Does leisure time physical activity protect against low back pain? Systematic review and meta-analysis of 36 prospective cohort studies

Abstract Background Although working activities are associated with several pregnancy outcomes, there is scarce information regarding the association between working activities and low back pain (LBP) during pregnancy. This study aimed to investigate whether leisure-time and work-related physical activities during pregnancy are associated with LBP. Methods Data from the 2015 Pelotas Birth Cohort study were used. Demographic, socioeconomic, gestational, leisure-time (prior to and during pregnancy) and work-related (days of work, hours of work, standing and heavy lifting) physical activity data were collected at birth. LPB was assessed in the 12-month follow-up period. Results Leisure-time physical activity either prior to and during pregnancy was not associated with LBP. Working during pregnancy, days of work and standing position at work were not associated with self-reported LBP during pregnancy. However, working more than 8 h per day and always lifting heavy objects at work increased the odds ratio for LBP (OR 1.30 95%CI: 1.04; 1.63; and OR: 1.39 95%CI 1.08; 1.81, respectively). In addition, women who had lifted heavy objects often/always, reported an increase in pain intensity. Conclusion Working during pregnancy and days worked per week were not related to experiencing LBP. However, women who worked more than 8 h per day, as well as women who lifted heavy objects at work on a regular basis, were more likely to experience pregnancy-related LBP.

Prospective Cohort Studies

Background Many cohort studies within the past few decades have shown the protective effect of leisure-time physical activity on cardiovascular mortality. To summarise the evidence from prospective cohort studies on the relationship between the amount of leisure-time physical activity and the risk of cardiovascular mortality, a dose–response meta-analysis was conducted in this study. Methods and results Electronic databases, including PubMed and Embase databases, Scopus and Cochrane Library, were systemically retrieved by two investigators from inception to 14 June 2018 for related studies. The maximum adjusted hazard ratios (HRs) and 95% confidence intervals (CIs) were extracted, and a dose–response analysis was conducted using the restricted cubic splines. Finally, a total of 44 studies comprising 1,584,181 participants was enrolled into this meta-analysis. The HRs of cardiovascular mortality for moderate and high leisure-time physical activity were 0.77 (95% CI 0.74–0.81) and 0.73 (95% CI 0.69–0.77), respectively. Among these 44 studies, 19 were eligible for the dose–response meta-analysis, which suggested a linear negative correlation of leisure-time physical activity with cardiovascular mortality, regardless of age, gender and the presence of underlying cardiovascular disease or not. Conclusions Leisure-time physical activity shows a linear negative correlation with the risk of cardiovascular mortality regardless of age, gender and the presence of cardiovascular disease or not. However, the cardiovascular benefits of leisure-time physical activity is decreased for those aged over 65 years or those with a history of cardiovascular disease. Moreover, leisure-time physical activity displays more cardiovascular benefits to people followed up for over 10 years than to those followed up for less than 10 years. Besides, high-intensity leisure-time physical activity has more obvious cardiovascular benefits than those of moderate-intensity leisure-time physical activity.
