Healthy lifestyle behaviour and risk of long-duration troublesome neck pain among men and women with occasional neck pain : results from the Stockholm public health cohort

OBJECTIVES: The effect of a healthy lifestyle on the prognosis of neck pain is unknown. This study aimed to investigate if a healthy lifestyle behaviour influences the risk of long-duration troublesome neck pain among men and women with occasional neck pain. DESIGN: Longitudinal cohort study. SETTINGS: General population, and a subsample of the working population, in Stockholm County, Sweden. PARTICIPANTS: This study involved 5342 men and 7298 women, age 18 to 84, from the Stockholm Public Health Cohort, reporting occasional neck pain at baseline in 2006. MEASURES: Baseline information about leisure physical activity, smoking, alcohol consumption and consumption of fruits and vegetables were dichotomised into recommendations for healthy/not healthy behaviour. The exposure, a healthy lifestyle behaviour, was categorised into four levels according to the number of healthy behaviours (HB) met. Generalised linear models were applied to assess the exposure on the outcome long-duration troublesome neck pain (activity-limiting neck pain ≥2 days/week during the past 6 months), at follow-up in 2010. RESULTS: The adjusted risk of long-duration troublesome neck pain decreased with increasing adherence to a healthy lifestyle behaviour among both men and women (trend test: p<0.05). Compared with the reference category, none or one HB, the risk decreased by 24% (risk ratio 0.76, 95% CI 0.58 to 0.98) among men and by 34% (0.66, 0.54 to 0.81) among women, with three or four HBs. The same comparison showed an absolute reduction of the outcome by 3% in men (risk difference -0.03, 95% CI -0.05 to -0.01) and 5% in women (-0.05,-0.08 to -0.03). Similar results were found in the working population subsample. CONCLUSION: Adhering to a healthy lifestyle behaviour decreased the risk of long-duration troublesome neck pain among men and women with occasional neck pain. The results add to previous research and supports the importance of promoting a healthy lifestyle behaviour
