Key Points

‧ There appears to be a relationship between poor sexual health and cognitive function.

‧ Improvements in sexual satisfaction can improve memory.

‧ Circulatory problems can lead to declined sexual and cognitive function.

A bad sex life might predict memory problems in your later years. A recent study has found that middle-aged men who reported decreasing sexual satisfaction and erectile function as they got older also tended to experience greater cognitive decline at the same time. The findings suggest that our sexual health is closely tied to our brain health, though more research is needed to better understand this link, the study authors say.

Past studies have found a connection between sexual and cognitive function, including in older adults. But much of this research has relied on studying people at singular points in their life. In this new study, led by scientists at Penn State University, the team had access to data that allowed them to follow people over time.

Specifically, they analyzed data from hundreds of older men enrolled in the Vietnam Era Twin Study of Aging (VETSA), an ongoing study that’s trying to pin down the genetic and environmental factors that affect people’s aging brains. More than 800 men were included in the team’s analysis, with an average age of 56 at the start of the study. These men answered questions about their lives and had their cognition and memory tested across three waves of the study over a 12-year period.

Men’s self-reported sexual satisfaction at the start of the study wasn’t linked to their initial cognitive function, the researchers found. But men whose sex lives began to decline over the years often experienced memory decline as well. Men who reported erectile dysfunction also tended to have worse cognitive function at the beginning and throughout the study.

“When we mapped the relationship over time, we found increases or decreases in erectile function and sexual satisfaction were associated with concurrent increases or decreases in cognitive function,” said co-lead author Riki Slayday, a doctoral candidate at Penn State, in a statement released by the university. “These associations survived adjustment for demographic and health factors, which tells us there is a clear connection between our sex lives and our cognition.”

The team’s results were published in the latest issue of the journal Gerontologist.

Longitudinal studies are better than similar types of research at showing a genuine association between any two factors—in this case, sexual and brain health. This study alone still can’t tell us the direction of this relationship, though, meaning whether one causes the other or if both are influenced by another unaccounted factor. But the authors do have some theories. Men with worsening sex lives can experience greater stress as a result, which could then affect their cognitive health, for instance. Subtle damaging changes in our body’s circulation are also known to raise the risk of erectile dysfunction in men and could plausibly harm our brains as well.

The authors say their findings at the very least indicate that older men’s declining sexual health can be an early warning sign of memory problems. Ideally, this might also mean that people can help keep their brains sharp by proactively addressing issues with their sex life.

“Improvements in sexual satisfaction may actually spark improvement in memory function. We tell people they should get more exercise and eat better foods. We’re showing that sexual satisfaction also has importance for our health and general quality of life,” study author Martin Sliwinski, professor of human development and family studies at Penn State, said in a statement.

Our Takeaways:

· Better sleep will reduce the chance of becoming more frail in advanced age.

· Men and women appear to have different risk factors concerning bone and muscle loss.

· Those with more consistent sleep profiles also reported functioning better during the day in areas of alertness and cognitive function.

A study found that having a better sleep health composite score was associated with a lower risk of physical frailty, with men and women possessing different risk factors.

A study published in Sleep Health found that there was an association between healthy sleep in multiple dimensions and the risk of becoming physically frail. The risk was different in men and women.

The study took place in Taiwan and data were obtained from the Taiwan Longitudinal Study on Aging (TLSA), which includes patients 60 years and older. Patients who were younger than 65 years and/or were living in a long-term care facility were excluded from this study. Patients with missing information or other covariates were also excluded.

Modified definitions of frailty under the Fried criteria were used for this study. Sleep measures were self-reported using the 5 sleep health dimensions in the SATED model: sleep satisfaction, daytime alertness, sleep timing, sleep efficiency, and sleep duration. Physical activity was assessed by frequency of engaging in gardening, walks, bicycling, jogging, hiking, and other outdoor physical exercise.

There were 2015 participants for this study, of whom 9% were considered frail. The mean sleep health composite score was 2.51; the most prevalent good sleep health dimension was daytime alertness (91%) and least prevalent was sleep efficiency (11%).

Participants who were frail scored significantly lower on the sleep health composite compared with participants who were not frail, and significantly fewer frail participants indicated satisfaction with sleep, being alert during the daytime, and having adequate sleep duration.

The adjusted logistic regression analysis demonstrated a significant association between frailty and the multidimensional sleep health composite (odds ratio [OR], 0.57; 95% CI, 0.49-0.68). The effect remained significant after adding comorbidity, cognitive function, pain, depressive symptoms, drinking, smoking, and exercise to the model (OR, 0.78; 95% CI, 0.64-0.94). Individuals who scored 1 point higher on the sleep health measure were approximately 22% less likely to be frail.

The multidimensional sleep health composite effect on frailty was significant in both female (OR, 0.59; 95% CI, 0.48-0.72) and male (OR, 0.54; 95% CI, 0.39-0.75) participants. A significant effect was only observed in women (OR, 0.79; 95% CI, 0.63-0.98) after adjusting for comorbidities.

The adjusted logistic regression analysis found that sleep satisfaction (OR, 0.34; 95% Ci, 0.24-0.48), daytime alertness (OR, 0.21; 95% CI, 0.14-0.31), and sleep duration (OR, 0.50; 95% CI, 0.34-0.74) were associated with frailty. When considering individuals’ health, only daytime alertness remained as a significant association (OR, 0.46; 95% CI, 0.29-0.75).

Sleep satisfaction (OR, 0.29; 95% CI, 0.19-0.44), daytime alertness (OR, 0.29; 95% CI, 0.18-0.47), and sleep duration (OR, 0.48; 95% CI, 0.30-0.78) were associated with frailty in women but were no longer significant when adding health and risk behaviors to the model. Sleep satisfaction (OR, 0.47; 95% CI, 0.24-0.94) and daytime alertness (OR, 0.10; 95% CI, 0.05-0.21) were associated with frailty in men, although only daytime alertness remained significant after adding health and risk behaviors to the model.

There were some limitations to the study. The cross-sectional design of this study could cause reverse causality. The investigators used self-reported responses to construct an adopted frailty index due to constraints of archival data. Napping, which is often associated with frailty, was not found in the TLSA data set, and therefore couldn’t be tested. Sleep disorders can also increase the risks of frailty but were not available in the TLSA data set.

The researchers concluded that the first empirical evidence of sleep health being an early risk factor of frailty was demonstrated in the study.
