RESUMO

Venetoclax (VEN) in combination with hypomethylating agents induces disease remission in patients with de novo AML, however, most patients eventually relapse. AML relapse is attributed to the persistence of drug-resistant leukemia stem cells (LSCs). LSCs need to maintain low intracellular levels of reactive oxygen species (ROS). Arsenic trioxide (ATO) induces apoptosis via upregulation of ROS-induced stress to DNA-repair mechanisms. Elevated ROS levels can trigger the Nrf2 antioxidant pathway to counteract the effects of high ROS levels. We hypothesized that ATO and VEN synergize in targeting LSCs through ROS induction by ATO and the known inhibitory effect of VEN on the Nrf2 antioxidant pathway. Using cell fractionation, immunoprecipitation, RNA-knockdown, and fluorescence assays we found that ATO activated nuclear translocation of Nrf2 and increased transcription of antioxidant enzymes, thereby attenuating the induction of ROS by ATO. VEN disrupted ATO-induced Nrf2 translocation and augmented ATO-induced ROS, thus enhancing apoptosis in LSCs. Using metabolic assays and electron microscopy, we found that the ATO+VEN combination decreased mitochondrial membrane potential, mitochondria size, fatty acid oxidation and oxidative phosphorylation, all of which enhanced apoptosis of LSCs derived from both VEN-sensitive and VEN-resistant AML primary cells. Our results indicate that ATO and VEN cooperate in inducing apoptosis of LSCs through potentiation of ROS induction, suggesting ATO+VEN is a promising regimen for treatment of VEN-sensitive and -resistant AML.

RESUMO

Electronic cigarette (e-cigarette) use, or vaping, among youth and young adults has become a major public health concern. The prevalence of vaping has grown an astounding 900% among high school students from 2011 to 2015, and e-cigarette use among high school students has increased by 78% from 2017 to 2018, largely due to the rise in popularity of the high-dose nicotine product, JUUL. To date, there are few evidence-based e-cigarette cessation programs. To address this need, the South Texas Oral Health Network collaborated with dental practitioners and community members to conduct focus groups assessing knowledge and awareness of e-cigarette use. Based on this feedback, we developed a dental practitioner-based e-cigarette cessation program. The next step will be to utilize this program in a practice-based research network, a "real-world" practice setting that has the potential to increase the number of dental practitioners who counsel their patients about ecigarettes.

RESUMO

BACKGROUND: Improvement in hypertension control in the insured, adult population could improve morbidity and mortality associated with hypertension in the United States. The emergency department (ED) is a potential site of intervention, where individuals are diagnosed with asymptomatic hypertension and referred to primary care. OBJECTIVE: To inform intervention strategies, we identified risk factors of nonadherence to primary care follow-up among individuals aged 18-60 years with a primary discharge diagnosis of asymptomatic hypertension in the ED. METHODS: Data were obtained from a commercial claims database for January 2012-September 2015. A total of 84,929 individuals were included. Rate of nonadherence to primary care follow-up was determined for individuals billed for a primary discharge diagnosis of essential hypertension. Multivariate logistic regression was used to calculate adjusted odds ratios. The relationships between demographic and clinical variables with nonadherence to follow-up were assessed. RESULTS: Two-thirds of the study population did not adhere to follow-up within 30 days of ED discharge. Risk factors for nonadherence included no history of recent visit with primary care (odds ratio [OR] 1.87; 95% confidence interval [CI] 1.81-1.93) and multiple prior ED visits (OR 1.65; 95% CI 1.57-1.73). Protective characteristics included history of filling antihypertensive prescriptions in the last year (OR 0.42; 95% CI 0.40-0.43); or history of filling a 30-day antihypertensive prescription on day of diagnosis (OR 0.83; 95% CI 0.80-0.87). CONCLUSIONS: Individuals without a recent primary care visit or who visit the ED frequently are at higher risk of nonadherence to follow-up for hypertension, despite medical insurance. Insurance status may not overcome individual level barriers to follow-up.

RESUMO

OBJECTIVES: To evaluate chronic pain management in a multistate, low-income Hispanic population, and to examine predictors of exercising and prescription pain medication (PPM) use. DESIGN: Online survey administered to a representative sample of Hispanic adults in June 2015. SETTING: Five southwestern states. PARTICIPANTS: Among all online panel members who were Hispanic (N=1007), aged 35 to 75 years from 5 states, representing 11,016,135 persons, the survey was completed by 516 members (51%). Among these, 102 participants were identified with chronic noncancer pain representing 1,140,170 persons. INTERVENTIONS: Not applicable. MAIN OUTCOME MEASURES: Exercising or using PPM for chronic pain in past year. RESULTS: Most participants reported using PPM (58%) and exercise (54%) to manage pain. Compared with annual household incomes >$75,000, adjusted odds ratios [AORs] for exercising were .20 for <$10,000 (P=.12); .40 for $10,000 to $34,999 (P=.22); and .15 for $35,000 to $74,999 (P=.015). Conversely, AORs for PPM were over 4-fold higher for lower-income groups as follows: 14.2, 4.79, and 4.85, respectively (all P<.065). PPM users rated the importance of accessing a gym to manage pain lower (P=.01), while exercisers rated the feasibility of gym access to manage pain higher (P=.001). CONCLUSIONS: In a Hispanic population-based sample with chronic pain, lower-income groups tended to exercise less but use PPM more. Barriers to gym access and use may play a role in these disparities.

RESUMO

BACKGROUND: Effective community-partnered and patient-centered outcomes research needs to address community priorities. However, optimal sampling methods to engage stakeholders from hard-to-reach, vulnerable communities to generate research priorities have not been identified. METHODS: In two similar rural, largely Hispanic communities, a community advisory board guided recruitment of stakeholders affected by chronic pain using a different method in each community: 1) snowball sampling, a chain- referral method or 2) purposive sampling to recruit diverse stakeholders. In both communities, three groups of stakeholders attended a series of three facilitated meetings to orient, brainstorm, and prioritize ideas (9 meetings/community). Using mixed methods analysis, we compared stakeholder recruitment and retention as well as priorities from both communities' stakeholders on mean ratings of their ideas based on importance and feasibility for implementation in their community. RESULTS: Of 65 eligible stakeholders in one community recruited by snowball sampling, 55 (85 %) consented, 52 (95 %) attended the first meeting, and 36 (65 %) attended all 3 meetings. In the second community, the purposive sampling method was supplemented by convenience sampling to increase recruitment. Of 69 stakeholders recruited by this combined strategy, 62 (90 %) consented, 36 (58 %) attended the first meeting, and 26 (42 %) attended all 3 meetings. Snowball sampling recruited more Hispanics and disabled persons (all P < 0.05). Despite differing recruitment strategies, stakeholders from the two communities identified largely similar ideas for research, focusing on non-pharmacologic interventions for management of chronic pain. Ratings on importance and feasibility for community implementation differed only on the importance of massage services (P = 0.045) which was higher for the purposive/convenience sampling group and for city improvements/transportation services (P = 0.004) which was higher for the snowball sampling group. CONCLUSIONS: In each of the two similar hard-to-reach communities, a community advisory board partnered with researchers to implement a different sampling method to recruit stakeholders. The snowball sampling method achieved greater participation with more Hispanics but also more individuals with disabilities than a purposive-convenience sampling method. However, priorities for research on chronic pain from both stakeholder groups were similar. Although utilizing a snowball sampling method appears to be superior, further research is needed on implementation costs and resources.

RESUMO

OBJECTIVE: This exploratory study assessed health literacy among urban African-American high school students to improve understanding of the association between adolescent health literacy and asthma. METHODS: We conducted a secondary data analysis of the control group (n = 181) of the Puff City randomized controlled trial (2006-2010), a web-based intervention to promote asthma management among students, grades 9 through 12. A validated self-report 3-item health literacy screening instrument was completed at final online follow-up survey. Logistic regression was used to explore the association between health literacy, demographic characteristics, quality of life, asthma management, and health care utilization. RESULTS: Multivariate analysis revealed that an overall inadequate health literacy score was associated with students who were more likely to be younger (OR 0.61; 95% CI 0.44-0.84), not on Medicaid (OR 0.36; 95% CI 0.17-0.76), have at least one hospitalization (OR 1.29; 95% CI 1.07-1.56); and a lower overall quality of life (OR 0.75; 95% CI 0.59-0.95). Those lacking confidence in filling out medical forms, needing help reading hospital materials, and having difficulty understanding written information were more likely to not have a rescue inhaler (OR 0.49; 95% CI 0.25-0.94), have one or more emergency visits (OR 1.21 95% CI 1.02-1.43), and one or more hospitalizations (OR 1.19; 95% CI 1.01-1.41), respectively. CONCLUSIONS: The findings indicate a significant association between inadequate health literary and suboptimal asthma management. It is important to advance understanding of adolescent health literacy, especially those at-risk, as they assume asthma self-management tasks and move toward independent adult self-care.

RESUMO

BACKGROUND: Patients with limited English proficiency (LEP) may be at risk for medical errors and worse health outcomes. Language concordance between patient and provider has been shown to improve health outcomes for Spanish-speaking patients. Nearly 40 % of Hispanics, a growing population in the United States, are categorized as having limited English proficiency. Many medical schools have incorporated a medical Spanish curriculum to prepare students for clinical encounters with LEP patients. OBJECTIVE: To describe the current state of medical Spanish curricula at United States medical schools. METHODS: The Latino Medical Student Association distributed an e-mail survey comprising 39 items to deans from each U.S. medical school from July 2012 through July 2014. This study was IRB-exempt. RESULTS: Eighty-three percent (110/132) of the U.S. medical schools completed the survey. Sixty-six percent (73/110) of these schools reported offering a medical Spanish curriculum. In addition, of schools with no curriculum, 32 % (12/37) planned to incorporate the curriculum within the next two years. Most existing curricula were elective, not eligible for course credit, and taught by faculty or students. Teaching modalities included didactic instruction, role play, and immersion activities. Schools with the curriculum reported that the diverse patient populations in their respective service areas and/or student interest drove course development. Barriers to implementing the curriculum included lack of time in students' schedules, overly heterogeneous student language skill levels, and a lack of financial resources. Few schools reported the use of validated instruments to measure language proficiency after completion of the curriculum. CONCLUSIONS: Growing LEP patient populations and medical student interest have driven the implementation of medical Spanish curricula at U.S. medical schools, and more schools have plans to incorporate this curriculum in the near future. Studies are needed to reveal best practices for developing and evaluating the curriculum.

RESUMO

This article aimed to provide a descriptive review of the psychometric properties and conceptual dimensions of published health literacy measurement tools. PsycINFO and PubMed search from 1999 through 2013, review of the grey literature, and an environmental scan was conducted to identify health literacy measurement tools. For each tool, we evaluated the conceptual dimensions assessed, test parameters, and psychometric properties. Of the 51 tools identified, 26 measured general health literacy, and 15 were disease or content specific, and 10 aimed at specific populations. Most tools are performance based, require in-person administration, and are exclusively available in a pencil and paper testing mode. The tools assess 0 (proxy measure) to 9 of the 11 defined dimensions of health literacy. Reported administration times vary, from less than 1 to 60 minutes. Validation procedures for most of the tools are limited by inadequate power to ensure reliability across subgroups (i.e., race, age, ethnicity, and gender). The health literacy measurement tools currently available generally represent a narrow set of conceptual dimensions with limited modes of administration. Most of the tools lack information on key psychometric properties. Significant work is needed to establish important aspects of the construct, convergent, and predictive validity for many tools. As researchers develop new measures, inclusion of a full range of conceptual dimensions of health literacy, more representative sampling for testing, and additional modes of administration will allow a more refined and flexible approach to research in this field.

RESUMO

BACKGROUND: Early T cell precursor acute lymphoblastic leukemia (ETP-ALL) is a distinct subtype of T-ALL with a poor prognosis. To find a cure, we examined the synergistic effect of homoharringtonine (HHT) in combination with the BCL-2 inhibitor venetoclax (VEN) in ETP-ALL. METHODS: Using in vitro cellular assays and ETP-ALL xenograft models, we first investigated the synergistic activity of HHT and VEN in ETP-ALL. Next, to explore the underlying mechanism, we employed single-cell RNA sequencing of primary ETP-ALL cells treated with HHT or VEN alone or in combination and validated the results with western blot assays. Based on the promising preclinical results and given that both drugs have been approved for clinical use, we then assessed this combination in clinical practice. FINDINGS: Our results showed that HHT synergizes strongly with VEN both in vitro and in vivo in ETP-ALL. Mechanistic studies demonstrated that the HHT/VEN combination concurrently downregulated key anti-apoptotic proteins, i.e., MCL1, leading to enhanced apoptosis. Importantly, the clinical results were very promising. Six patients with ETP-ALL with either refractory/relapsed (R/R) or newly diagnosed disease were treated with an HHT/VEN-based regimen. All patients achieved complete remission (CR) after only one cycle of treatment. CONCLUSIONS: Our findings demonstrate that a combination of HHT/VEN is effective on ETP-ALL and represents the "backbone" of a promising and safe regimen for newly diagnosed and R/R patients with ETP-ALL. FUNDING: This work was funded by the National Cancer Institute, Gehr Family Foundation, George Hoag Family Foundation, National Natural Science Foundation of China, and Key Research and Development Program of Zhejiang Province of China.

RESUMO

BACKGROUND: The interleukin-1 receptor accessory protein (IL1RAP) is highly expressed on acute myeloid leukemia (AML) bulk blasts and leukemic stem cells (LSCs), but not on normal hematopoietic stem cells (HSCs), providing an opportunity to target and eliminate the disease, while sparing normal hematopoiesis. Herein, we report the activity of BIF002, a novel anti-IL1RAP/CD3 T cell engager (TCE) in AML. METHODS: Antibodies to IL1RAP were isolated from CD138+ B cells collected from the immunized mice by optoelectric positioning and single cell sequencing. Individual mouse monoclonal antibodies (mAbs) were produced and characterized, from which we generated BIF002, an anti-human IL1RAP/CD3 TCE using Fab arm exchange. Mutations in human IgG1 Fc were introduced to reduce FcγR binding. The antileukemic activity of BIF002 was characterized in vitro and in vivo using multiple cell lines and patient derived AML samples. RESULTS: IL1RAP was found to be highly expressed on most human AML cell lines and primary blasts, including CD34+ LSC-enriched subpopulation from patients with both de novo and relapsed/refractory (R/R) leukemia, but not on normal HSCs. In co-culture of T cells from healthy donors and IL1RAPhigh AML cell lines and primary blasts, BIF002 induced dose- and effector-to-target (E:T) ratio-dependent T cell activation and leukemic cell lysis at subnanomolar concentrations. BIF002 administered intravenously along with human T cells led to depletion of leukemic cells, and significantly prolonged survival of IL1RAPhigh MOLM13 or AML patient-derived xenografts with no off-target side effects, compared to controls. Of note, BiF002 effectively redirects T cells to eliminate LSCs, as evidenced by the absence of disease initiation in secondary recipients of bone marrow (BM) from BIF002+T cells-treated donors (median survival not reached; all survived > 200 days) compared with recipients of BM from vehicle- (median survival: 26 days; p = 0.0004) or isotype control antibody+T cells-treated donors (26 days; p = 0.0002). CONCLUSIONS: The novel anti-IL1RAP/CD3 TCE, BIF002, eradicates LSCs and significantly prolongs survival of AML xenografts, representing a promising, novel treatment for AML.

RESUMO

OBJECTIVE: To examine characteristics of women with negotiated treatment plans, factors that contribute to newly forming a treatment plan, and the impact of plans on asthma management, and their satisfaction with care over 2 years. METHODS: Data came from telephone interviews with 324 women with asthma at baseline, 12 and 24 months. The effect of having a negotiated treatment plan on medication adherence, asking the physician questions about asthma, asthma management self-efficacy, and satisfaction with care was assessed over 24 months. Data were analyzed using mixed models. Analyses controlled for patient characteristics. RESULTS: Thirty-eight percent of participants reported having a negotiated treatment plan at three time points. Seeing an asthma specialist (χ(2)(1) = 24.07, p < .001), was associated with having a plan. Women who did not have a negotiated treatment plan at baseline, but acquired one at 12 or 24 months, were more likely to report greater urgent office visits for asthma (odds ratio (OR) = 1.37, 95% confidence interval (CI) = 1.07-1.61). No associations were observed between having a plan and urgent healthcare use or symptom frequency. When adjusting for household income, level of asthma control, and specialty of the caregiving provider, women who did not have a negotiated treatment plan (OR = 0.28, 95% CI = 0.09-0.79) and those with a plan at fewer than three time points (OR = 0.30, 95% CI = 0.11-0.83) were less likely to report medication adherence and satisfaction with their care (regression coefficient (standard error) = -0.65 (0.17), p < .001). No differences in asthma management self-efficacy or asking the doctor questions about asthma were observed. CONCLUSION: Women with asthma who had a negotiated treatment plan were more likely to see an asthma specialist. In the long-term, not having a treatment plan that is developed in partnership with a clinician may have an adverse impact on medication use and patient views of clinical services.

RESUMO

OBJECTIVE: To develop a clinical risk scoring system for identifying adolescents with dysglycemia (prediabetes or diabetes) who need further confirmatory testing and to determine whether the addition of non-fasting tests would improve the prediction of dysglycemia. STUDY DESIGN: A sample of 176 overweight and obese adolescents (10-17 years) had a history/physical exam, a 2-h oral glucose tolerance test, and non-fasting tests [hemoglobin A1c, 1-h glucose challenge test (GCT), and random glucose test] performed. Given the low number of children with diabetes, we created several risk scoring systems combining the clinical characteristics with non-fasting tests for identifying adolescents with dysglycemia and compared the test performance. RESULTS: Sixty percent of participants were white and 32% were black; 39.2% had prediabetes and 1.1% had diabetes. A basic model including demographics, body mass index percentile, family history of diabetes, and acanthosis nigricans had reasonable test performance [area under the curve (AUC), 0.75; 95% confidence interval (95% CI), 0.68-0.82]. The addition of random glucose (AUC, 0.81; 95% CI, 0.75-0.87) or 1-h GCT (AUC, 0.82; 95% CI, 0.75-0.88) to the basic model significantly improved the predictive capacity, but the addition of hemoglobin A1c did not (AUC, 0.76; 95% CI, 0.68-0.83). The clinical score thresholds to consider for the basic plus random glucose model are total score cutoffs of 60 or 65 (sensitivity 86% and 65% and specificity 60% and 78%, respectively) and for the basic plus 1-h GCT model are total score cutoffs of 50 or 55 (sensitivity 87% and 73% and specificity 59% and 76%, respectively). CONCLUSIONS: Pending a validation in additional populations, a risk score combining the clinical characteristics with non-fasting test results may be a useful tool for identifying children with dysglycemia in the primary care setting.

RESUMO

Health literacy has become a national priority in the United States. Although less is known about the rate, outcomes, and costs associated with health literacy globally relative to the United States, the subject has received increasing attention internationally as well. Definitions, conceptual models, and health literacy measures have proliferated in recent years, and consensus does not exist regarding which of these to use. This article offers the following 5 recommendations for setting a research agenda to advance the science of health literacy measurement: (a) develop a comprehensive unified conceptual framework, (b) leverage the measurement knowledge the field has gained thus far, (c) empirically test frameworks and measures using robust research methods, (d) use a tiered approach to measuring health literacy, and (e) advocate for ongoing research and dissemination. These recommendations seek to ensure clarity, rigor, and transparency as part of a systematic approach to health literacy measurement. Once these steps are taken, the field of health literacy can move forward more effectively.

RESUMO

PURPOSE: In 2007, University of Texas Health Science Center Houston School of Public Health at San Antonio (UTHealth SPH) and UT Health San Antonio Long School of Medicine (LSOM) designed and implemented a 4-year dual MD and Master of Public Health (MPH) program. Dual MD-MPH programs wherein students can receive both degrees within 4 years are unique, and programmatic evaluation may have generalizable implications for accredited MD-MPH programs. METHOD: Demographic information was collected from UTHealth SPH and LSOM student data. The primary outcome variable was MD-MPH program completion in 4 years. Comprehensive Basic Science Examination (CBSE) scores, United States Medical Licensing Examination Step 1 and Step 2 scores, and successful primary care residency match data were compared between MD-MPH and MD-only students. Family medicine, internal medicine, obstetrics-gynecology, and pediatrics were considered primary care residencies, and an analysis excluding obstetrics-gynecology was also conducted. RESULTS: Of 241 MD-MPH students enrolled 2007-2017, 66% were women, 22% Hispanic, and 10% African American. Four-year MD-MPH program completion occurred for 202 (93% of eligible) students; 9 (4.1%) received MD only, 3 (1.4%) received MPH only; and 4 (1.8%) received neither. MD-MPH students' median CBSE score was 2 points lower than for MD-only students (P = .035), but Step 1 and 2 scores did not differ. Primary care residency match was more likely compared with MD-only students, both including and excluding obstetrics-gynecology (odds ratio [OR]: 1.75; 95% confidence interval [CI]: 1.31, 2.33; and OR: 1.36; 95% CI: 1.02, 1.82, respectively). CONCLUSIONS: The 4-year MD-MPH program retains and graduates a socioeconomically and racial/ethnically diverse group of students with a 93% success rate. MD-MPH graduates were more likely to pursue primary care residency than non-dual-degree students, which may have implications for addressing population health disparities.

As part of a 5-year study to develop and validate an instrument for measuring success in long-standing community-based participatory research (CBPR) partnerships, we utilized the Delphi method with a panel of 16 community and academic CBPR experts to assess face and content validity of the instrument's broad concepts of success and measurement items. In addition to incorporating quantitative and qualitative feedback from two online surveys, we included a 2-day face-to-face meeting with the Expert Panel to invite open discussion and diversity of opinion in line with the CBPR principles framing and guiding the study. The face-to-face meeting allowed experts to review the survey data (with maintained anonymity), convey their perspectives, and offer interpretations that were untapped in the online surveys. Using a CBPR approach facilitated a synergistic process that moved above and beyond the consensus achieved in the initial Delphi rounds, to enhance the Delphi technique and the development of items in the instrument.

RESUMO

It is known that 8-chloro-adenosine (8-Cl-Ado) is a novel RNA-directed nucleoside analog that targets leukemic stem cells (LSCs). In a phase I clinical trial with 8-Cl-Ado in patients with refractory or relapsed (R/R) AML, we observed encouraging but short-lived clinical responses, likely due to intrinsic mechanisms of LSC resistance. LSC homeostasis depends on amino acid-driven and/or fatty acid oxidation (FAO)-driven oxidative phosphorylation (OXPHOS) for survival. We recently reported that 8-Cl-Ado and the BCL-2-selective inhibitor venetoclax (VEN) synergistically inhibit FAO and OXPHOS in LSCs, thereby suppressing acute myeloid leukemia (AML) growth in vitro and in vivo. Herein, we report that 8-Cl-Ado inhibits ribosomal RNA (rRNA) synthesis through the downregulation of transcription initiation factor TIF-IA that is associated with increasing levels of p53. Paradoxically, 8-Cl-Ado-induced p53 increased FAO and OXPHOS, thereby self-limiting the activity of 8-Cl-Ado on LSCs. Since VEN inhibits amino acid-driven OXPHOS, the addition of VEN significantly enhanced the activity of 8-Cl-Ado by counteracting the self-limiting effect of p53 on FAO and OXPHOS. Overall, our results indicate that VEN and 8-Cl-Ado can cooperate in targeting rRNA synthesis and OXPHOS and in decreasing the survival of the LSC-enriched cell population, suggesting the VEN/8-Cl-Ado regimen as a promising therapeutic approach for patients with R/R AML.

RESUMO

OBJECTIVES: We tested the effectiveness of a culturally tailored, behavioral theory-based community health worker intervention for improving glycemic control. METHODS: We used a randomized, 6-month delayed control group design among 164 African American and Latino adult participants recruited from 2 health systems in Detroit, Michigan. Our study was guided by the principles of community-based participatory research. Hemoglobin A1c (HbA1c) level was the primary outcome measure. Using an empowerment-based approach, community health workers provided participants with diabetes self-management education and regular home visits, and accompanied them to a clinic visit during the 6-month intervention period. RESULTS: Participants in the intervention group had a mean HbA1c value of 8.6% at baseline, which improved to a value of 7.8% at 6 months, for an adjusted change of -0.8 percentage points (P < .01). There was no change in mean HbA1c among the control group (8.5%). Intervention participants also had significantly greater improvements in self-reported diabetes understanding compared with the control group. CONCLUSIONS: This study contributes to the growing evidence for the effectiveness of community health workers and their role in multidisciplinary teams engaged in culturally appropriate health care delivery.

RESUMO

PURPOSE: School-based asthma interventions have been shown to be effective, but many may not be sensitive to the influence of peer interactions in shaping asthma-related emotional experiences. This exploratory study describes associations between peer interactions and asthma-related emotional experiences, asthma control, and outcomes among elementary-aged children with asthma. METHODS: Data come from the baseline assessment of a randomized trial evaluating the effect of a school-based asthma intervention. Univariate and multivariate statistics were completed to examine associations between peer interactions and asthma-related variables of interest. RESULTS: Eight hundred and thirty-five caregiver and child interviews were used in the analysis. Both males and females were enrolled in this study, 31% had not well controlled or poorly controlled asthma and 44% reported taking asthma medications. Overall, 26% of children talked to friends about asthma. Females were significantly more likely to talk to friends about asthma (p < .05) and more likely to report that they were worried, concerned, or troubled about asthma (p < .01). Significant differences in emotional quality of life between males and females were also found. Children who reported talking to friends about asthma were more likely to report teasing about asthma (OR = 2.47; 95% CI 1.57, 3.89) and to report that friends help with their asthma (OR = 1.79; 95% CI 1.07, 3.01). CONCLUSIONS: School-based asthma interventions should be sensitive to emotional-related outcomes associated with asthma and the influence of asthma-related peer interactions. Providing children with communication strategies for disclosure of asthma status to peers that result in more supportive interactions may be needed.

RESUMO

This study reviews obesity trends and physical education policies of 13 states with the highest and lowest youth obesity rates. A review of state policies for physical education was compared and analyzed. Although a majority of the states had physical education policies, they were typically not mandated and varied in time and grade-level requirements. However, little distinction in policies between states with higher and lower prevalence of obese youth was found. Financial and infrastructure support for the implementation and evaluation of physical education policies are needed, as well as innovative strategies including socioecological models to better address the obesity epidemic.
