Risk factors for persistent asthma in adolescents : a community based longitudinal birth cohortDeverell, Marie January 2007 (has links)
[Truncated abstract] Asthma is a chronic and complex disorder and despite our increase in the understanding of the genetics, pathology and mechanisms underlying asthma a gold standard definition of asthma does not exist. A criterion for recognising and diagnosing asthma in epidemiological studies is crucial in order to determine risk factors for disease. Prospective longitudinal birth cohort studies have increased our understanding of the natural history and risk factors for asthma, yet we are still not able to accurately predict which children will go on to have asthma as adults. It is during the transition from childhood to adolescence where factors underlying asthma change and the prevalence of asthma shifts between the sexes. There are inconsistencies regarding risk factors for the development and persistence of disease during this transitional period. Risk factors predicting the development and persistence of asthma and intermediate phenotypes (BHR, airway inflammation and atopy) may be influenced by gender and risk factors predicting disease may differ between childhood and adolescence. Aims 1. To identify risk factors for Asthma, BHR and Atopy at 14yrs of age. 2. To determine risk factors for persistence of asthma between 6 and 14 years. 3. To examine the influence of gender on risk factors during adolescence. Method The West Australian Pregnancy Cohort is a longitudinal birth cohort. The cohort initially consisted of 2868 live births with follow-ups at 1, 2, 3, 6, 8, 10 and 14 years of V age. ... Strong associations were seen with BHR and new diagnosis of wheeze and asthma in VI teenagers. Interestingly having either a cat or dog inside was protective for persistence of disease; in particular stronger associations were seen in teenage girls not in boys. During this transitional period the risk factors for asthma and intermediate phenotypes differ between the sexes. Different mechanisms are likely to be involved in determining asthma in boys and girls during adolescence and shed new light on the recognised switch in the gender balance in asthma prevalence from the male predominance in childhood to the female predominance in adult life. Our understanding of the natural course of disease from the prenatal period to adulthood and the identification of the various asthma phenotypes has the potential to change prognosis and planning of therapeutic strategies. Identifying those at high risk for persistence of disease in the early stages of life will allow therapeutic interventions to be more appropriately targeted.

Psychosocial stress and health-related outcomes in chronic childhood asthma : using a biopsychosocial approach to understand transactional relationships across childhood and adolescenceCesareo, Jacqueline M January 2007 (has links)
[Truncated abstract] Despite significant scientific advances in tracking the complex physiological mechanisms that drive the asthma disease process, worldwide trends in childhood asthma continue to rise. This research sought to describe the relationships between psychosocial stress, psychosocial resources, asthma severity, and health-related outcomes from the standpoints of biopsychosocial and developmental theory. The research consisted of three studies based on a prospective study involving 2573 children from a community-based birth cohort. The cohort has been under active follow-up from birth and this thesis draws on data obtained at the 1, 2, 6, 10 and 13 year follow-ups . . . The final study undertook to describe the mediating influence of specific supportive behaviours provided by family members and peers to adolescents with asthma. Ninety-nine adolescents participating in the 13 year follow-up of the community cohort study completed a semi-structured interview adapted from the Diabetes Social Support Interview (La Greca et al., 1995) to assess supportive behaviours and the KINDL (Ravens-Sieberer & Bullinger, 1998) to assess QOL. It was predicted that illness-specific support would mediate the relationship between family dysfunction and quality of life. Qualitative analyses identified parents as important sources of tangible support, peers as important sources of companionship and emotional support, and siblings bridging the two, by providing tangible, companionship and emotional support to the adolescent. Mediator analyses found that specific parent behaviours perceived as unsupportive by the adolescent mediated the relationship between family dysfunction and self-oriented quality of life. Clinical implications support the integration of medical and psychological expertise in the treatment of asthma. Future research directions are also discussed.

Adolescent Academic Adjustment during Chronic Illness: Online Training for Child Life SpecialistsKoussa, Michelle D 12 1900 (has links)
Frequent absences resulting from a chronic illness can disrupt adolescent school involvement, impacting academic achievement and psychosocial development as a result. This study explores whether certified child life specialists (CCLSs) could be a resource for parents as they address their adolescents' academic disruptions. Specifically, this study assesses an online training program designed to increase CCLSs' knowledge and self-efficacy as related to adolescents' academic adjustment following frequent absences. This knowledge and skill based training was designed as a three part module with sections including: academic considerations, psychosocial considerations, and availability of school resources in promoting successful adolescent academic adjustment. 62 CCLSs were recruited to participate and complete measures evaluating knowledge, in relation to content included in each module, and self-efficacy, involving communication with parents in regards to adolescent academic adjustment. T-tests were conducted to determine whether there were differences in reports of self-efficacy and knowledge following participation in the intervention between and within the treatment and control groups. Results indicate statistical significance for enhanced knowledge and self-efficacy for the treatment group at post-test. Therefore, the outcomes from this study support the effectiveness of brief online training in fostering knowledge and feelings of efficacy for CCLSs in a context not typically included in child life education or certification. As a result, findings from this study may be used to expand intervention programs in the clinical setting to provide more comprehensive psychosocial care to adolescents diagnosed with a chronic illness.
