Change in β₂-agonist use after severe life events in adults with asthma: A population-based cohort study: Life events and bronchodilator usage among adults with asthma.

ABSTRACT:

Objective

This prospective, population-based cohort study of 1102 Finnish adults with asthma, examined whether exposure to stressful life events is associated with the intensity of usage of inhaled short-acting β₂-agonists.

Methods

Survey data was collected by two postal questionnaires. Baseline characteristics were obtained in 1998 and data on 19 specific stressful events (e.g. death of a child or spouse or divorce) within the six preceding months in 2003. Exposure to life events was indicated by a sum score weighted by mean severity of the events. Participants were linked to records of filled prescriptions for inhaled short-acting β₂-agonists from national registers from 2000 through 2006. The rates of purchases of short-acting β₂-agonists
