Coming Full Circle: Our Salt Intakes

I really don’t have very much time to blog these days, so just quick short entries :)

Coming Full Circle: Interesting statistics about sexual relationships and their implications on the spread of HPV

College campuses are increasingly turning into hubs for the spread of STDs as college students take on an increasing number of sexual partners. On average, college students now have around 3 sexual partners a year (Martens et al).

It turns out that male students in general would like to be much more promiscuous than their female counterparts. Undergraduate men expressed a desire for a significantly greater mean number of sex partners than did undergraduate women, over a 1-year period, women, on average, were interested in a single sex partner, whereas the average man expressed a desire for about seven partners (Fenigstein et al, 2007). This result did not change in a statistically significant way for those in serious relationships. What was particularly surprising to me is that males are actually successful in being more promiscious, even among the supposedly more conservative asian subgroup (Arliss 2008). As one can observe from the graph below, males have a much higher percentage of being sexually active with more than 3 partners than females.

The implications above are particularly disturbing for the spread of Human papillomavirus (HPV) infections. HPV is mostly harmless in men but might develop into cervical cancer in women. HPV is estimated to be the most commonly transmitted STD. A recent paper from Sexually Transmitted Disease: Influence of Partner’s Infection Status on Prevalent Human Papillomavirus Among Persons With a New Sex Partner included some extremely surprising statistics.

Women attending university or college in Montreal, Canada, and their male partners (N = 263 couples) were enrolled in 2005–2008. HPV was detected in 56% of women and men. 44% have a type that can lead to cancer. New relationships are when HPV transmission is most likely.

The overall prevalence rate of HPV in the US has never been firmly established, with rates ranging from 14% to 90% being published in peer-reviewed literature (Dunne et al, Revzina et al). Studies however, agree on the trend that a much higher incident rate of HPV is being reported on college campuses than in the general public.

The highest prevalence of HPV was identified among women attending sexually transmitted diseases (STD) clinics and college students, identifying them as target populations for prevention interventions. Conversely, the lowest HPV prevalence was among women in the general population.

With the recently released and much publicized HPV vaccine, many women might be lulled into a false sense of security. For one, the vaccine is only mildly effective on a few strains of the HPV virus, and only particularly effective PRIOR to exposure to the virus (Sawaya et al, 2007).

With grade 2 or 3 cervical intraepithelial neoplasia or adenocarcinoma in situ as the outcome, the difference in risk so far appears to be modest: 219 of 6087 vaccinated women (3.6%) received this diagnosis over an average of 3 years, as compared with 266 of 6080 unvaccinated women (4.4%). The absolute risk difference of 0.8% indicates that 129 women would need to be vaccinated in order to prevent one case of grade 2 or 3 cervical intraepithelial neoplasia or adenocarcinoma in situ occurring during this period. If grade 3 cervical intraepithelial neoplasia or adenocarcinoma in situ were the most relevant outcome, evidence was insufficient to infer the effectiveness of vaccination.

This does not mean that girls should not be given the HPV vaccine, rather that they should still be careful (condoms) and should still have regular screenings, even when vaccinated.

Coming Full Circle: 2009 as “A Turning Point for Personal Genomes”

The Human Genome project was completed at the start of the last decade, and only in the last two years have we really begun to reap the fruits of the immense undertaking. I talk about some of commercial players and legal issues surrounding the wide spread adoption of personal genomic technology in medicine at the First AMA-IEEE Conference on Individualized Healthcare blog.

Incidentally, I’m also on the organizing committee for the conference mentioned above. Consider attending the conference if you are interested in Individualized Healthcare!
