Thalassemia and hemoglobinopathy prevalence in a community-based sample in Sylhet, Bangladesh.

We found a high prevalence of alpha thalassemia among both women and children in rural Sylhet, Bangladesh-higher than all other identified hemoglobinopathies combined. Community-based estimates of alpha thalassemia prevalence in Bangladesh are scarce, yet our findings suggest that alpha thalassemia may comprise the majority of inherited blood disorders in some regions of the country. We recommend that future research on inherited blood disorders in Bangladesh include estimates of alpha thalassemia in their reporting for public health awareness and to facilitate couples  counseling.
