Background and Aims: Regulations response to COVID‐19 has increased internet addiction (IA), depression, and pornography addiction (PA) among adolescents worldwide. The objective of this nationwide study was to assess the current prevalence rate of IA, depression, and PA after the post‐COVID‐19 period among school‐going adolescents in Bangladesh.Methods: A total of 8832 male and female adolescents participated in this research. The cross‐sectional study was conducted online using a simple random sampling method. Including the sociodemographic variables, Young's IA Test (IAT‐20) Scale, Patient Health Questionnaire (PHQ‐9), and Pornography Craving Questionnaire (PCQ‐12) were used to measure IA, depression, and PA. By SPSS version 25.0, the prevalence and correlation between IA, depression, and PA were analyzed using the Chi‐square test, binary logistic regression, and a bivariate co‐relation matrix.Results: Sixty‐three percent, 76.6%, and 62.9% of the students were suffering from IA, depression, and PA respectively. Depressive and anxious symptoms were significantly associated with IA. Female students were more depressed than males. Males were more addicted to pornography than females. Students who utilized social media but didn't exercise had greater depression and PA. IA, depression, and PA were correlated.Conclusion: The research emphasizes the need for comprehensive mental health treatments, digital literacy programs, and family and teacher participation to reduce IA, depression, and PA among adolescents post‐COVID‐19. Promotion of physical exercise and supporting policies to build safer online settings for adolescents are also encouraged.

Elevated CO2 emissions are a primary cause of the sustainability challenges, including rising sea levels and extreme weather patterns, faced by Bangladesh and the world. This study examines the intricate relationship between CO2 emissions and various economic and industrial factors in Bangladesh, using the autoregressive distributed lag (ARDL) bound test. By analyzing data from 1971 to 2020, the research identifies both short-run and long-run dynamics influencing CO2 emissions. The findings reveal that industrial production and non-renewable energy consumption have a significant positive impact on CO2 emissions, while agricultural activities and fertilizer consumption exhibit a negative effect. The study underscores the need for Bangladesh to transition towards renewable energy sources and improve agricultural practices to mitigate CO2 emissions. Advanced econometric techniques, including the ARDL Bound Test, CUSUM, and CUSUMSQ, are employed to ensure the robustness of the results. The ARDL framework yields key metrics: RMSE = 0.034, MSE = 0.001, AIC = -160.002, BIC = -139.651, R-squared = 0.801, and adjusted R-squared = 0.753, to explore the CO2 emissions nexus in Bangladesh. The study concludes that, while industrial and energy factors significantly contribute to CO2 emissions, enhancing renewable energy use and adopting climate-smart agricultural practices are essential for sustainable environmental management. Policy recommendations include promoting renewable energy adoption, implementing carbon capture technologies, and revising carbon tax policies to achieve long-term sustainability and environmental conservation.

Background: Healthy oral hygiene is crucial for overall health and well-being. Parents’ dental care knowledge and practices affect their children’s oral health. Objective: This study examined mothers’ knowledge and practices regarding their children’s oral hygiene through a cross-sectional survey. Methods: This cross-sectional survey was conducted from January 1 to December 31, 2022, in Dhaka, Bangladesh. Mothers’ knowledge and practices regarding their children’s oral hygiene were assessed through a semistructured questionnaire. Statistical analyses, including the χ² test and Pearson correlation test, were performed. The Mann-Whitney U and Kruskal-Wallis 1-way ANOVA tests were also used to show the average variations in knowledge and practices among different sociodemographic groups. Results: Of 400 participants, the mean age of mothers was 30.94 (SD 5.15) years, and 388 (97%) were of the Muslim faith, 347 (86.8%) were housewives, and 272 (68%) came from nuclear families. A total of 165 (41.3%) participants showed good knowledge of their children’s oral hygiene, followed by 86 (21.5%) showing moderately average knowledge, 75 (18.8%) showing average knowledge, and 74 (18.5%) showing poor knowledge. A total of 182 (45.5%) mothers had children with good oral hygiene practices, followed by mothers with children who had average (n=78, 19.5%), moderately average (n=75, 18.8%), and poor (n=65, 16.3%) oral hygiene practices. The mother’s knowledge level was significantly associated with age (P=.01), education (P<.001), family size (P=.03), and monthly income (P<.001). On the other hand, educational status (P=.002) and income (P=.04) were significantly associated with the mother’s practices regarding their children’s oral hygiene. Nonparametric analysis revealed that mothers who were older (mean knowledge score: 12.13, 95% CI 10.73-13.54 vs 11.21, 95% CI 10.85-11.58; P=.01), with a bachelor’s degree or higher (mean knowledge score: 12.93, 95% CI 12.55‐13.31 vs 9.66, 95% CI 8.95‐10.37; P<.001), who were working mothers (mean knowledge score: 12.30, 95% CI 11.72‐12.89 vs 11.45, 95% CI 11.17‐11.73; P=.03), and who had a higher family income (mean knowledge score: 12.49, 95% CI 12.0‐12.98 vs 10.92, 95% CI 10.48‐11.36; P<.001) demonstrated significantly higher levels of oral health knowledge. Conversely, good oral hygiene practices were significantly associated with higher maternal education (mean practice score: 6.88, 95% CI 6.54‐7.22 vs 6.01, 95% CI 5.63‐6.40; P<.001) and family income (mean practice score: 6.77, 95% CI 6.40‐7.14 vs 5.96, 95% CI 5.68‐6.24; P=.002). The mother’s knowledge was also significantly and positively correlated (Pearson correlation coefficient r=0.301; P<.001) with their children’s oral hygiene practices, shown by both the Pearson chi-square (χ²=25.2; P<.001) test and correlation coefficient. Conclusions: The mothers’ knowledge and their children’s oral hygiene practices were inadequate. The mother’s age, education level, family size, and monthly income significantly influenced their knowledge level. Children’s oral hygiene habits were significantly associated with family income and the mother’s educational status. This underscores the need for educational programs, accessible dental care services, oral health education in the curriculum, media and technology involvement in oral health educational campaigns, and proper research and monitoring.

The use of lethal force by law enforcement against protesters is a critical issue in Bangladesh, where police actions during the July 24 Revolution resulted in more than a thousand recorded deaths. This study analyses the circumstances, demographics, and geographic distribution of these fatalities through a quantitative content analysis of national newspaper reports of 253 deaths, verified through a multi-step validation process to reduce bias. The findings reveal that young adults aged 18 to 29 accounted for 58.1% of victims, underscoring the historical role of youth in political mobilization. Lethal bullets were responsible for 78.66% of deaths, with most fatalities occurring on the spot (77.47%) and predominantly at demonstration sites (75.89%). The chest (46.64%) and head (29.25%) were the most frequently targeted areas, suggesting intentional use of lethal force inconsistent with international norms on proportionality and necessity. These patterns illustrate how the securitization of dissent discursively frames protesters as threats, legitimizing violent repression consistent with broader theories of state violence. In doing so, the findings extend global debates on protest policing by showing how securitization discursively legitimized the lethal targeting of youth protesters in a South Asian context. By situating Bangladesh within South Asian and global debates on protest policing, the study contributes to understanding how state violence undermines democratic participation and public health. The analysis aligns with the World Health Organization's objectives on reducing violence and promoting human rights. While limited by reliance on media reports and cross-sectional data, the findings highlight the need for future research on long-term impacts and for context-specific reforms in accountability, training, and oversight.
