BACKGROUND
Recruiting a diverse sample of pregnant women for clinical research is a challenging but crucial task for improving obstetric services and maternal and child health outcomes.
OBJECTIVE
To compare the feasibility and cost of recruiting pregnant women for survey research using social media-based and clinic-based approaches.
METHODS
Advertisements were used to recruit pregnant women from the social media website Facebook. In-person methods were used to recruit pregnant women from the outpatient clinic of a large, tertiary care center. In both approaches, potential respondents were invited to participate in a 15-minute Web-based survey. Each recruitment method was monitored for 1 month. Using bivariate statistics, we compared the number, demographic characteristics, and health characteristics of women recruited and the cost per completed survey for each recruitment method.
RESULTS
The social media-based approach recruited 1178 women and the clinic-based approach recruited 219 women. A higher proportion of subjects recruited through social media identified as African American (29.4%, 207/705 vs 11.2%, 20/179), reported household incomes <US $30,000 per year (56.8%, 409/720 vs 25.8%, 47/182), reported being in early pregnancy (18.6%, 135/726 vs 10.4%, 19/183 first trimester), and rated their health as fair or poor (22.2%, 160/722 vs 8.2%, 15/183; all P<.001). A smaller proportion of subjects recruited through social media had earned a college degree (21.3%, 153/717 vs 62.3%, 114/183) and were married or in a domestic partnership (45.7%, 330/722 vs 72.1%, 132/183; all P<.001). Social media-based recruitment costs were US $14.63 per completed survey, compared with US $23.51 for clinic-based recruitment.
CONCLUSIONS
Web-based recruitment through a social networking platform is a feasible, inexpensive, and rapid means of recruiting a large, diverse sample of pregnant women for survey research.
背景
招募多样化的孕妇样本用于临床研究是一项具有挑战性但至关重要的任务，对于改善产科服务以及母婴健康结局而言。
目的
比较使用基于社交媒体和基于诊所的方法招募孕妇进行调查研究的可行性和成本。
方法
通过广告从社交媒体网站脸书招募孕妇。采用面对面的方法从一家大型三级医疗中心的门诊招募孕妇。在两种方法中，均邀请潜在受访者参与一项15分钟的网络调查。每种招募方法均监测1个月。使用双变量统计，我们比较了每种招募方法招募的女性数量、人口统计学特征、健康特征以及每份完成调查的成本。
结果
基于社交媒体的方法招募了1178名女性，基于诊所的方法招募了219名女性。通过社交媒体招募的受试者中，非裔美国人的比例更高（29.4%，207/705对11.2%，20/179），报告家庭年收入<30,000美元的比例更高（56.8%，409/720对25.8%，47/182），报告处于早孕阶段的比例更高（18.6%，135/726对10.4%，19/183为孕早期），且将自身健康评为一般或较差的比例更高（22.2%，160/722对8.2%，15/183；所有P<0.001）。通过社交媒体招募的受试者中，获得大学学位的比例较小（21.3%，153/717对62.3%，114/183），已婚或处于家庭伴侣关系的比例较小（45.7%，330/722对72.1%，132/183；所有P<0.001）。基于社交媒体的招募成本为每份完成调查14.63美元，而基于诊所的招募成本为23.51美元。
结论
通过社交网络平台进行网络招募是一种可行、廉价且快速的方法，可招募大量多样化的孕妇样本用于调查研究。
