Here’s why weight gain or loss is not impacted by built environments

The findings of a brand new examine led by the University of Washington recommend that individuals do not acquire or drop extra pounds as a result of they stay close to a fast-food restaurant or grocery store. It discovered residing in a extra “walkable”, dense neighbourhood probably solely has a small impression on weight.

The examine was revealed earlier this month within the International Journal of Obesity. These “built-environment” facilities have been seen in previous analysis as important contributors to losing a few pounds or tending towards weight problems.

The concept seems apparent: If you reside subsequent to a fast-food restaurant, you may eat there extra and thus acquire weight. Or, when you’ve got a grocery store close by, you may store there, eat more healthy and thus drop extra pounds. Live in a neighborhood that makes strolling and biking simpler and you will get out, train extra and burn extra energy.

The new examine based mostly on anonymized medical data from greater than 100,000 Kaiser Permanente Washington sufferers didn’t discover that residing close to supermarkets or fast-food eating places had any impression on weight. However, city density, such because the variety of homes in a given neighborhood, which is intently linked to neighborhood “walkability” seems to be the strongest ingredient of the constructed atmosphere linked to alter in physique weight over time.

“There’s a whole lot of prior work that has recommended that residing near a grocery store may result in decrease weight acquire or extra weight reduction, whereas residing near numerous fast-food eating places may result in weight acquire,” stated James Buszkiewicz, lead writer of the examine and a analysis scientist within the UW School of Public Health.

He added, “Our analyses of the meals atmosphere and density collectively means that the extra individuals there are in an space — larger density — the extra supermarkets and fast-food eating places are positioned there. And we discovered that density issues to weight acquire, however not proximity to quick meals or supermarkets. So, that appears to recommend that these different research have been probably observing a false sign.”

The UW-led examine discovered that individuals residing in neighborhoods with larger residential and inhabitants density weigh much less and have much less weight problems than individuals residing in less-populated areas. And that did not change over a five-year interval of examine.

“On the entire, when desirous about methods to curb the weight problems epidemic, our examine suggests there’s probably no easy repair from the constructed atmosphere, like placing in a playground or grocery store,” stated Buszkiewicz, who did his analysis for the examine whereas a graduate pupil within the UW Department of Epidemiology.

Rather than “one thing magical concerning the constructed atmosphere itself” influencing the load of these people, Buszkiewicz stated, community-level variations in weight problems are extra probably pushed by systematic elements apart from the constructed atmosphere — resembling earnings inequality, which is commonly the figuring out issue of the place individuals can afford to stay and whether or not they can afford to maneuver.

“Whether you may afford to eat a nutritious diet or to have the time to train, these elements most likely outweigh the issues we’re seeing by way of the constructed atmosphere impact,” he stated.

The researchers used the Kaiser Permanente Washington data to collect physique weight measurements a number of occasions over a five-year interval. They additionally used geocodable addresses to determine neighborhood particulars, together with property values to assist set up socioeconomic standing, residential unit density, inhabitants density, highway intersection density, and counts of supermarkets and fast-food eating places accessible inside a brief stroll or drive.

“This examine actually leverages the ability of huge information,” stated Dr. David Arterburn, co-author and senior investigator at Kaiser Permanente Washington Health Research Institute. “Our use of anonymized well being care data permits us to reply essential questions on environmental contributions to weight problems that will have been unattainable prior to now.”

This examine is a part of a 12-year, joint UW and Kaiser Permanente Washington analysis undertaking known as Moving to Health. The objective of the examine, in response to the UW’s undertaking web site, is to supply population-based, complete, rigorous proof for policymakers, builders and shoppers relating to the options of the constructed atmosphere which are most strongly related to the chance of weight problems and diabetes.

“Our subsequent objective is to raised perceive what occurs when individuals transfer their main residence from one neighborhood to a different,” Arterburn stated.

Arterburn added, “When our neighborhood traits change quickly — resembling shifting to a way more walkable residential space — does which have an essential impact on our physique weight?”
