Results of binary logistic regression models estimating the association between categories of sitting time and high intensity of low back pain (>5 on a scale 0–9) among blue-collar workers.

Table footnotes: Total sitting time: low ≤6.4h, moderate = 6.5–8.3h and high >8.3h; Occupational sitting: low ≤2.0h, moderate = 2.1–3.7h and high>3.7h; leisure-time sitting: low≤3.9h, moderate = 4.0–5.4h and high>5.4h, n = number of workers, OR = odds ratio, 95%CI = 95% confidence interval, a Reference b Crude analysis, c Adjusted for age, gender, smoking and BMI (individual factors, step 1). d Step 1 + seniority, influence at work and occupational lifting/carrying time (occupational factors, step 2). e Step 2 + sitting time during opposite domain depending on the modelled variable (step 3) Results of binary logistic regression models estimating the association between categories of sitting time and high intensity of low back pain (>5 on a scale 0–9) among blue-collar workers.
