- 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.
- 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.
- Carotid intima-media thickness in adults with and without psoriasis - a nested case-control study from baseline data of ELSA-Brasil cohort(2023) TEBAR, William R.; SANTOS, Itamar de S.; MENEGHINI, Vandrize; BITTENCOURT, Marcio Sommer; LOTUFO, Paulo A.; BENSENOR, Isabela M.There is a lack of consensus about the association between psoriasis (PSO) and carotid intima-media thickness (cIMT) in literature, since previous studies considered dermatologic clinic patients or general population. This study aimed to compare cIMT levels according to PSO in a sample of 10,530 civil servants form the ELSA-Brasil cohort study and analyze its association with the disease. The PSO cases and disease duration were identified by medical diagnosis self-reported at study enrollment. A paired group was identified by propensity score matching among all the participants without PSO. Mean cIMT values were considered for continuous analysis while cIMT above 75th percentile was considered for categorical analysis. Multivariate conditional regression models were used to analyze association between cIMT and PSO diagnosis, by comparing PSO cases against paired controls and overall sample without disease. A total of n = 162 PSO cases were identified (1.54%) and no difference in cIMT values was observed between participants with PSO and overall sample or control group. PSO was not associated with linear increment of cIMT (vs. overall sample: beta = 0.003, p = 0.690; vs. matched controls: beta = 0.004, p = 0.633) neither with increased chance of having cIMT above 75th percentile (vs. overall sample: OR = 1.06, p = 0.777; vs. matched controls: OR = 1.19, p = 0.432; conditional regression: OR = 1.31, p = 0.254). There was no relationship between disease duration and cIMT (beta = 0.000, p = 0.627). Although no significant relationship between mild cases of psoriasis and cIMT was observed among a wide cohort of civil servants, longitudinal investigation about cIMT progression and severity of disease are still needed.
- 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 between cardiac autonomic modulation and sedentary behavior in breast cancer survivors: a 12-month cohort study(2022) PALMA, Mariana R.; TEBAR, William R.; VANDERLEI, Luiz Carlos M.; FREGONESI, Cristina E. P. T.; RIBEIRO, Fernanda E.; CALDEIRA, Daniela T.; RITTI-DIAS, Raphael M.; CHRISTOFARO, Diego G. D.Purpose This study aimed to analyze the longitudinal influence of sitting time (ST) on cardiac autonomic modulation (CAM) and resting heart rate (RHR) in a 12-month cohort of 67 breast cancer survivors. Methods CAM was assessed by heart rate variability with heart monitor which also assessed RHR, and ST was self-reported. The relationship between the variables was analyzed by the Pearson correlation and its magnitude by linear regression. Results At baseline, no associations were found between ST and CAM or RHR. In the delta analyses, a decrease in RMSSD, SD1, and HF(ms(2)) was associated with sitting time. At 12-month follow-up, there was an increase in the ST and a decrease in RHR. ST was negatively related with CAM (RMSSD, PNN50, and SD1), but no association was observed between ST and RHR. Conclusion The increase in ST was associated with worsening of CAM after 12-month follow-up. Promoting reduction in ST will be an important strategy against cardiovascular impairment in breast cancer survivors.
- Eight-year change in carotid intima-media thickness and associated risk factors in adults with and without psoriasis - the ELSA-Brasil cohort study(2023) TEBAR, W. R.; SANTOS, I. S.; MENEGHINI, V.; BITTENCOURT, M. S.; LOTUFO, P. A.; BENSENOR, I. M.The longitudinal association between psoriasis and carotid intima-media thickness (CIMT) has not yet been established. This study aimed do compare CIMT and its change (ACIMT) after an 8-year follow-up according to psoriasis diagnosis and the association with risk factors in the ELSA-Brasil study. Data from 7564 participants were analyzed (median age of 50.0 [44.0-57.0] years, 56.9% women). CIMT was assessed by ultrasound and ACIMT was calculated by subtracting baseline values from follow-up values. Psoriasis participants were identified by self-reported medical diagnosis (n=143) and compared with matched participants without disease (n=572) and with the entire sample without psoriasis (n=7421). Baseline CIMT explained the 8-year CIMT increase only in 36.9% among psoriasis participants and in B43.0% in participants without disease. CIMT was associated with age (6=0.002, P=0.002) and hypertension (6=0.029, P=0.034) in psoriasis participants. Among participants without psoriasis, CIMT was associated with age, male sex, low educational attainment, past smoking, obesity, diabetes, hypertension, and dyslipidemia (P<0.05). There was an inverse association of CIMT with private health insurance (6=-0.004, P=0.042) and White ethnicity (6=-0.006, P=0.004) in the entire sample without psoriasis but not in matched participants. Psoriasis participants showed an inverse association between ACIMT and diabetes (6=-0.214, P=0.011), while the entire sample without psoriasis showed an inverse association between ACIMT and age (6=-0.005, P<0.001), past smoking (6=-0.048, P=0.009), and hypertension (6=-0.048, P=0.009). In conclusion, psoriasis was not associated with CIMT after an 8-year follow-up. The inverse association of ACIMT with diabetes in psoriasis participants needs further clarification.
- 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.
