Binary logistic regression analyses of the association between objectively measured sitting (hours/day) and high LBP intensity (>5 on scale 0–9) among blue-collar workers.

Table footnotes:
n = number of workers, OR = odds ratio, 95%CI = 95% confidence interval,
a Crude model,
b Adjusted for age, gender, smoking and BMI (Individual factors, Step 1).
c Step 1+seniority, influence at work, and occupational lifting/carrying time (occupational factors, step 2).
d Step 2+sitting time in the opposite domain (Step 3).
