Asthma is associated with bullying victimization in rural adolescents.

OBJECTIVE: We characterized bullying among rural adolescents and examined the association between asthma and bullying victimization. METHODS: Participants (N = 1905; 44.5% Black) were students attending rural high schools who were screened for a randomized trial to address uncontrolled asthma. Screening questions asked students about asthma diagnosis and symptoms, bullying victimization, and demographic characteristics. Logistic regression analyses with school as a fixed effect were employed to examine the extent to which demographic factors, asthma diagnosis, asthma status (i.e. current asthma, no asthma, possible undiagnosed asthma), and among those with current asthma, asthma severity, were associated with bullying victimization. Sensitivity analyses using bullying frequency as the outcome were also conducted. RESULTS: 26.0% reported being bullied. Younger age and self-identifying as White were associated with increased risk of bullying victimization. Compared to those with no asthma, those with current asthma or possible undiagnosed asthma were at increased risk for bullying victimization (adjusted odds ratio [AOR] = 2.46; 95% confidence interval (CI) = 1.76-3.46 and AOR = 2.42; 95% CI = 1.87-3.14, respectively). Among those with current asthma, persistent symptoms increased the risk for bullying victimization (AOR = 2.59; 95% CI = 1.45-4.71). Similar results were obtained with sensitivity analyses. CONCLUSIONS: In a large rural community cohort, asthma was associated with bullying victimization. Findings suggest that rural students with asthma, with or without diagnosis, could benefit from schools creating inclusive environments that reduce victimization based on this medical condition. School administrators should foster environments that are accepting of all students' abilities and statuses, and healthcare providers can provide proper asthma management education to these adolescents.

Anxiety, depression and global distress among African American young adults with uncontrolled asthma.

BACKGROUND: Anxiety and depression are mental health disorders that are often comorbid with asthma. Urban African American young adults with asthma often experience increased risk of anxiety and depression. OBJECTIVE: To explore relationships between symptoms of psychological distress and asthma-related anxiety with asthma outcomes among urban African American young adults with poorly controlled persistent asthma. METHODS: A secondary analysis of baseline data from a larger study of 141 African American young adults with uncontrolled persistent asthma was examined. Participants completed the Brief Symptom Inventory (BSI-18), Youth Asthma-related Anxiety Scale, Asthma Control Test (ACT), a daily diary to assess asthma symptoms; and number of asthma attacks. Spirometry assessed airway obstruction. Generalized linear models tested associations. RESULTS: In multivariable models testing, higher somatization scores were significantly associated with lower ACT scores (adjusted ß = -0.49; 95% CI = -0.69, -0.28; p < 0.01), and higher symptoms (adjusted ß = 0.39; 95% CI = 0.14, 0.65; p < 0.01). After adding asthma-related anxiety to the model, the somatization subscale and asthma-related anxiety were significantly associated with ACT scores (adjusted ß = -0.36; 95% CI = -0.57, -0.15; p < 0.01), (adjusted ß = -0.32; 95% CI = -0.50, -0.14; p < 0.01), respectively. Asthma-related anxiety was also significantly associated with asthma attacks (adjusted ß = 0.24; 95% CI = 0.05, 0.43; p < 0.05). CONCLUSION: This study suggests, asthma-related anxiety may differ from general anxiety and be related to poorly controlled asthma among African American young adults.

Predictors of adherence to controller medication in urban African American emerging adults with uncontrolled persistent asthma.

BACKGROUND: African American emerging adults tend to have low adherence to asthma controller medication, as well as a disproportionate burden of asthma morbidity and mortality. This study explored constructs from the Information-Motivation-Behavioral Skills model as predictors of controller medication adherence in urban African Americans ages 18-29 (N=152) with uncontrolled asthma using multiple measures of self-reported adherence. METHODS: Structural equation modeling (SEM) was employed to test the hypothesized mediation model that specified the relationship among psychological distress, substance use, asthma knowledge, motivation, self-efficacy, and adherence. RESULTS: Results suggested that motivation is an important predictor of adherence to medication; moreover, higher self-efficacy was associated with higher motivation. Results also highlighted psychological distress as an important intervention target to improve medication adherence in emerging adults. CONCLUSIONS: The model tested in this study may offer a feasible framework for beginning to understand adherence to controller medication in this population.

Does Observed Conflict Recovery Play a Role in Adolescent Dating Aggression?

In a study of conflict recovery and adolescent dating aggression, 14- to 18-year-old couples (N = 209 dyads) participated in a 1-hr observational assessment. Negative behavior was observed during conflict-evoking "hot" tasks and in a "cooldown" task. Physical and psychological dating aggression were assessed via questionnaires. Negative behavior measured in the cooldown task was not associated with dating aggression after controlling for carryover effects of negativity from the hot to cooldown tasks. Moreover, cooldown negativity moderated the associations of hot task negativity and dating aggression. Actor and partner effects were disentangled via dyadic data analyses. Given the paucity of observational studies of dating aggression, our findings are an important contribution to the literature and in need of replication and extension.

Demand-avoid-withdraw processes in adolescent dating aggression.

We conducted an observational study of a collection of interactive processes known as "demand-withdraw" in relation to adolescent dating aggression. Couples (N = 209) aged 14-18 years participated in a challenging observational laboratory assessment to measure demands (i.e., pressures for a change), as well as demand → partner withdraw and demand → partner avoid sequences. Actor and partner effects were disentangled via dyadic data analyses. The results indicated a fairly consistent pattern in which demand → withdraw and demand → avoid sequences led by either partner were positively associated with both partners' physical and psychological aggression (measured via a dual informant questionnaire method). Further, higher quality demands (i.e., pressures for change that were specific and encouraged both members of the dyad to increase a given behavior) were inversely associated with aggression. Yet, all of the above associations were attenuated to the point of statistical nonsignificance after controlling for hostility. These results suggest two primary possibilities. The associations of demand → withdraw and demand → avoid sequences with dating aggression may be spurious, with the sequences merely markers for hostility, a known correlate of dating aggression. Alternatively, hostility may mediate the relations of demand → withdraw and demand → avoid sequences with dating aggression. Further research is required to test these competing explanations. Implications for preventive intervention are discussed.

Sleeping Healthy, Living Healthy: Using Iterative, Participatory Processes to Develop and Adapt an Integrated Sleep Hygiene/Mind-Body Integrative Health Intervention for Urban Adolescents.

Racial and ethnic minority adolescents living in urban settings experience sleep disparities. Few interventions have been developed to address these disparities. Guided by principles of participatory design and inclusion, our team developed a novel intervention that combined sleep hygiene education with mind-body integrative health (MBIH) practices to improve sleep quality among adolescents in New York City. The goal of this article is to describe our iterative development and design process, the final product, and future directions. Our participatory approach incorporated information from formative work with adolescents having lived experience, practitioners, and syntheses of published literature. The final intervention-Sleeping Healthy, Living Healthy-consists of six, 40-minute group sessions and one 20-minute individual session designed for high school students. Each session has a set of learning objectives, combining instruction, group activities, and discussions on sleep hygiene and MBIH topics. Our manualized intervention includes handouts created by a graphic design team that served as a review and reminder for home practice. We describe intervention implementation to two unique cohorts and detail our methods used to fine-tune the intervention between cohorts. Our partnership with and insights from both adolescents and practitioners serve as a guide for researchers aiming to use participatory methods to develop interventions to decrease health disparities in specific populations.

Group-Based Medical Mistrust in Adolescents With Poorly Controlled Asthma Living in Rural Areas.

Black youth and rural adolescents are two groups who experience asthma disparities. Racism and discrimination in health care likely lead to group-based (systems-level) medical mistrust for some adolescents. Group-based medical mistrust, one pathway by which racism drives health inequities, is associated with poorer outcomes for patients with chronic conditions. Despite its potential importance in adolescent asthma, previous research has not considered group-based medical mistrust in this population. To fill this gap, we characterize group-based medical mistrust among rural adolescents with poorly controlled asthma, examining demographic differences. We analyzed baseline data from a school-based clinical trial in which 164 adolescents (mean age = 16.3; 76.2% Black) completed the Group-Based Medical Mistrust Scale (GBMMS). Using linear regression, we tested associations with race, gender, and age, controlling for recent medical visits and insurance status. The total GBMMS mean score was 2.3 (SD = 1.22); subscale scores ranged from 2.3 to 2.4. Black adolescents reported significantly higher total GBMMS scores (ß = .45, p = .003) and significantly higher scores on two GBMMS subscales: suspicion of health care providers (ß = .56, p = .007) and lack of support from health care providers (ß = .36, p = .007). Gender and age were not associated with GBMMS scores. Health care providers need to consider medical mistrust and its role in their clinical care. Together with their institutions, health care providers and researchers should work toward changing systems that perpetuate racism to build trust as a means of reducing asthma disparities among adolescents.

Interpersonal- and Community-Level Risk Factors for Adolescent Obesity: An Examination of Sexual Identity, School Violence, and School Climate in a Large Sample of Urban Adolescents.

Sexual minority adolescents are more likely to have obesity compared to their heterosexual peers, but little is known about potential contributors to this disparity that lie outside of individual-level health behaviors, such as diet and exercise. One possible contributor is school violence victimization, a factor associated with overweight/obesity in adolescence. Another possible contributor is school climate, which is associated with feelings of safety and connectedness that can lower the likelihood of school violence victimization. Moreover, even less is known about relationships among all these factors among sexual minority adolescents. This gap in the literature was addressed by analyzing CDC's district-level data from the Youth Risk Behavior Survey and School Health Profiles (N = 60,625; 50.9% female, Mage = 16 years, 84.7% heterosexual, 15.3% sexual minority). Using multilevel mixed effects logistic regression models and controlling for covariates, it was found that among females and males, those with 2+ counts of last 12-month school violence victimization had higher odds of obesity than those with no school violence victimization (AOR = 1.33; AOR = 1.24). Furthermore, females and males in more positive LGBTQ school climates had lower odds of obesity than those in less positive school climates (AOR = 0.84; AOR = 0.85). There were no sexual identity differences in these models. Findings support the careful consideration of school violence victimization and LGBTQ school climate in future obesity prevention initiatives.

Asthma Knowledge, Self-Efficacy, and Self-Management Among Rural Adolescents with Poorly Controlled Asthma.

Rural adolescents with asthma are a disparate group. Self-management is essential to asthma control. We describe asthma knowledge, self-efficacy, and self-management behaviors among 198 rural adolescents with poorly controlled asthma, exploring demographic differences; we also test the application of Social Cognitive Theory to asthma self-management examining if self-efficacy mediates associations between knowledge and self-management. Asthma knowledge and self-management were relatively poor in our sample, particularly among male and White adolescents; greater knowledge was significantly associated with better symptom prevention and management. Self-efficacy partially mediated the association between knowledge and symptom prevention, but not acute symptom management, suggesting that knowledge may not improve symptom prevention behaviors without confidence to implement such behaviors and that factors beyond knowledge and self-efficacy likely play a role in asthma self-management in this population. Addressing asthma knowledge and self-efficacy could improve self-management and, ultimately, enhance asthma control among rural adolescents with poorly controlled asthma.

The Association of Mental Health, Asthma Control and Acute Care Visits Among Rural Adolescents with Poorly Controlled Asthma.

Anxiety and depressive symptoms are associated with asthma-related acute care utilization. Few studies include rural adolescents. Asthma control may be the mechanism by which mental health affects acute care. This study explored associations between generalized anxiety, asthma-related anxiety, depressive symptoms, and acute care visits, and tested if asthma control mediates these associations among 197 rural adolescents with asthma. Data analysis included descriptive statistics and regression. Controlling for age, sex and race/ethnicity, asthma-related anxiety was associated with higher odds of acute care visits (OR = 2.09, 95% CI [1.42, 3.07]). Asthma control mediated this relationship: one unit increase in anxiety, on average, increased the odds of having any acute care visit by 5%. Generalized anxiety and depressive symptoms were not associated with acute care visits. Helping adolescents reduce their concerns regarding asthma while improving their self-management skill may potentially to reduce acute care among rural adolescents.

Associations among anxiety, self-efficacy, and self-care in rural adolescents with poorly controlled asthma.

BACKGROUND: Rural adolescents are vulnerable to asthma; good self-care can reduce morbidity. The subtypes of anxiety (eg, asthma-related, generalized) may have differential associations with asthma self-care. Low self-efficacy, a determinant of behavior, is associated with increased anxiety. Little is known regarding these relationships in rural adolescents. OBJECTIVE: To evaluate whether anxiety symptoms are associated with asthma symptom prevention and management among rural adolescents and whether self-efficacy mediates these relationships. METHODS: We used baseline data from 197 rural adolescents (mean age = 16 years; 69% girls; 62% Black) who were part of a trial that tested the effectiveness of a school-based asthma intervention. Adolescents completed the Youth Asthma-Related Anxiety Scale, Screen for Child Anxiety and Emotional Disorders, Asthma Management Self-efficacy Index, and Asthma Prevention and Management Indices. Linear regression was performed to test whether: (1) asthma-related and generalized anxiety had curvilinear relationships with self-care; (2) social and separation anxiety had linear relationships with self-care; and (3) self-efficacy mediated relationships. RESULTS: Asthma-related anxiety had a significant curvilinear relationship with prevention (P = 0.001) and a linear association with management (P = .01). Generalized anxiety had a significant curvilinear association with management (P = .03), whereas social anxiety had a significant linear relationship with prevention (P = .04). Self-efficacy partially or fully mediated these relationships. CONCLUSION: Anxiety symptoms were associated with asthma self-care among this sample of rural adolescents, with differing roles for prevention and management. Self-efficacy may be a mechanism to improve asthma self-care among rural adolescents with anxiety. With a lack of self-efficacy, asthma-related, generalized, or social anxiety may motivate adolescents to take steps to care for their asthma.

Group-randomized trial of tailored brief shared decision-making to improve asthma control in urban black adults.

AIMS: To assess the intervention effects of BREATHE (BRief intervention to Evaluate Asthma THErapy), a novel brief shared decision-making intervention and evaluate feasibility and acceptability of intervention procedures. DESIGN: Group-randomized longitudinal pilot study. METHODS: In total, 80 adults with uncontrolled persistent asthma participated in a trial comparing BREATHE (N = 40) to a dose-matched attention control intervention (N = 40). BREATHE is a one-time shared decision-making intervention delivered by clinicians during routine office visits. Ten clinicians were randomized and trained on BREATHE or the control condition. Participants were followed monthly for 3 months post-intervention. Data were collected from December 2017 - May 2019 and included surveys, lung function tests, and interviews. RESULTS: Participants were Black/multiracial (100%) mostly female (83%) adults (mean age 45). BREATHE clinicians delivered BREATHE to all 40 participants with fidelity based on expert review of audiorecordings. While the control group reported improvements in asthma control at 1-month and 3-month follow-up, only BREATHE participants had better asthma control at each timepoint (ß = 0.77; standard error (SE)[0.17]; p ≤ 0.0001; ß = 0.71; SE[0.16]; p ≤ 0.0001; ß = 0.54; SE[0.15]; p = .0004), exceeding the minimally important difference. BREATHE participants also perceived greater shared decision-making occurred during the intervention visit (ß = 7.39; SE[3.51]; p = .03) and fewer symptoms at follow-up (e.g., fewer nights woken, less shortness of breath and less severity of symptoms) than the controls. Both groups reported improved adherence and fewer erroneous medication beliefs. CONCLUSION: BREATHE is a promising brief tailored intervention that can be integrated into office visits using clinicians as interventionists. Thus, BREATHE offers a pragmatic approach to improving asthma outcomes and shared decision-making in a health disparity population. IMPACT: The study addressed the important problem of uncontrolled asthma in a high-risk vulnerable population. Compared with the dose-matched attention control condition, participants receiving the novel brief tailored shared decision-making intervention had significant improvements in asthma outcomes and greater perceived engagement in shared decision-making. Brief interventions integrated into office visits and delivered by clinicians may offer a pragmatic approach to narrowing health disparity gaps. Future studies where other team members (e.g., office nurses, social workers) are trained in shared decision-making may address important implementation science challenges as it relates to adoption, maintenance, and dissemination.

The Impact of Positive School Climate on Suicidality and Mental Health Among LGBTQ Adolescents: A Systematic Review.

Lesbian, gay, bisexual, transgender, and queer/questioning (LGBTQ) adolescents are more likely to report suicidality and worse mental health than their heterosexual peers. We conducted a systematic review to examine the relationship between positive school climate and suicidality and mental health among LGBTQ adolescents. We searched the literature using PubMed, PsycINFO, and CINAHL. Six studies met inclusion criteria, and all had low to moderate risks of bias. Results indicate that LGBTQ students in schools with more positive school climates were at lower risk of suicidality and reported fewer depressive symptoms compared to students in less positive school climates. Being at the forefront of health in schools, school nurses have the opportunity to advocate for changes in school environments that promote positive mental health for all youth, including LGBTQ adolescents.

Professional development outcomes associated with interdisciplinary research: An integrative review.

BACKGROUND: Interdisciplinary research among health care professionals has gained importance over the last 20 years, but little is known about its impact on career development. PURPOSE: This study examined professional development outcomes associated with interdisciplinary research. METHODS: An integrative review was conducted using Whittmore and Knafl's framework. PubMed, Embase, PsycInfo, Web of Science, and CINAHL were searched to identify studies. FINDINGS: Thirteen studies were included. The majority used bibliometric analyses, finding that moderate level of interdisciplinary collaboration was associated with a greater amount and higher quality of publications. Interdisciplinary publications allocated more credit (i.e., had more authors). Interdisciplinary research proposals had less funding success than single discipline proposals. Important cultural and personal aspects of interdisciplinary research (e.g., work and communication styles, research goals) have not been assessed to date. DISCUSSION: Rigorous qualitative studies are needed to characterize benefits and challenges of interdisciplinary research to scholars and to institutions.

Individual and Neighborhood Factors Associated with Undiagnosed Asthma in a Large Cohort of Urban Adolescents.

Undiagnosed asthma adds to the burden of asthma and is an especially significant public health concern among urban adolescents. While much is known about individual-level demographic and neighborhood-level factors that characterize those with diagnosed asthma, limited data exist regarding these factors and undiagnosed asthma. This observational study evaluated associations between undiagnosed asthma and individual and neighborhood factors among a large cohort of urban adolescents. We analyzed data from 10,295 New York City adolescents who reported on asthma symptoms and diagnosis; a subset (n = 6220) provided addresses that we were able to geocode into US Census tracts. Multivariable regression models estimated associations between undiagnosed asthma status and individual-level variables. Hierarchical linear modeling estimated associations between undiagnosed asthma status and neighborhood-level variables. Undiagnosed asthma prevalence was 20.2%. Females had higher odds of being undiagnosed (adjusted odds ratio (AOR) = 1.25; 95% confidence interval (CI) = 1.13-1.37). Compared to White, non-Hispanic adolescents, Asian-Americans had higher risk of being undiagnosed (AOR = 1.41; 95% CI = 1.01-1.95); Latinos (AOR = 0.67; 95% CI = 0.45-0.83); and African-Americans/Blacks (AOR = 0.66; 95% CI = 0.52-0.87) had lower risk; Latinos and African-Americans/Blacks did not differ significantly. Living in a neighborhood with a lower concentration of Latinos relative to White non-Latinos was associated with lower risk of being undiagnosed (AOR = 0.66; CI = 0.43-0.95). Living in a neighborhood with health care provider shortages was associated with lower risk of being undiagnosed (AOR = 0.80; 95% CI =0.69-0.93). Public health campaigns to educate adolescents and their caregivers about undiagnosed asthma, as well as education for health care providers to screen adolescent patients for asthma, are warranted.

Does cross-cultural communication training for physicians improve pediatric asthma outcomes? A randomized trial.

OBJECTIVE: Adverse cross-cultural interactions are a persistent problem within medicine impacting minority patients' use of services and health outcomes. To test whether 1) enhancing the evidence-based Physician Asthma Care Education (PACE), a continuing medical education program, with cross cultural communication training (PACE Plus) would improve the asthma outcomes of African American and Latino/Hispanic children; and 2) whether PACE is effective in diverse groups of children. METHODS: A three-arm randomized control trial was used to compare PACE Plus, PACE, and usual care. Participants were primary care physicians (n = 112) and their African American or Latino/Hispanic pediatric patients with persistent asthma (n = 867). The primary outcome of interest included changes in emergency department visits for asthma overtime, measured at baseline, and 9 and 21 months following the intervention. Other outcomes included hospitalizations, asthma symptom experience, caregiver asthma-related quality of life, and patient-provider communication measures. RESULTS: Over the long term, PACE Plus physicians reported significant improvements in confidence and use of patient-centered communication and counseling techniques (p < 0.01) compared to PACE physicians. No other significant benefit in primary and secondary outcomes was observed in this trial. CONCLUSION: PACE Plus did not show significant benefit in asthma-specific clinical outcomes. More trials and multi-component strategies continue to be needed to address complex risk factors and reduce disparities in asthma care.

HABIT efficacy and sustainability trial, a multi-center randomized controlled trial to improve hydroxyurea adherence in youth with sickle cell disease: a study protocol.

BACKGROUND: Hydroxyurea (HU) is recommended as standard practice for youth with sickle cell disease (SCD). Yet, despite its efficacy, HU adherence in adolescents and young adults is often poor. Poor medication adherence increases disease burden, healthcare cost and widens health disparities. Adolescence is a critical time to improve adherence through improved chronic disease self-management. This study aims to test the efficacy of an intervention delivered to youth/parent dyads by community health workers (CHWs), augmented by tailored text messages on HU adherence (primary outcome). Secondary outcomes are intervention sustainability, youth health-related quality of life, self-management responsibility concordance, acute hospital use and self-reported disease symptoms. METHODS: Hydroxyurea Adherence for Personal Best in Sickle Cell Disease, "HABIT," is a 12 month multi-center randomized controlled trial. One hundred four youth, 10 to 18 years of age prescribed HU who meet eligibility criteria, enrolled with their parent as dyads, will be randomized 1:1 to either the HABIT intervention or to usual clinical care plus education handouts. All subjects will complete clinic visits at months 0, 2, 4, 6 (efficacy component), 9 and 12 (sustainability component) for assessment of HbF biomarker, other hematologic parameters, and to complete questionnaires. In addition, dyads assigned to the HABIT intervention will work with CHWs to identify a daily habit (e.g., brushing teeth) on which to build a HU adherence habit. Tailored daily text message reminders to support the habit will be developed by the dyad in collaboration with the CHWs and sent to parent and youth. At the 6 month visit, the intervention will end and the sustainability portion of the trial will begin. All data analyses will be based on intention to treat with all randomized subjects included in the analyses. DISCUSSION: Prior retrospective studies demonstrate that a majority of adolescents are poorly adherent to HU. If efficacious, the HABIT intervention has the potential to improve the lives of youth with SCD. TRIAL REGISTRATION: Clinicaltrials.gov NCT03462511 .

Shared decision-making in the BREATHE asthma intervention trial: A research protocol.

AIM: To evaluate the preliminary effectiveness of the BRief Evaluation of Asthma THerapy intervention, a 7-min primary care provider-delivered shared decision-making protocol that uses motivational interviewing to address erroneous asthma disease and medication beliefs. DESIGN: A multi-centre masked two-arm group-randomized clinical trial. METHODS: This 2-year pilot study is funded (September 2016) by the National Institute of Nursing Research. Eight providers will be randomized to one of two arms: the active intervention (N = 4) or a dose-matched attention control (N = 4). Providers will deliver the intervention to which they were randomized to 10 Black adult patients with uncontrolled asthma (N = 80). Patients will be followed three months postintervention to test the preliminary intervention effects on asthma control (primary outcome) and on medication adherence, lung function, and asthma-related quality of life (secondary outcomes). DISCUSSION: This study will evaluate the preliminary impact of a novel shared decision-making intervention delivered in a real world setting to address erroneous disease and medication beliefs as a means of improving asthma control in Black adults. Results will inform a future, large-scale randomized trial with sufficient power to test the intervention's effectiveness. IMPACT: Shared decision-making is an evidence-based intervention with proven effectiveness when implemented in the context of labour- and time-intensive research protocols. Medication adherence is linked with the marked disparities evident in poor and minority adults with asthma. Addressing this requires a novel multifactorial approach as we have proposed. To ensure sustainability, shared decision-making interventions must be adapted to and integrated into real-world settings. TRIAL REGISTRATION: Registered at clincialtrials.gov as NCT03036267 and NCT03300752.

Asthma and subjective sleep disordered breathing in a large cohort of urban adolescents.

OBJECTIVE: Sleep disordered breathing (SDB) has not been well studied in urban adolescents with asthma in community settings. Nor has the association of SDB symptoms and asthma severity been studied. We characterized self-reported symptoms suggesting SDB and investigated the association of SDB symptoms, probable asthma, and asthma severity. METHODS: 9,565 adolescents from 21 inner-city high schools were screened for an asthma intervention study. Students reported on symptoms suggesting SDB using questions from the 2007 NHANES, if they were ever diagnosed with asthma, and on asthma symptoms. Using generalized linear mixed models with logit link with school as a random intercept and adjusting for age, gender, and race/ethnicity, we examined associations of SDB symptoms, and demographic characteristics, probable asthma, and asthma severity. RESULTS: 12% reported SDB symptoms. Older and bi-racial participants (compared to Caucasian) had higher odds of symptoms suggesting SDB (p <.001). Compared to those without probable asthma, adolescents with probable asthma had 2.63 greater odds of reporting SDB symptoms (p <.001). Among those with probable asthma, the odds of reporting SDB symptoms increased with asthma severity. When exploring daytime severity and severity due to night wakening separately, results were similar. All results remained significant when controlling for age, gender, and ethnicity. CONCLUSIONS: In a large urban community cohort of predominately ethnic minority adolescents, self-reported SDB symptoms were associated with probable asthma and increased asthma severity. This study highlights the importance of SDB as a modifiable co-morbidity of asthma.

Climate Change Effects on Respiratory Health: Implications for Nursing.

PURPOSE: Greenhouse gases are driving climate change. This article explores the adverse health effects of climate change on a particularly vulnerable population: children and adults with respiratory conditions. APPROACH: This review provides a general overview of the effects of increasing temperatures, extreme weather, desertification, and flooding on asthma, chronic obstructive lung disease, and respiratory infections. We offer suggestions for future research to better understand climate change hazards, policies to support prevention and mitigation efforts targeting climate change, and clinical actions to reduce individual risk. FINDINGS AND CONCLUSIONS: Climate change produces a number of changes to the natural and built environments that may potentially increase respiratory disease prevalence, morbidity, and mortality. Nurses might consider focusing their research efforts on reducing the effects of greenhouse gases and in directing policy to mitigate the harmful effects of climate change. Nurses can also continue to direct educational and clinical actions to reduce risks for all populations, but most importantly, for our most vulnerable groups. CLINICAL RELEVANCE: While advancements have been made in understanding the impact of climate change on respiratory health, nurses can play an important role in reducing the deleterious effects of climate change. This will require a multipronged approach of research, policy, and clinical action.
