目的：在“快餐”餐厅进食的人数增加了，这与肥胖有关。这项研究调查了在快餐店附近生活或工作是否与体重有关。方法：对1033名明尼苏达州居民进行电话调查，评估身高和体重、在餐厅就餐的频率以及工作和家庭住址。结果：在快餐店就餐与生孩子、高脂肪饮食和体重指数(BMI)呈正相关。与蔬菜摄入量、体力活动呈负相关。“快餐”餐厅离家或工作地点近与在“快餐”餐厅就餐或体重指数无关。“非快餐”餐厅的接近程度与BMI无关，但与在这些餐厅就餐的频率有关。结论：未能发现“快餐”餐厅的接近程度与肥胖之间的关系可能是由于方法上的缺陷，例如“快餐”或“接近”的操作定义，或餐馆接近程度的同质性。或者，“快餐”餐厅的激增可能并不是肥胖的一个强大的独特原因。
Objective: Eating at "fast food" restaurants has increased and is linked to obesity. This study examined whether living or working near "fast food" restaurants is associated with body weight.Methods: A telephone survey of 1033 Minnesota residents assessed body height and weight, frequency of eating at restaurants, and work and home addresses. Proximity of home and work to restaurants was assessed by Global Index System (GIS) methodology.Results: Eating at "fast food" restaurants was positively associated with having children, a high fat diet and Body Mass Index (BMI). It was negatively associated with vegetable consumption and physical activity. Proximity of "fast food" restaurants to home or work was not associated with eating at "fast food" restaurants or with BMI. Proximity of "non-fast food" restaurants was not associated with BMI, but was associated with frequency of eating at those restaurants.Conclusion: Failure to find relationships between proximity to "fast food" restaurants and obesity may be due to methodological weaknesses, e.g. the operational definition of "fast food" or "proximity", or homogeneity of restaurant proximity. Alternatively, the proliferation of "fast food" restaurants may not be a strong unique cause of obesity.
