Call for NHS-backed period tracking app to protect women’s data from commercial misuse

Published

on

Public health bodies should create official period tracking apps to compete with commercial versions, experts say, amid rising concerns over how private companies collect and sell women’s sensitive health data.

Cycle tracking apps (CTAs), often presented as tools for empowerment or managing fertility, are a “goldmine” for advertisers, according to research from the University of Cambridge.

Many collect details ranging from diet and medication to sexual activity and contraception use—often without users realising how the data is used.

The report, by Cambridge’s Minderoo Centre for Technology and Democracy, warns that the business model behind most CTAs is built on profiting from personal health data. It says the lack of regulation leaves users exposed to risks.

Dr Stefanie Felsberger, the report’s lead author, said: “There are real and frightening privacy and safety risks to women as a result of the commodification of the data collected by cycle tracking app companies.”

She warned that data could be used to affect job prospects, allow workplace surveillance, increase the risk of health insurance discrimination, or limit access to abortion.

Although the apps are marketed as health tools—particularly for those trying to conceive—the report says they operate in a system where user data is routinely shared with third parties for profit.

Information about pregnancy is particularly valuable for targeted advertising—estimated to be worth more than 200 times as much as data on age, gender or location.

The report notes that data could also be used to target women depending on the stage of their cycle.

The three most-used period tracking apps were downloaded globally around 250 million times in 2024.

The wider femtech market—which includes digital tools aimed at women’s health—is expected to exceed US$60bn by 2027.

The authors call for stronger oversight of the growing femtech sector and clearer consent options for users.

They argue that public health agencies should offer transparent alternatives to commercial apps, with clearer data use policies.

Felsberger said: “The UK is ideally positioned to solve the question of access to menstrual data for researchers, as well as privacy and data commodification concerns, by developing an NHS app to track menstrual cycles.”

She noted that the US reproductive health provider Planned Parenthood already has its own app, while the UK currently lacks a comparable public option.

Felsberger said: “Apps situated within public healthcare systems, and not driven primarily by profit, will mitigate privacy violations, provide much-needed data on reproductive health, and give people more agency over how their menstrual data is used.”

Professor Gina Neff, executive director of the Minderoo Centre, added: “The use of cycle tracking apps is at an all-time high.

“Women deserve better than to have their menstrual tracking data treated as consumer data.”

Elimination of cervical cancer in EU an ‘achievable goal’, report finds

Published

on

Cervical cancer elimination in the EU is becoming achievable as HPV vaccination coverage rises, a new report says.

As Europe marks European Immunisation Week 2026, the European Centre for Disease Prevention and Control said progress in human papillomavirus vaccination is continuing across the EU and European Economic Area.

All EU and European Economic Area countries now recommend HPV vaccination for adolescent girls and boys as part of their immunisation programmes, marking a major step forward in Europe’s cancer prevention efforts.

Bruno Ciancio, head of unit, directly transmitted diseases and vaccine preventable diseases at the European Centre for Disease Prevention and Control, said: “The elimination of cervical cancer in the EU/EEA is becoming an achievable goal, thanks to the HPV vaccination programmes.

“The progress we are seeing across Europe demonstrates what can be accomplished when countries invest consistently in effective immunisation strategies.

“We are closely monitoring this progress and actively supporting countries to accelerate uptake and move faster towards cervical cancer elimination.”

According to the report, three EU and European Economic Area countries, Iceland, Portugal and Norway, have reached the 2024 EU Council Recommendation target of 90 per cent HPV vaccination coverage among girls by the age of 15.

Fifteen years after HPV vaccination programmes were introduced in Europe, a growing body of evidence confirms the vaccine is highly effective in preventing cervical cancer.

Large-scale studies from Sweden, the Netherlands and Denmark, as well as other parts of the world, have shown significant reductions in HPV infections and precancerous lesions, which are abnormal cell changes that can develop into cancer if left untreated, alongside falling cervical cancer rates among vaccinated women.

Since 2020, European countries have reported a decreased incidence of cervical cancer among vaccinated women.

Studies from Sweden, Denmark and the UK show that early administration of the vaccine increases its full protective potential.

A Swedish study suggested that vaccinating girls before their 17th birthday reduced the incidence of cervical cancer by 88 per cent.

An additional six-year follow-up found a sustained reduction in cervical cancer risk and a population-level decline in invasive cervical cancer incidence after HPV vaccination.

The report showed that vaccination programmes and health system design are critical factors in reaching high levels of HPV vaccination coverage.

Evidence from across Europe showed that school-based vaccination programmes are particularly effective and tend to reach higher levels of coverage among both girls and boys.

Poor mental health, poverty and pollution significantly raise women’s heart failure risk – study

Published

on

Poor mental health, poverty and pollution can raise women’s heart failure risk, with up to one in four cases potentially preventable, a study has found.

UK Biobank data from more than 230,000 women suggest that depression, socioeconomic hardship and exposure to polluted environments are linked to a significantly higher risk of heart failure in women.

Heart failure happens when the heart becomes too weak or too stiff to pump blood effectively around the body.

High blood pressure, high cholesterol, smoking and diabetes are among the better-known risk factors often targeted in public health campaigns.

Peige Song from China’s Zhejiang University and her team found that living in polluted areas, having poor mental wellbeing, facing socioeconomic deprivation and experiencing chronic inflammatory conditions such as lupus, in which the immune system attacks the body’s own tissues, make women more prone to heart failure.

These risks, however, are often overlooked.

The researchers found that mental wellbeing, environmental exposures, socioeconomic circumstances and reproductive history together contributed almost as much risk for heart failure as all well-known risk factors combined.

The study also found that risk rises with socioeconomic hardship and chronic inflammatory conditions such as lupus or rheumatoid arthritis, approaching the impact of conventional risk factors.

Song said: “[The study] is a call to redefine prevention in women’s cardiovascular health, integrating biological, psychosocial and structural determinants into a unified, equitable approach.

“One in four heart-failure cases in women could be prevented if all under-recognised risk factors were eliminated, assuming causal relationships.”

While completely eliminating all risks is not realistic, Song said “even partial reductions through better mental health services, social equity policies and environmental regulations could yield significant public health benefits”.

Catherine Pirkle, a women’s health specialist at the University of Hawaiʻi at Mānoa in the US, who was not involved in the study, said: “These calculations show convincingly that under-recognised and female-specific risk factors contribute significantly to heart failure in women, independently of the well-established ones.”

Song said: “It’s important to understand that heart health is influenced by more than just blood pressure or cholesterol.

“Factors like mental wellbeing, reproductive milestones and socioeconomic conditions all matter. Awareness and advocacy for comprehensive, gender-sensitive care are key.”

Resistance training has preventative effects in menopause, study finds

Published

on

Resistance training improves hip strength, balance and flexibility during menopause and may also improve lean body mass, research suggests.

A study of 72 active women aged 46 to 57 found those who completed a 12-week supervised programme saw greater gains than those who kept to their usual exercise routines.

None of the participants were taking hormone replacement therapy.

The supervised, low-impact resistance exercise programme focused on strength at the hip and shoulder, dynamic balance and flexibility.

Participants used Pvolve equipment, including resistance bands and weights around the hips, wrists and ankles, and also lifted dumbbells of varying loads.

Women in the resistance training group showed a 19 per cent increase in hip function and lower-body strength, a 21 per cent increase in full-body flexibility and a 10 per cent increase in dynamic balance, meaning the ability to stay stable while moving.

Those in the usual activity group did not show any significant improvements.

Previous studies have assessed the decline in lower limb strength and flexibility during menopause, but this is said to be the first study to compare the effect of resistance training on muscle strength and mass before, during and after menopause.

This was done by including participants in different phases of menopause rather than following the same participants over a long timeframe.

Francis Stephens, a researcher at the University of Exeter Medical School in the UK, said: “These results are important because women appear to be more susceptible to loss of leg strength as they age, particularly after menopause, which can lead to increased risk of falls and hip fractures.

“This is the first study to demonstrate that a low-impact bodyweight and resistance band exercise training programme with a focus on the lower limbs, can increase hip strength, balance, and flexibility.

“Importantly, these improvements were the same in peri- and post-menopausal females when compared to pre-menopausal females, suggesting that changes associated with menopause do not mitigate the benefits of exercise.”

Although one of the researchers sits on Pvolve’s clinical advisory board, the researchers said the company did not sponsor the study or influence its results.

Stephens added that any progressive resistance exercise training focused on lower-body strength is likely to yield the same results.

He said: “The important point is for an individual to find a type of exercise, modality, location, time of day etc., that is enjoyable, sustainable, and improves everyday life.

“The participants in the present study reported an improvement in ‘enjoyment of exercise,’ and some are still using the programme since the study finished.”

Kylie Larson, a women’s health and fitness coach and founder of Elemental Coaching, who was not involved in the study, said the results were compelling.

She said: “This is particularly exciting for those that tend to think of menopause as ‘the end’. The study proves that if you incorporate strength training you can still make improvements to your muscle mass and strength, which will also have a positive ripple effect to your ability to manage your body composition.

“In addition, staying flexible and being able to balance are both keys to a healthy and functional second half of life.”

Participants in the study did four classes a week for 30 minutes each session, but Larson said even half that amount of strength training can go a long way, particularly if you emphasise progressive overload, which means gradually increasing muscle challenge through more weight.

Larson said: “Gradually increasing the challenge is what drives real change.

“Lifting heavier over time is what builds strength, protects your bones, and keeps your body resilient through menopause and beyond.”
