| Abstract |
In the past several decades, rates of delayed childbearing have increased, and as a result, maternal age has advanced. Our objective was to evaluate whether advanced maternal age is independently associated with an increased risk of childhood cancers in the offspring. A retrospective cohort study of women who delivered between the years 1991 and 2014 was conducted. Elderly parturients (≥ 35 years) were divided into two sub-categories: 35-39 and 40-50 years. The comparison group consisted of parturients aged 20-34 years. All hospitalizations of offspring up to the age of 18 years involving malignant morbidity were compared between the groups. A Kaplan-Meier survival curve was used to compare cumulative malignant morbidity incidence of the offspring. A Weibull regression model was used to control for confounders. During the study period, 201,738 deliveries met the inclusion criteria. Of them, 16.3% (n = 32,804) occurred in mothers aged 35 years or more (35-39 years old n = 26,145, 79.7%; 40-50 years old n = 6659, 20.3%). In the Weibull regression model, advanced maternal age exhibited no association with general malignant morbidity in the offspring up to 18 years of age (mothers aged 35-39: adjusted HR 1.06, 95% CI 0.76-1.48, p = 0.727; mothers aged 40-50: adjusted HR 0.73, 95% CI 0.36-1.46, p = 0.373). For leukemia, the regression model exhibited an independent association in maternal ages of 35-39 (adjusted HR 2.23, 95% CI 1.34-3.69, p = 0.002). Advanced maternal age does not appear to raise the risk for future malignancy in the offspring up to the age 18 years. The specific nature of the association between maternal age and leukemia of the offspring necessitates further investigation. What is Known: • Advanced maternal age is associated with a marked elevation in the risk of different pregnancy complications and adverse pregnancy outcomes. What is New: • Advanced maternal age does not appear to raise the risk for future malignancy in the offspring up to the age 18 years. • Leukemia of the offspring may be associated with advanced maternal age although the specific nature of the association necessitates further investigation. |

Attention Score in Context
This research output has an Altmetric Attention Score of 14. This is our high-level measure of the quality and quantity of online attention that it has received. This Attention Score, as well as the ranking and number of research outputs shown below, was calculated when the research output was last mentioned on 26 June 2018.
All research outputs
#2,196,333
of 23,041,514 outputs
Outputs from European Journal of Pediatrics
#293
of 3,760 outputs
Outputs of similar age
#49,451
of 329,011 outputs
Outputs of similar age from European Journal of Pediatrics
#13
of 55 outputs
Altmetric has tracked 23,041,514 research outputs across all sources so far. Compared to these this one has done particularly well and is in the 90th percentile: it's in the top 10% of all research outputs ever tracked by Altmetric.
So far Altmetric has tracked 3,760 research outputs from this source. They typically receive more attention than average, with a mean Attention Score of 8.7. This one has done particularly well, scoring higher than 92% of its peers.
Older research outputs will score higher simply because they've had more time to accumulate mentions. To account for age we can compare this Altmetric Attention Score to the 329,011 tracked outputs that were published within six weeks on either side of this one in any source. This one has done well, scoring higher than 84% of its contemporaries.
We're also able to compare this research output to 55 others from the same source and published within six weeks on either side of this one. This one has gotten more attention than average, scoring higher than 74% of its contemporaries.
