The findings come from a survey of 8,000 adults by back specialist Dynaspine.
It found the top four factors for causing back pain are: long hours sitting behind desks (62%), bad posture while at work (42%), heavy lifting (26%) and stress (19%).
It supports data that already finds back pain is the second largest cause of absence, at a cost of £7 billion per year.
According to Dynaspine though, only 6% of back pain sufferers actually see a chiropractor to treat the source of the problem.
It also finds 15% of employees say they have never had any advice from employers on how to look after their backs.
