RESUMO

BACKGROUND: Promoting exercise-related behavior change in rehabilitation is a challenge. The lack of integration between rehabilitation program prescriptions, behavior change interventions, and behavioral change theories is profound. Using behavior change theories properly is crucial for better adherence and promoting positive outcomes. Therefore, it is essential to bring theories that support the understanding of exercise-related behavioral change to the attention of rehabilitation practitioners. OBJECTIVE: This masterclass article aims to provide the theoretical background of theories and strategies for exercise behavior change within the physical therapy context based on acknowledged behavioral change theoretical models. METHODS: This is a narrative review that examines six behavior theories; five of them well-established, and a new (and promising) theory that has exhibited the most favorable outcomes in rehabilitation settings. The development process for this masterclass included conversations between authors, reviewing behavior theories, summarizing and discussing the theories' concepts and strategies for physical therapy. RESULTS: The included theories were self-determination theory, social-cognitive theory, the transtheoretical model, the theory of planned behavior, the health belief model, and the unifying theory of physical activity. Each theory offers a unique perspective on exercise behavior change within rehabilitation, exploring constructs such as motivation, self-efficacy, stages of change, behavioral intention, perceived threat, and the core elements of physical activity expression. CONCLUSION: These theoretical models provide a foundation for understanding and developing strategies for promoting exercise behavior change in rehabilitation. Knowing and using these theories is important for respecting the patient's individuality.

RESUMO

RESULTS: 59 patients were included (61% with COPD and 39% with ILD). BPNES factor scores were not significantly different between raters' assessments (p > 0.05). The internal consistency was 0.70 for autonomy, 0.76 for competence, and 0.80 for relatedness. Inter-rater and test-retest reliability were good to very good for autonomy (ICC = 0.78, 95%CI 0.62-0.87; ICC = 0.75, 95%CI 0.57-0.86, respectively), competence (ICC = 0.81, 95%CI 0.68-0.89; ICC = 0.65, 95%CI 0.43-0.80, respectively), and relatedness (ICC = 0.79, 95%CI 0.65-0.88; ICC = 0.70, 95%CI 0.50-0.83, respectively). Significant correlations were observed between BPNES factors and quality of life, anxiety, depression, and functional status. In conclusion, this study confirmed the reliability and construct validity of the Brazilian Portuguese version of the BPNES in patients with COPD and ILD.

RESUMO

INTRODUCTION: Lifestyle Medicine comprises six domains: diet, substance use, physical activity, stress management, social connection, and sleep. The comprehensive assessment of lifestyle is challenging, but the "Short Multidimensional Inventory on Lifestyle Evaluation" (SMILE) was developed to fill out this gap. In this paper, we describe the development and the psychometric properties (internal consistency, concurrent and convergent validity) of a shorter version of the SMILE among university students. METHODS: Data from a cross-sectional study including 369 students from 10 Brazilian universities were used. Considering a theoretical nomological net, we performed exploratory factor analysis to obtain the most parsimonious, interpretable and good-fitting model. RESULTS: The final model was called U-SMILE, comprised 24 items, and presented acceptable internal consistency (Cronbach's α = 0.73, McDonald's ω = 0.79). To evaluate the concurrent validity of the U-SMILE, we compared it to the original SMILE and found a high correlation between the instruments (Spearman's r= 0.94). Furthermore, we evaluated convergent validity by examining the U-SMILE correlation with the PHQ-9 (Spearman's r= -0.517), and GAD-7 (Spearman's r= -0.356), two validated instruments to screen for depression and anxiety, respectively. DISCUSSION: Our findings suggest that the U-SMILE is a valid instrument for assessing lifestyle among university students. We recommend that the use of U-SMILE to evaluate overall lifestyle scores rather than individual domain scores. Finally, we discuss the importance of clarifying the definitions of lifestyle and related constructs in future research.

RESUMO

OBJECTIVE: To verify the association between exercise and free time sport types and binge drinking in a large sample of adults. METHODS: Data of 718,147 adults from the "Surveillance of Risk and Protection Factors for Chronic Diseases by Telephone Survey" were used. We described the demographic and behavioral variables, and negative binomial regression analyzed the association between exercise and free time sport types and binge drinking adjusted by demographics variables, body mass index status, and television time. RESULTS: Outdoor walking/running was the most common exercise reported (20.0%, 95% confidence interval [CI], 19.8%-20.2%), followed by team sports (8.1%; 95% CI, 8.0%-8.2%) and strengthening (8.0%; 95% CI, 7.9%-8.1%). The prevalence of binge drinking for each exercise and free time sport type ranged from 6.9% (water aerobics) to 31.9% (team sports). Participants engaging in strengthening (prevalence ratio = 1.12; 95% CI, 1.04-1.21, P = .002) and team sports (prevalence ratio = 1.11; 95% CI, 1.07-1.17, P < .001) were more likely to binge drink more frequently in the past 30 days than inactive participants. CONCLUSIONS: It appears that the participants' profile plays an important role in the underlying social context of this association. Participants with more frequent strengthening and less frequent team sports practice, who were primarily younger and single, were more likely to binge drink frequently.

RESUMO

The training load is associated with injury risk in a variety of sports. This study aimed to evaluate the association between the internal training load and injury risk in Brazilian professional soccer players. The data were collected from 32 soccer players across two full seasons (2017 and 2018). The rating of perceived exertion (RPE) for every training/match session was used as an internal load variable. The cumulative training load from 3 and 4 weeks (C3 and C4) and the acute:chronic workload ratio (ACWR) were calculated. A generalized estimating equation analysis was applied to examine associations of non-contact muscle injuries with C3, C4 and ACWR. A total of 33 injuries were recorded across the two full seasons. A significant association was found between cumulative training load for three (C3, p = 0.003) and four weeks (C4, p = 0.023) and the occurrence of injuries. Players in the "high load" group presented greater injury risk in relation to the "moderate load" group (C4: OR = 4.5; IC 95% 1.5-13.3; C3: OR = 3.7; IC 95% 1.7-8.1). There was no association between ACWR and injury occurrence. The athletes exposed to a high cumulative load in a period of 3 to 4 weeks presented higher injury risk in comparison to those who had moderate cumulative training loads. Besides that, there was no association between ACWR and injury occurrence.

RESUMO

OBJECTIVES: To examine the theoretical substitutions of screen exposure, non-screen sitting time, moderate and vigorous physical activity with depressive and anxiety symptoms in South American adults during the COVID-19 pandemic. DESIGN: A cross-sectional study during the first months of the COVID-19 pandemic with data from 1981 adults from Chile, Argentina, and Brazil. METHODS: Depressive and anxiety symptoms were assessed using the Beck Depression and Anxiety Inventories. Participants also reported physical activity, sitting time, screen exposure, sociodemographic, and tobacco use data. Isotemporal substitution models were created using multivariable linear regression methods. RESULTS: Vigorous physical activity, moderate physical activity, and screen exposure were independently associated with depression and anxiety symptoms. In adjusted isotemporal substitution models, replacing 10 min/day of either screen exposure or non-screen sitting time with any intensity of physical activity was associated with lower levels of depressive symptoms. Improvements in anxiety symptoms were found when reallocating either screen exposure or non-screen sitting time to moderate physical activity. Furthermore, replacing 10 min/day of screen exposure with non-screen sitting time was beneficially associated with anxiety (B = -0.033; 95 % CI = -0.059, -0.006) and depression (B = -0.026; 95 % CI = -0.050, -0.002). CONCLUSIONS: Replacement of screen exposure with any intensity of physical activity or non-screen sitting time could improve mental health symptoms. Strategies aiming to reduce depressive and anxiety symptoms highlight physical activity promotion. However, future interventions should explore specific sedentary behaviors as some will relate positively while others negatively.

RESUMO

Hypertrophic pachymeningitis (HP) is a rare and chronic inflammatory disorder presenting as localized or diffuse thickening of the dura mater. It can be idiopathic or an unusual manifestation of immune-mediated, infectious, and neoplastic conditions. Although some cases may remain asymptomatic, HP can lead to progressive headaches, cranial nerve palsies, hydrocephalus, and other neurological complications, which makes its recognition a fundamental step for prompt treatment. Regarding the diagnosis workup, enhanced MRI is the most useful imaging method to evaluate dural thickening. This article addresses the MR imaging patterns of immune-mediated HP, including immunoglobulin G4-related disease, neurosarcoidosis, granulomatosis with polyangiitis, rheumatoid pachymeningitis, and idiopathic HP. The main infectious and neoplastic mimicking entities are also discussed with reference to conventional and advanced MR sequences.

RESUMO

BACKGOUND: Although obesogenic behaviors have been found to be related to social isolation, evidence-based person-centered approaches are lacking. This study investigated the association between clusters of obesogenic behavior - derived from a data-driven process - and social isolation among Brazilian adolescents. METHODS: Data from the National Adolescent School-based Health Survey (PeNSE) 2015 were analyzed. A total of 100,794 9th-grade students (51.3% females; 14.3 ± 0.1 years old) enrolled in 3,040 public and private high schools participated in the study. Social isolation was assessed by two outcomes (i.e., perceived loneliness and lack of close friends). A two-step cluster analysis was conducted to identify patterns of obesogenic behaviors with the input of leisure-time physical activity (PA), sitting time as a proxy of sedentary behavior (SB), and the weekly consumption of healthy and unhealthy food. Crude and adjusted binary logistic regression models were applied to evaluate the associations between the clusters of obesogenic behaviors and social isolation variables in adolescents. RESULTS: Three clusters were identified. Adolescents in the "Health-promoting SB and diet" (32.6%; OR = 0.69; 95% CI = 0.62-0.76) and "Health-promoting PA and diet" (44.9%; OR = 0.73; 95% CI = 0.67-0.79) clusters had lower odds of loneliness compared to those in the "Health-risk" cluster (22.5%). Those belonging to the "Health-promoting PA and diet" cluster were more likely to report having close friends (OR = 1.19; 95% CI = 1.00-1.41) than those in the "Health-risk" cluster. CONCLUSION: Adolescents in clusters where positive behaviors outweighed negative ones were less likely to perceive themselves as lonely and without close connections.

RESUMO

Although there is consistent evidence of the beneficial effects of leisure physical activity (PA) on mental health, the role of PA in the domestic, transport, and occupational domains is inconclusive. This study aimed to analyze the relationship between domain-specific PA and depressive symptoms and examine whether the association is moderated by age in a representative sample of the Brazilian population. Cross-sectional data of 89,923 (52.4% female) individuals aged ≥15 years were analyzed. Depressive symptoms were assessed using the Patient Health Questionnaire-9. Physical activity (min/week) performed in different domains (domestic, transport, occupation, and leisure) was self-reported. Generalized additive models with penalized splines were used to explore associations. Lower leisure-time PA and higher levels of PA in the domestic, occupational, and transport domains at distinct PA thresholds were associated with higher depressive symptoms. Leisure PA, even at lower levels, was associated with lower depressive symptoms compared to no PA at all. The increase in depressive symptoms as a function of occupational PA was observed only at PA levels higher than 40 h/week. Although non-leisure PA levels were related to higher depressive symptoms among the total sample, higher domestic and transport PA levels were related to lower depressive symptoms among older adults. This study provides insights into the non-linearity and age-group dependence of the relationship between domain-specific PA and depressive symptoms in a middle-income country. The evidence suggests that care should be taken on recommending PA regardless of context or domain.

RESUMO

Obesogenic behaviors have been individually associated with bullying during adolescence. However, physical activity, sedentary behavior, and diet manifest themselves in synergy and even behavioral profiles in which positive and negative behaviors coexist can be more positively associated with psychosocial outcomes. The present study aimed to analyze the association between clusters of obesogenic behaviors and different bullying roles in Brazilian adolescents. This cross-sectional study used data from the Brazilian School-based Health Survey-PENSE, 2015. A total of 100,794 male and female adolescents of the ninth-grade elementary school participated in the study. Students responded to an electronic questionnaire. Clusters of obesogenic behavior consisted of physical activity, exposure to sedentary behavior, and diet, and the different roles in bullying were: participant, victim, bully, and bully-victim. Binary logistic regression with 95% confidence intervals (CI) was used for data analysis (p < .05). Multiple adjustments and complex sampling procedures were employed. Adolescents in the cluster "Health-promoting sedentary behavior and Diet" had reduced chances of participating in bullying (odds ration [OR] = 0.70; 95% CI [0.64, 0.76]), of being a victim (OR = 0.87; 95% CI = 0.76-0.99), and being the bully (OR = 0.65; 95% CI [0.59, 0.71]); and those from the cluster "Health-promoting physical activity and Diet" had reduced chances of participating (OR = 0.81; 95% CI [0.76, 0.87]), being a victim of bullying (OR = 0.86; 95% CI [0.76, 0.98]), being the bully (OR = 0.79; 95% CI [0.72, 0.85]), and being a bully-victim (OR = 0.74; 95% CI [0.61, 0.90]), when compared to those from the "health-risk" cluster in the adjusted analysis. Clusters of obesogenic behavior may reduce adolescent bullying: victim, bully, and bully-victim benefit when exposed to healthier behavioral profiles. The school setting must recognize bullying as a problem and therefore simultaneously promote multi-component interventions to tackle physical activity, sedentary behavior, and eating behavior. Outcomes other than obesity should be acknowledged when promoting obesogenic behaviors.
