This book draws on the experience of an international group of paediatric epidemiologists, all of whom are world authorities in their field. In a consistent format they discuss biological considerations, patterns of occurrence, risk factors and the impact of interventions for each type of disorder. The disorders reviewed include not only the traditional morbidity of childhood such as infections, birth defects, asthma, and cerebral palsy, but also the new morbidity: emotional problems, intentional and non-intentional injuries, and suicide. This book will have wide appeal to health professionals at every level as it draws on personal experience combining paediatrics and epidemiology.
