Wearables could revolutionise pregnancy monitoring, study finds

Common fitness trackers may help track pregnancy complications by detecting heart rate changes that mirror hormonal shifts, new research suggests.
The study found devices such as Apple Watch, Garmin and Fitbit recorded heart rate patterns that aligned with key pregnancy hormones including oestrogen, progesterone and human chorionic gonadotropin (hCG).
These hormones play vital roles in supporting a healthy pregnancy.
Researchers analysed data from more than 5,600 people using PowerMom, a bilingual digital research platform.
From this group, 108 provided continuous data covering three months before conception through six months after giving birth.
Heart rate data showed distinct trends. Early pregnancy was marked by a small dip around weeks five to nine, followed by steady rises until about two months before delivery, peaking at up to 9.4 beats per minute above baseline.
After birth, heart rates dropped below pre-pregnancy levels before stabilising at around six months.
The researchers also tracked sleep and activity patterns throughout pregnancy.
Giorgio Quer is co-senior author and director of artificial intelligence at Scripps Research.
Quer said: “Wearable devices offer a unique opportunity to develop innovative solutions that address the high number of adverse pregnancy outcomes in the US.
“Our results show that signals collected via wearable sensors follow the expected changes in hormone levels and can detect unique patterns specific to live birth pregnancies, potentially allowing the monitoring of maternal health throughout the pregnancy and postpartum.”
To check the link between sensors and hormones, the team compared wearable heart rate data with published hormonal changes from previous studies, building models that predicted how heart rate should shift as hormone levels rose or fell.
In an exploratory analysis of a small number of cases, pregnancies ending in miscarriage or stillbirth showed different heart rate patterns compared with healthy pregnancies, though researchers said larger groups are needed to confirm this.
“Hormones play a key role in pregnancy outcomes,” explained co-senior author Tolúwalàṣẹ Àjàyí, principal investigator of PowerMom.
“Discovering the association between heart rate and hormone changes could unlock new ways to predict the beginning of pregnancy or identify signs of adverse outcomes such as gestational diabetes or preeclampsia.”
Preeclampsia is a condition involving high blood pressure during pregnancy, while gestational diabetes means raised blood sugar that develops in pregnancy.
Researchers say the approach could help provide continuous oversight for high-risk pregnancies, particularly in underserved communities.
Previous work has shown that wearable devices can identify infections such as COVID-19 and other health issues by detecting changes in body patterns.
The team plans further work to examine variations across different groups, regions and socioeconomic backgrounds.
They aim to build models that flag those who might need closer monitoring.
Future studies will test whether wearable data could directly guide clinical decisions.
Researchers also plan to gather both wearable and blood test data from the same participants to validate the link between hormones and heart rate.

Women shouldering hidden burden of navigating healthcare system – study

Women face a hidden burden navigating healthcare, with many repeatedly retelling their medical history, a national study suggests.
The findings indicate that Canadian women are taking on cognitive, emotional and administrative work alongside managing their health, including coordinating providers and advocating for care.
More than half of women surveyed, 53 per cent, reported a past or current chronic condition, while 64 per cent said there were health topics they struggled to raise with their doctor.
Sarah Hoffman, president and CEO of Pacific Blue Cross, said: “These findings challenge us to think differently about women’s healthcare and highlight the hidden work required to navigate the system.
“For many women, managing their health has also come to mean managing the healthcare system itself.
“They are acting as project managers of their own care, shouldering the invisible labour of coordinating between providers, retelling their medical history and advocating to be heard.
“The gap between men and women is meaningful and raises important questions about why younger women report lower levels of confidence and support.
“It also challenges us to consider whether we are actually making progress in women’s care, and whether the next generation is being equipped with the confidence and voice to advocate for their health.”
Overall, 71 per cent of Canadians described their doctors as supportive and 88 per cent expected their appointments to go well.
Among women living with chronic conditions, 71 per cent reported having to repeat their complete health history multiple times a year.
Younger women were particularly likely to report difficulties discussing their health. The study found 81 per cent of Gen Z women aged 18 to 30 and 73 per cent of Millennial women aged 31 to 45 had health topics they struggled to raise with their doctor.
Among Gen Z women with chronic illness, 92 per cent reported having to repeat their complete health history.
The study also found differences between young women and men. While 95 per cent of Gen Z men expected a doctor’s appointment to go well, the figure was 82 per cent among Gen Z women.
Similarly, 82 per cent of Gen Z men said they felt supported by their family doctor, compared with 66 per cent of Gen Z women.
Reasons for holding back health concerns varied between generations.
Among Gen Z women, 30 per cent cited fear of dismissal and 29 per cent fear of judgement.
Embarrassment was the most common barrier among Millennial, Gen X and Boomer women, reported by 29 per cent, 27 per cent and 35 per cent respectively.
Women who felt they needed to prove themselves to be taken seriously said they adapted how they approached appointments.
Strategies included researching medical information, repeatedly describing or justifying symptoms, bringing written notes or documentation, tracking symptom timelines, making repeat visits and emphasising how symptoms affected their daily lives.
The study also found an association between feeling supported by a doctor and expecting appointments to go well.
Canadians who described their physician as supportive were nearly four times more likely to expect appointments to go well than those who felt unsupported, at 98 per cent compared with 25 per cent.
Overall, 66 per cent of Canadians said they described their symptoms accurately. This fell to 48 per cent among those who said they felt unsupported by their doctor.
The 2026 Blue Cross Women’s Health Study surveyed 2,045 adult Canadians online in March 2026 through independent research company Research + Knowledge = Insights.
The survey had a reported margin of error of plus or minus 2 per cent, 19 times out of 20.

Study to tackle years-long delays in endometriosis diagnosis

A study is examining where delays occur in diagnosing endometriosis – a condition that can take seven to twelve years to diagnose.
Endometriosis affects an estimated 1.5 million women and people in the UK, but there is currently no consistent way of measuring where and why diagnostic delays happen.
The research aims to develop the first standardised framework for understanding the diagnostic journey and identifying points where interventions could improve care.
The international project involves researchers from the University of Sheffield, University of Liverpool, University of Oxford, Aarhus University in Denmark and the University of Edinburgh, alongside Endometriosis UK.
Dr Rebecca Mawson, NIHR clinical lecturer in primary care at the University of Sheffield, is part of the research team.
She said: “Our project asks: where exactly are people getting lost or let down on their journey to diagnosis, and how can we map those points in a systematic way to identify where interventions could make a real difference.”
The project is led by Dr Babu Karavadra, NIHR academic clinical fellow in general practice at the University of Liverpool, who has been awarded a World Endometriosis Society Early Career Investigator Award as lead principal investigator at the University of Liverpool.
Researchers will review existing evidence, gather experiences from people living with endometriosis and bring together an international panel to map the diagnostic pathway and agree common definitions for key points along the journey.
The work will focus particularly on people whose experiences are often missing from research, including Black women, people living in rural or deprived areas, LGBTQ+ communities and disabled people.
Primary care will also be central to the research because it is often where people first seek help with symptoms.
Mawson said: “Primary care needs to be at the heart of this work. Primary care is often where people first seek help with their symptoms, so it has a crucial role in understanding diagnostic delay.
“If we only look at what happens once someone reaches specialist gynaecology, we risk missing some of the barriers that shape the journey long before that point.”
Unlike cancer research, where internationally recognised standards exist for studying diagnostic delays, endometriosis research has been more fragmented, with studies measuring different parts of the diagnostic journey in different ways.
The researchers hope to create an ‘Endometriosis Diagnostic Pathway Framework’ to help identify where people are falling through the gaps and where healthcare could be improved.
They will also develop a ‘Snakes and Ladders’ style visual representation showing how systemic barriers, chance and individual experiences can influence whether someone reaches a diagnosis.
The project forms part of the PEARL network, Primary care Endometriosis and Adenomyosis Research and Learning, an international collaboration of primary care and community researchers and clinicians.
Mawson said: “Endometriosis diagnostic delay isn’t inevitable. If we can understand where and why people are experiencing barriers, we have a much better chance of designing interventions that actually make a difference.
“The scale of the problem demands that we look at the whole journey, listen to the people experiencing it and build an evidence base that can lead to real change.”
The framework could provide the foundations for future research, clinical guideline development, healthcare professional training and NHS service improvements, with potential applications to related conditions such as adenomyosis and chronic pelvic pain.
