Effects of a violence prevention intervention in schools and surrounding communities: Secondary analysis of a cluster randomised-controlled trial in Uganda.

The Good School Toolkit is effective in reducing staff violence against children in Ugandan primary schools. A secondary analysis of cluster-randomised trial data was conducted to investigate intervention effects on school operational culture, and on normative beliefs and violence against children from caregivers outside of school. Students and staff completed cross-sectional surveys at baseline in 2012 and follow-up in 2014. Students' caregivers completed follow-up surveys only. Data from 3820 students, 597 staff, and 799 caregivers were included in cross-sectional analyses at follow-up. Statistically significant intervention effects were observed for aspects of school operational culture, including students' greater perceived emotional support from teachers and peers, students' greater identification with their school, students' and staffs' lower acceptance of physical discipline practices in school, and students' and staffs' greater perceived involvement in school operations. Outside the school, the intervention was associated with significantly lower normative beliefs accepting the use of physical discipline practices in schools (adjusted mean difference, AMD: -0.77; 95%CI: -0.89 to -0.66; p < 0.001) and at home (AMD: -0.67; 95%CI: -0.80 to -0.54; p < 0.001), based on aggregated caregiver reports. No differences between groups were observed in past-week violence against children at home. This intervention shows promise as a platform for addressing violence against children within the school environment and surrounding community

School staff perpetration of physical violence against students in Uganda: a multilevel analysis of risk factors.

OBJECTIVE: To conduct a multilevel analysis of risk factors for physical violence perpetration by school staff against Ugandan students. DESIGN: Multilevel logistic regression analysis of cross-sectional survey data from 499 staff and 828 caregivers of students at 38 primary schools, collected in 2012 and 2014 during the Good Schools Study. SETTING: Luwero District, Uganda. MAIN OUTCOME MEASURE: Past-week use of physical violence by school staff against students was measured using the International Society for the Prevention of Child Abuse and Neglect 'Child Abuse Screening Tool- Child International' and the WHO Multi-Country Study on Women's Health and Domestic Violence against Women. RESULTS: Of 499 staff, 215 (43%) reported perpetration of physical violence against students in the past week. Individual risk factors associated with physical violence perpetration included being a teacher versus another type of staff member (p<0.001), approving of physical discipline practices (p<0.001), having children (p<0.01), being age 30-39 years (p<0.05), using physical violence against non-students (p<0.05) and being a victim of intimate partner violence (IPV) (p<0.05). We observed weak evidence (p=0.06) that male staff members who had been a victim of IPV showed higher odds of violence perpetration compared with male staff who had not been a victim of IPV. No evidence was observed for school- or community-level risk factors. CONCLUSIONS: Physical violence perpetration from school staff is widespread, and interventions are needed to address this issue. Staff who have been victims of violence and who use violence against people other than students may benefit from additional interventions. Researchers should further investigate how school and community contexts influence staff's physical violence usage, given a lack of associations observed in this study

The Effects of Acute Beetroot Juice Ingestion on Exercise and Cognitive Performance in Female Athletes

Nitrate-rich beetroot juice can enhance intense exercise performance which is attributed to enhanced skeletal muscle contractility. However, limited data exist in females and it is unknown whether dietary nitrate has an ergogenic effect in this population. PURPOSE: To investigate the potential effects of acute nitrate ingestion on a battery of exercise performance and cognitive tests before and after fatiguing intermittent running exercise. METHODS: Fifteen female team-sport athletes were assigned in a randomized, double-blind, crossover design to consume nitrate-rich beetroot juice (BR; 12 mmol of nitrate) and nitrate-depleted beetroot juice (PL; 0.10 mmol of nitrate) 2.5 h prior to performing the exercise protocol, with a washout period of 7 days between trials. Running 10 m and 20 m sprint split times, sprint reaction time, upper- and lower-body power, handgrip strength, and cognitive flexibility were measured before and after the Yo-Yo intermittent recovery level 1 (Yo-Yo IR1) test, during which performance and rate of perceived exertion were recorded. RESULTS: There were no significant differences in any performance outcome or cognitive flexibility (P \u3e 0.05). CONCLUSION: These findings indicate that acute nitrate ingestion does not influence performance in sprints, intermittent running, power, strength, or cognitive function in young adult female team-sport athletes

Effect of the good school toolkit on school staff mental health, sense of job satisfaction and perceptions of school climate: Secondary analysis of a cluster randomised trial.

The Good School Toolkit, a complex behavioural intervention delivered in Ugandan primary schools, has been shown to reduce school staff-perpetrated physical violence against students. We aimed to assess the effect of this intervention on staff members' mental health, sense of job satisfaction and perception of school climate. We analysed data from a cluster-randomised trial administered in 42 primary schools in Luwero district, Uganda. The trial was comprised of cross-sectional baseline (June/July 2012) and endline (June/July 2014) surveys among staff and students. Twenty-one schools were randomly selected to receive the Toolkit, whilst 21 schools constituted a wait-listed control group. We generated composite measures to assess staff members' perceptions of the school climate and job satisfaction. The trial is registered at clinicaltrials.gov (NCT01678846). No schools dropped out of the study and all 591 staff members who completed the endline survey were included in the analysis. Staff in schools receiving the Toolkit had more positive perspectives of their school climate compared to staff in control schools (difference in mean scores 2.19, 95% Confidence Interval 0.92, 3.39). We did not find any significant differences for job satisfaction and mental health. In conclusion, interventions like the Good School Toolkit that reduce physical violence by school staff against students can improve staff perceptions of the school climate, and could help to build more positive working and learning environments in Ugandan schools

The association between violence victimization and subsequent unplanned pregnancy among adolescent girls in Uganda: Do primary schools make a difference?

Violence victimization is a risk factor for adolescent pregnancy in high-income, low violence prevalence countries, but longitudinal data are lacking from settings where violence and adolescent pregnancy are common, including sub-Saharan Africa. We also know little about contextual factors which modify this association. We analyzed data from the Contexts of Violence in Adolescence Cohort (CoVAC) study in Luwero District, Uganda. Primary students in 42 schools completed surveys in 2014 (Wave 1) and 2018 (Wave 2). Our outcome was unplanned pregnancy. Our exposure was violence victimization, including any violence, type of violence (physical, emotional, sexual), perpetrator group (teacher, peer, family member), and polyvictimization. We fit mixed-effects logistic regression models and examined school factors (e.g., connectedness, absenteeism) as effect modifiers, using data from students (n = 3,431) and staff (n = 591) at the 42 schools. 1,449 girls were included in analyses (78% follow-up). At Wave 1, 88% (n = 1,281/1,449) reported any violence (mean age = 12.73, SD = 1.44 years). At Wave 2, 13.9% (n = 201/1,449) reported an unplanned pregnancy. In adjusted models, compared to no violence, significant associations (p<0.05) were observed for any violence (OR = 1.99, 95%CI = 1.03-3.85), physical violence (OR = 1.96, 95%CI = 1.02-3.79), teacher violence (OR = 1.96, 95%CI = 1.01-3.79), peer violence (OR = 2.00, 95%CI = 1.00-4.03), family violence (OR = 2.23, 95%CI = 1.07-4.65), violence from one perpetrator group (OR = 2.04, 95%CI = 1.01-4.15), and violence from three perpetrator groups (OR = 2.21, 95%CI = 0.99-4.95). Sexual and emotional violence were associated in crude but not adjusted analyses. School and peer connectedness modified the association (p<0.05); girls who experienced violence had higher odds of unplanned pregnancy in schools with lower versus higher connectedness. Violence victimization in early adolescence is strongly associated with subsequent unplanned pregnancy among adolescent girls in Uganda but attending schools with more school or peer connectedness attenuated this link. Interventions should seek to reduce violence against girls to prevent unplanned pregnancy. Interventions promoting positive connections to school may be especially important for violence victims

Project YES! Youth Engaging for Success: A randomized controlled trial testing a peer mentoring approach among HIV-positive adolescents and young adults in Ndola, Zambia

This research addresses the gaps in knowledge about how to best support adolescents and young adults transitioning to HIV self-management in the context of both child-focused and adult-focused HIV care settings. Johns Hopkins University, in partnership with the Arthur Davison Children’s Hospital, implemented this study through the USAID-funded Project SOAR (led by the Population Council)

Who perpetrates violence against children? A systematic analysis of age-specific and sex-specific data.

OBJECTIVE: The epidemiology of violence against children is likely to differ substantially by sex and age of the victim and the perpetrator. Thus far, investment in effective prevention strategies has been hindered by lack of clarity in the burden of childhood violence across these dimensions. We produced the first age-specific and sex-specific prevalence estimates by perpetrator type for physical, sexual and emotional violence against children globally. DESIGN: We used random effects meta-regression to estimate prevalence. Estimates were adjusted for relevant quality covariates, variation in definitions of violence and weighted by region-specific, age-specific and sex-specific population data to ensure estimates reflect country population structures. DATA SOURCES: Secondary data from 600 population or school-based representative datasets and 43 publications obtained via systematic literature review, representing 13 830 estimates from 171 countries. ELIGIBILITY CRITERIA FOR SELECTING STUDIES: Estimates for recent violence against children aged 0-19 were included. RESULTS: The most common perpetrators of physical and emotional violence for both boys and girls across a range of ages are household members, with prevalence often surpassing 50%, followed by student peers. Children reported experiencing more emotional than physical violence from both household members and students. The most common perpetrators of sexual violence against girls aged 15-19 years are intimate partners; however, few data on other perpetrators of sexual violence against children are systematically collected internationally. Few age-specific and sex-specific data are available on violence perpetration by schoolteachers; however, existing data indicate high prevalence of physical violence from teachers towards students. Data from other authority figures, strangers, siblings and other adults are limited, as are data on neglect of children. CONCLUSIONS: Without further investment in data generation on violence exposure from multiple perpetrators for boys and girls of all ages, progress towards Sustainable Development Goals 4, 5 and 16 may be slow. Despite data gaps, evidence shows violence from household members, peers in school and for girls, from intimate partners, should be prioritised for prevention.

Violence against children in Latin America and the Caribbean: What do available data reveal about prevalence and perpetrators?

OBJECTIVE: To describe the prevalence of recent physical, sexual, and emotional violence against children 0 - 19 years of age in Latin America and the Caribbean (LAC) by age, sex, and perpetrator. METHODS: A systematic review and analysis of published literature and large international datasets was conducted. Eligible sources from first record to December 2015 contained age-, sex-, and perpetrator-specific data from LAC. Random effects meta-regressions were performed, adjusting for relevant quality covariates and differences in violence definitions. RESULTS: Seventy-two surveys (2 publications and 70 datasets) met inclusion criteria, representing 1 449 estimates from 34 countries. Prevalence of physical and emotional violence by caregivers ranged from 30% - 60%, and decreased with increasing age. Prevalence of physical violence by students (17% - 61%) declined with age, while emotional violence remained constant (60% - 92%). Prevalence of physical intimate partner violence (IPV) ranged from 13% - 18% for girls aged 15 - 19 years. Few or no eligible past-year estimates were available for any violence against children less than 9 years and boys 16 - 19 years of age; sexual violence against boys (any age) and girls (under 15 years); IPV except for girls aged 15 - 19 years; and violence by authority figures (e.g., teachers) or via gangs/organized crime. CONCLUSION: Past-year physical and emotional violence by caregivers and students is widespread in LAC across all ages in childhood, as is IPV against girls aged 15 - 19 years. Data collection must be expanded in LAC to monitor progress towards the sustainable development goals, develop effective prevention and response strategies, and shed light on violence relating to organized crime/gangs
