The rate of disability pension from back pain in Brazil was 29.96 per 100,000 beneficiaries. A higher rate was seen among males and older individuals. Rondônia showed the highest rate, four times as high as expected (RR= 4.05) followed by Bahia with a rate about twice as high as expected (RR=2.07). Commercial workers accounted for 96.9% of working days lost due to disability.
