Smartphone use among adolescents has surged globally, reshaping communication and learning patterns, especially in developing countries. However, the implications of such digital habits on students in rural or under-resourced areas remain underexplored. This study aims to examine the patterns of smartphone usage and its effects on learning among high school students in Tarutung, a developing region of North Sumatra, Indonesia. Utilizing a quantitative descriptive approach, data were collected from 358 students using structured questionnaires. The results show that 96.05% of students own personal smartphones regardless of socioeconomic background, with an average daily usage of 4 hours and 45 minutes. While 91.81% believe smartphones support their learning, 25.99% report declining academic performance. Alarmingly, 20.62% of students admitted involvement in cyberbullying activities, highlighting a critical digital risk impacting the school environment and student well-being. The study concludes that although smartphones offer educational benefits, their misuse can lead to negative academic, social, and psychological outcomes. This study recommends digital literacy curricula and structured cooperation between parents and educators to prevent risks while optimizing educational opportunities in smartphone use.

Objective: This study explores the relationship between neighborhood stress and Body Mass Index (BMI) in adolescents, while also examining whether this association differs between Black and White adolescents. Methods: Data from the Adolescent Brain Cognitive Development (ABCD) Study were analyzed using linear regression models to examine the association between neighborhood stress (defined as a composite score based on three items measuring perceived safety and neighborhood fear) and BMI in adolescents, controlling for demographic and socioeconomic variables. We tested models both with and without interaction terms to assess whether race moderated the association. Stratified analyses were conducted to further explore potential differences between Black and White adolescents. Results: A positive association was observed between neighborhood stress and BMI across the overall sample. However, this association was weaker for Black adolescents compared to White adolescents, even after adjusting for potential confounders. Conclusions: The contribution of neighborhood stress to higher BMI in adolescents may vary by race. Our findings suggest that while neighborhood stress is associated with increased BMI, Black adolescents appear to be less affected by these stressors than their White peers. This weaker association could be due to the normalization of stress in environments where it is pervasive (what is common becomes normal) or the presence of other significant risk factors affecting BMI in Black youth, such as poverty, limited food access, food culture, and food deserts. Future research should explore processes of habituation, inoculation, or even sensitization to stress among Black populations, who are often exposed to a wide range of stressors throughout the life course.

The COVID-19 pandemic has had a significant impact on individuals worldwide, affecting not only their educational futures but also their mental health. This paper aims to explore college students' perceived barriers to accessing mental health services during the pandemic. The study finds that there is a significant difference between stigma-related and non-stigma-related barriers, with non-stigma items being rated higher on average. The most commonly reported non-stigma barriers include wanting to solve the problem independently, financial constraints, and the belief that the issue will resolve itself. Stigma-related barriers include feeling embarrassed or ashamed, concern about having a mental health problem on medical records, and fear of being seen as crazy or weak. This research sheds light on the challenges students face in seeking mental health care during the pandemic and highlights the need to address these barriers.

Background: On the first of October 2018, the Egyptian Ministry of Health and Population (MOHP) launched an initiative; named “100 Million Healthy Lives”, for nationwide screening of hepatitis c virus (HCV) and non-communicable diseases (NCDs). Egypt has the highest prevalence of HCV infection in the world where about 10% of the Egyptian population is affected by the disease. NCDs are the leading cause of mortality in Egypt and account for about 84% of all deaths. This study was conducted to a) Estimate the prevalence of participation in the national campaign on viral hepatitis C and non-communicable diseases among administrative workers in Ain shams University (ASU), b) Estimate the self-reported satisfaction of these participants with the campaign. Subjects and Methods: A cross-sectional study was conducted on 400 administrative workers of ASU faculties between March and August 2019 in Cairo, Egypt. A multistage random sample was done. Results: The study showed that 96% of the study group participated in the campaign. “Evaluating health status” was considered the main reason for participation at 92%, followed by "desire to obtain follow-up card", at 36%. Non-participation rate was about 4% and the main cause of non-participation was “fear of needle prick". About 91% of the participants were satisfied with the provided services. Mass media played a major role in awareness about the campaign for 91% of participants. Conclusions: The majority of the study group participated and was satisfied with the campaign. Mass media played a major role in participant awareness of the campaign.
