Development and acceptability testing of ready-to-use supplementary food made from locally available food ingredients in Bangladesh.

BACKGROUND: Inadequate energy and micronutrient intake during childhood is a major public health problem in developing countries. Ready-to-use supplementary food (RUSF) made of locally available food ingredients can improve micronutrient status and growth of children. The objective of this study was to develop RUSF using locally available food ingredients and test their acceptability. METHODS: A checklist was prepared of food ingredients available and commonly consumed in Bangladesh that have the potential of being used for preparing RUSF. Linear programming was used to determine possible combinations of ingredients and micronutrient premix. To test the acceptability of the RUSF compared to Pushti packet (a cereal based food-supplement) in terms of amount taken by children, a clinical trial was conducted among 90 children aged 6-18 months in a slum of Dhaka city. The mothers were also asked to rate the color, flavor, mouth-feel, and overall liking of the RUSF by using a 7-point Hedonic Scale (1 = dislike extremely, 7 = like extremely). RESULTS: Two RUSFs were developed, one based on rice-lentil and the other on chickpea. The total energy obtained from 50 g of rice-lentil, chickpea-based RUSF and Pushti packet were 264, 267 and 188 kcal respectively. Children were offered 50 g of RUSF and they consumed (mean ± SD) 23.8 ± 14 g rice-lentil RUSF, 28.4 ± 15 g chickpea based RUSF. Pushti packet was also offered 50 g but mothers were allowed to add water, and children consumed 17.1 ± 14 g. Mean feeding time for two RUSFs and Pushti packet was 20.9 minutes. Although the two RUSFs did not differ in the amount consumed, there was a significant difference in consumption between chickpea-based RUSF and Pushti packet (p = 0.012). Using the Hedonic Scale the two RUSFs were more liked by mothers compared to Pushti packet. CONCLUSIONS: Recipes of RUSF were developed using locally available food ingredients. The study results suggest that rice-lentil and chickpea-based RUSF are well accepted by children. TRIAL REGISTRATION: ClinicalTrials.gov NCT01553877. Registered 24 January 2012.

Role of nutrition in HIV infection: review of evidence for more effective programming in resource-limited settings.

BACKGROUND: HIV infection and malnutrition negatively reinforce each other. OBJECTIVE: For program guidance, to review evidence on the relationship of HIV infection and malnutrition in adults in resource-limited settings. RESULTS AND CONCLUSIONS: Adequate nutritional status supports immunity and physical performance. Weight loss, caused by low dietary intake (loss of appetite, mouth ulcers, food insecurity), malabsorption, and altered metabolism, is common in HIV infection. Regaining weight, particularly muscle mass, requires antiretroviral therapy (ART), treatment of opportunistic infections, consumption of a balanced diet, physical activity, mitigation of side effects, and perhaps appetite stimulants and growth hormone. Correcting nutritional status becomes more difficult as infection progresses. Studies document widespread micronutrient deficiencies among HIV-infected people. However, supplement composition, patient characteristics, and treatments vary widely across intervention studies. Therefore, the World Health Organization (WHO) recommends ensuring intake of 1 Recommended Nutrient Intake (RNI) of each required micronutrient, which may require taking micronutrient supplements. Few studies have assessed the impact of food supplements. Because the mortality risk in patients receiving ART increases with lower body mass index (BMI), improving the BMI seems important. Whether this requires provision of food supplements depends on the patient's diet and food security. It appears that starting ART improves BMI and that ready-to-use fortified spreads and fortified-blended foods further increase BMI (the effect is somewhat less with fortified-blended foods). The studies are too small to assess effects on mortality. Once ART has been established and malnutrition treated, the nutritional quality of the diet remains important, also because of ART's long-term metabolic effects (dyslipidemia, insulin resistance, obesity). Food insecurity should also be addressed if it prevents adequate energy intake and reduces treatment initiation and adherence (due to the opportunity costs of obtaining treatment and mitigating side effects).
