DISTRIBUTION OF NON-MALIGNANT HEMATOLOGICAL DISORDERS BY SEX, AGE GROUPS AND TYPE OF DISEASE BASED ON BONE MARROW ASPIRATION IN POPULATION OF KHYBER PAKHTUNKHWA, PAKISTAN

Background: The distribution of non-malignant hematological disorder varies across globe by sex, age groups and type of disease. The objectives of this study were to determine distribution of non-malignant hematological disorders by sex, age groups and type of disease based on bone marrow aspiration in population of Khyber Pakhtunkhwa, Pakistan. Materials and Methods: This cross-sectional study was conducted in Department of Pathology, Khyber Teaching Hospital, Peshawar, Pakistan from Jan.-Dec. 2014. 116 cases with non-malignant hematogical disorders were selected. Sex, age groups and type of disease were analyzed by count and percentage with confidence intervals for proportions. Chi-square goodness-of-fit test was used to testify two hypotheses. Results: Out of 116 cases, 63(54.31%, 80%CI 48.38-60.24) were men and 53(45.69%, 80% CI 39.76-51.62) women. Age groups wise; 31(26.72%, 80%CI 21.46-31.99) were child (≤17 years), 57(49.14%, 80%CI 43.19-55.09) young adult (18-35 years), 19(16.38%, 80%CI 11.98-20.78) middle-aged adults (36-55 years) and nine (7.76%, 80%CI 4.57-10.94) older adults (≥56 years). Frequency of type of disease was; hemolytic anemia 17(14.66%, 80%CI 10.45-18.86), megaloblastic anemia 16(13.79%, 80%CI 9.69-17.9), bone marrow hypoplasia 14(12.07%, 80%CI 8.19-15.95), iron deficiency anemia 13(11.21%, 80%CI 7.45-14.96), mixed deficiency anemia 9(7.76%, 80%CI 4.57-10.94), ITP 9(7.76%, 80%CI 4.57-10.94), aplastic anemia 8(6.89%, 80%CI 3.88-9.91), bi-liniage cytopenia 7(6.03%, 80%CI 3.2-8.87), erythroid hyperplasia 3(2.59%, 80%CI .7-4.47) and malaria 2(1.72%, 80%CI 0.18-3.27). In 18(15.52%, 80%CI 11.21-19.83) cases the bone marrow was diluted. Null hypothesis for distribution of sex (p=.3532) was accepted while that for age groups was rejected (p=
