Medical Research: What should clinicians and patients take away from your report?
Dr. Franco: Our findings of oral transmission of human papillomavirus (HPV) infection in men are part of a larger molecular epidemiologic study called ‘HPV Infection and Transmission among Couples through Heterosexual Activity’ (HITCH) cohort study. The focus of the HITCH study is to understand how HPV is transmitted within couples via sexual contact and other behaviors. We measure the presence of this virus using highly-sensitive molecular assays for HPV DNA in the genital surfaces (vagina and penis), oral cavity, and hands. We also take a blood sample to look for the presence of antibodies against HPV. We take multiple samples over a period of two years at pre-scheduled visits. We have previously published results focused exclusively on genital transmission. The present report is the first in the HITCH study to look at what happens in terms of characteristics that place male participants to be at risk of oral HPV infection.
To our knowledge, this is the first study to show a high risk of oral HPV infection among men whose female partners had a genital or oral HPV infection, suggesting that transmission may occur through oral or genital routes. We looked at transmission for 36 individual HPV genotypes, which improved our ability to study risk determinants. Risk was also significantly higher among men who had ever smoked, had a high number of lifetime sex partners, or were in non-monogamous relationships. Our results are largely consistent with previous studies that have found male sex practices and smoking to be the most significant risk factors for oral HPV infection.

Medical Research: What are the main findings of the study?
Dr. Temple: Through previous research, we know that teen sexting is related to actual sexual behaviors, but we did not have any information on the temporal link between these two behaviors.
In short, we found that teens who sexted had 32% higher odds of being sexually active over the next year relative to youth who did not sext – this was even after controlling for history of prior sexual behavior, ethnicity, gender, and age. We also found that active sexting (actually sending a naked picture to another teen) mediated the relationship between passive sexting (asking for or being asked for a sext) and sexual behaviors. In other words, while sending a sext was predictive of subsequent sexual behavior, asking for/being asked for a sext was only associated with sexual behavior through its relationship with active sexting.

Medical Research: What are the main findings of the study?
Dr. Schabath: Overall, the results from these analyses demonstrated that men who consumed the highest amounts of alcohol were associated with an increased risk for genital human papillomavirus (HPV) infections.

MedicalResearch.com: What are the main findings of the study?
Dr. Alexander: Adolescents are reluctant to talk about sex with their doctors and won't raise the topic with their doctors. For physicians, there are common and valid barriers to talking about sexuality with adolescents, including time pressures and discomfort with the topic. Two-thirds of adolescents in our study had some sexuality talk during their annual visit, lasting 36 seconds long. Girls, African Americans, and older teens were more likely to receive sexuality talk. Additionally, longer visits and visits where the physician talked confidentially with their adolescent patient were more likely to have sexuality talk. Our study suggest that sexuality conversations in annual visits can be improved.

Catherine H. Mercer Ph.D.

MedicalResearch.com: What are the main findings of the study?
Dr. Mercer: Firstly, the National Surveys of Sexual Attitudes and Lifestyles, Britain’s nationally-representative surveys of sexual behaviour (or Natsal for short), have captured substantial changes in sexual attitudes and lifestyles over the past 60 years, having collected data from over 45,000 people born between the 1930s and the 1990s – a period spanning much of the 20th Century.
Secondly, the recent changes in behaviour that we have observed - so over the past decade - have however been considerably more marked for women than men, with the gender gap in reported behaviour narrowing, and in some cases, disappearing altogether.
Thirdly, we’ve seen a greater acceptance of more diverse sexual lifestyles, such as same-sex sexual partnerships, but greater intolerance of what many people might consider as ‘disrespectful’ sexual partnerships, including non-exclusivity in marriage.

MedicalResearch.com: What are the main findings of the study?
Dr. Mitchell: We explored the distribution of sexual function in the British population using a probability sample survey (the third National Survey of Sexual Attitudes and Lifestyles [Natsal-3]) of 15 162 individuals aged 16–74 years. We measured sexual function using the Natsal-SF, a novel validated measure, which assessed problems with individual sexual response, sexual function in a relationship context, and self-appraisal of sex life.
Men and women in the oldest age groups surveyed (55 – 74) were more likely to have low overall sexual function than those in the youngest age group (16 – 24). After taking account of age differences, low sexual function was associated in both men and women with being unemployed, with current depression, and with poor general health. It was also associated with higher numbers of lifetime partners (women only), paying for sex (men only), and reporting same-sex partners, as well as with other aspects of sexual health, such as being diagnosed with an STI and experiencing sex against their will.
Low sexual function was associated with relationship breakdown, and with people not being happy with their relationship. Within relationships, the most common problem was an imbalance in level of interest in sex between partners, which affected around a quarter of both men and women. Just under one in five men and women said their partner had experienced sexual difficulties in the last year, and this proportion increased with age, particularly among women.
Lack of interest in sex was one of the most commonly reported problems for both men and women, affecting three in every twenty (15%) men, and with women twice as likely as men to say that this had been an issue in the last year. Difficulty reaching climax (16%) and vaginal dryness (13%) were among common problems for women; and reaching a climax more quickly than desired (15%), and difficulty getting or keeping an erection (13%) among men.

MedicalResearch.com: What are the main findings of the study?
Dr. Field: This study, published in The Lancet on Tuesday 26 November, reports data from the third National Survey of Sexual Attitudes and Lifestyles (Natsal), interviewing over 15,000 participants aged 16-74 years, to systematically assess the association between people’s health and their sexual lifestyles in Britain. The key findings from the study are that close to one in six (17%) of men and women feel that their health had affected their sex life in the past year. This rises to three fifths (60%) among men and women who say that they are in bad health. However, only a quarter of men (24%) and under a fifth of women (18%) who say that ill-health affects their sex life had sought help from a health profession, usually a family doctor.
