Screen use and sleep duration and quality at 15 years old: Cohort study.

Objective/background: The evidence on the association between screen use and sleep of adolescents is mainly based on studies about time watching television, with a few examining time using computers, videogames, and mobile devices. Our aim was to investigate the association between screen time for entertainment (watching TV, using computer, or playing games on tablets, smartphones, or videogame consoles) and sleep duration and self-reported sleep quality, among adolescents aged 15 years.

Methods: With data from the 2004 Pelotas Birth Cohort, sleep duration was assessed with questions extracted from the Munich Chronotype Questionnaire and quality was self-reported.

Construction and validation of the Oxford Neurodevelopment Assessment (OX-NDA) in 1-year-old Brazilian children.

Background: Over 250 million children under 5 years, globally, are at risk of developmental delay. Interventions during the first 2 years of life have enduring positive effects if children at risk are identified, using standardized assessments, within this window. However, identifying developmental delay during infancy is challenging and there are limited infant development assessments suitable for use in low- and middle-income (LMIC) settings.

Maternal perinatal depression and infant sleep problems at 1 year of age: Subjective and actigraphy data from a population-based birth cohort study.

This study used data from 2,222 mothers and infants participating in a population-based birth cohort to verify whether maternal depression in the perinatal period was associated with poor infant sleep. Mothers who scored ≥13 points on the Edinburgh Postnatal Depression Scale at 16-24 weeks of gestation and/or 3 months after delivery were considered perinatally depressed. The main outcome variable was poor infant sleep at 12 months of age, defined as >3 night wakings, nocturnal wakefulness >1 hr or total sleep duration <9 hr.

Validity of the Brief Infant Sleep Questionnaire (BISQ) in Brazilian children.

Objective: To investigate the validity of the Brief Infant Sleep Questionnaire (BISQ), in assessing sleep quality in childhood.

Methods: This was a validation study with children from the Pelotas 2015 Birth Cohort. BISQ was applied to mothers when their children were 3, 6, 12, and 24 months of age.

Effect of Parental Counseling on Infants' Healthy Sleep Habits in Brazil: A Randomized Clinical Trial.

Importance: Poor sleep during early childhood is associated with adverse outcomes, including obesity, cognitive impairment, and mental and behavioral disorders.

Objective: To assess the efficacy of an educational intervention in the promotion of nighttime sleep duration.

Design, Setting, And Participants: This single-blind, intent-to-treat randomized clinical trial included participants in Pelotas, Brazil, aged 3 months who were followed up until age 24 months.

Infant sleep hygiene counseling (sleep trial): protocol of a randomized controlled trial.

Background: Sleep problems in childhood have been found to be associated with memory and learning impairments, irritability, difficulties in mood modulation, attention and behavioral problems, hyperactivity and impulsivity. Short sleep duration has been found to be associated with overweight and obesity in childhood. This paper describes the protocol of a behavioral intervention planned to promote healthier sleep in infants.

Education in children's sleep hygiene: which approaches are effective? A systematic review.

Aim: To analyze the interventions aimed at the practice of sleep hygiene, as well as their applicability and effectiveness in the clinical scenario, so that they may be used by pediatricians and family physicians for parental advice.

Source Of Data: A search of the PubMed database was performed using the following descriptors: sleep hygiene OR sleep education AND children or school-aged. In the LILACS and SciELO databases, the descriptors in Portuguese were: higiene E sono, educação E sono, educação E sono E crianças, e higiene E sono E infância, with no limitations of the publication period.

Prevalence of Helicobacter pylori infection and associated factors among adults in Southern Brazil: a population-based cross-sectional study.

Background: Helicobacter pylori (Hp) infection is associated with several upper gastrointestinal disorders. Local data on the epidemiology of the infection are scarce in Brazil. The purpose of this study is to measure the prevalence rate and to explore the associated factors among the adult population living in Pelotas, a southern Brazilian city.
