Abstract
Background: Hematological parameters are vital indicators of health, influenced by demographic factors.
Objective: This study aimed to investigate the association between age and gender with hematological and hemostatic parameters in a cohort of Yemeni university students.
Methods: A cross-sectional study was conducted on 100 apparently healthy students. Data on age and gender were collected via questionnaire. Venous blood was drawn for Complete Blood Count (CBC), Prothrombin Time (PT), and Partial Thromboplastin Time (PTT) analysis using automated analyzers. Statistical analysis was performed using SPSS.
Results: Significant gender-based disparities were observed. Females exhibited a markedly higher prevalence of abnormal hemoglobin (Hb) levels (58.1%, p=0.0001) compared to males (3.5%). Abnormalities in red blood cell indices (RBCs, MCHC) and platelet (PLT) count were also more common in females, though not always statistically significant. Regarding age, the 18-21 years group showed the highest prevalence of abnormalities suggestive of nutritional deficiencies, specifically in Mean Corpuscular Volume (MCV) (75.9%) and Mean Corpuscular Hemoglobin (MCH) (82.8%). On the other hand, we found that a prolonged APTT was most common in the small group of participants aged 26-29 years (88.9%, n = 9).
Conclusion: Gender significantly influences hematological status, with females showing a higher susceptibility to anemia. Age also affects certain hematological indicators, as mild coagulation changes may emerge in the late twenties, while younger individuals are more prone to nutritional deficiencies. Regular screening and targeted nutritional interventions are recommended for these at-risk populations.
