It Costs The Government A Lot When You Just Sit

Spending large amounts of time sitting or lounging around during the day is linked to around 50,000 deaths per year in the United Kingdom.

In addition, the UK National Health Service (NHS) spends in excess of £0.7 billion (RM3.78bil) per year treating the health consequences.

This is suggested by research from Queen’s University Belfast and Ulster University, both in the UK, published online in the Journal of Epidemiology & Community Health.

A large proportion of the British population have sedentary jobs and leisure activities, and official physical activity recommendations regarding sedentary behaviour are vague.

Previous studies have shown that spending large parts of the day sitting down increases the risk of cardiovascular disease, type 2 diabetes, cancer and death, and is a burden on health services.

But no estimate of the financial impact that sedentary behaviour has on the UK NHS has been calculated, so the authors set out to do just that.

Figures calculated by other researchers on the impact sedentary behaviour has on the relative risks of five specific health conditions (type 2 diabetes, cardiovascular disease, colon cancer, endometrial cancer and lung cancer) and deaths from all causes, were combined with figures on the percentage of adults who are sedentary on any given day of the week, to estimate the overall impact sedentary behaviour has at a British population level.

Figures on sedentary behaviour were taken from the Health Survey for England 2012, which reported that 30% of adults in England spent at least six hours/day sedentary on weekdays, which increased to 37% on weekends.

Actual overall UK NHS spending on each of the five conditions, adjusted for inflation, was used to estimate the financial impact sedentary behaviour had on the UK NHS for each of the conditions in 2016-17.

For all five conditions combined, this amounted to £0.8bil (RM5.4bil).

As a proportion of patients will have more than one of the five conditions, e.g. around 30% of people with type 2 diabetes will also have cardiovascular disease, the researchers revised their figures to adjust for double-counting caused by comorbidity.

This reduced the overall cost of sedentary behaviour to £0.7bil (RM3.78bil).

Next, they took the figure calculated for the fraction of deaths from all causes that could be attributed to a sedentary lifestyle and multiplied it with the actual numbers of deaths that occurred in the UK in 2016.

The researchers say their results suggest that 11.6% of all deaths were associated with sedentary behaviour, and that 69,276 deaths might have been avoided in 2016 if sedentary behaviour was eliminated.

This is an observational study, and as such, can’t establish cause, and it also relied on estimates of people’s self-reported activity levels, which may not be accurate.

The study was also limited by the evidence available for the link between sedentary behaviour and health outcomes.

The authors point out that these costs are probably a conservative estimate of the true burden of sedentary behaviour because sedentary behaviour is likely to be associated with several other cancers, musculoskeletal disorders and mental health disorders, which are not included in their analysis.

Lead investigator Leonie Heron from the Centre of Public Health at Queen’s University Belfast, said: “Many individuals in the UK spend their leisure time in sedentary behaviour, and the workplace represents a significant proportion of unavoidable daily sitting time for many people.”

Measures should be taken to reduce sedentary behaviour with the aim of improving population health and reducing the financial burden to the health service, they conclude. – The BMJ
