Effect of complementary food with small amounts of freshwater fish on whole blood n-3 fatty acids in Cambodian infants age 6-15 months

This manuscript version is made available under the CC-BY-NC-ND 4.0 license http://creativecommons.org/licenses/by-nc-nd/4.0/The impact of freshwater fish consumption on the status of long-chain n-3 fatty acids (n-3 LCPUFA) in infants in landlocked, low-income populations is unknown. We used secondary data from a randomized, single-blinded, controlled trial to evaluate the impact of daily consumption of complementary food products with small amounts of freshwater fish on whole blood n-3 LCPUFA in Cambodian infants. Infants (n=419), received daily, one of four food products for 9 months. Two products contained freshwater fish: WinFood (10% fish by dry weight) and WinFood-L (12% fish by dry weight), while two products were non-fish-based: corn-soy blends (CSB+ and CSB++). Whole blood fatty acids and breastfeeding status were assessed at baseline and endline of the intervention. The WinFood products contributed to an estimated maximum intake of 86.5 mg/day n-3 LCPUFA. There was no difference in whole blood n-3 LCPUFA among the four intervention groups or between the fish-based and the non-fish-based groups (p≥0.142). At endline, 71% of the children were still breastfed. Interaction analyses indicated a lower ratio of n-6/n-3 PUFA in non-breastfed infants in the WinFood groups compared to the CSB groups (pinteraction=0.026). Thus, a high intake of n-3 LCPUFA from breastmilk may have blurred a potential impact of small amounts of freshwater fish effect on n-3 LCPUFA status in Cambodian infants.Danida || 57-08-LIFEEuropean Commission || SMILING Project 289616Institut de Recherche pour le DéveloppementUniversity of CopenhagenCanada Research Chair in Nutritional LipidomicsWorld Food Programm

Stunting, wasting and breast-feeding as correlates of body composition in Cambodian children at 6 and 15 months of age

AbstractThe study aimed at assessing stunting, wasting and breast-feeding as correlates of body composition in Cambodian children. As part of a nutrition trial (ISRCTN19918531), fat mass (FM) and fat-free mass (FFM) were measured using2H dilution at 6 and 15 months of age. Of 419 infants enrolled, 98 % were breastfed, 15 % stunted and 4 % wasted at 6 months. At 15 months, 78 % were breastfed, 24 % stunted and 11 % wasted. Those not breastfed had lower FMI at 6 months but not at 15 months. Stunted children had lower FM at 6 months and lower FFM at 6 and 15 months compared with children with length-for-agez≥0. Stunting was not associated with height-adjusted indexes fat mass index (FMI) or fat-free mass index (FFMI). Wasted children had lower FM, FFM, FMI and FFMI at 6 and 15 months compared with children with weight-for-lengthz(WLZ) ≥0. Generally, FFM and FFMI deficits increased with age, whereas FM and FMI deficits decreased, reflecting interactions between age and WLZ. For example, the FFM deficits were –0·99 (95 % CI –1·26, –0·72) kg at 6 months and –1·44 (95 % CI –1·69; –1·19) kg at 15 months (interaction,P&lt;0·05), while the FMI deficits were –2·12 (95 % CI –2·53, –1·72) kg/m2at 6 months and –1·32 (95 % CI –1·77, –0·87) kg/m2at 15 months (interaction,P&lt;0·05). This indicates that undernourished children preserve body fat at the detriment of fat-free tissue, which may have long-term consequences for health and working capacity.</jats:p

Determination of Zinc Status in Humans: Which Indicator Should We Use?

Zinc deficiency has serious wide-ranging health consequences and is thought to be one of the most prevalent micronutrient deficiencies in the world. However, reliable indicators or biomarkers to assess zinc status are not available at present. Indirect indicators such as the prevalence of stunting or anemia, iron deficiency, as well as more direct indicators such as plasma zinc concentrations are being used at present to estimate the prevalence of zinc deficiency in populations. However, as this paper shows by using data from a recent national micronutrient survey in Vietnam, the estimates of the prevalence of zinc deficiency using these different indicators can vary widely, leading to inconsistencies. In this paper, zinc deficiency among children is four times more prevalent than iron deficiency and 2.3 times more than stunting prevalence for example. This can lead not only to confusion concerning the real extent of the prevalence of zinc deficiency in populations, but also makes it hard to inform policy on whether action is needed or not. Moreover, evaluation of programs is hampered by the lack of a clear indicator. Efforts should be made to identify the most suitable indicator to evaluate the impact of programs aimed at improving zinc status and health of populations

KEKURANGAN VITAMIN A PADA KELOMPOK BAYI DAN FAKTOR YANG BERHUBUNGAN DI KABUPATEN BOGOR

VITAMIN A DEFICIENCY AND ITS RELATED FACTORS IN INFANTS IN BOGOR DISTRICT.Background: Based on clinical indicators, vitamin A deficiency in Indonesia is not a public health problem because the prevalence of xerophthalmia has been decreased to 0.34%. But, this decrease has not been followed by a decrease of marginal deficiency of vitamin A in vulnerable groups, especially infants.Methods: The cross-sectional baseline study was conducted at Bogor District. The aim of the study was to collect information about the vitamin A status of the breastfed infant, and to look for a relationship between many factors related to it. The samples were 183 breastfed infants aged 2-0 months without chronic disease, congenital disease, severe PEM nor twins. The chi-square and the prevalence odds ratio (POR) at the 95% confidence interval were used to measure the association between variables. Multiple logistic regression analysis was used to measure the closest factors to infant's vitamin A status.Results: The study showed that 54.1% of breastfed infants were at risk of vitamin A deficiency. Based on bivariate analysis, there are two significant independent variables related to infants vitamin A status, which are maternal vitamin A status and infant infection status. Multiple logistic regression analysis showed that infection status is the closest factor to vitamin A deficiency in infants, followed by maternal vitamin A status and breast feeding frequency. There are no significant association between supplementary feeding, age, nutritional status and the infant's vitamin A status.Conclusions: Marginal vitamin A deficiency in infants aged 2-10 months is still a public health problem in the research area. The infection status is the closest factor to vitamin A deficiency in infants, followed by maternal vitamin A status and breast feeding frequency.Keywords: vitamin A deficiency, breast feeding, infection, complementary feeding, infant

Caretakers' perceptions and willingness‐to‐pay for complementary food in urban and rural Cambodia

Abstract Inadequate child nutrition during the first ‘1000 days’ is widespread in Cambodia, resulting in a high prevalence of child malnutrition. Access to processed complementary food in packages (PCFP) may support caretakers in improving diet of young children. This study aimed to evaluate the caretakers' preferences and willingness‐to‐pay (WTP) for PCFP in Cambodia. The study was conducted in urban and rural settings, involving 520 caretakers with children aged 7–24 months in Phnom Penh (urban) and Prey Veng (rural). Four PCFPs were included: a commercial brand, a social‐commercial brand, a worldwide distributed fortified complementary food aid product (CSB++) and an experimental fortified rice‐and‐fish‐based PCFP developed in Cambodia (WF‐L). Sensory analysis was conducted for all products, stated WTP was assessed for three products (excluding CSB++) and actual WTP experiment was conducted on WF‐L only. Our results show that overall, WF‐L was preferred by the rural participants over food aid CSB++. Further improvements in the organoleptic qualities of WF‐L should focus on consistency and taste. The participants were, on average, willing to pay 1,667 Cambodian riel (KHR, $0.4) and 1,192 KHR ($0.3) in urban and rural settings, respectively, for 35 g of WF‐L. We also found that despite being nutritionally inadequate, most participants considered homemade porridge to be healthier, more practical and preferred by the children. Therefore improving the quality of homemade foods merits urgent consideration. When applying PCFP in nutrition programmes as a supplementary option to homemade complementary foods, locally produced products could be a more viable supplementary option than global food aid
