The Influence of Public or Private Paediatric Health Care on Vaccination Coverages in Children in Catalonia (Spain)

Abstract

[Abstract]: Background: Maintaining high vaccination coverages is necessary in order to control vaccine-preventable diseases. We studied vaccination coverages in a representative sample of 630 children aged <3 years in Catalonia in order to determine the relationship between vaccination coverages and socioeconomic factors. Methods: Sampling was carried out in a representative sample of the health regions in Catalonia stratified according to habitat. A sample of 630 parents of children aged <3 years born in October 2001 were interviewed by telephone. Information collected included sociodemographic data, type of health care provider (public or private) and information on vaccination coverage for the basic plus booster immunization series (BBI) which consisted of: four DTP, four OPV, one MMR and the doses of Hib and MenC necessary according to age of administration of the first dose. Results: A total of 87.62% of the children were vaccinated with the BBI series, and no statistically significant differences in coverage between public (87.93%) and private (88.30%) paediatric providers, or between social classes (high: 87.58%, low: 88.81%) were found. Vaccination coverage was associated with attending a day-care centre (OR: 1.89; 95% CI: 1.12–3.21) and maternal university education (OR: 1.84; 95% CI: 1.01–3.33). Conclusion: Vaccination coverages are high and are similar between types of provider, probably due to preventive policies which have made a concerted effort to ensure universal vaccination.
