Child of Urban Poverty Iron Project (CUPIP) - A Pilot Study

This is a pilot study in a single-centre, using a single-blind, two-parallel group, randomized trial conducted amongst children aged 6 months to 5 years residing at PPR Lembah Subang, located in the state of Selangor, Malaysia between October 2019 and February 2020 (4 months). The participants were randomly assigned in a 3:2 treatment-to-control allocation to receive, in addition to the baseline deworming treatment, either daily micronutrient packets for 4 months (intervention arm) or no micronutrient supplementation (control group). This residency area comprises a local population with mixed ethnic makeup and poor socioeconomic status (majority are B40). We distributed flyers, posters, and leaflets with the help of the community mothers in PPR communities to encourage participation. Registration, informed consent and anthropometric measurements, dietary logs and blood drawn for iron status were taken prior to randomization. All children received a baseline deworming treatment at this point. The treatment group received baseline deworming medications, a 4-month supply of daily micronutrient supplementation and a compliance monitoring log. The control group only received similar baseline deworming medications without any daily micronutrient supplementation. Only the research investigators and outcome assessors were masked to the treatment status whilst the participants and interventionists research investigators were aware of the assigned intervention. Primary endpoints assessed in this study are changes in serum ferritin and hemoglobin levels at 0 and 4 months after interventions. The secondary endpoints are changes in age-and-sex standardized height and weight percentile scores at 0 and 4 months after micronutrient supplementation.
