Exposure to Smartphones and Tablets, Physical Activity and Sleep in Children From 5 to 10 Years Old: A Systematic Review and Meta-Analysis.

Objective: To conduct a systematic review and meta-analysis to verify the association between smartphone/tablet exposure and physical activity sleep in children from 5 to 10 years old. Data Source: This study followed the guidelines of PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-Analyses) and included studies that met eligibility criteria based on the "PECO" strategy: participants (children from 5 to 10 years old), exposure (smartphone and tablet use), and outcome (physical activity and sleep).

Study Inclusion And Exclusion Criteria: The inclusion criteria were observational studies published in indexed scientific journals and written in Portuguese, English, and Spanish that verified the association of exposure to smartphones/tablets with physical activity and sleep in children aged 5 to 10 years of both sexes.

Do patients with obesity undergoing bariatric surgery modify their objectively measured physical activity? A systematic review and meta-analysis.

Background: Obesity is a chronic disease associated with adverse outcomes and its prevalence is increasing, which makes it a concern. One of the obesity treatment options is bariatric surgery, which effectively reduces calorie absorption and total body mass, but its effects on physical activity (PA) levels need to be clarified, considering the protective effect of the PA against cardiovascular disease, independently of the weight loss alone.

Objectives: To carry out a systematic review and meta-analysis of observational studies that evaluated PA in pre- and post-bariatric surgery periods through objective evaluation.

Clustering of health risk behaviors in pregnant individuals: Data from the Brazilian risk factor surveillance system for non-communicable chronic diseases.

Objective: To investigate the clustering of health risk behaviors (HRB) and its association with demographics, physical exercise, overweight, perception of health, and diseases in Brazilian pregnant people.

Study Design: This is a cross-sectional study using data from the Risk Factor Surveillance System for Non-communicable Chronic Diseases by Telephone Survey (VIGITEL), the main health survey in Brazil.

Methods: We used data on fruit and vegetable consumption, TV time, tobacco, and alcohol abuse in individuals who reported being pregnant (n = 4553).

Factors associated with Alzheimer's disease prevalence and mortality in Brazil-An ecological study.

A few epidemiological studies are evaluating the prevalence and mortality rates of Alzheimer's disease, with no one using a nationwide sample of Brazilian elderlies. This study aims to calculate the prevalence of Alzheimer's disease and investigate possible associations with sociodemographic and lifestyle factors and the presence of diseases non-communicable, and the prevalence and mortality for all Brazilian state capitals. This is an ecological design study made with secondary public data provided by the Ministry of Health.

Is Binge Drinking Associated With Specific Types of Exercise and Free Time Sports? A Pooled Analysis With 718,147 Adults.

Objective: To verify the association between exercise and free time sport types and binge drinking in a large sample of adults.

Methods: Data of 718,147 adults from the "Surveillance of Risk and Protection Factors for Chronic Diseases by Telephone Survey" were used. We described the demographic and behavioral variables, and negative binomial regression analyzed the association between exercise and free time sport types and binge drinking adjusted by demographics variables, body mass index status, and television time.

The Relationship between Physical Activity, Sleep Quality, and Stress: A Study of Teachers during the COVID-19 Pandemic.

The COVID-19 pandemic prompted chaotic changes in the daily lives of K-12 teachers, resulting in increased stress and other mental health problems. Limited evidence regarding the relationship between physical activity, sleep, and perceived stress among teachers during the COVID-19 pandemic exists. Therefore, the purpose of this study was to investigate the association between physical activity, sleep quality, and perceived psychological stress among teachers during the COVID-19 pandemic.

Age and Sex-Related Associations between Marital Status, Physical Activity and TV Time.

Marital status mediates an association between physical activity (PA) and TV time with health outcomes. However, population-based studies have revealed that the health effect of marriage or divorce is age-dependent and differs between women and men. The study aimed to identify the age and sex-related associations between marital status with PA and TV time.

Female students are the most psychologically affected by the COVID-19 outbreak: a case study in an academic community in Brazil.

Objective: The study evaluates psychological responses to the COVID-19 outbreak in the students, professors, and staff due to the social distancing and transition of the classroom activities through online learning.

Methods: 518 participants from a University community in Brazil answered an online survey with questions related to demographic data, psychological responses, and preventive measures. Absolute and relative frequencies described the sample, Chi-square and z-test tested associations between the variables, adopting p<0.

Calibration of the Online Youth Activity Profile Assessment for School-Based Applications.

A balance between the feasibility and validity of measures is an important consideration for physical activity research - particularly in school-based research with youth. The present study extends previously tested calibration methods to develop and test new equations for an online version of the Youth Activity Profile (YAP) tool, a self-report tool designed for school applications. Data were collected across different regions and seasons to develop more robust, generalizable equations.

IMPACT OF PHYSICAL ACTIVITY CORRELATES IN THE ISOLATED AND COMBINED PRESENCE OF INSUFFICIENT LEVEL OF PHYSICAL ACTIVITY AND HIGH SCREEN TIME AMONG ADOLESCENTS.

Objective: To identify the impact of physical activity correlates with the isolated and combined presence of insufficient physical activity and high screen time among adolescents.

Methods: A cross-sectional representative study was carried out with a sample of 786 adolescents (16.0±1.

Step-Count Guidelines for Children and Adolescents: A Systematic Review.

Background: The aim of this systematic review was to identify the most optimal step-count cutoff for children and adolescents (5-19 years old) among guidelines currently available in the literature.

Methods: The databases searched were PubMed, SportDiscus, Science Direct, Web of Science and LILACS. Studies were categorized into Health Cohort studies or Physical Activity (PA) Cohort studies according to the reference standard used.
