Demographic and behavioral characteristics of non-sex worker females attending sexually transmitted disease clinics in Japan: a nationwide case-control study

<p>Abstract</p> <p>Background</p> <p>Although number of sexually transmitted infections (STIs) reported in STI surveillance increased rapidly for women in Japan during the 1990s, the sexual behavior of women potentially at risk of STI infection remains unknown.</p> <p>Methods</p> <p>In order to determine the demographic and behavioral characteristics of non-sex worker (SW) females attending STI clinics, female attendees (n = 145), excluding SW, from nine clinics across Japan and female controls from the general population (n = 956), both aged 18-50 years, were compared using two data sets of nationwide sexual behavior surveys conducted in 1999.</p> <p>Results</p> <p>Although the occupation-type and education level were unrelated to STI clinic attendance in multivariate analysis, non-SW females attending STI clinics were younger (adjusted odds ratios [AOR] = 0.94, 95%CI: 0.89, 0.99), and more likely to be unmarried (AOR = 4.11, 95% CI: 1.73, 9.77) than the controls from the general population. In the previous year, STI clinic attendees were more likely to have had multiple partnerships (AOR = 3.09, 95% CI: 1.42, 6.71) and unprotected vaginal sex with regular partners (AOR = 3.59, 95% CI: 1.49, 8.64), and tended to have had their first sexual intercourse at a younger age (AOR = 1.77, 95%CI: 0.89, 3.54) and more unprotected vaginal and/or oral sex with casual partners (AOR = 2.08, 95%CI: 0.75, 5.71). Identical sexual behavior patterns were observed between the female attendees with a current diagnosis of STI (n = 72) and those before diagnosis (n = 73) and between those with a past history of STI (n = 66) and those without (n = 79).</p> <p>Conclusion</p> <p>These results indicate that not only multiple partnerships or unprotected sex with casual partners, but also unprotected vaginal sex within a regular partnership is prevalent among non-SW female STI clinic attendees. The identical sexual behavior patterns observed between female attendees with a current STI diagnosis and those without, and between those attendees with a past history of STI diagnosis and those without, indicate that the result are unlikely confounded with the cases of non-STI infection. This sexual behavior pattern may be predictive of STI infection among young Japanese women and could have contributed to the STI epidemic in women in Japan during the 1990s.</p

Is Homosexuality a Paraphilia? The Evidence For and Against

Whether homosexuality should be described as one among many paraphilic sexual interests or an altogether different dimension of sexual interest has long been discussed in terms of its political and social implications. The present article examined the question instead by comparing the major correlates and other features of homosexuality and of the paraphilias, including prevalence, sex ratio, onset and course, fraternal birth order, physical height, handedness, IQ and cognitive neuropsychological profile, and neuroanatomy. Although those literatures remain underdeveloped, the existing findings thus far suggest that homosexuality has a pattern of correlates largely, but not entirely, distinct from that identified among the paraphilias. At least, if homosexuality were deemed a paraphilia, it would be relatively unique among them, taxonometrically speaking

Sex in Australia: the rationale and methods of the Australian Study of Health and Relationships

Objective: To describe the methods and process of the Australian Study of Health and Relationships. Methods: A computer-assisted telephone interview was developed and applied to a stratified sample of the Australian population. After initially weighting to reflect the study design, the sample was further weighted to reflect the location, age and sex distribution of the 2001 Census. Results: Interviews were completed with 10,173 men and 9,134 women aged 16–59 years from all states and Territories. The overall response rate was 73.1% (69.4% among men and 77.6% among women). After accounting for the survey design and weighting to the 2001 Census, the sample appears broadly representative of the Australian population. Conclusion: The combination of methods and design in the Australian Study of Health and Relationships, coupled with the high response rate, strongly suggests that the results of the study are robust and broadly representative of the Australian population

Sex in Australia: reflections and recommendations for future research

Objective: To review the content, method and process of the Australian Study of Health and Relationships (ASHR). Results: ASHR achieved a large sample, a high response rate and documented the sexual life histories and current sexual health-related knowledge, attitudes and practices of the Australian population aged 16–59. Its cross-sectional nature limited our ability to partition observed variation between age and time despite clear evidence of both age-related and cohort-related changes in sexual practice. Similarly, its reliance on a sample of individuals reporting on their sexual experiences rather than a sample of sexual relationships or encounters and their participants limits our ability to understand the dynamics of those relationships and encounters. Finally, our understanding of sexuality in Australia could have been improved through qualitative studies with a subsample of ASHR participants. Conclusion: ASHR represents a significant contribution to our understanding of sexual health-related knowledge, attitudes and practices in Australia
