Pandemic stressors taking a toll on pregnant patients’ mental health
Pregnant patients surveyed by Kaiser Permanente researchers early in the COVID-19 pandemic reported more severe mental health symptoms when they were distressed about changes in prenatal care, childcare challenges, and food insecurity. A second study found disparities in how Black and Hispanic pregnant individuals experienced pandemic stressors compared with white patients.
No difference found in infant outcomes between glyburide and insulin for gestational diabetes
A study of 11,321 patients treated for gestational diabetes with insulin or the medication glyburide did not find a difference in cesarean section rates or outcomes for the patients’ infants, suggesting many people with gestational diabetes could forego insulin injections in favor of taking a pill.
Coronavirus may double severe complications in pregnancy
A Kaiser Permanente analysis of pregnant patients who tested positive for the coronavirus found more than double the risk of poor outcomes including preterm birth, venous thromboembolism (blood clot), and severe maternal morbidity, which includes conditions such as acute respiratory distress syndrome and sepsis.
Blood pressure patterns in early pregnancy tied to later risk of pregnancy-related hypertension complications
Kaiser Permanente research suggests blood pressure patterns seen during the first 20 weeks of pregnancy may offer critical clues to identify the patients most likely to develop high blood pressure complications later in their pregnancies.
Study finds no link between autism and common antidepressant when used in pregnancy
Mothers with psychiatric conditions such as depression and anxiety were more likely to have a child with autism than mothers without such conditions, new research led by Kaiser Permanente investigators finds. But the analysis found no association between use of common antidepressants by pregnant women and likelihood of autism in their children.
5 Questions for… Lyndsay Avalos
To help pregnant women make informed decisions, Division of Research (DOR) investigator Lyndsay Avalos, PhD, MPH is leading a study to shed light on the nuances of depression treatment during pregnancy. Avalos recently received a $3 million grant from the National Institutes of Health to study the topic.
Study identifies geographic clusters of pregnant women who missed flu shots
A Kaiser Permanente analysis of women who did not get flu shots during their pregnancies found the women clustered in geographic “hot spots.” These women tended to have fewer prenatal medical visits and live in low-income neighborhoods.
Telephone coaching helped pregnant women with overweight or obesity manage gestational weight gain
Pregnant women with overweight or obesity better controlled their weight gain and improved health behaviors when they received a series of telephone sessions with a registered dietician, a new study from Kaiser Permanente finds.
Blood test to identify risk for diabetes after pregnancy in women with gestational diabetes now one step closer
New findings from Kaiser Permanente Division of Research SWIFT Study in PLOS Medicine advance a potential blood test to predict which women with gestational diabetes will go on to develop type 2 diabetes.
Depressed pregnant women more likely to eat poorer diets, Kaiser Permanente analysis finds
Pregnant women with depression were more likely to eat poor diets with a higher intake of empty calories and lower intake of greens, beans, and fruit, according to an analysis of 1,160 adult pregnant women who were treated at Kaiser Permanente Northern California.
Study in pregnant women suggests maternal infection, not antibiotics, associated with childhood obesity
Women who had an untreated infection during pregnancy were more likely to have a child who later went on to be obese than pregnant women who never had an infection, new research from Kaiser Permanente finds.
Use of CT scans during pregnancy increased in U.S. and Canada over 2 decades
A large, multicenter study of advanced medical imaging in pregnancy, published in JAMA Network Open and co-led by Marilyn Kwan, PhD, found that CT scans were performed in 0.8% of pregnancies in the United States and 0.4% in Ontario in 2016; these rates increased nearly fourfold in the United States and doubled in Ontario over the 21 years.
More women using cannabis daily before and during pregnancy, Kaiser Permanente research finds
The number of women using cannabis in the year before they get pregnant and early in their pregnancies is increasing, and their frequency of use is also rising, according to new data from Kaiser Permanente.
Mother’s pregnancy weight linked to early puberty in daughters
A Kaiser Permanente study of more than 2,000 mothers and daughters found that the amount of weight mothers gained during pregnancy — whether too much or too little — was linked to the earlier onset of puberty in their daughters; the associations were even stronger when the mothers were overweight or obese at the beginning of the pregnancy.

Women who start their period later, go through menopause earlier or have a hysterectomy may have a greater risk of developing dementia, according to a new study led by Kaiser Permanente researchers and published in the journal, Neurology.
New Guidelines for Perinatal Depression are Important, but Barriers Remain
New recommendations suggest that clinicians should provide or refer pregnant and postpartum women who are at increased risk of perinatal depression to counseling interventions. These recommendations are “an important step forward” wrote research scientists and doctors at Kaiser Permanente, in a JAMA Pediatrics editorial.
Work by the Division of Research Makes Top JAMA Lists for 2018
