- Association of Cardiovascular Risk Factors between Adolescents and Their Parents Is Mitigated by Parental Physical Activity-A Cross-Sectional Study(2022) TEBAR, William R.; FERRARI, Gerson; MOTA, Jorge; ANTUNES, Ewerton P.; AGUILAR, Beatriz A. S.; BRAZO-SAYAVERA, Javier; CHRISTOFARO, Diego G. D.Introduction: It is hypothesized that children's habits can be modulated by their parent's lifestyle. However, it is still not established whether the relationship between cardiovascular risk factors (CVRF) in adolescents and their parents could be attenuated by parental physical activity levels. Objective: This study aimed to analyze the relationship of CVRF between adolescents and their parents according to parental physical activity level. Methods: A school-based sample of 1231 adolescents, 1202 mothers and 871 fathers were included (n = 3304). The CVRF assessed were overweight, hypertension, smoking and alcohol consumption. The parental physical activity level was assessed using a validated questionnaire, being classified into physically active and inactive parents. The statistical analysis considered all parents and stratification by physical activity level. Results: The prevalence of CVRF was higher in fathers than in mothers (70.6% vs. 54.9% for overweight, 23.3% vs. 19.7% for hypertension, 17.9% vs. 12.4% for smoking and 60.4% vs. 28.5% for alcohol consumption). Adolescents with active mothers showed lower prevalence of overweight (13.9% vs. 19.6%), while adolescents with active fathers showed higher prevalence of alcohol consumption (23.5% vs. 16.9%). The CVRF of both fathers and mothers were positively associated with CVRF of adolescents. However, the association of CVRF between adolescents and their parents was mitigated among active parents, while all the CVRF remained associated in physically inactive parents. Conclusion: The parental physical activity level seems to mitigate the association of CVRF between adolescents and their parents. The promotion of an active lifestyle at the family level can contribute to reduce CVRF among adolescents.
- Association between Different Domains of Sedentary Behavior and Health-Related Quality of Life in Adults: A Longitudinal Study(2022) SCARABOTTOLO, Catarina Covolo; TEBAR, William Rodrigues; GUERRA, Paulo Henrique Araujo; MARTINS, Clarice Maria de Lucena; FERRARI, Gerson; BERETTA, Victor Spiandor; CHRISTOFARO, Diego Giulliano DestroExtended 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.
- Sports practice, walking and biking are positively related to quality of life in adults: A cross-sectional study(2023) SILVA, Stefany Carolaine Bezerra; TEBAR, William Rodrigues; FERRARI, Gerson; LEMES, Italo Ribeiro; AGUILAR, Beatriz Anizia Santos; TEIXEIRA, Milena S.; MOTA, Jorge; RITTI-DIAS, Raphael Mendes; BERETTA, Victor Spiandor; CHRISTOFARO, Diego Giulliano DestroIntroduction: Physical activity (PA) has been associated with better quality of life (QoL). However, it is not clear whether this association is similar considering the different PA domains and independent of the intensity of PA practiced.Objective: To analyze the relationship between the time spent in PA in different domains [i.e., occupational, sports practice, walking and biking (through a combination of leisure and active transport)] and the QoL (i.e., physical functioning, role-physical, body pain, general health status, vitality, social functioning, role-emotional, and mental health) in adults.Methods: Two hundred and sixty-one adults with median age of 43.0 years (Interquartile range = 27.0-55.0 years) participated in this epidemiological study with a cross-sectional design. The sample included 261 adults QoL, PA domains, and PA intensities were assessed by the Short-Form Health Survey questionnaire (SF-36), the Baecke questionnaire, and using an accelerometer, respectively. Linear regressions adjusting for sex, age, socioeconomic status, body mass index, smoking status, alcohol consumption, and moderate to vigorous PA were used for analysis.Results: Occupational PA was negatively related to body pain domain of QoL (8 =-4.29; 95%CI =-7.27/-1.31). Sports practice was positively related to physical functioning (8 = 3.34 95%CI = 0.52/6.15), general health status (8 = 5.48; 95%CI = 2.20/8.76), vitality (8 = 5.39; 95%CI = 2.18/8.60), and mental health (8 = 3.47; 95%CI = 0.27/6.67) domains of QoL. Walking and biking were positively associated with vitality (8 = 4.48; 95%CI = 0.84/8.13) and mental health (8 = 4.21; 95%CI = 0.64/7.79) QoL domains.Conclusion: In conclusion, PA domains were associated with QoL differently. Regardless of PA intensity (measured objectively) and other factors, walking and biking were associated with indicators of mental health and vitality.
- Association between Leisure-Time and Commute Physical Activity and Pre-Diabetes and Diabetes in the Brazilian Longitudinal Study of Adult Health (ELSA-Brasil)(2023) SANCHEZ-MARTINEZ, Yuri; GOULART, Alessandra C.; ALMEIDA-PITITTO, Bianca de; DUNCAN, Bruce B.; SCHMIDT, Maria Ines; SANTOS, Itamar de Souza; LOTUFO, Paulo A.; TEBAR, William R.; BENSENOR, Isabela M.Background: Diabetes is an important public health problem due to its health impairments and high costs for health services. We analyzed the relationship between the domains of physical activity at leisure-time (LTPA) and at commuting (CPA) with diabetes and pre-diabetes in an ELSA-Brasil study. Methods: Data from 11,797 participants (52.5% women, 49.1 +/- 7.2 years) were analyzed. LTPA and CPA were measured using the International Physical Activity Questionnaire. Diabetes and pre-diabetes were defined by medical history, medication use to treat diabetes or blood glucose. Logistic regression models were performed to estimate the association between LTPA and CPA with diabetes and pre-diabetes after adjustment for sociodemographic and cardiovascular risk factors. Results: The prevalence of LTPA and CPA was 24.4% and 34%, respectively. Physically active participants at LTPA were less likely to have pre-diabetes (OR = 0.86 [95% CI = 0.77-0.95]) and diabetes (OR = 0.80 [95% CI = 0.69-0.93]), compared with inactive participants. No association between CPA and diabetes/pre-diabetes was observed. LTPA was inversely associated with diabetes among men (OR = 0.73 [95% CI = 0.60-0.89]), but was not associated among women. Women who were active (OR = 0.78 [95% CI = 0.67-0.90]) (OR = 0.79 [95% CI = 0.65-0.95]) at LTPA were less likely to have pre-diabetes, than inactive women. Conclusion: LTPA was inversely associated with diabetes and pre-diabetes in the ELSA-Brasil participants. A different behavior was observed between genders.
- Prevalence and association of compliance with the Canadian 24-hour movement guidelines with sociodemographic aspects in Brazilian adults: a cross-sectional epidemiological study(2024) DELFINO, Leandro Dragueta; TEBAR, William Rodrigues; CHRISTOFARO, Diego Giulliano DestroBackground 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.
- Association of Early Sports Participation With Sedentary Behavior in Community-Dwelling Adults-The Role of Sociodemographic Factors in a Retrospective Epidemiological Study(2023) TEBAR, William R.; BORGES, Luan O.; DELFINO, Leandro D.; MOTA, Jorge; RITTI-DIAS, Raphael M.; CHRISTOFARO, Diego G. D.Background: The role of sociodemographic factors in the association between early sports participation (ESP) and sedentary behavior is unclear. We analyzed the association of ESP with sedentary behavior and identified the influence of sociodemographic factors in adulthood. Methods: A sample of 264 community-dwelling adults was randomly assessed (42.6 [17.0] y old, 57.6% women). Sociodemographic factors (age, gender, and socioeconomic status) and ESP (retrospectively) were assessed by questionnaire. Sedentary behavior was measured by accelerometer and self-reported for domains identification. The association between ESP and sedentary behavior domains and sociodemographic factors was analyzed by Poisson regression and presented in prevalence ratio (PR). Sociodemographic factors were separately included as covariates to identify their role in the main association analysis. Results: The ESP prevalence was 56.4% (n = 149). ESP participants included a higher proportion of men (59.7% vs 20.0%), had a lower age (36.8 [15.3] vs 50.8 [15.9]), and included a smaller proportion of individuals with low socioeconomic status (24.8% vs 43.5%) compared with those without ESP. The ESP was inversely associated with older age (PR = 0.58, P < .001 for middle aged; PR = 0.34, P < .001 for older participants), female gender (PR = 0.79, P < .001), low socioeconomic status (PR = 0.63, P = .036), and TV watching (PR = 0.67, P = .011). ESP was associated with driving (PR = 1.50, P = .028), office/paper work (PR = 1.63, P = .012), and using a cellphone (PR = 1.60, P = .009). The age was the main confounding factor of association between ESP and sedentary behavior, followed by socioeconomic status. No mediation role was identified. Conclusion: The ESP was associated with mentally active behavior domains and inversely associated with mentally passive sedentary behavior domains, but this association was majorly affected by sociodemographic factors, mainly by age.
- Physical activity and sedentary behaviour of adolescents and their parents: a specific analysis by sex and socioeconomic status(2023) MESQUITA, Eduardo Duarte de Lima; TEBAR, William Rodrigues; CORREIA, Dayane Cristina Queiroz; GUICA, Juziane Teixeira; TORRES, Wesley; FERNANDES, Romulo Araujo; AGOSTINETE, Ricardo Ribeiro; CHRISTOFARO, Diego Giulliano DestroBackground 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 (beta = 0.23, p = 0.044) and low economic classes (beta = 0.31, p < 0.001), and girls and their mothers in low economic class (beta = 0.38, p < 0.001). Commuting PA was associated between adolescents and both parents in low economic class (fathers beta = 0.21, p = 0.005; mothers (beta = 0.15, p = 0.020). TV time of boys was associated with TV time of fathers in low economic class (beta = 0.13, p = 0.022) and with TV time of mothers in medium economic class (beta = 0.13, p = 0.046). Among girls, TV time was associated with TV time of both parents only in low economic class (fathers beta = 0.28, p < 0.001; mothers beta = 0.25, p < 0.001). Computer use of girls was associated with computer use of fathers in high economic class (beta = 1.72, p = 0.043) and mothers in low economic class (beta = 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.
