[Population risk of bronchial asthma occurrence in Moscow].
Age-specific prevalence and incidence of bronchial asthma (BA) were estimated in a number of districts in Moscow. The average prevalence was measured as the current proportion of BA patients registered in district outpatient clinics of both the center and periphery of Moscow (2442 patients in total) among the entire population served by to these clinics. This proportion was found to be 0.5% for both men and women. Before 25 years of age, BA appeared to be commoner in males (0.57%, versus 0.3% in females); after 40 years of age, it was commoner in females (0.89%, versus 0.47% in males). The morbidity of the disease measured as the frequency of new cases of BA (diagnosed for the first time in the given patient) had two maximums for each gender: in females, between birth and nine years of age and at 45-54 years (0.39 and 0.45%, respectively) and in males, between birth and nine years and at 55-64 years (0.75 and 0.74%, respectively); and a minimum at 20-29 years of age (0.14 and 0.05% for females and males, respectively). The majority (80%) of adult BA patients were first diagnosed with BA in adulthood. The dynamics of BA incidence appeared to differ in males and females. The male incidence changed more drastically with age, while the incidence in adult females reached a maximum 10 years earlier than in adult males. The population risk of being registered for BA (accumulated morbidity) by the age of 15, 40, and 80 was 0.98, 1.35, and 2.97%, respectively, for males and 0.58, 0.95, and 2.13%, respectively, for females.(ABSTRACT TRUNCATED AT 250 WORDS)
