Premarital hemoglobinopathy screening program results of a province in the Black Sea region of Turkey: three years' experience.

OBJECTIVES

Hemoglobinopathies are a global public health problem with high mortality and morbidity and very expensive treatment. Disease can be reduced and prevented with hemoglobinopathy screening tests. It is possible to identify carriers with the hemoglobinopathy screening program applied in many countries of the world and in Turkey. This study aims to evaluate the results of the national premarital hemoglobinopathy screening program carried out in primary healthcare institutions.

METHODS

The research is of epidemiological and cross-sectional type. Electrophoresis results examined within the scope of the premarital hemoglobinopathy screening program in Samsun between 1 January 2019 and 31 December 2021 were evaluated retrospectively. Age, gender, year of screening, and hemoglobinopathy screening results were obtained from the records. In the statistical analysis of the data,  < 0.05 was accepted.

RESULTS

The median age of 52,338 people screened under the hemoglobinopathy screening program was 29.0 (16.0-86.0) years. About 54.1% ( = 28,309) of those who were screened were female, and it was found that the least screening was done in 2020 ( = 15,765 (30.1%)). As a result of the screening, the frequency of the β-thalassemia (β-thal) trait was 1.37% ( = 676), the frequency of the abnormal HbS was 0.04% ( = 20). The frequency of β-thal trait was statistically significantly higher in 2020 (1.5%) compared to other years ( = 0.029). When the results were analyzed by gender, the rate of women with abnormal HbS (3.7%) was significantly higher than the others ( = 0.017).

CONCLUSIONS

This study presents the results of the national hemoglobinopathy screening program in Northern Turkey and the β-thal and the abnormal HbS rates were found to be low. The data obtained will be useful in monitoring hemoglobinopathy disorders and evaluating the current program's effectiveness in the future. It will allow decision-makers to implement policy changes and prioritize new programs.
