Highlights:
  • Green spaces can make you look slim and trim
  • Women living near green spaces (parks and gardens) are less prone to obesity
  • Spend more time in natural outdoor environments to get rid of excess weight

Living near green spaces can help women lose weight naturally, reports a new study. The findings of the study are published in the International Journal of Hygiene and Environmental Health.
Living Near Green Spaces can Lower Obesity Risk in Women

Women who live less than 300 meters from green space may be at lower risk of excess weight or obesity. This is the main finding of a study led by the Barcelona Institute for Global Health (ISGlobal), a centre supported by "la Caixa".

Details of the Study

Using information from the MCC-Spain multi-case control study, the researchers analyzed data on 2,354 people from seven Spanish provinces (Asturias, Barcelona, Cantabria, Madrid, Murcia, Navarre and Valencia).

The study participants, who ranged in age from 20 to 85 years, answered survey questions about their residential history, lifestyle (physical activity, leisure time, etc.), weight and height.

In addition, hip and waist circumference was measured and blood or saliva samples were collected. To determine whether or not participants were overweight or obese, the researchers used two markers that are commonly used in epidemiologic studies: body mass index and waist-hip ratio.

Findings of the Study

The study found a strong association between overweight or obesity in women and lack of access to urban green spaces such as parks and gardens. However, no such association was found in men.

"We do not have a clear understanding of the biological determinants behind the observed gender differences," commented ISGlobal researcher Cristina O'Callaghan-Gordo, the lead author of the study. "There are probably social factors, such as differences in how men and women use green spaces, that explain this disparity."

Using the DNA samples collected from the participants' saliva and blood, the researchers analysed the role of genetics in this association. "We studied genetic polymorphisms that have been associated with obesity in previous research," commented O'Callaghan-Gordo.

"In general, we observed a more marked reduction in risk of obesity in people with a genetic predisposition to this condition. This finding points to the existence of gene-environment interactions that could either trigger or prevent excess weight gain."

Overweight and Obesity: Catalysts of Disease

According to the World Health Organization, in 2016 more than 1.9 billion adults were overweight. Of these, more than 650 million were obese--a preventable condition. "Excess weight is an important risk factor for various non-communicable diseases, including cardiovascular, kidney and liver disease, diabetes, various musculoskeletal disorders, and some types of cancer," commented study leader Manolis Kogevinas, a researcher in the Non-communicable Diseases and Environment programme at ISGlobal. "It is also associated with increased all-cause mortality."

Key Note of the Study

Natural outdoor environments, including green spaces within urban settings, promote health and well-being by increasing levels of physical activity, reducing exposure to noise and reducing psychological stress, which is an important driver of weight gain.

"This study highlights the important role played by green space in the risk of excess weight and obesity in Spanish women. Understanding the mechanisms that explain this association is crucial to plan effective and successful public health interventions," concluded Kogevinas.
