The Association Between Academic Achievement and Subsequent Youth Offending: A Systematic Review and Meta-Analysis

By M. Lankester, C. Coles, A. Trotter, S. Scott, J. Downs, H. Dickson, A. Wickersham

The association between academic achievement and youth offending has yet to be clearly quantified. This meta-analysis aims to provide a robust estimate of the longitudinal association between academic achievement and subsequent youth offending. We searched PsycINFO, ERIC, British Education Index, and Web of Science from inception to 2 April 2024 using a comprehensive search strategy. We identified eligible studies reporting on the association between academic achievement and subsequent youth offending, as measured using self-report or administrative records up to the age of 25 years. Correlation coefficients and odds ratios were pooled in a meta-analysis. Effect modifiers were investigated in a sub-group analysis, and other findings were narratively synthesised. PROSPERO record: CRD42023402103. Seventeen studies were included, of which eight were pooled in a meta-analysis. The findings showed a small but statistically significant association between lower academic achievement and youth offending (pooled Fisher z= −0.21, 95% CI [−0.29,−0.12], I 2=98.4%). Subgroup analysis and narrative synthesis yielded mixed findings on the possible role of measurement timing and offence types. Lower academic achievement was associated with subsequent youth offending, underlining the need for a child-first approach to early prevention and intervention strategies in educational and forensic settings.

Revisiting the sexual recidivism drop in Canada and the United States: A meta-analysis of 468 empirical studies involving 388,994 individuals

By Patrick Lussier and Evan McCuish

Objectives

There is empirical evidence that sexual recidivism rates have been dropping for several decades, but it remains unclear whether this drop is an artifact of changing research methodologies over the years. The current study, therefore, examines whether the sexual recidivism drop is robust while accounting for various methodological factors.

Method

The study is based on a systematic review and a quantitative meta-analysis of 468 empirical studies published between 1940 and 2019 that reported sexual recidivism rates. A total of 626 estimations (n = 388,994) of sexual recidivism were retrieved for the study period and of those, 238 were independent observations (n = 196,651). A series of sensitivity analyses were conducted using a meta-regression approach.

Results

A series of meta-regression analyses show that, even after accounting for various methodological factors (e.g., study settings, follow-up length, recidivism criteria), there has been a sexual recidivism rate drop of about 45–60% since the 1970s.

Conclusions

The study findings confirm the presence of a sexual recidivism drop while recognizing that sexual recidivism rates are sensitive to methodological details.

Prevalence and Patterns of Substance Use in West Africa: A Systematic Review and Meta-Analysis

ntroduction

Substance use is a growing public health concern in West Africa, contributing to significant morbidity, mortality, and socioeconomic challenges. Despite the increasing prevalence, comprehensive data on the patterns and factors influencing substance use in the region remain limited. This systematic review and meta-analysis aim to synthesize existing research on the prevalence and patterns of substance use in West Africa, providing critical insights for developing targeted interventions and policies.

Methodology

This study followed the Preferred Reporting Items for Systematic Reviews and Meta-Analyses [PRISMA] guidelines. A systematic search was performed across four major databases [PubMed, Web of Science, CINAHL, and Scopus] from January 2000 to June 2024. A total of 22 studies involving 43,145 participants met the inclusion criteria. Multiple reviewers performed data extraction and quality assessment independently, and a random-effects meta-analysis was used to estimate the pooled prevalence of various substances. Sensitivity analysis was conducted using a leave-one-out approach to evaluate the influence of individual studies on the overall prevalence.

Results

The meta-analysis revealed the pooled prevalence rates of alcohol [44%], cannabis [6%], tramadol [30%], codeine [11%], and kolanut [39%]. The analysis identified high heterogeneity across studies [I2 = 98– 99%], reflecting diverse substance use patterns and influencing factors, including peer influence, availability of substances, socioeconomic conditions, and demographic characteristics. Sensitivity analysis indicated that no single study significantly impacted the overall prevalence estimates, confirming the robustness of the findings.

Conclusion

Substance use in West Africa is widespread and influenced by complex factors. The high prevalence of alcohol and tramadol use highlights the urgent need for targeted public health interventions, including stricter regulatory frameworks, community-based prevention programs, and comprehensive public education campaigns. This study provides a critical foundation for developing effective strategies to mitigate the escalating substance use crisis in the region.

Domestic Violence During the COVID-19 Pandemic: Evidence from a Systematic Review and Meta-Analysis

By Alex R. Piquero and Wesley G. Jennings, et al

In March and April of 2020, government leaders began to impose stay-at-home orders to help contain the spread of the coronavirus. This report, by a team of researchers led by sociologist Alex R. Piquero of the University of Miami, was based on a systematic review of multiple studies that compared changes in the number of domestic violence incidents before and after jurisdictions put lockdown restrictions in place.

Findings:

  • Based on a review of 12 U.S. studies, most of which included data from multiple cities, shows that domestic violence incidents increased 8.1% after jurisdictions imposed pandemic-related lockdown orders.

  • Unlike some early reports on domestic violence trends that relied exclusively on police calls for service, the studies covered by this review also drew on data from crime reports, emergency hotline registries, hospital and other health records, and additional administrative documents.

  • While the precise dynamics driving the increase are unclear, lockdowns and pandemic-related economic impacts likely exacerbated factors typically associated with domestic violence, such as increased male unemployment, stress associated with childcare and homeschooling, and increased financial insecurity. Poor coping strategies, including the increased use of alcohol and other substances, may have elevated the risk of abuse.

  • The authors also conclude that COVID-19 left parents and children confined to their homes, cut off from friends, neighbors, colleagues, and others who might have reported signs of abuse and violence and intervened to help potential victims escape violent situations.
