patterns of sexual mixing with respect to social health and sexual characteristics among heterosexual couples in england analyses of probability Sample Survey data
Epidemiology and Infection, 2015Co-Authors: Philip Prah, Catherine H Mercer, Andrew Copas, A Nardone, A M JohnsonAbstract:Patterns of sexual mixing are major determinants of sexually transmitted infection (STI) transmission, in particular the extent to which high-risk populations mix with low-risk populations. However, patterns of mixing in the general population are poorly understood. We analysed data from a national probability Sample Survey of households, the Health Survey for England 2010. A total of 943 heterosexual couples living together, where at least one partner was aged between 16-44 years, were included. We used correlation coefficients to measure the strength of similarities between partners with respect to demographic characteristics, general health, health behaviours and sexual history. Males were on average 2 years older than their female partners, although this age difference ranged from a median of 0 years in men aged 16-24 years to a median of 2 years in men aged 35-44 years. A positive correlation between partners was found for all demographic characteristics. With respect to general health and health behaviours, a strongly positive correlation was found between men and women in reporting alcohol consumption at ⩾3 days a week and smoking. Men typically reported greater numbers of sexual partners than their female partner, although men and women with more partners were more likely to mix with each other. We have been able to elucidate the patterns of sexual mixing between men and women living together in England. Mixing based on demographic characteristics was more assortative than sexual characteristics. These data can better inform mathematical models of STI transmission.

male circumcision in britain findings from a national probability Sample Survey
Sexually Transmitted Infections, 2003Co-Authors: S S Dave, A M Johnson, Kevin A Fenton, Catherine H Mercer, Bob Erens, Kaye WellingsAbstract:Studies from developing countries1 and sexually transmitted diseases clinics in developed countries2 show that male circumcision appears to protect against some ulcerative sexually transmitted infections (STIs) and decreases the risk of HIV infection.3 We used data from the 2000 British National Survey of Sexual Attitudes and Lifestyles (Natsal 2000)—a large scale, stratified, probability Sample Survey—to estimate the prevalence of male circumcision in Britain and investigate its association with key demographic characteristics, sexual behaviours, and reported STI diagnosis. Natsal 2000 methodology details are published elsewhere.4 For the purposes of this investigation, data from targeted oversampling of black Caribbean, black African, Indian, and Pakistani groups (the Natsal ethnic minority boost) were combined with the main Survey data in order to increase the numbers of these respondents included …

male circumcision and sti acquisition in britain evidence from a national probability Sample Survey
PLOS ONE, 2015Co-Authors: Virginia Homfray, Kaye Wellings, Anne M Johnson, Clare Tanton, R F Miller, Simon Beddows, Nigel Field, Pam Sonnenberg, Kavita Panwar, Catherine H MercerAbstract:It is well-established that male circumcision reduces acquisition of HIV, herpes simplex virus 2, chancroid, and syphilis. However, the effect on the acquisition of non-ulcerative sexually transmitted infections (STIs) remains unclear. We examined the relationship between circumcision and biological measures of three STIs: human papillomavirus (HPV), Chlamydia trachomatis and Mycoplasma genitalium. A probability Sample Survey of 15,162 men and women aged 16-74 years (including 4,060 men aged 16-44 years) was carried out in Britain between 2010 and 2012. Participants completed a computer-assisted personal interview, including a computer-assisted self-interview, which asked about experience of STI diagnoses, and circumcision. Additionally, 1,850 urine Samples from sexually-experienced men aged 16-44 years were collected and tested for STIs. Multivariable logistic regression was used to calculate adjusted odds ratios (AOR) to quantify associations between circumcision and i) self-reporting any STI diagnosis and ii) presence of STIs in urine, in men aged 16-44 years, adjusting for key socio-demographic and sexual behavioural factors. The prevalence of circumcision in sexually-experienced men aged 16-44 years was 17.4% (95%CI 16.0-19.0). There was no association between circumcision and reporting any previous STI diagnoses, and specifically previous chlamydia or genital warts. However, circumcised men were less likely to have any HPV type (AOR 0.26, 95% confidence interval (CI) 0.13-0.50) including high-risk HPV types (HPV-16, 18, 31, 33, 35, 39, 45, 51, 52, 56, 58, 59 and/or 68) (AOR 0.14, 95% CI 0.05-0.40) detected in urine. Circumcised men had reduced odds of HPV detection in urine. These findings have implications for improving the precision of models of STI transmission in populations with different circumcision prevalence and in designing interventions to reduce STI acquisition.

sexual function problems and help seeking behaviour in britain national probability Sample Survey
BMJ, 2003Co-Authors: Catherine H Mercer, Kevin A Fenton, Kaye Wellings, Anne M Johnson, Wendy Macdowall, Sally Mcmanus, Kiran Nanchahal, Bob ErensAbstract:The need for estimates of the extent of sexual function problems in the general population has become more urgent given recent debates surrounding the identification and definition of “sexual dysfunction,” the increased availability of pharmacological interventions, and possible changes in our expectations of what constitutes sexual function and fulfilment.1 We report results from the national Survey of sexual attitudes and lifestyles (Natsal 2000). Natsal 2000 was a stratified probability Sample Survey done between May 1999 and February 2001 of 11 161 men and women aged 16-44 years resident in Britain.2 3 The response rate was 65.4%. A computer assisted self interview asked participants about their sexual lifestyles and attitudes. We asked questions about their experience of sexual problems based on those used in the US national health and social life Survey,4 which measured the main dimensions of sexual dysfunction, …
