AI Article Synopsis
- The study investigates how common alexithymia is among patients with schizophrenia, finding a prevalence rate of 35%.
- Researchers used various databases to collect data from 17 studies involving 5,628 participants, assessing alexithymia with the TAS-20 scale.
- Factors such as being male, smoking, Asian ethnicity, case-control design, and divorce were linked to higher rates of alexithymia, but more high-quality research is needed to strengthen these findings.
Article Abstract
Objectives: This study aims to systematically evaluate the prevalence of alexithymia in patients with schizophrenia.
Methods: Computer searches were conducted in PubMed, PsycInfo, Web of Science, The Cochrane Library, EMBASE, China National Knowledge Infrastructure (CNKI), Wanfang Database, VIP Database, and China Biology Medicine (CBM) electronic databases to collect studies that utilized the TAS-20 scale as a measurement tool with clearly defined diagnostic criteria to determine the prevalence of alexithymia in patients with schizophrenia, from the inception of the databases to December 29, 2023. Two researchers independently screened the literature, extracted data, and evaluated the risk of bias in the included studies, followed by meta-analysis using Stata 16.0 software.
Results: A total of 17 studies with 5628 participants were included. The results of the meta-analysis showed that the prevalence of alexithymia in patients with schizophrenia was 35 % (95 % CI: 32-38 %). Subgroup analysis indicated that male gender, smoking, Asian ethnicity, case-control design and divorce were associated with higher rates of alexithymia (all P<0.05).
Conclusion: The prevalence of alexithymia in patients with schizophrenia is relatively high (35 %). However, due to limitations in the quality and quantity of included studies, further high-quality literature is needed to confirm the above conclusion.

Introduction: Athletes with concussions experience heterogeneous symptoms and clinical trajectories. Subclassification provides diagnostic clarity that may improve prognostication and individualized treatments.
Methods: We hypothesized that endophenotypes of adolescent athletes with concussions differ based on sex and time since injury.
Background: Childhood sleep problems are common and impact physical and emotional health. Prior work suggests that prenatal maternal depression and anxiety associate with disturbed child sleep in infancy. The current study evaluated whether these same associations extend to children at 3 years of age, and if so, whether the timing of symptoms in pregnancy is relevant.

Although previous studies have suggested an association between digital media use and health, detailed knowledge about how different types of digital media impact adolescent health is limited. This cross-sectional population-based study explored the relationship between time spent on various digital media and adolescents' self-rated general and mental health. The study included 3566 Swedish high school students aged 16-17 years.
