A new study led by Boston University School of Public Health (BUSPH) researchers indicates that concerns about selection bias from Internet recruiting may be unfounded, at least in research on reproductive-age women.
In the study, published online in the journal Epidemiology, the research team found that several perinatal associations in an Internet-based Danish pregnancy study known as Snart Gravid closely mirrored associations in the larger Danish population.
“The majority of associations were very similar for the Internet-recruited population and the remainder of Danish women giving birth,” the researchers wrote. “Although we cannot be confident that our results would apply to other populations and associations than those studied here, our findings indicate that selection bias may not be an important concern in prospective cohort studies of reproduction that recruit and follow women via the Internet.”
Lead study author Dr. Elizabeth Hatch, professor of epidemiology at BUSPH, said the study “eases concerns that some have had regarding the use of the Internet for enrollment and follow-up of epidemiologic studies.”
