Soil-transmitted helminths (STH) infections are a major public health problem that affects more than two billion people around the world. Iron deficiency anemia is the most prevalent hematologic disorder in school-going children. Therefore the aims were the study to assess the correlation between helminthes infection and nutritional status among school-going children in the rural areas of Mardan Khyber Pakhtunkhwa Pakistan. A total of 300 samples were taken from the school-going children. The samples were taken through a cross-section survey, physical examination, lab investigations, and clinical examination from both the helminthic and anemic children. The current research work shows that 1 of 3rd of the school-going children who had signs and symptoms of iron deficiency anemia were affected with iron deficiency anemia the ages of 4 to 7 years 40(40%), 7 to 10 years 35(35%) and 10 to 13 years 25(25%) respectively. severe anemia was rare at 10%, moderate anemia at 25% led by the mild type of anemia with a high percentage of 65% based on Hb level. lower class families were more affected by iron deficiency anemia with 60%, children of middle class were less affected by anemia with 35% while children of upper class families were much less affected by anemia which may be due to the socioeconomic state of the family. Therefore it is recommended that iron supplementation, nutrition education and helminthic awareness programs should be conducted in schools.
