Nutrient and nontraditional food intakes by Zambian children in a controlled feeding trial.

ABSTRACT: Many programs aim to alleviate vitamin A deficiency. Biofortification is an approach to improve provitamin A carotenoid concentrations of staple crops in some developing countries. In rural Zambia, maize accounts for the majority of energy intake. Provitamin A-biofortified (orange) maize has been released in Zambia.This study quantified food intake of Zambian children from records collected in a feeding trial in 2012 in order to compare adoption of orange maize and a new vegetable (green beans) with white maize and traditional foods.One hundred thirty-six children with a mean age of 71.5 +/- 6.9 months were fed three meals a day for 6 days a week for 15 weeks at four feeding centers. Breakfast consisted of maize porridge, and lunch and dinner were stiff porridge (nshima) with various side dishes (relishes). There were three treatment groups, which received orange maize and placebo oil, white maize and placebo oil, or white maize and a daily vitamin A supplement. Food was weighed before and after consumption. Nutritionists were trained to interview the children's caregivers about the previous day's intake using dietary recalls. Nine dietary recalls for each child were recorded and analyzed.Total food intake did not differ among the groups (p = .31) and energy intakes on Sundays (< or = 880 kcal) were below recommendations. Nshima intake was lower in the orange-maize group (p = .008), largely due to a genotype effect. Intakes of relish, green bean, and porridge did not differ among the groups (p > .19). Dietary recalls revealed that children living in sites closer to the main road consumed more on Sundays than children living about 8 km from the main road, but less in the evenings when children were off site.The intakes of energy of these Zambian children were low. Implementation and adoption of new and biofortified foods is possible with promotion.

Project description:BackgroundThe US Dietary Guidelines will expand in 2020 to include infants and toddlers. Understanding current dietary intakes is critical to inform policy.ObjectiveThe purpose of this analysis was to examine the usual total nutrient intakes from diet and supplements among US children.MethodsThe Feeding Infants and Toddlers Study 2016 is a national cross-sectional study of children aged <48 mo (n = 3235): younger infants (birth to 5.9 mo), older infants (6-11.9 mo), toddlers (12-23.9 mo), younger preschoolers (24-36.9 mo), and older preschoolers (36-47.9 mo) based on the use of a 24-h dietary recall. A second 24-h recall was collected from a representative subsample (n = 799). Energy, total nutrient intake distributions, and compliance with Dietary Reference Intakes were estimated with the use of the National Cancer Institute method.ResultsDietary supplement use was 15-23% among infants and toddlers and 35-45% among preschoolers. Dietary intakes of infants were adequate, with mean intakes exceeding Adequate Intake for all nutrients except vitamins D and E. Iron intakes fell below the Estimated Average Requirement for older infants (18%). We found that 31-33% of children aged 12-47.9 mo had low percentage of energy from total fat, and >60% of children aged 24-47.9 mo exceeded the saturated fat guidelines. The likelihood of nutrient inadequacy for many nutrients was higher for toddlers: 3.2% and 2.5% greater than the Adequate Intake for fiber and potassium and 76% and 52% less than the Estimated Average Requirement for vitamins D and E, respectively. These patterns continued through older ages. Intakes exceeded the Tolerable Upper Intake Level of sodium, retinol, and zinc across most age groups.ConclusionsDietary intakes of US infants are largely nutritionally adequate; concern exists over iron intakes in those aged 6-11.9 mo. For toddlers and preschoolers, high intake of sodium and low intakes of potassium, fiber, and vitamin D and, for preschoolers, excess saturated fat are of concern. Excess retinol, zinc, and folic acid was noted across most ages, especially among supplement users.

Project description:BackgroundMany updates to young child feeding recommendations have been published over the past decade, but concurrent intake trends have not been assessed.ObjectiveThe aim of this study was to evaluate adequacy and trends in energy and nutrient intakes of US infants and children aged 0-47.9 mo through use of Feeding Infants and Toddlers Study (FITS) data from 2002, 2008, and 2016.MethodsFITS are cross-sectional surveys of parents/caregivers of infants and young children (FITS 2002, n = 2962; FITS 2008, n = 3276; FITS 2016, n = 3235). Dietary intakes were assessed by telephone with trained interviewers using the Nutrition Data System for Research. Mean ± SE nutrient intakes were calculated. Diet adequacy was assessed with the nutrient adequacy ratio (NAR) for 17 nutrients and the corresponding mean adequacy ratio.ResultsEnergy and macronutrient intakes were generally stable across surveys, but significant decreases for saturated fat and total sugars and an increase in fiber were observed among 6-11.9-mo-olds and 12-23.9-mo-olds (P-trend < 0.0001). Mean sodium intakes exceeded Adequate Intakes (AI) for all ages, whereas fiber intakes were universally below the AI. Nutrients with the lowest NAR values were vitamin D (range 0.41-0.67/1.00) and vitamin E (range 0.60-0.79/1.00 for 2008 and 2016). For iron, infants aged 6-11.9 mo had the lowest NAR values at 0.77-0.88/1.00, compared to 0.85-0.89/1.00 for 12-47.9-mo-olds. Potassium was low from 12 to 47.9 mo (NAR range 0.55-0.63/1.00 across survey years). The nutrients with the greatest decline in mean intakes were iron and vitamins D and E among 6-11.9-mo-olds, and vitamin D and potassium among 12-23.9-mo-olds in 2016 compared to 2002.ConclusionsThe diets of US infants and young children were generally adequate for most micronutrients and stable over time, but sodium intakes were too high, and nutrient gaps still existed, especially for vitamins D, E, and fiber across ages and for iron among infants.

Project description:BackgroundThis is the first study on dietary intakes of infants and young children in the Eastern Mediterranean Region, a region that is currently witnessing the nutrition transition. It aims at characterizing food consumption patterns amongst 0-4 year old children in Lebanon, evaluating their macro- and micronutrient intakes and assessing adherence to dietary recommendations.MethodsBased on a national cross-sectional survey in 2012 (n = 866), the study collected data on sociodemographic and anthropometric characteristics, and one 24-hour dietary recall was administered. Nutrient intakes were compared with reference values: Estimated Average Requirement (EAR), Adequate Intake (AI) and Acceptable Macronutrient Distribution Range (AMDR).ResultsMilk was the highest contributor to energy intake (EI) in infants (95.8 and 56.5% in 0-5.9 months and 6-11.9 months old infants, respectively), while its intake was lower among toddlers and preschoolers (35.4 and 15.1%, respectively). In contrast, intakes of sweets and sweetened beverages were the highest in preschoolers compared to younger children, contributing 18.5% EI in preschoolers. Compared to dietary guidelines, the lowest dietary adherence was found for vegetables (17.8-20.7%) and fruits (14.4-34.3%). Protein intake was within the recommendations for the vast majority of children. Although total fat intake was lower in toddlers and preschoolers compared to infants, more than 40% of toddlers and preschoolers exceeded the AMDR for fat and 87.3% of preschoolers exceeded the upper limit for saturated fat. Only 3.6% of toddlers and 11.5% of preschoolers exceeded the AI level for dietary fiber. Micronutrient intake assessment showed that mean intakes in infants exceeded the AI for all micronutrients, except for vitamin D and magnesium. In toddlers, vitamin D and calcium were below the EAR among 84.7, and 44.6%, respectively. In preschoolers, most of the children (91.9%) had inadequate intakes of vitamin D, and a third had inadequate intakes of folate, calcium and vitamin A.ConclusionsThis study identified priority issues for nutrition intervention in infants and young children in Lebanon. Concerted multi-stakeholder efforts are needed to instill heathier food consumption and nutrient intake patterns early in life.
