This study discusses childhood asthma as an increasing problem in Western culture. We present data from the PRAD [Psychosocial Risks for Allergy Development]-Project, which is a longitudinal study that has been running the last 14 years. When the subjects were 7-10 years old, the parents answered questionnaires about smoking, air pollution, behavior (via the Child Behavior Check List), and symptoms of allergy/asthma. Information about birth¬ weight was also gathered. In this study, the risk of developing asthma was as high in con¬ trols as it was in smoking families. IgE from umbilical blood had no predictive value for symptoms at the ages of seven-ten. As far as the risk for receiving an asthma diagnosis, we found statistically significant differences in birthweights for boys but not for girls. We dis¬ cuss the meaning of emotional climate, attitude, and "psychosomatic relationship" in rela¬ tion to this data. (Pediatr Asthma Allergy 1997;11[2]:95-102.)
