Science journalism Why would the Mayo Clinic update their article about family planning to remove the reported risks of having children too close together?
I am asking here because I’m wondering if there is a better source for this information, as a parent.
The Mayo Clinic article about family planning used to have a section where it discussed the risks of beginning a new pregnancy within 6 months of giving birth. It was reported that doing so put the second child at a greater risks of developing certain conditions, including schizophrenia and autism. The article went on to acknowledge that parents over 35 may feel additional pressures for family planning and recommended that they wait 12 months after a pregnancy to get pregnant again.
This is the article I’m referencing:

I’ve referenced that article several times. Recently that section of the article was removed. Here’s an old comment of mine where I had quoted the article.

It might be that newer studies no longer support this. You could try to inquire with them on why the article has been updated. It sure would be interesting.

I've seen a couple of the popular OBs on social media discuss that it's not as important as we previously thought but I haven't seen data to back that up.

My OB’s guideline is 6 months after vaginal delivery and 12 months after c section

My OB said 18mo minimum to start trying after c-section. My fertility doctor agreed. She wouldn’t even see me until after that.
But every place seems to say something different.

u/eyerishdancegirl7 Feb 15 '25
Yeah. It’s different everywhere. The waiting until 18 months has a lot to do with your body needing that time to replenish nutrients, and is recommended whether or not you have had a vaginal or cesarean birth.
My provider said I could start trying at 9 months PP (18 months between deliveries) and I had a planned c-section.
All this to say, everyone’s risk tolerance is different. I know women who’ve had 3 c-sections in 4 years who’ve had no issues. And women who’ve had back to back vaginal deliveries a year apart, also no issues.
So I could see that being part of the reason why Mayo Clinic would update this.

Ours highly encouraged to have at least 18 month spacing between children in general and 2 years if you want to attempt a VBAC.

12 months to conception, or birth?

u/firewaffles0808 Feb 15 '25
You can start trying again 6 months after vaginal birth and 12 months after c section (preferably)

This is what my OB said too when I asked. I was 36 and had my first child vaginally (but had fertility struggles).
When I expressed to my OB that I wanted to have another child and it may take 1-2 years to get pregnant she advised me to wait 6mo before trying.
Honestly, I didn’t feel ready until 12 months pp to start trying for another.

The cited references for the articles are different. The new one cites to an August 2024 paper. I’d look to see if the new information is from that 2024 paper.

beware, chat gpt isn't pulling each reference article to compare them, its just giving you what it thinks the answer could be.

To elaborate a little on this for other people new to AI, ChatGPT (free version) doesn’t have unfettered access to the internet so it can’t pull and parse links. It does use web crawlers to train, but that is different.

I use the paid subscription for ChatGPT. All of the responses I posted in this thread are from ChatGPT 4.0

u/PainfulPoo411 Feb 15 '25
While you are correct that ChatGPT has to be promoted appropriately to get correct answers, in this case it is correct:
- Schummers et al. (2018) – Article 1
This study examined the association between short interpregnancy intervals (IPIs) and pregnancy outcomes, considering maternal age. The researchers found that short IPIs are linked to increased risks of adverse pregnancy outcomes across all age groups. Notably, the study highlighted that women aged 35 and older face higher risks of maternal mortality or severe morbidity with short IPIs.
Quote:
“The findings of this study suggest that short interpregnancy intervals are associated with increased risks for adverse pregnancy outcomes for women of all ages.” 
- Liberman et al. (2022) – Article 2
This research focused on the prevalence of specific birth defects in relation to both short and long IPIs. The study found that both short and long intervals are associated with an increased prevalence of several birth defects, such as gastroschisis and tetralogy of Fallot.
Quote:
“In this population-based study, we observed increased prevalence of several birth defects with short and long IPI.”

Maybe the research previously linking close gap to schizophrenia & autism is outdated and disproven. That would be 1 reason why they’d rewrite that whole section

They are probably having their articles over a certain age updated by technical writers or marketers specializing in SEO. It was probably another one who wrote it originally. Their team tells the contracted marketers what they are looking for and then they have a subject matter expert check it for anything incorrect. These articles are never expert written only expert reviewed. They can be very good but it's not like you are actually following a single individual or even enteties writing with their own consistency and knowledge base.

Seems like they made it its own article on jan 25: https://www.mayoclinic.org/healthy-lifestyle/getting-pregnant/in-depth/family-planning/art-20044072

That seems to be the same article I linked.

I really don't like how article 2 is more conversational in tone. It doesn't feel professional to me.

Dang I didn't know that. I accidentally got pregnant when my son was around 4 months old. Now I have a daughter. I hope I didn't ruin her life

u/TheSorcerersCat Feb 15 '25
Lots of people do, it's often fine. It's just that maybe some risk factors increase to both mom and baby.
But an increase in risk factors is all relative. If a risk is 0.1% you can double it at be at 0.2% likelihood and many people would find that acceptable. (Making up numbers here). But say a risk is typically 5% and doubling it gets you to 10% likelihood. Then maybe you wanna consider if that's worth it to you.
Ideally though, you do want pregnancy to be further apart mostly to protect yourself. Things like your calcium reserve should ideally be replenished before having another baby.

I couldn't find any recent study that addresses this concern at all. Most studies within the last 2 years that focused on Interpregnancy Intervals, have only focused on immediate or short term maternal health or immediate baby related health risks such as low brith weight or preterm birth etc. I also couldn't find any new studies published within the last 2 years that focused on IPI connected to autism or schizophernia. The most recent Meta Analysis was done in 2023, looked at 8 different studies and found that "both substantially short (< 24 months) and excessively long Interpregnancy Intervals/IPIs (> 72 months) are significantly correlated with an increased risk of Autism Spectrum Disorder"

Did they cave to political pressure? So many health websites are being censored now. This does sound like information that Catholics and pro-life folks wouldn’t care for. I hope I’m wrong.
