BackgroundThe US Department of Agriculture Child and Adult Care Food program (CACFP) recently (October 2017) updated requirements for meal reimbursement and best practice recommendations for serving nutritious meals and beverages, and minimum age-specific serving sizes for five food groups. It is not known whether CACFP-funded child-care centers are meeting the updated meal pattern requirements and best practice recommendations, and whether children are meeting nutrition recommendations based on the current 2015-2020 Dietary Guidelines for Americans (DGA).ObjectiveThis study assessed whether the recruited CACFP-funded child-care centers in this study were meeting the updated (2017) CACFP requirements regarding foods served for lunch and whether children attending these child-care centers were meeting age- and sex-specific DGA recommendations regarding foods consumed.DesignThis was a cross-sectional study using the Dietary Observation for Child Care method. Participants and settingsChildren aged 3 to 5 years (n=108) from 10 classrooms in three CACFP-funded child-care centers in Lincoln, NE, were recruited by convenience sampling during spring 2018.Measurable outcomesFood served and consumed during observed lunches in comparison with updated CACFP requirements and DGA, respectively.Statistical analysisAdjusted mean amounts of foods served from each food group were compared with age specific minimum CACFP serving size requirements. Adjusted mean amounts of foods consumed from each food group were then compared with age- and sex-specific DGA recommendations.ResultsThe recruited child-care centers were meeting the updated CACFP requirements regarding foods served but showed limited adherence to the best practice recommendations during the observed lunches. However, the overall mean intake for grains, fruits, and vegetables was significantly lower (P<0.01) than DGA recommendations. In addition, approximately 25% of the children did not consume any vegetables during their meal. ConclusionsAlthough child-care centers were meeting the updated CACFP requirements by serving the recommended amounts of foods, children were not meeting DGA-recommended intakes. Future studies are needed to explore ways to improve adherence to best practice recommendations to improve children’s consumption of healthy foods in child-care centers.  相似文献

Few child-care providers meet the national recommendations for healthful feeding practices. Effective strategies are needed to address this disparity, but research examining influences on child-care providers' feeding practices is limited. The purpose of this study was to identify determinants of child-care providers' healthful and controlling feeding practices for children aged 2 to 5 years. In this cross-sectional study, child-care providers (n=118) from 24 center-based programs (six Head Start [HS], 11 Child and Adult Care Food Program [CACFP] funded, and seven non-CACFP) completed self-administered surveys during 2011-2012. Multilevel multivariate linear regression models were used to predict seven feeding practices. Working in an HS center predicted teaching children about nutrition and modeling healthy eating; that may be attributed to the HS performance standards that require HS providers to practice healthful feeding. Providers who reported being concerned about children's weight, being responsible for feeding children, and had an authoritarian feeding style were more likely to pressure children to eat, restrict intake, and control food intake to decrease or maintain children's weight. Providers with nonwhite race, who were trying to lose weight, who perceived nutrition as important in their own diet, and who had a greater number of nutrition training opportunities were more likely to use restrictive feeding practices. These findings suggest that individual- and child-care–level factors, particularly provider race, education, training, feeding attitudes and styles, and the child-care context may influence providers' feeding practices with young children. Considering these factors when developing interventions for providers to meet feeding practice recommendations may add to the efficacy of childhood obesity prevention programs.  相似文献

ObjectiveExamine differences in dietary intake of children aged 2–5 years in early care and education (ECE) setting in the US Affiliated Pacific (USAP).DesignSecondary analysis of cross-sectional data collected by the Children's Healthy Living program.ParticipantsChildren (n = 1,423) with complete dietary records and information on the ECE setting.Main Outcome MeasuresDietary intake by ECE setting; Head Start (HS), other ECE (OE), and no ECE.AnalysisComparison of mean dietary intake across ECE settings and multivariate logistic regression to evaluate ECE setting and likelihood for meeting dietary reference intake (DRI).ResultsChildren in HS and OE settings had a significantly higher intake of several food groups and nutrients, compared with no ECE; vegetables (0.4 cup-equivalents per thousand kcals [CETK] vs 0.3 CETK; P < 0.001), fruits (0.8 CETK vs 0.6 CETK; P = 0.001), milk (0.9 CETK for HS and 1.0 CETK for OE vs 0.8 CETK; P < 0.001). Sixty-five percent of the HS group met DRI and had greater odds of meeting calcium DRI (odds ratio, 1.8; 95% confidence interval, 1.2–2.7) compared with other groups. The OE group had the lowest proportion of children meeting recommended intakes for 19 out of 25 nutrients.Conclusions and ImplicationsMean intakes of foods and nutrients for children across the USAP meet some, but not all, recommendations and intakes vary across children attending various ECE setting types. Additional research on the clinical importance of these differences and the impact of the complex food systems in the USAP may identify systematic strategies for improving diet among children.  相似文献

BackgroundFood pantry users represent a predominantly food insecure population, yet dietary intake may differ among food secure (FS), low FS, and very low FS clients. Usual intake of food groups and nutrients by food security status has not previously been compared among food pantry clients.ObjectiveThis study aimed to estimate the usual intakes of underconsumed nutrients (ie, potassium; dietary fiber; choline; magnesium; calcium; vitamins A, D, E, and C; and iron) and related food groups (ie, vegetables, fruits, whole grains, and dairy) and dietary quality, and to evaluate their relationship with food security status.DesignThis cross-sectional, secondary analysis used baseline data from a prior intervention study (Clinical Trial Registry: NCT03566095). A demographic questionnaire, the US Household Food Security Survey Module, and up to three 24-hour dietary recalls on nonconsecutive days, including weekdays and weekends, were collected.Participants/settingThis community-based study included a convenience sample of adult, midwestern food pantry clients (N=579) recruited from August to November 2014.Main outcome measuresMain outcomes evaluated were Healthy Eating Index-2010 scores and usual intakes of underconsumed nutrients and related food groups.Statistical analyses performedLinear regression models and the National Cancer Institute method, adjusting for confounders, were used to estimate associations of food security with diet quality and usual intake, respectively.ResultsBeing FS was associated with a higher whole grains HEI-2010 score and higher mean usual intake of whole grains compared with being low FS. Being FS was associated with higher usual intakes of iron and dairy compared with being very low FS. Being FS was associated with a higher mean usual intake of dark green vegetables compared with being low FS and very low FS. Usual intakes were below federal guidance for all subgroups of food security.ConclusionsAlthough food security status may differentiate dietary intake among food pantry clients, improvements are needed among all clients.  相似文献

BackgroundIndividuals consuming diets dense in fruits and vegetables consume an array of phytonutrients as well as recognized nutritional components, including vitamins, minerals, and fiber. There is a growing body of evidence that phytonutrients may play positive roles in health.ObjectiveThe purpose of this research was to estimate usual intakes of nine individual phytonutrients by Americans consuming recommended levels of fruits and vegetables compared to intakes by adults not meeting these recommendations, and to identify contributions of food sources to total phytonutrient intakes. The phytonutrients examined in this study are found predominantly in fruits and vegetables.DesignFood consumption data from the National Health and Nutrition Examination Surveys 2003-2006 and phytonutrient concentration data from US Department of Agriculture databases and the published literature were used to estimate energy-adjusted usual intakes. Student's t tests were used to compare mean energy-adjusted phytonutrient intakes between subpopulations who consumed recommended amounts of fruits and vegetables vs those who did not. Percentage contributions of each phytonutrient by food source were estimated for all adults.ResultsEnergy-adjusted intakes of all phytonutrients other than ellagic acid were considerably higher among both men and women meeting dietary recommendations for fruit and vegetable intakes compared to those not meeting the recommendations; energy-adjusted intakes of ellagic acid were higher only among women meeting vs not meeting the recommendations. For five of the nine phytonutrients (α-carotene, β-cryptoxanthin, lycopene, hesperetin, and ellagic acid), a single food accounted for 64% or more of the total intake of the phytonutrient.ConclusionsEnergy-adjusted intakes of carotenoids and flavonoids are higher among men and women whose diets conform to dietary guidance for fruits and vegetables. A limited number of foods provide the majority of these phytonutrients. Findings from this research provide important reference information on the phytonutrient contributions of a diet rich in fruits and vegetables.  相似文献

ObjectiveTo capture Child and Adult Care Food Program (CACFP) state directors’ experiences implementing federal waivers for feeding children in early care and education (ECE) settings during coronavirus disease 2019.DesignQualitative semistructured interviews.SettingVirtual interviews with state CACFP directors.ParticipantsChild and Adult Care Food Program directors from 21 states from December 2020 to May 2021.Phenomenon of InterestImplementation of state-level waivers.AnalysisQualitative thematic analysis.ResultsState directors reported that the coronavirus disease 2019 waivers allowed ECE programs to continue feeding children despite being closed or having limited enrollment. The meal pattern, noncongregate feeding, parent/guardian meal pick-up, and monitoring waivers were most frequently used by states. Challenges included maintaining integrity to CACFP meal pattern requirements, addressing the limited capacity of ECE to produce and distribute noncongregate meals, and adapting technology for virtual reviews. Suggested improvements included streamlined communication from the US Department of Agriculture, standing waivers for emergencies, ongoing flexibilities for feeding children, and strategies to increase CACFP enrollment and reduce financial viability requirements for ECE.Conclusions and ImplicationsResults indicate the need for the US Department of Agriculture to consider issuing and extending waivers, increasing ECE participation in CACFP, and ensuring timely communication and guidance on waiver tracking.  相似文献

BackgroundParents and early care and education (ECE) are the key influencers of young children’s diets, but there is limited information about how each contribute to children’s overall diet quality.ObjectiveThis study aimed to determine what proportion of children’s dietary intake occurs within the ECE setting and whether diet quality is higher at ECE centers and, consequently, on weekdays than weekends.DesignThis cross-sectional analysis of a larger cluster randomized controlled trial used multiple 24-hour dietary intakes measured through a combination of the Dietary Observation in Child Care protocol and parent-reported food diaries.Participants/settingParticipants (N=840) included children aged 3 to 4 years enrolled in ECE centers in central North Carolina for whom 24-hour dietary intake was captured via observation of meals and snacks consumed at ECE and parent-report of all remaining meals and snacks. Data were collected from 2015 to 2016.Main outcome measuresDiet quality at ECE and elsewhere was evaluated using the Healthy Eating Index 2015.Statistical analyses performedMixed-effects models were used to determine differences in mean Healthy Eating Index 2015 component and total scores. Models were adjusted for children’s age and sex and accounted for clustering within ECE centers and families.ResultsChildren consumed approximately 40% of daily energy, nutrients, and food groups at ECE centers. The mean total Healthy Eating Index 2015 score was higher for foods and beverages consumed at ECE centers (58.3±0.6) than elsewhere (52.5±0.6) (P<0.0001). The mean total Healthy Eating Index 2015 score was also higher on weekdays (58.5±0.5) than on weekends (51.3±0.5) (P<0.0001).ConclusionsChildren consume a majority of dietary intake away from ECE centers. Overall, diet quality is low, but the quality of foods consumed by children at ECE centers is higher than that consumed elsewhere. ECE centers remain an important source of nutrition and further investigation is warranted to identify ways to support both ECE centers and families to provide healthier eating environments.  相似文献

The aim of the present study was to record the percentage of children, adults and elderly women in Greece meeting food and micronutrient intake recommendations. Additionally, the present study was aiming to identify the main food contributors of micronutrient intakes and assess the degree up to which meeting food intake recommendations also ensures micronutrient intake adequacy. Dietary intake data from three studies conducted in Greece (on 9–13-year-old children; 40–60-year-old adults; and 50–75-year-old women) were used to estimate mean intakes, the percentages of subjects meeting food and nutrient intake recommendations and the contribution of six core food groups to nutrient intake adequacy. The present study showed that more than 50% of children, adults and elderly women were failing to consume the recommended portions of vegetables, dairy and grains. Furthermore, children and adults consuming the recommended portions of individual core food groups had significantly lower percentages of inadequate micronutrient intakes compared to their counterparts not meeting food intake recommendations (p < 0.05). Nevertheless, even among those consuming the recommended portions from a specific core food group, the recommended intake of the corresponding micronutrient (for which this food group is the main contributor) was not always met. Indicatively, 18.2%–44.1% and 4.2%–7.0% of the populations under study were not meeting calcium and vitamin C intake recommendations, although they were consuming the recommended portions of dairy and fruits, respectively. In conclusion, these findings highlight the importance for public health policy makers to take all necessary initiatives to support the population in achieving the recommended intakes from all core food groups, but also emphasize on food variety to ensure adequate intake for all micronutrients.  相似文献

BackgroundFood group and nutrient priorities for Special Supplemental Nutrition Program for Women, Infants, and Children (WIC) Food Package IV for children aged 2 to 4 years were described in the 2017 review of the WIC Food Package. Research has evaluated priority nutrient intake, but priority food group intake remains unknown.ObjectivesTo compare mean intake of priority food groups/subgroups of WIC children to WIC-eligible nonparticipants and higher income children. Further, we hoped to assess differences in percent contribution of food subgroups to total food group intake by WIC participation status and income.DesignCross-sectional study conducted using data from the 2011-14 National Health and Nutrition Examination Survey.Participants/settingOne thousand forty-seven children aged 2 to 4 years.Main outcome measuresMean intake reported in cup equivalents and ounce equivalents. We also looked at mean percent that food subgroups contributed to total intake within a food group. Analyses were performed for high and low priority food groups/subgroups: high = seafood, total vegetables, dark green vegetables, red/orange vegetables, whole grains, and nuts/seeds/soy; low = total starchy vegetables, other vegetables, legumes computed as vegetables, total dairy, and total protein foods.Statistical analyses performedMultivariable linear regression analysis was used evaluate the relationship between income/WIC participation and mean intake/percent food subgroups contributed to total food group intake.ResultsAmong low-income WIC-eligible children, participation in WIC was associated with greater mean intake of red/orange vegetables (0.18 ± 0.03 vs 0.01 ± 0.06 c equivalents; P < 0.05) and legumes (0.07 ± 0.01 vs 0.01 ± 0.02 c equivalents; P < 0.01). No differences in mean intake were observed between WIC children and higher income children. Grain intake of WIC children was composed of a higher percentage of whole grains (19.1% ± 1.6% vs 13.2% ± 1.5%; P < 0.01) compared with higher income children. The percent vegetable subgroups contributed to total vegetable intake varied by income; no differences were observed for dairy or protein subgroups.ConclusionsAmong low-income children, participation in WIC was associated with greater intake of certain vegetables. Participation in WIC may also help close the diet quality gap between low-income and higher income children for priority foods targeted by the WIC food package. Future research should explore socioeconomic disparities in intake of nutrient-poor foods.  相似文献

BackgroundIncome and race/ethnicity are associated with differences in dietary intakes that may contribute to health disparities among members of the US population.ObjectiveTo examine alignment of intakes of food groups and energy from solid fats, added sugars, and alcohol with the 2005 Dietary Guidelines for Americans and MyPyramid, by family income and race/ethnicity.DesignData from the National Health and Nutrition Examination Survey, a cross-sectional, nationally representative survey, for 2001-2004.Participants/settingPersons aged ≥2 years for whom reliable dietary intake data were available (n=16,338) were categorized by income (lowest, middle, and highest) and race/ethnicity (non-Hispanic white, non-Hispanic black, and Mexican American).Statistical analyses performedThe National Cancer Institute method was used to estimate the proportions of adults and children in each income and race/ethnic group whose usual intakes met the recommendations.ResultsHigher income was associated with greater adherence to recommendations for most food groups; the proportions meeting minimum recommendations among adults in the highest income group were double that observed for the lowest income group for total vegetables, milk, and oils. Fewer differences by income were apparent among children. Among the race/ethnic groups, the proportions meeting recommendations were generally lowest among non-Hispanic blacks. Marked differences were observed for milk—15% of non-Hispanic black children met the minimum recommendations compared with 42% of non-Hispanic white children and 35% of Mexican-American children; a similar pattern was evident for adults. One in five Mexican-American adults met the dry beans and peas recommendations compared with approximately 2% of non-Hispanic whites and non-Hispanic blacks. Most adults and children consumed excess energy from solid fats and added sugars irrespective of income and race/ethnicity.ConclusionsThe diets of some subpopulations, particularly individuals in lower-income households and non-Hispanic blacks, are especially poor in relation to dietary recommendations, supporting the need for comprehensive strategies to enable healthier dietary intake patterns.  相似文献

BackgroundMore than half of 3- to 6-year-old children attend child-care centers. Dietary intakes of children attending child-care centers tend to fall short of Dietary Reference Intakes (DRIs).ObjectiveOur aim was to examine macro-/micronutrient content of child-care center menus, compare menus to one third of DRIs, and determine menu differences by population density.MethodsA stratified, random, geographically proportionate sample of Oklahoma child-care centers was obtained. Child-care centers providing all-day care for 2- to 5-year-old children were contacted to complete a telephone questionnaire and asked to send in that month's menus for the 3- to 4-year-old children. Overall means and standard deviations of the nutrient content of 5 days of lunch menus were calculated. Comparisons were made to both the 1- to 3-year-old and 4- to 8-year-old DRIs. One-sample t tests compared mean nutrient content of lunches to one third of the DRIs for the overall sample and urban/rural classification. Independent t tests compared nutrient content of urban and rural lunches.Participants/settingOne hundred sixty-seven child-care centers were contacted; 83 completed the study (50% response).ResultsMenus provided statistically significantly insufficient carbohydrate, dietary fiber, iron, vitamin D, and vitamin E. Calcium was higher than the 1- to 3-year-old DRI, but lower than the 4- to 8-year-old DRI. Folate was higher than the 1- to 3-year-old DRI, but not different from the 4- to 8-year-old DRI. Sodium was higher than the DRI for both age groups. Thirty-four child-care centers (41%) were classified as urban and 49 (59%) as rural. Urban menus provided less than the 4- to 8-year-old DRI for folate, but rural child-care center menus did not.ConclusionsOklahoma child-care center menus appear to provide adequate protein, magnesium, zinc, vitamin A, and vitamin C, but may be deficient in key nutrients required for good health and proper development in preschool-aged children. These issues can be addressed by including food and nutrition practitioners in the process to ensure child-care center menus are a useful resource and nutritionally appropriate for preschool children.  相似文献

BackgroundNearly a third of young US children take multivitamin/mineral (MVM) dietary supplements, yet it is unclear how formulations compare with requirements.ObjectiveDescribe the number and amounts of micronutrients contained in MVMs for young children and compare suggested amounts on product labels to micronutrient requirements.DesignCross-sectional.SettingAll 288 MVMs on the market in the United States in the National Institutes of Health’s Dietary Supplement Label Database in 2018 labeled for children 1 to <4 years old.Main outcome measuresNumber of MVM products and amounts per day of micronutrients in each product suggested on labels compared with requirements represented by age-appropriate Daily Values (DV). Micronutrients of public health concern identified by the Dietary Guidelines for Americans (DGA) 2015-2020 (DGA 2015) and DGA 2020-2025 (DGA 2020) or those of concern for exceeding the upper tolerable intake levels.Statistical analysesNumber of products and percent DV per day provided by each micronutrient in each product.ResultsThe 288 MVMs contained a mean of 10.1 ± 2.27 vitamins and 4.59 ± 2.27 minerals. The most common were, in rank order, vitamins C, A, D, E, B6, B12; zinc, biotin, pantothenic acid, iodine, and folic acid. For micronutrients denoted by the DGA 2015 and DGA 2020 of public health concern, 56% of the 281 products containing vitamin D, 4% of the 144 with calcium, and none of the 60 containing potassium provided at least half of the DV. The upper tolerable intake level was exceeded by 49% of 197 products with folic acid, 17% of 283 with vitamin A, and 14% of 264 with zinc. Most MVMs contained many of 16 other vitamins and minerals identified in national surveys as already abundant in children’s diets.ConclusionsA reexamination of the amounts and types of micronutrients in MVMs might consider formulations that better fill critical gaps in intakes and avoid excess.  相似文献

ObjectiveExplore using food photography to assess packed lunches in a university-based Early Childhood Center and contextualize these photographs through parent interviews.MethodsAn explanatory sequential design was used. Packed lunches were photographed to assess the type and quantity of foods offered and consumed by Child and Adult Food Care Program components (fruit, vegetable, grain, and protein) and quality of foods offered using the Healthy Meal Index. Parent interviews aimed to understand motivations and behaviors related to packing lunch.ResultsData were collected on 401 lunches. Only 16.2% of lunches met all Child and Adult Food Care Program requirements. Most lunches included fruit (84%) and grains (82%), whereas fewer included vegetables (44%). Portion sizes were large, especially for grains (2.7 ± 1.5 servings). In interviews (n = 24), parents expressed tension between offering healthful items and foods they knew their child would eat, as well as concern about children going hungry.Conclusions and ImplicationsFood photography is a feasible methodology to capture parent-packed lunches for preschoolers and may have utility in nutrition education, particularly related to age-appropriate portion sizes.  相似文献

The purpose of this study was to compare the dietary intakes of children who attend child-care centers with the recommendations of the Food Guide Pyramid for Young Children. Three-day dietary records were obtained for 50 children ages 3 to 5 years old who attended nine child-care centers in central Texas. Dietary intakes during child care were measured by a researcher, and dietary intakes at home were recorded by a parent. During child care, the 3-year-old children consumed sufficient fruits and meat/alternates, but not sufficient grains, vegetables, or dairy to meet two thirds of Food Guide Pyramid for Young Children recommendations. The 4- and 5-year-old children only consumed sufficient dairy. Ninety-one percent (20 of 22) of the 3-year-old children met two thirds of their estimated energy requirements during child care, compared with 5% (1 of 20) of 4-year-old children and 25% (2 of 8) of 5-year-old children. Intakes at home did not compensate for lack of grain and vegetable consumption during child care.  相似文献

The US Department of Agriculture's Child and Adult Care Food Program (CACFP) serves 2.3 million children by providing monetary subsidies for food to participating child-care providers. This cross-sectional study tested the hypothesis that higher reimbursement rates for food result in higher food expenditures and higher nutritional quality of foods served in family child-care homes participating in CACFP. Sixty family home child-care providers were recruited in 2008-2009 from King County, Washington. Half the sample received higher reimbursements and the other half received the lower rates. Participants provided a 5-day menu of meals/snacks served and food shopping receipts. The nutritional quality of foods served was assessed from portion-standardized menus. Nutritional quality was quantified as the mean adequacy (mean percent of dietary reference intake) for seven nutrients of concern for child health. Food expenditures were calculated by linking menus with receipts. Student's t tests for independent samples and general linear models were used to test for between-group differences. The two groups of providers were socioeconomically and demographically similar with comparable professional backgrounds. However, higher reimbursement providers had significantly greater menu expenditures than the lower reimbursement group ($2.36 vs $1.96/child/day; P=0.031). Reimbursement level was not associated with a difference in calories, but menus of higher reimbursement providers showed a significantly higher mean nutritional adequacy (64.5% vs 56.3%; P=0.033). The finding that reimbursement rates were positively associated with food expenditures and the nutritional quality of foods served suggests that raising CACFP reimbursements can improve child nutrition.  相似文献

The objective of the current modeling analysis was three-fold: (1) to examine usual nutrient intakes in children when eggs are added into dietary patterns that typically do not contain eggs; (2) to examine usual nutrient intakes with the addition of eggs in the Child and Adult Care Food Program (CACFP) school breakfast; and (3) to examine nutrient adequacy when eggs are included in routine breakfast patterns and with the addition of eggs to the CACFP school breakfast program. Dietary recall data from the National Health and Nutrition Examination Survey 2011–2016 (children aged 1–18 years-old; n = 9254; CACFP n = 159) were used in the analysis. The usual intakes of pantothenic acid, riboflavin, selenium, and vitamin D increased ≥10 percent (relative to the baseline values) with the addition of one egg at breakfast. The usual intakes of protein and vitamin A at breakfast were also increased by more than 10 percent compared to the baseline values with the addition of two eggs. Similar outcomes were observed with the addition of eggs to the CACFP school breakfast. The percent of children above the adequate intake for total choline increased to 43.6 and 57.8% with one and two eggs, respectively, compared to 22.6% at the baseline. The addition of eggs at breakfast can contribute to nutrient intakes and overall dietary adequacy and play a role in public health initiatives aimed at increasing the intake of under-consumed nutrients and nutrients of concern.  相似文献

BackgroundEven in an era of obesity and dietary excess, numerous shortfall micronutrients have been identified in the diets of US children and adolescents. To help tailor strategies for meeting recommendations, it is important to know what foods contribute greatly to micronutrient intakes. Data are lacking on specific contributions made by added nutrients.ObjectiveOur aims were to examine the impact of fortification on nutrient adequacy and excess among US children and adolescents and to rank food sources of added nutrient intake and compare rankings with those based on total nutrient intake from foods.Design and statistical analysesData were from 7,250 respondents 2 to 18 years old in the National Health and Nutrition Examination Survey 2003-2006. Datasets were developed that distinguished nutrient sources: intrinsic nutrients in foods; added nutrients in foods; foods (intrinsic plus added nutrients); and total diet (foods plus supplements). The National Cancer Institute method was used to determine usual intakes of micronutrients by source. The impact of fortification on the percentages of children having intakes less than the Estimated Average Requirement and more than the Upper Tolerable Intake Level was assessed by comparing intakes from intrinsic nutrients to intakes from intrinsic plus added nutrients. Specific food sources of micronutrients were determined as sample-weighted mean intakes of total and added nutrients contributed from 56 food groupings. The percentage of intake from each grouping was determined separately for total and added nutrients.ResultsWithout added nutrients, a high percentage of all children/adolescents had inadequate intakes of numerous micronutrients, with the greatest inadequacy among older girls. Fortification reduced the percentage less than the Estimated Average Requirement for many, although not all, micronutrients without resulting in excessive intakes. Data demonstrated the powerful influence of fortification on food-source rankings.ConclusionsKnowledge about nutrient intakes and sources can help put dietary advice into a practical context. Continued monitoring of top food sources of nutrients and nutrient contributions from fortification will be important.  相似文献

Background

Licensed child-care centers represent an opportunity to positively influence children's health behaviors. Valid and easy-to-use measures of the child-care environment are needed to assess the influence of environmental change on health.

Objective

To develop and validate a self-administered survey to assess the nutrition and physical activity environment of child-care centers, and to identify domains that may be evaluated adequately through self-report.

Design

A survey was developed to assess four areas related to nutrition and physical activity: center policies, practices related to the social environment, physical environment, and nutrition quality. Development involved review of the literature, existing measures, and regulations/standards as well as collaboration with a working group. The survey was pilot tested and feedback was sought from expert consultants. It was administered statewide and validated against a menu rating tool, interviews with a center director, and a direct observation tool that was developed for this study.

Participants/setting

Participating sites were drawn from Child and Adult Care Food Program-participating licensed Connecticut child-care centers serving 13 or more children aged 3 to 5 years. Survey responses from 146 center directors were included, as were 62 center menus, and director interviews and observational data from 33 sites.

Primary outcomes/statistical analyses

Criterion validity of the survey was assessed through percent agreement with mirroring items in the additional measures. Healthy and unhealthy food scores were calculated for menu and survey tools, and Pearson correlations were computed.

Results

Percent agreement with criterion outcomes ranged from 39% to 97%, with 61% of items achieving agreement ≥80%. Agreement was highest for nutrition and policy domains, and lowest for physical activity and barriers to promoting health. Correlations between food scores across measures were moderate.

Conclusions

The self-report survey demonstrated adequate criterion validity. We make recommendations for improving validity of low-agreement items and for the use of more labor-intensive evaluation procedures for domains not adequately assessed through self-report.  相似文献

Background

Improving the nutritional quality of food, including beverages, served in early care and education settings should enhance children’s diet quality. However, few studies have explored the relationship between what is served and consumed in family child-care homes (FCCHs).

Objective

To describe the nutritional quality of food served to children in FCCHs and to assess the extent to which children eat what is served.

Design

This study was a cross-sectional analysis using baseline data (n=166) from a cluster-randomized controlled trial (2013-2016).

Participants/setting

Eligible FCCHs in central North Carolina had to have at least two children between 18 months and 4 years, have been in business for at least 2 years, and serve at least one meal and one snack.

Main outcome measures

Food was captured using the Diet Observation at Child Care protocol.

Statistical analyses

Frequencies, means, and multivariate analysis were used to examine the relationship between food served and consumed by food groups and by Healthy Eating Index (HEI-2010).

Results

Children consumed between 61% and 80% of what was served, with vegetables having the lowest percent consumed (61.0%). Total HEI-2010 score for food served was 63.6 (10.4) and for food consumed was 61.7 (11.5) out of a 100-point maximum. With regards to food served, FCCH providers came close to meeting HEI-2010 standards for dairy, whole fruit, total fruit, and empty calories. However, providers appeared to fall short when it came to greens and beans, seafood and plant proteins, total vegetables, whole grains, and fatty acids. They also exceeded recommended limits for sodium and refined grains.

Conclusions

Although FCCHs are serving some healthy food, mainly fruit, dairy, and few empty calories, there is room for improvement with regards to vegetables, grains, seafood and plant protein, fatty acids, and sodium. Future trainings should help providers find ways to increase the serving and consumption of these foods.  相似文献
