<p>Purpose: To determine the prevalence of anemia among tribal communities of Burliyar and to improve medication adherence to iron by implementing a daily monitoring system by the community health ambassadors (CHA) and to identify any other cause of anemia in patients who do not improve with the intervention.

The cut off to define anemia in adults was Hb &lt; 13 gm/dl in males and &lt; 12 gm/dl in females. Based on this criterion, we had 131 (71%) participants with anemia of which 74 (56%) were females and 57 (44%) were males. Among these, 32 (24%) participants were children &lt; 14 years of age. There was distribution of iron supplements for 100 days along with iron-rich ration to 110 participants, which was monitored daily by the CHA and the prevalence of anemia reduced from 71.2 to 61.8%.

摘要

Purpose: To determine the prevalence of anemia among tribal communities of Burliyar and to improve medication adherence to iron by implementing a daily monitoring system by the community health ambassadors (CHA) and to identify any other cause of anemia in patients who do not improve with the intervention. Methods: This was a prospective cross-sectional community-based anemia study done from November 2023 to May 2024 in the tribal hamlets in Burliyar, Nilgiris, with a shifting population averaging 230. Results: A baseline hemoglobin screening was done on 184 participants using the Accusure Hb101 system with capillary blood. The cut off to define anemia in adults was Hb < 13 gm/dl in males and < 12 gm/dl in females. Based on this criterion, we had 131 (71%) participants with anemia of which 74 (56%) were females and 57 (44%) were males. Among these, 32 (24%) participants were children < 14 years of age. There was distribution of iron supplements for 100 days along with iron-rich ration to 110 participants, which was monitored daily by the CHA and the prevalence of anemia reduced from 71.2 to 61.8%. An additional 29 participants were added into the study during our monthly camps. Out of the 139 participants, 36 (26%) were suspected to have hemoglobinopathy. Of these, 30 participants underwent High Performance Liquid Chromatography (HPLC) and 7 among them were identified to have sickle cell trait and 1 had sickle cell disease. The remaining 22 underwent molecular testing and all were identified to have homozygous alpha 3.7 deletion (-α3.7/-α3.7). Conclusion: Targeted intervention and careful monitoring help to reduce the burden of anemia in a community. Although iron deficiency anemia is the most common form of anemia, a quarter of the patient population in this study had hemoglobinopathy– predominantly alpha thalassemia.
