Can Waist-To-Hip Ratio Predict Heart Disease? What Women 50+ Should Know
You've likely heard about the importance of keeping your weight in a healthy range to protect your heart. But the number on the scale may not be telling the full story. Your waist-to-hip ratio (WHR) could be an even more revealing measure when it comes to cardiovascular risk, especially for women over 50. But what exactly is WHR, how do you calculate it and what numbers should you be aiming for? We spoke with healthcare experts to break it all down, including what your WHR says about your heart health and what to do if your number is high.
Waist-to-hip ratio is a measurement comparing the circumference of your waist to that of your hips. 'It's a simple way of looking at how fat is distributed on your body,' explains Hussain Ahmad, MUDr/MD, consultant practitioner for Click2Pharmacy. More specifically, it determines whether a person carries more fat around the abdomen or the lower body. While body mass index (BMI) estimates overall body fat, WHR provides insight into where that fat is stored.
So, how does this relate to your heart? 'People with more fat around the waist tend to be at higher risk of cardiovascular disease compared to those who carry more weight around their hips and thighs,' says Dr. Ahmad. 'That's because belly fat, especially the kind that builds up around internal organs (visceral fat) is more strongly linked to heart issues.'
Increased visceral fat surrounds vital organs, producing inflammatory compounds that negatively impact heart function. This, Dr. Ahmad continues, can lead to an increased risk of developing high blood pressure, high cholesterol and insulin resistance.
According to the American Heart Association, carrying more abdominal fat, even with a healthy BMI, can increase your risk of cardiovascular issues. Moreover, a 2023 study in JAMA Network Open found that WHR may be a better predictor of future health issues, including cardiovascular health, than BMI. This is especially important for postmenopausal women, who tend to shift fat storage to the abdomen due to hormonal changes. WHR offers a more targeted look at your metabolic health risk.
The good news is you don't need any fancy tools to calculate your WHR. 'You can take a measuring tape horizontally around the abdomen,' says Richard Frank, MD, MHSA, chief medical officer at Vida Health. 'The tape must be snug, but not so tight that it compresses the skin, and parallel to the floor.' Here's how to do it:
Measure your waist at its narrowest point, usually just above your belly button.
Measure your hips at their widest point, typically around the fullest part of your buttocks.
Divide your waist measurement by your hip measurement. For example: 32' waist ÷ 40' hips = 0.80 WHR.
'A WHR greater than 0.85 for women and 0.90 for men increases metabolic risk,' says Dr. Frank. 'Women naturally have higher fat storage around the hips, so the threshold for a high WHR is lower for women.'
While WHR is helpful, it's not the only number that matters. 'It does provide a better insight into fat distribution than using BMI alone, however, it should not be used in isolation,' says Pamela Walters, MD, medical director at Eulas Clinics. 'Other critical risk factors include blood pressure, blood sugar levels, whether you smoke, how active you are, cholesterol levels and so on.'
Dr. Walters also notes that stress and mental health conditions, such as depression, are also associated with heart disease. 'Addressing both physical and mental health together leads to better outcomes across the board,' she says. (You can see more risk factors for heart disease in women here.)
Additionally, WHR has its limitations. First, it doesn't account for overall body composition or muscle mass. This means two people with the same ratio and similar body shapes could have very different health profiles. It also can't distinguish between visceral fat and subcutaneous fat (the kind just under the skin). 'WHR is a useful tool, but like BMI, it's just one part of the picture,' says Dr. Ahmad.
If your WHR is higher than ideal, don't panic. There are small, sustainable lifestyle changes that can help reduce abdominal fat and improve your heart health overall.
What you eat and when can play a big role. 'Increasing fiber intake and balanced macronutrients, staying hydrated and decreasing late-night eating can improve WHR and help decrease visceral fat,' advises Dr. Frank. Other tips he shares include adding strength training to your workout routine, managing stress and getting proper sleep.
'Overall, consistency with dietary and lifestyle changes is crucial,' says Dr. Frank. He cites several medical conditions that can affect your WHR, including thyroid conditions, PCOS, menopause and Cushing's disease. 'However, management is the same with or without these conditions as well as treating underlying conditions,' he adds.
While WHR may not be a perfect predictor, it does offer important insight into how your body stores fat and how that might impact your cardiovascular system.

AHA: Effects of Modest Alcohol Use on the Heart Unclear
Several medical groups have concluded regular consumption of alcohol in any amount poses a health risk, but a new scientific statement from the American Heart Association (AHA) offered more qualified guidance. The premise that moderate alcohol use reduces cardiovascular risk has been widely accepted for decades. The authors of a 1993 editorial in The New England Journal of Medicine concluded 'there now seems little doubt' that such a benefit exists. However, a review of the evidence in 2025 produced a more cautious summary. 'Considering the level of evidence, it remains unknown whether drinking is part of a healthy lifestyle, and therefore, clinicians should reinforce healthy lifestyle behaviors such as regularly engaging in physical activity, avoiding tobacco use, and maintaining healthy body weight,' the AHA document stated. Complex Mix 'Data from recent studies using new methodologies (eg, individual participant-level data meta-analysis and mendelian randomization [MR]) have challenged the idea that any level of alcohol consumption has positive health effects,' according to authors of the new statement, led by Mariann R. Piano, RN, PhD, senior associate dean for research at the Vanderbilt University School of Nursing, in Nashville, Tennessee. Prior to the new methodologies, protection against coronary artery disease from moderate alcohol use was derived from many observational studies. These studies used a variety of definitions of moderate drinking but typically considered that threshold to be two or fewer drinks per day for men and one or fewer drinks per day for women. In pooled analyses cited in the AHA statement, reductions in risks of 10%-15% relative to no drinking were common. Yet analyses of alcohol consumption are complex, even leaving aside how a standard drink is defined or whether the risk calculations are needed for every type of alcohol, according to Piano and her colleagues. In addition, any potential benefit is eliminated by moderate drinkers who binge intermittently, according to several examples in the AHA statement. The new methodologies for addressing the question of the safety of moderate drinking do not fully reverse conclusions that it is beneficial. They suggest little or no protection rather than harm. In one pooled analysis of MR studies, the finding was a 'weak association' for benefit, which differs markedly from assertions that moderate drinking might be justified for a benefit to cardiovascular health. Following a detailed review of the evidence for both moderate and heavy alcohol use on cardiovascular risks and risk factors, the AHA statement summarized messages clinicians can deliver to patients, but strict conclusions were limited to the harm of heavy drinking. The messages on moderate drinking largely consisted of talking points. For coronary artery disease specifically, the AHA statement acknowledged that moderate drinking 'may provide some risk reduction' for the condition even if this reduction has been rendered less clear by studies using analyses designed to apply more rigor for evaluating observational data. For heart failure, the statement concluded that low-to-moderate alcohol consumption has not been associated with any beneficial or detrimental effect, although this statement is qualified with a citation suggesting five or more drinks per week may contribute to left ventricular dysfunction. Moderate Alcohol and Hypertension For patients who already have hypertension, the statement cautioned even moderate consumption of alcohol can contribute to elevated blood pressure — one of the few statements to link moderate alcohol use to a specific adverse effect on a cardiovascular risk factor. The authors characterized alcohol abstention as a reasonable part of lowering blood pressure in hypertensive patients. For stroke, moderate alcohol use has produced mixed results, according to the AHA statement. One possible explanation for the increased risk for stroke in some studies might relate to the association of moderate alcohol with elevations in blood pressure among those who already have hypertension. For arrhythmias and cardiomyopathies, low alcohol intake or abstention might be better than moderate or heavier drinking, even if data supporting this contention are limited, according to the AHA statement. For example, although a prospective study associated abstinence with a reduction in the burden of atrial fibrillation, the analysis, like the vast majority of studies cited in the AHA statement, was not a randomized comparison. The focus of the new document was on cardiovascular health, but several health organizations taking a broader view of health risks have recently cautioned against alcohol use in general. Among them are the World Health Organization, which issued a statement in 2023 that 'no level of alcohol consumption is safe for our health,' and the CDC, which earlier this year called for warning labels on alcoholic beverages linking consumption to cancer. A 2023 report from the Canada called the Guidance on Alcohol and Health also called for drinking less as a general step to better health. In the US, where a 2023 governmental survey found more than 50% of adults reported drinking alcohol within the past month, the US Department of Agriculture did not make definitive claims about the relationship between low-level alcohol use and health risks in its recent Dietary Guidelines for Americans. Despite the recommendations the AHA listed for clinicians when advising patients, an urgent call was made for prospective studies that can confirm benefit, or at least the absence of risk, regarding moderate drinking. The list of gaps in knowledge in the statement was long. The orientation regarding moderate alcohol use in relation to cardiovascular disease has shifted, according to Jamal S. Rana, MD, PhD, a clinical cardiologist and adjunct investigator in the Division of Research at Permanente Medical Group, Oakland, California. At this point, 'I think we should move away from the overarching public messaging that one should drink because it is good for heart health,' said Rana, who has been involved in several studies regarding alcohol use and cardiovascular risk. For moderate use, he suggested the caution about potential risks should not exceed the evidence. Even if newer evidence is challenging the long-held belief that moderate alcohol offers some degree of cardioprotection, significant harm has been most closely associated with heavy alcohol use. As for advising patients, he said he agrees in general with the AHA statement summary of the evidence: Risks should be emphasized to patients who drink more than moderately, but 'drinking socially with low amounts of alcohol is okay.'

At-Home tDCS Improves Fibromyalgia Pain
A noninvasive, home-based brain treatment with transcranial direct current stimulation (tDCS) can reduce pain severity, improve pain-related disability, and enhance endogenous pain modulation in women with fibromyalgia, suggested the results of a clinical trial published in JAMA Network Open . The study included 112 women between the ages of 18 years and 65 years with fibromyalgia. Half received anodal tDCS (A-tDCS), which applied 2 mA of electrical current through electrodes placed on the scalp over the left dorsolateral prefrontal cortex, for 20 minutes daily and 5 days per week. The other half used a lookalike sham device that did not deliver sustained stimulation. In addition, all participants completed exercise and pain neuroscience education. At the end of the 4-week treatment period, and after a 3-month follow-up, study participants rated their pain from 0 (none) to 10 (worst pain) for seven activities. Patients who used tDCS experienced an average 39% reduction in pain, and 62.5% of them had a 50% or more improvement in pain. In comparison, subjects who used the sham device experienced an average 16% reduction in pain. tDCS also reduced pain severity compared to sham treatment. 'These results are consistent with evidence suggesting that stimulating the left dorsolateral prefrontal cortex enhances top-down control over pain, emotion, and cognitive processing,' said study author Wolnei Caumo, MD, PhD, professor of anesthesia and pain in the medical school at Federal University of Rio Grande do Sul, Porto Alegre, Brazil. 'The moderate to large effect sizes observed reaffirm expectations about the clinical relevance of targeting the prefrontal cortex in fibromyalgia.' How Does tDCS Reduce Fibromyalgia Pain? Prior research suggested that tDCS applies low-level electric currents to modulate neuronal excitability and neuroplasticity. Modulating activity in the brain's dorsolateral prefrontal cortex in particular can enhance control over pain processing networks and reduce pain catastrophizing, Caumo said. 'This region is implicated in both cognitive control and emotional regulation,' said E. Baron Short , MD, MSCR, a professor of psychiatry and medicine at the Medical University of South Carolina, Charleston, South Carolina. To understand how the placebo effect might influence the results, the patients had been randomly assigned to either treatment group and then stratified according to placebo test response; patients were evenly split between the A-tDCS and sham tDCS groups and between responders and nonresponders such that of the 56 placebo test nonresponders assigned to A-tDCS, 28 received sham treatment and 28 received active treatment, and of the 56 placebo test responders assigned to sham tDCS, 28 received sham treatment and 28 received active treatment. They found that placebo responses influenced pain intensity but not pain interference or psychosocial measures. 'While a placebo can shape subjective pain perception, functional improvements require active neuromodulation,' Caumo said. 'Moreover, placebo responders in the sham group regressed toward baseline at follow-up, while A-tDCS responders sustained their gains, highlighting the limited durability of placebo-only effects.' In this study, tDCS didn't act alone — the education and exercise that participants completed are also beneficial in fibromyalgia. 'The evidence so far says that for chronic pain, the two therapeutic approaches that have the best evidence are pain science education and physical exercise,' said María Teresa Carrillo De La Peña, PhD, a professor of clinical psychology and psychobiology at the University of Santiago de Compostela, Santiago de Compostela, Spain, who studies novel treatments for chronic pain and cancer pain. Exercise promotes the production of pain-relieving endorphins. And when patients learn about the brain's role in pain perception and processing, they start paying more attention to the psychological and social factors that affect their pain, she said. 'Sometimes patients think that their pain is in the knee or the back, and they are waiting for a solution for that,' she said. 'Thanks to pain science education, we stress that we need to attend to the brain.' How Could Patients Fit Home-Based tDCS Into Their Fibromyalgia Treatment Mix? 'Given the limited and often poorly tolerated options currently available for fibromyalgia, I do believe tDCS deserves serious consideration, particularly for patients who have not responded to conventional treatments or who struggle with medication side effects,' Baron said. 'Its relative safety, ease of use, and the growing body of supportive evidence position it as a viable adjunctive treatment.' The current study demonstrates that home-based tDCS is feasible, safe, and something patients stick with. The device used in the study was designed to be user-friendly with guidance from a healthcare professional who controls the electrode placement and timing settings. 'It reduces transportation, cost, and time barriers, [which are] especially relevant for patients with chronic pain and mobility limitations,' Caumo said. 'Additionally, the unsupervised model mimics real-world conditions and enhances scalability and autonomy, making it a cost-effective and patient-centered alternative to clinic-based sessions.' Autonomy is powerful for patients with pain. 'One of the most important things that we are seeing right now in the management of pain is that the patient takes this active role,' Carrillo De La Peña said. This trial was supported by grants from the Brazilian National Council for Scientific and Technological Development, the Postgraduate Research Group at the

Eating this fatty snack every day can help you sleep better — scientists were surprised
Those delicious darlings on every brunch menu may be more than just a creamy topping. It turns out this popular green fruit — yes, it's a fruit — may just be the key to restful slumber, according to a new study in the Journal of the American Heart Association. Researchers tracked 969 adults aged 25 and over who had abdominal obesity, which is characterized as a waistline that is 35 inches or more for women and 40 inches or more for men. For 26 weeks, half of the group ate one large Hass avocado per day while the other half continued their usual diet, which typically involved consuming less than two avocados per month. As expected, the avocado-eating group saw marked improvements in their blood lipids — fatty substances like triglycerides and cholesterol — and overall diet. But what caught researchers off guard was the fact that this trendy toast-topper also led to better sleep. The researchers noted that avocado's impact on sleep may be due to its powerhouse blend of nutrients, as it's 'rich in monounsaturated fatty acids, dietary fiber, potassium, folate, vitamin K, copper and pantothenic acid.' It also came as a surprise that avocado consumption was not associated with improved cardiovascular health, which was actually the original purpose of the study. The researchers noted that avocados could benefit slumber as part of a balanced, healthy diet and should not be treated as a solitary sleep aid. 'Sleep is emerging as a key lifestyle factor in heart health, and this study invites us to consider how nutrition — and foods like avocado — can play a role in improving it,' said Dr. Kristina Petersen, study author and associate professor of nutritional sciences at Penn State University. 'Cardiovascular health is influenced by many factors, and while no single food is a silver bullet, some — like avocados — offer a range of nutrients that support multiple aspects of heart health. This is an encouraging step in expanding the science around avocados and the potential benefits of consumption.' Other factors that can improve your sleep include cutting down on caffeine, curbing alcohol intake, kicking a smoking habit, exercising and limiting screen time before bed. This isn't the first time the versatile superfood has made headlines for unexpected benefits. Previous research suggests avocados may reduce 'bad' cholesterol and help with belly fat in women, thanks to their healthy fats and high fiber content. A 2024 study suggests that eating a small amount of avocado every day may lower a woman's risk for Type 2 diabetes. Just make sure not to overdo it. Experts generally recommend eating no more than one avocado per day to avoid unwanted weight gain.
