Risk Factors-Maternal age at conception
Posted on  21st June 2015

Recent decades have witnessed an increase in mean maternal age at childbirth in most high-resourced countries. Advanced maternal age has been associated with several adverse maternal and perinatal outcomes. Although there are many studies on this topic, data from large contemporary population-based cohorts that controls for demographic variables known to influence perinatal outcomes is limited.

Method

We performed a population-based cohort study using data on all singleton births in 2004–2008 from the North Western Perinatal Survey based at The University of Manchester, UK. We compared pregnancy outcomes in women aged 30–34, 35–39 and ≥40 years with women aged 20–29 years using log-linear binomial regression. Models were adjusted for parity, ethnicity, social deprivation score and body mass index.

Results

The final study cohort consisted of 215,344 births; 122,307 mothers (54.19%) were aged 20–29 years, 62,371(27.63%) were aged 30–34 years, 33,966(15.05%) were aged 35–39 years and 7,066(3.13%) were aged ≥40 years. Women aged 40+ at delivery were at increased risk of stillbirth (RR = 1.83, [95% CI 1.37–2.43]), pre-term (RR = 1.25, [95% CI: 1.14–1.36]) and very pre-term birth (RR = 1.29, [95% CI:1.08–1.55]), Macrosomia (RR = 1.31, [95% CI: 1.12–1.54]), extremely large for gestational age (RR = 1.40, [95% CI: 1.25–1.58]) and Caesarean delivery (RR = 1.83, [95% CI: 1.77–1.90]).

Conclusion

Advanced maternal age is associated with a range of adverse pregnancy outcomes. These risks are independent of parity and remain after adjusting for the ameliorating effects of higher socioeconomic status. The data from this large contemporary cohort will be of interest to healthcare providers and women and will facilitate evidence based counselling of older expectant mothers.

My advise
1...     From the beginning I am advising not to postpone for your Pregnancy
2..      Your age plays an important role in your pregnancy.
3..      Women's fertility gradually declines with age, especially in the mid-30s, and it drops rapidly after age 37. Infertility in older women is likely due to the lower number and quality of eggs, and can also be due to health problems that affect fertility. Men over age 40 may be less fertile than younger men. Tobacco use

4...   The ability of a woman's ovaries to release eggs ready for fertilization declines with age. The health of a woman's eggs declines with age. As a woman ages she is more likely to have health problems that can interfere with fertility. As a women ages, her risk of having a miscarriage increases

5...   More and more women are waiting until their 30s and 40s to have children. Actually, about 20 percent of women in the United States now have their first child after age 35. So age is an increasingly common cause of fertility problems. About one third of couples in which the woman is over 35 have fertility problems.

6...   Most healthy women under the age of 30 shouldn’t worry about infertility unless they’ve been trying to get pregnant for at least a year. At this point, women should talk to their doctors about a fertility evaluation. Men should also talk to their doctors if this much time has passed.

7...  From the beginning I am telling U to conceive in your young age not later than 30 years.

8..    I advise every woman not postpone for pregnancy.

9..      Eat Healthy food and drink sufficient water
10..    Be positive and happy with your life partner.
