Equity and Distributional Impact on Stunting of a Nutritional Package Targeting Children Aged 6-36 Months in China: Findings from a Modeling Study.

BACKGROUND: Despite rapid economic development, child stunting remains a persistent problem in China. Stunting prevalence varies greatly across geographical regions and wealth groups. To address child undernutrition, the Ying Yang Bao (YYB) nutritional package has been piloted in China since 2001. OBJECTIVE: We aimed to evaluate the distributional impact of a hypothetical rollout of the YYB nutritional package on child stunting across provinces and wealth groups in China, with a specific focus on equity. METHODS: We used data from China Family Panel Studies and built on extended cost-effectiveness analysis methods. We estimated the distributional impact of a 12-month YYB program targeting children aged 6-36 months across 25 provinces and two wealth groups along three dimensions: the cost of the YYB program; the number of child stunting cases averted by YYB; and the cost per stunting case averted. Children in each province were divided into poverty and non-poverty groups based on the international poverty line of $5.50 per day. We also conducted a range of sensitivity analyses. RESULTS: We showed that 75% coverage of YYB could avert 1.9 million stunting cases among children aged 6-36 months, including 1.3 million stunting cases among children living under the poverty line, at a total cost of ¥5.4-6.2 billion ($1.5-1.8 billion) depending on the type of YYB delivery. The cost per stunting case averted would greatly vary across Chinese provinces and wealth groups, ranging from ¥800 (around $220, Chongqing province) to ¥23,300 (around $6600, Jilin province). In most provinces, the cost per stunting case averted would be lower for children living under the poverty line. CONCLUSIONS: YYB could be a pro-poor nutritional intervention package that brings substantial health benefits to poor and marginalized Chinese children, but with large variations in value for money across provinces and wealth groups. This analysis points to the need for prioritization across provinces and a targeted approach for YYB rollout in China.

Evaluation of Nutrition Interventions in Children in Conflict Zones: A Narrative Review.

Food and nutrition insecurity becomes increasingly worse in areas affected by armed conflict. Children affected by conflict, or in war-torn settings, face a disproportionate burden of malnutrition and poor health outcomes. As noted by humanitarian response reviews, there is a need for a stronger evidence-based response to humanitarian crises. To achieve this, we systematically searched and evaluated existing nutrition interventions carried out in conflict settings that assessed their impact on children's nutrition status. To evaluate the impact of nutrition interventions on children's nutrition and growth status, we identified published literature through EMBASE, PubMed, and Global Health by using a combination of relevant text words and Medical Subject Heading terms. Studies for this review must have included children (aged ≤18 y), been conducted in conflict or postconflict settings, and assessed a nutrition intervention that measured ≥1 outcome for nutrition status (i.e., stunting, wasting, or underweight). Eleven studies met the inclusion and exclusion criteria for this review. Five different nutrition interventions were identified and showed modest results in decreasing the prevalence of stunting, wasting, underweight, reduction in severe or moderate acute malnutrition or both, mortality, anemia, and diarrhea. Overall, nutrition interventions in conflict settings were associated with improved children's nutrition or growth status. Emergency nutrition programs should continue to follow recent recommendations to expand coverage and access (beyond refugee camps to rural areas) and ensure that aid and nutrition interventions are distributed equitably in all conflict-affected populations.

Health Economics of Nutrition Intervention in Asia: Cost of Malnutrition.

Asia has recorded the fastest economic growth in the world. However, some countries are still struggling with economic stagnation and poverty. Even in the emerging countries, there are economic disparities between urban and rural areas within a country. Reflecting the situations, nutritional issues in Asia came to be the antithetical situation of excess and insufficiency. The rate of overweight and obesity keeps increasing, especially in emerging countries. Meanwhile, underweight is still a critical problem in the region. Although the importance of nutrition is well recognized for social and economic development, it is difficult to identify the immediate outcome of nutrition interventions. Evidence-based decision-making is an important element of quality health care and efficiency and effectiveness are always key words. Along with enhanced attention to accountability and transparency of budget use in health services, attention to the economic evaluation of nutrition interventions has increased in recent years. In this symposium, we will review the current situation of nutritional issues and economic evaluation of nutrition interventions in Asia through experience of an international organization, the basis and trends for health care economics, and also efforts have been made in an Asian country. Discussion will be made about efficient and effective ways to evaluate projects/programmes for nutrition improvement.

Addressing the double burden of malnutrition with a common agenda.

Addressing malnutrition in all its forms represents an integrated agenda addressing the root causes of malnutrition at all stages of the life course. The issue is not about choosing between addressing undernutrition in the poor versus overnutrition in the affluent. We must recognize that the interventions required to address stunting are different from those needed to reduce underweight and wasting. In most developing regions, there is a coexistence between underweight and stunting in infants and children, while in the adult population it may be overweight and stunting. Malnutrition in all its forms refers to both underweight and overweight. Underweight is defined by a low weight-for-age, a child is underweight because of wasting (low weight-for-height) or stunting (low length-for-age). Stunting refers to low height-for-age independent of their weight-for-age, some stunted children may have excess weight for their stature length. Overweight is excess weight-for-length/-height or high-BMI-for-age. The prevention of nutrition-related chronic diseases is a life-long process that starts in fetal life and continues throughout infancy and later stages of life. It requires promoting healthy diets and active living at each stage. The agenda requires that we tackle malnutrition in all its forms.

Nutritional supplementation: the additional costs of managing children infected with HIV in resource-constrained settings.

OBJECTIVE: To explore the financial implications of applying the WHO guidelines for the nutritional management of HIV-infected children in a rural South African HIV programme. METHODS: WHO guidelines describe Nutritional Care Plans (NCPs) for three categories of HIV-infected children: NCP-A: growing adequately; NCP-B: weight-for-age z-score (WAZ) ≤-2 but no evidence of severe acute malnutrition (SAM), confirmed weight loss/growth curve flattening, or condition with increased nutritional needs (e.g. tuberculosis); NCP-C: SAM. In resource-constrained settings, children requiring NCP-B or NCP-C usually need supplementation to achieve the additional energy recommendation. We estimated the proportion of children initiating antiretroviral treatment (ART) in the Hlabisa HIV Programme who would have been eligible for supplementation in 2010. The cost of supplying 26-weeks supplementation as a proportion of the cost of supplying ART to the same group was calculated. RESULTS: A total of 251 children aged 6 months to 14 years initiated ART. Eighty-eight required 6-month NCP-B, including 41 with a WAZ ≤-2 (no evidence of SAM) and 47 with a WAZ >-2 with co-existent morbidities including tuberculosis. Additionally, 25 children had SAM and required 10-weeks NCP-C followed by 16-weeks NCP-B. Thus, 113 of 251 (45%) children were eligible for nutritional supplementation at an estimated overall cost of $11 136, using 2010 exchange rates. These costs are an estimated additional 11.6% to that of supplying 26-week ART to the 251 children initiated. CONCLUSIONS: It is essential to address nutritional needs of HIV-infected children to optimise their health outcomes. Nutritional supplementation should be integral to, and budgeted for, in HIV programmes.

Onset and evolution of stunting in infants and children. Examples from the Human Nutrition Collaborative Research Support Program. Kenya and Egypt studies.

The etiology of the early onset of stunting is diverse among populations of varying biological, environmental and cultural circumstances. This is exemplified within the Nutrition CRSP project, which took place in three different populations and ecological conditions. Within each study area a different mix and varying proportions of causative factors were identified. At least in Kenya, and probably in Mexico, the problem has its antecedents in prepregnancy and pregnancy. Powerful determinants of the infants' size at birth and during the first 6 months of life are maternal size upon entry into pregnancy, and weight and fat gain during pregnancy and lactation. In all three countries a low pregnancy weight gain was observed. Notably in Kenya, where the energy intake of the mother decreases progressively throughout pregnancy, not only do mothers gain only half as much as European or North American women, but they even lose weight and fat in the last month of pregnancy, and some mothers gain no weight or lose weight during the whole of pregnancy. Mothers in Kenya start lactation with relatively poor fat stores. Although their energy intake increases somewhat during lactation, preliminary estimates suggest that these increases may be insufficient to maintain their bodily integrity, to carry out their normal tasks of daily living, and to produce a sufficient amount of milk for optimal infant growth. In addition to an energy deficit, diet quality is a problem, particularly in Kenya and Mexico and less so in Egypt. Intakes of animal products and animal protein are very low. Zinc and iron intakes are not only low, but the bioavailability of these nutrients is poor because of the high phytate, fiber and tea content of the diet. Also vitamin B12 intake is extremely low, and at least mild-to-moderate iodine deficiency (IDD) is present in Kenya. The above micronutrients have been demonstrated to affect the linear growth of the Kenyan children, even after confounding factors have been controlled. The early use of supplemental feeding in Kenya is a double-edged sword. On the one hand, there is a slight increase in febrile illness and possible displacement of breast milk intake in the supplemented infants, although mothers do not decrease breast feeding frequency and duration. On the other hand, even the modest amounts of available zinc and B12 in supplemental foods appear to have a positive effect on linear growth.(ABSTRACT TRUNCATED AT 400 WORDS)

PIP: Findings from the Nutritional Collaborative Research Support Program (CRSP) in Kenya, Mexico, and Egypt demonstrate how the etiology of the early onset of stunting varies among populations of varying biological, environmental, and cultural circumstances. In Kenya, and probably Mexico, the problem has its antecedents in prepregnancy and pregnancy. Maternal size upon entry into pregnancy and weight and fat gain during pregnancy and lactation are powerful determinants of an infant's size at birth and during the first six months of life. Low pregnancy weight gain was observed in all three countries. Mothers in Kenya even lose weight and fat in the last month of pregnancy, with some gaining no weight or losing weight during the whole of pregnancy. Mothers in Kenya begin lactation with relatively poor fat stores, thus possibly unable to produce a sufficient amount of milk for optimal infant growth even though their energy intake increases somewhat during lactation. Intakes of animal products and animal protein are also low especially in Kenya and Mexico. Intakes of zinc, iron, vitamin B12, and iodine are low, and have been shown to affect the linear growth of the Kenyan children even after controlling for confounding factors. The early use of supplemental feeding in Kenya positively affects linear growth, yet increases febrile illness and possibly displaces breast milk intake in supplemented infants. Morbidity negatively affects attained length in six-month old infants and the rate of linear growth, while cultural patterns of child rearing also appear important for growth. A major deceleration of growth occurs in the first six months of life; from 18 months onward the quantity and quality of diet and environmental factors do not permit catch-up to the normal or near normal centiles observed in newborns.

An interdisciplinary nutrition assessment and intervention protocol for children with disabilities.

Because of the multifactorial nature of the nutrition problems associated with developmental disabilities, a well-organized, interdisciplinary effort is necessary to deal with such problems. A team composed of professional and support staff, the client, and the family needs to be involved in an integrated approach to service. The team members share their knowledge and expertise in developing an individual program plan to meet identified needs. This article describes the development and implementation of a prototype for interdisciplinary nutritional evaluation and intervention in an outpatient setting. In 1987, a Regional Nutrition and Feeding Diagnosis and Evaluation Clinic was established through a contractual agreement between the University of Georgia University Affiliated Program and St. Mary's Hospital in Athens, GA. The purposes of the clinic are twofold: to offer direct services to developmentally disabled infants and children who require outpatient services and to provide a unique community-based interdisciplinary training experience for graduate students in nutrition and other health disciplines. The interdisciplinary treatment protocol is based on current knowledge in the treatment of developmental disabilities.

Linear growth of low income preschool children receiving a zinc supplement.

The effects of a zinc supplement on growth velocity were assessed in a double-blind, pair-matched controlled study in 40 children with low growth percentiles. Participants were low-income Spanish-American children, 2 to 6 yr of age with heights below the 10th percentile and nutritional or biochemical evidence of zinc deficiency. After 1 yr, the mean height velocity of the zinc-supplemented children was slightly, but significantly (p less than 0.005), greater than that of control children. This effect was primarily due to a greater height achievement of the zinc-supplemented boys. Increases in height-for-age z-scores were also significant for the supplemented males (p less than 0.001) and for the combined sexes (p less than 0.05). This study indicates the existence of a growth-limiting syndrome of mild zinc deficiency in children.
