BACKGROUND: Environmental tobacco smoke (ETS) is a frequent exposure and is linked to asthma among inner-city children. OBJECTIVE: We sought to examine the relationship among ETS exposure, select asthma symptoms, and consequences among inner-city children with asthma. METHODS: Data from interviews with primary caregivers of inner-city elementary school children with asthma were evaluated (n = 590). Caregiver reports of child asthma symptoms, exercise limitations, asthma management, health care use, and ETS exposure were examined. RESULTS: Smoking in the home was reported by 29.4% of primary caregivers. ETS exposure (yes/no) was not related to frequency of child nocturnal symptoms or other select asthma morbidity markers. However, among children exposed to ETS, the frequency and severity of child nocturnal symptoms were highest among children exposed to moderate-to-heavy levels of ETS. After controlling for child age, anti-inflammatory medication use, asthma primary care, and caregiver's education, exposure to higher levels of ETS was associated with nearly a 3-fold increase in nocturnal symptoms in children (odds ratio, 2.83; 95% CI, 1.22-6.55). CONCLUSION: Among elementary school inner-city children with asthma, exposure to higher levels of ETS was associated with increased frequency of nocturnal symptoms. Reducing the exposure of children with asthma to ETS should be a clear priority in developing effective asthma management plans for inner-city families. 相似文献

Accurate perception of respiratory symptoms is highly important for course and treatment of asthma. Recent findings suggest that emotions can greatly impact respiratory symptom perception. This study compared the impact of emotions on respiratory symptom perception between patients with asthma and matched healthy controls. Pleasant and unpleasant emotional states were elicited by viewing emotional picture series while symptom reports and respiratory parameters were measured. Greater symptom report was observed for the unpleasant compared to the pleasant emotional state that was not related to respiratory parameters. Notably, this effect was comparable between patients with asthma and healthy controls. The present results suggest that the impact of emotions on respiratory symptom perception is a rather general phenomenon and not dependent upon previous experiences with asthma symptoms. 相似文献

Patterns of response to childhood asthma 总被引:2,自引:0,他引:2
The present study was designed to evaluate the concordance between parental and child ratings of asthma symptoms, and to determine the relationship between symptom ratings and morbidity data. The sample consisted of 162 asthmatic children from various treatment settings and 105 parents. The symptom pattern assessment employed a modified-for-children version of the Asthma Symptom Checklist (CASCL), which was completed independently by the parent and by the child. The CASCL data were factor analyzed to replicate the findings of the earlier panic/fear work. Factor analysis of both versions of the Asthma Symptom Checklist yielded three interpretable factors, which we labeled General Physical Symptoms, Panic/Fear, and Hyperventilation/Irritability. Correlations between parent and child across individual items ranged from 0.00 to 0.35. Correlations between the parents and the children across factor scores resulted in modest agreement. Using medication level, emergency room visits, and hospitalizations as indices of functional morbidity, many of the parents' and none of the children's factor scores were significantly related to functional morbidity. 相似文献

OBJECTIVE: To examine the relationships among maternal and child depressive symptoms and child and family psychosocial factors. METHOD: Secondary analysis of baseline data for a coping skills intervention for school-age children (ages 8-12) with type 1 diabetes (T1D) and their mothers. Children and mothers completed measures of depressive symptoms, coping, quality of life, and family functioning. RESULTS: There was a strong relationship between maternal and child depressive symptoms (r = .44, p < .001). Maternal depressive symptoms were negatively related to child quality of life, perceptions of coping, and family functioning. Impact of diabetes on quality of life, finding coping with diabetes upsetting, and family warmth mediated the relationship between maternal and child depressive symptoms. CONCLUSIONS: Maternal depression may negatively affect child adjustment through its influence on quality of life, coping, and family functioning. Implications for interventions to improve psychosocial adjustment in children with T1D are discussed. 相似文献

OBJECTIVES: (a) To assess emotional triggering of pediatric asthma and ascertain its contribution to disease morbidity and functional status; (b) to test whether negative family emotional climate (NFEQ) is associated with depressive and/or anxious symptoms and emotional triggering of asthma attacks in the child. METHOD: Children with asthma (N = 272, 56% male, age 7-17) and their primary caregivers answered together an Asthma Trigger Inventory (Ritz, Steptoe, Bobb, Harris, & Edwards, 2006). Children reported on anxious (STAIC) and depressive (CDI) symptoms and on asthma-related quality of life (PAQLQ). Parent(s) reported on their child's internalizing (CBCL-I) and depressive symptoms (CDI-P). A clinician also rated the child's depression using the structured CDRS-R. Asthma diagnosis was confirmed and disease severity rated according to NHLBI guidelines by an asthma clinician. RESULTS: Path analyses indicated that NFEQ was associated with depressive symptoms, which in turn were associated both directly and indirectly (by way of emotional triggering) with disease severity. Comparison of nested models indicated the possibility of differential roles and pathways for anxious versus depressive symptoms. CONCLUSION: Findings elucidate possible pathways of effect by which family emotional climate and child depressive symptoms may influence pediatric asthma disease severity by way of potentiating emotional triggering of asthma. 相似文献

BACKGROUND: The 1993 National Asthma Education Program Working Group on Asthma and Pregnancy defined asthma severity as mild, moderate, or severe on the basis of symptoms and spirometry, but no studies have evaluated the relationship between this classification system and subsequent asthma morbidity during pregnancy. OBJECTIVE: The objective of this study was to evaluate the relationship between asthma severity classification during pregnancy and gestational asthma exacerbations. METHODS: Asthma severity was defined according to the 1993 classification, adjusted to include medication requirements, in a volunteer sample of 1739 pregnant asthmatic patients who were less than 26 weeks' gestation. RESULTS: Initial asthma classification (mild, moderate, or severe) was significantly related to subsequent asthma morbidity during pregnancy (hospitalizations, unscheduled visits, corticosteroid requirements, and asthma symptoms during labor and delivery). Exacerbations during pregnancy occurred in 12.6% of patients initially classified as mild, 25.7% of patients classified as moderate, and 51.9% of patients classified as severe (P <.001). Asthma morbidity was similar, whether patients were classified as moderate or severe by symptoms and spirometry or by medication requirement. Thirty percent of initially mild patients were reclassified as moderate-severe during pregnancy, and 23% of the initially moderate-severe patients were reclassified as mild later in pregnancy; asthma morbidity in these patients changed accordingly. CONCLUSION: The National Asthma Education Program Working Group on Asthma and Pregnancy classification of asthma severity, adapted to include medication use, predicts subsequent asthma morbidity during pregnancy. 相似文献

BACKGROUND: A quarter of all consultations are for children, but there is little quantitative evidence documenting what parental factors are important in the decision to consult. AIM: To assess parental factors in higher child attendance (three or more times per year)--the 32% responsible for most (69%) general practice consultations with children. DESIGN OF STUDY: A random sample of 4000 individuals (one per household), including 670 children. SETTING: Six general practices within a 30-mile radius of the administrative centre. METHOD: Parents completed a postal questionnaire for themselves and their child. The adult questionnaire documented lifestyle, attitude to doctors and medicine, Kokko's personality types, perceived health, health anxiety, number of medical problems, medically unexplained somatic symptoms, and willingness to tolerate symptoms. The child questionnaire documented perceived health, the number of medical problems, somatic symptom inventory, willingness to tolerate symptoms, and self-reported attendance. RESULTS: (Adjusted odds ratios, test for trend, 95% confidence intervals.) A response rate of 490/670 (73%) paired adult and child questionnaires was obtained. Reported higher attendance was valid compared with the notes (likelihood ratio positive test = 5.2, negative test = 0.24), and was independently predicted by the child's age, medical problems, council house occupancy, and by the parents' assessment of the severity of the child's ill health. After controlling for these variables, higher attendance was more likely if the parents were higher attenders (adjusted OR = 3.71, 95% CI = 2.31-5.98), and if they perceived their children had medically unexplained physical symptoms (MUPS) (for 0, 1, 2, 3+ symptoms; adjusted ORs (95% CIs) = 1, 3.1 (1.7-5.7), 2.30 (0.97-5.5), 4.2 (1.8-9.6) respectively, P < or = 0.001). Attendance was less likely if they were willing to tolerate symptoms in their children (score for seven normally self-limiting scenarios = 0-17, 18-29 and 30+; adjusted ORs = 1, 0.71, 0.39 respectively, z for trend P = 0.03), willingness to tolerate symptoms and parental perception of child MUPS were associated with council house tenancy and health anxiety. Parents' perception of child MUPS also related to perception of child health and the parents' own MUPS. Parents of higher attenders were more likely to be depressed (HAD depression scale = 0-7, 8-10, 11+ respectively; adjusted ORs (95% CIs) = 1, 2.04 (1.27-3.27), 1.60 (0.75-3.42)) or anxious (anxiety scale 0-7, 8-10, 11+, respectively; adjusted ORs [95% CIs] = 1, 1.60 [0.99-2.58], 1.97 [1.20-3.26]). CONCLUSION: Important parental factors are council house tenancy, the parents' perception of and willingness to tolerate, somatic symptoms in the child, and the parents' own attendance history, health anxiety, and perception of somatic symptoms Doctors should be sensitive to the parental and family factors that underlie the decision to consult and of the needs of parents of high-attending children. 相似文献

BACKGROUND: Breathlessness in asthma often cannot be explained with objective variables indicating airways obstruction. The hypothesis that unrealistic breathlessness results from false interpretation of sensations was tested. METHODS: Sixty-four children and adolescents with asthma, aged 9-18 years, were randomly assigned to; (1) standardized physical exercise for induction of general symptoms; (2) equipment causing itching through skin irritation; or (3) physical exercise combined with equipment causing itching through skin irritation. Pre-test and post-test measures were: lung function; breathlessness; general symptoms; itching; state anxiety; and worry. RESULTS: Lung function decreased within normal parameters (3.8%, 1.1%, 2.6%, respectively) and did not differ significantly between conditions. Breathlessness increased significantly after exercise, particularly in condition 3. Breathlessness correlated with general symptoms and worrying, but not with changes in lung function, age, or asthma severity. CONCLUSION: Biased symptom perception can explain unrealistic breathlessness. Prerequisites are situational cues triggering selective perception and ambiguous sensations associated with the anticipated (feared) physical state. Excessive breathlessness may often warrant objective confirmation by means of lung-function testing. 相似文献

This study tested a novel extension of P. P. Schnurr and B. L. Green’s (2004) model of the relationships between trauma symptoms and health outcomes with specific application to HIV-positive men. A diverse sample of 167 HIV-positive men recruited from San Francisco Bay Area HIV clinics completed demographic, medical, trauma history, and symptom questionnaires. Mediation analyses were conducted using the method proposed by R. Baron and D. Kenny (1986). Regression analyses found that sexual revictimization (SR) significantly mediated the relationship between child sexual abuse and peritraumatic dissociation (PD), and PD mediated the relationship between SR and current posttraumatic stress (PTS) symptom severity. PTS symptoms partially mediated the relationship between SR and current HIV symptom severity. The findings indicate that among HIV-positive men, sexually revictimized men constitute a vulnerable group that is prone to PD, which places them at risk for posttraumatic stress disorder (PTSD) and worsened HIV-related health. Furthermore, traumatic stress symptoms were associated with worse HIV-related symptoms, suggesting that PTS symptoms mediate the link between trauma and health outcomes. This study highlights the need for future research to identify the biobehavioral mediators of the PTSD–health relationship in HIV-positive individuals. 相似文献

Add-on omalizumab improves day-to-day symptoms in inadequately controlled severe persistent allergic asthma 总被引:1,自引:1,他引:0
Background: Omalizumab is efficacious in the treatment of moderate-to-severe and severe persistent allergic (immunoglobulin E-mediated) asthma, reducing exacerbations, emergency visits and improving quality of life (QoL). However, as exacerbations are relatively infrequent, assessment of efficacy on day-to-day symptoms is warranted.
Aims: To investigate the effect of add-on omalizumab on day-to-day symptoms, and how they correlate with QoL in severe persistent asthma.
Methods: The correlation between asthma symptom scores and QoL [Asthma Quality of Life Questionnaire (AQLQ)] was assessed. Symptom-free days (total symptom score = 0) and symptom-controlled days (definition 1: total symptom score ≤1; and definition 2: morning peak expiratory flow ≥90% of baseline, daytime asthma score ≤1 and night-time asthma score = 0) were compared between the omalizumab-treated group, omalizumab responders and placebo.
Results: Four hundred and nineteen patients (omalizumab, n = 209; placebo, n = 210) were included in the efficacy analyses, and 61% (118/195) of patients with response data were classified as responders. Total symptom score strongly correlated with AQLQ overall and symptom scores and individual domains. AQLQ overall score correlated well with symptom scores. Responders had significantly more symptom-free days than the omalizumab-treated and placebo groups (45.8%, 37.2% and 22.6% respectively), and more symptom-controlled days (definition 1: 56.1%, 47.9% and 35.3%, respectively, and definition 2: 50.8%, 43.9% and 28.0%, respectively).
Conclusions: In patients with inadequately controlled severe persistent asthma, day-to-day symptoms correlate well with QoL. Add-on omalizumab significantly improves day-to-day symptoms compared with placebo. Further improvement in responders confirms the physician's assessment as a response measure. 相似文献

Inadequate symptom perception is increasingly recognized as a contributing factor in asthma morbidity. Recent research has shown that psychological factors can influence the perception of asthmatic symptoms such as dyspnea, but little is known, about the impact of emotions on the perception of dyspnea in pediatric asthma. Therefore, we examined the impact of viewing affective film clips of positive, neutral, and negative valence on perceived dyspnea during resistive load breathing in children with stable mild asthma. Perceived dyspnea decreased during the positive film compared to baseline and neutral film whereas the level of respiratory loading and respiratory resistance (R5) remained unchanged across conditions. The results underline the potential impact of psychological factors such as emotions on the perception of dyspnea in children with asthma. 相似文献

BACKGROUND: Nocturnal symptoms of asthma are a cause of significant morbidity and are included as a central feature in the categorization of asthma severity. OBJECTIVES: Data from the Childhood Asthma Management Program were used to estimate the prevalence of nocturnal awakenings in 1041 children with mild-to-moderate asthma and to investigate the relationships between awakenings and peak flows, severity of asthma, and allergen sensitivity and exposure. METHODS: Daily diary care data were recorded during a 28-day interval in the Childhood Asthma Management Program screening process. The data on morning and evening peak flows, overall symptom codes, albuterol use for symptoms, and nocturnal awakenings for asthma symptoms were analyzed and compared with measures of personal characteristics, pulmonary function, and environmental characteristics of the patients. RESULTS: Three hundred fifty-one (33.7%) children experienced 1 or more night awakenings caused by asthma during the 28-day screening period while not taking any maintenance medications. Greater risk of night awakening was associated with more severe asthma (greater responsiveness to bronchodilator, airway reactivity to methacholine, peak flow variability, and use of albuterol for symptoms, all P <.0001) and atopy (increased IgE and allergy skin test reactivity, both P =.0002). Those with a positive skin test response to dog and a high level of dog allergen in the home had a greater risk of night awakening caused by asthma (P =.01), as did those with a positive skin test response to cat and a high level of cat allergen in the home (P =.04). Mean daily symptom code and use of albuterol for asthma symptoms increased in the 3 days immediately before a single awakening compared with in the 4 to 6 days before the awakening (P =.02 and P =.01, respectively); however, both morning and evening peak flows as a percentage of personal best were similar in both intervals. Mean daily symptom code and daily use of albuterol were greater in the 3 days after an awakening than in the 3 days before (P <.0001 and P =.0002, respectively). Mean evening peak flow percentage of personal best the day after an episode of awakening was lower when a second consecutive awakening occurred than when there was only a single awakening (P =.01). CONCLUSIONS: Nocturnal awakening occurred in one third of the children with mild-to-moderate asthma during a month of relative stability and appears to be an indicator of asthma that is becoming increasingly severe. 相似文献

Inaccurate perception of respiratory symptoms is often found in asthma patients. Typically, patients who inaccurately perceive asthma symptoms are divided into underperceivers and overperceivers. In this paper we point out that this division is problematic. We argue that little evidence exists for a trait-like stability of under- and overperception and that accuracy of respiratory symptom perception is highly variable within persons and strongly influenced by contextual information. Particularly, expectancy and affective cues appear to have a powerful influence on symptom accuracy. Based on these findings and incorporating recent work on associative learning, attention and mental representations in anxiety and symptom perception, we propose a cognitive–affective model of symptom perception in asthma. The model can act as a framework to understand both normal perception as well as under- and overperception of asthma symptoms and can guide the development of affect-related interventions to improve perceptual accuracy, asthma control and quality of life in asthma patients. 相似文献

This study examined the relationship between obesity and asthma symptom perception in 200 youth with asthma. Repeated subjective and objective peak flow measurements were summarized using the Asthma Risk Grid (Klein et al., 2004), resulting in Accurate, Symptom Magnification and Danger Zone scores. Analyses were stratified by age and included ethnicity.For younger children, obesity was not significantly related to perception scores. For older children, a significant obesity-by-ethnicity interaction for Accurate Symptom Perception scores indicated that obese white children had lower accuracy than white nonobese children, while there was no difference for obese versus nonobese minority children. Obesity was also related to higher Symptom Magnification scores regardless of ethnicity for older children.These findings suggest that obesity may complicate asthma management by interfering with the ability to accurately perceive symptoms for some patients. More remains to be learned about the role of sociodemographic factors underlying this relationship. 相似文献

The influence of parent-child relatedness on depressive symptoms in children with asthma: tests of moderator and mediator models 总被引:2,自引:0,他引:2
OBJECTIVE: To examine the influence of parent-child relationship quality on the association between illness-related functional status and depressive symptoms in children with asthma. METHODS: Questionnaire data were collected from the child, caregiver, and physician. Fifty-five children with asthma (8-17 years of age), their caregivers, and physicians participated. RESULTS: Regression analyses suggest that patterns of mother-child relatedness (secure vs. insecure) mediate the relationship between functional status and depressive symptoms. CONCLUSIONS: The parent-child relationship may be an important pathway by which illness influences symptoms of depression in children with asthma. This study suggests that impaired functional status does not directly contribute to symptoms of depression, but rather influences the parent-child relationship in ways that may promote the development of depressive symptoms in the child. 相似文献

BACKGROUND: In 1998, the economic burden of asthma in the United States was estimated to be 12.7 billion dollars. Yet few studies have examined the relationship between the total costs of asthma-related care and measures of asthma morbidity. Understanding the relationship between total costs of asthma-related care and morbidity can assist in designing the most cost-effective asthma care strategies to improve patient outcomes and minimize total costs. OBJECTIVE: To investigate correlates of asthma costs for children with mild-to-moderate persistent asthma and, specifically, to characterize how closely the percentage of predicted forced expiratory volume in 1 second (FEV1) and symptom days were correlated with costs of illness. METHODS: A total of 638 parents and children with mild-to-moderate persistent asthma in 4 managed care delivery systems in 3 different US geographic regions were enrolled. Symptom burden and annual resource utilization were determined from reports of physician visits, hospitalizations, emergency department visits, medication use, and parental missed workdays. Spirometry was conducted on children who were 5 years and older. To characterize the relationship between symptom days and the percentage of predicted FEV1 with costs, we specified a multivariate regression model. RESULTS: The median total annual asthma-related cost for the group was 564 dollars (interquartile range [IQR], 131 dollars-1602 dollars). Indirect costs represented 54.6% of total costs. Medicines accounted for 52.6% of direct costs. The mean percentage of predicted FEV1 was 101.6% (range, 39.3%-183.5%; IQR, 91.6%-111.3%), with 91.4% of patients with a percentage of predicted FEV1 of more than 80%. Based on multivariate modeling, increasing asthma severity, use of peak expiratory flow rate meters, younger age, low-income status and nonwhite race, and longer duration of asthma were significantly associated with increasing cost. Symptom days (P < 0.001) predicted annual costs better than percentage of predicted FEV1 (P < 0.16) in this group of children. CONCLUSIONS: For the large number of children with mild-to-moderate persistent asthma and normal or near-normal lung function, symptom days are predictive of health care costs. For these insured children receiving care from 3 large managed care providers, low-income status and nonwhite race were the strongest correlates for increased asthma-related costs. 相似文献

BACKGROUND: Accurate symptom evaluation is a critical component of asthma management. Limited data are available about the accuracy of symptom evaluation by children with asthma and their parents, or the impact of various symptom-monitoring strategies on asthma morbidity outcomes. OBJECTIVE: The purpose of this randomized clinical trial was to evaluate the effect of three different intensities of symptom monitoring on asthma morbidity outcomes. METHODS: One hundred sixty-eight children (ages 6 to 19) of diverse racial, geographic, and socioeconomic backgrounds were randomized to 1 of 3 treatment groups (subjective symptom evaluation, symptom-time peak expiratory flow rate (PEFR) monitoring, daily PEFR monitoring) in this longitudinal, clinical trial. Outcome measures included a summary asthma severity score, forced expiratory volume in 1 second, symptom days, and health care utilization. RESULTS: Children who used PEFR meters (PFMs) when symptomatic had a lower asthma severity score, fewer symptom days, and less health care utilization than children in the other two treatment groups. Minority and poor children had the greatest amount of improvement using PFMs when symptomatic. Results were much less striking in white families. Thirty percent of families in the PFM treatment groups discontinued use entirely by 1 year postexit, whereas the majority of families who continued use (94%) used them only when symptomatic to inform symptom interpretation and management decisions. CONCLUSIONS: Not every child with asthma needs a PFM. Children and families facing extra challenges as a result of illness severity, sociodemographic, or health care system characteristics clearly benefited most from PFM use. 相似文献

BACKGROUND: Bronchial asthma is often complicated with allergic rhinitis (AR). OBJECTIVE: To investigate the relationship between the upper and lower airway diseases in children with asthma, we performed a questionnaire survey at 6 centers in Kinki area in Japan. METHODS: A questionnaire was filled out by parents of 333 asthmatic children (0-16 years, median age 7). It included questions concerning nasal symptoms, onset ages of rhinitis and asthma, correlation between nasal symptoms and asthma symptoms, and family history of allergic diseases. RESULTS: One hundred and fifty five (46.5%) subjects answered to have any nasal diseases; 20 with sinusitis, 46 with seasonal AR, and 119 (35.7%) with perennial AR. To further clarify the relationship of asthma and concomitant AR, we focused on patients with perennial AR and compared the clinical characteristics with patients with no nasal diseases. Percentage of non-atopic asthma was significantly lower in patients with comorbid AR than those without. Severity of asthma tended to be milder and family history of perennial AR was more often in the former than the latter group. Interestingly, asthmatic children with comorbid AR were more likely to have cold air-induced asthma exacerbations. In the subjects with comorbid AR, concomitant exacerbation of the upper and lower airways occurred in 38.7%. The median age of onset of asthma and nasal symptoms was 2 and 4 years, respectively. In 43.9% of them, upper airway symptoms started either before or simultaneously with asthma. CONCLUSION: The attention should be paid to the nasal symptoms in children with asthma, especially they have atopic asthma and positive family history of perennial allergic rhinitis. It is important that an appropriate diagnosis and treatment of nasal symptoms to better control asthma in children. 相似文献

BACKGROUND: Exposure to indoor allergens contributes to increased asthma morbidity. The Inner-City Asthma Study, a randomized trial involving home environmental allergen and irritant remediation among children aged 6 through 11 years with moderate-to-severe asthma, successfully reduced asthma symptoms. A cost-effectiveness analysis can help stakeholders to evaluate the potential costs and benefits of adopting such a program. OBJECTIVE: We sought to assess the cost-effectiveness of the environmental intervention of the Inner-City Asthma Study. METHODS: Incremental cost-effectiveness ratios for a 2-year study period were calculated. Health outcome was measured as symptom-free days. Resource use measures included ambulatory visits, hospitalizations, and pharmaceutical use. CIs were obtained by using bootstrapping. RESULTS: The intervention, which cost $1469 per family, led to statistically significant reductions in symptom days, unscheduled clinic visits, and use of beta-agonist inhalers. Over the year of the intervention and a year of follow-up, the intervention cost was $27.57 per additional symptom-free day (95% CI, $7.46-$67.42). Subgroup analysis showed that targeting the intervention to selected high-risk subgroups did not reduce the incremental cost-effectiveness ratio. CONCLUSIONS: A targeted home-based environmental intervention improved health and reduced service use in inner-city children with moderate-to-severe asthma. The intervention is cost-effective when the aim is to reduce asthma symptom days and the associated costs. 相似文献
