| Resumen: | Objetivos: Describir la frecuencia de ansiedad, onicofagia y síndrome de piernas inquietas (SPI) en estudiantes de medicina y explorar la relación entre los mismos. Materiales y métodos: Participaron 315 estudiantes del primer al quinto año de medicina de una universidad privada de Lima. Se administraron la Escala de Ansiedad de Beck (BAI), una escala Likert para onicofagia, el Inventario de Estudios Epidemiológicos de SPI (García - Borreguero) y el Inventario de SPI (Grupo Internacional de SPI). Resultados: Se halló la frecuencia de ansiedad (61,3%), onicofagia (52,63%) y SPI (9,29%). Ser hombre es un factor protector para ansiedad (razón de prevalencia (RP) = 0,74; p = 0,001; IC 95% = 0,63 û 0,89). Existe asociación entre sintomatología ansiosa y SPI (RP =2,52; p = 0,036; IC 95% = 1,06 û 6); y entre sintomatología ansiosa y onicofagia (RP = 1,47; p = 0,002; IC 95% = 1,15 û 1,87). La presencia de onicofagia y SPI tenía asociación con sintomatología ansiosa (RP = 5,37; p = 0,023; IC 95% = 1,26 û 22,82). No se encontró asociación significativa entre SPI y onicofagia. Conclusiones: Existe una asociación entre ansiedad y SPI; y entre ansiedad y onicofagia; pero no entre SPI y onicofagia. (AU)^iesObjectives: The present work describes the frequency of anxiety, onychophagy and restless legs syndrome (RLS) in medical students and explore the relation among these conditions. Materials and methods: 315 medical students from the first to the fifth year from a private university where selected to participate. The instruments used for the study where: The Beck Anxiety Inventory, a Likert scale for onychophagy (nail biting), the Inventory of Epidemiological Studies for RLS (García - Borreguero) and the RLS Inventory (International RLS Group). Results: A frequency of anxiety (61.3%), onychophagy (52.63%) and RLS (9.29%) were found. Being male was a protective factor for anxiety (prevalence ratio (PR) = 0.74; p = 0.001, 95% CI = 0.63 to 0.89). There was an association between anxiety symptoms and RLS (PR = 2.52; p = 0.036, 95% CI = 1.06 - 6.00); and between anxious and onychophagy symptoms (PR = 1.47; p = 0.002, 95% CI = 1.15 - 1.87). Coexistence of onychophagy and RLS were associated with anxiety symptoms (PR = 5.37; p = 0.023, 95% CI = 1.26 - 22.82). There was no significant association between RLS and onychophagy. Conclusions: There is an association between anxiety and RLS, and between anxiety and onychophagy; but not between RLS and onychophagy. (AU)^ien.
