The aim of this study was to assess the prevalence of asthma (self-reported) and relate this to lung function and factors associated with asthma in young farmers.
Two hundred and ten female and 1,691 male farming students together with 407 males controls were studied.
Each subject underwent a medical interview ; forced expiratory volume in one second (FEVI) and forced vital capacity (FVC) were recorded using a dry wedge spirometer.
Histamine bronchial reactivity was measured using the Yan method.
Skin prick testing was performed using inhalant allergens.
Nonsmokers had lower prevalence of asthma (5.4-10.8% .) than smokers (11.3-21.0%) (p<0.05).
Females reported symptoms of asthma nearly twice as often as males.
Sex, smoking and a family history of asthma/allergy were significantly associated with asthma.
Controls had higher standardized FEVI and FVC residuals than male students, both nonsmokers (0.21 and 0.24) versus (-0.06 and - 0.05) and smokers (0.29 and 0.33) versus (-0.11 and 0.13) (p<0.032).
Bronchial hyperresponsiveness, asthma, siblings with allergy and working with cattle (controls only) were significantly associated with reduced lung function.
In conclusion, the prevalence of asthma was significantly related to smoking, female sex, family history of asthma and allergy. (...)
