Food Groups Associated with a Composite Measure of Probability of Adequate Intake of 11 Micronutrients in the Diets of Women in Urban Mali

The prevalence of micronutrient deficiency is high among women of reproductive age living in urban Mali. Despite this, there are little data on the dietary intake of micronutrients among women of reproductive age in Mali. This research tested the relationship between the quantity of intake of 21 possible food groups and estimated usual micronutrient (folate, vitamin B-12, calcium, riboflavin, niacin, vitamin A, iron, thiamin, vitamin B-6, vitamin C, and zinc) intakes and a composite measure of adequacy of 11 micronutrients [mean probability of adequacy (MPA)] based on the individual probability of adequacy (PA) for the 11 micronutrients. Food group and micronutrient intakes were calculated from 24-h recall data in an urban sample of Malian women. PA was lowest for folate, vitamin B-12, calcium, and riboflavin. The overall MPA for the composite measure of 11 micronutrients was 0.47 +/- 0.18. Grams of intake from the nuts/seeds, milk/yogurt, vitamin A-rich dark green leafy vegetables (DGLV), and vitamin C-rich vegetables food groups were correlated (Spearman's rho = 0.20-0.36; P 0.5, respectively. These findings can be used to further the development of indicators of dietary diversity and to improve micronutrient intakes of women of reproductive age. J. Nutr. 140: 2070S-2078S, 2010

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 650kcalday-1 (126gday-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

Dietary Diversity Is Positively Associated with Deviation from Expected Height in Rural Nepal.

BACKGROUND: Recent research has highlighted the need for additional studies on the nutrition input required to stabilize growth. OBJECTIVE: Our objective was to examine the association between dietary diversity and conditional growth in children aged 0-89 mo. METHODS: We analyzed cohort data from 529 mothers and children living in a remote and food-insecure region in the mountains of Nepal. Children were aged 0-59 mo at baseline and were followed up after 9 and 29 mo. Conditional growth was calculated as the deviation from the expected height-for-age difference (HAD) trajectory based on previous measures of HAD and the pattern of growth in the population. Dietary diversity was assessed with the use of a count of the foods consumed from 7 food groups in the previous 7 d. The association between dietary diversity and conditional growth during the 2 follow-up periods (of 9 and 20 mo, respectively) was estimated with the use of ordinary least-squares regressions. RESULTS: Prevalence of stunting and absolute height deficits was very high and increased over the course of the study. At the last measurement (age range 29-89 mo), 76.5% were stunted and the mean ± SD HAD was -11.7 ± 4.6 cm. Dietary diversity was associated positively with conditional growth in the later (May 2012-December 2013) but not the earlier (July 2011-May 2012) growth period. Children's ages ranged from 0 to 59 mo in July 2011, 9 to 69 mo in May 2012, and 29 to 89 mo in December 2013. After adjustment, increasing the dietary diversity by one food group was associated with a 0.09 cm (95% CI: 0.00, 0.17 cm) increase in conditional growth in the second growth period. CONCLUSIONS: Increasing dietary diversity for children reduces the risk of stunting and improves growth after growth faltering. Future efforts should be directed at enabling families in food-insecure areas to feed their children a more diverse diet

Evidence for perinatal and child health care guidelines in crisis settings: can Cochrane help?

<p>Abstract</p> <p>Background</p> <p>It is important that healthcare provided in crisis settings is based on the best available research evidence. We reviewed guidelines for child and perinatal health care in crisis situations to determine whether they were based on research evidence, whether Cochrane systematic reviews were available in the clinical areas addressed by these guidelines and whether summaries of these reviews were provided in Evidence Aid.</p> <p>Methods</p> <p>Broad internet searches were undertaken to identify relevant guidelines. Guidelines were appraised using AGREE and the clinical areas that were relevant to perinatal or child health were extracted. We searched The Cochrane Database of Systematic Reviews to identify potentially relevant reviews. For each review we determined how many trials were included, and how many were conducted in resource-limited settings.</p> <p>Results</p> <p>Six guidelines met selection criteria. None of the included guidelines were clearly based on research evidence. 198 Cochrane reviews were potentially relevant to the guidelines. These reviews predominantly addressed nutrient supplementation, breastfeeding, malaria, maternal hypertension, premature labour and prevention of HIV transmission. Most reviews included studies from developing settings. However for large portions of the guidelines, particularly health services delivery, there were no relevant reviews. Only 18 (9.1%) reviews have summaries in Evidence Aid.</p> <p>Conclusions</p> <p>We did not identify any evidence-based guidelines for perinatal and child health care in disaster settings. We found many Cochrane reviews that could contribute to the evidence-base supporting future guidelines. However there are important issues to be addressed in terms of the relevance of the available reviews and increasing the number of reviews addressing health care delivery.</p

Dietary diversity at 6 months of age is associated with subsequent growth and mediates the effect of maternal education on infant growth in urban Zambia.

BACKGROUND: Although numerous cross-sectional studies have shown an association between WHO infant and young child feeding (IYCF) indicators and child anthropometric measures, limited longitudinal evidence exists linking these indicators with subsequent growth. OBJECTIVES: The purpose of this study was to investigate whether meeting WHO IYCF indicators at 6 and 12 mo of age was associated with growth to 18 mo of age and if dietary diversity mediated the relation between household wealth, maternal education, and child growth. METHODS: We used longitudinal data on 811 infants in the CIGNIS (Chilenje Infant Growth, Nutrition, Infection Study), a randomized controlled trial comparing the effect of micronutrient-fortified porridges on infant growth in Lusaka, Zambia. Twenty-four-h diet recalls were conducted at 6 and 12 mo of age, and length and weight measurements at ages 6 and 18 mo were used to produce height-for-age Z-scores (HAZs) and weight-for-height Z-scores (WHZs). Information on household assets was used to generate a household wealth index, and level of maternal education was collected. RESULTS: In fully adjusted analyses, iron-rich food intake at 6 mo and greater household wealth and maternal education were positively associated with HAZ at 18 mo (all P ≤ 0.016). Iron-rich food intake at 6 and 12 mo, achieving a "minimum acceptable diet" at 12 mo, and higher maternal education were associated with greater WHZ at 18 mo (all P ≤ 0.044). Dietary diversity at 6 mo of age was positively associated with both HAZ and WHZ at 18 mo (both P ≤ 0.001) and mediated 13.4% and 25.9% of the total effect of maternal education on HAZ and WHZ, respectively, at 18 mo. CONCLUSIONS: Our findings indicate that IYCF programs should be targeted toward the early period of complementary food introduction and that policies aimed at increasing formal maternal education may benefit child growth through improved feeding practices.
