RESUMEN
OBJECTIVE: Describe the study design, data collection methods, 24-hour dietary recall protocol, and sample characteristics of the Feeding Infants and Toddlers Study (FITS) 2008. DESIGN: A cross-sectional study designed to obtain information on the diets and feeding patterns of US infants, toddlers, and preschoolers ages birth to 47 months. Telephone interviews with parents and caregivers were conducted from June 2008 through January 2009 and included a household interview to recruit the household and collect information on household and child demographics and nutrition-related characteristics, and a dietary interview, including a 24-hour dietary recall collected using the 2008 Nutrition Data System for Research. A second dietary recall was collected on a random subsample to estimate usual nutrient intake distributions. Data collection instruments were built on those used in FITS 2002, with expanded survey content to address emerging issues in childhood nutrition and obesity. The dietary protocol was improved to increase reporting accuracy on portion sizes, and a bridging study was conducted to test effects of the changes in the food model booklet and protocol since FITS 2002 (n=240 cases aged 4 to 23 months). SUBJECTS: A national random sample of 3,273 infants, toddlers, and preschoolers from birth up to age 4 years, with 2 days of dietary intake data for 701 cases. RESULTS: Among sampled households with an age-eligible child, the response rate was 60% for the recruitment interview. Of recruited households, the response rate for the dietary interview was 78%. CONCLUSIONS: The FITS 2008 provides rigorous, well-tested methods and survey questions for nutrition researchers to use in other dietary studies of young children. FITS 2008 findings on the food and nutrient intakes of US children from birth up to age 4 years can inform dietetics practitioners, pediatric health practitioners, and policymakers about the dietary issues of young children.

OBJECTIVES: 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. DESIGN: 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). STATISTICAL METHODS: 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). RESULTS: 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. CONCLUSIONS: 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.

OBJECTIVE: To describe the food consumption patterns of US children aged 2 and 3 years. DESIGN: Descriptive analysis of data collected in the Feeding Infants and Toddlers Study 2008 based on a single 24-hour dietary recall collected by telephone. SUBJECTS: A national random sample of children aged 2 and 3 years (n=1,461). STATISTICAL ANALYSES PERFORMED: The percentage of children consuming foods from specific food groups was estimated for the full sample of children aged 2 and 3 years and separately by year of age. RESULTS: About a third of 2-year-olds and a quarter of 3-year-olds consumed whole milk at least once in a day. About 70% of 2- and 3-year-olds consumed vegetables as a distinct food item at least once in day. French fries and other fried potatoes were the most commonly consumed vegetable. Almost three quarters of children (73%) consumed fruit as a distinct food item at least once in a day, and 59% consumed 100% juice. Fresh fruit was the most commonly consumed type of fruit. About 85% of children consumed some type of sweetened beverage, dessert, sweet, or salty snack in a day. Percentages of children consuming such foods were consistently higher for 3-year-olds than for 2-year-olds. CONCLUSIONS: Parents and caregivers should be encouraged to expose young children to a wide variety of fruits and vegetables, whole grains, low-fat dairy products, and healthier fats, and to limit consumption of low-nutrient, energy-dense foods and beverages. Dietary guidance should stress the fact that children in this age group have high nutrient needs and relatively low energy requirements, leaving little room for such foods. Parents need advice that is specific, practical, and actionable.

BACKGROUND: Concerns about the diets of school-aged children and new nutrition recommendations for the US population have increased interest in the nutritional quality of meals available through the National School Lunch Program and School Breakfast Program. OBJECTIVE: This article updates national estimates of the food energy and nutrient content of school meals and compares these estimates to federal nutrient standards established under the 1995 School Meals Initiative for Healthy Children. DESIGN: Data were collected as part of the third School Nutrition Dietary Assessment Study, a nationally representative cross-sectional study fielded during school year 2004-2005. Menu and recipe data for a typical school week were collected in a mail survey with telephone assistance. Nutrient information for common commercially prepared food items was obtained from manufacturers, to supplement the Food and Nutrient Database for Dietary Studies used to analyze the data. Analyses were conducted for meals offered and meals served to (selected by) children. SUBJECTS/SETTING: Samples of 130 public school districts that offered federally subsidized school meals, and 398 schools within those districts, participated in the study. Foodservice managers in each school completed a menu survey. STATISTICAL ANALYSES PERFORMED: Descriptive tabulations present weighted means, proportions, and standard errors for elementary, middle, and high schools, and for all schools combined. RESULTS: Most schools offered and served meals that met the standards for protein, vitamins, and minerals. Fewer than one third of schools met the standards for energy from fat or saturated fat in the average lunch, whereas three fourths or more met the fat standards in school breakfasts. For both meals, average levels of sodium were high and fiber was low relative to Dietary Guidelines for Americans 2005 recommendations. CONCLUSIONS: For school meals to meet nutrient standards and promote eating behaviors consistent with the Dietary Guidelines, future policy, practice, and research should focus on reducing levels of fat and sodium and increasing fiber.

BACKGROUND: Children's food intakes do not meet dietary recommendations. Meals offered through the National School Lunch Program and School Breakfast Program make substantial contributions to school-aged children's diets. OBJECTIVES: This article describes foods offered in school meals and consumed by children at lunch and breakfast, and differences in foods consumed by children who did and did not participate in the school meal programs. DESIGN: Data were collected as part of the third School Nutrition Dietary Assessment Study, a cross-sectional, nationally representative study conducted in 2005. School menu surveys were used to identify the foods offered in school meals, and 24-hour dietary recalls were used to assess the foods children consumed. SUBJECTS/SETTING: Foodservice managers in 398 public schools and 2,314 children (grades 1 to 12) from 287 of these schools participated in the study. STATISTICAL ANALYSES PERFORMED: Descriptive tabulations report percentages of daily menus that offered and percentages of children that consumed specific food groups and foods at lunch and breakfast. Two-tailed t tests were used to assess differences between school meal program participants and nonparticipants. RESULTS: Most school menus offered nonfat or 1% milk, fruit or 100% juice, and vegetables daily. Starchy vegetables were more common than dark green/orange vegetables or legumes. School lunch participants were significantly more likely than nonparticipants to consume milk, fruit, and vegetables, and significantly less likely to consume desserts, snack items, and beverages other than milk or 100% juice. At breakfast, participants were significantly more likely than nonparticipants to consume milk and fruit (mainly 100% juice), and significantly less likely to consume beverages other than milk or 100% juice. CONCLUSIONS: Consumption of school meals is positively related to children's intakes of key food groups at lunch and breakfast. Offering more fresh fruit, whole grains, and a greater variety of vegetables could lead to additional health benefits.
