Unhealthy eating habits and lack of proper nutrition knowledge cause non-communicable diseases and affect adolescents. It is in adolescence that eating habits are formed that persist till adulthood. Lifestyle interventions are needed to curb NCDs in adolescents. This paper reports the findings of a study that aimed to validate a lifestyle intervention program and its effect on food intake, physical activity, and nutrition knowledge. It was a clustered randomized control trial study conducted in four (4) junior secondary schools. There were 46 participants, 21 in the control and 25 in the intervention arm, who were blindly assigned to each arm by a statistician. Information and skills on nutrition were imparted using the Information, Motivation, and Behavioral Skills model. The program was implemented for eight (8) weeks hourly after school. A questionnaire was used to collect data pre- and post-intervention. Number, proportion, percentage, and independent t-test (mean and SD or median and IQR, p-value) were calculated using numerical and categorical data. The findings showed that the lifestyle intervention was valid, and there was a slight decrease in the intake of sweets among participants in both trial arms (p = 0.066). There was no significant difference in terms of food intake. Only a small number of participants still ate a few fruits, and there was no change in vegetable intake in both trial arms (p = 0.641). There was no change in the intake of fried foods in both trail arms (p = 0.402). Regarding nutrition knowledge, there was a slight significant difference of p = 0.079 between the trial arms. Though the effect of the lifestyle intervention program was not statistically significant, the results are promising, especially if the duration could be increased to a longer period and a larger sample size included.展开更多

A systematic search was performed in MEDLINE, CINAHL, Scopus, Web of Science, Cochrane Database of Systematic Reviews,and Physiotherapy Evidence Database(PEDro), including reference lists of relevant reviews, covering studies published between January 1,2010 and May 20, 2024. Eligible studies were systematic reviews of randomized controlled trials and observational studies, with or without meta-analyses. The primary outcome for secondary prevention was LBP recurrence, while for management, primary outcomes included pain intensity and disability, with adverse events as secondary outcomes. Data were extracted across immediate, short-term, intermediate, and longterm follow-up periods. The Grading of Recommendations Assessment, Development, and Evaluation(GRADE) framework was used to assess the certainty of evidence, and the Assessment of Multiple Systematic Reviews tool(AMSTAR) tool was applied by 2 independent reviewers(JC, QL, and/or DXMW) to evaluate the quality of the included reviews. The study was prospectively registered on the Open Science Framework(OSF).Results: A total of 70 systematic reviews were included, 43 with meta-analyses, 7 with network meta-analyses, and 20 without meta-analyses.Six(out of 10) reviews with meta-analyses for secondary prevention indicated a small benefit from general exercises and leisure-time PA(low-to-moderate certainty). For LBP management, 35(out of 36) reviews reported that exercise therapies such as Pilates, motor control,mixed exercise, Tai Chi, water-based exercises, and yoga showed small beneficial effects on pain and disability compared to minimal intervention mainly in the short-term(low-to-moderate certainty). Seven network meta-analyses favored motor control and Pilates over other forms of exercise to reduce pain(low certainty). Adverse events were reported in less than 31% of the reviews, predominantly involving postexercise soreness and temporary increases in pain, mainly in yoga-related studies. Adverse events were considered minor, and no serious adverse events were reported.Conclusion: There is low-to-moderate certainty that exercise therapy and leisure-time PA are beneficial for improving pain and preventing the recurrence of LBP. However, evidence on the potential harms of these interventions is limited, and adverse events related to exercise and PA remain under-investigated.展开更多

文摘Background It remains unclear whether sleep duration and physical activity(PA)trajectories in middle-aged and older adults are associated with different risks of cardiovascular diseases(CVDs).This study aimed to explore the trajectories of total sleep duration and PA among middle-aged and older Chinese adults and their impact on CVD risk.Methods This study was based on the China Health and Retirement Longitudinal Study.12009 adults aged 45 years and older from five waves were included.CVD events were measured by self-reports of heart disease and stroke.We first used groupbased trajectory modeling to identify total sleep duration and PA trajectories from 2011 to 2020,and then employed logistic regression models to analyze their risk for CVD.Results We identified three sleep duration and PA trajectories.The risk of heart disease increased by 33%(OR=1.31,95%CI:1.12-1.53)for the short sleep duration trajectory(vs.moderate sleep duration trajectory),by 40%(OR=1.40,95%CI:1.06-1.84)for the high decreasing PA trajectory,and by 20%(OR=1.20,95%CI:1.01-1.42)for the low stable PA trajectory(vs.high stable PA trajectory),respectively.Similar results for stroke and CVD as the outcomes were also observed,but the higher risk of stroke in the high decreasing PA trajectory group was not statistically significant.The joint effects of sleep and PA showed lower risks of heart disease and stroke in trajectories with moderate or long sleep duration and high stable PA compared with short sleep duration and a low stable PA trajectory.Conclusions Short total sleep duration,high decreasing PA,and low stable PA trajectories could increase the risk of CVDs among middle-aged and older adults.Long-term moderate to long total sleep durations and high stable PA trajectories might be optimal for preventing CVDs.

文摘Today, most people know that physical activity(PA) is beneficial for their health ^(1,2)and aspire to engage in regular PA.^(3,4)However, despite their awareness of the importance of PA, it is evident that the transition from intention to action is challenging-a situation that has important public health implications. According to the World Health Organization,^(5)1 person dies every 6 s worldwide from causes related to physical inactivity, which underscores the urgency of addressing this situation.
文摘There is no way around it.Regular physical activity(PA)and a high-quality diet are essential to promoting good health and prolonging life in middle-aged and older adults.In the November 2024 Issue of the Journal of Sport and Health Science,Ding et al.
文摘In the new released article of the Journal of Sport and Health Science,Zaccardi et al.1 provide compelling evidence that engaging in higher volumes and intensities of physical activity(PA)increases life expectancy in older men and women enrolled in the UK Biobank study.The study included 30,820 men and 40,953 women with median ages of 63.1 years and 61.9 years,respectively.Study participants wore accelerometers to track their time and intensity of PA for 7 days at baseline.

文摘Background There is a lack of research examining the interplay between objectively measured physical activity volume and intensity with life expectancy.The purpose of the study was to investigate the interplay between objectively measured PA volume and intensity profiles with modeled life expectancy in women and men within the UK Biobank cohort study and interpret findings in relation to brisk walking.Methods Individuals from UK Biobank with wrist-worn accelerometer data were included.The average acceleration and intensity gradient were extracted to describe the physical activity volume and intensity profile.Mortality data were obtained from national registries.Adjusted life expectancies were estimated using parametric flexible survival models.Results 40,953(57.1%)women(median age=61.9 years)and 30,820(42.9%)men(63.1 years)were included.Over a median follow-up of 6.9 years,there were 1719(2.4%)deaths(733 in women;986 in men).At 60 years,life expectancy was progressively longer for higher physical activity volume and intensity profiles,reaching 95.6 years in women and 94.5 years in men at the 90th centile for both volume and intensity,corresponding to 3.4 additional years(95%confidence interval(95%CI):2.4-4.4)in women and 4.6 additional years(95%CI:3.6-5.6)in men compared to those at the 10th centiles.An additional 10-min or 30-min daily brisk walk was associated with 0.9(95%CI:0.5-1.3)and 1.4 years(95%CI:0.9-1.9)longer life expectancy,respectively,in inactive women;and 1.4 years(95%CI:1.0-1.8)and 2.5(95%CI:1.9-3.1)in inactive men.Conclusion Higher physical activity volumes were associated with longer life expectancy,with a higher physical activity intensity profile further adding to a longer life.Adding as little as a 10-min brisk walk to daily activity patterns may result in a meaningful benefit to life expectancy.

文摘Diabetes mellitus(DM)has become one of the most serious and common chronic diseases around the world,leading to various complications and a reduction in life expectancy.Increased sedentary behavior(SB)and decreased physical activity(PA)are important contributors to the rising prevalence of DM.This article reviews the research progress on the pathogenesis of DM,the effects of SB and PA on the risk of DM,aiming to explore the influence of different PA intensities,amounts,frequencies,durations and types on the incidence of DM.Research has shown that blood glucose levels tend to increase with the prolongation of SB.Within a certain range,PA intensity and PA amount are negatively correlated with the risk of DM;Performing PA for more than 3 days per week maintains normal glucose tolerance and lower blood pressure;Engaging in 150–300 min of moderate intensity exercise or 75–150 min of high-intensity exercise per week reduces the risk of DM;PA during leisure time reduces the risk of DM,while PA during work increases the risk of DM;Both aerobic training and resistance training reduce the risk of DM,and the combination of the two training methods produces better benefits;Various types of exercises,such as cycling,soccer,aerobics,yoga,tai chi,all reduce the risk of DM.In summary,prolonged SB increases the risk of DM,while appropriate PA reduces the risk of DM.As the intensity,amount,and frequency of PA increase,the effect of reducing DM risk becomes more significant.Different exercise methods have different effects on reducing DM risk.
文摘Device-based measurements are recommended to improve population-based physical activity(PA)surveillance.1,2However,implementation remains challenging due to lack of consensus on analytical methods,and the most widely used“generic”(absolute intensity)cut-point approach has limited generalisability to population-level free-living data.Further,current methods generally fail to account for differences in people's physical capacity.

文摘Background:University students face significant challenges inmaintaining healthy physical activity(PA)and dietary habits,and they often fall short of global health recommendations.Psychological factors such as social physique anxiety,body image concerns,and self-objectification may act as barriers to PA engagement,influencing both mental and physical health.The present study constructed a structural equation model(SEM)to examine the relationship between body image-related psychological factors and resistance to PA in university students from southern Spain.Methods:A cross-sectional and correlational study was conducted with 519 university students(74%females,26%males;Mean age=21.14±3.26 years)from universities in Granada and Malaga(Spain).Data were collected between May and October 2024 via online questionnaires that assessed PA engagement,Mediterranean diet adherence,eating disorder symptoms,body image-related psychological factors(social physique anxiety,appearance control beliefs,body surveillance,body shame,and self-esteem),and sociodemographic characteristics.SEM was performed to analyze relationships and sex-based differences.Results:Social physique anxietywas positively associated with body shame,body surveillance,and eating disorders,and negatively associated with self-esteem,PA engagement,and appearance control beliefs(all p<0.001).Appearance control beliefs were positively related to self-esteem,body surveillance,and PA(all p<0.05).Body surveillance was negatively linked to PA and positively linked to body shame.Mediterranean diet adherence and eating disorders were positively associated with PA(all p<0.001).Sex-based differences were observed in the model.Conclusion:Body image-related psychological factors may act as barriers to PA among university students.Interventions should integrate mental health promotion and consider sex differences.
文摘BACKGROUNDAs the population of colorectal cancer(CRC)survivors continues to grow,thedemand for effective,evidence-based post-treatment strategies becomes increasinglyurgent.Despite robust evidence linking lifestyle factors to canceroutcomes,there remains no established consensus on the optimal nutritional andphysical activity(PA)guidelines for disease-free CRC survivors.AIMTo demonstrate that structured lifestyle interventions,specifically tailored dietaryand PA programs,can significantly improve behavioral targets as well as diseasefreeand overall survival(OS).METHODSWe designed a 2×2 factorial phase II randomized controlled trial to compare the effects of dietary and PA interventions with standard care.RESULTSA total of 300 CRC survivors in complete remission will be recruited from oncology centers in Misurata and Zliten(Libya)and the Habib Bourguiba University Hospital(Tunisia).Participants will be randomized into four groups:Combined intervention,diet-only,PA-only,or usual care.They will be followed for 24 months,with outcomesincluding disease-free survival,OS,and quality of life.Ethical approval has been obtained(Sfax ID:61/24;Misurata ID:04/2023),and the trial is registered at ClinicalTrials.gov(NCT06194786).CONCLUSIONThis study will provide crucial region-specific evidence on the feasibility and effectiveness of lifestyle interventionsin CRC survivorship care.By evaluating the role of a high-fiber,low-red meat diet and structured PA,we aim todemonstrate the potential of these behaviors to improve survival outcomes and support their integration intofuture clinical practice guidelines.

文摘BACKGROUND Physical activity(PA)is a key contributor to the neurocognitive and psychological development of children and adolescents.With the rapid integration of digital technologies in educational and recreational contexts,technology-enhanced PA(TEPA)interventions have emerged as promising tools for promoting mental and cognitive health.However,the effectiveness of various TEPA modalities—such as virtual reality(VR),mobile applications,and biofeedback systems—remains unclear.Prior findings are fragmented across systematic reviews with inconsistent methodologies.This umbrella review was conducted to synthesize current evidence and evaluate whether specific TEPA modalities yield differential benefits.We hypothesized that TEPA interventions with immersive and selfregulatory features provide greater enhancements in executive function(EF),cognitive function(CF),and mental health(MH)than passive or minimally interactive formats.AIM To determine the effects of TEPA interventions and modality-specific characteristics on EF,CF,and MH outcomes in children and adolescents.METHODS An umbrella review of systematic reviews and meta-analyses was conducted in accordance with Preferred Reporting Items for Systematic Reviews and Meta-Analyses 2020 guidelines.Five databases(PubMed,Web of Science,EMBASE,EBSCOhost,and Cochrane Library)were searched up to March 2025.Eligible reviews included participants aged≤18 years,assessed TEPA interventions,and reported EF,CF,or MH outcomes.Methodological quality was assessed using A Measurement Tool to Assess Systematic Reviews 2.Data synthesis was stratified by intervention modality,and heterogeneity was evaluated using the I^(2)statistic.RESULTS A total of 11 systematic reviews and meta-analyses were included.Interventions using VR(2/2),game-based formats(2/2),biofeedback(2/2),and multicomponent programs(1/1)showed consistent evidence of improvements in EF and MH(e.g.,EF:6.92±3.86 vs 3.61±1.67,P<0.001).App-based interventions(3/3)demonstrated mixed or modest effects,while augmented reality-based formats showed limited efficacy.MH outcomes were most frequently improved(9/11 reviews),followed by EF(6/11 reviews)and CF(5/11 reviews).Heterogeneity ranged from moderate to high(I^(2)=42%-78%)across modalities.CONCLUSION TEPA significantly improves MH and selectively enhances executive and CF in youth.Immersive,interactive,and biofeedback-driven modalities are particularly effective.
文摘Cancer prevention via regular physical activity has been studied across the world.This minireview aimed to present the latest updates in research in the context of the role of physical activity in the cancer prevention.The various mechanisms at the molecular level were studied in depth.The essential processes at play involving hormonal balance,weight reduction,adiposity,inflammation,immunity,sunlight exposure and vitamin D levels and insulin resistance were critically analyzed here.The dose response of exercise with respect to cancer prevention was appraised.Strong evidence supports an inverse relationship between physical activity and cancer risk,particularly for breast,liver,lung and colorectal cancers.There is limited evidence for hematologic,head and neck,ovarian,pancreas,prostate,brain,thyroid and rectal cancer.Prehabilitation plays a key role in tertiary prevention of cancer and patient symptom alleviation.The role of physical activity was studied under the entire cancer continuum,from primary to tertiary prevention.The minireview highlights the need for interventional trials involving holistic methods combing modern and traditional medicine/therapies in cancer prevention.

文摘Background:A shift from self-reports to wearable sensors for global physical activity(PA)surveillance has been recommended.The conventional use of a generic cut-point to assess moderate-to-vigorous PA(MVPA)is problematic as these cut-points are often derived from non-representative samples under non-ecological laboratory conditions.This study aimed to develop age-and sex-(age-sex)specific cut-points for MVPA based on population-standardized values as a feasible approach to assess the adherence to PA guidelines and to investigate its associations with all-cause mortality.Methods:A total of 7601 participants(20-85+years)were drawn from the 2003-2004 and 2005-2006 National Health and Nutrition Examination Surveys(NHANES).Minutes per week of MVPA were assessed with a hip-worn accelerometer.Counts per minute(CPM)were used to define an age-sex specific target intensity,representing the intensity each person should be able to reach based on their age and sex.Age-sex specific MVPA cut-points were defined as any activity above 40%of the target intensity.These population-and free-living-based age-sex specific cut-points overcome many of the limitations of the standard generic cut-point approach.For comparison,we also calculated MVPA with a generic cut-point of 1952 CPM.Both approaches were compared for assessing adherence to PA guidelines and association of MVPA with allcause mortality(ascertained through December 2015).Results:Both approaches indicated that 37%of the sample met the 150+min/week guideline.The generic cut-point approach showed a trend to inactivity with age,which was less pronounced using the age-sex specific cut-points.Overall mortality rates were comparable using generic cutpoint(hazard ratio(HR)=0.61,95%confidence interval(95%CI):0.50-0.73)or age-sex specific cut-points(HR=0.57,95%CI:0.50-0.66)for the entire sample.The generic cut-point method revealed an age-and sex-related gap in the benefits of achieving 150+min/week of MVPA,with older adults showing an 18%greater reduction in mortality rates than younger adults,and a larger difference in women than in men.This disparity disappeared when using age-sex specific cut-points.Conclusion:Our findings underscore the value of age-sex specific cut-points for global PA surveillance.MVPA defined with age-sex specific thresholds was associated with all-cause mortality and the dose-response was similar for all ages and sexes.This aligns with the single recommendation of accumulating 150+min/week MVPA for all adults,irrespective of age and sex.This study serves as a proof of concept to develop this methodology for PA surveillance over more advanced open-source acceleration metrics and other national and international cohorts.
文摘Type 2 diabetes(T2D)is a global public health issue.In 2021,537 million adults were diagnosed with T2D,corresponding to 10.5%of adults aged 20 and older.^(1)T2D increases the risks for morbidity,disability,and premature mortality,which increased by 3%between 2000 and 2019.2 Evidence is strong that maintaining a healthy diet,engaging in regular physical activity(PA),and preventing obesity can prevent or delay the incidence of T2D.

文摘Background:Taking actions to maintain a healthy lifestyle,including regular engagement in physical activity(PA)and reducing sedentary behavior(SB),may protect against the development of internalizing problems among healthy youth.However,it remains unclear whether such associations exist among youth with chronic pain who often report symptoms of depression and anxiety.To this end,we aimed to investigate the associations between independent and combined PA and/or SB patterns with indicators of internalizing problems in this vulnerable population.Methods:Data used in this cross-sectional study were retrieved from the U.S.National Survey of Children’s Health for the years 2021-2022.Specifically,caregiver proxy reports on sociodemgraphic factors and lifestyle behaviors of 4735 U.S.children and adolescents(referring to youth)aged 6-17 years were collected.We examined independent and combined patterns of PA and SB as exposures,with internalizing problems serving as outcomes of interest.Logistic regressions were used to examine the independent and combined associations of PA and/or SB patterns with anxiety and depression symptoms among youth with chronic pain while adjusting for covariates including age,sex,ethnicity,primary caregivers’education level,overweight status,and household federal poverty level.Results:Overall,our results indicated that PA was negatively associated with anxiety and depressive symptoms.Specifically,youth with chronic pain who engaged in at least 60-minute PA for 1-3 days,4-6 days,or every day reported significantly lower likelihood of experiencing symptoms of anxiety(OR=0.71,95%CI:0.60-0.84;OR=0.44,95%CI:0.36-0.53;OR=0.50,95%CI:0.40-0.63,respectively;all p-value<0.001)and depression(OR=0.63,95%CI:0.53-0.75;OR=0.38,95%CI:0.31-0.47;OR=0.46,95%CI:0.36-0.59,respectively;all p-value<0.001)symptoms compared to those with 0 days.Conversely,SB(operationalized via the proxy screen time)was positively associated with anxiety and depression symptoms.Youth with chronic pain who reported 4 or more hours of daily screen time had significantly higher odds of experiencing symptoms of anxiety(OR=2.17,95%CI:1.52-3.09,p<0.001)and depression(OR=2.30,95%CI:1.48-3.59,p<0.001).Furthermore,youth with chronic pain who engaged in higher PA levels and reported lower SB levels had a lower likelihood of experiencing symptoms of anxiety(OR=0.68,95%CI:0.52-0.87,p=0.003)and depression(OR=0.49,95%CI:0.34-0.70,p<0.001)symptoms compared to those with lower PA levels and higher SB levels.Conclusions:Higher PA levels and lower SB levels were associated with a reduced likelihood of developing anxiety and depression symptoms,which are indicative of internalizing problems,among youth with chronic pain.Future public health actions in this vulnerable population should prioritize intervention programs that promote PA engagement to reduce SB levels.

文摘Objectives Physical activity during pregnancy benefits both women and their fetuses;however,the prevalence of physical inactivity is high among pregnant women in the first trimester.This study aimed to examine physical activity patterns among pregnant Chinese women in the first trimester and clarify the characteristics associated with physical inactivity in the first trimester.Methods This cross-sectional study was conducted at three Class-A tertiary hospitals in Guangzhou,city,China,from December 2021 to June 2022.A total of 1,283 pregnant women were enrolled.The Pregnancy Physical Activity Questionnaire and a sociodemographic and obstetric data sheet collected information in the first trimester.Results The prevalence of physical inactivity among Chinese pregnant women was 51%.Pregnant women spent the most time in the domains of household/caregiving activities(median 38.25 h/week)and sedentary activities(median 54.25 h/week).Characteristics of pregnant women who were more likely to be physically inactive included younger age(OR:1.413,95%CI:1.291,1.767;P=0.002),unmarried(OR:2.976,95%CI:1.573,5.630;P=0.001),lower monthly income(OR:1.945,95%CI:1.535,2.464;P=0.001),self-paid medical care(OR:1.472,95%CI:1.140,1.900;P=0.003),nulliparous(OR:3.169,95%CI:2.504,4.009;P=0.001),inadequate knowledge about physical activity during pregnancy(OR:1.797,95%CI:1.432,2.255;P=0.001),husbands with no physical activity habits(OR:1.353,95%CI:1.081,1.693;P=0.008),and no prepregnancy physical activity habits(OR:1.832,95%CI:1.433,2.340;P=0.001).Conclusions Physical inactivity was prevalent among pregnant women in the first trimester.Promoting physical activity could be incorporated into routine antenatal care.Healthcare professionals should assess and monitor the physical activity of pregnant women and provide consultations on physical activity during their first trimester,particularly for pregnant women with characteristics associated with physical inactivity.
文摘Non-communicable diseases (NCDs) are on the rise worldwide and in developing countries like Botswana. Unhealthy eating habits and lack of proper nutrition knowledge cause non-communicable diseases and affect adolescents. It is in adolescence that eating habits are formed that persist till adulthood. Lifestyle interventions are needed to curb NCDs in adolescents. This paper reports the findings of a study that aimed to validate a lifestyle intervention program and its effect on food intake, physical activity, and nutrition knowledge. It was a clustered randomized control trial study conducted in four (4) junior secondary schools. There were 46 participants, 21 in the control and 25 in the intervention arm, who were blindly assigned to each arm by a statistician. Information and skills on nutrition were imparted using the Information, Motivation, and Behavioral Skills model. The program was implemented for eight (8) weeks hourly after school. A questionnaire was used to collect data pre- and post-intervention. Number, proportion, percentage, and independent t-test (mean and SD or median and IQR, p-value) were calculated using numerical and categorical data. The findings showed that the lifestyle intervention was valid, and there was a slight decrease in the intake of sweets among participants in both trial arms (p = 0.066). There was no significant difference in terms of food intake. Only a small number of participants still ate a few fruits, and there was no change in vegetable intake in both trial arms (p = 0.641). There was no change in the intake of fried foods in both trail arms (p = 0.402). Regarding nutrition knowledge, there was a slight significant difference of p = 0.079 between the trial arms. Though the effect of the lifestyle intervention program was not statistically significant, the results are promising, especially if the duration could be increased to a longer period and a larger sample size included.

文摘Purpose: The purpose of this umbrella review was to synthesize the evidence from systematic reviews on the benefits and harms of exercise therapy and physical activity(PA) for the secondary prevention and management of low back pain(LBP).Methods: An umbrella review was conducted to evaluate the effectiveness of exercise therapy and PA in the management and secondary prevention of LBP. A systematic search was performed in MEDLINE, CINAHL, Scopus, Web of Science, Cochrane Database of Systematic Reviews,and Physiotherapy Evidence Database(PEDro), including reference lists of relevant reviews, covering studies published between January 1,2010 and May 20, 2024. Eligible studies were systematic reviews of randomized controlled trials and observational studies, with or without meta-analyses. The primary outcome for secondary prevention was LBP recurrence, while for management, primary outcomes included pain intensity and disability, with adverse events as secondary outcomes. Data were extracted across immediate, short-term, intermediate, and longterm follow-up periods. The Grading of Recommendations Assessment, Development, and Evaluation(GRADE) framework was used to assess the certainty of evidence, and the Assessment of Multiple Systematic Reviews tool(AMSTAR) tool was applied by 2 independent reviewers(JC, QL, and/or DXMW) to evaluate the quality of the included reviews. The study was prospectively registered on the Open Science Framework(OSF).Results: A total of 70 systematic reviews were included, 43 with meta-analyses, 7 with network meta-analyses, and 20 without meta-analyses.Six(out of 10) reviews with meta-analyses for secondary prevention indicated a small benefit from general exercises and leisure-time PA(low-to-moderate certainty). For LBP management, 35(out of 36) reviews reported that exercise therapies such as Pilates, motor control,mixed exercise, Tai Chi, water-based exercises, and yoga showed small beneficial effects on pain and disability compared to minimal intervention mainly in the short-term(low-to-moderate certainty). Seven network meta-analyses favored motor control and Pilates over other forms of exercise to reduce pain(low certainty). Adverse events were reported in less than 31% of the reviews, predominantly involving postexercise soreness and temporary increases in pain, mainly in yoga-related studies. Adverse events were considered minor, and no serious adverse events were reported.Conclusion: There is low-to-moderate certainty that exercise therapy and leisure-time PA are beneficial for improving pain and preventing the recurrence of LBP. However, evidence on the potential harms of these interventions is limited, and adverse events related to exercise and PA remain under-investigated.
