The influence of bronchial asthma on premenstrual syndrome prevalence among girls.

The aim of this study was to evaluate the effect of bronchial asthma and its severity on the prevalence of premenstrual syndrome (PMS) among girls. Eighty girls aged 12-19 years were qualified to the study as a research population (50 girls with bronchial asthma and 30 healthy girls). In research part, age at menarche, menstrual cycle parameters, and premenstrual symptoms were analyzed. The mean age in the asthma group was 15.24+/-1.62 years and that in the control group was 15.30+/-1.64 years. The mean duration of bronchial asthma was 6.66+/-4.73 years. The prevalence of PMS among girls with asthma (20%) was significantly lower compared with healthy girls (46.67%) (P=0.012). The intensity of PMS correlated with later age at menarche (P=0.01), lack of use oral contraceptives (P=0.03), and use of b-mimetics (P=0.017). In conclusion, bronchial asthma decreases the risk of PMS prevalence among girls.
