30% increased risk of dementia with shift work

Sleep is a healing process in the human body that restores the spirit and relieves fatigue
.
About one-third of a person's life is spent in sleep, good sleep is one of the three internationally recognized health standards, and too short sleep or poor sleep can affect health
.

In today's society, staying up late has become the new normal for many young people
.
Early studies have found that shift work increases the risk of metabolic disorders, cancer and cardiovascular disease, however, there is no consensus on whether shift work is associated with the onset of dementia
.

Recently, Professor Tang Yamei of Sun Yat-sen Memorial Hospital of Sun Yat-sen University published a research paper
entitled "Association of shift work with incident dementia: a community-based cohort study" in the journal "BMC Medicine".

The study showed a 30% increased risk of all-cause dementia in shift work compared to non-shift work, and that this relationship was not altered
by genetic predisposition.

In the study, researchers analysed 170722 healthy participants in the UK Biobank database with no cognitive impairment or dementia at baseline, self-reported shift work status, and analysed the relationship
between shift work and dementia risk.

During a mean follow-up period of 12.
4 years, a total of 716 cases
of dementia were recorded.

Data analysis found that shift work had a 30%
increased risk of all-cause dementia compared to non-shift work.

Relationship between shift work and dementia

In addition, multiple sensitivity analyses found that shift work and increased dementia risk did not change
due to genetic predisposition.

The researchers said the study has important public health implications, suggesting that occupational health management policies should be developed in the future to improve the long-term health and quality of life of
shift workers.
