Livestock ownership, animal source foods and child nutritional outcomes in seven rural village clusters in Sub-Saharan Africa

BackgroundSub-Saharan Africa currently has the highest prevalence of malnutrition worldwide. In children under the age of 5 years, malnutrition can have long-term effects on physical and cognitive development, with implications at the national scale. Theoretically, livestock-based interventions are well placed to overcome constraints faced by micronutrient and/or food-based interventions. However, there is limited empirical evidence to support this hypothesis.MethodsThis study utilised agriculture, nutrition and anthropometry data from the Millennium Villages Project to investigate relationships between livestock ownership, animal source foods (ASF) consumption and child nutritional outcomes across seven rural village clusters in Sub-Saharan Africa. Village clusters were located in different agro-ecological zones and included: Bonsaaso, Ghana; Mayange, Rwanda; Mwandama, Malawi; Tiby, Mali; Pampaida, Nigeria; Potou, Senegal; and Ruhiira, Uganda. Data from 1624 households (including 1543 children) were included in the analysis.ResultsOverall, the proportion of children with stunting, underweight or wasting across the seven village clusters was 40, 18 and 5%, respectively. Livestock ownership, ASF consumption and child nutritional outcomes varied between village clusters. Households that owned livestock were generally more likely to consume associated ASF. For example, the proportion of households that consumed milk was higher in households that owned cows compared to those that did not in Pampaida, Mayange and Ruhiira (P < 0.05), while poultry meat consumption was generally higher in poultry-keeping households in Mayange and Ruhiira (P < 0.05). The relationship between ASF consumption and anthropometric measurements was complex, ranging from positively to negatively associated depending on the food commodity and village cluster. For instance, in Ruhiira, the mean weight-for-age Z score (WAZ) was significantly higher (better) in children from households that consumed eggs in the last 30 days, while in Potou, mean WAZ was significantly lower (worse) in children from households that consumed eggs in the last 30 days (P < 0.05).ConclusionsThis study contributes to the growing body of research that investigates the relationships between livestock ownership, ASF consumption and nutritional outcomes in children. Our results reveal complex patterns that vary across agro-ecological zones. More research is needed to assess seasonal variations in these factors, effects of gender roles on intra-household distribution of ASF, as well as effects of zoonotic food-borne diseases on nutritional status of children in these sites.

Greenhouse gas emissions from agricultural food production to supply Indian diets: Implications for climate change mitigation

Agriculture is a major source of greenhouse gas (GHG) emissions globally. The growing global population is putting pressure on agricultural production systems that aim to secure food production while minimising GHG emissions. In this study, the GHG emissions associated with the production of major food commodities in India are calculated using the Cool Farm Tool. GHG emissions, based on farm management for major crops (including cereals like wheat and rice, pulses, potatoes, fruits and vegetables) and livestock-based products (milk, eggs, chicken and mutton meat), are quantified and compared. Livestock and rice production were found to be the main sources of GHG emissions in Indian agriculture with a country average of 5.65kg CO2eq kg−1 rice, 45.54kg CO2eq kg−1 mutton meat and 2.4kg CO2eq kg−1 milk. Production of cereals (except rice), fruits and vegetables in India emits comparatively less GHGs with <1kg CO2eq kg−1 product. These findings suggest that a shift towards dietary patterns with greater consumption of animal source foods could greatly increase GHG emissions from Indian agriculture. A range of mitigation options are available that could reduce emissions from current levels and may be compatible with increased future food production and consumption demands in India.

Household dietary diversity and Animal Source Food consumption in Ethiopia: evidence from the 2011 Welfare Monitoring Survey.

BackgroundIt is imperative to track dietary quality and progress in nutritional outcomes in a population to develop timely interventions. Dietary diversity is a commonly used proxy to assess dietary quality in low-income countries. This study identified predictors of household dietary diversity in Ethiopia and pattern of consumption of animal source food (ASF) among households.MethodsSecondary data were analyzed from the 2011 Ethiopian Welfare Monitoring Survey (WMS). This survey used a structured questionnaire to collect socio-demographic and economic data. Dietary data were collected using a dietary diversity questionnaire measuring dietary diversity over the past 1 week. A Household Dietary Diversity Score (HDDS) was constructed according to the Food and Agricultural Organization (FAO) guidelines. Consumption of ASFs is described by its distribution among the regions and by HDDS. Multiple logistic regression analysis was fitted to identify independent predictors for HDDS.ResultsA total of 27,995 households were included in the analyses. A little over half of the study households (52.2%) had more than four household members, and 75% of households were male headed. The mean HHDS was five food groups. Cereals were the most commonly (96%) consumed food groups. Fish, egg and fruits, on the other hand, were the least consumed food groups. ASFs were consumed in greater proportion among households with higher HDDS. Being part of the higher and middle socio economic strata (P < 0.001), literacy (P < 0.01), urban residence (P < 0.01), male headed household (P < 0.01), larger family size (P <0.01) and owning livestock (P < 0.01) were positively associated with higher HDDS.ConclusionsConsidering these findings, nutrition sensitive interventions which address the problem through economic and educational empowerment and modern technologies supporting agricultural practices need to be designed to increase both local production and increased consumption.

Cross-sectional study of drivers of animal-source food consumption in low-income urban areas of Nairobi, Kenya

Malnutrition, including undernutrition and micronutrient deficiencies is a chronic problem in most developing countries. Animal-source foods (ASFs) provide essential sources of proteins and micronutrients, yet little is known about ASF consumption patterns or household preferences towards animal-source products among low-income populations. This is particularly critical for malnourished children for whom even small increases in consumption could help improve nutrition and health outcomes. This study analysed both the demand as well as the drivers and barriers for ASF consumption among households in two low-income areas in Nairobi, Kenya. Data on ASF expenditures and quantities purchased in the previous week, and reasons for consuming or not consuming ASFs were collected in a cross-sectional study from 205 randomly selected households in Korogocho and Dagoretti settlements. Self-reported reasons for consuming or not-consuming ASFs were described. Demand for ASFs was estimated using the Almost Ideal Demand System to provide measures of demand elasticity for changes in food prices and expenditures. On average households purchased 48 grams of ASFs, including fresh milk, per week per household member. Expenditure on ASFs counted for 38% (520 Kenyan Schillings) of the overall food expenditure of which, on average, 48% was spent on fresh milk. Price was the most commonly self-reported barrier for consumption, while taste was reported as the main driver for consumption. The perceived nutritional value was an important driver for consuming more commonly purchased ASFs (beef, eggs, fish and milk). For less commonly purchased ASFs (pork, sausages, sheep and goat meat, offal) taste, access and tradition were given as main reasons for not consuming. Estimated demand elasticities indicated that increases in total food expenditure would lead to greatest increase in the demand for beef meat. Price reductions would increase the demand relatively more for fish, other meats and dairy. For most ASFs better affordability would be a clear driver to increase the consumption. However, to increase the variety and quantity of ASFs eaten, other policies targeting improvements in physical access, food safety and consumer education on nutritional values and cooking methods should be considered.

Choline and one-carbon metabolite response to egg, beef and fish among healthy young men: A short-term randomized clinical study

Summary Background Homeostatic mechanisms that regulate long-term circulating concentrations of choline and one-carbon metabolites can obscure the relationship between diet and nutritional response. As such, we sought to determine the acute response of one-carbon metabolites to animal source foods enriched in one-carbon nutrients. Methods As part of a crossover feeding trial with one-week washout intervals, healthy young men (n = 40) were randomized to animal food sources of choline (eggs, beef and fish) and a fruit control. A panel of one-carbon metabolites was measured in blood and urine samples collected at baseline and throughout the 6-h study period. Results Consumption of the test foods yielded 1.1–2.7 times higher (P Conclusion Consumption of animal source foods of choline improves circulating concentrations of choline and other one-carbon metabolites in a manner that is influenced by time and the FMO3 G472A genotype. This trial was registered at clinicaltrials.gov as NCT02558673.

Child height gain is associated with consumption of animal-source foods in livestock-owning households in Western Kenya.

To clarify the pathways between household livestock and child growth by assessing the relationships between consumption of animal-source foods (ASF) and child growth and evaluating the household livestock correlates of child consumption of ASF. We conducted a longitudinal cohort study of anthropometry and 3 d feeding recalls among children <5 years old between June 2014 and May 2015. In addition, we collected data on wealth, livestock ownership and livestock diseases in the same households. We used linear and negative binomial mixed models to evaluate the relationships between household livestock characteristics, reported consumption of ASF and child growth. An 1800-household surveillance catchment area in Western Kenya within the structure of human and animal health surveillance systems. Children (n 874) <5 years old. Among children >6 months old, reported frequency of egg and milk consumption was associated with increased monthly height gain (for each additional report of consumption over 3 d: adjusted β (95 % CI)=0·010 (0·002, 0·019) cm/month and 0·008 (0·004, 0·013) cm/month, respectively). Poultry ownership was associated with higher reported frequency of egg, milk and chicken consumption (adjusted incidence rate ratio (95 % CI)=1·3 (1·2, 1·4), 1·4 (1·1, 1·6) and 1·3 (1·1, 1·4), respectively). Some livestock diseases were associated with lower reported frequency of ASF intake (livestock digestive diseases-adjusted incidence rate ratio (95 % CI)=0·89 (0·78, 1·00)). Child height gain was associated with milk and egg consumption in this cohort. ASF consumption was related to both household livestock ownership and animal health.

Vitamin B-12 Concentrations in Breast Milk Are Low and Are Not Associated with Reported Household Hunger, Recent Animal-Source Food, or Vitamin B-12 Intake in Women in Rural Kenya

Background: Breast milk vitamin B-12 concentration may be inadequate in regions in which animal-source food consumption is low or infrequent. Vitamin B-12 deficiency causes megaloblastic anemia and impairs growth and development in children.Objective: We measured vitamin B-12 in breast milk and examined its associations with household hunger, recent animal-source food consumption, and vitamin B-12 intake.Methods: In a cross-sectional substudy nested within a cluster-randomized trial assessing water, sanitation, hygiene, and nutrition interventions in Kenya, we sampled 286 women 1–6 mo postpartum. Mothers hand-expressed breast milk 1 min into a feeding after 90 min observed nonbreastfeeding. The Household Hunger Scale was used to measure hunger, food intake in the previous week was measured with the use of a food-frequency questionnaire (FFQ), and vitamin B-12 intake was estimated by using 24-h dietary recall. An animal-source food score was based on 10 items from the FFQ (range: 0–70). Breast milk vitamin B-12 concentration was measured with the use of a solid-phase competitive chemiluminescent enzyme immunoassay and was modeled with linear regression. Generalized estimating equations were used to account for correlated observations at the cluster level.Results: Median (IQR) vitamin B-12 intake was 1.5 μg/d (0.3, 9.7 μg/d), and 60% of women consumed <2.4 μg/d, the estimated average requirement during lactation. Median (IQR) breast milk vitamin B-12 concentration was 113 pmol/L (61, 199 pmol/L); 89% had concentrations <310 pmol/L, the estimated adequate concentration. Moderate or severe hunger prevalence was 27%; the animal-source food score ranged from 0 to 30 item-d/wk. Hunger and recent animal-source food and vitamin B-12 intake were not associated with breast milk vitamin B-12 concentrations. Maternal age was negatively associated with breast milk vitamin B-12 concentrations.Conclusion: Most lactating Kenyan women consumed less than the estimated average requirement of vitamin B-12 and had low breast milk vitamin B-12 concentrations. We recommend interventions that improve vitamin B-12 intake in lactating Kenyan women to foster maternal health and child development. The main trial was registered at clinicaltrials.gov as NCT01704105.

Role of Breastfeeding and Complementary Food on Hemoglobin and Ferritin Levels in a Cambodian Cross-Sectional Sample of Children Aged 3 to 24 Months.

BackgroundIron deficiency derives from a low intake of dietary iron, poor absorption of iron, and high requirements due to growth as well as blood loss. An estimated number of about 50% of all anemia may be attributed to iron deficiency among young children in Cambodia.MethodsA cross-sectional survey was conducted in rural Cambodia in September 2012. Villages in pre-selected communes were randomly chosen using stunting as a primary indicator of nutritional status. In total, 928 randomly selected households with children aged 3–23 months were included. Hemoglobin, ferritin, soluble transferrin receptor (sTfR), and retinol binding protein (RBP) were assessed from capillary blood samples. In addition, length/height and weight of mothers and children were taken and data on dietary diversity was collected. A child feeding index (CFI) was created. Associations between biomarkers of iron and vitamin A status and nutritional status or food intake were explored.ResultsAnemia prevalence was highest among 6- to 12-months-olds (71%). Ferritin and sTfR inversely correlated and were significantly associated with hemoglobin concentrations. The consumption of animal source foods (ASF) significantly impacts on the interaction between ferritin, sTfR and hemoglobin. Concentrations of RBP were significantly higher in children who had received a vitamin A supplement. The CFI was associated with sTfR and hemoglobin. Lower length and weight were associated with lower ferritin levels and showed an indirect effect on hemoglobin through ferritin.ConclusionNutrition programs targeting children under 2 years of age need to focus on the preparation of complementary foods with high nutrient density to sustainably prevent micronutrient deficiency and generally improve nutritional status. Future assessments of the micronutrient status should include identification of hemoglobinopathies and parasitic infections to better understand all causes of anemia in Cambodian infants and young children.Trial RegistrationGerman Clinical Trials Register DRKS00004379

Head growth of undernourished children in rural Nepal: association with demographics, health and diet

Background: Brain development in early childhood is a key determinant of later cognition, social achievement and educational success. Head circumference (HC) measurements are a simple method to assess brain growth, yet reports of these measurements are uncommon in nutritional surveys of undernourished children. Objective: To evaluate HC measurements in a population of rural Nepali children and relate these measurements to demographics, health and diet. Methods: An observational study of head growth was nested within a longitudinal evaluation of a livestock-based agricultural intervention in rural Nepal. Between 538 and 689 children (aged 6 months to 8 years) were measured (height, weight, HC) at each of six survey visits. A total of 3652 HC measurements were obtained. Results were converted to Z-scores (WHO Anthro). Results: Mean head circumference Z-scores (HCZ) diminished progressively over the first 4 years of life; a decline of 30% occurred between 3 and 4 years of age (−1.73 to −2.45, P < 0.0001). Overall, 56% of HCZ were <−2. Gender-adjusted HCZ (but not other measurements) were significantly lower for girls than boys [mean (SD) −2.31 (1.0) vs −1.99 (0.094), P < 0.0001]; girls more often had microcephaly (61% vs 50%, P < 0.0001). For children <3 years of age, HCZ were better in those who had eaten two or more animal-source foods (ASFs) within the previous 24 h [−1.69 (.05) vs −2.08 (0.10), P = 0.001] than in those who had eaten none or only one; HCZ correlated with the number of ASFs consumed (P < 0.001). Regression analyses demonstrated that the main determinants of HCZ were age, weight-for-age Z-scores (WAZ) and gender; 43% of the variance in HCZ in younger children was explained by WAZ and ASF consumption. Conclusion: HCs reflect brain size in young children; brain size is linked to cognitive function. Poor head growth represents another facet of the ‘silent emergency’ of child undernutrition. Routine HCZ assessments may contribute to better understanding of the links between poverty and cognitive development.

Dietary diversity, animal source food consumption and linear growth among children aged 1-5 years in Bandung, Indonesia: a longitudinal observational study.

Dietary diversity involves adequate intake of macronutrient and micronutrient. The inclusion of animal source foods (ASF) in the diet helps prevent multiple nutrient deficiencies and any resultant, linear growth retardation. The objective of the current study was to assess the relationship between dietary diversity, ASF consumption and height-for-age z-score (HAZ) among children aged 12-59 months old across a 1-year observation. This longitudinal observational study without controls was conducted among four age groups: 12-23 months (n 57), 24-35 months (n 56), 36-47 months (n 58) and 48-59 months (n 56). Anthropometry and dietary intake were measured during each of four visits at 16-20-week intervals. The general characteristics and other observations were only collected at baseline and endline. During the year-long study period, approximately 27 % of the children ate a diverse diet (consumed ≥6 out of 9 food groups) according to ≥3 visits. ASF consumption was high, particularly for eggs, poultry, processed meats and liquid milk. Yet, micronutrient intake inadequacy, especially of Zn, Ca, Fe and vitamin A, was highly prevalent. A multivariate regression analysis showed that the consumption of a diverse diet and ASF was not significantly associated with the HAZ at endline, after controlling for demographic characteristics and the baseline HAZ. The consumption of a diverse diet was significantly associated with Ca intake adequacy. Moreover, ASF consumption was significantly associated with adequate intake of protein and micronutrients, particularly vitamin A, Ca and Zn. Thus, the recommendation is to continue and strengthen the promotion of consuming a diverse diet that includes ASF in supporting the linear growth of young children.

How Growing Complexity of Consumer Choices and Drivers of Consumption Behaviour Affect Demand for Animal Source Foods

Many societies are spoiled for choice when they purchase meat and other livestock products, and around the globe food choice has grown dramatically in the last two decades. What is more, besides the cost and obvious health concerns influencing commodity section, an increasing proportion of choices is made to contribute to the achievement of certain ideals, such as natural resource management, climate change mitigation, animal welfare concerns and personal lifestyle. At the same time, human health considerations are becoming more important for consumption choices as richer societies, and increasingly the urban poor in low- and middle-income countries, face an unprecedented epidemic of over-consumption and associated diet-related non-communicable diseases. Animal source foods are considered significant contributors to this trend. This paper reviews this complicated arena, and explores the range of considerations that influence consumers' preferences for meat and other animal source foods. This paper also argues that deeper drivers of consumption behaviour of many foods may act in opposition to the articulated preferences for choices around animal source food consumption. We review how the returns to different causes are being valued, how emerging metrics are helping to manage and influence consumption behaviours, and draw conclusions regarding options which influence food choice.

Assessing the relative importance of dairy products to family nutrition in mixed crop-livestock production systems of Ethiopia

Livestock forms an integral part and contributes in multiple ways to the livelihoods of smallholder farmers in the crop-livestock systems of Ethiopia. This study presents empirical evidence of the relative importance of the consumption of dairy products to family nutrition and factors underlying differences among farm households. Cattle owning households (n = 270) and their under-5-year-old children (n = 225) were sampled for this study. Multiple approaches were applied for data collection, including a cross-sectional survey, in-depth household monitoring, a dietary diversity survey and anthropometric measurements of children. Household dietary diversity scores were low (4.6 ± 1.3), mainly comprising maize, Enset, green kales and milk products. The consumption of non-dairy Animal Source Foods (ASF: beef, mutton, chicken meat, eggs and fish) was low, intermittent and peaked during major religious or social festivities. Canonical Correlation Analysis (CCA) revealed substantial associations between anthropometric indices of children and socio-economic status of their parents. Specifically, predictors assigned the greatest weights, in descending order, were per capita farmland size, family size, access to clean water, crop diversity, dependency ratio, livestock holding, cash income, literacy of household head, distance to public health centres, and volume of milk available in the households. Although cow milk was identified as an important food item for children, their nutritional status was influenced by manifold factors that affect their dietary quality, health and care. Therefore, holistic approaches that embrace effective coordination among different economic sectors - notably agriculture, public health education and provision of clean water are required to achieve food and nutritional security among farming households.

Does Livestock Ownership Affect Animal Source Foods Consumption and Child Nutritional Status? Evidence from Rural Uganda

In many developing countries consumption of animal source foods (ASF) among the poor is still at a level where increasing its share in total caloric intake may have many positive nutritional benefits. This paper explores whether ownership of different livestock species increases consumption of ASF and helps improving child nutritional status, finding some evidence that both food consumption patterns and nutritional outcomes may be affected by livestock ownership in rural Uganda. Our results are suggestive that promoting (small) livestock ownership has the potential for affecting human nutrition in rural Uganda, but further research is needed to more precisely estimate the direction and size of these effects.

The Role of Animal Source Foods in Improving Nutritional Health in Urban Informal Settlements: Identification of Knowledge Gaps and Implementation Barriers

Childhood undernutrition is a health crisis in the rapidly expanding informal settlements of low-income countries worldwide. Nearly half of Kenyan children in the Kibera settlement, in Nairobi, were reported to be stunted, indicating low height-for-age. Stunted children are at greater risk for poor cognitive and physical health outcomes in the long-term, problems that tend to be perpetuated in subsequent generations. Animal-source foods (ASF) supply a calorically dense source of micro- and macronutrients, and supplementation with ASF has been shown to improve linear growth and cognition. Correspondingly, increasing consumption of ASF by pregnant women and children has been proposed as a means to disrupt the intergenerational cycle of undernutrition caused by food insecurity. Household surveys indicate that consumption of ASF is low in urban slums, despite the availability of these foods in local markets. Here we review the studies addressing the role of ASF in the diets of the urban poor and identify knowledge gaps relevant to improving nutrition by increasing consumption of ASF. Based predominantly on studies in Kibera and greater Nairobi, these gaps include determining the minimal amount and frequency of dietary ASF to prevent stunting, defining how consumer preferences, markets, and income interact to impede or promote ASF consumption, and understanding the interaction between diet and both clinical and sub-clinical enteric disease on growth outcomes.

Breastmilk Vitamin B12 Concentration is Low among Women in Western Kenya and is Not Associated with Animal Source Food Intake or Food Insecurity

Breastmilk (BM) vitamin B12 concentration varies with maternal diet, and may be inadequate in regions where animal source food (ASF) consumption is infrequent. Our objective was to measure B12 in mature BM, and examine associations with food insecurity (FI) and recent ASF intake.Between June and Aug 2014, 160 women 1‐6 mo postpartum (PP) in W. Kenya hand expressed BM one minute into a feed, following 90‐minutes of observed non‐breastfeeding. Vitamin B12 was measured using a competitive protein‐binding assay, which has been validated for BM. Food intake in the last week was measured using a food frequency questionnaire (FFQ). An ASF score was based on frequency of 10 items on the 7‐day FFQ (range 0‐70).Mean (SD) age, mo PP, and parity were 26 (6) yr, 3.7(1.4), and 3.7(2.0), respectively. Median (Q1,Q3) B12 concentration was 151 (78,247) pmol/L; 87% were &lt;330 pmol/L, the estimated adequate level. Moderate FI prevalence was 34%; the ASF score ranged from 0‐30 (M (Q1,Q3) = 9 (5,13)). Controlling for age, education, parity, SES, dietary diversity and mo PP, FI and ASF score were not significantly associated with BM B12. Although not statistically significant, there was a trend for older mothers (p=0.09) to have higher BM B12.The vast majority of women had BM B12 concentrations currently considered inadequate, suggesting that ASF intake in this population may be insufficient among breastfeeding mothers. Neither FI nor frequency of ASF intake over the last week was associated with BM B12 concentration among women in W. Kenya.

Communities' perceptions of changes in income, women's empowerment and nutrition as a result of participating in Feed the Future activities in Rwanda

While the potential of agricultural production to improve women's and children's nutrition has been recognized, there is still limited understanding of the specific pathways through which USAID‐funded Feed the Future value chains can positively impact nutritional status in vulnerable households. The current study was conducted to document the process and progress made by two Rwanda‐based Feed the Future activities, the Integrated Improved Livelihoods Program (IILP) and the Rwanda Dairy Competitiveness Program II (RDCP II), in working along agriculture‐to nutrition pathways. Specifically, we explored how increases in income, as a result of participating in Feed the Future activities, changed purchasing and consumption patterns and how engagement in the activities affected care‐seeking and care‐giving practices and women's empowerment. Interviews and discussions were conducted with activity staff and beneficiaries and, community leaders in three districts of Rwanda. Quantitative data were summarized into means and percentages. Qualitative data were coded into specific themes. Study results indicate a general improvement in program beneficiaries' income, crop production, and women's empowerment. Despite the positive trend, IILP and RDCP II face challenges that may hinder further movement along the agriculture‐to‐nutrition pathways, including demands on women's time and energy use, low consumption of animal‐sourced foods, targeting children's nutrition within the first 1,000 days, and monitoring nutrition indicators. The research highlights gaps that need to be addressed to further improve women and children's nutrition in Rwanda.

The role of animal source foods in improving nutritional health in urban informal settlements: identification of knowledge gaps and implementation barriers

Childhood undernutrition is a health crisis in the rapidly expanding informal settlements of low-income countries worldwide. Nearly half of Kenyan children in the Kibera settlement, in Nairobi, were reported to be stunted, indicating low height-for-age. Stunted children are at greater risk for poor cognitive and physical health outcomes in the long-term, problems that tend to be perpetuated in subsequent generations. Animal-source foods (ASF) supply a calorically dense source of microand macronutrients, and supplementation with ASF has been shown to improve linear growth and cognition. Correspondingly, increasing consumption of ASF by pregnant women and children has been proposed as a means to disrupt the intergenerational cycle of undernutrition caused by food insecurity. Household surveys indicate that consumption of ASF is low in urban slums, despite the availability of these foods in local markets. Here we review the studies addressing the role of ASF in the diets of the urban poor and identify knowledge gaps relevant to improving nutrition by increasing consumption of ASF. Based predominantly on studies in Kibera and greater Nairobi, these gaps include determining the minimal amount and frequency of dietary ASF to prevent stunting, defining how consumer preferences, markets, and income interact to impede or promote ASF consumption, and understanding the interaction between diet and both clinical and sub-clinical enteric disease on growth outcomes.

Consumption of Micronutrient rich Animal Source Foods and Cognitive Performance in Primary School Children in Hawassa Town, Southern Ethiopia

Consumption of Micronutrient rich Animal Source Foods and Cognitive Performance in Primary School Children in Hawassa Town, Southern Ethiopia

Community interventions for dietary improvement in Ghana.

Background. Low caregiver income and poor nutrition knowledge and skills are important barriers to achieving optimal child feeding in rural Ghana. An integrated microcredit and nutrition education intervention was implemented to address these barriers. Using a quasi-experimental design, 134 caregivers of children 2 to 5 years of age in six intervention communities were enrolled into self-selected savings and loan groups. They received small individual loans over four 16-week cycles to support their income-generating activities. Nutrition and entrepreneurial education was provided during weekly loan repayment meetings. Another 261 caregivers in six comparison communities did not receive the intervention. Data on household sociodemographic and economic characteristics, perception of income-generating activity profits, and children's consumption of animal-source foods in the previous week were collected at baseline and at four additional time points. Differences according to group (intervention vs. control) and time (baseline vs. endline) were analyzed with chi-square and Student's t-tests. The intervention and comparison groups did not differ by caregivers' age and formal education; few (35) had previous experience with microcredit loans. At endline, more intervention than comparison caregivers perceived that their business profits had increased (59% vs. 23%, p < .001). In contrast to comparison children, after 16 months of intervention children consumed more livestock meat (p =.001), organ meat (p = .04), eggs (p = .001), and milk and milk products (p < .0001) in the previous week in comparison with baseline. Integrated food-centered strategies can improve children's diets, which will enhance their nutritional status, health, and cognitive outcomes.

Households across all income quintiles, especially the poorest, increased animal source food expenditures substantially during recent Peruvian economic growth.

BackgroundRelative to plant-based foods, animal source foods (ASFs) are richer in accessible protein, iron, zinc, calcium, vitamin B-12 and other nutrients. Because of their nutritional value, particularly for childhood growth and nutrition, it is important to identify factors influencing ASF consumption, especially for poorer households that generally consume less ASFs.ObjectiveTo estimate differential responsiveness of ASF consumption to changes in total household expenditures for households with different expenditures in a middle-income country with substantial recent income increases.MethodsThe Peruvian Young Lives household panel (n = 1750) from 2002, 2006 and 2009 was used to characterize patterns of ASF expenditures. Multivariate models with controls for unobserved household fixed effects and common secular trends were used to examine nonlinear relationships between changes in household expenditures and in ASF expenditures.ResultsHouseholds with lower total expenditures dedicated greater percentages of expenditures to food (58.4% vs.17.9% in 2002 and 24.2% vs. 21.5% in 2009 for lowest and highest quintiles respectively) and lower percentages of food expenditures to ASF (22.8% vs. 33.9% in 2002 and 30.3% vs. 37.6% in 2009 for lowest and highest quintiles respectively). Average percentages of overall expenditures spent on food dropped from 47% to 23.2% between 2002 and 2009. Households in the lowest quintiles of expenditures showed greater increases in ASF expenditures relative to total consumption than households in the highest quintiles. Among ASF components, meat and poultry expenditures increased more than proportionately for households in the lowest quintiles, and eggs and fish expenditures increased less than proportionately for all households.ConclusionsIncreases in household expenditures were associated with substantial increases in consumption of ASFs for households, particularly households with lower total expenditures. Increases in ASF expenditures for all but the top quintile of households were proportionately greater than increases in total food expenditures, and proportionately less than overall expenditures.
