Sex and the Senile

Geriatric sexuality is a very sparsely explored domain in the medical arena. With the developing world getting top heavy on the age pyramid, this has become a rather timely question to ask. This study conducted in Australia takes a look at the prevalence of sexual activities in people ages 75 years and above (upto 95 years).

The obvious problem was to recruit the study population in this age group. Given the fact that there would be several impediments of working on a long term with people of this age bracket, a high rate of attrition was to be expected. So, to make up for that, at the very starting point, an inordinately large sample was needed to be recruited. Also, the study needed to look at community dwelling population because the people in the nursing homes and other geriatric care facilities, usually a good source of study population for this age group, would have been too obviously ill to be having sex (or have several contraindications to having sex). This is how it all went down:

So eventually, thanks to massive attrition rates due to disease or death, the final study population stood at 3274.

Out of these 3274 participants, 2783 (85%) provided information regarding sexuality. In my opinion, that in itself was quite an astounding number. The data collection was done in 3 waves of questionnaires:

Questionnaires from 1996 to 1999, 2001 to 2004, and 2008 to 2009 assessed social and medical factors. Sex hormones were measured from 2001 to 2004. Sexual activity was assessed by questionnaire from 2008 to 2009.

Sexual activity was defined as a sexual encounter in the last 12 months. In the study, it was seen:

Sex was considered at least somewhat important by 48.8% (95% CI, 47.0% to 50.6%), and 30.8% (CI, 29.1% to 32.5%) had had at least 1 sexual encounter in the past 12 months. Of the latter, 56.5% were satisfied with the frequency of activity, whereas 43.0% had sex less often than preferred.

An interesting point to be noted in the graph above is that whilst the numbers of people who considered sex to be not at all important rose dramatically with increasing age and those considering sex to be moderately important dropped dramatically with increasing age, there was quite consistency in the number of people considering sex to be extremely important and very important across all age groups. Whether the numbers are just a chance finding thanks to the large population surveyed or whether there is something more to this is a matter to be debated, but it definitely shows that with increasing age, the socially accepted norm of sexual abstinence is dropping. The traditionally accepted notion that sex in the elderly is not only inappropriate, but also immoral, (1) stands challenged here.

The common barriers to sex in the 1926 men who said that they were not sexually active are an interesting medico-socio-religious blend:

Lack of interest was reported by 40.5% (n = 780), physical problems or limitations by 48.4% (n = 932), lack of a partner by 20.9% (n = 402), grieving by 4.1% (n = 78), and concern that children or family members would not approve by 2.3% (n = 44). Lack of interest by the partner or physical problems or limitations of the partner were cited by 39.5% (n = 761) and 22.9% (n = 441), respectively. Other reasons were given by 5.6% (n = 108); the most common were age (n = 68), medication use (n = 13), and celibacy for religious reasons (n = 7).

It is an interesting study in that it also measured the testosterone levels of the study populations at survey waves 2 and 3. In longitudinal analyses, it was seen, quite expectedly, that higher testosterone levels were associated with increased likelihood of having a sexually active life, while coexisting comorbidities were associated with lower odds of having sex. the question whether endogenous testosterone is an important player in regulating sexuality in elderly males (2) has been asked time and again, and this study, again, albeit indirectly, places some amount of importance on this aspect. Smaller studies with more stress on hypothesis generation than testing them have been done to assess whether testosterone supplementation has any beneficial effect on elderly male sexuality, but they have been poorly powered in general. some studies have shown that libido and erectile dysfunction in elderly males have improved with the supplementation of testosterone in hypogonadal males, it seemed to be of little benefit to the men with normal testosterone levels (3).

Although the study is rigorously designed and conducted with adequate sample size, there are several limitations which are well-nigh impossible to overcome in studies concerning this population:

  1. The high rates if attrition over the long period of the study meant that the study sample was healthier than the average population. Which means there was a survivorship bias.
  2. Sexuality is a topic which is intensely personal and hence there always is a risk of bias in any observational study dealing with it, whatever be the age group.
  3. This is a study which brings a very specific population into question. Depending upon the socio-cultural norms, the results are expected to vary wildly. Until and unless the study gets replicated in more diverse socio-cultural-economic backgrounds, it shall remain a niche result, not generalizable globally.
  4. This is not per se a weakness of this study, but it takes into account the community living population only. While the ones in nursing homes or geriatric care centers may be too sick to be having sex, analyzing their attitudes to sex is indeed an interesting angle on the topic.
  5. One more aspect that could have been visited is the care givers’ attitudes towards the sexuality needs of the geriatric population and whether the geriatric population use the resources for sexual health.
  6. Serial blood samples to record Testosterone levels would have been more specific indicator of the role of endogenous testosterone as a player in determining the sexual activities of the geriatrics.
  7. As in any questionnaire based study, recall bias remains a worry, even if the questionnaire is made as simple as possible: which, again, may not in itself be a good thing.
  8. This was not an anonymous study (although there was single blinding and the analysts were not aware of the respondents’ identities). This would mean that the elderly population, who anyways have a more conventional and orthodox view on sex (4), would be more likely to not mention “socially censured behavior” resulting in a response bias.
  9. The “satisfaction with sex” is a vague and individualized concept. As an abstract notion, it is difficult to translate into quantitative terms.

An interesting study, indeed, especially considering the fact that the very country in which this study was conducted, Australia, the Institute of Health and Welfare, forgot to mention about the sexual health of the geriatric population in their publications (5). Since medications play some role in inhibiting the sexual needs of the geriatric population, as healthcare providers, we need to be acutely aware of the needs. Depending upon the cultural contexts, elderly people may not be able to voice their concerns regarding the medications which may hamper their sexual needs with their healthcare providers. This study shows that there is a significantly larger population of elderly people who consider to sex to be an important part of their lives, but are not being able to meet their sexual needs. As healthcare providers, we need to cultivate an enabling environment where they are able to express their needs and whether any medications (beta blockers, anti depressants, etc.) are standing in the way.

Traditionally, sex has been the symbol of youth and vigor. But with an aging population and a significantly increased number of elderly people staying more interested with it, sex is fast becoming their playground too!

  3. I think in North America, the age group with the highest rise in rates of gonorrhea is the 50-65 age group.

  5. I never thought about it. Old men and women still want to have sex? Whoa! Well, for whatever purposes it is, I hope they get to that point where they feel that they are already satisfied.

  6. I think the “not at all” triangles kind of say it all. By 90, even just the trouble of getting the clothes off and on and getting you two ….together…… Well, it’d have to be pretty mindblowing to be worth it, and then someone’s liable to have a heart attack. The risk is high to break a hip…..I bet even 20 year olds wouldn’t do it very often if they snapped a bone easily. 6 months of PT for one roll in the hay? Cost/Benefit analysis says Nope. Those who are practical about what’s important to them in life seem to live a long, long time. I’d love to see the same diagram, but with “Importance of Sodoku”. Bet it’s a mirror image!
