RESUMEN
Anemia and iron deficiency can cause detrimental effects on brain development, and continued iron deficiency anemia is known to interfere with development which results in a permanent delay in mental and Motor development. This study investigated the impact of anemia on physical development skills of under two years children in aceh besar district. A cross-sectional study design was applied to 102 under-two years children selected using cluster random sampling technique using village as cluster. A structured questionnaire to determine general characteristics such as maternal age, maternal education, maternal occupational, family income, number of family members and toddlers. Anemia status was assessed by Hemocue 201+ tool, and physical motor development such as gross and fine motor development skills were determined using Denver II instrument. Almost two- thirds of children were anemia, as assessed by blood hemoglobin levels of <11 g/dL, while 34.3% of them were experienced delay in either fine development or gross development skills. The prevalence of children with fine and gross motor development delay was higher in children with suffering from anemia (27.1% and 17.1%) than non-anemia, respectively (3.2% and 9.4%). There was significant association anemia status on fine motor development (r=0.291; p=0.003), while not significant to gross motor development (r=0.092; p=0.357). The prevalence of anemia in children 12-24 mo old was very high, and has an impact on motor development delays, so anemia prevention programs and motor stimulation intervention for under two years children are needed.
