Lifestyle changes during the COVID-19 pandemic in Brazil: results from three consecutive cross-sectional web surveys.

Objective: The importance of a healthy lifestyle in preventing morbidity and mortality is well-established. The COVID-19 pandemic brought about significant lifestyle changes globally, but the extent of these changes in the Brazilian population remains unclear. The objective of this study was to evaluate changes in lifestyle among the Brazilian general population during the first year of the pandemic.

Self-reported social media use by adolescents in Brazil: a school-based survey.

Objective: Although there is a general perception that adolescent social media use is a global phenomenon, there is a scarcity of data on patterns and preferences of social media use among youth in low- and middle-income countries (LMICs). We here describe self-reported prevalence and perceived effects of social media use in a school-based sample of Brazilian adolescents.

Methods: We analyzed cross-sectional data on 7,113 adolescents aged 14 to 16 years enrolled at 101 public state schools between 2018 and 2019 in Porto Alegre, state of Rio Grande do Sul, Brazil.

Sleep disturbances, circadian activity, and nocturnal light exposure characterize high risk for and current depression in adolescence.

Study Objectives: Major depressive disorder (MDD) in adolescence is associated with irregularities in circadian rhythms and sleep. The characterization of such impairment may be critical to design effective interventions to prevent development of depression among adolescents. This study aimed to examine self-reported and actimetry-based circadian rhythms and sleep-wake behavior associated with current MDD and high risk (HR) for MDD among adolescents.

Social isolation as a core feature of adolescent depression: a qualitative study in Porto Alegre, Brazil.

Purpose: The goal of this study was to explore the perspectives of different stakeholders regarding the experiences of adolescent depression in Porto Alegre, Brazil.

Methods: We conducted 54 key-informant interviews with adolescents, parents, social workers, health workers, educators, and policy makers and two focus group discussions with 5 adolescents and 6 parents. Data were analysed using a framework approach and guided by the adolescents' personal narratives, with adult stakeholders' views supplementing these perspectives.

The Identifying Depression Early in Adolescence Risk Stratified Cohort (IDEA-RiSCo): Rationale, Methods, and Baseline Characteristics.

The characterization of adolescents at high risk for developing depression has traditionally relied on the presence or absence of single risk factors. More recently, the use of composite risk scores combining information from multiple variables has gained attention in prognostic research in the field of mental health. We previously developed a sociodemographic composite score to estimate the individual level probability of depression occurrence in adolescence, the Identifying Depression Early in Adolescence Risk Score (IDEA-RS).

Mental health information online: what we have learned from social media metrics in BuzzFeed's Mental Health Week.

Introduction: The Internet has seen rapid growth in the number of websites focusing on mental health content. Considering the increased need for access to accurate information about mental health treatment, it is important to understand the promotion of this information online.

Objective: To analyze BuzzFeed's Mental Health Week (BFMHW) interactions on its own website and in related social media platforms (Facebook, Twitter and YouTube) using metrics of information delivery in mental health topics.

Bipolar disorder affects behavior and social skills on the Internet.

Background: Bipolar disorder (BD) is a significant cause of functional, cognitive, and social impairment. However, classic studies of functioning and social skills have not investigated how BD may impact behavior on the Internet. Given that the digital age has been changing the way people communicate, this study aims to investigate the pattern of Internet use in patients with BD.
