Objectives: To estimate the prevalence of chronic shoulder pain in the population of five Family Healthcare Units, to describe its semiological characteristics and the sociodemographic characteristics of this population. Secondarily, we intended to evaluate and quantify the association between chronic shoulder pain and functional disability, sociodemographic characteristics, and anxiety/depressive disorders. Type of study: Cross-sectional study. Location: Five Family Healthcare Units of Porto’s Metropolitan Area. Population: We obtained a sample of 1,718 patients between the ages of 18 and 64 from the population that visited the five Family Healthcare Units. Methods: We use a questionnaire to collect sociodemographic and chronic shoulder pain variables as well as two validated scales for the Portuguese population: Health Assessment Questionnaire-Disability Index and Hospital Anxiety and Depression Scale. We tested the association between chronic shoulder pain, functional disability, and anxiety/depression using the multinomial logistic regression model. Results: The estimated prevalence of chronic shoulder pain was 29.6%, confidence interval of 95% [27.4-31.8]; 57.8% patients had daily pain, 70.7% had moderate to severe pain, and 41.1% had little/no satisfaction with the treatment. It was found an association between pain degree or location and emotional status, gender, marital status, education, retirement, and retirement due to disability (p<0.001). In the chronic shoulder pain group, female gender, divorce, and widowhood, lower education, retirement due to disability, and anxiety/depression, were in a higher proportion. The higher odds ratio for chronic shoulder pain was found with a higher disability degree, anxiety, age, and lower education (nine years or less). Conclusions: Chronic shoulder pain prevalence was approximately seven times higher than initially expected. We found an association between chronic shoulder pain and the degree of disability and anxiety, which agrees with the reviewed literature. This study shows an urgent need to intervene effectively in the control of chronic shoulder pain.
