BMI at Age 20 Influences Future Risk of Low Back Pain

A nationwide, cross-sectional study of men aged 30–50 years (n=1385) examined the relationship between weight and back pain over time.

Using a nationwide survey and military records they assessed the height and weight of men at the ages of 20, 30, 40 and 50 years and examined the clinically defined outcome measures of chronic low-back syndrome and sciatica. 

Data showed being overweight or obese in early adulthood (and during the life course) increases the risk of radiating but not non-specific LBP among men.  Baseline BMI (at age 20 years) predicted radiating LBP in adulthood, with the prevalence ratio (PR) being 1.26 (95% CI 1.08 to 1.46) for one SD (3.0 kg/m2) increase in BMI. The development of obesity during follow-up increased the risk of radiating LBP (PR=1.91, 95% CI 1.03 to 3.53).
