Very low adequacy of micronutrient intakes by young children and women in rural Bangladesh is primarily explained by low food intake and limited diversity.

Documentation of micronutrient intake inadequacies among developing country populations is important for planning interventions to control micronutrient deficiencies. The objective of this study was to quantify micronutrient intakes by young children and their primary female caregivers in rural Bangladesh. We measured 24-h dietary intakes on 2 nonconsecutive days in a representative sample of 480 children (ages 24-48 mo) and women in 2 subdistricts of northern Bangladesh by using 12-h weighed food records and subsequent 12-h recall in homes. We calculated the probability of adequacy (PA) of usual intakes of 11 micronutrients and an overall mean PA, and evaluated dietary diversity by counting the total number of 9 food groups consumed. The overall adequacy of micronutrient intakes was compared to dietary diversity scores using correlation and multivariate regression analyses. The overall mean prevalence of adequacy of micronutrient intakes for children was 43% and for women was 26%. For children, the prevalence of adequate intakes for each of the 11 micronutrients ranged from a mean of 0 for calcium to 95% for vitamin B-6 and was <50% for iron, calcium, riboflavin, folate, and vitamin B-12. For women, mean or median adequacy was <50% for all nutrients except vitamin B-6 and niacin and was <1% for calcium, vitamin A, riboflavin, folate, and vitamin B-12. The mean PA (MPA) was correlated with energy intake and dietary diversity, and multivariate models including these variables explained 71-76% of the variance in MPA. The degree of micronutrient inadequacy among young children and women in rural Bangladesh is alarming and is primarily explained by diets low in energy and little diversity of foods.

Infant and young child feeding practices in urban Philippines and their associations with stunting, anemia, and deficiencies of iron and vitamin A.

BACKGROUND: The prevalence of stunting, underweight, and micronutrient deficiencies are persistently high in young children in the Philippines, and among other factors, suboptimal infant and young child feeding behavior may contribute to these forms of malnutrition. OBJECTIVE: To improve the understanding of contributors associated with the nutritional status of children 6 to 23 months of age living in urban areas of the Philippines. METHODS: A cross-sectional survey was conducted covering five urban centers in the Philippines. Data on infant and young child feeding and nutritional status (including wasting, stunting, underweight, anemia, iron deficiency, and vitamin A deficiency) were collected for 1,784 children. RESULTS: Among children from urban and predominantly poor and very poor households, 26% were stunted, 18% were underweight, and 5% were wasted. Forty-two percent were anemic, 28% were iron deficient, and 3% were vitamin A deficient. About half of the children were breastfed within an hour after birth, were breastfed at the time of the survey, and had been continuously breastfed up to 1 year of age. Of the factors investigated, low socioeconomic status, use of cheaper cooking fuel, and nonuse of multivitamins were all independently associated with stunting. The prevalence of anemia, iron deficiency, and vitamin A deficiency were independently associated with the same factors and poorer sanitation facilities, lower maternal education, current unemployment, and inflammation. CONCLUSIONS: These factors merit attention in future programming and interventions may include promotion of the timely introduction of appropriate fortified complementary foods, the use of affordable multiple micronutrient preparations, and measures to reduce infections.

Intakes and breast-milk concentrations of essential fatty acids are low among Bangladeshi women with 24-48-month-old children.

Maternal fat intake and adipose reserves are major sources of PUFA during lactation. The present study examined the cross-sectional relationship between prolonged breast-feeding and maternal BMI, assessed adequacy of fat intake among lactating and non-lactating mothers of children 24-48 months of age and determined breast-milk fatty acid composition. Multi-stage sampling was used to select a representative sample of mothers from two rural districts in Bangladesh (n 474). Dietary data were collected during two non-consecutive 24 h periods via 12 h in-home daytime observations and recall. The National Cancer Institute method for episodically consumed foods was used to estimate usual intake distributions. Breast milk samples were collected from ninety-eight women, and breast-milk fatty acid methyl esters were quantified using GC. Approximately 42 % of lactating v. 26 % of non-lactating mothers were underweight (BMI < 18·5 kg/m2; P = 0·0003). The maternal diet was low in total fat (approximately 8 % of mean total energy) and food sources of PUFA, including oil and animal source foods, resulting in a low estimated mean total consumption of PUFA (5·1 g/d). Almost all women were estimated to consume less than the recommended intake levels for total fat, total PUFA, α-linolenic acid (ALA) and DHA. Median breast-milk linoleic acid (8·5 % weight) and ALA (0·2 %) concentrations were among the lowest reported in the literature, in contrast with arachidonic acid (0·5 %) and DHA (0·3 %) concentrations, which were mid-range. Bangladeshi women in general, and especially those who practise prolonged breast-feeding, may benefit from increased consumption of food sources of PUFA.

Dietary intake of polyunsaturated fatty acids among breast-feeding and non-breast-feeding 24- to 48-month-old children in Bangladesh.

OBJECTIVE: The aim of the study was to assess the adequacy of polyunsaturated fatty acid intake by rural Bangladeshi children 24 to 48 months old in relation to their breast-feeding status. MATERIALS AND METHODS: Multistage sampling was used to select a representative sample of children 24 to 48 months of age from 2 rural districts in Bangladesh (n = 479). Two nonconsecutive 24-hour periods of dietary data were collected via 12-hour daytime in-home observations and recall. Breast milk intake was estimated using test weighing. The National Cancer Institute (NCI) method for episodically consumed foods was used to estimate distributions of usual food and nutrient intakes. RESULTS: Based on the estimated intake distributions, >95% of the children had usual fat intakes <30% of total energy. Among 24- to 35-month-old (younger) and 36- to 48-month-old (older) children, respectively, 4% and 16% of breast-feeding children and 31% and 41% of non-breast-feeding children were estimated to consume <10% of total energy from fat. An estimated 80% of all of the children consumed <4% of total energy as linoleic acid, and 99% consumed <1% of energy as α-linolenic acid. Younger breast-feeding children had higher estimated average docosahexaenoic acid (DHA) intakes (0.04 g DHA/day) than their non-breast-feeding counterparts (0.01 g DHA/day; P = 0.0005). Both breast-feeding and non-breast-feeding older children had estimated mean DHA intakes of 0.02 g/day (P = 0.74). CONCLUSIONS: Rural Bangladeshi children 24 to 48 months old, and especially those who have discontinued breast-feeding, may benefit from increased fat consumption.

The current high prevalence of dietary zinc inadequacy among children and women in rural Bangladesh could be substantially ameliorated by zinc biofortification of rice.

Rural Bangladeshi populations have a high risk of zinc deficiency due to their consumption of a predominantly rice-based diet with few animal-source foods. Breeding rice for higher zinc content would offer a sustainable approach to increase the population's zinc intakes. The objectives of the study were to quantify usual rice and zinc intakes in young children and their adult female primary caregivers and to simulate the potential impact of zinc-biofortified rice on their zinc intakes. We measured dietary intake in a representative sample of 480 children (ages 24-48 mo) and their female caregivers residing in 2 rural districts of northern Bangladesh. Dietary intakes were estimated by 12-h weighed records and 12-h recall in homes on 2 nonconsecutive days. Serum zinc concentrations were determined in a subsample of children. The median (25th, 75th percentile) rice intakes of children and female caregivers were 134 (99, 172) and 420 (365, 476) g raw weight/d, respectively. The median zinc intakes were 2.5 (2.1, 2.9) and 5.4 (4.8, 6.1) mg/d in children and women, respectively. Twenty-four percent of children had low serum zinc concentrations ( < 9.9 micromol/L) after adjusting for elevated acute phase proteins. Rice was the main source of zinc intake, providing 49 and 69% of dietary zinc to children and women, respectively. The prevalence of inadequate zinc intakes was high in both the children (22%) and women (73-100%). Simulated increases in rice zinc content to levels currently achievable through selective breeding decreased the estimated prevalence of inadequacy to 9% in children and 20-85% in women, depending on the assumptions used to estimate absorption. Rural Bangladeshi children and women have inadequate intakes of zinc. Zinc biofortification of rice has the potential to markedly improve the zinc adequacy of their diets.
