Cross-sectional analysis of eating patterns and snacking in the US Feeding Infants and Toddlers Study 2008.

OBJECTIVE: To explore eating patterns and snacking among US infants, toddlers and pre-school children. DESIGN: The Feeding Infants and Toddlers Study (FITS) 2008 was a cross-sectional national survey of children aged 6-47 months, weighted to reflect US age and racial/ethnic distributions. Dietary data were collected using one multiple-pass 24h recall. Eating occasions were categorized as meals, snacks or other (comprised of all feedings of breast milk and/or infant formula). The percentage of children consuming meals and snacks and their contribution to total energy, the number of snacks consumed per day, energy and nutrients coming from snacks and the most commonly consumed snacks were evaluated by age. SETTING: A national sample of US infants, toddlers and pre-school children. SUBJECTS: A total of 2891 children in five age groups: 6-8 months (n 249), 9-11 months (n 256), 12-23 months (n 925), 24-35 months (n 736) and 36-47 months (n 725). RESULTS: Snacks were already consumed by 37 % of infants beginning at 6 months; by 12 months of age, nearly 95 % were consuming at least one snack per day. Snacks provided 25 % of daily energy from the age of 12 months. Approximately 40 % of toddlers and pre-school children consumed fruit and cow's milk during snacks; about 25 % consumed 100 % fruit juice. Cookies were introduced early; by 24 months, 57 % consumed cookies or candy in a given day. CONCLUSIONS: Snacking is common, contributing significantly to daily energy and nutrient needs of toddlers and pre-school children. There is room for improvement, however, with many popular snacking choices contributing to excess sugar.

Added Sugars in School Meals and the Diets of School-Age Children.

Research is limited on added sugars in school meals and children's dietary intakes after the 2015-2020 Dietary Guidelines for Americans (DGA) recommended that added sugars be limited to less than 10% of total calories. This analysis uses data from the School Nutrition and Meal Cost Study (SNMCS) to examine levels of added sugars in: (1) school meals and (2) children's dietary intakes at breakfast, lunch, and over 24 h on school days. SNMCS data were collected in the 2014-2015 school year after updated nutrition standards for school meals were implemented. Most schools exceeded the DGA limit for added sugars at breakfast (92%), while 69% exceeded the limit at lunch. The leading source of added sugars in school meals (both breakfasts and lunches) was flavored skim milk. More than 62% of children consumed breakfasts that exceeded the DGA limit, and almost half (47%) consumed lunches that exceeded the limit. Leading sources of added sugars in the breakfasts consumed by children were sweetened cold cereals and condiments and toppings; leading sources of added sugars in children's lunches were flavored skim milk and cake. Over 24 h, 63% of children exceeded the DGA limit. These findings show that school meals and children's dietary intakes are high in added sugars relative to the DGA limit and provide insights into the types of foods that should be targeted in order to decrease levels of added sugars.

Updated Nutrition Standards Have Significantly Improved the Nutritional Quality of School Lunches and Breakfasts.

BACKGROUND: Implementation of updated nutrition standards for school meals began during school year (SY) 2012-2013. The standards were designed to improve the nutritional quality of the meals and their consistency with the Dietary Guidelines for Americans. OBJECTIVE: To assess the nutritional quality of school lunches and breakfasts after the updated standards were in place and compare it with the nutritional quality of the meals before the updated standards. DESIGN: School menu data were used from two cross-sectional, nationally representative studies of schools participating in the National School Lunch Program during SY 2014-2015 (School Nutrition and Meal Cost Study) and SY 2009-2010 (fourth School Nutrition Dietary Assessment Study). PARTICIPANTS/SETTING: The analysis used 1 week of school menu data from 1,206 schools at lunch and 1,110 schools at breakfast for SY 2014-2015, and 884 schools at lunch and 802 schools at breakfast for SY 2009-2010. OUTCOME MEASURES: Healthy Eating Index 2010 scores were estimated. STATISTICAL ANALYSES: Descriptive analyses were conducted to estimate mean Healthy Eating Index 2010 total and component scores for school meals. Scores are expressed as a percentage of maximum possible scores. Two-tailed t tests were used to assess differences in scores before and after updated standards were in place. RESULTS: Total Healthy Eating Index 2010 scores for school lunches and breakfasts increased significantly after the updated standards. Between SY 2009-2010 and SY 2014-2015, the total score for school lunches increased from 58% of the maximum score to 82%, and the total score for school breakfasts increased from 50% to 71% (P<0.05). For both meals, component scores increased by more than 20 percentage points for whole grains, refined grains, and empty calories, as well as for greens and beans for lunches and whole fruit and sodium for breakfasts. CONCLUSIONS: The updated nutrition standards for schools meals significantly improved the nutritional quality of the meals and their consistency with the Dietary Guidelines for Americans.

Differences in Diet Quality between School Lunch Participants and Nonparticipants in the United States by Income and Race.

Prior research has shown that participation in the United States' National School Lunch Program (NSLP) is associated with consuming higher-quality lunches and diets overall, but little is known about differences by income and race/ethnicity. This analysis used 24 h dietary recall data from the School Nutrition and Meal Cost Study to examine how NSLP participation affects the diet quality of students in different income and racial/ethnic subgroups. Diet quality at lunch and over 24 h was assessed using the Healthy Eating Index (HEI)-2010, where higher scores indicate higher-quality intakes. HEI-2010 scores for NSLP participants and nonparticipants in each subgroup were estimated, and two-tailed t-tests were conducted to determine whether participant-nonparticipant differences in scores within each subgroup were statistically significant. NSLP participants' lunches received significantly higher total HEI-2010 scores than those of nonparticipants for lower-income, higher-income, non-Hispanic White, and non-Hispanic Black students, suggesting that participating in the NSLP helps most students consume healthier lunches. These significantly higher total scores for participants' lunch intakes persisted over 24 h for higher-income students and non-Hispanic White students but not for lower-income students or students of other races/ethnicities. For NSLP participants in all subgroups, the nutritional quality of their 24 h intakes was much lower than at lunch, suggesting that the positive influence of the NSLP on their overall diet quality was negatively influenced by foods consumed the rest of the day (outside of lunch).

Randomized Controlled Trial of Healthy Harlem's Get Fit Program: An After-School Intervention for Childhood Overweight and Obesity in the Harlem Children's Zone.

Background: Although the increases in overweight and obesity observed for several decades have appeared to have leveled off, the prevalence of overweight and obesity remains exceptionally high among children of color. This article estimates the effect of Healthy Harlem's Get Fit-a 12-week after-school program aimed at helping students improve physical activity and eating habits-on BMI and weight status of adolescents. Methods: Participants were 436 students who had overweight or obesity in 12 Harlem Children's Zone after-school programs in New York. The evaluation was a randomized controlled trial where students were assigned to an intervention group that received Get Fit plus Prevention services or a control group that only received Prevention services in 2013 or 2014. Impacts were assessed on BMI z-score, percentage with overweight or obesity, and percentage with obesity using regression analysis. Results: Relative to the control group, students randomized to Get Fit experienced a decrease in BMI z-score (mean difference = -0.04; p = 0.02). The percentage of students with overweight or obesity was also lower (mean difference = -5.3; p = 0.02), but there was no effect on the percentage of students with obesity. Get Fit had an impact on BMI for girls, but not boys. Conclusions: Get Fit improved middle- and high-school students' BMI outcomes and weight status. Schools continue to face pressure to allocate time for physical education and activity while meeting their academic demands, underscoring the importance of after-school student-level interventions like Get Fit.

Timing of introduction of complementary foods and beverages and growth, size, and body composition: a systematic review.

BACKGROUND: The systematic review described in this article was conducted as part of the USDA and Department of Health and Human Services Pregnancy and Birth to 24 Months Project. OBJECTIVES: The aim was to describe the relationship between timing of introduction of complementary foods and beverages (CFBs) and growth, size, and body-composition outcomes across the life span. METHODS: The literature was searched and selected using predetermined criteria. Data were extracted and risk of bias assessed for each included study. Evidence was qualitatively synthesized, conclusion statements were developed, and the strength of the evidence was graded. RESULTS: Eighty-one articles were included in this systematic review that addressed timing of CFB introduction relative to growth, size, and body-composition outcomes from infancy through adulthood. Moderate evidence suggests that introduction of CFBs between the ages of 4 and 5 mo compared with ∼6 mo is not associated with weight status, body composition, body circumferences, weight, or length among generally healthy, full-term infants. Limited evidence suggests that introduction of CFBs before age 4 mo may be associated with higher odds of overweight/obesity. Insufficient evidence exists regarding introduction at age ≥7 mo. CONCLUSIONS: Although several conclusions were drawn in this systematic review, additional research is needed to address gaps and limitations in the evidence on timing of introduction of CFBs and growth, size, and body composition, such as randomized controlled trials that examine multiple outcomes and/or CFB introduction between the ages of 4 and 6 mo, and research that accounts for potential confounders such as feeding practices and baseline growth status and considers issues of reverse causality.

Types and amounts of complementary foods and beverages consumed and growth, size, and body composition: a systematic review.

BACKGROUND: Systematic reviews (SRs) were conducted by the Nutrition Evidence Systematic Review (NESR) team for the USDA's and the Department of Health and Human Services' Pregnancy and Birth to 24 Months Project. OBJECTIVES: The aim was to describe the SRs examining the relationship between types and amounts of complementary foods and beverages (CFBs) and growth, size, and body-composition outcomes. METHODS: The NESR team collaborated with subject matter experts to conduct this SR. The literature was searched and screened using predetermined criteria. For each included study, data were extracted and risk of bias was assessed. The evidence was qualitatively synthesized to develop a conclusion statement, and the strength of evidence was graded. RESULTS: This SR includes 49 articles that examined type, amount, or both of CFBs consumed and growth, size, and body-composition outcomes. Moderate evidence suggests that consuming either different amounts of meat, meat instead of iron-fortified cereal, or types of CFBs with different fats or fatty acids does not favorably or unfavorably influence growth, size, or body composition. In relation to overweight/obesity, insufficient evidence is available with regard to the intake of meat or CFBs with different fats or fatty acids. Limited evidence suggests that type and amount of fortified infant cereal does not favorably or unfavorably influence growth, size, body composition, or overweight/obesity. Limited evidence suggests that sugar-sweetened beverage consumption during the complementary feeding period is associated with increased obesity risk in childhood but is not associated with other measures of growth, size, or body composition. Limited evidence showed a positive association between juice intake and infant weight-for-length and child body mass index z scores. Insufficient evidence is available on other CFBs or dietary patterns in relation to outcomes. CONCLUSIONS: Although several conclusions were drawn, additional research is needed that includes randomized controlled trials, examines a wider range of CFBs, considers issues of reverse causality, and adjusts for potential confounders to address gaps and limitations in the evidence.

Complementary feeding and developmental milestones: a systematic review.

BACKGROUND: Systematic reviews were conducted as part of the USDA and the US Department of Health and Human Services Pregnancy and Birth to 24 Months Project to examine the relation between complementary feeding and developmental milestones. OBJECTIVES: The aim of this study was to describe systematic reviews examining the relationship between timing of introduction of complementary foods and beverages (CFB), and the types and amounts of CFB consumed, and developmental milestones. METHODS: The literature was searched using 4 databases (PubMed, Cochrane, Embase, and CINAHL) to identify articles that met predetermined criteria for inclusion. Data extraction and risk of bias assessment were conducted for each included study. The body of evidence for each systematic review was qualitatively synthesized to develop a conclusion statement, and the strength of evidence was graded. RESULTS: Three included articles (1 randomized controlled trial; 2 observational studies) examined timing of introduction of CFB. Eight included articles (3 randomized controlled trials; 5 observational studies) examined types and amounts of CFB. There was insufficient evidence to draw conclusions about the relation between either timing of CFB introduction or types and amounts of CFB, and developmental milestones. CONCLUSIONS: The ability to draw conclusions about the relationship between complementary feeding and developmental milestones was restricted by an inadequate amount of evidence with potential for issues with reverse causality and wide variation in design, type/age of outcome assessment, exposure assessment, and reported results. Additional research to address these gaps and limitations would be useful.

Complementary feeding and bone health: a systematic review.

BACKGROUND: Proper nutrition during infancy and toddlerhood is crucial for supporting healthy growth and development, including bone health. Complementary feeding is the process that starts when human milk or infant formula is complemented by other foods and beverages, beginning during late infancy and continuing to 24 mo of age. OBJECTIVES: This article aims to describe systematic reviews (SRs) conducted by the Nutrition Evidence Systematic Review team for the USDA and the Department of Health and Human Services Pregnancy and Birth to 24 Months Project to answer these questions: what is the relationship between 1) timing of introduction of complementary foods and beverages (CFBs) or 2) types and/or amounts of CFBs consumed and bone health? Methods: The literature was searched with the use of 4 databases (CINAHL, Cochrane, Embase, and PubMed) to identify articles published from January 1980 to July 2016 that addressed these topics and met predetermined criteria for inclusion. For each study, data were extracted and risk of bias was assessed. The evidence was qualitatively synthesized to develop a conclusion statement, and the strength of the evidence was graded. RESULTS: Three articles addressed the timing of introduction of CFBs and bone health during childhood (through 18 y of age), and 2 addressed the types and/or amounts of CFBs consumed relative to bone health. CONCLUSIONS: Insufficient evidence was available to draw conclusions about the relationships between the timing of CFB introduction and types and/or amounts of CFBs consumed and bone health. Therefore, a grade was not assignable for these SRs. The ability to draw conclusions was limited by an overall lack of research, failure to adjust for several key confounding factors, and heterogeneity in studies with regard to methodology, subject populations, and results. Additional research is needed that addresses these gaps and limitations.

Complementary feeding and food allergy, atopic dermatitis/eczema, asthma, and allergic rhinitis: a systematic review.

BACKGROUND: Nutrition during infancy and toddlerhood may influence health and disease prevention across the life span. Complementary feeding (CF) starts when human milk or infant formula is complemented by other foods and beverages, beginning during infancy and continuing to age 24 mo. OBJECTIVES: The aim of this study was to describe systematic reviews conducted for the USDA and the Department of Health and Human Services Pregnancy and Birth to 24 Months Project to answer the following question: What is the relationship between the timing of the introduction of complementary foods and beverages (CFBs), or types and amounts of CFBs consumed, and the development of food allergy, atopic dermatitis/eczema, asthma, and allergic rhinitis? METHODS: The literature was searched using 4 databases (CINAHL, Cochrane, Embase, PubMed) to identify articles published from January 1980 to February 2017 that met predetermined inclusion criteria. For each study, data were extracted and risk of bias was assessed. The evidence was qualitatively synthesized to develop a conclusion statement, and the strength of the evidence was graded. RESULTS: Thirty-one included articles addressed the timing of CFB introduction, and 47 articles addressed the types and amounts of CFBs consumed. CONCLUSIONS: Moderate evidence suggests that there is no relationship between the age at which CF first begins and the risk of developing food allergy, atopic dermatitis/eczema, or childhood asthma. Limited to strong evidence, depending on the specific food, suggests that introducing allergenic foods in the first year of life (after 4 mo) does not increase the risk of food allergy and atopic dermatitis/eczema but may prevent peanut and egg allergy. There is not enough evidence to determine a relationship between diet diversity or dietary patterns and atopic disease. Research is needed to address gaps and limitations in the evidence on CF and atopic disease, including research that uses valid and reliable diagnostic measures and accounts for key confounders and potential reverse causality.

Complementary feeding and micronutrient status: a systematic review.

BACKGROUND: Proper nutrition during early life is critical for growth and development. OBJECTIVES: The aim was to describe systematic reviews conducted by the Nutrition Evidence Systematic Review team for the USDA and the Department of Health and Human Services Pregnancy and Birth to 24 Months Project to answer the following: What is the relation between 1) timing of introduction of complementary foods and beverages (CFBs) or 2) types and/or amounts of CFBs consumed and micronutrient status (iron, zinc, vitamin D, vitamin B-12, folate, and fatty acid status)? METHODS: A literature search identified articles from developed countries published from January 1980 to July 2016 that met the inclusion criteria. Data were extracted and risk of bias assessed. Evidence was qualitatively synthesized to develop a conclusion statement, and the strength of the evidence was graded. RESULTS: Nine articles addressed the timing of CFB introduction and 31 addressed types or amounts or both of CFBs. Moderate evidence suggests that introducing CFBs at age 4 mo instead of 6 mo offers no advantages or disadvantages in iron status among healthy full-term infants. Evidence is insufficient on the timing of CFB introduction and other micronutrient status outcomes. Strong evidence suggests that CFBs containing iron (e.g., meat, fortified cereal) help maintain adequate iron status or prevent deficiency in the first year among infants at risk of insufficient iron stores or low intake. Benefits for infants with sufficient iron stores (e.g., infant formula consumers) are less clear. Moderate evidence suggests that CFBs containing zinc (e.g., meat, fortified cereal) support zinc status in the first year and CFB fatty acid composition influences fatty acid status. Evidence is insufficient with regard to types and amounts of CFBs and vitamin D, vitamin B-12, and folate status, or the relation between lower-iron-containing CFBs and micronutrient status. CONCLUSIONS: Several conclusions on CFBs and micronutrient status were drawn from these systematic reviews, but more research that addresses specific gaps and limitations is needed.

Addressing the epidemic of childhood obesity through school-based interventions: what has been done and where do we go from here?

Schools are ideal settings for implementing multi-component programs to prevent and control childhood obesity. Thoughtful improvements to proven strategies, coupled with careful evaluation, can contribute to accumulation of evidence needed to design and implement the next generation of optimal interventions.

Sources of energy and nutrients in the diets of infants and toddlers.

OBJECTIVE: To identify major sources of energy and 24 nutrients and dietary constituents in the diets of US infants and toddlers and to describe shifts in major nutrient sources as children age. DESIGN: Data from 24-hour recalls collected in the 2002 Feeding Infants and Toddlers Study were analyzed to determine the percentage contribution of foods and supplements to total intakes of energy, nutrients, and other dietary constituents. A total of 3,586 unique foods and dietary supplements were reported. Reported foods and supplements were classified into 71 groups based on similarities in nutrient content and use. Nine-hundred seventy-nine food mixtures were disaggregated into their ingredients and ingredients were classified into one of the 71 groups using the same decision rules that guided classification of foods analyzed at the whole food level. SUBJECTS/SETTING: A national random sample of 3,022 US infants and toddlers 4 to 24 months of age. STATISTICAL ANALYSES PERFORMED: The population proportion formula was used to determine the percentage contribution of each of the 71 groups to total intakes. This was done by summing the weighted amount of a given nutrient provided by a given group for all individuals in the sample and dividing by the total weighted amount of that nutrient consumed by all individuals from all foods and supplements. Groups that provided at least 1% of the nutrient in question were rank-ordered. Separate tabulations were prepared for three age groups (4-5 months, 6-11 months, and 12-24 months). RESULTS: Infant formula, breast milk, and milk are major contributors of energy and most nutrients in the diets of infants and toddlers. Among toddlers, juices and fruit-flavored drinks are the second and third most important sources of energy. Fortified foods make substantial contributions to intakes of many essential nutrients, and these contributions increase as children age. For example, among toddlers, fortified grain-based foods make substantial contributions to intakes of vitamin A, iron, and folate, relative to foods that are naturally rich in these nutrients. Supplements also make substantial contributions to intakes of vitamins and selected minerals, particularly among toddlers. CONCLUSIONS: In assessing dietary intakes of infants and toddlers, dietetics professionals need to carefully consider contributions of fortified foods and supplements. Dietetics professionals should educate caregivers of infants and toddlers about the importance of foods (rather than just nutrients) in promoting health and about the importance of early feeding practices in the development of lifelong eating habits. Caregivers should be encouraged to avoid relying on fortified foods and supplements to meet nutrient needs and educated about the potential risk of excessive intakes. Caregivers of toddlers and infants over 4 to 6 months of age who are consuming solid foods should be encouraged to feed a wide variety of fruits, vegetables, and whole grains, as well as foods naturally rich in iron.

Average portions of foods commonly eaten by infants and toddlers in the United States.

OBJECTIVES: To examine average portion sizes consumed per eating occasion by infants and toddlers. Average portions reported for toddlers were compared to average portions for comparably aged children reported in the 1994 to 1996 and 1998 Continuing Survey of Food Intakes by Individuals. In addition, reported average portions were compared with minimum required portion sizes for meals served to infants and toddlers in the Child and Adult Care Food Program (CACFP). DESIGN: Data from 24-hour recalls collected in the 2002 Feeding Infants and Toddlers Study (FITS) were analyzed. Average portion sizes were determined for major food groups and individual foods that were reported by at least 5% of the population. Most foods were reported separately; however, sandwiches were disaggregated into their components. Gram weights of portions consumed were converted, on a food-by-food basis, to household units so that foods with different volume-to-weight ratios could be analyzed together. SUBJECTS/SETTING: A national random sample of 3,022 US infants and toddlers 4 to 24 months of age. STATISTICAL ANALYSES PERFORMED: For each food and food group, average portion sizes per eating occasion were computed for up to six age groups. An average per-eating occasion portion was determined for each child who consumed a given food by summing the total amount of food consumed over the day and dividing by the number of eating occasions. These estimates were then summed across all children who consumed the food and divided by the total number of consumers. The number of eating occasions was defined as the total number of times a child had anything to eat or drink during the day, excluding eating occasions that included only water and/or supplements. RESULTS: For most foods, there was a gradual increase in the average portion as age increased. Average portions reported for FITS toddlers were consistent with those reported for comparably aged children in the most recent Continuing Survey of Food Intakes by Individuals. The average portions reported for FITS infants and toddlers were consistent with CACFP-recommended portion sizes for formula, juice, meats, and cheese. For milk (toddlers only), cereal, breads, fruits, and vegetables, average portions reported in FITS were consistently larger than CACFP portion sizes. Distributions showed that, in many cases, the per-eating occasion portion sizes of 50% to 90% of FITS infants and toddlers exceeded the CACFP portion sizes. CONCLUSIONS: Dietitians, pediatricians, and health educators can use the data presented in this article to provide guidance to parents and caregivers about reasonable portion sizes for infants and toddlers. The data should also be useful to those who plan meals for infants and toddlers in child care settings and to researchers studying dietary intakes of infants and toddlers. Advice about reasonable portion sizes should always be tempered with appropriate cautions about avoiding coercive "clean your plate" feeding practices. Parents and caregivers should be encouraged to offer infants and toddlers appropriate portions of healthful foods from the basic food groups, with a special emphasis on fruits, vegetables, and whole grains, and allow them to eat until they are satiated.

Feeding Infants and Toddlers Study: do vitamin and mineral supplements contribute to nutrient adequacy or excess among US infants and toddlers?

OBJECTIVE: To report the prevalence of dietary supplement use in a random sample of US infants 4 to 24 months of age, and to compare demographic characteristics, usual nutrient intakes, and food patterns of supplement users and nonusers. DESIGN: Data from 24-hour recalls collected for the 2002 Feeding Infants and Toddlers Study were analyzed. Recalls included nutrient contributions from dietary supplements as well as all foods and beverages. We estimated usual energy and nutrient intakes of supplement users and nonusers, as well as the prevalence of nutrient adequacy and excess in the two groups. We also compared demographic characteristics and food patterns of supplement users and nonusers and, for supplement users, estimated the proportion of total intake provided by foods and the proportion provided by supplements. SUBJECTS: A national random sample of 3,022 infants and toddlers age 4 to 24 months, including 430 vitamin and/or mineral supplement users and 2,592 nonusers. STATISTICAL ANALYSIS: We compared means, percentile distributions, and proportions by age and supplement subgroup, and applied the Dietary Reference Intakes to assess usual nutrient intakes. We conducted regression analysis to determine which population characteristics predict the use of dietary supplements in this population. RESULTS: Overall, 8% of infants age 4 to 5 months received some type of dietary supplement. The prevalence of supplement use increased with age, to 19% among infants 6 to 11 months and 31% among toddlers 12 to 24 months. The vast majority of supplement users (97%) received only one type of supplement, most commonly a multivitamin and/or mineral supplement. Vitamin/mineral supplement use among infants and toddlers was associated with being a first-born child and being reported by the primary caretaker as being a picky eater. Characteristics that were independent predictors of supplement use were living in the Northeast, being male, and living in a household with fewer children. We found no significant differences between supplement users and nonusers in mean daily intakes of nutrients or nutrient density from foods alone, and few differences in food consumption. Overall, the prevalence of inadequate intakes was low (<1% to 2%). However, 65% of supplement nonusers and 9% of supplement users had vitamin E intakes less than the Estimated Average Requirement. Excessive intakes (ie, intakes above the Tolerable Upper Intake Level) were noted for both supplement users and nonusers for vitamin A (97% and 15% of toddlers) and zinc (60% and 59% of older infants and 68% and 38% of toddlers) as well as for folate among supplement users (18% of toddlers). CONCLUSIONS: Generally, healthy infants and toddlers can achieve recommended levels of intake from food alone. Dietetics professionals should encourage caregivers to use foods rather than supplements as the primary source of nutrients in children's diets. Vitamin and mineral supplements can help infants and toddlers with special nutrient needs or marginal intakes achieve adequate intakes, but care must be taken to ensure that supplements do not lead to excessive intakes. This is especially important for nutrients that are widely used as food fortificants, including vitamin A, zinc, and folate.

Relationship between portion size and energy intake among infants and toddlers: evidence of self-regulation.

OBJECTIVES: To assess whether dietary intakes of infants and young toddlers show evidence of energy self-regulation. DESIGN: Data from 24-hour recalls collected in the 2002 Feeding Infants and Toddlers Study were analyzed. Multivariate regressions were used to explore the relationship between portion size and usual energy intake as well as the relationship between portion size, number of eating occasions, number of unique foods, and energy density. SUBJECTS/SETTING: A national random sample of 3,022 US infants and toddlers 4 to 24 months of age. STATISTICAL ANALYSES PERFORMED: To measure variability in portion size, an average portion size z score was computed for each child in the sample, across 45 different food groups. The number of eating occasions was defined as the total number of times a child had anything to eat or drink during the day, excluding eating occasions that included only water and/or supplements. The total number of unique foods in a day was defined as the number of unique food codes included in the 24-hour recall, and energy density was computed as kilocalories/gram, including all foods, beverages, and water. Linear regression models were used to assess the effect of portion size and other self-regulation mechanisms on energy intake and to assess the effect of these self-regulation mechanisms on portion size. Separate analyses were performed for three age groups: 4 to 5 months, 6 to 11 months, and 12 to 24 months. RESULTS: A significant negative association was found for all age groups between the number of eating occasions and average portion size z scores, indicating that children who eat less often during the day consume larger-than-average-portion sizes and children who eat more often during the day consume smaller-than-average portions. For infants (11 months and younger), a significant negative association was noted between energy density and average portion size z scores, indicating that, as the energy density of the diet goes down, infants consume larger-than-average portions and, as the energy density of the diet goes up, they consume smaller-than-average portions. Among infants 6 to 11 months, there was a significant positive relationship between portion size and the number of unique foods consumed. For toddlers, there was no association between average portion size z scores and energy density, suggesting that energy self-regulation mechanisms are diminished in this age group. CONCLUSIONS: Our findings confirm the presence of energy self-regulation among infants and young toddlers. These findings can be used to assure parents and caregivers that infants have an innate ability to regulate energy intake. At the same time, it is important to educate parents and caregivers about the potential for environmental cues to diminish natural hunger-driven eating behaviors, even among young toddlers. Dietetics professionals should emphasize the potential adverse effects that coercive feeding behaviors can have on children's innate ability to regulate energy intake. This includes not only admonitions to "clean your plate," but overrestriction of intake that may be motivated by concerns that children are overeating.

Feeding infants and toddlers study: What foods are infants and toddlers eating?

OBJECTIVE: To describe the food consumption patterns of US infants and toddlers, 4 to 24 months of age. DESIGN: Descriptive analysis of data collected in the 2002 Feeding Infants and Toddlers study based on telephone interviews and 24-hour dietary recalls. SUBJECTS: A national random sample of 3,022 infants and toddlers age 4 to 24 months. STATISTICAL ANALYSES PERFORMED: The percentage of infants and toddlers consuming foods from specific food groups was estimated for six age groups, using a single 24-hour recall. RESULTS: Infants as young as 7 months of age showed food patterns that have been observed in older children and adults. From 18% to 33% of infants and toddlers between ages 7 and 24 months consumed no discrete servings of vegetables, and 23% to 33% consumed no fruits. French fries were one of the three most common vegetables consumed by infants 9 to 11 months of age. By 15 to 18 months, french fries were the most common vegetable. Almost half (46%) of 7- to 8-month-olds consumed some type of dessert, sweet, or sweetened beverage, and this percentage increased as age increased. By 19 to 24 months, 62% of toddlers consumed a baked dessert, 20% consumed candy, and 44% consumed a sweetened beverage. APPLICATIONS: Parents and caregivers should be encouraged to offer a wide variety of vegetables and fruits daily, with emphasis on dark green, leafy, and deep yellow vegetables and colorful fruits. They should offer desserts, sweets, sweetened beverages, and salty snacks only occasionally, offering nutrient-dense, age-appropriate foods as alternatives (eg, fruit, cheese, yogurt, and cereals). Water, milk, and 100% fruit juices should be offered as alternative beverages. Because family food choices influence what foods are offered to children, family-based approaches to developing healthy eating habits may be helpful.

Food consumption patterns of infants and toddlers: where are we now?

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.

Food consumption patterns of young preschoolers: are they starting off on the right path?

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.

The Feeding Infants and Toddlers Study 2008: study design and methods.

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.
