OBJECTIVE: Despite premarital screening, prenatal diagnosis and the option for voluntary termination of pregnancy, some Iranian couples continue a pregnancy with a fetus affected with beta-thalassaemia major (β-TM). We examined the reasons for this decision, to evaluate the sociocultural challenges these couples face. METHODS: A retrospective evaluation of medical records of all fetuses aborted was conducted to identify those with β-TM, to determine the frequency of β-TM births and to establish the number of couples with β-thalassaemia who declined prenatal diagnosis or a termination of pregnancy in this period. We investigated the reasons for declining these options. RESULTS: The birth prevalence of β-TM decreased from 39.38 to 2.68 in 100,000 live births from 2005 to 2010. Terminations of pregnancy for affected fetuses increased from 67 in 2005 to 135 in 2010. We identified eight couples as β-thalassaemia carriers who declined prenatal diagnosis or a termination of pregnancy. All but one couple already had a child with β-TM. The reasons for declining prenatal diagnosis were strong religious beliefs, superstition and faith in a supernatural solution in six couples. Economic and cultural factors, and previous termination of pregnancy were also mentioned as reasons by the other two couples. CONCLUSION: Although most of the couples had a β-TM child and related socioeconomic problems, their reasons for refusing prenatal diagnosis or termination remain a challenge for the healthcare system in Iran. Couple screening and educational programmes have effectively decreased the rates of refusal in at-risk couples in recent years.
