ABSTRACT
OBJECTIVE: Pediatric and adult asthma account for increased healthcare utilization. Preventative measures such as ongoing adherence of preventative medications from childhood to adulthood are essential for positive outcomes. To identify potential challenges for optimal pediatric asthma care, we surveyed adult patients to reflect on their asthma management practices, and education and treatment barriers when they were a child. METHODS: A descriptive cross sectional survey of specific and open-ended questions in an urban academic medical center. Adult asthmatics (18-30 years old) who participated in a previous pediatric asthma study or received care from the adult emergency department (ED) were enrolled. RESULTS: Forty-one adult asthmatic patients (mean (S.D.) age 22.5 (3.5) years and 65.9% females) participated in the survey. Reported childhood asthma related experiences include never attended an asthma education session in almost two-thirds surveyed; their mother or grandmother as the primary person responsible for administering their medications (95.1%); inhaled short-acting beta-agonist (SABA) use information was not helpful (46.3%); wanted to learn more about allergic triggers (78%); and the need for additional asthma educational sessions (48.7%). CONCLUSION: All healthcare providers are encouraged to provide continuous asthma education to their pediatric patients and their family members or guardian.

BACKGROUND: Accurate symptom assessment remains challenging in teen populations. Little is known of usual symptom/response patterns, and self-reported paper diaries have traditionally low compliance rates. Therefore, we used concurrent digital voice diaries to capture daily asthma experiences. OBJECTIVE: (a) To qualitatively explore usual symptom patterns and self-management responses and (b) to quantitatively explore relationships between symptom severity and sentiment scores (a marker of emotional response to events). METHODS: Fourteen minority and nonminority teenagers (age 13-17) with controlled (50%) and uncontrolled asthma used digital recorders to report about their asthma once daily over 14 days. Dairy entries were coded for symptom frequency, severity, type, and self-management responses, while sentiment analysis was used to evaluate the emotional valence of diary entries and to explore whether increased symptom levels correlated with greater negative sentiment. RESULTS: Symptom frequency and severity recorded in voice diaries were much higher than teens indicated at baseline and were discordant with clinical assessments of asthma control. Of 175 entries, teens had symptoms 69.1% of days (121/175) and severe symptoms on one-third of these. Atypical symptoms (coughing, throat clearing) were reported twice as often as traditional symptoms (wheezing, chest tightness) and often not recognized as asthma, but rather attributed to being "sick" (25.6% of symptom days). Teens frequently minimized symptoms, used rescue and controller medication inconsistently, and resorted to alternative strategies to manage symptoms. Sentiment was not significantly correlated with assessed control (ß = 0.14, P = 0.28), but for teens reporting severe symptoms, sentiment scores decreased by 0.31 relative to teens without symptoms (P = 0.006). CONCLUSIONS AND CLINICAL RELEVANCE: Teens may minimize symptoms and have greater symptom frequency and severity than is recognized by themselves or providers. Screening for specific symptoms including coughing, throat clearing, and respiratory illness may be needed to identify those experiencing burden from asthma.

Objective: Urban children with asthma experience high rates of second hand smoke (SHS) exposure. The objective was to examine whether SHS exposure is associated with symptom frequency in children with poorly controlled asthma. Methods: Children were enrolled in a RCT to test the efficacy of an environmental control behavioral intervention versus an attention control group and followed over 12 months. SHS exposure assessed using salivary cotinine measurement. Frequency of child asthma symptoms, healthcare utilization, household smoking and caregiver daily life stress were obtained via caregiver report. Time of enrollment was recorded to assess seasonal factors. Symptom days and nights were the primary outcomes. Multivariable models and odds ratios examined factors that best predicted increased frequency of daytime/nighttime symptoms. Results: Children (n = 222) with a mean age of 6.3 (SD 2.7) years, were primarily male (65%), African American (94%), Medicaid insured (94%), and had poorly controlled asthma (54%). The final multivariable model indicated symptoms in the fall (OR 2.78; 95% CI 1.16, 6.52) and increased caregiver daily life stress (OR 1.13, 95% CI 1.02, 1.25) were significantly associated with increased symptom days when controlling for cotinine level, intervention status, child age and home and car smoking restrictions. Conclusions: There was no impact of SHS exposure on increased symptom frequency. High caregiver daily life stress and symptoms in fall season may place children with asthma at risk for increased day/nighttime symptoms. Close monitoring of symptoms and medication use during the fall season and intervening on caregiver life stress may decrease asthma morbidity in children with poorly controlled asthma.

OBJECTIVES: A previous definition of adolescent asthma self-management was derived from interviews with clinicians/researchers and published literature; however, it did not incorporate perspectives of teens or parents. Therefore, we conducted in-depth interviews with teens and parents and synthesized present findings with the prior analysis to develop a more encompassing definition and model. METHODS: Focal concepts were qualitatively extracted from 14-day self-management voice-diaries (n = 14) and 1-hour interviews (n = 42) with teens and parents (28 individuals) along with concepts found in the previous clinical/research oriented analysis. Conceptual structure and relationships were identified and key findings synthesized to develop a revised definition and model of adolescent asthma self-management. RESULTS: There were two primary self-management constructs: processes of self-management and tasks of self-management. Self-management was defined as the iterative process of assessing, deciding, and responding to specific situations in order to achieve personally important outcomes. Clinically relevant asthma self-management tasks included monitoring asthma, managing active issues through pharmacologic and non-pharmacologic strategies, preventing future issues, and communicating with others as needed. Self-management processes were reciprocally influenced by intrapersonal factors (both cognitive and physical), interpersonal factors (family, social and physical environments), and personally relevant asthma and non-asthma outcomes. CONCLUSION: This is the first definition of asthma self-management incorporating teen, parent, clinician, and researcher perspectives, which suggests that self-management processes and behaviors are influenced by individually variable personal and interpersonal factors, and are driven by personally important outcomes. Clinicians and researchers should investigate teens' symptom perceptions, medication beliefs, current approaches to symptom management, relevant outcomes, and personal priorities.

The goal of this longitudinal analysis was to characterize factors associated with the experience of life stress in low-income, inner-city mothers of minority children with high-risk asthma.Participants (n = 276) reported on family demographics, child asthma control and healthcare utilization, social support, contemporary life difficulties (housing, finances, violence exposure) measured by the validated Crisis in Family Systems scale, and daily stress. Latent growth curve modeling examined predictors of life stress across 12 months as a function of home and community difficulties, asthma-specific factors, and social support. Mothers were primarily single (73%), unemployed (55%), and living in extreme poverty with most (73%) reporting an annual family income <$20,000 (73%). The children were young (mean age = 5.59, SD = 2.17), African-American (96%), and had poorly controlled asthma (94%) at study enrollment. Higher daily stress was associated with financial difficulties, safety concerns in the home and community, and housing problems. Access to social support was consistently related to reduced stress. The only asthma-specific factor associated with life stress was healthcare utilization, with more emergency services for asthma related to higher daily stress. Findings underscore the clinical significance of assessing diverse home and community stressors and social support in low-income, inner-city caregivers of children with poorly controlled asthma.

BACKGROUND: Teens often have inadequate asthma self-management and control. However, little is known of their perceptions of or rationales for self-management behaviors. OBJECTIVES: To explore how teens self-manage asthma, including experiences, perceptions, responses to and reporting of symptoms. METHODS: A case-based, qualitative-descriptive design was used. Data were collected from minority and non-minority teens with controlled and uncontrolled asthma and their respective parents (N = 28). There were four data-collection points, including: (1) a primary teen interview; (2) parent interview; (3) 2-week self-management voice-diary; and (4) follow-up teen interview, incorporating symptom-response card-sorting to map symptoms and associated self-management responses. Seventy data sources were included in the analysis. RESULTS: Teens thought of their asthma symptoms as normal or unusual relative to their personal baseline symptom pattern; Those with uncontrolled asthma normalized higher levels of asthma symptoms than their counterparts with controlled asthma. Second, teens' decisions to treat symptoms of asthma with rescue medication were based on perceived benefits, burdens and accessibility of treatment balanced against perceived normalcy of symptoms. Teens with uncontrolled asthma had substantially higher treatment thresholds and delayed responses to symptoms compared to controlled peers. Third, teens never reported perceived normal symptoms of asthma to parents or providers, who were thus only aware of unusual or visible/audible symptoms. CONCLUSIONS: Teen's perceptions of symptoms and understanding of what is normal is the basis for self-management decisions. Improving self-management will likely entail modifying perceptions of symptoms and benefits/burdens of treatment to achieve healthier self-management patterns.

OBJECTIVE: Low-income caregivers of young children with high-risk asthma experience social stressors and illness-related demands that may impede effective home asthma management. Knowledge of the caregiving experience in the context of poverty is limited. METHODS: Convenience sampling methods were used to recruit low-income caregivers of children aged 7-12 years, who are frequently in the Emergency Room (ED) for uncontrolled asthma. Thirteen caregivers participated in focus groups that were designed to elicit reflections on asthma home and community management from the caregiver perspective. A grounded theory approach was used in the open coding of transcript data from three focus groups, as well as to revise and reorganize emerging themes and sub-themes. RESULTS: Participants (Mean age = 33.9 years) were predominantly the biological mother (92.3%), single (84.6%), and impoverished (69.2% reported annual household income ≤ $30,000). Their children (Mean age = 7.8 years) were African-American (100%), enrolled in Medicaid (92.3%), averaged 1.38 (SD = 0.7) ED visits over the prior 3 months, resided in homes with at least one smoker (61.5%), and nearly all (84.6%) experienced activity limitations due to asthma. Five themes emerged in the analysis: intensive caregiving role, complex and shared asthma management responsibility, parental beliefs and structural barriers to guideline-based care, lack of control over environmental triggers, and parent advocacy to improve child asthma care and outcomes. CONCLUSIONS: Caregivers managing a child with high-risk asthma in the context of poverty indicate the need for ongoing asthma education, increased sensitivity to the complexity of home asthma management, and family-centered interventions that enhance communication and collaboration between caregivers and providers.

Objectives Participation in the Special Supplemental Nutrition Program for Women, Infants, and Children (WIC) has been associated with lower breastfeeding initiation and duration. This study examines breastfeeding-related factors among WIC participants and nonparticipants that might explain these previous findings. Methods Respondents to the 2007 Infant Feeding Practices Study II who were income-eligible for WIC were categorized as follows: no WIC participation (No-WIC); prenatal participation and infant entry while ≥60 % breastfeeding (WIC BF-high); prenatal participation and infant entry while <60 % breastfeeding (WIC BF-low). Percent breastfeeding was the number of breast milk feeds divided by the total number of liquid feeds. Using propensity scores, we matched WIC BF-high respondents to No-WIC respondents on demographic and breastfeeding factors. We used logistic regression to estimate the impact of WIC participation on breastfeeding at 3 months postpartum in the matched sample. Within-WIC differences were explored. Results Of 743 income-eligible respondents, 293 never enrolled in WIC, 230 were categorized as WIC BF-high, and 220 as WIC BF-low. Compared to matched No-WIC respondents, WIC BF-high respondents had increased odds of breastfeeding at 3 months, though this difference was not statistically significant (OR 1.92; 95 % CI 0.95-3.67; p value 0.07). WIC BF-high respondents were more similar on breastfeeding-related characteristics to No-WIC respondents than to WIC BF-low respondents. Conclusions for Practice Accounting for prenatal breastfeeding intentions and attitudes, we find no negative association between WIC participation and breastfeeding at 3 months postpartum. This is in contrast to prior studies, and highlights the importance of understanding within-WIC differences.

BACKGROUND: One goal of guideline-based asthma therapy is minimal use of short-acting ß2 agonist (SABA) medications. Inner-city children with asthma are known to have high SABA use. OBJECTIVE: To examine factors associated with high SABA use in inner-city children with asthma. METHODS: One hundred inner-city children with persistent asthma were enrolled into a randomized controlled trial of an emergency department (ED) and home intervention. All children underwent serologic allergen specific IgE and salivary cotinine testing at the ED enrollment visit. Pharmacy records for the past 12 months were obtained. Number of SABA fills during the past 12 months was categorized into low- to moderate- vs high-use groups. SABA groups were compared by the number of symptom days and nights, allergen sensitization, and exposures. Regression models were used to predict high SABA use. RESULTS: Mean number of SABA fills over 12 months was 3.12. Unadjusted bivariate analysis showed that high SABA users were more than 5 times more likely to have an asthma hospitalization, almost 3 times more likely to have an asthma intensive care unit admission, and more than 3 times more likely to have prior specialty asthma care or positive cockroach sensitization than low to moderate SABA users. In the final regression model, for every additional inhaled corticosteroid fill, a child was 1.4 times more likely and a child with positive cockroach sensitization was almost 7 times more likely to have high SABA use when controlling for prior intensive care unit admission, receipt of specialty care, child age, and income. CONCLUSION: Providers should closely monitor SABA and controller medication use, allergen sensitization, and exposures in children with persistent asthma.

Previous research has found evidence of an association between indoor air pollution and asthma morbidity in children. Environmental intervention studies have been performed to examine the role of household environmental interventions in altering indoor air pollution concentrations and improving health. Previous environmental intervention studies have found only modest effects on health outcomes and it is unclear if the health benefits provided by environmental modification are comparable with those provided by medication. Traditionally, the statistical analysis of environmental intervention studies has involved performing two intention-to-treat analyses that separately estimate the effect of the environmental intervention on health and the effect of the environmental intervention on indoor air pollution concentrations. We propose a principal stratification approach to examine the extent to which an environmental intervention's effect on health outcomes coincides with its effect on indoor air pollution. We apply this approach to data from a randomized air cleaner intervention trial conducted in a population of asthmatic children living in Baltimore, Maryland, USA. We find that among children for whom the air cleaner reduced indoor particulate matter concentrations, the intervention resulted in a meaningful improvement of asthma symptoms with an effect generally larger than previous studies have shown. A key benefit of using principal stratification in environmental intervention studies is that it allows investigators to estimate causal effects of the intervention for sub-groups defined by changes in the indoor air pollution concentration.

OBJECTIVES: Rates of preventive asthma care after an asthma emergency department (ED) visit are low among inner-city children. The objective of this study was to test the efficacy of a clinician and caregiver feedback intervention (INT) on improving preventive asthma care following an asthma ED visit compared to an attention control group (CON). METHODS: Children with persistent asthma and recent asthma ED visits (N = 300) were enrolled and randomized into a feedback intervention or an attention control group and followed for 12 months. All children received nurse visits. Data were obtained from interviews, child salivary cotinine levels and pharmacy records. Standard t-test, chi-square and multiple logistic regression tests were used to test for differences between the groups for reporting greater than or equal to two primary care provider (PCP) preventive care visits for asthma over 12 months. RESULTS: Children were primarily male, young (3-5 years), African American and Medicaid insured. Mean ED visits over 12 months was high (2.29 visits). No difference by group was noted for attending two or more PCP visits/12 months or having an asthma action plan (AAP). Children having an AAP at baseline were almost twice as likely to attend two or more PCP visits over 12 months while controlling for asthma control, group status, child age and number of asthma ED visits. CONCLUSIONS: A clinician and caregiver feedback intervention was unsuccessful in increasing asthma preventive care compared to an attention control group. Further research is needed to develop interventions to effectively prevent morbidity in high risk inner-city children with frequent ED utilization.

BACKGROUND: Children with asthma receiving specialty care have been found to have improved asthma outcomes. However, these outcomes can be adversely affected by poor adherence with controller medications. OBJECTIVE: To analyze pharmacy fill patterns as a measure of primary adherence in a group of underserved minority children receiving allergy subspecialty care. METHODS: As part of a larger 18-month nebulizer use study in underserved children (ages 2-8 years) with persistent asthma, 53 children were recruited from an urban allergy practice. Pharmacy records were compared with prescribing records for all asthma medications. RESULTS: Allergist controller prescriptions were written in 30-day quantities with refills and short-acting ß-agonists (SABAs) with no refills. Only 49.1% of inhaled corticosteroid (ICS), 49.5% of combination ICS and long-acting ß-agonist, and 64.5% of leukotriene modifier (LTM) initial and refill prescriptions were ever filled during the 18-month period. A mean of 5.1 refills (range, 0-14) for SABAs were obtained during 18 months, although only 1.28 SABA prescriptions were prescribed by the allergist. Mean times between first asthma prescription and actual filling were 30 days (range, 0-177 days) for ICSs, 26.6 days (range, 0-156 days) for LTMs, and 16.8 days (range, 0-139 days) for SABAs. CONCLUSION: Underserved children with asthma receiving allergy subspecialty care suboptimally filled controller prescriptions, yet filled abundant rescue medications from other prescribers. Limiting albuterol prescriptions to one canister without additional refills may provide an opportunity to monitor fill rates of both rescue and controller medications and provide education to patients about appropriate use of medications to improve adherence.

BACKGROUND: Rates of preventive follow-up asthma care after an acute emergency department (ED) visit are low among inner-city children. We implemented a novel behavioral asthma intervention, Pediatric Asthma Alert (PAAL) intervention, to improve outpatient follow-up and preventive care for urban children with a recent ED visit for asthma. OBJECTIVE: The objective of this article is to describe the PAAL intervention and examine factors associated with intervention completers and noncompleters. METHODS: Children with persistent asthma and recurrent ED visits (N = 300) were enrolled in a randomized controlled trial of the PAAL intervention that included two home visits and a facilitated follow-up visit with the child's primary care provider (PCP). Children were categorized as intervention completers, that is, completed home and PCP visits compared with noncompleters, who completed at least one home visit but did not complete the PCP visit. Using chi-square test of independence, analysis of variance, and multiple logistic regression, the intervention completion status was examined by several sociodemographic, health, and caregiver psychological variables. RESULTS: Children were African-American (95%), Medicaid insured (91%), and young (aged 3-5 years, 56%). Overall, 71% of children randomized to the intervention successfully completed all home and PCP visits (completers). Factors significantly associated with completing the intervention included younger age (age 3-5 years: completers, 65.4%; noncompleters, 34.1%; p < .001) and having an asthma action plan in the home at baseline (completers: 40%; noncompleters: 21%; p = .02). In a logistic regression model, younger child age, having an asthma action plan, and lower caregiver daily asthma stress were significantly associated with successful completion of the intervention. CONCLUSIONS: The majority of caregivers of high-risk children with asthma were successfully engaged in this home and PCP-based intervention. Caregivers of older children with asthma and those with high stress may need additional support for program completion. Further, the lack of an asthma action plan may be a marker of preexisting barriers to preventive care.

Low-income mothers of children with uncontrolled asthma are an underserved population at risk for psychological distress. We examined the impact of violence exposure and child asthma morbidity on depressive symptoms in mothers of youths with uncontrolled asthma. Asthma symptoms and health care utilization, socio-demographics, and standardized measures of depressive symptoms and violence exposure were ascertained by self-report. Latent Growth Curve Modeling tested the associations of violence and asthma morbidity with depressive symptoms. Participating mothers (N=276) reported high baseline violence exposure (59.5%) and depressive symptoms (34.4%); nearly a quarter had clinically significant depressive symptoms at 12 months. Violence exposure was consistently associated with maternal depressive symptoms. Individual indicators of asthma morbidity were nonsignificant, but the cumulative effect of asthma morbidity was predictive of higher depressive symptoms. Findings suggest holistic risk assessment and interventions may be needed to ameliorate the chronic distress observed in mothers of youths with uncontrolled asthma.

OBJECTIVES: To examine the association of social and environmental factors with levels of second-hand smoke (SHS) exposure, as measured by salivary cotinine, in young inner-city children with asthma. METHODS: We used data drawn from a home-based behavioral intervention for young high-risk children with persistent asthma post-emergency department (ED) treatment (N = 198). SHS exposure was measured by salivary cotinine and caregiver reports. Caregiver demographic and psychological functioning, household smoking behavior, and asthma morbidity were compared with child cotinine concentrations. Chi-square and ANOVA tests and multivariate regression models were used to determine the association of cotinine concentrations with household smoking behavior and asthma morbidity. RESULTS: Over half (53%) of the children had cotinine levels compatible with SHS exposure and mean cotinine concentrations were high at 2.42 ng/ml (SD 3.2). The caregiver was the predominant smoker in the home (57%) and 63% reported a total home smoking ban. Preschool aged children and those with caregivers reporting depressive symptoms and high stress had higher cotinine concentrations than their counterparts. Among children living in a home with a total home smoking ban, younger children had significantly higher mean cotinine concentrations than older children (cotinine: 3-5 year olds, 2.24 ng/ml (SD 3.5); 6-10 year olds, 0.63 ng/ml (SD 1.0); p < .05). In multivariate models, the factors most strongly associated with high child cotinine concentrations were increased number of household smokers (ß = 0.24) and younger child age (3-5 years) (ß = 0.23; p < .001, R(2) = 0.35). CONCLUSION: Over half of the young inner-city children with asthma were exposed to SHS, and caregivers are the predominant household smokers. Younger children and children with depressed and stressed caregivers are at significant risk of smoke exposures, even when a household smoking ban is reported. Further advocacy for these high-risk children is needed to help caregivers quit and to mitigate smoke exposure.

The goal of the study was to examine the association between biomarkers and environmental measures of second hand smoke (SHS) with caregiver, i.e. parent or legal guardian, report of household smoking behavior and morbidity measures among children with asthma. Baseline data were drawn from a longitudinal intervention for 126 inner city children with asthma, residing with a smoker. Most children met criteria for moderate to severe persistent asthma (63%) versus mild intermittent (20%) or mild persistent (17%). Household smoking behavior and asthma morbidity were compared with child urine cotinine and indoor measures of air quality including fine particulate matter (PM(2.5)) and air nicotine (AN). Kruskal-Wallis, Wilcoxon rank-sum and Spearman rho correlation tests were used to determine the level of association between biomarkers of SHS exposure and household smoking behavior and asthma morbidity. Most children had uncontrolled asthma (62%). The primary household smoker was the child's caregiver (86/126, 68%) of which 66 (77%) were the child's mother. Significantly higher mean PM(2.5), AN and cotinine concentrations were detected in households where the caregiver was the smoker (caregiver smoker: PM(2.5) µg/m(3): 44.16, AN: 1.79 µg/m(3), cotinine: 27.39 ng/ml; caregiver non-smoker: PM(2.5): 28.88 µg/m(3), AN: 0.71 µg/m(3), cotinine:10.78 ng/ml, all P ≤ 0.01). Urine cotinine concentrations trended higher in children who reported 5 or more symptom days within the past 2 weeks (>5 days/past 2 weeks, cotinine: 28.1 ng/ml vs. <5 days/past 2 weeks, cotinine: 16.2 ng/ml; P = 0.08). However, environmental measures of SHS exposures were not associated with asthma symptoms. Urban children with persistent asthma, residing with a smoker are exposed to high levels of SHS predominantly from their primary caregiver. Because cotinine was more strongly associated with asthma symptoms than environmental measures of SHS exposure and is independent of the site of exposure, it remains the gold standard for SHS exposure assessment in children with asthma.

OBJECTIVE: To examine prospective relationships between caregiver's depressive symptoms and child asthma morbidity among inner-city African American families. METHODS: Phone surveys were conducted 6 months apart with 262 African American mothers of children with asthma. Cross-lagged structural path analysis was used for data analyses. RESULTS: Using goodness-of-fit indices, the final model for asthma symptoms had a good fit to the data. Time 1 (T1) maternal depressive symptoms predicted T2 child asthma symptoms (beta =.16, p <.01); however, T1 asthma symptoms did not predict T2 maternal depressive symptoms (beta =.03, non-significant). In contrast, in the final model for emergency department (ED) visits there was no predictive association between maternal depressive symptoms and ED visits. CONCLUSION: Maternal depressive symptoms may have a detrimental effect on child asthma morbidity among inner-city African American families, rather than vice versa. Ameliorating maternal depressive symptoms may result in better asthma outcomes for inner-city children.
