Adverse Childhood Experiences and Associations with Mental Health, Substance Use, and Violence Perpetration among Young Adults in sub-Saharan Africa

Violence against children and later substance use in low- and middle-income countries

BACKGROUND

Globally, one in two children experience violence; experiences which may lead to later risky behaviors such as substance use. In low- and middle-income countries (LMICs), however, the association between childhood violence and substance use remains underexplored.

OBJECTIVE

This study assessed the association between childhood violence and substance use among LMIC youth.

PARTICIPANTS

Data from the Violence Against Children and Youth Surveys (VACS) in eight LMICs (2017-2019) were analyzed, comprising 33,408 children and young adults (ages 13-24).

METHODS

Exposure variables included the experience of childhood violence (physical, sexual, emotional) and polyvictimization (experience of two or more types). Outcomes were current smoking and past-month alcohol and drug use. Multivariable logistic regressions with country-fixed effects were estimated. Stratified analyses were performed based on participant's sex and age, and effect modification analyses examined whether associations differ by the presence of peer support.

RESULTS

Childhood physical violence was the most prevalent type of violence (40.7 %), and about 10 % of the participants experienced polyvictimization. All types of violence increased the odds of smoking, binge drinking, and drug use, and polyvictimization elevated the risk substantially. Stronger associations were observed in young women with a history of childhood sexual violence (current smoking aOR: 1.5, 95 % CI: 1.2-1.9; binge-drinking aOR: 2.1, 95 % CI: 1.7-2.5; and drug-use aOR: 2.3, 95 % CI: 1.5-3.5) compared to young men. Additionally, the associations between childhood sexual violence and substance use were more pronounced among adolescents (current smoking aOR: 1.7, 95 % CI: 1.2-2.2; binge-drinking aOR: 2.3, 95 % CI: 1.8-2.9; and drug-use aOR: 2.4, 95 % CI: 1.5-3.9), relative to young adults. Lack of peer support significantly increased the likelihood of drug use.

CONCLUSION

Childhood violence prevention programs can reduce substance use in LMICs, and they should take into account the survivor's sex and age. Our findings suggest that peer support can mitigate risky behaviors among the survivors of childhood violence.

A qualitative study of coping strategies and resilience in the aftermath of childhood adversity in first-episode psychosis

AIM

Exposure to adversity during childhood is associated with elevated risk for commonly occurring forms of psychopathology, especially psychotic disorders. Despite the noteworthy consequences associated with adverse childhood experiences, an inconsistent and unpredictable number of at-risk populations present with remarkably good physical and mental health outcomes that can be attributed to resilience. This study aimed to qualitatively explore the experience of childhood adverse events and coping strategies employed by individuals that promote resilience and better mental health outcomes.

METHODS

Fourteen individuals with a history of childhood adversity were recruited to participate using a case-study approach. A semi-structured interview guide was developed based on empirical evidence and theoretical background, and the interviews were analysed using a reflexive thematic approach.

RESULTS

Our findings showed that the type of adversity impacted the experience of trauma, for example, the death of a caregiver versus emotional abuse or witnessing violence at home. Five coping strategies were identified (social support, religious coping, problem or emotion-focused coping, and meaning-making), with healthy controls found to identify and use these resources more than the psychosis group to promote individual well-being and better mental health outcomes.

CONCLUSIONS

Our findings provide insights into experiences in the aftermath of childhood adversity, emphasising the need to assess the history of trauma systematically. They further underscore the importance of mental health prevention programmes bolstering individual-level coping strategies and the resources available within our environments to help them manage adversity, improve overall outcomes, and promote resilience.
