abstract = {Purpose To estimate the prevalence of diagnosed and undiagnosed chronic low back pain (CLBP-D and CLBP-UD, respec tively) in the general adult population in Spain and to compare the characteristics of these two groups with subjects without 
CLBP symptoms (No-CLBP). To establish CLBP-D patient sub-groups according to their self-perceived health status, mental health, level of pain and the impact of their pain on daily activities.
Methods Data were obtained from the National Health Survey of Spain 2017 with a sample of 23,089 adults. Three groups were defned: CLBP-D, CLBP-UD and No-CLBP. In the CLBP-D group, a cluster analysis was performed to identify sub groups. A multinomial regression model was constructed to determine the factors associated with each of the sub-groups identifed.
Results The prevalence of CLBP-D was 22% (95% CI 21.5–22.5) and that of CLBP-UD was 1.4% (95% CI 1.2–1.5). CLBP-D was more common in middle-aged females with a low educational level. They have a worse perceived health status, report more comorbidities, have worse mental health and more limitations in comparison with the populations without CLBP and with CLBP-UD. Three sub-groups of CLBP-D subjects were identifed. Women and older subjects with a lower educational 
level, more occupational stress, less social support and with more physical limitations were the most likely subjects to be included in the group worst-afected.
Conclusions There is a high prevalence of CLBP among the adult population in Spain. Occupational stress and a lack of social support are common factors among subjects’ worst-afected of CLBP-D and identifying the subjects with these risks 
is therefore a recommended strategy for improving the healthcare provided to CLBP patients.},
