Findings suggest exposure to greenspace Is linked to lower risk of obesity-related cancer
A comprehensive study led by the University of Queensland has established a connection between regular exposure to greenspace and a decreased risk of obesity-related cancers. This pivotal research, spearheaded by PhD candidate Chinonso Odebeatu from the university’s School of Public Health, involved an extensive analysis of data pertaining to nearly 280,000 individuals, aged between 37 and 73, residing in England, Scotland, and Wales, who were recruited from 2006 to 2010.
“The large-scale biomedical database, Biobank UK, was utilised for the study, and we determined the greenspace around participants’ homes using the Ordnance Survey MasterMap Greenspace dataset,” explained Mr. Odebeatu. He further elaborated on the intent behind the study: “Our focus was on how greenspace might affect specific health outcomes, which led us to link the data to the UK’s National Cancer Registry.”
The findings were significant. Of the 279,000 participants, nearly 10,000 developed obesity-related cancers over an eight-year follow-up period. Mr. Odebeatu noted, “When we examined the type and quantity of greenspace around the participants, we discovered that exposure to a private residential garden was associated with a reduced risk of developing cancers, notably breast and uterine cancer.”
The study suggests that having greenspace nearby encourages physical activity, increases opportunities for Vitamin D synthesis, and might even mitigate the effects of air pollution. Mr. Odebeatu pointed out that the health benefits of access to a household garden were more pronounced among specific groups, including women, non-smokers, and individuals who abstain from alcohol.
“It was also more beneficial for individuals who were physically active, those without cardiovascular issues, and those not suffering from vitamin D deficiencies,” he added.
Associate Professor Nicholas Osborne, also from the University of Queensland’s School of Public Health, emphasised the broader implications of these findings. “These results support policies and initiatives that aim to increase people’s access to greenspace. We know living in areas with abundant greenspace can positively impact both physical and mental health and well-being,” Dr. Osborne stated.
He suggested that the study not only deepens understanding of the health benefits of greenspace but also underscores the importance of community gardens for those without access to private gardens. “Encouraging outdoor activities and ensuring adequate vitamin D levels could further amplify these benefits,” Dr. Osborne concluded.
This groundbreaking research was published in the journal Science of The Total Environment, highlighting the potential of greenspaces in combating obesity-related cancers and enhancing public health.
