Research on affects of AMA on offspring: (Quantitative studies)
- Research done by Myrskyla & Fenelon found that only children born to mothers under 25 and over 45 are associated with negative offspring health outcomes.
- “The results suggest that children born to young parents might have been better off if the parents had waited a few years”.
- “The public health concern regarding maternal age should focus on young, not old mothers”. 
Research on affects of AMA on mothers: ()
- One study found that “increased maternal age was significantly associated with several specific…adverse outcomes”.
- In Norway, a study of women 32 and older found that they had a slightly increased risk of psychological distress during pregnancy and motherhood compared with 25-31 year olds.
- A history of depression increased the risk in all women regardless of age. Age alone does not increase the risk for depression.
- Depressive triggers are: timing of childbirth, cesarean delivery, prematurity, and a baby needing neonatal care
- Because the age of first time mothers has changed, new groups of women are exposed to psychological distress.
Research on women’s experiences and views: (Qualitative studies)
- A study done in the UK found that women have many factors that combine to influence their choice to delay motherhood.
- The factors the participants experienced were:
- Being in a relationship, financial stability, physical health, and fertility.
- Without all of these factors being aligned, women perceive an element of risk to having a baby.
- In an American study in 2008, 79 couples were interviewed about how they negotiated any kind of social stigma they experienced being older parents
- “Both women and men experienced being older parents as important personal identities”.
- Fathers “almost exclusively discussed older fatherhood as a personal identity”.
- Mothers discussed all the ways age, gender and socioeconomic status intersected and became a public identity assigned by culture.
- Women often tried to normalize older motherhood as a way of managing interactions that were stigmatizing.
- They would openly discuss how older motherhood is becoming more common in society.
- Others would assert that they were not different, but “extraordinary” and saw their older motherhood as something exceptional.
- Women also expressed that they are better mothers now than they would have been if they gave birth in their 20’s.
- They describe themselves as stable, confident, experienced and more patient.
- The author noted that older mothers “by refusing to let the potential of stigma dictate their actions” enables social change and “stereotypes will be dismantled”.
Research on birth methods:
- One study found that there has been an increase of cesarean deliveries performed for women who have no medical need.
- Cesareans increase the risk for respiratory problems in infants, greater complications in subsequent pregnancies, and longer hospital stays.
- In a study that combined findings from 21 research papers, it was found that “perceptions of safety shaped women’s preferences” in birthplace choices.
- In cultures that medicalize childbirth, women believe giving birth is only safe in a hospital.
- Women reported that felt the hospital gave them physical safety, but not emotional safety.
- Women that used a midwife found that the medicalised culture made it difficult for them to “provide all the options available to women”.
- Women felt that without being informed of all of their choices, they had no autonomy and therefore could not make an informed decision.
- However, women who used a midwife reported that they felt more in control and more satisfied with their birth experience.
- Women that used a midwife reported an increased feeling of autonomy and “experienced greater personal attention”.
Research on fertility/infertility:
- The number of births per 1000 women 35-39 years of age has increased 36% between 1992 and 2002.
- The rate among women 40-44 has increased by 70%.
- The average age for women to cryopreserve their eggs is 38, as a reactive not a proactive measure.
- Women aged 30-35 are the ideal age to cryopreserve their eggs as a proactive measure to prevent future infertility.
- At the average age of 38, a woman’s declined and can produce a lower number of oocytes.
- Cryobanks and gynecologists should inform women about cryopreservation to expand their options.
- “This would expand a woman’s reproductive options and allows them to overcome the gap between optimal age to reproduce from a gynecological point of view and the optimal age to reproduce from a socioeconomic point of view”.
