Keywords: Premarital Screening Attitudes Hemoglobinopathies

Background: A compulsory national premarital screening (PMS) program for hereditary hemoglobinopathies was established in the Kingdom of Saudi Arabia (KSA) in February 2004. Termination of pregnancy of affected fetuses is not widely acceptable. Many couples decide to get married regardless of the result. A trend towards coercive interference with this decision is emerging. Objectives: To examine the attitude of young educated individuals regarding the national PMS program and its implementation. Methods: Eight hundred university students (aged 18–29) filled in a self-administered structured questionnaire. Data were analyzed using the EPI Info Statistical Package version 6. A P-value <0.05 was considered significant. Results: Most students favor the PMS program but there were concerns regarding mandating the testing and interference with individual decision making. Significantly more women favored testing and coercive interference with the decision to marry. Conclusions: Further public education and wide spread genetic counseling prior to testing is essential for the success of the program. Screening singles on admission to university prior to any commitment may be preferable than screening immediately before the marriage certificate is issued. © 2010 Elsevier Ireland Ltd.

1. Introduction

study was conducted in The Makkah Province, in the City of Jeddah, on the Western Coast of Saudi Arabia. Jeddah is a modern urban cosmopolitan city with a population of over 3.4 million people. It is the second largest city in the Kingdom and its commercial capital [10]. King Abdulaziz University is the major university in the city with approximately 40,000 students, many who come from neighboring cities and villages. Countries like Bahrain, Iran and Cyprus have introduced premarital screening for hemoglobinopathies and proved the effectiveness of such a program in decreasing the incidence of the diseases tested for [11–13]. A compulsory national premarital screening (PMS) program for SCD and thalasemia was established in KSA in February 2004. The result is reported as either compatible (when neither or only one partner is a carrier for SCD or beta-thalasemia) or incompatible when both members

The hereditary hemoglobinopathies, sickle cell disease (SCD) and thalassemia are the most common genetic disorders in the Kingdom of Saudi Arabia (KSA) and Gulf region [1]. The carrier rate for SCD exceeds 25% of the population in some Saudi cities [2–5]. The population of the region is characterized by large family size, advanced maternal and paternal ages and a high level of inbreeding with consanguinity rates in the range of 25–60% [2,1,6–8]. KSA is a large country with a population of 25 million people. It is divided into 5 main provinces [9]. This

are carriers for either or both disorders. The decision to marry is left to the couple [14,15]. Prenatal diagnosis and termination of pregnancy are not offered routinely to carrier couples even though a 1990 ruling allows termination of pregnancy in the first 120 days after conception if the fetus is shown beyond doubt to be affected with a severe disorder that is not amenable to treatment [15,1,16]. Termination of pregnancy of affected fetuses is not very popular in the region [17], although it may be starting to gain acceptability [19]. Many couples decide to go ahead with the marriage despite the result being incompatible [2]. This may be due to lack of understanding or ineffective genetic counseling. We noted a recent trend favoring coercive interference with marriage for the so-called “genetically incompatible” couples in the media with some influential figures advocating this. Evidence for this trend has also been supported by some recent studies [19]. The effectiveness of carrier screening programs depends largely on the knowledge and attitudes of the target population. In a previous study we looked at the degree of knowledge regarding genetic disorders and the national PMS program in an important subgroup of the population (young university undergraduate men and women in the city of Jeddah). We showed that despite a reasonable level of knowledge regarding genetic disorders in general, there was a lack of appropriate knowledge regarding the national PMS program [20]. In this current study, we aim to explore another important determinant of success which is the attitude of this target group toward implementation of testing and identify the reasons for ignoring the test results. Previous studies from KSA revealed an overall favorable attitude towards the National PMS program [21,22,15,16,19], but with variable reports regarding the level of knowledge. KSA is a vast country (population > 22 million of which Saudis make up approximately 17 million). It is divided into 5 major regions. These regions differ considerably in ethnic background in addition to some cultural and social differences that are expected to affect attitudes. The Western Region of the Kingdom is considered to harbor the most heterogeneous population among Saudis and has several ethnic and cultural characteristics. To our knowledge, this is the first study to be conducted in the Western Region of the Kingdom, and to look at specific factors (gender, area of upbringing and type of education) affecting the attitudes. Identifying these factors is very important for putting forth recommendations to increase the success rate of the program. 2. Methods A stratified random sampling was conducted among the students of King Abdulaziz University (KAU) in Jeddah, western Saudi Arabia (KSA), during January 2006. A representative sample for each college in the university was interviewed. The minimum acceptable sample size was selected according to the actual number of students in each college and was calculated using the EPI Info statistical package, version 6. Attitudes of the students’ sample were explored using a structured questionnaire designed by the authors. The questionnaires were distributed among the

various colleges according to the percentage of students in each college (Table 1). A pretest pilot study was conducted on a sample of 54 students. Questions that seemed ambiguous were then modified. The students who answered the questionnaire in the pilot study were excluded from the final study. All regular undergraduate male and female students in the various colleges of KAU selected by random sampling and willing to participate – apart from those in the pilot group – were included in the study. A self-administered questionnaire was distributed to a sample of 800 students (of which 400 were men) who answered it under the direct supervision of the investigators. The questionnaires were distributed equally among males and females since each of them represents 50% of the university population. The questionnaires were distributed among the various colleges according to the percentage of students in each college. The questionnaire was divided into two main parts. Part one recorded the sociodemographic data and personal history of hereditary diseases and premarital screening among the students. The questions concerning attitudes were graded using the Likert scale which consists of 5 points. The 1st point is strongly agree and the 5th point is strongly disagree. Finally a space was left for further comments. Ethical approval was obtained from the local Research Ethics Committee. Participating students were guaranteed full confidentiality and privacy. The team members did not check the questionnaire in front of the students. After completing the questionnaire and returning it, the students were given educational pamphlets containing appropriate information regarding the national PMS program. After collection, the data was entered into the computer and analyzed using the SPSS PC software package. Chi-squared test was used to test significance on compar-

ing subgroups. A P-value was considered significant if it was less than 0.05. 3. Results All of the 800 participating students were Saudi. The age range was 18–29, and the mean was 21.4 years. The demographics of the study group are summarized in Table 1. Of the married students, 60.7% had personally carried out the PMS. While 6.2% of all the students reported personally having hereditary disease, 34.9% reported having hereditary disease in one or more of their family members. Among these, the reported disorders were SCD (1.1%), thalassemia (0.4%), glucose-6-phosphate dehydrogenase deficiency (0.4%) and hemophilia (0.2%). The remainder considered diabetes mellitus (18.8%), or allergy (4.6%) as hereditary disorders. Regarding the area of origin, 64.6% of those who received the questionnaire and responded were raised in Jeddah, 7.4% in the southern region of the Kingdom, 7% in Makkah, 5.8% in Taif and 4.3% in Madinah, the latter three being neighboring cities. Regarding attitudes towards PMS, 95.9% of the students believe that the PMS is essential (74.2% strongly agree and 21.7% agree), 1.7% that it is not essential and 2.5% do not know. On being asked whether they believed that the PMS limits the spread of hereditary disease, 95% of the students believe it does (63.2% strongly agree and 31.8% agree), 3.3% do not know and 1.8% does not believe it does. There was no significant difference on comparing gender, colleges, area of origin, or presence of a family history of genetic disease (Table 2). 84.8% of the study group believes that the PMS should be mandatory (i.e. as a legal requirement prior to issue of a marriage license), while 12.8% believed that it should be optional and 2.4% do not know. Gender was the only factor that was significantly different among those who believed that the PMS should be mandatory versus those who do not, with more women in favor than men (Table 3). This sex difference was persistent even among the medical students (Table 3). On being asked whether they believed that marriage should not be allowed among couples with a positive result, 37.1% of the

students strongly agreed, 26.1% agreed, 12.7% disagreed, 5.8% strongly disagreed and 18.3% answered “don’t know”. More women (82.4%) believed the marriage should not be allowed than men (72.3%) (P value = 0.002). No other factors including family history, medical background, or place of origin differed in a statistically significant manner (Table 2).

4. Discussion Genetic disorders cause a significant burden in Saudi Arabia, and hemoglobinopathies make up a substantial proportion of these genetic disorders [1,3]. Screening for the carrier status for SCD and B-thalassemia may help in decreasing the occurrence. The local attitudes towards the screening program are an important determinant of its success rate. In a previous study we asked participants about the specifics of the PMS including the interpretation of the tests results. When breaking the group down, medical students consistently had more knowledge than non-medical students and women more knowledge than men [20]. In this study we found that women also had stronger attitudes toward the implementation of testing with a significantly higher number of female respondents believing that the PMS should be mandatory and that marriage should not be allowed between two carriers of the same disorder. We speculate that this may reflect the belief that women in many parts of this society may bear more of the burden of a handicapped or chronically ill child. In addition, they have less opportunity to a “second chance” than men. It may be argued that this study was limited to university students rather than the general population. This was intended by the author to look at gender, knowledge and ethnic differences among a young and educated group. Another limitation may be that the study was conducted in one university of the Makkah region. However this is currently the largest university in the region and is made up of a heterogeneous population from various cities and districts. There was no significant difference in knowledge or attitude among those raised in Jeddah compared to those raised in the surrounding less industrialized cities, towns and villages. The role of education at university level may therefore override any cultural or familial differences. On exploring attitudes towards implementation, in general, attitudes were positive and favored the PMS. Almost all the students (95.9%) believed the PMS was essential and (95%) that it can limit the spread of disease. However, when being asked whether the PMS should be mandatory, although still the majority, a fewer number agreed (84.8%) raising concerns about individual autonomy. Other studies done in the Kingdom have shown even less acceptance rate of having the PMS as a mandatory requirement for marriage licensing [15,21]. Even less individuals in our study (63.2%) agreed to legal interference with issuing of a marriage license in case of positive results. There has been some controversy among local authorities and professionals in the field on whether or not there should be legal intervention to prevent marriage among

35

carriers. In this study, just above 60% of the sample agreed that marriage should be prevented. Although this represents the majority there is a significant proportion that does not agree including a subgroup that strongly disagrees. This group must be kept in the mind of policy makers. In a study conducted among male health science students in the South of the Kingdom, less than one fifth of the sample agreed to regulations against continuation of marriage in the case of the PMS results [21]. Rather than preventing the marriage forcefully which may cause significant social and individual harm, we would be better off looking at the reasons why couples often decide to marry despite both members being carriers of the same disorder. One very important factor we believe is the timing of the test. The PMS is usually done as a formality and as a final step in the preparation for marriage. An unexpected result may therefore need to be ignored by the couple or their families for various cultural, social, emotional and financial reasons. This however can be prevented. A well established premarital genetic testing program, The Dor Yeshorim initiative founded in the 1980s had proven its success [23]. In this program, individuals are offered testing in their teenage years for certain genetic disorders. Mass tests are usually carried out in educational institutes following public discussion and education. This program carries the additional advantage that it does not review individual results. Instead, young individuals are tested early in adulthood, the results are not released but the individuals are given confidential identification numbers. Later when they decide to marry, potential spouses are matched for genetic compatibility but still no specific information regarding individual carrier status is given. Thus the compatibility can be known prior to engagement yet avoiding the burden of genotype knowledge in the absence of practical implications. Such a model is ideal for societies where arranged marriage is a common practice and termination of pregnancy is highly undesirable. In the absence of such a system, we suggest that genetic counseling followed by testing be done in group sessions in the early college years or on leaving school with parental consent for those under 18 years of age. It would be essential however to have counseling appropriate to each individual’s age and understanding so as to prevent unwanted complications of genetic testing such as anxiety, social stigmatization and discrimination. Genetic counseling can be followed by testing if the individual decides to do so. PMS would remain mandatory prior to marriage for those who haven’t done it at the early stage. One limitation is the scarcity of trained counselors. This could be partially overcome by training courses specific to this issue, including issuing certificates on completion of training and simulated examination. Only individuals certified in counseling for PMS would then be able to do so. Prior to interference with marriage decisions, we need to look back and reflect on our practice so far with continuous audit and review. Also, improving the population knowledge will improve their understanding and cooperation and can decrease the number of marriages among carriers without resorting to legal restrictions. Coercive marriage programs trigger

many ethical concerns on the grounds of human rights, control, oppression and eugenics [24]. They may lead to public rebellion or seeking marriage licensing abroad [25]. On the contrary, voluntary programs have led to a significant decline in the number of children born with certain disorders. One example is the drop of incidence of TaySachs disease in the Jewish communities of the USA [26]. Public Education regarding these genetic disorders and the implication of testing is essential for the success of the premarital program [10,21]. In addition to formal counseling at the time of testing, mass education especially at high school and university levels can play a major role in increasing the level of knowledge regarding PMS. It has also been suggested that education about PMS be included in the university curriculum [22]. Opportunistic counseling done by health professionals during general check-ups or other physician office visits may help in addition to educational pamphlets, targeted TV programs and advertisement. Perhaps education must start with those in the medical profession especially those in certain specialties such as family medicine or obstetrics and gynecology so they can play their role in the education process and be equipped to answer related questions.

5. Conclusions The majority of young adults favor the implementation of the National PMS program. This positive attitude is a strength for the success of the program. Recommendations to increase the success of this attempt are:

1. Changing the timing of the test to the early college/late school years rather than immediately prior to marriage. 2. Mandating genetic counseling by trained professionals prior to each test. 3. Make up for scarcity of genetic counseling professionals by: A. Group counseling sessions. B. Certified training courses in genetic counseling specific for PMS. 4. Widespread public education. In addition to the existing campaign stress must be put on: A. Education in high schools and universities. B. Opportunistic counseling by various health professionals who encounter prospective spouses. C. Education of related professionals such as family physicians and obstetricians regarding the National PMS program.

The success of PMS for hereditary hematologic disorders may lead to the inclusion of further prevalent disorders. Finally, the role of repeated audit with quality assurance guidelines cannot be overestimated. Studies similar to this one can help understand the deficiencies and take opportunity of the available strengths such as many students’ positive attitude and commitment towards the PMS.
