Background. In population studies, body mass index (BMI) is generally calculated from self-reported body weight and height. The self-report of these anthropometrics is known to be biased, resulting in a misclassification of BMI status. The aim of our study is to evaluate the accuracy of self-reported weight, height and waist circumference among...

The objective of this prospective cohort study was to evaluate if peak or cumulative musculoskeletal discomfort may predict future low-back, neck or shoulder pain among symptom-free workers. At baseline, discomfort per body region was rated on a 10-point scale six times during a working day. Questionnaires on pain were sent out three times...

Background. Missing data is a challenging problem in many prognostic studies. Multiple imputation (MI) accounts for imputation uncertainty that allows for adequate statistical testing. We developed and tested a methodology combining MI with bootstrapping techniques for studying prognostic variable selection. Method. In our prospective cohort...

Aims: To investigate the longitudinal relation between physical capacity (isokinetic lifting strength, static endurance of the back, neck, and shoulder muscles, and mobility of the spine) and low back, neck, and shoulder pain. Methods: In this prospective cohort study, 1789 Dutch workers participated. At baseline, isokinetic lifting strength,...

A controlled trial was performed in a occupational healthcare setting to determine the effectiveness of graded activity as part of a multistage RTW programme. Workers (112) absent from work for more than eight weeks due to low back pain, were randomised to either graded activity (n = 55) or usual care (n = 57). The graded activity, a physical...
