Predicting who develops chronic low back pain in primary care: a prospective study
Abstract Objectives : To quantify the relative contribution of premorbid and episode specific factors in determining the long term persistence of disabling symptoms of low back pain . Design : Prospect i ve cohort study . Setting : Two general practice s in the south Manchester area . Participants : 180 patients , who previously participated in a cross sectional population survey , who consulted because of low back pain during the study period . They were followed at 1 week and 3 and 12 months after consultation . Main outcome measure : Persistent disabling low back pain in the 12 months after the consultation . Results : Disabling low back pain persisted in one third of participants after consultation and was more common with increasing age , among those with a history of low back pain , and in women .  Persistence of symptoms was associated with “ premorbid ” factors ( high levels of psychological distress ( odds ratio 3.3 ; 95 % confidence interval 1.5 to 7.2 ) , poor self rated health ( 3.6 ; 1.9 to 6.8 ) , low levels of physical activity ( 2.8 ; 1.4 to 5.6 ) , smoking ( 2.1 ; 1.0 to 4.3 ) , dissatisfaction with employment ( 2.4 ; 1.3 to 4.5 ) ) and factors related to the episode of low back pain ( duration of symptoms , pain radiating to the leg ( 2.6 ; 1.3 to 5.1 ) , widespread pain ( 6.4 ; 2.7 to 15 ) , and restriction in spinal mobility ) . A multivariate model based on six factors identified groups whose likelihood of persistent symptoms ranged from 6 % to 70 % . Conclusions : The presence of persistent low back pain is determined not only by clinical factors associated with pain but also by the premorbid
