The participants drew on medical, lifestyle, and employment information supplied between 2007 and 2010 by 286,825 participants in the UK Biobank. The study participants were aged between 37 and 72, and either in paid employment or self-employed. 83% worked regular office hours, while 17% worked shifts, around 51% included night shifts.
Shift patterns comprised: never or occasional night shifts; irregular or rotating night shifts; and permanent night shifts.
Some 14,238 (around 5%) of all the study participants had asthma; in 4783 (nearly 2%) symptoms were moderate to severe (based on their medications).
The study analyzed the effect of working office hours with shift work on asthma diagnosis, lung function, and asthma symptoms.

"Interestingly, chronotype does change with age, getting later through adolescence and then earlier as adults age, suggesting that older individuals might find it more difficult to adjust to night shift work than younger adults," they explain.
"There are no specific national clinical guidelines for how to manage asthma in shift workers," they highlight, but adapting shift work schedules to suit individual chronotype might be a worthwhile public health measure that is worth exploring further, they suggest.
