In terms of retention, multiple logistic regressions revealed that enrollees under age 60 (P < .001) and those with higher baseline self-efficacy were less likely to participate in the 12-month follow-up (P = .03), but with these exceptions, those participating were very similar to those not participating in the follow-up. Conclusions: A single personalized mailing increases enrollment in Internet-based weight loss. eHealth programs offer great potential for recruiting large numbers of participants, but they may not reach those at highest risk. Patient characteristics related to each of these important factors may be different, and more comprehensive analyses of determinants of enrollment, engagement, and retention in eHealth programs are needed. %M 17513282 %R 10.2196/jmir.9.2.e11 %U //www.mybigtv.com/2007/2/e11/ %U https://doi.org/10.2196/jmir.9.2.e11 %U http://www.ncbi.nlm.nih.gov/pubmed/17513282
