Women with multiple risk factors are more likely to experience adverse outcomes such as maternal ICU admission, preterm birth, low birthweight, and fetal death.
A new study led by Dr Gizachew Tessema found that a 15-year-old WHO recommendation to wait at least 24 months after a previous birth may be too long for mothers in high-income countries. The research discovered no increased risk of adverse pregnancy outcomes after an interpregnancy interval of less than six months.
A newly discovered class of immune cells may prevent the mother's immune system from attacking the placenta and fetus. Researchers found that pregnant mice without these cells were twice as likely to miscarry, with severely restricted fetal growth in many cases.

A new study shows that personalized online coaching can help women improve their lifestyle behaviors before and after pregnancy, particularly in overweight women. The coaching program resulted in significant reductions in smoking and drinking alcohol, as well as increased odds of becoming pregnant.
Research suggests that exposure to air pollution during pregnancy may increase a baby's risk of obesity and related diseases. Hispanic mothers who lived in areas with high levels of pollutants had babies who grew unusually fast, gaining excess fat that puts them at risk of obesity later in life.
Two studies find that a plant-based diet protects rats from hypertension and preeclampsia, even when exposed to high-salt diets. The researchers believe that dietary alterations can shift the gut microbiota, reducing disease incidence.
A new study explores how Haitian women's beliefs and values influence their decision making about pregnancy and birth after a C-section. Key findings highlight the importance of family, friends, and providers, as well as cultural background and fear of pain, in shaping birth plans.
Researchers found that a mother's birth weight and litter size were associated with early neonatal death, but not adult maternal characteristics. The study suggests that current approaches to understanding perinatal mortality are incomplete and highlight the need for further research on structural and intergenerational factors.

The study also found differences in touch and movement behaviors between singletons and twins.
A population-based study published in JAMA found no association between maternal influenza vaccination during pregnancy and adverse early childhood health outcomes. The study followed over 28,000 children from birth to 3 ½ years old, indicating that flu vaccination during pregnancy does not increase the risk of immune-related or non-im...
Researchers discovered that hormone biomarkers from the placenta can identify women at risk for pregnancy complications, which affect around one in ten pregnant women. The study found that these biomarkers are present from the first trimester and can lead to earlier diagnosis and treatment.
A study published in Human Reproduction found that women who drink alcohol are less likely to conceive, with heavy drinking associated with a 61% reduced odds of becoming pregnant. Moderate drinking during the luteal phase also linked to lower conception rates, highlighting the importance of avoiding alcohol for those trying to conceive.
Prenatal supplements may affect breast milk microbiota composition, while maternal obesity can impact child health. Physical activity during pregnancy is linked with epigenetic changes that influence offspring health.

High levels of glucose altered protein expression and secretion, while insulin changes triggered quantitative changes in protein secretion without significant gene transcription.
The COVID-19 pandemic initially slowed down conception rates, but a baby surge is expected as pregnancy volumes rebound. Researchers at Michigan Medicine used electronic health records to model pregnancy episodes and project changes in pregnancy volumes during the pandemic.
A secret shopper study found that pregnant women are 20% less likely to be accepted for opioid treatment than non-pregnant women, citing long on-hold times and difficult interactions. The study highlights the need for increased access to medication-assisted treatment (MAT) regardless of pregnancy status.
Postpartum women in bad romantic relationships are more likely to suffer symptoms of depression and have lower heart rate variability (HRV), which can impact long-term wellness and mortality. Research shows a clear link between relationship quality during pregnancy and postpartum depression and HRV.
The COVID-19 pandemic led to changes in pregnancy and birth rates, with increased cesarean deliveries and emergency C-sections reported during lockdowns. Researchers analyzed electronic medical records to estimate the impact of lockdown measures on reproductive health.
