Related-factors of social support for students' physical activity in a network perspective / Fatores relacionados ao suporte social para atividade física de estudantes em uma perspectiva de rede

This study investigates the relationship between social support and moderate to vigorous physical activity, as well as the possible relationships between social support and socioeconomic status, gender and body mass index. Cross-sectional study with a non-randomized sample of 71 students (boys and girls) aged 7 to 12 and their parents or legal guardians. Social support and socioeconomic status were assessed using validated questionnaires. Height and body mass measurements were used for the body mass index equation. Moderate to vigorous physical activity was measured by accelerometers. The associations between all variables were tested by a network analysis. Moderate to vigorous physical activity is negatively correlated with socioeconomic status, body mass index and a question from the social support questionnaire: "How many times in the last week have you watched your child be physically active?". We observed a positive correlation between moderate to vigorous physical activity with gender and a question from the social support questionnaire: "How many times in the last week did you provide transport for your child's physical activity?". Thus, moderate to vigorous physical ac-tivity has a negative correlation with socioeconomic status, body mass index and the variable "parents sometimes observe their child to be physically active", and parents who provide transportation for the child to practice physical activity. In future, it is import to consider the network analysis in the intervention studies to promote adolescents' physical activity

Este estudo investiga a relação entre suporte social e atividade física moderada-vigorosa, bem como as possíveis relações entre suporte social e nível socioeconômico, gênero e índice de massa corporal. Estudo transversal com amostra não randomizada de 71 escolares (meninos e meninas) de 7 a 12 anos e seus pais ou responsáveis. Apoio social e nível socioeconômico foram avaliados por meio de questionários validados. Medidas de altura e massa corporal foram usadas para a equação do índice de massa corporal. Atividade física moderada-vigorosa foi medida por acelerômetros. As associações entre todas as variáveis foram testadas por uma análise de rede. A atividade física moderada a vigorosa está negativamente correlacionada com o nível socioeconômico, índice de massa corporal e uma questão do questionário de apoio social: "Quantas vezes na última semana você observou seu filho ser fisicamente ativo?". Observou-se correlação positiva entre atividade física moderada-vigorosa com o gênero e uma questão do questionário de apoio social: "Quantas vezes na última semana você forneceu transporte para a atividade física de seu filho?". Assim, a atividade física moderada-vigorosa tem correlação negativa com o nível socioeconômico, índice de massa corporal e a variável "os pais às vezes observam que seu filho é fisicamente ativo, e pais que fornecem transporte para a criança praticar atividade física. No futuro, é importante considerar a análise de rede nos estudos de intervenção para promover a atividade física em adolescentes

Adherence to 24-hour movement guidelines in low-income Brazilian preschoolers and associations with demographic correlates.

BACKGROUND: The importance of movement behaviors for health is well known, although few studies have examined the adherence to movement guidelines in low-income preschoolers from a middle-income country, as Brazil. This study reports the proportion of preschoolers meeting the 24-hour movement guidelines and investigates its associations with demographic correlates in Brazilian low-income preschoolers. METHODS: Two hundred and seventy preschoolers (132 boys, means age = 3.97 ± 0.80) provided physical activity (PA) data (Actigraph wGT3X). Sleep duration, screen time, and social correlates were parent-reported. Preschoolers were classified as compliant/not compliant with the 24-hour movement guidelines. Relationships between compliance with movement behaviors guidelines and demographic correlates were calculated using a network analysis (Mplus 8.0; Rstudio). RESULTS: Preschoolers were active (273.52 ± 62.08 minutes/day of total PA), though moderate-to-vigorous physical activity (MVPA) time was below the guideline (58.68 ± 22.51 minutes/day); spent more than the recommended 60 minutes/day on screen time (169.91 ± 97.07 minutes/day); and slept less than 10 hours per night (9.44 ± 1.12 hours/day). Only 3% of the sample complied with the guidelines. PA showed the highest compliance (43%), compared to sleep duration (35%) and screen time (15%). Male sex was related to adherence to MVPA recommendations, while female sex, with adherence to total PA recommendations. Child's primary caregiver was the most important centrality indicator in the network. CONCLUSION: Only 3% of the assessed preschoolers are compliant with the 24-hour movement behaviors guidelines. Strategies to promote adherence to movement behaviors among low-income preschoolers should consider child's primary caregivers to support movement behaviors.

Beliefs and attitudes towards child epilepsy: A structural equation model.

PURPOSE: To analyze the possibly influencing factors of the beliefs and attitudes towards childhood epilepsy among users of the Family Health Strategy. METHODS: The participants were 300 users from three units of the Family Health Strategy in one city of northeastern Brazil. This primary health care service has a multidisciplinary team and operates close to the community, seeks to provide comprehensive care with actions to promote health, prevention, recovery, rehabilitation of diseases and frequent injuries in the community. Data were collected through a socioeconomic questionnaire and the Brazilian version of The Epilepsy Beliefs and Attitudes Scale - Adult Version, analyzed using descriptive statistics and structural equation analysis. RESULTS: Various associations were significant (p < 0.05), religion positively influences beliefs and attitudes (ß: 1.040; p: 0.044); an increase in educational level negatively influences beliefs and attitudes (ß: -0.723; p: 0.040); being the parent of a child negatively influences beliefs and attitudes (ß: 1.120; p: 0.043), but also positively influences beliefs (ß: -0.244; p: 0.028). CONCLUSION: This research contributed to identifying that having a religion, an increased educational level and being the parent of a child were factors that influence the beliefs and attitudes towards childhood epilepsy, aiming to contribute to a better implementation of actions directed to education in epilepsy.
