, a randomized controlled trial, aimed to help young, low-income overweight and obese mothers prevent weight gain by promoting stress management, healthy eating, and physical activity. This paper describes recruitment challenges and reports demographic characteristics affecting enrollment.
Participants who were African American or Non-Hispanic White were recruited from the Special Supplemental Nutrition Program for Women, Infants, and Children (WIC) in Michigan. We faced numerous recruitment challenges and learned that several strategies facilitated recruitment. Logistic regression analyses were performed to examine demographic characteristics that affect enrollment.
Women who had a higher body mass index (BMI, OR 1.06, 95% CI 1.02 - 1.10); were at late postpartum, (OR 1.24, 95% CI 1.10 - 1.40), were breastfeeding (OR 5.0, 95% CI 2.34 -10.65); or were at early postpartum and breastfeeding (OR 0.42, 0.22 - 0.81) were more likely to enroll than their counterparts. Compared to African American women, Non-Hispanic White women were more likely to enroll (OR 1.77, 1.29 - 2.42). Also, women who were non-smokers (OR 0.54, 95% CI 0.40 - 0.73) or had a higher education were more likely to enroll (OR 1.21, 1.04 - 1.42) than those who smoked or had a lower education.
Future lifestyle behavioral intervention studies for similar target audiences may consider tailoring their recruitment messages based on relevant participant demographic characteristics identified as potential determinants of enrollment in this study.
一项随机对照试验旨在通过促进压力管理、健康饮食和体育活动，帮助年轻、低收入的超重及肥胖母亲预防体重增加。本文描述了招募方面的挑战，并报告了影响入组的人口统计学特征。
从密歇根州妇女、婴儿和儿童特别补充营养计划（WIC）中招募非裔美国或非西班牙裔白人参与者。我们面临诸多招募挑战，并了解到几种策略有助于招募。进行逻辑回归分析以检验影响入组的人口统计学特征。
体重指数（BMI）较高的女性（比值比[OR]为1.06，95%置信区间[CI]为1.02 - 1.10）；处于产后晚期的女性（OR为1.24，95%CI为1.10 - 1.40），正在进行母乳喂养的女性（OR为5.0，95%CI为2.34 - 10.65）；或处于产后早期且正在进行母乳喂养的女性（OR为0.42，95%CI为0.22 - 0.81）比其他女性更有可能入组。与非裔美国女性相比，非西班牙裔白人女性更有可能入组（OR为1.77，95%CI为1.29 - 2.42）。此外，不吸烟的女性（OR为0.54，95%CI为0.40 - 0.73）或受教育程度较高的女性（OR为1.21，95%CI为1.04 - 1.42）比吸烟或受教育程度较低的女性更有可能入组。
未来针对类似目标受众的生活方式行为干预研究，可考虑根据本研究中确定的作为入组潜在决定因素的相关参与者人口统计学特征，调整其招募信息。
