研究社区工作成年人样本中快餐消费、饮食质量和体重之间的关系。对参与工作现场营养干预的成年人的人体测量、调查和饮食数据进行横断面和前瞻性分析。参与者自我报告每周快餐消费的频率。使用健康饮食指数-2010 (HEI-2010)，根据基线和 6 个月收集的饮食回忆计算营养摄入量和饮食质量。美国明尼苏达州明尼阿波利斯大都会医疗中心。 200 名年龄在 18 岁至 60 岁之间的成年人。从横截面来看，快餐消费与较高的每日总能量摄入量（β = 72·5，P = 0·005）、空卡路里（β = 0·40，P = 0·006）和BMI（β = 0·73，P = 0·011）以及较低的HEI-2010分数（β = -1·23，P = 0·012）、蔬菜总量（β = -0·14， P = 0·004），全谷物（β = -0·39，P = 0·005），纤维（β = -0·83，P = 0·002），镁（β = -6·99，P = 0·019）和钾（β = -57·5，P = 0·016）。 6个月以上，快餐消费的变化与能量摄入或BMI的变化不显着相关，但与蔬菜总摄入量显着负相关（β = -0·14，P = 0·034）。快餐消费频率与较高的能量摄入和较差的饮食质量显着相关。六个月内快餐摄入量的变化很小，并且与整体饮食质量或体重指数没有显着相关。
To examine the association between fast-food consumption, diet quality and body weight in a community sample of working adults. Cross-sectional and prospective analysis of anthropometric, survey and dietary data from adults recruited to participate in a worksite nutrition intervention. Participants self-reported frequency of fast-food consumption per week. Nutrient intakes and diet quality, using the Healthy Eating Index-2010 (HEI-2010), were computed from dietary recalls collected at baseline and 6 months. Metropolitan medical complex, Minneapolis, MN, USA. Two hundred adults, aged 18–60 years. Cross-sectionally, fast-food consumption was significantly associated with higher daily total energy intake (β = 72·5, P = 0·005), empty calories (β = 0·40, P = 0·006) and BMI (β = 0·73, P =0·011), and lower HEI-2010 score (β = −1·23, P =0·012), total vegetables (β = −0·14, P =0·004), whole grains (β = −0·39, P =0·005), fibre (β = −0·83, P =0·002), Mg (β = −6·99, P =0·019) and K (β = −57·5, P =0·016). Over 6 months, change in fast-food consumption was not significantly associated with changes in energy intake or BMI, but was significantly inversely associated with total intake of vegetables (β = −0·14, P =0·034). Frequency of fast-food consumption was significantly associated with higher energy intake and poorer diet quality cross-sectionally. Six-month change in fast-food intake was small, and not significantly associated with overall diet quality or BMI.
