Reproductive Health Issues for Adults with a Common Genomic Disorder: 22q11.2 Deletion Syndrome

22q11.2 deletion syndrome (22q11.2DS) is the most common microdeletion syndrome in humans. Survival to reproductive age and beyond is now the norm. Several manifestations of this syndrome, such as congenital cardiac disease and neuropsychiatric disorders, may increase risk for adverse pregnancy outcomes in the general population. However, there are limited data on reproductive health in 22q11.2DS. We performed a retrospective chart review for 158 adults with 22q11.2DS (75 male, 83 female; mean age 34.3 years) and extracted key variables relevant to pregnancy and reproductive health. We present four illustrative cases as brief vignettes. There were 25 adults (21 > age 35 years; 21 female) with a history of one or more pregnancies. Outcomes for women with 22q11.2DS, compared with expectations for the general population, showed a significantly elevated prevalence of small for gestational age liveborn offspring (p < 0.001), associated mainly with infants with 22q11.2DS. Stillbirths also showed elevated prevalence (p < 0.05). Not all observed adverse events appeared to be attributable to transmission of the 22q11.2 deletion. Recurring issues relevant to reproductive health in 22q11.2DS included the potential impact of maternal morbidities, inadequate social support, unsafe sexual practices, and delayed diagnosis of 22q11.2DS and/or lack of genetic counseling. These preliminary results emphasize the importance of early diagnosis and long term follow-up that could help facilitate genetic counseling for men and women with 22q11.2DS. We propose initial recommendations for pre-conception management, educational strategies, prenatal planning, and preparation for possible high-risk pregnancy and/or delivery.

Illegal yet developmentally normative: a descriptive analysis of young, urban adolescents' dating and sexual behaviour in Cape Town, South Africa

BACKGROUND

In South Africa, it is illegal for adolescents under age 16 years to engage in any sexual behaviour whether kissing, petting, or penetrative sex, regardless of consent. This cross-sectional study investigated the extent to which young adolescents engage in various sexual behaviours and the associations between dating status and sexual behaviours.

METHOD

Grade 8 adolescents (N = 474, ages 12-15 years, mean = 14.14 years) recruited from Cape Town schools completed surveys providing information about their sociodemographic backgrounds, dating experience, sexual behaviour, and substance use.

RESULTS

Lower hierarchy sexual behaviours, such as kissing (71.4% of girls; 88.4% of boys), were more common than oral (3.9% of girls; 13.8% of boys), vaginal (9.3% of girls; 30.0% of boys), or anal (1.4% of girls; 10.5% of boys) sex. Currently dating girls and boys were more likely to engage in sexual behaviours including several risk behaviours in comparison to their currently non-dating counterparts. These risk behaviours included penetrative sex (21.1% of dating vs. 4.5% of non-dating girls; 49.4% of dating vs. 20.2% of non-dating boys), sex with co-occurring substance use (22.2% of dating vs. 0 non-dating girls; 32.1% of dating vs. 40% of non-dating boys), and no contraceptive use (26.1% of sexually experienced girls; 44.4% of sexually experienced boys). Among girls, there were significant associations between ever having penetrative sex and SES (OR = 2.592, p = 0.017) and never dating (OR = 0.330, p = 0.016). Among boys, there were significant associations between ever having penetrative sex and never dating (OR = 0.162, p = 0.008). Although the currently dating group of young adolescents appear to be a precocious group in terms of risk behaviour relative to the currently non-dating group, teenagers in both groups had experience in the full range of sexual behaviours.

CONCLUSIONS

Many young adolescents are engaging in a variety of sexual behaviours ranging from kissing and touching to intercourse. Of particular concern are those engaging in risky sexual behaviour. These findings indicate that adolescents need to be prepared for sexual negotiation and decision-making from an early age through comprehensive and accessible education and health services; sections of current legislation may be a barrier to adopting such policies and practices.
