Background and Objectives
Blood donation plays a vital role in sustaining healthcare system. Donation rates can be influenced by the demographic characteristics of blood donors, Particularly age. Understanding age-related patterns of blood donation is essential for improving strategies to retain existing donors and recruit new donors. This study aimed to analyze the age distribution of blood donors and its impact on donation rates in Iran in the year 2022.
Materials and Methods
This ecological cross-sectional study utilized aggregated data from the Iranian Blood Transfusion Organization database, focusing on blood donation rates and age distribution across various provinces. The relationship between the proportion of blood donations within three age groups 18–35 years, 36–55 years, and over 55 years and the overall blood donation rate were examined using Pearson correlation and linear regression analysis. Statistical analysis were performed using STATA version 17, with a significance level set at ≤ 0.05.
Results
In 2022, blood donation rates across Iran’s 31 provinces varied from the lowest of 17.76 in 1000 population in Sistan and Baluchestan province to the highest of 39.78 per 1,000 population in Semnan Province. Overall, the age group 35-55 years had the highest share of blood donations (56.72%) and the age group over 55 years had the lowest share of blood donations (6.39%) in the countryThe results of the linear regression test showed a significant relationship between the age group of 36-55 years and the blood donation rate with a beta coefficient of 0.615 and a standardized beta coefficient of 0.388 (p=0.031). Conclusions
This study highlights the significant role of age distribution in shaping blood donation behavior. The findings indicate that the 36-55 age group as a key contributor to elevated blood donation rates across the country. These results can assist policymakers in designing targeted interventions to increase blood donation rates by understanding the behaviors of different age groups.
