[Abstract] Objective. Axial osteoarthritis (OA) is a common cause of back and neck pain, however, few studies have examined its prevalence. The aim was to estimate the prevalence and the characteristics of symptomatic axial OA in Spain. Methods. EPISER2016 is a cross-sectional multicenter population-based study of people aged 40 years or older. Subjects were randomly selected using multistage stratified cluster sampling. Participants were contacted by telephone to complete rheumatic disease screening questionnaires. Two phenotypes were analyzed, patients with Non-exclusive axial OA (NEA-OA) and Exclusive axial OA (EA-OA). To calculate the prevalence and its 95% confidence interval (CI), the sample design was considered and weighting was calculated according to age, sex and geographic origin. Results. Prevalence of NEA-OA by clinical or clinical-radiographic criteria was 19.17% (95% CI: 17.82–20.59). The frequency of NEA-OA increased with age (being 3.6 times more likely in patients aged 80 s or more than in those between 40 and 49 years) and body mass index. It was significantly more frequent in women, as well as in the center of Spain. It was less frequent in those with a higher level of education. Lumbar OA was more frequent than cervical OA. This difference grew with increasing age and was not associated with gender. It was also greater in overweight and obese subjects. Conclusions. This is the first study on the prevalence of axial OA phenotypes in Europe describing the associated socio-demographic, anthropometric, and lifestyle variables.

[Resumen] Introducción. La Sociedad Española de Reumatología elaboró en el año 2000 el estudio EPISER2000 para conocer la prevalencia de la artrosis y otras enfermedades reumáticas en España. Los cambios sociodemográficos y en los hábitos de vida ocurridos en los últimos años en España justifican actualizar los datos de las enfermedades reumáticas (EPISER2016). Objetivo. Estimar la prevalencia de artrosis sintomática de columna cervical, columna lumbar, cadera, rodilla y mano, en población adulta en España. Material y métodos. Estudio transversal de base poblacional. Se realizó un muestreo aleatorizado polietápico estratificado y por conglomerados. Los participantes fueron contactados por teléfono para cumplimentar un cuestionario de cribado de artrosis. El reumatólogo confirmaba o descartaba el diagnóstico. Se utilizaron los criterios-clínicos-ACR para diagnosticar artrosis de manos y los criterios clínico-radiológicos-ACR para diagnosticar la artrosis de rodilla y cadera. Resultados. La prevalencia de artrosis en España en una o más de las localizaciones estudiadas fue de 29,35%. La prevalencia de artrosis-cervical fue del 10,10% y de artrosis-lumbar del 15,52%. Ambas son más frecuentes en mujeres y a mayor edad, así como en personas con niveles de estudios bajos y obesidad. La prevalencia de artrosis de cadera fue del 5,13% y la de artrosis de rodilla del 13,83%; estas se asocian con el sexo femenino, sobrepeso y obesidad, menor frecuencia en nivel de estudios alto y con la edad. La prevalencia de la artrosis de mano fue del 7,73%. Es más frecuente en mujeres, obesas, con bajo nivel de estudios y mayor edad. Conclusiones. El estudio EPISER2016 es el primero que analiza la prevalencia de artrosis sintomática en 5 localizaciones (columna cervical, lumbar, rodilla, cadera y manos) en España. La artrosis de la columna lumbar es la más prevalente., [Abstract] Introduction. The Spanish Society of Rheumatology carried out the EPISER2000 study in 2000 to determine the prevalence of osteoarthritis and other rheumatic diseases in the Spanish population. Recent sociodemographic changes and lifestyle habits in Spain justified updating the epidemiological data on osteoarthritis and other rheumatic diseases (EPISER2016-study). Objective. To estimate the prevalence of symptomatic osteoarthritis of the cervical spine, lumbar spine, hip, knee and hand in the adult population in Spain. Material and methods. Cross-sectional population-based study. A multistage and stratified random cluster sampling was carried out. The participants were contacted by telephone to complete an osteoarthritis screening questionnaire. A rheumatologist confirmed or discarded the diagnosis. The ACR-clinical-criteria were used to diagnose hand-osteoarthritis and the ACR-clinical-radiological criteria to diagnose knee- and hip-osteoarthritis. To estimate the prevalence and its 95% confidence interval, weights were calculated according to the probability of selection in each of the sampling stages. Results. The prevalence of osteoarthritis in Spain in one or more of the locations studied was 29.35%. The prevalence of cervical-osteoarthritis was 10.10% and of lumbar-osteoarthritis 15.52%. Both are more frequent in women and at older ages, as well as in people with low levels of education and obesity. The prevalence of hip-osteoarthritis was 5.13%, that of knee-osteoarthritis 13.83%, these are associated with female sex, overweight and obesity. The prevalence of hand osteoarthritis was 7.73%. It is more frequent in women, who are obese, with a low educational level and who are older. Conclusion. The EPISER2016 study is the first to analyse the prevalence of symptomatic osteoarthritis in 5 locations (cervical, lumbar, knee, hip and hands) in Spain. Lumbar spine osteoarthritis is the most prevalent.
