Sociodemographic profiles were various, with 14,541 (16.5{\%}) aged ≥60 years, 20,166 (22.9{\%}) aged <30 years, 27,766 (32.1{\%}) without postsecondary education, 15,397 (19.7{\%}) with household income <{\texteuro}1200/month, and 8258 (10.6{\%}) with household income {\texteuro}3700/month. Compared to employed individuals, unemployed and retired participants were less likely to be informed about the study through other sources than through television (adjusted ORs 0.56-0.83, P<.001). Participants reporting up to secondary education were also less likely to have learned about the study through radio newscasts, newspaper articles, Internet, and advice than through television (adjusted ORs 0.60-0.77, P<.001). Conclusions: Television broadcasts appear to permit the recruitment of e-cohort participants with diverse sociodemographic backgrounds, including socioeconomically disadvantaged individuals who are usually difficult to reach and retain in long-term epidemiologic studies. These findings could inform future Web-based studies regarding the development of promising targeted or general population recruitment strategies.
