Perimenopause may offer a key window to spot heart disease risk earlier, with women in the transition twice as likely to have low heart health scores, new research suggests.

The findings suggest the transition to menopause could be an important time to reassess risk and prompt lifestyle changes.

Garima Arora is senior author of the study and professor of medicine in the division of cardiovascular disease at the University of Alabama at Birmingham.

Arora said: “Mid-life women should think of the perimenopausal period as a ‘window of opportunity.’

They should be proactive and not wait until they reach menopause to start checking their blood pressure, cholesterol and blood sugar levels.

“Women should talk with their health care team about their reproductive status and any changes they are experiencing. It may be the perfect time to get a baseline for their heart health.”

The analysis included 9,248 women aged 18 to 80 who took part in the National Health and Nutrition Examination Survey between 2007 and 2020.

Researchers used Life’s Essential 8, a heart health score developed by the American Heart Association. It measures diet, physical activity, tobacco use, sleep, blood pressure, cholesterol, body weight and blood sugar on a 100-point scale.

Median scores fell as women moved through reproductive stages, from 73.3 out of 100 in premenopausal women to 69.1 in perimenopausal women and 63.9 in postmenopausal women.

Among the individual Life’s Essential 8 measures, diet consistently had the lowest scores and continued to decline across all reproductive stages.

After accounting for age, perimenopausal women were twice as likely to have a low overall score as premenopausal women.

They were also 76 per cent more likely to have a low cholesterol score and 83 per cent more likely to have a low blood sugar score.

The researchers said fluctuations in oestrogen levels during perimenopause may contribute to lower cardiovascular health because they may affect cholesterol, insulin resistance, blood pressure and weight management.

Insulin resistance means the body does not respond properly to insulin, the hormone that helps control blood sugar.

Sleep duration scores remained high across all reproductive stages, despite perimenopausal women reporting difficulty sleeping, suggesting sleep quality may be more affected than sleep length.

Amrita Nayak, lead author of the study and research fellow in the division of cardiovascular disease at the University of Alabama at Birmingham, said the findings highlight a point where risk may begin to rise.

She said: “Our analysis highlights that perimenopause, women’s reproductive transition period to menopause, is the critical time when the increase in cardiovascular risk seems magnified.

“When we compared women’s LE8 scores to the premenopausal baseline, the perimenopausal group was the first to show a significant jump in the odds of having low heart health.”

Arora added that nutrition could be an important area for early intervention.

“Nutrition can be a central factor for early and proactive intervention.

“Focusing on heart-healthy habits early, especially getting regular exercise and following a healthy eating plan like the DASH diet with a focus on lowering salt can help improve cardiovascular health for perimenopausal women in the years to come.”

Stacey E. Rosen, volunteer president of the American Heart Association, who was not involved in the study, said the findings underline the need to consider women-specific risk factors across life stages.

“This research highlights yet another aspect of the unique factors that increase a woman’s risk of cardiovascular disease throughout the stages of her lifespan.

“Significant health changes during pregnancy, perimenopause and menopause make it particularly important to pay close attention to increases in health risk factors during those times.

“I encourage women to talk with their primary care and specialty health care teams to learn about early detection and modification of traditional and ‘female-specific’ risk factors.

“Women can take proven steps to improve their cardiovascular health at all ages.”

The researchers said the next step is to follow women over several years to track hormone levels and heart health, which may help clarify the long-term impact of perimenopause and how lifestyle changes could reduce risk.

Women over 40 are seeking raves for mental and physical wellbeing, with a study suggesting the benefits go beyond nightlife.

The findings challenge the idea that nightlife and electronic dance music events are mainly for younger people.

Published in Psychology of Music, the study focused on the common misconception that nightlife is only for younger audiences.

Researchers surveyed 136 female clubbers aged 40 to 65 about their experiences at electronic dance music events.

The study, carried out at the University of Leeds in England, found women reported mental and physical wellbeing benefits from attending these events.

Seeing favourite DJs was the most common motivation, but many women also described dancing as a way to relieve stress and find emotional support.

The research found that 65.9 per cent of participants described attending a rave as “spiritual”, while 62.9 per cent said it offered an escape from everyday life.

A further 58.3 per cent said they felt like a different version of themselves in a club environment.

Nine in ten participants said they felt at home at electronic dance music events, with many pointing to a shared passion for music and the sense of community around it.

The study also suggested physical fitness played a role, with some women saying they had made clubbing part of their regular exercise routine.

However, the findings also highlighted challenges for older women in nightlife spaces.

One fifth of participants said they felt visibly out of place because of their age.

Nearly half reported unwanted physical contact, leading some to seek out different venues or attend only with friends.
