Sports Participation from Childhood to Adolescence is Associated with Lower Body Dissatisfaction in Boys-A Sex-Specific Analysis.

OBJECTIVES: This study aimed to analyze the association between body dissatisfaction and sports participation from childhood to adolescence in a school-based sample of adolescents, according to sex. METHODS: A total of 1011 adolescents of 13.1 ± 2.3 years of age were evaluated. Body dissatisfaction was assessed by the Silhouettes Scale and sports participation for at least one consecutive year was retrospectively assessed by closed specific questions related to childhood and adolescence periods. Body mass index (BMI) and abdominal obesity were objectively measured. Habitual practice of physical activity (PA), socioeconomic status (SES), and ethnicity were assessed through questionnaires. RESULTS: Sports participation from childhood to adolescence was observed in 55.1% of boys and in 41.2% of girls. Boys with body dissatisfaction showed lower habitual PA in leisure time (Baecke score = 4.38 ± 2.27 vs. 5.15 ± 2.25, p < 0.05) and in total (Baecke score = 9.34 ± 2.64 vs. 9.96 ± 2.68, p < 0.05) than those who were satisfied. No differences were observed among girls. Sports participation from childhood to adolescence was associated with 42% less chance of having body dissatisfaction in boys (OR = 0.58 [95%CI = 0.36-0.94]). No significant association was observed among girls. CONCLUSIONS FOR PRACTICE: Sports participation from childhood to adolescence was negatively associated with body dissatisfaction in boys. The continuity of physical activity during youth may be an important modifiable factor to reduce body dissatisfaction.

Body size dissatisfaction associated with dietary pattern, overweight, and physical activity in adolescents: A cross-sectional study.

This study analyzed the association of body size dissatisfaction with body mass index, dietary pattern, and physical activity in adolescents. A sample of 1074 participants between 10 and 17 years of age was recruited. Body size dissatisfaction was assessed with the silhouettes' scale. Dietary pattern, physical activity, and socioeconomic status were assessed with questionnaires. Body mass index was measured objectively. The prevalence of body size dissatisfaction was 77.0%, where 29.8% desired to increase body size and 47.2% desired to decrease body size. Adolescents who desired to increase body size were more likely to consume vegetables and sweets and less likely to be in the highest quartile of physical activity than satisfied adolescents. Adolescents who desired to reduce body size were more likely to report lower fruit and vegetable consumption than satisfied adolescents. Health actions aiming to reduce body dissatisfaction in adolescents should address improvement in dietary pattern and physical activity engagement, considering that desires to increase or decrease body size were differently associated in this study.

Association of musculoskeletal pain with poor sleep quality in public school teachers.

BACKGROUND: Teachers perform repetitive movements all day, which can cause pain in body regions. This article analyzes the association of pain with sleep quality in this population. OBJECTIVE: The objective of the study was to analyze the relationship of musculoskeletal pain and sleep quality in teachers from public schools. METHODS: The sample consisted of 242 teachers, selected in a random process. Musculoskeletal pain and sleep quality were evaluated by using a questionnaire. The association between sleep quality and musculoskeletal pain was evaluated using the chi-square test. The magnitude of the associations was verified by Binary Logistic Regression, adjusted by sex, age, BMI, and socioeconomic status. RESULTS: Teachers with poor sleep quality presented higher body mass index (BMI) values when compared to teachers with good sleep quality (27.9 vs 26.0, p = 0.012). Teachers with poor sleep quality were approximately twice as likely to report thoracic pain (OR = 2.16[95% CI = 1.12-4.16]), wrist pain (OR = 3.28[95% CI = 1.18-9.07]), low back pain (OR = 3.09[95% CI = 1.29-7.41]), and ankle/foot pain (OR = 2.83[95% CI = 1.32-6.08]). CONCLUSIONS: Teachers with poor sleep quality were approximately twice as likely to present pain in several body parts. Our findings revealed that poor sleep quality was significantly associated with musculoskeletal pain in Brazilian teachers of public schools, regardless of confounding factors.

Sedentary behavior is more related with cardiovascular parameters in normal weight than overweight adolescents.

This study analyzed the relationship between sedentary behavior and cardiovascular parameters in normal weight and overweight adolescents. The sample included 449 boys and 555 girls with mean age of 13 years from public schools, which were divided into five geographical regions, with data collections performed in one selected school from each region. Sedentary behavior was assessed by screen time on TV, computer, videogame and cell phone/tablet, with good reliability in adolescents. Physical activity was assessed by Baecke's questionnaire, validated for adolescents. Measures of body weight, height and waist circumference were collected. Adolescents were classified as overweight or normal weight by cut-off points of body mass index for age and sex. Cardiovascular parameters were evaluated by oscillometric device and heart rate by specific monitor. Computer use was positively related to systolic blood pressure (SBP) (ß = 0.35; 95%CI = 0.07-0.62) and diastolic blood pressure (DBP) (ß = 0.25; 95%CI = 0.05-0.44) in normal weight but not in overweight adolescents. Similar results were observed for cell phone/tablet in SBP (ß = 0.46; 95%CI = 0.20-0.72) and DBP (ß = 0.36; 95%CI = 0.18-0.54), only for normal weight. The cluster of screen time was related to SBP in normal weight (ß = 0.44; 95%CI = 0.03-0.84) and overweight (ß = 0.60; 95%CI = 0.01-1.19). Screen time in computer and cell phone/tablet was more related to cardiovascular parameters in normal weight than overweight adolescents.

The relationship between physical activity intensity and domains with cardiac autonomic modulation in adults: An observational protocol study.

INTRODUCTION: Cardiac autonomic modulation is an important marker of cardiovascular health and the practice of physical activity is a fundamental tool for good maintenance or increments in this marker. However, it is not clear in the literature whether different intensities and different domains of physical activity are related in the same way to cardiac autonomic modulation. OBJECTIVES: This randomized epidemiologic study will examine the relationship between cardiac autonomic modulation and different intensities and domains of physical activity in a representative sample of adults. METHODS: The sample of study will consist of 252 subjects aged from 18 years and above. The sample will be randomized through census sectors in which the neighborhoods, streets, and houses will also be randomized. Cardiac autonomic modulation will be assessed by heart rate variability and the intensity (mild, moderate, intense) of physical activity will be evaluated by means of accelerometers, while the different domains of physical activity (physical activity at work, occupational activities) will be evaluated through a questionnaire. The relationship between cardiac autonomic modulation and different physical activity intensities, as well as the different domains will be analyzed by linear regression, considering a statistical significance of 5% and a 95% confidence interval. This research protocol is registered in ClinicalTrials.gov at number NCT03986879.

Physical activity of parents and of their children: a systematic review of Brazilian sample studies - Report Card Brazil / Atividade física de pais e filhos: uma revisão sistemática de estudos com amostras brasileiras - Report Card Brazil

Abstract The aim of this study was systematically review the researches in regard the association of PA of parents and the PA of their children. A literature search was performed in five databases (Medline, Embase, Cinahl, Lilacs and SciELO) using combined terms about youth, PA and social support, with restriction to publications with Brazilian sample and to English and Portuguese language. Thirteen studies were included in this review and was observed a positive association of parental PA and the PA of their children for the majority of the studies (n=11). Only two studies did not observed significant association between PA of parents and their children and, otherwise, it was not observed negative associations in the review. It was observed different associations according to the gender of both parents and children. This findings support the importance for the practice of PA by parents as encouragement for the practice of PA by their children among Brazilians. The strategies to promote the increase in practice of physical activity of children and adolescents of both genders may consider the social support as an important factor, especially in relation to the practice of PA of their parents.

Resumo O objetivo do presente estudo foi revisar sistematicamente estudos que analisaram a associação da prática de atividade física de pais e filhos. Foi realizada uma busca sistemática em cinco bases de dados (Medline, Embase, Cinahl, Lilacs e SciELO), por meio da combinação de termos sobre crianças e adolescentes, atividade física e suporte social, sendo restrita a estudos contendo amostras brasileiras e escritos em Inglês e/ou Português. Foram incluídos treze estudos na presente revisão e foi observada associação positiva da prática de atividade física de pais e filhos na maioria dos estudos (n=11). Somente dois estudos não observaram associação significativa da atividade física de pais e filhos, contudo não foram observadas associações negativas. Foram observadas diferentes associações de acordo com o gênero tanto dos pais quanto dos filhos. Estes achados ressaltam a importância da prática de atividade física dos pais como incentivo à prática de atividade física dos filhos em amostras brasileiras. Estratégias de promoção da prática de atividade física em crianças e adolescentes de ambos os sexos devem considerar o suporte social como um fator importante, especialmente a respeito da prática de atividade física dos pais.
