Feasibility of following up a representative sample of the adult population in Barcelona (Spain)

The objective of this work was to study the feasibility of following up a representative sample of the adult population of Barcelona 8 years after the baseline study. We selected a random sample (n = 100) of the 1161 participants who consented to be re-contacted. We contacted 66 participants: 52 (78.8%) agreed to participate in the follow-up, three (4.5%) had died, four (6.1%) had moved, and seven (10.6%) declined to participate in the follow-up. The participation rate in the feasibility study was 52%. In conclusion, the results of our study show a good feasibility of conducting a follow-up study 8 years after the baseline study.
