RESUMEN
BACKGROUND: Lifestyle and habits, cardiovascular risk factors (CRF), bone and mental health, dietary habits, physical activity, among others are developed in childhood and adolescence. Family environment has shown to play an important role in these outcomes. However, whether the parent-child relationship lifestyle habits and health parameters can be influenced by physical activity patterns still unclear. The objective of this study will be to monitor and investigate the associations between lifestyle habits between parents and their children longitudinally, as well as verify whether in more active parents, the possible associations with lifestyle habits are different from those of parents considered less active. METHODS: The sample will consist of parents (father, mother, or both) and their children /adolescents. The participants will be recruited through public call by flyers spread across all the regions of the city and also through social media. The health parameters will include cardiovascular (cardiac autonomic modulation, blood pressure and resting heart rate), bone mineral density, anthropometric indices, handgrip strength, mental health (quality of life, anxiety and depression symptoms and stress), self-reported morbidities and musculoskeletal pain. Lifestyle habits will include physical activity levels, sedentary behavior, sleep parameters, eating patterns, smoking and alcohol consumption. Sociodemographic variables of age, sex, ethnicity and socioeconomic status will be considered as covariates. The follow-up visits of data collection will be scheduled after a period of 12 months from the baseline assessment during every twelve months. DISCUSSION: The family environment has great potential to determine lifestyle habits in children and adolescents. Based on the results presented in the present study, we hope that health promotion actions can be better designed in the family environment.
RESUMEN
BACKGROUND: Practicing sports during childhood and adolescence provides benefits to cardiac autonomic modulation (CAM) at these stages of life. However, it is not known whether these benefits to CAM persist into adulthood. Therefore, the objective of this study was to analyze the association of early sports practice (sports practice in childhood and/or adolescence) with CAM in adult life, regardless of habitual moderate-to-vigorous PA. METHODS: The sample of the present study consisted of 242 adults (141 women and 101 men; age: 41.99 ± 16.24). The assessment of CAM was performed using heart rate variability indices. Sports practice in childhood and adolescence was assessed using a questionnaire. The intensity of physical activity was assessed using accelerometry. To analyze the association between previous sports practice (childhood and/or adolescence) and CAM, the Generalized Linear Model was adopted, considering CAM indices as continuous variables and early sports practice as a 3-fold factor (no sports practice; sports practice in childhood or adolescence; and sports practice in both childhood and adolescence) adjusted by sex, age, socioeconomic condition, and moderate to vigorous PA. RESULTS: Sports practice in childhood was associated with the average standard deviation of all normal RR intervals expressed in milliseconds (SDNN): ß = 5.89; 95%CI: 0.25;11.52, and the standard deviation of the long-term intervals between consecutive heartbeats (SD2): ß = 7.63; 95%CI:1.04; 14.23 indices. Sports practice in adolescence was associated in adulthood with the SD2 index: ß = 7.37; 95%CI: 0.71;14.04. Sports practice in at least one of the periods (childhood or adolescence) was significantly associated with the square root of the mean square of the differences between adjacent normal RR intervals for a period of time expressed in milliseconds (RMSSD) (ß = 8.86; 95%CI = 0.71;17.01), and the standard deviation of the instantaneous beat to beat variability (SD1) (ß = 6.21; 95%CI = 0.45;11.97). Sports practice at both stages of life was significantly associated with better SDNN (ß = 7.70; 95%CI = 1.16;14.23) and SD2 (ß = 10.18; 95%CI = 2.51;17.85). CONCLUSION: Early sports practice was associated with better CAM in adulthood, independently of the current physical activity level. Based on these findings, sports practice is encouraged from childhood and adolescence, for benefits to CAM in adult life.
RESUMEN
OBJECTIVE: To analyze the longitudinal relationship between overweight and hypertension in school children. METHODS: This cohort study enrolled children 6-8 years of age who were then prospectively followed up over a 24 months period with repeat assessments performed at an interval of 11-13 months. Information on participation in physical education classes in school, sports practice outside of school, and economic status were obtained through questionnaires answered by parents/guardians. The measurement of blood pressure, weight, height, and waist circumference was performed during the serial follow-up visits in school. RESULTS: The proportion of hypertension did not change significantly over the 24 months (7.1% to 8.2%; P = 0.690). However, children with overweight and obesity throughout the period, had a 198% [HR (95% CI) 2.98 (1.40, 6.35)] higher risk of having hypertension diagnosed during follow-up when compared to eutrophic children in the same period. CONCLUSION: The development trajectory of overweight and obesity in children aged 6-8 years was associated with hypertension.

BACKGROUND: The physical inactivity is a global health concern, so that recommendations on sufficient physical activity levels are elaborated worldwide, such as in Brazil. However, the Canadian 24-Hour Movement Guidelines were first in the world to consider time-specific recommendations for physical activity, sedentary behavior and sleep, which is still not developed for Latin-American population. The present study aimed to verify the adherence to Canadian 24-hour guidelines in a Brazilian inner city and to analyze its association with sociodemographic aspects. METHODS: A cross-sectional epidemiological study, with a sample composed by 250 adults (140 women), with a median age of 41.0 years. Objective measures of moderate-to-vigorous physical activity (MVPA) and sedentary behavior were collected by accelerometry. Sleep duration and sociodemographic aspects (ethnicity, gender, age, educational attainment and socioeconomic level) were obtained through a face-to-face questionnaire. Canadian 24-hour guidelines considered ≥ 150 min/week of MVPA, <8 h/day of sedentary behavior and daily sleep time between 7 and 9 h, being analyzed separately and in combination. Poisson regression with robust variance estimator was used to analyze the prevalence ratio (PR) of meeting the 24-hour guidelines according to the categories of sociodemographic variables, being performed by the software IBM SPSS version 25.0. RESULTS: The complete 24-hour guidelines were met only by 24.4% of sample (n = 61). Sedentary behavior was the most met guideline (88%), followed by MVPA (56.8%) and sleep (53.2%), without significant difference according to sex. When compared to elderly participants, those participants in younger groups (18-39 years and 40-59 years) were more likely to meet MVPA guideline (PR = 2.51 [95%CI = 1.47; 4.28] and PR = 2.60 [95%CI = 1.52; 4.45], respectively), as well as the combination of MVPA and sedentary behavior (PR = 1.98 [95%CI = 1.13; 3.44] and PR = 2.17 [95%CI = 1.25; 3.79], respectively) and MVPA with the sleep guideline (PR = 2.39 [95%CI = 1.09; 5.27] only for 18-39 years group). Men were more likely to meet MVPA guideline than women (PR = 1.29 [95%CI = 1.04; 1.59]). CONCLUSION: Younger aged and male adults were more likely to meet the Canadian 24-hour guidelines in a small Brazilian city. However, further studies with larger and representative samples of sociodemographic stratum are still needed.

BACKGROUND: Breast cancer survivors frequently present cardiac autonomic dysfunction. Physical activity (PA) has been associated with better cardiac autonomic modulation (CAM) in breast cancer survivors. OBJECTIVE: This study aimed to analyze the association between CAM and PA levels performed in different domains (work and occupation, sport and exercise, and leisure time and commuting) in breast cancer survivors. METHODS: This is a cross-sectional study with 99 breast cancer survivors (age, 55.3 ± 10.4 years). Cardiac autonomic modulation was assessed by heart rate variability, and PA levels at work and occupation, sport and exercise, and leisure time and commuting were assessed using the Baecke PA questionnaire. The sum of these 3 domains provided the total PA. The Mann-Whitney test was used to compare CAM between active and inactive women in different domains of PA. RESULTS: Cardiac autonomic modulation was similar between active and inactive women in the different domains ( P > .05). However, when considering the total PA, active breast cancer survivors presented higher SDNN (average standard deviation of all normal RR intervals) (20.0 ± 13.4 vs 28.8 ± 14.0; P = .008) and SD2 (standard deviation of the long-term intervals between consecutive heartbeats) indices (29.2 ± 17.3 vs 38.7 ± 19.9; P = .005) compared with their inactive counterparts. CONCLUSION: Breast cancer survivors with higher total PA presented better CAM compared with their less active peers. IMPLICATIONS FOR PRACTICE: The results of this study are promising and show the importance of increasing PA levels in different domains for the maintenance of cardiovascular health among breast cancer survivors.

BACKGROUND: The association of lifestyle habits of parents and of their children has been widely investigated as an important determinant for healthy habits in youth. Although parental sociodemographic characteristics are potential confounding factors in parent-child physical activity (PA) and sedentary behaviour (SB), it is still unclear whether these factors have a moderating role in this association. This study aimed to analyze the association of parent-child PA and SB according to parental sex and economic level in adolescents. METHODS: The study sample was made up of 1231 adolescents (15.6 ± 1.1 years, 58.2% of girls), 1202 mothers and 871 fathers. The leisure-time and commuting PA was assessed by the Baecke questionnaire, while sedentary behaviour (SB) was assessed according to hours per week of television viewing and computer use, by both adolescents and their parents. Economic status was analyzed using a questionnaire and classified as low, medium, and high. Linear models were used to assess the association of parent-child PA and SB in the different domains according to parental sex and economic level. RESULTS: Leisure time was associated between boys and their fathers in high (ß = 0.23, p = 0.044) and low economic classes (ß = 0.31, p < 0.001), and girls and their mothers in low economic class (ß = 0.38, p < 0.001). Commuting PA was associated between adolescents and both parents in low economic class (fathers ß = 0.21, p = 0.005; mothers (ß = 0.15, p = 0.020). TV time of boys was associated with TV time of fathers in low economic class (ß = 0.13, p = 0.022) and with TV time of mothers in medium economic class (ß = 0.13, p = 0.046). Among girls, TV time was associated with TV time of both parents only in low economic class (fathers ß = 0.28, p < 0.001; mothers ß = 0.25, p < 0.001). Computer use of girls was associated with computer use of fathers in high economic class (ß = 1.72, p = 0.043) and mothers in low economic class (ß = 0.57, p = 0.014), while no association was observed among boys. CONCLUSION: Economic status was shown to be an important moderator of the association between parent-child PA and SB in adolescents.
RESUMEN
BACKGROUND: Previous studies have quantified the current burden of diseases attributable to overweight in Chile. However, no study has estimated the attributable burden of overweight in the future. Herein, we estimated the potential impact of different trajectories in the prevalence of overweight on the incidence and mortality from non-communicable diseases (NCDs) in Chilean adults from 2019 to 2030. METHODS: A multistate life table modelling was used to estimate the business-as-usual (BAU: if the current rate of increase in BMI persist through the next 11 years; i.e., 0.4% per year from 2003 to 2017) and three counterfactual scenarios (1: the increase rate of overweight is reduced by half; 2: maintanance of the current prevalence of overweight; 3: the prevalence of overweight is reduced by 6.7%) over a 11-year simulation period for burden of NCDs attributable to overweight in Chilean adults aged 20 to 80 years. The model inputs included nationally representative data of body mass index, national official demographic records, NCDs from the Global Burden of Disease study in 2019, and relative risks from a published meta-analysis. RESULTS: If the current trends of increase in overweight are maintained in Chile, approximately, 669 thousand cases and 117 thousand deaths from NCDs will occur from 2020 to 2030. In case the increase rate of overweight is reduced by half during this period, around 7 thousand cases and 1.4 thousand deaths from NCDs would be prevented, while achieving no increase in the prevalence of overweight would avert 10 thousand cases and 2 thousand deaths. In the optimistic scenario of reducing the prevalence of overweight by 6.7% until 2030, approximately 25 thousand cases and 5 thousand deaths from NCDs would be prevented. CONCLUSION: We estimated that the number of NCDs cases and deaths that could be avoided by decreasing the prevalence of overweight in Chilean adults. Preventive programs aimed to reduce overweight may have a high impact on the future burden of NCDs in Chile.

OBJECTIVE: To identify and summarize the possible associations between screen time and low back pain in children and adolescents. DATA SOURCE: Systematic searches were performed in five electronic databases (Lilacs, Scielo, Scopus, PubMed and Web of Science) on 01/25/2021, complemented by manual searches in reference lists and on Google Scholar, looking for original scientific articles that included Brazilian observational studies; whose samples had children and/or adolescents aged between 6 and 19 years, without specific clinical conditions, and that presented analyses of associations between indicators of screen time and nonspecific low back pain, based on regression models. DATA SYNTHESIS: Nine cross-sectional studies whose samples had adolescents were included. Of the 18 analyses identified, nine reported risk relationships between the variables of interest. More specifically, risk associations were found in two studies that evaluated adolescents exposed to at least three hours using cell phone or tablet, and watching television per day. Also, instruments, cut-off points adopted, and screen equipment evaluated were diverse. CONCLUSIONS: Even though most of the risk associations were borderline from the statistical point of view, we found a higher frequency of risk associations between screen time and non-specific low back pain in adolescents exposed to screen time for at least three hours a day. In addition, further longitudinal studies with samples composed of children should be conducted across the country.

This study analyzed the influence of sedentary behavior (SB) on the association between dietary patterns and adiposity in community-dwelling adults. Eight hundred and forty-three adults (age: 56.5 ± 18.3 years) participated in this cross-sectional epidemiological study. Dietary patterns were evaluated using self-report questions regarding the weekly frequency of consumption of certain foods. Adiposity was determined using anthropometric measurements of weight, waist circumference, and height. SB was evaluated according to the time spent on screen devices. The usual physical activity level and socioeconomic status were considered confounding factors. Associations were determined using multivariate linear models with simultaneous adjustments for confounding variables. A statistical analysis indicated that fruit consumption was negatively related to the body mass index, regardless of the adjustment for SB domains. Red meat consumption was positively related to the body mass index, and fried food consumption was positively related to the waist-to-height ratio, regardless of the adjustment for SB domains. The consumption of fried food was positively associated with global and central adiposity after the adjustments for confounding factors and time spent on screen devices. We concluded that dietary habits are related to adiposity in adults. However, SB domains seem to influence the relationship between body adiposity and dietary habits, mainly regarding the consumption of fried foods.
RESUMEN
BACKGROUND: Sports practice in childhood and adolescence has been inversely related to the chances of developing cardiovascular risk factors (CRFs). However, it is not clear whether sports practice in childhood and adolescence could be inversely related to CRF in adult life. OBJECTIVES: This study aimed to analyze the association between early sports practice and cardiovascular risk factors in a randomized sample of community-dwelling adults. METHODS: For this, 265 adults aged ≥ 18 years composed the sample. Cardiovascular risk factors of obesity, central obesity, diabetes, dyslipidemia, and hypertension were collected. Early sports practice was retrospectively self-reported using an appropriate instrument. Total physical activity level was assessed by accelerometry. The association between early sports practice and cardiovascular risk factors in adulthood was analyzed by binary logistic regression, adjusted for sex, age, socioeconomic status, and moderate-to-vigorous physical activity. RESULTS: Early sports practice was observed in 56.2% of the sample. The prevalence of central obesity (31.5 vs. 50.0%; p = 0.003), diabetes (4.7% vs. 13.7%; p = 0.014), dyslipidemia (10.7% vs. 24.1%; p = 0.005), and hypertension (14.1% vs. 34.5%; p = 0.001) was lower in participants who reported early sports practice. Participants who reported early sports practice in childhood and adolescence were, respectively, 60% (OR = 0.40; 95% CI 0.19-0.82) and 59% (OR = 0.41; 95% CI 0.21-0.82) less likely to have hypertension in adult life when compared to those with no early sports practice, independently of sex, age, socioeconomic status, and habitual physical activity level in adulthood. CONCLUSION: Early sports practice in childhood and adolescence was a protective factor for hypertension in adulthood.
RESUMEN
Although breast cancer treatments reduce mortality, their adverse effects can increase depression which impacts one's quality of life (QoL). Physical activity (PA) seems to improve the QoL of breast cancer survivors (BCS). However, an unanswered question is the influence of PA on the QoL in BCS with depressive symptoms. Thus, we analyzed the influence of PA on the QoL in BCS with persistent depressive symptoms during 12 months of follow-up. The sample included 70 female BCS. Depression and QoL domains (i.e., functional capacity, physical limitations, body pain, general health status, vitality, social and emotional aspects, and mental health) were assessed at baseline and follow-up periods by the Hospital Anxiety and Depression Scale and SF-36, respectively. Habitual PA was assessed by Baecke's questionnaire. Our results indicate a prevalence of 17.1% of depressive symptoms. Non-depressives BCS improved their physical limitations and general health status domains over time, but there were no observed differences in depressive BCS. BCS with persistent depressive symptoms (baseline and follow-up) showed worse QoL scores than non-depressives in all domains, regardless of confounding factors. When adjusted for PA, the difference between BCS depressives and non-depressives lost its significance in the functional capacity domain. In conclusion, habitual PA practice positively influenced the functional capacity domain of the QoL in BCS.

Coronavirus disease 2019 (COVID-19) has detrimental multi-system consequences. Symptoms may appear during the acute phase of infection, but the literature on long-term recovery of young adults after mild to moderate infection is lacking. Heart rate variability (HRV) allows for the observation of autonomic nervous system (ANS) modulation post-SARS-CoV-2 infection. Since physical activity (PA) can help improve ANS modulation, investigating factors that can influence HRV outcomes after COVID-19 is essential to advancements in care and intervention strategies. Clinicians may use this research to aid in the development of non-medication interventions. At baseline, 18 control (CT) and 20 post-COVID-19 (PCOV) participants were observed where general anamnesis was performed, followed by HRV and PA assessment. Thus, 10 CT and 7 PCOV subjects returned for follow-up (FU) evaluation 6 weeks after complete immunization (two doses) and assessments were repeated. Over the follow-up period, a decrease in sympathetic (SNS) activity (mean heart rate: p = 0.0024, CI = -24.67--3.26; SNS index: p = 0.0068, CI = -2.50--0.32) and increase in parasympathetic (PNS) activity (mean RR: p = 0.0097, CI = 33.72-225.51; PNS index: p = 0.0091, CI = -0.20-1.47) were observed. At follow-up, HRV was not different between groups (p > 0.05). Additionally, no differences were observed in PA between moments and groups. This study provides evidence of ANS recovery after SARS-CoV-2 insult in young adults over a follow-up period, independent of changes in PA.

Objective To analyze the impact of sleep quality/duration on cardiac autonomic modulation on physically active adolescents with obesity. Materials and Methods The present cross-sectional study included 1,150 boys with a mean age of 16.6 ± 1.2 years. The assessment of cardiac functions included the frequency domain of heart rate variability (HRV; low frequency - LF; high frequency - HF; and the ratio between these bands -LF/HF -, defined as the sympathovagal balance), and each parameter was categorized as low / high . Physical activity levels and sleep quality/duration were obtained by questionnaires. Abdominal obesity was assessed and defined as waist circumference > 80 th percentile. Results Poor sleep quality resulted in lower HF (odds ratio [OR]: 1.8; 95% confidence interval [95%CI]: 1.01-3.21]) regardless of physical activity and abdominal obesity. Moreover, the study found no association between sleep duration and HRV parameters in adolescents. Conclusion Sleep quality, not sleep duration, reduces parasympathetic cardiac modulation apart from other factors such as physical activity and abdominal obesity in adolescents.

Resumo Objetivo: Identificar e sumarizar os dados sobre as possíveis associações entre o tempo de tela e a dor lombar em crianças e adolescentes. Fontes de dados: Buscas sistemáticas em cinco bases de dados eletrônicas (Lilacs, Scielo, Scopus, Pubmed e Web of Science), no dia 25/01/2021, complementadas por buscas manuais em listas de referências e no site Google Acadêmico, procurando por artigos científicos originais que comunicaram estudos observacionais brasileiros que envolveram amostras de crianças e/ou adolescentes entre 6 e 19 anos de idade, sem condições clínicas específicas e que apresentassem análises de associações entre indicadores do tempo de tela e dor lombar não específica, baseadas em modelos de regressão. Síntese dos dados: Nove estudos transversais foram incluídos, envolvendo amostras de adolescentes. Das 18 análises identificadas, 9 mostraram relações de risco entre as variáveis de interesse. Mais especificamente, verificaram-se associações de risco em dois estudos que avaliaram adolescentes expostos a, pelo menos, três horas diárias de celular, tablete e televisão. Também se observou diversidade entre instrumentos, pontos de corte adotados e equipamentos de tela avaliados. Conclusões: Mesmo que a maior parte das associações de risco tenha sido limítrofe, do ponto de vista estatístico, a presente síntese apresentou maior frequência de associações de risco entre o tempo de tela e a dor lombar não específica em adolescentes expostos ao tempo de tela por, pelo menos, três horas diárias. Complementarmente, recomenda-se que sejam conduzidos no país estudos longitudinais, com o envolvimento de crianças nas amostras.
RESUMEN
Extended periods of time on screen devices and sitting are the main activities that characterize sedentary behavior (SB), which negatively impacts the quality of life. This negative influence was demonstrated mainly by cross-sectional studies performed in high-income countries in which the effects of screen time on health-related quality of life (HRQoL) is not considered. Thus, we analyzed the association between the different domains of SB (i.e., subdomains of screen time-television, computer, cellphone) and the HRQoL in adults that live in Brazil during two years of follow-up. The sample included 331 adults. Subdomains of screen time (i.e., watching television, using computers, and cellphones) and of HRQoL (i.e., physical functioning, role-physical, bodily pain, general health, vitality, social functioning, role-emotional, mental health, and current health perception) were assessed by a structured questionnaire and SF-36, respectively. Our results indicate a significant increase in screen time during the two years of follow-up. Linear regression models indicated that although domains of SB were differently associated with HRQoL, in general, screen time was negatively associated with social functioning and positively associated with physical functioning during locomotion and activities of daily living (ADL), role-physical (i.e., physical issues during work and ADLs), and role-emotional (i.e., emotional issues during work and ADLs) after the two-year follow-up. In conclusion, screen time may positively or negatively influence some domains of HRQoL in adults.

Abstract Background Smoking is one of the leading causes of death, although there are several strategies for quitting smoking. Anxiety and depression can hinder this process. Objective To assess levels of anxiety and depression in smokers, adjusting the values for possible confounding variables such as sex, age, schooling, and socioeconomic status. Method Cross-sectional study, the sample included 444 subjects were assessed for smoking history, anxiety levels and depression by the Hospital Anxiety and Depression Scale and characterized according to the socioeconomic profile. Results An association was found between smoking and anxiety (p=0.003) and between smoking and depression (p≤ 0.001) even after adjustments for confounding factors (Smoking and anxiety: OR Sex: 2.01; OR Age: 2.56; OR Schooling: 2.25; OR Socioeconomic level: 2.26; Smoking and Depression: OR Sex: 4.80; OR Age: 3.13; OR Schooling: 1.82; OR Socioeconomic level: 1.81). Conclusion The study showed that smokers present high anxiety and depression.
RESUMEN
BACKGROUND: It is estimated that, worldwide, 9% of deaths occur as a result of insufficient physical activity (PA) practice. Practicing PA can prevent and/or reduce the deleterious effects of different types of diseases and can improve general health aspects related to health-related quality of life (HRQoL). PURPOSE: To analyze the relationship of different PA domains with different HRQoL domains over a two-year period. METHODS: This is an observational study with a two-year longitudinal design. The sample, composed of adults, was selected from a randomization of the streets of the different regions (north, south, east, west and center) covering individuals from all areas of the city. To assess the practice of PA, the Baecke questionnaire was used. The instrument Medical Outcomes Study SF-36-Item Short Form Health Survey was used to assess the HRQoL domains. Linear regression models were used to analyzed the association of different PA domains with changes in HRQoL. Multivariate statistical models were adjusted for gender, age, socioeconomic status, marital status, the respective PA score at baseline, smoking, body mass index, and morbidity. RESULTS: 331 adults were evaluated. There was a decrease in the practice of PA in the occupational domain and an increase in the leisure/locomotion domain. Regarding HRQoL, there was an increase in the scores of body pain and mental health, and a decrease in scores of general health, vitality, social aspects and emotional aspects. The PA practice in the occupational domain was inversely related to functional capacity (ß = - 7.2 [CI 95% - 13.0; - 1.4]). The practice of PA through sports in leisure time was positively associated with vitality (ß = 5.5 [CI 95% 0.2; 10.7]) and mental health (ß = 15.2 [CI 95% 6.8; 23.7]). PA practice during leisure and locomotion was inversely associated with functional capacity (ß = - 5.68 [CI 95% - 10.7; - 0.6]) and positively associated with vitality ß = 4.8 [CI 95% 0.8; 8.7]) and mental health (ß = 8.4 [CI 95% 2.0; 14.9]). The total PA practice was inversely associated with functional capacity (ß = - 3.8 [CI 95% - 6.5; - 1.2]) and positively associated with pain in the body (ß = 4.9 [CI 95% 0.3; 9.4]), vitality (ß = 2.9 [CI 95% 0.7; 5.0]) and mental health (ß = 5.7 [CI 95% 2.2; 9.2]). CONCLUSIONS: It is suggested that practicing PA continuously within a period of two years can positively affect some physical aspects and some mental aspects related to HRQoL, but not all of them. A strategy for public policy actions is to explore these variables by domain and thus detect the real needs and improvements that can be made for the population.

OBJECTIVE: To investigate the association of isotemporal substitution modeling (ISM) of time spent in sedentary activities with physical activity in different intensities on pain and disability of patients with chronic low back pain (LBP). DESIGN: Observational and cross-sectional study. Device-measured physical activity levels were assessed using an actigraph. Pain intensity was measured using the 11-point numeric rating scale, and disability was measured using the Roland Morris Disability Questionnaire. The ISM was used to estimate the theoretical substitution association of reallocating time from 1 exposure variable to an equal amount of time in another exposure variable while holding total activity time constant. SETTINGS: Outpatient physical therapy clinic. PARTICIPANTS: This study included data from 358 patients (N=358) with chronic LBP aged between 18 and 60 years. MAIN OUTCOME MEASURES: Pain and disability. RESULTS: Our results suggest that replacing 60 minutes of sedentary behavior with 60 minutes of vigorous activity in a week is significantly associated with a decrease in pain (ß=-1.67; 95% confidence interval [CI], -3.18 to -0.15). Additionally, replacing 60 minutes of light physical activity (ß=-1.67; 95% CI, -3.18 to -0.16) or moderate activity (ß=-1.67; 95% CI, -3.21 to -0.13) with the same amount of time of vigorous activity per week may also favorable reductions in pain. For the analysis of disability, no significant associations (P>.05) for disability in any of the isotemporal models were found. CONCLUSIONS: Our results showed that replacing 60 minutes of sedentary behavior with equal amounts of vigorous activity per week was associated with reductions in pain intensity. Similarly, replacing a light or moderate activities with vigorous activity was also associated with reductions in pain intensity. Finally, no significant associations were observed between time spent in sedentary activities with physical activity in different intensities for disability.
