Impact of lipid-based nutrient supplementation (LNS) on children's diet adequacy in Western Uganda

Effect of Oral Nutritional Supplementation on Adequacy of Nutrient Intake among Picky-Eating Children at Nutritional Risk in India: A Randomized Double Blind Clinical Trial

Nutrient inadequacies among picky-eaters have adverse effects on growth and development. Oral nutritional supplements (ONS) along with dietary counseling (DC), rather than DC alone as reported in our earlier publication, promoted growth among picky-eating Indian children aged from >24 m to ≤48 m with weight-for-height percentiles lying between the 5th and 25th (based on WHO Growth Standards) over 90 days. This paper presents the contribution of ONS to nutrient adequacy, dietary diversity, and food consumption patterns in children (N = 321). Weight, height, and dietary intakes, using 24-h food recalls, were measured at baseline (Day 1) and at Days 7, 30, 60, and 90. Nutrient adequacy, dietary diversity score (DDS), and food intake adequacy were calculated in both the supplementation groups (ONS1 + DC and ONS2 + DC; n = 107 in each group) and the control group (DC-only; n = 107). Supplements increased nutrient adequacy in both of the ONS + DC groups relative to control (p < 0.05). The proportions of children with adequate nutrient intakes increased significantly at Day 90 in the supplemented groups as compared to in the control group (p < 0.05), especially for total fat, calcium, vitamin A, vitamin C, and thiamin. Although no significant differences were observed in DDS in any of the groups, the percentage of children consuming ≥4 food groups in a day had increased in all the groups. Consumption of fruit and vegetables and cereals had increased significantly from baseline to Day 90. ONS along with dietary counseling was found to have improved nutritional adequacy without interfering with the normal food consumption patterns of picky-eating children at nutritional risk.

A food‐based approach could improve dietary adequacy for 12–23‐month‐old Eastern Ugandan children

Little is known about dietary adequacy, for young Ugandan children, or context‐specific food choices to improve it. This study estimated the percentage of breastfed 12–23‐month‐old rural Eastern Ugandan children (n = 114) at risk of inadequate intakes of 12 nutrients; and identified realistic food choices for improving it. In this cross‐sectional survey, dietary (weighed food records), anthropometric and socioeconomic data were collected. The percentages of children at risk of inadequate nutrient intakes were estimated, assuming 541 g/day of breast milk was consumed. The median nutrient densities of their complementary feeding diets were also compared with desired levels. Linear programming analyses were used to identify ‘problem nutrients’ (where requirements will be difficult to meet given dietary practices) and model food choices to improve dietary adequacy. Overall, 21.2% of children were stunted and 3.8% were wasted. A high percentage (>45%) of children were at risk of inadequate intakes, for nine of the 12 nutrients assessed, and dietary nutrient densities were below desired levels for seven of the 12 nutrients. Iron, calcium, thiamine and niacin were ‘problem nutrients’. Through careful selection of foods, modelling indicates that population level dietary adequacy can be achieved for eight of the 12 nutrients modelled. These choices include cows' milk, legumes, green leafy vegetables, sweet potatoes and fruits. Overall results suggest these high percentages of children at risk of inadequate nutrient intakes can be reduced through behaviour change interventions, although additional interventions may be required to ensure population‐level dietary adequacy for iron, thiamine and niacin.

Dietary adequacy, for breastfed 12–23‐month‐old rural Eastern Ugandan children, is poor with over 45% of children at risk of inadequate intakes of nine micronutrients.

Inadequate intakes of micronutrients likely contribute to growth faltering in this population where 21% of children are stunted but less than 4% are wasted.

Dietary adequacy can be improved through careful selection of nutrient‐dense foods, including cows' milk, legumes, green leafy vegetables, sweet potatoes, and fruits.

A food‐based approach alone, however, will not reduce the percentage of children at risk of inadequate intakes to low levels, for iron, thiamine and perhaps niacin, indicating alternative interventions are required.

Fortified Balanced Energy-Protein Supplements Increase Nutrient Adequacy without Displacing Food Intake in Pregnant Women in Rural Burkina Faso

BACKGROUND

In many low- and middle-income countries, the prevalence of energy and nutrient deficiencies is high among pregnant women. Balanced energy-protein (BEP) supplements are a promising strategy to cover nutritional requirements during pregnancy and improve birth outcomes. However, the displacement of nutrient-dense foods by BEP might attenuate the efficacy of supplementation.

OBJECTIVE

This cross-sectional study of participants in a randomized controlled trial evaluated the difference in energy and macro- and micronutrient intakes, food groups, and nutrient adequacy between a control and intervention group receiving either a daily iron-folic acid (IFA) tablet or IFA and BEP supplement during pregnancy, respectively.

METHODS

We collected a single multiple-pass 24-h recall from 470 pregnant women from the MIcronutriments pour la SAnté de la Mère et de l'Enfant (MISAME) III study that investigates the efficacy of BEP supplementation on birth outcomes and infant growth. Dietary intake (median and IQR) and nutrient adequacy were assessed using individual recipes and preparation methods of mixed dishes for each participant. Linear regression models were fitted to compare energy and nutrient intakes.

RESULTS

Dietary energy, and macro- and micronutrient intakes were significantly higher among women in the intervention group when including BEP [2329 kcal/d (1855, 3008 kcal/d) compared with 1942 kcal/d (1575, 2405 kcal/d) in the control group (all P < 0.001)]. The difference in median energy intake (448 kcal/d; 95% CI: 291, 605 kcal/d) was approximately equivalent to a daily dose of the BEP supplement (393 kcal). Nutrient adequacy ratios for both groups were low for all micronutrients (between 0.02 and 0.66), when excluding BEP (except iron and folic acid, due to standard supplemental doses) from analysis. However, nutrient intakes increased to the Estimated Average Requirement for pregnant women when including BEP supplements.

CONCLUSIONS

BEP supplementation increases energy and macro- and micronutrient intakes among pregnant women and fills nutrient gaps without displacing food intake. This trial was registered at clinicaltrials.gov as NCT03533712 (https://clinicaltrials.gov/ct2/show/NCT03533712).

Impacts of an egg intervention on nutrient adequacy among young Malawian children

Eggs are a rich source of multiple nutrients that support child growth and development. Provision of eggs as a complementary food may improve dietary adequacy among young children at risk for undernutrition. Our objective was to test the impact of an egg intervention on the adequacy of total nutrient intakes and micronutrient density among 6- to 15-month-old Malawian children. Children 6 to 9 months old, living in Mangochi District, Malawi, were randomly assigned to the intervention group (n = 331) receiving an egg per day or a control group (n = 329) consuming their usual diet. Dietary intakes of macronutrients, vitamins and minerals were assessed using 24-h recalls at baseline, 3-month midline and 6-month endline, with repeat recalls in a subsample. Usual nutrient intake and micronutrient density distributions were modelled to estimate group means and prevalence of inadequacy. Group differences at midline and endline were tested using unequal variance t tests with bootstrapped standard errors. The egg intervention resulted in higher intakes of fat and protein and lower intakes of carbohydrates. The egg group had lower prevalence of inadequacy for selenium, vitamin A, riboflavin, vitamin B5 , vitamin B12 and choline. Micronutrient density inadequacy was lower in the egg group for vitamin A and choline at midline and endline, riboflavin at midline and vitamin B5 at endline. Inadequacy of nutrient intakes or density remained highly prevalent in both groups for multiple micronutrients. Though the egg intervention increased intakes of protein and several micronutrients, total intakes and micronutrient density of multiple micronutrients remained far below recommendations.

Fortified blended flour supplements displace plain cereals in feeding of young children

Lipid-based nutritional supplements (LNS) and fortified blended flours (FBF) are widely used to increase the nutrient density of children's diets and improve their health, but their effectiveness could be modified by displacement of other foods. We reanalysed data from a cost-effectiveness trial comparing impacts on anthropometry of three FBFs (Corn Soy Blend Plus [CSB+], Corn Soy Whey Blend [CSWB], SuperCereal Plus [SC+]) and one LNS (Ready-to-use Supplementary Food [RUSF]) among infants aged 7-23 months in Burkina Faso. Using dietary diversity data from a single 24-h recall period (n = 1,591 children, observed once over 18-month study period), we fit logistic regression models to estimate differences in intake of each food group making up the infant and young child minimum dietary diversity score and linear models to test for differences in dietary diversity score among children in each supplement arm. We tested for differences in breastfeeding time using the subsample for which breastfeeding was observed (n = 176). Children who consumed one of the three FBFs had lower odds of consuming household grains, roots and tubers compared with the LNS consumers (odds ratios [ORs] = 0.35-0.47; 95% confidence intervals [CIs]: 0.20-1.05). Consumption of other foods, dietary diversity and breastfeeding did not differ significantly at the 5% significance level. FBFs displaced the household's own cereals more than LNS, with no difference in the child's consumption of other more nutrient-rich family foods. Given limited stomach capacity and feeding time, providing fortified cereals may help improve children's overall diet quality in settings where children would otherwise be fed nutrient-poor root crops or cereal grains.

An Integrated Infant and Young Child Feeding and Small-Quantity Lipid-based Nutrient Supplementation Program Is Associated with Improved Gross Motor and Communication Scores of Children 6-18 Months in the Democratic Republic of Congo

OBJECTIVE

To evaluate the impact of an infant, young child feeding practices-small-quantity lipid nutrient supplements (SQ-LNS) intervention on child development scores in children aged 6-18 months in the Katanga Province, Democratic Republic of Congo (DRC).

STUDY DESIGN

We analyzed data of 2595 children from 2 health zones in a quasi-experimental design with preimplementation and postimplementation surveys to evaluate program impact on child development scores. Standard care was received in the comparison health zone and the intervention health zone received standard care plus enhanced infant, young child feeding practices with a monthly supply of 28 SQ-LNS sachets for up to 1 year. Program exposure and communication and motor domains of the Ages and Stages questionnaire were collected to assess changes in child development scores. A quasi-intent-to-treat and adjusted difference-in-difference analyses were used to quantify impact of the enhanced compared with the standard package.

RESULTS

In adjusted models contrasting endline with baseline, there was a greater relative increase in proportion of children with normal communication (difference-in-difference, +13.7% [95%CI, 7.9-19.6; P < .001] and gross motor scores, +7.4% [95% CI: 1.3-13.5; P < .001]) in the intervention vs comparison health zones. Further, in separate analyses among children of intervention health zone at endline, each additional SQ-LNS distribution was associated with +0.09 (95% CI, 0.03-0.16) z-score unit increase in gross motor scores (P < .01).

CONCLUSIONS

The integrated infant, young child feeding practice-SQ-LNS intervention was positively associated with larger relative improvements in measures of child communication and motor development in the Katanga province of DRC.

Intrahousehold management and use of nutritional supplements during the hunger gap in Maradi region, Niger: a qualitative study

Background

Nutritional supplements are used for preventing and treating childhood malnutrition. While there is a growing body of evidence on product efficacy, less emphasis has been placed on how they are perceived and used at the household level. Here, we report on the intrahousehold management of three different supplements (Ready to Use Supplementary food (RUSF), medium quantity lipid-based nutrient supplements (LNS-MQ) and Super Cereal Plus (SC+)) in the region of Maradi (Niger). The main objective of this study was to describe the use, consumption and perception of the three different nutritional products at the household level.

Methods

The study was conducted in the Madarounfa district in the region of Maradi (February – March 2012). Female caregivers were purposely selected from eligible households and invited to participate. Data were collected through focus group discussion and interviews and were analyzed using thematic content analysis.

Results

In total, 114 caregivers participated. Three major themes were initially identified and included preparation and conservation; consumption and sharing practices as well as perception of impact. The data showed good acceptance at the household level including perceived benefits for the target children, health improvement, prevention of illness and malnutrition. Sharing and gifting at both household and community level were also reported.

Conclusions

Caregivers displayed positive perceptions toward the investigated supplements. Patterns of actual management should be considered in the design, implementation, monitoring and evaluation of future programs.

Systematic Review of Tools and Methods to Measure Appetite in Undernourished Children in the Context of Low- and Middle-Income Countries

Child undernutrition has multifactorial causes, ranging from food insecurity to etiologies refractory to conventional nutritional approaches, such as infections, environmental enteric dysfunction, and other conditions that lead to systemic inflammation. Poor appetite may be an important symptom of these causes and may be a useful marker of an undernourished child's ability to recover. We conducted a systematic review to characterize the methods and tools to measure appetite among children <5 y old in low- and middle-income countries. A systematic search of 8 databases identified 23 eligible studies published since 1995. Thirteen described methods based on direct feeding observation or quantification of nutrient intake from caregiver report, 16 described tools that assessed caregiver perceptions of appetite, and 6 reported assessments in both categories. Four studies that gauged caregiver perceptions assessed multiple appetite domains, whereas 12 assessed 1 domain-often with a single question. Only 6 studies reported validation processes, the most common of which compared an observed test meal with daily energy intake. No studies reported the use of a method or tool that was validated in multiple cultural or linguistic contexts. Although dietary intake measures and observed feeding tests have shown validity in some contexts, they are resource intensive. Subjective caregiver questionnaires may offer a more efficient appetite evaluation method, but they have been evaluated less consistently. A rigorously developed and validated tool to rapidly assess child appetite is needed and could be best addressed by a questionnaire that leverages the multiple domains of appetite. The application of interventions that target causes of undernutrition that are not amenable to food-based interventions in clinical or research contexts could be facilitated by an efficient appetite screening tool to identify appetite-related causes of undernutrition and to monitor children's response to such interventions.

Complementary Food Supplements Increase Dietary Nutrient Adequacy and Do Not Replace Home Food Consumption in Children 6-18 Months Old in a Randomized Controlled Trial in Rural Bangladesh

Background

Inadequate complementary feeding is common in low- and middle-income countries, contributing to growth deficits. Complementary food supplements (CFSs) aim to fill dietary gaps, but few CFS studies have measured nutrient intake. In a community-based, randomized CFS trial in Bangladesh, we previously reported poor dietary diversity in 6-18-mo-old participants.

Objective

We investigated, in a secondary analysis in the same trial, micronutrient intake adequacy in supplemented compared with control-arm children.

Methods

At age 6 mo, children were assigned to 1 y of child-feeding counseling for mothers (control) or counseling plus 1 of 4 CFS formulations. Mothers were administered quantitative past 24-h diet questionnaires for their children at ages 6, 9, 12, 15, and 18 mo. Nutrient intakes were estimated with local recipes and food composition tables assuming average age-specific breastmilk intake. Adequacy was evaluated relative to estimated average requirements or adequate intakes. Multivariate analysis of variance and generalized estimating equation (GEE) regression models estimated the effect of each CFS on nutrient adequacy. GEE models tested dietary predictors of nutrient adequacy in the control arm.

Results

A total of 25,964 dietary modules across 5 interviews were completed. Nutrient adequacy from home foods combined with assumed breastmilk intake was low. Only 5 of 16 micronutrients were adequately consumed by >60% of children at 18 mo of age. Daily CFSs did not affect energy-adjusted micronutrient intake from home foods at any follow-up age (P > 0.05). CFSs increased the mean adequacy ratio for all micronutrients (P < 0.001 at all ages), to ≥1 for 14 of 16 micronutrients at 18 mo. Dietary diversity predicted adequate iron, zinc and calcium intake at 15 mo in unsupplemented controls.

Conclusions

Home foods did not meet the estimated micronutrient needs of 9-18-mo-old children in rural Bangladesh. Daily supplementation with fortified complementary foods filled many micronutrient intake gaps and did not displace home foods. Previously, CFSs were shown to also improve linear growth and reduce stunting in this cohort. Findings support the need for CFSs in similar settings to promote nutritional well being and growth. This trial was registered at clinicaltrials.gov as NCT01562379.

Maternal participation in a nutrition education program in Uganda is associated with improved infant and young child feeding practices and feeding knowledge: a post-program comparison study

Background

Cost-effective approaches to improve feeding practices and to reduce undernutrition are needed in low-income countries. Strategies such as nutritional counseling, food supplements, and cash transfers can substantially reduce undernutrition among food-insecure populations. Lipid-based nutrient supplements (LNS) are an increasingly popular strategy for treating and preventing undernutrition and are often delivered with nutrition education. The post-program effects of participation in a LNS-supported supplemental feeding program on Infant and Young Child Feeding (IYCF) practices and caregiver child feeding knowledge are not well understood. The objective of this study was to understand whether children’s diet quality and caregiver nutrition knowledge was improved after participation in such a program.

Methods

We conducted a post-program comparison group study to compare feeding practices and caregiver nutrition knowledge among mother-child dyads who completed a nutrition education program and a community comparison group in western Uganda. We administered a feeding practices survey and two 24-h dietary recalls to 61 Post-Program (PP) caregivers and children ages 6 to 59 months (mean age = 25.1 months) who participated in a supplemental feeding program (which included growth monitoring, caregiver nutrition education, and LNS) and a Comparison Group (CG) of 61 children and caregivers. PP caregivers were recruited 4 to 8 weeks after program participation ended. We hypothesized that PP caregivers would report better IYCF practices and greater knowledge of key nutrition education messages related to IYCF.

Results

PP children had higher dietary diversity scores (3.0 vs 2.1, p =0.001) than CG children, and were more fed more frequently (3.0 vs 2.1 times per day, p = 0.001). IYCF indicators were higher in the PP group for minimum meal frequency (44.8% vs. 37.9%), minimum dietary diversity (10.3 vs. 3.4%), iron-rich complementary foods (17.2 vs. 20.7%), and minimally acceptable diet (10.3% vs 3.6%), but differences were non-significant. Caregivers in the PP group demonstrated greater knowledge of healthful IYCF practices.

Conclusions

Nutrition education can be effective to improve caregiver feeding practices and children’s dietary diversity and the frequency by which they are fed. A 10-week nutrition education and supplemental feeding program appears to provide some benefit to children in terms of dietary diversity and frequency of meals, and caregiver knowledge of feeding 1 to 2 months after program completion. However, children in this rural Ugandan region have diets that are still largely inadequate, highlighting the need for enhanced interventions and policies to promote diverse and appropriate diets for young children in this region. Future follow-up work in LNS-supported programs is recommended to understand how other similar approaches influence children's diet quality after program completion in other contexts.

Effect of complementary food supplementation on breastfeeding and home diet in rural Bangladeshi children

BACKGROUND

Complementary food supplements (CFSs) can enhance growth where stunting is common, but substitution for the usual diet may reduce observed benefits.

OBJECTIVE

We aimed to characterize dietary diversity from home foods in a CFS efficacy trial and determine whether supplementation reduced breastfeeding frequency or displaced home foods.

DESIGN

In a cluster-randomized controlled trial in rural Bangladesh, children (n = 5499) received, for 1 y starting at age 6 mo, periodic child feeding counseling for mothers (control) or counseling plus 1 of 4 CFSs fed as a daily snack. Breastfeeding status and past 24-h diet were assessed at enrollment and every 3 mo thereafter until 18 mo of age. A 7-food group dietary diversity score (DDS) was calculated from home foods only, and a DDS ≥4 constituted minimum dietary diversity (MDD).

RESULTS

Most children (97%) were breastfed through 18 mo of age, and 24-h breastfeeding frequency did not differ by supplementation group. Child dietary diversity was low; only 51% of children met the MDD by 18 mo. Rice, potatoes, and biscuits (cookies) were the most frequently consumed foods, whereas the legumes, dairy, eggs, and vitamin A-rich fruit and vegetable food groups were each consumed by <50% of children. The odds of meeting the MDD through the consumption of home foods were equal or greater in the supplemented groups compared with the control group at all ages. High socioeconomic status and any maternal education were associated with increased odds of MDD at age 18 mo, whereas child sex and household food security were not associated with MDD.

CONCLUSIONS

In a setting where daily complementary food supplementation improved linear growth, there was no evidence that supplementation displaced breastfeeding or home foods, and the supplementation may have improved dietary diversity. Pathways by which supplementation with fortified foods may enhance dietary diversity, such as an improved appetite and increased body size, need elucidation. This trial was registered at clinicaltrials.gov as NCT01562379.

Impact of lipid-based nutrient supplementation (LNS) on children's diet adequacy in Western Uganda

Lipid-based nutrient supplements (LNS) can help treat undernutrition; however, the dietary adequacy of children supplemented with LNS, and household utilisation patterns are not well understood. We assessed diet adequacy and the quality of complementary foods by conducting a diet assessment of 128 Ugandan children, ages 6-59 months, who participated in a 10-week programme for children with moderate acute malnutrition (MAM, defined as weight-for-age z-score < -2). Caregivers were given a weekly ration of 650 kcal day(-1) (126 g day(-1) ) of a peanut/soy LNS. Two 24-h dietary recalls were administered per child. LNS was offered to 86% of targeted children at least once. Among non-breastfed children, over 90% met their estimated average requirement (EAR) cut-points for all examined nutrients. Over 90% of breastfed children met EAR cut-points for nutrient density for most nutrients, except for zinc where 11.7% met cut-points. A lower proportion of both breastfed and non-breastfed children met adjusted EARs for the specific nutritional needs of MAM. Fewer than 20% of breastfed children met EAR nutrient-density guidelines for MAM for zinc, vitamin C, vitamin A and folate. Underweight status, the presence of a father in the child's home, and higher programme attendance were all associated with greater odds of feeding LNS to targeted children. Children in this community-based supplemental feeding programme who received a locally produced LNS exhibited substantial micronutrient deficiencies given the special dietary needs of this population. These results can help inform programme strategies to improve LNS targeting, and highlight potential nutrient inadequacies for consumers of LNS in community-based settings.
