This study examined primary health care use and accessibility among adolescents living in the United Arab Emirates. In a cross-sectional study, we collected health care use, sociodemographic and residential data for a sample of 6363 adolescents. Logistic regression modelling was used to examine predictors of health care use. The most-consulted health professionals were dentists or orthodontists, family doctors and eye specialists. Local adolescents were more likely to attend public clinics/hospitals than private facilities, while the opposite was true for expatriates. In the previous 12 months 22.6% of the participants had not obtained the health care they needed and 19.5% had not had a routine health check-up. Common reasons for not obtaining care were busy schedules, dislike/fear of doctors and long waiting times. Predictors of not obtaining needed care included nationality and income, while those for having a routine check-up were mother's education and car ownership. Improvements to the health care sector may increase health care accessibility among adolescents.
