Sex Hormones During Pregnancy and Child Development

 


Sex Hormones During Pregnancy and Child Development

This project aims to examine associations between maternal blood levels of sex hormones during pregnancy and child development, including in children with and without autism.

Summary

Sex hormones during pregnancy can have a significant impact on brain development, behavior, and health, yet knowledge in this area remains limited. Autism can present differently in children assigned to females at birth compared to those assigned to males, and the lack of research on autistic traits in girls may contribute to delayed recognition and diagnosis.

 A better understanding of hormonal influences could improve knowledge of how autism traits manifest in boys and girls, potentially facilitating earlier identification and more tailored support and accommodations.


A substantial part of the disabling challenges experienced by autistic individuals stems from co-occurring mental health conditions such as anxiety and depression. Understanding how hormonal factors contribute to developing these co-occurring conditions could be important for early identification and intervention.


This project aims to examine associations between maternal blood levels of sex hormones during pregnancy and child development, including in children with and without autism. The study will utilize data and biological samples from the Norwegian Mother, Father, and Child Cohort Study (MoBa). Additionally, it will incorporate autism-related data from the Autism Birth Cohort Study (ABC Study), the autism sub-study within MoBa.


No analyses have been initiated yet, as the project's first step is to gather insights and feedback from user representatives to refine research questions and analytical approaches. The user panel includes neurodivergent researchers and lived-experience consultants from the Norwegian Autism Association. The project also builds on insights from focus groups and interviews with autistic consultants conducted at the Autism Research Centre at the University of Cambridge.

The Side Effects Of Pregnancy And Childbirth

  The Side Effects Of Pregnancy And Childbirth  Between the good, the bad, and the ugly, pregnancy is most certainly a wild ride. And anyone who has gone through childbirth knows there are plenty of things you can never be prepared for. What's a side effect of giving birth that people don't talk about?" Here's what women said. 1.   "The night sweats for those first few weeks. Buy new sets of sheets so the daily bedding changes are more manageable." 2.   "How brutal sleep deprivation feels. Navy Seals deal with sleep deprivation. It is a brief eternity of misery. Good thing for kids " 3.   "All stretch marks you gloriously avoided during pregnancy could come AFTER. PFFF" 4.   "Bleeding nipples, especially for baby number one, before they’ve figured out their latch," 5.    You can keep getting contractions for a couple of days after birth. And that they can get stronger with subsequent births. 6.   "The overall confusion of br...

Is waking linked to caloric Intake in pregnant women

  The length of time to the meal after waking is linked to  caloric  Intake in pregnant women There is a link between taking longer to eat an initial meal after waking up and increased caloric intake later in the day  in pregnant women, along with taking longer to sleep after the last meal, according to a recent study published in  Sleep Science. 1 Increasing research has been performed about the link between the timing of food intake and metabolic health, with  investigators noting that eating and sleep behaviors should not occur at the same time of the day. This makes the time  between awakening and the first meal as an important health factor, with increased health risks reported from skipping  this meal. 2 Effects of maternal food timing “It is inferred that the timing of maternal food intake has the potential to influence maternal and fetal circadian rhythms,  fetal development during pregnancy, and the subsequent metabolic health of the...

  11 foods to avoid during pregnancy While most foods and drinks  are  safe to have during pregnancy, there are some things you should be careful with or avoid Knowing what you can and can’t (or rather, shouldn’t) eat during pregnancy is a bit of a minefield. Which foods should you avoid during pregnancy? Are some foods unsafe in pregnancy? Or harmful? Numerous studies recommend avoiding certain foods during pregnancy due to potential risks to both the mother and the developing fetus. These risks include: Risk of food poisoning According to the  Centers for Disease Control and Prevention  (CDC): ‘pregnant women are about 10 times more likely than other people to get listeriosis.’ A  2014 study  revealed that listeriosis during pregnancy can lead to severe outcomes, including  miscarriage , stillbirth, and neonatal infections. High mercury levels Mercury, particularly in the form of methylmercury found in certain fish, is e...
