According to the World Health Organization's website, which age group experiences the highest prevalence of Low Back Pain?

Question

BlackTom AI · Accepted Answer

Prevalence of low back pain increases with age and reaches its highest point in older adults, so the peak group is older adults aged 70–75 years.

1) Relevant knowledge points and concepts
- Low back pain (LBP) is strongly associated with age-related degenerative changes (intervertebral disc degeneration, facet joint osteoarthritis), reduced muscle mass/strength (sarcopenia), increased comorbidity burden, and cumulative exposure to mechanical stress.  
- WHO reports and Global Burden of Disease estimates track prevalence and years lived with disability (YLDs) by age; these data consistently show increasing prevalence through adulthood with a peak in the oldest adult groups.

2) Step-by-step reasoning
- Younger populations (children and adolescents) have a much lower frequency of chronic LBP because degenerative spine changes and long-term cumulative mechanical wear are minimal.  
- Middle-aged adults (50–55 years) show higher rates than adolescents but have had less lifetime degeneration and fewer age-related comorbidities than older adults.  
- Older middle age (60–65 years) shows further increase, but many age-related pathologies continue to progress beyond this decade.  
- By the seventh decade (around 70–75 years), cumulative degenerative changes, reduced tissue resilience, greater comorbidity, and functional decline culminate in the highest observed prevalence of LBP.

3) Calculations/intermediate steps
- No numerical calculation is needed; the conclusion follows from age-related risk accumulation and WHO prevalence summaries indicating the highest prevalence in the oldest adult brackets.

4) Why the correct answer is correct
- WHO data identify the oldest age brackets as having the highest prevalence; mechanistic and epidemiological evidence explain why prevalence peaks around 70–75 years.

5) Why other options are incorrect
- Adults 50–55 and 60–65: show elevated but not peak prevalence compared with the 70–75 group.  
- Children and adolescents: have the lowest prevalence due to lack of degenerative changes and lower cumulative risk.

Conclusion: This supports and confirms the provided correct answer: Older adults aged 70-75 years.
