Factors influencing STI transmission in middle-aged heterosexual individuals.

Research has shown that individuals aged 45-64, or the 'middle-aged' population, are at an increasing risk of contracting a sexually transmitted infection (STI). An exploration of the factors that may influence STIs in this age group was carried out to ascertain how to reduce the risk. A critical review identified 14 research papers that considered STIs in middle-aged people. The available evidence base highlighted an under-representation of women, the absence of a consistent definition of 'middle age', and a paucity of specific information on the sexual health needs of this group. Low condom use was found to be a possible contributor to increasing STI rates; men were shown to report particularly low use. Behaviours such as contact with sex workers and sexual encounters abroad were found to be additional risk factors in men, requiring further consideration. The breakdown and formation of relationships during middle age was also identified as a possible area to investigate, as were the behavioural traits of women and associated STI risk. Further research into these areas could facilitate the development of attitudes, knowledge, policy and practice that could help provide better support for individuals affected.
