Rapid acceptability and adherence testing of a lipid-based nutrient supplement and a micronutrient powder among refugee children and pregnant and lactating women in Algeria

Abstract

Objective To assess the acceptability and adherence to daily doses of lipid-based nutrient supplement (LNS) among children and micronutrient powder (MNP) among children and pregnant and lactating women. Design Household interviews and sachet counting were conducted to measure acceptability and adherence, 15 and 30 d after product distribution. Qualitative information on product acceptability was collected using focus group discussions. Setting Saharawi refugee camps, Algeria, August-October 2009. Subjects LNS was distributed to 123 children aged 6-35 months (LNS-C), and MNP to 112 children aged 36-59 months (MNP-C) and 119 pregnant or lactating women (MNP-W). Results At the end of the test 98·4 % of LNS-C, 90·4 % of MNP-C and 75·5 % of MNP-W participants reported that they liked the product (P<0·05). Other measures of acceptability did not differ. Median consumption of sachets was highest in the LNS-C group (P<0·001). 'Good' adherence to the daily regimen (consumption of 75-125 % of recommended dose) was 89·1 % in the LNS-C, compared with 57·0 % in the MNP-C and 65·8 % in the MNP-W groups (P<0·001). Qualitative findings supported the quantitative measures and guided selection of local product names, packaging designs, distribution mechanisms, and the design of the information campaign in the subsequent programme scale-up. Conclusions Acceptability, consumption and adherence were higher in participants receiving LNS compared with MNP. However, both products were found to be suitable when compared with predefined acceptability criteria. Acceptability studies are feasible and important in emergency nutrition programmes when the use of novel special nutritional products is considered.
