The secret to a longer life lies in your sleep

[Oct 6, 2022: Alona Emodi-Perlman, Tel Aviv University]

If you’re a woman and over 50, we recommend that you find out whether or not you snore at nights (your bed partner may already have alerted you to the issue). TAU researchers found that women aged 55 and over who snore are at increased risk for sleep apnea, which can be fatal. Because the phenomenon occurs during sleep, most women who suffer from sleep-disordered breathing are not aware that they are at increased risk.

“The lack of early diagnosis is particularly noticeable in one of the target demographic groups: women over the age of 50, who suffer from an increase in the incidence of sleep-disordered breathing due to hormonal changes that occur during menopause,” warns TAU’s Prof. Ilana Eli, adding “We wanted to examine and characterize the phenomenon in this group in order to raise a red flag when necessary.”

The following study was conducted by Dr. Alona Emodi-Perlman, Prof. Ilana Eli, Dr. Jawan Sleiman and Dr. Pessia Friedman-Rubin from the Department of Oral Rehabilitation at The Maurice and Gabriela Goldschleger School of Dental Medicine at Tel Aviv University, and was published in the prestigious Journal of Clinical Medicine.

The researchers examined hundreds of Israeli women, whom they divided into two groups: women aged 20-40 (pre-menopause) and women aged 55 and over (post-menopause).

They found that 15% of the older women are at significant risk for sleep apnea, compared to only 3.5% of the younger women. In addition, they found that 11% of the women who snore are at increased risk for sleep apnea, compared to only 1% of the women who do not snore.

In the study, the participants filled out dedicated questionnaires, which included a variety of questions such as: How do you feel when you get up in the morning: Fatigue, headache, tension/stiffness in the muscles of the face, neck and jaw? Do you grind your teeth at night? Do you wake up during the night? Do you feel tired or drowsy during the day? And the big question, which many women are ashamed of answering: Do you snore?

The data were weighted with physical indicators – BMI and neck circumference, which is known to thicken in old age, as well as demographic data – work, number of children, marital status, etc. The findings make it possible to define three categories of risk for sleep apnea: women who are at high, medium and low risk.

Prof. Eli explains that sleep breathing disorders range across a broad spectrum – from mild snoring to the most severe and dangerous disorder – sleep apnea. Sleep apnea causes a decrease in blood oxygen concentration and can, as mentioned, be life-threatening.

In addition, if the phenomenon is not diagnosed and treated in time, it can contribute to the development of a variety of systemic diseases, such as hypertension, cardiovascular disease and stroke.

The difficulty in diagnosing it is mainly due to lack of awareness and under-reporting: women suffering from the problem are unaware of it because it occurs during sleep.

Women are more likely to report fatigue, headaches, masticatory muscle soreness upon awaking or sleep problems like insomnia to their doctors. It is therefore important that the attending physician makes the connection, asks the right questions and even seeks further diagnosis in case of suspected sleep apnea.

Grinding of teeth at night, high BMI, and a relatively large neck circumference are additional warning signs, according to the researchers.

In the wake of these findings, the researchers address doctors, and especially those who focus on the orofacial area – dentists:

The bottom line is, if you have identified a high-risk patient, refer her to a sleep diagnosis specialist. This way, we can diagnose women who are 'under the radar' due to lack of awareness and under-reporting and provide them with appropriate and life-saving care.”

The study was performed on two groups of Arab women who are not necessarily representative of their (or other) age groups. The study groups were defined only by chronological age, with no information about subjects’ physiological age and/or hormonal status.

Evaluations were carried out through self-report with no clinical examinations, which could confirm myalgia and/or the presence of probable SB. Oral conditions, such as malocclusions and/or temporomandibular disorders, which may affect the evaluated variables, were not considered.

Further studies, performed on larger groups and more diverse populations, could expand our understanding of the signs and symptoms which indicate the development of OSA in both females and males.

Future clinical implications should include development of designated mode(s) of OSA evaluation for dental patients, which will become part of standard examination procedures. Once validated, accepted, and clinically used, such tool(s) would have an important beneficial effect on public health.
