预计食品价格会影响膳食摄入量，然而，以前的研究结果好坏参半，很少有基于全国代表性数据的。我们使用来自个人食物摄入持续调查（CSFII; 1994-1998）的6759名儿童（2-9岁）和1679名青少年（10-18岁）的数据，研究了快餐价格指数（FF-PI）和水果蔬菜价格指数（FV-PI）与美国儿童和青少年膳食摄入量和BMI的关系。FE-PI和FV-PI与个人有关，CSFII饮食数据通过城市级地理编码。主要结果包括所选营养素和食物组的摄入量、快餐消费指数（FF-CI）、使用2005年健康饮食指数（HE）的饮食质量和BMI。在儿童（2-9岁）中，较高的FF-PI（1美元）与较低的FF-CI摄入量相关（beta +/- SE：-0.9 +/- 0.3计数/天），HEI较高（6.6 +/- 2.5），纤维（2.7 +/- 0.7 g/d），钙（225.7 +/- 52.3 mg/d），乳制品（172.5 +/- 36.2 g/d）和水果和蔬菜（113.3 +/- 23.4杯当量/d）的摄入量较高。FV-PI与纤维摄入量呈负相关（β +/- SE：-3.3 +/- 1.5 g/d），与BMI呈正相关（4.3 +/- 1.2 kg/m2）。不太一致的结果归因于FV-PI和青少年（10-18岁）。低收入和高收入家庭之间的显著关联几乎同样平衡，观察到食品价格和家庭收入之间存在一些显著的相互作用，特别是在儿童（2-9岁）中。我们的研究结果表明，在2-9岁的美国儿童中，较高的FE-PI与较好的饮食质量相关，而较高的FV-PI与较高的BMI和较低的纤维摄入量相关。协会不同的家庭收入在儿童的许多饮食摄入量变量。J.营养141：304-311，2011.
Food prices are expected to affect dietary intakes, however, previous findings are mixed and few are based on nationally representative data. We examined the associations of price indices of fast foods (FF-PI) and fruits and vegetables (FV-PI) with dietary intakes and BMI among U.S. children and adolescents using data from the Continuing Survey of Food Intakes by Individuals (CSFII; 1994-1998) for 6759 children (2-9 y) and 1679 adolescents (10-18 y). FE-PI and FV-PI were linked to individuals, CSFII dietary data through city-level geocodes. Main outcomes included intakes of selected nutrients and food groups, a fast food consumption index (FF-CI), diet quality using the 2005 Healthy Eating Index (HE)), and BMI. Among children (2-9 y), a higher FF-PI (by $1) was associated with intakes of lower FF-CI (beta +/- SE: -0.9 +/- 0.3 count/d), higher HEI (6.6 +/- 2.5), higher intakes of fiber (2.7 +/- 0.7 g/d), calcium (225.7 +/- 52.3 mg/d), dairy (172.5 +/- 36.2 g/d), and fruits and vegetables (113.3 +/- 23.4 cup equivalents/d). FV-PI was inversely related to fiber intake (beta +/- SE: -3.3 +/- 1.5 g/d) and positively associated with BMI (4.3 +/- 1.2 kg/m(2)). Less consistent findings were ascribed to FV-PI and among adolescents (10-18 y). Significant associations were almost equally balanced between low and high family income groups, with some significant interactions between food prices and family income observed, particularly among children (2-9 y). Our findings suggest that among U.S. children aged 2-9 y, higher FE-PI is associated with better dietary quality, whereas higher FV-PI is linked to higher BMI and lower fiber intake. Associations varied by family income in children for many dietary intake variables. J. Nutr. 141: 304-311, 2011.
