Maternal age of menarche and blood pressure in adolescence: evidence from Hong Kong's "Children of 1997" birth cohort.
The mean maternal age of our sample was 24.9 ± 5.9 years).
The mean maternal age of the macrosomia group was 24.74±3.32 years, which is slightly older than that in the control group (24.35±3.14 years, P = 0.000).
Fleming's team, also part of EpiHealth, is focusing on the effects of maternal age, of embryo vitrification – a form of freezing – and of different periods of embryo culture: three common themes within IVF-related medical treatment.
Results: Thirty-one women underwent the EXIT procedure, with an average maternal age of 29 years (range, 20 to 38), and average gestational age of 34 weeks (range, 29 to 40).
The purpose of this study was to examine the risk of infertility that is associated with paternal age, because this factor rarely has been investigated, whereas maternal age of ≥35 years is a well-known risk factor.
In conclusion, the association between TREM2 and both parental history of AD and younger maternal age of AD onset provide additional support for the role of TREM2 in AD and illustrate the importance of considering family history in AD study design.
Carriers were more likely to have a parental history of AD (100% of carriers vs. 70% of noncarriers; p = 0.01) and, among the parental history subset, families with a TREM2 carrier had a younger maternal age of AD onset than noncarriers (67.9 vs. 75.6 years; p = 0.03).
Maternal characteristics demonstrate a mean maternal age of 21.8 (±3.9) years, 40% (n=15) were primiparous, and fewer than 10% (n=4) of mothers reported a history of alcohol use, and all denied cigarette smoking and NSAID use.
This finding is supported by the finding in the literature where maternal age of less than 18 years is found to be associated with inadequate use of prenatal care in Aracaju, Northeast Brazil [50].
The study samples included 233 adults from HLNRA and 77 adults from NLNRA with mean maternal age of 26.24±4.52 years and 25.69±4.38 years, respectively.
