Substance use and adolescent injuries: a multi-country analysis of the association and mediating effect of interpersonal violence among 122,945 in-school paediatric populations in 29 countries.

Background: Adolescent use of substances and injury experiences such as head injury have become increasingly prevalent. However, information regarding their association and the potential pathways linking them remains limited. This study examined the association between substance use and injuries, emphasizing the mediating role of interpersonal violence among adolescents. Methods: We employed a multi-country analysis of Global School-based Health Surveys of 122,945 in-school adolescents aged 11-18 from 29 countries. This study was a cross-sectional school-based, nationally representative study developed by the World Health Organization and the United States Centers for Disease Control and Prevention, other United Nations allies, and country-specific institutions. Random-effects meta-analysis was performed to estimate the overall prevalence of injury and substance use and the I-square (I2) statistic was used to investigate the between-country heterogeneity. Logistic regression models were fitted to examine the association between substance use and injuries. A path analysis was used to examine the potential mediation effect of interpersonal violence and employed decomposition of effects into total, direct, and indirect. Results: Prevalence of substance use and injuries were 33.6% (95%CI = 28.5, 38.6%) and 41.7% (95%CI = 37.3, 46.1%), respectively. Substance use (37.8% vs. 29.4%, p = 0.001) and injuries (47.3% vs. 36.4%, p = 0.001) were significantly higher among male adolescents than females, respectively. After adjustment, substance users had 40% higher odds of injuries. The path analysis showed a mediation effect of perpetration of and victimization by interpersonal violence on the association of substance use with injuries, with total positive effects of perpetration [ß = 0.18; 95%CI = 0.16, 0.19; p = 0.001] and victimization on injuries [ß = 0.22; 95%CI = 0.21, 0.24; p = 0.001]. In a further subgroup analysis, tobacco users were 3.98 times more likely to sustain a gunshot wound whiles marijuana users had 2.81 times higher odds of sustaining gunshot wounds. Cigarette smokers had 45% lower odds of sustaining cut/stab wounds. Alcohol users were 53% more likely to sustain concussion/head injury and two and half times more likely to sustain gunshot wound. Conclusion: A significant association exists between substance use and severe injuries among adolescents, mediated by interpersonal violence exposure. Our findings may have utility in informing substance use and interpersonal violence control policies and interventions to address adolescent injuries.

Association of food insecurity and sleep difficulty among 189,619 school-going adolescents: a study from the global in-school students survey.

Introduction: Adolescents' sleep disturbances are associated with chronic and dramatic physical, emotional, and mental development and school performance consequences. Although food insecurity could significantly contribute to these effects, few studies have explored the effect of food insecurity on sleep disturbances among adolescents. The study aimed to examine the relationship between adolescents' food insecurity and sleep disturbance. Methods: Data on 189,619 adolescents were drawn from the cross-sectional global adolescent health surveys conducted between 2015 and 2018 in 35 countries and territories. Univariate and multivariable multinomial regression models were fitted to examine the hypothesized associations. Results: Overall pooled prevalence of moderate [45.2% (95%CI = 43-47)] and severe [5.8% (95%CI = 5-6)] food insecurity levels were reported. About [52.6% (95%CI = 51-54)] moderate and [8.6% (95%CI = 8-9)] severe worry-induced sleep disturbances were found. Considering the fully adjusted multinomial logistic model, moderate food insecurity was significantly associated with moderate (AOR = 1.70 CI = 1.59-1.81; p < 0.0001) and severe (AOR = 1.63 CI = 1.42-1.87; p < 0.0001) sleep disturbances. Also, adolescents reporting severe levels of food insecurity had moderate (AOR = 1.88 CI = 1.68-2.11; p < 0.0001) and severe (AOR = 4.07 CI = 4.74-6.11; p < 0.0001) sleep disturbances. Females and those aged between 15 and 17 years and 18 or more were at higher risk of moderate and severe sleep disturbances in the context of food insecurity. Conclusion: Reducing food insecurity could be an effective policy strategy for enhancing adolescent sleep quality.

Removing barriers to healthcare through an intercultural healthcare system: Focus group evidence.

OBJECTIVE: Barriers to healthcare in Ghana are multifaceted. Many people, including patients and providers, face them at different levels. To address these barriers, there is a need to explore the role of an intercultural healthcare system. This paper explores and provides the first evidence on ways through which an intercultural healthcare system can reduce the sociocultural and economic barriers to healthcare in Ghana. METHODS: Focus group discussions with 35 participants comprising 17 healthcare users, 11 formal healthcare providers and 7 alternative healthcare providers were conducted to gather data. Thematic analyses were performed on the transcribed data and presented based on a posteriori inductive reduction approach. RESULTS: Findings reveal that an intercultural healthcare system in Ghana can help reduce barriers to healthcare, especially cultural, social and economic barriers, by fostering an enhanced relationship between culture and healthcare, promoting affordable healthcare and promoting effective communication between healthcare providers and users. Weak institutional support, lack of strong political will and commitment, lack of training to meet standards of practice, poor registration and regulatory measures, and lack of universal acceptance inhibit implementation of an intercultural healthcare system in Ghana. CONCLUSION: The support for intercultural healthcare system and the agreement on its perceived ability to reduce social, cultural and economic healthcare barriers for service users offer an opportunity for policymakers to demonstrate a stronger political will and improved commitment for effective education and training, enforcement of regulatory measures, inclusion of intercultural healthcare in medical school curricula across the country, and community engagement.
