One approach to reduce resulting losses in statistical power and potential biases is to follow up migrants at their new residence. We describe the follow-up of migrants who were eligible for participation in a trial of a new questionnaire to measure adult mortality in Niakhar, Senegal. We conducted a short inquiry in the migrant's last known household to obtain contact information and then attempted to contact and interview 661 migrants who resided in Dakar, Mbour, and rural areas close to Niakhar. About two-thirds of migrants were successfully enrolled in the study. Having a contact phone number and knowing the name of the head of compound at destination increased the likelihood of successful enrollment. Following up migrants in demographic studies is feasible in low- and middle-income countries, including long-term migrants who have not been contacted for extended periods of time. specialized SENEGAL 108 050 32 1 38-57 2020 1525-822X https://www.documentation.ird.fr/hor/fdi:010077306 10.1177/1525822x19879892 1525-822X [F B010077306] https://www.documentation.ird.fr/hor/fdi:010077306 https://www.documentation.ird.fr/intranet/publi/depot/2020-10-22/010077306.pdf Accès réservé (Intranet de l'IRD) IRD - Base Horizon / Pleins textes 2019-12-12 2025-02-24 fdi:010077306 fre
