ABSTRACT

Information on how school-based programs is implemented and sustained during crises is limited. In this study, we assessed the impact of the COVID-19 pandemic on the implementation of a HIV prevention intervention in The Bahamas. Data were collected from 139 Grade 6 teachers in 2021-2022. Teachers attended virtual training and received implementation monitoring from coordinators. On average, teachers taught 26.4 (SD = 9.2) of the 35 core activities, and 7.4 (SD = 2.4) out of 9 sessions. More than half (58.3%) of teachers completed 28 or more core activities; 69.1% covered eight or all nine sessions, which is equivalent to 80% of the HIV intervention curriculum. Almost half of the teachers (43%) reported that the pandemic negatively impacted their ability to teach the program; 72% of teachers maintained that the program remained "very important" during times of crisis. Greater self-efficacy and supports increased implementation fidelity.

ABSTRACT

PURPOSE: To improve health equity, dental and medical students must have a firm grasp of the proper use of race as a social construct. The purpose of this study was to determine the degree to which an innovative learning event affected students' understanding of race as a social construct. It also sought to examine the effects that personally experienced and/or witnessed racism and previous education had on students' responses to the learning event. METHODS: In 2022, all incoming first-year dental (N = 48) and medical (N = 114) students completed an online pre-matriculation assignment about the use of race in healthcare. Students initially completed an anonymous 14-item pre-survey and then read assigned publications, followed by answering questions about a real-life vignette concerning the topic of race as a social construct. Students finished the assignment by completing an anonymous seven-item post-survey. Data from the pre- and post-surveys were collected and analyzed to assess if differences existed among students and between the two surveys. RESULTS: Dental and medical students were significantly more likely to endorse race as a social construct after the learning experience (p < 0.001). Students who had experienced discrimination or obtained training were more likely to define race as a social construct before and after the learning event. CONCLUSION: Dental and medical schools can increase students' understanding of race as a social construct, rather than a biological construct, with educational interventions.

ABSTRACT

Introduction: Adverse childhood experiences (ACEs) are associated with increased cancer risk. ACEs may affect this risk in a variety of ways, including cancer screening compliance. ACEs can contribute to mistrust in the medical profession, inhibit patient-provider relationships and cause at-risk individuals to miss critical access points to preventive services. Protective factors may play an important role in mitigating ACE-related consequences by supporting resiliency. Purpose: This study assesses the associations between ACEs, protective factors, patient-provider relationships, stage of cancer at diagnosis, and cancer screening behaviors for West Virginia (WV) cervical cancer survivors. Methods: WV cervical cancer survivors diagnosed between 2000 and 2020 were mailed a survey which included questions on demographic information and cancer screening behaviors, alongside three scales to measure depth of patient-provider relationships, ACEs, and protective factors. Results: Ninety participants completed the survey. ACEs were associated with weaker patient-provider relationships (p < .01) and fewer protective factors (p < .01). More protective factors were associated with stronger patient-provider relationships (p < .01), earlier stage of cancer at diagnosis (p < .05) and positive cancer screening behaviors. Positive cancer screening behaviors were associated with deeper patient-provider relationships (p < .05). A statistically significant model (p = .004) using ACE and resilience scores was able to account for 13% of the explained variability in depth of patient-provider relationships. Implications: These findings suggest an important interplay between ACEs, protective factors, and patient-provider relationships on cancer screening behaviors. Future studies should consider these variables in different populations. In addition, interventions focused on enhancing patient-provider relationships and supporting acquisition of protective factors should be considered.

ABSTRACT

Objective: To describe satisfaction with the telehealth aspect of a pediatric obesity intervention among families from multiple rural communities and assess differences in satisfaction based on sociodemographic factors. Methods: This is a secondary analysis of data from a pilot randomized controlled trial of a 6-month intensive lifestyle intervention (iAmHealthy) delivered through telehealth to children 6-11 years old with BMI ≥85th%ile and their parents from rural communities. Parents completed a sociodemographic survey and a validated survey to assess satisfaction with the telehealth intervention across four domains (technical functioning, comfort of patient and provider with technology and perceived privacy, timely and geographic access to care, and global satisfaction) on a 5-point Likert scale. Kruskal-Wallis nonparametric rank test were used to compare mean satisfaction scores based on parent sociodemographics. Results: Forty-two out of 52 parents (67% White, 29% Black, 5% multiracial, and 50% with household income <$40,000) completed the survey. Mean satisfaction scores ranged from 4.16 to 4.54 (standard deviation 0.44-0.61). Parents without a college degree reported higher satisfaction across all domains compared with parents with a college degree, including global satisfaction (mean 4.64 vs. 4.31, p = 0.03). Parents reporting a household income <$40,000 (mean 4.70) reported higher scores in the comfort with technology and perceived privacy domain compared with parents with higher incomes (mean 4.30-4.45, p = 0.04). Discussion: Parents from rural communities, especially those from lower socioeconomic backgrounds, were highly satisfied with the iAmHealthy telehealth intervention. These findings can be used to inform future telehealth interventions among larger more diverse populations. ClinicalTrials.gov Identifier: NCT04142034.

ABSTRACT

OBJECTIVES: (1) To evaluate the direct (un-mediated) and indirect (mediated) relationship between antenatal exposure to opioid agonist medication as treatment for opioid use disorder (MOUD) and the severity of neonatal opioid withdrawal syndrome (NOWS), and (2) to understand the degree to which mediating factors influence the direct relationship between MOUD exposure and NOWS severity. METHODS: This cross-sectional study includes data abstracted from the medical records of 1294 opioid-exposed infants (859 MOUD exposed and 435 non-MOUD exposed) born at or admitted to one of 30 US hospitals from July 1, 2016, to June 30, 2017. Regression models and mediation analyses were used to evaluate the relationship between MOUD exposure and NOWS severity (i.e., infant pharmacologic treatment and length of newborn hospital stay (LOS)) to identify potential mediators of this relationship in analyses adjusted for confounding factors. RESULTS: A direct (un-mediated) association was found between antenatal exposure to MOUD and both pharmacologic treatment for NOWS (aOR 2.34; 95%CI 1.74, 3.14) and an increase in LOS (1.73 days; 95%CI 0.49, 2.98). Delivery of adequate prenatal care and a reduction in polysubstance exposure were mediators of the relationship between MOUD and NOWS severity and as thus, were indirectly associated with a decrease in both pharmacologic treatment for NOWS and LOS. CONCLUSIONS FOR PRACTICE: MOUD exposure is directly associated with NOWS severity. Prenatal care and polysubstance exposure are potential mediators in this relationship. These mediating factors may be targeted to reduce the severity of NOWS while maintaining the important benefits of MOUD during pregnancy.

ABSTRACT

BACKGROUND: Natural disasters and public health crises can disrupt communities' capacities to implement important public health programs. A nationwide implementation of an evidence-based HIV prevention program, Focus on Youth in The Caribbean (FOYC) and Caribbean Informed Parents and Children Together (CImPACT), in The Bahamas was disrupted by Hurricane Dorian and the COVID-19 pandemic, especially in its more remote, Family Islands. We explored the teacher- and school-level factors that affected implementation of the program in these islands during those disruptions. METHODS: Data were collected from 47 Grade 6 teachers and 984 students in 34 government elementary schools during the 2020-2021 school year. Teachers completed a pre-implementation questionnaire to record their characteristics and perceptions that might affect their implementation fidelity and an annual program training workshop. School coordinators and high-performing teachers acting as mentors received additional training to provide teachers with monitoring, feedback, and additional support. Teachers submitted data on their completion of the 9 sessions and 35 core activities of FOYC + CImPACT. The fidelity outcomes were the number of sessions and core activities taught by teachers. RESULTS: On average, teachers taught 60% of sessions and 53% of core activities. Teachers with "very good" school coordinators (34% of teachers) taught more activities than those with "satisfactory" (43%) or no (34%) school coordinator (27.5 vs. 16.8 vs. 14.8, F = 12.86, P < 0.001). Teachers who had attended online training or both online and in-person training taught more sessions (6.1 vs. 6.2 vs. 3.6, F = 4.76, P < 0.01) and more core activities (21.1 vs. 20.8 vs. 12.6, F = 3.35, P < 0.05) than those who received no training. Teachers' implementation was associated with improved student outcomes (preventive reproductive health skills, self-efficacy, and intention). CONCLUSIONS: The Hurricane Dorian and the COVID-19 pandemic greatly disrupted education in The Bahamas Family Islands and affected implementation of FOYC + CImPACT. However, we identified several strategies that supported teachers' implementation following these events. Teacher training and implementation monitoring increased implementation fidelity despite external challenges, and students achieved the desired learning outcomes. These strategies can better support teachers' implementation of school-based interventions during future crises.

ABSTRACT

BACKGROUND: Effective implementation strategies are needed to address the challenges encountered by teachers in implementation of evidence-based HV prevention programs in schools. The current study: 1) compares implementation fidelity of Focus on Youth in the Caribbean (FOYC) plus Caribbean Informed Parents and Children Together (CImPACT) intervention using enhanced implementation strategies (including biweekly monitoring/feedback and site-based mentoring) to those using more traditional approach (teacher training only); and 2) evaluates the impact of school coordinators' and mentors' performance on teachers' implementation fidelity and student outcomes. METHODS: Data from an enhanced implementation trial in 2019-2020, involving 24 government primary schools, 79 teachers, and 2252 students, were compared to data from a standard implementation trial in 2011-2012, involving 35 government primary schools, 110 teachers and 2811 students using mixed-effects modeling and structural equation modeling. FINDINGS: Teachers in the 2019-2020 trial taught more core activities (28.3 vs. 16.3, t = 10.80, P < 0.001) and sessions (7.2 vs. 4.4, t = 9.14, P < 0.001) than those participating in the 2011-2012 trial. Teachers taught > 80% of the intervention curriculum in 2019-2020 compared to 50% curriculum delivery in 2011-2012. Teachers who had a "very good" or "excellent" school coordinator in their schools taught more core activities than those who had a "satisfactory" school coordinator (30.4 vs. 29.6 vs. 22.3, F = 18.54, P < 0.001). Teachers who worked in a school which had a "very good" mentor, taught more core activities than those teachers who did not have a mentor or had only a "satisfactory" mentor (30.4 vs. 27.6; t = 2.96; p = 0.004). Teachers' confidence in implementing core activities, comfort level with the curriculum, attitudes towards sex education in schools, and perceived principal support were significantly related to increased self-efficacy, which in turn was related to teachers' implementation fidelity. The degree of implementation was significantly associated with improved student outcomes. IMPLICATIONS/CONCLUSION: An evidence-based HIV prevention intervention can achieve a high degree of implementation when delivered with enhanced implementation strategies and implementation monitoring. Future program implementers should consider the purposeful selection and training of school coordinators and mentors to support low-implementing teachers as a potentially important strategy when attempting to achieve high-quality implementation of school-based interventions.

ABSTRACT

Children in rural settings are under-represented in clinical trials, potentially contributing to rural health disparities. We performed a scoping review describing available literature on barriers and facilitators impacting participation in pediatric clinical trials in rural and community-based (nonclinical) settings. Articles identified via PubMed, CINAHL, Embase, and Web of Science were independently double-screened at title/abstract and full-text levels to identify articles meeting eligibility criteria. Included articles reported on recruitment or retention activities for US-based pediatric clinical studies conducted in rural or community-based settings and were published in English through January 2021. Twenty-seven articles describing 31 studies met inclusion criteria. Most articles reported on at least one study conducted in an urban or suburban or unspecified community setting (n = 23 articles; 85%); fewer (n = 10; 37%) reported on studies that spanned urban and rural settings or were set in rural areas. More studies discussed recruitment facilitators (n = 25 studies; 81%) and barriers (n = 19; 61%) versus retention facilitators (n = 15; 48%) and barriers (n = 8; 26%). Descriptions of recruitment and retention barriers and facilitators were primarily experiential or subjective. Recruitment and retention facilitators were similar across settings and included contacts/reminders, community engagement, and relationship-building, consideration of participant logistics, and incentives. Inadequate staff and resources were commonly cited recruitment and retention barriers. Few studies have rigorously examined optimal ways to recruit and retain rural participants in pediatric clinical trials. To expand the evidence base, future studies examining recruitment and retention strategies should systematically assess and report rurality and objectively compare relative impact of different strategies.

ABSTRACT

BACKGROUND: Effective implementation strategies are needed to enhance the success of evidence-based prevention programs. The current study evaluates the effects of two implementation strategies on teachers' implementation of an evidenced-based HIV intervention. METHODS: Using our 7-item pre-implementation school screening tool, we identified teachers who were at-risk for not implementing the Focus on Youth HIV-risk reduction intervention curriculum which targets grade six through grade 8 students. After completing a two-day curriculum workshop, 81 low- and moderate-performing teachers were randomly assigned to one of four experimental conditions and were asked to teach the two-month intervention curriculum. This optimization trial examines the impact of two implementation strategies: biweekly monitoring/feedbacks (BMF) and site-based assistance/mentorship (SAM). The primary outcome is implementation fidelity defined as number of core activities taught. Linear mixed-effects model was used to examine the association of the implementation strategies with implementation fidelity. RESULTS: BMF and SAM were significantly associated with teachers' implementation fidelity. Teachers who received both BFM and SAM taught the greatest numbers of core activities (15 core activities on average), followed by teachers who received either BMF (6.9 activities) or SAM (7.9 activities). Teachers who did not receive BMF or SAM taught the lowest numbers (4.1 activities). Teachers' sustained implementation of FOYC in the prior school year was related to increased implementation fidelity during the optimization trial. Teachers' confidence in implementing five core activities, attitudes toward sex education in schools, and perceived principal support were significantly related to increased self-efficacy, which in turn was related to teachers' fidelity of implementation before the optimization trial. CONCLUSION: BMF and SAM are effective in promoting teachers' implementation of youth evidence-based interventions. Researchers and future program implementers should consider teacher training, teachers' attitudes toward sex education, perceived principal support, and self-efficacy when attempting to maintain the effects of teacher-delivered interventions in schools.

ABSTRACT

INTRODUCTION: Despite national efforts to establish patient-centered medical homes (PCMH), 57.3% of children with special health care needs are receiving care that does not meet medical home criteria. Project DOCC, a national curriculum designed by parents of children with disabilities or chronic disease, has shown documented strengths in medical resident learner education of children with special health care needs from the parent perspectives for over a decade. Because of the importance of PCMH and the need to provide compassionate care, our team adapted the curriculum to incorporate team-based learning in the rural setting. MATERIALS AND METHODS: Reading materials were distributed to learners prior to an in-person workshop at which time, learners reviewed a video and discussed PCMH materials to identify elements of the PCMH. Learners then engaged with parent mentors across three breakout sessions. A final group reflection was completed to review and discuss efforts providers would take to establish and maintain the PCMH in their own practice. Baseline and post-workshop PCMH perceptions and parent mentor reflections were collected and compared using t-test comparisons. RESULTS: Learner knowledge, perceptions, and comfort significantly increased after the workshop. Parent mentor comments also highlighted an increased understanding for the provider. Discussion: The adapted PCMH curriculum significantly impacted learner outcomes using a feasible approach that fit nicely within health professional curricula and limited resources of the rural setting. Parents enjoyed the opportunity to serve as mentors and valued the instruction format.

ABSTRACT

OBJECTIVE: Diagnosis-related groups (DRGs) are used to summarize hospital morbidity and mortality. Each DRG has a weight which is important in calculating the case mix index (CMI), a numeric summary of disease complexity in a population of patients. We utilized DRG weight and resultant CMI to compare postnatal outcomes among singletons versus monochorionic and monoamniotic, monochorionic diamniotic, and dichorionic diamniotic twins. STUDY DESIGN: This single-center and retrospective cohort study evaluated DRGs assigned by the investigators, birth weight, gestational age, length of stay (LOS), NICU admission rate, and mortality in twin births between 2014 and 2016. Twins were analyzed depending on chorionicity and amnionicity. Overall, 3 months of singleton births served as the control. The CMI derived from DRG weights were compared across groups. RESULTS: Twins (n = 288) had lower gestational ages and birth weights and higher mortality, LOS, NICU admission rates and DRG weights/CMI compared with singletons (n = 327; p < 0.001 for each). The LOS was no different between twin subtypes; monochorionic monoamniotic twins had the highest mortality and DRG weight (p < 0.001). CONCLUSION: DRG weight and CMI values summarize in-hospital complexity and can be a useful tool to evaluate differences in care complexity among groups of patients. KEY POINTS: · Using diagnosis-related group and case mix index to assess morbidities.. · Morbidities of twins are monochorionic-monoamniotic versus monochorionic-diamniotic versus dichorionic-diamniotic twins.. · Only seven diagnosis-related group in neonatology make it a valuable tool for clinicians..

ABSTRACT

OBJECTIVE: This study examined the association between preconception substance use and unintended pregnancy in a large, nationally representative sample of women. METHODS: In this cross-sectional study, we used data from the Pregnancy Risk Assessment Monitoring System (PRAMS) comprising, 74,543women who had birth during 2016-17. Logistic regression was used to assess the independent association of unintended pregnancy overall and by subtypes to preconception substance use (smoking and other nicotine/tobacco use, alcohol consumption, and use of cannabis, illicit/recreational drugs) and specific medication including prescription opioids, antidepressants and over the counter pain relief. RESULTS: Overall, 41% of pregnancies were unintended. Nearly 57% of participants reported alcohol consumption during the preconception period, with 32% indicating binge drinking, 17% reported preconception smoking, and 10% cannabis use. Unintended pregnancy was significantly associated with substance use, including smoking (adjusted odds ratio [AOR]:1.5, 95% confidence interval [CI]: 1.4-1.6); as well as the use of other nicotine/tobacco (AOR:1.4, 95% CI: 1.3-1.5); cannabis (AOR: 1.9, 95% CI: 1.5-2.3); illicit/recreational drugs (AOR:1.7, 95% CI: 1.2-2.4), prescription opioids (AOR:1.4, 95% CI: 1.02-1.9), and prescription antidepressants (AOR 1.8, 95% CI: 1.1-3.0). The likelihood of unintended pregnancy was significantly elevated with heavy smoking, heavy alcohol consumption, and binge drinking. Analyses by unintended pregnancy subtype yielded similar results. CONCLUSIONS: Preconception substance use was significantly and positively associated with unintended pregnancy. Evidence-based interventions are needed addressing substance use behavior and effective contraceptive use to prevent unintended pregnancy and related adverse effects on maternal and child health.

ABSTRACT

BACKGROUND: Studies suggest that exposure to ambient air pollution during pregnancy may be associated with increased risks of birth defects (BDs), but conclusions have been inconsistent. This study describes the ethnic distribution of major BDs and examines the relationship between air pollution and BDs among different ethnic groups in Liuzhou city, China. METHODS: Surveillance data of infants born in 114 registered hospitals in Liuzhou in 2019 were analyzed to determine the epidemiology of BDs across five major ethnic groups. Concentrations of six air pollutants (PM2.5, PM10, SO2, CO, NO2, O3) were obtained from the Liuzhou Environmental Protection Bureau. Logistic regression was used to examine the associations between ambient air pollution exposure and risk of BDs. RESULTS: Among 32,549 infants, 635 infants had BDs, yielding a prevalence of 19.5 per 1000 perinatal infants. Dong ethnic group had the highest prevalence of BDs (2.59%), followed by Yao (2.57%), Miao (2.35%), Zhuang (2.07%), and Han (1.75%). Relative to the Han ethnic group, infants from Zhuang, Miao, Yao and Dong groups had lower risks of congenital heart disease, polydactyly, and hypospadias. The Zhuang ethnic group had higher risks of severe thalassemia, cleft lip and/or palate, and syndactyls. Overall BDs were positively correlated with air pollutants PM10 (aOR =1.14, 95% CI:1.12 ~ 2.43; aOR =1.51, 95% CI:1.13 ~ 2.03 for per 10µg/mg3 increment) and CO (aOR =1.36, 95% CI:1.14 ~ 2.48; aOR =1.75, 95% CI:1.02 ~ 3.61 for every 1 mg /m3 increment) in second and third month of pregnancy. SO2 was also significantly associated with BDs in the second month before the pregnancy (aOR = 1.31; 95% CI: 1.20 ~ 3.22) and third month of pregnancy (aOR =1.75; 95% CI:1.02 ~ 3.61). Congenital heart disease, polydactyl, cleft lip and/or palate were also significantly associated with PM10, SO2 and CO exposures. However, no significant association was found between birth defects and O3, PM2.5 and NO2 exposures (P > 0.05). CONCLUSION: This study provides a comprehensive description of ethnic differences in BDs in Southwest China and broadens the evidence of the association between air pollution exposure during gestation and BDs.

ABSTRACT

BACKGROUND: Precision prevention is increasingly important in HIV prevention research to move beyond universal interventions to those tailored for high-risk individuals. The current study was designed to develop machine learning algorithms for predicting adolescent HIV risk behaviours. METHODS: Comprehensive longitudinal data on adolescent risk behaviours, perceptions, peer and family influence, and neighbourhood risk factors were collected from 2564 grade-10 students at baseline followed for 24 months over 2008-2012. Machine learning techniques [support vector machine (SVM) and random forests] were applied to innovatively leverage longitudinal data for robust HIV risk behaviour prediction. In this study, we focused on two adolescent risk behaviours: had ever had sex and had multiple sex partners. Twenty percent of the data were withheld for model testing. RESULTS: The SVM model with cost-sensitive learning achieved the highest sensitivity, at 79.1%, specificity of 75.4% with AUC of 0.86 in predicting multiple sex partners on the training data (10-fold cross-validation), and sensitivity of 79.7%, specificity of 76.5% with AUC of 0.86 on the testing data. The random forest model obtained the best performance in predicting had ever had sex, yielding the sensitivity of 78.5%, specificity of 73.1% with AUC of 0.84 on the training data and sensitivity of 82.7%, specificity of 75.3% with AUC of 0.87 on the testing data. CONCLUSION: Machine learning methods can be used to build effective prediction model(s) to identify adolescents who are likely to engage in HIV risk behaviours. This study builds a foundation for targeted intervention strategies and informs precision prevention efforts in school-setting.

ABSTRACT

BACKGROUND AND OBJECTIVES: Variation in pediatric medical care is common and contributes to differences in patient outcomes. Site-to-site variation in the characteristics and care of infants with neonatal opioid withdrawal syndrome (NOWS) has yet to be quantified. Our objective was to describe site-to-site variation in maternal-infant characteristics, infant management, and outcomes for infants with NOWS. METHODS: Cross-sectional study of 1377 infants born between July 1, 2016, and June 30, 2017, who were ≥36 weeks' gestation, with NOWS (evidence of opioid exposure and NOWS scoring within the first 120 hours of life) born at or transferred to 1 of 30 participating hospitals nationwide. Site-to-site variation for each parameter within the 3 domains was measured as the range of individual site-level means, medians, or proportions. RESULTS: Sites varied widely in the proportion of infants whose mothers received adequate prenatal care (31.3%-100%), medication-assisted treatment (5.9%-100%), and prenatal counseling (1.9%-75.5%). Sites varied in the proportion of infants with toxicology screening (50%-100%) and proportion of infants receiving pharmacologic therapy (6.7%-100%), secondary medications (1.1%-69.2%), and nonpharmacologic interventions including fortified feeds (2.9%-90%) and maternal breast milk (22.2%-83.3%). The mean length of stay varied across sites (2-28.8 days), as did the proportion of infants discharged with their parents (33.3%-91.1%). CONCLUSIONS: Considerable site-to-site variation exists in all 3 domains. The magnitude of the observed variation makes it unlikely that all infants are receiving efficient and effective care for NOWS. This variation should be considered in future clinical trial development, practice implementation, and policy development.

ABSTRACT

Child sexual abuse is a severely underreported crime in the United States. The consequences of child sexual abuse extend beyond physical injury, including an increased likelihood to develop chronic physical and mental diseases/disorders, including substance abuse and suicide. Care involves trauma-informed screening, assessment, and documentation, education of, and access to sexually transmitted infection prophylaxis and emergency contraception, safety interventions, and access to community resources. Medical providers should know the response process their facility, community, and state practices for victims of sexual abuse.

ABSTRACT

The reported associations between birth weight and childhood cardiovascular disease (CVD) risk factors have been inconsistent. In this study, we investigated the relationship between birth weight and CVD risk factors at 11 years of age. This study used longitudinally linked data from three cross-sectional datasets (N = 22,136) in West Virginia; analysis was restricted to children born full-term (N = 19,583). The outcome variables included resting blood pressure [systolic blood pressure (SBP), diastolic blood pressure (DBP)] and lipid profile [total cholesterol (TC), low-density lipoprotein (LDL) cholesterol, high-density lipoprotein (HDL) cholesterol, non-HDL, and triglycerides (TG)]. Multiple regression analyses were performed, adjusting for child's body mass index (BMI), sociodemographics, and lifestyle characteristics. Unadjusted analyses showed a statistically significant association between birth weight and SBP, DBP, HDL, and TG. When adjusted for the child's BMI, the association between birth weight and HDL [b = 0.14 (95% CI: 0.11, 0.18) mg/dl per 1000 g increase] and between birth weight and TG [b = -0.007 (-0.008, -0.005) mg/dl per 1000 g increase] remained statistically significant. In the fully adjusted model, low birth weight was associated with higher LDL, non-HDL, and TGs, and lower HDL levels. The child's current BMI at 11 years of age partially (for HDL, non-HDL, and TG) and fully mediated (for SBP and DBP) the relationship between birth weight and select CVD risk factors. While effects were modest, these risk factors may persist and amplify with age, leading to potentially unfavorable consequences in later adulthood.

ABSTRACT

An Exploratory Study on the Intergenerational Transmission of Dieting Proneness within an Eating Disorder Population (IRB Protocol Number: 160928271). PURPOSE: Parents and families are not the sole factor in eating disorder (ED) development and their involvement in recovery is crucial. However, parents provide a social and environmental context for a child's eating and weight that cannot be completely discounted. The purpose of this study was to explore the intergenerational transmission of dieting behavior within an ED sample. METHODS: Participants (N = 65) were recruited for this cross-sectional study through four distinct ED treatment sites. Participants completed a questionnaire that was developed previously to examine parental feedback as predictor variables, as well as completing the Eating Pathology Severity Index (EPSI) as an outcome variable. A total of 60 completed the questionnaire items of interest to be included in the analyses. SAS JMP® 13.0 was used for descriptive analyses, correlations, and multivariable linear regressions. RESULTS: Results of the multivariable linear regression showed that the amount of variance explained by the final model for eating pathology severity (via the EPSI) doubled when parental feedback was included (Model 1: R2= 0.09, Model 2: R2= 0.20). Additionally, there was a significant relationship between the "Negative Direct Parental Feedback Subscale" and EPSI total scores (ß = 14.1; SD = 7.0; p = 0.05). CONCLUSION: These findings of increased eating pathology associated with direct parental feedback in a clinical population of ED participants even when controlling for parental ED history suggests greater attention is needed within the ED literature on social and environmental factors and their potential associations with eating pathology. LEVEL OF EVIDENCE: Level V, descriptive study.

ABSTRACT

BACKGROUND: Public health experts recommend school-based policies as a population based approach to increase youth physical activity. The purpose of this case study is to describe one, largely rural, state's efforts to translate this recommendation into practice. Details about the genesis, implementation and evolution of two state level policies (physical education and physical activity), as well as in-house efforts of a State Department of Education to monitor policy compliance and challenges encountered are described. Two specific years are highlighted, due to policy and monitoring enhancements made during those particular time periods. METHODS: Data for this paper come from the West Virginia Department of Education for two time periods: 2013-2014 and 2014-2015 (n=369 elementary schools). Descriptive statistics for quantitative data and content analysis for qualitative data were used to document school level compliance and provide context for implementation challenges. RESULTS: Greater than 70% of school principals reported achievement of physical education and physical activity policy expectations for each year. Limited staff was the predominant explanation for nonfulfillment of physical education expectations, followed by lack of time and facilities. Recess and classroom-based physical activity were the primary strategies used to comply with the physical activity expectations. PE and PA policy compliance varied significantly by certain school characteristics in each school year studied. CONCLUSIONS: Further investigation is warranted on how states translate public health policy recommendations into practice, including how physical education and physical activity policies are developed and monitored at the state level and how to support states and schools with monitoring and implementation challenges.
