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

Abstract

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 16years 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 18years 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 18years, 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.
