To compare the response towards prenatal diagnosis (PND) of b-thalassaemia, in individuals who had not received genetic counselling and a genetically counselled population.
Cross-sectional survey.
Department of Haematology, Armed Forces Institute of Pathology (AFIP), Rawalpindi, from March 2009 to December 2010.
Using non-probability consecutive sampling, a total of 176 individuals having thalassaemic children, were interviewed regarding PND of thalassaemia, by using a structured questionnaire. Forty two individuals were taken as controls as they had received genetic counselling for PND, whereas the remaining 134 were taken as cases. Responses towards PND were compared using chi-square test. Odds ratio was also calculated for subsequent PND utilization.
Seventy (52.2%) cases and 42 (100%) controls were aware of the availability of PND in Pakistan. This difference in awareness was statistically significant (p < 0.001). In the controls, 40 (95.3%) individuals were aware of the appropriate timing of the test, in contrast to 52 (39%) cases (p < 0.001). PND was used in subsequent pregnancies by 50 (37.3%) cases and 32 (80%) controls (p < 0.001). The calculated odds ratio for subsequent PND utilization was 5.37.
The study reflects a very positive attitude of genetically counselled thalassaemia affected families towards PND. For better utilization of PND, genetic counselling services should be available at all health strata.
