Article published in Epidemiology with two associated commentaries

In the issue of January of Epidemiology will appear an article based on the RECORD Study as well as two commentaries related to this article (the first one and the second one).

In this work related to the prevalence of type 2 diabetes, we investigated the different factors that may influence participation of populations in the RECORD Cohort Study.

Epidemiologists usually pay a particular attention to "selection processes" that lead to retain in or exclude from their studies people who are particular with respect to the exposures or to the health outcomes of interest.

In these analyses, we found that a high individual education level and that residing nearby the health centers involved in the recruitment, in a socially advantaged neighborhood, or in a low population density neighborhood were associated with increased odds of participation in the RECORD Study.

In our work interested in the relationship between neighborhood socioeconomic status and type 2 diabetes, we showed that it is possible in certain cases to account for these selection biases in the analyses.
