Background: STI prevalence is changing. With society aging, life expectancy increasing and changes in sexual practices, STIs in senior citizens are of interest from economic, health related and social burden perspectives. Few studies on STIs in older men greater than 60 years of age exist, hence, a need to obtain further information about this subpopulation.
Method: A retrospective study of data over 13 years was performed looking at various characteristics of men over 60 years visiting Clinic 275. STI diagnoses of Gonorrhea, Chlamydia, Syphilis, Non-Specific Urethritis (NSU) and Warts were evaluated. A comparison was made between the prevalence of STIs between older heterosexual and Men who have sex with Men (MSM). Further comparison was made between these men and their younger cohort (aged 18-59). Data analysis was performed using STATA (version11).
Results: During the study period, 752 men, 60 years and older, visited the clinic. At first presentation visit, there were significant differences in gonorrhea and chlamydia prevalence between heterosexuals and MSM (p <0.05). Differences in prevalence for syphilis, NSU and warts were insignificant. Compared with younger heterosexuals, heterosexual older men were less likely to have chlamydia and warts and more likely to have positive syphilis serology. There were insignificant differences in STI rates between younger and older MSM. Older MSM were less likely to have previous HIV testing and were from less disadvantaged areas compared to younger MSM. Older heterosexual men were less likely to have more than one partner in previous 3 months compared to younger heterosexuals.
Conclusion: We believe this is the only study in South Australia addressing the epidemiology of STIs and characteristics of older men visiting a public STD clinic. STI rates in older MSM are similar to younger MSM but older MSM are less likely to be tested for HIV. There is need to improve HIV testing amongst older MSM.
Conducting clinical audits in the context of continuous quality improvement (CQI) programs in Aboriginal Community Controlled Health Services (ACCHS) has provided valuable information regarding what factors facilitate or create challenges to improving outcomes in sexual health service delivery.
Homosexual men are at increased risk of anal cancer. Screening and treatment of the precursor, HSIL, has been advocated by some, but screening is not recommended in widely-accepted guidelines. We aimed to describe the prevalence, incidence, and clearance rates of anal HSIL, and association with human papillomavirus (HPV) status, in a community-recruited cohort of homosexual men.
Since 2009, the Victorian syphilis enhanced surveillance system has been collecting HIV status and syphilis re-infection status for infectious syphilis cases. Baseline data from 2009 showed that 31% of the infectious syphilis cases were HIV positive and 18% reported were re-infections. This suggested that syphilis transmission among a pool of HIV positive MSM was making a considerable contribution to the syphilis epidemic in Victoria. We analysed the data from 2009 to 2012 to determine whether this pattern of transmission is continuing. Notification data for infectious syphilis between 2009 and 2012 were reviewed by HIV infection status, syphilis re-infection status and risk factor exposures.
HIV positive gay men have high rates of cigarette smoking. The risks of smoking in addition to the elevated risk of cardiovascular disease and some malignancies in people with HIV means smoking cessation interventions should be prioritised.
We investigated the association between chlamydia detection and stage in the menstrual cycle to investigate whether chlamydia detection was higher at different stages of the cycle. Electronic medical records for women attending Melbourne Sexual Health Centre March 2011 - 31st December 2012, who were tested for chlamydia by nucleic acid amplification of high vaginal, cervical, or urinary samples, and who recorded a date of last normal menstrual period (LNMP) between 0-28 days were included in the analysis. Logistic regression was used to calculate OR (95%CI) for the association of chlamydia with menstrual cycle adjusted by demographics and behavioural variables.
Chlamydia is prevalent among young Australians. The latest national surveillance report (2011) shows a rate of diagnosis of 1400 per 100,000 population aged 15-29 years. In Victoria, the number of notifications in 2011 was 19,238; 81% in 15-29 year olds; however notifications continue to rise in all age groups. International evidence suggests chlamydia reinfection is responsible for a substantial burden of infections. Given the associated health risks, monitoring reinfection in the population is important to understand disease burden and evaluate interventions. We describe the rate of reinfection and time between infections in Victoria, 2004-2011.
