Low dietary diversity is a predictor of child stunting in rural Bangladesh

Background/Objectives:Dietary diversity is associated with overall quality and nutrient adequacy of the diet in low-income countries. We determined the association between dietary diversity and stunting among children aged 6–59 months in rural Bangladesh.Subjects/Methods:In total, 165 111 under-fives who participated in the National Surveillance Project in 2003–2005 were included in the analysis. Dietary diversity score (DDS) was constructed through the summation of the number of days each of the nine food groups was consumed in the previous week. The association between stunting and DDS was determined adjusting for confounders using logistic regression models. All analyses were performed separately for children aged 6–11, 12–23 and 24–59 months.Results:One-half of the children were stunted. In multivariate analyses, compared with low DDS, high dietary diversity was associated with a 15, 26 and 31% reduced odds of being stunted among children aged 6–11, 12–23 and 24–59 months, respectively, after adjusting for all potential confounders (odds ratio (OR)=0.85, 95% confidence interval (CI): 0.76–0.94; OR=0.74, 95% CI: 0.69–0.79; OR=0.69, 95% CI: 0.66–0.73). In all groups, children who were still breastfed were more likely to have limited diversity (OR=1.88, 95% CI: 1.32–2.67; OR=1.71, 95% CI: 1.52–1.92; OR=1.15, 95% CI: 1.11–1.19). Those having diarrhea in the past week and coming from families with low socioeconomic status were more likely to have decreased diversity (P<0.05).Conclusions:Reduced dietary diversity is a strong predictor of stunting in rural Bangladesh. The inclusion of a variety of food groups into complementary foods may be essential to improve child nutritional status.

Program Experience with Micronutrient Powders and Current Evidence

The efficacy of micronutrient powders (MNP) in the treatment of anemia in moderately anemic children aged 6-24 mo has been clearly demonstrated. The evidence of the effectiveness of MNP in large-scale programs, however, is scarce. This article describes the program experience and findings of large-scale MNP distribution in refugee camps and in an emergency context in Bangladesh, Nepal, and Kenya. The MNP contained 15-16 micronutrients as per the WHO/World Food Programme/UNICEF joint statement, whereas the iron content was reduced to 2.5 mg from NaFeEDTA in a malaria-endemic area in Kenya. Hundreds of thousands of children aged 6-59 mo and pregnant and lactating women were targeted to consume MNP either daily or every other day over an extended period of time. Extensive social marketing campaigns were undertaken to promote regular use of the product. A number of studies were embedded in the programs to assess the impact of MNP on the nutritional status of target beneficiaries. Some improvements in anemia prevalence estimates were observed in particular subgroups, but other results did not show significant improvements. A significant decrease in the prevalence of stunting was observed in Nepal and Kenya but not in Bangladesh. Diarrhea episodes decreased significantly among children receiving MNP in Nepal. A key challenge is to ensure high MNP acceptance and adherence among beneficiaries. Investigation of non-nutritional causes of anemia is warranted in settings with high compliance but no improvement in hemoglobin status. Further investigation into the most appropriate manner to use MNP in malaria endemic settings is warranted.

Understanding low usage of micronutrient powder in the Kakuma Refugee Camp, Kenya: findings from a qualitative study.

Background Home fortification with micronutrient powder has been shown to be a low-cost, feasible, and effective approach to address micronutrient deficiencies. A large-scale program distributing micronutrient powder to approximately 50,000 refugees was implemented at the Kakuma Refugee Camp in Kenya. Uptake of the micronutrient powder at distribution points dropped nearly 70%, from 99% to a low of 30%, and remained at 45% to 52% despite increased social marketing efforts. Objective To identify factors at the distal and proximal levels leading to the low uptake of micronutrient powder through a qualitative inquiry. Methods In-depth interviews were conducted with community leaders, stakeholders, implementing partners, and beneficiaries. Direct observations of food preparation and child feeding were conducted. Focus group discussions were employed to examine perceptions and practices of beneficiaries regarding micronutrient powder use. Results Superficial formative research and lack of interagency coordination led to insufficient social marketing prior to the program. In addition, community health workers were inadequately trained. This resulted in inadequate communication regarding the health benefits and use of micronutrient powder to the beneficiaries. Reliance on personal experiences with micronutrient powder and issues with its packaging, in part, led to confusion and deleterious rumors, resulting in decreased uptake of micronutrient powder at distribution points. Conclusions A successful micronutrient powder program requires careful design, with emphasis on conducting thorough formative research, ensuring the involvement and commitment of all stakeholders from the outset, investigating the role of cultural factors, and ensuring provision of sufficient, adequate, and timely information to the beneficiaries.

Iron-fortified milk and noodle consumption is associated with lower risk of anemia among children aged 6–59 mo in Indonesia

BACKGROUND Anemia is common among children in developing countries and is associated with decreased cognitive and physical development. Iron-fortified foods may decrease child anemia. OBJECTIVE The objective was to describe the association between iron-fortified milk and iron-fortified noodle consumption and anemia in children aged 6-59 mo. DESIGN Consumption of fortified milk and fortified noodles and child anemia were assessed in 81,885 families from rural and 26,653 families from urban slum areas in Indonesia. RESULTS The proportions of children who received fortified milk and noodles were 30.1% and 22.6%, respectively, in rural families and 40.1% and 48.9%, respectively, in urban families. The prevalence of anemia among children from rural families was 55.9% and from urban families was 60.8%. Children from rural and urban families were less likely to be anemic if they received fortified milk [odds ratio (OR): 0.76; 95% CI: 0.72, 0.80 (P < 0.0001) and OR: 0.79; 95% CI: 0.74, 0.86 (P < 0.0001), respectively] but not fortified noodles [OR: 0.98; 95% CI: 0.93, 1.09 (P = 0.56) and OR: 0.95; 95% CI: 0.88, 1.02 (P = 0.16), respectively] in multiple logistic regression models with adjustment for potential confounders. In rural families, the odds of anemia were lower when the child who consumed fortified milk also consumed fortified noodles or when the child who consumed fortified noodles also consumed fortified milk. CONCLUSIONS In Indonesia, consumption of fortified milk and noodles was associated with decreased odds of child anemia. Iron-fortified milk and noodles may be a strategy that could be applied more widely as an intervention to decrease child anemia.

Consumption of micronutrient-fortified milk and noodles is associated with lower risk of stunting in preschool-aged children in Indonesia

Background Stunting is highly prevalent in developing countries and is associated with greater morbidity and mortality. Micronutrient deficiencies contribute to stunting, and micronutrient-fortified foods are a potential strategy to reduce child stunting. Objective To examine the relationship between the use of fortified powdered milk and noodles and child stunting in a large, population-based sample of Indonesian children. Methods Consumption of fortified milk and fortified noodles was assessed in children 6 to 59 months of age from 222,250 families living in rural areas and 79,940 families living in urban slum areas in Indonesia. Results The proportions of children who consumed fortified milk and fortified noodles were 34.0% and 22.0%, respectively, in rural families, and 42.4% and 48.5%, respectively, in urban families. The prevalence of stunting among children from rural and urban families was 51.8% and 48.8%, respectively. Children from rural and urban families were less likely to be stunted if they consumed fortified milk (in rural areas, OR = 0.87; 95% CI, 0.85 to 0.90; p < .0001; in urban areas, OR = 0.80; 95% CI, 0.76 to 0.85; p < .0001) or fortified noodles (in rural areas, OR = 0.95; 95% CI, 0.91 to 0.99; p = .02; in urban areas, OR = 0.95; 95% CI, 0.91 to 1.01; p = .08) in multiple logistic regression models adjusted for potential confounders. In both rural and urban families, the odds of stunting were lower when a child who consumed fortified milk also consumed fortified noodles, or when a child who consumed fortified noodles also consumed fortified milk. Conclusions The consumption of fortified milk and noodles is associated with decreased odds of stunting among Indonesian children. These findings add to a growing body of evidence regarding the potential benefits of multiple micronutrient fortification on child growth.

Relationship of the Presence of a Household Improved Latrine with Diarrhea and Under-Five Child Mortality in Indonesia

We characterized the relationship of the presence of an improved latrine with diarrhea and under-five child mortality in Indonesia. The proportion of rural and urban families, respectively, without an improved latrine was 52.1% and 16.2%, with a child with a history of diarrhea in the last 7 days was 8.2% and 9.7%, and with a history of under-five child mortality was 11.1% and 8.5%. Among rural and urban families, respectively, lack of an improved latrine was associated with a child history of diarrhea in the last 7 days (odds ratio [OR] = 1.23, 95% confidence interval [CI] = 1.18-1.29, P < 0.0001; OR = 1.20, 95% CI = 1.13-1.27, P < 0.0001) and under-five child mortality (OR = 1.29, 95% CI = 1.25-1.31, P < 0.0001; OR = 1.22, 95% CI = 1.12-1.32, P < 0.0001) in separate multivariable logistic regression models adjusting for covariates. The lack of a household improved latrine is associated with diarrhea and under-five child mortality in Indonesia.

Relationship of the availability of micronutrient powder with iron status and hemoglobin among women and children in the Kakuma Refugee Camp, Kenya.

Background Micronutrient powder is a potential strategy to improve iron status and reduce anemia in refugee populations. Objective To evaluate the effect of the availability of home fortification with a micronutrient powder containing 2.5 mg of sodium iron ethylenediaminetetraacetate (NaFeEDTA) on iron status and hemoglobin in women and children in the Kakuma Refugee Camp in northwest Kenya. Methods Hemoglobin and soluble transferrin receptor were measured in 410 children 6 to 59 months of age and 458 women of childbearing age at baseline (just before micronutrient powder was distributed, along with the regular food ration) and at midline (6 months) and endline (13 months) follow-up visits. Results At the baseline, midline, and endline visits, respectively, the mean (± SE) hemoglobin concentration in women was 121.4 ± 0.8, 120.8 ± 0.9, and 120.6 ± 1.0 g/L (p = .42); the prevalence of anemia (hemoglobin < 120 g/L) was 42.6%, 41.3%, and 41.7% (p = .92); and the mean soluble transferrin receptor concentration was 24.1 ± 0.5, 20.7 ± 0.7, and 20.8 ± 0.7 nmol/L (p = .0006). In children, the mean hemoglobin concentration was 105.7 ± 0.6, 109.0 ± 1.5, and 105.5 ± 0.3 g/L (p = .95), respectively; the prevalence of anemia (hemoglobin < 110 g/L) was 55.5%, 52.3%, and 59.8% (p = .26); and the mean soluble transferrin receptor concentration was 36.1 ± 0.7, 29.5 ± 1.9, and 28.4 ± 3.2 nmol/L (p = .02), in models that were adjusted for age using least squares means regression. Conclusions In children and in women of childbearing age, the availability of micronutrient powder was associated with a small improvement in iron status but no significant change in hemoglobin in this refugee camp setting.

Provision of micronutrient powder in response to the Cyclone Sidr emergency in Bangladesh: cross-sectional assessment at the end of the intervention.

Background Micronutrient powder has been endorsed as an effective means to improve the micronutrient status of emergency-affected populations. Objective To document the experience and findings of a cross-sectional assessment of the micronutrient powder program implemented as part of the emergency response to Cyclone Sidr. Methods Micronutrient powder was distributed to 100,714 children under 5 years of age and 59,439 pregnant or lactating women severely affected by Cyclone Sidr in Bangladesh. A cross-sectional assessment, including hemoglobin and anthropometric measurements, was conducted after the completion of the micronutrient powder program among children under 5 years of age, lactating mothers, and postmenarcheal adolescent girls in the intervention area. Comparison groups for each, drawn from the control area, which had not received micronutrient powder, were assessed at the same time. Results The prevalence of anemia among children under 5 years of age was approximately 80% in both areas. Among children in the intervention area, those who consumed at least 75% of the micronutrient powder sachets had a lower prevalence of stunting than those who consumed less than 75% of the sachets (40% vs. 52%, p < .05). Among lactating mothers in the intervention area, the prevalence rates of thinness and anemia were lower among those who consumed at least 75% of the sachets than among those who consumed less than 75% of the sachets (thinness, 31% vs. 46%, p < .05; anemia, 50% vs. 61%, p = .07). For adolescent girls in the intervention and control areas, none of whom had received micronutrient powder, the prevalence rates of anemia were 52% and 45%, respectively (p = .05). Conclusions Micronutrient powder may reduce anemia among lactating mothers, when the compliance rate is high. Anemia prevalence prior to micronutrient powder distribution had not been investigated and could have been higher among children and lactating mothers in the intervention than in the control area, resulting in the negation of the potential positive impact of micronutrient powder on anemia.

Relationship of household food insecurity to anaemia in children aged 6-59 months among families in rural Indonesia

Abstract Background: Anaemia is a significant global public health problem in developing countries with adverse health effects on young children. Household food insecurity, which reflects a household’s access, availability and utilisation of food, has not been well characterised in relation to anaemia in children. Objective: To examine the relationship of household food insecurity with anaemia (Hb <11 g/dl) in children. Methods: In a cross-sectional study of 4940 rural households participating in the Indonesian Nutrition Surveillance System, household food insecurity was measured using a modified 9-item food security questionnaire and related to anaemia in children aged 6–59 months. Results: The proportion of households with an anaemic child was 56·6%. In households with and without anaemic children, the mean (SD) food insecurity score was 1·82 (1·72) vs 1·55 (1·54) (p<0·0001), respectively. In a multivariate logistic regression model, food insecurity score was related to anaemia in children (odds ratio 0·77, 95% confidence interval 0·63–0·95, p = 0·01) when the highest quintile of food insecurity score was compared with the lowest quintile, adjusting for potential confounders. Conclusion: A higher household food insecurity score is associated with greater prevalence of anaemia in children in rural families in Indonesia.

Determinants of Anemia Clustering Among Mothers and Children in Indonesia

OBJECTIVES To describe risk factors for clustering of anemia among mothers and children in Indonesia. METHODS An anemia cluster was defined as hemoglobin <12 g/dl in the mother and <11 g/dl in the youngest child, aged 6-59 months. RESULTS Anemia clustering occurred in 4907 (18.3%) of 26 809 urban families and 12 756 (15.5%) of 82 291 rural families. Maternal overweight/obesity, older child age, consumption of fortified milk by the child, use of iodized salt, vitamin A supplementation, paternal smoking and greater expenditure on animal and plant source foods were associated with lower odds of anemia clustering. Older maternal age, maternal underweight, ≥2 children in the family and >4 individuals eating from the same kitchen were associated with greater odds of anemia clustering. CONCLUSION Fortified milk, iodized salt, vitamin A supplementation and greater expenditure on plant and animal foods are among modifiable risk factors associated with lower risk of anemia clustering in Indonesia.
