The ability to perceive accurately the onset and intensity of asthma symptoms is a cornerstone of effective asthma management. Research in pediatric and adult asthma patients has shown the important role of symptom perception in asthma management, morbidity, and mortality. Assessment of symptom perception ability has largely remained an empiric methodology(More)
OBJECTIVE To assess child adherence to preventive asthma medications; to investigate relations between knowledge, reasoning about asthma, and responsibility for management and adherence; and to determine the association between adherence and morbidity. METHODS Participants were 106 children with asthma and their parents. Medication adherence was(More)
OBJECTIVE To determine whether family response to asthma symptoms mediates the relationship between child symptom perception and morbidity. METHODS A total of 122 children with asthma, aged between 7 and 17 years (47% females; 25% ethnic minorities), were recruited from three sites. Participants completed a family asthma management interview and 5-6 weeks(More)
OBJECTIVE To determine whether a multi-dimensional cumulative risk index (CRI) is a stronger predictor of asthma morbidity in urban, school-aged children with asthma, than poverty or severity alone. METHODS A total of 163 children with asthma, ages 7-15 years (42% female; 69% ethnic minority) and their primary caregivers completed interview-based(More)
The purpose of this study was to examine the association between asthma symptom perception measured during a 5-6 week baseline and functional morbidity measured prospectively across a 1-year follow-up. Symptom perception was measured by comparing subjective ratings with peak expiratory flow rate (PEFR) and forced expiratory volume in one second (FEV(1)). We(More)
RATIONALE Disparities in pediatric asthma exist in that Latino children have higher prevalence and greater morbidity from asthma than non-Latino white children. The factors behind these disparities are poorly understood, but ethnic-related variations in children's ability to accurately recognize and report their pulmonary functioning may be a contributing(More)
BACKGROUND The lifetime prevalence of self-reported asthma among Puerto Ricans is very high, with increased asthma hospitalizations, emergency department visits, and mortality rates. Differences in asthma severity between the mainland and island, however, remain largely unknown. OBJECTIVE We sought to characterize differences in asthma severity and(More)
BACKGROUND Epidemiologic studies have documented higher rates of asthma prevalence and morbidity in minority children compared to non-Latino white (NLW) children. Few studies focus on the mechanisms involved in explaining this disparity, and fewer still on the methodological challenges involved in rigorous disparities research. OBJECTIVES AND METHODS This(More)
BACKGROUND Inaccurate symptom perception contributes to asthma morbidity and mortality in children and adults. Various methods have been used to quantify perceptual accuracy, including psychophysical (resistive loading) approaches, ratings of dyspnea during induced bronchoconstriction, and in vivo monitoring, but it is unclear whether the different methods(More)
BACKGROUND We examined the relationship between three different indicators of childhood asthma (asthma diagnosis, ever had an asthma attack, and asthma hospitalization) and having any psychiatric disorder, comorbid disorders, or specific disorders. Three study hypotheses were examined: 1) there will be subject variability in responses to the asthma(More)
