Factors associated with asthma in Albania.

Background: This study was undertaken to see whether asthma in Albania (where it is particularly uncommon) is associated with certain 'western' characteristics, and with dietary and lifestyle factors that affect its occurrence elsewhere.

Methods: A screening survey was conducted among 2653 persons aged 20-44 years. A more detailed enquiry was conducted among a random subsample plus all others whose response indicated possible asthma.
