A two-level strategy for implementing evidence-based mental health treatment was assessed in a 2 × 2 randomized trial with 615 delinquent youth in 14 rural Appalachian counties. The implementation strategy included (1) the introduction of a Multisystemic Therapy (MST) program for delinquent youth in each county, and (2) the ARC (for Availability, Responsiveness and Continuity) organizational intervention for implementing effective community-based mental health services in randomly assigned counties. Within each county, youth were randomly assigned to the MST program or to usual services programs, yielding 4 treatment conditions (MST plus ARC, MST only, ARC only, control). Results of multilevel mixed-effects regression analyses found both main and interaction effects of MST and ARC on youth outcomes. Total problem behaviors as measured by the Child Behavior Checklist (CBCL) decreased significantly to non-clinical levels in the MST plus ARC condition by the six-month post-test, but were at clinical levels for youth in the MST only, ARC only, and control conditions. In addition, youth in the MST plus ARC condition entered out-of-home placements at less than half the rate (16%) of youth in the control condition (34%).
Summary Background Sub-Saharan Africa has the highest incidence, prevalence, and fatality from stroke globally. Yet, only little information about context-specific risk factors for prioritising interventions to reduce the stroke burden in sub-Saharan Africa is available. We aimed to identify and characterise the effect of the top modifiable risk factors for stroke in sub-Saharan Africa. Methods The Stroke Investigative Research and Educational Network (SIREN) study is a multicentre, case-control study done at 15 sites in Nigeria and Ghana. Cases were adults (aged ≥18 years) with stroke confirmed by CT or MRI. Controls were age-matched and gender-matched stroke-free adults (aged ≥18 years) recruited from the communities in catchment areas of cases. Comprehensive assessment for vascular, lifestyle, and psychosocial factors was done using standard instruments. We used conditional logistic regression to estimate odds ratios (ORs) and population-attributable risks (PARs) with 95% CIs. Findings Between Aug 28, 2014, and June 15, 2017, we enrolled 2118 case-control pairs (1192 [56%] men) with mean ages of 59.0 years (SD 13.8) for cases and 57.8 years (13.7) for controls. 1430 (68%) had ischaemic stoke, 682 (32%) had haemorrhagic stroke, and six (<1%) had discrete ischaemic and haemorrhagic lesions. 98.2% (95% CI 97.2–99.0) of adjusted PAR of stroke was associated with 11 potentially modifiable risk factors with ORs and PARs in descending order of PAR of 19.36 (95% CI 12.11–30.93) and 90.8% (95% CI 87.9–93.7) for hypertension, 1.85 (1.44–2.38) and 35.8% (25.3–46.2) for dyslipidaemia, 1.59 (1.19–2.13) and 31.1% (13.3–48.9) for regular meat consumption, 1.48 (1.13–1.94) and 26.5% (12.9–40.2) for elevated waist-to-hip ratio, 2.58 (1.98–3.37) and 22.1% (17.8–26.4) for diabetes, 2.43 (1.81–3.26) and 18.2% (14.1–22.3) for low green leafy vegetable consumption, 1.89 (1.40–2.54) and 11.6% (6.6–16.7) for stress, 2.14 (1.34–3.43) and 5.3% (3.3–7.3) for added salt at the table, 1.65 (1.09–2.49) and 4.3% (0.6–7.9) for cardiac disease, 2.13 (1.12–4.05) and 2.4% (0.7–4.1) for physical inactivity, and 4.42 (1.75–11.16) and 2.3% (1.5–3.1) for current cigarette smoking. Ten of these factors were associated with ischaemic stroke and six with haemorrhagic stroke occurrence. Interpretation Implementation of interventions targeting these leading risk factors at the population level should substantially curtail the burden of stroke among Africans.

ObjectivesSchool-based sex education is a cornerstone of HIV prevention for adolescents who continue to bear a disproportionally high HIV burden globally. We systematically reviewed and meta-analyzed the existing evidence for school-based sex education interventions in low- and middle-income countries to determine the efficacy of these interventions in changing HIV-related knowledge and risk behaviors.MethodsWe searched five electronic databases, PubMed, Embase, PsycInfo, CINAHL, and Sociological Abstracts, for eligible articles. We also conducted hand-searching of key journals and secondary reference searching of included articles to identify potential studies. Intervention effects were synthesized through random effects meta-analysis for five outcomes: HIV knowledge, self-efficacy, sexual debut, condom use, and number of sexual partners.ResultsOf 6191 unique citations initially identified, 64 studies in 63 articles were included in the review. Nine interventions either focused exclusively on abstinence (abstinence-only) or emphasized abstinence (abstinence-plus), whereas the remaining 55 interventions provided comprehensive sex education. Thirty-three studies were able to be meta-analyzed across five HIV-related outcomes. Results from meta-analysis demonstrate that school-based sex education is an effective strategy for reducing HIV-related risk. Students who received school-based sex education interventions had significantly greater HIV knowledge (Hedges g = 0.63, 95% Confidence Interval (CI): 0.49–0.78, p<0.001), self-efficacy related to refusing sex or condom use (Hedges g = 0.25, 95% CI: 0.14–0.36, p<0.001), condom use (OR = 1.34, 95% CI: 1.18–1.52, p<0.001), fewer sexual partners (OR = 0.75, 95% CI:0.67–0.84, p<0.001) and less initiation of first sex during follow-up (OR = 0.66, 95% CI: 0.54–0.83, p<0.001).ConclusionsThe paucity of abstinence-only or abstinence-plus interventions identified during the review made comparisons between the predominant comprehensive and less common abstinence-focused programs difficult. Comprehensive school-based sex education interventions adapted from effective programs and those involving a range of school-based and community-based components had the largest impact on changing HIV-related behaviors.
The primary purpose of this study is to examine the effects of South Carolina's comprehensive registration policy on recidivism of juveniles who sexually offend. Registered and nonregistered male youth are matched on year of index offense, age at index offense, race, prior person offenses, prior nonperson offenses, and type of index sexual offense, for a total of 111 matched pairs. Recidivism is assessed across a mean 4.3-year follow-up (SD = 2.5). The sexual offense reconviction rate is too low (2 events) to support between-group analyses. Cox regression results indicate no significant between-group differences with respect to new nonsexual person offense convictions but significant between-group differences with respect to new nonperson offense convictions. Specifically, registered youth are more likely than nonregistered youth to have new nonperson offense convictions across follow-up. Public policy implications of these findings are discussed.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
