Perceptions of medical doctors and patients about imaging for people with low back pain: A qualitative study.

BACKGROUND: Low-value care is the use of substitutive/ineffective/harmful strategies based on available evidence, and it is considered one of the main contributors to the burden related to low back pain in health care systems. The use of routine imaging for patients with low back pain is the main example of inappropriate care. Therefore, understanding the perceptions of medical doctors and patients from Brazil about this practice may help propose strategies to reduce imaging rates. OBJECTIVE: To investigate the perceptions of medical doctors and patients about imaging for the diagnosis of nonspecific low back pain. DESIGN: A qualitative study using the framework analysis method. SETTINGS: Primary and secondary care. PARTICIPANTS: Fifteen patients with low back pain and 15 doctors participated in this study. DATA COLLECTION: Sociodemographic data were collected from all participants, and the interviews were performed using a set of questions created based on the literature. MAIN RESULTS: Patients and doctors believe that the main reason for ordering imaging tests is to identify the source of pain, and imaging could be useful for tracking disease progression over time or if there is a lack of improvement after treatment. Patients' expectations and pressures play a role in the decision to order imaging tests, but clinicians believe that education is the preferred strategy to reduce imaging rates. CONCLUSION: Identifying the source of pain, tracking the disease progression, and patients' expectations and pressures were the main drivers of imaging requests for low back pain. Educational strategies were suggested to reduce the use of routine imaging.

Clinical indicators to monitor health care in low back pain: a scoping review.

Clinical care indicators for low back pain can be used to monitor healthcare practices and consequently be used to evaluate success of strategies to improve care quality. The aim of this study was to identify the clinical care indicators that have been used to measure appropriateness of health care for patients with low back pain. We conducted a systematic search of five electronic databases and Google to identify clinical care indicators that have been used to measure any aspect of care for people with low back pain. Care indicators were narratively described according to their type (i.e. structure, process, or outcomes) and categorized by their purpose (e.g. to measure aspects related to assessment, imaging requests, treatment/prevention, and outcomes). A total of 3562 and 2180 records were retrieved from electronic databases and Google searches, respectively. We identified 280 indicators related to low back pain care from 40 documents and publications. Most quality indicators were process indicators (n = 213, 76%), followed by structure (n = 41, 15%) and outcome indicators (n = 26, 9%). The most common indicators were related to imaging requests (n = 41, 15%), referral to healthcare providers (n = 30, 11%), and shared decision-making (n = 21, 7%). Our review identified a range of clinical care indicators that have been used to measure the quality of health care for people with low back pain. Our findings will support a Delphi study to reach international consensus on what would be the most important and feasible indicators for a minimum dataset to be collected globally.

Clinical care standards for the management of low back pain: a scoping review.

The objective of this study is to compare and contrast the quality statements and quality indicators across clinical care standards for low back pain. Searches were performed in Medline, guideline databases, and Google searches to identify clinical care standards for the management of low back pain targeting a multidisciplinary audience. Two independent reviewers reviewed the search results and extracted relevant information from the clinical care standards. We compared the quality statements and indicators of the clinical care standards to identify the consistent messages and the discrepancies between them. Three national clinical care standards from Australia, Canada, and the United Kingdom were included. They provided from 6 to 8 quality statements and from 12 to 18 quality indicators. The three standards provide consistent recommendations in the quality statements related to imaging, and patient education/advice and self-management. In addition, the Canadian and Australian standards also provide consistent recommendations regarding comprehensive assessment, psychological support, and review and patient referral. However, the three clinical care standards differ in the statements related to psychological assessment, opioid analgesics, non-opioid analgesics, and non-pharmacological therapies. The three national clinical care standards provide consistent recommendations on imaging and patient education/advice, self-management of the condition, and two standards (Canadian and Australian) agree on recommendations regarding comprehensive assessment, psychological support, and review and patient referral. The standards differ in the quality statements related to psychological assessment, opioid prescription, non-opioid analgesics, and non-pharmacological therapies.

Does the Number of Comorbidities Predict Pain and Disability in Older Adults With Chronic Low Back Pain? A Longitudinal Study With 6- and 12-Month Follow-ups.

BACKGROUND AND PURPOSE: People who live longer often live with multimorbidity. Nevertheless, whether the presence of multimorbidity affects pain and disability in older adults with chronic low back pain (LBP) remains unclear. The aim of this study was to investigate whether multimorbidity predicts pain intensity and disability at 6- and 12-month follow-ups in older adults with chronic LBP. METHODS: This was a prospective, longitudinal study with 6- and 12-month follow-ups. Participants with chronic LBP (age ≥ 60 years) were recruited and interviewed at baseline, 6 months, and 12 months. Self-reported measures included the number of comorbidities, assessed through the Self-Administered Comorbidity Questionnaire, pain intensity, assessed with the 11-point Numerical Rating Scale, and disability, assessed with the Roland-Morris Disability Questionnaire. Data were analyzed using univariate and multivariate regression models. RESULTS AND DISCUSSION: A total of 220 participants were included. The number of comorbidities predicted pain intensity at 6-month (ß= 0.31 [95% CI: 0.12 to 0.50]) and 12-month (ß= 0.29 [95% CI: 0.08 to 0.50]) follow-ups. The number of comorbidities predicted disability at 6-month (ß= 0.55 [95% CI: 0.20 to 0.90]) and 12-month (ß= 0.40 [95% CI: 0.03 to 0.77]) follow-ups. CONCLUSION: The number of comorbidities at baseline predicted pain and disability at 6-month and 12-month follow-ups in older adults with chronic LBP. These results highlight the role of comorbidities as a predictive factor of pain and disability in patients with chronic LBP, emphasizing the need for timely and continuous interventions in older adults with multimorbidity to mitigate LBP-related pain and disability.

Process evaluation of the implementation of an evidence-based model of care for low back pain in Australian emergency departments.

BACKGROUND: The Sydney Health Partners Emergency Department (SHaPED) trial targeted ED clinicians and evaluated a multifaceted strategy to implement a new model of care. The objective of this study was to investigate attitudes and experiences of ED clinicians as well as barriers and facilitators for implementation of the model of care. DESIGN: A qualitative study. METHODS: The EDs of three urban and one rural hospital in New South Wales, Australia participated in the trial between August and November 2018. A sample of clinicians was invited to participate in qualitative interviews via telephone and face-to-face. The data collected from the interviews were coded and grouped in themes using thematic analysis methods. RESULTS: Non-opioid pain management strategies (i.e., patient education, simple analgesics, and heat wraps) were perceived to be the most helpful strategy for reducing opioid use by ED clinicians. However, time constraints and rotation of junior medical staff were seen as the main barriers for uptake of the model of care. Fear of missing a serious pathology and the clinicians' conviction of a need to provide something for the patient were seen as barriers to reducing lumbar imaging referrals. Other barriers to guideline endorsed care included patient's expectations and characteristics (e.g., older age and symptoms severity). CONCLUSIONS: Improving knowledge of non-opioid pain management strategies was seen as a helpful strategy for reducing opioid use. However, clinicians also raised barriers related to the ED environment, clinicians' behaviour, and cultural aspects, which should be addressed in future implementation efforts.

Association of Musculoskeletal Pain With Sedentary Behavior in Public School Teachers: The Role of Habitual Physical Activity.

BACKGROUND: Sedentary behavior has been associated with musculoskeletal pain in school teachers. However, our hypothesis is that physical activity practice could mitigate this association. AIM: The aim of this study was to investigate the relationship of musculoskeletal pain with high screen-based sedentary behavior among public school teachers and whether physical activity could mitigate this relationship. METHOD: A sample of 246 teachers from 13 public schools were assessed (45.0 ± 10.4 years, 76.0% of women). Musculoskeletal pain was assessed using the Nordic Musculoskeletal Questionnaire, screen-based sedentary behavior was measured considering the sum of screen time in television, computer, and smartphone/tablet, and physical activity using the Baecke habitual physical activity questionnaire. Binary logistic regression was used to verify the associations between high screen-based sedentary behavior and musculoskeletal pain in school teachers (Model 1-unadjusted; Model 2-adjusted by age, sex, and socioeconomic status; Model 3-variables of Model 2 + adjusted by physical activity). RESULTS: High screen-based sedentary behavior was associated with pain in neck (odds ratio = 2.09; 95%confidence interval = 1.08-4.04), upper back (odds ratio = 2.21; 95%confidence interval = 1.07-4.56), and low back (odds ratio = 1.91; 95%confidence interval = 1.00-3.65). However, after inserting the variables, including physical activity, these associations were mitigated. CONCLUSIONS: High screen-based sedentary behavior was associated with musculoskeletal pain in public school teachers. However, this relationship was mitigated after the inclusion of confounding variables, including physical activity.

Sedentary behavior is associated with musculoskeletal pain in adolescents: A cross sectional study.

BACKGROUND: High prevalence of back pain has been observed in adolescents. Sedentary behavior (SB) is considered a risk factor for musculoskeletal pain. The association between back pain and SB in the pediatric/adolescent population is not well established. OBJECTIVE: To investigate the association between SB and low back and neck pain in adolescents according to sex. METHODS: This is a cross-sectional study with children and adolescents aged 10-17 years, randomly recruited from public and private schools in Presidente Prudente, Brazil. All students enrolled in the selected schools were eligible to participate. SB was evaluated by adding the number of hours of use of screen devices, such as television, computer, video game, and smartphone/tablet. To assess neck and low back pain, the Nordic Musculoskeletal Questionnaire was used. Physical activity and socioeconomic status were assessed by the Baecke Questionnaire and the Brazilian Criteria for Economic Classification (ABEP), respectively. Odds ratio (OR) from Binary Logistic Regression in the unadjusted and adjusted model (physical activity, abdominal obesity, and socioeconomic status) showed the relationship between musculoskeletal pain and SB. RESULTS: A total of 1011 adolescents (557 girls) with a mean ± standard deviation age of 13.2±2.4 years were included. Moderate (OR = 1.80; 95%CI: 1.00, 3.23) and high (OR = 1.91; 95%CI: 1.02, 3.53) SB were associated with neck pain in girls. In boys, moderate SB (OR = 2.75; 95%CI: 1.31, 5.78) were associated with neck pain. Moderate (OR = 2.73; 95%CI: 1.45, 5.02) and high (OR = 2.49; 95%CI: 1.30, 4.76) SB were associated with low back pain only in girls. CONCLUSION: Moderate and high SB were associated with neck pain in girls and boys, while moderate and high SB were associated with low back pain only in girls.

Adding Physical Activity Coaching and an Activity Monitor Was No More Effective Than Adding an Attention Control Intervention to Group Exercise for Patients With Chronic Nonspecific Low Back Pain (PAyBACK Trial): A Randomized Trial.

OBJECTIVE: To investigate whether adding physical activity coaching and an activity monitor enhanced the effects of a group exercise program on pain intensity and disability for people with chronic nonspecific low back pain. DESIGN: Randomized controlled trial with concealed allocation, intention-to-treat analysis, and blinding of participants and assessors. METHODS: One hundred sixty participants with chronic nonspecific low back pain who were aged between 18 and 60 years and seeking care at an outpatient physiotherapy clinic participated. Both groups received supervised group exercise therapy. The intervention group also received physical activity coaching sessions aimed at improving physical activity, and physical activity electronic feedback delivered by an activity monitor. The attention control group received modified approaches of coaching sessions and an activity monitor. Disability was measured using the Roland Morris Disability Questionnaire (0-24), and pain intensity was measured using the 11-point Numerical Rating Scale (0-10). Linear mixed models were performed to test for differences between groups. RESULTS: There were no differences between groups for reductions in disability (mean difference [MD] = -0.5 out of 24 points; 95% confidence interval [CI]: -2.2, 1.1) and pain intensity (MD = -0.4 out of 10 points; 95% CI: -1.3, 0.5) at 3-month follow-up. There were no between-groups differences at 6- and 12-month follow-up assessments. CONCLUSION: Adding targeted physical activity coaching and an activity monitor did not reduce pain intensity or disability more than an attention control approach in participants with chronic low back pain who were undertaking a group exercise program. J Orthop Sports Phys Ther 2022;52(5):287-299. doi:10.2519/jospt.2022.10874.

Occupational Physical Activity Was Associated With Disability Levels at 6-Month Follow-Up of Patients With Chronic Nonspecific Low Back Pain: A Prospective Cohort Study.

BACKGROUND: Physical activity plays an important role in the prognosis of chronic low back pain (LBP); however, whether physical activity predicts pain intensity and disability remains unknown. This study investigated whether objective and subjective physical activity measures predict pain intensity and disability levels 6 months later in patients with chronic LBP. METHODS: Patients with chronic LBP seeking care at 2 outpatient physiotherapy clinics were recruited. At baseline assessment, we collected anthropometric/sociodemographic data, duration of symptoms, pain intensity, disability, and physical activity (accelerometer and questionnaire). After 6 months, we reassessed pain and disability. Multivariable regression analyses were performed to investigate the association of physical activity measures with pain and disability at follow-up. RESULTS: A total of 179 patients with chronic LBP were included. High occupational physical activity at baseline predicted disability at 6-month follow-up (B = 1.22; 95% confidence interval, 0.21 to 2.21) after controlling for age and baseline disability, meaning that for every 1-point increase in occupational physical activity, disability increased on average by 1.22 point. The remaining physical activity measures showed no association with pain intensity or disability at follow-up. CONCLUSION: Higher perceived levels of occupational physical activity predicted higher disability levels at 6-month follow-up in patients with chronic LBP.

Does sedentary behaviour contribute to the development of a new episode of low back pain? A systematic review of prospective cohort studies.

OBJECTIVE: To investigate whether the sedentary behaviour contributes to the development of new episodes of low back pain in adults. METHODS: Searches were performed in five electronic databases from their inception to March 2022. Prospective cohort studies with people without low back pain at baseline investigating the effect of sedentary behaviour on the development of new episodes of low back pain at follow-up were considered eligible. Two independent authors screened, extracted the data and assessed the risk of bias of included studies. An adapted version of the Quality In Prognosis Studies (QUIPS) tool was used to assess the risk of bias. Meta-analyses were performed using random effect models to obtain a pooled risk ratio (RR) and 95% confidence intervals (CIs). Grading of Recommendations Assessment, Development and Evaluation (GRADE) approach was used to assess the overall certainty of the evidence. RESULTS: Ten studies were included in this review, with a total sample ranging from 107 to 57,504 participants and mean age ranging from 21.7 to 53.6 years. Most studies (n = 9) assessed sedentary behaviour using self-reported methods, including validated questionnaires or single questions, except for one study that used video recording. The overall risk of bias of the included studies was low. Pooled analysis showed that people classified as sedentary or spending more time in sedentary activities were not likely to develop a new episode of low back pain (RR 1.01, 95% CI 0.98-1.04, I2  = 9%, n = 9 studies, moderate evidence). CONCLUSION: Sedentary behaviour probably does not contribute to the development of new episodes of low back pain in an adult population. SIGNIFICANCE: Sedentary behaviour does not appear to increase the chances of developing a new episode of low back pain. This might imply that health lifestyle contributors seem to be more related to the amount and type of physical activity, but not the amount of sedentary time. However, studies evaluating the relationship of the sedentary and physical activity with the development of a new episode of low back pain are still needed.

Relationship of sleep quality with screen-based sedentary time and physical activity in adolescents - the moderating effect of body mass index.

OBJECTIVE: To analyze the association of sleep quality with reported screen-based sedentary time and reported physical activity, among overweight adolescents. METHODS: Adolescents aged 10 to 17 years enrolled in public and private schools were included. Data collection was carried out during the school semesters of 2014-2015 and participants who did not participate in all evaluations were excluded. Sleep quality and physical activity were assessed by validated questionnaires. Screen-based sedentary time was assessed by self-reported mean daily hours spent on television, computer, smartphone/tablet, and videogames. Body mass index was objectively measured and adolescents were classified into normal weight and overweight according to cutoff points for age and sex. Multiple linear regression models adjusted by covariates (age, sex, ethnicity, and socioeconomic status) were used to analyze the relationship between variables. RESULTS: A total of 1008 adolescents were assessed, with a mean age of 13.2 ± 2.4 years and a mean body mass index of 20.4 ± 4.3 kg/m2. Overweight was observed in 28.0% of sample, while 53.0% reported non-white ethnicity. Self-reported screen-based sedentary time was significantly related to poor sleep quality in adolescents (ß = 0.116, p = 0.005), remaining significant only in those who were normal weight (ß = 0.101, p = 0.007) in sensitivity analysis. Self-reported physical activity showed no relationship with sleep quality in both normal weight and overweight adolescents. CONCLUSION: Self-reported screen-based sedentary time was associated with poor sleep quality in adolescents, mainly among those with normal weight. The time spent on screen-based sedentary activities can impair sleep quality even in normal weight adolescents.

Do Patients with Acute Low Back Pain in Emergency Departments Have More Severe Symptoms than Those in General Practice? ASystematic Review with Meta-Analysis.

INTRODUCTION: There is a common belief that patients presenting to emergency departments have more severe pain levels and functional limitations than those who are seen in general practice. The aim of this systematic review was to compare pain and disability levels of patients with acute low back pain presenting to general practice vs those presenting to emergency departments. METHODS: Electronic searches were conducted in MEDLINE, EMBASE, and CINAHL from database inception to February 2019. Observational studies including patients with acute non-specific low back pain presenting to emergency departments and/or general practice were eligible. Pain and/or disability scores expressed on a 0-100 scale were the primary outcomes. Risk of bias was evaluated with a validated tool for observational studies, and the overall quality of evidence was assessed with Grading of Recommendations Assessment, Development and Evaluation (GRADE) approach. Meta-analysis with random effects and meta-regression were used to test for differences between the two settings. RESULTS: We included 12 records reporting results for 10 unique studies with a total of 6,999 participants from general practice (n = 6) and emergency departments (n = 4). There was low-quality evidence (downgraded for indirectness and inconsistency) that patients presenting to emergency departments had higher pain scores than those in general practice, with a mean difference of 17.3 points (95% confidence interval: 8.8 to 25.9 on a 0-100 scale). Similarly, there was low-quality evidence (downgraded for indirectness and inconsistency) that patients presenting to emergency departments had higher disability scores than those in general practice (mean difference: 21.7; 95% confidence interval: 4.6 to 38.7 on a 0-100 scale). CONCLUSION: Patients with acute non-specific low back pain presenting to emergency departments may report higher levels of pain and disability than those seen in general practice.

Effectiveness of brief patient information materials for promoting correct beliefs about imaging and inevitable consequences of low back pain: A randomised controlled trial.

OBJECTIVE: To investigate what format for providing patient information (i.e. written summary, infographic or video animation) is most effective for promoting correct beliefs about imaging and inevitable consequences of low back pain (LBP). DESIGN: Randomised controlled trial. SETTING/PATIENTS: One hundred and fifty-nine patients with non-specific LBP were recruited from outpatient physiotherapy clinics. INTERVENTION: Participants were randomised to receive patient information in one of three formats: video animation, infographic or written summary. Patients were allowed to read or watch the materials for up to 20 min. MEASUREMENTS: Outcome were assessed before and immediately after the intervention. The primary outcome was the Back Beliefs Questionnaire. The secondary outcome was beliefs about imaging for LBP assessed by two questions. RESULTS: All 159 patients completed the study. Our findings revealed no difference between groups for the Back Beliefs Questionnaire. Correct beliefs about imaging were more likely with the infographic than the video animation (Question 1- Odds Ratio [OR] = 3.9, 95% confidence interval [CI]: 1.7, 8.7; Question 2- OR = 6.8, 95%CI: 2.7, 17.2) and more likely with the written summary than the video animation (Question 1- OR = 3.3, 95%CI: 1.5, 7.4; Question 2- OR = 3.7, 95%CI: 1.6, 8.5). No difference between infographic and written summary formats were reported for the questions assessing LBP imaging beliefs. CONCLUSION: The three materials were equally effective in improving patient's general beliefs about LBP care. However, the traditional written summary or infographic formats were more effective than the video animation format for improving beliefs about imaging for LBP.

Recommendations for Diagnosis and Treatment of Lumbosacral Radicular Pain: A Systematic Review of Clinical Practice Guidelines.

The management of patients with lumbosacral radicular pain (LRP) is of primary importance to healthcare professionals. This study aimed to: identify international clinical practice guidelines on LRP, assess their methodological quality, and summarize their diagnostic and therapeutic recommendations. A systematic search was performed (August 2019) in MEDLINE, PEDro, National Guideline Clearinghouse, National Institute for Health and Clinical Excellence (NICE), New Zealand Guidelines Group (NZGG), International Guideline Library, Guideline central, and Google Scholar. Guidelines presenting recommendations on diagnosis and/or treatment of adult patients with LRP were included. Two independent reviewers selected eligible guidelines, evaluated quality with Appraisal of Guidelines Research & Evaluation (AGREE) II, and extracted recommendations. Recommendations were classified into 'should do', 'could do', 'do not do', or 'uncertain'; their consistency was labelled as 'consistent', 'common', or 'inconsistent'. Twenty-three guidelines of varying quality (AGREE II overall assessment ranging from 17% to 92%) were included. Consistent recommendations regarding diagnosis are ('should do'): Straight leg raise (SLR) test, crossed SLR test, mapping pain distribution, gait assessment, congruence of signs and symptoms. Routine use of imaging is consistently not recommended. The following therapeutic options are consistently recommended ('should do'): educational care, physical activity, discectomy under specific circumstances (e.g., failure of conservative treatment). Referral to a specialist is recommended when conservative therapy fails or when steppage gait is present. These recommendations provide a clear overview of the management options in patients with LRP.

Characteristics Associated With People With Chronic Low Back Pain Meeting Physical Activity Guidelines and Recommendations for Sedentary Behavior: A Cross-Sectional Study.

OBJECTIVE: The purpose of this study was to identify factors associated with meeting physical activity guidelines and sedentary recommendations in people with chronic low back pain (LBP). METHODS: This was a cross-sectional study including 171 people with chronic LBP. Trained assessors collected information regarding demographic, anthropometric, and clinical data. Physical activity levels and sedentary time were objectively measured using a tri-axial accelerometer. Participants were classified as being physically active (ie, performing at least 150 minutes of moderate or 75 minutes of vigorous physical activity per week) and sedentary (ie, more than 8 hours of time spent in sedentary activities per day). Multivariable logistic regression analyses were used to determine the association of being physically active or sedentary with the range of demographic, anthropometric and clinical variables. RESULTS: Our results showed that although lower body mass index (odds ratio [OR] = 0.91; 95% CI: 0.85-0.98) and higher self-reported levels of leisure time physical activity (OR = 3.46; 95% CI: 1.94-6.15) were associated with being physically active, lower self-reported levels of physical activity at work (OR = 0.56; 95% CI: 0.39-0.81) was associated with being sedentary. CONCLUSION: Our findings showed that, in people with LBP, lower body mass index and higher levels of leisure time physical activity may be important factors for identifying those physically active. In contrast, lower levels of physical activity at work may be considered when identifying sedentary people with LBP. Future studies should consider these factors when designing interventions aiming to promote physical activity and decrease sedentary behavior in this population.

Daily activity limitations and physical activity encouragement influence adolescents seeking health care for neck and low back pain.

BACKGROUND: Understanding the factors associated with care-seeking behaviour in adolescents with spinal pain will inform health care professionals and guide a better decision-making. OBJECTIVE: To identify factors, including parents' habits and behaviour, related to care-seeking in adolescents with neck pain or low back pain (LBP). STUDY DESIGN: A cross-sectional study. METHODS: Adolescents between 10 and 17 years were randomly recruited from public schools. The proportion of adolescents with neck or LBP and those who had sought care for neck and LBP were assessed with the Nordic Musculoskeletal questionnaire. Daily activity limitation and the frequency of parents' habits and behaviour were collected using self-reported questions. Logistic regression analyses were performed to investigate if the following factors were associated with adolescents' care-seeking behaviour due to neck or LBP: daily activity limitations, physical activity (PA) domains, items of the social support scale. RESULTS: The prevalence of adolescents reporting neck or LBP was 31.4% (318 out of 1011). Of these, 35.8% (n = 114) sought care for neck or low back pain. Activity limitations related to neck or LBP (OR: 5.83, 95% CI: 3.46 to 9.84), higher PA levels at school (OR: 1.67, 95% CI: 1.02 to 2.75), and PA encouragement (OR: 2.73, 95% CI: 1.27 to 5.85) were associated with care-seeking in adolescents with neck or LBP. CONCLUSION: Adolescents with activity limitations due to neck or LBP, higher PA levels at school and encouraged by parents or friends to practice PA were more likely to seek care for their neck or LBP.

Physical activity across life stages and sleep quality in adulthood - an epidemiological study.

OBJECTIVE: To analyze the association between the continuous physical activity (PA) at different life stages with sleep quality in adults. METHODS: This is an observational study with a cross-sectional design. A sample of 843 adults (61.7% female) with a mean age of 56.6 (±18.3) years was randomly selected. The PA at different life stages was assessed retrospectively in childhood and adolescence, and the current PA was assessed by Baecke Physical Activity Questionnaire. Sleep quality was assessed using the Mini-Sleep Questionnaire. Variables of sex, age group, ethnicity, socioeconomic status, and current physical activity were covariates. The association between continuous PA at different life stages with sleep quality was analyzed by binary logistic regression models. RESULTS: Overweight adults who practiced PA in adolescence were 46% less likely to have poor sleep quality when compared to those who did not practice physical activity in this life stage (Odds ratio = 0.54, p = 0.031). Adults who continued to practice PA at youth and adulthood were 49% less likely to have poor sleep quality when compared to those without continuous PA (Odds ratio = 0.51, p = 0.009). CONCLUSIONS: Poor sleep quality was negatively associated with continuous PA between youth and adulthood in overall sample and negatively associated with PA in adolescence among overweight adults.
