Background: According to the Global Burden Disease, in early childhood (up to 14 years of age) the rate of years lived with disability is 3%, during adolescence and adulthood this rate increases to 16% and reaches 21% in old age. Recent evidence also indicates that the experience of persistent musculoskeletal pain during adolescence is a risk factor for chronic pain in adulthood. However, it does not have larger studies prevalence of disabling musculoskeletal pain in children and adolescents in low and middle-income countries.

Purpose: The aim of this study is to determine the prevalence of disabling musculoskeletal pain in children and adolescents in Sao Paulo state.

Methods: This is a cross-sectional study approved by the Research Ethics Committee of the Universidade Cidade de São Paulo (UNICID) (CAAE: 18752219.0000.0064). Data was collected in public and private schools in the cities of Sao Paulo, Itu and Salto. The sample was constituted of 549 children and adolescents aged 8 to 18 years, able to read and write in Brazilian-Portuguese and their respective parents and/or guardians. Only children and adolescents whose parents and/or guardians authorize participation through the Consent Form was included in the study.

Results: The sample consists of 326 boys (59.4%) and 223 girls (40.6%), the average age of 11.35 years (SD 6.36 years), 287 students (52%) reported not performing physical activity, 60 students had some type of medical diagnosis, of which 13 reported a diagnosis of neurological disease. The average body weight and height was 45.72 kg (SD 14.78 kg) and 151 cm (SD 14.68 cm), respectively.
Of the total sample, 64.12% reporting some musculoskeletal pain, with the average pain on the numerical pain scale (NRS) being 4.23 points (SD 2.56). The most affected body segments was lower limbs (42.05%) follow by back (38.35%), neck (19.32%) and upper limbs (12.78%). Disabling musculoskeletal pain rate was reported in 30% of children and adolescents, with 20.74% of students reported missing school due to pain, 27.27% reported that pain interfered with normal activities in the last month and 28.41% reported that pain interfered with recreational physical activities in the last month.

Conclusion(s): Disabling musculoskeletal pain was high among children and adolescents in Sao Paulo state. The disabling associated with musculoskeletal pain was school absenteeism, interference in normal and recreational activities.

Implications: Understanding the prevalence rates of disabling musculoskeletal pain allows us understand the current scenario in the country, since population changes are faster in low and middle-income countries. After understand the overall scenario is possible create strategies to reduces the burden of disabling musculoskeletal pain in children and adolescents.
