Study Details
Prevention LevelSecondary
Study Year1997
Molecular Weight of AgentHMW
CategoryAnimal-derived antigens
AgentCow hair allergen
Outcome/DiagnosisOccupational asthma
Activity InterventionAvoidance of barn, cessation of cattle farming
Participation RateLimitation: no report of participation rate
Intervention EffectivenessAvoiding the barn was not a sufficient avoidance measure for subjects if partner continued cattle farming. Subjects who abandoned cattle farming (n=14) were exposed to significantly less cow hair allergen in living quarters than subjects who avoided the barn (n=12) (p<0.001), and subjects who took no avoidance measures (n=19) (p<0.0001). Subjects who ceased cattle farming or avoided the barn experienced a reduced degree of sensitization than subjects who took no avoidance measures (p<0.01). Reduced symptom score was also associated with abandonment of cattle farming in comparison to barn avoidance and no avoidance measures (p<0.05).
