Changes in sexual behavior among high-school students over a 40-year period

Seroprevalence of sexually transmitted infections over 44 years - A cross-sectional study in Sweden

BACKGROUND

Sexually transmitted infections (STIs) may cause substantial individual suffering and a large economic burden for society. This study examined the seroprevalence of Chlamydia trachomatis, Mycoplasma genitalium, herpes simplex virus (HSV) types 1 and 2, and several human papillomaviruses (HPV) in the Swedish population over time.

METHODS

The study population consisted of 30-year-old women attending maternity care, and 50 year-old men and women attending health check-ups, from 1975 to 2018. Antibody status was determined by multiplex serology and quantified using median reporter fluorescence intensity (MFI).

RESULTS

A total of 891 samples were analysed (519 from 30-year-old women, 186 from 50 year-old women and 186 from 50 year-old men). Of these, 41.5% showed seropositivity for Chlamydia trachomatis, 16.7% for Mycoplasma genitalium, 70.5% for HSV-1, 14.9% for HSV-2, 13.2% for high-risk HPV, and 8.3% for low-risk HPV. Seropositivity for Mycoplasma genitalium, HSV-1 and especially Chlamydia trachomatis decreased over time.

CONCLUSIONS

There was a decrease over time in Chlamydia trachomatis seroprevalence, probably due to contact tracing, testing and early treatment; this might also have affected Mycoplasma genitalium seroprevalence. Despite the reduction, seroprevalences are still high, so continued and new efforts to reduce STI incidence are essential.

Sexuality education for young people in Germany.Results of the 'Youth Sexuality' representative repeat survey

The Federal Centre for Health Education (BZgA) has been conducting the 'Youth Sexuality' representative survey on a regular basis since 1980. This continuous monitoring generates insights into the sexual and reproductive health of young people in Germany and constitutes an important basis for evidence-based health communication. A total of N=6,032 young people between the ages of 14 and 25 participated in a combination of oral and written interviews (Computer Assisted Personal Interviews (CAPI)). As primary sources of knowledge for, adolescents state that they obtain information through school lessons (69%), personal discussions (68%), and the Internet (59%). In addition to these sources, professional gynaecological counselling and sexuality education at home are also important sources of information. To what extent trusted contact persons are available in the family depends heavily on the adolescents' sociocultural backgrounds. Providing information and disseminating knowledge to young people in the field of sexual and reproductive health is organised intersectorally in Germany. In this way, it is possible to also reach those who do not have any contact persons at their disposal in their direct family. Maintaining and strengthening the current commitment in promoting sexual health is of key importance, as only this will ensure the next generation's sexual and reproductive health, and provide an evidence-based counterbalance to anecdotal information, especially in the digital domain.
