Patients who receive weight loss advice from a health care provider (HCP) are more likely to eat healthy. The food environment affects eating behaviors. This study explored how the community food environment may moderate the relationship between HCP advice to lose weight and eating behaviors. Data were obtained from a household telephone survey in 4 New Jersey cities from two cross-sectional panels (2009-10 and 2014). Analyses were limited to 1427 overweight and obese participants. Self-reports assessed frequency of consumption of fruits, vegetables, sugar sweetened beverages, and fast food. Community food data were purchased from InfoUSA and Nielsen and classified according to previously established protocol. Stratified gamma regression analysis determined the differences in the association between receiving weight loss advice and eating behaviors stratified by community food environment. Stratified analyses revealed that receiving advice to lose weight from a HCP was associated with lower reported consumption of total sugar-sweetened beverages, soda, and sweetened fruit drinks when participants lived near a small grocery store, or far from a supermarket, limited service restaurant, or convenience store. There were no associations between receiving weight loss advice and sugar sweetened beverage consumption when participants lived near supermarkets, limited service restaurants, or convenience stores. There were no associations with fruit, vegetable, salad or fast-food consumption, regardless of the community food environment. Food environment may play a critical role in moderating the association between HCP advice and eating behaviors. Interventions that enhance the community food environment may help convert HCP advice into improved eating behaviors.
从医疗保健提供者（HCP）处获得减肥建议的患者更有可能健康饮食。食物环境会影响饮食行为。本研究探讨了社区食物环境如何调节HCP的减肥建议与饮食行为之间的关系。数据来自新泽西州4个城市的两次横断面调查（2009 - 10年和2014年）的家庭电话调查。分析仅限于1427名超重和肥胖参与者。自我报告评估了水果、蔬菜、含糖饮料和快餐的消费频率。社区食物数据从InfoUSA和尼尔森公司购买，并根据先前制定的方案进行分类。分层伽马回归分析确定了按社区食物环境分层的接受减肥建议与饮食行为之间关联的差异。分层分析显示，当参与者居住在小型杂货店附近、或远离超市、有限服务餐厅或便利店时，从HCP处获得减肥建议与报告的总含糖饮料、苏打水和加甜水果饮料的较低消费量相关。当参与者居住在超市、有限服务餐厅或便利店附近时，接受减肥建议与含糖饮料消费之间没有关联。无论社区食物环境如何，与水果、蔬菜、沙拉或快餐消费均无关联。食物环境可能在调节HCP建议与饮食行为之间的关联中起关键作用。改善社区食物环境的干预措施可能有助于将HCP的建议转化为更好的饮食行为。
