To describe current infant-feeding practices and current food group consumption patterns of infants and toddlers and to compare 2008 data with 2002 data to identify shifts in these practices and food consumption over time.
The Feeding Infants and Toddlers Study (FITS) 2008 is a cross-sectional survey of a national random sample of US children from birth up to age 4 years. Data for three age subgroups (infants 4 to 5.9 months and 6 to 11.9 months and toddlers 12 to 23.9 months) were used from the 2002 (n=2,884) and 2008 surveys (n=1,596).
All analyses use sample weights that reflect the US population aged 4 to 24 months. Descriptive statistics (means, proportions, and standard errors) and t tests were calculated using SUDAAN (release 9, 2005, Research Triangle Park Institute, Research Triangle Park, NC).
These data show a higher percentage of infants receiving breast milk from 4 to 11.9 months of age with a concurrent decreasing percentage of infants receiving formula, which is significantly different from data for the 9- to 11.9-month-old age group. The use of complementary foods also appears to be delayed in FITS 2008: There is a significantly lower proportion of infants consuming infant cereal at 9 to 11.9 months in FITS 2008 compared to 2002 data. Fruit and vegetable consumption remains lower than desired. Significant reductions in the percentage of infants and toddlers consuming any desserts or candy, sweetened beverages, and salty snacks were seen in 2008.
The findings presented here provide important insights to the content of messages and types of interventions that are still needed to improve the diets of infants and toddlers.
描述当前婴幼儿的喂养方式及当前食物组消费模式，并比较2008年数据与2002年数据，以确定这些喂养方式和食物消费随时间的变化。
2008年婴幼儿喂养研究（FITS）是一项对美国出生至4岁儿童的全国随机样本进行的横断面调查。使用了2002年（n = 2884）和2008年调查（n = 1596）中三个年龄亚组（4至5.9个月和6至11.9个月的婴儿以及12至23.9个月的幼儿）的数据。
所有分析均使用反映4至24个月美国人口的样本权重。使用SUDAAN（2005年第9版，三角研究园研究所，北卡罗来纳州三角研究园）计算描述性统计量（均值、比例和标准误差）以及t检验。
这些数据显示，4至11.9个月的婴儿接受母乳的比例更高，同时接受配方奶的婴儿比例下降，这与9至11.9个月年龄组的数据有显著差异。2008年FITS中辅食的使用似乎也有所延迟：与2002年数据相比，2008年FITS中9至11.9个月食用婴儿谷物的婴儿比例显著降低。水果和蔬菜的消费量仍低于预期。2008年，食用任何甜点或糖果、甜味饮料和咸味零食的婴幼儿比例显著下降。
此处呈现的研究结果为改善婴幼儿饮食仍需的信息内容和干预类型提供了重要见解。
