Long-term weight loss could be linked to how far you live from a food store – Business Insider India

Columbus [Ohio], March 9 (ANI): According to new research, being able to walk to a nearby food retail shop may be a key determinant in long-term weight loss following bariatric surgery.Nevertheless, researchers discovered that merely residing near a food shop isn't a surefire route to long-term weight loss, especially if the market serves largely processed convenience foods.

The findings were published in Surgery for Obesity and Related Diseases and Obesity Surgery.

A closer look at store products affected whether that proximity was beneficial, showing that living within a five-minute walk of a store with a low-quality selection of foods was actually linked to less weight loss at the two-year post-operative point.

The research team examined neighborhood characteristics and other social determinants of health that may help or hinder continued weight loss in the two years after bariatric surgery.

The analysis included select data from the electronic health records of all patients who received bariatric surgery at The Ohio State University Wexner Medical Center from 2015 to 2019 in Franklin County, Ohio. Data included race, insurance type, procedure and percentage of total weight loss from two to 24 months after surgery.

Researchers combined health records with census and county data, which enabled the team to count not just the number of food stores, parks/recreational areas and fitness facilities in the county, but precisely where they were relative to patients' home addresses.

Bariatric surgery reduces the size of the stomach and leads to rapid weight loss, which requires patients to initially eat a soft diet in small quantities and gradually transition back to a more varied diet, being coached for six months by a dietitian and nurse practitioner.

Previous research has shown that living in healthier areas has helped people manage their weight, but very few studies had looked at the social determinants of health that affect patients who have had a significant surgery to achieve their weight loss, she said.

The patient sample consisted of 772 patients who had undergone one of two types of stomach-reduction surgery. Of those, 60% were white and 82% were women.

The initial study found that while Black surgery patients had higher levels of poverty and unemployment than white patients, consistent with previous studies, those variables did not negatively affect weight loss outcomes. Nor did living near open spaces or fitness and recreation facilities.

Access to a higher number of food stores within a 10-minute walk was linked to a greater percentage of weight loss among all patients. But there was some nuance: Black patients with access to a higher number of food stores within a 10-minute walk experienced greater weight loss over two years. For white patients, the best distance for sustained weight-loss was a five-minute walk from stores.

For all patients, living within a five- or 10-minute walk from moderate- or high-diversity stores had no effect on weight loss, but having one low-diversity store within a five-minute walk or up to two low-diversity stores 10 minutes away was linked to less sustained weight loss.

The researchers noted that living near these stores was not an indicator that patients actually shopped at the markets closest to their homes - but the nature of the most available food stores could be an indicator of larger economic forces at play.

"The real goal is to figure out how to make linkages from the clinic to the community and the community to the clinic," Pratt said, suggesting Ohio State could partner with stores to upgrade their food selection and with fitness facilities to provide patient discounts.

"This is really a starting point to figuring out how we can aid patients in Franklin County and, eventually, beyond, to make sure post-operative weight loss is equitable, and the resources are equitable, for all patients following surgery."
