At any income level, if you become pregnant, you have to make a decision-is this a pregnancy you can and want to carry, or do you not want to be pregnant anymore. Choosing to continue a pregnancy carries a bunch of risks, even to people who are generally healthy.
There is a really interesting study that came out, called the Turnaway study, which followed participants with undesired pregnancies for five years. Half the participants had abortions, and the other half carried their pregnancies to term, having been denied an abortion. The people who were able to discontinue their pregnancy were better off 5 years later, in measures like physical and mental health, financially, and in their relationships.
The researchers relied mostly on participant interviews, but also pulled data like credit reports. It was really fascinating. Many participants ended up having desired pregnancies in the 5 year time frame, when it made more sense and when they were with someone who they wanted to parent with. The study used a validated scale called the Postpartum Bonding Questionnaire, which has questions like “I feel happy when my child laughs” and found that people who were denied an abortion were less likely emotionally attached to their children than people who had a wanted pregnancy after an abortion. I'm repeating this finding because It think it was one of the more unexpected parts of the study.
What I love about this study is that the efforts that the researchers went to to prove or disprove a lot of assumptions and the rhetoric surrounding Stuff like, being denied an abortion is generally more worse for mental health than receiving one. If you are interested in the topic, it’s been published as an excellent book, but there's also a really good Fresh Air episode with the study doctor, Diana Greene Foster, and she gives a lot of the highlights.
