Consanguineous marriages, premarital screening, and genetic testing: a survey among Saudi university students

Background

Marriage among cousins or close relatives, i.e., consanguinity, is prevalent in many parts of the world, especially the Muslim world. Across civilizations, cultural norms, religious beliefs, and economic factors affect consanguineous marriages (CMs); however, such marriages have social, genetic, and health repercussions. The present study investigated the university students' attitudes regarding CMs and factors influencing their attitudes at King Abdulaziz University (KAU), Jeddah, Kingdom of Saudi Arabia (KSA).

Methods

This cross-sectional prospective study was conducted at KAU Jeddah in 2023. The questionnaire was distributed via electronic media (Emails, Facebook Messenger & WhatsApp). The convenience sampling technique was used to select participants, and descriptive and inferential statistics were used to analyze the data on SPSS-26.

Results

A total of 1707 university students were part of the study (females, 1,198, 70.2%; males, 509, 29.8%). Almost half of the participants, 819 (48.0%), had parents with CMs. Most of the participants, 1,391 (81.5%), had CMs in the family. Half of the participants disagreed that parents consider marriage stable due to high compatibility and the same social relationship before and after marriage. About one-third of respondents said parents believe family marriage transmits cultural values and continuity and keeps wealth in the family. More than three-fourths of the participants stated that if marriage is arranged with first cousins, they will opt for genetic analysis (82.5%) and premarital counseling (85.2%). The personal attitudes of females (p < 0.001), undergraduate (p = 0.02), and health sciences students (p = 0.02) were more positive than their counterparts. Males (OR = 0.41; p < 0.001) and non-health sciences students (OR = 0.68; p = 0.01) were less likely to have significant positive attitudes than their counterparts. Among participants who had CM parents, males (OR = 0.397; p < 0.001) and non-health sciences students (OR = 0.60; p = 0.01) and urban residents (OR = 0.59; p = 0.01) had significantly lower odds of having a positive attitude than their counterparts.

Conclusion

The practice of CMs is still prevalent in Saudi culture, with almost half of the participants having CM parents and the majority reporting these marriages in their families. Personal attitudes toward CMs were extremely positive. Most students prefer genetic testing and premarital counseling if marrying first cousins. Gender, faculty, parental income, and educational background influenced participants' attitudes.

Diabetes Mellitus Knowledge, Attitudes, Preventive Practices and Associated Factors Among a Sample of Adult Non-Diabetic Saudi Residents

Purpose

To assess the diabetes mellitus (DM) knowledge, attitudes, preventive practices, and associated factors among a sample of adult non-diabetic Saudi residents.

Methods

The present survey was conducted in April-June 2022. People from the general population were invited to participate in the study, and the data were collected using a validated questionnaire.

Results

A total of 1207 non-diabetic subjects participated in the study [females 798(66.1%) and males 409(33.9%)], and the response rate was 80% (1207/1500). Two-thirds (66.86%) of non-diabetic adult community members had good knowledge of DM, 47.8% had positive attitudes, and 62.14% maintained a healthy lifestyle to avoid DM. There was a family history of DM in more than half of the subjects 723(59.9%). Participants who had a direct relative with diabetes scored higher on the knowledge question than those who did not (p<0.001). Practice questions responses for preventing DM showed that about 459(38%) were using fatty food less frequently, and only 338(28%) and 153(12.7%) were doing physical activities 30-60 minutes per day frequently and very frequently, respectively. Most participants were smoking tobacco, 890(73.7%), and getting checked their BP, 704(58.3%), very frequently. The participants with a master's and Ph.D. degree were likelier to have positive attitudes and good practices than students. Individuals with a history of DM in their families were 2.10 times (OR=2.10, p<0.001), 1.95 times (OR=1.95, p<0.001), and 2.03 times (OR=2.03, p<0.001) more likely to be knowledgeable, had positive attitudes and good practices than those with no DM in their family, respectively.

Conclusion

 Over half of the individuals possessed a positive mindset, adequate knowledge, and good practicing behavior for preventing DM. Having Master's and Ph.D. degrees and a family history of DM were associated with a positive attitude and good practices. There is a need to expand community awareness campaigns utilizing social media channels.
