Infertility treatments and cyanotic congenital heart defects among livebirths in the USA: findings from a contemporary cohort

STUDY QUESTION

Is there an elevated risk of cyanotic congenital heart defects (CCHD) among livebirths following infertility treatments?

SUMMARY ANSWER

In this population-based study of single livebirths, infertility treatment (either ART or non-ART) was associated with a higher prevalence of CCHD among livebirths.

WHAT IS KNOWN ALREADY

The use of infertility treatment has been on the rise over the past few decades. However, there are limited studies assessing the risk of major cardiac defects following infertility treatments.

STUDY DESIGN, SIZE, DURATION

A retrospective cohort study of livebirth data from the National Vital Statistics System (NVSS) was conducted, comprising of 9.6 million singleton livebirths among first-time mothers aged 15-49 years from 2016 to 2022.

PARTICIPANTS/MATERIALS, SETTING, METHODS

Information on infertility treatment use and CCHD was obtained from the health and medical information section of birth certificates, which was completed by healthcare staff after reviewing medical records. Logistic regression models were used to estimate odds ratios (OR) and 95% CI. Entropy balancing weighting analysis and probabilistic bias analysis were also performed.

MAIN RESULTS AND THE ROLE OF CHANCE

The proportion of births following infertility treatment increased from 1.9% (27 116) to 3.1% (43 510) during the study period. Overall, there were 5287 cases of CCHD resulting in a prevalence of 0.6 per 1000 livebirths. The prevalence was 1.2 per 1000 live births among infertility treatment users (ART: 1.1 per 1000 livebirths; non-ART: 1.3 per 1000 livebirths) while that for naturally conceived births was 0.5 per 1000 livebirths. Compared to naturally conceived births, the use of any infertility treatment (OR: 2.06, 95% CI: 1.82-2.33), either ART (OR: 2.02, 95% CI: 1.73-2.36) or other infertility treatments (OR: 2.12, 95% CI: 1.74-2.33), was associated with higher odds of CCHD after adjusting for maternal and paternal age, race and ethnicity, and education, as well as maternal nativity, marital status, source of payment, smoking status, and pre-pregnancy measures of BMI, hypertension and diabetes. This association did not differ by the type of infertility treatment (ART versus other infertility treatments) (OR: 1.04, 95% CI: 0.82-1.33, P = 0.712), and was robust to the presence of exposure and outcome misclassification bias and residual confounding.

LIMITATIONS, REASONS FOR CAUTION

The findings are only limited to livebirths. We did not have the capacity to examine termination data, but differential termination by mode of conception has not been supported by previous studies designed to consider it. Infertility treatment use was self-reported, leading to the potential for selection bias and misclassification for infertility treatment and CCHD. However, the association persisted when systematic bias as well as exposure and outcome misclassification bias were accounted for in the analyses. Information on the underlying etiology of infertility relating to either maternal, paternal, or both factors, data on specific types of ART and other infertility treatments, as well as information on subtypes of CCHD, were all not available.

WIDER IMPLICATIONS OF THE FINDINGS

In light of the increasing trend in the use of infertility treatment in the USA, and elsewhere, the finding of the current study holds significant importance for the clinical and public health of reproductive-aged individuals. The data show that the use of infertility treatment may expose offspring to elevated odds of severe congenital heart defects such as CCHD studied here. These findings cannot be interpreted causally. While our findings can assist in preconception counseling and prenatal care for pregnancies conceived by either ART or other infertility treatments, they also support some current recommendations that pregnancies resulting from infertility treatments undergo fetal echocardiography screening.

A qualitative exploration of the eight dimensions of wellness in opioid use disorder recovery during the postpartum period

Background

Recovery from opioid use disorder (OUD) during the perinatal period has unique challenges. We examined services for perinatal women with OUD using the Substance Abuse and Mental Health Services Administration (SAMHSA) eight dimensions of wellness (DoW), which reflect whole person recovery.

Methods

We enrolled professionals from the Southwestern United States who work with people with OUD during the perinatal period. Semi-structured in-depth interviews were conducted from April to December 2020. Participants were shown the DoW diagram (emotional, social, environmental, physical, financial, spiritual, occupational, intellectual) and asked to share how their clinic/agency addresses each DoW for perinatal people with OUD. Responses were transcribed and coded by two researchers using Dedoose software.

Results

Thematic analysis revealed ways professionals (n = 11) see how the services they provide fit into the DoW. This included: the need to provide mothers emotional support with a nonjudgmental approach, groups providing social support; guidance on nutrition, self-care, and a focus on the mother/infant dyad; assistance with employment and activities of daily living; parenting education; connecting mothers with resources and grants; providing a variety of spiritual approaches depending on the desire of the mother; and navigating the interpersonal environment as well as the physical space.

Conclusions

There are opportunities to expand the treatment and services provided to women with OUD during the perinatal period within all eight DoWs. Additional research is needed to identify effective strategies to incorporate these components into patient-centered, holistic care approaches.

Elective transfer of one embryo is associated with a higher cumulative live birth rate and improved perinatal outcomes compared to the transfer of two embryos with in vitro fertilization

Objective

To compare the effects of initial elective single embryo transfer (ieSET) and initial double embryo transfer (iDET) strategies on the cumulative live birth rate (CLBR) and perinatal outcomes after IVF.

Design

Retrospective cohort study.

Setting

Society for Assisted Reproductive Technology (SART) reporting clinics.

Patient(s)

49,333 patients with initial oocyte retrievals between January 2014 and December 2015.

Intervention(s)

None.

Main Outcome Measure(s)

The primary outcome was CLBR, defined as up to 1 live birth resulting from a retrieval cycle and linked transfer cycles. Secondary outcomes included cycles to pregnancy, multifetal delivery rate, infant birthweight, and perinatal mortality rate.

Result(s)

Compared to iDET, ieSET was associated with increased CLBR (74% vs. 57%; adjusted odds ratio [AOR], 1.32; 95% CI, 1.26–1.38). When stratified by age, the same trend was seen in all age categories, with statistical significance for those <38 years of age. ieSET was associated with reduced multifetal delivery (8% vs. 34%; AOR, 0.13; 95% CI, 0.12–0.14), increased birthweight (mean difference, 406 grams; 95% CI, 387–425), reduced preterm births (1.2% vs. 2.8%), and reduced perinatal mortality (0.5% vs. 1.2%). Compared with iDET, ieSET was associated with slightly more embryo transfer cycles (1.7 vs. 1.4 cycles; AOR, 1.19; 95% CI, 1.16–1.21) to achieve a pregnancy resulting in live birth.

Conclusion(s)

The association of ieSET with a higher CLBR and markedly improved perinatal outcomes outweigh the relatively minor increase in time to pregnancy, reinforcing the guidance for eSET in initial transfer cycles, particularly in younger patients with a good prognosis.
