Background: Weight misperception is a common problem among adolescents; how­ever, few studies have examined contribut­ing factors among an exclusively African American population. The purpose of this study was to examine factors associated with weight misperception among 12- to 19-year-old participants in the Jackson Heart KIDS Pilot Study (JHS-KIDS).Methods: Data were drawn from JHS-KIDS, a prospective, observational examination of cardiovascular-related risk factors among African American adolescents who were children or grandchildren of participants in the Jackson Heart Study. Adolescent weight misperception – discordance between mea­sured weight status and perceived weight status – was the primary outcome of inter­est. Self-reported weight control behaviors, parent concerns about adolescents' weight, parent-perceived responsibility for adoles­cent's weight and daily hassles were the primary independent variables of interest.Results: The analytic sample was equally divided by females (n=107) and males (n=105) and one third of study partici­pants (33.5%) had discordance between their actual and perceived weight. Results from fully adjusted sex-stratified modified Poisson regression models indicated that weight behavior control was significant among females (PR = .66, 95%CI:1.20- 2.30). Parental concerns about child weight were significant for males. Each additional point increase in the parent's concern about their weight score was associated with a 9% increase in the adjusted prevalence of weight misperception among males (95%CI: 1.03-1.16).Conclusions: The sex-specific patterns in this study highlight heterogeneity among African American adolescents and an urgent need to consider sex and gender when developing targeted interventions for youth who are at high risk for weight misper­ceptions and unhealthy weight control practices.

Background: Eliminating the NIH fund­ing gap among underrepresented minori­ties (URMs) remains a high priority for the National Institutes of Health. In 2014, the National Research Mentoring Network1 Steps Toward Academic Research (NRMN STAR) program recruited postdoctoral, early-stage and junior faculty to participate in a 12-month grant writing and professional development program. The expectation of the program was to increase the number of grant submissions and awards to URM re­searchers. Although receiving a grant award is the gold standard of NRMN STAR, instill­ing confidence for postdocs and early-stage faculty to submit an application is a critical first step. Based on our previous study, a sustained increase in trainee self-efficacy score over a 24-month period was observed after completing NRMN STAR.Methods: The current study sought to determine the association between self-efficacy score and grant submissions among two cohorts of trainees. Grantsmanship Self-Efficacy was measured using a 19-item questionnaire previously described by and used in our own work, which was originally adapted from an 88-item Clinical Research Appraisal Inventory.2 A binary variable was created to identify trainees who submit­ted an initial or revised proposal vs those who abandoned their proposal or were still writing. Trainees were assessed prior to and following program completion with subsequent assessments at 6 and 12 months beyond participation.Results: As of June 20, 2019, 12 of the 21 (57%) trainees had submitted a grant proposal (eg, NIH, other federal or non-federal grant). For every point increase in 12-month post assessments, Grantsmanship Self-Efficacy scores across all domains had a 44% higher prevalence of submitting a grant after controlling for race, sex, education level, academic rank, research experience, duration of postdoctoral training, institution type, and NRMN STAR cohort. Conclusions: Our findings demonstrate that NRMN STAR had a positive impact on trainees' confidence in grant writing and professional development activities, which resulted in higher grant submis­sion rates.Ethn Dis. 2021;31(4):559-566; doi:10.18865/ed.31.4.559

Background: African American children and adolescents make up a disproportion­ately large segment of those classified as overweight and obese. The purpose of this study was to examine social and behavioral factors associated with accelerated ac­cumulation of weight and adiposity among this group.Methods: The data for this cross-sectional study were drawn from the Jackson Heart KIDS Pilot Study – an offspring cohort study comprising 12- to 19-year-old descen­dants of Jackson Heart Study participants (N=212). Body mass index (BMI) and waist circumference were the outcomes of interest. Daily hassles, fruit and vegetable consumption, physical activity, television watching, parent/grandparent weight status and participant birth weight, age and sex were the independent variables included in the analyses.Results: Males and females were equally represented in the study and the mean BMI and waist circumference for adolescents in the study was 25.81±7.78 kg/m2 and 83.91 ± 19.81 cm, respectively. Fully adjusted linear regression models for the total sample produced results indicating that age, televi­sion viewing, weight control, and parental weight status were positively associated with BMI and waist circumference, respectively. Findings from sex-stratified models for BMI and waist circumference indicated that the significance of coefficients for age, television viewing, and parent/grandparent weight status varied by sex.Conclusions: Knowledge is limited about how sex or gender interact with social and behavioral factors to influence African Americans' health and additional studies are needed to specify how these factors interact to accelerate weight gain and adipose tissue accumulation over the life course.Ethn Dis. 2021;31(3):453-460; doi:10.18865/ed.31.3.453

The NRMN STAR program was created to address the persistent underrepresenta­tion in grant submissions and receipt of National Institutes of Health (NIH) awards by racial/ethnic minority groups. In our current study, we assessed program impact on trainees' self-efficacy related to grant writing. The program was conducted with two cohorts: one in June 2014 and one in June 2015. We used a 19-item grant writing self-efficacy scale drawn from the 88-item Clinical Research Assessment Inventory of three domains (conceptualizing, designing, and funding a study) to predict whether self-efficacy influences researchers' grant submissions. Trainees were assessed prior to and following program completion with subsequent assessments at 6 and 12 months beyond participation. The majority of trainees were Black (62%), female (62%), and had obtained a PhD (90%). More than half (52%) were assistant professors and 57% had none or <1 year of research experience beyond postdoctoral training. However, 24% of trainees reported no postdoctoral research training. NRMN STAR trainees' self-efficacy significantly improved on all three domains exhibiting a 2.0-point mean change score on two domains (conceptualizing and design) and 3.7 point mean change score on the domain, funding a study. Findings suggest that NRMN's STAR provides impactful, confidence-building training for diverse, early stage investigators with little-to-no skills, experiences, or low self-efficacy in writing research grants.
