Prevalence, risk factors and underdiagnosis of asthma in the general population aged over 60 years.

In the case of people living in the city centre, there was also higher asthma prevalence than in suburban and rural areas, but this difference in the elderly group did not reach statistical significance (OR = 1.59, 95% CI: 0.72–3.50, p > 0.05) due to the small size of the sample; however, it was significant in the younger age group (OR = 5.48, 95% CI: 2.88–10.43, p = 0.001).
