1.1 Wythenshawe Community Asthma Project (WYCAP)
Five surveys, each involving around 15,000 individuals, have been undertaken in two general practices in Wythenshawe over the past 12 years. Data collection for the most recent study was completed in February 2005. The surveys have studied:
• the prevalence of respiratory symptoms, obstructive airways disease and risk factors and temporal trends
• detecting airways disease using questionnaires
• health care utilisation and cost
• health related quality of life in subjects with and without respiratory symptoms and temporal changes in health related quality of life
WYCAP is a unique study showing the prevalence of respiratory symptoms, temporal changes over a 12 year period and health care utilisation in a population.
1.2 Health Related Quality of Life and Chronic illness using Wythenshawe Community Asthma Project (WYCAP)
Comparison of health related quality of life between different morbidities using a generic quality of life questionnaire (EQ-5D) in the WYCAP 2004 survey.
1.3 Manchester Community Asthma Study (MANCAS)
This study was funded by Asthma UK (formerly the National Asthma Campaign) and investigated the possible association between neonatal BCG vaccination and the subsequent development of asthma. The parents of approximately 2500 children responded to a questionnaire and were included in the study, and over 900 children had skin tests for allergies as part of the study.
This study examines the link between BCG vaccination and the development of atopic disease (asthma and allergies).
1.4 Manchester Community Asthma Study 2 (MANCAS2)
This study is funded by Moulton Charitable Foundation and is investigating the possible association and dose response between neonatal BCG vaccination and the subsequent development of asthma.
