Article Synopsis
- Symptoms of generalized anxiety disorder (GAD) and social anxiety disorder (SAD) among adolescents are rising, prompting this study to explore how lifestyle factors affect their prevalence.
- The research analyzed data from over 130,000 Finnish students aged 14-18, using established questionnaires to identify anxiety symptoms and employing logistic regression models for analysis.
- Results indicated strong links between excessive internet use and reduced sleep with GAD, while SAD was associated with both heavy internet use and insufficient physical activity, highlighting the need for targeted health interventions.
Background: We examined exposure to adulthood traumatic life events (TLEs) and their associations with depression in women and men. Then we examined whether those associations are independent of exposure loading and vulnerability including familial confounding.
Methods: The fourth survey in 2011 of the population-based Finnish Twin Cohort had 8410 participants (45 % men, mean age 60 years).
Background: Psychotic-like experiences (PLEs) are common in clinical adolescent samples and form a continuum based on their frequency and intensity. PLEs can have harmful effects on both behaviour and affect.
Methods: Prevalence and subjective distress due to PLEs were assessed with the Prodromal Questionnaire-Brief (PQ-B) and depressive symptoms with the Beck Depression Inventory (BDI-21A) among adolescents ( = 399; 71.
Background: High levels of mental health problems among young people were reported during the COVID-19 pandemic, but studies of the post-pandemic period are scarce. We assessed mental health problems among Finnish youth before, during, and after the COVID-19 pandemic using nationwide population-based samples. Our aim was to examine in which direction the heightened levels of adolescent mental health problems have developed after the pandemic.

In this population-based study, these associations were examined from young adulthood to middle age.
Methods: Participants of a Finnish cohort study (N = 1955) were assessed at the ages of 22, 32, 42, and 52 using questionnaires covering daily smoking (yes/no) and the short 13-item Beck Depression Inventory.
