RESUMO

Objetiva-se verificar se a relação tempo de tela (TT) e aptidão cardiorrespiratória (APCR) está associada com as alterações na pressão arterial (PA) em crianças e adolescentes. Trata-se de um estudo transversal com 2166 escolares, de ambos os sexos, com idades entre 6 e 17 anos. Foi aplicado um questionário com questões referentes ao estilo de vida, para verificação do TT (computador, vídeo game e TV), que foi computado em horas e classificado como elevado TT (≥ 2 horas diárias) e baixo TT (< 2 horas diárias). Para avaliação da PA, foi considerada alterada nos casos limítrofes e hipertensão, para pressão arterial sistólica (PAS) e diastólica (PAD). A APCR foi avaliada por meio do teste de corrida/caminhada de 6 minutos. Para a análise dos dados foi utilizada a estatística descritiva, por meio da frequência e percentual, para caracterizar os sujeitos, sendo aplicada a regressão de Poisson para obtenção dos valores de razão de prevalência (RP) e intervalos de confiança (IC), na relação da variável preditora (relação TT/APCR) com o desfecho (PA alterada). Como resultados encontrados, observou-se que 24,8% dos escolares apresentam elevado TT e baixos níveis de APCR. Em relação à PA, 18,7% dos indivíduos estiveram com a PAS alterada e 15,4% com PAD alterada. A associação entre PA alterada e a relação TT/APCR somente foi evidenciada para PAS entre as meninas. Nesse sentido, observou-se que a alteração na PAS é mais prevalente entre os escolares com baixo TT/inapto (RP: 1,07; p=0,008) e com elevado TT/inapto (RP: 1,06; p=0,029). Conclui-se que as meninas com baixos níveis de APCR, independente do TT, apresentam maior prevalência de PAS alterada....(AU)

This study aims to verify if the relation of screen time (ST) and cardiorespiratory fitness (CRF) is associated with the presence of alteration in blood pressure (BP) in children and adolescents. This is a cross-sectional study with 2166 students, aged 6 to 17 years. A questionnaire with questions related to lifestyle was used to verify the ST (computer, video game and TV), which was computed in hours and classified as high ST (≥ 2 hours daily) and low ST (<2 hours daily). For BP evaluation, borderline cases and hypertension were considered as altered BP, for systolic (SBP) and diastolic (DBP) pressure. CRF was assessed by the 6-minute walk/run test. For data analysis, descriptive statistics were used, by means of frequency and percentage, to characterize the subjects, and Poisson regression was used to obtain the prevalence ratio (PR) and confidence intervals (CI) values, in relation to the predictor variable ST/CRF) with the outcome (PA altered). As results, we observed that 24.8% of the students present high ST and low levels of CRF. In relation to BP, 18.7% and 15.4% of subjects had altered SBP and DBP, respectively. The association between altered BP and the ST/CRF ratio was only evidenced for SBP among girls. In this sense, it was observed that the change in SBP is more prevalent among schoolchildren with low ST/inapt (PR: 1.07, p = 0.008) and with high ST/inapt (PR: 1.06, p = 0.029). It is concluded that girls with low CRF levels, regardless of ST, present a higher prevalence of altered SBP....(AU)

RESUMO

OBJECTIVE: The prevalence of overweight and obesity is gradually increasing in both developed and developing countries. Obesity, for instance, can present multifactorial causes that interact with each other. Among the important factors, parental obesity plays a prominent role in the onset of obesity during childhood and teenage years through genetics and ambient aspects. This study aims to verify the possible existence of an association between overweight/obesity of schoolchildren and cardiovascular risk (CVR) factors for their parents. SUBJETCS AND METHODS: For this purpose, a cross-sectional study was conducted with a sample of 1,243 children and adolescents, aged between 7 and 17. Out of the total number of participants, 563 (45.3%) were boys who were selected across 19 schools in the urban and rural areas of Santa Cruz do Sul, Rio Grande do Sul (Brazil). The overweight/obesity status of the schoolchildren was evaluated through their body mass index (BMI). Additionally, a self-reference questionnaire was employed to measure their parents' CVR. RESULTS: The results of this study revealed that students with overweight/obesity have a higher probability of having a father with hypertension (OR = 1.49; p = 0.038) and obesity (OR = 2.36; p = 0.002) and a mother with obesity (OR = 1.72; p = 0.016). CONCLUSION: To conclude, this study confirms a relationship between overweight/obesity of schoolchildren with CVR for their parents.

RESUMO

INTRODUCTION AND OBJECTIVE: Pediatric hypertension has increased in the last decade, and it is thus crucial to identify the factors associated with the development of high blood pressure (BP) and other cardiovascular disorders. The aim of this study was to determine whether there is an association between high BP and sociodemographic and biochemical factors in schoolchildren. METHODS: This cross-sectional study included 1201 children and adolescents, between seven and 17 years old, of both sexes. The sociodemographic data analyzed were gender, age, school system and socioeconomic status. Among biochemical indicators, blood glucose, triglycerides, total cholesterol, HDL-cholesterol (HDL-C) and LDL-cholesterol (LDL-C) were assessed. In the analysis of BP, schoolchildren were classified as normal, borderline or hypertensive. Associations were tested using Poisson regression through prevalence ratios (PR). RESULTS: High BP was identified in 16.2% of the students. In females, the prevalence of high BP was 7% lower than in males (p=0.001), but was higher among adolescents (PR: 1.11, p<0.001) and schoolchildren in the state school system (PR: 1.05; p=0.013). Concerning biochemical indicators, BP change was associated with pre-diabetes (PR: 1.09; p=0.001) and borderline HDL-C (PR: 1.09; p=0.007). CONCLUSION: Among the sociodemographic factors associated with high BP are male gender, adolescence and attending the state education system. This condition was also associated with pre-diabetes and borderline HDL-C.
