    A study has found that middle-aged and older adults who live in greener neighborhoods have a decreased risk of developing metabolic syndrome (代谢综合征) such as obesity, hypertension (高血压) and high blood sugar.

The study, published in Environmental Pollution, was conducted by the Barcelona Institute for Global Health (ISGlobal). It differed from previous studies on the health benefits of green spaces in that it examined all of the symptoms of metabolic syndrome together collectively rather than as individual components. Having metabolic syndrome increases a person’s risk for heart disease, stroke and type 2 diabetes, according to the National Heart, Lung, and Blood Institute.

The study from ISGlobal examined data from clinical examinations of over 6,000 British adults who were between 45 and 69 years old when the study began. The data was derived from four examinations participants went through between 1997 and 2013 that included blood analyses, blood pressure and measurements of weight. “These findings suggest that long-term exposure to green spaces can play an important role in preventing metabolic syndrome as a whole,” according to a press release published by ISGlobal.

The correlation between nearness to green spaces and better health could be associated with the expanded opportunities for physical recreation and lower exposure to air pollution, according to Carmen de Keijzer, ISGlobal researcher and principal author of the study.

Female subjects were more likely than males to exhibit the study’s association between living in greener neighborhoods and having fewer metabolic symptoms. “Women tend to spend more time in their residential neighborhood, which could explain this gender difference,” de Keijzer said. “We need greener cities if we want healthier cities.” de Keijzer added.
