BACKGROUND: Information is needed on the minimum energy density and feeding frequency of complementary foods that can provide adequate energy intakes (EIs) for healthy breastfed children. OBJECTIVES: The objectives of the study were to evaluate the effects of various energy densities and feeding frequencies of complementary foods on EI from these foods, breast milk consumption, and total EI from both sources. DESIGN: During 9 separate, randomly ordered dietary periods lasting 3-6 d each, we measured intakes of food and breast milk by 18 healthy breastfed children 8-11 mo of age who, 3, 4, or 5 times/d, were fed porridge with a coded energy density of 0.5, 1.0, or 1.5 kcal/g. Food intake was measured by weighing the feeding bowl before and after meals, and breast milk intake was measured by test weighing. RESULTS: The mean amounts of complementary foods consumed were inversely related to their energy density and positively related to the number of meals/d (P < 0.001 for both); EIs from foods were positively related to both factors. Breast milk intake decreased slightly but progressively, with greater energy density and feeding frequency of complementary foods; total EIs (kcal/d) increased in relation to both factors (P < 0.001 for both). CONCLUSIONS: The energy density and feeding frequency of complementary foods affect infants' total daily EI and breast milk consumption. Recommendations can be developed for the appropriate combinations of these dietary factors that are compatible with adequate EI, although longer-term effects of complementary feeding practices on breast milk intake and breastfeeding duration need further community-based studies.  相似文献

The aim of this study was to test the ability of two new products, an instant infant flour and a food supplement containing amylases, to increase energy and micronutrient intakes of infants older than 6 months. Three groups of 48 infants were randomly constituted. Infants in groups 1 and 2 consumed at least twice a day gruel made either from the instant flour or from the food supplement. Infants from the control group received complementary foods prepared in the usual way. Each infant was surveyed during a whole day in order to measure feeding frequencies and characteristics as well as amounts of the different types of complementary foods consumed. Foods consumed by infants in the two experimental groups differed considerably in energy, micronutrient density and in consistency from the home-made complementary foods. Due to the incorporation of amylases, gruels made from the food supplement had a higher energy density, a more appropriate consistency and resulted in higher intakes per meal than gruels made from instant flour. In comparison with home-made complementary foods, both experimental products resulted in significantly higher energy and nutrient intakes. The two experimental products appeared to increase sufficiently both energy and nutrient intakes of infants to complement their breastmilk intake.  相似文献

The effect of different energy densities of complementary foods on breast milk consumption is not well understood. In this study, we tested the hypothesis that provision of fortified spread (FS), a micronutrient fortified, energy-dense (22 kJ/g), ready-to-use food, to Malawian infants would not decrease their breast milk intake more than a traditional corn + soy blended flour (CSB). Forty-four healthy 6-mo-old infant and mother pairs were enrolled in a prospective, parallel group, investigator-blinded, randomized controlled complementary feeding trial. Infants were randomized to receive 25 g/d of FS, 50 g/d of FS, or 72 g/d of CSB. The primary outcome was the difference in breast milk intake after 1 mo of complementary feeding as measured by the dose-to-mother deuterium oxide dilution technique. Outcomes were compared using repeated measures ANOVA. A total of 41 mother-infant pairs completed the study. At enrollment, 88% of the infants had received corn porridge. At baseline, the infants consumed 129 +/- 18 g.kg body wt(-1) x d(-1) (mean +/- SD) of breast milk. After 1 mo of complementary feeding with 25 g/d FS, 50 g/d FS, or 72 g/d CSB, their breast milk consumption was 115 +/- 18 g.kg body wt(-1) x d(-1), a significant reduction; however, the effects of the complementary foods did not differ from one another (F-value model = 4.33, P = 0.0008 for effect of time and P = 0.69 for effect of type of food). The results suggest that complementary feeding of Malawian infants with FS has the same effect on their breast milk intake as complementary feeding with traditional CSB porridge.  相似文献

Adoption of the recommended breast-feeding and complementary feeding behaviors and access to the appropriate quality and quantity of foods are essential components of optimal nutrition for infants and young children between ages 6 and 24 mo. Iron, zinc and vitamin B-6 are deficient in complementary food diets in Bangladesh, Ghana, Guatemala, Mexico and Peru. Low intakes of iron are consistent with a high prevalence of anemia seen in this age group. The adequacy of observed intakes for calcium, vitamin A, thiamin, folate and vitamin C depends on the age range in question and the set of requirements used in the assessment. The lipid content of many complementary food diets is low. In addition to providing essential fatty acids, lipids are needed for the absorption of fat-soluble vitamins and also enhance the texture, flavor and aroma of foods, which may lead to increased intake. The relative roles of palatability, micronutrient deficiency and morbidity-induced anorexia in the appetite of infants and young children are not known. However, even among children who were growth retarded and had a total energy deficit compared with requirements, up to 25% of food offered was not consumed. This indicates that dietary quality rather than quantity is the key aspect of complementary food diets that needs to be improved. Targeted fortification or the production of complementary foods fortified with micronutrients and of an adequate macro- and micronutrient composition is one approach to help meet nutritional requirements during the vulnerable period of 6-24 mo.  相似文献

BACKGROUND: Information is needed to design studies of the effects of complementary feeding regimens on children's intakes of complementary foods (CFs) and breast milk. OBJECTIVE: We evaluated the effects of varied energy density of CFs on the time until stabilization of dietary intakes and on total daily energy intakes (EIs) and breast-milk intakes. DESIGN: CFs with low [0.4 kcal/g (LD)] and high [1.5 kcal/g (HD)] energy density were fed 3 times/d to 10 children (aged 9-18 mo) during 2 randomly assigned sequences of three 8-d diet periods (HD-LD-HD or LD-HD-LD) along with ad libitum breastfeeding. CF and breast-milk intakes were measured. RESULTS: Intakes of the HD diet and breast milk did not vary by day of period, but intake of the LD diet increased progressively. During days 5-7 of the last 2 diet periods in each sequence, more of the LD than of the HD diet was consumed (752 +/- 252 and 439 +/- 111 g/d, respectively; P < 0.001), but EIs from CFs were greater with the HD diet. Breast-milk consumption was slightly less (192 +/- 115 and 234 +/- 121 g/d, respectively; P = 0.03) but total daily EI was greater (774 +/- 175 and 441 +/- 85 kcal/d, respectively; P < 0.001) during the HD than during the LD diet period. CONCLUSIONS: New information on the effects of newly introduced diets on daily intakes of these diets and of breast milk can be used to design future studies. Total daily EIs were greater with the HD diet despite its negative effects on breast-milk intakes.  相似文献

BACKGROUND: Malnutrition in late infancy in developing countries may result from poor-quality complementary foods that displace breast milk. OBJECTIVE: The objective of the study was to assess the effects of fortified complementary blends of different energy densities on growth, hemoglobin concentrations, and breast milk intake of 9-mo-old Zambian infants. DESIGN: Infants were randomly assigned at 6 mo of age to receive for 3 mo a fortified blend of maize, beans, bambaranuts, and groundnuts [Chilenje Baby Mix (CBM); energy density: 68 kcal/100 g; n = 37] or a similar blend with alpha-amylase (CBMA; energy density: 106 kcal/100 g; n = 44). Cross-sectional data were obtained at 9 mo for a control group of infants (n = 69) not given the diets. Breast milk intake was measured by using the dose-to-the-mother deuterium dilution technique. RESULTS: No differences in weight or length z scores, all of which were within normal ranges, were seen between groups at 9 mo. Percentage fat mass was significantly (P = 0.01) greater in the infants in both the CBM (23.2 +/- 2.7%) and CBMA (23.4 +/- 2.5%) groups than in the control group (21.6 +/- 2.6%). Hemoglobin concentrations were significantly (P = 0.03) greater in both intervention groups (CBM group: 104 +/- 12 g/L: CBMA group: 103 +/- 12 g/L) than in the control group (98 +/- 14 g/L). Breast milk intake was not significantly (P = 0.87) different between groups (CBM group: 614 +/- 271 g/d; CBMA group: 635 +/- 193 g/d; control group: 653 +/- 221 g/d). CONCLUSIONS: The study foods improved hemoglobin concentrations without reducing breast milk intake and may be used to improve the nutritional status of infants in developing countries.  相似文献

OBJECTIVE: To understand the relative contributions of breast milk and the weaning diet to overall nutrient intake, with a view to designing and implementing appropriate programmes to improve complementary feeding in developing countries. METHODS: Complementary food intake was measured in a sample of 250 toddlers (mean baseline age: 13.9 +/- 2.4 months) using 24-h dietary recall interviews administered once every 3 weeks over a 6-month period. Breast-milk intake over a 24-h period was measured using the test-weighing method in a subsample of 50 children. Regression effects of age and sex on observed milk intakes were estimated and imputed to the whole sample to estimate mean intake over the observation period. Total energy and nutrient intakes were evaluated for adequacy with reference to published estimates of toddler requirements. FINDINGS: Total energy intake (1029 kcal/day) was adequate, with breast milk supplying an average of 328 kcal/day (32%), but vitamin A, riboflavin, calcium, iron and zinc intakes were below current estimates of required intakes. Observed limitations in nutrient intake were consistent with the finding that almost half of the toddlers were stunted. The prevalence of wasting was 6% at baseline and 4% at final assessment. Although food consumption increased when breastfeeding stopped, it could not fully compensate for the fat and vitamin A previously supplied by breast milk. CONCLUSIONS: The nutritional role of mother's milk in the second year is inversely related to the adequacy of the complementary diet. In this study, breast milk was an irreplaceable source of fat and vitamin A. When the weaning diet is inadequate for key nutrients because of low intake or poor bioavailability, breast milk assumes greater nutritional significance in the second year of life but does not guarantee adequate nutrient intakes.  相似文献

OBJECTIVES: Chronic low-limb ulcers and pressure ulcers are a serious and costly issue. Malnutrition is a risk factor. Searching for intervention strategies in elderly patients referred for surgical closure of their ulcers, the trial aimed at investigating the micronutrient status, determining the food intake of such patients, and the role of oral liquid supplements. METHODS: Observational cohort study in 9 patients, starting 5 days prior to surgery until day 10 after surgery. Variables: body mass index (BMI), food intake assessed using standardized meals (energy target 25 kcal/kg/day). Oral liquid supplements were provided between meals. Laboratory: blood count, plasma proteins, antioxidant status, vitamins, Fe, Se, and Zn. RESULTS: The patients were aged 71+/-10 y (mean+/-SD), with a BMI of 23.3+/-3.3. Baseline blood samples showed anemia and strong inflammation in 4 patients: albumin, retinol, and selenium were low; iron and zinc were very low. Food intake was largely variable and covered only about 76% (31-95%) of energy requirements. Breakfast provided 225+/-110, lunch 570+/-215, and dinner 405+/-150 kcal. Supplements were willingly consumed covering 35+/-12% of energy target. While vitamin supply was adequate, selenium and zinc requirements were not met. CONCLUSIONS: Most patients with chronic skin ulcers suffered micronutrient status alterations, and borderline malnutrition. Meals did not cover energy requirements, while oral supplements covered basic micronutrient requirements and compensated for insufficient oral energy and protein intakes, justifying their use in hospitalized elderly patients.  相似文献

BACKGROUND: Iron bioavailability from traditional complementary foods based on cereals and legumes can be expected to be low unless ascorbic acid-rich foods are incorporated into the diet. OBJECTIVE: We evaluated human milk as a source of ascorbic acid for enhancing iron bioavailability from khichuri, a complementary food based on rice and lentils. DESIGN: Erythrocyte incorporation of stable iron isotopes 14 d after administration was used as a proxy for iron bioavailability. Children aged 8-18 mo (n = 31) were breastfed (32-90 mg ascorbic acid/kg human milk) immediately after intake of 4 servings of khichuri labeled with (57)Fe (test meal B) and were offered water after intake of 4 servings of khichuri labeled with (58)Fe (test meal A). Test meals were fed twice daily during 4 d in the order of AABBAABB or BBAABBAA. RESULTS: The mean intakes of human milk and ascorbic acid were 274 g (range: 60-444 g) and 14 mg (range: 4-28 mg, respectively). The mean molar ratio of ascorbic acid to iron was 2.3 (range: 0.7-4.6). The geometric mean iron bioavailability from khichuri fed with or without human milk was 6.2% and 6.5%, respectively (P = 0.76, paired Student's t test). CONCLUSIONS: Although human milk contributed significant quantities of ascorbic acid, no significant difference in iron bioavailability was found between khichuri consumed with water and that consumed with human milk. These results indicate either that the molar ratio of ascorbic acid to iron was not sufficiently high to overcome the inhibitory effect of phytic acid in khichuri (30 mg/serving) or that components of human milk modified the influence of ascorbic acid on iron bioavailability.  相似文献

BACKGROUND: Twenty-four-hour dietary recalls have been used in large surveys of infant and toddler energy intake, but the accuracy of the method for young children is not well documented. OBJECTIVE: We aimed to determine the accuracy of infant and toddler energy intakes by a single, telephone-administered, multiple-pass 24-h recall as compared with 3-d weighed food records. DESIGN: A within-subjects design was used in which a 24-h recall and 3-d weighed food records were completed within 2 wk by 157 mothers (56 non-Hispanic white, 51 non-Hispanic black, and 50 Hispanic) of 7-11-mo-old infants or 12-24-mo-old toddlers. Child and caregiver anthropometrics, child eating patterns, and caregiver demographics and social desirability were evaluated as correlates of reporting bias. RESULTS: Intakes based on 3-d weighed food records were within 5% of estimated energy requirements. Compared with the 3-d weighed food records, the 24-h recall overestimated energy intake by 13% among infants (740 +/- 154 and 833 +/- 255 kcal, respectively) and by 29% among toddlers (885 +/- 197 and 1140 +/- 299 kcal, respectively). Eating patterns (ie, frequency and location) did not differ appreciably between methods. Macronutrient and micronutrient intakes were higher by 24-h recall than by 3-d weighed food record. Dairy and grains contributed the most energy to the diet and accounted for 74% and 54% of the overestimation seen in infants and toddlers, respectively. Greater overestimation was associated with a greater number of food items reported by the caregiver and lower child weight-for-length z scores. CONCLUSIONS: The use of a single, telephone-administered, multiple-pass 24-h recall may significantly overestimate infant or toddler energy and nutrient intakes because of portion size estimation errors.  相似文献

OBJECTIVE: To investigate the effect of energy density and food volume intakes in one meal (lunch-time) on food and energy intakes in the subsequent meal (tea-time). DESIGN: During lunch, two meals with different energy densities (1.26 and 0.69 kcal/g) were offered to preschool children using normal foods and maintaining a similar energy, carbohydrate, and fat intakes. In the subsequent meal a varied type of high acceptability foods were served in higher amounts than those that children usually consume. SETTING: A day care center where the children were fed during lunch-time and tea-time. SUBJECTS: Two hundred and thirty-four normal preschool children, 108 males and 126 females, according to the weight for height index using the NCHS standards. METHODS: Chemical analysis of the meals served using the AOAC methods and determination of food and energy intakes by differential weighing of the foods. RESULTS: The preschool children had a similar energy intake at lunch but a significantly higher food intake when they consumed the meal with the lower energy density (313 vs. 290.7 kcal) (P = 0.001). There were no differences in the food intakes at the subsequent meal times. CONCLUSIONS: The results of this present work demonstrate that under the conditions of the study, there is an inverse relationship between the energy density of the meals consumed at the first meal-time and the energy intakes at the subsequent meal in normal preschool children; and a direct relationship with the short-term satiety. It is possible that differences in satiety reflect, in part, effects from the characteristics of the normal food used in the dietary treatments. These conclusions suggest that future research must be carried out in order to investigate the separate effects of food and the dietary variables commonly used in the studies of food and energy regulations in humans.  相似文献

BACKGROUND: Strategies need to be developed to reduce preschool children's energy intake. OBJECTIVE: To test the effect of reducing the energy density of an entrée on children's ad libitum energy intake. SUBJECTS: Subjects were 2- to 5-year-old children (37 boys and 40 girls) in a university day-care facility. INTERVENTION: In this within-subjects crossover study, children were served a test lunch once per week for 6 weeks. Two versions of a macaroni and cheese entrée were formulated to differ in energy density while maintaining similar palatability. Each version was served to children three times. The higher-energy-density entrée had 2.0 kcal/g and the other entrée was 30% lower in energy density. Lunch, consumed ad libitum, also included broccoli, applesauce, and milk. MAIN OUTCOME MEASURES: Food intake and energy intake were measured. STATISTICAL ANALYSES: A mixed linear model tested effect of energy density of the entrée on food intake and energy intake. Results are reported as mean+/-standard error. RESULTS: Decreasing the energy density of the entrée by 30% significantly (P<0.0001) reduced children's energy intake from the entrée by 25% (72.3+/-8.3 kcal) and total lunch energy intake by 18% (71.8+/-7.9 kcal). Children consumed significantly more of the lower-energy-density entrée (10.1+/-4.2 g; P<0.05). Children's sex-specific body mass index-for-age percentiles did not affect the relationship between energy density of the entrée and children's intakes. CONCLUSIONS: Decreasing the energy density of a lunch entrée resulted in a reduction in children's energy intake from the entrée and from the total meal. Reducing the energy density of foods may be an effective strategy to moderate children's energy intake.  相似文献

Consumption of food and nutrients by infants in Huascar (Lima), Peru   总被引:2,自引:0,他引:2  
Consumption of breast milk, liquids, and foods by 131 poor Peruvian infants was measured on 1661 child-days of observation during their first year of life. Breast-milk intake was estimated by 12-h test-weighing; macronutrients were analyzed in samples of milk. Other foods and liquids were weighed at preparation and consumption; nutrient contents were estimated from food composition tables. Mean energy intakes increased with age but declined from 95% to 78% of recommended amounts during the year. Mean protein intakes were generally above recommended amounts but more than one-third of infants received less than 80% of the suggested safe intakes in the second (6-mo) semester. Breast milk was the major source of energy and protein during the first semester. Breast milk and cow milk together contributed more than half the energy and protein during the second 6 mo, when cereals were also an important source of energy and protein. Mean intakes of calcium, thiamin, and ascorbic acid were less than recommended at some ages but mean intakes of other selected micronutrients exceeded recommendations.  相似文献

Objective To evaluate the energy and nutrient intake of free-living men and women who choose foods consistent with different fat-reduction strategies.Design For each year of the Continuing Survey of Food Intake by Individuals from 1989 through 1991, food codes were used to sort respondents by type of milk; type of meats; and type of cheese, yogurt, salad dressing, cake, and pudding (ie, full-fat or fat-modified products) consumed.Subjects A nationally representative sample of 3,313 men and 3,763 women who completed 3-day intake records and consumed either a reduced-fat or full-fat food from at least 1 of the 3 fat-reduction strategy categories.Statistical analysis performed Analysis of variance with the Scheffé test was used to analyze differences in energy and nutrient intake between exclusive users, mixed users, and nonusers of each strategy or combined strategies.Results Regardless of fat-reduction strategy, men and women who used them reported significantly lower intakes of total fat (up to 18 g lower), saturated fat (up to 12 g lower), cholesterol (up to 75 ing lower) and energy compared with nonusers. Exclusive users of single strategies met or approached recommendations of the National Cholesterol Education Program for total fat, saturated fat, and cholesterol intake; micronutrient intake varied depending on the strategy used. Skim milk users had the most favorable micronutrient intake, whereas lean meat users reported inadequate intake of zinc (men 6396 and women 59% of the Recommended Dietary Allowances [RDAs]) and female users of fat-modified products reported inadequate intakes of vitamin E (64% of RDA) and zinc (65% of RDA). Multiple-strategy users achieved National Cholesterol Education Program goals and reported adequate micronutrient intakes and significantly lower energy intake. Mixed users of fat-modified products compared with nonusers of any fat-modified products had adequate micronutrient intake and lower intakes of total fat (32% vs 36% of energy for men and 32% vs 35% of energy for women) and saturated fat (11% vs 13% of energy for men and 11% vs 12% of energy for women). In addition, nonusers of any fat-modified strategy had the highest cholesterol and energy intake and the lowest intake of. many micrbnutrients.Applications A variety of fat-reduction strategies can be implemented to reduce energy, total fat, saturated fat, and cholesterol intake. Some of the strategies were associated with an inadequate micronutrient intake, so additional dietary guidance is needed to ensure that all nutrient requirements are met. Furthermore, people who do not use any fat-reduction strategy or those who exclusively use lean meats or fat-modified products would benefit from understanding how to balance their food choices.

Clinical trials were conducted to measure the effect of dietary energy on total daily energy intakes by nine hospitalized young children recovering from protein-energy malnutrition. Semi-solid mixed diets containing either 50 or 100 kcal/100 g were offered at fixed intervals five times per day until the children refused further intake. Each diet was offered for seven consecutive days in alternate order. The mean +/- SD amount consumed with the low-density (LD) diet was significantly greater than with the high-density (HD) diet (220 +/- 35 vs 148 +/- 21 g/kg/d, P less than 0.001), but the amount of energy consumed with the HD diet was significantly greater than with the LD diet (148 +/- 21 vs 110 +/- 18 kcal/kg/d, P less than 0.001). There were no differences in total daily intake by day of diet period with the HD diet, but the intakes increased during the first 2-4 days with the LD diet. The maximum intakes at a single meal averaged between 40 and 66 g/kg/d for individual children receiving the LD diet, and were negatively related to the children's lengths and weight-for-length Z scores. We conclude that dietary energy density limited the amount of energy consumed from LD weaning diets offered at fixed frequencies, presumably because the volume of intake required to satisfy the children's energy needs exceeded their gastric capacity.  相似文献

OBJECTIVES: The main purpose of this study was to determine the anthropometric indications and nutritional intake of pregnant and lactating women in the Vaal Triangle (n = 431). DESIGN AND METHODS: A validated quantitative food frequency questionnaire was used in this study. Trained fieldworkers conducted interviews with the help of food models to estimate portion sizes. The anthropometric measurements included weight, height and body mass index (BMI). Blood samples were collected for determining iron status parameters. RESULTS: The 10 items consumed most frequently by pregnant women were, in descending order: fresh milk; tea; coffee; cold drinks; maize meal; fruit juice; bread; magou (non-alcoholic fermented maize drink); rice and sugar. For lactating women, the results were: fresh milk; tea; coffee; maize meal; cold drinks; magou; bread; yoghurt; rice and sugar. Daily intakes (mean +/- SD) for pregnant women were 8425.71 +/- 2279 kJ, 73.18 +/- 23 g protein, 62.29 +/- 23.7 g fat, 292.45 +/- 72.2 g carbohydrate and 9.74 +/- 3.8 mg iron. For lactating women, the intakes were 8511.94 +/- 2047 kJ, 76.24 +/- 25 g protein, 61.95 +/- 22.3 g fat, 294.37 +/- 64.2 g carbohydrate and 10.50 +/- 4.0 mg iron. The results of this study showed that most of the women (98%) resided in towns and 79.3% were unemployed. The majority of the sample population was overweight or obese (BMI> or = 25). CONCLUSIONS: The diets of the subjects consisted primarily of plant-based foods. Animal foods were scarce except for milk. Most of the items consumed were low in iron. IMPLICATIONS: Iron deficiency is partly induced by plant-based diets containing low levels of poorly bio-available iron. An assessment of dietary intake is required to aid in the development of relevant dietary guidelines for the sample population.  相似文献

The objective of this work was to quantify the impact of the voluntary fortification of foods on dietary intakes of vitamins and minerals of Irish adults. Foods that were voluntarily fortified were identified and pre- and post-fortification levels of micronutrients were determined from data supplied by manufacturers and food composition tables. Using food consumption data in 1379 adults aged 18-64 years, estimated using a 7-d food diary during the North/South Ireland Food Consumption Survey, intakes of micronutrients were determined, both including and excluding the fortification component in foods. Of approximately 3000 foods recorded as consumed, 1.9 % were fortified, mainly breakfast cereals and beverages. Median micronutrient content of fortified foods (FF) ranged from 18-33 % EC RDA per typical serving. Among consumers (65 % of men, 68 % of women), FF contributed, on average, 3.9 % (men) and 5.0 % (women) to mean daily intake (MDI) of energy. Relative to their contribution to MDI of energy, FF contribute a greater % MDI for Fe (men 16, women 19), folate (men 18, women 21), vitamins B1 (men 14, women 16), B2 (men 16, women 18), B6 (men 12, women 15), D (men 5, women 11), B12 (men 5, women 7) and niacin (men 10, women 12). Fortification significantly improved the adequacy of intake of some micronutrients, particularly of riboflavin, folate, vitamin D and Fe in women and did not contribute to an increased risk of adverse effects from excessive intake of any micronutrient.  相似文献

In a WHO-coordinated, mother-to-child HIV transmission (MTCT) prevention trial in Burkina Faso, HIV-1-infected mothers were advised to either stop breast-feeding by 6 mo or totally avoid it. Participants were provided with cereal-based, infant fortified mix (IFM) from 6 to 12 mo postpartum along with infant feeding counseling. Our objective was to describe nonbreast-fed infants' food consumption and adequacy of nutrient intake. A 1-d weighed food record and one 24-h dietary recall were performed in 68 nonbreast-fed, non-HIV-infected 6- to 11-mo-old infants. Mean food energy density and feeding frequency were satisfactory in 6-8 mo olds [0.8 ± 0.2 kcal/g (3.3 ± 0.9 kJ/g) and 7.2 ± 1.6 times/d] and in 9-11 mo olds [0.9 ± 0.2 kcal/g (3.6 ± 0.8 kJ/g) and 7.7 ± 2.1 times/d]. Median energy intake was 523 kcal [range: 82-1053 (2187 kJ, range: 345-4401)] in 6-8- and 811 kcal [range: 34-1543 (3392 kJ, range: 144-6452)] in 9-11-mo-old infants, respectively. Approximately 75% of their energy intake was provided by subsidized foods (milk that mothers obtained from support networks and IFM). One-half of the infants had intakes < 80 kcal/kg (<334 kJ/kg) on the day of the survey, mainly because IFM and milk were consumed in amounts that were too low. Thus, coverage of energy needs required a diet with sufficient amounts of both IFM and milk in these vulnerable infants. These findings argue for the development of adequate, sustainable infant fortified foods and their rapid integration into MTCT prevention services. They also lend support to the recent revision of WHO infant feeding guidance for future MTCT prevention programming that recommends breast-feeding up to 12 mo postpartum (under cover of antiretroviral prophylaxis) as the safest feeding option for infants of HIV-infected mothers.  相似文献

This study aimed to elucidate gender differences in dietary intake of rural Bangladeshi adults. A food frequency questionnaire (FFQ) survey using 15 food/dish items, together with anthropometric measurements, was conducted for 230 adults and adolescents (95 males and 135 females). To estimate the portion sizes of these foods/dishes, the samples consumed by 25 subjects were weighed. The FFQ revealed that rice was eaten two to three times (or more) per day by 98% of the subjects, providing nearly 60% of energy for both sexes. Puri (fried bread), meats, eggs, pulses, milk, fresh vegetables, fruits, tea with milk and sugar, and soft drinks were consumed more frequently by males. Males' larger portion sizes of rice, fish dish, potato dish, and vegetable dish resulted in larger daily energy intake per body weight in males (235 +/- 41 kJ/kg) than in females (161 +/- 28 kJ/kg). Despite males' larger energy intake, the proportion of chronically energy deficient persons (<18.5 kg/m2 in body mass index) was similar between males (35.8%) and females (37.8%), attributing to males' larger energy expenditure. Females' less-frequent consumption of nutritious foods and smaller energy intake were considered vulnerable to micronutrient deficiency.  相似文献

BACKGROUND: The optimal age at which to introduce complementary foods is a topic of considerable debate. OBJECTIVE: This study was designed to evaluate this issue in a nutritionally vulnerable population in Honduras. DESIGN: Mothers of low-birth-weight (1500-2500 g) term (ie, small-for-gestational-age) infants were recruited in the hospital and assisted with exclusive breast-feeding during the first 4 mo. At 4 mo, mothers were randomly assigned to either continue exclusive breast-feeding to 6 mo (EBF; n = 59) or to feed complementary solid foods (jarred rice cereal, chicken, and fruit and vegetables) twice daily from 4 to 6 mo while continuing to breast-feed at their initial frequency (SF; n = 60). At 4 and 6 mo, breast milk and total energy intake were measured for a nonrandom subsample (those who could stay overnight in a central unit: 32 EBF and 31 SF). RESULTS: At 4 mo, breast milk intake in the subsample was not significantly different between groups (EBF: 729 +/- 135 g/d; SF: 683 +/- 151 g/d: P >0.2); from 4 to 6 mo it increased (by 28 g/d) in the EBF group but decreased (by 39 g/d) in the SF group (P < 0.005). Nonetheless, total energy intake (including solid foods) increased more from 4 to 6 mo in the SF than in the EBF group. However, there were no significant differences between groups in weight or length gain during the intervention or subsequently (6-12 mo). CONCLUSION: There was no growth advantage of complementary feeding of small-for-gestational-age, breast-fed infants between 4 and 6 mo of age.  相似文献
