Aims/Objectives: This study sought to determine the prevalence, morphological character- ization and associated socio-demographic factors of anemia among pregnant women attend- ing Kisugu Health Centre IV, Makindye Division, Kampala, in Uganda. Methods: This was a cross-sectional study that employed laboratory analysis of blood samples to determine hemoglobin concentration, and a structured questionnaire to obtain socio-demographic factors associated with anemia during pregnancy. Results: We enrolled 345 pregnant women aged 15 to 43 years. The median, interquartile range, and mean Hb levels were 8.1g/dL, 6.4 ± 2.1g/dL and 7.9g/dL, respectively. There were 89 participants whose Hb levels were indicative of anemia, giving anemia prevalence of 25.8% (95% confidence interval: 21.6–29.8). Of these, 25 (28.1%) had mild anemia, 46 (51.7%) had moderate anemia, while 18 (20.2%) had severe anemia. Thin blood film examination showed normocytic-hypochromic (75.3%), then microcytic-hypochromic (21.6%), and macrocytic- hypochromic red blood cells (3.4%). The socio-demographic factors of gestational age, parity, and mother’s occupation were significantly associated with the risk of anemia (p< 0.05). Conclusion: We report a high prevalence of anemia among pregnant women; with a majority of hypochromic-microcytic anemia. This may necessitate more anemia awareness and it requires institution of nutritional interventions to avert fetal-maternal complications

Aim/objective: The aim of this study was to determine the prevalence, severity, morphological characterization, and the associated factors of anemia among children under the age of 5 years at St. Mary’s Hospital Lacor, Gulu District, Northern Uganda. Materials and methods: A structured questionnaire was administered to each participant’s parent/caregiver to collect data on sociodemographic factors, feeding pattern, and history of chronic illness. Hemoglobin (Hb) estimation was performed using a HemoCue 201 + analyzer. Peripheral thin and thick blood films were made from venous blood and stained with Giemsa to morphologically characterize red blood cells (RBCs) and investigate hemoparasites, respectively. We collected and examined stool specimens from each participant using wet preparations and formol–ether concentration technique for intestinal parasites. Descriptive statistics was used to describe study participants and to determine the prevalence of anemia. Logistic regression analysis was done to determine the factors associated with acquiring anemia at a P-value≤ 0.05. Results: The study enrolled 343 children below the age of 5 years. Of these, 62.7% (N=215) were females. The IQR, median, and mean Hb levels were 5.1±3.2 g/dL, 8.2 g/dL, and 7.9 g/dL, respectively. Overall, 160 (46.6%, 95% CI: 42.1–51.46) children had anemia. The magnitude of severe, moderate, and mild anemia was 11.9%, 58.8%, and 29.4%, respectively. Morphologic characterization of anemia revealed hypochromic-microcytic (65.4%, N=106), hypochromic- macrocytic (15.4%, N=25), and normochromic-microcytic (19.1%, N=31) anemia. Factors associated with anemia were parasitic infestation, history of chronic disease, lack of complementary foods, complementary feeding for not more than twice a month, and households’ with annual income less than 200,000 Ugandan Shillings. Conclusion: We report the high prevalence of anemia among children below 5 years of age in Gulu District, Northern Uganda. Thus, strategies geared at addressing the etiologic causes (such as nutrient deficiency and parasitic infections) are key to reduce it in the region.
To test or not: occurrence of sickle cell trait and assessment of the awareness toward its screening among patients attending Magale Health Center IV, Namisindwa District, Eastern Uganda

Purpose: To evaluate the occurrence of sickle cell trait (SCT), assess patient awareness and evaluate the performance of a sickle cell hemoglobin-S (dithionate-qualitative solubility) point- of-care test among patients seeking care at Magale Health Center IV, Namisindwa District, Eastern Uganda. Materials and methods: We conducted a cross-sectional study, in which we consecutively enrolled participants aged ≥18 years at Magale Health Center IV. Four millilitres of EDTA blood were collected by venipuncture and screened for SCT using solubility testing, and confirmed with hemoglobin (Hb) electrophoresis at Central Public Health Laboratory (CPHL), Kampala, Uganda. A structured questionnaire was used to assess participants’ awareness of SCT. Data were presented as proportion, and measurements of diagnostic test performance were calculated. Results: We enrolled 242 participants, of these 58.7% (N = 142) were females. Their mean age was 26.4 years (range 18–49). Of the 242 participants, 11, who represent 4.5% (95% CI: 3.3–5.9), tested positive. The sensitivity, specificity, positive predictive value and negative predictive value of the rapid sickle cell test were 63.64%, 100%, 100% and 98.30%, respectively. There was a knowledge gap regarding sickle cell awareness. Conclusion: The occurrence of SCT was high, and the point-of-care test showed high diagnostic reliability. The risk of SCT is associated with genetic predisposition as indicated by Hb electrophoresis. Community sensitization is key to avert the associated risk of Hb defects.
