Single men are significantly less likely to participate in bowel screening tests compared to those who live with a partner, according to a new University of Stirling study.
The findings are among the first to emerge from a pioneering study, Healthy Ageing in Scotland (HAGIS), which has collated comprehensive data on the economic, health and social circumstances of over 1,000 Scots aged 50+ years.
This comprehensive study of aging is the first of its kind in Scotland and will join the Gateway to Global Aging platform, which influences and informs public policy worldwide by supporting international aging research.
As part of the study, participants were asked whether they had ever taken part in the Scottish Bowel Screening Program, which is credited with saving 150 lives a year.
Since 2009, Scots aged 50 and over have the option of taking the free test, which involves sending three samples of feces to a local NHS laboratory, every two years. Screening is proactively offered to people aged between 50 and 74, while those 75 and over can participate on request.
The study found 74.7 percent of those surveyed had ever taken part in the screening program but it varied significantly depending on living arrangements and gender. In the case of men living with a partner, 79.5 percent had taken the test, however, that figure fell to 57.6 percent for those who lived alone.
In women, 77.8 percent of those living with a partner had taken the test compared to 73.3 percent of those living alone.
Principal Investigator David Bell, Professor of Economics at Stirling Management School, said: "Our research indicates that men are significantly less likely to accept the offer of a free bowel screening test if they are living alone, compared to those who have a partner.
"We believe this could be attributed to the support that partners offer each other in terms of encouraging each other to take part in the test. Those living with a partner also have someone to discuss the screening process with, helping to allay concerns and fears."
The research found that the participation rate of the youngest age group (50-54) was 58.7 percent and that the rate increased with age. Of those aged 55 to 59, 67.5 percent had taken a test, followed by 60-64 (77%), 65-69 (81.9%), 70-74 (77.8%) and 75-79 (79.5%).
Uptake was also lower in deprived communities, the research found. However, there did not seem to be a disparity in the participation rate between those living in urban and rural areas. The team said this "was not surprising" given the screening was conducted by post.
Professor Bell added: "We believe our findings could help to inform and shape health policy to ensure future campaigns can be targeted at those who are less likely to participate, such as males living alone in deprived areas.
"Ultimately, if the participation rate can be increased, more lives will be saved."
Professor Bell, working with Research Fellow Dr Elaine Douglas, launched HAGIS in July 2015. The £500,000 pilot study, funded by the US-based National Institute on Aging and Nuffield Foundation, asked 1,000 participants about a range of topics that affect their wellbeing, including finances, health, relationships and activities.
The primary role of HAGIS is to provide an evidence base for interventions aimed at improving the circumstances of older Scots. Once it is incorporated into the Gateway to Global Aging, its data can be used by researchers in other countries who wish to compare the circumstances of Scots with their older people.
