by research staff, indirect recruitment by clinic staff at obstetric clinics, and self-referrals through advertisements. Of these women, 54.0% (850) were reached for further screening, and 43.5% (685) were fully eligible. Among eligible women, 58.8% (403) were scheduled for a baseline visit, and 33.3% (228) were randomized. The overall recruitment yield was 14.4%. Recruited participants were diverse (44% African Americans) and averaged 12.6 weeks gestation at baseline. Randomized (vs. nonrandomized) women were more likely to own a cell phone, have access to a computer with internet at home or work, and have downloaded a podcast. Conclusions: Although this study did not reach the recruitment goal, a relatively large and diverse sample of pregnant women were recruited early in pregnancy. Recruiting women with elevated BMI for a behavioral lifestyle intervention is challenging, particularly among women with characteristics, including less phone and internet access and limited experience in using podcasts. This study is registered at NCT02260518.
