Objective:Only 47% of obese patients receive weight loss advice from their health care provider (HCP). Patients who receive weight loss advice are more likely to eat healthy foods. The food environment has also been shown to affect eating behaviors and may be a potential moderator of the effectiveness of weight loss advice in affecting eating behaviors. This study explores the moderating influence of the community food environment, potentially explaining why some patients improve their eating behaviors after receipt of weight loss advice while other patients do not.
Methods:Data were obtained from a household telephone survey of 2,211 adults in 4 New Jersey cities from two cross-sectional panels (2009-10 and 2014). Analyses were confined to 1,427 overweight and obese participants. The survey enquired about frequency of consumption of fruits, vegetables, sugar sweetened beverages (SSB) and fast food over the previous month, and receiving HCP's advice to lose weight over the past 12 months. Food environment data were purchased from InfoUSA and Nielsen and classified according to an established protocol. Stratified gamma regression analysis determined the differences in the association between receiving weight loss advice and eating behaviors by community food environment.
Results:Stratified analyses revealed that receiving advice to lose weight from a HCP was associated with a decrease in consumption of total SSB when participants lived near a small grocery store (29% lower frequency, p<.05), or far from a supermarket (29% lower frequency, p<.05), limited service restaurant (24% lower frequency, p<.05), or convenience store (62% lower frequency, p<.05). There was no association between receiving weight loss advice and SSB consumption when participants lived near supermarkets, limited service restaurants, or convenience stores. No associations were found for fruit, vegetable, and fast food consumption.
Conclusion:This study highlights the moderating role of the community food environment on eating behaviors and the effectiveness of receiving weight loss advice from a HCP. Receiving HCP weight loss advice was associated with a decrease in some unhealthy eating behaviors, but these beneficial associations varied based on proximity to outlets offering a high volume of unhealthy options.
