The variables associated with pain in the low back region were: female gender (PR=1.70), daily TV use for more than 3hours (PR=1.17), use of laptop computer (PR=1.40), use of the cell phone in the supine position (PR=1.23), use of the cell phone in semi-supine position (PR=1.49), daily cell phone use for more than 3hours (PR=1.36), use of tablet (PR=1.67), daily tablet use for more than above 3hours (PR=1.46), and clinically important mental health problems (PR=2.62).
