title: Do physical activity level and body mass index predict recovery from persistent neck pain in men and women of working age? A population-based cohort study.
abstract: OBJECTIVE
  The study sought to examine the gender-specific effects of physical activity level and body mass index on recovery from persistent neck pain (PNP) among citizens of working age in Stockholm, Sweden.
  
  
  METHODS
  A population-based cohort of 1,730 subjects (18-65) with PNP answered surveys in 2002 and 2007. Prognostic factors were self-reported body mass index (BMI) and physical activity level (PAL) at baseline. Analyses were performed with odds ratios (OR) with corresponding 95 % confidence intervals (95 % CI).
  
  
  RESULTS
  Women reporting higher physical activity level had higher odds of recovering from PNP than women with sedentary leisure time (OR of 1.5, 95 % CI 1.0-2.4), but no associations were found in men. No associations were found between BMI and recovery from PNP in any analyses.
  
  
  CONCLUSIONS
  Physical activity seems to be associated with recovery from PNP in women and should therefore be encouraged. Future studies should continue investigating physical activity and lifestyle factors in relation to recovery from persistent neck pain, since these modifiable factors may be considered in interventions.
