I heard a report that people who work at night are more likely to see a doctor for back pain than day-time workers. Is there any particular reason for this? I work at night but I've never had back pain while on the job.

A simple and common sense reason may be accessibility. Workers who are free during the day can get to the doctor's without taking time off from work to go. It is possible that there are fewer workers available at night to help lift, carry, or haul heavy objects.

There aren't any studies on this factor in looking at workers with low back pain. The answer to your question may remain a mystery until more research is done in this area.
