Poor respiratory health outcomes associated with high illness worry and alexithymia: Eleven-year prospective cohort study among the working-age population

This study examined the extent to which illness worry, alexithymia, and low sense of coherence predicted respiratory disease, respiratory symptoms, and lung function in 2310 people of working age (30–54 years) in Finland. In one part of the study, lung function testing was undertaken using a Vitalograph wedge bellows spirometer.
