“…The proportion of partial respondents in our study was small and similar to that observed in the web-based health survey of 47,859 Swedish women mentioned above [24]. It has been observed that responses to a web version of a questionnaire are usually more complete than the responses to a printed questionnaire [6].…”

Feasibility of recruiting a birth cohort through the Internet: the experience of the NINFEA cohort

et al. 2007

View full text Add to dashboard Cite

The NINFEA cohort is an Italian birth cohort aiming at recruiting pregnant women through the Internet and following-up their children. To understand whether Internet-based recruitment was feasible we started a pilot in July 2005 targeted to pregnant women visiting the hospitals of the city of Turin (900,000 inhabitants), where we advertised the study. For this purpose we constructed a website (www.progettoninfea.it), with on-line questionnaires to be completed during pregnancy and at 6 and 18 months after delivery. Participants' characteristics were compared with those of women giving birth in Turin, which are routinely released as individual anonymous records. We also compared complete with partial respondents. We also carried out a survey of 122 women giving birth in the main Turin obstetric hospital to estimate the proportion of pregnant women with access to the Internet and awareness of the NINFEA cohort. By December 2006, we had recruited 670 women. Participation was associated with being older, a university graduate, primiparous and born in Italy. Complete response (n = 633) was associated with being primiparous and participation after the first trimester. In the survey, 66% (95% confidence interval: 56-74%; n = 80) of the women had access to the Internet and 42% (33-51%; n = 51) were aware of the study; 6.5% (2.9-12.5%; n = 8) had participated in the NINFEA cohort. Our study indicates that recruitment of an Internet-based birth cohort is feasible. As with many other types of birth cohort study, the participants are a self-selected sample. To minimise selection bias analyses should therefore be limited to internal comparisons.

“…However, this is a constant concern irrespective of method and might not be larger in web-studies. This was shown by Ekman et al, in a population-based cohort study of 50,000 women [26]. Although there were some suggestions of a non-response bias, there was no difference between the web and paper mode used, which has also been confirmed by others [37][38][39].…”

“…A group uniquely identified in web-surveys are lurkers, participants that enter, start responding to, but do not complete a webquestionnaire. Lurkers are potentially easier to persuade to complete an already started web-questionnaire compared to a non-responder and thus constitute a unique opportunity of decreasing the drop out rate and therefore merit future research [26,27].…”

The successful and systematic collection of demographic and lifestyle data is central in the process of any epidemiological study. The traditionally used methods such as face-to-face and telephone interviews as well as paper-questionnaires are increasingly failing to produce good qualitative results within financially feasible limits. Tools that are better suited for the present dynamic populations are needed and the Internet presents a powerful alternative for the collection of data with several intrinsic features still unexplored.

“…New methods for contacting participants, which have been used in other more recently started studies, including use of internet, sms and e-mail, are currently being explored [92, [252][253][254][255][256][257][258][259][260][261][262].…”

The Generation R Study: design and cohort update 2012

et al. 2012

View full text Add to dashboard Cite

The Generation R Study is a population-based prospective cohort study from fetal life until young adulthood. The study is designed to identify early environmental and genetic causes of normal and abnormal growth, development and health during fetal life, childhood and adulthood. The study focuses on four primary areas of research: (1) growth and physical development; (2) behavioural and cognitive development; (3) diseases in childhood; and (4) health and healthcare for pregnant women and children. In total, 9,778 mothers with a delivery date from April 2002 until January 2006 were enrolled in the study. General follow-up rates until the age of 4 years exceed 75%. Data collection in mothers, fathers and preschool children included questionnaires, detailed physical and ultrasound examinations, behavioural observations, and biological samples. A genome wide association screen is available in the participating children. Regular detailed hands on assessment are performed from the age of 5 years onwards. Eventually, results forthcoming from the Generation R Study have to contribute to the development of strategies for optimizing health and healthcare for pregnant women and children.
