To determine the association between indicators of infant and young child feeding (IYCF) and anthropometric measures of nutritional status among children aged 0-23 months in a nationally representative data set. Data from the 2007 Bangladesh Demographic and Health Survey were used. Analyses were conducted using multiple linear regression and logistic regression analyses adjusted for the complex survey design of the survey, controlling for child, maternal and household characteristics, and including regional dummy variables. Bangladesh. Pairs (n 2096) of last born infants and their mothers. Exclusive breast-feeding under 6 months of age was associated with higher weight-for-height Z-score (effect size (ES) = 0·29; P < 0·05). Appropriate complementary feeding in children aged 6-8 months was associated with higher height-for-age Z-score (HAZ; ES = 0·63; P < 0·01) and higher weight-for-age Z-score (WAZ; ES = 0·30; P < 0·05). Higher dietary diversity index (DDI) was associated with higher HAZ (ES = 0·08; P < 0·01 for every 1 point higher DDI) and higher WAZ (ES = 0·04; P < 0·05). Children who achieved minimum diet diversity had higher HAZ (ES = 0·20; P < 0·05). Logistic regression models confirmed that exclusive breast-feeding was protective against wasting and DDI was protective against stunting and underweight. Our results highlight the importance of IYCF practices as determinants of child growth outcomes in this context, and reinforce the need for interventions that address the spectrum of IYCF practices, from exclusive breast-feeding to age-appropriate complementary feeding, especially diet diversity, in efforts to improve nutrition of infants and young children.

To report on the trends and determinants of undernutrition among children <5 years old in Kenya. Data from four nationwide Kenya Demographic and Health Surveys, conducted in 1993, 1998, 2003 and 2008-2009, were analysed. The Demographic and Health Survey utilizes a multistage stratified sampling technique. Nationwide covering rural and urban areas in Kenya. The analysis included 4757, 4433, 4892 and 4958 Kenyan children aged <5 years in 1993, 1998, 2003 and 2009-2009, respectively. The prevalence of stunting decreased by 4·6 percentage points from 39·9 % in 1993 to 35·3 % in 2008-2009, while underweight decreased by 2·7 percentage points from 18·7 % in 1993 to 16·0 % in 2008-2009. The effects of household wealth, maternal education and current maternal nutritional status on child nutrition outcomes have changed dynamically in more recent years in Kenya. Inadequate hygiene facilities increased the likelihood of chronic undernutrition in at least three of the surveys. Small size of the child at birth, childhood diarrhoea and male gender increased the likelihood of undernutrition in at least three of the surveys. Childhood undernutrition occurred concurrently with maternal overnutrition in some households. The analysis reveals a slow decline of undernutrition among young children in Kenya over the last three decades. However, stunting and underweight still remain of public health significance. There is evidence of an emerging trend of a malnutrition double burden demonstrated by stunted and underweight children whose mothers are overweight.

To determine the prevalence of vitamin A deficiency, infection and adequacy of vitamin A intakes among Zambian children, and the contribution of dietary vitamin A and infection to vitamin A status. A cross-sectional survey of vitamin A intakes by the 24 h recall method, vitamin A status by plasma retinol and the modified relative dose-response test, and infection by acute-phase proteins. Rural communities in Central and Eastern Provinces of Zambia. Children 2-5 years of age. The prevalence of vitamin A deficiency was 56 % by plasma retinol, 48 % with infection-adjusted plasma retinol and 22 % by the modified relative dose-response test. The majority of children (61 %) had a current infection. Vitamin A intakes were relatively high (331 to 585 μg retinol activity equivalents/d in the harvest/early post-harvest and late post-harvest seasons, respectively) and the prevalence of inadequate intakes was <1 % when compared with the Estimated Average Requirement (210 and 275 μg retinol activity equivalents/d for children aged 1-3 and 4-8 years, respectively). Elevated α-1-acid glycoprotein was negatively associated with plasma retinol (P < 0·0 0 1) and vitamin A intake was positively associated with plasma retinol (P < 0·05), but only when estimated assuming a 26:1 retinol equivalence for provitamin A from green and yellow vegetables. Infection and vitamin A intakes were significant determinants of plasma retinol. We cannot conclude which indicator more accurately represents the true vitamin A status of the population. Reasons for the persistent high prevalence of vitamin A deficiency in the presence of adequate vitamin A intakes are unclear, but the high rates of infection may play a role.

To explore associations of early infant feeding with (i) eating patterns in the second year of life and (ii) weight status in the fourth year of life in a prospective cohort of children in Scotland. Growing Up in Scotland (GUS) longitudinal birth cohort study (2005-2008). Scotland, UK. Children aged 9-12 months (n 5217) followed through to 45-48 months. Infant feeding was associated with eating patterns, defined by using SPSS two-step cluster analysis, in the second year of life. Children who were ever breast-fed compared with never breast-fed (adjusted OR = 1·48, 95 % CI 1·27, 1·73) were more likely to have a positive eating pattern (Cluster 2). Children who started complementary feeding at 4-5 months or 6-10 months compared with 0-3 months (adjusted OR = 1·32, 95 % CI 1·09, 1·59 or AOR = 1·50, 95 % CI 1·19, 1·89) were more likely to belong to Cluster 2. Breast-feeding was negatively associated with being overweight or obese in the fourth year of life compared with no breast-feeding (adjusted OR = 0·81, 95 % CI 0·81, 1·01). Introduction of complementary feeding at 4-5 months compared with 0-3 months was negatively associated with being overweight or obese (adjusted OR = 0·74, 95 % CI 0·57, 0·97). Breast-feeding and introduction of complementary feeding after 4 months were associated with a positive eating pattern in the second year of life. Introduction of complementary feeding at 4-5 months compared with 0-3 months was negatively associated with being overweight or obese.

To assess the nutritional adequacy of Seychellois children in relation to nutrients reported to be important for cognitive development. Dietary intakes were assessed by 4 d weighed food diaries and analysed using dietary analysis software (WISP version 3·0; Tinuviel Software, UK). Individual nutrient intakes were adjusted to usual intakes and, in order to investigate adequacy, were compared with the UK Estimated Average Requirements for children aged 4-6 years. Children 5 years old were followed up as part of the Seychelles Child Development Nutrition Study (SCDNS), located in the high-fish-consuming population of Mahé, Republic of Seychelles. Analysis was carried out on a sample of 229 children (118 boys, 111 girls). Children consumed a diet of which fortified cereal and milk products contributed the most to nutrient intakes. The majority (≥80 %) of children met requirements for several nutrients important for child development including Fe, folate and Se. Adjusted dietary intakes of Cu, Zn, iodine, niacin and vitamin A were below the Estimated Average Requirement or Recommended Nutrient Intake. Mean adjusted energy intakes (boys 4769 kJ/d (1139·84 kcal/d), girls 4759 kJ/d (1137·43 kcal/d)) were lower than the estimated energy requirement (boys 5104 kJ/d (1220 kcal/d), girls 5042 kJ/d (1205 kcal/d)) for 88 % of boys and 86 % of girls. Nutrition was adequate for most children within the SCDNS cohort. Low intakes of some nutrients (including Zn, niacin and vitamin A) could reflect nutritional database inaccuracies, but may require further investigation. The study provides valuable information on the adequacy of intakes of nutrients which could affect the growth and development of Seychellois children.

Misperception of social norms may result in normalising unhealthy behaviours. The present study tested the hypothesis that parents overestimate both the frequency of unhealthy snacking in pre-school children other than their own (descriptive norms) and its acceptability to other parents (injunctive norms). A cross-sectional, self-report community survey. Questions assessed the frequency with which respondents' own child ate unhealthy snacks and their beliefs about the appropriate frequency for children to snack. Perceived descriptive norms were assessed by asking parents to estimate how often other 2-4 year-old children in their area ate snacks. Perceived injunctive norms were assessed by asking them about other parents' beliefs regarding the appropriate frequency for snacks. Misperceptions were assessed from (i) the difference between the prevalence of daily snacking and parents' perceived prevalence and (ii) the difference between acceptability of daily snacking and parents' beliefs about its acceptability to others. Pre-schools and children's centres in one borough of London, UK. Parents (n 432) of children age 2-4 years. On average, parents believed that more than half of 'other' children had snacks at least daily, while prevalence data indicated this occurred in only 10 % of families. The same discrepancy was observed for perceived injunctive norms: parents overestimated other parents' acceptance of frequent snacking, with two-thirds of parents having a self v. others discrepancy. Misperceptions were identified for descriptive and injunctive norms for children's snacking. Accurate information could create less permissive norms and motivate parents to limit their child's intake of unhealthy snacks.

To assess the presence of an association between vitamin D deficiency and anaemia in Jordanian infants and toddlers, in whom both vitamin D deficiency and anaemia have previously been proved to be common separately. Cross-sectional prospective study. Department of Paediatrics, Princess Rahma Teaching Hospital, Jordan. Healthy infants and children aged 6-36 months who were seen for primary care. Out of 203 infants and toddlers included in the study, the anaemia prevalence was 40·4 %. The prevalence of anaemia among infants (n 110) was 51·8 %, whereas it was 26·9 % among toddlers (n 93). No association between vitamin D status and anaemia was found. Vitamin D deficiency is not a risk for anaemia in infants and toddlers.

Prevalence ranges to classify levels of wasting and stunting have been used since the 1990s for global monitoring of malnutrition. Recent developments prompted a re-examination of existing ranges and development of new ones for childhood overweight. The present paper reports from the WHO-UNICEF Technical Expert Advisory Group on Nutrition Monitoring. Thresholds were developed in relation to sd of the normative WHO Child Growth Standards. The international definition of 'normal' (2 sd below/above the WHO standards median) defines the first threshold, which includes 2·3 % of the area under the normalized distribution. Multipliers of this 'very low' level (rounded to 2·5 %) set the basis to establish subsequent thresholds. Country groupings using the thresholds were produced using the most recent set of national surveys. One hundred and thirty-four countries. Children under 5 years. For wasting and overweight, thresholds are: 'very low' (≈6 times 2·5 %). For stunting, thresholds are: 'very low' (≈12 times 2·5 %). The proposed thresholds minimize changes and keep coherence across anthropometric indicators. They can be used for descriptive purposes to map countries according to severity levels; by donors and global actors to identify priority countries for action; and by governments to trigger action and target programmes aimed at achieving 'low' or 'very low' levels. Harmonized terminology will help avoid confusion and promote appropriate interventions.

To investigate whether high doses of folic acid supplementation in early pregnancy are associated with child neurodevelopment at 18 months of age. The study uses data from the prospective mother-child cohort 'Rhea' study. Pregnant women completed an interviewer-administered questionnaire on folic acid supplementation at 14-18 weeks of gestation. Neurodevelopment at 18 months was assessed with the use of the Bayley Scales of Infant and Toddler Development (3rd edition). Red-blood-cell folate concentrations in cord blood were measured in a sub-sample of the study population (n 58). Heraklion, Crete, Greece, 2007-2010. Five hundred and fifty-three mother-child pairs participating in the 'Rhea' cohort. Sixty-eight per cent of the study participants reported high doses of supplemental folic acid use (5 mg/d), while 24 % reported excessive doses of folic acid (>5 mg/d) in early pregnancy. Compared with non-users, daily intake of 5 mg supplemental folic acid was associated with a 5-unit increase on the scale of receptive communication and a 3·5-unit increase on the scale of expressive communication. Doses of folic acid supplementation higher than 5 mg/d were not associated with additional increase in the neurodevelopmental scales. This is the first prospective study showing that high doses of supplementary folic acid in early pregnancy may be associated with enhanced vocabulary development, communicational skills and verbal comprehension at 18 months of age. Additional longitudinal studies and trials are needed to confirm these results.

The present study assessed the impact of the 2009 food packages mandated by the Special Supplemental Nutrition Program for Women, Infants, and Children (WIC) on perceived sales, product selection and stocking habits of small, WIC-authorized food stores. A cross-sectional study involving in-depth interviews with store managers/owners. Small, WIC-authorized food stores in eight major cities in the USA. Fifty-two store managers/owners who had at least 1 year of experience in the store prior to study participation. The WIC-approved food products (fresh, canned and frozen fruits; fresh, canned and frozen vegetables; wholegrain/whole-wheat bread; white corn/whole-wheat tortillas; brown rice; lower-fat milk (<2 %)) were acquired in multiple ways, although acquisition generally occurred 1-2 times/week. Factors such as customer requests (87 %), refrigerator/freezer availability (65 %) and profitability (71 %) were rated as very important when making stocking decisions. Most managers/owners perceived increases in sales of new WIC-approved foods including those considered most profitable (wholegrain/whole-wheat bread (89 %), lower-fat milk (89 %), white corn/whole wheat tortillas (54 %)), but perceived no changes in sales of processed fruits and vegetables. Supply mechanisms and frequency of supply acquisition were only moderately associated with perceived sales increases. Regardless of type or frequency of supply acquisition, perceived increases in sales provided some evidence for the potential sustainability of these WIC policy efforts and translation of this policy-based strategy to other health promotion efforts aimed at improving healthy food access in underserved communities.
