Moving to a Poor Neighborhood Can Cause Weight Gain
Where we live may influence how much we weigh even more than we once thought. It's long been known that a person's neighborhood can impact how much they weigh evidence suggests that socioeconomic environments influence a person's ability to adopt healthy behaviors. Now, a new study suggests that moving between neighborhoods can also cause changes in body weight. The research, published in the American Journal of Preventive Medicine, analyzed a sample of more than 1,000 Dallas County residents between the ages of 18 and 65 who researchers had followed for seven years. The study found that people who moved to more socioeconomically depressed neighborhoods gained weight. To reach these findings, the residents were surveyed about their impressions of their neighborhoods. The neighborhoods were also rated based on a Neighborhood Deprivation Index NDI to determine socioeconomic status a higher index indicates a more deprived neighborhood. Among the people in the study, 263 people moved to a neighborhood with a higher index, 586 moved to a lower-index neighborhood and 47 people moved to a neighborhood that had the same rating. Everyone else stayed in their same neighborhood. The people who moved to the higher-index neighborhoodsthe ones more deprived of resourcesgained more weight compared to the people who moved to a neighborhood that had the same or lower index. For every 1-unit increase in the index, residents gained about 1.41 pounds. Of the people who moved to a more deprived neighborhood, the longer they stayed there, the larger the impact on their weight. More research is needed before study authors can definitively explain the link, but they had a few speculations. The makeup of a more deprived neighborhood can encourage consumption of unhealthy foods or make it hard to stay fit, they say. Research has also linked changes in stress hormones to living in disadvantaged neighborhoods. The National Institutes of Health NIH says that living environments can encourage obesity and interfere with an unhealthy lifestyle a lack of sidewalks and safe parks, a glut of fast-food restaurants with little access to fruits and vegetables, heavy food advertising and long work hours of residents all contribute. Prior research has shown that kids who live in places where they can walk to school or libraries were significantly less likely to be obese. And a 2011 study found that families who moved to less-impoverished neighborhoods had lower levels of obesity and diabetes compared to families who stayed in their original neighborhood. The new study underlines the fact that living environments can have a great impact on body size and health. "Addressing neighborhood deprivation as a risk factor for obesity and obesity-related cardiovascular disease requires consideration of public policy that can address sources of deprivation," the study authors conclude.
