There is evidence that worrying about job security is a risk factor for poor health. During Europe's recent economic downturn, which started in 2008, studies show perceptions of job insecurity rose significantly. Now new research from Germany looking at this period links job insecurity with higher risk of developing asthma for the first time.

According to the World Health Organization, around 235 million people worldwide have asthma, a major noncommunicable disease whose symptoms include breathlessness and wheezing, and which vary in severity and frequency from person to person.

For their study, the team analyzed data collected in the German Socio-Economic Panel Study, which surveys a representative sample of the adult German working population every year.

The data they analyzed came from just over 7,000 working adults who completed the survey in 2009 and 2011, when questions about asthma were included. This is also the period of severe economic downturn across Europe, Medical News Today reminds.

The data showed that between 2009 and 2011, there were 105 cases of new-onset asthma among the respondents.

The researchers noted that the respondents who saw the likelihood of job loss over the next 2 years as high, tended to be younger, on lower incomes, with fewer years of education, and more likely to be single, compared to those who rated the likelihood of job loss as low or non-existent.

They also found the respondents who felt less secure about their jobs tended to exclude those on permanent contracts and were more likely to have been diagnosed with depression.

In a further analysis, after ruling out various factors like age, income, gender, depression and lifestyle, the team found the risk of developing asthma for the first time tended to rise in line with job insecurity.

They found every 25% increase in perceived likelihood of job loss was tied to a 24% increased risk of being diagnosed with new-onset asthma.

Those who thought they were very likely to lose their jobs in the next 2 years showed a 60% increased risk of developing first-time asthma, compared to those who rated the risk of job loss as low or non-existent.
