Adherence to home fortification with micronutrient powders in Kenyan pre-school children: self-reporting and sachet counts compared to an electronic monitoring device.

摘要: The efficacy of home fortification with iron-containing micronutrient powders varies between trials, perhaps in part due to population differences adherence. We aimed assess what extent adherence measured by sachet count or self-reporting forms is agreement electronic device. In addition, we explored how each method assessment (electronic device, count, forms) associated haemoglobin concentration at the end intervention; and baseline factors were as Three hundred thirty-eight rural Kenyan children aged 12-36 months randomly allocated three treatment arms (home two different iron formulations placebo). Home fortificants administered daily parents guardians over a 30 day-intervention period. assessed using an device that stores provides information time day opening container was used store sachets child’s residence. counts. also intervention. Adherence, defined having received least 24 (≥ 80%), during 30-day intervention period attained only 60.6% corresponding values higher when self-report (83.9%; difference: 23.3%, 95% CI: 18.8% 27.8%) (86.3%; 25.7%, 21.0% 30.4%).
