Defining a Dichotomous Indicator for Population-Level Assessment of Dietary Diversity Among Pregnant Adolescent Girls and Women: A Secondary Analysis of Quantitative 24-h Recalls from Rural Settings in Bangladesh, Burkina Faso, India, and Nepal

BackgroundThe Minimum Dietary Diversity for Women of Reproductive Age (MDD-W) indicator was validated as a proxy of micronutrient adequacy among nonpregnant women in low- and middle-income countries (LMICs). At that time, indeed, there was insufficient data to validate the indicator among pregnant women, who face higher micronutrient requirements. ObjectiveThis study aimed to validate a minimum food group consumption threshold, out of the 10 food groups used to construct MDD-W, to be used as a population-level indicator of higher micronutrient adequacy among pregnant women aged 15–49 y in LMICs. MethodsWe used secondary quantitative 24-h recall data from 6 surveys in 4 LMICs (Bangladesh, Burkina Faso, India, and Nepal, total n = 4909). We computed the 10-food group Women's Dietary Diversity Score (WDDS-10) and calculated the mean probability of adequacy (MPA) of 11 micronutrients. Linear regression models were fitted to assess the associations between WDDS-10 and MPA. Sensitivity, specificity, and proportion of individuals correctly classified were used to assess the performance of MDD-W in predicting an MPA of >0.60. ResultsIn the pooled sample, median values (interquartile range) of WDDS-10 and MPA were 3 (1) and 0.20 (0.34), respectively, whereas the proportion of pregnant women with an MPA of >0.60 was 9.6%. The WDDS-10 was significantly positively associated with MPA in each survey. Although the acceptable food group consumption threshold varied between 4 and 6 food groups across surveys, the threshold of 5 showed the highest performance in the pooled sample with good sensitivity (62%), very good specificity (81%), and percentage of correctly classified individuals (79%). ConclusionsThe WDDS-10 is a good predictor of dietary micronutrient adequacy among pregnant women aged 15–49 y in LMICs. Moreover, the threshold of 5 or more food groups for the MDD-W indicator may be extended to all women of reproductive age, regardless of their physiologic status.

Provision of low-aflatoxin local complementary porridge flour reduced urinary aflatoxin biomarker in children aged 6-18 months in rural Tanzania.

Aflatoxins are toxic secondary metabolites of fungi that colonize staple food crops, such as maize and groundnut, frequently used in complementary feeding. In preparation for a large trial, this pilot study examined if provision of a low-aflatoxin infant porridge flour made from local maize and groundnuts reduced the prevalence of a urinary aflatoxin biomarker in infants. Thirty-six infants aged 6-18 months were included from four villages in Kongwa District, Tanzania. The study was conducted over 12 days with a three-day baseline period and a 10 days where low-AF porridge flour was provided. Porridge intake of infants was assessed using quantitative 24-h recalls by mothers. Household food ingredients used in infant porridge preparation and urine samples were collected on Days 1-3 (baseline) and 10-12 (follow-up). Aflatoxins were measured in household foods, and AFM1 was measured in urine. At baseline and follow-up, 78% and 97%, respectively, of the infants consumed porridge in the previous 24 h, with a median volume of 220 mL (interquartile range[IQR]: 201, 318) and 460 mL (IQR: 430, 563), respectively (p < 0.001). All 47 samples of homemade flour/ingredients were contaminated with AFs (0.3-723 ng/g). The overall prevalence of individuals with detectable urinary AFM1 was reduced by 81%, from 15/36 (42%) at baseline to 3/36 (8%) at follow-up (p = 0.003). Provision of low-aflatoxin porridge flour was acceptable to caregivers and their infants and successfully reduced the prevalence of detectable urinary AFM1 in infants, thus, confirming its potential to be tested in future large-scale health outcomes trial.

A Poultry Value Chain Intervention Promoting Diversified Diets Has Limited Impact on Maternal and Child Diet Adequacy during the Lean Season in a Cluster Randomized Controlled Trial

BackgroundSoutenir l'Exploitation Familiale pour Lancer l’Élevage des Volailles et Valoriser l’Économie Rurale (SELEVER) is a nutrition- and gender-sensitive poultry value chain project designed and implemented by international nongovernmental organization Tanager, which consists of poultry market facilitation and behavior change activities aiming at increasing poultry production and improving diets without free inputs transfer. ObjectivesThe study aimed at assessing the impact of SELEVER on diets of women and children during the lean season. MethodsWithin a cluster randomized controlled trial, 45 communes were assigned to 1 of 3 arms, including 1) SELEVER interventions, 2) SELEVER with an intensive hygiene and sanitation component (SELEVER + WASH), and 3) a control group without intervention. Two rounds of survey were conducted 2 y apart during the lean season. Primary dietary outcomes were the probability of adequacy (PA) of iron, zinc, and vitamin A intakes; mean PA of 11 micronutrients and individual dietary diversity score collected through quantitative 24-h recall in longitudinal samples of women and index children (2–4 y old) in 1054 households; and minimum acceptable diet in the repeated cross-sectional sample of their younger sibling aged 6–23 mo. Impacts were assessed by intention-to-treat ANCOVA. ResultsRelative to control, SELEVER interventions (groups 1 + 2) increased the PA of iron intakes in women by 1.8 percentage points (pp) (P = 0.030). We found no further impact on primary outcomes, although egg consumption increased in index children (+0.73 pp, P = 0.010; +0.69 kcal/d, P = 0.036). Across the 3 groups, we observed negative effects of SELEVER on the PA of zinc intakes in women relative to SELEVER + WASH (–4.1 pp, P = 0.038) and on a variety of secondary dietary outcomes relative to both other groups. The study was registered on the ISCRCTN registry (ISRCTN16686478). ConclusionsInformation-only-based value chain interventions may not have meaningful positive effects on diets of women and children in the lean season in settings with largely inadequate diets. We found suggestive evidence that synergies between intervention components may have introduced heterogeneity in effects on diet.

Deficient Nutrient Intake from Complementary Foods among Infants Aged 6-11 Months in Rural Areas of Yogyakarta.

Nutrition education message that is developed based on linear programming could help arrange complementary feeding recommendations (CFR) using locally available food to improve infants' nutrient adequacy. This study examined deficient nutrients to optimize complementary feeding for infants. Data were collected from the Health District Office of Yogyakarta province that consisted of 91 breastfed infants aged 6-11 mo old. Their dietary intake was assessed by quantitative 24-h recall and data were processed using the software Nutrisurvey, MS Excell, and Optifood. Meat, fish, eggs, fruit, legumes, nuts, and seeds were infrequently consumed. Intakes of Fe and Zn could not fully reach the Recommended Nutrient Intake (RNIs), while the vitamins C, B6, folate, B12, and A could achieve 100% of RNIs by using optimized food pattern. Local foods that could be used to help improve the nutrients, except for Fe and Zn. The CFR were as follow: continue breastfeeding frequently; feed quality protein source food such as 3 servings/wk of all type of eggs and liver, 5 servings/wk of locally available flesh of fish; provide 2 servings/wk of enriched/fortified baby porridge; offer plant protein foods (legumes, nuts or seeds) 2 servings/wk including 1 serving/wk of mung bean porridge. Locally available foods had potential to improve diet quality of infants aged 6-11 mo, providing that the consumption frequency is increased. Consumption of food sources for Fe and Zn needs to be improved in terms of both portion and frequency.

Unhealthy Snack Food and Beverage Consumption Is Associated with Lower Dietary Adequacy and Length-for-Age z-Scores among 12–23-Month-Olds in Kathmandu Valley, Nepal

ABSTRACTBackgroundConsumption of unhealthy snack foods and beverages (USFBs) in low- and middle-income countries (LMICs) is rising, with global awareness increasing about risks of overnutrition. However, little is known about the relation between USFB consumption and young children's diet/nutritional outcomes in contexts where nutrient density of complementary foods is often low.ObjectivesThis study assessed the association of high USFB consumption, compared with low consumption, with nutrient intakes, dietary adequacy, iron status, and growth in young children in Kathmandu Valley, Nepal.MethodsA cross-sectional survey was conducted in a representative sample of 745 primary caregivers of children aged 12–23 mo. Food consumption was measured through quantitative 24-h recalls, and child anthropometric measurements and capillary blood samples were collected. Using adjusted linear/logistic regression models, nutrient intakes, dietary adequacy, length-for-age and weight-for-length z-scores (LAZ and WLZ, respectively), and iron status were compared between lowest and highest tertiles of consumption based on the contribution of USFBs to total energy intakes (TEIs). Mediation of the relation between USFB consumption and LAZ via lowered dietary adequacy was explored using structural equations modeling.ResultsOn average, USFBs contributed 46.9% of TEI among the highest tertile of consumers, compared with 5.2% of TEI among the lowest. Compared with low-USFB consumers, high-USFB consumers had lower nutrient intakes and a greater proportion were at risk of inadequate intakes for 8 nutrients. Mean LAZ was nearly 0.3 SD lower among high-USFB consumers than low consumers (P = 0.003), with this relationship partially mediated through dietary adequacy. No associations were found with stunting prevalence or iron status. Prevalence of overweight/obesity was low.ConclusionsIn this LMIC context, high USFB consumption among young children was associated with inadequate micronutrient intakes, which can contribute to poor growth outcomes. Addressing increased availability of USFBs in LMIC food systems should be a priority for policies and programs aiming to safeguard child nutrition.

Using a Community-Based Early Childhood Development Center as a Platform to Promote Production and Consumption Diversity Increases Children's Dietary Intake and Reduces Stunting in Malawi: A Cluster-Randomized Trial

ABSTRACTBackgroundChildren in Malawi face nutritional risks related to low-quality diets and chronic malnutrition.ObjectiveThis study evaluated the impact of a 1-y early childhood development (ECD) center–based agriculture and nutrition intervention aimed at improving household production diversity, maternal knowledge on child nutrition and feeding practices, and children's diets and anthropometric measures.MethodsA longitudinal cluster-randomized controlled trial was implemented in 60 community-based childcare centers (CBCCs), covering 1248 preschool children (aged 36–72 mo) and 304 younger siblings (aged 6–24 mo). CBCCs were randomly assigned to 1) a control group providing the Save the Children's ECD program or 2) a treatment group providing a standard ECD program with additional activities to improve nutritious food production and behavior change communication to improve diets and care practices for young children. Primary outcomes were household production and production diversity, preschooler enrollment and attendance, and dietary intake measured by quantitative 24-h recall and minimum diet diversity for younger siblings. Secondary outcomes included anthropometric measures for preschoolers and younger siblings, child development scores for preschoolers, and women's asset ownership and time use (the latter 2 are not discussed in this article). We used difference-in-difference (DID) estimates to assess impacts.ResultsCompared with the control group, preschool children in the intervention group had greater increases in nutrient intakes and in dietary diversity. No impacts on anthropometric measures were seen in preschoolers. Younger siblings in the intervention group had greater increases in height-for-age z scores than did children in the control group (DID: 0.44; P < 0.05) and greater reductions in the prevalence of stunting (DID: –17 percentage points; P < 0.05). The plausibility of the impact on growth in younger siblings was supported by effects along program impact pathways, including production of nutritious foods, caregiver knowledge, and dietary diversity.ConclusionImplementing an integrated agriculture and nutrition intervention through an ECD platform benefited children's diets and reduced stunting among younger siblings of targeted preschoolers. This trial was registered on the ISRCTN registry as ISCRCTN96497560.

Fruit production and consumption: practices, preferences and attitudes of women in rural western Kenya

This study identified practices, preferences, attitudes and decision-making for fruit consumption, fruit production, and use of income generated from these activities and assessed the contribution of fruits to closing nutritional gaps of members of smallholder farming households in Western Kenya during two different seasons. Two cross-sectional surveys were conducted, one in July/August 2013 (S1) and the other in February/March 2014 (S2). The same respondents, women responsible for food preparation in the household, were interviewed during S1 and S2 with a total of 272 women participating. Semi-structured questionnaires were used to collect data on practices, preferences and attitudes related to fruit production and consumption including a quantitative 24-h recall. On the day prior to the interview, only 25% of women during S1 and 37% during S2 had consumed fruits. Fruit consumption in grams per day differed significantly (p < 0.001) between the two seasons and was higher in S2 (mean = 106 g/d; SD = 208 g/d) compared to S1 (mean = 49 g/d; SD = 101 g/d). During both seasons, 80% or more respondents did not reach the recommended amount of 200 g of fruits per day and also had low vitamin A and C intakes, especially during S1. Simultaneously, 80% of women indicated that the household grew fruit, yet fruit production and consumption diversity were low. About 20% of respondents identified fruit consumption taboos for different household members and 37% viewed the consumption of wild fruits negatively. Integrated agriculture-nutrition programs should consider local practices, preferences and cultural attitudes in order to promote the consumption of a diversity of nutrient rich fruits and consequently better diets and nutrition.

WIC Infant and Toddler Feeding Practices Study: protocol design and implementation

The federal Special Supplemental Nutrition Program for Women, Infants, and Children (WIC), which began in the 1970s, has undergone revisions in the past several years, including revision to contents of the supplemental food "packages" in 2009 based on recommendations provided by an Institute of Medicine (IOM) committee of The National Academies. In 2010, the IOM held a workshop to examine and recommend research priorities for the program. The overall purpose of the current (ie, second) WIC Infant and Toddler Feeding Practices Study (ITFPS-2) is to conduct a nationally representative, longitudinal study of contemporary WIC infant and toddler feeding practices. This study will update earlier studies and collect information on variations in WIC program components. The study will also assess ways in which WIC may address obesity in early childhood and examine changes in feeding practices that may stem from the 2009 food package revisions. The sample is drawn from the universe of WIC sites nationally, excluding only those with an insufficient volume of eligible participants. Eligibility for the study includes the ability to be interviewed in English or Spanish. Approximately 8000 women and infants are being sampled, and ∼ 4000 are expected to participate. Eligible women are invited to participate during their WIC enrollment visit, and informed consent is sought. The design includes a core sample to be followed until the infant reaches age 2 y and a supplemental sample to be used in some cross-sectional analyses to ensure adequate representation of groups that might be underrepresented in the core sample. Participants will complete up to 11 interviews (core sample) or 4 interviews (supplemental sample) each except for the prenatal interview, which includes a quantitative 24-h recall of food intake for the infant. Eighty sites have been sampled across 26 states and 1 territory. Instruments have been developed and pretested in both English and Spanish, and interviewers have been rigorously trained. Recruitment and interviewing began in July 2013. This study will provide the only current large-sample longitudinal feeding data available on a nationally representative sample of infants in low-income families, and results will be available to inform the 2020 Dietary Guidelines for Americans for the 0- to 24-mo age group.

The Household Food Insecurity Access Scale and an Index-Member Dietary Diversity Score Contribute Valid and Complementary Information on Household Food Insecurity in an Urban West-African Setting ,

The number of urban poor is increasing quickly in West Africa, yet food security early warning systems still do not include urban areas. One reason is the lack of appropriate and internationally agreed-upon indicators to measure urban household food insecurity. Our objective was to assess the performance of the household food insecurity access scale (HFIAS) and an index-member’s dietary diversity score (IDDS) to approximate the adequacy of urban households’ diets. A survey was performed on a random cluster sample of 1056 households in Ouagadougou, Burkina Faso. Data on HFIAS and IDDS and 2 nonconsecutive household quantitative 24-h recalls were collected twice, in June-July and in November-December 2007. Diet adequacy was assessed through the household’s mean adequacy ratio (MAR) using energy and 11 micronutrients. Structural equation modeling was used to quantify the association of each candidate indicator with the MAR and receiver-operating characteristic (ROC) analyses were performed to assess their targeting performance in predicting low or high MAR. HFIAS was negatively associated with the MAR [path coefficient (P) = −7.95 × 10−3 ± 1.45 × 10−3; P < 0.001], whereas IDDS was positively associated with it (P = 5.19 × 10−2 ± 1.27 × 10−2; P < 0.001). Areas under the ROC curves ranged from 0.585 to 0.661 for HFIAS and from 0.536 to 0.629 for IDDS. In conclusion, HFIAS and IDDS performed well in approximating adequacy of urban households’ diets. They are informative indicators about urban food insecurity, promising for evaluation and monitoring but not for household targeting given their insufficient predictive power.

Food Group Diversity Indicators Derived from Qualitative List-Based Questionnaire Misreported Some Foods Compared to Same Indicators Derived from Quantitative 24-Hour Recall in Urban Burkina Faso1–5

To be useful proxies of micronutrient intake at the population level in resource-limited societies, dietary diversity indicators should be simple and easy to collect in large surveys and their accuracy needs to be assessed. The present study aimed at comparing food group diversity indicators (FGI) derived from simple qualitative list-based questionnaires (qFGI) to the same indicators derived from quantitative 24-h recalls (QFGI). Both methods were administered separately on each of 3 recall days to women in 2 districts of Ouagadougou, Burkina Faso. Data were available for a total of 526 women x recalls. This study was performed within the framework of the Women’s Dietary Diversity Project, which sought to analyze the relationships between various QFGI and the mean probability of adequacy (MPA) of women’s diets across 11 micronutrients. The comparison between paired qFGI and QFGI scores was made both in terms of accuracy of the reporting by the list-based questionnaire, taking the QFGI as the gold standard, and in terms of performance of indicators in predicting an MPA > 60%. Examination of paired QFGI-qFGI differences revealed that the more disaggregated the FGI, the higher were the mean differences in scores. Food groups most frequently misreported often corresponded to foods put in small quantities in sauces. Overreporting by list-based questionnaires was observed for indicators applying a 15-g minimum quantity of consumption for a group to count in the score and this may result in weaker performance in predicting the MPA. These results highlight trade-offs between accuracy and simplicity when operationalizing FGI through qualitative questionnaires.

Micronutrient Adequacy of Women’s Diet in Urban Burkina Faso Is Low1–3

In developing countries, urban populations are deemed to have better access to a wider variety of foods than their rural counterparts. Yet, data on micronutrient status are scarce and the impact of urban food consumption behaviors on micronutrient adequacy is not well known. The objective of this study was to assess individual micronutrient adequacy of the diet along with food consumption behaviors of women of reproductive age in Ouagadougou, Burkina Faso. A cross-sectional survey of 182 women was conducted in 2 districts of the city. Nutrient intakes were derived from 3 nonconsecutive quantitative 24-h recalls for each woman. Balance in macronutrients was in the range of recommendations except that mean sugar intake was somewhat high. Mean probability of adequacy across 11 micronutrients was low (0.38). The most problematic micronutrients were vitamin B-12 (only 4% of our sample had sufficient intake), folate (12%), riboflavin (13%), and niacin (20%). Higher intakes of organ meat, flesh foods, vitamin A- and vitamin C-rich fruits and vegetables, and legumes and nuts were significantly associated with lower risk of micronutrient inadequacy. Ready-to-eat foods bought outside the home provided 46% of overall energy intake, 52% of fat intake, and 72% of sugar intake but were not associated with micronutrient inadequacy (P > 0.05). These results highlight the low micronutrient intakes among women of reproductive age in Burkina Faso, even in an urban area.

Contribution of complementary foods to the total daily water needs of urban Guatemalan infants

Estimates of adequate intake (AI) for water only became available in 2005. The daily water AI for 6-12-month-old infants of both sexes is 800 mL. The present study aimed to estimate the water intake of urban infants receiving both breast milk and complementary feeding (CF) and to compare them with the reference AI. Sixty-four infants, 42 boys and 22 girls, aged 6-12 months on enrollment, from a low-income district of Guatemala City, were recruited to the study. Quantitative 24-h recalls and breastfeeding histories were collected in three serial interviews. The quantity of water was estimated from recipes and food composition moisture values for the CF items reported. The amount of breast milk needed to complement foods and beverages in meeting the individual energy needs was calculated, and breast milk's water contribution was derived accordingly. The total quantity of water in beverages, including human milk, liquids in recipes and moisture of foods, was tabulated as the infants' daily intake. Some 56.3% of the water needs for boys and 41.1% for girls were satisfied by just water obtained from plain water, other complementary beverages and moisture of foods within CF, exclusive of breast milk. Adding the estimated breast milk intake, the median water intake for the infant sample was essentially equal to the 800 mL of the AI. The infants in this low-income community are approximating the recommended AI for daily water through the currently selected pattern of lactation and CF.

Assessment of child feeding practices using a summary index: stability over time and association with child growth in urban Madagascar

BackgroundPrevious studies investigating the association between an infant and child feeding index (ICFI) and length-for-age were based on a cross-sectional design and on the assumption that data collected with brief recalls could provide information about more enduring processes. ObjectivesThe objectives were to test the stability of the individual ICFI values over time and to investigate how they relate to length-for-age z score (LAZ) and weight-for-length z score (WLZ) at the end of the study. DesignThis prospective cohort study included 363 children aged 6–17 mo who were visited 3 times over 6 mo. A cross-sectional ICFI (CS-ICFI) was constructed for each visit by using data on feeding practices and data from quantitative 24-h recalls. A longitudinal ICFI (L-ICFI) was constructed with use of the 3 CS-ICFIs. The stability of the CS-ICFI was assessed by using the variance of the repeatability coefficient (s2r). ResultsStability of the CS-ICFI was shown by the value of 0.704 (95% CI: 0.625, 0.805) of the s2r, which differed significantly from 1 (P < 0.0001). There was no significant association between the CS-ICFIs and LAZ or WLZ at visit 3. In contrast, when moving from low to high L-ICFI, there was a highly significant 0.5 z score difference in mean LAZ at visit 3 (P = 0.0008). The L-ICFI was not associated with WLZ. ConclusionsThe ICFI constructed by using data collected with brief recalls can provide information about feeding in the long term. However, the absence of association with LAZ suggests a lack of precision that can be reduced by using an ICFI based on repeated measurements.

Association of a summary index of child feeding with diet quality and growth of 6–23 months children in urban Madagascar

The assessment of child feeding practices has received renewed attention through the development of an infant and child feeding index (ICFI). However, the advantages and shortcomings of such a summary index are still not well known. The aim of this study was to assess the usefulness of ICFI as an analytical tool (1) by studying its association with complementary food energy intake and mean micronutrient density adequacy (MMDA) and (2) by testing whether ICFI and its components are associated with length-for-age z-score (LAZ) of 6-23 months children in urban Madagascar. ICFI was constructed using data from questionnaires on feeding practices and quantitative 24-h recalls (n=1589). Multivariate analysis was used to control for household wealth and other confounding factors. ICFI was positively correlated with complementary food energy intake (P<0.0001) and MMDA (P<0.0001). ICFI was associated with LAZ among 6-8 months children (P=0.02). For all ages combined, there was a tendency towards an association that did not reach statistical significance (P=0.08). Among feeding practices that formed ICFI, breastfeeding was associated with LAZ (P=0.03) but not in the expected direction with +0.16 z-score difference in favour of non-breast-fed children. When breastfeeding was removed and introduced separately into the multivariate model, the relationship between the modified ICFI and LAZ became significant (P=0.02). Findings suggest that the ICFI could be a useful analytical tool, which needs however to be constructed according to its final use and which should be adapted to each context.

Underreporting of Food Intake by Dietary Recall Is Not Universal: A Comparison of Data from Egyptian and American Women

Underreporting of dietary intake has been observed consistently in food consumption surveys in affluent societies and in clinical studies in a variety of settings. Almost one third of quantitative 24-h recalls provided by adults in U.S. surveys appear to result in estimates that are biologically implausible. Underreporting has been linked to obesity in both the U.S. and Europe, with heavier individuals underreporting to a greater degree than lean persons. A relative dearth of data exists from developing countries and those in transition to address the question whether such underreporting is universal. We present the first data from a large survey of women in a rapidly urbanizing developing country to address this question. More than 4500 adult women in Egypt provided quantitative 24-h recalls of food intake on the previous day in 1993-1994, and weights and heights were measured. We compared the data, in terms of the ratio of reported energy intake to estimated basal metabolic rate, to data from 3010 women in the 1994-1996 U.S. Continuing Survey of Food Intake by Individuals, on whom quantitative 24-h recalls were also conducted. The Egyptian women reported food intakes consistent with FAO/WHO recommendations for energy intakes for women of comparable activity levels, whereas the data for U.S. women showed underreporting consistent with other U.S. surveys. Only 10% of Egyptian women reported energy intakes below accepted criteria for plausibility, compared with one third of American women. We discuss possible reasons for this difference, including cultural and food supply differences, and methodological differences between the two surveys.
