Article Abstract
Background: Research increasingly demonstrates a positive association between Internet Gaming Disorder (IGD) and conduct problems among adolescents. However, longitudinal data are limited, and the mediating mechanisms remain unclear. This study aimed to examine the predictive effect of IGD on conduct problems and explore the mediating role of impaired sleep quality.
Method: A cohort of 20,137 Chinese seventh- and tenth-grade students was recruited and assessed at three time points: November 2020 (T1), 2021 (T2), and 2022 (T3). IGD, conduct problems, and impaired sleep quality were measured using the Internet Gaming Disorder Scale Short Form, the Strengths and Difficulties Questionnaire, and the Pittsburgh Sleep Quality Index, respectively. Mediation analyses were conducted to evaluate the direct and indirect effect of IGD on conduct problems, with subgroup analyses based on sex and developmental stage.
Results: IGD was found to be an independent risk factor for conduct problems both cross-sectionally and longitudinally. Impaired sleep quality partially mediated the relationship between IGD and conduct problems, accounting for approximately 17.3% of the total effect. Subgroup analyses revealed that the mediation effect of impaired sleep quality was more pronounced in early adolescents and varied by sex, with a stronger total and direct effect in boys.
Conclusions: These findings highlight the need for comprehensive interventions targeting both IGD and impaired sleep quality, tailored to specific sexes and developmental stages, to effectively reduce conduct problems.

Background: Various media are used to enhance public understanding about diseases. While mobile health apps are widely used, there is little proof for using such apps to raise awareness of skin diseases.
Objective: We intend to develop an app, called DEDIKASI-app, to raise awareness of skin diseases, including leprosy.

The global epidemic of overweight and obesity is closely linked to the development of chronic kidney disease (CKD), with extremely obese individuals facing a particularly high risk. This study aimed to assess the relationship between lipid profile levels, SIRT1 expression, and RNA-34a-5P in the regulation of blood lipid levels among severely obese individuals with renal diseases. Conducted over six months in three specialized hospitals, the study included 100 participants divided into two groups: 50 obese individuals with renal diseases and 50 obese controls without renal problems.

Orthorexia nervosa is defined as an exaggerated and obsessive fixation on healthy eating. In recent years, there has been growing debate over whether orthorexia nervosa should be considered a new psychiatric disorder. This paper discusses the conceptual issues that emerge from the attempt to identify the diagnostic criteria for orthorexia nervosa as opposed to non-pathological cases of healthy eating or 'healthy orthorexia'.

The COVID-19 pandemic presented a unique opportunity to investigate the longitudinal associations between parents' pre-pandemic mental health issues and their emotion-related parenting practices during the pandemic, as well as the impact on children's socio-emotional functioning. The present study aimed to: 1) investigate associations between pre-existing parent mental health issues (2019) with children's long-term socio-emotional functioning (2021), via changes in emotion-related parenting practices during the COVID-19 pandemic (2020); and 2) test whether COVID-19 pandemic-related environmental stressors during 2020 and 2021 exacerbated associations between emotion-related parenting practices and children's socio-emotional functioning. Data were drawn from the Child and Parent Emotion Study (CAPES).

Microplastics, tiny fragments resulting from the degradation of plastic waste, are abundant in water, air, and soil and are currently recognized as a global environmental problem. There is also growing evidence that nanosized microplastics (nanoplastics) can be hazardous to living species. Unlike most experimental methods, computer modeling is particularly well suited to studying the effects of such nanoplastics.
