The V-BRCH Project: Strengthening HIV Research Capacity in Nigeria through Intensive Workshops in Implementation Science and Grant Writing.

As persons with HIV live longer as the result of antiretroviral therapy, morbidity from HIV-associated noncommunicable diseases (NCDs) is increasing. The Vanderbilt-Nigeria Building Research Capacity in HIV and Noncommunicable Diseases program is a training platform created with the goal of training a cohort of successful Nigerian investigators to become leaders in HIV-associated NCD research. We describe survey findings from two week-long workshops in Kano, Nigeria, where trainees received instruction in implementation science and grant writing. Surveys assessed participants' self-perceived knowledge and confidence in topics taught during these workshops. Thirty-seven participants (all assistant professors) attended the implementation science workshop; 30 attended the grant-writing workshop. Response rates for the implementation science workshop were 89.2% for the preworkshop survey and 91.9% for the postworkshop survey. For the grant-writing workshop, these values were 88.2% and 85.3%, respectively. Improvement in participant knowledge and confidence was observed in every domain measured for both workshops. On average, a 101.4% increase in knowledge and a 118.0% increase in confidence was observed across measured domains among participants in the implementation science workshop. For the grant-writing workshop, there was a 68.8% increase in knowledge and a 70.3% increase in confidence observed. Participants rated the workshops and instructors as effective for both workshops. These workshops improved participants' knowledge and competence in implementation science and grant writing, and provide a model for training programs that aim to provide physician scientists with the skills needed to compete for independent funding, conduct locally relevant research, and disseminate research findings.

Training the next generation of Biostatisticians in West Africa: The Vanderbilt Nigeria Biostatistics Training Program (VN-BioStat).

Biomedical HIV research is growing in West Africa, but biostatistical expertise is lagging. The Vanderbilt-Nigeria Biostatistics Training Program (VN-BioStat) seeks to establish a research and training platform for biostatisticians doing HIV-related research in Nigeria. The objectives of the program are: 1) Host two Nigerian data scientists per year (a total of 10 over 5 years) at Vanderbilt University Medical Center to gain hands-on biostatistics training and experience via one-year fellowships. Eligible trainees will be junior investigators with PhDs or nearing completion of their PhDs in statistics or related fields, including mathematics and computer science. 2) Conduct annual workshops in Nigeria to provide biostatistics training. Trainees will undertake biostatistics coursework and hands-on training and participate in mentorship as biostatisticians involved in HIV research. Trainees will be at Vanderbilt for a full year and be part of an active biostatistics department. They will be immersed in a dry-lab HIV biostatistics project in collaboration with a Nigerian HIV research project and lead a methodologically focused research project. They will also participate in a one-month research training/grant writing program in Nashville. The VN-BioStat program will build on the existing momentum of ongoing initiatives to enhance research capacity in Nigeria by developing biostatistics leadership. VN-BioStat trainees will interact with investigators from Nigeria to provide collaborative biostatistical assistance with study design and data analysis, thus gaining real-world experience that will benefit the trainees and the broader research community in Nigeria.

Feasibility evaluation of the Reaching Out to Kids with Emotional Trauma (ROcKET) intervention in an elementary school: a single-arm, single-centre, feasibility study based on the RE-AIM framework.

OBJECTIVE: The study purpose was to describe feasibility of implementation of the Reaching Out to Kids with Emotional Trauma (ROcKET) intervention. We hypothesised that the ROcKET Intervention would be feasible in a poor resource school. DESIGN: We performed a single-arm, single-centr feasibility study of an intervention pilot, based on the RE-AIM framework. SETTING: The intervention was delivered in a single K-4th elementary charter school in the Nashville, TN area, in a low-resource community. PARTICIPANTS: 57 elementary school children attending our partner school and reporting exposure to at least one adverse childhood experience (ACE) and their parents. INTERVENTIONS: The Reaching Out to Kids with Emotional Trauma (ROcKET) intervention is a school-based multilevel intervention (individual child, family and school) that promotes positive health behaviours in children who have been exposed to ACEs. OUTCOMES: Outcomes were gathered qualitatively via focus groups. The primary outcome was feasibility. The secondary outcomes were implementation outcomes according to the RE-AIM framework, including Reach, Effectiveness, Adoption and Implementation. RESULTS: Of 105 eligible children, 57 children and their parents participated (54%) with 31 (54%) girls, 47 (82%) Black/African American, 5 (9%) Hispanic and 5 (9%) white. The school staff implemented all planned ROcKET sessions with >90% fidelity in each session, and 52 (91%) of children who completed the final intervention session went on to complete 6 month follow-up assessments. The average attendance at the in-school child sessions was 57 students (87%), and 35 (61%) of parents attended at least one family session, with 25 (44%) of parents attending at least half of the family sessions. 13 (23%) parents participated in the focus groups. Qualitative data suggested high parent participant satisfaction, uptake of positive health behaviours targeted by the intervention and increased quality of life. CONCLUSIONS: Our study suggests that the ROcKET intervention was feasible and acceptably delivered in a local elementary school with high reach to low-income and minority populations. These data suggest that schools, especially those serving low-income and minority children, can be an appropriate avenue for interventions designed to address health disparities. Data from this study will be used to advise a pilot study of the intervention.

The Vanderbilt Nigeria Biostatistics Training Program (VN-BioStat): Results from a Skills Workshop.

The Vanderbilt-Nigeria Biostatistics Training Program (VN-BioStat) aims to establish a research and training platform for biostatisticians doing HIV-related research in Nigeria, including enhancing mid-level biostatistics capacity through annual workshops. This paper describes findings from the inaugural workshop in Kano, Nigeria. Participants were surveyed before and after the workshop to assess their self-perceived familiarity with and confidence in their abilities to use statistical software and apply specific statistical techniques, as well as to gather feedback regarding the conduct of the workshop and future topic areas. Of the 23 participants enrolled in the workshop, 22 (96%) completed both pre- and post-workshop assessments. In both pre-workshop and post-workshop surveys, participants ranked their confidence in statistical skills using Likert scales. Scores were transformed to a 0-100 scale, and averages computed. Participants also shared open-ended feedback about the workshop and suggested future topic areas. Before the training, the average participant reported having either a "beginner" (30% of participants) or "moderate" (43%) level of familiarity with R. Many participants (65%) rated themselves as having "moderate" or "expert" familiarity with SPSS. Pre-workshop averages for confidence ranged from 26 to 64, with lowest confidence in "expanding continuous covariates in regression models and interpret results" and highest confidence in "fitting and interpreting results from a linear regression model". Post-workshop averages for confidence were all above 70. The lowest post-workshop score (74) was for "fit and interpret results from a semiparametric linear transformation model". The greatest increase in confidence was observed in "expanding continuous covariates in regression models using splines and interpreting results" and the lowest increase was in "fitting and interpreting results from a linear regression model." Participants offered positive feedback on instructor effectiveness (4.9/5) and overall course quality (4.9/5). While the overall course was rated on a 0-100 scale as "moderately difficult" (mean ± SD: 40.5 ± 17.5), the participants felt the course was highly organized (87.7 ± 17.8), and the information was moderately easy to learn (81.9 ± 15.9). Suggestions for future workshops included providing supplementary resources for out-of-classroom learning and releasing codes in advance to enhance participants' preparation. Among suggestions for future workshop topics, 80% of respondents listed survival analysis. Lessons learned provide insight into how short-term training opportunities can be leveraged to build biostatistics capacity in similar settings.

Family resilience and childhood obesity among children exposed to adverse childhood experiences in a national survey.

OBJECTIVE: Adverse childhood experiences (ACEs) contribute to poor overall health among children with obesity. This study evaluated how one potential protective factor-family resilience-affects the association between ACEs and childhood obesity. METHODS: This analysis was a secondary analysis of the 2016-2018 National Survey of Children's Health (NSCH), a repeated cross-sectional survey based on parent report. Nine ACEs were queried. Family resilience was assessed with four items (potential range 0-12). The primary outcome was child weight status. Multivariable ordinal logistic regression was used, adjusting for potential confounders and the interaction between ACEs and family resilience. RESULTS: For 49,365 children ages 10-17, the median number of ACEs was 1 (IQR 0, 2), the median family resilience score was 10 (IQR 8,12), 15.3% of children had overweight, and 15.4% of children had obesity. Among the 51.3% of children who experienced one or more ACEs, higher family resilience scores attenuated the odds of being in a higher weight category. This pattern was not observed in children with zero ACEs. CONCLUSIONS: In the 2016-2018 NSCH, children ages 10-17 who were exposed to ACEs had higher rates of overweight and obesity, the odds of which may be reduced when children also have higher family resilience.

Competency-Based Approaches to Community Health: A Randomized Controlled Trial to Reduce Childhood Obesity among Latino Preschool-Aged Children.

Background: Health behavior change interventions that target childhood obesity in minority populations have led to inconsistent and short-lived results. The purpose of this study was to test a novel intervention that was personalized and family-based in a Latino population to reduce childhood obesity. Methods: Competency-Based Approaches to Community Health (COACH) was a randomized controlled trial. Latino parent-child pairs were recruited from community settings in Nashville, TN. Child eligibility criteria included age 3-5 years and a BMI ≥50th percentile. The intervention included 15 weekly, 90-minute sessions followed by 3 months of twice-monthly health coaching calls. The control group was a twice-monthly school readiness curriculum for 3 months. Sessions were conducted by a health coach in local community centers, with groups of 8-11 parent-child pairs. The primary outcome was child BMI trajectory across 12 months, measured at four times. The intervention's effect was assessed by using a longitudinal, linear mixed-effects growth model, adjusting for child gender, baseline child and parent age, and baseline parent BMI and education. Results: Of the 305 parent-child pairs assessed for eligibility, 117 were randomized (59 intervention, 58 control). Child BMI was available for 91.5% at 1-year follow-up. Mean baseline child age was 4.2 [standard deviation (SD) = 0.8] years, and 53.8% of children were female. Mean baseline child BMI was 18.1 (SD = 2.6) kg/m2. After adjusting for covariates, the intervention's effect on linear child BMI growth was -0.41 kg/m2 per year (95% confidence interval -0.82 to 0.01; p = 0.05). Conclusions: Over 1-year follow-up, the intervention resulted in slower linear BMI growth for Latino preschool-aged children from poverty.
