The aim of this cross-sectional study was to determine the immunity status of children to pertussis by socio-demographic characteristics in Eastern Turkey. The study sample consisted of 840 randomly selected and healthy children aged 0-71 months. The seroprevalence of pertussis was 30.1%. Age, parent education and economic status were not associated with the geometric mean titers (GMT) of pertussis antibody, while gender, residential area and the application number of diphtheriatetanus-whole-cell pertussis vaccine were associated with GMT. Most preschool children are susceptible to pertussis and current vaccination efforts do not provide adequate immunization. (c) 2004 The Royal Institute of Public Health. Published by Elsevier Ltd.
