Objective: To analyze how the journalistic media has described the issues of quality of life (QoL), physical activity (PA) and mental health (MH) of adolescents during the COVID-19 pandemic.
Methods: This is a descriptive and qualitative study that used content analysis. Sixty-two journalistic publications were analyzed from a total of 8211 published by the most read newspapers in each Brazilian region between December 2019 and August 2021.
Single breath counting technique to assess pulmonary function: a systematic review and meta-analysis.
J Breath Res
November 2023
Pulmonary function is usually assessed by measuring Vital Capacity (VC) using equipment such as a spirometer or ventilometer, but these are not always available to the population, as they are relatively expensive tests, difficult to transport and require trained professionals. However, the single breath counting technique (SBCT) appears as a possible alternative to respiratory function tests, to help in the pathophysiological understanding of lung diseases. The objective is to verify the applicability of the SBCT as a parameter for evaluating VC.

- The study investigates how cardiac autonomic modulation is affected in young asthmatics during eucapnic voluntary hyperpnea (EVH), especially focusing on those with and without exercise-induced bronchoconstriction (EIB).
- It involved 54 asthmatic participants aged 10 to 19, measuring their lung function (FEV) and heart rate variability (HRV) before and after the EVH test.
- Findings revealed that asthmatics with EIB had a delayed increase in parasympathetic activity after EVH compared to those without EIB, suggesting differences in autonomic nervous system responses related to their condition.
Background: To determine whether biological and sociodemographic factors at birth and current factors are associated with insufficient physical activity during leisure among Brazilian adolescents.
Methods: A school-based cross-sectional study with national coverage was conducted involving Brazilian adolescents 12 to 17 years of age in municipalities with more than 100 thousand residents. The sample consisted of 74,589 adolescents who participated in the Study of Cardiovascular Risk in Adolescents.

- The study examined how well Peak Nasal Inspiratory Flow (PNIF) and Peak Nasal Expiratory Flow (PNEF) can predict nasal obstruction symptoms in individuals.
- In a sample of 131 participants, those without allergic rhinitis had higher PNIF and PNEF values compared to those with symptoms.
- The research found specific threshold values for PNIF and PNEF that indicate potential nasal obstruction, suggesting these measures can help assess and screen for nasal problems effectively.
Objective: To investigate context of overweight adolescents from the semiarid and rural areas of Pernambuco, considering the multifactorial nature of the determinants of being overweight, and the food and nutritional insecurity conditions of the region.
Methods: A population based cross-sectional study was conducted from September to October 2015. The nutritional status of adolescents was assessed by body mass index (BMI) and classified by the BMI/Age indicator, according to sex.
Objective: To assess the level of physical activity in asthmatics in comparison with non-asthmatics in a population study.
Methods: Cross-sectional study with 13 to 14-year-old adolescents who participated in the International Study of Asthma and Allergies in Childhood (ISAAC). The subjects were classified into three groups: individuals with active asthma, individuals diagnosed with asthma, and respiratory asymptomatic individuals.
Objective: To identify the prevalence of iron-deficiency anemia and associated factors in women at reproductive age in the city of Vitoria de Santo Antão, Pernambuco.
Methods: Cross-sectional study with a representative sample of 322 women aged between 15 and 49 years. Anemia was diagnosed by measuring hemoglobin below 12 g/dL.
Background: Exercise-induced bronchospasm (EIB) is the bronchial narrowing that occurs after intense exercise in a significant number of asthmatics and in some non-asthmatics. This study aims to evaluate the occurrence of EIB in adolescents with asthma, rhinitis and respiratory asymptomatics in a hot and dry climate.
Research Design And Methods: This is a cross-sectional study based on an epidemiological study that evaluated the prevalence of asthma in schoolchildren in a semi-arid zone of Brazil.
Objective:: To describe the prevalence of short stature among children of Karapotó ethnic background.
Methods:: Cross-sectional, population-based study that included children between 6 and 59 months of age from the Plak-Ô native village and the Terra Nova settlement, São Sebastião, Alagoas, carried out between 2008 and 2009. Short stature was evaluated by the Height/Ageindex, using as cutoff z score≤−2.
Objective:: To identify cutoff points of the Homeostatic Model Assessment for Insulin Resistance (HOMA-IR) index established for adolescents and discuss their applicability for the diagnosis of insulin resistance in Brazilian adolescents.
Data Source:: A systematic review was performed in the PubMed, Lilacs and SciELO databases, using the following descriptors: "adolescents", "insulin resistance" and "Receiver Operating Characteristics Curve". Original articles carried out with adolescents published between 2005 and 2015 in Portuguese, English or Spanish languages, which included the statistical analysis using Receiver Operating Characteristics Curve to determine the index cutoff (HOMA-IR) were included.
Article Synopsis
- The study evaluated the physical activity levels and quality of life among ICU professionals using specific questionnaires to gather data.
- Approximately 50.89% of the 59 participants were classified as active, with nursing technicians being the most active at 60.6%.
- Active ICU professionals reported better quality of life, particularly in physical limitations, social aspects, and mental health, likely due to having lower work hours and more free time to exercise.
Objective:: To evaluate the nutritional status of schoolchildren, resident in a semiarid region in the Northeastern Brazil.
Methods:: This is a cross-sectional study, involving 860 children and adolescents aged from 5-19 years-old, enrolled in three public schools in the county. The selection of schools was non-probabilistic type and unintentional.
Objective: To assess calcium, protein and sodium intake, of children that attend public day-care centers and to compare it with the recommended one.
Methods: Cross-sectional descriptive study in seven public day care centers of São Paulo city, Southeast Brazil, which enrolled 366 children between 12 and 36 months of age. The data collection occurred between September and December 2010.
The objective of this study was to determine the prevalence of anemia and vitamin A deficiency and to analyze the association of food insecurity with hemoglobin levels and serum retinol in children under 5 years of age. This was a cross-sectional study with 501 families from Gameleira and 458 families from São João do Tigre. Food insecurity was assessed according to the Brazilian Food Insecurity Scale.
