Parental beliefs about medications and medication adherence among urban children with asthma.

BACKGROUND Although national guidelines recommend controller medications for children with persistent asthma, adherence is poor. Prior studies have begun to explore parental beliefs regarding controller asthma medications and their effect on adherence. OBJECTIVE To describe parental beliefs about controller medications among a community-based sample of urban children with persistent asthma and to examine the relationship between parental beliefs and adherence. DESIGN/METHODS Parents of 150 children with asthma completed a telephone survey as part of a larger asthma intervention. Parents of children using controller asthma medications were included in this study. A previously validated Beliefs About Medications Questionnaire (BMQ) was used, which included two subscales: necessity and concern. The relationship between parental beliefs about medications and medication adherence was assessed using bivariate linear regression and multivariate statistics. RESULTS This study included 67 children with parental report of controller medication (54% male, 61% African American, 69% Medicaid). Overall, 75% of parents strongly believed that their childs medications were necessary for their health and 34% had strong concerns about the medications. Only 22% of parents reported being completely adherent with medications. Parents with greater concern about medications were more likely to have poor adherence (P < .05). In a multivariate analysis, including both BMQ subscales and asthma severity, concern about medications significantly predicted poor medication adherence (P = .03). CONCLUSIONS Parental concerns about controller medications were associated with poor medication adherence for this population of urban children with asthma. These findings highlight the importance of addressing parental concerns at the time of medication prescription.

Randomized Controlled Trial to Improve Care for Urban Children With Asthma: Results of the School-Based Asthma Therapy Trial

OBJECTIVE To evaluate the impact of the School-Based Asthma Therapy trial on asthma symptoms among urban children with persistent asthma. DESIGN Randomized trial, with children stratified by smoke exposure in the home and randomized to a school-based care group or a usual care control group. SETTING Rochester, New York. PARTICIPANTS Children aged 3 to 10 years with persistent asthma. INTERVENTIONS Directly observed administration of daily preventive asthma medications by school nurses (with dose adjustments according to National Heart, Lung, and Blood Institute Expert Panel guidelines) and a home-based environmental tobacco smoke reduction program for smoke-exposed children, using motivational interviewing. MAIN OUTCOME MEASURE Mean number of symptom-free days per 2 weeks during the peak winter season (November-February), assessed by blinded interviews. RESULTS We enrolled 530 children (74% participation rate). During the peak winter season, children receiving preventive medications through school had significantly more symptom-free days compared with children in the control group (adjusted difference = 0.92 days per 2 weeks; 95% confidence interval, 0.50-1.33) and also had fewer nighttime symptoms, less rescue medication use, and fewer days with limited activity (all P < .01). Children in the treatment group also were less likely than those in the control group to have an exacerbation requiring treatment with prednisone (12% vs 18%, respectively; relative risk = 0.64; 95% confidence interval, 0.41-1.00). Stratified analyses showed positive intervention effects even for children with smoke exposure (n = 285; mean symptom-free days per 2 weeks: 11.6 for children in the treatment group vs 10.9 for those in the control group; difference = 0.96 days per 2 weeks; 95% confidence interval, 0.39-1.52). CONCLUSIONS The School-Based Asthma Therapy intervention significantly improved symptoms among urban children with persistent asthma. This program could serve as a model for improved asthma care in urban communities.

A randomized clinical trial of CPI-1189 for HIV-associated cognitive-motor impairment.

Background: CPI-1189 is a compound with antioxidant properties that blocks tumor necrosis factor-α (TNFα) effects in animal models. It has neuroprotective properties in model systems for HIV-associated neurotoxicity and thus is a candidate for neuroprotective therapy in humans with HIV-associated CNS disease. Objective: To assess the tolerability and safety of CPI-1189 in treating HIV-associated cognitive–motor impairment. Methods: Sixty-four subjects with mild to moderate HIV-associated cognitive–motor impairment were randomized to receive either placebo or 50 or 100 mg daily of CPI-1189 in addition to optimal HIV therapy. Subjects were followed prospectively in a double-masked study for 10 weeks. The primary assessment was tolerability and safety of the compound. Secondary objectives examined neuropsychological and functional change associated with this treatment. Results: The study compound was well tolerated, with 91% of CPI-1189-treated subjects and 76% of placebo-treated subjects completing the trial. Skin rash was seen equally in placebo and active arms, but the only study withdrawals due to skin rash occurred in CPI-1189-treated subjects (n = 2). One subject developed a cataract on drug (100 mg/day). CD4 lymphocyte counts and plasma HIV viral load remained stable in all groups throughout the trial. No significant treatment effects were observed on the change in composite Z-scores for eight neuropsychologic measures (NPZ-8). The Grooved Pegboard Test (nondominant) showed improved performance with CPI-1189 at 100 mg/day (p = 0.01), but no other neuropsychometric or functional measures demonstrated significant improvement. Conclusions: CPI-1189 was well tolerated in HIV subjects with cognitive–motor disorder. This study was not powered to conclusively determine efficacy and showed no consistent treatment-associated improvement in cognitive or functional measures.

Rasagiline improves quality of life in patients with early Parkinson's disease

The objective of this study was to determine the effects of rasagiline as monotherapy on quality of life (QOL) in patients with early Parkinsons disease (PD). Rasagiline, a potent, second‐generation, irreversible, selective monoamine oxidase B inhibitor improves PD symptoms in patients with early PD. Patients with early untreated PD were randomly assigned to once‐daily rasagiline 1 mg/day, rasagiline 2 mg/day, or placebo in a 6‐month, double‐blind trial (n = 404). At the end of 6 months, patients entered the preplanned, active‐treatment phase in which those receiving 1 mg/day and 2 mg/day of rasagiline continued on their previously assigned dosages and those receiving placebo switched to rasagiline 2 mg/day, while maintaining blinding to treatment assignments. QOL was measured with the Parkinsons Disease Quality of Life questionnaire (PDQUALIF) at 0, 14, 26, and 52 weeks after randomization. Analysis of the change in PDQUALIF scores from baseline to 6 months showed adjusted treatment effects (with 95% confidence interval) favoring rasagiline over placebo of −2.91 units (−5.19, −0.64, P = 0.01) for the 1 mg/day group and −2.74 units (−5.02, −0.45, P = 0.02) for the 2 mg/day. Subscore analysis attributed most of this benefit to the self‐image/sexuality domain. At 12 months (n = 266), with all groups receiving rasagiline for at least 6 months, no significant differences in PDQUALIF scores were seen between groups. Rasagiline improved QOL compared with placebo. This QOL improvement appears to be accounted for primarily by the symptomatic benefit of rasagiline.

Behavior Problems Among Inner-City Children With Asthma: Findings From a Community-Based Sample

OBJECTIVE. Previous studies have suggested a relationship between childhood asthma and behavior problems. However, few studies have used community-based samples to assess the prevalence of behavior problems among urban children with asthma symptoms. The objective of this study was to evaluate the relationship between asthma symptoms and behavior among a population-based sample of inner-city children and to determine the prevalence of behavioral comorbidity among children with asthma symptoms. METHODS. In 2003, parents of children who were entering kindergarten in the city of Rochester completed a detailed survey regarding the childs background, medical history (with specific questions about asthma symptoms), and behavior. We compared children with no asthma symptoms, intermittent symptoms, and persistent symptoms with regard to positive peer social skills (eg, makes friends easily), negative peer social skills (eg, fights with other children), task orientation (eg, concentrates well), and shy/anxious behavior (eg, is withdrawn) (validated scales; range: 1–4). We used multivariate regression to determine the independent association between symptom severity and behavioral outcomes. RESULTS. A total of 1619 children were included (response rate: 80%; mean age: 5.1 year), and 15% had asthma symptoms (8% persistent, 7% intermittent). Average negative peer scores were worse for children with persistent asthma symptoms compared with children with intermittent and no symptoms (mean scores: 1.88, 1.70, and 1.65). Children with persistent symptoms also scored worse than children with no symptoms on the assessment of task orientation (2.85 vs 3.03) and shy/anxious behavior (2.11 vs 1.89). Among children with persistent asthma symptoms, >20% scored >1 SD below average on 2 or more scales, compared with 16% of children with intermittent symptoms and 10% with no symptoms. CONCLUSIONS. Urban children with persistent asthma symptoms demonstrate more behavior problems across several domains compared with children with no symptoms. These findings suggest a clear need for an early biopsychosocial approach to care for vulnerable children with asthma.

The Role of Parent Health Literacy Among Urban Children with Persistent Asthma

UNLABELLED Health literacy (HL) affects adult asthma management, yet less is known about how parent HL affects child asthma care. OBJECTIVE To examine associations between parent HL and measures related to child asthma. METHODS Parents of 499 school-age urban children with persistent asthma in Rochester, New York completed home interviews. MEASURES the Rapid Estimate of Adult Literacy in Medicine (REALM) for parent HL; National Heart Lung and Blood Institute (NHLBI) criteria for asthma severity, and validated measures of asthma knowledge, beliefs, and experiences. ANALYSES bivariate and multivariate analyses of associations between parent HL measures related to child asthma. RESULTS Response rate: 72%, mean child age: 7.0 years. Thirty-two percent had a Hispanic parent; 88% had public insurance. Thirty-three percent had a parent with limited HL. Low parent HL was independently associated with greater parent worry, parent perception of greater asthma burden, and lower parent-reported quality of life. MEASURES of health care use (e.g., emergency care and preventive medicines) were not associated with parent HL. CONCLUSIONS Parents with limited HL worried more and perceived greater overall burden from the childs asthma, even though reported health care use did not vary. PRACTICE IMPLICATIONS Improved parent understanding and provider-parent communication about child asthma could reduce parent-perceived asthma burden, alleviate parent worry, and improve parent quality of life.

A Potential Pitfall in Provider Assessments of the Quality of Asthma Control

BACKGROUND Pediatricians elicit information about asthma control from parents to help formulate management plans. If parents of children with significant asthma symptoms inappropriately indicate good control, physician recommendations may not be optimal. We examined whether a single general question about asthma control might lead to inaccurate assessment of severity. DESIGN/METHODS Children 3-7 years of age who met the National Heart, Lung, and Blood Institute (NHLBI) criteria for mild persistent to severe asthma were identified from 40 urban schools. A phone survey of their parents provided demographic information, symptom frequency, medication use, and general interpretation of their childs asthma control. Chi-square analyses compared the parents general interpretation of control with demographic characteristics and measures of asthma severity. RESULTS One hundred sixty of 224 eligible children participated in this study. Seventy-eight percent were described as in good asthma control. General assessment of asthma control did not vary by demographic characteristics. Parents were as likely to describe children with daily asthma symptoms in good control as they were to describe children with less frequent symptoms in good control. Parents were less likely to report good control in children using daily rescue medications when compared with children with less frequent medication use (65% vs 82%, P =.03), but the majority of children in both groups was described as having good control. CONCLUSIONS Most parents underestimated the severity of their childs asthma and reported good control with their global assessment. Parents frequently reported good control even when the children had daily asthma symptoms. Pediatricians should ask about specific asthma symptoms during patient encounters because a global question about asthma control likely will result in underestimations of asthma severity.

Screening for Environmental Tobacco Smoke Exposure among Inner City Children with Asthma

OBJECTIVES. The goals were (1) to develop an index measure of environmental tobacco smoke based on parent self-report of smoking behaviors and (2) to determine whether the index score was associated with childrens present and future cotinine levels. METHODS. Data were drawn from a community intervention for inner-city children with persistent asthma (N = 226; response rate: 72%). Measures of child salivary cotinine levels and parent self-reported environmental tobacco smoke-related behaviors were obtained at baseline and 7 to 9 months later. To develop the index score, we used a 15-fold cross-validation method, with 70% of our data, that considered combinations of smoke exposure variables and controlled for demographic features. We chose the most parsimonious model that minimized the mean square predictive error. The resulting index score included primary caregiver smoking and home smoking ban status. We validated our model with the remaining 30% of the data. Analysis of variance and multivariate analyses were used to determine the association of the index score with childrens cotinine levels. RESULTS. Fifty-four percent of children with asthma lived with ≥1 smoker, and 51% of caregivers reported a complete home smoking ban. The childrens mean baseline cotinine level was 1.55 ng/mL (range: 0.0–21.3 ng/mL). Childrens baseline and follow-up cotinine levels increased as scores on the index measure increased. In a linear regression, the index score was significantly positively associated with childrens cotinine measurements at baseline and 7 to 9 months later. CONCLUSION. An index measure with combined information regarding primary caregiver smoking and household smoking restrictions helped to identify children with asthma with the greatest exposure to environmental tobacco smoke and could predict which children would have elevated cotinine levels 7 to 9 months later.

Underestimation of Children’s Weight Status: Views of Parents in an Urban Community

Objective. To examine the relationship between parents’ underestimation of their child’s weight status and concerns about their child’s weight and health. Methods. We conducted interviews with parents in an urban pediatric clinic (January through June 2006). Children’s height and weight were measured at the visit using standard techniques. Results. 193 children were included (response rate 87%, 18 months-9 years, 70% black); 31% of parents underestimated their child’s weight status (46% of overweight children, 24% of normal weight). Parents of normal-weight children who underestimated were more likely to be concerned about their child’s weight (39% vs 2.9%, P < .001) than those who did not underestimate. Parents of overweight children who underestimated were less likely to be concerned about their child’s weight (7.7% vs 59%, P < .001) than those who recognized their children as overweight. Conclusions. Many parents continue to underestimate their child’s weight status. These perceptions may present a barrier to the prevention of childhood obesity.

Environmental exposures and respiratory morbidity among very low birth weight infants at 1 year of life

Introduction: Preterm infants have a substantially increased risk of developing respiratory illnesses. The goal of this study was to consider the impact of modifiable postnatal exposures on respiratory morbidity among a cohort of very low birth weight (VLBW) infants. Objectives: (1) Assess the rates of respiratory morbidity and exposure to indoor respiratory triggers in a population of VLBW infants at 1 year; (2) determine the association between exposures and respiratory morbidity. Methods: We enrolled 124 VLBW infants into a prospective cohort study. Parents were called at 1 year to assess respiratory outcomes and environmental exposures. We used bivariate and multivariate analyses to assess the relationship between environmental exposures and acute care for respiratory illnesses. Results: At 1 year, 9% of infants had physician-diagnosed asthma, 47% required ⩾1 acute visit and 11% required hospitalisation for respiratory illness. The majority of infants (82%) were exposed to at least one indoor respiratory trigger. Infants living with a smoker (61% vs 40%) and infants exposed to pests (62% vs 39%) were more likely than unexposed infants to require acute care for respiratory problems. In a multivariate regression controlling for demographics, birth weight, bronchopulmonary dysplasia, and family history of asthma or allergies, both living with a smoker (OR 2.62; CI 1.09 to 6.29) and exposure to pests (OR 4.41; CI 1.22 to 15.94) were independently associated with the need for acute care for respiratory illnesses. Conclusions: In this sample, respiratory morbidity and exposure to triggers were common. VLBW infants may benefit from interventions that decrease exposure to respiratory triggers.
