Long-term adolescent multi-site musculoskeletal pain is associated with psychological distress and anxiety

- Adolescents with long-term multi-site pain have elevated distress and anxiety.
- Multi-site musculoskeletal pain is more common among girls compared to boys.
- The results suggest a gender difference in the association between distress and pain.

ObjectiveAlthough several studies have shown that adolescent musculoskeletal pain is associated with psychological problems in a cross-sectional setting, the associations of long-term musculoskeletal pain with psychological distress and anxiety are not known.MethodsThe study included 1773 adolescents belonging to the Northern Finland Birth Cohort 1986. They received a postal questionnaire at the age of 16 years and a follow-up questionnaire two years later. The first inquiry contained questions about the sites of musculoskeletal pain; the second had the same pain questions, along with measures of distress and anxiety. Risk ratios (RR) were assessed by log-linear regression analysis.ResultsMulti-site musculoskeletal pain (in ≥ 2 body locations) at both 16 and 18 years was common, reported by 53% of girls and 30% of boys. Multi-site pain at both ages, compared to those with multi-site pain neither at 16 nor 18 years, was associated with psychological distress at the age of 18 among both girls (RR 1.8 95% CI 1.2-2.7) and boys (RR 3.5 95% CI 2.1-5.9). For anxiety, the corresponding relative risks were 1.5 (95% CI 1.0-2.2) and 1.8 (95% CI 1.4-2.3), respectively. For short-term multi-site pain (prevalent only at the age of 16 or 18), these relative risks were between 0.8 and 2.3.ConclusionsAdolescents with long-term multi-site pain have higher levels of distress and anxiety than those without or with only short-term multi-site pain. Associations were found in both genders, but the relationship between pain and distress was more pronounced among boys. The associations had modest effect strength.
