Impact of Environmental Noise and Sleep Health on Pediatric Hypertension Incidence: ABCD Study.

Background: Pediatric hypertension is linked to environmental factors like neighborhood noise disrupting sleep, which is crucial for health. The specific interaction between noise and sleep health in causing hypertension still needs to be explored.

Methods And Results: We analyzed data from 3320 participants of the ABCD (Adolescent Brain Cognitive Development) study, recruited across 21 US cities and monitored from 2018 to 2020 through 2020 to 2022.

Can Food and Beverage Advertising Questionnaire Predict Overweight and Obesity in Children and Adolescents from Low- and Middle-Income Countries?

Information about the reliability and validity of questionnaires in low- and middle-income countries remains scarce. To test the reliability and predictive validity of a food and beverage marketing/advertising questionnaire for South American children and adolescents. A sample of 330 children (3-10 years old) and 215 adolescents (11-18 years old) was included from seven South American cities: Buenos Aires, Lima, Medellín, Montevideo, Santiago, Sao Paulo, and Teresina.

Evaluation of the Validity of a Food Frequency Questionnaire and 24-Hour Dietary Recall to Assess Dietary Iron Intake in Children and Adolescents from the South American Youth/Child Cardiovascular and Environmental Study.

Background: A food frequency questionnaire (FFQ) for South American children and adolescents was developed, but its validity for assessing dietary iron intake has not been evaluated.

Objective: To evaluate the validity of the FFQ and 24-hour dietary recalls (24h-DR) for assessing dietary iron intake in children and adolescents.

Design: The South American Youth/Child Cardiovascular and Environmental study is a multicenter observational study, conducted in five South American cities: Buenos Aires (Argentina), Lima (Peru), Medellin (Colombia), Sao Paulo, and Teresina (Brazil).

Comparative assessment of mortality risk factors between admission and follow-up models among patients hospitalized with COVID-19.

Objectives: This study aimed to compare differences in mortality risk factors between admission and follow-up incorporated models.

Methods: A retrospective cohort study of 524 patients with confirmed COVID-19 infection admitted to a tertiary medical center in São Paulo, Brazil from 13 March to 30 April 2020. Data were collected on admission, and the third, eighth and fourteenth days of hospitalization.

Reliability and validity of body weight and body image perception in children and adolescents from the South American Youth/Child Cardiovascular and Environmental (SAYCARE) Study.

Objective: To assess the reliability and validity of body weight (BW) and body image (BI) perception reported by parents (in children) and by adolescents in a South American population.

Design: Cross-sectional study. BW perception was evaluated by the question, 'Do you think you/your child are/is: severely wasted, wasted, normal weight, overweight, obese?' BI perception was evaluated using the Gardner scale.

Associations between REV-ERBα, sleep duration and body mass index in European adolescents.

Background/objective: Although the REV-ERBα is considered an important regulator of both clock function and metabolism, its relationship with sleep duration and obesity is less clear. The objective of this study was to examine the association between the REV-ERBα clock gene and two outcomes - sleep duration and body mass index (BMI) - in European adolescents.

Methods: A sample of 831 adolescents (392 boys) aged 11.

Agreement Between Standard Body Composition Methods to Estimate Percentage of Body Fat in Young Male Athletes.

Purpose: To examine the intermethods agreement of dual-energy X-ray absorptiometry (DXA) and foot-to-foot bioelectrical impedance analysis (BIA) to assess the percentage of body fat (%BF) in young male athletes using air-displacement plethysmography (ADP) as the reference method.

Methods: Standard measurement protocols were carried out in 104 athletes (40 swimmers, 37 footballers, and 27 cyclists, aged 12-14 y).

Results: Age-adjusted %BF ADP and %BF BIA were significantly higher in swimmers than footballers.

Validity and reliability of sleep time questionnaires in children and adolescents: A systematic review and meta-analysis.

Sleep duration has been associated with several health outcomes in children and adolescents. As an extensive number of questionnaires are currently used to investigate sleep schedule or sleep time, we performed a systematic review of criterion validation of sleep time questionnaires for children and adolescents, considering accelerometers as the reference method. We found a strong correlation between questionnaires and accelerometers for weeknights and a moderate correlation for weekend nights.

Dietary animal and plant protein intakes and their associations with obesity and cardio-metabolic indicators in European adolescents: the HELENA cross-sectional study.

Background: Previous studies suggest that dietary protein might play a beneficial role in combating obesity and its related chronic diseases. Total, animal and plant protein intakes and their associations with anthropometry and serum biomarkers in European adolescents using one standardised methodology across European countries are not well documented.

Objectives: To evaluate total, animal and plant protein intakes in European adolescents stratified by gender and age, and to investigate their associations with cardio-metabolic indicators (anthropometry and biomarkers).

Prevalence of cardiovascular risk factors, the association with socioeconomic variables in adolescents from low-income region.

Objectives: To estimate the prevalence of obesity, overweight, abdominal obesity and high blood pressure in a sample of adolescents from a low-income city in Brazil and to estimate the relationship with the socioeconomic status of the family, the education level of the family provider and the type of school.

Methods: This cross-sectional study randomly sampled 1,014 adolescents (54.8% girls), between 14-19 years of age, attending high school from Imperatriz (MA).

Does administering albumin to postoperative gastroschisis patients improve outcome?

Objectives: Newborns who undergo surgery for gastroschisis correction may present with oliguria, anasarca, prolonged postoperative ileus, and infection. New postoperative therapeutic procedures were tested with the objective of improving postoperative outcome.

Patients And Methods: One hundred thirty-six newborns participated in one of two phases.
