[BDSP. Notice produite par INIST gkDbXR0x. Diffusion soumise à autorisation]. Study objective-To explore the previously stated hypothesis that risk factors for atherothrombotic disease are associated with back pain. Design-Prospective (mean of four years of follow up) and retrospective analyses using two main outcome measures : (a) short (<= 7 days) and long (>7 days) spells of sickness absence because of back pain reported separately in men and women ; (b) consistency of effect across the resulting four duration of spell and sex cells. Setting-14 civil service departments in London Participants-3506 male and 1380 female white office-based civil servants, aged 35-55 years at baseline. Main results-In age adjusted models, low apo AI was associated with back pain across all four duration-sex cells and smoking was associated across three cells. Six factors were associated with back pain in two cells : low exercise and high BMI, waist-hip ratio, triglycerides, insulin and Lp (a). On full adjustment (for age, BMI, employment grade and back pain at baseline), each of these factors retained a statistically significant effect in at least one duration-sex cell. Triglycerides were associated with short and long spells of sickness absence because of back pain in men in fully adjusted models with rate ratios (95% confidence intervals) of 1.53 (1.1,2.1) and 1.75 (1.0,3.2) respectively.
