Sexually transmitted infections (STIs) are on the rise among older adults, according to data from the Centers for Disease Control and Prevention. This trend is particularly alarming as it goes against the common misconception that STIs only affect younger populations. In this article, we delve into the reasons behind this increase in STIs among older adults, focusing on both behavioral and biological factors.
One of the key reasons for the surge in STIs in older adults is the limited understanding of STIs in this age group. Older adults may not be as well-informed about STIs as younger individuals, leading to increased risk. Additionally, infrequent condom use plays a role in the spread of STIs among older adults. Moreover, the availability of medications like Viagra and Cialis for erectile dysfunction and estrogen creams for vaginal dryness can lead to increased sexual activity in older adults, contributing to the prevalence of STIs.
Menopause, a natural process in a woman’s life, marks the cessation of menstrual periods and results in a decline in estrogen production. This decrease in estrogen levels can lead to genitourinary syndrome of menopause (GSM), characterized by vaginal dryness, irritation, and susceptibility to infections. Research has shown that menopause impacts the structural integrity of the vaginal lining, reducing the levels of proteins like desmoglein-1 and desmocollin-1 that maintain vaginal health.
Studies have compared the levels of DSG1 and DSC1 proteins in vaginal tissue from postmenopausal and premenopausal women, revealing lower levels in postmenopausal women. Animal studies involving the removal of ovaries in mice have also shown decreased levels of these proteins and increased susceptibility to infections like herpes simplex virus type 2 (HSV-2) and chlamydia. However, applying estrogen cream to mice without ovaries restored vaginal lining integrity and protected against HSV-2 infection.
Understanding the behavioral and biological factors contributing to STI susceptibility in older adults is crucial for effective prevention strategies. Health care providers can play a significant role in reducing STI risk among older adults by educating them about safe sex practices, offering routine STI screening, and recommending estrogen-containing compounds for managing GSM symptoms. Further research is needed to fully comprehend the impact of menopause on STI susceptibility and to develop targeted interventions.
The increase in STIs among older adults highlights the need for a comprehensive approach that addresses both behavioral and biological factors. By recognizing the unique challenges faced by this population and implementing tailored prevention strategies, we can work towards reducing the burden of STIs in older adults and promoting sexual health and well-being.
