Unusual trend in the prevalence of trisomy 13 in mothers aged 35 and older: A population based study of national congenital anomaly data

ConclusionThe unexpected declining trend in trisomy 13 in older mothers could not be explained by the risk factors examined in this study. There have been no other reports of trends in the prevalence of trisomy 13 in older mothers in recent years. There is further need for surveillance of trends in future and in other populations.
