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 .
Predictors for chronic neck and low back pain in office workers: a 1-year prospective cohort study.
OBJECTIVE All occupations expose workers to varied and unique conditions . The nature of work has been recognized as influencing the health of workers . Whether predictors for chronic neck and low back pain would be occupation-specific is unknown . This study aim ed to identify predictors for chronic neck and low back pain in a cohort of office workers . METHODS A prospect i ve study was carried out among 669 healthy office workers . At baseline , risk factors were assessed using a question naire and st and ardized physical examination . A symptomatic case was defined as an individual who reported pain greater than 30 mm on a 100-mm VAS , and chronic pain was defined as experiencing ongoing neck or low back pain for greater than 3 months over the past 6 months . Two regression models were built to analyze the risk factors for developing chronic neck and low back pain . RESULTS Of the sample , 17 and 27 % of office workers who reported a new onset of neck or low back pain developed chronicity , respectively . Predictors for chronic neck pain were high body mass index , frequent neck extension during the work day , high initial pain intensity , and high psychological job dem and s. The development of chronic low back pain was associated with history of low back pain and high initial pain intensity . CONCLUSIONS The findings suggest that predictors for chronic musculoskeletal pain in a sub population may be a subset of predictors identified in a general population or occupation specific . Successful management to prevent chronic musculoskeletal pain may also need to consider the patient 's occupation
