Scientists from Columbia University (CU) found that people who do physically demanding jobs (sales, caregivers, farmers, animal breeders) may be more likely to develop dementia. The research was published in the journal Lancet Regional Health – Europe.
The authors analyzed data from 7,005 people aged 33 to 65, collected as part of HUNT4 70+, one of the world’s largest dementia studies. During the follow-up period, 92 participants were diagnosed with dementia and 2,407 participants were diagnosed with mild cognitive impairment.
It was revealed that those who work in jobs that require heavy physical labor between the ages of 33 and 65 have a 72% higher risk of developing dementia and mild cognitive impairment at the age of 70 than office workers.
The study’s authors classified the jobs of salespeople, cashiers, nurses, caregivers and farmers as physically demanding. All require frequent climbing, heavy lifting, standing, walking or bending.
The professions discussed are often associated with high stress and tight schedules. Additionally, such work may put a person at greater risk for hearing loss and exposure to hazardous substances that negatively impact cognitive function. The genetic and socioeconomic status of people who do heavy labor may also differ. Scientists suggest that people who do more physically demanding jobs may have lower mental abilities at an early age, which could affect their educational and employment opportunities.
The study highlighted the importance of developing strategies to prevent dementia among gig workers. But
The authors’ findings contradict another recent study. It showed the opposite: The risk of dementia increases in adults who spend more than 10 hours a day sitting.
