Effect of peak flow monitoring on child asthma quality of life.

The purpose of this study was to evaluate the effect of peak flow monitoring on asthma quality of life (QOL) for school-age children with asthma (N = 77) who participated in a 16-week asthma self-management program. QOL was measured using the Children's Health Survey for Asthma. Findings indicated significant improvement in asthma QOL from baseline to Week 16 and higher QOL scores for those with better asthma health outcomes.

Icelandic and United States families of adolescents with asthma: predictors of health-related quality of life from the parents' perspective.

AIMS: To evaluate cultural differences in sociodemographic factors, illness severity and parents' perception of their adolescent's quality of life for Icelandic and USA families of adolescents with asthma; and to determine predictors of parent-rated quality of life. BACKGROUND: Asthma is known to have an impact on the quality of life of affected adolescents and their families, but few studies have addressed parents' perception of their adolescent's health-related quality of life. DESIGN: Cross-sectional exploratory study. METHOD: The study involved families of adolescents with asthma included 15 from Iceland and 15 from USA, recruited from paediatric practices. Parent and adolescent participants completed questionnaires; this study is based on the parent responses. Data were collected from January-May 2006. FINDINGS: While parents from Iceland and USA were similar in demographic characteristics, parents from Iceland rated their children's health-related quality of life (PedsQL(TM) 3.0, Varni 1998) more positively than did USA parents, even though Icelandic parents were more likely than their USA counterparts to report that their adolescent's asthma is severe. Significant predictors of parent-rated quality of life included location (higher scores for Icelandic parents), gender (higher scores for parents of boys), exposure to second hand smoke in the home (higher scores for those not exposed) and frequency of troublesome wheezing (higher scores for lower frequency). CONCLUSION: Quality of life has been acknowledged as an essential health outcome measure. Even though gender difference was not found in asthma severity, parents of boys perceived their adolescent's quality of life as more positive compared with parents of girls. It might be helpful for Icelandic and USA families to integrate into care delivery models, cultural differences in parent-rated quality of life. RELEVANCE TO CLINICAL PRACTICE: Asthma management interventions may improve quality of life for adolescents with asthma by reducing symptoms. Interventions promoting smoke-free homes and enhanced self-monitoring to prevent exacerbations may improve quality of life.

Adolescents with asthma: predictors of quality of life.

AIM: This paper is a report of a study to determine the demographic, personal, interpersonal and illness factors associated with asthma quality of life (QOL), as self-reported by adolescents from the United States of America (USA) and Iceland. BACKGROUND: Asthma affects 12% of children in the USA and an estimated 9% in Iceland. Limited research has addressed asthma QOL for adolescents. METHODS: This cross-sectional exploratory study included adolescents with asthma (n = 15 from the USA; n = 15 from Iceland), aged 13-17 years, primarily recruited from paediatric practices in central Kentucky, USA and Reykjavik, Iceland. Data were collected in 2006. Adolescents in the USA (47% male) had a mean age of 14.1 years (sd = 1.5); Icelandic adolescents (73% male) had a mean age of 15.1 years (sd = 1.4). Participants completed questionnaires measuring sociodemographic and asthma characteristics, degree of limitations due to asthma, self-rated health, depressive symptoms and asthma QOL. Multiple regression was used to determine predictors of asthma QOL. RESULTS: Gender was statistically significantly associated with QOL. The difference in QOL between adolescents in the USA and Iceland was not statistically significant. Statistically significant predictors of higher asthma QOL were a better rating of overall health (P < 0.01), not having had a severe asthma attack in the last 6 months (P < 0.01), and lower depressive symptoms (P < 0.05). CONCLUSION: Interventions designed to decrease depression and prevent asthma exacerbations may improve QOL for adolescents with asthma.

Testing an intervention to promote children's adherence to asthma self-management.

PURPOSE: To test the hypothesis that compared with the control group, 7 through 11-year-old children with persistent asthma who received asthma education plus a contingency management behavioral protocol would show higher adherence to peak expiratory flow (PEF) monitoring for asthma self-management and would report fewer asthma episodes. DESIGN AND METHODS: A randomized, controlled trial was conducted with 77 children with persistent asthma in a southeastern U.S. state. Both the intervention and control groups received instruction on PEF monitoring. Only the intervention group received asthma education plus contingency management, based on cognitive social learning theory, including self-monitoring, a contingency contract, tailoring, cueing, and reinforcement. At-home adherence to daily PEF monitoring during the 16-week study was assessed with the AccuTrax Personal Diary Spirometer, a computerized hand-held meter. Adherence was measured as a percentage of prescribed daily PEF uses at Weeks 4 (baseline), 8 (postintervention), and 16 (maintenance). RESULTS: At the end of the baseline period, the groups did not differ in adherence to daily PEF monitoring nor at Week 8. At Week 16, the intervention group's adherence for daily electronically monitored PEF was higher than that of the control group. Children in either group who were >or= 80% adherent to at least once-daily PEF monitoring during the last week of the maintenance period (weeks 8 to 16) were less likely to have an asthma episode during this period compared with those who were less adherent. CONCLUSIONS: The intervention to teach children to adhere to the recommended regimen for managing their asthma at home was effective.
