Workplace Risks For Asthma

A new study has found strong evidence for a link between cleaning jobs and risk of developing asthma.

Researchers at tracked the occurrence of asthma in a group of 9,488 people born in Britain in 1958. Not including those who had asthma as children, nine per cent developed asthma by age 42. Risks in the workplace were responsible for one in six cases of – even more than the one in nine cases attributed to smoking, according to the analysis.

There are many that are thought to cause asthma. In this study, 18 * were clearly linked with asthma risk, four of which were cleaning jobs and a further three of which were likely to involve exposure to cleaning products.

Farmers, hairdressers, and printing workers were also found to have increased risk, as previous studies have reported. Farmers were approximately four times more likely to develop asthma as an adult than office workers.

Besides cleaning products, flour, enzymes, metals, and textiles were among materials in the workplace identified in the study as being linked to asthma risk.

The study’s lead author, Dr Rebecca Ghosh of the MRC-HPA Centre for Environment and Health at Imperial College London, said: “This study identified 18 occupations that are clearly linked with asthma risk, but there are others that did not show up in our analysis, mainly because they are relatively uncommon. is widely under-recognised by employers, employees and healthcare professionals. Raising awareness that this is an almost entirely preventable disease would be a major step in reducing its incidence.”

The study, published in the journal Thorax, was funded by and the Colt Foundation.

Malayka Rahman, Research Analysis and Communications Officer at Asthma UK, said: “This research has highlighted a new group of people, specifically those working in occupations related to cleaning, such as cleaners or home-based personal care workers, who may have developed adult onset asthma due to exposure to chemicals they work with on a daily basis. We advise anyone who works in the industries highlighted in this study and who have experienced breathing problems to discuss this with their GP, and we urge healthcare professionals to make sure they consider possible occupational causes in adult onset asthma and tailor their advice to people with asthma accordingly.”

Around 5.4 million people in the UK have asthma, some of whom suffer as children and some of whom develop the disease in later life.


* The 18 occupations linked with asthma risk in the study were: cooks; waiters, waitresses and bartenders; home-based personal care workers; hairdressers, barbers and beauticians; protective service workers; market-oriented crop and animal producers; aircraft engine mechanics and fitters; compositors and typesetters; sewing-machine operators; cleaners unspecified; domestic helpers and cleaners; helpers and cleaners in offices and hotels; hand-launderers and pressers; messengers, package and luggage porters and deliverers; doorkeepers and watchpersons; building construction labourers; manufacturing labourers; hand packers and other manufacturing labourers.R.E.

People who have asthma caused by their work are eligible to make a claim for statutory Industrial Injuries Disablement Benefit from the Department for Work and Pensions. This scheme only covers employees and certain groups are not covered, for example, the self-employed, members of the armed services and some trainees. They may also take a civil claim for personal injury against their employer if they can demonstrate negligence.
