Conclusions Leisure time physical activity may reduce the risk of chronic LBP by 11%–16 % .
Background There are plausible mechanisms whereby leisure time physical activity may protect against  low back pain ( LBP )  but there have been no quality systematic review s and meta-analyses of the subject .
Objective This review aims to assess the effect of leisure time physical activity on non-specific LBP .
Low back pain incident episodes: a community-based study.
BACKGROUND CONTEXT The available evidence regarding low back pain ( LBP ) incident episodes is not consistent . Such knowledge can add information for the potential contribution of preventive programs . PURPOSE a ) To evaluate annual incident episodes of LBP among the general population . b ) To evaluate the contribution of demographic , lifestyle , and back pain history to LBP incident episodes . STUDY DESIGN A community-based longitudinal study . PATIENT SAMPLE A r and omized sample of individuals , free of LBP at a previous cross-sectional survey . OUTCOME MEASURES Low back pain during the past year . METHODS Subjects were followed up after 1 year . Baseline data included back pain history , perception of general health , physical activity , smoking , work satisfaction , and demographic characteristics . RESULTS Annual incident episodes of LBP were 18.4 % . Those who experienced LBP during the past year had a lower baseline perception of general health and were less involved in sporting activities than those free of pain . Those without history of LBP were more likely to be free of back pain after 1 year . CONCLUSIONS The annual incident episodes of LBP are relatively high and relate indirectly to baseline perception of general health and to level of sporting activities . Those without history of LBP are more likely to be free of back pain after 1 year . These results raise the potential of LBP preventive programs for adult population
