People are living longer and healthier lives. In recent years, there has been a focus on recognition of ongoing sexual activity among older adults and leading from this, the potential for an increase in diagnoses of sexually transmitted infections (STIs). Data on STI rates, sexual behaviour and factors affecting susceptibility to STIs are discussed.
There is limited published literature in this field and few recent longitudinal studies of STI acquisition in people older than 50 years. Although there is evidence of an increase in incidence, STIs remain rare in older compared with younger populations. Compared with their heterosexual counterparts, older men who have sex with men are at higher risk of incident HIV and some other STIs. The HIV epidemic is ageing as a result of increasing life span and acquisition of HIV at older ages. Improved longevity, evolving societal norms and physiological changes may place older people at risk of HIV and other STIs.
Routine STI screening is not warranted in all older people. Education and prevention strategies for all people at greater risk of HIV, regardless of age are required. Age-appropriate interventions designed to impart knowledge and provide the requisite skills needed to reduce STI risk in older age would be beneficial.
