A recruitment plan was designed to recruit healthy children (9–14 years) in a trial testing the 1-year effect of corn soluble fiber supplementation on bone mass. We evaluated the effectiveness and costs of the recruitment strategies used in this trial. Methods: The recruitment plan included “Traditional” (mailings, flyers, posters, visits, snowball, etc.) or “Online” (email campaigns, social media, website, etc.) strategies. All strategies led to the pre-screening online form, which asked how they learned about the study. This analysis includes the number of pre-screenings and enrollment (consents signed), ineligibility, socio-demographics, and costs per strategy. Differences were analyzed using ANOVA or chi-square. Results: 649 individuals completed the pre-screening; 37.1 % came from “Traditional”, 46.7 % from “Online”, 2.6 % from “Other”, and 13.6 % from “Unknown” strategies. The most successful strategies were related to Florida International University (posting flyers around campus and email campaigns). The main reasons for ineligibility were obesity (38.9 %) or outside the age range (22.7 %). A total of 48.4 % of the children enrolled came from “Traditional”, 50.2 % from “Online”, and 1.4 % from “Other” strategies. The cost per screened participant was $1112 for “Traditional” and $512 for “Online” strategies, and the cost per enrolled participant was $2704 for “Traditional” and $1454 for “Online” strategies. The highest costs were staff salary. Conclusion: “Online” strategies were more effective and had a lower implementation cost than “Traditional” strategies, although these were also important in achieving the recruitment goal. Future pediatric trials should consider some of these strategies and their costs.</div><div><span><span>ClinicalTrials.gov</span><svg><path></path></svg></span> registry number: <span><span>NCT02916862</span><svg><path></path></svg></span></div></div>","PeriodicalId":10636,"journal":{"name":"Contemporary clinical trials","volume":"147 ","pages":"Article 107715"},"PeriodicalIF":2.0,"publicationDate":"2024-10-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142444903","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
