“…During our study period, the mean maternal age increased significantly, and the proportion of mothers over 35 years of age doubled. 22 Advanced maternal age is a known risk factor for several congenital anomalies 23 , 24 and could be one factor influencing the increasing prevalence. Also, prevalence of maternal diabetes increases with advancing maternal age, 22 which further increases the risk of several congenital anomalies.…”

Background: Congenital vertebral anomalies are a heterogeneous group of diagnoses, and studies on their epidemiology are sparse. Our aim was to investigate the national prevalence and mortality of these anomalies, and to identify associated anomalies. Methods: We conducted a population-based nationwide register study and identified all cases with congenital vertebral anomalies in the Finnish Register of Congenital Malformations from 1997 to 2016 including live births, stillbirths, and elective terminations of pregnancy because of major fetal anomalies. Cases were categorized based on the recorded diagnoses, associated major anomalies were analyzed, and prevalence and infant mortality were calculated. Results: We identified 255 cases of congenital vertebral anomalies. Of these, 92 (36%) were diagnosed with formation defects, 18 (7.1%) with segmentation defects, and 145 (57%) had mixed vertebral anomalies. Live birth prevalence was 1.89 per 10,000, and total prevalence was 2.20/10,000, with a significantly increasing trend over time (P < 0.001). Overall infant mortality was 8.2% (18/219); 3.5% (3/86) in patients with formation defects, 5.6% (1/18) in segmentation defects, and 12.2% (14/115) in mixed vertebral anomalies (P = 0.06). Co-occurring anomalies and syndromes were associated with increased mortality, P = 0.006. Majority of the cases (82%) were associated with other major anomalies affecting most often the heart, limbs, and digestive system. Conclusions: In conclusion, the prevalence of congenital vertebral anomalies is increasing significantly in Finnish registers. Detailed and systematic examination is warranted in this patient population to identify underlying comorbidities as the majority of cases are associated with congenital major anomalies. Level of Evidence: Level III.

“…Recent progress in molecular biology and genetics enabled the discovery of the molecular basis of selected types of LRDs [29,30]. However, the etiology of the majority of LRDs remains unknown, and several studies highlighted the potential involvement of environmental factors [2][3][4][5]11,12,31,32].…”

“…Obesity and vitamin deficiencies (e.g., riboflavin) during pregnancy increase the fetal risk of LRDs [5,6]. Moreover, certain illnesses, injuries, and exposures to certain medications and chemical substances in the first trimester have been recognized as potential risk factors [3][4][5][6][7][8][9][10][11][12]. Nevertheless, the precise etiology of most LRDs is not well understood.…”

Maternal Risk Factors Associated with Limb Reduction Defects: Data from the Polish Registry of Congenital Malformations (PRCM)

Data from the Polish Registry of Congenital Malformations (PRCM) suggest that the prevalence of limb reduction defects (LRDs) in some Polish regions is significantly higher in comparison to that reported in the European Surveillance of Congenital Anomalies (EUROCAT) registry, but specific risk factors are still unknown. The objectives of this study were two-fold: to detect risk factors linked to isolated LRDs among Polish natives and to search for geospatial clusters of isolated LRDs to identify high-risk areas across the country. Among the 2,939,001 births accounted for in the PRCM, we determined that there were 852 children with distinct LRDs. Our data demonstrate that lower birth weight, prematurity, and maternal smoking history are strongly associated with isolated LRDs. Furthermore, our investigation pointed to various additional risk factors for isolated LRDs, including paternal education, gestational hypertension, upper respiratory tract infections, and exposure to anti-inflammatory drugs in the first trimester of pregnancy. We did not recognize statistically significant spatial or spatiotemporal clusters over the area of Poland using Kulldorff’s scan. Our study strengthens the hypothesis that maternal factors have an integral role in the etiology of isolated LRDs.

Introduction Several studies have reported on the maternal age‐associated risks of congenital anomalies. However, there is a paucity of studies with comprehensive review of anomalies. We aimed to quantify the risk of birth defects in children born to middle‐aged mothers compared with that in children born to young or older mothers. Material and methods We classified maternal ages into three groups: young (<20 years old), middle (20–34 years old) and older age (≥35 years old). Observational studies that met our age criteria were eligible for inclusion. The articles searched using the Embase and MEDLINE databases were those published from 1989 to January 21, 2021. The Newcastle–Ottawa scale was used to assess the risk of bias. If heterogeneity exceeded 50%, the random effect method was used; otherwise, the fixed‐effect method was used. Prospero registration number: CRD42021235229. Results We included 15 cohort, 14 case–control and 36 cross‐sectional studies. The pooled unadjusted odds ratio (95% CI) of any congenital anomaly was 1.64 (1.40–1.92) and 1.05 (0.95–1.15) in the older and young age groups, respectively (very low quality of evidence). The pooled unadjusted odds ratio of chromosomal anomaly was 5.64 (5.13–6.20) and 0.69 (0.54–0.88) in the older and young age groups, respectively. The pooled unadjusted odds ratio of non‐chromosomal anomaly was 1.09 (1.01–1.17) and 1.10 (1.01–1.21) in the older and young age groups, respectively (very low quality of evidence). The incidence of abdominal wall defects was increased in children of women in the young maternal age group. Conclusions We identified that very low quality evidence suggests that women in the older maternal age group had increased odds of having children with congenital anomalies compared with those in the 20–34 year age group. There was no increase in odds of children with congenital anomalies in women of <20 year age group except for abdominal defects compared with those in the 20–34 year age group. The results stem from very low quality evidence with no adjustment of confounders.
